Anti-falling wall-attached elevator for construction site

Abstract

The invention discloses an anti-falling wall-attached elevator for a construction site. The anti-falling wall-attached elevator comprises a main frame body, a lifting frame, an elevator main body, ananti-falling structure and a protective fence, wherein a wall-attached mounting frame is arranged on the back of the main frame body, elevator guide rails are arranged on the left side and the right side of the main frame body, two speed reducing motors are arranged inside the lifting frame, a counterweight block is hung inside the main frame body through a sling, the anti-falling structure is arranged at the top of the elevator main body, and a sliding convex block is arranged on one side, close to the main frame body, of the elevator main body. According to the anti-falling wall-attached elevator for the construction site, a rack, the anti-falling structure, a main gear and an auxiliary gear are arranged, when the falling speed of the elevator main body is too high, a centrifugal block overcomes the elastic force of a pressure spring piece to be thrown outwards, a brake drum is driven to rotate, the brake drum can move towards the right side when rotating on a screw rod, moreover, acopper nut is driven to move rightwards, the copper nut presses a disc spring, the process of moving the brake drum rightwards is slowed down, and the purpose of braking is achieved.

Description

technical field [0001] The invention relates to the technical field of wall-attached elevators, in particular to a fall-preventing wall-attached elevator for a construction site. Background technique [0002] Construction site wall-attached elevators are usually called construction elevators, and can also be called outdoor elevators, construction site hoisting cages, construction elevators are mainly used in various types of urban high-rise and super high-rise buildings, and are often used in construction for manned and cargo construction. Machinery, because such a building height is very difficult to use well-tac-toe frames and gantry frames to complete the work, so construction hoists are needed. [0003] However, construction elevators on construction sites are generally used to carry people or carry heavy items upwards, so the safety of construction elevators is particularly important. In general construction elevators, the speed of construction elevators is controlled b...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of anti-fall elevator attached to the wall of the construction site, to solve the problem that the environment of the construction site proposed in the above-mentioned background technology is generally poor, and it is not enough to monitor the speed of the elevator by a speed limiter alone
