Description

Technical Field

[0001] The invention relates to the field of hot-dip galvanizing devices, and in particular to a hot-dip galvanizing zinc pot cover linked lifting protective door equipment. Background Art

[0002] In the galvanizing industry, a large amount of industrial waste gas is often generated, which pollutes the workshop production environment and endangers the physical and mental health of production personnel. Emission into the atmosphere will lead to environmental deterioration. In particular, some highly corrosive waste gases not only endanger human health but also corrode the machinery and equipment in the workshop, which is extremely harmful. According to statistics, 40% of the annual zinc production in the world is used for hot-dip galvanizing, and hot-dip galvanizing is also a traditional heavily polluting industry, generating a large amount of waste gas and dust. With the development of society, the improvement of production efficiency and the improvement of environmental protection requirements, the requirements for the hot-dip galvanizing industry are also gradually increasing. Therefore, the establishment of a clean hot-dip galvanizing environment with environmental protection, energy saving and high efficiency has become an inevitable trend in the development of the industry.

[0003] Considering the problem of workpiece entry and exit, the previous zinc pot cover only surrounded the top and three sides, leaving a way for material entry and exit, and set an overall air supply and exhaust device on the top of the workshop to collect corrosive waste gas, or just make a four-side ventilated gas collecting hood on the upper part of the zinc pot. Although such waste gas collection device can absorb a certain amount of waste gas, it cannot completely solve the problem of waste gas diffusion in the galvanizing workshop. Waste gas and dust will still diffuse out from the galvanizing entrance and exit doors, and the amount of waste gas absorbed is limited, and it is impossible to improve the working environment of the direct operators in the first place. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a hot-dip galvanizing zinc pot cover linked lifting protective door equipment with a simple structure, which can reduce the unorganized emission of waste gas and dust during the hot-dip galvanizing process, improve the collection efficiency of waste gas and dust, and significantly improve the working environment of hot-dip galvanizing.

[0005] In order to solve the above technical problems, the present invention provides a hot-dip galvanized zinc pot cover linked lifting protective door equipment, comprising two columns, a truss is arranged between the columns, a protective door is arranged at the bottom end of the truss, a lifting mechanism for controlling the truss is arranged on the column, and a closing and opening mechanism for controlling the protective door is arranged on the truss; the closing and opening mechanism comprises a motor, a reducer, and a reel arranged in sequence, a first coupling and a bearing are arranged in sequence between the reducer and the reel, a hanging bag is arranged on the reel, and a second coupling is arranged between two adjacent reels.

[0006] Furthermore, the first coupling is a plum blossom coupling.

[0007] Furthermore, the second coupling is a cross universal joint coupling.

[0008] Furthermore, the lifting mechanism controls the movement of the truss by chain transmission, and a counterweight mechanism is arranged on the lifting mechanism, the counterweight mechanism includes a counterweight block, and the counterweight block is connected to the lifting mechanism by a steel wire rope, and a lifting mechanism is arranged between the steel wire rope and the counterweight block.

[0009] Furthermore, a guiding walking mechanism is arranged on the counterweight block.

[0010] Furthermore, the mass of the counterweight block is 100 kg heavier than the total mass of the truss and the protective door.

[0011] Furthermore, a shock-absorbing pad is provided at the bottom end of the protective door near the counterweight block, and the shock-absorbing pad is made of rubber.

[0012] Furthermore, the structure of the protective door is a multi-layer assembly, and each layer of the protective doors is connected by a pin shaft.

[0013] Furthermore, the protective panel of the protective door is made of high temperature resistant non-metallic material.

[0014] Furthermore, a photoelectric switch is provided on the column.

[0015] The beneficial effects of the present invention are as follows: 1. The device utilizes a lifting mechanism to drive the truss, and the closing and opening mechanism on the truss drives the protective door in such a way that both the vertical position of the truss and the position of the protective door can be adjusted. When plastering, the protective door is driven by a motor, and the panel is lifted upward, making it convenient for workers to enter and exit the zinc pot cover for plastering; when the workpiece is galvanized and fed in and out, the protective door is driven by a motor to lift the panel upward to the top, and during the lifting process, the truss simultaneously falls to the ground; after the feeding and unloading are completed, the protective door lowers the panel, and the truss rises at the same time.

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0020] Reference Figure 1 to Figure 2 As shown, an embodiment of a hot-dip galvanized zinc pot cover linked lifting protection door 2 equipment of the present invention comprises two columns 1, a truss 4 is arranged between the columns 1, a protection door 2 is arranged at the bottom end of the truss 4, a lifting mechanism 3 for controlling the truss 4 is arranged on the column 1, and a closing and opening mechanism 5 for controlling the protection door 2 is arranged on the truss 4; the closing and opening mechanism 5 comprises a motor 51, a reducer 52, and a reel 55 which are arranged in sequence, a first coupling 53 and a bearing 54 are arranged in sequence between the reducer 52 and the reel 55, a plurality of reels 56 are arranged on the reel 55, a sling is arranged on the reel 56, and a second coupling 57 is arranged between two adjacent reels 55.

[0021] When in use, a guide rail is provided on the column 1 to limit the position of the protective door 2 and the truss 4 to prevent the protective door 2 from deviating from the original running track. The truss 4 lifting mechanism 3 is used to control the lifting of the truss 4. When plastering, the protective door 2 is driven by the motor 51, and the panel is lifted upward by 2 to 2.5 meters, which is convenient for workers to enter and exit the zinc pot cover for plastering; when the workpiece is galvanized and fed in and out, the protective door 2 is driven by the motor 51 to lift the panel upward to the top. During the lifting process, the truss 4 falls to the ground at the same time; after the feeding and unloading are completed, the protective door 2 puts down the panel, and the truss 4 rises at the same time. The way in which the motor 51 drives the protective door 2 is: start the motor 51, the motor 51 drives the reducer 52, the reducer 52 drives the reel 55 to rotate through the first coupling 53 and the bearing 54, the rotation of the reel 55 drives the reel 56 to rotate, and the rotation of the reel 56 retracts the protective door 2 into the reel 56. If the protective door 2 is to be put down, the motor 51 can be rotated in the opposite direction.

[0022] The first coupling 53 adopts a plum blossom coupling, which has a simple structure, no need for lubrication, convenient maintenance, easy inspection, maintenance-free, and can run continuously for a long time. The high-strength polyurethane elastic element is wear-resistant and oil-resistant, has a large load-bearing capacity, a long service life, and is safe and reliable. It works stably and reliably, and has good vibration reduction, buffering and electrical insulation properties. It has large axial, radial and angular compensation capabilities. It has a simple structure, small radial size, light weight, and small moment of inertia, and is suitable for medium and high speed occasions.

[0023] The second coupling 57 adopts a cross universal joint coupling, which has a large angle compensation capability, a compact and reasonable structure, and a large load capacity. Compared with other types of couplings with the same rotation diameter, it transmits a larger torque, and has a more advantageous matching range for mechanical equipment with limited rotation diameter, stable transportation, low noise, and convenient assembly and disassembly maintenance.

[0024] The lifting mechanism 3 controls the movement of the truss 4 by chain transmission. The lifting mechanism 3 is provided with a counterweight mechanism 6, which includes a counterweight block 61. The counterweight block 61 is connected to the lifting mechanism 3 by a steel wire rope 64. A hoisting mechanism 63 is provided between the steel wire rope 64 and the counterweight block 61. The mass of the counterweight block 61 is 100 kg heavier than the total mass of the truss 4 and the protective door 2. In case of an accident, the truss 4 and the protective door 2 will rise as a whole until the counterweight block 61 touches the ground instead of falling to injure people or the zinc pot. In addition, a shock-absorbing pad 7 is provided at the bottom end of the column 1 near the protective door 2. The shock-absorbing pad 7 is made of rubber to prevent the counterweight block 61 from falling rapidly and reduce vibration and noise.

[0025] The protection panel of the protection door 2 is made of high temperature resistant non-metallic material, such as Teflon plastic.
