[0001] The invention relates to the technical field of lifting devices, in particular to a steel structure dome hydraulic lifting device with a guiding and anti-deviation function. Background Art

[0002] In recent years, with the development of construction technology and the strong support of national policies, steel dome prefabricated buildings have been widely used and have been in a stage of sustained and rapid development in recent years. Many building materials and structural components used in prefabricated buildings have been put into mass production and use, winning social acclaim. In the construction of prefabricated gymnasiums, steel structure skeletons are widely used as roof structures. This type of steel structure roof has the advantages of good structural strength, light weight, energy saving, environmental protection and good durability. When installing the steel structure dome, a hydraulic lifter will be used to lift the steel structure dome, so that the process requirements for the installation of the steel structure dome can be met.

[0003] At present, the lifting device used for the steel structure dome will deviate during the lifting process due to the uneven ground when in use.

[0008] By adopting the above technical solution, when the base is placed on an uneven ground, the screw at one inclined end is adjusted to rotate downward during adjustment. When the screw rotates, it will move downward through the side plate. When the screw moves downward, it will drive the bottom block to move through the rotating block. In this way, the bottom block will gradually lift the inclined side of the base upward, and eventually the base will be in a horizontal state. In this way, when in use, the lifter can be kept in a horizontal state through this structure to achieve the function of preventing deviation.

[0019] 1. The present invention provides a steel structure dome hydraulic lifting device with a guiding and anti-deviation function. When the base is placed on an uneven ground, the screw at one inclined end is adjusted to rotate downward during adjustment. When the screw rotates, it moves downward through the side plate.

In this way, when in use, the lifter can be kept in a horizontal state through this structure to achieve the anti-deviation function.

[0020] 2. The present invention provides a steel structure dome hydraulic lifting device with a guiding and anti-biasing function. When the control button operation is completed, the squeezing of the protective cover is released, so that the first spring will be reset. When the first spring is reset, it will drive the cross rod to reset. When the cross rod is reset, it will drive the protective cover to move. When the protective cover moves, it will move through the docking column and the slider at the bottom. Finally, the protective cover will cover the outside of the control button, thereby protecting the control button when in use.

[0021] 3. The present invention provides a steel structure dome hydraulic lifting device with a guiding and anti-deviation function. When in use, the cover plate is installed on the surface of the top plate, and then the pull rod is loosened. At this time, the second spring will reset, and the second spring will drive the linkage plate to move when it resets. When the linkage plate moves, it will drive the clamping head to move, so that the clamping head will dock with the top plate, so that the cover plate can be installed on the top plate when in use, so as to reduce the damage to the top plate during use, thereby achieving the effect of reducing the loss of equipment.
