Novel welding device special for color steel roofing photovoltaic support and operation process

Abstract

The invention discloses a novel welding device special for a color steel roofing photovoltaic support and an operation process. The novel welding device special for the color steel roofing photovoltaic support comprises a welding gun and a welding power supply. A pressure adjusting knob, a linear bearing and a welding switch are arranged on the welding gun; a chuck stroke column is arranged on the linear bearing; a welding bolt chuck is arranged on the lower end of the chuck stroke column; a welding bolt is arranged on the welding bolt chuck; a special welding bot is placed in the welding bolt; and the welding power supply comprises a transformer, a charging rectifier bridge, a charging silicon controlled rectifier, an energy storage capacitor, a discharging silicon controlled rectifier, a ground lead and a grounding clamp. The operation process of the novel welding device special for the color steel roofing photovoltaic support comprises the steps of switching on the power supply, clamping the welding bolt, welding, and carrying out preservative treatment on welding points. The welding device special for the color steel roofing photovoltaic support has the following characteristics that the photovoltaic support and color steel tiles are connected in a welding way, so that punching on a color steel roofing is avoided, a roofing waterproof effect is not damaged, the structure strength of the photovoltaic support is improved, and the used parts is less.

Description

technical field [0001] The invention relates to a new type of special welding equipment and an operation process for a photovoltaic support of a color steel tile roof, belonging to the field of solar photovoltaic power generation. Background technique [0002] In the photovoltaic industry, roof photovoltaic supports are divided into concrete flat roofs, glazed tile sloping roofs, and color steel tile roofs. Among them, color steel tile roof photovoltaic supports are divided into angle type, vertical seam type and trapezoidal bolts according to the connection method with color steel tiles. Fixed or strong adhesive type, the connection mode of the prior art is the corner chi type and the standing seam type, which are fixtures for producing corresponding cross-sectional shapes for the corrugated cross-sectional shapes of color steel tiles (see figure 1 , figure 2 , image 3 , Figure 4 ), the fixture is fastened on the corrugated board through the fastening bolts on the fix...

AI Technical Summary

Problems solved by technology

[0006] First, punching holes in the trapezoidal color steel tile roof will destroy the original waterproof effect of the roof. Even if waterproof adhesive strips are added or any waterproof adhesive is applied, the original waterproof effect will not be achieved. Under the action of load, earthquake load, ambient temperature and humidity, and oxygen in the air, the waterproof rubber strip or waterproof glue will crack and deform due to aging, resulting in rainwater penetration

[0007] Second, after the color steel tile is drilled, the section of the hole is exposed in the air. Even if the section of the hole is subjected to anti-corrosion treatment after drilling, the anti-corrosion layer of the section of the hole will be destroyed again due to the entry of bolts or rivets. will be corroded and rusted

[0008] Third, the fixture is connected to the color steel tile by punching holes and bolts or rivets, and the thickness of the existing color steel tile is between 0.25mm and 0.8mm, and the connection between the bolts or rivets and the color steel tile is too small due to the small contact section. As a result, the connection strength is insufficient, which can easily cause the fixture to loosen or even fall off

[0009] Fourth, the connection method of super glue bonding will cause loosening and falling off due to aging, cracking and deformation under the action of long-term wind load, snow load, earthquake load, ambient temperature and humidity, and oxygen in the air.

[0010] Fifth, the connection method of placing waterproof adhesive strips between the fixture and the trapezoidal color steel corrugated or brushing waterproof adhesive and then drilling holes and adding bolts or rivets or superglue bonding has complicated construction procedures and many parts used. Long construction time and high cost of raw materials

[0012] The above-mentioned color steel tile roof photovoltaic support and installation method are also due to the large wind load and earthquake load on the roof of multi-storey, especially high-rise buildings. In this case, the sliding of photovoltaic brackets and photovoltaic modules will cause personal and property losses. This risk must be avoided in the building photovoltaic industry
