Description
Technical field
The utility model relates to a kind of coal mine roadway support equipment, relates to a kind of laneway temporary support hydraulic pressure sectional shelf-unit specifically, belongs to the colliery tunnel support equipment technical field.
Background technology
At present at coal industry, in the recovery process for mine, raising along with tunnelling speed and drivage efficiency, the tunnel of driving is before the tunnel that forms permanent support, must take to set up temporary lining, to guarantee that garden-fresh tunnel is before finishing permanent supporting, absciss layer, distortion, roof fall can not appear in back, especially in big gun pick roadway construction, because the force of explosion of blowing out produces great destructive power to country rock, balkstone integrality destruction, fragmented rock are dropped easily, construction operation personnel's life security is on the hazard.In the operating regulation of colliery, stipulate: before digging laneway is finished permanent support, must in time take measures, set up temporary lining, can not collapse, threaten construction operation personnel's life to guarantee the tunnel.The digging laneway of prior art is with in the temporary support device; because the too simple supporting intensity of device is low; can not have the protection of reliability to the tunnel, and can not satisfy big gun pick tunnel and machine pick tunnel with pick with the requirement of temporary lining, bring hidden danger to safety in production.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of laneway temporary support hydraulic pressure sectional shelf-unit is provided, it comprises two hydraulic props that have base, outstanding column is passed oil cylinder on having between two hydraulic props, go up outstanding column and pass the support fixing anchor bar that penetrable top board is arranged on the oil cylinder, holder is arranged on the hydraulic prop, holder is connected with by bearing pin the forestope of visiting the beam push cylinder is housed, expansion link is arranged on the forestope, also has bottom bracket on the holder, bottom bracket is connected with forestope by connecting rod, and the beam of spy stretching oil cylinder is arranged between holder and the bottom bracket, and a side of hydraulic prop has the diagonal brace jack to be connected with bottom bracket.This hydraulic pressure sectional shelf-unit both can be used for big gun pick tunnel drive hoeing machine muck, hydromucker muck, can be used for combining pick tunnel mechanized construction again.When the roadway repairing construction operation, it can also prevent the inbreak of back fragmented rock, and injure the constructor by a crashing object effectively as blindage simultaneously.Simultaneously do not influence the supporting operation, can finish anchor pole, cable bolting and the shed shoring in tunnel.
The utility model is realized with following technical scheme: a kind of laneway temporary support hydraulic pressure sectional shelf-unit, it comprises two hydraulic props that have base, it is characterized in that: between two hydraulic props, have column to pass oil cylinder, below the column passing oil cylinder collapsible slip ring is arranged, column is passed the support fixing anchor bar that penetrable top board is arranged on the oil cylinder, holder is arranged on the hydraulic prop, holder is connected with by bearing pin the forestope of visiting the beam push cylinder is housed, expansion link is arranged on the forestope, also has bottom bracket on the holder, bottom bracket is connected with forestope by connecting rod, the beam of spy stretching oil cylinder is arranged between holder and the bottom bracket, and a side of hydraulic prop has the diagonal brace jack to be connected with bottom bracket.
Have column to pass oil cylinder between described hydraulic prop and the hydraulic prop, column is passed has collapsible slip ring below the oil cylinder, and column is passed the support fixing anchor bar that penetrable top board is arranged on the oil cylinder, and crossbeam is arranged on the hydraulic prop.
The utility model has the advantages that: this hydraulic pressure combination rack structure is simple, and disassembly process is quick.It both can be used for big gun pick tunnel drive hoeing machine muck, hydromucker muck, can be used for combining pick tunnel mechanized construction again.When the roadway repairing construction operation, it can also prevent the inbreak of back fragmented rock, and injure the constructor by a crashing object effectively as blindage simultaneously.Simultaneously do not influence the supporting operation, can finish anchor pole, cable bolting and the shed shoring in tunnel.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Accompanying drawing is the utility model structural representation:
Among the figure: 1,2, hydraulic prop, 3, collapsible slip ring, 4, upward outstanding column is passed oil cylinder, 5, support fixing anchor bar, 6, the diagonal brace jack, 7, holder, 8, visit beam stretching oil cylinder, 9, bottom bracket, 10, on visit the beam push cylinder, 11, forestope, 12, expansion link, 13, the chain extension bar, 14, bearing pin, 15, crossbeam, 16, base.
The specific embodiment
As shown in the figure: a kind of laneway temporary support hydraulic pressure sectional shelf-unit, it comprises hydraulic prop 1 and the hydraulic prop 2 that has base 16, outstanding column is passed oil cylinder 4 on having between hydraulic prop 1 and the hydraulic prop 2, below the column passing oil cylinder collapsible slip ring 3 is arranged, column is passed the support fixing anchor bar 5 that penetrable top board is arranged on the oil cylinder, holder 7 is arranged on the hydraulic prop 2, holder is connected with by bearing pin 14 forestope 11 of visiting beam push cylinder 10 is housed, expansion link 12 is arranged on the forestope, also has bottom bracket 9 on the holder, bottom bracket is connected with forestope 11 by connecting rod 13, the beam of spy stretching oil cylinder 8 is arranged between holder 7 and the bottom bracket 9, and a side of hydraulic prop 2 has diagonal brace jack 6 to be connected with bottom bracket 9.
Have between described hydraulic prop 1 and the hydraulic prop 2 and go up outstanding column and pass oil cylinder 4, upward outstanding column is passed has collapsible slip ring 3 below the oil cylinder, and upward outstanding column is passed the support fixing anchor bar 5 that penetrable top board is arranged on the oil cylinder, and crossbeam 15 is arranged on the hydraulic prop.
The course of work: in the big gun pick, when combining the pick construction operation, forestope 11 upwards spurs bottom bracket 9, upwards turns to vertical and position hydraulic prop 1,2 for 90 ° by the vertical position parallel with hydraulic prop 1,2 of forestope 11 by stretching oil cylinder 8, the diagonal brace jack 6 that is connected by bottom bracket is flexible again, visits the supporting role of frame to top board before support force is reached.In the installation of finishing tunnel lapping, anchor shaft anchor cable, after reaching the permanent support effect, earlier to hydraulic prop 1 release, last spy beam push cylinder 10 is shunk, make hydraulic prop 1 be advanced to the snap ring position, hydraulic prop 1 boosts then, after reaching working resistance, again to forestope 11 by stretching oil cylinder 8 promote lower supporting rods 9 downwards, by forestope 11, by parallel with the hydraulic prop 2 downwards position of 90 ° of horizontal directions, hydraulic prop 2 releases, the outstanding oil cylinder 4 of passing in the operation, outstanding oil cylinder reach 4 in the passing, shift hydraulic prop 2 onto and pass forward, thereby finish a working cycles.
