Description

Technical Field

[0001] This invention relates to the field of explosives production equipment technology, and in particular to an explosives transfer device and transfer system. Background Technology

[0002] The explosives industry is one of the important industrial sectors for strengthening national defense and developing the national economy. In the military field, the explosives industry is a crucial component of the weapons industry. Explosives are the energy source for weapons; artillery shells, missiles, aerial bombs, torpedoes, mines, landmines, pyrotechnics, and blasting charges all require explosives.

[0003] During the production process of explosives, they need to be transferred between different workstations using transfer hoppers. For example...

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21 As shown, the device may include:

[0058] The hopper unit 1 includes a tooling frame 11 and a hopper assembly. The tooling frame 11 is fixedly connected to the hopper assembly. The hopper assembly includes an eccentric hopper body 12, a cover assembly 13, a pneumatic cone valve 14, and a pneumatic vibrator 15. The cover assembly 13 is hinged to the top of the eccentric hopper body 12. The pneumatic cone valve 14 is connected to the bottom of the eccentric hopper body 12. The pneumatic vibrator 15 is connected to the side wall of the eccentric hopper body 12 through a pneumatic vibrator mounting plate 16.

[0061] The tooling frame 11 and the base frame 21 are connected by floating positioning and compressed air pipeline docking through a plurality of first floating docking components 3 and a plurality of second floating docking components 4.

[0062] The explosive transfer device provided in this application embodiment can be used for automated transfer of explosives. This fixture is the first of its kind in the production of molten explosives, achieving human-machine isolation. The hopper unit 1 and the base unit 2 are connected by two sets of floating docking components, which have the functions of compressed air docking and floating docking, enabling the hopper to float and be positioned. After positioning, the air passage inside the fixture is ventilated. The floating structure design enables docking and air passage between different fixtures and different bases, eliminating the impact of manufacturing errors. The pneumatic conical valve 14 has a built-in cylinder, which can achieve automatic opening and closing. There is no friction between the powder and the opening and closing process, which is safer when used in the powder blasting process. The eccentric hopper structure and the air vibration 15 can effectively avoid arching and non-discharge during the discharging process, improving the smoothness of discharging.

[0063] To ensure that the explosives are not exposed during the transfer process, this application provides a cover assembly 13 for sealing the hopper body. Specifically, this application can provide the cover assembly 13 including a vent 131, a buckle 132, a handle 133, a quick clamp 134, and a feeding port cover 135.

[0064] Furthermore, the eccentric hopper body 12 is provided with a support block 18, a truss claw lug 19, a washer 110, a copper mesh screen 111, a support annular rib plate 112, and a hopper bottom flange 113.

The tooling frame supports the entire hopper assembly and enables conveying on the roller conveyor 5. The shock-absorbing pad 116 supports the hopper, creating a non-rigid connection between the hopper and the frame. Thus, when the air vibrator 15 on the hopper vibrates, it causes the hopper to vibrate, accelerating material discharge and preventing arching.

[0066] The pneumatic cone valve provided in this application embodiment is used to control the opening and closing of the discharge opening. Specifically, this application embodiment can provide the pneumatic cone valve including a cone rod 141, a cone cover 142, a cone ring 143, an outer sleeve 144, a cone-shaped housing 145, a mounting sleeve 146, a guide cylinder 147, a support flange 148, a sealing ring 149, a flexible connection 1410, a receiving shell 1411, a bottom ring flange 1412, a third air connector 1413, a valve body housing 1414, and an L-shaped air connector 1. 415 and adjusting shims 1416; the conical ring 143, the conical shell 145, and the supporting flange 148 are welded together; the conical rod 141 sequentially presses the conical cover 142, the conical ring 143, the outer sleeve 144, and the mounting sleeve 146 onto the guide cylinder 147; the guide cylinder 147 is used to realize the lifting and closing of the valve; the bottom ring flange 1412 has vent holes drilled inside, and air connectors are installed at both ends to connect to the guide cylinder 147 for air supply.

[0067] Furthermore, the first floating docking assembly 3 includes a first air connector 31, a first mounting base 32, a steel ball 33, a floating positioning block 34, a quick-connect female air connector 35, and a clamping sleeve 36; a cylindrical cavity is formed between the first mounting base 32 and the clamping sleeve 36, and the floating positioning block 34 can slide freely on the horizontal plane within the cylindrical cavity, forming a floating motion in the X and Y directions on the horizontal plane; the first air connector 31 and the quick-connect female air connector 35 are connected and fixedly connected to the floating positioning block 34;

[0068] The second floating docking assembly 4 includes a quick-connect male air connector 41, a guide pin 42, a second mounting base 43, and a second air connector 44; the guide pin 42 is connected to the second mounting base, and the guide pin 42 forms a through hole through both ends therethrough; the quick-connect male air connector 41 and the second air connector 44 are respectively connected to both ends of the guide pin 42.

[0069] After the first floating docking assembly 3 is connected to the second floating docking assembly 4, the quick-connect female connector 35 and the quick-connect male connector 41 of the air passage are sealed together.

[0070] Furthermore, the first floating docking assembly 3 also includes a first return spring 37, a slip ring 38, and a plurality of spherical clamping blocks 39; the first return spring 37 is fitted onto the outside of the clamping sleeve 36 and connected to the slip ring 38; the plurality of spherical clamping blocks 39 are respectively connected to the clamping sleeve 36 through hinge pins 310 and are evenly distributed along the circumferential direction of the slip ring 38; the plurality of spherical clamping blocks 39 are used to rotate along their respective hinge pins 310 to clamp the floating positioning block 34.

[0071] The second floating docking assembly 4 also includes a mounting cover 45, a sealing ring 46, and a second return spring 47; the guide pin 42 is clearance-fitted with the mounting cover 45 and the second mounting base 43, and the second return spring 47 is used to push the guide pin 42 upward so that the guide pin 42 has a vertical floating amount through the compression of the second return spring 47; the sealing ring 46 is disposed at the contact part between the guide pin 42 and the mounting cover 45.

[0072] This application embodiment can also provide a transfer system, including a transfer drive mechanism and the above-mentioned explosive transfer device.

[0073] Furthermore, the transfer drive mechanism includes any one of the following: roller conveyor 5, gantry robot 6, AGV 7, and overhead crane 8.

[0074] The structure of the explosives transfer device provided in the embodiments of this application will be described in detail below.

[0075] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the explosive transfer device includes a hopper unit 1 and a base unit 2. The hopper unit 1 includes a cover assembly 13, a hopper assembly, a tooling frame 11, a pneumatic conical valve 14, and a first floating docking assembly 3. The base unit 2 includes a second floating docking assembly 4 and an air pipe 17. The base unit 2 is used in conjunction with the hopper unit 1 to support and place the hopper unit 1. The lower half of the tooling floating docking assembly (the second floating docking assembly 4) is mounted on the base frame 21. The cover assembly 13 is fastened to the eccentric hopper body 12 by a buckle 132. The eccentric hopper body 12 is welded to the tooling frame 11. The pneumatic conical valve 14 is installed at the bottom of the eccentric hopper body 12 and connected by bolts. The first floating docking assembly 3 is bolted to the tooling frame 11.

[0076] like Figure 5 As shown, the cover assembly 13 includes: a vent 131, a latch 132, a handle 133, a quick clamp 134, and a filling port cover 135.

[0077] like Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the main body 12 of the eccentric hopper includes: a support block 18, a truss claw lug 19, a gasket 110, a copper mesh screen 111, a support annular stiffener 112, a pneumatic vibration mounting plate 16, a pneumatic vibrator 15, a bottom flange 113, and the eccentric hopper. The support block 18, truss claw lug 19, support annular stiffener 112, pneumatic vibration mounting plate 16, and bottom flange 113 are welded to the eccentric hopper.

[0078] like Figure 10 , Figure 11 As shown, the tooling frame 11 structure includes: a lifting ring 114, a welded frame, a copper pad 115, a shock-absorbing pad 116, and a positioning component mounting block 117. The tooling frame 11 provides overall support for the hopper assembly and enables conveying on the roller conveyor 5. The shock-absorbing pad 116 supports the hopper, creating a non-rigid connection between the hopper and the frame. Thus, when the air vibrator 15 on the hopper vibrates, it causes the hopper to vibrate, accelerating material feeding and preventing arching.

[0079] like Figure 12 , Figure 13 , Figure 14 As shown, the pneumatic cone valve 14 includes the following structure: cone rod 141, cone cover 142, cone ring 143, outer sleeve 144, cone housing 145, mounting sleeve 146, guide cylinder 147, support flange 148, sealing ring 149, flexible connection 1410, receiving shell 1411, bottom ring flange 1412, third air connector 1413, valve body shell 1414, L-shaped air connector 1415, and adjusting shim 1416. The cone ring 143, cone housing 145, and support flange 148 are welded together. The cone rod 141 sequentially presses the cone cover 142, cone ring 143, outer sleeve 144, and mounting sleeve 146 onto the cylinder. The guide cylinder 147 controls the valve's lifting and closing. Air holes are drilled inside the bottom ring flange 1412, and air connectors are installed at both ends to connect to the guide cylinder 147 for air supply.

[0080] The floating docking assembly includes a first floating docking assembly 3 and a second floating docking assembly 4. The purpose of this assembly is to achieve precise and airtight docking of the internal air passages, avoiding air leakage caused by machining errors. The first floating docking assembly 3 is connected to the tooling frame 11 by bolts, and the second floating docking assembly 4 is mounted on the base.

[0081] like Figure 15 , Figure 16 As shown, the first floating docking assembly 3 includes a first air connector 31, a first mounting base 32, a steel ball 33, a floating positioning block 34, a quick-connect female air connector 35, a first return spring 37, a slip ring 38, a hinge pin 310, a ball clamping block 39, and a clamping sleeve 36.

[0082] like Figure 17 , Figure 18 As shown, the second floating docking assembly 4 includes a quick-connect male air connector 41, a guide pin 42, a mounting cover 45, a sealing ring 46, a second return spring 47, a second mounting base 43, and a second air connector 44.

[0083] The first mounting base 32 and the clamping sleeve 36 are bolted to the tooling frame 11, forming a cylindrical cavity between them. The floating positioning block 34 can slide freely in the cylindrical cavity on the horizontal plane, creating a floating motion in both the X and Y directions. The first return spring 37 drives the slip ring 38 downward, which contacts the spherical surfaces of four evenly distributed spherical clamping blocks 39 along the circumference and pushes the spherical clamping blocks 39 to rotate around the hinge pin 310, thereby clamping the floating positioning block 34 and driving it to return to its original position. The guide pin 42 is clearance-fitted with the mounting cover 45 and the second mounting base 43. The second return spring 47 pushes the guide pin 42 upward, and the spring compression causes the pin to float a certain amount in the vertical direction.

[0084] like Figure 19 , Figure 20 , Figure 21 As shown, when the first floating docking assembly 3 and the second floating docking assembly 4 dock, the guide pin 42 is inserted into the floating positioning block 34, driving the floating positioning block 34 to float. At the same time, the ball clamping block 39 is pushed to rotate along the hinge pin 310, and the slip ring 38 is driven to move upward to compress the spring. The quick-connect air connector docks with the quick-connect air connector 41, and the compressed return spring causes it to float in the vertical direction, making the docking more reliable. After the quick-connect air connector 35 and the quick-connect air connector 41 dock, the external air source supplies air to the air vibrator 15 and the cylinder on the hopper in sequence from the second air connector 44—guide pin 42—quick-connect air connector 41—quick-connect air connector 35—floating positioning block 34—first air connector 31.

[0085] The working principle is as follows:

[0086] like Figure 22 , Figure 23 , Figure 24 , Figure 25 As shown, the explosive transfer device provided in this application is transferred to the base unit 2 via logistics transfer (including: roller conveyor 5, gantry robot 6, AGV7, and crane 8). The first floating docking component 3 and the second floating docking component 4 of the floating docking assembly are docked to form a connecting air passage. The air source enters the transfer fixture from the base unit 2 to realize the air supply to the cylinder and air vibration 15 in the fixture.

[0087] After ventilation, the cylinder built into the pneumatic cone valve 14 lifts the valve body to open the valve, and the cylinder descends to close the valve. After the valve is opened, the pneumatic vibrator 15 vibrates to accelerate the material feeding and prevents arching.

[0088] After the material is discharged, the cylinder descends, the pneumatic cone valve 14 closes, and the transfer tool is transferred away by logistics.

[0089] In summary, the explosives transfer device provided in this application achieves automated transfer of explosives, eliminating human intervention during material transfer and realizing human-machine isolation. The device incorporates structures such as truss claws, lifting rings, support plates, and floating docking components, making it compatible with various logistics transfer methods including roller conveyors, trusses, AGVs, and overhead cranes. This facilitates the standardization of transfer containers in automated production lines and workshops, forming a crucial foundation for unmanned production lines. The floating docking components within the device avoid the influence of processing errors between different tooling and bases, ensuring proper tooling docking and ventilation with excellent sealing. The pneumatic conical valve enables automatic opening and closing, eliminating friction with the powder and rigid compression collisions during the opening and closing process, enhancing safety during powder blasting. The eccentric hopper structure with pneumatic vibration effectively prevents arching and material blockage during feeding, improving feeding smoothness.
