Problems solved by technology

[0003] Building construction elevators in the prior art are generally not equipped with safety protection devices in order to save costs. Once the elevator encounters equipment or human factors, it is easier to induce the elevator car to fall, resulting in equipment damage and casualties, which has a greater safety hazard

Embodiment

[0021] Reference Figure 1-4 , A construction elevator safety protection mechanism, including a protective foundation pit 1, an elevator protective cover 2 and an elevator body 3. The elevator protective cover 2 is vertically installed on the inner wall of the protective foundation pit 1, and the elevator body 3 is located on the elevator protective cover In the housing 2, the inner wall of the elevator protective cover 2 is fixedly fixed with a fixed friction strip 5 arranged vertically. The fixed friction strip 5 always maintains a clearance fit with the two friction plates 6 during the normal operation of the elevator body 3. The outer wall is symmetrically fixed with a friction plate 6 with respect to the fixed friction strip 5. The inner top of the elevator body 3 is fixed with a piston cylinder 10 and a sliding varistor 14 at the corresponding position of one of the friction plates 6. The piston cylinder 10 is provided with a heat conducting plug 11 With the piston 19, on...

Abstract

The invention discloses a safety protection mechanism for a building construction elevator. The safety protection mechanism comprises a protection foundation pit, an elevator protection housing and anelevator body. The elevator protection housing is vertically arranged on the inner wall of the protection foundation pit. The elevator body is located in the elevator protection housing. The inner wall of the elevator protection housing is fixedly connected with a vertically-arranged fixed friction strip. The outer wall of the elevator body is fixedly connected with friction plates symmetricallyabout the fixed friction strip. The position, corresponding to one friction plate, of the inner top of the elevator body is fixedly connected with a piston barrel and a slide rheostat. The safety protection mechanism has the advantages that the safety protection mechanism is additionally mounted for the building construction elevator, once the elevator body falls due to equipment or human factor problems, heat is generated through contact between the fixed friction strip and the friction plates to reduce the falling speed of the elevator body, a memory metal rod is in contact with an electricconduction ring, a circuit is forced to ascend at the communicating position, the situation of equipment damage and casualties caused by the too high falling speed is avoided, and high safety is achieved.

Description

Technical field [0001] The invention relates to the technical field of building construction elevators, in particular to a safety protection mechanism for building construction elevators. Background technique [0002] The construction elevator for building is a kind of machinery that adopts rack and pinion meshing method or wire rope hoisting method to make the cage move vertically or inclined to transport people and materials. Building construction elevators are manned and cargo construction machinery often used in buildings, mainly used for interior and exterior decoration of high-rise buildings, bridges, chimneys and other buildings. Because of its unique box structure, the construction personnel can ride comfortably and safely. The construction hoist is usually used with a tower crane on the construction site. [0003] The building construction elevators in the prior art are generally not equipped with safety protection devices in order to save costs. Once the elevator encoun...
