Embodiment 1
[0060] A kind of vertical ladder climbing method, comprises the following steps:
[0061] a. Use the sling 1 to connect with the vertical ladder climbers;
[0062] The suspension rope 1 is wound on a reel, and the reel is rotatably installed on the horizontal support bar at the top of the vertical ladder. A braking signal transmission structure for obtaining the reel speed and a braking structure for providing braking force when the vertical ladder climber who is buckled with the suspension rope 1 falls;
[0063] b. When the vertical ladder climber climbs up, start the drive motor to lift the sling 1 and assist the vertical ladder climber to climb up; when the vertical ladder climber climbs down, the drive motor is turned off;
[0064] In the process of climbing up and down, the braking signal transmission structure acquires the rotating speed of the reel in real time, and uses the rotating speed to judge whether the vertical ladder climber has fallen; when the vertical ladde...

[0103] The brake structure includes a brake, a hub and a solenoid valve, wherein the brake is a disc brake; the hub is fixed coaxially on the rotating shaft at the end of the reel away from the drive motor, and the brake disc of the brake It is fixedly connected with the hub, and the electromagnetic valve is arranged in the brake fluid pipeline on the brake, and the control end of the electromagnetic valve is electrically connected with the output end of the transmission cable.
[0104] The above braking structure can utilize the advantages of the disc brake, such as fast heat dissipation, light weight, simple structure, convenient adjustment and stable braking effect, to better prevent climbing and falling and ensure climbing safety.
[0105] During implementation, the brake can also be selected as a drum brake, and when the brake is a drum brake, the required braking purpose of the present invention can also be achieved.
Embodiment 3
[0107] The braking structure includes a rotary damper; the rotary shaft of the rotary damper is rotatably connected with the rotary shaft of the reel.
[0108] The rotary damper can change its own torque according to the change of the rotation speed of the reel. The law of change is: the faster the reel speed, the greater the torque. The slower the drum speed, the lower the torque.
[0109] Statistics show that the normal climbing process of climbers tends to be at a constant speed (about 1 meter per second). In this way, when the above-mentioned vertical ladder climbing anti-fall booster device is in use, the torque of the rotary damper is a constant value. , will not have a major impact on the climbing process. But once the climber falls, the speed of the reel will be accelerated at this time, and the above-mentioned rotary damper will increase the torque with the increase of the reel speed, slow down the reel speed, thereby slowing down the falling speed of the falling pe...
