Description

Technical Field

[0001] This utility model relates to the field of pipeline processing technology, and in particular to a pipeline spray cooling device. Background Technology

[0002] Pipes are a type of steel material with a hollow cross-section, and they have a wide range of applications in construction, machinery, and other fields. For example, steel pipes often need to be cut or welded during the production process, which can cause burrs on the inner wall of the pipe, affecting its actual performance. Generally, during the use of pipes, it is necessary to grind off the burrs on the inner wall. Existing grinding equipment usually involves inserting a grinding and polishing device into the inside of the pipe and removing the burrs on the inner wall by high-speed rotation. This generates a lot of heat, which requires cooling the pipe.

[0003] Conventional cooling processes require a continuous supply of cooling medium to suppress grinding heat. However, due to the limited space inside the pipe, the heat exchange efficiency of existing cooling systems is significantly limited, and their location is fixed. Traditional single cooling systems are limited by their fixed structure and can only be barely adapted within a very narrow range of pipe diameters, making it difficult to cover diverse specifications.

[0004] Therefore, there is an urgent need for a pipeline spray cooling device that has a wide range of applications and good cooling effect. Utility Model Content

[0020] 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.

[0021] The purpose of this invention is to provide a pipeline spray cooling device to solve the problems existing in the prior art. It achieves cooling of the pipeline to be cooled by a movable cooling mechanism on the outer periphery of the pipeline, thereby improving the applicability and cooling effect.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2As shown, a pipe spray cooling device is provided, including a linear drive mechanism, a profile frame 5, and a cooling sprayer 7. The profile frame 5 is arranged around the circumference of the pipe 15 to be sprayed. The cooling sprayer 7 is arranged on the inner wall of the profile frame 5 near the pipe 15 to be sprayed. The cooling sprayer 7 is connected to the equipment supplying coolant through a pipeline. The cooling sprayer 7 is used to spray coolant in an atomized state onto the pipe 15 to achieve cooling of the pipe 15 to be sprayed. The coolant can be water or other liquids that can cool pipes. The cooling spray is carried out on the outer circumference of the pipe 15 to be sprayed, which is not limited by the narrow space inside the pipe 15 to be sprayed, thus improving the applicability of the device. The movement direction of the linear drive mechanism is parallel to the axis of the pipe 15 to be sprayed. The linear drive mechanism is connected to the profile frame 5 and drives the profile frame 5 to move along the axial direction of the pipe 15 to be sprayed. That is, the linear drive mechanism can drive the profile frame 5 and the cooling sprayer 7 to move along the axial direction of the pipe 15 to achieve multi-point spray cooling and spray cooling for high-temperature points during grinding, thereby improving the cooling effect.

[0024] Since the purpose of providing cooling is to reduce the impact of high temperatures during the grinding process, the cooling spray is actually for controlling the temperature of the pipe 15 to be sprayed. For this purpose, a temperature sensor 8 is installed on the inner wall of the profile frame 5 to detect the temperature of the pipe 15 to be sprayed. Using the temperature detection function of the temperature sensor 8, the temperature data on the pipe 15 to be sprayed corresponding to the profile frame 5 is detected. The control system can adjust the spray volume according to the temperature data. When the temperature is high, the spray volume is increased to ensure the cooling effect, and when the temperature is low, the spray volume is reduced to save resources. The temperature sensor 8 can be a non-contact sensor, which can be used for pipes of different specifications, thus improving the applicability of the device. Of course, if this device is used to cool pipes of the same specification, a contact temperature sensor 8 can also be selected.

[0025] In one embodiment, the profile frame 5 is in the shape of an inverted U and is fastened to the pipe 15 to be sprayed. Multiple cooling sprayers 7 and multiple temperature sensors 8 are provided on the inner peripheral wall of the profile frame 5 to improve the cooling effect and temperature detection accuracy.

[0026] Multiple cooling sprayers 7 are evenly distributed to improve cooling uniformity, and multiple temperature sensors 8 can be respectively set on the bottom arm and support arm of the U-shaped structure to further improve temperature detection accuracy.

[0027] The linear drive mechanism can be an electric / pneumatic / hydraulic push rod. The control system controls the push rod to move, realizing the axial movement of the profile frame 5 along the spray pipe 15. When push rods are used, multiple push rods can be used to drive the profile frame 5 to move together, improving the movement stability. The linear drive mechanism can also be a wall-climbing robot 9. At least two wall-climbing robots 9 are set on the profile frame 5, with the two wall-climbing robots 9 symmetrically arranged on both sides of the spray pipe 15. The wall-climbing robot 9 includes a base 10 and two adjusting arms. The two adjusting arms are set in a V-shape on the base 10. The adjusting arms include a hinge frame 11, a telescopic cylinder 14, a motor 12, and a wheel set 13. The motor 12 is fixedly mounted on the hinge frame. At one end of 11, the wheel set 13 is connected to the motor 12 for transmission. The end of the hinge frame 11 away from the motor 12 is hinged to the base 10. The two ends of the telescopic cylinder 14 are respectively hinged to the base 10 and the hinge frame 11, or respectively hinged to the base 10 and the motor 12. By controlling the extension and retraction of the telescopic cylinder 14, the angle of the adjusting arm can be adjusted, so that it can be used for different specifications of the spray pipe 15. It can also be adjusted so that the wheel set 13 contacts the surface of the spray pipe 15, so that the profile frame 5 can be driven by the motor 12 to move along the axial direction of the spray pipe 15. The motor 12 can be an electric motor, a pneumatic motor or a hydraulic motor, and the telescopic cylinder 14 can be electric, pneumatic or hydraulic.

[0028] Wheel set 13 can be a standard wheel set or a specially designed wheel set 13. The specially designed wheel set 13 includes a hub and multiple drum-shaped rollers. The hub is key-driven to the motor 12. The multiple drum-shaped rollers are evenly arranged around the circumference of the hub. The axis of the drum-shaped rollers is set at a 45° angle to the axis of the hub. The specific arrangement of the drum-shaped rollers is as follows: the two ends of the drum-shaped rollers are connected to the hub through rolling bearings to form a passive unit that can rotate independently and freely, ensuring that it always maintains line contact with the surface of the spray pipe 15 when moving on the spray pipe 15. End caps can be set at both ends of the hub along the axial direction. The end caps are bolted to the two ends of the hub to prevent the drum-shaped rollers from moving axially and also to seal.

[0029] A rubber layer can be installed around the outer periphery of the drum-shaped roller. The rubber layer can provide both anti-slip and protective effects.

[0030] In one embodiment, a slide rail bracket 1 is provided on the top of the profile frame 5, and a slide rail 2 is provided on the bottom of the slide rail bracket 1. The slide rail 2 is parallel to the axis of the spray pipe 15. A slider 3 is connected to the top of the profile frame 5 through a transition block 4. The slider 3 is slidably connected to the slide rail 2. The slide rail bracket 1 can be fixed on the top of the machine room or other fixed positions. The cooperation between the slide rail 2 and the slider 3 can provide guidance for the movement of the profile frame 5 and improve the stability of the movement of the profile frame 5. In other embodiments, the slide rail bracket 1 can also be provided below the profile frame 5. For example, the two bottoms of the U-shaped structure of the profile frame 5 are connected to the slide rail bracket 1 through the cooperation structure of the slide rail 2 and the slider 3, which can also play a guiding role.

[0031] In one embodiment, the profile frame 5 is hollow inside, and the water supply pipe of the cooling sprayer 7 is laid in the hollow cavity of the profile frame 5. The water supply pipe passes through the profile frame 5 and connects with the water supply equipment. This can make full use of the internal space of the profile frame 5 to provide a path for the water supply pipe, reduce space occupation, and avoid messy pipelines.

[0032] Based on the hollow design of the profile frame 5, the pipelines required for the motor 12 can also be laid in the hollow cavity of the profile frame 5, thereby improving space utilization.

[0033] Since the profile frame 5 is driven by the linear drive mechanism, in order to prevent the pipeline from bending, a drag chain 6 can be installed on one side of the profile frame 5 to protect the water supply pipe. The drag chain 6 can also protect the pipeline of the motor 12.

[0034] A water receiving tube can be installed below the profile frame 5 and the spray pipe 15 to collect the water that has not evaporated after spraying. The water receiving tube can be circulated to the water tank where the water supply equipment is located through the circulation pipeline to realize the recycling of water resources.

[0035] In actual use, the profile frame 5 is moved to the outer periphery of the pipe 15 to be sprayed. The control system controls the wheel set 13 on the adjusting arm of the wall-climbing robot 9 to contact the outer wall of the pipe 15 to be sprayed, and starts the wall-climbing robot 9. The wall-climbing robot 9 generates axial and circumferential compound friction force between the drum-shaped roller and the outer wall of the pipe 15 to be sprayed, which drives the profile frame 5 to move to the area inside the pipe 15 to be sprayed that is being polished. The temperature sensor 8 detects the current pipe temperature, and the control system controls the cooling sprayer 7 to start spraying and adjusts the spray volume according to the temperature. Alternatively, the movement of the profile frame 5 can be actively controlled by the control system to spray and cool other parts of the pipe 15 to be sprayed.

[0036] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
