Transmission device for feeding of lifting cage of construction hoist

Abstract

The invention discloses a transmission device for feeding of a lifting cage of a construction hoist. The transmission device comprises a bottom plate; a groove is formed in the upper portion of the bottom plate; rotating discs are arranged on the inner walls of the two sides of the groove, and movably connected with the inner walls of the groove; one of the rotating discs is connected with a driving device; one side of each rotating disc is fixedly provided with a transmission rod; the transmission rods are parallel to the tangent lines of the rotating discs; straight rods are movably connected to the two ends of the transmission rods; a folding rod is movably connected to the other end of each straight rod; a first fixing rod is arranged on a joint in the middle of each folding rod; and the two ends of the first fixing rods penetrate through the folding rods and extend out to be fixedly connected with the inner walls of the groove. The transmission rods and the straight rods are driven to move synchronously through rotation of a servo motor, the folding rods can rotate by a larger margin through the limiting effect of the first fixing rods, and the whole transmission system is simple, efficient, stable and reliable.

Description

technical field [0001] The invention relates to the technical field of construction elevators, in particular to a transmission device for loading cages of construction elevators. Background technique [0002] The construction hoist is a common construction equipment, which vertically lifts and transports people or materials in a large area, and is a construction machinery with a high probability of accidents. With the continuous rapid growth of my country's economy and the continuous expansion of urban construction, the production and sales of construction elevators have grown rapidly. With the increase of construction sites, the difficulty and complexity of construction have increased, resulting in more and more serious safety problems. Since construction elevators are mainly used in various types of urban high-rise and super high-rise buildings, it is very difficult for such building heights to use well-shaped frames and gantry frames to complete operations.

With the increase of construction sites, the difficulty and complexity of construction have increased, resulting in more and more serious safety problems

Since construction elevators are mainly used in various types of urban high-rise and super high-rise buildings, it is very difficult for such building heights to use well-shaped frames and gantry frames to complete operations. Physiological and psychological pressure will be great, especially the process of carrying out the materials transported in the cage at high altitude. It is very inconvenient to manually lift materials such as coils and pipes. will seriously affect the state of the workers
