Description
Technical field
The invention belongs to elevator and subtract stroke apparatus field, especially relate to and a kind of contactlessly subtract stroke apparatus.
Background technology
When elevator transfers slow train operation at express, by subtracting stroke apparatus, cut off high-speed operation, access low-speed running, impels the accurate flat bed of the upper and lower end station of elevator; When the normal throw-over of elevator is out of control, force elevator throw-over, thus avoid sinking to the bottom or rushing to summit the time, ensure elevator use safety.
At present, elevator subtracts stroke apparatus and is generally contact, throw-over switch is arranged on upper and lower two end station respectively, its the slightly delayed normal throw-over point in installation site, when elevator moves to two normal throw-over devices of end station, when lift car enters this section, the iron device that touches be contained on car contacts with the wheel that touches of throw-over switch, has run correcting to elevator; When elevator run to two end station can not normally throw-over time, the iron device that touches loaded on car contacts with the wheel that touches of throw-over switch, switch cutoff fast relay circuit makes it discharge, and elevator changes low speed into by high-speed cruising, impels the accurate flat bed of the upper and lower end station of elevator; Avoid sinking to the bottom or rushing to summit event when elevator operation exception, the end and hit top and cause the person and the generation of equipment breakdown in case elevator pauses fast.
Owing to being mechanical contact, therefore there is larger noise in the stroke apparatus that subtracts of the prior art; Because this device also needs frequent action when elevator normally runs, the reliability of this device of personnel's periodic inspection that needs repairing.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of noiseless, working stability failure-free is contactless subtracts stroke apparatus.
For solving the problems of the technologies described above, the technical solution used in the present invention is: one is contactless subtracts stroke apparatus, comprises bistable magnetic swich general assembly and the general assembly of magnetic beans;
Described bistable magnetic swich general assembly comprises electric bakelite plate, bistable magnetic swich, connection terminal and the first support; Some described bistable magnetic swich are fixed on electric bakelite plate in turn, described connection terminal is fixed on electric bakelite plate, described bistable magnetic swich is connected by wire with connection terminal, and described electric bakelite plate is fixedly connected with the first support, and described first support is fixedly connected with car;
The general assembly of described magnetic beans comprises the second support, chute, magnetic beans and pressure guide plate; Described second support comprises upper bracket, lower bracket and guide plate, and described guide plate two ends connect upper bracket and lower bracket respectively, and described upper bracket and lower bracket are parallel to each other, and not in same plane; Described chute is connected with lower carrier plate lower surface, and some described magnetic beans are fixedly connected with chute; Described pressure guide plate is connected with upper bracket, and described upper bracket is connected with guide rail by pressure guide plate.
Preferably, described chute and lower carrier plate are parallel to each other, and described chute and lower carrier plate are mutually vertical.
Preferably, the general assembly of described magnetic beans is separately fixed at upper end and the bottom of hoistway.
Preferably, described bistable magnetic swich is provided with four.
The advantage that the present invention has and good effect are: employing bistable magnetic swich coordinates with magnetic beans, and without the need to carrying out mechanical type contact, elevator work is reliable and stable, and consume energy low, noise is low, and Installation and Debugging are convenient.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As Figure 1-5, one is contactless subtracts stroke apparatus, comprises bistable magnetic swich general assembly 1 and magnetic beans general assembly 2; Described bistable magnetic swich general assembly 1 comprises electric bakelite plate 11, bistable magnetic swich 12, connection terminal 13 and the first support 14; Some described bistable magnetic swich 12 are fixed on electric bakelite plate 11 in turn, described connection terminal 13 is fixed on electric bakelite plate 11, described bistable magnetic swich 12 is connected by wire with connection terminal 13, described electric bakelite plate 11 is fixedly connected with the first support 14, and described first support 14 is fixedly connected with car; Described magnetic beans general assembly 2 comprises the second support 21, chute 22, magnetic beans 23 and pressure guide plate 24; Described second support 21 comprises upper bracket 211, lower bracket 212 and guide plate 213, and described guide plate 213 two ends connect upper bracket 211 and lower bracket 212 respectively, and described upper bracket 211 and lower bracket 212 are parallel to each other, and not in same plane; Described chute 22 is connected with lower carrier plate 212 lower surface, and described chute 22 is parallel to each other with lower carrier plate 212, and described chute 22 is mutually vertical with lower carrier plate 212, and some described magnetic beans 23 are fixedly connected with chute 22; Described pressure guide plate 24 is connected with upper bracket 211, and described upper bracket 211 is connected with guide rail by pressure guide plate 24.Described magnetic beans general assembly 2 is separately fixed at upper end and the bottom of hoistway.
