Lifting mechanism and street lamp hoisting equipment for constructional engineering

Abstract

The invention relates to a lifting mechanism and street lamp hoisting equipment for constructional engineering. The lifting mechanism comprises a cross beam and a lifting frame which penetrates through the cross beam and is connected with the cross beam in a sliding mode; the lifting frame is connected with a lifting driving mechanism installed on the cross beam; a mounting frame is hinged to theend, away from the lifting driving mechanism, of the lifting frame; a fixed plate is fixed to the side, away from the lifting frame, of the mounting frame; a fixing mechanism is arranged on the side,away from the mounting frame, of the fixed plate; the fixing mechanism is connected with a winding and unwinding assembly installed on the fixed plate through two traction ropes connected with the fixing mechanism; when the winding and unwinding assembly moves, the two traction ropes are wound and unwound correspondingly; a rack plate is further fixed to the cross beam; a gear is fixed to a rotating shaft connected with the lifting frame and the mounting frame; and when the gear is meshed with the rack plate, the mounting frame rotates in the moving process of the lifting frame.

Description

technical field [0001] The invention relates to the technical field related to construction engineering, in particular to a lifting mechanism and street lamp lifting equipment for construction engineering. Background technique [0002] Construction engineering refers to the general designation of various buildings and engineering facilities that provide the material and technical basis for human life and production. Construction engineering is an organized, purposeful and large-scale economic activity of human beings. Construction projects can be divided into three categories according to their natural attributes: architectural engineering, civil engineering, and electromechanical engineering. Construction engineering is an organized, purposeful and large-scale economic activity of human beings. It is an engineering project that forms comprehensive production capacity or exerts engineering benefits in the process of fixed assets reproduction. Construction works refer to t...

AI Technical Summary

Problems solved by technology

[0003] In road construction, it is generally necessary to install street lamps, and the installation of street lamps generally needs to be installed on the support rods, and the length of the support rods is long and the quality is heavy. During the erection process of the support rods, it is necessary to cooperate with the lifting mechanism to realize the installation. Existing The lifting mechanism can lift the support rod with a single head to achieve erection. Generally, it needs to be handled manually, which has potential safety hazards and complicated operation.
