Abstract
The utility model relates to a torque amplifier for a jumbolter, and belongs to the technical field of jumbolters. The torque amplifier for the jumbolter comprises an annular gear, a gear shaft and a planet carrier. The torque amplifier for the jumbolter is characterized in that one end of the planet carrier penetrates into the annular gear, the other end of the planet carrier is exposed outside the annular gear, and a ring-shield is arranged at the exposed end of the planet carrier; the end, provided with a gear, of the gear shaft is independently arranged in the planet carrier inside the annular gear; an annular sliding groove is formed in the periphery of the gear shaft; a round pin corresponding to the sliding groove is arranged and fixed on the planet carrier; four planet wheels which are intermeshed with the annular gear and the gear on the gear shaft respectively are evenly arranged on the periphery of the planet carrier; each planet wheel is movably connected with the planet carrier through a shaft pin. By using the torque amplifier, pre-tightening force requirements of anchor bolt nut installation can be met without using a special anchor bolt nut breaker and other special devices any more, therefore, the labor intensity is effectively reduced for workers, and labor efficiency is improved.
Description
Technical field
The utility model relates to a kind of torque amplification for jumbolter, belongs to the jumbolter technical field.
Background technique
While using jumbolter skyhook nut, because the rig rotating speed is high, moment of torsion is little, do not reach the pretightening force requirement, its pretightening force does not often reach the requirement of top board bolting with wire mesh safe design, all need to use special other special devices such as anchor nut loading and unloading device to be installed in addition for this reason at every turn, waste time and energy.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of torque amplification for jumbolter is provided, and it is simple in structure, the pretightening force requirement while having guaranteed to use jumbolter skyhook nut.
Torque amplification for jumbolter described in the utility model, comprise ring gear, gear shaft and planet carrier, it is characterized in that: planet carrier one end is through in ring gear, the other end is exposed at outside ring gear outward, be provided with shaft block ring at the planet carrier exposed junction, one end of gear shaft band gear independently is arranged in the planet carrier in ring gear, offer ring-like chute on the gear shaft circumference, corresponding chute is provided with straight pin, straight pin is fixed on planet carrier, on the planet carrier circumference, evenly be provided with respectively with ring gear and gear shaft on intermeshing four planet wheels of gear, each planet wheel is flexibly connected by pivot pin and planet carrier.
Use for convenient, on described ring gear outer circle wall, be fixed with block, be provided with screw rod on block, screw rod is threaded with block.
In order further the relative block of screw rod to be fixed, be provided with the nut be complementary with it on described screw rod, screw rod is connected with block by nut.
Wherein, on preferred described planet carrier, offer through hole, pivot pin is inserted in through hole, and corresponding pivot pin is expert on the star frame and is provided with door, and door is fixed by slotted countersunk flat head screw and planet carrier.
Compared with prior art, the utlity model has following beneficial effect:
By the utility model, it is simple in structure, during use, in the dop of the jumbolter of only the gear shaft connecting end need being packed into, selects corresponding ut socket to be enclosed within planet carrier moment output terminal, just direct skyhook nut.Due to what adopt, be planetary gear reducing mechanism, it is little that it possesses volume, and reduction speed ratio is large, and the characteristics that driving torque is large, so no longer need to use special other special devices such as anchor nut loading and unloading device, the pretightening force requirement in the time of just can meeting the skyhook nut.The utility model is specially adapted to compare little operational site, space, have lightweight, simple to operate, easy to use, be convenient to the characteristics such as maintenance, thereby effectively alleviated worker's labor intensity, raise labour efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A cross-sectional view in Fig. 1;
In figure: 1, screw rod 2, block 3, nut 4, pivot pin 5, shaft block ring 6, planet carrier 7, planet wheel 8, ring gear 9, door 10, slotted countersunk flat head screw 11, straight pin 12, gear shaft.
Embodiment
Below by specific embodiment, the utility model is described in further detail; but not in order to limit the utility model; all within the present invention spirit and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
As Fig. 1, shown in Fig. 2, torque amplification for jumbolter, comprise ring gear 8, gear shaft 12 and planet carrier 6, planet carrier 6 one ends are through in ring gear 8, the other end is exposed at outward outside ring gear 8, be provided with shaft block ring 5 at planet carrier 6 exposed junctions, gear shaft 12 independently is arranged in the planet carrier 6 in ring gear 8 with an end of gear, offer ring-like chute on gear shaft 12 circumference, corresponding chute is provided with straight pin 11, straight pin 11 is fixed on planet carrier 6, on planet carrier 6 circumference, evenly be provided with respectively with ring gear 8 and gear shaft 12 on intermeshing four planet wheels 7 of gear, each planet wheel 7 is flexibly connected by pivot pin 4 and planet carrier 6.
In the present embodiment, on described ring gear 8 outer circle walls, be fixed with block 2, be provided with screw rod 1 on block 2, screw rod 1 is threaded with block 2, is provided with the nut 3 be complementary with it on screw rod 1, and screw rod 1 is connected with block 2 by nut 3; Offer through hole on described planet carrier 6, pivot pin 4 is inserted in through hole, and corresponding pivot pin 4 is provided with door 9 on planet carrier 6, and door 9 is fixing with planet carrier 6 by slotted countersunk flat head screw 10; Module on described ring gear 8, planet wheel 7 and gear shaft 12 is 1.5; Reduction speed ratio between described gear shaft 12 and planet carrier 6 is 5: 1.
