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] like 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 pl...

The invention relates to the field of heavy industrial machinery, in particular to an elevator brake comprising a guide rail and a car. A first brake body and a second brake body are arranged at the top of the guide rail sequentially from top to bottom. The two sides of the bottom of the first brake body are fixedly connected with the top of the car through support legs. The two sides of the support legs are fixedly connected with the top of the car through connectors. The support legs on the two sides of the first brake body are located on the two sides of the second brake body correspondingly. The first brake body is arranged to be combined with the second brake body, thus double braking effects can be provided conveniently in the vertical direction of a sliding rail, a strong friction prevention effect can be provided better, the braking effect of the elevator brake is further improved, and efficient braking capacity can be provided conveniently when a building where an elevator islocated has high floors and the operation vertical height fall is large. A second clamping plate is arranged and comprises a first structural plate, a second structural plate and a third structural plate which achieve three lever effects on offset plates, and a high lever driving effect is provided conveniently under the action of a long force arm.
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...
