Abstract
A retraction-releasing winch for tramcar-driving protection comprises an explosion-proof motor, a reducer and a steel wire rope retraction-releasing rotary drum, the side surface of the steel wire rope retraction-releasing rotary drum is provided with a transmission shaft in a coaxial mode, the middle section of the transmission shaft is provided with a moment-measuring thread section, a square nut is sleeved outside the moment-measuring thread section, a moment-measuring platform matched with the square nut is arranged under the square nut, the transmission shaft at two sides of the moment-measuring thread section is provided with overtravel protection grooves, and rope-winding prevention protection plates are arranged under the steel wire rope retraction-releasing rotary drum. The anti-explosion motor drives the positive and negative rotation of the rotary drum through the reducer, the travel of the square nut is measured through two sensors arranged on the moment-measuring platform, the length of a steel wire rope retracted and released by the steel wire rope retraction-releasing rotary drum is limited, and the height of a tramcar guardrail is controlled and lifted. In the operation process, once an eclectic control mechanism fails to work, the square nut and the transmission shaft can be effectively separated, and therefore the motor and the reducer are protected from being damaged.
Description
Technical field
The utility model relates to a kind of mine working safety protection technique, and particularly a kind of derail avoidance is used releasing winch.
Background technology
In the slope rail transport, promote material along the track of laying in the inclined shaft by winch traction mine car.Promoting and transferring in the process of material, for various reasons, the mine car that may produce lifting breaks away from traction control.Mine car out of control rapidly glides along track, breaks the pit shaft facility, and causes great life to threaten to following yardman.Therefore, derail avoidance is a very important safety measure in mine.
Drive cylinder by fire proof motor through reductor and carry out rotating, drive arrester through hoisting cable and promote, be caught.Conventional winch is in course of action, in case when electrical control mechanism was malfunctioning, the motor get out of hand damaged motor and speed reducer easily, influences ordinary production.
Summary of the invention
The technical matters that the utility model will solve is the deficiency to prior art, has proposed the not impaired derail avoidance of a kind of effective protection motor and speed reducer and has used releasing winch.
The technical matters that the utility model will solve realizes through following technical scheme; A kind of derail avoidance is used releasing winch; Comprise fire proof motor, reductor and steel rope folding and unfolding cylinder; Be characterized in: the coaxial transmission shaft that is provided with in the side of steel rope folding and unfolding cylinder, be set to survey the square thread segment in the stage casing of transmission shaft, survey on the square thread segment and be set with square nut; Be provided with the survey square platform that cooperates with square nut in the bottom of square nut, on the both sides transmission shaft of surveying the square thread segment, be provided with the surpassed distance protective trough.
The technical matters that the utility model will solve can also further realized, below steel rope folding and unfolding cylinder, is provided with anti-rope woolding backplate through following technical scheme.
The utility model compared with prior art drives cylinder by fire proof motor through reductor and carries out rotating, through being located at the stroke of surveying two sensor measurement square nuts on the square platform; Limit steel rope folding and unfolding cylinder folding and unfolding length of steel wire rope; Control promotes the height of arrester, in course of action, in case when electrical control mechanism is malfunctioning; Square nut can be realized effectively separating with transmission shaft, effectively protects motor and speed reducer not to be damaged.
Description of drawings
Fig. 1 is the structure diagram of the utility model.
The specific embodiment
A kind of derail avoidance is used releasing winch; Comprise fire proof motor 6, reductor 5 and steel rope folding and unfolding cylinder 4; The coaxial transmission shaft 2 that is provided with is set to survey the square thread segment in the stage casing of transmission shaft 2 in the side of steel rope folding and unfolding cylinder 4, surveys on the square thread segment and is set with square nut 3; Be provided with the survey square platform 1 that cooperates with square nut in the bottom of square nut 3, on the both sides transmission shaft of surveying the square thread segment, be provided with surpassed distance protective trough 7.Surpassed distance protective trough 7 is the optical axis section on the both sides transmission shaft of surveying the square thread segment.Drive steel rope folding and unfolding cylinder 4 by fire proof motor 6 through reductor 5 and carry out rotating, drive arrester through hoisting cable and promote, be caught.
In course of action, in case when electrical control mechanism was malfunctioning, square nut was behind surpassed distance protective trough 7; Can realize effectively separating with transmission shaft, effectively protect motor and speed reducer not to be damaged, recover easily; Only need electric motor starting is pushed down square nut with instrument, can its recovery be put in place.
Below steel rope folding and unfolding cylinder, be provided with two anti-rope woolding backplates.During no backplate, in the working process of winch, when steel rope is loosening; Be easy to wire rope roll beyond cylinder, form fast knot, thereby influence normal operation; And behind two backplates of processing below the cylinder, effectively in the cylinder with the steel rope protection that links usefulness, though the process of transferring in steel rope loosening; Also can act freely, the rope woolding phenomenon can not take place.
Claims (2)
1. a derail avoidance is used releasing winch; Comprise fire proof motor, reductor and steel rope folding and unfolding cylinder; It is characterized in that: the coaxial transmission shaft that is provided with in the side of steel rope folding and unfolding cylinder, be set to survey the square thread segment in the stage casing of transmission shaft, survey on the square thread segment and be set with square nut; Be provided with the survey square platform that cooperates with square nut in the bottom of square nut, on the both sides transmission shaft of surveying the square thread segment, be provided with the surpassed distance protective trough.
2. derail avoidance according to claim 1 is used releasing winch, it is characterized in that: below steel rope folding and unfolding cylinder, be provided with anti-rope woolding backplate.
