A shell disassembly production line

Abstract

The present invention relates to the technical field of dismantling and destroying dangerous goods, and in particular to a shell dismantling production line. The shell dismantling production line disclosed by the present invention comprises an accumulation-type hanging conveyor chain and a U-shaped water tank. The accumulation-type hanging conveyor chain is arranged above the U-shaped water tank. The U-shaped water tank comprises two parallel parts and a connecting part connecting the two parallel parts. The bottom surfaces of the two parallel parts of the U-shaped water tank are inclined toward the connecting part. The U-shaped water tank is filled with a high-temperature liquid that can carry out explosives. The accumulation-type hanging conveyor chain drives the shells to pass through the U-shaped water tank below the liquid level of the high-temperature liquid, so that the explosives inside the ammunition can be suspended and deposited in the high-temperature liquid.

This can not only avoid the problem of easy explosion of the shells in the past when the explosives are directly disassembled by humans, but also significantly reduce the workload.

Description

Technical Field

[0001] The invention relates to the technical field of dismantling and destroying dangerous goods, and in particular to a shell dismantling production line. Background Art

[0002] As one of the important weapons in modern warfare, artillery shells play an important role on the battlefield. With the development of science and technology, the development and application of new artillery shells have gradually accelerated, and the replacement speed of artillery shells has also accelerated, resulting in a lot of waste artillery shells. These artillery shells can no longer meet the requirements of modern warfare. In order to reduce safety hazards, they need to be forcibly scrapped as soon as possible.

[0003] Traditional methods of forced scrapping are mostly manual disassembly with mechanical assistance. This type of disassembly method is not only inefficient, but also poses a major safety hazard. The dismantled gunpowder may cause a major accident if not handled with care, threatening the lives of the shell dismantling personnel. Summary of the invention

[0004] The purpose of the present invention is to provide a shell disassembly production line to improve the safety and efficiency of explosive disassembly during shell disassembly and reduce the work intensity of disassembly personnel.

[0005] To achieve the above-mentioned purpose, the present invention provides a shell disassembly production line, including an accumulation-type hanging conveyor chain and a U-shaped water trough, wherein the accumulation-type hanging conveyor chain is arranged above the U-shaped water trough, and a plurality of conveying frames for independently conveying shells are arranged under the accumulation-type hanging conveyor chain, and a bullet nose clamp and a bullet tail clamp are arranged at the bottom of the conveying frame, and the conveying frame clamps the shell body through the bullet nose clamp and the bullet tail clamp, and the U-shaped water trough includes two parallel parts and a connecting part connecting the two parallel parts, and the bottom surfaces of the two parallel parts of the U-shaped water trough are inclined toward the connecting part.

[0006] The present invention aims at the problems of insufficient disassembly efficiency and safety in the process of disassembling shells. The present invention uses the accumulation type suspension conveyor chain to transport shells. The U-shaped water tank is filled with high-temperature liquid that can take out explosives. The explosives in the opened shells are separated from the shells by filling the U-shaped water tank with high-temperature liquid. Compared with the traditional manual disassembly of shells, the present invention uses high-temperature liquid to take away the explosives inside the shells, which can significantly improve the disassembly efficiency of the shells. On the other hand, the bottom surface height of the two parallel parts of the U-shaped water tank is higher than the connecting part, so that the explosive particles are automatically concentrated to the connecting part under the action of gravity, which is convenient for the subsequent processing of the explosive particles. At the same time, the use of automated equipment reduces human participation process, the accumulation-release type suspension chain is used to drive the conveying frame to circulate at each workstation along the production line, the bullet head clamp and the bullet tail clamp are arranged at the bottom of the conveying frame, and the shell body is always below the liquid level in the U-shaped water tank, so as to facilitate the removal of the explosive inside the shell body. It should be noted that the accumulation-release type suspension conveying chain in this case includes components such as conveying rails, traction chains and tensioning devices, which can realize the conveying or stopping of accumulation of the conveying frame by controlling the engagement and disengagement between the conveying frame and the traction chain. Because it belongs to the prior art, its structure is not described in detail in this application.

[0007] Furthermore, the disassembly production line also includes an automatic grooving machine, an extrusion machine, a hot air device and an explosion-proof electric heater. Along the flow direction of the accumulation type suspension conveyor chain, the automatic grooving machine is arranged on one side of the accumulation type suspension conveyor chain, the extrusion machine and the U-shaped water trough are flexibly coordinated to squeeze out the shells after grooving, the hot air device is arranged at the tail end of the accumulation type suspension conveyor chain, and the explosion-proof electric heater is arranged in the U-shaped water trough.

[0008] The automatic grooving machine is used to groove the shells. In the disassembly production line of the present invention, manual unpacking is used, and the shells are put into the automatic grooving machine with the help of the power-assisted manipulator to carry out the grooving work. The extrusion machine is used to cooperate with the accumulation-type hanging conveyor chain to extrude and break the shells sent to the extrusion and breaking station. The shells are also transported between the automatic grooving machine and the extrusion machine by the help-assisted manipulator. The hot air device is arranged at the end of the accumulation-type hanging conveyor chain. When the shells are left standing for a period of time and the medicine is added, they can be sent to the hot air device with the accumulation-type hanging chain for hot air drying. The explosion-proof electric heater is used to heat the liquid and keep it at a constant temperature. The high-temperature liquid can be water or other organic solvents that can dissolve explosives. The power-assisted manipulator adopts a pneumatic balance assistant to reduce the labor intensity of the operator.

[0009] Furthermore, the U-shaped water tank includes a water tank frame, a tank body and a heat insulation box. The tank body is installed on the water tank frame, and the tank body is a sandwich structure. The sandwich is filled with foamed polyurethane as an insulation layer. The heat insulation box covers the top of the tank body.

[0010] The water tank rack is used to place the trough body, and the bottom of the trough body has a certain inclination, and the inclination angle ranges from 1° to 30°, preferably 1° to 3°. Along the extension of the trough body, the inclination reaches the lowest position at the connection part of the trough body. The heat insulation box is arranged above the trough body to seal the trough body to reduce the risk of splashing and injuring people from the high-temperature liquid inside the trough body. Foamed polyurethane is arranged in the interlayer as an insulation layer to reduce the heat loss of the liquid inside the trough body. It should be noted that the U-shaped water tank can also be set to a strip shape as needed, and it only needs to be that the bottom surface of one end is higher than the bottom surface of the other end, so that the explosives separated from the shells can be automatically gathered under the action of gravity.

[0011] Furthermore, a flow channel cooperating with the conveying frame is reserved in the upper middle portion of the heat insulation box, and a sealing plate is also provided on the outer side of the heat insulation box. The sealing plates are relatively arranged on both sides of the outside of the heat insulation box to form a closure outside the heat insulation box and the accumulation type suspension conveying chain. A flexible material is also provided at the contact portion between the flow channel and the conveying frame to close the flow channel.

[0012] The flow channel is arranged in the same direction as the U-shaped water trough to cooperate with the flow of the accumulation-type hanging conveyor chain. At the same time, a flexible material is arranged along the inner wall of the flow channel to automatically close the flow channel by utilizing the reset ability of the flexible material when the conveying frame does not enter. The sealing plate is arranged on the outside of the heat insulation box and the accumulation-type hanging conveyor chain to further close the entire conveying process, enhance the isolation between the inside and the outside, and reduce the overflow of internal high-temperature hot water or hot steam to injure people and the intrusion of external impurities.

[0013] Furthermore, the extrusion machine includes a U-shaped seat body, a clamping block and an extrusion block. The U-shaped seat body is installed on the water tank frame and covers the outer side of the tank body. The clamping blocks are arranged in pairs on one side of the tank body and are externally connected to a clamping hydraulic cylinder. The clamping blocks are movably matched with the tank body. The extrusion block is arranged on the other side of the tank body and is externally connected to an extrusion hydraulic cylinder. The extrusion block is movably matched with the tank body.

[0014] The U-shaped seat is arranged at the lower side of the trough body to accommodate the clamping hydraulic cylinder and the extrusion hydraulic cylinder. The clamping pressure block and the extrusion pressure block are distributed on both sides of the interior of the trough body and are offset, so that the extrusion work can be performed after the shell enters the extrusion station.

[0015] Furthermore, the automatic grooving machine is a horizontal lathe structure, and a tool holder, a variable frequency motor and a pneumatic chuck fixture are arranged on the bed. The variable frequency motor is placed on the edge of the bed as a power source, and the tool holder is placed on the surface of the bed to cut a groove on the outer edge of the shell. The pneumatic chuck fixture is set on the bed to clamp the shell placed in the specified position.

[0016] The automatic grooving machine is used to make grooves on the periphery of the shell, and the groove depth can be adjusted according to the thickness of the shell body. After the shell enters the specified position of the pneumatic chuck fixture, the pneumatic chuck fixture automatically clamps the shell and fixes it, and the tool holder performs the grooving work. The tool holder is also equipped with movable water retaining and chip covers. The movable water retaining and chip covers are removed during loading and unloading to facilitate loading and unloading. During operation, installing the movable water retaining and chip covers can effectively prevent cooling water and chips from splashing, thereby improving the working environment of this workstation.

[0017] Furthermore, the hot air device includes a box body, a hot air pipe and a hot air blower. The box body is arranged outside the U-shaped water tank, the hot air blower is externally placed and connected to the box body through the hot air pipe, and the box body is also provided with an exhaust port, which is externally connected to the workshop exhaust equipment.

[0018] The box cooperates with the external hot air blower to obtain hot air through the hot air pipe to dry the shells that have been squeezed and charged.

[0019] Furthermore, the shell disassembly production line also includes a discharge device, and the discharge device is arranged at the connection part of the U-shaped water tank.

[0020] The discharge device is used to discharge the explosives deposited in the U-shaped water tank. After the explosives are accumulated at the bottom of the U-shaped water tank, the explosives are discharged from the U-shaped water tank through the discharge device.

[0021] Furthermore, the discharging device includes an inlet valve, a discharge valve and a drain valve. One end of the inlet valve is connected to the U-shaped water tank, and the other end is connected to an external water pump group. One end of the discharge valve is connected to the U-shaped water tank, and the other end is connected to the explosive collection barrel through a discharge hose. One end of the drain valve is connected to the U-shaped water tank, and the other end is connected to the discharge pool through a drain hose.

[0022] The water inlet valve is externally connected to a water pump group to deliver liquid to the U-shaped water tank, and the height of the discharge valve is lower than that of the drain valve. After the disassembly is completed and the deposited explosives are post-processed, the explosives will be deposited at the bottom of the tank due to their high density. The drain valve can drain the liquid into the discharge water tank, and the discharge valve can discharge the explosives mixed with the liquid into the explosive collection barrel until the predetermined weight is reached after the drain valve completes the drainage.

[0023] Furthermore, the shell disassembly production line also includes a lifting device, which is arranged on one side of the discharge pool. The lifting device includes a lifting cylinder, a lifting frame, a lifting frame, a U-shaped clamp block, a clamp block pushing bracket, a rodless cylinder, a lifting guide rail, a protective cover and a manual air valve. The manual air valve can respectively control the horizontal and vertical movement of the lifting frame and the tensioning of the U-shaped clamp block. The manual air valve is used to control the U-shaped clamp block to clamp the explosive collection barrel filled with a set weight, and then control the lifting frame to lift up to a predetermined height, and place it at a designated position after translation.

[0024] The lifting device is used to transport the explosive collection barrel. After the explosive collection barrel completes collection, the manual air valve can be used to control the U-shaped clamp to clamp the explosive collection barrel, and then the lifting cylinder and the lifting frame cooperate to complete the transportation of the explosive collection barrel.

[0025] Furthermore, the shell disassembly production line also includes two lifting work platforms, which are respectively arranged at the loading station and the unloading station of the accumulation type suspension conveyor chain, and the lifting work platform includes a rubber baffle, a work table, a guide column, a cylinder mounting plate and a cylinder. The work table is lifted and lowered by the cylinder, the rubber baffle is arranged on the outer edge of the work table, the guide column is arranged on the corner of the work table, and the output end of the cylinder is connected to the work table through the cylinder mounting plate.

[0026] The height of the work surface can be adjusted and raised by the cylinder, so as to facilitate the lifting of the shell, and facilitate the workers to remove the shell and the shell clamp, and when loading, the shell to be processed is raised to facilitate the clamping of the conveying frame.

[0027] The shell disassembly production line of the present invention is based on the existing technology. In view of the problem that the current shell disassembly production line requires human participation and there is a risk of explosion if the unloaded explosives are not handled carefully, the method of disassembling the shells and explosives is improved. After the shells are cut into grooves, squeezed and cut, the explosives in the shells can be taken out below the liquid level of a U-shaped water tank, which significantly improves the safety of disassembling the explosives, reduces the workload of personnel, and avoids the occurrence of safety accidents.
