Long-distance armless mine-raking trolley

Abstract

The invention discloses a long-distance armless mine-raking trolley which comprises a trolley body and a walking mechanism arranged below the trolley body. The walking mechanism is mainly composed of a trolley body chassis, a rear axle, tires and a transmission shaft which are responsible for trolley walk. The front portion and the tail portion of the trolley body chassis are provided with a middle frog-type hydraulic supporting leg and a tail frog-type hydraulic supporting leg respectively. A power and operation system is mounted on the front portion of the trolley body. A scraper winch and a vehicle-mounted crane are mounted on the trolley body chassis. The scraper winch is connected with the trolley body chassis through a rotary shaft disk. The rotary shaft disk is provided with a shaft disk rotating shaft used for being connected with a scraper winch base. According to the long-distance armless mine-raking trolley, a common scraper is loaded onto the trolley body, two fixed pulleys arranged in a field move in cooperation with the mine-raking trolley, and then large-area mechanical mine raking and united ore withdrawal operation in cooperation with a scooptram are achieved; the long-distance armless mine-raking trolley solves the technical problems that when a traditional method is used, the mine raking position is fixed, carrying is difficult, the ore withdrawal efficiency is low, the depletion loss rate is large, operation safety is poor, and cost is high.

Description

technical field [0001] The invention relates to a long-distance armless rake trolley, which is mainly suitable for collecting and transporting ore falling from a gently inclined floor, and is especially suitable for mining with trackless equipment, where the roof of the stope is unstable and the structural parameters of the mine house are relatively large. Underground metal or non-metal mines that are large, difficult for personnel and equipment to enter, and have poor stope safety conditions. Background technique [0002] The ore transportation during the mining of gently inclined ore bodies has always been a technical problem at home and abroad. Due to the influence of the thickness and inclination of the ore body, the ore that collapses in the gently inclined ore body cannot rely on gravity for ore drawing. If the bottom structure is arranged at the footwall of the ore body, the amount of mining work will be large and the mining cost will be high. Therefore, the traditio...

AI Technical Summary

Problems solved by technology

As far as the mining method is concerned, the method of throwing blasting is widely used to throw ore into the ore collection chute. Although this method has a certain effect on the transportation of ore on the gently inclined floor, it is complicated in technology and difficult in construction. In most cases, blasting can not achieve the desired effect

As far as mining equipment is concerned, crawler excavators are often used to directly enter the stope to process floor ore. Although the flexibility of equipment, labor intensity of workers, and ore loss rate have been solved, the auxiliary workload is large. , The problems of poor operation safety and low efficiency have not been solved, especially when the stability of the stope roof rock layer is poor, and the ground pressure of the roadway is high and maintenance is difficult, which often leads to major safety accidents involving vehicle crashes and fatalities. Hidden danger

[0004] With the widespread adoption of trackless equipment, efficient, safe, and low-labor-intensity advanced equipment and techniques are gradually accepted by mines. Outdated production equipment and techniques like traditional electric rakes are severely challenged. There is no market for mining that relies on a lot of manpower and material resources.
