Problems solved by technology

[0002] At present, most of the hoisting devices used in the construction industry are not equipped with emergency braking devices. When accidents such as wire rope breakage, power failure, overloading, etc. occur, the user cannot be rescued in time, causing the user's personal and property safety to be easily threatened. This is why there are so many reports of unexpected accidents in hoisting devices

Abstract

The invention provides a safe lifting device for construction. A first gear is fixedly connected to a motor, the two ends of a rotating shaft are provided with a rope roll and a second gear respectively, the two ends of the rope roll are each provided with a limiting plate, the left-end limiting plate is provided with a ratchet wheel, a pawl is fixedly connected with a wedge-shaped plate, and an outer cover is arranged on the wedge-shaped plate; an emergency braking switch is arranged on a connecting rod, an air cylinder is connected with a hinge pedestal in a hinged mode, a scanner is connected with a controller through a wire, a lower wedge-shaped plate arranged on the air cylinder makes contact with the wedge-shaped plate, a spring is connected with the wedge-shaped plate and the outer cover, the pawl is arranged on the ratchet wheel, and the first gear is meshed with the second gear. The safe lifting device is simple in structure, a steel rope speed display screen is arranged for observing the steel rope operation speed in real time, the air cylinder is adopted to push the pawl to brake, the bidirectional braking speed and the braking safety are high, and therefore the safe lifting device is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, in particular to a safety lifting device for construction. Background technique [0002] At present, most of the hoisting devices used in the construction industry are not equipped with emergency braking devices. When accidents such as wire rope breakage, power failure, overloading, etc. occur, the user cannot be rescued in time, causing the user's personal and property safety to be easily threatened. This is why there are so many reports of accidents in hoisting devices these days. Therefore, in order to improve the safety of the hoisting device and ensure personal safety more effectively, it is very necessary to invent a kind of construction safety hoisting device. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a safety lifting device for construction. The present invention has a simple structure, and...
