Self-reinforcement clamp type lifting appliance

Abstract

The invention discloses a self-reinforcement clamp type lifting appliance. The self-reinforcement clamp type lifting appliance comprises two clamp arms, the two clamp arms are longitudinally arranged,and are hinged through a middle shaft, each clamp arm is divided into a handle end and a pressing end through the middle shaft, a wall plate is clamped to the pressing ends, a process hole is formedin the face of the wall plate, pressing discs are arranged at the two ends of the process hole, the pressing discs are hinged to the clamp arms, limiting holes are formed in the ends, making contact with the wall plate, of the pressing discs, and are horizontally arranged, a lifting shaft is inserted between the limiting holes, and the lifting shaft penetrates the process hole. The handle ends areprovided with two lifting cables, the two lifting cables are connected with the clamp arms, and the two lifting cables are jointly connected with a lifting ring. The technical problem about lifting and splicing of heat preservation light wall plates in assembly type buildings can be effectively solved, the structure is simple, and operation is easy.

Description

technical field

[0001] The invention relates to the field of spreaders, in particular to a self-energizing pincer spreader. Background technique

[0002] The spreader refers to the device for lifting heavy objects in the hoisting machinery. The most commonly used spreaders for lifting finished items are hooks and slings. Others include lifting rings, lifting suction cups, clamps and forks, etc., which are widely used in the lifting industry.

[0003] As the country attaches great importance to environmental protection, in order to reduce the pollution of the construction market to the environment, the country advocates and vigorously promotes prefabricated buildings. However, there have always been many imperfect problems in the production, hoisting, transportation and assembly of wallboards in prefabricated buildings. The present invention is a self-energizing clamp-type spreader used for hoisting light-weight wallboards in prefabricated buildings. It effectively solves t...
