Unwinding device and unwinding method for subway water supply and drainage fire-fighting pipeline

Abstract

The invention discloses an unwinding device and unwinding method for a subway water supply and drainage fire-fighting pipeline, belongs to the technical field of fire-fighting pipeline winding, and solves the problems that a fire-fighting pipeline is wound disorderly, the pipeline is continuously stacked at a certain position, and pipeline winding is not facilitated. The unwinding device comprises a wind-up roll, a supporting frame, a fixing plate, a winding driving mechanism, a guiding driving mechanism and a guiding mechanism, wherein central rotating shafts are arranged at the two ends of the wind-up roll, the two ends of the central rotating shafts are fixed to the upper ends of supporting frames, and a fixing plate is further fixed to the bottom end of the supporting frame; the winding driving mechanism is arranged between one end of the wind-up roll and the corresponding position of the fixing plate and drives the wind-up roll to rotate; the guiding driving mechanism is arranged at the position, close to the fixing plate, of one side of the wind-up roll, and the placement direction of the guiding driving mechanism is the same as that of the wind-up roll; and the guiding mechanism for a pipeline to penetrate through is arranged on the guiding driving mechanism, and a clamping ring is further arranged at one end of the surface of the wind-up roll. By means of the device and the method, more orderly winding of pipelines is achieved.

Description

technical field [0001] The application relates to the technical field of fire-fighting pipeline rewinding, in particular to an unwinding device and unwinding method for subway water supply and drainage fire-fighting pipelines. Background technique [0002] Fire-fighting pipeline refers to the pipeline materials used for fire-fighting, connecting fire-fighting equipment and equipment, and transporting fire-fighting water, gas or other media. Due to special needs, the thickness and material of fire-fighting pipelines have special requirements, and spray red paint to transport fire-fighting use water. [0003] An easy-to-move subway water supply and drainage fire-fighting pipeline unwinding device disclosed in the Chinese patent application publication CN201920074459.4. and fixed by adjusting bolts, it is convenient to adjust the first assembly plate and the second assembly plate to a suitable angle, and can reasonably accommodate fire-fighting pipelines of different thickness...

AI Technical Summary

Problems solved by technology

[0005] The embodiment of the present application provides an unwinding device and unwinding method for the subway water supply and drainage fire protection pipeline, which solves the problem that the unwinding of the pipeline in the prior art is relatively disordered due to the absence of a guide mechanism during unwinding, and it is easy to cause the pipeline to be unwound at a certain point. Continuous accumulation in one position is not conducive to the winding of the pipeline, and a more orderly winding of the pipeline is realized
