Description

Technical Field

[0001] This utility model relates to the field of spraying devices, specifically a waterproof coating device for waterproof and anti-corrosion engineering construction. Background Technology

[0002] Waterproof coating spraying equipment is a highly efficient mechanized construction device used for waterproofing and anti-corrosion projects. It uses a high-pressure pump to transport the coating from the storage tank to a multi-nozzle system for uniform spraying. It is often equipped with a stirring mechanism to prevent coating sedimentation. Such devices can significantly improve construction efficiency, coating uniformity and adhesion, and are suitable for building roofs, basements, tunnels and other scenarios.

[0003] In current waterproof coating spraying operations, a method of applying one spray pass followed by half a pass is typically used to increase the coating thickness. However, a problem exists in actual spraying: in half-pass spraying, because the operator relies solely on the strength of their hands and arms to hold and move the spray gun, it is difficult to accurately control the coverage area during spraying, resulting in poor spray uniformity. Therefore, the inventor urgently needs to design a spraying device with marking lines to improve the operator's ability to identify the spraying position and improve the spray uniformity. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a waterproof coating device for waterproof and anti-corrosion engineering construction, so as to solve the technical problem that traditional spraying operations rely heavily on the operator's hand stability, which easily leads to inaccurate control of the coverage area and poor coating uniformity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof coating application device for waterproof and anti-corrosion engineering construction, comprising a plurality of spray guns, a support assembly mounted below the plurality of spray guns, and a marking mechanism installed above any one of the spray guns; the marking mechanism is used to project a longitudinally visible straight line onto the wall surface to be sprayed, providing marking marks for reciprocating spraying.

[0006] By adopting the above technical solution, the assembly structure of multiple spray guns and support components enables multi-nozzle collaborative operation, which greatly improves construction efficiency and is particularly suitable for large-area waterproofing and anti-corrosion projects. At the same time, by installing a marking mechanism above each spray gun, the projected longitudinal visible straight line provides operators with accurate visual reference.

[0007] Furthermore, the marking mechanism includes a mounting base, which is bolted to the top of any spray gun, and a rotating seat with damping is located on the top of the mounting base.

[0008] By adopting the above technical solution, the stability and reliability of the connection with the spray gun are ensured, and vibration and displacement during construction are avoided. At the same time, the use of a damped rotating seat allows operators to easily and infinitely adjust the laser projection angle without the use of tools.

[0009] Furthermore, a support base is fixedly installed above the rotating seat, and a connecting base is rotatably connected above the support base. A line laser marking projector is fixedly installed above the connecting base. The line laser marking projector is electrically connected to an external power source via a switch. The line laser marking projector projects a longitudinally visible marking line onto the wall, and the marking line coincides with the edge line of the previous spraying.

[0010] By adopting the above technical solution and multi-level damping rotation connection structure, the marking mechanism can be flexibly adjusted in multiple dimensions, enabling the single-line laser marking projector to accurately project onto a specific location on any complex construction surface.

[0011] Furthermore, the support assembly includes a base plate, with side plates fixedly disposed on the outer periphery of the base plate and a cavity formed on the inner side, the cavity being used to receive dripping or splashed paint.

[0012] By adopting the above technical solution, the cavity structure formed by the base plate and side plates effectively collects the paint dripping and splashing during construction, solving the problems of paint contamination of the work surface and waste of materials in traditional construction.

[0013] Furthermore, an absorbent layer is attached to the lower inner side of the cavity, and the absorbent layer is replaceable and removable. A handle is fixedly installed on one side of the bottom plate.

[0014] By adopting the above technical solution, a replaceable absorbent layer is set in the cavity, which can efficiently absorb and fix the collected liquid coating, preventing it from flowing or splashing in the cavity, and further improving the coating recycling effect and on-site cleanliness.

[0015] Furthermore, the support assembly also includes a mounting plate with a mounting groove on its surface. Several spray guns are threadedly connected to a fastening handwheel below them, and the fastening handwheel passes through the mounting groove and is fastened to the mounting plate. The mounting groove is a straight groove structure used to adjust the spacing between adjacent spray guns.

[0016] By adopting the above technical solution, and by opening a straight groove on the mounting plate and using a fastening handwheel, the spacing between multiple spray guns can be flexibly and continuously adjusted, enabling a single device to adapt to different engineering requirements for spray width and overlap.

[0017] Furthermore, the paint input ends of several of the spray guns are connected to an external paint storage device via connecting pipes and a pump body.

[0018] By adopting the above technical solution, centralized material supply and continuous operation are achieved, avoiding the inefficiency problem of frequent interruptions in construction and coating addition in traditional operations.

[0019] Furthermore, the spray gun is provided with a splash-proof mechanism on the outside of the nozzle. The splash-proof mechanism includes a baffle. The surface of the baffle is provided with a through groove for the nozzle to pass through. The through groove is opened along the length line of the baffle and has a straight groove structure. The baffle is composed of two V-shaped inclined plates on both sides and a middle connecting plate. The inclined plates guide the blocked paint into the cavity.

[0020] By adopting the above technical solution, the U-shaped baffle can effectively prevent the paint from flying around during high-pressure spraying, thus solving the problems of paint waste and environmental pollution.

[0021] In summary, the present invention has the following main advantages: 1. In this utility model, a laser marking mechanism that can be adjusted in multiple dimensions is installed above the spray gun, which solves the problem of inaccurate coating coverage caused by the traditional half-gun spraying process relying entirely on manual experience. The laser marking provides operators with a precise visual reference, transforming the control of the spraying position from subjective judgment to objective quantification, and significantly improving the uniformity of the coating and the consistency of construction quality.

[0022] 2. In this utility model, the device adopts a multi-spray gun setting and adjustable spacing structure. The spray gun spacing can be flexibly adjusted through the mounting groove and fastening handwheel, so that the equipment can adapt to the spraying width of different engineering requirements, greatly improve construction efficiency and reduce equipment configuration costs.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] In this embodiment: A waterproof coating application device for waterproof and anti-corrosion engineering construction, such as Figure 1-4 As shown, the system includes several spray guns 2, with a support assembly 1 mounted below each spray gun 2. A marking mechanism 5 is installed above any spray gun 2. The marking mechanism 5 projects a longitudinally visible straight line onto the wall to be sprayed, providing marking marks for reciprocating spraying. The assembly structure of multiple spray guns 2 and the support assembly 1 enables multi-nozzle collaborative operation, significantly improving construction efficiency. It is particularly suitable for large-area waterproofing and anti-corrosion projects. At the same time, by installing the marking mechanism 5 above each spray gun, the projected longitudinally visible straight line provides operators with accurate visual references, completely solving the quality problems of inaccurate coverage and uneven coating thickness caused by relying entirely on manual experience in the traditional half-gun spraying process. This transforms the construction process from relying on experience to quantifiable and standardized precise operation.

[0027] See Figure 4 The marking mechanism 5 includes a mounting base 501, which is bolted to the top of any spray gun 2. A damped rotating seat 502 is located above the mounting base 501, ensuring the stability and reliability of the connection with the spray gun 2 and preventing vibration and displacement during construction. At the same time, the damped rotating seat 502 allows operators to easily and infinitely adjust the laser projection angle without using tools and maintain stable positioning at any angle. This greatly improves the convenience of construction adjustment and the accuracy of marking positioning, adapting to different construction environments and angle requirements.

[0028] See Figure 4 A support base 503 is fixedly installed above the rotating base 502. A connecting base 504 is connected to the support base 503 via a damped rotatable connection. A linear laser marking projector 505 is fixedly installed above the connecting base 504. The linear laser marking projector 505 is electrically connected to an external power source via a switch. The multi-stage damped rotatable connection structure enables flexible adjustment of the marking mechanism 5 in multiple dimensions, allowing the linear laser marking projector 505 to accurately project onto a specific location on any complex construction surface. At the same time, the laser marking device is controlled by an independent switch and connected to an external power source, ensuring stable operation over a long period of time. The clear and bright laser line it produces provides operators with an indisputable visual benchmark, greatly reducing construction errors caused by blurred vision or misjudgment.

[0029] See Figure 1 , Figure 2 , Figure 3 The support component 1 includes a base plate 101, with side plates 102 fixedly installed on the outer periphery of the base plate 101 and a cavity 103 formed on the inner side. The cavity 103 is used to receive dripping and splashing paint. Through the cavity 103 structure formed by the base plate 101 and the side plates 102, the paint dripping and splashing during construction is effectively collected, solving the problems of paint contamination of the work surface and waste of materials in traditional construction. At the same time, it not only keeps the construction site clean and reduces the amount of cleaning work, but more importantly, it prevents safety hazards such as slipping caused by paint accumulation on the ground, reflecting the concept of safe and civilized construction.

[0030] See Figure 1 , Figure 2 , Figure 3 The cavity 103 has an absorbent layer underneath its inner side, which is replaceable and removable. A handle 107 is fixedly installed on one side of the bottom plate 101. The replaceable absorbent layer inside the cavity 103 can efficiently absorb and fix the collected liquid paint, preventing it from flowing or splashing inside the cavity, thus further improving the paint recycling effect and on-site cleanliness. At the same time, by providing a handle 107 on one side of the bottom plate 101, an ergonomic point of force is provided for the operator, making the movement, turning and positioning of the entire device more effortless and precise, reducing labor intensity and improving the ease of operation.

[0031] See Figure 1 , Figure 2 , Figure 3 The support assembly 1 also includes a mounting plate 104. The surface of the mounting plate 104 is provided with a mounting groove 105. Several spray guns 2 are fastened to the mounting plate 104 by a fastening handwheel 106 and the mounting groove 105. The mounting groove 105 is a straight groove structure and is used to adjust the spacing between adjacent spray guns 2. By using the mounting groove 105 with a straight groove structure on the mounting plate 104, in conjunction with the fastening handwheel 106, the spacing between multiple spray guns 2 can be flexibly and continuously adjusted, so that a set of devices can adapt to the spraying width and overlap rate of different engineering requirements. At the same time, it makes the installation, disassembly and maintenance of the spray guns very convenient, greatly enhancing the applicability and functionality of the equipment and reducing the cost of configuring special equipment for different engineering needs.

[0032] See Figure 1 , Figure 2 , Figure 3 The paint input ends of several spray guns 2 are connected to an external paint storage device through a connecting pipe 4 and a pump body, realizing centralized material supply and continuous operation. This avoids the inefficiency problem of frequent interruptions in construction and paint addition in traditional operations. At the same time, it ensures that the paint pressure and quality supplied to each spray gun are consistent, fundamentally eliminating the uneven coating caused by differences in the output of each spray gun, and significantly improving the stability and reliability of the overall construction quality.

[0033] See Figure 1 , Figure 2 , Figure 3 The spray gun 2 has a splash-proof mechanism 3 on the outside of the nozzle. The splash-proof mechanism 3 includes a baffle 301 with a U-shaped cross-section. The surface of the baffle 301 has a through groove 302 for the nozzle to pass through. The inner side of the baffle 301 is set with an incline to guide the blocked paint into the cavity 103. The U-shaped baffle 301 can effectively prevent the paint from flying around during high-pressure spraying, solving the problems of paint waste and environmental pollution. At the same time, the incline on the inner side of the baffle guides the blocked paint into the cavity 103. The through groove 302 ensures the normal operation of the nozzle without affecting the splash-proof effect, significantly improving material utilization and construction cleanliness.

[0034] The implementation principle of this embodiment is as follows: A cavity 103 for receiving dripping paint is formed by the base plate 101 and side plate 102 of the support component 1. During operation, several spray guns 2 fixed and spaced on the mounting plate 104 by the mounting groove 105 perform spraying operations, thereby improving the spraying applicability of the several spray guns 2. The marking mechanism 5 installed above the spray gun 2 projects a longitudinal visible laser line onto the wall. This straight line should be projected onto the outermost edge line of the previous spraying to ensure that the half-gun spraying operation is uniformly achieved during the current spraying process. The mechanism flexibly adjusts the angle of the laser marking projector 505 through the damping rotation structure of the mounting base 501, rotating base 502, support base 503 and connecting base 504, providing the operator with a precise visual reference for the half-gun coverage position. At the same time, the anti-splash mechanism 3 on the outside of the spray gun 2 guides the splashed paint into the replaceable absorbent layer in the cavity 103 through its U-shaped baffle 301 and inclined surface, thereby improving the uniformity of spraying while ensuring a clean construction environment.
