Abstract
The invention discloses the slippage bracket of taking a step that a kind of step pitch is increased, solve the problems, such as that existing apparatus step pitch is small, labour intensity is big, it is characterized in that setting guide post, balladeur train fixed seat on described auxiliary girder, balladeur train, big balladeur train are set on girder, the other end of balladeur train sets on the guide bar；Big balladeur train includes two semi-ring fairleads with jack cooperation of taking a step, big balladeur train by two semi-ring fairleads be fixed on jack of taking a step it is cylindrical on；Take a step jack front end connection balladeur train, rear end connection balladeur train fixed seat；Balladeur train is slided on the guide bar.The present invention is only with a guide post, it is aided with the cylindrical guiding of jack of taking a step again, in the case where back timber length is not increased, the step pitch of slippage bracket is increased, without improving timberer's resistance, structural strength, back timber length and sectional area, column cylinder diameter etc., support input is reduced, equipment is light and handy, more convenient operation, is that thin seam working surface saves height space, greatly improves production efficiency etc..
Description
Technical field
The present invention relates to a kind of support apparatus in coal mine, taken a step slippage bracket more particularly to one kind.
Background technology
Slippage bracket of taking a step is the common equipment of underground coal mine supporting, conventional design is before being provided between girder, auxiliary girder,
Latter two guide post, a jack of taking a step, the front and back end of jack of taking a step respectively on two guide posts, in two guide posts
Upper movement.Due to the restriction in this structure, each step pitch taken a step has certain limitation：Firstly, since supporting power and
The limitation of stability etc., major and minor beam can not possibly be long, and former and later two guide posts add one, the middle part length of jack of taking a step just
There is larger limitation, so limit the i.e. step pitch of distance of taking a step of slippage bracket, it is deep to limit cutting for coal-winning machine, particularly pushes up bottom
In the case of slat element is preferable, production efficiency does not increase.Secondly, scrapper conveyor passage and the operation of taking a step of slippage bracket, become phase
To relatively frequently, and operating will expend substantial amounts of labour each time, increase labour intensity, burden of keeping the safety in production is raw
Produce efficiency is influenceed by certain.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art to provide the slippage bracket of taking a step that a kind of step pitch is increased, not
In the case that increase major-minor beam length does not increase support control top load, the step pitch of slippage bracket is increased.
The present invention includes girder, auxiliary girder, guide post, jack of taking a step, it is characterised in that：Set on described auxiliary girder and be oriented to
Bar, balladeur train fixed seat, set balladeur train, big balladeur train on girder, and the other end of balladeur train sets on the guide bar；Big balladeur train includes and steps
Step jack coordinate two semi-ring fairleads, big balladeur train by two semi-ring fairleads be fixed on jack of taking a step it is cylindrical on；
Take a step jack front end connection balladeur train, rear end connection balladeur train fixed seat；Balladeur train is slided on the guide bar.
Two guide posts of traditional design are added a jack of taking a step by the present invention, are changed to only with a guide post, then auxiliary
With the cylindrical guiding of jack of taking a step, the length of so major and minor beam is only by a guide post and a jack distribution, Ke Yi
In the case of not increasing major and minor beam length, the length of take a step jack and guide post can be significantly increased, so that slippage bracket
Step pitch is also significantly increased.
Above-mentioned technical proposal understands that the present invention is not increasing back timber by Transform Type design（That is major-minor beam）Length is control top
In the case of, the step pitch of slippage bracket is increased, such as, the working face that original cuts deep 600mm rises to a section deep 1000mm, without
Timberer resistance, structural strength, back timber length and sectional area, column cylinder diameter etc. are improved, support input is reduced, equipment is lightly, more square
Convenient to operate, is that thin seam working surface saves height space, greatly improves production efficiency etc..

Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention includes girder 1, auxiliary girder 2, guide post 3, balladeur train 4, jack 5 of taking a step, balladeur train fixed seat 7
Deng.Guide post 3, balladeur train fixed seat 7 are set on auxiliary girder 2, balladeur train 4, big balladeur train 6, the other end of balladeur train 4 are set on girder 1
It is located on guide post 3, big balladeur train 6 includes two semi-ring fairleads 61 with the cooperation of jack 5 of taking a step, big balladeur train 6 passes through two halves
Ring fairlead 61 be screwed in jack 5 of taking a step it is cylindrical on；Take a step the front end of jack 5 connection balladeur train 4, rear end connection slide
Frame fixed seat 7, balladeur train 4 is slided on guide post 3.
Fig. 2 show coal-winning machine 8, scrapper conveyor 9 schematic diagram supporting with the present invention.When slippage bracket of taking a step needs movement
When, auxiliary girder 2 is under holding state（Adjacent frame is also at holding state）, girder front column 10, girder rear column below girder 1
After 12 unloadings, to the feed flow of jack 5 of taking a step, using the bearing on auxiliary girder 2 as the strong point, piston rod is pushed away the outer shell of jack 5 of taking a step
Dynamic girder 1 moves ahead to rib, at this moment balladeur train 4 and big balladeur train 6 respectively along guide post 3 and jack 5 of taking a step cylinder barrel it is cylindrical to
Rib direction is slided, and is oriented to girder 1.After girder 1 in place after, prop girder front column 10, girder rear column 12 below,
Girder 1 is set to be in holding state.Then it is that auxiliary girder front column 11, auxiliary girder rear column 13 are unloaded by the front and rear column below auxiliary girder 2,
To the reverse feed flow of jack 5 of taking a step, with the bearing on girder 1 as the strong point, auxiliary girder 2 is pulled to move forward, at this moment balladeur train 4 and big balladeur train
6 are oppositely oriented bar 3 and the cylinder barrel of jack 5 of taking a step respectively does counter motion, is oriented to auxiliary girder 2.Pair is propped after auxiliary girder 2 is in place
The auxiliary girder front column 11 of beam 2, auxiliary girder rear column 13, you can complete once taking a step for support.
