Abstract
The utility model relates to a shaft bottom is strutted with contractible connecting device of I -steel, including two at least landing legs that are used for supporting the I -steel, the I -steel lower part is equipped with sliding plate and short joist, and the length direction translation can be followed for landing leg and sliding plate to the I -steel, and the sliding plate can be for short joist along length direction translation, short joist is connected with the card of falling U -shaped cable, and the both ends card of card cable just is connected with short joist in the both sides of I -steel, the sliding plate is the U -shaped, is equipped with the spacing bolt that prevents the I -steel and shift up on its both sides board when sliding, the length direction of I -steel bottom surface goes up the symmetry and is provided with two stoppers, and this device is particularly useful for using when colliery actual mining roadway adopts I -shaped steelframe canopy to strut, and the contractibility is good, stability is high, it is convenient to dismantle during the back production, can realize the I -steel retrieves fast, helps the coal mine safety high efficiency to produce.
Description
Technical field
The utility model relates to that to be applicable to pressure from surrounding rock large, need H-shaped steel supporting structure possess can contracting yielding property can stope drift active workings supporting occasion, being specially a kind of shaft bottom supporting i iron can contracting linkage.
Background technology
When cannot take bolt support in country rock pore-forming difference, H-shaped steel supporting is optimum support pattern, and H-shaped steel supporting can also recycling in exploitation process.But H-shaped steel supporting is rigid protection mostly, when pressure from surrounding rock is large, because support can not contract, rigid support yield failure must be caused and have a strong impact on surrounding rock stability, and i iron reclaims very also difficulty.
Utility model content
For above-mentioned prior art Problems existing, the utility model provides a kind of shaft bottom supporting i iron can contracting linkage.
The utility model is achieved through the following technical solutions: a kind of shaft bottom supporting i iron can contracting linkage, comprise at least two supporting legs for supporting i iron, i iron bottom is provided with sliding panel and short joist, i iron can relative to supporting leg and sliding panel translation along its length, and sliding panel can relative to the translation along its length of short joist; Described short joist is connected with inverted U-shaped card cable, and the two ends of card cable are stuck in the both sides of i iron, and are connected with short joist; Described sliding panel is U-shaped, and its biside plate is provided with the caging bolt moved on when preventing i iron from sliding; The length direction of described i iron bottom surface is symmetrically arranged with two limited blocks.
The both sides of described short joist arrange installing hole, and the two ends of card cable arrange external screw thread, and the both ends of card cable are inserted in installing hole respectively, and are fixed by nut, and arrange spring shim between the bottom surface of nut and short joist.
There is baffle plate described sliding panel bottom surface near one end of supporting leg end.
Described supporting leg top is provided with U-shaped bearing.
Maximal phase between described sliding panel and card cable is 100 ~ 200mm to sliding distance.
Maximal phase between described limited block and sliding panel is 150 ~ 200mm to sliding distance.
The beneficial effects of the utility model: this device is particularly useful for stope of coal mines tunnel and adopts during i iron shed shoring and use, contractibility is good, stability is high, stoping period convenient disassembly, can realize i iron and reclaim fast, contributes to safety of coal mines High-efficient Production.
