Embodiment 1

[0031] See Figure 1-5 , A power insulated ladder, comprising a ladder body, the ladder body comprising two vertical rods 1 and a cross rod 2 connected between the two vertical rods 1, the top ends of the two vertical rods 1 are hinged to the connecting block 3, The outer edge of the vertical rod 1 is provided with a horizontal rotating shaft, and the connecting block 3 can be folded upward 90° around the horizontal rotating shaft. The two vertical rods 1 and the connecting block 3 respectively penetrate through the pullable support rod 4, and the support rod 4 The lower end is provided with a limit block, and the position is fixed when the support rod 4 is pulled to the uppermost end of the vertical rod 1. The two support rods 4 are crossed with pedals 5 on the inner sides, and the ends of the pedals 5 are close to the center line of the two vertical rods 1 , So that the insulation ladder does not cross when it is folded (see image 3 with Figure 4 ), the pedal 5 includes a p...

Embodiment 2

[0036] See Image 6 The structure of the power insulation ladder of this embodiment is basically the same as that of the power insulation ladder of embodiment 1, and the similarities will not be repeated. Some differences are: the edge of the pedal 5 is provided with anti-skid protrusions 10, and the support rod 4 is provided with The non-slip protrusion 10 is matched with a depression.

[0037] The surfaces of the vertical rods, cross rods, connecting blocks, support rods, and pedals are all coated with insulating paint, and the insulating paint is made of the following parts by weight: 100 parts of phenyltrichlorosilane and 33 parts of epoxy resin , 105 parts of organic solvent, 35 parts of polyamide resin, 2 parts of curing agent, 12 parts of film forming agent, 0.6 parts of leveling agent, 1.5 parts of dispersant, 6.5 parts of epoxy soybean oil and 9 parts of mica powder.

[0038] The organic solvent is ethyl acetate, the curing agent is benzoyl peroxide, the film-forming agent...

Embodiment 3

[0040] The structure of the power insulation ladder of this embodiment is basically the same as that of the embodiment 2, and the similarities are not repeated. Some differences are: the vertical bars, cross bars, connecting blocks, support bars, and pedals are all coated with insulation. Paint, the insulating paint is made of the following raw materials in parts by weight: 100 parts by weight of phenyltrichlorosilane, 35 parts of epoxy resin, 110 parts of organic solvent, 36 parts of polyamide resin, 2.5 parts of curing agent, 14 parts of film forming agent Parts, 0.8 parts of leveling agent, 1.6 parts of dispersant, 7 parts of epoxy soybean oil and 10 parts of mica powder.

[0041] The organic solvent is toluene, the curing agent is tert-butyl peroxybenzoate, the film forming agent is acrylic resin, the leveling agent is polydimethylsiloxane, and the dispersant is vinyl. Bistearylamide, the particle size of the mica powder is 1000 mesh.

Abstract

The invention relates to an insulated ladder, in particular to an electric insulated ladder. The electric insulated ladder comprises a ladder body. The ladder body comprises two vertical rods and transverse rods connected between the two vertical rods. Connecting blocks are hinged to the top ends of the two vertical rods correspondingly. Supporting rods capable of being pulled penetrate through the two vertical rods and the connecting blocks correspondingly. Limiting blocks are arranged at the lower ends of the supporting rods. Pedals are oppositely arranged on the inner sides of the two supporting rods in a staggered mode, the tail ends of the pedals are close to the median line of the two vertical rods, and the pedals can be folded upwards by 90 degrees. Carrying discs are hinged to the tail ends of the connecting blocks. Grooves are formed in the outer sides of the lower ends of the vertical rods. Connecting rods are rotatably connected in the grooves. Universal wheels are arranged at the tail ends of the connecting rods. Each transverse rod is formed by sleeving of two telescopic rods. The vertical rods, the transverse rods, the connecting blocks, the supporting rods and the pedals are all coated with insulated paint. The insulated ladder is simple in structure, low in manufacturing cost, diverse in function, adjustable in height and width, convenient to use and safe in operation.

Description

Technical field [0001] The invention relates to an insulation ladder, in particular to a power insulation ladder. Background technique [0002] The electric insulation ladder is a special climbing tool for the electric power industry, which guarantees the life safety of construction workers to the greatest extent. At present, many electric power construction environments in the electric power department are uncertain, and the existing electric insulation ladders are relatively fixed in length, heavy, and inconvenient to use. As a result, electric power construction is more difficult, construction time is prolonged, and safety is low. [0003] The utility model patent of the authorized announcement number CN205503002U discloses an insulated ladder, including a ladder body, the ladder body includes two vertical rods and a horizontal rod connected between the two vertical rods, and the ladder body is wound parallel to the horizontal rod The axis rotation is equipped with a guardrail....
