    Quick connect apparatus for headbox components in a paper making machine, e.g., apparatus to quickly connect and disconnect the equalizing chamber portion of the air cushion damper from associated distribution header and turbulence sections of the machine, include an elongate locking rod extending over a substantial portion of the end region of the components to be attached, the locking rod being mounted for longitudinal movement. The locking rod is provided with spaced locking portions adapted to lockingly engage correspondingly spaced portions of adjacent components to which said component is to be attached. The components are quickly connected in one embodiment by the longitudinal movement of the elongate locking rod or, in another embodiment, by the rotational movement thereof, whereby the locking portions on the rod are moved into and out of locking engagement with the corresponding spaced locking portions of the other component.

    f10 The invention relates to paper machines, in particular to quick-acting coupling devices for removable fastenings of pneumatic dampers, distribution manifolds, covers, bottoms and other assemblies of headboxes of paper machines.;. A fast-acting connecting device for detachable mounting of pneumatic dampers, distribution manifolds, bottom covers and other headboxes of papermaking machines is known, including fixing elements mounted on supporting surfaces 15 of the mating front and rear surfaces in the direction of movement of the suspension suspension. the element and means for moving the assembly relative to the case of the pressure box iflj. However, the known high-speed connecting device is ineffective in operation. The aim of the invention is to increase the efficiency in the work. This goal is achieved by the fact that in a high-speed coupling device for detachable mounting of pneumatic dampers, distribution manifolds, covers, bottoms and other nodes of the drawers of paper-making machines, including those installed on the supporting surfaces of the conjugate front and rear directions of the suspension body fasteners and means for moving the knot relative to the headbox case, each of the fasteners with Osota of the locking rod, which runs across the entire width of the headbox and the base mounted on one of the mating surfaces, and mounted on the other supporting surface of the locking pin position, and the locking rod is made with alternating protrusions along its length with a working surface and grooves between them and has a drive of reciprocating movement of it across the width of the headbox, made in the form of a handwheel, motor mover or other equivalent means, retainer is provided with retaining tabs contacting the working surface with the cam lobe surface by Sturge locking n 1 Thus the lock rod has a rectangular cross section. In addition, each of the slots of the locking rod in its cross section has a slope towards the base of the rod. . Figure 1 shows the proposed device, a General view; figure 2 - section aa in figure 1; Fig. 3 is a sectional view of the connecting device between the compensation chamber and the turbulent part; in fig. - fastening of the locking tabs. The distribution manifold 1 of the paper machine contains a distribution tube 2 which tapers in the direction of flow and has distribution tubes 3. The distribution tubes 3 communicate with the box of the pressure box 4 connected to the damping means 5. Turbulent is located in the direction of the flow of the pulp a pipe 6, separated from the body by a lattice 7. The case of the pressure box is bounded by the bottom wall 8 and the top wall 9. In the top wall 9 there is a window through which the pulp can It is a one to a level determined by the level S. overflow wall 10 of housing part 11 of the headbox. The bottom wall 8 is part of the box girder 12. The left wall of the pressure box casing contains the connecting beam 13, and the right wall - the connecting beam TA, which form, between. bout angle L, open in the direction of removal of F. A support 15 is attached to the beam 14, behind which there is a wedge. Dimple groove. Similarly, at the bottom of the beam 13 there is a projecting part 16 with a wedge-shaped groove. The upper end 17 of the beam 13 is made wedge-shaped, and the beam I has a wedge-shaped part 18. The headbox housing part 11 has a bevelled part 19 below, which engages with part 16. Similarly, the bevelled upper part 17 enters the rear end of the protruding part 20 beams 13. Thus, respectively, between beams 14 and 22, joints are formed using parts 15, 23 and 18, Zk. Thanks to the sloped wedge; The surfaces in both joints, the joints 25 and 26 between the beams 13, 21 and 1, 22 are hermetically sealed mainly due to their own weight of the hull part 11. These joints 25 and 2b between the beams have elastic sealing strips 27 and 28 and for quickly separating and securing the body part 11 on the upper and lower edges of the beam 21 and fastening elements. Each fastener consists of a locking rod 29, which extends across the entire width of the housing of the head box A. A screw 30 with a thread 31 is fixed at one end of the rod 29. The screw 30 has a sleeve 32 turned, which is driven by the handwheel 33. The sleeve 32 is mounted with an RO sleeve 3 fixed rigidly to the frame by means of an i flange 35. The handwheel 33 (or its equivalent drive) is used to move i the locking rod 29 in the direction Arrows F. The locking rod 29 has a rectangular transverse semen and is provided with B-grooves having an inclined base. On the ledges 37. through screws 38 fixed one hundred. porous pads 39 in contact with the working surface with the working surface of the protrusions of the locking rod 29Each of the notches of the ZB of the locking rod 29 in its cross section has a slope in the rod of the base of the rod. The locking rod 29 is installed in guides tO attached with screws 1 to the beam k2. The locking tab 39 is fixed on j-protrusion 37 by means of a screw 38 having a thread 3 Elastic connection; a locking tab 39 is provided; the fact that the screw 38. has a cylindrical part C without a thread, and in the corresponding place in the groove 36 - a washer 5 and two opposite spring washers 6 and 7.., The damping means 5 has stiffening ribs. The device works as follows. When the device is in the locked position, the locking tabs 39 abut their surfaces against the upper face of the locking rod 29, the grooves 36 remain between the tabs 39. When the locking rod 29 is opened, it is moved in the longitudinal direction using the handwheel 33. At the same time, the B3 grooves coincide with legs 39, as a result of which the body part 11 is raised in the direction of the arrow Fj. The direction FJ and the angle of inclination of the base of the grooves 36 are chosen such that the locking tabs can pass through the grooves 6. In the unlocked position, when part 11 is pushed to the side, the locking rods 29, located on top of the head box 4, move away from part 11, while time, as the lower locking rod remains mated with the beam 13, and the locking tabs 39 move away with part 11. The upper locking rods 29 are constantly supported by the guides kQ. After the housing part 11 is detached, an access is formed to clean the distribution pipe 2 and the turbulent pipe 6. Then, turning the handwheel 33, return part 11 of the housing to its place, the inclined surfaces of the B3 slots in the locking rod 29 guide the rod under the tabs 39 and clamp it. Thus, the high-speed coupling device ensures high efficiency in operation.
