Description

Technical Field

[0001] The utility model belongs to the technical field of transport binding and relates to an automatic binding device for a transport vehicle. Background Art

[0002] When a passenger car leaves the factory, it needs to be transported to various dealers by a transport vehicle for sale. When loading the passenger car, the passenger car is driven onto the loading plate of the transport vehicle and then the wheels of the passenger car are locked by the automatic tying device on the transport vehicle. There are various automatic tying devices in the prior art. For example, Chinese patent application number 202210663555.9 discloses a wheel fixing assembly, a vehicle fixing device and a vehicle transfer equipment, including a base mounted on the top of the vehicle loading plate, a rotating member rotatably connected to the base, a strap connected between the rotating member and the base, and the rotation of the rotating member can tighten or release the strap tension to achieve fixing or releasing the wheels of the passenger car.

[0003] In the above scheme, the wheels of the passenger car are tightened and fixed by the rotating part strap. The rotating part serves two purposes, which is to reel in the strap and to tighten or release the strap. The locking mechanism is relatively simple. Once a failure occurs, it will directly affect the stability of the entire binding device. There is no redundant mechanism to ensure safety. Relying solely on the rotating part to tighten the strap cannot provide continuous and stable locking. Secondly, in order to ensure that the strap is always in a tensioned state during the transportation of the passenger car, the rotating part is always in a working state. Long-term work will cause the rotating part to fatigue due to long-term load, resulting in wear or failure, which will affect the binding accuracy, thereby affecting the stability and safety of the binding and reducing the performance of the automatic binding device. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the existing technology and propose an automatic binding device for a carrier vehicle. The technical problem to be solved by the utility model is: how to ensure the stability of binding and improve the performance of the automatic binding device.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] An automatic binding device for a carrier vehicle, the carrier vehicle includes a carrier plate, the binding device includes a binding strap and a rotating shaft rotatably connected to the bottom of the carrier plate, one end of the binding strap is fixed to the rotating shaft, and the device is characterized in that the other end of the binding strap passes through the carrier plate upward, and a clamping assembly capable of clamping the binding strap is provided at the position where the binding strap passes through the carrier plate.

[0007] Before transporting a passenger car, the vehicle is driven onto the loading plate, and the straps wrapped around the rotating shaft are released by rotating the rotating shaft, so that the straps can be pulled out along the circumference of the tire and the pulled end is positioned, and then the straps are clamped and locked by the clamping assembly. The two functions of retracting and locking the straps are respectively mapped to two different mechanical parts, the rotating shaft and the clamping assembly. The rotating shaft is the main source of tension for the straps. After bundling, the straps are clamped by the clamping assembly to keep the straps in a tensioned state. At this time, the rotating shaft can be in a standby state to reduce the workload of the rotating shaft. If the clamping assembly fails, the rotating shaft can continue to work as a second solution to keep the straps in a tensioned state, which does not affect the bundling and locking of the passenger car, reduces the risk of a single failure point, improves the reliability of the bundling and locking, and improves the performance of the automatic bundling device while ensuring the stability of the bundling.

[0008] In the above-mentioned automatic binding device for a carrier vehicle, the clamping assembly includes a clamp head and a clamping head fixed on the top of the carrier plate, the clamping head is located between the clamp head and the rotating shaft, a part of the strap is located between the clamp head and the clamping head, the clamping head is connected to a driving member capable of moving the clamp head toward the clamp head, and the rotating shaft is horizontally arranged perpendicular to the moving direction of the clamp head. The clamping head is driven by the driving member to move so that the clamping head can move toward the clamp head, thereby clamping or loosening the part of the strap located between the clamp head and the clamp head.

[0009] In the above-mentioned automatic binding device for a transport vehicle, a belt outlet hole is provided on the vehicle loading plate, the clamping head partially extends upward from the belt outlet hole, and the driving member is fixed at the bottom of the vehicle loading plate. The setting of the belt outlet hole enables the strap to pass through the vehicle loading plate more conveniently, and fixing the driving member at the bottom of the vehicle loading plate can, on the one hand, hide the driving member to improve the neatness and aesthetics of the top of the vehicle loading plate, and on the other hand, protect the driving member to prevent the vehicle to be transported from causing damage to the driving member when it drives onto the vehicle loading plate.

[0010] In the above-mentioned automatic binding device for a carrier vehicle, the clamp head has grooved teeth, and the portion of the clamp head extending out of the belt outlet hole has engaging teeth that match the shape of the grooved teeth. In the process of locking the strap, the grooved teeth of the clamp head and the engaging teeth of the clamp head engage with each other to form a firm lock. The cooperation of the grooved teeth and the engaging teeth causes the strap to bend and deform when the strap is fixed, increasing the friction between the strap and the clamp head and the clamp head. The clamped portion of the strap is provided with sufficient friction and anti-slip ability by this engaging mechanism, and is not easy to loosen or move, forming a firm lock, and the structure is stable and reliable.

[0011] In the above-mentioned automatic bundling device for a carrier vehicle, the driving member is a hydraulic cylinder, the piston rod of the hydraulic cylinder is fixed to the lower part of the clamping head, and the piston rod of the hydraulic cylinder is perpendicular to the rotating shaft and horizontally toward the side where the clamping head is located. The hydraulic cylinder has excellent force transmission and control performance. Using the hydraulic cylinder as a driving member can realize efficient automatic bundling operation and provide sufficient strength and stability.

[0012] In the above-mentioned automatic bundling device for a transport vehicle, the bottom of the vehicle plate has two relatively spaced fixed plates, the two fixed plates are arranged along the length direction of the piston rod of the hydraulic cylinder, the two fixed plates have long strip-shaped guide grooves, the two guide grooves are arranged along the length direction of the fixed plates, and the two sides of the lower part of the clamping head are protruding with guide parts, and the two guide parts are respectively slidably inserted in the two guide grooves. The setting of the guide groove has a guiding effect and a vertical limiting effect on the movement of the clamping head, so that the clamping head can slide smoothly in the guide groove and avoid the problem of unstable locking caused by the shaking of the clamping head during the driving of the transport vehicle, further improving the reliability and stability of the winding and locking structure.

[0013] In the above-mentioned automatic binding device for a carrier vehicle, two protrusions extend downward from both sides of the clamping head, and a guide roller is connected between the two protrusions. The guide roller is parallel to the rotating shaft and close to the side with the engaging teeth. The setting of the guide roller guides the part of the strap that does not pass through the vehicle plate, so that after the strap is locked, the part of the strap between the guide roller and the clamped position can be close to a vertical state, so that the clamping head and the clamp head can clamp the strap with less effort and have a better locking effect.

[0014] In the above-mentioned automatic binding device for a carrier vehicle, the two ends of the rotating shaft are respectively rotatably connected to the two fixed plates, and one end of the rotating shaft is connected to a belt-retracting motor. When the strap is used to bind the wheel of the passenger vehicle, the belt-retracting motor is started to drive the rotating shaft to rotate and reel the strap, so that the strap is firmly bound to the wheel of the passenger vehicle, thereby realizing automatic reeling of the strap and improving the binding efficiency.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] 1. The straps are clamped by the clamping assembly to keep them in a tensioned state. At this time, the rotating shaft can be in a standby state to reduce the workload of the rotating shaft. If the clamping assembly fails, the rotating shaft can continue to work as a second solution to keep the straps in a tensioned state, which does not affect the binding and locking of the passenger car, reduces the risk of a single failure point, improves the reliability of the binding and locking, and improves the performance of the binding and locking system while ensuring the stability of the binding.

[0017] 2. The cooperation of the grooved teeth and the bite teeth makes the strap bend and deform when it is fixed, increasing the friction between the strap and the clamp head and the clamping head. The clamped part of the strap is provided with sufficient friction and anti-slip ability by this bite mechanism, which is not easy to loosen or move, forming a firm lock, and the structure is stable and reliable.

[0018] 3. The setting of the guide groove has a guiding effect and a vertical limiting effect on the movement of the clamping head, so that the clamping head can slide smoothly in the guide groove and avoid the problem of unstable locking caused by the shaking of the clamping head during the driving of the transport vehicle, further improving the reliability and stability of the winding locking structure.

Among them, the clamping assembly 4 includes a clamping head 41 and a clamping head 42 fixed on the top of the vehicle carrier plate 2, the clamping head 42 is located between the clamping head 41 and the rotating shaft 3, a part of the strap 1 is located between the clamping head 41 and the clamping head 42, and the clamping head 42 is connected to a driving member 43 that can move the clamping head 42 toward the clamping head 41. The rotating shaft 3 is horizontally arranged along a direction perpendicular to the moving direction of the clamping head 42. The clamping head 42 is driven by the driving member 43 to move so that the clamping head 42 can move toward the clamping head 41, thereby clamping or loosening the part of the strap 1 located between the clamping head 42 and the clamping head 41. The driving member 43 is a hydraulic cylinder, which has excellent force transmission and control performance. Using the hydraulic cylinder as the driving member 43 can realize efficient automatic bundling operation and provide sufficient strength and stability. The piston rod of the hydraulic cylinder is fixed at the lower part of the clamping head 42, and the piston rod of the hydraulic cylinder is perpendicular to the rotating shaft 3 and horizontally toward the side where the clamp head 41 is located.

[0027] The above-mentioned clamp head 41 has groove teeth 411, and the part of the clamping head 42 extending out of the belt hole 21 has engaging teeth 421 that match the shape of the groove teeth 411. In the process of locking the strap 1, the groove teeth 411 of the clamp head 41 and the engaging teeth 421 of the clamping head 42 bite each other to form a firm lock. The cooperation between the groove teeth 411 and the engaging teeth 421 makes the strap 1 bend and deform when fixing the strap 1, thereby increasing the friction between the strap 1 and the clamp head 41 and the clamping head 42. The clamped part of the strap 1 is provided with sufficient friction and anti-slip ability by this bite mechanism, and is not easy to loosen or move, thereby forming a firm lock with a stable and reliable structure.

[0028] The bottom of the vehicle loading plate 2 has two relatively spaced fixed plates 22, which are arranged along the length direction of the piston rod of the hydraulic cylinder.

When the strap 1 is tied to the wheel of the passenger car, the belt-retracting motor 6 starts to drive the rotating shaft 3 to rotate to reel the strap 1, so that the strap 1 is firmly tied to the wheel of the passenger car, realizing the automatic reeling of the strap 1 and improving the binding efficiency.

[0030] Before transporting a passenger car, the vehicle is driven onto the loading plate 2, and the strap 1 wound around the rotating shaft 3 is released by rotating the rotating shaft 3, so that the strap 1 can be pulled out along the circumference of the tire and the pulled-out end is positioned, and then the strap 1 is clamped and locked by the clamping assembly 4.

[0031] The utility model corresponds the two functions of retracting and releasing the strap 1 and locking the strap 1 to two different mechanical components, namely the rotating shaft 3 and the clamping assembly 4, wherein the rotating shaft 3 is the main source of tension for the strap 1. After bundling, the strap 1 is clamped by the clamping assembly 4 to keep the strap 1 in a tensioned state. At this time, the rotating shaft 3 can be in a standby state to reduce the workload of the rotating shaft 3. If the clamping assembly 4 fails, the rotating shaft 3 can continue to work as a second solution to keep the strap 1 in a tensioned state, which does not affect the bundling and locking of the passenger car, reduces the risk of a single failure point, improves the reliability of the bundling and locking, and ensures the stability of the bundling while improving the performance of the automatic bundling device.
