Background

In the operation maintenance and overhaul of the power transmission line, a maintainer needs to climb onto a telegraph pole to overhaul, a foot buckle is one of common tools, and the foot buckle is an arc-shaped iron tool which is sleeved on a shoe and used for climbing the telegraph pole. The climbers mainly comprise cement pole climbers and wood pole climbers, and are divided into triangular tube climbers and circular tube climbers. The wooden pole climber is mainly suitable for ascending a height of a concrete pole or a steel pipe tower of an electric power line or a post and telecommunications line. The cement pole climber is mainly suitable for climbing poles on cement poles of electric power and post and telecommunications lines. The foot buckle is characterized in that the other side of the foot buckle is tightly buckled on a telegraph pole by the self weight of a human body under the lever action to generate larger friction force, so that people can easily climb; when the foot is lifted, the gravity borne by the foot is reduced, and the foot fastener automatically loosens. Utilizes the self-locking phenomenon of mechanics. When the line of action of the resultant of the forces acting on the object is within the angle of friction, no matter how large the force is, there is always a full counter-force in equilibrium with it, and the object remains stationary; conversely, if the line of action of the resultant of the forces is outside the angle of friction, the object may not remain balanced regardless of how small the force is.

In the power line work process, traditional climbers mainly utilize frictional force work, and after the climbers were used for a long time, there was the circumstances that frictional force descends, made it and line pole fixed insecure, from power maintenance safety regulation, need regularly detect the frictional force of climbers, made it keep reliable and stable user state to in time maintain or change unqualified climbers.

The chinese utility model with patent application number 201721382689.4 discloses a climber bearing capacity detection system, which comprises a base; the upper part of the base is provided with a first telescopic part and a second telescopic part which are vertical to the base; the first telescopic member comprises a first moving part; the second telescopic member comprises a second moving part; a fixed beam is connected between the first moving part and the second moving part; a fixed rod extends downwards from the middle part of the fixed beam, and the end of the fixed rod is provided with a pressing device with a bottom surface in a circular shape; the utility model also comprises a climber buckling device; the periphery of the base is provided with a fence. Can detect the bearing capacity that the climbers can bear to show through the display, can make this climbers of quick detection of experimenter can bear big power, and then confirm whether qualified this climbers. The device has the disadvantages that only one foot fastener can be detected at one time, and the device has a complex and heavy overall structure and is inconvenient to transport and move.
