Description

Technical Field

[0001] The utility model relates to the technical field of trailer tooling, and particularly relates to a trailer tooling for a mining dump truck. Background Art

[0002] Mining dump trucks belong to off-road dump trucks and are used in off-road field sites such as large open-pit mines and water conservancy projects for transporting materials such as coal, sand, and gravel. Open-pit mines have the characteristics of harsh environments, large operating loads of mining trucks, and long working hours. Since the mining transportation routes are relatively narrow and single, once a mining truck stops due to certain failures, insufficient fuel, or insufficient power, if the shutdown failure cannot be quickly resolved or fuel cannot be refilled in time, it will affect the waiting trucks from continuing transportation, thereby reducing the efficiency of mining material transportation. Therefore, all mines are equipped with trailers, and once a problem that cannot be processed in a short time is found, the target vehicle can be quickly taken off the operation line for maintenance and repair.

[0003] Since the load capacity of mining dump trucks is very large, the vehicle self-weight ranges from dozens of tons to one or two hundred tons, and the strength requirements for the trailer tooling itself are very high. Currently, there is a lack of such trailer tooling for mining dump trucks. Summary of the Utility Model

[0018] The following description fully shows the specific embodiments of the present utility model, enabling those skilled in the art to practice and reproduce.

[0019] As Figure 1 shown, it is the front view of the trailer tooling for mining dump trucks in the present utility model; as Figure 2 shown, it is the top view of the trailer tooling for mining dump trucks in the present utility model; as Figure 3 shown, it is the exploded view of the structure of the trailer tooling for mining dump trucks in the present utility model.

[0020] The trailer tooling for mining dump trucks includes: a tooling body 1, a connecting pin 2, and a split pin 3.

[0021] The tooling body 1 includes: a bottom plate 11, a top plate 12, connecting vertical plates 13, limiting vertical plates 14, and supporting vertical plates 15. The bottoms of multiple supporting vertical plates 15 are connected to the top of the bottom plate 11, and the top plate 12 is connected to the tops of multiple supporting vertical plates 15; two limiting vertical plates 14 are respectively connected to both sides of the top plate 12, the bottom of the limiting vertical plate 14 is connected to the top of the bottom plate 11, and the limiting vertical plate 14 is provided with a first vertical plate through-hole; two connecting vertical plates 13 are located on both sides of the limiting vertical plate 14, the bottom of the connecting vertical plate 13 is connected to the top of the bottom plate 11, the connecting vertical plate 13 is provided with a second vertical plate through-hole, the second vertical plate through-hole is provided with a connecting pin cylinder 131, and the connecting pin cylinder 131 is provided with a second connecting through-hole; a connecting pin 2 is inserted into the connecting pin cylinder 131 and the second vertical plate through-hole, and the connecting pin 2 is provided with a first connecting through-hole; a split pin 3 is inserted into the first connecting through-hole and the second connecting through-hole.

[0022] To facilitate the positioning of the trailer, the limiting vertical plate 14 is provided with a limiting groove 141, the top plate 12 is provided with a first positioning through-hole, the bottom plate 11 is provided with a second positioning through-hole, and a positioning pin cylinder 142 is connected at the first positioning through-hole and the second positioning through-hole. The positioning pin cylinder 142 is funnel-shaped, and the inner diameter of the bottom is larger than that of the top, which is convenient for the installation of the trailer hook of the trailer. Of course, the tooling body 1 can also be directly welded to the trailer.

[0023] The height of the limiting vertical plate 14 is higher than that of the top plate 12 and the connecting vertical plate 13.
