Description

Technical Field

[0001] The utility model relates to the technical field of communication facilities, in particular to a plug-in type single-tube tower disassembly hydraulic device. Background Art

[0002] In order to ensure signal coverage, communication towers are usually of high height. For ease of manufacturing and transportation, existing communication single-tube towers adopt a multi-section structure, and multiple sections of the barrel are spliced ​​in sequence. Single-tube towers sometimes need to be disassembled due to maintenance and facility relocation. When separating the segments of existing single-tube towers, it is often necessary to apply an axial separation force. The current existing technology usually uses a crane to provide a pulling force from a high place to separate the segments of the single-tube tower from each other, or even only uses simple tools such as crowbars to perform related operations manually. The former is difficult to accurately control the direction of force, and it is easy to generate transverse force during the implementation process, resulting in uneven stress distribution of the segmented matching parts of the single-tube tower, and even causing structural damage. The latter is more difficult to operate and has a higher safety risk. Therefore, the industry still needs a more suitable plug-in single-tube tower disassembly hydraulic device and related methods of use. The utility model patent with announcement number CN218668779U discloses a segmented tube communication tower, whose tube body adopts a splicing structure of tube segments and tube slices. During transportation, it can be disassembled into a 120-degree tube slice structure for stacking, which greatly reduces the occupied space and transportation costs. However, this utility model is not mainstream in the industry, and its solution for disassembling a single-tube tower is not of universal significance. Utility Model Content

[0003] The prior art usually uses a crane to provide a pulling force from a height to separate the segments of the single-tube tower from each other. The direction of the force is difficult to control accurately, and transverse force is easily generated during the implementation process, resulting in uneven stress distribution in the segmented matching parts of the single-tube tower, and even structural damage. Even using only simple tools such as crowbars to separate the segments of the single-tube tower makes the operation more difficult and the safety risks are higher. In order to overcome these defects, the utility model provides a plug-in single-tube tower disassembly hydraulic device, which can implement the segmented separation operation of the single-tube tower more accurately, labor-saving, conveniently and quickly.

[0004] The technical solution of the utility model is: a plug-in single-tube tower disassembly hydraulic device, the single-tube tower includes a plurality of tower body segments and the adjacent tower body segments are plug-in connected, the plug-in single-tube tower disassembly hydraulic device includes a hydraulic cylinder and a thrust part, the cylinder body of the hydraulic cylinder is installed on a tower body segment, the thrust part is connected to another adjacent tower body segment, and the output end of the hydraulic cylinder is connected to the thrust part. The utility model provides an axial driving force through the hydraulic cylinder to axially separate the adjacent tower body segments. In this process, the driving force output by the hydraulic cylinder is stable and accurate in direction, and the force transmission efficiency is high. It is not easy for the single-tube tower to bend under the action of the transverse force, so that the stress distribution of the segmented matching part of the single-tube tower can be uniform, effectively preventing structural damage. The utility model can replace manpower to complete the segmented separation operation of the single-tube tower, reducing the difficulty of operation and safety risks.

[0006] As an alternative, the cylinder body of the hydraulic cylinder is hinged on the tower body segment, and the output end of the hydraulic cylinder is hinged on the thrust part. The cylinder body and the output end of the hydraulic cylinder are both hinged to the corresponding tower body segment, so that the hydraulic cylinder can make a certain degree of adaptive adjustment when working, which can reduce the installation accuracy requirement of the hydraulic cylinder.

[0007] Preferably, a longitudinal mounting rod is installed on the tower body segment, and the cylinder body and the thrust part of the hydraulic cylinder are installed on the corresponding longitudinal mounting rod. The longitudinal mounting rod provides a mounting support point for the hydraulic cylinder and the thrust part on the tower body segment.

[0008] Preferably, a reinforcing rib is provided between the longitudinal mounting rod and the thrust portion, which can improve the connection strength between the longitudinal mounting rod and the thrust portion, so that the hydraulic cylinder has a stronger ability to withstand the reaction force when outputting power.

The two symmetrically arranged hydraulic cylinders can balance the force application and force reception, and accurately and quickly implement the segment separation operation of the single-tube tower.

[0010] Alternatively, there are at least three hydraulic cylinders evenly distributed around the tower segment axis.
