[0029] see Figure 1-3 , an insulating stool, including a high stool and a low stool, the high stool includes four vertical long legs 1, two rear long legs 1 lower end rear side walls are respectively provided with universal wheels 11, four vertical long legs A high pedal 2 is fixed between the tops of the legs 1, the front edge of the high pedal 2 extends beyond the edge of the front long leg, and a reinforcing cross bar 3 is arranged between the front long leg and the rear long leg, A chute 4 is respectively arranged on the two reinforced cross bars, and the first support rod 5 is slidably connected in the two chute, and the two ends of the first support rod 5 are respectively provided with sliders matching the two chute 4, and the sliders The first support bar 5 is driven to slide in the chute 4, and the low stool includes two vertical short legs 6, and a low pedal is fixed between the tops of the two vertical short legs 6 and the first support bar 5 7. The four vertical l...

Embodiment 2

[0035] see Figure 4 , the structure of the insulating stool of the embodiment of the present invention is basically the same as that of the embodiment 1, and the similarities will not be repeated. Some differences are: any auxiliary leg is a hollow structure, and a second support that can be drawn is set inside the auxiliary leg 8 Rod 12, the lower end of the second support rod 12 is provided with a limit block, when the second support rod 12 is pulled to the uppermost end of the auxiliary leg 8, the position is fixed, and the top of the second support rod 12 is provided with a tray 13.

[0036] The surfaces of the long legs, high pedals, short legs, low pedals, auxiliary legs and heightened pedals are all coated with insulating varnish, and the insulating varnish is made of the following raw materials in parts by weight: 43 parts of epoxy resin, 10.5 parts of phthalic anhydride, 32 parts of polyamide resin, 102 parts of pentaerythritol, 12 parts of styrene resin, 11 parts of...

Embodiment 3

[0041] The structure of the insulating stool of the embodiment of the present invention is the same as that of Embodiment 2, and the similarities will not be repeated. Some differences are:

[0042] The surfaces of the long legs, high pedals, short legs, low pedals, auxiliary legs and heightened pedals are all coated with insulating varnish, and the insulating varnish is made of the following raw materials in parts by weight: 45 parts of epoxy resin, 11 parts of phthalic anhydride, 33 parts of polyamide resin, 105 parts of pentaerythritol, 15 parts of styrene resin, 12 parts of acrylic resin, 3 parts of curing agent, 0.8 parts of leveling agent, 1.5 parts of dispersing agent , 7.5 parts of coupling agent and 9 parts of mica powder.

[0043] The curing agent is tert-butyl peroxybenzoate, the leveling agent is polydimethylsiloxane, the dispersant is vinylbisstearamide, and the coupling agent is γ-methacrylic acid Acyloxypropyltrimethoxysilane.

Abstract

The invention relates to a working tool for aerial work, in particular to an insulation stool. The insulation stool comprises a high stool and a low stool, wherein the high stool comprises four vertical long support legs, universal wheels are arranged on the rear side walls of the lower ends of the two rear long support legs respectively, a long-legged pedal is fixed among top ends of the four vertical long support legs, reinforcing cross bars are arranged between the front long support legs and the rear long support legs, slide grooves are formed in the two reinforcing cross bars, and a first support rod is glidingly connected in the two slide grooves; the low stool comprises two vertical short support legs, and a short-legged pedal is fixed among top ends of the two vertical short support legs and the first support rod; the four vertical long support legs are of a hollow structure, through holes are formed in positions, corresponding to the four vertical long support legs, of the long-legged pedal, drawable auxiliary support legs are arranged in the four vertical long support legs respectively, upper ends of the four auxiliary support legs penetrate the through holes, limit blocks are arranged at lower ends of the four auxiliary support legs, and a heightened pedal is fixed among top ends of the four auxiliary support legs. The insulation stool occupies small space and is safe to operate, and height of the insulation stool is convenient to adjust.

Description

technical field [0001] The invention relates to a work tool for climbing a height, in particular to an insulating stool. Background technique [0002] The insulating stool is a common tool for climbing work in the electric power field. The existing insulating stools mostly use double-layer insulating stools, which are bulky, occupy a large space, are heavy, and are not easy to move. [0003] The utility model patent of authorized notification number CN205410488U discloses a mobile high and low insulating stool, which includes a stool body composed of a high stool and a low board. There are two parallel tie rods perpendicular to the connecting rod between the lower parts of the two legs and the stool surface. The two pull rods extend out of the upper end of the stool surface. The upper ends of the two pull rods are provided with arc-shaped handles, and the arc-shaped handles are covered with rubber sleeves; Friction wheels are arranged on the outer sides of the lower parts o...
