[0002] Steel-reinforced composite pipes are widely used in water supply and drainage, gas transmission and many other fields due to their advantages such as high strength, corrosion resistance and aging resistance. With the expansion of application scenarios, the requirements for surface wear resistance, impact resistance and service life are constantly increasing. Therefore, it is necessary to strengthen the surface of the pipe by coating with reinforcing agents.

[0003] Existing surface reinforcement equipment for steel-reinforced composite pipes has several shortcomings: some equipment can only process a single pipe at a time, resulting in low processing efficiency and difficulty in meeting the needs of mass production; while some equipment can process multiple pipes simultaneously, it lacks a stable support and guiding structure, making the pipes prone to deviation and shaking during movement, leading to uneven coating of the reinforcing agent. In addition, the drive mechanism of existing equipment is prone to slippage when controlling the pipe to move, which affects the synchronization of conveying and rotation. Furthermore, the continuity of reinforcing agent supply is poor, the curing speed after coating is slow, and the dripping reinforcing agent is difficult to recover, which not only wastes materials but may also pollute the working environment.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Reference Figure 1-7 A surface reinforcement device for steel-reinforced composite pipes includes a support frame 1, multiple strip plates 2, a U-shaped plate 3, an electric cylinder 32, a lifting plate 31, a coating roller 41, a motor 42, a mounting shell 4, a liquid storage tank 44, a support shell 6, and a control panel 7.

[0032] Multiple strip plates 2 are fixedly installed on the support frame 1 and arranged parallel to each other. U-shaped plates 3 are fixedly installed on the top sides of the front and rear strip plates 2. Each strip plate 2 has an arc groove 201, and each arc groove 201 has an overflow port 202 and four mounting slots. Multiple guide wheels 21 are rotatably installed in the four mounting slots. In order to guide the steel skeleton composite pipe along the direction of the arc groove 201 and to achieve the rotation effect when the drive roller 63 controls its lateral movement, so as to facilitate the coating roller 41 to uniformly coat the reinforcing agent on its outer periphery, the axis of the guide wheel 21 is set at an angle of 30-60 degrees with the orientation of the arc groove 201, and the axes of multiple guide wheels 21 located in the same mounting slot are arranged parallel to each other.

[0033] The electric cylinder 32 is fixedly installed on the U-shaped plate 3, and the lifting plate 31 is fixedly installed on the telescopic end of the electric cylinder 32. The bottom side of the lifting plate 31 is fixedly installed with the mounting shell 4, and the coating roller 41 is rotatably installed inside the mounting shell 4. The motor 42 is fixedly installed on the front side of the mounting shell 4, and the output shaft of the motor 42 is fixedly connected to the coating roller 41. The liquid storage tank 44 is fixedly installed on the U-shaped plate 3. The liquid storage tank 44 and the mounting shell 4 are connected to the same conveying pipe 43, and the conveying pipe 43 is equipped with a control valve 431.

[0034] The control panel 7 is fixedly installed on the front side of the U-shaped plate 3 and electrically connected to the motor 42, control valve 431 and electric cylinder 32;

[0035] The support shell 6 is located below the lifting plate 31. Multiple T-shaped rods 61 that are slidably connected to the lifting plate 31 are fixedly installed on the top side of the support shell 6. Each T-shaped rod 61 is movably fitted with a buffer spring 62. The two ends of the buffer spring 62 are fixedly connected to the bottom side of the lifting plate 31 and the top side of the support shell 6, respectively. The horizontal plane of the drive roller 63 in the static state is lower than the horizontal plane of the coating roller 41, which can provide effective support and buffering effect for the support shell 6, thereby ensuring the contact state between the drive roller 63 and the pipe, and thus ensuring an effective driving effect on the pipe.

[0036] A drive roller 63 parallel to the coating roller 41 is rotatably installed inside the support shell 6. A motor 64 electrically connected to the control panel 7 is fixedly installed on the front side of the support shell 6. The output shaft of the motor 64 is axially fixedly connected to the drive roller 63, which can control the drive roller 63 to move laterally along the arc groove 201 when it comes into contact with multiple steel skeleton composite pipes. In order to increase the friction between the drive roller 63 and the pipe, and thus ensure that the drive roller 63 drives the pipe stably, a silicone layer is pasted and fixed on the outer periphery of the drive roller 63.

[0037] A hot air blower 5, electrically connected to the control panel 7, is fixedly installed on the top side of the U-shaped plate 3. The air outlet of the hot air blower 5 is connected to an air supply duct 51, which is fixedly connected to the lifting plate 31. An air guide hood 52, which faces multiple arc grooves 201, is fixedly installed at the air outlet end of the air supply duct 51. This allows the surface of the pipe to be dried after the coating roller 41 has applied the reinforcing agent, thereby accelerating the curing speed of the reinforcing agent and preventing the undried reinforcing agent from being contaminated or resulting in uneven coating during subsequent transportation. In order to evenly disperse the airflow generated by the hot air blower 5 into the interior of the air guide hood 52 and ensure that the air blown out from the air guide hood 52 can fully cover the surface of the coated steel skeleton composite pipe, thereby improving drying efficiency and drying uniformity, the air supply duct 51 has multiple air outlets, and all of the multiple air outlets of the air supply duct 51 extend into the air guide hood 52.

[0038] In this embodiment, in order to ensure normal air supply and delivery without affecting the normal lifting and lowering of the lifting plate 31, the air supply pipe 51 and the delivery pipe 43 near the hot air blower 5 and the liquid storage tank 44 are both made of flexible pipe.

[0039] In this embodiment, in order to collect the dripping reinforcing agent, a collection box 11 located below the strip plate 2 is fixedly installed on the support frame 1. The top side of the collection box 11 is open and located directly below a plurality of overflow ports 202.

[0040] In this embodiment, in order to provide stable guidance for the lifting plate 31 when it moves up and down with the extension end of the electric cylinder 32, effectively prevent the lifting plate 31 from shifting or shaking during the movement, and thus ensure that the coating roller 41 installed on the bottom side of the lifting plate 31 can always maintain precise alignment with the surface of the steel skeleton composite pipe in the multiple arc grooves 201, and ensure the stability and uniformity of the reinforcing agent coating operation, multiple guide rods 33 that are slidably connected to the U-shaped plate 3 are fixedly installed on the top side of the lifting plate 31.

[0041] It is worth noting that the content protected by this application does not involve improvements to software, circuits and methods. Therefore, the circuits, electronic components and module mechanisms involved are all based on existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. Among them, the electric cylinder 32, motor 42, motor 64, control valve 431 and hot air blower 5 are all controlled by the control panel 7.

[0042] Working principle: In use, first connect the power supply, then start the electric cylinder 32 via the control panel 7. The telescopic end of the electric cylinder 32 drives the lifting plate 31 to descend, causing the coating roller 41 and drive roller 63 to gradually approach the arc-shaped groove 201 on the strip plate 2. At this time, the steel-reinforced composite pipe to be processed is placed in the arc-shaped groove 201 of the multiple strip plates 2. The guide wheels 21, which are inclined in the four mounting slots within the arc-shaped groove 201, provide initial positioning and support for the composite pipe. Then, adjust the telescopic amount of the electric cylinder 32 via the control panel 7 to ensure close contact between the drive roller 63 and the surface of the composite pipe. Simultaneously, the coating roller 41 and the composite pipe... Maintaining an appropriate coating spacing on the composite tube surface, the control valve 431 on the delivery pipe 43 is then opened, allowing the reinforcing agent in the storage tank 44 to flow into the mounting housing 4 through the delivery pipe 43, immersing the coating roller 41. Then, motor 1 42 and motor 2 64 are started. Motor 1 42 drives the coating roller 41 to rotate, and motor 2 64 drives the drive roller 63 to rotate. The drive roller 63, through friction with the composite tube, drives the composite tube to move laterally along the arc groove 201. At the same time, the composite tube rotates under the action of the inclined guide wheel 21, enabling the coating roller 41 to uniformly coat the outer periphery of the composite tube with reinforcing agent.

[0043] During the coating process, excess reinforcing agent will flow from the overflow port 202 in the arc groove 201 into the collection box 11 below for recycling. After the coating is completed, the pipe continues to move and passes under the air guide shroud 52. The control panel 7 starts the hot air blower 5. The airflow generated by the hot air blower 5 is delivered to the air guide shroud 52 through the air supply pipe 51. The air guide shroud 52 blows the airflow evenly onto the surface of the composite pipe to quickly dry the coated reinforcing agent.

[0044] The above provides a detailed description of the surface reinforcement equipment for steel-reinforced composite pipes provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
