Mobile lift maintenance platform for underground coal mine

Abstract

The invention relates to a mobile lifting overhauling platform in an underground coal mine. A heavier or bigger article can be lifted directly by the mobile lifting overhauling platform, without the need of an external device, and a device needing to be mounted is directly mounted, so that other transportation costs are reduced; the mobile lifting overhauling platform is convenient to operate, maintenance places can be changed any time any where, and an additional device for auxiliary operation is not needed; oil cylinders on two sides can be controlled independently, so that the stability is improved, and the life safety of maintenance personnel is ensured well; a hydraulic lock is automatically opened during the ascending and descending process, but the hydraulic lock is automatically locked during the on-site maintenance process of the maintenance personnel; and even if a vehicle is broken down or oil leaks from a pipeline, a lifting platform is also kept at the original position, so that the safety coefficients are further increased. After the lifting platform is broken down, ground personnel can control a manual pump to realize the stable descending of the lifting platform, so as to ensure the safety of the maintenance personnel on the lifting platform and transfer vehicles for maintenance.

Description

technical field [0001] The invention relates to a movable lifting and maintenance platform for coal mine underground, which is used for operation and maintenance at the top of the coal mine underground roadway. Background technique [0002] In the coal mining industry, scaffolding or hydraulic lifting platforms must be used for high-altitude operations on the top of underground roadways, but the previous high-altitude operations at the top of underground mines have the following defects: [0003] 1. In the past, the underground high-altitude operation can only be carried out at a certain fixed position for lifting operation. If the operation needs to be changed to another location, the operation platform needs to be erected again, and the same steps are repeated, which is time-consuming and labor-intensive. [0004] 2. In the past, explosion-proof electric or special hydraulic platforms used in underground high-altitude operations needed to choose external power sources, wh...

Problems solved by technology

If the operation needs to be changed to another location, the operation platform needs to be erected again, and the same steps are repeated, which is time-consuming and labor-intensive

[0004] 2. In the past, explosion-proof electric or special hydraulic platforms used in underground high-altitude operations needed to choose external power sources, while coal mine underground power sources needed to have one every few hundred meters or thousands of meters, and special hydraulic power sources needed other It can only be used with the cooperation of hydraulic equipment, which is extremely inconvenient to operate

[0005] 3. In the past, the underground aerial work platform needs to be manually transported to the designated operating location. The underground pits of the coal mine are uneven, which increases the labor intensity of the coal mine personnel and the efficiency is very low.

[0006] 4. The carrying capacity of the previous underground aerial work platform can only have one operator to work

thus adding additional shipping costs
