Technical field
The present invention relates to a kind of coal mine machinery, more particularly to a kind of mining hydraulic support meanss.
Background technology
China is one of very plentiful and substantial country of coal resource, and the content and yield of coal often occupy world prostatitis, coal
Have become the indispensable resource of China's dependence.Coal resources in China distributional region is very broad, and coal seam memory state is also each
Kind of various kinds, typically have it is following some：
1st, with country rock and colliery storage relation analyses, the Chinese existing colliery being stored under soft rock roadway and common top board
Under the conditions of colliery, the seam mining difficulty being also present under the colliery resisted stubbornly under plate, tight roof is quite big, and Jing often has greatly
About 1000 square metres of outstanding ejection shows, just in case being just likely to cause very serious disaster if collapsing, suffers heavy losses.
2nd, analyzed with the geological environment of colliery storage, because topographic features and its complexity, colliery is led due to crustal movement
The fault-layer-phenomenon of cause is very universal；Typically in the middle of common coalfield, the gap in so several whole coalfields of shuttling always is had
Than larger tomography, less big tomography is even more of common occurrence.
3rd, to analyze on the storage condition in colliery itself, flat seam, inclined seam, half-edge coal seam, reversing
Coal seam can be found in China's coal-mine rock stratum.The many colliery rock stratum of existing more Relative steady-state, also have as bird's nest shape
Coal seam, substantially has anyway miscellaneous.
Recent years, caused accident was too many because colliery caves in, original to adopt what waddy was supported in the support to colliery
Mode, is supported in the way of waddy and is existed, and lumber consumption is larger, is unfavorable for environmental conservation, and because the length of waddy can not
Adjust, it is very inconvenient when in use.Later colliery, but this were supported using fricting supporting pillar or automatic transfer type hydraulic prop
Post usually individually adjusts its lifting, and when controlling multiple pillars by control device and lifting, it is larger to there is volume, peace
Dress inconvenience, the shortcomings of.

Hydraulic prop 2 includes liquid oil cylinder 18, is connected to support the carrier bar 19 in colliery on the piston rod of the oil cylinder 18, described
The epimere of carrier bar 19 is provided with gripper shoe 20, in the upside of the carrier bar 19 or through hole, gag lever post 21 in through hole, in institute
State and handle 22 is additionally provided with oil cylinder 18.
A second reversal valve 5b is equipped with each described branch pipe(tube) 4, the second reversal valve 5b is also adopted by three
Four-way battery valve, each described branch pipe(tube) 4 connects pressure switch 6 and energy storage canister 7, the pressure switch 6 by pipeline
And energy storage canister 7 is arranged between corresponding second reversal valve 5b and hydraulic prop 2.
The power supply device 1 includes the first fuel tank 8, and first fuel tank 8 is commutated by the connection of the first energy supply pipeline 9 first
Valve 5a, is provided with the first hydraulic pump 10 on the first energy supply pipeline 9, and first fuel tank 8 is connected by the second energy supply pipeline 28
The 3rd energy supply pipeline 11 is connect, the second hydraulic pump 13 is provided with the second energy supply pipeline 28, in the 3rd energy supply pipeline 11
On be respectively equipped with relief valve 14 and auxiliary device 15, the second energy supply pipeline 28 be connected to relief valve 14 and auxiliary device 15 it
Between, the auxiliary device 15 includes being connected to the pressure switch 6 of the end of the 3rd energy supply pipeline 11, in the side of pressure switch 6

During the cavity of resorption of hydraulic prop 2, piston rod 25 raising will come therewith, hereafter when piston rod 25 is no longer raised, close fluid injection
Rifle 23, while check valve 24 is closed, piston rod rises and completes.
B, carrying overflow
When the working resistance that relief valve 26 is limited is less than roof pressure, relief valve 26 is opened, and the relief valve 26 is adopted
With direct-acting overflow valve, at this moment liquid will outwards be diffused out and, and now the chamber pressure of hydraulic prop 2 will reduce therewith, hydraulic pressure
The piston rod 25 of pillar 2 is just shrinkable.When the working resistance that hydraulic prop 2 is subject to is more than supported gravity, peace
Full valve 26 will be automatically switched off therewith, very easy to use.The liquid of the inner chamber of hydraulic prop 2 will terminate outwards spilling
's.This process can constantly repeat in pillar supporting whole process.Then, the yield load of hydraulic prop 2
Typically load of pillar or so can be all maintained at, so be more beneficial for carrying overflow.
C, unloading drop post
Feather valve 27 is opened, the feather valve 27 adopts manual type sequence valve, the inner chamber of such hydraulic prop 27
Liquid is discharged.Hydraulic prop 27 shrinks under the dual function of gravity work and back-moving spring, and so as to complete whole unloading post is dropped
Process.
