Description

Unilateral curved track side-dump mine car Technical Field The utility model relates to the technical field of mining equipment, in particular to a unilateral bent rail side dump type mine car. Background The single-side curved track side unloading mine car is a fixed-point unloading equipment for transporting various ores, waste stones and other materials in the construction transportation engineering such as metal ore, nonmetallic ore, bridge construction, railway engineering, transportation and tunneling, and is matched with an unloading curved track during unloading. The traditional device has obvious defects in the aspects of unloading operation and structural design. The unloading process is complicated and depends on manpower, so that the efficiency is low, the time consumption is long, incomplete unloading or equipment damage is easy to occur due to operation errors, and meanwhile, the problem of overlarge impact and vibration exists in the operation process of the mine car. The strong impact and vibration not only can cause serious damage to parts of the mine car, but also can influence the overall structural stability of the mine car. Thus, there is a need in the art to develop a single side track side dump car. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a unilateral curved track side dump type mine car. In order to achieve the aim, the utility model adopts the following technical scheme that the unilateral curved track side-dump type mine car comprises a car frame, wherein the left side and the right side of the car frame are respectively provided with a buffer and a bolt part, the front side and the rear side of the car frame are provided with hollow wheels, the middle part of the front side of the car frame is provided with an unloading wheel part, the top of the car frame is hinged with a car box part, and the rear side of the car box part is provided with a car door; The bolt portion includes the front end that links to each other with the frame, front end is connected with the single ring chain, the buffer includes the buffer seat that links to each other with the frame, the buffer seat is hollow structure and all is equipped with the through-hole about and is equipped with the screw rod between the through-hole of both sides, the cover is equipped with the spring on the screw rod, both ends are equipped with the spring holder that links to each other with the buffer seat about the spring, the left side of screw rod is equipped with back end, the right side of screw rod is equipped with locking subassembly.
