Description

Technical Field

[0001] The utility model belongs to the technical field of building steel structures, and in particular relates to a grid lifting bracket. Background Art

[0002] Grid lifting devices are an indispensable part of building construction. They provide important support for the efficient and safe construction of modern buildings by lifting and accurately positioning large steel structure grids.

[0003] Traditional grid lifting supports face a series of challenges and defects during construction. First, due to the lack of accurate monitoring and control systems, construction workers often find it difficult to understand the tension and lifting speed of the steel strands in real time, which leads to insufficient accuracy and controllability during the lifting process, increasing construction risks and safety hazards. In some cases, the inability to effectively monitor the distribution of lifting forces may lead to instability of the grid structure, or even serious accidents such as structural deviation or collapse.

[0004] Secondly, the traditional lifting bracket lacks a stable fixed connection point, such as an L-shaped fixed pressure plate, which makes the lifter susceptible to uneven forces during the lifting process, which not only affects the stability of the lifting, but may also cause premature wear or damage to the lifter. In addition, due to the lack of precise distance and height settings, the steel strand may be subjected to unnecessary wear during the export process, increasing the frequency of rope replacement and raising construction costs. Summary of the invention

[0005] The purpose of the utility model is to provide a grid lifting bracket, which realizes real-time monitoring and recording of steel strand tension and lifting speed by connecting a pull rope encoder with a central control system, thereby improving the accuracy and controllability of the lifting process and ensuring the safety and efficiency of the construction.

[0006] In order to achieve the above purpose, the specific technical solution of this application is as follows:

[0007] A grid lifting bracket comprises a supporting base, a horizontal lifting bracket is arranged on the supporting base, a vertical guide frame is arranged on the lifting bracket, a lifter is arranged on the lifting bracket, the bottom of the lifter is fixedly connected to the lifting bracket by four symmetrically arranged L-shaped fixed pressure plates, a steel strand is passed through the lifter, and a pull rope encoder is provided on the lifter.

[0008] Based on the above technical features, further, the rope encoder is connected to a central control system, which can monitor and record the tension and lifting speed of the steel strand in real time, and accurately control the lifter during the lifting process.

[0009] Based on the above technical features, further, a ground anchor is provided directly below the lifter, and a sky anchor is provided above the lifter, and the steel strand passes through the ground anchor, the lifter and the sky anchor in sequence, and then is led out along the guide frame.

[0010] Based on the above technical features, preferably, the distance between the guide frame and the lifter is 0.4m.

[0011] Based on the above technical features, preferably, a cross bar is provided at the top of the guide frame, and the cross bar is 1.5-2m higher than the sky anchor of the lifter, and the total height of the guide frame is 3.5m.

[0012] Based on the above technical features, preferably, the lifter is a hydraulic lifter or an electric screw lifter.

[0013] Based on the above technical features, preferably, the supporting base is equipped with an adjustment device, which can fine-tune the horizontality of the base to ensure the verticality of the lifting bracket and the stability of the entire lifting system.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] This application realizes real-time monitoring and recording of the tension and lifting speed of the steel strand by connecting the pull rope encoder with the central control system, thereby improving the accuracy and controllability of the lifting process and ensuring the safety and efficiency of the construction;

[0016] The L-shaped fixed pressure plate provides a stable fixed connection point for the lifter, ensuring the stability of the grid during the lifting process and preventing the structure from shifting or collapsing due to uneven lifting force or unexpected situations;

[0017] The precise distance between the guide frame and the lifter is 0.4m, the crossbar is 1.5-2m higher than the sky anchor of the lifter, and the total height of the guide frame is 3.5m, which ensures the smooth export and correct guidance of the steel strand, reduces the wear of the steel strand and the stress concentration of the structure, and prolongs the service life of the steel strand;
