Background technology
At present, be widely used overhead manned equipment long distance transportation personnel under coal mine, the safe operation of overhead manned equipment is the material particular in safety management always.Overhead manned equipment principle of work is: the annular wire rope of being pegged graft in two ends is arranged on actuating device and return sheave, middle with asking rope sheave, press rope wheel etc. to be fixed, and carries out tensioning by counterweighted take-up.Electrical motor by actuating device during overhead manned equipment work drives reductor to rotate by coupler, reductor drives drive wheel rotation, the steel rope that makes to be wrapped between drive wheel and return sheave is done electrodeless circular flow, or up and down reciprocatingly operation, first chair lift is connected with rope clamping device, again rope clamping device is locked on the steel rope of operation, along with steel rope upstream or downstream, thereby realizes conveying personnel's object.Difference or steel rope reason such as unbalance stress and holder rope sheave surface making precision in operational process due to holder rope sheave setting height(from bottom), position and angle, steel rope can fall rope accident in uncertain position, causes the passenger in chair lift that serious human casualty accident occurs.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of simple in structure, reasonable in design, safe and reliable overhead manned equipment anti-rope falling device, when it can effectively prevent down-hole overhead passenger carrier operation, steel rope deviates to hold in the palm inner edge or the outer rim of rope sheave race, thereby falls the phenomenons such as rope, card rope.
For achieving the above object, the utility model adopts following technical scheme:
A kind of overhead manned equipment anti-rope falling device, it comprises fixed mount, rotating shaft and slide block, and fixed mount is comprised of horizontal plate and diaphragm plate, and diaphragm plate top is welded on horizontal plate bottom surface one side central authorities, horizontal plate two ends symmetry offers U-lag hole, offers a through hole on diaphragm plate; Slide block is comprised of hollow tubular and the riser that is welded on hollow tubular outer wall, and riser bottom is provided with a circular arc cutaway; Rotating shaft one end is provided with catch, and the other end is provided with outside thread; The horizontal plate of fixed mount is connected with the crossbeam of overhead manned equipment by attaching parts, the hollow tubular of slide block is set in rotating shaft, rotating shaft has in the through hole on the diaphragm plate that externally threaded one end is arranged in fixed mount and is fixedly connected with diaphragm plate by nut, the riser of slide block is positioned at directly over steel rope and holder rope sheave contact point, and the circular arc cutaway lower end of riser is close to holder rope sheave both sides.
Described overhead manned equipment anti-rope falling device, the attaching parts that the horizontal plate of its fixed mount is connected with the crossbeam of overhead manned equipment is U-shaped steel.
Owing to adopting technical scheme as above, the utlity model has following preceence:
This overhead manned equipment anti-rope falling device, it is simple in structure, reasonable in design, easy installation and removal, be convenient to transportation, result of use is good, by the U-lag hole on horizontal plate, through hole on diaphragm plate, can make anti-rope falling device carry out respectively adjustment by a small margin at upper and lower and front and back four direction, the horizontal plate of fixed mount is connected with the crossbeam of overhead manned equipment by attaching parts, can make anti-rope falling device significantly adjust at left and right directions along crossbeam trend, to guarantee that anti-rope falling device is accurately in place; Slide block is set in rotating shaft via hollow tubular, the riser of slide block relies on deadweight to hang on directly over steel rope and holder rope sheave contact point, the circular arc cutaway of riser bottom can be in the situation that not contacting steel rope kayser steel rope to greatest extent, guarantee that steel rope can not come off and fall rope accident from holder rope sheave; Slide block can, along rotating shaft swing, not affect chair lift and rope clamping device and pass through from steel rope upper end.
