Abstract
Description
Technical Field
[0001] The utility model relates to a protective device for strengthening a transport vehicle against gravity deformation, belonging to the technical field of transport vehicles. Background Art
[0002] A pallet truck is a logistics handling equipment used to transport goods. When a manual pallet truck is used at a handling station, the forks it carries are inserted into the holes in the pallet. The hydraulic system is driven by manpower to lift and lower the goods on the pallet, and the handling operation is completed by manpower pulling. It is the simplest, most effective and most common loading and unloading and handling tool among the pallet transport tools at the handling station.
[0003] However, when a truck is transporting goods, if the goods themselves are heavy, the goods may bounce up and down in the truck when passing through bumpy roads. The greater the weight of the goods, the greater the impact generated when moving. When the goods hit the inside of the truck, the truck may be deformed due to the impact of the goods, which may cause damage to the truck.
[0004] Therefore, a protective device for strengthening a transport vehicle against gravity deformation is proposed. Utility Model Content
[0005] In view of this, the utility model provides a device for strengthening the anti-gravity deformation protection of a transport vehicle to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.
[0006] The technical solution of the utility model is achieved as follows: a device for strengthening the anti-gravity deformation protection of a transport vehicle comprises a vehicle body, a mounting frame is fixedly installed on the top of the vehicle body, a cylinder is fixedly installed on the top of the mounting frame, a support plate is arranged in the inner cavity of the vehicle body, moving wheels are movably connected to the front and rear sides of the vehicle body, auxiliary wheels are movably connected to the left and right sides of the bottom of the vehicle body, a buffer mechanism is arranged at the bottom of the inner cavity of the vehicle body, the buffer mechanism comprises a fixed frame, a sliding rod, a sliding block, a hexagonal frame, a hard spring, a connecting plate, a hydraulic pipe, an inner rod, a circular plate and an oil valve, and the fixed frame is fixedly installed at the bottom of the inner cavity of the vehicle body.

[0008] Further preferably, movable grooves are provided around the top of the fixing frame, and the bottoms of the six sliding blocks are slidably connected to the inner cavities of the six movable grooves.
[0009] Further preferably, the hydraulic pipe is fixedly installed at the bottom of the inner cavity of the hexagonal frame, the inner rod is movably connected in the inner cavity of the hydraulic pipe, the circular plate is fixedly installed at the top of the inner rod, and the oil valve is fixedly installed on the right side of the hydraulic pipe.
[0010] Further preferably, a fixing mechanism is provided at the bottom of the cylinder, and the fixing mechanism includes a frame, the frame is fixedly installed on the bottom of the cylinder, a mounting plate is fixedly installed on the inner side of the frame, a motor is fixedly installed on the top of the mounting plate, the output end of the motor is fixedly connected to a gear, tooth plates are provided on the front and rear sides of the gear, the inner sides of the two tooth plates are meshed with the outer sides of the gear, connecting rods are fixedly installed on the bottom of the two tooth plates, and splints are fixedly installed on the bottom of the two connecting rods.
[0011] Further preferably, sliding rods are fixedly installed on both the front and rear sides of the inner side of the frame, and the two tooth plates are slidably connected to the surfaces of the two sliding rods.
[0012] Further preferably, movable grooves are provided on both the front and rear sides of the bottom of the inner cavity of the frame, and the two connecting rods pass through the inner cavities of the two movable grooves and extend to the bottom of the frame.
[0013] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:
[0014] 1. The utility model provides a buffer mechanism. When the goods bump up and down, the connecting plate flips inward and pushes the slider to move inward. As the slider moves, the hard spring is deformed due to the action of force, and the tension of the hard spring itself buffers the pressure of the goods when they go down, thereby achieving a shock-absorbing and buffering effect on the goods. This effectively avoids the situation where the goods bump up and down synchronously with the vehicle when the vehicle moves up and down over a bumpy road, which causes the goods to hit the bottom of the vehicle body due to the impact force generated by the bump, causing the vehicle body to be deformed and damaged due to the impact force of the goods hitting the vehicle.
[0015] Second, the utility model can convert the downward pressure of the goods into an inward extrusion force by setting a connecting plate, and buffer the extrusion force through the tension of the hard spring itself. By setting a movable groove, the moving direction of the slider can be limited to avoid the slider from deflecting when moving, thereby affecting the buffering work of the goods. By setting a hydraulic pipe, an inner rod, a circular plate and an oil valve, when the goods drive the pallet to press the circular plate downward to move, the inner rod moves downward synchronously, and the hydraulic oil in the inner cavity of the hydraulic pipe buffers the downward pressure of the inner rod, thereby realizing the shock absorption and buffering work of the goods. By setting a fixing mechanism, the position of the goods can be fixed to avoid the goods from moving in the left and right directions when passing through a bumpy road section, causing the inner wall of the vehicle body to be deformed due to the impact force of the goods. By setting a sliding rod, the tooth plate can be guided to avoid the left and right directions when it moves, and then the problem of being unable to fix the goods occurs. By setting a movable groove, the moving direction of the connecting rod can be limited to avoid the connecting rod from deflecting when moving, causing the moving direction of the splint to change synchronously, so that the goods cannot be fixed.

DETAILED DESCRIPTION
[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.
[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0028] Example 1
[0029] like Figure 1-7 As shown, an embodiment of the utility model provides a device for strengthening the anti-gravity deformation protection of a transport vehicle, including a vehicle body 1, a mounting frame 6 is fixedly installed on the top of the vehicle body 1, a cylinder 7 is fixedly installed on the top of the mounting frame 6, a support plate 8 is arranged in the inner cavity of the vehicle body 1, moving wheels 4 are movably connected to the front and rear sides of the vehicle body 1, auxiliary wheels 5 are movably connected to the left and right sides of the bottom of the vehicle body 1, a buffer mechanism 2 is arranged at the bottom of the inner cavity of the vehicle body 1, the buffer mechanism 2 includes a fixed frame 201, a sliding rod 202, a sliding block 203, a hexagonal frame 204, a hard spring 205, a connecting plate 206, a hydraulic pipe 208, an inner rod 209, a circular plate 210 and an oil valve 211, and the fixed frame 201 is fixedly installed at the bottom of the inner cavity of the vehicle body 1.
[0030] By setting up the buffer mechanism 2, when the goods bump up and down, the connecting plate 206 flips inward and pushes the slider 203 to move inward. As the slider 203 moves, the hard spring 205 is deformed due to the action of the force, and the tension of the hard spring 205 itself buffers the pressure of the goods when they move downward, thereby achieving a shock-absorbing and buffering effect on the goods, and effectively preventing the goods from bumping up and down synchronously with the vehicle when the vehicle moves up and down through a bumpy road section, thereby causing the goods to hit the bottom of the vehicle body 1 due to the impact force generated by the bump, causing the vehicle body 1 to be deformed and damaged due to the impact force of the goods hitting the vehicle body 1.
[0031] Example 2
[0032] In one embodiment, the six sliding bars 202 are all fixedly installed on the inner side of the vehicle body 1, the six sliders 203 are all slidably connected to the surfaces of the six sliding bars 202, the six frames 204 are fixedly installed on the top of the fixed frame 201, the six hard springs 205 are all fixedly connected to the inner sides of the six sliders 203, the inner sides of the six hard springs 205 are all fixedly installed on the outer sides of the six frames 204, the six connecting plates 206 are all movably connected to the tops of the six sliders 203, the tops of the six connecting plates 206 are movably connected to the bottom of the support plate 8, movable grooves 207 are opened around the top of the fixed frame 201, the bottoms of the six sliders 203 are all slidably connected to the inner cavities of the six movable grooves 207, the hydraulic pipe 208 is fixedly installed at the bottom of the inner cavity of the six frames 204, the inner rod 209 is movably connected to the inner cavity of the hydraulic pipe 208, the circular plate 210 is fixedly installed on the top of the inner rod 209, and the oil valve 211 is fixedly installed on the inner cavity of the hydraulic pipe 208. On the right side, a fixing mechanism 3 is provided at the bottom of the cylinder 7, and the fixing mechanism 3 includes a frame 301, which is fixedly installed on the bottom of the cylinder 7, a mounting plate 302 is fixedly installed on the inner side of the frame 301, a motor 303 is fixedly installed on the top of the mounting plate 302, a gear 304 is fixedly connected to the output end of the motor 303, tooth plates 306 are provided on the front and rear sides of the gear 304, the inner sides of the two tooth plates 306 are meshed with the outer sides of the gear 304, connecting rods 307 are fixedly installed on the bottom of the two tooth plates 306, and clamping plates 308 are fixedly installed on the bottom of the two connecting rods 307, sliding rods 305 are fixedly installed on the front and rear sides of the inner side of the frame 301, the two tooth plates 306 are slidably connected to the surfaces of the two sliding rods 305, and movable grooves 309 are provided on the front and rear sides of the bottom of the inner cavity of the frame 301, and the two connecting rods 307 pass through the inner cavity of the two movable grooves 309 and extend to the bottom of the frame 301.
[0033] By setting the connecting plate 206, the downward pressure of the goods when moving downward can be converted into an extrusion force toward the inside, and the extrusion force can be buffered by the tension of the hard spring 205 itself. By setting the moving groove 207, the moving direction of the slider 203 can be limited to avoid the slider 203 from deflecting when moving, thereby affecting the buffering work of the goods. By setting the hydraulic pipe 208, the inner rod 209, the circular plate 210 and the oil valve 211, when the goods drive the pallet 8 to press the circular plate 210 downward to move, the inner rod 209 moves downward synchronously, and the hydraulic oil in the inner cavity of the hydraulic pipe 208 buffers the downward pressure of the inner rod 209. The cargo can be fixed by setting a fixing mechanism 3 to avoid the cargo moving in the left and right directions when passing through a bumpy road section, causing the inner wall of the vehicle body 1 to be deformed due to the impact force of the cargo. The sliding rod 305 can guide the tooth plate 306 to avoid the cargo moving in the left and right directions, which may cause the cargo to be unable to be fixed. The movable groove 309 can limit the moving direction of the connecting rod 307 to avoid the connecting rod 307 moving in a deflection, causing the moving direction of the splint 308 to change synchronously, which may cause the cargo to be unable to be fixed.
[0034] When the utility model is working: the goods are placed on the top of the support plate 8, and then the output end of the motor 303 drives the gear 304 to rotate, so that the tooth plate 306 moves inward by cooperating with the gear 304, and the tooth plate 306 moves, and the connecting rod 307 drives the clamping plate 308 to move inward synchronously, and the connecting rod 307 completes the fixation of the goods. When the vehicle passes through a bumpy road section, causing the goods to move up and down, the support plate 8 moves up and down synchronously. With the movement of the support plate 8, the connecting plate 206 flips outward and pushes the slider 203 to move inward. At the same time, the hard spring 205 is deformed due to the extrusion of the slider 203, and its own tension pushes the slider 203 to move back and forth outward. As the slider 203 moves back and forth, the connecting plate 206 flips back and forth inside and outside, and makes the support plate 8 and the goods move back and forth up and down, gradually buffering the downward pressure of the goods when they are moving downward. At the same time, as the support plate 8 moves, the circular plate 210 drives the inner rod 209 to move downward synchronously, and squeezes the hydraulic oil in the hydraulic pipe 208, thereby weakening the downward pressure of the circular plate 210 when it is moving downward, thereby achieving buffering of the goods.
[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
