Description
Technical field
The present invention relates to returning of a kind of coal mine fully-mechanized mining a complete set of equipment and remove device, be specially a kind of fully-mechanized mining working surface hydraulic support beam type and return and remove device.
Background technology
The coal mine fully-mechanized mining hydraulic support is the visual plant in the coal mine fully-mechanized mining a complete set of equipment; Quantity is more; Back production is to stopping adopting the line place, and equipment such as coal-winning machine, scraper plate machine and comprehensive mining hydraulic bracket all need be moved next face to be adopted from a work plane and install, the returning of comprehensive mining hydraulic bracket remove be combine adopt a complete set of equipment return remove in a maximum job of workload; Because gangue, the rock that inbreak is arranged accumulated at the hydraulic support rear; Genus pressure concentrates the visualization area geological conditions abominable, and the fully mechanized coal face hydraulic support returns and leans on winch and rope traction when removing at present, flies to slide because wire rope snaps easily; There is great potential safety hazard; And labour intensity is big, return that the speed of removing is slow, inefficiency, and in a word, aspects such as the safety of present this fully-mechanized mining working rack restoring mode, efficiency all can not adapt to the requirement of resettlement fast of high-yield and high-efficiency fully-mechanized mining working.
Summary of the invention
The present invention returns to remove and mostly adopts winch and rope traction to accomplish in order to solve existing fully-mechanized mining working surface hydraulic support; Have that potential safety hazard is big, labour intensity is big, return the speed of removing waits problem slowly; Provide a kind of fully-mechanized mining working surface hydraulic support beam type to return and remove device, shorten the resettlement non-cutting time of fully-mechanized mining working surface hydraulic support.
The present invention adopts following technical scheme to realize: the fully-mechanized mining working surface hydraulic support beam type returns removes device; Comprise that at least three returning of being arranged side by side remove shield support; Remove shield support said time and comprise base, front rod, back link, caving shield, back timber; Be connected with column between base and the back timber; Run through in the base and pusher rod is set and passes oil cylinder; In passing the hydraulic control system of oil cylinder, be provided with reversible lock, pusher rod one end is with to pass oil cylinder piston rod end head hinged, and innovative point of the present invention is that this beam type returns and removes device and also comprise to return the longeron of removing the shield support outside and be connected in rigid triangle beam type that the raker beam between crossbeam, the longeron constitutes by the crossbeam of removing shield support base the place ahead in each go back to, at avris and return and remove device; Avris returns the chassis outer side of removing shield support and is provided with fairlead, and longeron runs through and is arranged in the fairlead, and longeron is provided with chain regulator, is connected with the chain that is connected with the fully-mechanized mining working surface hydraulic support beetle haulage system on the chain regulator; It is hinged with crossbeam respectively that the pusher rod clutch end of shield support is removed in each time.
In order further to optimize the structure that device is removed in this time, improve its function, the present invention has also carried out following architecture advances:
This beam type returns to be removed device and also comprises with returning and remove the trigonum shield support that shield support was arranged side by side and was positioned at fully-mechanized mining working support one side.
Said crossbeam one end and be positioned at fully-mechanized mining working support one side and be hinged with the crossbeam lengthening beam.The crossbeam lengthening beam can be removed span length and the haulage device width is accepted or rejected according to returning, and in addition, crossbeam and crossbeam lengthening beam are connected to form hinged girder, and vertical direction can swing ± and 15 °, can adapt to certain base plate fluctuating.
Formation rigid triangle beam type returns longeron, crossbeam, the raker beam of removing device and connects through bearing pin in twos, and is conveniently detachable, dismantles when helping the conversion work face, transports and re-assembly.
The present invention be directed to that fully-mechanized mining working surface hydraulic support returns the actual conditions of removing technology under the coal mine; Make full use of the fully-mechanized mining working support and remove the shield support function, set up to return the longeron of removing the shield support outside and be connected in rigid triangle beam type that the raker beam between crossbeam, the longeron constitutes and return and remove device by the crossbeam of removing shield support base the place ahead in each go back to, at avris with returning, with chain longeron with treat that the back withdrawing fully-mechanized mining working face support is connected; With the longeron is anchor point; Utilization treats that the realization of back withdrawing fully-mechanized mining working face support passing oil cylinder moves certainly, and progressively from fully-mechanized mining working, withdraws from, simultaneously; It is fulcrum with crossbeam and crossbeam lengthening beam that shield support is removed in each time; In base, pass under the effect of oil cylinder and pusher rod, step type moves forward one by one, moves to next operating position so that remove the shield support group for whole time.Returning when removing the shield support step type and moving, the rigid triangle beam type returns removes the whole same moved further of device.
Compared with prior art, design concept of the present invention is rationally advanced, compact conformation; Safety and stability is reliable, has replaced tradition such as dependence winch and rope traction fully and has returned and to remove method, can make to treat back removing supporters oneself retracts and removes; Improve face velocity of fully-mechanized mining working rack restoring resettlement greatly, alleviated labor strength, improved production efficiency; Strengthen coal mine production safety property, eliminated potential safety hazard, improve the high-yield and high-efficiency of fully-mechanized mining working; Through practical proof, be that a kind of very good fully-mechanized mining working surface hydraulic support returns and removes device.
