    专利说明:

    [0001] The present invention generally relates to hollow charges, which are hollow explosive charges for concentrating the effect of the energy of an explosive and in particular linear hollow charges which are also known in the art. the terms of linear hollow cutting charges (LCC).
    [0002] An LCC has a coating with a generally shaped profile, V and a variable length. The explosive is then loaded behind the liner and the explosive is wrapped inside a suitable material that serves to protect the explosive and to confine it (tamp down), at the time of the detonation. The charge explodes at some point in the explosive above the top of the liner. The detonation projects the coating to form a continuous, planar jet. The jet cuts the material in its path, to a depth depending on the size of the load and the materials used in the load. LCCs are used, for example, in the cutting of rolled steel beams and other structural targets, such as in the controlled demolition of buildings. Existing user-made linear cut-off fillers require the user to stuff the explosive into the load, ensuring that the explosive is in good contact with the coating. This requires considerable care and time and requires the use of some type of stuffing tool. The present invention seeks to provide improvements over existing hollow linear cutting charges.
    [0003] According to one aspect of the present invention there is provided a user-fillable linear hollow charge comprising an elongate body and a liner, wherein the filler further comprises a cavity adjacent to at least a portion of the liner for receiving the substance the cavity comprising two elongated channels extending adjacent to the coating, the body having a distribution opening between the channels for receiving the explosive substance. In another aspect, there is provided a user-replaceable linear hollow charge comprising a body and a generally V-shaped liner, wherein the filler further comprises a cavity adjacent the liner for receiving the explosive substance, the cavity comprising two elongated channels extending adjacent to the coating, the cavity having a distribution opening between the channels for receiving the explosive substance.
    [0004] The channels may extend generally parallel to the coating. Another aspect provides a user-replaceable linear hollow charge, comprising a body and a coating provided on or by the body, wherein the load further comprises a cavity adjacent the coating for receiving the explosive substance, and an opening dispensing to allow the user to fill the cavity. The aperture may include a trough, a passage, a hole, a gap, an opening, a gap, an orifice, a slot, a window, an incision, a fill mouth, or the like. In some embodiments, the aperture extends along the entire length of the load, for example, by being an elongated gap between the rear walls of a pair of channels. The opening may be adapted to receive blocks (complete blocks and / or cut blocks) of explosive substance. The body of the load can be shaped and shaped so that the user simply slides fully packaged explosive blocks into the body so that they are automatically held in place. Depending on the shape of the blocks and the channel, the user may need to cut the blocks to be the right size for the channel. In some embodiments, the channel corresponds to the known and predetermined block sizes.
    [0005] The key to block-receiving embodiments of this type is to match the proportions of the cavity to the size of the standard explosive block. In one embodiment, a filler formed in accordance with the present invention was loaded in a few seconds by sliding complete blocks of explosive PE7 and three half-blocks of PE7 which were easily shaped to fit the cavity. Not having to unpack the explosive or reform or stuff the explosive is a considerable advantage. It has also been noted that with certain explosives, such as C4, they are packed at a high density, but reforming the explosive when unpacked causes a density reduction of 1.6 g. / cm3 at 1.3 g / cm3, which fillers formed according to the present invention can avoid. In some embodiments, the load has a sealed projection unit. For example, in one embodiment, the filler may be a steel-welded diamond-shaped cross section with the welded ends that resist water pressure and prevent water from preventing the formation of the jet. The coating may be a separate component, for example a copper coating with an angle between 70 and 100 degrees. In other embodiments, the coating may be an integral part of the body. The coating may define a cavity portion. The load may further include a cover to cover the opening. In some embodiments, a plastic cover is provided. The body may include means for receiving a coating at a plurality of positions. For example, a multitude of rails within which a coating can slide, can be provided on or by the body. This makes it possible to modify the channel width to accept the different block sizes, for example PE7 or C4. The load may further include an end cap. The end cap may, for example, receive an initiator, in use. It may also, for example, include means for locking the load with other such loads in a network. The end cap may be attached to one end of the body, for example, using a screw fastener or the like. The fillers can be made from folded metal or extruded from metal or plastic. The body may, for example, be formed from a metal or a metal alloy material, for example aluminum that can be extruded into an elongate form.
    [0006] Depending on the material from which the filler is formed, in some embodiments an elongate filler may be cut to length, for example with a hacksaw.
    [0007] Another aspect provides a body for a linear hollow charge, comprising an elongate body for receiving a coating, wherein the load further comprises a cavity for receiving the explosive substance to be adjacent to at least a portion of a coating, use, the body having a dispensing aperture for receiving the explosive substance in the cavity. The present invention also provides a filler as shown and described herein and filled with the explosive substance. The explosive substance may be in block form. The present invention also provides a method for charging a linear hollow charge with an explosive substance, as shown and described herein. Different aspects and embodiments of the invention may be used separately or together. Other particular and preferred aspects of the present invention are set forth in the appended independent and dependent claims. The features of the dependent claims may be combined with the features of the independent claims if necessary and in combination with others than those explicitly set forth in the claims. The present invention will now be more particularly described, by way of example, with reference to the accompanying drawings, in which: FIG. 1 is an exploded perspective view of a linear cutting hollow charge formed in accordance with the present invention; Figure 2 is a sectional view of the load of Figure 1; Figure 3 is an enlarged perspective view of one end of the load of Figure 1 shown partially assembled; Figure 4 shows the end of Figure 3 fully assembled Figures 5 to 12 are a sequence of images showing how the explosive is added incrementally to a load; Fig. 13 is a perspective view of a filler formed according to an alternative embodiment and shown with an end cap removed; Fig. 14 is an enlarged view of one end of the filler of Fig. 13; Fig. 15 is a sectional view of one end of the load of Fig. 13 when mounted with an end cap; Fig. 16 is a perspective view of a filler formed according to another embodiment and shown with a withdrawn end cap; Fig. 17 is a perspective view of the load of Fig. 16; Fig. 18 is an enlarged view of one end of the load of Fig. 17; Fig. 19 is a section of an end region of a load formed according to another embodiment; and Fig. 20 is a section of the load of Fig. 19 when mounted with an end cap.

Unless otherwise defined, all terms (including technical and scientific terms) used herein should be interpreted as is customary in the art. It should further be understood that terms of common usage should also be interpreted as is customary and not in an idealized or overly formal sense unless otherwise indicated. Firstly, with reference to FIGS. 1 and 2, there is shown a linear cutting hollow load generally indicated by reference numeral 10. The load comprises an elongated body 15 which, in this embodiment, is formed with a section U-shaped trough-shaped body generally square 20 with a base 21 and two parallel sidewalls 22, 23. A pair of elongated inclined struts 24 extend longitudinally and assemble the base 21 and the respective walls 22, 23. Extending, inclined, from the free ends of the sectional sidewalls 22, 23, are elongated channel flanges 35A, 35B generally L. The short flap 40A, 40B of each channel flange extends to from the respective walls 22, 23 and the long tab 45A, 45B extends at a distance and generally parallel to each side of the coating section 30 (see below). This forms a generally V-shaped cavity 50 in the form of two elongated channels 50A, 50B. The tabs 40A, 40B terminate with truncated flanges 41A, 41B. The tabs 45A, 45B each terminate at an inclined flange 47A, 47B which are spaced from each other to define a chute 55. A generally V-shaped linear cut-off load liner 30 is provided and relies on or against the truncated flanges 41. It should be noted that the liner 30 effectively defines a wall of the cavity 50. Referring now also to FIGS. 3 and 4 and as described in more detail below, the explosive substance can be loaded into the cavity 50 by the chute 55. The explosive is held in place by a cover 60 (in this embodiment, formed from a plastic material) and end caps 65 (a Only one is shown in this embodiment, made from a plastic material) which is held in place using bolts 70. The cover includes a channel 61A, 61B extending along each defined side There are provided recesses which mate with the flanges 47A, 47B to mount the cover to the body 15. Holes 75 are provided on the lower edge of the body section 20 to accommodate the bolts to hold the caps thereon. end (depending on the length at which the body is cut) as well as provide attachment points for the load. Figures 5 to 12 are a sequence of images illustrating the manner in which the explosive substance blocks are added incrementally to a load. A complete block 80A of plastic explosive material is first loaded into each of the channels 50A, 50B by the chute 55 to begin filling the cavity 50 (FIGS. 5 to 8), followed by a half-block 80B (FIGS. to 11).
    [0009] It should be noted from Fig. 12 that in this embodiment only the end piece 80C of explosive must be manipulated and reformed to fill the cavity (as shown in Fig. 3). With the last 5 explosive plastic, this is very fast and very easy. The key here is speed. If the charge can be charged faster then it is easier to use. Figures 13 to 15 show a load 110 formed according to an alternative embodiment. The load 110 is similar to the load 10 of FIGS. 1 to 12. The body cavity includes longitudinal flange rims 141 for receiving a generally chevron-shaped cut-off load liner 130. Spacers are not expected. End caps 165 are provided to fit on each end of the elongated body. The end caps are provided with holes 166 for receiving fasteners (not shown) for attachment to the body. Figures 16 to 18 show a load 210 formed according to an alternative embodiment. The load 210 is similar to the load 110 of Figures 13 to 15 except that in this embodiment, the coating is replaced by a generally box-like coating 231 which is supported on the flanges 241. In Figures 19 and 20 Another embodiment is shown in which a load 310 very similar to the load 210 is provided with an elongate support 332 comprising a generally V-shaped support 333 in section on which a box-like coating 331 is based. (together with ledges 341).
