Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and in particular relates to a clamping device adapted to cylindrical piers of different diameters. Background Technology

[0002] In the construction of tall structures, especially in the construction of high bridge piers, hoisting operations are difficult and pose significant safety risks. Therefore, climbing devices are often used. These devices employ two clamps, one upper and one lower, to grip the pier and transport the necessary equipment or facilities to the top of the pier. Specifically, clamps are installed on the pier, and the maximum static friction generated by their clamping action overcomes the weight of the equipment or facilities. Two clamps are installed on each pier, and the climbing is achieved by alternately tightening and loosening the pier. However, existing clamps are only suitable for one type of pier diameter, requiring the manufacture of custom clamps for each diameter, resulting in substantial resource waste. Utility Model Content

[0003] The purpose of this utility model is to provide a clamping device that can adapt to cylindrical piers of different diameters, thereby reducing resource waste.

[0004] This utility model is achieved through the following technical solution: A clamping device adaptable to cylindrical piers of different diameters includes multiple arc modules that are hinged sequentially. Several pull-and-open jacks are detachably connected between the arc module at the first end and the arc module at the last end. Arc adjustment blocks of different thicknesses can be selectively installed on the inner side of the arc modules.

[0005] Furthermore, the arc module and the corresponding arc adjusting block are detachably connected by multiple connecting bolts and multiple connecting nuts.

[0006] Furthermore, the arc module is provided with several fixed brackets along its circumference, and the arc adjustment block is provided with several fixed brackets corresponding to the fixed brackets. The fixed brackets and fixed brackets are detachably connected by multiple connecting bolts and multiple connecting nuts.

[0007] Furthermore, end support plates are provided at both ends of the arc-shaped adjusting block.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: by installing arc adjustment blocks of different thicknesses on the arc module, the internal arc diameter of the arc module can be adjusted, thereby making it compatible with cylindrical piers of different diameters and reducing resource waste.

[0016] Please see Figures 1 to 4 , Figure 1 This is a flowchart illustrating the steps of the clamping device for cylindrical piers of different diameters according to this utility model. Figure 2 for Figure 1 AA section view, Figure 3 This is a schematic diagram of the hinge connection of the arc module in the clamping device of this utility model, which is adapted to cylindrical piers of different diameters. Figure 4 This is a schematic diagram showing the arrangement of the circular arc adjusting blocks in the clamping device adapted to cylindrical piers of different diameters according to this utility model. A clamping device adapted to cylindrical piers of different diameters includes multiple circular arc modules 1, which are sequentially hinged. Several pulling jacks 2 are detachably connected between the circular arc module 1 at the first end and the circular arc module 1 at the last end. Circular arc adjusting blocks 3 of different thicknesses can be selectively installed on the inner side of the circular arc module 1.

[0017] Multiple arc modules 1 are sequentially hinged to form a large-diameter outer clamp. In use, the large-diameter outer clamp is first opened, and arc adjustment blocks 3 of corresponding thickness are installed on each arc module 1 according to the diameter of the cylindrical pier 9 to form an inner clamp. The outer clamp and the inner clamp form a clamp device. By installing arc adjustment blocks 3 of different thicknesses on the arc module 1, the internal circular diameter of the clamp device is adjusted, forming a new clamp structure system with different diameters to be suitable for cylindrical piers 9 of different diameters, thus reducing resource waste.

[0018] In one embodiment, the arc module 1 and the corresponding arc adjusting block 3 are detachably connected by multiple connecting bolts 4 and multiple connecting nuts 5. The arc adjusting block 3 is installed onto the arc module 1 using the connecting bolts 4 and the nuts, which facilitates the replacement and installation of the arc adjusting block 3.

[0019] In one embodiment, the arc module 1 is provided with a plurality of fixed supports 6 along its circumference, and the arc adjusting block 3 is provided with a plurality of fixed brackets 7 corresponding one-to-one with the fixed supports 6. The fixed supports 6 and the fixed brackets 7 are detachably connected by a plurality of connecting bolts 4 and a plurality of connecting nuts 5. This arrangement facilitates the installation between the arc module 1 and the arc adjusting block 3. Furthermore, the frictional force of the arc adjusting block is transmitted to the corresponding arc module 1 through the brackets 7 and the fixed supports 6, thus completing the force transmission and enabling the inner and outer clamps to form an integral force-bearing structure, achieving the function of safe and universal use for variable diameter applications.

[0020] In one embodiment, the two ends of the arc-shaped adjusting block 3 are respectively provided with end support plates 8. The support plates 8 can more effectively transfer the force of the outer clamp to the inner clamp, so that the inner clamp can better hold the cylindrical pier 9.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
