Description

Technical Field

[0001] This invention relates to the field of explosive loading technology, and more specifically to an explosive loading system. Background Technology

[0002] Explosives are extremely dangerous substances that can burn and explode violently in a short period of time. They are substances that can explode due to their own energy under the influence of a certain amount of external energy. After the explosives are produced, they need to be transported by vehicles.

[0003] Explosives are typically transported in box trucks. During transport, it's crucial to minimize friction and pressure between the explosives to prevent accidents. A current invention patent (CN115709913B) discloses an explosives loading system, featuring a specially designed truck body for explosives transportation. The truck body has pallets arranged vertically, each layer supporting 2-4 layers of explosives. This allows the truck body to be relatively full, enabling full-capacity transport, improving efficiency, and reducing costs. The multi-layered pallet system also reduces pressure and friction between the explosives, minimizing risks during transport.

[0004] However, this invention patent also has corresponding problems: when stacking explosives, each pallet needs to be returned to the carriage after loading the explosives before the next pallet can be pulled out for stacking. In addition, an additional carrying platform is required to support pallets of different heights, which requires an adjustment process and affects the overall stacking efficiency. Furthermore, the separate carrying platform requires additional space. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 11 As shown, the present invention provides an explosive loading system, including a conveying device 1 for conveying explosives and a carriage 2 for mounting onto a vehicle, as well as a robotic arm for transferring explosives for stacking. The conveying device 1 is adjustable in conveying height, and the bottom of the robotic arm is provided with a lifting device for adjusting the height of the robotic arm. The top of the carriage 2 is provided with a movable structure 3 that moves along the length of the carriage 2. One end of the movable structure 3 facing away from the interior of the carriage 2 is provided with a movable support structure 4. The movable support structure 4 is provided with a stacking locking structure 5 and a transport locking structure 6. Multiple fixed support structures 7 are arranged sequentially in the vertical direction inside the carriage 2, and the movable support structure 4 is slidably connected to the fixed support structure 7. Each fixed support structure 7 is slidably connected with a pallet 8 for placing explosives. Each pallet 8 is provided with a bidirectional traction structure 9, and the two ends of the bidirectional traction structure 9 are respectively connected to the fixed support structure 7 and the movable support structure 4, and are used to pull the pallet 8 in and out of the carriage 2.

[0020] Among them, the stacking locking structure 5 is used to fix the position of the pallet 8 on the movable support structure 4 when placing explosives, and the transport locking structure 6 is used to fix the position of the pallet 8 on the fixed support structure 7 when the carriage 2 transports explosives.

[0021] In practical application, multiple pallets 8 are placed on multiple fixed support structures 7 and fixed by transport locking structure 6. At this time, multiple pallets 8 are located inside the carriage 2.

[0022] When it is necessary to load explosives, the conveying device 1 transports the explosives to the robot arm. Before that, the moving structure 3 drives the movable support structure 4 to move to the outside of the carriage 2. Then, the pallet 8 located at the lowest point inside the carriage 2 is moved to the movable support structure 4 by the bidirectional traction structure 9. The position of the pallet 8 is then fixed by the stacking locking structure 5. After that, the robot arm transfers and conveys the explosives to the pallet 8 for stacking.

[0023] After the bottom pallet 8 is loaded with explosives, the pallet 8 above it is pulled to the movable support structure 4 by the bidirectional traction structure 9. At the same time, the conveying device 1 adjusts the conveying height to match the height of the pallet 8, and the lifting device adjusts the height of the manipulator to match the height of the conveying device 1. Then the process of loading explosives is repeated until all pallets 8 are loaded with explosives.

[0024] After all the explosives have been loaded onto all the pallets 8 and pulled to the fixed support structure 7 inside the carriage 2 by the bidirectional traction structure 9, the moving structure 3 drives the movable support structure 4 to move into the carriage 2 and restricts the movement of the movable support structure 4 inside the carriage 2 by the moving structure 3. Then, the multiple pallets 8 are fixed by the transport locking structure 6 to ensure the stability of the pallets 8 during the transport process.

[0025] During the loading of explosives, multiple pallets 8 are loaded with explosives sequentially from bottom to top. It is not necessary to wait for the pallets 8 loaded with explosives to move into the carriage 2 before loading explosives. The upper pallets 8 can be moved directly to the movable support structure 4 to load explosives, which improves the efficiency of explosive loading.

[0026] In this embodiment, the conveying device 1, the robot arm, and the lifting device are all existing technologies. The conveying device 1 and the robot arm can refer to the conveying system and palletizing robot arm in the invention patent with publication number CN115709913B. The lifting device can be a hydraulic push rod with a mounting plate on it, and the robot arm can be mounted on the mounting plate, or other technical solutions are also possible. The technical principles will not be elaborated in detail here.

[0027] The movable structure 3 includes a movable seat 301 and two sliding seats 304 located on the top of the carriage 2. The two sliding seats 304 are fixedly connected to the carriage 2. An adjusting screw 302 is rotatably mounted on the movable seat 301. One end of the adjusting screw 302 is connected to a drive mechanism. An isolation cover connected to the movable seat 301 is provided outside the drive mechanism. A connecting plate 303 that is slidably connected to the movable seat 301 is threaded onto the adjusting screw 302. Multiple sliding plates 305 are evenly spaced on both sides of the connecting plate 303. A groove 306 is opened on one end of the two sliding seats 304 facing the exit of the carriage 2, and the multiple sliding plates 305 are slidably connected in the two grooves 306 respectively.

[0028] The drive mechanism drives the adjusting screw 302 to rotate, thereby driving the connecting plate 303 to move, so that the connecting plate 303 can drive the movable support structure 4 to enter and exit the carriage 2.

[0029] The connection between multiple sliding plates 305 and the sliding grooves 306 on the sliding seat 304 improves the stability of the connecting plate 303 during movement, and there is a large space between two adjacent sliding plates 305 to avoid interference with the loading of explosives.

[0030] By setting up an isolation cover to isolate the drive mechanism, the drive mechanism can be prevented from affecting the safety of the explosives inside.

[0031] Furthermore, in this embodiment, the drive mechanism may use an explosion-proof motor.

[0032] The movable support structure 4 includes a support plate 401 vertically disposed at the bottom of the connecting plate 303. A movable plate 402 is rotatably connected to the bottom of the support plate 401. A fixed plate 403 is disposed on one side of the movable plate 402 and is fixed to the support plate 401 by a limiting pin. The movable plate 402 is controlled by inserting and removing the limiting pin. Multiple extension plate groups are disposed at equal intervals along the vertical direction on one side of the support plate 401. Each extension plate group includes multiple extension plates 404 connected to the support plate 401, and the multiple extension plates 404 are slidably connected within the fixed support structure 7.

[0033] The connecting plate 303 drives the support plate 401 to move outside the carriage 2. The movable plate 402 separates from the carriage 2 and rotates downward to be parallel to the support plate 401. The fixed plate 403 is fixed to the support plate 401 by the limiting pin, thereby restricting the rotation of the movable plate 402. This allows the movable plate 402 and the support plate 401 to jointly support multiple extension plates 404, thereby enabling the multiple extension plates 404 to stably bear the support plate 8.

[0034] After the pallet 8 is loaded, remove the limit pin and rotate the movable plate 402 to a horizontal state. After the support plate 401 moves into the carriage 2 along with the connecting plate 303, the movable plate 402 contacts the inner bottom of the carriage 2 and slides along the inner bottom of the carriage 2 into the carriage 2.

[0035] The palletizing locking structure 5 includes locking blocks 501 respectively disposed on multiple extension plate groups, and each locking block 501 is disposed on one of the extension plates 404 in each extension plate group. Each pallet 8 has a locking groove 507 at its bottom. Each of the multiple extension plates 404 with locking blocks 501 has a limiting groove 508. Each limiting groove 508 is provided with a spring 509 connected to the locking block 501. Each locking block 501 has an extension rod 502 connected to its bottom. Each extension rod 502 has a control rod 503 perpendicular to the support plate 401 at its bottom. Each control rod 503 extends to the side of the support plate 401 away from the interior of the carriage 2. The ends of the multiple control rods 503 are connected to a synchronization plate 504. The support plate 401 is provided with a first telescopic device 505 connected to the synchronization plate 504. The first telescopic device 505 moves in the vertical direction.

[0036] The pallet 8 moves to the corresponding multiple extension plates 404 through the bidirectional traction structure 9, so that the multiple extension plates 404 of the extension plate group jointly support the pallet 8. The pallet 8 moves to contact the locking block 501 and squeezes the locking block 501 into the limiting groove 508 and squeezes the spring 509. As the pallet 8 continues to move, the locking block 501 enters the locking groove 507 on the pallet 8 under the action of the elastic force of the spring 509, thereby restricting the movement of the pallet 8 on the extension plate 404.

[0037] When it is necessary to release the restriction on the pallet 8, the first telescopic device 505 drives the synchronous plate 504 to move downward. The synchronous plate 504 drives multiple control rods 503 to move downward synchronously, and multiple extension rods 502 also move downward synchronously. This causes multiple locking blocks 501 to move in the synchronous limiting grooves 508 and squeeze the springs 509 until the locking blocks 501 disengage from the corresponding locking grooves 507. At this time, the pallet 8 can enter and exit the carriage 2 by the traction of the bidirectional traction structure 9.

[0038] The transport locking structure 6 includes a second telescopic device 601 mounted on the side wall of the support plate 401 facing the interior of the carriage 2 and moving vertically. The output end of the second telescopic device 601 is provided with a vertical plate 602 that is slidably connected to the outer wall of the support plate 401 perpendicular to the exit of the carriage 2. The vertical plate 602 is provided with a plurality of wedge blocks 603 that are slidably connected to the support plate 401, and the number of wedge blocks 603 is the same as the number of pallets 8.

[0039] When all pallets 8 are located on multiple fixed support structures 7 inside the carriage 2, and the movable support structure 4 is also located inside the carriage 2, with the movable support structure 4 fixed in position by the moving structure 3, the second telescopic device 601 drives the vertical plate 602 to move downward, thereby causing multiple wedge blocks 603 to move synchronously, so that the wedge blocks 603 insert into the gap between the support plate 401 and the pallet 8, thereby squeezing the pallet 8 to move away from the support plate 401 to the limit position and stop, thus fixing the position of the pallet 8 and ensuring the stability of the explosives on the pallet 8 during transportation.

[0040] In this embodiment, the horizontal cross-section of the support plate 401 is square. Among the multiple outer walls of the support plate 401 that are perpendicular to the horizontal plane, there is an outer wall facing the inside of the carriage 2 and an outer wall facing the outside of the carriage 2. The vertical plate 602 is set on the outer wall between these two outer walls to avoid interference with the support plate 8.

[0041] In this embodiment, both the first telescopic device 505 and the second telescopic device 601 are existing technologies, such as hydraulic push rods.

[0042] The fixed support structure 7 includes two parallel side connecting seats 701 respectively set on two opposite side walls inside the carriage 2. Multiple base plates 702 are fixedly connected to the two side connecting seats 701. The multiple base plates 702 are provided with slide rails for mounting the tray 8. Multiple moving grooves 703 are opened along their own length direction on the multiple base plates 702, and each extension plate 404 is slidably connected in the corresponding moving groove 703.

[0043] Two side connecting seats 701, multiple base plates 702 and slide rails jointly support the pallet 8. Multiple moving slots 703 are used to install extension plates 404, so that when the extension plates 404 are inside the carriage 2, they will not lift the pallet 8, ensuring the normal movement of the pallet 8 on the slide rail. When the extension plates 404 are outside the carriage 2, they can normally support the pallet 8.

[0044] In this embodiment, the slide rail is existing technology, and its principle will not be explained in detail. The bottom of the slide rail on each fixed support structure 7 is at the same height as the upper surface of the corresponding extension plate group.

[0045] The bidirectional traction structure 9 includes two traction cables 901 connected to both sides of the support plate 8 respectively. The support plate 8 has a sliding cavity 902 inside. Two sliders 903 connected to the two traction cables 901 are slidably connected in the sliding cavity 902. An elastic rope 904 is connected to the opposite sidewalls of the two sliders 903. A winding roller 905 is connected to the end of each traction cable 901 away from the slider 903. One winding roller 905 is set on the support plate 401, and the other winding roller 905 is set on one of the base plates 702.

[0046] When the traction pallet 8 moves, the corresponding take-up roller 905 is driven by a drive device such as an explosion-proof motor, so that the traction cable 901 on the corresponding side of the pallet 8 pulls the corresponding slider 903 to move in the sliding cavity 902 until the slider 903 abuts against the inner wall of the sliding cavity 902. Then the pallet 8 moves with the slider 903 until the pallet 8 reaches the designated position.

[0047] While one slider 903 is moving, the other slider 903 also moves under the traction of the elastic rope 904, which in turn pulls the corresponding traction cable 901 to be released from the other take-up roller 905, so as to ensure that the pallet 8 can move normally. By setting the elastic rope 904, the two traction cables 901 can be kept taut and have a certain buffer space to avoid the other take-up roller 905 being directly pulled and damaged when one take-up roller 905 is suddenly started.

[0048] Both ends of the sliding cavity 902 are provided with connection ports that communicate with the outside of the support plate 8, and the diameter of the connection port is larger than the diameter of the traction cable 901. Multiple balls for contacting the traction cable 901 are evenly arranged on the inner wall of the connection port.

[0049] The friction between the traction cable 901 and the connection port is reduced, thereby reducing the generation of static electricity. At the same time, ball bearings are installed to prevent the traction cable 901 and the connection port from sliding and rubbing against each other, further reducing the generation of static electricity.

[0050] In this embodiment, both the traction cable 901 and the elastic rope 904 are made of antistatic materials.

[0051] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
