Vertical lifting and conveying system for open-pit mine trucks

Abstract

The invention discloses a vertical lifting and conveying system for open-pit mine trucks, comprising a vertical I-beam rail, a horizontal T-beam and a top plate. The horizontal T-beam is horizontally disposed on rock walls on two sides. The vertical I-beam rail is vertically connected with the horizontal T-beam. The top plate is disposed at the top end of the vertical I-beam rail. A lifting container is slidably connected with the vertical I-beam rail. A head sheave is disposed on the upper surface of the top plate. One end of a wire rope is connected with a lift, and the other end passes the head sheave and a tension balancer and is connected with the lifting container. Brakes are disposed on the left and right sides of a parking platform of the lifting container. The vertical lifting and conveying system has the advantages that adaptability of the truck lifting and conveying method is improved, conveying range and time of the trucks is greatly shortened, conveying efficiency is improved, truck conveying cost is saved, exhaust emission is reduced, and conveying safety and reliability is improved.

Description

technical field [0001] The invention relates to a lifting transportation system, in particular to a vertical lifting transportation system for a whole vehicle of an open-pit mining vehicle. Background technique [0002] Surface mine transportation system is the core part of surface mining. Most of the existing open-pit mines are transported by mine trucks along the winding mountain roads in the mining area. This mode of transport has a wide range of applications, and the vehicles are flexible and easy to transport. High, low transportation efficiency, serious pollution to the environment of the mining area, restricting the development of mining truck transportation in large deep concave open-pit mines. With the increase of the annual mining volume of open-pit mines, it is necessary to improve the transportation efficiency of open-pit mines and adopt economical and efficient open-pit mine transportation methods. [0003] The proposal of the lifting transportation mode of th...

Problems solved by technology

[0004] However, the lifting transportation method proposed by the above-mentioned patent is limited to the mining vehicle only lifting along the steep slope. This method of lifting the whole vehicle on a steep slope has limited increase in slope. As the depth of the stope increases, the applicability of this transportation method becomes more and more The worse it is, the transportation capacity and efficiency will be difficult to greatly improve; the driving power for lifting comes from the mining vehicle itself, which requires higher power performance of the mining vehicle, and in the process of lifting, not only the self-weight of the mining vehicle must be overcome, but also the The resistance of the transmission system and the excessive load of the vehicle will increase the wear and tear of the mining vehicle and reduce the life of the vehicle; the lifting operation is controlled by the driver of the mining vehicle, so there are too many human factors and the reliability is not high
