Description

Technical Field

[0001] The utility model belongs to the technical field of logistics binding tools and relates to a tire binding device for an automobile. Background Art

[0002] When a car is transported by truck, ship or train, it needs to be fixed. The tire of the car is the part that can be easily fixed without damaging the car. Among them, the tire binding device is a device that fixes the wheels of the car to prevent the vehicle from moving randomly during transportation.

[0003] At present, the existing tire bundling devices generally perform tire bundling operations by manual operation. For example, Chinese patent CN206705126U discloses a tire carrier rail vehicle, which is actually also a tire bundling device, characterized in that: two parallel tire carrier connecting beams are connected to the tire carrier housing at both ends, two bearings are fixed in the bearing sleeve, the roller and the roller shaft are rotatably connected to the two bearings, the outer ends of the roller and the roller shaft are fixedly connected to the gear, and the inner ends are connected to the roller shaft connecting rod through the pin shaft, the ratchet is placed in the groove on the tire carrier housing, the ratchet hexagonal shaft is fixedly connected to the ratchet, the ratchet pawl fixed shaft is fixedly connected to the tire carrier housing, the ratchet pawl is rotatably connected to the ratchet pawl fixed shaft, one end of the tire strap is fixed on the ratchet, and the other end is fixed on the tire strap pull ring, the tire strap pull ring is hinged to one end of the ratchet pawl, the other end of the ratchet pawl is meshed with the upper part of the ratchet, and the gear is meshed with the rack guide track.

[0004] The specific operation process of the tire carrier rail vehicle for bundling the tire is as follows: when the car tire is moved into place, the strap is manually pulled out from the ratchet and wrapped around the top of the tire from bottom to top until the strap pull ring is hinged to the ratchet pawl. At this time, the pawl is not buckled on the ratchet and the ratchet can rotate clockwise; after completing the strap pulling and preliminary bundling operations, the tire strap is driven to wrap around the ratchet by using the hexagonal socket to rotate the ratchet hexagonal shaft counterclockwise. The strap pull ring pulls the ratchet pawl to rotate counterclockwise around the ratchet fixed axis, so that the ratchet pawl buckles the ratchet and cannot rotate clockwise, thereby achieving bundling locking and finally completing the tire bundling operation. It can be seen that the existing tire tying device has the following defects when performing manual tying operation: 1. Since the gap between the tire and the vehicle body is relatively small, it is inconvenient to manually pull out the strap and wrap it around the tire; 2. The device requires manual tools to tighten and lock the strap, which is cumbersome to operate; 3. Since the entire tying process is manually operated, it is not only time-consuming and labor-intensive, but also the tying quality depends entirely on manual self-control, resulting in the tying quality being inconsistent and prone to loosening. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the prior art and to propose a tire binding device for automobiles. The technical problem to be solved by the utility model is how to improve the binding efficiency and the binding quality at the same time.

[0006] The object of the utility model can be achieved through the following technical scheme: a tire binding device for a car, comprising a carrier, a winding shaft rotatably connected to the carrier, and a binding belt, wherein the binding belt is wound on the winding shaft, and is characterized in that a winding drive member is provided on one side of the winding shaft, and the winding drive member can drive the winding shaft to rotate to reel the binding belt.

[0007] Different from the tire bundling devices in the prior art that require manual operation, the present invention, by designing a set of fully automated structures, does not require manual work for a series of operations such as pulling the strap, bundling, locking, winding, tightening, etc., so that the entire bundling process does not require manual work and is fully automated, thereby achieving the purpose of improving bundling efficiency while improving bundling quality. Specifically, by designing a winding drive on one side of the winding shaft, the winding shaft can be automatically rotated by the drive of the winding drive to achieve automatic winding of the binding belt; at the same time, by providing a swing arm and a swing arm drive that can swing in the front and rear directions of the platform on the carrier, and fixing a guide arm extending along the left and right directions of the platform at the free end of the swing arm, the guide arm is used to be connected to the free end of the binding belt. After such a design, the swing arm can drive the guide arm to pull the binding belt out from the winding shaft under the drive of the swing arm drive, and because the swing arm swings along the front and rear directions, the guide arm is along The tying belt extends in the left and right directions, so that the tying belt can be tied around the outer circumference of the tire, thereby realizing the automation of pulling and tying. Subsequently, a clearance opening is designed on the upper surface of the platform, and a clamping block that can slide along the front and rear direction of the platform is designed at the clearance opening. On the one hand, this design makes the final locking position of the tying belt as flush with the bottom of the tire as possible or below the bottom of the tire, which is conducive to tightening the tire and improving the tying quality. On the other hand, the design of the clearance opening can also make the installation position of the clamping block hidden as far as possible below the platform or hidden to a position almost flush with the upper surface of the platform. , so that it will not hinder the movement of the automobile tire to the bundling position of the carrier, making the automobile bundling process smoother and improving the bundling efficiency; and, through the design of the above-mentioned yielding mouth and clamping block, when the guide arm swings with the swing arm and enters the yielding mouth, a locking driving member is provided on one side of the clamping block, and the locking driving member can drive the clamping block to move and lock the guide arm in the yielding mouth, so as to realize automatic locking after the pull belt is tied, and because it is the guide arm that is locked, not the bundling belt, it can be locked more easily and not easy to loosen, thereby improving the bundling quality; after the bundling is locked, the above-mentioned winding driving member can also drive The rotation of the winding shaft causes the binding belt to be reeled up to further tighten the binding belt, thereby further improving the binding quality while realizing the automation of the tightening operation; after the binding is released, the winding drive component can also drive the winding shaft to rotate to automatically reel the binding belt back; therefore, the utility model achieves the purpose of automating each operation step through the three-drive design of the above-mentioned winding drive component, the swing arm drive component and the locking drive component in combination with the transmission structure design of the swing arm, the guide arm, the give way and the clamping block, and after full automation, not only the binding is fast and efficient, but also there is no arbitrariness of human factors and the binding quality is good.
