Abstract
The invention discloses a rope protector for an elevator tractor. The rope protector for the elevator tractor is characterized by comprising a plurality of electromagnetic locks (4) arranged on elevator lead rails (2) in a sliding manner; the electromagnetic locks (4) are fixedly connected with a lift car (8) through wire ropes (6); the lift car (8) is provided with a master controller (10); a tension sensor (11) is arranged on a hauling rope (12); the tension sensor (11) is electrically connected with the master controller (10); and the master controller (10) is also electrically connected with the electromagnetic locks (4). The rope protector for the elevator tractor, disclosed by the invention, is simple in structure and stable in performance.
Description
Technical field
The present invention relates to a kind of elevator traction machine, relate in particular to a kind of elevator traction machine with the disconnected fender guard of rope.
Background technology
The elevator of elevator, especially vertical lift is to rely on the pulling force of many hauling ropes to do the vertical takeoff and landing (VTOL) operation aloft, in case hauling rope ruptures in operational process; Might cause casualties, consequence such as device damage, all can be furnished with velocity limiter on the general elevator, when the descending speed of car surpasses certain value; Velocity limiter can drive the safety tongs action; Car is clamped on the guide rail,, but still has unsettled defective of performance and problem though this kind mode can play the certain protection effect.
The Chinese patent Granted publication number is CN2897955Y; Granted publication day is that the utility model patent on May 9th, 2007 discloses a kind of jacking system hoist ropes rope break detection device; Comprise that switch bracket, detector switch, switch re-pack and the fag end device of hoist ropes; Switch bracket is fixed on the rope hitch plate of fag end device, and switch re-packs the rope head spring that is fixed on the fag end device away from an end of rope hitch plate, and detector switch is fixed on the switch bracket.Though this utility model can detect the disconnected rope situation of jacking system hoist ropes timely, its in use need be on every hoist ropes installation and measuring devices all, so not only wasting space also can disturb each other, to such an extent as to less stable.
Summary of the invention
Technical matters to be solved by this invention provides a kind of simple in structure, and the elevator traction machine of stable performance is with the disconnected fender guard of rope.
For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of elevator traction machine comprises a plurality of electromagnetic locks that slidably are installed on the cage guide with the disconnected fender guard of rope, and said electromagnetic lock is captiveed joint with car through steel rope; On the said car master controller is installed; On the said hauling rope pulling force sensor is installed, said pulling force sensor is electrically connected with said master controller, and said master controller also is electrically connected with said electromagnetic lock.
Said electromagnetic lock has two clamping faces in opposite directions, and said clamping face contacts with said cage guide.
Said clamping face is provided with rubber layer.
Buzzer phone also is installed on the said car, and said buzzer phone is electrically connected with said master controller.
Compared with prior art, beneficial effect of the present invention is:
Because elevator traction machine of the present invention is equipped with slidably electromagnetic lock with the rope fender guard that breaks on cage guide, this electromagnetic lock is electrically connected with master controller on the car, and also is electrically connected with pulling force sensor on the master controller; When hauling rope ruptured, the pulling force on the pulling force sensor can reduce rapidly, and master controller begins to switch on to electromagnetic lock after receiving the rapid information that reduces of pulling force; Electromagnetic lock is locked on the cage guide; Thereby prevent car to fall, this process is simple, and effectively; Therefore the present invention is simple in structure, stable performance.
Description of drawings
Specify the present invention below in conjunction with accompanying drawing and embodiment:
Fig. 1 is a structural representation of the present invention.
Among the figure: cage guide 2, electromagnetic lock 4, car 8, master controller 10, pulling force sensor 11, hauling rope 12.
The specific embodiment
As shown in Figure 1, a kind of elevator traction machine of the present invention mainly comprises electromagnetic lock 4, master controller 10 and pulling force sensor 11 with the disconnected fender guard of rope; Wherein electromagnetic lock 4 and pulling force sensor 11 respectively be installed in car 8 on master controller 10 be electrically connected; And electromagnetic lock 4 slidably is installed on the cage guide 2, and pulling force sensor 11 is installed on the hauling rope 12, adopts the braking principle of said structure to be: when hauling rope 12 fractures; Pulling force on the pulling force sensor 11 can reduce rapidly; Master controller 10 begins electromagnetic lock 4 to be locked on the cage guide 2, thereby to prevent car 8 to fall to electromagnetic lock 4 energisings after receiving the rapid information that reduces of pulling force.
In actual the use: electromagnetic lock 4 has two clamping faces in opposite directions, and this clamping face contacts with cage guide 2, and clamping face is provided with rubber layer, and the buzzer phone 12 of warning function also is installed on the car 8, and this buzzer phone 12 is electrically connected with master controller 10.
In sum, the present invention is simple in structure, stable performance.
The above is merely preferred embodiments of the present invention; Protection scope of the present invention is not exceeded with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
