Description

Technical Field

[0001] The utility model relates to the field of highway emergency equipment, in particular to a tow truck used for clearing scattered parts caused by highway accidents. Background Art

[0002] When a traffic accident occurs on a highway, especially a busy highway, after emergency rescue of the injured, evidence collection and towing of the faulty vehicle, the next thing to do is to quickly clean up the goods left on the highway so that the highway can be reopened to traffic in the shortest possible time. If the accident leaves behind large items, they are generally small in number and concentrated, and it is relatively easy to quickly clean them up with lifting equipment; but if the accident leaves behind small loose items, such as express deliveries of different sizes with packaging boxes or light and loose small items scattered on the highway by the accident vehicle, they are often large in number and scattered, and need to be picked up one by one by hand and sent to a centralized point for concentration before being towed away by a truck. The cleaning work is heavy and inefficient, affecting the time it takes to quickly restore the highway to traffic. Therefore, highway management personnel hope to have a tow truck with a large collection bucket that can collect scattered residual items, which can flexibly cooperate with operators to collect and transport debris on the highway, and can also compact light and loose debris to improve the efficiency of cleaning operations and shorten the time for towing. In view of this, this case was created. Utility Model Content

The tow truck designed by the utility model has a flippable box bucket of a tow truck box unit rotatably connected to the swingable support arms of two sets of swing arm units. An openable door panel is provided at one end of the box bucket, and a pressure-extrusion assembly is provided at the other end. When the support arm is swung forward and the box bucket is flipped to a horizontal state, the door panel can be opened to collect scattered parts on the road. After the door panel is closed, the light and loose debris can be compacted by the extrusion assembly. When the support arm is swung backward to place the box bucket above the vehicle body's bucket and the box bucket is flipped to a vertical state, the door panel can be opened to automatically unload the debris into the vehicle bucket, thereby improving the efficiency of the tow truck removal operation and shortening the tow truck removal time.

When the box 311 is full or there are no more debris on the road that needs to be cleaned, the door panel 313 can be closed. If the debris is a light and loose part that takes up too much space, the second telescopic cylinder 322 of the extrusion assembly 32 can be started to push the pressing plate 321 in the direction of the door panel 313 to compact the debris.

[0033] The support arm 211 is then swung backward to place the box 311 at any position above the vehicle box of the vehicle body 1, and then the box 311 is turned over to a vertical position, and the door panel 313 is opened to automatically unload the residual parts to any position in the vehicle box.

[0034] The vehicle body 1 is provided with a support frame at the rear of the vehicle bucket. When the tow truck is not in operation, the support arm 211 can be swung to allow the upright box bucket 311 to fall onto the support frame and be fixed thereon.

[0035] The tow truck designed by the utility model has a flippable box 311 of the tow box unit 3 rotatably connected to the swingable support arms 211 of the two sets of swing arm units 2. An openable door panel 313 is provided at one end of the box 311, and a pressure-extrusion assembly 32 is provided at the other end. When the support arm 211 swings forward and the box 311 flips to a horizontal state, the door panel 313 can be opened to collect scattered parts on the road. After closing the door panel 313, the light and loose debris can be compacted by the extrusion assembly 32. When the support arm 211 swings backward to place the box 311 above the vehicle body 1 and the box 311 flips to a vertical state, the door panel 313 can be opened to automatically unload the debris into the vehicle body, thereby improving the efficiency of the tow removal operation and shortening the tow removal time.
