Description
Technical field
Suspension roof support support of the present invention, belongs to coal mining machine mechanical equipment technical field.
Background technology
Development machine is a kind of high-efficiency appliance in mine excavation tunnel, and complete machine specifically includes that cutting units, transhipment portion, first conveyor, body, running part, rear support portion etc..During work, in order to keep the safety in production, need in time the top board newly come out to be carried out gib and anchor pole operation after development machine cutting coal body, the most conventional method for protecting support is: after development machine carries out excavation operation, slow astern set a distance is the most out of service, perforating is propped up nurse and is carried out supporting to work surface beat anchor pole from development machine rear carrying roof-bolter and support material, this kind of method labor intensity is big, longevity of service, production efficiency is low, and the time that these two parts need typically constitutes from more than the 50% of the roadway opening time.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, technical problem to be solved to be to provide a kind of step-by-step movement suspension roof support support, is used conveniently and safely.
nullIn order to solve above-mentioned technical problem，The technical solution adopted in the present invention is: suspension roof support support，Including front-axle beam、The back rest、Trave lling girder、Column、Anchor Care beam、Two pass rail and passage oil cylinder，Anchor Care beam two ends are fixedly set in the front end of two pass rail respectively，The two ends of the back rest are fixedly set in the rear end of two pass rail respectively，The middle part of two pass rail is also movably installed with trave lling girder and front-axle beam，Front-axle beam is installed near Anchor Care beam，Trave lling girder is installed near the back rest，Described trave lling girder and Anchor Care beam are rectangular frame，It is provided with the jacking of multiple extension Air Filter by support oil cylinder on Anchor Care beam，Before described、The back rest、Two ends and trave lling girder four ends below be fixedly connected with a column and all of column is hydraulic cylinder type，The cylinder body of passage oil cylinder it is installed with on the back rest，The piston rod of described passage oil cylinder is horizontally disposed with and end is fixing with trave lling girder is connected.
The bottom of described column is provided with end boots.
It is installed with two passage oil cylinders be arrangeding in parallel on the described back rest and two piston rod ends elapsing oil cylinders are all fixed with trave lling girder and are connected.
The had the beneficial effect that present invention of the present invention passes through the expanding-contracting action of a passage oil cylinder, the back rest and trave lling girder is made to realize step-by-step movement walking with the alternating movement of one movement of a fixed point, achieve the transfer in tunnel of the Anchor Care beam, it is not required to manpower carry out carrying perforator installation before development machine, is used conveniently and safely.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the plan structure schematic diagram of the present invention.
Fig. 3 is the forward and backward beam transfer schematic diagram during the present invention advances.
Fig. 4 is the trave lling girder transfer schematic diagram during the present invention advances.
In figure: 1 is front-axle beam, 2 is the back rest, and 3 is trave lling girder, and 4 is column, and 5 is Anchor Care beam, and 6 is two pass rail, and 7 is passage oil cylinder, and 8 is jacking.
Detailed description of the invention
nullSuch as Fig. 1、Shown in Fig. 2，Suspension roof support support of the present invention，Including front-axle beam 1、The back rest 2、Trave lling girder 3、Column 4、Anchor Care beam 5、Two pass rail 6 and passage oil cylinder 7，Anchor Care beam 5 two ends are fixedly set in the front end of two pass rail 6 respectively，The two ends of the back rest 2 are fixedly set in the rear end of two pass rail 6 respectively，The middle part of two pass rail 6 is also movably installed with trave lling girder 3 and front-axle beam 1，Front-axle beam 1 is installed near Anchor Care beam 5，Trave lling girder 3 is installed near the back rest 2，Described trave lling girder 3 and Anchor Care beam 5 are rectangular frame，It is provided with the jacking 8 of multiple extension Air Filter by support oil cylinder on Anchor Care beam 5，Before described、The back rest 1、It is fixedly connected with a column 4 below two ends of 2 and four ends of trave lling girder 3 and all of column 4 has been hydraulic cylinder type，The cylinder body of passage oil cylinder 7 it is installed with on the back rest 2，The piston rod of described passage oil cylinder 7 is horizontally disposed with and end is fixing with trave lling girder 3 is connected.
The bottom of described column 4 is provided with end boots 9.
It is installed with two passage oil cylinders 7 be arrangeding in parallel on the described back rest 2 and two piston rod ends elapsing oil cylinders 7 are all fixed with trave lling girder 3 and are connected.
Work process
Original state of the present invention is as it is shown on figure 3, when it is advanced in tunnel, first the column 4 under trave lling girder 3 is contraction state, and boots of the corresponding end 9 leave ground, and the column 4 of forward and backward beam 1,2 is the state of stretching out, location, its underpart and top support；
The piston rod controlling passage oil cylinder 7 stretches out, and shortens the distance between front-axle beam 1 and trave lling girder 3；
Then, as it is shown in figure 1, the column 4 under trave lling girder 3 stretches out, top support and lower bottom boots are made to land fixed point；
Then, as shown in Figure 4, the column 4 under forward and backward beam 1,2 is retracted, and boots of the corresponding end 9 leave ground, and the piston rod controlling passage oil cylinder 7 is retracted, and shortens the distance between the back rest 2 and trave lling girder 3, makes entirety of the present invention take a step forward；
Finally, the column 4 under forward and backward beam 1,2 stretches out so that it is location, bottom and top support, trave lling girder 3 lower pillar stand 4 is retracted, and returns to original state as shown in Figure 3；
So far stepping transfer is completed, continue that aforesaid operations process is repeated several times and can easily the present invention be moved to mount point.
