Prying trolley

Abstract

The invention discloses a scaling rig. The scaling rig comprises a frame, a cab, a shovel, a gas-liquid mixed parking mechanism, a cab lifting pitching mechanism, a shovel translational motion mechanism, a swinging mechanism of a working device, a translational motion mechanism of a working arm and a supporting mechanism; the gas-liquid mixed parking mechanism comprises an air pump, an air storage tank, a pedal valve, a pneumatic switching valve, an oil gas brake booster pump and a wheel hydraulic brake pump; the cab lifting pitching mechanism comprises an oil cylinder accommodating cylinder and three lifting oil cylinders; the shovel translational motion mechanism comprises a first connecting rod, a second connecting rod and a translational motion driving oil cylinder; the swinging mechanism of the working device comprises a swinging supporting base, a swinging base and a swinging driving oil cylinder. According to the scaling rig, the parking operation is convenient and easy, the structural design is simple and reasonable, the material pushing of the shovel can be smooth, and the mechanical operation efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of mining machinery, more specifically to the technical field of mining trolleys. Background technique [0002] In the mining process of mines, loose stones often appear on the top and side walls of the mine after blasting during excavation. If these stones are not cleaned up in time, they will be in danger of falling off at any time. It is easy to injure the staff, thereby bringing many hidden dangers to production operations. The way that people often adopt is that the workers stand on the built shelf and use the steel braze to pry it down, which not only has a high labor intensity and low work efficiency for the workers, but also when a large area of ​​stones falls off, the workers will not be able to If it is too late to avoid, it will also bring safety hazards to the construction workers.

[0002] In the mining process of mines, loose stones often appear on the top and side walls of the mine after blasting during excavation. If these stones are not cleaned up in time, they will be in danger of falling off at any time. It is easy to injure the staff, thus bringing many hidden dangers to production operations

The way that people often adopt is that the workers stand on the built shelf and use the steel braze to pry it down, which not only has a high labor intensity and low work efficiency, but also when a large area of ​​stones falls off, the workers will not be able to If it is too late to avoid, it will also bring safety hazards to the construction workers

At present, people use a prying trolley to clean these stones that may fall off at any time, but the current prying trolley has the following deficiencies in the use process: 1. Most of its parking methods use mechanical brakes that pull the brake line. Due to the large size and heavy weight of the trolley itself, it is difficult to park the trolley stably by relying on the existing mechanical brake mechanism, especially on slopes, the existing brake mechanism has a great parking risk; 2. When the working arm is lifted to a certain height for operation, the working arm will block the operator's sight, so that the operator cannot see the position and working status of the prying brazing, which seriously affects the normal operation of the prying operation; 3. During the lifting and landing process of the shovel, the inclination angle of the shovel is constantly changing, especially during the landing operation, the pushed stones will roll down from the upper edge of the shovel and fall behind the shovel, so that It is not conducive to the cleaning of fallen stones; 4. The design of the working arm is unreasonable during work, and the rotation is not flexible enough, making it impossible to clean up many dead corners, and the work efficiency is difficult to achieve the ideal state; 5. The working arm is not flexible enough, especially When the first working arm is in motion, the heights of the second working arm and the third working arm that follow it will also move up and down, which makes it difficult for the operator to control the position of the working tool at the front end of the third working arm. The position of the most front-end working tool is controlled by adjusting the working arms step by step, which is not only very troublesome to operate, but also makes it difficult to improve the working efficiency; 6. The existing support mechanism is directly supported on the ground by hydraulic cylinders, and the hydraulic pressure The oil cylinders are fixedly installed on the frame. When parking and supporting, each hydraulic cylinder needs to be stretched out to play a role of supporting balance. Not only the parking supporting time is longer, but also the existing supporting points are located in the middle of the locomotive when it is working. The effect is not ideal
