Technical Field

[0001] The invention relates to the technical field of steel pipe tower hoisting, in particular to operating equipment for steel pipe tower assembly. Background Art

[0002] Steel tube tower is a type of iron tower commonly used in the construction of power transmission line projects. It includes four-legged steel tube tower and single tube tower. It is generally used in line projects with high voltage levels, multiple circuits, complex climatic conditions or limited floor space.

[0003] A single steel pipe tower component weighs several tons, and flanges are provided at the upper and lower ends of the components. Safety and quality requirements are high during hoisting. The on-site hoisting of steel pipe tower components uses a wire rope + U-shaped ring lock method, which is not very safe and easily wears the galvanized layer of the component. It cannot be hoisted vertically, which is not convenient for the installation of the steel pipe tower. In view of this situation, it is necessary to develop a steel pipe tower assembly operation equipment to effectively ensure the quality of the components while improving safety and reliability.

[0008] The lifting mechanism is arranged between the outer side surface of the clamping mechanism and the outer side surface of the cable drum. The steel pipe tower assembly special operation equipment adopts an assembled self-locking supporting mechanism to quickly fix the upper end of the steel pipe tower, thereby realizing vertical lifting, and effectively solving the problem that the use of steel wire rope and U-shaped ring lock to lift the steel pipe tower is not safe and easy to wear the galvanized layer.

[0009] Furthermore, the clamping mechanism also includes a second support, a second stud and a second nut. The second supports are respectively arranged on the outer side surfaces of adjacent ends of four fixed blocks located in the same horizontal plane. A second stud is inserted between two adjacent second supports. Both ends of the outer side surface of each second stud are threadedly connected with a second nut, forming a fixing mechanism of the clamping mechanism.

[0014] Furthermore, the lifting mechanism also includes a mounting seat, a first U-shaped ring lock and a first steel cable ring. The mounting seats are equidistantly arranged on the outer side of the cable collection drum, and each mounting seat is installed with a first U-shaped ring lock. The first steel cable ring is respectively arranged in the middle of each first U-shaped ring lock, which is the installation element of the lifting mechanism.

[0015] Furthermore, the lifting mechanism also includes a second U-shaped ring lock and a second steel cable ring, the second U-shaped ring lock is respectively arranged at the upper end of each support arm, and the second steel cable ring is respectively arranged at the middle part of each second U-shaped ring lock, which is the installation element of the lifting mechanism.

[0019] 2. After the assembly is completed, the staff controls the external crane to lift the cable drum. Under the action of the steel cable and the support arm, the upper clamping block is only subjected to the horizontal internal pressure. Under the sliding limit of the limit column and the limit groove, the upper clamping block squeezes the rubber block, thereby achieving a stable clamping of the steel pipe tower. The lower clamping block is pulled up by the horizontal force and the plumb force, and the load is borne by the second stud and the second nut on the lower side, thereby lifting the steel pipe tower vertically. The steel pipe tower assembly equipment adopts an assembled self-locking supporting mechanism to quickly fix the upper end of the steel pipe tower, thereby achieving vertical lifting, effectively solving the problem of low safety and easy wear of the galvanized layer when lifting the steel pipe tower by wire rope + U-shaped ring lock.
