Abstract

The utility model discloses a drive electromotive walking device. The drive electromotive walking device comprises a drive reducing motor, a protective barrel, a magnetic wheel set, a dish-shaped gearand a gear shaft, and realizes the forward walking function. When the drive reducing motor is damaged, the electromotive walking device pulls and drives a wire rope by an external force, a compression pressure spring of a ring-shaped retaining ring is pressed by a limiting stop hook on the movable shaft, and the gear shaft is separated from the dish-shaped gear, so that rotation torque of the dish-shaped gear during rotation is relieved, the entire device is extracted from the pipeline through drawing the wire rope under the action of the external force, and the pipeline is prevented from being blocked.

Description

De-driving type electrical walking device

Technical field:

The utility model is a kind ofly can and drive the device that can extract under external force when reducing motor breaks down at pipe walking.

Background technique:

The current power walking device that drives reducing motor that adopts in pipeline has many, as caterpillar, spiral is wheeled, contracting, it is wheeled to stretch support, road wheel in these modes all by axle with drive the reducing motor motion that links to each other, in case driving reducing motor has damaged owing to abominable operating mode in pipeline, moment of rotation during its fault is very big, cause driving wheel not rotate, adopt the wheel of these walking manner devices with inner-walls of duct very big friction to be arranged again, so device is outwards moved under external force, cause line clogging, even causing whole pipe to scrap, its economic loss is huge.

The model utility content:

The purpose of this utility model provides a kind of de-driving type electrical walking device, can in pipeline, advance, can also be when driving the reducing motor damage, withdraw from pipeline under external force, can not be blocked in the pipeline, it is by driving reducing motor, casing, the magnet-wheel group constitutes, in the casing neutral position driving reducing motor is housed, the guide pin bushing that on the motor shaft front end sleeve, has tooth axle and annular retaining ring, and stage clip is housed in guide pin bushing inside, by the slotted hole on the guide pin bushing jack-post is fixed on the motor shaft, after front axle is packed in the casing by the shaft sealing cover at casing two ends, load onto the interior retaining of axle of left end, refill retaining in dish-shaped gear wheel and the right-hand member axle, and with about in two axles retaining and dish-shaped gear wheel and front axle fix, and make the engagement of dish-shaped gear wheel and tooth axle, pass through wheel bumping post and fastening nut 1 at the front axle two ends of casing outside with interior magnet-wheel, the magnet-wheel group that rubber wheel and outer magnet-wheel are formed fixes, on the extension spring fixing column before extension spring one end is fixed on the sealing cover, the other end connects together by extension spring ring and drive solution wire rope and shifting axle one end, the shifting axle the other end is connected with the drive solution wire rope after passing two shifting axle guide pin bushings, the drive solution wire rope is connected with draw ring by the locked coil wire rope hole, shifting axle front end in the middle of two shifting axle guide pin bushings is fixed with spacing stop hook, be fixed with the stop hook post in the shifting axle neutral position, block tongue is fixed on the casing by axis and card base, card spring sheet one end is fixed on the casing, the other end is fixed on the block tongue, the cable that drives reducing motor is guided to sealing cover outside, back by the cable seal hole, assurance links to each other with the back sealing cover with towing pad by haulage cable, back sealing cover is fixed together with retaining screw 1 and casing, by rear axle two magnet-wheel groups is housed in both sides, casing back.

The technique effect that technological scheme reached that the utility model provides is achieved in that when driving reducing motor in energising, motor shaft begins rotation, the jack-post drive guide pin bushing and the tooth axle that are fixed in slotted hole on the motor shaft rotate together, make the also together rotation of dish-shaped gear wheel after tooth axle and the engagement of dish-shaped gear wheel, the dish gear wheel drives by interior magnet-wheel by front axle, the both sides magnet-wheel group that rubber wheel and outer magnet-wheel are formed is rotated, also driving two the magnet-wheel groups in casing back simultaneously rotates, thereby whole device can be moved, the controlling and driving reducing motor just, counter-rotating can realize that this device moves forward and backward.

Damage in the pipeline under the mal-condition when driving reducing motor, promptly driving reducing motor has not changeed, at this moment, the magnet-wheel group is rotated very difficulty, even can not rotate, magnet-wheel group and tube wall have been set up very big friction in addition, the two does not separate with tooth axle and dish-shaped gear wheel, whole device will be blocked in the pipeline, when this phenomenon of the failure occurs, can spur the elastic force that draw ring overcomes extension spring for this reason, move after making the drive solution wire rope with external force, thereby move after making shifting axle, shifting axle moves after driving spacing stop hook, makes spacing stop hook run into annular retaining ring, and its stage clip elastic force that overcomes in the guide pin bushing is moved after together, the stop hook post moved after also block tongue was lifted this moment, after the stop hook post was crossed block tongue, block tongue bullet under the effect of card spring sheet blocked the stop hook post, and the two separates tooth axle and dish-shaped gear wheel, jack-post relatively moves in slotted hole, does not influence above-mentioned moving.Because the driven magnet-wheel group of front end has been removed the moment of rotation of speed reducer, will rotate flexibly, just can this device be extracted pipeline thereby pulling is held, solve fully under the situation that drives the reducing motor damage, not make this device blocking pipe by haulage cable.

Technological scheme design disclosed in the utility model is ingenious, simple in structure, easily manufactured, practicability is extremely strong, application is extensive, is a good technological scheme with novelty, creativeness and practicability.
