Description

Wire rope electric block for metallurgical workshop

Technical Field

The invention relates to the field of steel wire rope electric hoists, in particular to a steel wire rope electric hoist for a metallurgical workshop.

Background

The steel wire rope electric hoist is a small-sized hoisting device with the advantages of compact structure, light weight, small volume, strong universality of parts and components, convenient operation and the like, is mainly used for various lifting, pulling, loading and unloading heavy objects, and upside-down welding of oil tanks, such as the installation and the movement of various large and medium concrete, steel structures and mechanical equipment, and is suitable for building construction companies, the civil and architectural engineering of factories and mines, the mechanical equipment of bridge construction, electric power, ships, automobile manufacturing, buildings, highways, bridges, metallurgy, mines, slope tunnels, hoistway treatment protection and other basic construction engineering. The motor is generally a cone-shaped motor, a locking brake is automatically locked after the motor stops, and the steel wire ropes matched with the motor comprise a phosphating coating steel wire rope, a galvanized steel wire rope and a smooth steel wire rope. The steel wire rope electric hoist comprises the following components: motor, drive mechanism, reel and wire rope. There are roughly four types of motors and reels, which are different from each other in position. The electric hoist with the motor axis vertical to the axis of the winding drum adopts a worm gear transmission device, so that the electric hoist is large in size in width, heavy in structure, low in mechanical efficiency and difficult to machine. The electric hoist with the motor axis parallel to the reel axis has the advantage of small height and length dimensions. The disadvantages are large width dimension, grouping, and complexity in manufacturing and assembling. The turning radius of the track is large. The electric hoist with the motor arranged in the winding drum has the advantages of small length and compact structure. The main defects of the motor are poor heat dissipation condition, poor grouping performance, inconvenient motor inspection, installation and maintenance and complex power supply device. The electric hoist with the motor arranged outside the winding drum has the advantages of good grouping performance, high generalization degree, easy lifting height change and convenient installation and maintenance. The disadvantages are: the length dimension is large.

When the existing steel wire rope electric block for the metallurgical workshop is used for hoisting large-scale workpieces in the metallurgical workshop, due to the fact that the workpieces are mostly provided with no proper hook which can be hung, the steel wire rope is often required to penetrate through the workpieces, then the steel wire rope electric block can hoist the large-scale workpieces through the steel wire rope, a problem can occur at the moment, namely, a hook head on the steel wire rope electric block is limited because no corresponding structure exists for the steel wire rope hung on the hook head, so that the steel wire rope hung on the hook head is easy to move, and the safe hoisting of the workpieces can be influenced.
