Construction Safety Lifting Device

Abstract

A building construction safety lifting device comprises a bearing plate. The interior of the bearing plate is hollow, a transverse screw rod is arranged in the middle in the bearing plate, an internalthreaded sleeve is mounted in the middle of the screw rod in matched and sleeving modes, and positioning rings are mounted at the two ends of the internal threaded sleeve through bearings in a sleeving mode correspondingly; the positioning rings are fixedly connected with the inner wall of the bearing plate through first brackets, and rotation-stopping sleeves are mounted on the positions, closeto the two ends, of the screw rod in a sleeving mode correspondingly; the rotation-stopping sleeves are fixedly connected with the inner wall of the bearing plate through second brackets; and long-strip grooves are formed in the screw rod, inserting blocks are fixedly mounted in the inner walls of the rotation-stopping sleeves, the inserting blocks are inserted into the long-strip grooves, a transverse motor is fixedly mounted in the middle of the internal top of the bearing plate, a driving gear is fixedly mounted on an output shaft of the motor, a driven gear is fixedly mounted on the internal threaded sleeve in a sleeving mode, and the driving gear is matched with the driven gear in an engaged mode. The building construction safety lifting device is simple in structure, low in manufacturing cost and sensitive in reaction, and has the automatic balance adjusting function.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, in particular to a construction safety lifting device. Background technique [0002] On the construction site of high-rise buildings, the construction lifting platform is a peripheral protective facility set up to solve the vertical and horizontal transportation of construction personnel and building materials. The construction personnel can lift the construction lifting platform to the ideal height according to the work needs, which is convenient for the construction personnel to carry out construction in the most comfortable posture, which greatly improves the working efficiency and reduces the labor intensity. It solves the transportation problem of building materials; it can replace steel, bamboo, wooden scaffolding, electric hanging basket and integral climbing scaffolding, especially suitable for high-rise building exterior wall decoration, interior decoration or other high-r...

AI Technical Summary

Problems solved by technology

[0003] The existing construction lifting platform has complex structure, large size and high construction cost. Most of the lifting work is carried out through the cooperation of more than two independent power devices. When multiple independent power devices work out of sync, it is easy to cause the construction platform to tilt. The construction platform It is difficult for the staff on the platform to ensure safety when working, and the materials on the upper part are easy to fall. Most of the traditional construction lifting platforms do not have the function of automatically adjusting the platform to keep the level. During the lifting process of the traditional construction lifting platform, if multiple independent power devices The work cannot be synchronized, which will lead to the destruction of the construction lifting platform in severe cases
