Description

Technical Field

[0001] This utility model belongs to the field of steel grating processing technology, specifically relating to a rapid cooling device for steel grating after hot-dip galvanizing. Background Technology

[0002] Hot-dip galvanizing, also known as hot-dip zinc plating, is based on the metallurgical bonding between metals: when a steel grating is heated to a certain temperature and immersed in molten zinc (temperature about 440-460℃), the iron and zinc on the steel surface react chemically to form a composite coating consisting of a zinc-iron alloy layer and a zinc layer.

[0003] After hot-dip galvanizing, steel gratings need to be cooled. To improve efficiency, workers often stack multiple steel gratings together and put them into the galvanizing bath during the galvanizing process. However, during cooling, the stacked steel gratings form closed or semi-closed spaces, making it difficult for cold water to circulate fully and affecting the cooling effect between the steel gratings. Utility Model Content

[0004] The purpose of this invention is to provide a rapid cooling device for hot-dip galvanized steel grating, in order to solve the problem that existing cooling devices in the prior art tend to cause uneven cooling of steel grating.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rapid cooling device for hot-dip galvanized steel grating includes a frame. An auxiliary mechanism is provided inside the frame. The auxiliary mechanism includes a pad plate disposed inside the frame. Four L-shaped plates are fixedly connected to the end face of the pad plate. Four rectangular frames are fixedly connected to the end face of the frame. The four L-shaped plates are slidably connected to the four rectangular frames respectively. Protrusions are fixedly connected to the end face of the L-shaped plates. A motor is installed on the side wall of the frame. A round rod is fixedly connected to the output end of the motor. Two extrusion columns are fixedly connected to the arc surface of the round rod.

[0007] Preferably, a first spring is fixedly connected to one side of the rectangular frame, and the end of the first spring away from the rectangular frame is fixedly connected to the L-shaped plate.

[0008] Preferably, both sides of the frame are fixedly connected to fixed rails, the inner walls of the fixed rails are slidably connected to fixed plates, the surfaces of the two fixed plates are rotatably connected to rotating rods, and the ends of the two rotating rods that are close to each other are fixedly connected to adsorption covers.

[0009] Preferably, a connecting block is fixedly connected to the surface of one of the fixing plates, and a driving plate is fixedly connected to the arc surface of the round rod.

[0010] Preferably, a fixing block is fixedly connected to the side wall of one of the fixing plates, and a plug rod is slidably inserted into the end face of the fixing block. The inner wall of the fixing track is provided with a plurality of insertion holes that are adapted to the plug rod.

[0011] Preferably, a second spring is fixedly connected to the side of one of the fixing plates away from the fixing block, and a vertical block is fixedly connected to the end of the second spring away from the fixing block, the vertical block being fixedly connected to the inner wall of the fixing track.

[0012] Preferably, the cross-sectional shape of both the extrusion column and the drive plate is elliptical.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses the extrusion column to extrude the protrusion, and under the elastic force of the first spring, the pad plate can be made to shake back and forth, thereby causing the steel grating on the pad plate to shake. This facilitates the creation of gaps between multiple steel gratings, which in turn facilitates the flow of cooling water, improves the cooling effect on the steel grating, and enhances the uniformity of cooling.

[0015] 2. This utility model uses an adsorption hood to adsorb hydrogen generated during the cooling process of the rigid grid plate, thus minimizing the accumulation of hydrogen around the frame. With the help of the driving plate squeezing the fixed block, the adsorption hood can move back and forth while the rigid grid plate shakes, increasing the adsorption range of hydrogen.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 As shown, this utility model provides a rapid cooling device for hot-dip galvanized steel grating, including a frame 1. An auxiliary mechanism 2 is provided inside the frame 1. The auxiliary mechanism 2 includes a pad 201 disposed inside the frame 1. Four L-shaped plates 202 are fixedly connected to the end face of the pad 201. Four rectangular frames 203 are fixedly connected to the end face of the frame 1. The four L-shaped plates 202 are slidably connected to the four rectangular frames 203 respectively. A protrusion 204 is fixedly connected to the end face of the L-shaped plates 202. A motor 206 is installed on the side wall of the frame 1. The motor 206 is controlled to start and stop by an external power supply, which is a conventional method in this field and will not be described in detail here. A round rod 207 is fixedly connected to the output end of the motor 206. Two extrusion columns 208 are fixedly connected to the arc surface of the round rod 207. A first spring 205 is fixedly connected to one side of the rectangular frame 203. The end of the first spring 205 away from the rectangular frame 203 is fixedly connected to the L-shaped plate 202.

[0024] It should be noted that the frame 1 is filled with cooling water, the extrusion column 208 has an elliptical cross-section, the protrusion 204 has a triangular cross-section, and the protrusion 204 is in intermittent contact with the extrusion column 208. Under the action of the first spring 205, the pad 201 moves back and forth repeatedly.

[0025] In an optional embodiment: fixed rails 209 are fixedly connected to both sides of the frame 1, fixed plates 210 are slidably connected to the inner wall of the fixed rails 209, rotating rods 211 are rotatably connected to the surfaces of the two fixed plates 210, and adsorption covers 212 are fixedly connected to the ends of the two rotating rods 211 that are close to each other.

[0026] It should be noted that the adsorption hood 212 is connected to an external fan to adsorb the hydrogen gas generated during the cooling process of the steel grating, so as to avoid excessive accumulation of hydrogen gas around the frame 1.

[0027] In an optional embodiment: a connecting block 213 is fixedly connected to the surface of one of the fixing plates 210, and a driving plate 214 is fixedly connected to the arc surface of the round rod 207.

[0028] It should be noted that the cross-sectional shape of the drive plate 214 is elliptical, and the side of the connecting block 213 that is squeezed is inclined. The connecting block 213 and the drive plate 214 are in intermittent contact. Under the elastic force of the second spring 217, the adsorption cover 212 moves back and forth, thereby expanding the adsorption range.

[0029] In one optional embodiment: a fixing block 215 is fixedly connected to the side wall of one of the fixing plates 210, and a plug rod 216 is slidably inserted into the end face of the fixing block 215. The inner wall of the fixing track 209 is provided with a plurality of insertion holes that are adapted to the plug rod 216.

[0030] In an optional embodiment: a second spring 217 is fixedly connected to the side of one of the fixing plates 210 away from the fixing block 215, and a standing block 218 is fixedly connected to the end of the second spring 217 away from the fixing block 215, and the standing block 218 is fixedly connected to the inner wall of the fixing track 209.

[0031] It should be noted that when it is not necessary for the adsorption cover 212 to move back and forth with the shaking of the pad 201, the fixed plate 210 is moved so that the connecting block 213 and the drive plate 214 are not on the same straight line. At this time, the second spring 217 is in a deformed state. By inserting the plug 216 into the corresponding plug hole, the fixed plate 210 is stabilized.

[0032] The working principle of this utility model is as follows: During use, the operator uses a hoist to place multiple stacked steel gratings into the frame 1 for cooling. The steel gratings will contact the pad 201. Then, the motor 206 is started through the external power control terminal, which drives the round rod 207 to rotate. The extrusion column 208 will then rotate, extruding the protrusion 204. The protrusion 204 will slide under pressure, that is, the L-shaped plate 202 will slide along the inside of the rectangular frame 203. The first spring 205 is in a deformed state. As the extrusion column 208 rotates continuously and the first spring 205 rebounds continuously, the pad 201 will move back and forth, which will make the steel gratings shake, thus facilitating the creation of gaps between multiple steel gratings. The gap facilitates the flow of cooling water and improves the cooling effect. When the rotating rod 211 rotates, the driving plate 214 also rotates and squeezes the connecting block 213. The connecting block 213 moves when squeezed, and the second spring 217 is in a deformed state. The side of the connecting block 213 that is squeezed is inclined, and the driving plate 214 is elliptical in shape. The connecting block 213 and the driving plate 214 are in intermittent contact, that is, the second spring 217 repeatedly rebounds, causing the fixed plate 210 to move back and forth repeatedly, so as to achieve the effect of moving the adsorption cover 212 back and forth. By connecting the adsorption cover 212 to an external fan, the hydrogen gas generated during the cooling process of the steel grating can be sucked away, and the situation of hydrogen gas accumulating around the frame 1 can be avoided.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
