Description

Binding device for car transportation vehicle

Technical Field

The invention belongs to the technical field of logistics transportation equipment, and relates to a car transportation vehicle binder.

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 a car carrier binder (application number: 201910040354.1; publication number: CN 109733268A), which comprises a mounting plate and a supporting plate for supporting against a wheel, wherein one side surface of the supporting plate is fixedly connected with a first side plate and a second side plate which are oppositely arranged, the mounting plate is respectively connected with the side edge of the first side plate and the side edge of the second side plate, a reel for winding a binding belt is rotatably arranged between the first side plate and the second side plate, one end of the reel penetrates through the side plates and is connected with a worm wheel, a worm meshed with the worm wheel is arranged on the outer side surface of the first side plate, a motor is arranged on the outer side surface of the second side plate, and a transmission structure for driving the worm to rotate by the motor is arranged on the side surface of the mounting plate. The binding device of the sedan car transportation vehicle with the structure of the electric type drives the scroll to rotate through the motor, when the power supply is in power shortage, the binding device of the sedan car transportation vehicle is provided with the hexagonal columnar connecting part at the end part of the worm, so that the device can drive the worm to rotate by rotating the connecting part, and manual operation is realized. However, when the car carrier binding device is used, the abutting plate abuts against an automobile tire, and the whole car carrier binding device is located below a chassis of an automobile body, so that when a tool is used for rotating the rotating part of the worm, the operating space is very narrow, and the manual operation of the car carrier binding device is very troublesome.

At present, in order to realize that the car transportation vehicle binding device can be conveniently operated manually, the conventional technical means is as follows:

1. the end part of the scroll is directly processed with a rotating part in an external hexagonal shape, the mode has simple structure and direct transmission of operating force, and is the longest structure adopted by the binding band of the existing manual car transportation vehicle; for example, the Chinese patent document discloses an automatic belt-retracting mechanism of a wheel fixer (application number: 201710048105.8; grant publication number: CN 106799986B);

2. the wheel is fixed by a binding device with an operating spanner. For example, the new binding and fixing device (application number: 200620070468.9; publication number: CN2925686) for vehicle transportation disclosed in chinese patent document can tighten the binding band by only pulling the operation wrench on the ratchet tightening machine without using an additional tool when fixing the wheel, thereby facilitating the operation under the vehicle chassis.

3. The rotating part of the worm rotates in a narrow space is realized by using a special wrench. For example, the electric wrench or the ratchet wrench, when the electric wrench is used, the worm can be driven to rotate only by turning on the power switch. When the ratchet wrench is operated, the worm is driven to rotate only by swinging back and forth without loosening the rotating part. Power wrenches or ratchet wrenches are well known in the mechanical arts as tools suitable for use in confined spaces.

The working principle of the car carrier binding device is briefly described in the following with reference to fig. 5: in use, the connecting hook 20 on the bottom plate 1a is hooked on the carriage floor, and when the hole plate is placed on the carriage floor, the connecting hook 20 is hooked on the hole plate. Then, the back-and-forth distance of the abutting plate 1b is adjusted to make the abutting plate 1b stably abut against the outer peripheral surface of the wheel, and then the tying band is wound around the outer peripheral surface of the wheel to hook the band hook at the end of the tying band onto the floor of the carriage, at this time, the tying band is still in a loose state. After the binding belt is arranged, the tool rotates the driving bevel gear 6, and the driving bevel gear 6 sequentially drives the synchronous bevel gear 5, the worm 3, the worm wheel 4 and the reel 2 to rotate, so that the binding belt is slowly tightened until the binding is finished. In addition, the car transportation binding device can also realize the engagement or separation of the worm 3 and the worm wheel 4 by pushing the worm 3 inwards or pulling the worm 3 outwards and matching the rotation of the worm 3, and when the worm 3 is separated from the worm wheel 4, the spiral teeth 33 of the worm 3 move to the rear of the worm wheel 4 and are not engaged with the worm wheel 4, so that the binding belt can be pulled out quickly, and the binding operation process is very convenient. Meanwhile, the car carrier bundler is provided with the synchronous bevel gears 5 on the worm 3, and the driving bevel gears 6 are arranged on the base body 1 and located on two sides of the worm 3 respectively, so that the car carrier bundler can be guaranteed to have one driving bevel gear 6 facing the outer side of a wheel whether being used for fixing the left wheel or the right wheel of an automobile, an operator can conveniently be located on the outer side of the wheel and can rotate the driving bevel gear 6 by using a tool, the binding operation is realized, and the convenience of manual operation is greatly improved.
