Abstract
The utility model relates to an elevator braking device. The braking device comprises an elevator control module (1), a braking disc (2) and a rotary encoder (7) connected with the braking disc (2). The braking device further comprises a first brake (3) and a second brake (8). The first brake (3) and the second brake (8) are connected with the elevator control module (1) and are used for braking the braking disc (2). The elevator control module (1) is used for selectively relieving one of the braking states of the first brake (3) and the second brake (8) when an elevator starts and detecting the braking state of the braking disc (2) through the rotary encoder (7); and if the braking disc (2) moves rotationally, an alarm is sent out. The braking disc (2) is arranged on a traction machine (9) of the elevator, ensures that the two brake complete the braking action simultaneously every time braking action is carried out, and completes the detection of one brake every time the braking is relieved, so that the practical effect of every brake is ensured, the on-line real-time monitoring of the braking system is realized, and the safety of the device is higher.
Description
Technical field
The utility model relates to elevator, relates in particular to a kind of brake device for elevator.
Background technology
Elevator brake system relates to safe key device, traditional elevator brake system consists of drg and engine installation thereof, according to traditional specification, only drg and power system thereof are enforced to quality certification to control safe reliability, operating braking effect is not made to real time on-line monitoring, therefore, if relevant device contains recessive design or defect of fabrication while causing drg braking effect disappearance, system cannot be predicted in advance, causes potential safety hazard.
With reference to figure 1, elevator control module 1 and towing machine 9 and form closed-loop drive systems for rotating the rotary encoder 7 of feedback, brake disc 2 and the first drg 3 form brake system, and this quasi-tradition structure cannot sensed in advance before misfunctioning of brake.
Summary of the invention
For solving the technical matters that misfunctioning of brake in prior art cannot perception, the utility model provides a kind of elevator control gear whether drg lost efficacy that detects.
For achieving the above object, the technical solution adopted in the utility model is: a kind of brake device for elevator, comprise elevator control module, brake disc and the rotary encoder being connected with described brake disc, it is characterized in that: also comprise the first drg, second brake, described the first drg is connected with described elevator control module with described second brake, for braking described brake disc;
Described elevator control module is removed the braking mode of one of described the first drg, described second brake for alternate selection when elevator starts, and detect described brake disc braking mode by described rotary encoder, if described brake disc rotates displacement, report to the police.
The first preferred version of the present utility model is that described brake disc is located on the towing machine of elevator.
Technical advantage of the present utility model is: when this device has guaranteed that each braking maneuver occurs, there are two cover drgs to complete braking maneuver simultaneously, when each brake off action, complete the wherein detection of a set of drg, guarantee the actual effect of each braking, realized the on-line real time monitoring to brake system.Make the safety of this device higher.
Accompanying drawing explanation
Fig. 1 is prior art brake equipment schematic diagram.
Fig. 2 is the module diagram of the present embodiment brake device for elevator.
Reference numeral is said sentence: 1-elevator control module, 2-brake disc, 3-the first drg, 4-elevator, 5-lift car, 6-counterweight, 7-rotary encoder, 8-second brake, 9-towing machine.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to figure 2, a brake device for elevator, comprises elevator control module 1, brake disc 2 and the rotary encoder 7 being connected with brake disc 2, also comprises the first drg 3, second brake 8, the first drg 3 is connected with elevator control module 1 with second brake 8, for braking brake disc 2;
Brake device for elevator has comprised two and has overlapped mutually independently brake equipment the first drg 3 and second brake 8, and the brake torque of its every cover drg all can meet the demand of elevator brake moment of torsion, and meets elevator safety standard.When elevator control module 1 provides brake command, two cover drgs complete braking maneuver simultaneously; When elevator obtains after lifting action order, first only separate the braking mode of the first drg 3, maintain the braking mode of second brake 8, now elevator control module 1 judges state of elevator by the swing offset of judgement brake disc 2, if there is displacement action to occur, represent that second brake 8 had lost efficacy, must manually overhaul, complete the one-time detection to second brake; Upper, once brake when release movement occurs, elevator control module 1 is exchange detected object, successively cycle detection automatically.
Protection scope of the present invention is not limited to the scope that embodiment explains, and all changes based on inventive concept, all belong in protection scope of the present invention.
Claims (2)
1. a brake device for elevator, comprise elevator control module, brake disc and the rotary encoder being connected with described brake disc, it is characterized in that: also comprise the first drg, second brake, described the first drg is connected with described elevator control module with described second brake, for braking described brake disc;
Described elevator control module is removed the braking mode of one of described the first drg, described second brake for start alternate selection when elevator, and detect described brake disc braking mode by described rotary encoder, if described brake disc rotates displacement, report to the police.
2. brake device for elevator according to claim 1, is characterized in that: described brake disc is located on the towing machine of elevator.
