[0026] Example 1

[0027] like Figures 1-3 As shown, a vehicle-mounted loading and unloading platform with traction function includes a traction device. One end of the traction device is connected to the tow hook on the transport vehicle, and the other end of the traction device is slidably connected to a connecting component. The connecting component is welded and fixed to the main body 6 of the vehicle-mounted loading and unloading platform.

[0028] The working principle of the above technical solution is as follows: The function of the traction device and the connecting component is to connect the transport vehicle to the on-board loading and unloading platform. The traction device can slide up and down within the connecting component, thereby changing the height of the traction device to adapt to the towing hook height of different transport vehicles.

[0029] Example 2

[0030] like Figures 1-3 As shown, the connecting component includes a traction support 5 and a pin 3. The traction support 5 is welded and fixed to the main body 6 of the vehicle loading and unloading platform, and the end of the traction device slides in the groove on the traction support 5.

[0031] The traction support 5 is provided with multiple insertion holes a, and the end of the traction device is provided with an insertion hole b. After the insertion hole b coincides with one insertion hole a, the pin 3 is inserted into the insertion hole a and the insertion hole b to fix the traction device to the traction support 5.

[0032] The working principle of the above technical solution is as follows: the end of the traction device slides in the groove on the traction support 5, so that the height of the traction device is adapted to the height of the towing hook of the transport vehicle. The insertion hole b at the end of the traction device coincides with the insertion hole a on the traction support 5. The pin 3 is inserted into the insertion hole a and the insertion hole b to fix the traction device and the traction support 5, preventing the traction device and the traction support 5 from sliding or separating, thereby connecting the transport vehicle to the main body 6 of the loading and unloading platform.

[0033] Example 3

[0034] like Figures 1-3 As shown, the traction device includes a traction device frame 2, one end of which is rotatably connected to the traction ring 1, and the other end of which slides in the groove of the traction support 5.

[0035] The end of the traction device frame 2 is provided with a socket b. The pin 3 is inserted into the socket a and the socket b to fix the traction device frame 2 to the traction support 5.

[0036] The working principle of the above technical solution is as follows: the end of the traction device frame 2 slides in the groove on the traction support 5, so that the height of the traction device frame 2 is adapted to the height of the towing hook of the transport vehicle. The insertion hole b at the end of the traction device frame 2 coincides with the insertion hole a on the traction support 5. The pin 3 is inserted into the insertion hole a and the insertion hole b to fix the traction device frame 2 and the traction support 5, preventing the traction device frame 2 and the traction support 5 from sliding or separating, thereby connecting the transport vehicle with the main body 6 of the loading and unloading platform.

[0037] The main body of the truck loading and unloading platform 6 consists of a truck trailer, a lift, and a transition plate. The lift is installed on the truck trailer, and a transition plate is installed on the lift. Goods are placed on the transition plate, and the lift raises the goods and sends them into the transport vehicle, or lowers the goods to the lowest point for unloading.

[0038] The traction support 5 is welded to the trailer.

[0039] Example 4

[0040] like Figures 1-3 As shown, the traction ring 1 consists of a front ring structure and a rear threaded rod structure. The ring structure is hooked to the traction hook on the transport vehicle, and the threaded rod structure is inserted through the traction device frame 2 and fastened to the end of the threaded rod structure by a nut.

[0041] The working principle of the above technical solution is as follows: the traction ring 1 can rotate on the traction device frame 2, and the circular structure at the front end of the traction ring 1 can also rotate, which makes it convenient for the circular structure to be hooked to the traction hook of the transport vehicle.

[0042] The traction ring 1 is used for transporting the vehicle to pull the on-board loading and unloading platform body 6 forward or backward, and the front end ring structure can make the on-board loading and unloading platform body 6 produce corresponding steering behavior with the transport vehicle.

[0044] As shown in Figures 1-3 The latch 3 includes a latch body 303, one end of the latch body 303 is fixed with a pull rod 301, the other end of the latch body 303 is provided with a limiting hole 304, and the connection part of the latch body 303 and the pull rod 301 is provided with a baffle 302.

[0045] The latch body 303 is inserted into the insertion hole a and the insertion hole b to fix the traction device frame 2 and the traction support 5.

[0046] The working principle of the above technical scheme is that after the insertion hole b at the end of the traction device frame 2 coincides with the insertion hole a on the traction support 5, the pull rod 301 is held by hand, the latch body 303 is inserted into the insertion hole a and the insertion hole b, and after being inserted into the preset position, the baffle 302 is abutted against the outer wall of the traction support 5, the iron wire is inserted into the limiting hole 304 arranged at the end of the latch body 303, and the two ends of the iron wire are wound with each other to prevent the iron wire from automatically moving out of the limiting hole 304 and also prevent the latch body 303 from automatically moving out of the insertion hole a and the insertion hole b. The pull rod 301 is designed as a bent rod to facilitate pulling.

[0047] Embodiment six

[0048] As shown in Figures 1-3 The traction device frame 2 is triangular, two vertical rods 7 are welded in the traction device frame 2, and a horizontal rod 8 is welded between the two vertical rods 7.

[0049] The working principle of the above technical scheme is that the traction device frame 2 is designed as a triangle and is reinforced by the vertical rods 7 and the horizontal rod 8, so that the traction device frame 2 has strong stability and is not easy to deform under a large pulling force.

[0050] The traction device frame 2 is used for dispersing the force transmitted by the transport vehicle to the traction ring 1 to the front end frame of the on-board loading and unloading platform body 6, and the length of the traction device frame 2 determines the minimum turning radius of the on-board loading and unloading platform body 6.

[0051] Embodiment seven
