Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to hoist angle technology field, concretely relates to a fixed angle device. BACKGROUND
[0002] The angle is the component commonly used in the steel structure unloading and hoisting, and is used for protecting the edge of the hoisted object. In the traditional hoisting operation, the angle is generally of non-fixed structure, and the commonly used angle is an arc-shaped iron plate. The principle is to isolate the edge of the hoisted object and the lifting lock, increase the contact area of the lifting lock, protect the lifting lock, and prevent abrasion and cutting. However, the traditional angle has great defects. First, before the lifting lock such as the steel wire rope is hoisted tightly, the angle is in a relaxed state. In the process of gradually being stressed, the angle may be displaced or even dropped due to stress vibration, hoisted object shaking or rope friction. Lightly, the protection effect is reduced. Heavily, safety accidents such as hoisted object sliding, rope abrasion and rupture are caused. The angle needs to be placed again by the lifting machine. Second, during the process of placing the angle and tightening the steel wire rope, the worker may hold the angle by hand. If the steel wire rope suddenly slides, the worker's hand may be injured by the steel wire rope. In addition, the arc-shaped iron plate has poor contact with the contact surface of the hoisted object, and local stress concentration is easily generated, which causes the surface of the hoisted object to be scratched or the angle to be deformed and invalid.
