Abstract
The utility model discloses a support frame base for thin-seam coal faces, comprising a horizontal bottom plate; more than one stand column and hinge seat are arranged on the upper surface of the bottom plate; the bottom plate is of a strip-shaped structure; and four edges at the bottom surface of the bottom plate are chamfered arcs. According to the utility model, a plurality of single hydraulic props can be arranged on the bottom plate and can be connected with a bidirectional jack, so that after coal cutting on a coal cutting plane is finished, the bidirectional jack can be used for driving the base provided by the utility model to move forwards and driving the single hydraulic props to move toward the coal cutting plane. The single hydraulic props are connected by using the base, so that after the mining on a working plane is finished, the dismounting and mounting are free of manpower and the acting force of the bidirectional jack is utilized to carry out direct forward propulsion.
Description
Technical field
The utility model relates to a kind of coal-face suspension device.
Background technology
China verified the girdle reserves have 60 surplus hundred million tons (coal seam thickness is less than 1.3m), compare with high seam, girdle mechanical mining difficulty is big, yields poorly, cost is high, ample resources goes out of use or shelves because of technical condition.
On the mining operations face in coal seam, need pillar the end face of production face is carried out supporting, collapse to prevent end face.
The supporting of girdle coal-face develops into hydraulic prop by wooden prop, and the hydraulic prop setting load is big, and support capacity is strong, and is simple to operate, uses hydraulic prop that face roof control is improved greatly, has obtained more general application.But the single weight of hydraulic prop is bigger, though short more pillar weight is light more, the short more work plane mining height of pillar is also short more, and the operator still need bear out sizable muscle power when pillar, prop drawing, and the time of pillar and prop drawing is also longer.Will further improve single face output, reduce the manual labor of pillar, prop drawing, shortening pillar, prop drawing time have become the key of further raising single face output.At present, a lot of hydraulic support manufacturers can both produce and be applicable to the hydraulic support of coal-face as thin as a wafer, the minimum 0.7m that reaches.The part coal seam geological condition is work plane preferably, has gradually adopted hydraulic support.But the hydraulic support price is very expensive, condition of coal seam occurrence is required comparatively harsh; The big transportation of support volume is difficulty very, and in order to satisfy the transportation of support, span length has to widen; Thereby the increase cost of winning, single frame weight support frame is big, transfers the frame difficulty; Hard transportation, it is long to cause work plane to move the time, bigger to producing influence.
The utility model content
In order to overcome the above defective, the utility model provides a kind of supporting frame base that is used for the girdle coal-face.The use that has promptly kept hydraulic prop flexibly, the convenient transportation advantage, have the convenience of hydraulic support pillar, prop drawing and manual labor to consume few characteristics again.
The utility model comprises the base plate 2 of horizontal positioned, and more than one column 1, hinge seat 3 are set on base plate; Base plate 2 is a strip structure, and the bottom surface four edges is circular arc chamfering.
According to above-mentioned main points, illustrating further to, the utility model base plate 2 is wide is 300～400mm, and column 1 diameter is 50～70mm, and height is 310～340mm, and is evenly distributed on the base plate.
According to above-mentioned main points, illustrate further into, the utility model column 1, hinge seat 3 all are arranged at plate upper surface.
Through the column on the utility model base plate, can a plurality of (generally at least three) hydraulic prop 7 be arranged on the base plate 2, and the even hinge block 3 through being provided with on it, connect a two-way jack 5, form the disjunctor support.Like this, after accomplishing the coal cutting of face coal, can move forward, drive a plurality of (generally at least three) hydraulic prop 1 simultaneously and move to coal cutting face by the base that two-way jack 5 drives the utility model.
Use the utility model to connect a plurality of hydraulic props 7, can after the exploitation of accomplishing a work plane, need not utilize manual work to go dismounting, install, just can utilize the active force of two-way jack 5, directly integral body be pushed ahead.So not only saved a large amount of manpowers, more saved great amount of time, improved working efficiency and output of coal, the utility model processing maintenance easily; Little, the in light weight convenient transportation of volume.
Description of drawings
Fig. 1 is the structure chart of the utility model;
Fig. 2 is the vertical view of the utility model Fig. 1;
Fig. 3 is that utility model is used sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
When using the utility model, the hole of hydraulic prop 7 bottoms is cooperated with column 1 on the base plate and hydraulic prop 7 is fixed on the base, can fix three at least; Two-way jack 5 is fixed through hinge seat on the base plate 23 and base, the front end of two-way jack 5 can with climb coal scraper-trough conveyer 4 and be connected.
When coal work, concrete operation method is following:
After the coal cutting, the thrust that makes two-way jack 5 will be climbed coal scraper-trough conveyer 4 and advance to the rib direction forward, accomplish and move the preface of sneaking away during work hours.Hydraulic prop positive supporting 7 this moments on the base is at the coal-face end face.
During prop drawing,, and start two-way jack 5 once more with the whole releases of monomer hydraulic pressure 7 pillars; Make two-way jack 5 produce pulling force; Base is spurred to the rib direction together with the hydraulic prop on it 7, after pulling puts in place, rise hydraulic prop 7 again; Reach the effect of supported face, accomplish prop drawing, pillar operation.Because hydraulic prop 7 is arranged on the base, so when two-way jack 5 spurs, with three (can be three at least) hydraulic props 7 pulling forward simultaneously, accomplish prop drawing, pillar operation simultaneously time saving and energy savingly.
Combined accompanying drawing that the specific embodiment of the utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that in the utility model scope, carry out all do not exceed the protection domain of the utility model.
