Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0020] A climbing method of a roller shutter-type steel pipe pole hoop. The hoop is composed of a plurality of single-section roller blinds hinged head to tail in turn. The single-section roller blind has two types: a pedal part and a handle part. The specific structure is as follows:
[0021] For the schematic diagram of the pedal part, please refer to the attached Figures 1 to 3 As shown, it includes steel plate 5, rubber pad 6, outer layer hinged plate 1, inner layer hinged plate 3 and pedal 2, and a rubber pad 6 is fixedly installed in the middle of the lower end of the rectangular steel plate to prevent slipping through screws 7, and is fixed at intervals on the upper end of one side of the stee...

The invention relates to a roller blind type steel pipe pole hold hoop. The roller blind type steel pipe pole hold hoop is formed by a plurality of single roller blinds hinged with one another end to end in sequence. The specific structure of each single roller blind comprises a steel sheet, a rubber mat, outer-layer hinged plates, inner-layer hinged plates and an extension part; the rubber mat is fixedly installed in the middle of the lower end of the rectangular steel sheet through a screw; the outer-layer hinged plates are fixedly installed at the upper end of one side of the steel sheet in a spaced mode; the inner-layer hinged plates are fixedly installed at the upper end of the other side of the steel sheet in a spaced mode; the outer-layer hinged plates and the inner-layer hinged plates are all provided with hinged shaft holes; and the extension part is fixedly installed in the middle of the upper end of the steel sheet. The roller blind type steel pipe pole hold hoop adopted by the invention is convenient to assemble and disassemble, the multi-roller-blind type structure is adopted, the hold hoop can be assembled freely and is suitable for steel pipe poles of various diameters, and the situation that a plurality of hold hoops with different diameters need to be prepared due to the fact that the diameters of the steel pipe poles are different is avoided; and the hold hoop has very large using spaces during electric power construction even steel pipe pole assemblage construction of other industry.
Description
technical field [0001] The invention belongs to the technical field of transmission line iron tower assembly, in particular to a rolling curtain type steel pipe pole hoop and a climbing method. Background technique [0002] At present, the steel pipe tower of the UHV transmission line can reach a maximum of more than 100 meters. In order to ensure the mechanical properties, the tower material is in the form of a steel pipe rod with a large diameter. The diameter of the steel pipe rod at the foot of the tower can reach 1400mm-2000mm. The steel pipe pole is made of multi-section connections, the longest single section length is 11 meters, and the connection parts are all in the form of flange connection. In order to facilitate climbing and fastening of flange bolts, one side of the steel pipe pole is equipped with a ladder or spikes. However, since only one end is equipped with climbing facilities, the bolts cannot be tightened at the part where the flange is far away from th...
