Abstract
The utility model relates to a moving structure of step-type mine roof support which is supported by a working surface and connected with a top beam, mainly characterizing in that the structure is composed of a single piston two-way cylinder and an elastic coupling slide block device formed by a guide arm and a slide block. The moving structure is easy to be processed with reliable running, flexible operation, and specially adapts to the movement of walking hydraulic support.
Description
The utility model relates to the advancing mechanism of the step-by-step movement mine roof support that links to each other with back timber of face timbering, is specially adapted to the passing of walking type hydraulic supports.
" hydraulic prop for moving suspended top beam " that CN88104291 proposed of prior art, thrust gear connects by two groups of flexible quadric chains, and the propelling oil cylinder of hinge knot on a back timber is hinged with the hinge that waves that is connected on another back timber.And every group of flexible quadric chain is made up of upper and lower flexible connecting rod, upper and lower spacing plate, slide block and the seat board that is fixed on the back timber, this thrust gear that is installed on the set cap, can realize that half uninstall moves frame, and can adapt to the variation of top board injustice, but it is little to pass step pitch, and support is still with the step reach.
And provide the thrust gear of a kind of " walking type hydraulic supports " in the CN9027165.3 patent documentation, be that passing oil cylinder and link block device are installed on the back timber, what wherein pass the oil cylinder employing is the double-piston two-way cylinder, one end piston rod of its double-piston two-way cylinder and back timber rear portion hinge knot, the other end piston rod of double-piston two-way cylinder is connected with the front portion of another back timber.Relative inner at left and right sides back timber all has slideway, and being equipped with on slideway can be along the two groups of connections in the front and back slide block device of slideway slippage, and every group connects slide block by master, pair slide block composition, be to tie by upper and lower two connecting rods hinge between master, pair slide block.Though this support thrust gear can be realized the reach of taking a step of big step pitch, need the two-way passing jack of double-piston, and the slideway of slide block processes on left and right back timber, and inconvenience is also arranged during use.
The purpose of this utility model is to overcome the deficiency in the prior art, proposes a kind of thrust gear of hydraulic support, can replace slideway with guide rod, and can use single piston two-way jack, thereby reaches reliable, flexible operation, effect easy to use.
Major technique measure of the present utility model is: two groups of resilient connection slide block devices are installed on the left and right back timber of each support, every group of resilient connection slide block device is by four guide rods, link to each other with four guide rods respectively and be fixed on ear seat on the back timber of the left and right sides, be through on the lower guide rod and also can form along two slide blocks about last lower guide rod slippage, about two slide blocks link up by hinge knot two groups of elastic links up and down thereon, and every group of elastic link is by a pair of rod member with pressure mounting of the spring together; Simultaneously, the left and right sides back timber of each support respectively has a single piston two-way to pass oil cylinder, and each cylinder body of passing oil cylinder is connected on the slide block of front and back, and its piston rod hinge knot of passing oil cylinder is on the back timber of the same side.
The technical measures that the utility model is taked also include: the guide rod in the elastic coupling slide block mechanism is cylindrical rod member, guide rod is divided into two sections of front and back, every segment length is 500～700 millimeters, guide rod all is fixed on the back timber by ear seat 2,3, one in the elastic link is the knee spare of band quarter bend, another is a straight-bar spare, and this a pair of rod member is fitted in together with spring and nut, can adorn the stop collar of a restraining spring decrement therebetween; Certainly, also can be the knee spare of a band quarter bend and the straight-bar spare of a tape spool shoulder, this a pair of rod member is fitted in together with spring and nut, and this shaft shoulder plays position-limiting action by the restraining spring decrement; Single piston two-way on the back timber of the left and right sides is passed cylinder body and is passed the circular hole above the slide block and connect thereon with steel wire.
Compared with the prior art the hydraulic support thrust gear that is provided in the utility model has following advantage:
1, the elastic coupling slide block can be along the guide rod slippage, under the effect of passing oil cylinder, the passing of back timber is carried out along guide rod, replaced slideway with guide rod like this, because the quality of fit between guide rod and the link block realizes that easily guide rod rigidity also guarantees easily, and may be easier to avoid bring the not smooth fault of slippage because of the back timber distortion, thereby reliable, flexible operation, easy to use.
2, can not only simplify the structure, and back timber is shortened with the replacement double-piston two-way cylinder of single piston two-way oil cylinder, the distance of face roof under control of back timber is reduced.
Description of drawings of the present utility model is as follows:
Fig. 1 hydraulic support thrust gear structure chart
Fig. 2 hydraulic support thrust gear sectional view
Below in conjunction with accompanying drawing embodiment of the present utility model is described as follows: two groups of resilient connection slide block devices before and after being equipped with between the back timber of the left and right sides, wherein guide rod 1 is cylindrical rod member, every guide rod 1 length is 600 millimeter, be distributed as 8 up and down by front and back, be fixed in left and right sides back timber one side with ear seat 2,3 respectively, the front and back guide rod is answered arranged in co-axial alignment certainly.On guide rod 1, be installed with slide block 4, every two guide rods 1 up and down pass same slide block 4, about link with elastic link 5 between two slide blocks, every group of slide block all is by two groups of elastic links 5 of bearing pin hinge knot, every group of elastic link 5 is again to be press-fited by spring 9 and nut 10 by a pair of rod member, in this a pair of rod member one be the band quarter bend 7, one of knee spares be straight-bar spare 8, straight-bar spare 8 can install a stop collar that is slidingly matched 11 additional, so that restraining spring 9 is in decrement.
Left and right sides back timber opposite side is respectively installed a single piston two-way oil cylinder 6, its piston rod hinge knot is on the bearing 12 that is fixed in left and right sides back timber, and its cylinder body passes the circular hole of front and back slide block 4, link thereon with steel wire, certainly slide block 4 also can adopt other connected modes before and after cylinder body connected, be that the through hole that cylinder body passes a slide block 4 links with steel wire, and the end face of cylinder body connect on another slide block 4 of homonymy by ball pivot.Between single piston two-way oil cylinder 6 of left and right sides back timber opposite side, use flexible pipe 13 conductings.
