Description
Technical field
The present invention relates to a kind of colliery and use hydraulic support equipment, relate in particular to a kind of linked roof bar gliding hydraulic bracket system.
Background technology
Termination and crossheading supporting always are the emphasis and the difficult point of safety coal mining about the coal-face; Present coal-face both domestic and external termination and crossheading supporting mainly contain two kinds of forms: the one, and the supporting of automatic moving type face end support, the 2nd, towering beam of single-column or single-column hinge beam combined supporting.Wherein the automatic moving type face end support is bulky and heavy, the pedestrian space is little, transport and install all very difficulty, and therefore, this mode is not adopted or seldom adopts in most of colliery; The towering beam of single-column or single-column hinge beam combined supporting formal cause its flexibly, convenient, low cost and other advantages and being adopted by most of colliery, but this mode operation sequence is complicated, labour intensity is big, has a strong impact on the performance of coal excavation apparatus ability and the raising of production efficiency.Simultaneously, this mode safety is relatively poor relatively, and general accident is more.How not only safety but also the termination and the crossheading supporting that solve coal-face efficiently are the technical barriers that perplexs Safety of Coal Mine Production always.
Suspension moving hydraulic support is the intermediate products between above-mentioned two kinds of support patterns; It had both had self-advancing support good integrity, moving property and safe advantage certainly; Also have simultaneously the towering beam of single-column simple with the hinge girder construction, move flexibly, control the big advantage in space, since releasing, be known as the basic mode that effectively solves face end or roadway support under the present technical condition by the colliery always.Because suspension moving hydraulic support self do not have the chassis, can avoid conflicting, thereby the equipment that can guarantee the position, termination has enough layouts and space for maintenance with termination equipment is installed, again can with the same moved further of coal excavation apparatus in the work plane.Need overcome " bowing " phenomenon in the desirable hydraulic support moving process; The phenomenon of " bowing " be since hydraulic support in moving the frame process; The reach part that takes the lead in lacks effective support in the process of protracting; Run-off the straight earthward under the roof pressure effect; Because this reach part produces certain gradient with the expection reach direction of hydraulic support, and can't correct the gradient that is caused from the top board immense pressure through the supporting role of later stage machinery, this will cause moving frame work and can't continue subsequently;
Because in the actual condition, top board is not smooth, hydraulic support need provide effective support to irregular top board;
In addition; Hydraulic support also need overcome problem on deformation when roof supporting: because traditional hydraulic support is for being rigidly connected; And the top board in the actual job process is not smooth, causes hydraulic support in the process of roof supporting, often to deform because of unbalance stress.
For solving the problem of " bowing "; CN201025054Y has proposed a kind of lift-moving type linked roof bar hydraulic support; Comprise beam body and pillar; The beam body comprise a word beam with by Zuo Liang, right beam and be connected at least one of left and right beam and connect the U-shaped beam that crossbeam is formed, left and right beam is with to be connected crossbeam integrally welded.Because left and right beam is with to be connected crossbeam integrally welded, left and right beam be connected between the crossbeam and can't relatively move, a word beam is connected through the passing jack with the U-shaped beam.On a U-shaped beam and a word beam, be provided with the guide and limit structure; The guiding gusset that this lead position limiting structure comprises the limited block on the connection crossbeam that is arranged on the U-shaped beam and is arranged on the said left and right beam inboard and the word beam outside; Said guiding gusset matches with described limited block, so that left and right beam or the mobile of word beam are led.When moving frame, a word beam serves as to support the reach that takes the lead in the U-shaped beam, in the reach process, limits because a word beam receives the position of guide and limit mechanism, can prevent " bowing " phenomenon preferably.In addition, it is not loaded down with trivial details that the hydraulic support of this structure moves frame work yet, only need a word beam and U-shaped beam be supported mobile getting final product each other, do not have the extra connection crossbeam that moves separately of needs.
But, because the left and right beam of such support makes left and right beam must be in same level height with to be connected crossbeam integrally welded.When running into top board not at ordinary times, can't play effective support; In moving the frame process, because a word beam and U-shaped beam stress are inhomogeneous, make that easily guiding gusset and limited block deform under roof pressure, finally cause hydraulic support can't continue to move frame.
For solving the problem of hydraulic support to uneven top plate supporting and support intensity; CN201103399Y disclose a kind of with before and after drag the suspension moving hydraulic support of beam; Drag beam to adopt compression spring device to be suspended on the back timber below before and after it, this compression spring device is made up of built-in cylindrical compression spring of spring spool and connection bearing pin.The hydraulic support of this structure is because at back timber and drag compression spring device is set between beam, can play effective support to ceiling not.Simultaneously, in the process of moving frame and roof supporting, also can play certain cushioning and protection, avoid hydraulic support to produce distortion because of pressurized is uneven hydraulic support.But the frame work that moves of such hydraulic support is comparatively loaded down with trivial details, will serve as to support this hydraulic support is moved forward one by one with adjacent hydraulic support at first, after all hydraulic support is moved into place, also needs will be used to connect the connection crossbeam reach of each hydraulic support.These the two spacing broads that connect crossbeam often are arranged with two in parallel and connect crossbeam, if will cause hydraulic support single forward pitch from shorter; Otherwise, if narrower, then when hydraulic support receives the immense pressure from top board because of reach,,, and certainly lead to " bowing " phenomenon again less than the effective support that connects crossbeam because its bottom is unsettled, cause the follow-up frame work that moves to carry out.In addition, be not integral body owing to be used to connect the connection crossbeam of adjacent hydraulic support, but segmentation combine, this also will inevitably influence the globality and the stability of hydraulic support.
In addition; CN1067479A discloses a kind of hydraulic prop for moving suspended top beam; This hydraulic support includes girder, Zuo Fuliang, right three back timbers of beam of paying, and passes through the elasticity quadric chain between girder and the left and right pair of beam, but the oil cylinder of taking a step to advance of hinged synchronization action respectively.Such support can be done corresponding swing according to ceiling not; Thereby realize the not support of ceiling; Also can solve " bowing " problem to a certain extent; But, when running into not ceiling, need adjust left and right pair of beam, complex operation respectively because its girder is connected respectively through the elasticity quadric chain with left and right pair of beam.
Above-mentioned three kinds of suspension moving hydraulic supports can only solve in the following problems, can not solve following two problems simultaneously:
1, hydraulic support in moving the frame process " bowing " phenomenon and to move frame work loaded down with trivial details;
2, hydraulic support deforms because of receiving the top board immense pressure in moving the frame process, and can not keep smooth after moving frame, can't realize the not support of ceiling.
CN201025054Y and desirable hydraulic support are the most approaching; Because it is through the limited block on the connection crossbeam that is arranged on the U-shaped beam and be arranged on the firm and hard position guiding of moving in the frame process of left and right beam guiding rib inboard and the word beam outside at present; Moving in the frame process limited block slides in the guiding gusset; Can solve " bowing " problem to a certain extent, if but can't provide to imitate to ceiling not and support and problem such as hydraulic support is yielding for solving it, the elastic construction among the CN201103399Y between guiding gusset and limited block, introduced; Then can break and change its mutual fit structure, it can not be moved according to the mode of setting.Equally, still keep smooth after making the disclosed technical scheme of CN1067479A realize moving, then need use the U-shaped girder construction of CN201025054Y, in fact, not only used to connect crossbeam but also use four-bar linkage structure can't realize technically.
In addition, because the path in face tunnel, termination is not straight, therefore move in the frame process and also need move the frame direction, and the above-mentioned hydraulic support of mentioning all can't addresses this problem according to the different directions adjustment in path at hydraulic support.CN1067136C discloses a kind of steering hydraulic support; By back timber, propelling oil cylinder, hydraulic prop; And two groups formed around the property quadric chain, and wherein a side of one group of quadric chain is provided with the upright fork with two long arc-shaped holes, and with slide block, go up connecting rod, bearing pin and location-plate and form upright pendulum sliding-block linkage; When support is advanced; A back timber roof supporting, another back timber changes the spacing of its rear end and supporting top beam through upright fork swing, thereby reaches the purpose that automatic adjusting moves the frame direction.This support is owing to adopted two frame structures; When a back timber roof supporting; When half unloading of another back timber moves frame, the less stable of hydraulic support, upright pendulum sliding-block linkage hour can operate as normal at roof pressure; Complicated or receive roof pressure when excessive when operating mode, this structure can't realize moving normally frame transfer to.
Summary of the invention
Technical problem to be solved by this invention be existing hydraulic support can't solve simultaneously move in the frame process hydraulic support owing to receive roof pressure produce " bowing " phenomenon, can't to ceiling not provide imitate support, hydraulic support receives differential pressure and is out of shape and moves problems such as frame work is loaded down with trivial details.
