Crane for building construction

Abstract

The invention discloses a crane for building construction, and belongs to the technical field of building construction. The crane comprises a bearing plate, the front side wall and the rear side wall of the bearing plate are rotatably and slidably connected with first protection plates, and the left side wall and the rear side wall of the bearing plate are rotatably connected with second protection plates; the lower side wall of the bearing plate is fixedly connected with a plurality of supporting columns; a movable plate is arranged below the bearing plate, the movable plate is connected to the supporting columns in a sliding mode, and the supporting columns are sleeved with a plurality of first springs enabling the movable plate to reset; the movable plate and the bearing plate are jointly provided with a first driving mechanism and a second driving mechanism; a self-locking mechanism is arranged on the bearing plate; and the self-locking mechanism is used for limiting the second protection plates after the second protection plates rotate to a vertical state. The purposes of preventing objects from falling from high altitudes and facilitating loading and unloading can be achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a crane for building construction. Background technique [0002] my country's construction industry is booming, and some construction projects are blindly pursuing the construction cycle of the project, while ignoring the necessary and effective protective measures at the construction site. Therefore, construction safety accidents often occur, which greatly reduces the cost of the construction unit. Benefits: Among the many construction safety accidents, the most common ones are the safety accidents caused by falling objects hitting construction workers. Therefore, strictly controlling the dangerous performance of falling objects during construction can effectively reduce the incidence of construction safety accidents. [0003] In the construction site, the raw materials are transported at high altitude, and the metal plate is generally used to carry the raw material...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of construction crane, to solve the above-mentioned background technology proposed in the construction site, the general high-altitude transportation of raw materials, the use of metal plate carrying raw materials around the raw materials is not anti-falling, although this device is convenient for workers to Loading and unloading of raw materials, but when transporting raw materials at high altitudes, if encountering strong winds, the raw materials are likely to fall off at high altitudes, causing life danger to people on the ground; It is not affected by strong winds during high-altitude transportation, but the loading plate with protective plates is not conducive to the loading and unloading of raw materials by workers, so it will consume a lot of manpower and material resources.
