Maintenance platform for hydraulic supports

Abstract

The invention discloses a maintenance platform for hydraulic supports. The maintenance platform comprises a working platform (1), a base (2), supporting beams (3) and a first-stage jack (4), wherein one ends of the supporting beams (3) are hinged to the base (2), the other ends of the supporting beams (3) are hinged to the working platform (1), and the two ends of the first-stage jack (4) are hinged to the base (2) and the supporting beams (3) respectively. Staff are located behind the working platform (1), the first-stage jack (4) extends out, the supporting beams (3) rotate in a vertical plane, and therefore the height of the working platform (1) can be increased, the staff can be directly transported to the preset height, the hydraulic supports can be maintained at the preset height, the staff are prevented from climbing up and down, and the personal safety of the staff is protected. According to the maintenance platform, the danger that the staff fall when climbing high for maintenance is effectively avoided, and the safety is improved.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a hydraulic support maintenance platform. Background technique [0002] In the overshoot of coal mine mining, it is necessary to set up hydraulic supports to support the mine road, and the height of the hydraulic supports is getting higher and higher. By increasing the height of the large mining height hydraulic supports, the production efficiency of the coal mine can be greatly improved. [0003] However, the increase in height also brings difficulties to the maintenance of the hydraulic support. The accessories of the hydraulic support need to be checked regularly after continuous coal mining operations, and the damaged or aging accessories must be replaced in time. However, the construction height of the maintenance work of the hydraulic support with large mining height is generally higher in the working state, and the staff also need to work at a higher position. Generally, th...

[0003] However, the increase in height also brings difficulties to the maintenance of the hydraulic support. The accessories of the hydraulic support need to be checked regularly after continuous coal mining operations, and the damaged or aging accessories should be replaced in time.

However, the construction height of the maintenance work of the hydraulic support with large mining height is generally high in the working state, and the staff also need to work at a higher position. Generally, the maintenance personnel use an escalator to fix it on the support and ascend it for maintenance, but this method exists big security risk

Or weld a working platform on the top beam of each hydraulic support, but each hydraulic support needs to be equipped with a working platform, which not only increases the manufacturing cost, but also requires maintenance personnel to use escalators to climb during the maintenance process, which also has potential safety hazards. , this method can only realize the maintenance of the fixed position, and cannot complete the maintenance of the top of the cover beam and the guard side
