Example Embodiment

[0026]Embodiment: A pressurized anti-skid system for hoisting long rails with an electric hoist, including a double-hook control system, an abnormality detection system, and a flat horizontal monitoring system. The electric hoist adopts a double-output scheme of a reducer. The other end can also be connected to the second reel of the low-speed shaft with another hook, and the low-speed shaft is extended to achieve the purpose of double lifting points, so that the electric hoist is suitable for lifting long rails, and the high-speed shaft can only bear the load. The length of the drum required by the lifting height requires no responsibility for the distance between the double lifting points. The rotation speed of the low-speed shaft is between 10 and 20r / min. The lifting rail is controlled by the double hooks together. The force and lifting free rotation angle are controlled, and the planetary reducer transmission scheme is used to realize double hook control. The planetary red...

Abstract

The invention relates to the technical field of electric hoist hoisting systems, and discloses a pressurizing anti-skid system for an electric hoist to hoist a long steel rail, the pressurizing anti-skid system comprises a double-hook control system, an anomaly detection system and a horizontal monitoring system, the electric hoist adopts a speed reducer double-output scheme, and a right end output shaft of a speed reducer is connected with a main winding drum; the purpose of double-lifting-point lifting is achieved by lengthening the low-speed shaft, so that the high-speed shaft only bears the length requirement of the winding drum required by the lifting height and does not bear the responsibility of the double-lifting-point distance, and the lifting efficiency is improved. The abnormity detection system comprises a motor fault detection system, a speed reducer fault detection system, a brake fault detection system, a winding drum device fault detection system and a steel wire rope fault detection system, the single-chip microcomputer compares processed data with preset numerical values in the system, and therefore real-time monitoring is achieved; the effect of ensuring safe operation of the electric hoist is achieved.

Description

technical field [0001] The invention relates to the technical field of hoisting systems for electric hoists, in particular to a pressurized anti-skid system for hoisting long rails with electric hoists. Background technique [0002] Electric hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage, docks and other places. The compact electric hoist whose motor axis is perpendicular to the axis of the reel adopts a worm gear transmission. Its disadvantages are: large length, large width, bulky structure, low mechanical efficiency, and difficult processing. Electric hoists are generally installed on single-girder cranes. , Overhead Cranes, Gantry Cranes, Suspension Cranes. With a little modification, it can also be used as a hoist. Therefore, it is an essential machine to i...
