Description

Binding device for car transportation vehicle

Technical Field

The invention belongs to the technical field of logistics binding tools, and relates to a car transportation vehicle binding device.

Background

During transportation of the vehicle by truck, ship or train, the vehicle needs to be fixed. The car transportation binding device is a device for fixing wheels of a vehicle to prevent the vehicle from moving randomly in the transportation process.

For example, the chinese patent document discloses an automatic take-up mechanism (application No. 201710048105.8; publication No. CN106799986A) for a wheel holder, which includes a housing, a reel rotatably connected in the housing for taking up a fastening tape, the reel having the fastening tape wound thereon, a ratchet fixed on the reel, and a locking member hinged to the housing and having a pawl. In the process of fixing the vehicle, the wheel fixer realizes the tightening of the binding belt by rotating the reel by an operator through a tool. When the wheel fixer is used, the wheel fixer is placed on the floor of a truck for binding operation, so that the distance between the reel and the floor of the truck is small, and at the moment, the reel needs to be rotated by a tool, the operation space is small, so that the process of rotating the reel is very troublesome, the time is wasted, and the operation convenience is poor. Furthermore, the manual operation requires a high labor consumption, especially in the later stage of binding, and thus the application of the wheel holder is laborious.

The existing logistics binding tool also has a related structure which drives the reel to rotate in a motor driving mode. For example, the belt retracting device (application No. 200820199005.1; publication No. CN201347208Y) of a tightener disclosed in chinese patent document comprises a support and a rotating belt shaft, wherein one end of the belt shaft extends out of the support and is fixedly connected with a worm wheel, and a worm shaft, a motor and a transmission mechanism capable of driving the worm shaft to rotate by the motor are arranged on the same side of the support. Although the device is provided with the motor, the motor drives the belt shaft to rotate by means of the transmission mechanism, the worm shaft and the worm wheel, the automatic belt winding function is realized, the automation degree is high, and the trouble caused by manual operation is avoided. However, in the device, the motor, the worm shaft, the worm wheel and the transmission mechanism are all arranged on the same side of the bracket, and a certain distance needs to be reserved between the motor and the worm shaft to realize the installation of the transmission mechanism, so that the device comprises the bracket, the worm and gear mechanism, the motor and the reserved distance between the motor and the worm shaft in the length direction, and the device is longer in length, large in overall occupied space and influenced in use convenience. Moreover, when the motor drives the worm shaft to rotate, in order to achieve a large binding force, multiple groups of gears need to be arranged between the rotating shaft of the motor and the worm for speed reduction transmission, so that the large binding force is achieved on the premise that the output torque of the motor is constant, however, the space required for arranging the multiple groups of gears is large, and therefore, if the belt retracting device needs to achieve the large binding force, the distance between the motor and the worm shaft needs to be increased to arrange more gears, so that the size of the device is further increased, and therefore, the structural design of the device is difficult to achieve comprehensive optimization of the binding force and the space design.

In the state where the worm 8 is completely meshed with the worm wheel 7, the meshing pawl 20 does not contact the helical teeth 83. In fig. 13, the worm wheel 7 rotates clockwise in the direction of rotation for tightening the binding band 5, and conversely, in the direction of rotation for loosening the binding band 5. After the worm 8 stops rotating, because the counterclockwise rotating direction of the worm wheel 7 is the direction of loosening the binding belt 5, but the counterclockwise rotating of the worm wheel 7 drives the worm 8 to have the tendency of moving towards the left end, at this time, the second shaft sleeve 15 abuts against the spiral teeth 83 of the worm 8, and the movement of the worm 8 towards the left end is limited, so that the self-locking function of the worm wheel 7 is realized, and the worm wheel 7 is prevented from rotating towards the belt loosening direction.

When the binding belt 5 needs to be loosened, only the motor needs to be controlled to rotate reversely, the worm 8 rotates reversely, the worm 8 moves towards one end of the driven gear 11 until the worm 8 and the worm wheel 7 are not meshed with each other, the worm wheel 7 is enabled to realize neutral gear at the moment, and the reel 6 can rotate freely to pull out the binding belt 5 conveniently and quickly.
