Description

Technical Field

[0001] The utility model relates to the technical field of jacking devices, in particular to an assembled anti-eccentric load jacking device. Background Art

[0002] The design concept of assembly can improve the installation and disassembly efficiency of the device and adapt to different working scenarios and requirements. The anti-eccentric load function is to ensure the uniform distribution of force during the jacking process and avoid structural damage or jacking failure caused by uneven force. Specifically, the background art of the assembled anti-eccentric load jacking device may involve the following aspects: the progress of materials science: enabling the selection of more suitable materials to manufacture each component of the device to meet requirements such as strength, durability, and light weight. The improvement of manufacturing processes: for example, high-precision machining technology can ensure the dimensional accuracy and fit accuracy of assembled components, improving the overall performance and reliability of the device. The increasing requirements for jacking accuracy and stability: requiring a more precise control and adjustment system to achieve the uniform distribution of force and accurate control of direction during the jacking process. The application of intelligent control technology: real-time monitoring of various parameters during the jacking process, such as force and displacement, through sensors, and automatically adjusting the jacking force or performing corresponding control operations according to the feedback information to improve the jacking accuracy and safety. Different assembled anti-eccentric load jacking devices may have different focuses and innovation points in terms of background art for specific application scenarios and engineering requirements. In actual applications, detailed design, analysis, and tests are also required according to specific situations to ensure that the device can complete the jacking task safely and effectively. Publication No.: CN212983611U discloses a jacking device, including: a guide rail, a slider, and a lateral jacking mechanism. The slider is slidably connected to the guide rail. The guide rail is used to support the middle beam, and the slider is used to support the side beam. The lateral jacking mechanism is installed between the middle beam and the side beam. The tail end of the lateral jacking mechanism abuts against the side wall of the middle beam, and the head end of the lateral jacking mechanism abuts against the side wall of the side beam. Since the slider is slidably connected to the guide rail, the side beam will laterally move away from the middle beam. By controlling the elongation of the lateral jacking mechanism, the distance between the middle beam and the side beam can be adjusted. The device used in the lateral movement process is simple, low in price, and not affected by the construction environment. The risk coefficient during the lateral movement of the side beam is low, and the operation is convenient and simple. However, for the above-mentioned equipment, when applying the jacking force, a support rod is used for jacking operation, and the fixity is relatively low. The jacking material may tilt or shift, which needs to be improved. Summary of the Utility Model
