Abstract
Disclosed is a self-guide omnibearing traveling type forepoling hydraulic support. A spiral drum serves as a forepoling hydraulic support traveling portion. By controlling the rotation direction and the rotation speed of a screw pair, the forepoling hydraulic support can autonomously conduct the motions of advancing, retreating, rotation, lateral movement and the like and has an omnibearing traveling function, especially, lateral linear displacement realizes direct displacement of the forepoling support under the close arrangement condition, and traveling of the forepoling support is achieved. In particular use, the last forepoling support in a roadway is moved to the middle of the roadway laterally, then moved forwards to the front of all the forepoling supports, and moved to the side of the roadway laterally, thereby becoming the first forepoling support instead of the last forepoling support. As the last forepoling support is directly moved to the foremost position from the backmost position, a roadway roof is not supported repeatedly in the moving process, and the problem that at present, the roof is damaged due to repeated supporting of forepoling supports is solved.
Description
Technical field
The present invention relates to a kind of autonomous guiding omnibearing ambulation advanced hydraulic support, is propped up in advance for coal mine work area tunnel
Shield.
Background technology
Advanced hydraulic support is used for underground coal mine roadway workface advance support.Advanced hydraulic support is mainly adopted and is pushed away at present
Move jack to move.Its move mode is, with former and later two hydraulic supports fulcrum each other, to be shunk jack, drawn using circulation
The mode for stretching jack is moved, and general length mobile every time is in 600～800mm or so.《Safety regulations in coal mine》Regulation,
Roadway workface advance support length is not less than 20m, due to advanced hydraulic support moving process in, need to shrink repeatedly column from
Open back-- elongation column contact back.Calculated with the distance that advance timbering is walked every time as 800mm, easily
Know which needs movement just cover whole process 25 times.In due to advance timbering moving process, repeatedly roadway surrounding rock top board is loaded, unloaded
Carry, cause back to loosen broken, difficulty is brought to the security maintenance in tunnel, how to solve advance timbering to back
Destruction is a great problem of current tunnel advanced hydraulic support supporting.The formula support of moving is to solve the problems, such as to support repeatedly destruction top board
One of effective means, invention 200910075084.4 discloses a kind of self-circulation type advanced hydraulic support, by the row such as crawler belt
Walking mechanism realizes stem to afterbody from shifting；Invention 201210260687.3 discloses a kind of circulation shift-forward type advance support system
By bracket carrier, system, can realize that he moves.Existing problems, the shift space under advanced close-packed arrays are less, self-moving type walking
Portion's solution does not have the function of lateral directly displacement, turns to difficult；He needs cargo handling process, complex operation at shifting formula.Advanced
One kind is needed in shield operation badly can be with all-around mobile, and the walking advance timbering of the poor roadway floor condition of condition of compatibility is realized
Circulation protective function.
The content of the invention
The invention aims to a kind of advanced hydraulic support of all-around mobile is provided, it is specifically a kind of to have independently
Advance, retrogressing, lateral translation, a kind of air way forepoling hydraulic support of spinfunction.
Technical scheme：The present invention arranges spiral rotary drum type running part on leading chock for drift, by pitch cylinder not
The actions such as advance, retrogressing, shifted laterally and the rotation of advance timbering are realized with rotation direction mode, the walking for solving advance timbering is asked
Topic.When specifically used, positioned at tunnel, a last advance timbering is moved laterally in the middle of tunnel, is advanced again into owning
The front of advance timbering, then tunnel side is moved laterally to, first is changed into from last original advance timbering and is propped up in advance
Frame, due to directly moving to forefront from rearmost position, the support repeatedly in moving process not to back is solved
Current advance timbering supports the destruction difficult problem caused to top board repeatedly.
Present invention tool has the advantage that.
(1) with helix drum as advanced hydraulic support running part, by the rotation direction and rotating speed that control spiral pair, advanced liquid
Pressure support can independently advance, retreat, rotating and the motion such as shifted laterally, possess omnibearing ambulation function, especially lateral straight line
Displacement realizes direct displacement of the advance timbering under the conditions of close-packed arrays.
(2) when advanced hydraulic support is moved, helix drum contact base plate, helix drum in the case where the action of lifting jack drives
Rotate and drive advanced hydraulic support movement；Advanced hydraulic support is moved when carrying, and helix drum is in the case where the action of lifting jack drives
Base plate is left, helix drum is not acted on by roof and floor power when advanced hydraulic support starts to carry.
(3) advanced hydraulic support solves existing tunnel advanced hydraulic support push unit by autonomous and moves repeatedly
The dynamic destruction caused by back.
Description of the drawings
Fig. 1 is the three-dimensional entity model figure of the present invention.
Fig. 2 is advanced hydraulic pressure in roadway support and middle circulation schematic diagram.In figure, 1- back timbers, 2- columns, 3- are stably propped up
Seat, 4- bases, 5- lifting jack, 6- fixed mounts, 7- helix drums, 8- power parts.
Specific embodiment
Below in conjunction with the accompanying drawings embodiments of the invention are further described.
As shown in figure 1, a kind of omnibearing ambulation advanced hydraulic support, is mainly used in advanced of tailentry road
Shield, including hydraulic support top beam（1）, column（2）, stable supporting（3）, base（4）, lifting jack（5）, fixed mount（6）, spiral shell
Rotating drum（7）, power part（8）Deng part.Helix drum（7）It is arranged in base（4）Both sides, when advanced hydraulic support needs movement
When, column（2）Shrink, back timber（1）Back is left, jack is lifted（5）Action, fixed mount（6）It is rotated down, spiral roll
Cylinder（7）Contact base plate.
A pair of right hand helix cylinders（7）, in power part（8）In the presence of synchronously turn clockwise, advance timbering is to the left
Move in parallel；Helix drum（7）Rotate counterclockwise simultaneously, advance timbering is moved in parallel to the right；The helix drum of both sides（7）One
Side rotates clockwise, and opposite side is rotated counterclockwise, and advance timbering advances or retreats；The helix drum of both sides（7）Asynchronous rotation
And rotating speed is inconsistent, advance timbering is then presented fillet motion.
Such as Fig. 2, tunnel both sides during advanced hydraulic support normal work, are arranged in（1. lower right support is in position）, tunnel
Walkway in centre, when leading chock for drift needs reach, column（2）Shrink, back timber（1）Back is left, is lifted
Jack（5）Action, fixed mount（6）It is rotated down, helix drum（7）Contact base plate, a pair of helix drums（7）Synchronous spiral shell in the same direction
2. rotation, advanced hydraulic support laterally shift to tunnel medium position；Then tunnel advanced hydraulic support is shifted to tunnel and is surpassed
3., then 4. tunnel advanced hydraulic support is moved laterally to tunnel lateral location, is changed into tunnel for fore-stock group forefront position
The first advanced hydraulic support of advanced hydraulic support group.By above-mentioned moving direction, by original advanced hydraulic support group
Last support of group is changed into coming the hydraulic support of foremost, solves current tunnel advanced hydraulic support push unit
Move repeatedly the destruction caused to back.
Above-described embodiment is that the effective embodiment to the present invention is described, and not the scope of present aspect is limited
It is fixed, under the premise of the design spirit without departing from the present invention, various modifications and change that ordinary skill technical staff is made to the present invention
Enter, all should fall in the protection domain of claims of the present invention determination.
