Description

Technical Field

[0001] The invention belongs to the technical field of cableway winch equipment, and in particular relates to a hydrological cableway flow measuring winch device. Background Art

[0002] Hydrographic cableways are used to obtain hydrographic data more accurately by setting up tower structures on both sides of the river and high-strength steel wire ropes between the tower structures as load-bearing cables. The load-bearing cables are used to bear the weight of lead fish (heavy objects used to carry measuring instruments), cranes (devices that can move along the load-bearing cables and connect other components) and auxiliary measuring equipment, ensuring that they can be safely and stably suspended above the river for flow measurement operations.

[0003] In the prior art, since the height of the tower structure is fixed, the position of the load-bearing cable is also fixed. The corresponding trolley always moves back and forth in the same plane to drive the lead fish in the water flow to measure the hydrological data. The lead fish is connected to the trolley through a steel wire rope. Therefore, during measurement, due to the influence of the water flow, the lead fish cannot always keep in the same direction as the water flow, which will affect the measurement data; in addition, the water depth of the river is constantly changing, so the steel wire rope connecting the lead fish and the trolley also needs to adjust the length according to the water conditions, which not only affects the work efficiency, but also increases the measurement data deviation as the length of the steel wire rope changes. Summary of the invention

[0004] The purpose of the present invention is to propose a hydrographic cableway flow measuring winch device to solve the problem in the prior art that the load-bearing rope of the hydrographic cableway is fixed in height and the lead fish is unstable after being connected to the traveling crane through a steel wire rope, resulting in errors in the measurement data.
