[0002] Spraying equipment, also known as coating equipment, is specifically defined as a special tool for applying protective or decorative layers to metal and non-metal surfaces.

[0003] With the development of productivity and the progress of society, spraying technology has become increasingly sophisticated. As automation levels rise, spraying production lines are being applied more widely and have penetrated into various sectors of the national economy. To improve the performance of precast concrete components, special coatings are typically sprayed onto them during production. The types of precast concrete components that need spraying are diverse, one of which is spraying the inner walls of tubular precast components with large inner diameters. In existing technologies, spraying is done manually, which not only easily leads to uneven spraying but also makes it easier for harmful substances in the coating to harm the health of operators in a semi-enclosed environment. Therefore, a structure is designed to achieve spraying of the inner walls of precast concrete components.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Special spraying equipment for the inner wall of precast concrete components, such as Figure 1 and Figure 2As shown, the structure includes a top support 1 and a bottom support 2, which are distributed vertically and fixed to each other. The bottom support 2 has several symmetrically arranged support wheels fixedly connected to its bottom, facilitating the movement and handling of the entire structure and making its use more convenient and stable. The top of the top support 1 is fixedly connected to several lifting rings via threaded connections, allowing the entire structure to be lifted and moved more easily. Users can use a crane to lift and raise the entire structure, enabling it to enter the precast concrete component for stable spraying. A guide ring groove 3 surrounds the top support 1 and the bottom support 2. A spraying device 4, which slides circumferentially along the inner side of the guide ring groove 3, is installed within it. The guide ring groove 3 provides stable clearance for the spraying device 4 during its movement. The device then moves circumferentially to achieve stable spraying of the inner wall of the precast concrete component. The spraying device 4 includes a support and a storage box fixed on the support. The storage box is used to store the paint. A pump body connected to the storage box is fixedly connected to the spraying device 4 by bolts. Under the suction of the pump body, the paint in the storage can be stably drawn out. Several spray heads 5 are connected to the spraying device 4 on the side away from the central axis of the top support 1. The spraying direction of the spray heads 5 is away from the central axis of the top support 1. A delivery pipe is fixedly connected to the spraying device 4 by bolts. The delivery pipe is connected to the several spray heads 5. The paint drawn by the pump body is stably delivered into the delivery pipe and sprayed by the spray heads 5. A power supply that moves with the spraying device 4 is fixedly connected to the spraying device 4. The power supply provides stable power and drive to the pump body.

[0024] like Figures 1-5 An annular drive gear 6 is fixedly connected to the top surface of the bottom support 2 by welding. A drive motor 7 is fixedly connected to the spraying device 4 by bolt locking. The drive end of the drive motor 7 is fixedly connected to a drive gear 8 that is transmitted through the annular drive gear 6. The drive motor 7 is a servo motor. During the drive process, the drive motor 7 will drive the drive gear 8 to rotate. During the rotation of the drive gear 8, it will drive the spraying device 4 to move stably through its mutual meshing with the annular drive gear 6, so that the spraying device 4 can move circumferentially and perform spraying.

[0025] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the bottom of the spraying device 4 is rotatably connected to a first front steering seat 9 and a first rear steering seat 10. The drive motor 7 is fixedly connected to the first rear steering seat 10. The first front steering seat 9 and the first rear steering seat 10 are rotatably connected to symmetrically arranged first guide rail wheels 11. The bottom support seat 2 is fixedly connected to two annular guide rails 12 for the first guide rail wheels 11 to slide. The top of the spraying device 4 is rotatably connected to a second front steering seat 13 and a second rear steering seat 14. The bottom of the top support seat 1 is fixedly connected to two annular guide grooves 15 with downward openings. The second front steering seat 13 and the second rear steering seat 14 are rotatably connected to guide rollers 16 that abut against the top wall of the annular guide grooves 15. The second front steering seat 13 and the second rear steering seat 14 are rotatably connected to limiting rollers 17 that abut against the two side walls of the annular guide grooves 15.

Four symmetrically arranged second telescopic drive members 20 are fixedly connected to the bottom of the top support base 1. The drive end of each second telescopic drive member 20 is rotatably connected to a second abutting wheel 21. The driving directions of the first telescopic drive members 18 and the second telescopic drive members 20 are perpendicular to each other. Both the first telescopic drive members 18 and the second telescopic drive members 20 are electric telescopic rods, utilizing the advantages of electric telescopic rods... The stable driving effect ensures that the driving effect of the first telescopic driving member 18 and the second telescopic driving member 20 is more stable. Under the driving action of the first telescopic driving member 18 and the second telescopic driving member 20, the first clamping wheel 19 and the second clamping wheel 21 can be driven to clamp and loosen against the inner wall of the precast component. By abutting the first clamping wheel 19 and the second clamping wheel 21 against the inner bottom surface of the precast component, the overall structure is stably guided and limited during the movement process inside the precast component, making the movement process and spraying process of the overall structure more stable and the spraying effect of the overall structure better.

[0027] like Figure 1 As shown, a number of circumferentially distributed support columns 22 are fixedly connected between the top support 1 and the bottom support 2 by welding. The support columns 22 are used to achieve a stable connection and limit the position of the top support 1 and the bottom support 2. Cameras 23 are fixedly connected to the support columns 22 by bolts. The cameras 23 are circumferentially distributed. The cameras 23 are used to facilitate the operator to observe the spraying situation and adjust the position of the overall structure in a timely manner, so as to improve the overall spraying effect of the structure.
