Abstract
Provided is an anti-falling and buffering cage supporter. Strip holes which are through front and back are symmetrically formed on the left and the right sides, close to the upper portion, of a housing, a sliding block is arranged inside the housing, a plurality of pressure springs are arranged between the bottom of the sliding block and the housing, two open slots are symmetrically formed in the sliding block, each open slot of the sliding block is movably hinged with a supporting claw through a rotating shaft, a gear shaft and a pin shaft are arranged on the sliding block in parallel and simultaneously penetrate arc grooves of the two supporting claws, one ends of two tension springs are respectively connected with one of the supporting claws, and the other ends of the tension springs are connected with the housing. The anti-falling and buffering cage supporter has the advantages of being simple in structure, easy to install and maintain, and especially good in anti-falling function.
Description
Technical field
The present invention relates to the coal mine lifting safety device, be specifically related to a kind of anti-drop buffering tank-supporting machine, belong to safety of coal mines device technique field.
Background technology
In coal production, in order to prevent breaking because pulleying causes steel rope; And the cage that causes the thus safety misadventure of falling and causing, in the safety of coal mines rules, requirement must arrange corresponding anti-dropping safety device, although existing anti-dropping safety device is not quite similar on principle and structure, but, generally have complex structure, I﹠M difficulty; Especially there is the relatively poor defective of anti-fall effect.
Summary of the invention
The object of the invention is to: the existing defects of anti-dropping safety device in existing cage hoisting mechanism, the invention provides a kind of novel anti-drop buffering tank-supporting machine, overcome the existing existing defects of rolling drop-proof cage bracket.
the present invention realizes that the technical scheme that above-mentioned purpose adopts is: described a kind of anti-drop buffering tank-supporting machine, it is by housing, claw, extension spring, slide block, the shelves axle, rotating shaft, stage clip forms, it is characterized in that: described housing is the cuboid class formation, be shaped with symmetrically the strip hole of front and back perforation near the left and right sides of upper position at housing, inside at housing is provided with slide block, some stage clips are set between slider bottom and housing, be shaped with the open slot of two symmetries on described slide block, and the position of two symmetrical openings grooves all the time with housing on slot align, in each open slot position of slide block by a rotating shaft hinged claw actively, be shaped with arc-shaped slot on described claw, the described arc-shaped slot center of circle is identical with the axis of bearing pin, shelves axle and bearing pin are arranged on abreast on slide block and pass simultaneously the deep-slotted chip breaker of two claws, the two ends of two extension springs other end that is connected with claw wherein respectively is connected with housing, under state of nature, one side-prominent slot of claw, and the top of claw is plane, the lower layer inclined plane shape.
Working process of the present invention is: in use, with device of the present invention totally two cages of installing symmetrically through the both sides of route, when causing cage to surpass the extreme higher position of setting when the bont pulleying, the both sides of cage just form compressive state to claw, and two claws are regained and entered in oblong aperture, when cage surmounts the extreme higher position of claw, under the effect of extension spring, claw resets, and cage is caught, the impact strength of spring buffer cage tenesmus further increases safety performance.
Beneficial effect: can be found out by structure of the present invention and principle of work, that the present invention has is simple in structure, I﹠M is easy, especially has anti-fall effect advantage preferably.
