Description
Technical field
The present invention relates to a kind of omnibearing walking advanced hydraulic supports to be used for coal mine work area lame advanced supporting.
Background technology
Advanced hydraulic support is used for underground coal mine roadway workface advance support.Advanced hydraulic support is mainly used and is pushed away at present
Jack is moved to be moved.Its move mode is shunk using cycle very heavy with former and later two advanced hydraulic supports fulcrum each other
Top, the mode for stretching jack are moved, and the distance generally moved every time is in 600~800mm or so.《Safety regulations in coal mine》
Regulation, roadway workface advance support length are not less than 20mm, are shunk repeatedly due in advanced hydraulic support moving process, needing
Column leaves back-- elongation column contact back, and the distance walked every time with advanced hydraulic support is 800mm
It is calculated, is apparent from it and needs just cover whole process mobile 25 times.Due in advanced hydraulic support moving process, repeatedly to tunnel
Top plate load, unloading cause back to loosen broken, bring difficulty to the security maintenance in tunnel, how to solve advanced hydraulic pressure
Holder is to a great problem that the destruction of back is current advanced hydraulic support supporting.The formula holder of moving is to solve advanced hydraulic pressure
Holder supports one of the effective means for destroying top plate problem repeatedly, and it is super that invention 200910075084.4 discloses a kind of self-circulation type
Preceding hydraulic support realizes stem moving certainly to tail portion by walking mechanisms such as crawler belts；Invention 201210260687.3 discloses one
Kind cycle shift-forward type advance support system, can realize that his moves by bracket carrier.There are problem, advanced hydraulic support is closely arranged
Shift space under row is smaller, and the solution not lateral function of directly shifting in self-moving type walking portion turns to difficult；He moves formula
Cargo handling process is needed, it is complicated for operation.Advance support operation there is an urgent need for one kind can with all-around mobile, adapt to poor roadway floor condition
Walking advanced hydraulic support, realize cycle protective function.
Invention content
The purpose of the invention is to provide a kind of advanced hydraulic support of all-around mobile, it is specifically a kind of have before
Into, retrogressing, the advanced hydraulic support of lateral translation, rotation function.
Technical solution：Spiral rotary drum type running part is arranged in the present invention on advanced hydraulic support, not by screw pitch roller
Advance, retrogressing, lateral movement and the spinning movement that advanced hydraulic support is realized with rotation direction mode, solve the row of advanced hydraulic support
Walk problem.When specifically used, an advanced hydraulic support last positioned at tunnel is moved laterally among tunnel, is moved further along
The forefront of advanced hydraulic support group is moved, then is moved laterally to tunnel side, by last original advanced hydraulic pressure branch
Frame becomes coming the first advanced hydraulic support of advanced hydraulic support group foremost, due to directly being moved from rearmost position
To forefront, not to the support repeatedly of back in moving process, solves current advanced hydraulic support and support repeatedly pair
The problem that top plate damages.
Present invention tool has the advantage that.
(1) use helix drum as advanced hydraulic support running part, by controlling the rotation direction and rotating speed of helix drum, in advance
Hydraulic support can independently advance, retreats, rotates and be displaced sideways, and have omnibearing ambulation function, especially lateral line shifting
Realize direct displacement of advanced hydraulic support under the conditions of close-packed arrays.
(2) when advanced hydraulic support moves, helix drum contact base plate, helix drum in the case where lifting jack action drives
Rotation drives advanced hydraulic support movement；Advanced hydraulic support carry when, helix drum lifting jack action drive under from
Bottom plate is opened, helix drum is not acted on by roof and floor power when advanced hydraulic support starts carrying.
(3) advanced hydraulic support solves existing advanced hydraulic support push unit by helix drum walking 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.In figure, 1- top beams, 2- columns, 3- stabilization bearings, 4- pedestals,
5- lifts jack, 6- fixed frames, 7- helix drums, 8- power parts.
Fig. 2 is advanced hydraulic support walking manner schematic diagram in tunnel.
Specific implementation mode
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of omnibearing walking advanced hydraulic support, is mainly used for the advanced branch in tailentry road
Shield, including hydraulic support top beam 1, column 2, stable bearing 3, pedestal 4, lifting jack 5, fixed frame 6, helix drum 7, power
Portion 8.Helix drum 7 is arranged in 4 both sides of pedestal, and when advanced hydraulic support needs mobile, column 2 is shunk, and top beam 1 leaves tunnel
Top plate, lifting jack 5 act, and fixed frame 6 is rotated down, 7 contact base plate of helix drum.
Helix drum 7 is synchronized under the action of power part 8 and is rotated clockwise, and advanced hydraulic support moves in parallel to the left；
Helix drum 7 rotates counterclockwise simultaneously under the action of power part 8, and advanced hydraulic support moves in parallel to the right；The spiral shell of both sides
7 side of rotating drum rotates clockwise, and the other side rotates counterclockwise, and advanced hydraulic support moves forward or back；The helix drum 7 of both sides
Fillet movement is then presented in asynchronous rotation and rotating speed difference, advanced hydraulic support.
Such as Fig. 2, advanced hydraulic support is arranged in tunnel both sides when working normally（Lower right advanced hydraulic support is in position
①）, tunnel centre is walkway, and when advanced hydraulic support needs Forward, column 2 is shunk, and top beam 1 leaves back,
It lifts jack 5 to act, fixed frame 6 is rotated down, and 7 contact base plate of helix drum, helix drum 7 synchronizes spiral in the same direction, in advance
2. hydraulic support laterally shifts to tunnel medium position；Then advanced hydraulic support moves forward to advanced hydraulic support group most
3., then 4. advanced hydraulic support is moved laterally to tunnel lateral location for front position, becomes first advanced hydraulic support.It is logical
Above-mentioned move mode is crossed, last advanced hydraulic support originally becomes coming the first of advanced hydraulic support group foremost
Frame advanced hydraulic support solves current advanced hydraulic support push unit and moves repeatedly the destruction caused by back.
Above-described embodiment is that effective embodiment of the present invention is described, and is not limited the range of present aspect
Fixed, under the premise of not departing from the design spirit of the present invention, ordinary engineering and technical personnel is to the various modifications of the invention made and changes
Into, should all fall into claims of the present invention determination protection domain in.
