Abstract
The crane steel rope blanking winding device comprises a winding device, a separable coupler and a roller, wherein the winding device consists of a motor, a brake wheel coupler, a brake, a speed reducer and a winding drum; the separable coupling consists of a screw, a separable coupling and a passive end. One end of the output end of a speed reducer in the hoisting device is connected with the winding drum, the other end of the output end of the speed reducer is connected with the driving end of the separable coupling, and two holes in the driving end are fixed by pins. The drum can be pushed directly onto the hoist mechanism, connected by a separable coupling and then positioned with a set screw, and then one end of the steel cable is fixed to the drum rope clip. The utility model provides a hoist can reduce intensity of labour at the inconsistent problem of steel cable spare part length that exists before changing the steel cable process, shortens maintenance duration, improves maintenance efficiency.
Description
Technical Field
The utility model belongs to hoisting equipment, which is a hoisting machine steel rope blanking and winding device for metallurgy.
Background
Cranes are one of the important pieces of equipment in the steel making process. Because the molten metal is hoisted, the requirement on the safety coefficient of the crane is high. The steel rope of metallurgical crane consists of four steel ropes, wherein the steel rope belongs to a piece which is changed periodically, the safety coefficient of the steel rope is required to be large, and the steel rope is selected. Because the hoisting height is high, the length of the steel rope is long, several steel ropes of the crane are required to be as long, otherwise, after the crane is replaced, the balance frame of the hoisting mechanism can cling to the balance frame seat, the steel rope needs to be adjusted, and the time for overhauling and replacing is seriously influenced. How to guarantee that four steel cable spare parts unloading length is unanimous is bothering the maintainer always, causes very big restriction for production, has also brought very big risk for overhauing.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hoist steel cable unloading coiling mechanism solves the inconsistent problem of steel cable spare part length that the hoist exists before changing the steel cable process, shortens the repair time, improves maintenance efficiency.
The utility model provides a technical scheme that its technical problem adopted is:
a steel rope blanking winding device of a crane comprises a winding device, a separable coupler and a roller, wherein the winding device comprises a motor, a brake wheel coupler, a brake, a speed reducer and a winding drum, a driving end is in interference connection with an output shaft of the speed reducer, a pin penetrates through the driving end to be in transition connection, and a driven end is in interference connection with the roller.
One end of the output end of a speed reducer in the hoisting device is connected with the winding drum, the other end of the output end of the speed reducer is connected with the driving end of the separable coupling, and two holes in the driving end are fixed by pins. The steel rope blanking and winding device of the crane can be used as a normal winding device in daily life, and can be used as a steel rope when a spare steel rope is blanked.
The roller can be directly pushed onto a winch mechanism, is connected through a separable coupling 6 and then is positioned by a positioning screw 8; one end of the steel cable is then fixed to the drum 7 rope clip. The winding device drives the drum to wind the new steel rope onto the drum through the electric control system.
The using method comprises the following steps: the new steel rope is firstly transported to a steel rope blanking place by a forklift, and then the new steel rope is blanked to the required length. Because the steel ropes are not straight in the blanking process, the four steel ropes are generally different in length, one end of each steel rope is bound by a rope clamp at the position with the same length, the four steel ropes are connected by an equal-length traction steel rope and a forklift, the four steel ropes are dragged to be straight, and then the other three steel ropes are cut to be the same length by taking the shortest steel rope as a reference at the other end of each steel rope. This ensures that the four steel cords are the same length. Then put the cylinder on hoist mechanism, through the coupling joint hoist engine that can dismantle, fix steel cable one end to the cylinder again, through automatically controlled with the new steel cable of hoist engine automatic winding coil to the cylinder on, realize semi-automatization, make things convenient for transporting of steel cable spare part.
The utility model has the advantages that: reduce maintainer's working strength, reduced the operation risk of overhauing, improve work efficiency, the practicality is strong.
