Description
Technical field
This utility model belongs to a kind of coal mine machinery, particularly a kind of is applied to the support removing platform that force piece withdraws。
Background technology
When coal mine work area is removed, the order of equipment returning is generally bunching, elevating conveyor, transporter, coal-winning machine, support。Support is the equipment finally withdrawn in work surface demolishing process, is also the emphasis in work surface demolishing process。Needed when withdrawing support to use shield support, support removing platform and three kinds of equipment mate-assist of winch in the past。Wherein shield support adopts 4000/17/35 type support, need 3 groups, what be usually placed in work surface rolls back and rationalize on triangulation point, rack restoring work process moves along with withdrawing of support, the pan frontward end of shield support and needs are alignd by the outer end withdrawing support, act primarily as support action in the course of the work, it is prevented that top board falls block and hurts sb.'s feelings。Existing support removing platform uses for many years, turning to and the work of upper flatcar of primary responsibility support, is connected with shield support by union joint。Traction work in winch primary responsibility rack restoring process, is arranged in fortune along on triangulation point。
Support to withdraw process as follows: will be connected with removing card chain device fixing on platform by the push-and-pull head withdrawing support first by 26 round-link chains, flexible by support push-and-pull cylinder completes certainly moving of support, by selecting the card chain device of diverse location to complete turning to by removing supporters, by winch towing bracket, the height of 400mm is improved along the inclined-plane removing platform, flatcar and dismounting platform are fixed, continue towing bracket, support is made to be pulled on flatcar, by support peace lock jail, the flatcar that winch will be equipped with support is used to be drawn between the lifting decomposing support, then ferrum road is withdrawn, the push-and-pull cylinder of operation shield support, adjust the position removing platform and shield support, after adjusting, what carry out next pack support withdraws work。
Colliery has been used up which and withdraws support for many years, and along with updating of operation technique, popularizing of underground coal mine mechanization, work efficiency improves constantly, and trouble free service requires constantly to promote, it has been found that above-mentioned dismounting platform in use there is problems in that
1, support moves on dismounting platform, and certainly moved by withdrawing support push-and-pull removing the work that turns to of first half on platform, drawn by drawing hoist removing the work redirecting between flatcar of latter half on platform, in distraction procedure, in order to ensure that support can go up flatcar smoothly, the latter half removing platform is to go up a slope, and which increases the pull strength of drawing hoist, decreases the service life of drawing hoist and steel wire rope。
2, support moves to the mode adopted flatcar for first fixing flatcar from removing platform, then uses drawing hoist towing bracket, is drawn on flatcar by support, in distraction procedure, swipe phenomenon occurs, it is easy to cause wire cable rupture；When support is laid particular stress on flatcar, it is easy to cause flatcar to slide down；During traction, being deathtrap by the region between towing bracket to drawing hoist, All Jobs must stop, and affects job scheduling。
3, inefficiency。When withdrawing support, after a pack support can only being withdrawn from, two groups of shield supports and dismounting platform are moved to specific bit and postpone, the work that withdraws of next pack support, inefficiency can be carried out。
Therefore urgently provide a kind of novel support removing platform at present, meet the rack restoring work of production work。
Utility model content
The purpose of this utility model is to provide a kind of underground coal mine work surface and withdraws the device of support, can improve the work efficiency of rack restoring, is greatly improved particularly in the secure context withdrawing support work。
The purpose of this utility model is achieved by the following technical solution: it includes union joint, push-and-pull thick stick, raised platform, turns to platform I, turns to platform II, card chain device I, diversion baffle, contiguous block I, contiguous block II, push-and-pull cylinder, telescopic component, entrucking seat, card chain device II, plays davit, it is characterized in that: turn to one end of platform I by connecting lug and hinge raised platform；Turn to platform I connection to turn to platform II, turning to platform I one end and turning to one end of platform II to be respectively provided with card chain device I；Fix at the other end turning to platform II and turn to plate washer；
The other end at this device arranges entrucking seat, is respectively provided with lifting post on four angles of entrucking seat, and the tail end at entrucking seat assembles card chain device II；
It is connected telescopic component between platform II with entrucking seat turning to, push-and-pull cylinder telescopic component is set in the both sides of telescopic component outer sliding sleeve is set, slip plug-in mounting inner slide in outer sliding sleeve, outer sliding sleeve is connected with entrucking seat by connection lug and the pin of one end, and inner slide is connected with turning to platform II by connection lug and the pin of one end；Push-and-pull cylinder one end lug of both sides turns to platform II by contiguous block and pin connection, and other end lug is by connecting entrucking seat by contiguous block and pin。
Above-mentioned lifting post arranges the lifting post overcoat being fixedly connected on entrucking seat, assemble, in lifting post overcoat, the sliding inner sleeve that can slide up and down, sliding inner sleeve upper end connects upper binding head, sliding inner sleeve arranges lifting hydraulic cylinder, the lower connection lug of lifting hydraulic cylinder is connected by bearing pin with the attaching clamp of lifting post housing base, and the upper connection lug of lifting hydraulic cylinder is connected by bearing pin with upper binding head。
The inwall of above-mentioned outer sliding sleeve arranges longitudinal boss, inner slide is offered longitudinal notch, the longitudinal notch on inner slide of the longitudinal boss on outer sliding sleeve inwall slides。
Good effect of the present utility model is as follows:
1, safety is high。Comparing with removing platform in the past, and adopted lifting hydraulic cylinder to draw by flatcar on removing supporters, the parameter of hydraulic cylinder is in Table one, and the thrust of single lift cylinders is 48.5T, and making a concerted effort of four lift cylinders is 194T, and crane capacity can fully meet requirement。
Table one: lift cylinders technical parameter
2, work efficiency is high。The support removing platform in the past used, can only once withdrawing a pack support, this device can carry out the work that withdraws of the second pack support while withdrawing the first pack support, withdraw the work of railway also from before 1.5 meters withdraw once, changing 3 meters into and withdraw once, work efficiency is greatly improved。
3, service life of steel wire rope is improved。Removing the structure of platform, when rope traction support for going up a slope, pull strength is big in the past, rope service-life is comparatively short, uses this device, and steel wire rope only draws the support installing flatcar, pull strength is much smaller than before, is therefore greatly improved the service life of steel wire rope。
