Embodiment Construction

[0012] The structure of the roller changing trolley in the degreasing section of the continuous galvanizing and annealing line involved in the present invention is as follows: figure 1 shown. Brush rolls and support rolls need to be replaced and repaired after working for a long time in the degreasing section of the galvanizing and annealing line. Due to the relationship between structure and assembly, manual hoisting is not easy to replace, so the roll changing trolley was designed and invented.

[0013] The roller changing trolley of the present invention is mainly composed of the following parts: roller bearing seat positioning chuck (1), roller traction trolley (2), traction motor, motor drive traction mechanism (3), motor oil supply drag chain (4), transmission Chain fixing mechanism (5), roller support frame (6), connecting rod elevating mechanism (7), rocking arm (71), two force bar (72), support frame (8), support block (9), support bar ( 10), electric control box bra...

Abstract

The invention provides a roller-replacing trolley. According to the invention, a roller comprises a shaft head and a roller notch; the roller-replacing trolley comprises a roller traction trolley, a traction motor, a motor transmission traction mechanism, a connection rod lifting mechanism, a rocker arm, a two-force rod, a support frame, a support block, a support rod, an electric control cabinetsupport, an electric control cabinet, a hydraulic pump station, a lifting guiding wheel, a walking transmission motor, a transmission shaft, a hydraulic cylinder, a wheel, a guiding rail, a roller-replacing sphere top hydraulic cylinder, a shaking hand wheel, a roller clamping plate, a positioning pin, a synchronizing shaft, a trailer wagon headstock and a sliding rail. The roller-replacing trolley provided by the invention brings great convenience for continuous zinc coating and the replacement of the roller in a degreasing section of an annealing line, the time for replacing the roller is reduced, the labor intensity of workers is lightened, and the production cost is reduced for a production line. The roller-replacing trolley is simple to operate, safe and reliable, shows humanity management of mechatronics and is inevitable equipment for a strip steel production line.

Description

technical field [0001] The invention relates to a roller changing trolley structure, which belongs to the application field of hydraulic pressure and machinery. Background technique [0002] The rollers are cylindrical parts and are divided into driving rollers and driven rollers. It is widely used in various transmission and conveying systems such as rotary screen printing machines, digital printers, mining conveying equipment, papermaking and packaging machinery. It is usually made of seamless steel pipes, and depending on the needs of different processes, materials such as aluminum alloy 6061T5, 304L / 316L stainless steel, 2205 duplex stainless steel, cast steel, and solid forged alloy steel core are also used. After the roller is formed, due to the needs of anti-rust, anti-corrosion, wear-resistant and support, surface treatment or coating such as painting, galvanizing, TEFLON spraying, rubber coating, chrome plating, ceramic spraying and oxidation are also required. ...
