Description

Technical Field

[0001] This utility model relates to the field of steel floor processing technology, and in particular to a fly ash cement-based steel floor surface spraying device. Background Technology

[0002] In the fields of building decoration and industrial flooring, steel floors are widely used due to their high strength and wear resistance. Fly ash cement-based materials, as a composite coating that combines the utilization of industrial waste with high performance requirements, have their surface spraying process directly affecting the corrosion resistance, aesthetics and service life of steel floors.

[0003] In industrial production scenarios involving the spraying of fly ash cement-based composite coatings onto steel floor surfaces, existing spraying equipment typically employs a fixed installation structure for its spray units. This structure results in a lack of dynamic adaptation mechanisms for the nozzle's spray angle adjustment. When spraying steel floors of varying widths, the fixed spray unit's nozzle array struggles to effectively coat panels of different widths. Therefore, a fly ash cement-based steel floor surface spraying device needs to be designed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 5 As shown, this utility model embodiment provides a fly ash cement-based steel floor surface spraying device, which mainly includes a conveying component 1 and a covering component 2;

[0030] The conveying assembly 1 includes a support frame 11 and a power-driven conveyor belt 12 on the support frame 11 for conveying fly ash cement-based steel floor.

[0031] The cover assembly 2 includes a spray cover 21 mounted on a support frame 11 in a sleeved state, and a feeding unit mounted on the spray cover 21. The feeding unit includes a guide pipe 22 connected to the spray cover 21 for conveying composite coating. The guide pipe 22 is adapted to be connected to an external feeding device. One end of the guide pipe 22 extends into the spray cover 21, and a storage pipe 23 is connected to one end of the guide pipe 22. Three sets of pipe fittings 231 are threaded at equal intervals on the storage pipe 23.

[0032] Furthermore, each of the three sets of pipe joints 231 is connected to a spraying unit 24 for spraying the composite coating onto the surface of the fly ash cement-based steel floor. Each spraying unit 24 includes a pipe 241 connected to one end of the pipe joint 231 via a hose 245. This pipe 241 is used to store the composite material and is vertically positioned relative to the storage pipe 23. The pipe 241 has a connector 244, and the hose 245 is connected to one end of the connector 244. Two sets of nozzles 243 are also connected and installed on the pipe 241. The spraying direction of the nozzles 243 is directed towards the conveyor belt 12. Figure 3 Based on this, the three sets of pipes 241 are defined from left to right as the first pipe, the second pipe, and the third pipe, wherein the second pipe is connected to one end of the pipe joint 231 by a rigid pipe.

[0033] After the external feeding equipment is started, the composite coating begins to be conveyed through the feed pipe 22. Since the feed pipe 22 is connected to the external feeding equipment and one end extends into the spray hood 21 and connects to the storage pipe 23, the composite coating flows smoothly into the storage pipe 23. The storage pipe 23 serves as an intermediate storage and distribution device for the coating, and three sets of pipe fittings 231 are connected to it at equal intervals by threads. After the composite coating accumulates in the storage pipe 23, it is distributed to each spraying unit 24 through these three sets of pipe fittings 231.

[0034] In each spraying unit 24, the pipe connector 231 is connected to the pipe 241 via a flexible hose 245. This connection method allows for more flexible adjustment of the position and angle of the pipe 241, better adapting to different spraying needs. The composite coating enters the flexible hose 245 through the pipe connector 231 and then flows into the pipe 241. The connector 244 on the pipe 241 is the connection point of the flexible hose 245, ensuring the continuity of coating delivery. After entering the flexible hose 245, the coating flows to the two sets of spray nozzles 243 connected to it.

[0035] At this time, the fly ash cement-based steel floor, continuously conveyed on the conveyor belt 12, passes under the cover assembly 2. Since the spraying direction of the nozzle 243 is set towards the conveyor belt 12, the composite coating sprayed from the nozzle 243 accurately covers the surface of the steel floor, thereby completing the spraying operation of the composite coating on the surface of the steel floor.

[0036] In one specific embodiment, refer to Figure 1 , Figure 3 and Figure 5 As shown, in order to perform spraying operations on fly ash cement-based steel floors with a large width range (such as 1000mm-1200mm), a distance adjustment unit 27 is installed inside the spraying hood 21. The distance adjustment unit 27 includes two sets of guide rails 271 fixedly installed on the inner wall of the spraying hood 21. There is a certain gap between the two sets of guide rails 271, and the two sets of guide rails 271 are located on both sides of the nozzle 243. Two sets of sliders 272 are slidably installed on the guide rails 271.

[0037] A pipe rack 273 is connected between two sets of horizontally arranged sliders 272 on two sets of guide rails 271. The pipe rack 273 has two sets of pipe clamps 274. The two sets of distance adjustment units 27 have pipe clamps 274 on the pipe rack 273 for respectively connecting and fixing the first pipe and the third pipe. At the same time, there are limiting parts 242 at both ends of the pipe 241 to limit the two sets of pipe clamps 274. There is a certain gap between the two sets of pipe clamps 274 and they are respectively attached to the limiting parts 242 on the pipe 241. The pipe 241 is movably arranged between the two sets of pipe clamps 274.

[0038] In this embodiment, the slider 272 can be fixedly connected to the guide rail 271 by bolts, so as to slide the first pipe and the third pipe along the straight direction of the guide rail 271, so as to adjust the distance between the first pipe and the third pipe and the second and third pipes respectively. At the same time, multiple sets of screw holes adapted to the bolts are opened at equal intervals on the guide rail 271.

[0039] When spraying is required on fly ash cement-based steel floors with a width ranging from 1000mm to 1200mm, the distance adjustment unit 27 operates on the following principle:

[0040] Before spraying begins, the operator adjusts the position of the spraying unit 24 according to the actual width of the steel floor to be sprayed. The two sets of guide rails 271 in the distance adjustment unit 27 are pre-fixed to the inner wall of the spray hood 21 and located on both sides of the nozzle 243. The pipe rack 273 is mounted on the guide rails 271 via sliders 272. The pipe clamps 274 on the pipe rack 273 are respectively fitted and fixed to the pipes 241 on the first pipe and the third pipe. The limiting parts 242 at both ends of the pipe 241 cooperate with the pipe clamps 274 to ensure that the pipe 241 can move between the pipe clamps 274.

[0041] The operator first loosens the bolts fixing the slider 272 to the guide rail 271, allowing the slider 272 to slide freely on the guide rail 271. Then, the operator pushes the pipe rack 273 along the straight direction of the guide rail 271 according to the width of the steel floor. Since the pipe rack 273 is connected to the slider 272, and the pipe clamp 274 fixes the pipes 241 on the first and third pipes, pushing the pipe rack 273 will cause the first and third pipes to move accordingly, thereby changing the distance between the first and third pipes and the second pipe, respectively.

[0042] Once the first and third pipes are moved to the appropriate positions, i.e., the distance between them and the second pipe is sufficient to ensure that the composite coating sprayed from the nozzle 243 can evenly cover the width of the steel floor, the operator passes the bolt through the slider 272 and screws it into the matching screw hole on the guide rail 271. In this way, the slider 272 is fixed on the guide rail 271, and the positions of the pipe rack 273 and the first and third pipes connected to it are also fixed.

[0043] After the above adjustments and fixation are completed, the external feeding equipment will transport the composite coating through the guide pipe 22 to the storage pipe 23, then through the pipe joint into the pipe 241, and finally spray it out from the nozzle 243, evenly covering the surface of the steel floor that has been transported by the conveyor belt 12 to the spraying hood 21, thus completing the spraying operation on the wider steel floor.

[0044] In another specific embodiment, refer to Figures 2 to 4 As shown, in order to perform spraying operations on fly ash cement-based steel floors with a large width range (such as 800mm-1000mm), an angle adjustment unit 25 for fine-tuning the angle of the nozzle 243 is installed on the inner wall of the spraying hood 21. The angle adjustment unit 25 includes a slide plate 251 installed on the inner wall of the spraying hood 21 by fasteners. The slide plate 251 has two sets of T-slots 257, and two sets of opposing first racks 254 are slidably installed in the two sets of T-slots 257. At the same time, a forward and reverse motor 252 is fixedly installed on the side of the slide plate 251 near the conveyor belt 12. The output end of the forward and reverse motor 252 passes through the slide plate 251, and a first gear 253 that meshes with the two sets of first racks 254 is fixedly installed at its output end.

[0045] Meanwhile, a second rack 255 is fixedly installed on the two sets of first racks 254 on their opposite sides, and a second gear 256 is fixedly installed on the opposite ends of the first pipe and the third pipe, and the second gear 256 meshes with the second rack 255.

[0046] It should be noted that this embodiment can be used in conjunction with the second embodiment. That is, the first pipe and the third pipe are respectively fixed to a certain initial position on the guide rail 271 by the slider 272 on the pipe rack 273. That is, the first pipe and the third pipe are in a position close to the second pipe. At the same time, the number of teeth on the second rack 255 is only suitable for enabling the nozzles 243 on the first pipe and the third pipe to achieve an angle adjustment within 15 degrees.

[0047] When spraying fly ash cement-based steel floors with a width range of 800mm-1000mm, the angle adjustment unit 25 operates on the following principle:

[0048] When the nozzle 243 needs to be finely adjusted based on the actual width of the steel floor and the specific spraying process requirements, the operator turns on the forward and reverse motor 252. The forward and reverse motor 252 starts operating, and its output drives the first gear 253 to rotate. Since the first gear 253 meshes with two sets of first racks 254, the rotation of the first gear 253 drives the two sets of first racks 254 to move in opposite or opposing linear motions within the T-slot 257. The specific direction of motion depends on the rotation direction of the first gear 253. If it rotates clockwise, one set of first racks 254 slides in one direction along the T-slot 257, while the other set slides in the opposite direction; if it rotates counterclockwise, the direction of motion is reversed.

[0049] When the first rack 254 slides, the second rack 255, which is fixedly connected to it, moves synchronously. Since the second gear 256 meshes with the second rack 255, the movement of the second rack 255 drives the second gear 256 to rotate. Because the second gear 256 is fixed to the ends of the first and third pipes, the rotation of the second gear 256 causes the first and third pipes to rotate around their axis, thereby driving the connected nozzle 243 to perform fine-tuning of its angle.

[0050] Due to the limited number of teeth on the second rack 255, the angle adjustment range of the nozzle 243 is limited to within 15 degrees. When the nozzle 243 is adjusted to a suitable angle to meet the current spraying requirements of the steel floor, the operator turns off the forward and reverse motors 252. At this time, the first gear 253 stops rotating, the first rack 254 and the second rack 255 stop sliding, and the second gear 256 also stops rotating. The fine-tuning of the nozzle 243's angle is complete, and normal spraying operations can then proceed.

[0051] The angle adjustment unit 25 can work in conjunction with the second embodiment. First, the initial positions of the first pipe and the third pipe on the guide rail 271 are determined by the second embodiment. Then, the nozzle 243 is finely adjusted within a 15-degree range using this embodiment, thereby effectively adapting to the spraying requirements of steel floors of different widths and ensuring the uniformity and accuracy of the spraying effect.

[0052] This angle adjustment unit 25, driven by a forward and reverse motor 252, uses gears and racks to achieve flexible fine-tuning of the nozzle 243 angle, adapting to the spraying requirements of steel floors of different widths. Furthermore, this embodiment can be combined with the second embodiment. First, the initial positions of the first and third pipes on the guide rail 271 are determined using the second embodiment, and then this embodiment is used for further fine-tuning of the nozzle 243 angle, thereby better completing the spraying operation.

[0053] In another specific embodiment, refer to Figures 2 to 4 As shown, a protective cover 28 is fixedly installed inside the spray cover 21. The protective cover 28 is used to cover the cover assembly 2, and the protective cover 28 has two sets of elongated slots (not shown in the figure) for adjusting the position and angle of the spray head 243.

[0054] The protective cover 28 is pre-installed inside the spray cover 21 by bolts, forming a fully enclosed protective structure for the cover assembly 2 (including core components such as the material storage pipe 23, pipe connector 231, and spraying unit 24). Its core function is:

[0055] The enclosed cavity design isolates the spraying area of ​​the composite coating from the external environment, effectively preventing the atomized coating generated during the spraying process from splashing onto the outside of the equipment or the work space, avoiding workshop pollution and material waste, while reducing the risk of operators being exposed to harmful dust.

[0056] The two sets of elongated slots on the protective cover 28 (though not shown in the figure, they can be understood as strip-shaped openings extending along the guide rail 271 or the adjustment direction of the nozzle 243) provide mechanical movement space for the position adjustment (such as sliding along the guide rail 271 with the first and third pipes) and angle adjustment (such as driving the nozzle 243 to deflect via the angle adjustment unit 25). The width and length of the elongated slots are precisely designed to allow the nozzle 243 and its connected pipe 241 to move or rotate freely within a certain range, while also limiting the movement trajectory through the edge of the slot to prevent equipment interference caused by excessive displacement.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
