Crawling ladder for leaning of columnar structure

Abstract

The invention relates to the technical field of crawling ladder fixing, and particularly relates to a crawling ladder for leaning of a columnar structure. The crawling ladder comprises a crawling ladder body, a fixing mechanism, an adjusting mechanism, a connecting mechanism, a pressing mechanism, a protecting mechanism and an abutting mechanism. The fixing mechanism and the crawling ladder body are detachably mounted and fixed conveniently through the connecting mechanism, subsequent replacement or use in other areas is facilitated, and the using practicability is improved; after the ladder leans, through driving of the pressing mechanism, the fixing mechanism and telegraph poles are clamped and fastened, and thus the crawling ladder is more stable; under the effect of the adjusting mechanism, the telegraph poles of different sizes are clamped and adjusted conveniently; the abutting mechanism is mounted in the fixing mechanism, thus the telegraph poles are abutted and fastened advantageously, and meanwhile the telegraph poles of different sizes are clamped and abutted advantageously; and the protecting mechanism is mounted at the bottom of the crawling ladder body, thus the crawling ladder body is closely attached to the ground, friction force is increased, and the crawling ladder body is placed stably and is not prone to sliding.

Description

technical field [0001] The invention relates to the technical field of ladder fixing, in particular to a ladder for leaning on a columnar structure. Background technique [0002] Ladders are also called climbing ladders, a tool for daily life. The tool consists of two long thick poles as sides, and a horizontal bar suitable for climbing is crossed in the middle. It is used for climbing. Ladders are divided into lifting single ladders and lifting herringbone ladders. There are many kinds of ladders , as an auxiliary facility of the city inspection shaft in the city, the ladder material has been made of steel for a long time, but the traditional metal ladder is very easy to use in many harsh environmental conditions, such as manholes, tunnels, chemical companies, rainy and humid occasions, etc. Rust affects the safety of use and has a short service life. The production of ladders facilitates people to work in different areas. [0003] The ladders that are practical in rural a...

[0002] Ladders are also called climbing ladders, a tool for daily life. The tool consists of two long thick poles as sides, and a horizontal bar suitable for climbing is crossed in the middle. It is used for climbing. Ladders are divided into lifting single ladders and lifting herringbone ladders. There are many kinds of ladders , as an auxiliary facility of the city inspection shaft in the city, the ladder material has been made of steel for a long time, but the traditional metal ladder is very easy to use in many harsh environmental conditions, such as manholes, tunnels, chemical companies, rainy and humid occasions, etc. Corrosion affects the safety of use and the service life is short. Through the production of ladders, it is convenient for people to work in different areas

[0003] The ladders that are practical in rural areas are basically installed with multiple connecting rods between two pillars to facilitate people to climb up step by step. Wire installation and connection, however, the utility pole is a cylindrical structure, when the ladder leans against the side wall of the utility pole, it is easy to cause the ladder to slide or tilt, causing casualties
