Abstract
At the bottom of a kind of Bracket in Thin Coal Seam, adjust jack fixed mechanism, at the bottom of it can effectively must solve Bracket in Thin Coal Seam, regulating mechanism arrangement space is limited, the problem that fixed form is loaded down with trivial details, fixed mechanism is by backing plate, clamping plate and stationary magazine creel form, one circular hole is set on backing plate, circular hole internal diameter is more than or equal to the external diameter of end tune jack column cap, clamping plate center is with a flat hole of matching with end tune jack column cap, adjust on jack column cap with groove at the end, jagged on stationary magazine creel, the end, adjusts jack column cap the inside with fluid-through tube road, fluid-through tube road adjusts threaded liquid in-out mouth on jack column cap to communicate the end of with.At the bottom of Bracket in Thin Coal Seam, adjust jack fixed mechanism for supporting structure feature, improve innovatively the fixed form that bearing pin connects in the past, reduce jack assembly process, improve efficiency of assembling.Reduce the quantity in understructure part pin-and-hole and assembly technology hole simultaneously, greatly improved the bulk strength of understructure part.
Description
Technical field
The utility model relates to a kind of mine support plant equipment, relates in particular to and adjusts jack fixed mechanism at the bottom of a kind of Bracket in Thin Coal Seam.
Background technology
One of difficult point of the process that designs and produces of girdle, ultra-thin coal seam high inclination-angle support is: though support is little, the five internal organs are various, and structural member quantity is many, and arrangement space is little.In end regulating mechanism design, the end, adjusts the fixed form of jack conventionally to adopt bearing pin to fix at present, this fixed structure need to be on structural member expense hole and assembly technology hole, also need to design corresponding bearing pin fixed mechanism simultaneously.This is in little very limited type of arrangement space, and the difficulty of design and site operation is all very large.According to actual service condition investigation, learn, structural member perforate has very large weakening for structural parts whole intensity simultaneously, affects the whole functional performance of support.
Summary of the invention
The purpose of this utility model is to provide a kind of rational mechanism, and at the bottom of it can effectively must solve Bracket in Thin Coal Seam, regulating mechanism arrangement space is limited, the problem that fixed form is loaded down with trivial details.
For achieving the above object, the technical solution adopted in the utility model is:
At the bottom of a kind of Bracket in Thin Coal Seam, adjust jack fixed mechanism, it is characterized in that: fixed mechanism is comprised of backing plate, clamping plate and stationary magazine creel, one circular hole is set on backing plate, circular hole internal diameter is more than or equal to the external diameter of end tune jack column cap, clamping plate center is with a flat hole of matching with end tune jack column cap, with groove, jagged on stationary magazine creel on end tune jack column cap, the end, adjusts jack column cap the inside with fluid-through tube road, and fluid-through tube road adjusts threaded liquid in-out mouth on jack column cap to communicate the end of with.
According to adjusting jack fixed mechanism at the bottom of described Bracket in Thin Coal Seam, it is characterized in that: the described end adjusts jack column cap tail end section to be shaped as the circular oblateness that is cut out a part and obtain.
This fixed mechanism adjusts jack column cap to coordinate by fixing hole and the end.Column cap is vertically inserted to fixing hole along stationary magazine creel, by column cap 90-degree rotation, complete the fixedly action of adjusting jack in the end, then insert threaded connector, when meeting feed flow, also play the effect that prevents column cap rotation slippage.This fixed mechanism is removed same simple easy operating, according to packing order into, oppositely can complete dismounting work, convenient and swift.
At the bottom of Bracket in Thin Coal Seam, adjust jack fixed mechanism for supporting structure feature, improve innovatively the fixed form that bearing pin connects in the past, reduce jack assembly process, improve efficiency of assembling.Reduce the quantity in understructure part pin-and-hole and assembly technology hole simultaneously, greatly improved the bulk strength of understructure part.Both guarantee Bracket in Thin Coal Seam compact conformation, and for other structural member of support, arranged the space being more imbued with is provided, improved again the bulk strength of structural member simultaneously, improved the on-the-spot functional performance of support.
The utility model can be widely used in the structure design of girdle, ultra-thin coal seam support, and the jack fixed form for other operating position has reference simultaneously.
Accompanying drawing explanation
Fig. 1 adjusts jack fixed mechanism schematic diagram the end.
Fig. 2 is for having assembled back part relative position schematic diagram.
In accompanying drawing: 1, backing plate; 2, clamping plate; 3, stationary magazine creel; 4, jack column cap is adjusted at the end; 5, logical liquid threaded connector; 6, breach; 7, groove.
The specific embodiment
Embodiment
For the ease of show internal structure, Fig. 1-2 shown in stationary magazine creel 3 adopt partial sectional views, breach 6 is to be positioned at the flat round hole that logical liquid threaded connector 5 is convenient to install in top.
At the bottom of Bracket in Thin Coal Seam, adjust a jack fixed mechanism, as shown in Figure 1, this fixed mechanism is arranged in Bracket in Thin Coal Seam base one side according to work plane incline direction, for regulating the distance between support.As shown in Figure 1, fixed mechanism is comprised of backing plate 1, clamping plate 2 and stationary magazine creel 3 three parts, and fixed mechanism is by adjusting jack column cap 4 to coordinate the end to adjust the fixing action of jack the end of with.As shown in Figure 1, flat hole by column cap 4 along the vertical insertion clamping plate 2 of stationary magazine creel 3, again adjusted to jack column cap 4 90-degree rotations the end, complete the fixedly action of adjusting jack in the end, insert again logical liquid threaded connector 5, when meeting for end tune jack feed flow, also play the effect that prevents column cap rotation slippage.This fixed mechanism is removed same simple easy operating, according to packing order into, oppositely can complete dismounting work, convenient and swift.
