Description

Technical Field

[0001] The utility model relates to the technical field of traction machines, in particular to a hoisting mechanism of a traction machine of a hydropower station. Background Art

[0002] The existing traction machine hoisting equipment for hydropower stations drives the steel rope for hoisting operations through the traction wheel when in use. When the steel rope is hoisting a large volume and heavy cargo, the force on the rope itself is huge, and the rope is driven by the winding rotation inside the traction wheel. As a result, the steel rope needs to be continuously and regularly maintained and oiled by the staff when used for a long time, which is time-consuming and labor-intensive. For this reason, we propose a hydropower station traction machine hoisting mechanism. Utility Model Content

[0005] Preferably, the brushing cotton roller itself has an adsorption property, and when the lubricant in the storage cavity is introduced into the built-in groove through the liquid guide groove, the brushing cotton roller is in an adsorption and storage state for the lubricant.

[0006] Preferably, when the traction wheel drives the rope to rotate and move the rope inside the wire groove, the surface of the brushing cotton roller is wrapped and brushed with the outer periphery of the rope through the lubricant.

[0007] Preferably, a filling groove for filling the storage cavity with oil is provided on the top of the sleeve device, and a sealing plug for sealing the filling groove is provided inside the filling groove.

[0008] Preferably, an adapter slot adapted to the appearance of the rope is provided on the inner side of the winding groove, the adapter slot is an arc-shaped slot body, and the rope is connected by being engaged and wound with the inside of the winding groove through the adapter slot.

[0009] Beneficial Effects

[0010] The utility model provides a traction machine hoisting mechanism for a hydropower station, which has the following beneficial effects:

[0011] (1) A kind of hydropower station traction machine lifting mechanism, in this article, a sleeve device is installed on the top of the base and is sleeved on the outside of the rope. The interior of the sleeve device is provided with a rotatable brushing cotton roller in the built-in groove, and the storage cavity stores a storage cavity with lubricating oil. When the storage cavity is injected with oil, the lubricating oil can enter the built-in groove through the liquid guide groove and be absorbed by the brushing cotton roller. When the traction wheel is started to drive the rope to rotate for lifting, the rope will contact the brushing cotton roller when passing through the inside of the wire groove. As the rope moves, the brushing cotton roller will automatically brush the absorbed lubricating oil on the surface of the rope through the extrusion of the rope when rolling, so that when the rope and the inside of the winding groove are subjected to mutual force, the wear force between the traction wheel and the rope is reduced. The oil stored in the storage cavity can reduce the frequency of traditional maintenance, so as to achieve the effect of automatically brushing the rope itself with maintenance oil, which saves time and effort.

[0012] (2) In the hoisting mechanism of the traction machine of the hydropower station, the rope is driven by winding in the winding groove inside the traction wheel, and the inner side of the winding groove is provided with an adapter slot that is adapted to the appearance of the rope. The rope is limited by the engagement with the inner side of the winding groove through the adapter slot. When the traction wheel is started to drive the rope to be wound through the winding groove, the rope can increase the engagement stability with the inside of the winding groove through the adapter slot, so that the rope can stably drive the external cargo hoisting and avoid slipping, thereby achieving the effect of improving the driving force for cargo hoisting.
