Variable frequency steel strand cable penetrating machine

Abstract

The invention relates to a variable frequency steel strand cable penetrating machine. The machine comprises a machine shell, wherein a steel strand inlet pipe and a steel strand outlet pipe are arranged on two side plates of the machine shell; a driving mechanism, a clamping mechanism and an adjusting screw rod are arranged in the machine shell; the driving mechanism comprises a reduction gear set and a carrier gear; the clamping mechanism comprises two upper occupied plates and two lower occupied plates which are symmetrically arranged; movable connection plates are correspondingly arranged at the two sides of the upper and lower occupied plates; upper pressure gears are arranged on the upper occupied plates; lower pressure gears are arranged on the lower occupied plates; the upper pressure gears are meshed with the lower pressure gears; the reduction gear set and the carrier gear are simultaneously meshed with the lower pressure gears; semicircular slots are arranged in the middle of the outer edges of the teeth of the upper and lower pressure gears; one end of each of the lower occupied plates extends upwards to form a support plate of the adjusting screw rod; support shafts are arranged between the support plates; threaded holes are arranged in the middle of the support shafts; the adjusting screw rod penetrates through the threaded holes; and the end of the adjusting screw rod is movably connected with a locking pendulum shaft. The machine has the following beneficial effects: the machine can succeed in cable releasing and cable penetrating once, can proceed or step back freely, can accurately control the length of the steel strands conveyed into prestressed ducts and can solve the problem of long-distance cable penetrating.

Description

[0001] Technical field [0002] The invention relates to a steel strand threading machine, which is mainly used for threading prestressed steel strands in viaduct and bridge construction. Background technique [0003] In the prestressing construction, the threading of the prestressed steel strands is usually done by hand, and the steel strands with a length of more than 100 meters need to be opened for assistance, which is time-consuming, tiring, and inefficient; After the stranded wire is blanked, it is placed neatly, bundled and welded or headed, and the rope is threaded by means of steel wire rope and hoist traction. The process is cumbersome and the labor intensity is extremely high. Compared with the prestressed pipeline, it is difficult to accurately control the length of the steel strand, resulting in a shorter or longer working length at the tension end. Contents of the invention [0004] Aiming at the problems existing in the above-mentioned prior art, the presen...
