Protective device for hot galvanizing process

Abstract

The invention relates to the technical field of hot galvanizing equipment, and discloses a protective device for a hot galvanizing process. The protective device comprises a front moving frame and a rear moving frame, a protective shell is mounted between two sides of the moving frames, a fixed door is mounted at the right side of the upper end of the front moving frame, a movable door is arranged at the left side of the fixed door, a sliding block is mounted at the upper end of the movable door, and a lead screw is mounted in the middle of the sliding block through a threaded structure; and a movable plate is installed at the bottom of the movable door, rotating columns are installed at the two sides of the lower end of the movable plate, rotating wheels are installed at the lower ends of the rotating columns, a fixed guide rail is installed at the upper end of the front moving frame through a fixed column, the fixed guide rail is arranged between the two rotating wheels and makes contact with the rotating wheels, and a driving rod is installed at the upper ends in the moving frames. According to the protective device, stable movement of the movable door is achieved, non-manual movement is achieved under cooperation of the sliding block and the lead screw, and therefore the protection effect is further improved; and meanwhile, a supporting rod and a threaded area are arranged, adjustment of the vertical positions of a supporting wheel is achieved, and the maneuverability of the protective device is further improved.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing equipment, in particular to a protective device for a hot-dip galvanizing process. Background technique [0002] Hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing: it is an effective metal anti-corrosion method, which is mainly used for metal structure facilities in various industries. In the process, the zinc layer is attached to the surface of the steel member, so as to achieve the purpose of anticorrosion. [0003] With the development of production technology, the production speed is getting faster and faster, and the potential danger to operators is also increasing. During the hot-dip galvanizing production process, the temperature of the zinc liquid is relatively high, and high-temperature splashing of the zinc liquid is easy to occur, so , must be equipped with good protection settings. [0004] In the prior art, slide rails are set on the frame of...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, slide rails are set on the frame of the hot-dip galvanized tank body. In the early stage of work, the protective warehouse will move to the top of the hot-dip galvanized tank body through the slide rails, thereby isolating the hot-dip galvanized tank body from the outside world. It can start working and then play a protective role, but the protective box is bulky and moves slowly, which reduces work efficiency

[0005] The prior art discloses a protective device for the hot-dip galvanizing process, which includes a hot-dip galvanizing tank body, which is placed horizontally, and the top of the hot-dip galvanizing tank body is provided with a strip-shaped slot along the frame, and the strip-shaped slot There are partitions inserted inside, and the partitions are all set vertically. The upper ends of the partitions are all equipped with limit blocks. The limit blocks are arranged on the outer wall of the partitions. The telescopic rod is arranged vertically, the lower end of the electric telescopic rod is fixedly connected with the base, the base is fixedly connected with the outer wall of the hot-dip galvanized tank, and the upper part of the long slot is equipped with a baffle, and the baffle is hinged at the top of the hot-dip galvanized tank On the frame, although the device has realized the protective effect on the hot-dip galvanizing process to a certain extent, it still needs to be operated manually, and the movement stability of the protective hatch is still not high, so further improvement is still needed
