Embodiment 1

[0022] Embodiment 1: as figure 1 , 2 , 3, 4, 5, and 6, a ladder with adjustable hooks, including two vertical poles 1 on both sides and several horizontal pedals 2, the poles and the pedals are fixedly connected by bolts, and the poles are close to the pedals The inner side of the pole is provided with a groove 3, the outer side of the pole is provided with a slider 4 sliding along the groove, the inside of the slider is provided with a sleeve 5, the slider is connected with the hook 6 through the sleeve, and the hook and the sleeve are connected by threads . The cross section of the slider is "concave" shape, the inside of the slider is hollow, forming a sliding chamber 7, and two openings 8 that run through the entire side and are parallel to the bottom are respectively provided on the three sides of the slider. The sleeve is a hollow cylinder with a circular cross-section. The sleeve is tangent to the inner wall of the sliding cavity and slides along the sliding cavity. T...

Embodiment 2

[0024] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as Figure 7 , 8 As shown, the inner side of the hook is provided with a plastic mat 11, and the surface of the plastic mat is jagged. The plastic mat is located at the place where the hook contacts with the suspension support 12, and is jagged, which increases the contact area and friction between the hook and the suspension support, so that even if the ladder shakes, it is not easy to slip off from the foot buckle.

Abstract

The invention relates to a climbing operation tool, in particular to a hook-adjustable crawling ladder. The hook-adjustable crawling ladder comprises two vertical upright rods on the two sides and a plurality of horizontal pedals. The upright rods and the pedals are fixedly connected through bolts, and grooves are formed in the inner sides, close to the pedals, of the upright rods. Sliding blockssliding along the grooves are arranged on the outer sides of the upright rods in a sleeving mode, and sleeves are arranged in the sliding blocks. The sliding blocks are connected with hooks through the sleeves, and the hooks are connected with the sleeves through threads. According to the hook-adjustable crawling ladder, the lengths and directions of the hooks can be adjusted, the structure is simple, the price is low, application is wide, the ladder can be effectively prevented from sliding down in the hanging process, and the operation safety is enhanced accordingly.

Description

technical field [0001] The invention relates to a working tool for climbing heights, in particular to a climbing ladder with adjustable hooks. Background technique [0002] As we all know, we use a lot of ladders in electrical, railway, building construction and other fields. Now most of them use scaffolding or hydraulic lifting construction platforms. However, these equipment are expensive and the erection process is cumbersome. It can only be used under certain environmental conditions such as traffic and electricity, which brings inconvenience to construction and reduces work efficiency. Therefore, ordinary ladders must be used for many climbing operations. Power system workers often need to climb to high places on utility poles for maintenance and installation of electric wires. They usually climb on the foot buckle of the utility pole with their feet. , and the hands and feet are easy to slip in bad weather, making the staff in danger of falling. [0003] At present, ...
