Description

Technical Field

[0001] The utility model relates to the field of construction platforms, in particular to a safety lifting construction platform for building construction. Background Technique

[0002] Building construction refers to the production activities in the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. In order to improve the construction efficiency and convenience, a lifting construction platform is usually required to transport workers and building materials.

[0003] A lifting construction platform is a hoisting machine for vertically transporting people or objects, which can be applied to high-altitude construction operations. However, when the existing lifting construction platform rises to a high place, due to the lack of positioning measures for the construction platform, the load on the lifting equipment for the construction platform is too large, so that the safety of the construction platform cannot be guaranteed. For this reason, we propose a safety lifting construction platform for building construction to solve the above problems. Content of the Utility Model

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In this device, a drive motor is arranged on the machine base of the support frame. The drive motor drives the wire reel to rotate, and the wire rope is wound and unwound by the wire reel, so that the wire rope drives the lifting platform between the support frames to lift. The lifting platform is connected to the bottom plate and the support frame through sliding rods, which can ensure the stability during the lifting process. The winding methods of the two wire reels for the wire rope are opposite, so that when the lifting platform lifts, the rotation direction of the drive motor is opposite, which can ensure the lifting safety. At the same time, a sliding electromagnetic plate is arranged at the bottom of the lifting platform. The electric push rod drives the electromagnetic plate to slide, so that the electromagnetic plate can contact the support frame. After the lifting platform lifts to the designated position, the electromagnetic plate is electrified and adsorbed on the support frame, which can reduce the load on the wire reel and the wire rope and ensure the safety of the construction platform.
