Automatically adjusting pole climbing device with Y-shaped box and telescopic hook

Abstract

The pole climbing device includes two, right and left, symmetrical parts, and each part consists of one Y-shaped box assembly and one rack type telescopic hook. The Y-shaped box assembly consists of one pedal device with helical arched clamp and obliquely swing unhooking unit and one driving box. The rack type telescopic hook includes one bent part and one straight part, one side of the straight part has rack meshed with two-directional driving ratchet while the other side has continuous positioning notch for inserting and positioning the safety card in the driving box. The present invention is used in automatic pole climbing and is suitable for use in climbing 6-15 m high pole of different size.

Description

technical field [0001] The invention relates to a utility pole climber, in particular to a fast and safe automatic telescopic pole climber in which a pedal device shaped like a "sheep" force distribution line drives a telescopic hook rack through a power box. Background technique [0002] In recent years, with the rapid development of electric power industry and optical cable communication transmission industry, except for the erection of high-voltage iron towers in very few areas, most of them are 9m-15m high-voltage poles and 7m-9m communication poles, carrying high-voltage cables and communication poles. Transmission cables are extended to all parts of the world along with roads. Our country has a vast territory. The power lighting poles below 12m and the communication poles below 9m are spread over towns and villages according to tens of meters. In various natural villages, there are scattered electric poles, across mountains and rivers, through forests and wilderness, ...

Problems solved by technology

The safety basis of the sleeve-type telescopic foot buckle is based on the clamping force generated by the body weight acting on the sleeve and the torsion of the straight bar of the iron hook, and the product itself has extremely poor mechanical properties and requirements for the operating environment, such as oil , water, mud, rain, etc., if it enters the sleeve, it will slip immediately and lose safety guarantee; the upper and lower decoupling methods (see image 3 B) Automatic retractable type with side gear drive (see Figure 7A ) due to various factors that have not been considered comprehensively, the decoupling and reliable transmission of the side rack and ratchet cannot be realized as desired. The side rack is riveted and welded on the hollow tube, which does not meet the mechanical characteristics requirements of high-altitude operation products. And the basic requirements of process design, so in the experiment, the connection between the side rack and the hollow tube is often stuck because the dimensional tolerance of the normal working displacement of the ratchet cannot be guaranteed, making it impossible to drive reliably and realize automatic expansion and contraction
