Embodiment Construction
[0080] Such as Figure 1-27 As shown, the self-locking brake control system of the present invention is slidably connected with the guide rail 100 and the brake control system of the present invention is fixedly installed on the moving object. The advantage of the brake control system adopted in the present invention is that it does not use conventional weightlessness Trigger, but use the way of sensing the moving speed of the moving object to trigger. When the moving speed of the moving object in the vertical / horizontal direction is too fast, the trigger braking control system will start to work, thereby reducing the moving speed of the moving object Until zero, to protect the safety of moving objects.
[0081] Such as Figure 1-27 As shown, the elevator braking system based on hydraulic cylinder triggering buffer braking includes a connecting device 200, a braking device 400, and a speed sensing device 600. The connecting device 200 is slidably connected to the guide rail 1...

The invention provides an elevator stop system for triggering buffer type braking for cylinders on the basis of hydraulic pressure. The system comprises a connection device, a braking device and a speed sensing device, wherein the connection device is connected with a guiderail in a sliding manner; a power reception end of the braking device is connected with the connection device; a power outputend of the braking device is connected with the speed sensing device; the connection device is used for transferring a motion speed of a moving object to the speed sensing device through the braking device; motion states of the speed sensing device are divided into an non-triggered state and a triggered state; when the moving object moves normally, the speed sensing device is located in the non-triggered state and the braking device does not influence the movement of the moving object; when the motion speed of the moving object is too high, the speed sensing device is located in the triggeredstate and the braking device stops the moving object; and a buffer mechanism is arranged between a power output end of the connection device and the power reception end of the braking device so that the connection device and the braking device can be connected for transmission.
Description
technical field [0001] The invention relates to a mechanical fall arrester, in particular to a fall arrester triggered by speed. Background technique [0002] The anti-fall device is mainly used in the safety protection of elevators and elevators to avoid damage to personnel and equipment caused by the rapid decline of elevators and elevators. [0003] The original design intention of the existing fall arrester is to consider locking and braking at the fastest speed to reduce the braking distance and avoid personal injury, and this design concept is also adopted in the actual elevator protection system. However, the actual use process Among the passengers, there are many elderly people. When the elevator slides rapidly to stop and switches, it will cause the people in the weightless state to land hard, which will cause the passengers to collide with the elevator car floor, causing secondary damage to the internal passengers. Injuries, especially the elderly, greatly increas...
