Description

Technical Field

[0001] This utility model relates to the field of bus traction, specifically to a bus traction device. Background Technology

[0002] Bus towing devices are mainly used to tow 6-12 meter buses in factories and industrial production, to tow vehicle bodies before the power battery is installed or other parts that need rework or repair. Currently, most factories use towing steel wire ropes or other steel pipes as connecting fixtures for towing. Due to the large mass and inertia of the bus body, either the towing device cannot stop with the bus at any time, or the towing device is prone to deformation when the bus brakes, posing significant safety hazards. Moreover, it is not easy to reach the designated towing position. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a bus towing device that enables the towed bus body to easily achieve forward steering and braking along with the towing trolley.

[0004] The purpose of this utility model is achieved through the following technical solution: This bus towing device includes a main body, which adopts a tubular structure. Both ends of the main body are fixed with sealing plates. Each sealing plate has a connecting plate on its surface away from the main body. The connecting plate at one end of the main body is used to connect to the towing joint of the towing vehicle, and the connecting plate at the other end of the main body is used to connect to the towing joint of the bus. At least one omnidirectional wheel is installed on the main body.

[0005] As a further technical solution, a locking hole is provided on the connecting plate, so that the traction joint and the connecting plate can be detachably connected through the locking hole.

[0006] As a further technical solution, the end of the connecting plate that connects to the traction joint is provided with an arc segment.

[0007] As a further technical solution, the main body is made of Q235 square tube, and a 30μm electrophoretic paint layer is provided on the surface of the main body. At the same time, a 50μm paint layer is also provided on the surface of the main body.

[0008] As a further technical solution, the block connecting plate maintains the same height relative to the main body.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. The main body is equipped with casters at the bottom, which makes it easy for the tow unit to turn synchronously with the towing vehicle during towing. The towing vehicle can also pull the tow unit from the designated position to the towing station independently, which is convenient for picking up and putting down.

[0011] 2. Locking holes are provided on the connecting plate to facilitate the detachable connection of the traction head, enabling flexible connection and disassembly;

[0012] 3. The connecting plates are at the same height relative to the main body to ensure that the height of the mounting bolts is basically the same during towing, and there will be no height difference between the towing vehicle, bus and towing device;

[0013] 4. The end of the connecting plate is provided with an arc section, which can interfere with the bus body and the tractor when the vehicle is not turning. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings:

[0019] Example: As attached Figures 1-3 As shown, this bus towing device includes a main body 1, a sealing plate 2, a connecting plate 3, an arc segment 4, a caster wheel 5, a towing vehicle 6, a bus 7, a towing joint 8, and a lock hole 9.

[0020] Reference Appendix Figure 1 The main body 1 is made of Q235 square tubing. Sealing plates 2 are welded to both ends of the main body 1. A connecting plate 3 is welded to the surface of each sealing plate 2 facing away from the main body 1. The connecting plate 3 is fixed perpendicularly to the sealing plate 2. For example... Figure 2 , 3 As shown, each connecting plate 3 has a locking hole 9, which allows the traction joint 8 to be detachably connected to the connecting plate 3 through the locking hole 9 (and bolts).

[0021] Furthermore, the connecting plate 3 at the left end of the main body 1 can connect to the traction joint 8 at the rear of the tractor 6, and the connecting plate 3 at the right end of the main body 1 can connect to the traction joint 8 at the front of the bus 7. Preferably, the two connecting plates 3 are at the same height relative to the main body 1 to ensure that the height of the mounting bolts is basically the same during towing, and there will be no height difference between the tractor, the bus and the towing device.

[0022] Preferably, an arc segment 4 is provided at the end where the connecting plate 3 connects to the traction joint 8, so as not to interfere with the bus body 7 and the tractor 6 when turning, and to ensure stable vehicle operation during traction.

[0023] Furthermore, a caster wheel 5 is welded and fixed to the bottom of the main body 1, so that the towing device (bus 7) can turn synchronously with the towing vehicle 6 during towing, and the towing vehicle can also pull the towing device from the designated position to the towing station independently, which is convenient for picking up and putting down.

[0024] Preferably, a 30μm electrophoretic paint layer is formed on the surface of the main body 1, and a 50μm paint layer is also formed on the surface of the main body 1 to ensure the durability of the traction device tooling. The main body 1 is made of a square tube with a diameter of 80*80mm and a diameter of 5mm. After manufacturing, the total weight of the traction device is 20kg, which is convenient for handling.

[0025] The working process of this utility model is as follows: Before towing, the connecting plate 3 at the front end of the main body 1 is connected to the towing joint 8 at the rear of the towing vehicle 6 via bolts and locking holes 9. Then, the towing vehicle 6 can be started, pulling the towing device alone from the designated position (towing device placement position) to the towing station. Next, the connecting plate 3 at the rear end of the main body 1 is connected to the towing joint 8 at the front of the bus 7 via bolts and locking holes 9, completing the entire towing connection. The towing vehicle 6 is then started again, towing the bus 7 to the designated towing position. Due to the presence of the towing device, the bus 7 can easily achieve forward steering and braking with the towing vehicle 6.

[0026] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
