Description

The mine hoist rope-adjusting clutch

Affiliated technical field

The utility model belongs to the auxiliary device of mine hoist, relates generally to a kind of mine hoist rope-adjusting clutch.

Background technology

Large-scale bitubular mine hoist is equipped with two reels on main shaft, one of them is fixed on the main shaft, be called dead block, another reel links to each other with main shaft by a rope-adjusting clutch, be called the reel that moves about, so that when needs adjusting work level or hoisting rope length, two reels can produce relative rotation, with the multi level hoisting that adapts to mine and regulate natural elongation in the steel rope use.

Large-scale hoister in using now uses radial gear block type rope-adjusting clutch, its structure as shown in Figure 2, form by oil cylinder 1, piston rod 3, wheel hub 2, shift fork 11, mobile hub 12, connecting plate 13, tooth piece 14, internally toothed annulus 7 etc., move about sliding being contained on the main shaft of hoister of brasses 10 of reel, brasses 10 passes through Bolt Connection together with a wheel 9, the reel disc 8 that moves about, internally toothed annulus 7, and can relatively rotate with main shaft, wheel hub 2 hot chargings are on main shaft, mobile hub 12 is connected with piston rod 3 by shift fork 11, and cunning is contained on the wheel hub 2, connects with tooth piece 14 by connecting plate 13.Fix two oil cylinders 1 respectively at bearing seat both sides (or on support), when pressure oil when the A pipe enters oil cylinder, hydraulic oil promotes piston rod 3 and moves right, make connecting plate 13 promote radially mobile and internally toothed annulus 7 engagements of tooth piece 14 by moving hub 12 with the piston rod bonded assembly, this moment, power-transfer clutch closed, the reel that moves about is connected with main shaft, gig is in normal working, when pressure oil when the B pipe enters oil cylinder, then the A pipe takes back oil sump, hydraulic oil promotes piston rod and is moved to the left, and makes connecting plate 13 promote radially mobile and internally toothed annulus 7 disengagement, the i.e. throw-out-of clutchs of tooth piece 14 by moving hub 12 with the piston rod bonded assembly.Move about reel and main shaft thrown off, and the reel braking of will moving about this moment starts gig, and dead block rotates, because the reel that moves about breaks away from main shaft, then two reels are done and relatively rotated, and can reach the purpose of regulating working level or adjusting rope length.The structure design structure of existing rope-adjusting clutch is comparatively complicated, the intermediate drive link is many, gear back lash is big, so accumulated error is big.Uppity link was many during its structure design made and processes in addition, and the requirement on machining accuracy height is not only transferred rope precision deficiency in the use, also often cause abnormal voice occurring in the gig operational process, influences the safe reliability of gig.

Summary of the invention

The purpose of this utility model promptly is to propose a kind of mine hoist rope-adjusting clutch, makes it have simple in structure, high reliability features, thereby overcomes the existing existing above-mentioned defective of rope-adjusting clutch.

The utility model is finished the technical scheme that its invention task takes: its mainly by oil cylinder, piston rod, stir ring, wheel hub, feather key, external toothing, internally toothed annulus and the reel brasses that moves about, the reel that moves about prop up wheel and form, the reel brasses cunning of moving about is contained on the main shaft of hoister and props up to take turns by the reel that moves about and connects one with the reel disc that moves about, internally toothed annulus; Wheel hub is enclosed within on the main shaft and is connected with external toothing with the main shaft interference fit and by feather key; Stir ring and be contained in the groove of external toothing and the external toothing free-running fit, piston rod encircles screw thread and combines with stirring.

The utility model working process: when pressure oil when the A pipe enters oil cylinder, piston rod moves to the right, ring is stirred in promotion, external toothing moves right on feather key, make the engagement of external toothing and internally toothed annulus, this moment, power-transfer clutch closed, the reel that moves about is connected with main shaft, move about reel and dead block rotates synchronously by main shaft drives, the gig normal operation, when pressure oil when the B pipe enters oil cylinder, then the A pipe takes back oil sump, piston rod is moved to the left, and external toothing and internally toothed annulus is thrown off, i.e. throw-out-of clutch, move about reel and main shaft thrown off, the reel that will move about this moment is braked, and starts gig, and the reel that moves about does not promptly rotate with main shaft, reel and main shaft move about, dead block is done and is relatively rotated, and can reach to regulate working level or adjust the long purpose of rope.

The rope-adjusting clutch that the utility model proposes has following characteristics:

1, simple in structure, the intermediate drive link is few, and accumulated error is little, transfers rope precision height, and clutch is accurate rapidly.

2, adopt the gear ring mesh form, carry-over moment is safe and reliable.
