Abstract
The utility model discloses a monomer vertical temporary supporting device for the temporary supporting of heading face in underground mines, which comprises a monomer hydraulic prop (2), a top beam (1) and so on; wherein, the appropriate position in the middle if the top beam (1) is hinged connected with the piston rod top of the monomer hydraulic prop (2); the pressure of the monomer hydraulic prop (2) is provided by the underground hydraulic station (5) or light emulsion pump. The utility model has the advantages of simple structure, user-friendliness, fast and safe operation for temporary supporting, wide applicability for tunneling frontal geology, labor-saving, and so on.
Description
One, affiliated technical field
The utility model is the device that a kind of mine down-hole driving face carries out temporary lining, and the comprehensive driving face of comprehensive mechanization carries out the monomer column temporary support device of temporary lining under specifically a kind of coal mine.
Two, background technology
At present, the form of forestope is all adopted in the temporary lining of driving face under the coal mine, promptly earlier forestope (steel pipe of promptly being furnished with suspension ring) is suspended on the threaded anchor rod exposed parts of back, after fully-mechanized digging machine has cut row's (being about 0.8m), the segment distance of dropping back, be used for temporary lining, the top board wire lath, the steel band that lay are provoked, the steel pipe of reach forestope is held the top board wire lath again, steel band, with square wood strip add real add the jail after, set top board and both sides anchor pole, again control beam one segment distance before the recession, so that fully-mechanized digging machine tunnels, so circulation.Therefore, adopt forestope to carry out temporary lining, exist following shortcoming: 1, a circulation forestope will move twice, and will the side's of installing wood strip, supporting inconvenience, time-consuming taking a lot of work; 2, since forestope be suspended in roofbolt under the position, thereby influenced setting of roofbolt; When 3, driving face chance special geologic condition caused the top board out-of-flatness, owing to be subjected to the suspension ring effect length, forestope can't use, thereby can't guarantee safety in production.
Three, summary of the invention
The purpose of this utility model is that the temporary lining for mine down-hole driving face provides a kind of simple in structure, easy to use, temporary lining operation quick and safe, is suitable for the individual prop formula temporary support device that the boring head geological conditions is wide, save manpower.
The technical scheme that the utility model is taked is: be made up of hydraulic prop, back timber etc.The appropriate position at back timber middle part and the piston rod top hinge-coupled of hydraulic prop, hydraulic prop can be communicated with the underground hydraulic pressure station, when when Hydraulic Station is far away, when being equipped with light-duty emulsification pump etc., provides pressure by Hydraulic Station or light-duty emulsification pump.
When using the utility model to carry out temporary lining, when fully-mechanized digging machine has cut a circulation (a section is a row 3.6m) fully-mechanized digging machine is withdrawed from, with the position discharging in accordance with regulations of a plurality of the utility model, the top board wire lath that lays, steel band is placed on the back timber of the present utility model, operating hydraulically operated station or light-duty emulsification pump, by hydraulic prop with the top board wire lath on back timber and the back timber, steel band jack-up, just can carry out temporary lining, after setting up permanent support, only need operating hydraulically operated station or light-duty emulsification pump, fall back timber, the utility model just can be used for temporary lining next time.
Since the Temporary Support Design that the utility model is a down-hole pick halberd makes face a monomer column temporary support device, make the supporting operation quick, back timber of the present utility model and hydraulic prop hinge-coupled, still can when the end face out-of-flatness, use, the utility model can discharge according to the needs of temporary lining face, just do not influence the setting of roofbolt yet, do not influence the digging of propelling once more of fully-mechanized digging machine yet, therefore, the utlity model has simple in structure, easy to use, temporary lining operation quick and safe, the boring head geological conditions that is suitable for is wide, saves characteristics such as manpower.
Four, description of drawings
Accompanying drawing is the utility model schematic diagram.
Five, specific implementation method
As shown in the figure, the utility model is made up of hydraulic prop 2, back timber 1 etc., and the appropriate location at back timber 1 middle part is hinged on the piston rod top of hydraulic prop 2; Hydraulic prop 2 can be communicated with underground hydraulic pressure station 5, also can be communicated with light-duty emulsification pump, provides pressure liquid (generally adopting emulsion) by Hydraulic Station 5 or light-duty emulsification pump
When using the utility model to carry out temporary lining, after fully-mechanized digging machine has cut a row, fully-mechanized digging machine was both withdrawed from, the utility model is discharged on request, the top board wire lath, the steel band that lay are placed on the back timber 1, operating hydraulically operated station 5 (or light-duty emulsification pump), pass through back timbers 1 with top board wire lath, steel band jack-up by hydraulic prop 2, the interim top board of supporting carries out temporary lining, behind the permanent support to be performed, only need hydraulic prop 2 releases, hydraulic prop 2 drives back timber 1 and descends, and breaks away from top board, just can be used for temporary lining next time.
Therefore, the utlity model has simple in structurely, easy to use, gib school assignment quick safety also can be used for The end face out-of-flatness of geological conditions difference because forming, and save the characteristics such as manpower.
