Description

Technical Field

[0001] The invention relates to the technical field of transportation equipment, in particular to a carriage for a mining vehicle. Background Art

[0002] A mining truck is a heavy-duty dump truck used in open-pit mines to complete rock and earth stripping and ore transportation tasks. Its working characteristics are short travel distance and heavy load. It is usually loaded with a large electric shovel or hydraulic shovel, and travels back and forth between the mining point and the unloading point.

[0003] The transport container of a mining vehicle is a carriage, which generally includes a carriage body consisting of a bottom plate front, side plates fixed upward on both sides, and a rear cover plate that can be opened and closed and installed on the rear side of the carriage body. During the loading and transportation of ore, especially for larger stones, the stones are prone to hit the upper part of the two side plates of the carriage body, which not only causes the two side plates of the carriage body to be easily damaged, but most importantly, the ore is prone to flip outward with the two side plates of the carriage body as the fulcrum and fall to the outside of the carriage body, making the loading and transportation safety of the mining vehicle unguaranteed.

[0004] Therefore, the research purpose of the present utility model is to design a mining vehicle carriage that can effectively cope with the impact of ore and can form a certain guiding effect when the ore hits the top of the two side plates of the carriage body, so that the stone can be guided into the carriage body, thereby significantly reducing the probability of the stone falling outside the carriage body. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the utility model provides a mining vehicle carriage, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A mining vehicle carriage, comprising

[0008] A carriage body, the rear end of which can be opened and closed and is provided with a corresponding rear cover plate;

[0009] Two sets of support seats are respectively fixedly mounted on the front and rear ends of both sides of the carriage body, and corresponding bearing seats are respectively mounted on the support seats through corresponding high-rigidity springs, and corresponding one-way bearings are respectively mounted on the bearing seats;

[0010] A group of guide rollers, both ends of which are fixedly mounted on corresponding one-way bearings, and corresponding buffer support members are respectively arranged between the bottom of the guide rollers and the carriage body.

[0011] The buffer support is made of rubber.

[0012] The bottom side of the buffer support is fixedly connected to the carriage body, the top of the buffer support is fixedly connected to an engineering plastic part with an arc-shaped top surface, and the guide roller is rotatably abutted against the top of the engineering plastic part.

[0013] The bottom of the carriage body is fixedly connected with a corresponding vehicle frame, and the carriage body can be flipped and installed on the rear side of the beam mechanism of the mining vehicle through the vehicle frame.

[0014] The frame is driven to flip by corresponding hydraulic cylinders.

[0015] A protective plate for protecting the driving cab of the mining vehicle is arranged forwardly on the upper front part of the carriage body.

[0016] The support seats are respectively provided with corresponding installation grooves, and the high-rigidity spring and the bottom of the bearing seat can be movably installed in the installation grooves respectively.

[0017] 1) The top of both sides of the car body of the utility model are respectively installed with corresponding guide rollers that can rotate unidirectionally, and corresponding buffer support members are respectively arranged between the guide rollers and the car body. During the loading process, when a large stone hits the guide roller, the buffer unloading force of the buffer support member can be used to reduce the mechanical damage to the car body; the most important thing is that in the process of the guide roller being hit, it is likely to form a corresponding inward unidirectional rotation to guide the large stone hitting it inward, so that the large stone can be introduced into the car body, thereby greatly reducing the probability of large stones falling outside the car body, so as to improve the loading and transportation safety of the present invention.

[0018] 2) The car body on both sides of the buffer support of the utility model is fixed with a support seat, and a bearing seat and a corresponding one-way bearing are respectively installed on the support seat through a high-rigidity spring, and then the two sides of the guide roller are respectively installed on the corresponding one-way bearing. When the guide roller is hit, the high-rigidity spring is pre-stressed and compressed, and then the buffer support is squeezed to form two buffer unloading forces on the guide roller, thereby effectively reducing the mechanical damage of the guide roller when it is hit.

[0019] 3) The bottom side of the buffer support of the utility model is fixed to the car body, and the top of the buffer support is fixed to an engineering plastic part with an arc-shaped top surface, and the guide roller rotates and abuts against the top of the engineering plastic part. With the intervention of the engineering plastic part, while ensuring the buffer support, the friction force is effectively reduced, so that the guide roller can form a relatively smooth one-way rotation, thereby ensuring the practical effect of the present invention.

[0030] The buffer support member 8 is made of rubber. The bottom side of the buffer support member 8 is fixed to the carriage body 1 , the top of the buffer support member 8 is fixed with an engineering plastic member 9 with an arc-shaped top surface, and the guide roller 7 is rotatably abutted against the top of the engineering plastic member 9 .

[0031] With the intervention of the engineering plastic part 9, the friction force is effectively reduced while ensuring the buffer support, so that the guide roller 7 can form a relatively smooth unidirectional rotation, thereby ensuring the practical effect of the present invention.

[0032] The bottom of the carriage body 1 is fixedly connected with a corresponding vehicle frame 10, through which the carriage body 1 can be flipped and installed on the rear side of the beam mechanism 12 of the mining vehicle 11. The vehicle frame 10 is flipped and driven by a corresponding hydraulic cylinder 13.
