Problems solved by technology

But such climbing method still has the following deficiencies: the counterweight is suspended in the air and is easily swayed by the wind force at high altitude, which not only causes the pulling force of the safety rope to change, but also the swinging counterweight is easy to transfer and climb. The attention of climbers affects the safety of climbing

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...

Embodiment 2

[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...

Abstract

The invention discloses a method for climbing a vertical ladder. The method comprises the following steps that a, a lifting rope is buckled with a vertical ladder climbing person, wherein the lifting rope is wound around a winding drum, the winding drum is rotationally mounted on a transverse supporting rod at the top of the vertical ladder and is in driving connection with a driving motor, and a rotary shaft of the winding drum is rotationally connected with a brake signal transmitting structure and a brake structure; and b, when the vertical ladder climbing person climbs upwards, the driving motor lifts the lifting rope and assists the vertical ladder climbing person in climbing upwards, the driving motor is stopped when the vertical ladder climbing person climbs down, the brake signal transmitting structure acquires the rotating speed of the winding drum in real time, whether the vertical ladder climbing person falls off or not is judged through the rotating speed, and the brake signal transmitting structure triggers the brake structure to stop the winding drum from rotating to prevent falling when the vertical ladder climbing person falls off. According to the method for climbing the vertical ladder, more labor can be saved when the person climbs the vertical ladder, falling prevention can be achieved better, and the safety of the safety climbing person is ensured.

Description

technical field [0001] The invention belongs to the field of climbing methods for high-altitude vertical ladders, and in particular relates to a climbing method for vertical ladders. Background technique [0002] Tower cranes are the most commonly used lifting equipment on construction sites. Before operating the tower crane, climbers are required to climb to the operating room on the top of the tower crane through a vertical ladder. However, tower cranes are usually tens or even hundreds of meters high, making tower crane operation not only a high-altitude operation with high risks, but also climbing vertical ladders is a great test for the physical strength of climbers. [0003] In order to ensure the safety of the tower crane climbers and to climb the vertical ladder more easily, the existing vertical ladder climbing method adopts the patent whose notification number is CN203946820U, which discloses "a kind of construction tower crane climbing aid safety device", which i...
