Description

Technical Field

[0001] The utility model relates to the technical field of head and tail board assembly, in particular to a vehicle body structure used for assembling head and tail boards. Background Art

[0002] Head and tail plates refer to the plates located at both ends of the coil during the steel production process, especially in the production of stainless steel coils. After the head and tail plates are produced and processed, they need to be assembled to the two ends of the coil, which requires the assistance of an assembly vehicle. For example, a hand-push forklift is needed to lift and move the head and tail plates during assembly. A hand-push forklift is a lightweight material handling equipment, mainly used for short-distance transportation and stacking of goods in factories, warehouses, logistics centers and other places. When a hand-push forklift is used to lift the head and tail plates, it is moved upward through the output end of the hydraulic cylinder, and then the chain hinged at the output end of the hydraulic cylinder is used to pull the fork teeth to move upward.

[0003] After using a hand-push forklift to lift the head and tail plates many times, the chain used to pull the fork teeth on it often wears out and needs to be replaced. When replacing the chain, the bolts fixing the chain need to be removed. Because the hand-push forklift is used in a factory, its complex bolts often rust due to long-term contact with dust and oil in the factory, making it inconvenient for workers to remove it.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1-4The utility model provides an embodiment: a vehicle body structure for assembling a head and tail plate, including a frame 1, a fixing plate 3 is arranged on one side of the frame 1, and there is no connection between the frame 1 and the fixing plate 3, a reinforcing rod 9 is fixedly connected to the middle part of the other side of the frame 1, cavities 23 are provided on the front and rear sides of the top of the reinforcing rod 9, mounting blocks 20 are slidably connected inside the two cavities 23, mounting grooves 24 are provided on both sides of the two mounting blocks 20, a plurality of springs 22 are fixedly connected inside the plurality of mounting grooves 24, a plurality of springs 22 are fixedly connected at the other ends thereof with protrusions 21, and the other ends of the plurality of protrusions 21 respectively penetrate the two sides of the inner wall of the cavity 23, a chain 11 is fixedly connected to the top of the two mounting blocks 20, and the other ends of the two chains 11 are fixedly connected to the plug blocks 14 respectively, and the two plug Fixed grooves 13 are provided at both ends of the top and bottom of both sides of the block 14, slots 16 are provided on both sides of the front and rear sides of the top of the fixing plate 3, grooves 19 are provided on both sides of the top and bottom of the inner walls of the multiple slots 16, and fixed blocks 18 are slidably connected inside the multiple grooves 19, and one end of the multiple fixed blocks 18 is fixedly connected to the pull rod 17, and the other ends of the multiple fixed blocks 18 are slidably connected inside the fixed groove 13. The two plug-in blocks 14 are slidably connected inside the slot 16. When the chain 11 needs to be replaced, the protrusion 21 can be pressed to retract the spring 22, and the mounting block 20 can be pulled up to remove the mounting block 20 from the cavity 23, and then the pull rod 17 is pulled to make the fixed block 18 withdraw from the fixed groove 13, and the plug-in block 14 is taken out from the slot 16 to disassemble and replace the chain 11.

[0036] When the new chain 11 needs to be fixed, the mounting block 20 can be extended into the cavity 23, and the protrusion 21 can be pushed by the spring 22 to move and penetrate the inner wall of the cavity 23, thereby fixing one end of the chain 11, and then the insert block 14 is extended into the slot 16 and the push rod 17 makes the fixing block 18 enter the fixing groove 13 to fix the other end of the chain 11.

[0037] The end of the protrusion 21 away from the spring 22 is set to be arc-shaped. When the mounting block 20 slides inside the cavity 23, the inner wall of the cavity 23 will squeeze the protrusion 21, thereby forcing the protrusion 21 to retract into the mounting groove 24. When the protrusion 21 penetrates the inner wall of the cavity 23, the arc surface part of the protrusion 21 will completely extend out of the inner wall of the cavity 23.

[0038] Springs 15 are respectively wrapped around the outside of the multiple pull rods 17, one end of the multiple springs 15 is fixedly connected to one side of the fixed block 18, and the other end of the multiple springs 15 is fixedly connected to the inner wall of the groove 19. The springs 15 can be used to push the fixed block 18 into the fixed groove 13, thereby fixing the plug block 14.

[0039] The bottom wall of the frame 1 is fixedly connected with a hydraulic cylinder 5, and the driving end of the hydraulic cylinder 5 is fixedly connected with a connecting rod 10. Both ends of the connecting rod 10 are rotatably connected with gears 12, and the two gears 12 are respectively meshed and connected to the bottom ends of the chains 11. The rising of the driving end of the hydraulic cylinder 5 drives the connecting rod 10 to move, and when the connecting rod 10 rises, the chain 11 can pull the fixed plate 3 to move upward.

[0040] The frame 1 is provided with slots 2 on both the front and rear sides, and rollers 6 are slidably connected inside the two slots 2. The two rollers 6 are rotatably connected to the two sides of the fixed plate 3 on the sides away from each other. The bottom end of the fixed plate 3 is fixedly connected with fork teeth 4. When the fixed plate 3 rises, the rollers 6 will slide inside the slots 2, and the fixed plate 3 can be fixed by sliding the rollers 6.

[0041] Universal wheels 7 are fixedly connected to both sides of the bottom of the frame 1. An extension rod is provided on one side of the bottom of the frame 1 close to the fixed plate 3, and a wheel is fixed to the bottom of the extension rod. The universal wheels 7 can be used to move the frame 1 on the ground.

[0042] A handle 8 is rotatably connected to the rear side of the bottom end of the frame 1. Pulling the handle 8 can rotate the universal wheel 7 so that the frame 1 can move on the ground.

[0043] An insertion rod 25 passes through the inside of the two cavities 23, and the outer side of the middle part of the two insertion rods 25 passes through the inside of the mounting block 20. After the mounting block 20 is fixed to the inside of the cavity 23, the insertion rod 25 can be extended into the inside of the cavity 23 and pass through the inside of the mounting block 20 and extend out from the other side of the cavity 23, thereby assisting the protrusion 21 to fix the mounting block 20.

[0044] Working principle: when it is necessary to move the material, the fork teeth 4 can be extended into the material, and then the rising of the driving end of the hydraulic cylinder 5 can be used to drive the connecting rod 10 to move. When the connecting rod 10 rises, the chain 11 can pull the fixed plate 3 to move upward, and the fixed plate 3 can be used to drive the fork teeth 4 to move upward to lift the material. When the fixed plate 3 moves, the roller 6 will slide inside the slot 2, and the fixed plate 3 of the sliding roller 6 can be limited so that the fixed plate 3 can be close to the frame 1. Then, the handle 8 can be pulled to rotate the universal wheel 7 under the frame 1 so that the frame 1 can move on the ground. When the chain 11 needs to be replaced, the protrusion 21 can be pressed to retract the spring 22, and the mounting block 20 can be pulled up to remove the mounting block 20 from the cavity 23. Then, the pull rod 17 can be pulled to make the fixed block 18 withdraw from the fixed slot 13, and the plug block 14 can be taken out from the slot 16 to disassemble and replace the chain 11.
