Abstract

The utility model relates to a single-base multi-beam hydraulic bracket used for the work surfaces of mines. A plurality of narrow top beams are arranged on an integrated base and an upright post in parallel. Beam connecting devices connect various beams into a whole and ensure the mutual staggering and deflection, thereby improving the top connection. The adoption of the integrated base can ensure that the bracket has relatively high rigidity and stability, meanwhile can reduce the floor specific pressure and prevent the floor gnawing. A bracket body structure is composed of the base, the top beam, the beam connecting devices, a stabilizing mechanism, and an upright post, and is formed by the connection of the base, the top beam, the beam connecting devices, the stabilizing mechanism, and the upright post. The bracket body structure has four types, namely, a double-row-post four-connecting-rod type, a single-row-post four-connecting-rod type, a double-row-post single-swing-stem type and a double-row-post vertical-guide-rod type. The four types can create four varied types of multi-beam hydraulic brackets. The bracket not only maintains the characteristics of high rigidity, integration, good stability and fast bracket movement of integrated exploration bracket but also has the characteristics of lightness, convenient package and conveyance, strong applicability and flexible use of a simple bracket. The bracket can be applied to support the work surfaces of integrated exploration and explosive exploration in medium and small mines.

Description

Many beams hydraulic support of single end

Technical field

The utility model relates to many beams hydraulic support of single end that a kind of colliery underground mining work plane uses.

Background technology

At present, domestic the most frequently used comprehensive mining hydraulic bracket mainly contains four link type hydraulic supports and single wobbling pole type hydraulic support.They all belong to the large-scale integral hydraulic support, have the intensity height, and the characteristics of globality and good stability are applicable to the higher fully-mechanized mining working of efficient and intelligent degree.China has the colliery now, medium and small colliery One's name is legion, and general production, transportation, hoisting power are not high, and the weight of large-scale fully mechanized mining supporter is big, cost an arm and a leg, general medium and small client is difficult to bear economically, also is difficult to give full play to its production efficiency even if use the down-hole.In recent years, hydraulic prop for sliding mine caps develops to some extent in some places, this class support is not generally established base, effectively do not connect between the adjacent frame, they link together left and right sides back timber by specific slipping mechanism in frame, the mutual changing of the relative positions of right back timber of keeping left realizes moving frame, exists top-heavyly, and it is serious to insert the end, self stability is poor, move frame and transfer the frame difficulty, operation technique is difficult for problems such as grasp, particularly in use, when frame takes place a support, be easy to cause adjacent frame and fall frame, form chain reaction, ordinary production and personal security are constituted a serious threat.In this case, research and develop a kind of safe, good integrity, easy to operate, compliance is strong, volume is little, and is in light weight, is convenient to transport the light hydraulic support of installation, has important practical significance.

Summary of the invention

The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of many beams hydraulic support of single end of mainly being made up of an integral rigidity base, a plurality of back timber between comprehensive mining hydraulic bracket and hydraulic prop for sliding mine caps is provided.This support both had been applicable to fully-mechanized mining working, kept that fully mechanized mining supporter intensity height, supporting intensity are big, the characteristics of good stability, be applicable to blast mining face again, have in light weight, good integrity, shipment is convenient, compliance is strong, use flexible characteristic, thereby can solve the problem that the middle and small scale coal mine support technology falls behind.

The purpose of this utility model can realize by following technical measures:

Many beams hydraulic support of a kind of single end mainly is made up of linkage, stabilizing mechanism, column etc. between base, back timber, beam.

Above an integral rigidity base, be provided with a plurality of narrow type back timbers, the T type gathering sill of several verticals before and after the side of each back timber is provided with, contiguous block cooperates with T type gathering sill adjacent beams is fused between i-shaped beams, and linkage between the formation beam, this device can guarantee the mutual changing of the relative positions and the deflection of each back timber in the support fore-and-aft plane, can improve the adaptive capacity of back timber to top board greatly; Corresponding with back timber, caving shield also all is made up of the identical separate part of a plurality of structures with the rod member that constitutes the support stabilizing mechanism.

A plurality of needlings are set in that the integral rigidity base is corresponding with back timber, are connected with each back timber with bearing pin with ball pivot by column respectively.Between the base main gusset, be provided with guide groove, be used for the moving movement of the special push rod that is installed on it is play the guiding role.

The beneficial effects of the utility model are:

1 one supports adopt a plurality of not only having connected each other but also the narrow type back timber of the changing of the relative positions and deflection mutually, and back timber is greatly increased to the adaptive capacity of top board, can safeguard top board better;

More than 2 back timber is connected with the integral rigidity base by tail boom, connecting rod, and the globality of support and self stability are guaranteed, avoided simple rack to insert the end, the problem of frame and moving difficulty, and advancing velocity can be close with integral support;

3 each narrow type back timber, caving shield and bar linkage structure be simple, in light weight, easy to process, be convenient to shipment.

In a word, these many boom supports integrate the advantage of fully mechanized mining supporter and slippage bracket, simple in structure, combined and instant, in light weight, intensity is high, stability is strong, is convenient to adorn, tears open, operates industry, can be used for that machine is adopted, big gun is adopted, the caving coal mining work plane, have excellent popularization prospect and using value.
