Abstract
The utility model relates to a prop pulling hoist adopting a duplicate gear, which is characterized in that an explosion-proof motor (1) is connected with a bevel pinion (3) and a large bevel gear (4) by an elastic coupling (2); the large bevel gear (4) is connected with a gear I (5), a duplicate gear I (6), a duplicate gear II (7), a gear II (8), a gear III (9) and an idle gear (10) in sequence by a circuit; the idle gear (10) is connected with a gear wheel (11), a winding drum (12) and an attachment bolt (13) in sequence by a circuit; and two duplicate gears replace a worm gear for realizing high transmission ratio. The prop pulling hoist has the following benefits: the range of time-variant load and driving moment is large, the required speed adjustment is convenient, the operation at high and low speed is stable, the requirements on safety and reliability are higher, and the operability is required to be better.
Description
Technical field
The utility model relates to a kind of drawing hoist that adopts dual gear, particularly is widely used in a kind of winch of various occasion.
Background technology
Winch is a kind of common machinery in the industrial process, has the long developing history and the design and manufacturing technology of comparative maturity.Along with updating and the continuous development of electron controls technology of the improving constantly of winch manufacturing technology, work material, winch has been made significant headway at aspects such as power, energy-conservation and safetys.At present, winch is just applied to numerous areas such as mine, harbour, factory, building and ocean widely.In mine excavation and transportation occasion, winch is being used in a large number and widely as important accessory equipment, for example mine lift winch, car hauler, Rabble mine winch and sinking winch etc.Lifting winch can be used for the scheduling of article and personnel in vertical shaft for mine or the inclined shaft, has bigger tractive output and well safety, is one of indispensable equipment during the mine produces.
Another important use of winch is a harbour machinery, and common have container handling crane, harbour handling span winch, tower crane and small-sized elevator machineries such as hoist ceiling crane, and its main actuating unit all is the winch of various forms and structure.For the winch of this purposes, require to possess speed adjusting performance and very high safety performance preferably.In addition, winch is also applied to storage, manufacturing and the transportation of various cables, and for example being used in the textile machine deposited the drum of silk thread and the cable dish that cables manufacturing is used to deposit various diameter hawsers.In this case, winch not only will have certain speed governing ability, but also can make the hawser marshalling of different-diameter, thereby guarantees carrying out smoothly of production.In marine deck machinery and ocean exploitation field, winch also has the historical and diversified purposes of long use.
We can say that winch applies to various occasions widely, bringing into play different effects, also have various structures and form.For structure and the performance of studying winch better, need launch to inquire into to the composition of winch and the classification of winch.
The utility model content
The technical problems to be solved in the utility model provides a kind of drawing hoist that is applicable to a kind of dual gear of various occasion.
Keystone configuration characteristics of the present utility model are: fire proof motor is connected with bevel pinion, bevel gear wheel by elastic coupling, bevel gear wheel is connected with gear I, dual gear I, dual gear II, gear II, gear III, idle pulley successively by circuit, and idle pulley connects big gear wheel, reel, attachment bolt successively by circuit.
The beneficial effects of the utility model are: become during load, the drive torque scope is big, requires that speed governing is convenient, high low speed is stable, and safe reliability is had relatively high expectations, and requires to have better operability.
Description of drawings:
Accompanying drawing is transmission principle figure of the present utility model
The specific embodiment
The utility model is described in further details the drive path of this driving system below in conjunction with accompanying drawing and the specific embodiment: electrical motor 1 → elastic coupling 2 → bevel pinion 3 → bevel gear wheel 4 → gear 5 → dual gear 7 → dual gear 6 → gear 8 → gear 9 → idle pulley 10 → big gear wheel 11 → reel 12, bevel-gear pair transmission drawing hoist makes full use of gear transmission motion and power, and 2 dual gears adopt antifriction-bearing box to connect with 2 axles respectively; 2 dual gears do not rotate with axle, and 2 axles play a supportive role to it, like this, sense of motion takes place 3 times and changes from the II axle to the III axle, changed gear and placed side by side the formula type of drive, can realize big transmitting ratio in less spatial dimension, retarder has been realized the full-depth tooth transmission.Its innovative point is to replace worm and gear to realize big speed ratio with 2 dual gears.
Claims (1)
