[0002] Brakes are mainly used for mechanical braking in various applications such as lifting, transportation, metallurgy, ports, and construction, which are compatible with building drives.

[0003] When the brake in the prior art is powered on, the electric hydraulic pusher is activated, the push rod rises rapidly, and the brake shoe is opened (released) by the lever action; when the power is off, the brake shoe is closed (engaged) by the lever action.

[0004] In the process of opening and closing the gate, the existing electro-hydraulic brake uses the push rod of the electro-hydraulic actuator to drive the lever to move to open or close the brake shoe. The manual release device can also realize the opening or closing operation of the conventional brake. However, when the power or network is cut off, the existing brake cannot be released or locked, so that the workpiece suspended in the air can be lowered. Therefore, the safety is insufficient.

The push rod 421 on the power output end of the pusher 42 is connected to a pin at one end of the lever 32. The UPS power supply is electrically connected to the pusher 42 (the UPS power supply is not shown in the figure. The UPS power supply does not need to be designed on or around the pusher 42. It only needs to be electrically connected to control the pusher 42). The UPS power supply starts when the power grid is cut off, and the UPS power supply supplies power to the pusher 2, driving the push rod 421 on the pusher 42 to move, thereby completing the process of driving the braking mechanism.

[0025] In this embodiment, the pusher 42 is an electric hydraulic pusher.

[0026] In this embodiment, the dynamic mechanism includes two groups of brake units, which include a brake arm and a brake shoe 61. The brake arm is connected to the middle pin of the brake shoe 61. The brake arm is also provided with a third adjustment unit, which includes an adjustment sleeve 51 and a third adjustment pin 52. The adjustment sleeve 51 is fixedly connected to the front end surface of the brake arm.

By extending the third adjustment pin 52 into the adjustment sleeve 51 at different lengths, the installation angle of the brake shoe 61 is adjusted to achieve fine-tuning of the brake shoe 61 and improve the braking accuracy.

[0027] In this embodiment, the brake arms of the two groups of brake units are respectively the first brake arm 71 and the second brake arm 72. The brake shoes 61 on the first brake arm 71 and the second brake arm 72 are arranged opposite to each other. During the up and down movement of the push rod 421, the lever 32 drives the first brake arm 71 and the second brake arm 72 to move closer to or away from each other, completing the entire action of releasing or engaging the brake.
