Cable-clamping-facilitating pulley for cable penetration

Abstract

The invention discloses a cable-clamping-facilitating pulley for cable penetration, and relates to the technical field of cable penetration equipment. The pulley comprises a body and rollers which arearranged on the body. The body comprises bearing rings which are arranged at the head and the tail of the body. Each bearing ring is provided with three first through holes arranged in an annular array. A support rod is connected between the bearing rings of the head and the tail of the body. Three casters are arranged on each bearing ring. Each caster comprises a foot rod which is arranged in the first through hole along the radial direction of the bearing ring. The rollers are arranged at the outer end of the foot rod. An adjusting mechanism used for changing the outer rod length of the foot rod is connected on the inner end of the foot rod. A second linkage rod is connected between each foot rod at the head of the body and each foot rod at the tail of the vehicle body, and a cable clamping mechanism detachably connected with the body is arranged on the tail of the body. The cable clamping mechanism is separately and detachably installed on the tail of the pulley so as to greatly accelerate the speed of cable clamping and remarkably improve efficiency of the cable penetration.

Description

technical field [0001] The invention relates to the technical field of cable pipe threading equipment, in particular to a pulley for cable pipe threading that is convenient for cable clamping. Background technique [0002] Cable is a general term for items such as wires, optical cables, and cables. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, power transmission, etc. It is a common and indispensable thing in social development and daily life. In order to prevent the cables from being damaged by external factors and the regularity of the cable layout, it is usually necessary to pass the cables into the protection tube for protection. In practical applications, due to the uncertainty In the existing technology, when laying cables by manpower and threaders, there are problems such as low construction efficiency, long time consumption, and large manpower output. When the cable is threaded, the surface lay...

AI Technical Summary

Problems solved by technology

The tractor in this application can pull the cable well for pipe penetration, but the cable buckle on the tractor is integrated with the car body and cannot be disassembled and separated. In actual operation, due to the cable specification, size, quantity It is inconvenient to hold the tractor to clamp the cable, which greatly affects the efficiency of the cable through the pipe.
