Description
Technical field
The present invention relates to a kind of instrument, particularly the instrument of fastening nut on the back under coal mine.
Background technology
Along with the continuous development of society, productivity is improved constantly, and the mechanized operation level under the coal mine is more and more perfect; Various supporting facilities are more and more advanced; Thereby use various metal connector member also more and more, the installation of metal connecting piece needs a large amount of bolts that use, for guaranteeing that downhole safety needs regularly to carry out fastening to nut; Owing to can not use electric tool, still lean on artificial use spanner or sleeve operation now basically.Very inconvenience especially is installed on back, because the space is high, the workman need offer sb. a chance to remedy a fault gracefully and climb up and could operate, and climbs up continually and climbs down ladder, not only wastes the plenty of time, has also increased unnecessary labour intensity to the workman.
Summary of the invention
The nut fastener that the purpose of this invention is to provide a kind of high efficiency, reduces labor intensity.
Technical scheme of the present invention is: comprise sleeve, also comprise pedestal, cover plate, gear train and fixed arm; Said gear train is made up of a driving wheel, two driven stepped gears and an output gear, and driving wheel and output gear shaft cooperate, the pinion of driven stepped gear and output gear engagement, the gear wheel of driven stepped gear and driving wheel engagement; Tooth axle one end of driven stepped gear is positioned on the bearing block on the base side boards, and the tooth axle other end is positioned on the bearing block on the cover plate; Tooth axle one end of driving wheel is provided with six side's shrinkage pools, and this end is positioned at the axis hole on the base side boards, and the tooth axle other end penetrates in the axis hole of output gear, and the other end of output gear is arranged in the axis hole of base side boards, and this end is provided with six side's shrinkage pools; The link of sleeve is provided with six side's boss, and the link of sleeve is inserted in the sleeve pipe in the base side boards outside, and six side's boss on the sleeve link are embedded in six side's shrinkage pools on the output gear axial end, and the working end end face of sleeve is provided with six side's shrinkage pools; The air drill connecting rod is a hexahedron, and air drill connecting rod one end is provided with six side's boss, and this six sides boss is embedded in six side's shrinkage pools on the axial end of driving wheel; Cover plate and pedestal are spirally connected and are one; The pedestal lateral surface is provided with free bearing, and an end of fixed arm is hinged through bolt and free bearing, and the other end of fixed arm is provided with yoke, and yoke is provided with bolt hole.
The output and the sleeve of output gear are structure as a whole.
Owing to adopt the structure of sleeve, gear train and air drill connecting rod among the present invention, the air drill connecting rod is packed on the air drill, the workman stands in and just can utilize air drill to carry out the operation of fastening nut on the ground, does not operate and need not offer sb. a chance to remedy a fault gracefully to climb up to climb down with plank or sleeve.Not only high efficiency has also been saved the arduous of frequent cat ladder.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the STRUCTURE DECOMPOSITION sketch map of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain, but do not constitute any restriction of the present invention.Illustrated in figures 1 and 2, the present invention includes sleeve 3, pedestal 1, cover plate 5, gear train and fixed arm 8.Said gear train is made up of a driving wheel 7, two driven stepped gears 2 and an output gear 6, and the effect of gear train is the power with air drill connecting rod 4 inputs of rotation at a high speed, converts the outputting power of low speed rotation into. Driving wheel 7 and 6 cooperations of output gear.The pinion of driven stepped gear 2 and output gear 6 engagements, the gear wheel of driven stepped gear 2 and driving wheel 7 engagements.Tooth axle one end of driven stepped gear 2 is positioned on the bearing block on pedestal 1 side plate, and the tooth axle other end is positioned on the bearing block on the cover plate 5.Tooth axle one end of driving wheel 7 is provided with six side's shrinkage pools; This end is positioned at the axis hole on pedestal 1 side plate, and the tooth axle other end penetrates in the axis hole of output gear 6, and cooperates with this axis hole rotation; The other end of output gear 6 is arranged in the axis hole of pedestal 1 side plate, and this end is provided with six side's shrinkage pools.The link of sleeve 3 is provided with six side's boss; The link of sleeve 3 is inserted in the sleeve pipe in the pedestal 1 side plate outside; Six side's boss on sleeve 3 links are embedded in six side's shrinkage pools on output gear 6 axial end, are simplified structure, and output gear 6 also can be made of one with sleeve 3; The working end end face of sleeve 3 is provided with six side's shrinkage pools, and the fastening nut of this shrinkage pool and desire is corresponding.Air drill connecting rod 4 is a hexahedron, and air drill connecting rod 4 one ends are provided with six side's boss, and this six sides boss is embedded in six side's shrinkage pools on the axial end of driving wheel 7.Cover plate 5 is spirally connected with pedestal 1 and is one.Pedestal 1 lateral surface is provided with free bearing, and an end of fixed arm 8 is hinged through bolt and free bearing, and the other end of fixed arm 8 is provided with yoke, and yoke is provided with bolt hole.
During work, replace the air drill drilling rods to be contained on the air drill air drill connecting rod 4, the yoke of fixed arm 8 is fixed by bolts on the air drill shell, prevent the disengaging of mining nut fastener of the present invention and air drill, play the purpose of safety in production.Six side's shrinkage pools on the sleeve 3 working end end faces are entangled nut, the work of Push switch air drill, air drill is delivered to sleeve 3 with power through gear train through air drill connecting rod 4, and sleeve 3 is fastening with nut by the power of rotation.Because air drill connecting rod 4 can be done longlyer, need not offer sb. a chance to remedy a fault gracefully and just can operate on the ground, has not only improved operating efficiency, has also alleviated working strength of workers.The operation principle of gear train is known by those of ordinary skill, is not described in detail in this.
