Abstract

The utility model provides a miniaturized speed regulating mining lifter, that is a planet speed regulating mining lifter which is manually controlled and mechanically braked. The planet speed regulating mining lifter adopts a single-stage planetary differential gear speed reducing mechanism with a floating gear and a service braking brake which acts on the outer gear surface of a planet internal gear which is taken as the housing. Through the cooperation of the single-stage planetary differential gear speed reducing mechanism and the service braking brake, the speed reduction and the speed regulation are realized. When speed is regulated, the friction resistance or the braking force between the single-stage planetary differential gear speed reducing mechanism and the service braking brake is manually controlled, and the speed of the internal gear is changed. The planet speed regulating mining lifter has the advantages of steady operation, no spark, small size, convenient installation and convenient maintenance. As the utility model is matched with a small power electric motor to use, the cost is low. The utility model is particularly suitable for small mining places or the occasions of small operation areas.

Description

Planet speed regulating mining lift

The utility model is a kind of improved winch, particularly a kind of miniaturization mining elevator that is used to draw and/or promote mine car.

The minimum gauge of the present similar mine lift winch of producing, drum diameter is 0.8 meter, as the JT-0.8 type winch of Jinzhou and the production of Chongqing coal mine machinery factory.This winch uses general drop-gear box and resistance step-down deceleration speed governing, and volume is big, cost is high, energy consumption is also big.

The purpose of this utility model provides a kind of mining elevator that can overcome above-mentioned deficiency, adopt planetary gear speed-reduction and manual mechanical braking speed governing.

The technical solution of the utility model provides in the following manner: gig comprises support, with the roll device that is installed in electrical motor, speed governing speed reduction gearing, driving gear, With a driven gear, brake wheel and hauling rope on the support, insurance damper brake, it is characterized in that said speed governing speed reduction gearing is made up of planetary differential retarder and the service braking lock that is used with it, the planetary differential retarder is arranged between electrical motor and the driving gear, the service braking lock is arranged on the next door of the outer wheel face of planet inner gear, and And cooperates with this face.The service braking lock is except that with the manual control, also can use hydraulic pressure or other modes instead and control system and stop.

Planetary wheel in the planet speed governing speed reduction gearing is more than three or three, and divides equally laying by circumference.

The centering gear that is located at the planetary wheel middle part is the turriform spur gear wheel, by the motor engaging gear engagement on float tooth cover and the motor reel, transmitting torque.

Advantage of the present utility model:

1, adopt the planet regulating mechanism, cooperate with the service braking lock, realized mechanical speed governors, operation of equipment is convenient and reliable, starts steadily.Mine car slippery phenomenon out of control can not take place in the work.

2, energy-conservation.Compare with existing product JT800 * 600-30 of similar specification, tractive force is basic identical, but the motor power (output) of adapted can reduce 1/3rd, promptly drops to 15KW from 22KW.

3, volume reduces, and cost reduces, and installation and maintenance are convenient.

4, behind adapted fire proof motor and the flame-proof switch, be more suitable for occasion in borehole operation.

Embodiment accompanying drawing of the present utility model is as follows

Fig. 1 is the structural representation of gig;

Fig. 2 is the planetary speed regulating device diagram of gears;

Fig. 3 is one of satellite gear train scheme drawing;

Fig. 4 is two of a satellite gear train scheme drawing.

Be described further below in conjunction with accompanying drawing

With reference to Fig. 1, direct mount has drum shaft 5 on support 1, insurance damper brake 7, driving gear 10, planetary reduction gear 9, service braking lock 8 and electrical motor 6; The center of driving gear 10 is axially consistent with electrical motor 6, and parallel with drum shaft 5; Driven gear 2, reel 3 and brake wheel 4 are housed on the drum shaft 5, driven gear 2 directly meshes with driving gear 10, twine dress hauling rope 11 on the reel 3, hauling rope connects pulls mine car, car belt brake mode is adopted in the insurance braking, insurance damper brake 7 cooperates with brake wheel 4, and its operator is being installed in the rear of gig by the connecting rod switching so that operation.

Fig. 2 has represented planetary speed regulating device mechanism and transmission situation, and this planet speed regulation device is a kind of single-stage planetary gear reducer with floating gear, and this routine transmitting ratio is 8.

Pinion carrier 12 outsides are connected with driving gear shaft in the casing, three (also can more than three) uniform planetary wheels 14 are housed on the pinion carrier, planetary wheel 14 is meshed with the internal tooth of planet inner gear 13, the centre of planetary wheel 14 is provided with intermeshing centering wheel 15, centering wheel 15 is a cylinder turriform gear, and the engaging gear of its big end and the motor engaging gear 17 on the motor reel connect by the tooth cover 16 that floats.

Behind the motor start-up, motor reel drives motor engaging gear 17, through the tooth cover 16 that floats, centering wheel 15 also and then rotates, because the centering wheel rotates, make and be contained in pinion carrier head bearing bonded assembly satellite gear 14 and also rotate: if inner gear 13 by 8 lockings of service braking lock, then will drive pinion carrier 12 and move, driving gear 10 is also just rotated by drive; If inner gear 13 emptying are then done relative motion between satellite gear 14 and the inner gear 13, and to the not influence of driving gear 10 residing whether locked states.

This shows that during motor operation, reel 3 rotates or gig work is under the prerequisite that brake wheel 4 loosens, and is established under the state of the non-complete emptying of inner gear 13 And.Do not allow to occur two damper brakes when therefore, gig is worked and all be in the state of braking simultaneously.Can both accomplish this point with manual control or mechanical interlock mechanism.

Fig. 3 has represented the position configuration situation by three satellite gears 14 and outer star internal gear 13 train that constitutes and the wheel 15 of feeling relieved.

Fig. 4 has provided another embodiment that planet circular system constitutes and disposes.

The operation of the utility model embodiment and working process brief description are as follows:

1, at first service braking lock 8 is unclamped in assurance or inspection, and lock insures damper brake 7 surely.

2, by promoting switch, actuating motor 6, planet circular system setting in motion, inner gear 13 full speed runnings.

3, unclamp insurance damper brake 7, the service braking lock 8 that closes, driving gear 10 begin to rotate, and drive driven gear 2 motion ， And and further slow down, and the hauling rope 11 on the reel 3 constantly is wound on the reel, constantly draws mine car and reaches the lifting purpose.When putting in place, unclamp service braking lock 8, and stop.

4, when transferring car, press downing switch, make the electrical motor counter-rotating, and then the service braking lock 8 that closes, reel also reverses, and hauling rope is sent, and mine car is descending along track, sinks to mine.

When trailed mine car is about to put in place, (promptly arrive well head or shaft bottom near time) can be by the braking force between the outer wheel face (shell) that changes angular displacement service braking lock 8 and planet inner gear 13, the rotation speed change of inner gear 13 is realized, be equivalent to the motion on the reel is constantly transferred on the outer wheel face, this mechanical speed governors mode, convenient and intuitive, up to outer wheel face (being inner gear) full speed running, mine car puts in place, cuts off the electricity supply again.

5, end-of-job, motor power shuts down after cutting off, and is last, fixed insurance damper brake lock, and (this moment, the service braking lock should get loose) is in and treats mode of operation.
