Description
Technical field
The utility model relates to the security technology area of lift car, particularly relates to a kind of elevator anti-surpassed distance triple protection device.
Background technology
Elevator is as a kind of transport facility of uniqueness, and it must possess many-sided safety device, especially the elevator of car type.Because car drives hoist ropes control the liter of car or fall by towing machine, so if there is the situation of elevator electrical system down in elevator runs, then accurately cannot control car, after easily causing car to arrive top layer or bottom, still continue the problem travelling (rush to summit or squat at the end).
Summary of the invention
In order to solve the problem existing for background technology, the purpose of this utility model is to provide a kind of elevator anti-surpassed distance triple protection device, and it can prevent the surpassed distance be in operation because control fault causes.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of elevator anti-surpassed distance triple protection device, described fender guard is installed between car 6 and hoistway 15, described fender guard comprises the guide wheel 1 and terminal limit switch 3 that are arranged on described hoistway 15 over top, winding steel rope 2 on described guide wheel 1, described steel rope 2 one end is provided with clump weight 4, and the other end connects described car 6; The longitudinal vertical level direction of described hoistway 15 inwall is provided with guide rail 5, described guide rail 5 top be provided with successively from top to bottom limit switch touches wheel 7, upper limit position switch 8, on force speed reducing switch 9, be provided with above described car 6 with described limit switch touches wheel 7, upper limit position switch 8, on force speed reducing switch 9 to match upper switch re-pack 10; Wheel 14 is touched under being provided with down successively from top to bottom and forcing speed reducing switch 12, lower position switch 13, limit switch in described guide rail 5 bottom, be provided with below described car 6 with described under force speed reducing switch 12, lower position switch 13, limit switch under touch the lower switch that wheel 14 matches and re-pack 11.
The utility model has following beneficial effect: force speed reducing switch, limit switch, limit switch formation elevator to prevent the three pipe protection outposts of the tax office of surpassed distance in the utility model, can prevent from being in operation the surpassed distance caused because controlling fault.In the elevator that velocity ratio is higher, can establish and severally force speed reducing switch, what be respectively used to short travel and Long travel forces deceleration; When car does not have stop layers in end station and touches limit switch, cutting direction control circuit makes elevator stop running to dangerous direction immediately, and elevator still can to secure side to operation; When elevator after limit switch action still can not be out of service, then touch limit switch and cut off circuit, make driving main frame and drg dead electricity, elevator shuts down.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: guide wheel 1, steel rope 2, terminal limit switch 3, clump weight 4, guide rail 5, car 6, limit switch touch wheel 7, upper limit position switch 8, on force speed reducing switch 9, upper switch re-packs 10, lower switch re-packs 11, under force speed reducing switch 12, lower position switch 13, limit switch under touch wheel 14, hoistway 15.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail.
A kind of elevator of the utility model anti-surpassed distance triple protection device, as shown in Figure 1, described fender guard is installed between car 6 and hoistway 15, described fender guard comprises the guide wheel 1 and terminal limit switch 3 that are arranged on described hoistway 15 over top, winding steel rope 2 on described guide wheel 1, described steel rope 2 one end is provided with clump weight 4, and the other end connects described car 6; The longitudinal vertical level direction of described hoistway 15 inwall is provided with guide rail 5, described guide rail 5 top be provided with successively from top to bottom limit switch touches wheel 7, upper limit position switch 8, on force speed reducing switch 9, be provided with above described car 6 with described limit switch touches wheel 7, upper limit position switch 8, on force speed reducing switch 9 to match upper switch re-pack 10; Wheel 14 is touched under being provided with down successively from top to bottom and forcing speed reducing switch 12, lower position switch 13, limit switch in described guide rail 5 bottom, be provided with below described car 6 with described under force speed reducing switch 12, lower position switch 13, limit switch under touch the lower switch that wheel 14 matches and re-pack 11.
The utility model can prevent from being in operation and control the surpassed distance that fault causes.Force on described speed reducing switch 9, under force speed reducing switch 12 to be prevent the first of surpassed distance from closing; after being generally located at the normal throw-over switch of end station; when switch hits; described car 6 is forced to transfer low cruise to immediately; in the elevator that velocity ratio is higher; can establish and severally force speed reducing switch, what be respectively used to short travel and Long travel forces deceleration.
Described upper limit position switch 8, lower position switch 13 are that the second of anti-surpassed distance closes, when described car 6 does not have stop layers in end station and touches limit switch, cutting direction control circuit makes elevator out of service immediately, but be only now prevent from running to dangerous direction, elevator still can to secure side to operation.
Limit switch is the 3rd pipe protection of anti-surpassed distance, when elevator after limit switch action still can not be out of service, then touches limit switch and cuts off circuit, driving main frame is shut down rapidly.After ac voltage speed control elevator and the action of alternative-frequency speed-regulation elevator limit switch, driving main frame should be able to be made to shut down rapidly, power circuit or main contactor coil circuit should be cut off to single speed or double-speed elevator, limit switch action should be able to prevent elevator in the operation of both direction, and without competent personnel adjustment, elevator can not resume operation automatically.
Anti-surpassed distance protection switch be all re-pack 10 by the described upper switch be arranged on car, lower switch re-packs 11 shake-up; re-pack and must ensure enough length; switch can be pushed down in the scope of the whole surpassed distance of car; and the control circuit of switch is when will ensure that switch is held down disconnection, circuit can not be connected all the time.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, other amendments that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
