Description

Technical Field

[0001] The invention relates to the field of iron tower installation design, and in particular to a guide rod type tower assembly platform lifting device and a lifting method thereof. Background Art

[0002] In the current tower assembly construction, there are three main tower assembly methods: internal suspension and external wire holding pole tower assembly, tower crane tower assembly and internal wire disassembly assembly technology. Among them, internal suspension and external wire holding pole tower assembly is the mainstream tower assembly method in China. It is the most widely used and has the highest technical proficiency, but it is still difficult to meet the requirements of UHV projects in terms of safety, reliability and mechanization level. When tower assembly operations are carried out under steep terrain conditions in areas such as western Sichuan, there are poor transportation conditions, and heavy equipment such as double horizontal arms and double rocker arms cannot be transported to the site. When the site for suspended holding pole tower assembly is narrow, it is impossible to arrange the control rope. At the same time, various control ropes cannot obtain effective force angles during tower assembly, so that the force state of the holding pole cannot be effectively controlled. These problems have greatly increased the safety risks and difficulties of tower assembly. In these traditional tower assembly operations, construction workers need to step on the iron tower bracket to work, which is very dangerous. Therefore, there is an urgent need for a method to provide construction workers with safe operations. Summary of the invention

[0003] The present invention aims to solve the problem of working on a tower position that cannot meet the conditions for using heavy equipment in the prior art. The invention aims to provide a guide rod type tower assembly platform lifting device and a lifting method thereof. The self-climbing platform can be suitable for a construction work platform for tower assembly construction of a Ganzi Tower under steep terrain. At the same time, the platform has a self-climbing function, which eliminates uncontrollable factors and ensures the safety and feasibility of the tower assembly method in mountainous areas. When it is used in complex terrain, it can better solve the above-mentioned problems, greatly meet actual needs, and has progressive significance.

[0004] The present invention is achieved through the following technical solutions:

[0010] In order to improve the guiding stability, guide rods are provided on both sides of the main material of the iron tower.

[0011] As a specific structure of a guide rod mounting seat, the guide rod mounting seat is used to clamp the main material of the iron tower therein; through holes for the guide rods to pass through are arranged on both sides of the guide rod mounting seat.

[0012] As a connection method between the guide rod and the guide rod mounting seat, a stop ring is sleeved on the portion of the upper end of the guide rod extending out of the upper guide rod mounting seat;

[0013] The lower end of the guide rod has a plurality of jacks perpendicular to the guide rod along its length direction, and the jacks are used to insert fixing pins, and both ends of the fixing pins can extend out of the guide rod. In this scheme, through holes are set on both sides of the guide rod mounting seat, so that both ends of the guide rod can slide out of the through holes, which can improve the lifting efficiency and extend the length of the guide rod, so that the guide rod has a sufficient length.
