Technical field
The utility model relates to a kind of adjustable force moment anchor nut fastener, belongs to anchor pole fastener technical field.
Background technology
In mechanical coal cutting roadway, for the safety in production of mining continuously, complete bank must be with the fixing top of top anchor pole net.At present, existing anchor nut fastener, does not have relief arrangement, when output shaft overload operation, is easy to the planetary gear of fastener to damage, and more gear changing is frequent, has improved use cost, and service efficiency is lower.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has been to provide a kind of simple in structure, easy to use, can automatic deloading, safe and reliable adjustable force moment anchor nut fastener.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: adjustable force moment anchor nut fastener, comprise body, the bottom of described body is provided with drive sub, the moment input at bodies top center is provided with built up gear axle, on bodies top circumference, be provided with the planetary gear being meshed with built up gear axle, body exterior is provided with ring gear, described planetary gear is meshed with ring gear, on described ring gear, be stamped gland, the bottom of described ring gear is provided with spring base, in spring base, be provided with spring, between described spring and ring gear, be provided with and contact ball, ring gear bottom is provided with the pit corresponding with contacting ball, spring base outer setting has race ring, in race ring, be provided with thrust ball bearing, described ring gear contacts with thrust ball bearing by connecting ring, on described spring base, be also fixed with the detachable arm of force.
On described spring base, be provided with the tight fixed bolt for holddown spring.
Described drive sub is hexagonal structure in hollow.
The beneficial effect that the utility model compared with prior art had is: the utility model is simple and reasonable for structure, can automatic deloading, when output shaft overload operation, can guarantee the idle running of moment input, guarantee that planetary gear and gear ring are not damaged, handling safety is reliable, operate steadily, can a tractor serves several purposes, interchangeability is strong, the in-situ trouble that is easy to simple in structure; Can also adjust output shaft load according to the fastening requirement of different nuts, to meet the fastening requirement of varying strength anchor pole simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model adjustable force moment anchor nut fastener.
In figure: 1 is body, 2 is drive sub, and 3 is built up gear axle, and 4 is planetary gear, and 5 is ring gear, 6 is gland, and 7 is spring base, and 8 is spring, and 9 is contact ball, and 10 is race ring, 11 is thrust ball bearing, and 12 is connecting ring, and 13 is the detachable arm of force, and 14 is tight fixed bolt.
The specific embodiment
As shown in Figure 1, adjustable force moment anchor nut fastener, comprise body 1, the bottom of described body 1 is provided with drive sub 2, the moment input of body 1 top center is provided with built up gear axle 3, in body 1 top circumference, be provided with the planetary gear 4 being meshed with built up gear axle 3, body 1 outer setting has ring gear 5, described planetary gear 4 is meshed with ring gear 5, on described ring gear 5, be stamped gland 6, the bottom of described ring gear 5 is provided with spring base 7, in spring base 7, be provided with spring 8, between described spring 8 and ring gear 5, be provided with and contact ball 9, ring gear 5 bottoms are provided with the pit corresponding with contacting ball 9, spring base 7 outer setting have race ring 10, in race ring 10, be provided with thrust ball bearing 11, described ring gear 7 contacts with thrust ball bearing 11 by connecting ring 12, on described spring base 7, be also fixed with the detachable arm of force 13.
On described spring base 7, be provided with the tight fixed bolt 14 for holddown spring 8.
Described drive sub 2 is hexagonal structure in hollow.
When the utility model is specifically used, adjust tight fixed bolt 14, to adjust the nominal load of output shaft, the hand-held detachable arm of force 13 of exerting oneself, motorized motions built up gear axle 3 rotates, planetary gear 4 is meshed with built up gear axle 3, planetary gear 4 is meshed with ring gear 7, ring gear 7 the detachable arm of force 13 and spring 8 with contact the effect of ball 9 under motionless, in the time of planetary gear 4 autobiography and along ring gear 7 inwalls, roll, thereby the drive sub 2 that drives body 1 and be connected with body 1 is rotated, and carries out the Quick fastening of securing member.
When securing member reaches rated load, spring 8 extruding contact balls 9 compress the pressure of ring gear 7, be not enough to control ring gear 7 motionless, now drive sub 2 and body 1 stop operating, planetary gear 4 continues autobiography, ring gear 7 and connecting ring 12 are dallied, thereby assurance planetary gear and ring gear are not damaged.
Tight fixed bolt 14 holds out against spring 8, by adjusting tight fixed bolt 14, adjusts the nominal load of output shaft, and to meet the fastening requirement of different securing members, practical simple, convenient, handling safety is reliable.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above; but the utility model is not limited to above-described embodiment; in the ken possessing those of ordinary skills; can also under the prerequisite that does not depart from the utility model aim, make obtaining various variations, also should be considered as protection domain of the present utility model.
