A trolley suitable for cable elbow laying

Abstract

The invention discloses a pulley suitable for laying cable bent pipes, and relates to the technical field of cable pipe penetrating equipment. The pulley comprises a pulley body and rollers arranged on the pulley body, wherein the pulley body comprises bearing rings arranged at the head part and the tail part of the pulley body; three first through holes which are arranged in an annular array areformed on the bearing rings; steering levers are connected between the bearing rings of the head part and the tail part of the pulley body, each bearing ring is provided with three foot wheels, each foot wheel comprises a foot rod penetrating the first through holes in the radial direction of the bearing rings, the rollers are arranged at the outer ends of the foot rods, and the inner ends of thefoot rods are connected with a regulation mechanism configured to change the rod lengths of the outer portions of the foot rods; and the tail portion of the pulley body is provided with a cable clamping device detachably connected with the pulley body. The pulley can be suitable for penetrating pipes with different pipe diameters, can also deal with bent parts in the penetrating pipes, achieves laying of cable bent pipes, and greatly improves the adaptability and practicability of the cable traction pulley.

Description

technical field [0001] The invention relates to the technical field of cable pipe passing equipment, in particular to a trolley suitable for laying cable elbows. 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 layer will be worn, and the work o...

Problems solved by technology

The tractor in this application can pull cables well for threading pipes, but it is only suitable for the pipe threading operation of circular straight pipe cables. Since the support arm is fixed and cannot be adjusted, the traction block in this application is both It cannot be adjusted according to different pipe diameters in practice, nor can it be applied to curved pipes (stuck), it cannot be pulled out, and the practicability is not high
