Connecting part between iron tower climbing falling preventing safety rope and guide rail and using method

Abstract

The invention relates to a connecting part between an iron tower climbing falling preventing safety rope and a guide rail. The connecting part comprises a clamping base. A fixing base is arranged on the upper side of the clamping base. The upper portion of the fixing base is connected with a pulling lug in an arc-shaped structure. A connecting hole is formed in the upper portion of the pulling lug. A safety plate is hinged to the lower portion of the pulling lug. An anti-skid strip is arranged on the lower side face of the safety plate. A guide wheel is connected to the middle portion of the clamping base. A side sliding preventing plate and a pressing plate are arranged on the inner side face of the lower portion of the clamping base and are symmetrical. The outer side face of the side sliding preventing plate is provided with side sliding preventing strips distributed uniformly. The outer wall of the pressing plate is provided with uniform pressing strips. The lower portion of the pressing plate is in thread connection with a thread rod. The input end of the thread rod is connected with a speed reducer. The speed reducer is connected with the clamping base through bolts. The input end of the speed reducer is connected with a servo motor. The servo motor is connected with a single-chip microcomputer through a signal line. The output end of the single-chip microcomputer is connected with a pressure sensor through a signal line. The pressure sensor is arranged in the clamping base. The connecting part has the advantages of being reasonable in structure, convenient to use andlow in operation cost.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering equipment, and in particular relates to a connecting piece between an iron tower climbing anti-falling safety rope and a guide rail and a using method. Background technique [0002] In electric power work, overhead lines and maintenance of overhead lines are required, which requires personnel to climb the iron tower, and safety protection facilities are required, such as the tower anti-fall device. Usually the iron tower anti-fall device is I-shaped steel, which adopts the cladding guide rail. Design, the contact area with the guide rail is relatively large, and it is easy to form jams due to uneven friction or force not on the central axis when sliding. Steel balls reduce the contact area, or put copper rollers to reduce the contact area. In this way, not only the cost is high, but also the effect of reducing jamming is not very good due to the relatively large torque, resultin...

[0002] In electric power work, overhead lines and maintenance of overhead lines are required, which requires personnel to climb the iron tower, and safety protection facilities are required, such as the tower anti-fall device. Usually the iron tower anti-fall device is I-shaped steel, which adopts the cladding guide rail. Design, the contact area with the guide rail is relatively large, and it is easy to form jams due to uneven friction or force not on the central axis when sliding. Steel balls reduce the contact area, or put copper rollers to reduce the contact area. In this way, not only the cost is high, but also because the torque is relatively large, the effect of reducing jamming is not very good, resulting in inconvenient use and low efficiency
