    A vacuum suspension for handling large size plates, especially concrete building parts that are still of low strength and brittle. The suspension is a stiff case forming the carrying structure frame having the vacuum pumps on its top. The inside of the case is divided by a baffle into a work vacuum chamber and decompression chamber. The latter is separated by a holed plate from a foam rubber sheet, having suction cups shaped therein. The holed plate of the suspension has self controlled fluidic disk valves of low inertia.

    专利说明:

    The invention relates to vacuum gripping devices for transporting plates, especially large ones.
    A cargo-slip device is known, made in the form of a vacuum-drawing head, having several separate chambers with valves that connect 11 with a common chamber. Each section has a ball valve, a locking hole, which communicates the chamber of the section with a common chamber in the event that the product does not overlap this chamber 1.
    The complex design of the device, the unreliability of ball valves, the need to create and maintain very low pressure drops are the cause of frequent leakage, limiting their use and reducing performance.
    It is also known a vacuum zoosvatny device for transporting plates, comprising a box-shaped body with a lower perforated plate, separated by a vacuum body partition and decompression chambers
    and self-steering valves located in the perforations of the C2 plate.
    In this device, the normal operation of the valves requires the creation of a large suction force distributed at a considerable distance on the surface of the portable product, and its use for working with products having a low degree of solidification, for example, with pressed concrete elements, of coins attached. lead to their deformation and destruction.
    The purpose of the invention is to increase the reliability of the device in operation by ensuring the maximum distribution of the suction forces, due to which it is possible to operate with fragile elements with a low degree of solidification.
    This goal is achieved by the fact that each self-controlling valve is made in the form of a rod with a mushroom-shaped lower part with a limiter fixed on the upper part of the rod, with bar guides installed in the middle of the rod.

    In addition, each rod is made of plastic, for example polypropylene, and has a thread for the stopper in the upper part, and a sealing cap made of an elastic material, for example rubber, is fixed on the lower mushroom part, the volume of the decompression chamber is up to 0.2. volume of the vacuum chamber and is equal to the sum of the free volumes of suction chambers. . FIG. 1 shows the proposed device, a general view, in section in FIG. 2 — A self-steering valve in the suction chamber. The device contains vacuum pumps 1, located on the outer surface of a rigid metal body 2, divided inside into two parts by a steel partition 3, best of all convex upwards. The upper part 4 (vacuum chamber) is connected to the pump 1. The lower part 5 (decompression chamber) is connected to the vacuum chamber 4 by means of vacuum solenoid valves b, and to the atmosphere by air ducts to the valves 7. The bottom of the decompression chamber is a metal film 8 pasted over with an elastic material plate 9, for example, a micro-sheet, in which suction chambers 10 are made with self-controlling valves 11 located therein. Each valve 11 has a stem 12 with a mushroom-shaped lower part, Made of plastic, limiter 13 of stroke and at least one rod guide 14, providing a symmetrical valve installation. A sealing cap 15 is put on the mushroom-shaped part of the rod 12. When the vacuum device is in operation, it is hung on the hook of the lifting mechanism (not shown) and transported to the place of loading. By switching on the vacuum pumps, the necessary vacuum is created in the vacuum chamber 4 and, when the valves 6 are opened, due to the created vacuum in the decompression chamber 5, they ensure the capture and transportation of the elements to their destination. At the place of unloading, valves 6 are closed and valves 7 are opened, which ensures release of the part. It has been established experimentally that the ratio of the volume of the decompression chamber to the volume of the vacuum chamber is 0.2, and the sum of the free volumes of the suction chambers must be less than or equal to the volume of the decompression chamber. The design of the gripping device according to the invention ensures the required flow dynamics and the creation of the required pressure change in the suction chambers with a small inertia of self-steering valves, ensures complete reliability of the device operation. 1. Vacuum gripping device for transporting slabs, mainly concrete, large-sized with a low degree of concrete hardening, containing a block of vacuum pumps mounted on a box-shaped housing with a lower perforated slab glued over with an elastic material, such as a microresin, separated by a vacuum partition wall and a decompression chamber connected by a vacuum solenoid valve and suction chambers formed in an elastic material, in which the control valves, characterized in that, in order to increase its reliability in operation, each self-control valve is made in the form of a rod with a mushroom-shaped lower part with a limiter fixed on the upper part of the rod, with rod guides installed in the middle part of the rod. 2. The device is in accordance with claim 1, which is made in that the rod is made of plastic, for example polypropylene, and has a thread for the stopper in the upper part, and a sealing cap made of elastic material, for example, rubber, is fixed on the lower mushroom-shaped part. 3. The device according to claim 1, characterized in that the volume of the decompression chamber is up to 0.2 times the volume of the vacuum chamber and is equal to the sum of the free volumes of the suction chambers.
