Safety lifting machine for building construction

Abstract

The invention discloses a safety lifting machine for building construction. The safety lifting machine comprises a lift car and a base, wherein guide wheel bases are fixedly arranged on two sides of the lift car; guide wheels are mounted in match inside the guide wheel bases; guide track are arranged inside the base; the guide wheels are mounted on the inner walls of the guide tracks in a contactmanner; the top of the lift car is connected with a pulley block through a steel wire traction rope; two ends of the pulley block are mounted in match with a mounting base at the top of the base through a bearing set; the input shaft of the pulley block is connected with the outer shaft of a motor; the motor is fixedly mounted with the base through the motor base; the input end of the of the motoris electrically connected with the output end of a single chip microcomputer. According to the safety lifting machine for building construction, the pulley block is additionally arranged, and two lifting ropes are adopted for traction, so that the safety can be ensured; moreover, a falling prevention structure is arranged on a side of the lift car, so that the lift car can be prevented from falling down actively in case of emergent falling.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a safety lift for building construction. Background technique [0002] At present, construction safety problems frequently appear in buildings. During the construction process of the main building project, it must be combined with the construction elevator. Used for vertical transportation, it is a dual-purpose elevator for carrying people and materials. It is also called an external elevator because it is attached to the outside of the main body of the building. In recent years, the use of elevators in high-rise buildings has become more and more common. However, due to the gap between the safety performance of the products and the general passenger elevators, and the poor working environment on the construction site, there are often potential safety hazards in the equipment. For the construction elevator, it is the only vertical transportation equipment that can...

Problems solved by technology

In recent years, the use of elevators in high-rise buildings has become more and more common. However, due to the gap between product safety performance and general passenger elevators, and the poor working environment on the construction site, there are often potential safety hazards in the equipment.

As for the construction elevator, it is the only vertical transportation equipment that can carry people on the construction site. Improper safety management may cause the ladder cage (also known as the car) to fall, causing accidents of mass death and mass injury

Most of the current construction hoists use a single rope, that is, a sling to lift and lift. Once the sling breaks, the consequences will be disastrous
