The invention provides a fully mechanized coal-mining and fully mechanized caving face hydraulic support. The support comprises a plurality of shed beams, a supporting roof and shed feet. The shed beams are arranged in the same horizontal plane in parallel, the supporting roof is laid on the shed beams, each shed beam is supported by one unique shed foot, one end of each shed foot is inserted into the corresponding shed beam, and the other end of each shed foot abuts against the ground. By the adoption of the fully mechanized coal-mining and fully mechanized caving face hydraulic support, waste of materials is effectively reduced, manpower and working time are saved, and meanwhile safety production can be guaranteed.
Description
Technical field
The present invention relates to a kind of combining and adopt hydraulic support of top-coal saving face.
Background technology
The comprehensive fully mechanized coal face of adopting need to be left and taken ventilation air duct conventionally when work, to provide enough amounts windward to work plane.
Combine and to adopt the common employing retrusive of withdrawing of hydraulic support of top-coal saving face and withdraw method, after from bottom to top hydraulic support being extracted out, top board is caving thereupon.In order to ensure work plane, meet head on to ventilate unimpeded, when hydraulic support is extracted out, need to stay and establish ventilation air duct.
Existing hydraulic support construction system is as shown in Fig. 1 a and 1b.Fig. 1 a illustrates the existing top view of adopting hydraulic support of top-coal saving face of combining, and Fig. 1 b is the sectional view along the A-A face intercepting in Fig. 1 a.As Fig. 1 a and 1b visible, in existing hydraulic support, each capplce is supported by two canopy pin.And in hydraulic support, need to adopt capplce-canopy leg structure that quantity is larger.Therefore, adopt this construction system to withdraw complete work plane, timber consumption is very big, and need to expend a large amount of manpowers and working time.Meanwhile, owing to adopting the erection mode of two canopy pin, staff also easily touches hand and touches the even personal injury of slight wound of pin, has also increased thus work danger.
Summary of the invention
The invention provides a kind of combining and adopt hydraulic support of top-coal saving face, effectively reduced waste of material, saved manpower and working time, can also ensure safety in production simultaneously.
Particularly, the invention provides a kind of combining and adopt hydraulic support of top-coal saving face, this support comprises capplce, supporting roof, canopy pin, many described capplce is set in parallel in same level, supporting roof is laid on many described capplces, and wherein, every capplce is supported by a unique canopy pin, peg graft in capplce in canopy pin one end, the other end pushes up on the ground.
Preferably, canopy pin tilts with respect to vertical curve.
More preferably, the angle that canopy pin tilts with respect to vertical curve is between 3 °-5 °.
Preferably, according to the lithology situation on supporting roof, calculate the supporting intensity of supporting roof, to determine the spacing between every adjacent two capplces.
Preferably, the spacing between every adjacent two capplces is between 700mm-800mm.
More preferably, described spacing equals 750mm.
Preferably, described capplce is by the wooden one-tenth that strips off the skin.
Preferably, described capplce is being that 2 meters long and cross-sectional diameter are cylindrical between 150mm-180mm in shape.
Preferably, canopy leg is by oval wooden one-tenth.
More preferably, the length of described canopy leg is 2.5 meters-3 meters.
More preferably, the length of described canopy leg equals 2.8 meters.
Provided by the present invention combine adopted hydraulic support of top-coal saving face the supporting of original pair of canopy pin changed into the supporting of single canopy pin, still can guarantee the unimpeded of air channel, and significantly change does not occur the air quantity in air channel.Meanwhile, adopt single canopy pin supporting and protection structure, can save lot of materials consumption, in practical operation, even can be less surpass the material consumption of half, saved manpower and working time simultaneously.Further, the in the situation that of single canopy pin supporting, than two canopy pin supporting and protection structure, staff is also comparatively not easy to touch hand and touches the even personal injury of slight wound of pin, makes thus safety be greatly improved.
Accompanying drawing explanation
Fig. 1 a illustrates the existing top view of adopting hydraulic support of top-coal saving face of combining;
Fig. 1 b is the sectional view along the A-A face intercepting in Fig. 1 a;
Fig. 2 a illustrates according to the top view of adopting hydraulic support of top-coal saving face of combining of the present invention;
Fig. 2 b illustrates structure shown in Fig. 2 a along the sectional view of section B-B intercepting.
The specific embodiment
Hereinafter, identical Reference numeral refers to identical element.
Generally, provided by the present invention combine adopted hydraulic support of top-coal saving face and changed existing support pattern, change the supporting of original pair of canopy pin the supporting of into single canopy pin, guaranteeing under the prerequisite of supporting intensity, still can guarantee the unimpeded of air channel, than two canopy pin supporting and protection structure, can there is not remarkable change in single canopy pin supporting and protection structure in ventilation.
Fig. 2 a illustrates according to the top view of adopting hydraulic support of top-coal saving face of combining of the present invention, and Fig. 2 b illustrates structure shown in Fig. 2 a along the sectional view of section B-B intercepting.
As visible in Fig. 2 a, supporting roof is laid on a plurality of capplces 1 in same level.Preferably, a plurality of capplces 1 be arranged in parallel in each other, to more stably support supporting roof.
Each capplce 1 is supported by a unique canopy pin 2.Particularly, peg graft in capplce 1 in canopy pin 2 one end, and other end top on the ground, thereby support its capplce 1.
As visible in Fig. 2 b, canopy pin 2 can tilt with respect to vertical curve.Preferably, the angle that canopy pin 2 tilts with respect to vertical curve is between 3 °-5 °.
In order adapting to better to combine to adopt, to combine the working environment of putting, can to consider that the spacing between every adjacent two capplces 1 is between 700mm-800mm, more preferably, spacing can be set as 750mm.Capplce 1 can be by the wooden one-tenth that strips off the skin.Especially, capplce 1 can be that 2 meters long and cross-sectional diameter are cylindrical between 150mm-180mm in shape.Particularly, can calculate the supporting intensity of supporting roof according to the lithology situation on supporting roof, to determine the spacing between every adjacent two capplces.
Canopy leg 2 can be by oval wooden one-tenth, and length can be arranged to 2.5 meters-3 meters, and especially, length can be 2.8 meters.
In application, according to of the present invention, combine while adopting hydraulic support of top-coal saving face, can be by grasping the lithology situation of different coal top board, calculate the supporting intensity that supporting roof needs, can guarantee under the prerequisite of supporting intensity thus, guarantee to combine the unimpeded of air channel when adopting fully mechanized coal face and withdrawing, and guarantee enough air quantity.
To sum up, provided by the present invention combine adopted hydraulic support of top-coal saving face the supporting of original pair of canopy pin changed into the supporting of single canopy pin, still can guarantee the unimpeded of air channel, and significantly change does not occur the air quantity in air channel.Meanwhile, adopt single canopy pin supporting and protection structure, can save lot of materials consumption, in practical operation, even can be less surpass the material consumption of half, saved manpower and working time simultaneously.Further, the in the situation that of single canopy pin supporting, than two canopy pin supporting and protection structure, staff is also comparatively not easy to touch hand and touches the even personal injury of slight wound of pin, makes thus safety be greatly improved.
Those skilled in the art will also be appreciated that protection scope of the present invention is not limited in above-described embodiment, all equivalents of the present invention are all fallen within the scope of the invention.
