Description

The invention relates to the field of special testing equipment intended for testing products containing explosive materials (BM) for resistance to impact loads on pile stands. The invention can also be used in other types of testing equipment, for example, in lifting mechanisms (cranes, winches) used in testing products with a VM for resistance to falling onto a rigid base (concrete, etc.).

Known two-component remote manipulator (RF patent No. 2363570; IPC B25J 1/08, 3/04, G21F 7/06, published in Bulletin No. 22 of 08/10/2009) containing a control arm and an executive arm that are not connected to each other directly by a mechanical transmission, however equipped with an interface system containing a control part and a drive part. Management takes place behind the protective wall.

A gripping device is known (RF patent No. 2245585; IPC G21C 19/10, 19/26, published in Bulletin No. 3 of January 27, 2005) for manipulating components located in the processing zone from a control station separated from the processing zone by a partition. In the known device, a hollow shaft is passed through the baffle plate, on the end of which protrudes into the machining zone a gripper adjustable by the traction element is installed, the traction element passing inside the hollow shaft and connected to a control element mounted on the hollow shaft portion protruding into the processing zone.

Known devices are designed to manipulate products, they are controlled remotely. The devices have a complex structure.

The objective of the invention is to develop a device for testing products containing explosive materials, ensuring the safety of personnel.

The technical result achieved by using the present invention is the simplicity of the design, ensuring the safety of personnel when carrying out work hazardous to life and health.

The technical result is achieved by the fact that the proposed device for testing products containing explosive materials located in the processing zone, controlled from the partition of the operating zone separated from the processing zone, includes an anvil, a hammer with the test product located on it, a gripping device through which the possibility of raising and lowering the hammer through a cable connected to an electric motor, the control panel of which is located in the operating area, and two small cables, one end of which is closed slivers on the coupling, the other connected to a rope for manual remote control of the operating zone. The device is equipped with a base on which an electric motor, a hammer, a cable rotation unit, a cable and a gripping device are fixed. Two blocks of rotation of small cables are fixed on the anvil. The partition is equipped with a viewing window. The hammer is equipped with a loop, and the gripping device is made in the form of two fingers, capturing the loop.

A device for testing products containing explosive materials is made in a simple design. At the same time, a simple design of high reliability and ease of maintenance is achieved. The use of regulatory components passing through the partition, allowed to control the release of the gripper, not being in the processing zone, which ensured the safety of personnel.

This design allows testing products containing explosive materials (BM) and taking information on the impact process — duration and amplitude using the oscillographic method, since at the moment the electric hoist electric motor is turned on, switching currents lead to premature start of the recording equipment.

Figure 1 shows a diagram of a device for testing products containing explosive materials. Figure 2 shows a top view of a diagram of the device. Figure 3 shows a gripping device. Designations of positions: 1 - tested product, 2 - hammer lifting and lowering cable, 3 - equipment, 4 - gripping device, 5 - hammer, 6 - rotation blocks, 7 - anvil, 8 - cable for manual remote control, 9 - electric motor, 10 - electric motor control panel, 11 - handle, 12 - straps, 13 - pipe, 14 - small cables, 15 - base, 16 - cable rotation unit, 17 - viewing window, 18 - partition, 19 - loop, 20 - fingers, A - processing zone, B - operating room, C - connection point of small cables 14 and cable for manual distance Management 8.

A device for testing products containing explosive materials consists of a self-releasing gripping device 4, two rotation units 6 with straps 12, a cable for manual remote control 8 with a handle 11. The straps 12 with rotation units are bolted to the anvil 7. Two small cables 14 are fixed diametrically from one end on the gripper 4, their other ends are connected to a cable for manual remote control 8. Small cables 14 are thrown through rotation blocks 6. Blocks 6 have protective devices, preventing protecting the loss of cables from the grooves of the blocks of rotation. The cable for manual remote control 8 passes through a pipe 13 into the operating room (area) of the staff. In zone B at the end of the cable for manual remote control 8 there is a handle 11. The length of the cable for manual remote control 8 is such that it allows the hammer 5 with the test product 1 to be raised to an angle from 0 ° to 90 °.

A device for testing products containing explosive materials is located in processing zone A and operates as follows. The fingers 20 of the gripping device 4 capture the loop 19 of the hammer 5 with the test product 1 located on it, fastened in a snap 3, and lifts it to the desired angle when the cable 2 interacts through the electric motor 9, which is switched on by the control panel 10. The control panel 10 is located in the operating area In, located behind the partition (wall) 18. On the partition 18 there is a viewing window 17. When lifting the hammer 5, small cables 14 are pulled out and followed by a cable for manual remote control 8 to the length necessary to ensure well the desired angle of the hammer 5. After setting the desired angle of the hammer 5, the motor 9 is turned off, the operator pulls the cable for manual remote control 8, which pulls two small cables 14 through the rotation units 6. The force created during this (cable tension 14 and 8) leads to the release of the gripping device 4, the hammer 5 with the test product 1 falls on the anvil 7.

In this way, the required impact on the test article is realized. Personnel who are in the operating room during the test remain safe.
