Description

Technical Field

[0001] The utility model relates to the technical field of liftable brackets, in particular to a liftable bracket for construction. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, living, learning, and public activities. During the construction of construction projects, construction materials need to be transported from low places to high places. In order to facilitate the operation, lifting brackets are often needed.

[0003] In the prior art, the lifting device has a simple structure, and the lifting bucket is lifted by winding a steel cable. As the lifting bucket drives the construction materials upward, the lifting bucket may shake during the upward movement. When the transported items are large and long, such items cannot be limited, resulting in the risk of falling during transportation, which is prone to safety hazards. Therefore, we propose a lifting bracket for construction. Utility Model Content

[0004] The main purpose of the utility model is to provide a hoistable support for construction, which can effectively solve the problems in the background technology.

The two mounting blocks are respectively slidably connected in the mounting grooves on both sides, and the mounting block on the left is threadedly connected to the No. 1 screw rod, and the mounting block on the right is threadedly connected to the No. 2 screw rod. Protective components are slidably connected to the front and rear ends of the loading platform, and the two protective components are symmetrically arranged.

[0010] Preferably, both front and rear ends of the loading platform are provided with slide grooves, and the inner walls of the two slide grooves are provided with two spring grooves.

[0011] Preferably, the protective assembly includes an adjusting block, which is slidably connected in a slide groove, and one end of the adjusting block is fixedly mounted with two return springs, and the ends of the two return springs away from the adjusting block are fixedly mounted to the inner wall of the spring groove, and the end of the adjusting block away from the return spring is fixedly mounted with a protective plate, and the opposite ends of the two protective plates are fixedly mounted with rubber pads.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting up a lifting mechanism, the No. 2 screw and the No. 1 screw are threadedly connected to the mounting block to drive the stage to move up, thereby driving the construction materials to be lifted and transported upward, replacing the traditional steel cable to lift the stage. The transmission is stable and the lifting is smooth. At the same time, the mounting blocks on both sides are slidably connected in the mounting groove to limit and guide the stage, thereby improving the stability of the stage during the lifting process and avoiding the problem of shaking and falling of the construction materials on the upper end of the stage.
