Description

Technical Field

[0001] The utility model relates to the technical field of rope supporting wheels, and specifically discloses a lifting type rope supporting wheel. Background Art

[0002] The rope supporting wheels (rollers) on the inclined shaft haulage road in a mine are devices for reducing the frictional resistance of the hoisting steel wire rope and reducing wear. If the rope supporting wheels (rollers) are complete and rotate flexibly, the service life of the steel wire rope can be extended, and the load of the winch and the maximum static tension of the steel wire rope can be reduced. If the rope supporting wheels (rollers) do not rotate and are ground into deep grooves by the steel wire rope, the running direction of the steel wire rope will be restricted. If the steel wire rope suddenly jumps out of the groove, it will seriously affect the safety of nearby personnel, and will also suddenly accelerate the mine car. If personnel are lifted, a great impact will be felt.

[0003] To solve the above problems, the publication number CN221521922U discloses a lifting type rope supporting wheel device, including a rope supporting wheel and a cylinder. The rope supporting wheel is installed on a rope supporting wheel base, the cylinder is welded on a cylinder base, and the upper end of the cylinder is connected to the rope supporting wheel base. With this solution, through the setting of the cylinder, the problems of the steel wire rope shaking, jumping, and the steel wire rope rubbing against the pusher slideway caused by the too long flat roadway distance at the upper yard of the inclined lane lifting location are solved.

[0004] However, the base is under the action of radial force for a long time, and it is easy to crack and break at the connection between the base and the guide rod and the cylinder, affecting the service life; and the steel wire rope will still shake and jump at the rope supporting wheel and break away from the rope supporting wheel to rub against the pusher slideway.
