Unpowered slag unloading trolley

Abstract

The invention discloses an unpowered slag unloading trolley. The slag unloading trolley comprises a trolley body, a trolley door and wheels, and the trolley door and the wheels are arranged on the trolley body. The trolley body is provided with a trolley upper bottom face and a trolley lower bottom face, and a counterweight layer is arranged between the trolley upper bottom face and the trolley lower bottom face. A trolley front side face and a trolley rear side face are arranged at the two ends of the trolley body in parallel. The included angle between the trolley upper bottom face and the trolley lower bottom face, the included angle between the trolley front side face and the vertical direction and the included angle between the trolley rear side face and the vertical direction are equal to the included angle between an inclined shaft and the horizontal plane. The trolley door is arranged on the trolley front side face and is hinged to and connected with the front side face. When the unpowered slag unloading trolley runs in the inclined shaft, the four side faces are kept in the vertical state, and running safety and stability of the trolley are improved; a slag unloading platform on the opening of the inclined shaft is arranged as a slope, and the angle of the slope is smaller than that of the inclined shaft; during slag loading, after the trolley door is opened, slag can automatically slide out from the trolley; after the slag is unloaded, the trolley can automatically move backward by means of gravity of the trolley and counterweights, and the trolley can conveniently enter the preparation state for next time of work without power.

Description

technical field [0001] The invention relates to slag discharging equipment for large-angle inclined shafts, in particular to a non-powered slag unloading trolley. Background technique [0002] At present, the slope of the large-angle construction inclined shaft in the project is generally less than 25 degrees. For the inclined shaft with a slope greater than 25 degrees, the slag discharge method is mainly rail slag discharge. [0003] Chinese patent application CN 103362546 A proposes that in the transportation construction of an inclined shaft with a steep slope, a rail material transport device is used to enable the dump truck to smoothly enter and exit the construction area to carry out slag discharge. However, in the bridge foundation project, the excavation length of the inclined shaft is relatively short, and the use of rail transportation to discharge slag not only greatly increases the investment in construction equipment, but also has complicated rail transportation...

AI Technical Summary

Problems solved by technology

However, in the bridge foundation project, the excavation length of the inclined shaft is relatively short, and the use of rail transportation to discharge slag not only greatly increases the investment in construction equipment, but also has complicated rail transportation auxiliary facilities and a large number of auxiliary construction workers. Extended construction period to some extent
