Abstract
The utility model relates to an inclined top laneway advance timbering horizontal forward bracket which adopts a lifting rod to substitute a cover beam to be hinged with a top beam, the lifting rod is inserted in a fixing trough of a base, and the lift is controlled by a jack to fit the change of height of a laneway; an upright post is supported between the base and the top beam in an inclined mode; the top beam fits the change of a support inclined top laneway top plate and an inclination angle; the fixing trough of the base bears lateral component of a rock top plate transferred from the top beam and the lifting rod; the top beam can not slip upwards and broadways along the laneway inclined top plate, and so the bracket stably and effectively timbers the inclined rock top plate; and the upper part and the lower part of the top beam are both provided with lateral protecting beams controlled by spring components, guided support shafts and the jacks, and the top protection area is enlarged. The inclined top laneway advance timbering horizontal forward bracket can solve and satisfy urgent requirement of coal mine high-yield high-efficiency composite mechanical coal mining to inclined top laneway fast advance stable timbering and safe production, and can promote greater development of coal mine composite mechanical coal mining.
Description
Technical field
The utility model relate to a kind of coal mining mechanization produce in the advance support in the oblique top tunnel support that laterally moves forward.
Background technology
Along with the coal mine machinery coal mining, particularly combine the development adopt, the quick and safe advance support problem of support in gateway of coal mining face (comprising machine lane and air way) is highlighted.Usually the supporting ratio in flat-top tunnel is easier to solve, but oblique top lame advanced supporting difficulty is more, and especially difficult point of supporting laterally moves forward.The support that generally is used for the flat-top tunnel can not solve an oblique top stability of the roadway supporting difficult problem, mainly be that set cap supports making progress to the component of side of oblique top generation, cause back timber upwards to side slip, make the ability of support loss of stability and supporting oblique top plate, can not solve the advance support and the horizontal reach problem in oblique top tunnel, greatly influence and restrict the development of comprehensive quick and High-efficient Production of adopting.Therefore, be badly in need of the hydraulic support of development oblique top lame advanced supporting and horizontal reach at present, to adapt to the demand that coal mine fully-mechanized mining is stablized supporting in advance and laterally moved forward safely the oblique top tunnel.
The utility model content
At above-mentioned situation, the purpose of this utility model just provides a kind of oblique top lame advanced supporting support that laterally moves forward, an effective difficult problem that solves the oblique top lame advanced supporting and laterally move forward guarantees that comprehensive quick propelling of adopting is to oblique top the tunnel synchronous advance support and the safety requirements of (comprising machine lane and air way).
The technical solution of the utility model is as follows:
This oblique top lame advanced supporting support that laterally moves forward is the length of screening as required, form side arm and after-frame by a plurality of basic framves, and by passing the basic combined frame structure that jack is connected to form, before and after between frame by thrust gear make its not by external force and front and back laterally from moving, front and back frame width basis is gone into the well and traffic condition is decided, need to strengthen the shielding length of advance support, can increase the front and back frame number of composition.
Described basic frame includes back timber, column, base, elevating lever and support jack; Replace caving shield and back timber hinge with elevating lever, the elevating lever upper end is hinged with back timber, and insert in the holddown groove of base the elevating lever lower end, controls lifting by jack, adapts to the tunnel and just changes; Described column diagonal brace is between base and back timber, and back timber supports the inclined gallery top board and appropriate angle changes (15 °～60 ° of excursions).Like this, the base holddown groove bears the cross component force that top board comes through back timber, elevating lever transmission, and back timber can not make the stable and effective support inclination rock top board of support along the oblique top plate upwards to side slip.
To protect top area in order enlarging, also to be provided with upper and lower extensible canopy at the two ends of described back timber, be connected at two ends up and down with back timber by the upper and lower extensible canopy jack and the upper and lower spring axis of guide, control is flexible.
The advance support that the utility model is mainly used in fully-mechanized mining working oblique top tunnel (comprising machine lane and air way) laterally moves forward, and its advantage is as follows:
1, be hinged by elevating lever and back timber, elevating lever inserts in the base holddown groove, by jack control lifting, adapts to the tunnel and just changes.
2, the column diagonal brace is between base and back timber, and back timber adapts to top board inclination angle, inclined gallery and changes (15 °～60 °).
3, the base holddown groove bears the cross component force that the rock top board comes through back timber, elevating lever transmission, and back timber can not make the stable and effective support inclination rock top board of support along the oblique top plate upwards to side slip.
4, respectively establish the extensible canopy of controlling by spring assembly, guiding back shaft and jack up and down by back timber, can enlarge inclined gallery and protect top area.
5, according to the down-hole traffic condition, every pack support and member thereof are unsuitable wide long, adopt the versatility technical measures, by many combinations arbitrarily of identical basic frame, adapt to the requirement of lame advanced supporting length, and interchangeable direction are used.
6, the advance support in the oblique top tunnel support that alternately moves forward, substantially the advance support in oblique top tunnel and a difficult problem that laterally moves forward have been solved, effectively satisfied to combine and adopted, coal mine machineryization has been combined the mining height product efficiently will play guaranteeing role with the safety in production development to the advance support in oblique top two lanes and the requirement of horizontal reach safely.
