Transportation method for special end supports with two supports as one group

Abstract

The invention discloses a transportation method for special end supports with two supports as one group, and belongs to the technical field of underground hydraulic support transportation. According to the method, a transportation scheme that the front, middle and rear groups of supports are split and then are subjected to bilateral symmetry and grouping combination is adopted, namely, the supports are lowered to the optimal transportation positions to be transported from front to back and from top to bottom in a fixed transportation mode of a front top beam, a front base, a middle top beam, a middle base, a rear top beam and a rear base of the supports. Therefore, on one hand, the problem that the supports are poor in stability in the transportation process due to the fact that the width of the supports is small is solved, on the other hand, the supports are transported to a working face in the sequence of back-middle-front, assembly can be completed only by hinging corresponding top beams and base bolts, and convenience and rapidness are achieved.

Description

technical field [0001] The invention belongs to the technical field of coal mine production, in particular to the technical field of underground transportation, in particular to a transportation method for two sets of special end brackets. Background technique [0002] With the rapid development of coal mining technology and coal mining equipment, there are more and more supporting equipment at the head and tail of the underground coal mining face. With the development, the application of two sets of special end brackets instead of traditional single columns for support at the nose and tail is becoming more and more widely used. [0003] A set of two special end brackets consists of front, middle and rear bracket groups, and each bracket group is composed of left and right single brackets, that is, a total of six single brackets, with a total length of about 20m , The width of a single frame is about 600mm-800mm. "Two sets of special end brackets" can be arranged on both s...

AI Technical Summary

Problems solved by technology

However, because of its long structure and narrow width, it brings difficulties in transportation, especially the transportation of the whole frame is extremely difficult, so the current method is to disassemble and transport it, that is, after it is completely disassembled, disassemble the top beam, Columns, cover beams, four-links and other mechanisms are transported independently, but after they are transported underground, they will be limited by installation space and lifting equipment, making assembly very difficult, and it is basically impossible to complete the assembly task within the specified construction period

According to research, at present, the transportation of such supports in major mines in China adopts the method of dismantling and transporting underground and reassembling underground, which takes a long time and is extremely dangerous. There is no other good solution
