Abstract
The utility model comprises an input shaft, an output shaft, a big gear, a pinion gear, a conical friction clutch rotary bowl, a rotary drum, an output shaft gear, an inner gear ring, a reel drum, a brake block and a machine frame. The pinion gear which is connected with the input shaft is engaged with the big gear of the output shaft, and the conical friction clutch rotary bowl and the rotary drum are connected with both the big gear and the output shaft; the output shaft gear is connected with the inner gear ring which is fixed in the reel drum, and the brake block is connected with the machine frame which is provided with a plurality of supporting positions for supporting the output shaft and the input shaft. The utility model has the advantages of simple and reasonable structure, sensitive and reliable manipulation and small moment of a flywheel for the reel drum; the utility model also has the advantages that the destruction of reversal accelerating dynamic load can be decreased, and the conical friction clutch can satisfy the sensitivity requirement and service life when the percussion frequency of a drilling tool is higher.
Description
The utility model relates to a kind of rig winch, belongs to and creeps into field of mechanical technique.
At present, the built-in differential planetary mechanism of domestic its reel of rig winch, with manipulating handgrip difference fixed carrier or internally toothed annulus, the realization reel drives or stops.Owing to the built-in internally toothed annulus of reel, satellite gear, pinion carrier, center gear, center shaft etc., the driving system moment of flywheel is big, and the required moment of inertia that overcomes of brake drum is also big, to the used load braking potential is reduced.Use to dash when grabbing drilling tool, because the influence of acceleration of free fall, reel quickens, the reverse speedup transmission of deceleration transmission in the reel abdomen, and the planetary mechanism of speedup transmission will be under the abominable situation of dynamic load operating mode, fault rate is improved should not dash to grab creep into.
The purpose of this utility model is the deficiency that overcomes in the above-mentioned existing rig winch technology, and it is little to design a kind of reel moment of flywheel, manual dexterity, and structure is simpler more reliable, the rig winch of the wider model of comformability.
The utility model comprises input shaft, miniature gears, big gear wheel, taper friction clutch rotating cylinder, rotary drum, output shaft, output shaft gear, internally toothed annulus, reel, brake shoe, frame, input shaft links to each other with miniature gears, miniature gears and the engagement of output shaft big gear wheel, big gear wheel links to each other with taper friction clutch rotating cylinder, rotary drum, taper friction clutch rotating cylinder, rotary drum link to each other with output shaft, output shaft gear links to each other with internally toothed annulus, internally toothed annulus is fixed in the reel, brake shoe links to each other with frame, has some to take advantage of the position to support output shaft and input shaft on the frame.
Realize that the utility model purpose groundwork is, utilize a pair of external tooth engaging tooth wheel set and a pair of internal gear pair to carry out double reduction, have the taper friction clutch can clutch therebetween.Because transmission is simple, the reel moment of flywheel is little, oppositely quickens the dynamic breaking reduction.Use the taper friction clutch in addition, can satisfy the sensitivity of impact drilling tool frequency when higher and require and service life
Below in conjunction with accompanying drawing the utility model embodiment is described in detail:
Fig. 1 is the utility model rig winch structural representation.
Fig. 2 is the utility model rig winch drive path scheme drawing.
As depicted in figs. 1 and 2, input shaft 1 links to each other with miniature gears 2, miniature gears 2 and 3 engagements of output shaft 6 big gear wheels, big gear wheel 3 links to each other with taper friction clutch rotating cylinder 4, rotary drum 5, taper friction clutch rotating cylinder 4, rotary drum 5 link to each other with output shaft 6, and output shaft gear 7 links to each other with internally toothed annulus 8, and internally toothed annulus 8 is fixed in the reel 10, brake shoe 9 links to each other with frame 11, has some supportings position to support output shaft 6 and input shaft 1 on the frame 11.During energized and the capable input shaft that connects 1 rotation of engine, Drive pinion 2 and big gear wheel 3 are carried out the one-level deceleration transmission, big gear wheel 3 is synchronized with the movement with taper friction clutch rotating cylinder 4, and taper friction clutch rotating cylinder 4 can or separate with rotary drum 5 combinations, and rotary drum 5 links to each other with output shaft 6.When rotary drum 5 combined with taper friction clutch rotating cylinder 4, output shaft gear 7 and internally toothed annulus 8 engagements drove reel 10 and carry out double reduction.Handle the clutch handle of rotary drum 5, make rotating cylinder 4 and rotary drum 5 in conjunction with or separate, realize drilling tool lifting or whereabouts, can handle brake shoe 9 during emergency braking and realize the reels braking.The supporting of input shaft 1 and output shaft 6 places on the frame 11.
The utility model has the advantages that simple and reasonable, it is reliable to handle sensitivity, the reel moment of flywheel is little, oppositely adds The destructive reduction carried in quick-action, owing to adopted the taper friction clutch, satisfied the spirit when the impact drilling tool frequency is higher Sensitivity requires and service life.
