Background
In the development process of coal mining mechanization, the hydraulic support for top coal caving is important mechanical equipment for realizing coal mining, transportation and supporting of modern coal mines, is not only used for supporting a working face top plate, but also closely associated with coal mining transportation equipment, and has significance in lifting weight in coal mining work. However, when the hydraulic support for caving the top coal is used, the upright posts of the hydraulic support can cause damage to the sealing elements under the pressure action of the top plate, so that liquid leakage at the cylinder opening is caused. When the hydraulic support is overhauled, the nut on the upright cylinder body needs to be unscrewed, the sealing element is replaced, but no professional upright overhauling assembly exists at present, and the nut cannot be disassembled by fixing the upright, so that the hydraulic support for caving coal is very difficult to overhaul after the hydraulic support fails.
SUMMERY OF THE UTILITY MODEL
The utility model provides an overhaul subassembly of caving coal hydraulic support stand, aim at solve current caving coal hydraulic support's stand can cause the sealing member to damage under roof pressure and lead to the jar mouth weeping, nevertheless does not have professional stand and overhauls the subassembly, leads to the stand to break down the back and overhauls very difficult problem.
The utility model relates to an overhaul assembly of a hydraulic support upright post for caving coal, which comprises an overhaul platform, wherein the overhaul platform is of a three-dimensional frame structure and comprises fixing seats arranged in parallel, and two symmetrical baffle plates are vertically arranged on the fixing seats; the top of the maintenance platform is provided with a crossbeam, a tail beam jack is vertically arranged on the crossbeam, and a telescopic beam jack and a side protection jack are sequentially arranged on a doorframe at the side edge of the maintenance platform from top to bottom; the tail beam jack, the telescopic beam jack and the side protection jack are controlled by a control valve, and the control valve provides power through an emulsion pump; the maintenance assembly further comprises a hollow round special spanner, the inner ring of the special spanner is symmetrically provided with buckles, and the special spanner is provided with a plurality of jack connecting holes at equal intervals on the surface.
Preferably, the distance between the two baffles is matched with the outside size of the upright post.
Preferably, the size of the buckle is matched with that of the groove of the nut on the upright post.
Compared with the prior art, the beneficial effects of the utility model are as follows:
1. the utility model provides an overhaul assembly for putting on top coal hydraulic support stand, be equipped with special spanner, the tail-beam is very heavy, flexible roof beam is very heavy and the side protects very well, it is fixed with the stand earlier with the fixing base, reuse tail-beam jack tight stand, when unscrewing the nut, only need insert the stand upper nut recess with special spanner buckle, the jack connecting hole rigid coupling of the very heavy and side protection of flexible roof beam and special spanner again, last operation control valve jacks tightly, flexible roof beam is very heavy and the side protects very heavy meeting with pressure action special spanner, can easily unscrew the nut behind the special spanner atress, this method labour saving and time saving, the nut is difficult to unscrew after having solved the stand and breaking down, overhaul difficult problem, the work efficiency is greatly improved.
2. The utility model provides an overhaul assembly for caving coal hydraulic support stand wholly adopts the I-steel repacking to form, has reached the purpose of repairing old and useless, greatly reduced manufacturing cost, alleviateed staff's intensity of labour, avoided the potential safety hazard that high-pressure liquid wounded the people.
