Abstract
The utility model relates to an improvement on support devices used on extracting faces in coal mines, which is suitable for roof caving extracting faces. The utility model adopts a sectional type top beam of a support frame, each section of the top beam of a support frame is connected by using connecting blocks, and the sectional beams and the connecting blocks can make relative rotation through a support pin and a spacing pin to be well adapted to the variation of the top plate at a front head. When stressed, the top beam of a support frame can only be in a camber shape, so that the top beam of a support frame can be prevented from deformation to avoid jam and blockage. The utility model can bring convenience to the underground transportation and the installation.
Description
The utility model relates to the improvement of stope support apparatus under the coal mine, is applicable to the caving coal mining work plane.
When top coal caving, the rear portion conveyer is positioned under the caving shield, is in beyond the back timber break line, dote on big head and occupied very large space, and roof pressure is the most complicated herein, causes big difficulty to the supporting at this place.In existing suspended back timber, sliding type cap for supporting mine roof top-coal caving face, two modes are mostly adopted in the supporting at head position, and a kind of is that individual prop is joined long beam employing " four legs, eight beams " form, and a kind of is to finish for the bigger transition bracket of such support equipped.Preceding a kind of " four legs, eight beams " formula labour intensity is big, poor stability, and this place's coal recovery is low, and makes a work plane have two kinds of support forms, unfavorable mine standardized management; Adopt transition bracket, though be the trend of mine development, in existing transition bracket, back timber is oversize, and very easily flexural deformation under the roof pressure effect of complexity has hindered the preceding shifting movement of support.Simultaneously, the back timber that transition bracket is long also brings great inconvenience to down-hole transportation, installation.
The purpose of this utility model is to improve the agent structure of the transition bracket in the top-coal caving face, avoids the flexural deformation that produced when using the transition back timber, make the supporting of head district rationally, convenient, safety, flexibly and can improve coal yield.
The utility model is from changing the stressed of transition back timber, with the excessively bridging beam recombinant of hinged mode with segmentation.The concrete measure that adopts is set cap is divided into the plurality of segments beam, during use again by link block with segmentation beam composite joint one, the pin-and-hole of support and limit pin hole are arranged on the contiguous block, the support pin-and-hole is a circular hole, limit pin hole is a slotted hole that certain curvature is arranged, wherein there are a support pin-and-hole and limit pin hole to be positioned at homonymy, and support the pin-and-hole design on limit pin hole.Contiguous block one end and a segmentation beam are carried out and are rigidly connected, and they pass the support pin-and-hole with supporting pin and realize; Contiguous block is then to use supporting pin and spacer pin that the two is hinged with an end and another segmentation beam.The supporting pin and the spacer pin that are positioned at the contiguous block homonymy can make the contiguous block and the segmentation beam that are hinged on one time spent can do relatively rotating stressed the work, and this rotation can only be undertaken by the curvature of limit pin hole.The entire bracket back timber can only be presented arch shape when segmentation beam contiguous block relative position changed like this.Thereby improved the force structure of back timber, can adapt to head place top board and change, avoided the back timber distortion that jam takes place, more be adapted to the transportation and the installation of down-hole.
Further set forth the utility model in conjunction with Figure of description:
(1) and (6) is the segmentation beam among the figure, (4) be contiguous block, (2), (5), (7) are supporting pin, (3) be spacer pin, three support pin-and-holes and limit pin hole, contiguous block (4) right-hand member and a segmentation beam (6) are arranged by passing two supporting pin (5), (7) of supporting pin-and-holes on the utility model contiguous block, realization is rigidly connected, contiguous block (4) left end links to each other with segmentation beam (1), and they are that contiguous block (4) left upper end supports the supporting pin (2) of pin-and-hole and the spacer pin (3) of lower-left end limit pin hole is realized hinged with passing.Because limit pin hole is a curve slotted hole, spacer pin (3) runs through segmentation beam (1) and contiguous block (4), be subjected to the time spent of doing of top board power when set cap, segmentation beam (1) and contiguous block (4) can change relative position, segmentation beam (1) with supporting pin (2) center be the center along angle of limit pin hole variable curvatureization, the result can only present arch shape by contiguous block (4) with the entire bracket back timber that segmentation beam (1) and segmentation beam (6) are tied.
The utility model adopts the segmented set cap, can adapt to head place top board preferably and change, and when set cap is stressed, can only present arch shape, has improved force-bearing situation, has avoided the upper frame distortion, and jam takes place, and it is very convenient that the down-hole is transported, installed.
