Description

A method of using a stilt-type climber

technical field

The invention relates to the field of climbing mechanisms, in particular to a method for using a stilt type climbing device.

Background technique

In life and production, it is often necessary to pick up objects from high places, such as picking water and electricity installations, house decoration, cleaning walls, doors and windows, picking fruits, and placing goods on shelves, etc. Usually we use ladders and lifting platforms as tools to help people reach high places.

When using traditional ladders, it is often necessary to choose a long ladder or a short ladder according to the height of the operating point. In the case of unconditional selection, it often occurs that working in a short place requires a long ladder. The long ladder is not only cumbersome, but the too long ladder bar hinders the user. work and safety. The ladder is too short to reach the working surface, and the homework cannot be completed. During the operation, it is required to change the height from time to time, and people have to climb up and down. If you want to change your working position forward, backward, left, or right, you have to climb down from the ladder, carry your hands on your shoulders to move the ladder, and then climb up again to continue working. Cause unnecessary consumption of user's physical strength, delay working hours, and reduce operating efficiency. The movement of ladders and lifting platforms is difficult, and ladders or lifting platforms with mobile functions need to rely on the external force of other personnel or driving mechanisms to complete the movement.

Stilts are professionals whose legs are respectively fixed with a long rod, which is used as an extension of the legs. Professionals can use stilts to walk. We found that stilts are a kind of mobile that does not require external tools. Compared with ladders, stilts have lower environmental requirements. , but the stilts need long-term training before they can be used. Higher upper and lower stilts can be assisted by other personnel or stand on a high place to get on and off the stilts.

Please refer to Fig. 1, the Chinese utility model patent of notification number CN201981993U discloses a kind of stilt-type adjustable lifting step ladder, which is composed of two ladder bars which are not connected to each other.

The base 100 is located at the bottom of the scissor lift table, and there are four mounting holes 101 on it to facilitate connection with the bottom surface or other equipment. The lifting mechanism 200 is composed of two identical sets of X-shaped lifting mechanism components arranged on both sides of the base 100, which are identical and parallel to each other. Auxiliary connecting rod 201 is formed, and adjacent two layers of lifting mechanism parts are hinged together by the hinge mechanism that is arranged on connecting rod 201 two ends, and one end of a connecting rod 201 in the lowermost lifting mechanism component is hinged with base 100. The lifting drive mechanism 300 is arranged on the base, between two sets of multi-layered lifting mechanism components.
