Description

Technical Field

[0001] This utility model relates to the field of semi-trailers, and more particularly to a multi-purpose pull-out semi-trailer. Background Technology

[0002] The design concept of the pull-out semi-trailer originates from the traditional semi-trailer, but the introduction of a pull-out structure significantly improves its transport capacity and adaptability. Semi-trailers first appeared in the late 19th and early 20th centuries, initially mainly used for agricultural and industrial transport. With the development of internal combustion engines and highway infrastructure, semi-trailers have gradually evolved into the main tool for long-distance freight transport.

[0003] While existing technologies utilize pull-out semi-trailers to transport large objects, the inability of the vehicle to be secured promptly upon extension to the designated position results in low stability during transport and poses significant safety hazards. Therefore, those skilled in the art have developed a multi-purpose pull-out semi-trailer to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a multi-purpose pull-out semi-trailer. It provides a multi-purpose pull-out semi-trailer that can be adapted to different heights of the vehicle by setting a traction device, thereby effectively improving the overall applicability of the equipment. It also improves the overall stability of the equipment by setting a moving device.

The traction device is slidably disposed at the front end of the moving device. The traction device includes a support plate. A fixed frame is fixedly connected to the top center of the support plate. Connecting frames are rotatably connected to the upper sides of the fixed frame. First telescopic rods are rotatably connected to the rear sides of the inner sidewalls of the connecting frames. Sliding rods are fixedly connected to the rear sides of the support plate. The sidewalls of the two sliding rods are linearly arrayed with several through holes. Limiting plates are fixedly connected to the rear ends of the two sliding rods.

[0006] Through the above technical solution, by setting a traction device, a fixed frame is set at the top of the support plate, and a connecting frame is rotatably set at the top of the fixed frame. The tilt angle of the connecting frame can be adjusted by extending and retracting the first telescopic rod, which can effectively make the vehicle as a whole adaptable to vehicle heads of different heights, and effectively improve the overall applicability of the equipment.

[0008] Through the above technical solution, by setting up a moving device and installing a mounting bracket at the bottom of the vehicle body, the position of the two second telescopic rods can be effectively adjusted by driving the lead screw to rotate through the motor. After the slide rod is adjusted, the second telescopic rod is aligned with the through hole in the slide groove and the second telescopic rod is extended to cooperate with the through hole, thereby fixing the entire traction device and effectively improving the overall stability of the device.

[0009] Furthermore, the movable ends of the two first telescopic rods are respectively rotatably connected to the top two sides of the support plate;

[0010] The above technical solution effectively adjusts the angle of the connecting frame.

[0011] Furthermore, the movable ends of the two second telescopic rods respectively pass through the sliding groove and several through holes to be mutually adapted;

[0012] The above technical solution effectively fixes the slide bar.

[0013] Furthermore, the output end of the motor is fixedly connected to the front end of the lead screw through the front end of the mounting bracket;

[0014] The above technical solution effectively drives the slider to move.

[0015] Furthermore, the two sliding rods are respectively fixedly connected to the front end of the sliding shell and the limiting plate;

[0016] The above technical solutions effectively improve safety and prevent detachment.

[0017] Furthermore, the two fixed ends of the first telescopic rods are rotatably connected to both sides of the inner sidewall of the connecting frame;
