Description

Technical Field

[0001] The utility model relates to the technical field of steel strand traction devices, and particularly relates to an adjustable steel strand traction device. Background Art

[0002] A steel strand is a steel product composed of multiple steel wires twisted together. During the process of producing the steel strand into a bundle, it is necessary to transport the steel strand from the storage bin to the bundling device. The traction machine in the current technology presses the steel strand with upper and lower two wheels. The upper and lower two wheels are fixedly installed and cannot be easily moved, so as to rely on friction for transportation, which can reduce the labor intensity of workers. However, the steel strands to be transported are various, and different specifications result in different diameters. Therefore, the installation dimensions of the adopted traction machines are also different.

[0003] The existing traction machine must continuously reinstall to control the distance between the two traction wheels in order to achieve the traction function for steel strands of different specifications, which increases the installation intensity and transportation cost, brings trouble to the transportation process, and makes the transportation efficiency relatively low.

[0004] In order to solve the problem of inconvenient position adjustment between the above-mentioned traction wheels, after retrieval, the utility model patent with the publication number of CN221140615U in the prior art discloses a steel strand traction device, which includes an operating table. A first chute is opened at the top of the operating table. A slider is movably embedded in the inner surface of the first chute. A threaded rod is threadedly connected to the inner surface of the first chute. One side of the outer wall of the threaded rod is fixedly connected with a hand crank. A first installation groove is opened on one side of the outer wall of the operating table.

[0005] During the use of the above-mentioned prior art, it is necessary for the staff to place the steel strand between the two traction rollers and rotate the hand crank to fix the steel strand tightly. At this time, starting the first motor can complete the automatic traction of the steel strand. When traction is performed on steel strands of different specifications, it is necessary to continuously rotate the hand crank to adjust the distance between the traction rollers, and the adjustment efficiency is relatively low.
