Problems solved by technology
[0003] When the floor of the building where the elevator is located is high and the vertical height difference is large, the contact surface between the brake and the elevator track is small due to the single braking measure, which is not conducive to better provide a strong frictional blocking effect, and the existing The brake using the lever principle only uses a single lever to pry the action, so that the short moment arm cannot provide a strong lever drive. When disassembling and overhauling multiple brakes, only the bolt fastening method is used to make the bolts fasten the connected plate. The side end is tilted, which affects the stability of the device, and furthermore, it may not run stably

Embodiment Construction
[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0024] Such as Figure 1-Figure 6 As shown, an elevator brake according to the present invention includes a guide rail 1 and a car 2. The top of the guide rail 1 is sequentially provided with a first brake 3 and a second brake 4 from top to bottom. The first brake 3 The two sides of the bottom are fixedly connected with the top of the car 2 through the legs 31, and the two sides of the legs 31 are fixedly connected with the top of the car 2 through the connector 5, and the legs 31 on both sides of the first brake 3 are respectively located at the second On both sides of the brake 4, the legs 31 are located at the side edges of the top of the car 2.
[0025] Specifically, the first brake 3 includes a first clamping plate 32, and the first clamping...

The present invention relates to the field of heavy industrial machinery, specifically an elevator brake, including a guide rail and a car. The top of the guide rail is provided with a first brake and a second brake in turn from top to bottom. The top of the car is fixedly connected, the two sides of the support feet are fixedly connected with the top of the car through connectors, and the support feet on both sides of the first brake are respectively located on both sides of the second brake. By setting the first brake and combining with the second brake, it is convenient to provide double braking effect in the vertical direction of the slide rail, which is beneficial to better provide a strong friction blocking effect, and further improves the braking effect of the device, which is convenient for the floor where the elevator is located. Higher, and when the running vertical height difference is large, high-efficiency braking capability is provided. By setting the second splint, the second splint includes the first structural plate, the second structural plate and the third structural plate triple leverage offset plate, Facilitates powerful leverage actuation with long moment arms.
Description
technical field [0001] The invention relates to the field of heavy industrial machinery, in particular to an elevator brake. Background technique [0002] The elevator brake is an important safety device of the elevator. Its safety and reliability are one of the important factors to ensure the safe operation of the elevator. The two-way thrust elevator brake generates two-way electromagnetic thrust when it is powered on, so that the brake structure is separated from the rotating part of the motor. When the force disappears, under the action of the pressure of the external brake spring, a friction brake for power-off braking is formed. It is mainly matched with the driving motor on the escalator traction machine to form an electromagnetic braking three-phase asynchronous motor for escalators, which is widely used in It can realize stable parking, fast starting and safe braking when the power is cut off, but the existing elevator brakes still have the following problems in use...
