Problems solved by technology

To solve this problem, the current method is mostly to take turns. Workers come down when encountering parts that they don’t understand and replace them with someone who may understand. This kind of rotation is quite inefficient for maintenance operations.
Another problem is that electric power maintenance often requires electrified operation. If there is a slight error in the operation, it is easy to cause accidents such as electric shock and short circuit. Maintenance workers will always make mistakes and be inattentive. Only one person can operate on the maintenance ladder, and the lack of real-time supervision and review of maintenance personnel may easily lead to accidents
To sum up, there is a lack of a power maintenance ladder in the prior art that can provide more convenient technical support for power maintenance that requires multiple people to participate at the same time, and can also realize real-time supervision and review of maintenance personnel.

specific Embodiment 1

[0020] combined with Figures 1 to 5 , an electric maintenance ladder, which includes two support legs 1 and several beams 2 arranged between the support legs 1; it is characterized in that: it also includes a first observation device 7, a first bushing 3 and a connecting rod 4; The first observation device 7 includes an upper observation port 5 and a lower observation port 8, and the upper and lower observation ports are connected by a light guide; the upper observation port 5 is provided with an upper mirror body 9, and the lower observation port 8 is provided with a lower mirror body 10 , the upper mirror body 9 is used to reflect the scene in front of the upper observation port 5 to the lower mirror body 10; the first observation device 7 is plugged into the first sleeve 3, and the first sleeve 3 is connected to the support through the connecting rod 4 The legs 1 are connected; the first sleeve 3 includes a metal outer layer 301 and a rubber lining 302, the first sleeve 3 ...

specific Embodiment 2

[0022] On the basis of embodiment one, further combined with the attached Figure 6 , on the basis of the structure of the embodiment, the first sleeve 3 is changed to a clamp structure, that is, the metal outer layer 301 is an opening structure, and the opening extends out of the tightness adjustment port 304, and the elastic adjustment port 304 is connected to a useful The screw used to adjust the tightness of the clamp.

specific Embodiment 3

[0023] On the basis of embodiment two, further combined with the attached Figure 7 , the electric maintenance ladder also includes a second observation device 12 with the same structure as the first observation device 7, and the second observation device 12 is connected to the other support leg of the electric maintenance ladder through a second bushing 13 and a second connecting rod 1, that is, the other supporting leg 1 besides the first viewing device already installed.

[0024] In the above three embodiments, the light guide tube is a hollow tube, and its structure is the same as that of the tube connecting the two mirror bodies in the periscope, but since it is not used in water, it does not need to be sealed.

[0025] Except above above embodiment, the present invention can also make following improvements, 1, add a pair of handles 16 at the lower viewing port of each viewing device, so that the workers below can hold it better when rotating and lifting the viewing devi...

Abstract

The invention provides a power maintenance ladder which can provide more convenient technical support for power maintenance in which multiple persons participate at the same time, and with the power maintenance ladder, the maintenance personnel can be supervised and reexamined in real time. The power maintenance ladder comprises two supporting legs (1) and a plurality of beams (2) and is characterized by further comprising a first observation device (7), a first sleeve (3) and connecting rods (4), the first observation device (7) comprises an upper observation opening (5) and a lower observation opening (8), and the upper observation opening and the lower observation opening are connected through a light pipe; the scene in front of the upper observation opening (5) is reflected to a lower mirror body (10) through an upper mirror body (10); the first observation device (7) is inserted into the first sleeve (3) in a connected mode, and the first sleeve (3) is connected with the supporting legs (1) through the connecting rods (4); the first sleeve (3) keeps the position of the light pipe through elasticity of a rubber liner (302), and the connecting rods (4) are telescopic rods and rotationally connected with the supporting legs (1).

Description

technical field [0001] The invention relates to a tool for electric power maintenance, in particular to an electric power maintenance ladder. Background technique [0002] At present, electricity has become an indispensable energy source in people's life. In order to ensure a stable supply of electricity, a large number of electric workers and maintenance tools are required for support. The power maintenance ladder is the most commonly used tool, and most of the power maintenance ladders in the prior art are the most common ladders, and at most, some insulation treatments have been done. With the vigorous promotion of smart grid technology, power maintenance often involves multiple fields. There are complex circuits in the power cabinet, involving many fields such as machinery, electric control, and software debugging. This kind of maintenance often requires experts from multiple fields. Workers participate simultaneously. The problem is that many power cabinets are suspe...
