Problems solved by technology

With this fixing method, the hanging ladder shakes severely and is prone to slipping. Although the hanging ladder rarely falls off, the shaking hanging ladder increases the difficulty of the operation and the fear in the operator's heart.
[0003] Since the lower end of the hanging ladder is directly lapped on the cable, it is difficult for the operator to fix it by hand, and setting a general hook at the lower end of the hanging ladder does not work

Embodiment Construction

[0027] Combine below Figure 1-Figure 5 Specific embodiments of the present invention are described in detail:

[0028] The present invention includes a ladder body 1, the ladder body 1 includes vertical bars I11 on both sides and a crossbeam 12 between the vertical bars I11, a hook I13 is provided at the front end of the ladder body 1, and a hook I13 is provided between the two A vertical rod II14 is arranged between the vertical rods I11, and a slideway 141 is arranged inside the vertical rod II14, and the bottom surface of the slideway 141 is open. The fixing method of the vertical bar II14 is preferably as follows: a slot 121 is provided in the middle of the beam 12, and the vertical bar II14 just fits into the slot 121, and then fixed by bolts or welding. Since the upper end of the hanging ladder body 1 may be fixed on different objects when it is fixed, such as a cable or a cross arm, but the front end of the current hanging ladder is only fixed with a hook, and the hoo...

Abstract

The invention relates to a three-point-fixed type hanging ladder for distribution network maintenance. The three-point-fixed type hanging ladder comprises a hanging ladder body and is characterized in that a vertical rod II is arranged between two vertical rods I, and a slideway is arranged in the vertical rod II; a slider, a chain, a chain wheel I and a chain wheel II are arranged in the slideway, and a hook II is arranged on the slider; a groove is formed in the front end of the hook II, a retaining plate is vertically arranged in the groove, the bottom of the retaining plate is hinged to the front end of the groove, and a torsional spring is arranged at the hinged part; a cavity is arranged in the slider, a sphere in the cavity is connected with one end of the torsional spring, and the other end of the torsional spring is connected with one end of the cavity; one end of the sphere is connected with a pull rope, and the other end of the pull rope is connected with the front end of the retaining plate; one end of a chain penetrate the cavity to be connected with the sphere, and the other end of the chain is connected with the slider; a rocker connecting end is arranged on the chain wheel I, and a rocker is connected with the rocker connecting end in a matched manner. The three-point-fixed type hanging ladder has the advantages that shaking and sliding of the hanging ladder are reduced to the maximum extent, and a stable, firm and safe operation platform is provided for operators.

Description

technical field [0001] The invention relates to a three-point fixed distribution network maintenance hanging ladder. Background technique [0002] The hanging ladder is a commonly used tool in the maintenance of the distribution network. The current hanging ladder is equipped with a hook at the front end of the hanging ladder body, which is used to hang on the cross arm of the tower pole or the cable, and the lower end of the hanging ladder body is directly connected to the line. . With this fixing method, the hanging ladder shakes severely and is prone to slipping. Although the hanging ladder rarely falls off, the shaking hanging ladder increases the difficulty of the operation and the fear in the hearts of the operators. [0003] Because the lower end of the hanging ladder is directly lapped on the cable, it is difficult for the operator to fix it by hand, and it is also ineffective to arrange a general hook at the lower end of the hanging ladder. Therefore, designing a ...
