An adjustable-spacing refrigeration pipe straightening device

Abstract

This utility model discloses an adjustable-spacing refrigeration pipe straightening device, relating to the field of pipe straightening technology. It includes a base plate, a fixed box fixedly mounted at the center of the top of the base plate, and columns fixedly mounted at the four corners of the top of the base plate. A movable box is slidably mounted between the four columns via a lifting assembly. The movable box and the fixed box have the same structure. In use, when the refrigeration pipes have different diameters, a hydraulic cylinder is activated, causing a lifting block to move up and down within a lifting groove, which in turn moves the movable box up and down, adjusting the distance between the upper and lower straightening wheels. This accommodates refrigeration pipes of different diameters, solving the problem of existing refrigeration pipe straightening devices having a fixed spacing. Because the spacing of the straightening equipment is fixed, it is impossible to adjust the spacing according to the pipe specifications when the pipe passes through the straightening device for straightening, resulting in only one size of pipe being straightened, thus affecting the practicality of the pipe straightening device.

Description

Technical Field

[0001] This utility model relates to the field of pipe straightening technology, and in particular to a refrigeration pipe straightening device with adjustable spacing. Background Technology

[0002] A vortex tube is a cooling device that converts thermal energy into cold energy using compressed air within a vortex tube. It is primarily used in areas such as machining cooling, electronic component testing, and laboratory cryogenic experiments. Its working principle is based on the separation effect of compressed air within the vortex tube; one end generates low-temperature cold air, while the other releases high-temperature hot air. Precise control of temperature and flow rate can be achieved by adjusting the valve at the hot air end. Refrigeration tubes have no moving parts, require no chemical refrigerant, and rely on airflow for cooling. They are characterized by their compact structure, resistance to electromagnetic interference, and tolerance to high-temperature and high-humidity environments.

[0003] Traditional refrigeration pipe straightening devices have a fixed spacing. When pipes pass through the straightening device for straightening, the fixed spacing makes it impossible to adjust the spacing according to the pipe specifications. This results in the device being able to straighten only one size of pipe, thus affecting its practicality. Therefore, it is necessary to propose an adjustable spacing refrigeration pipe straightening device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable spacing refrigeration pipe straightening device to solve the problem mentioned in the background art that the spacing of existing refrigeration pipe straightening devices is fixed. When the pipe passes through the straightening device for straightening, the spacing of the straightening device is fixed, and it is impossible to adjust the spacing according to the specifications of the pipe, resulting in only one size of pipe being straightened, which affects the practicality of the pipe straightening device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable spacing refrigeration pipe straightening device, including a base plate, a fixed box fixedly installed in the middle of the top of the base plate, and columns fixedly installed at the four corners of the top of the base plate. A movable box is slidably installed between the four columns through a lifting assembly. The movable box and the fixed box have the same structure.

[0006] The lifting assembly includes four hydraulic cylinders, which are respectively fixedly mounted on the top of four columns. The columns have lifting grooves inside, and lifting blocks are slidably arranged inside the lifting grooves. The lifting blocks are fixedly connected to the movable box. The telescopic ends of the hydraulic cylinders extend into the lifting grooves and are fixedly connected to the lifting blocks.

[0007] The fixed box has a rotating shaft inside, which is rotatably arranged by a limiting component. There are several rotating shafts, which are equidistantly distributed. A straightening wheel is fixedly installed on the outer ring of the rotating shaft. The fixed box has a power component that drives the rotating shaft to rotate.

[0008] Preferably, the power assembly includes a motor, which is fixedly mounted on the side of the fixed housing. A worm gear is fixedly mounted on the outer ring of the rotating shaft. A drive shaft is rotatably mounted inside the fixed housing. A plurality of equidistant worms are fixedly mounted on the outer ring of the drive shaft. The number of worms and worm gears is the same, and the worms and worm gears mesh with each other. The output end of the motor extends movably into the interior of the fixed housing and is fixedly connected to the drive shaft.

[0009] Preferably, the limiting component includes two sets of limiting parts, which are located at both ends of the rotating shaft. Each set of limiting parts includes two cylinders, which are symmetrically distributed about the center line of the rotating shaft. The cylinders are fixedly installed on the inner wall of the fixed box. A semi-circular arc plate is fixedly installed at the telescopic end of the cylinder. The rotating shaft rotates between the two semi-circular arc plates, and the semi-circular arc plates and the rotating shaft are in movably fitted together.

[0010] Preferably, the end of the rotating shaft is movably fitted against the inner wall of the fixed box.

[0011] Preferably, the straightening wheel protrudes from the upper surface of the fixing box.

[0012] Preferably, a wear-resistant layer is provided on the side of the semi-circular arc plate near the rotation axis.

[0013] Preferably, the lifting groove and the lifting block are adapted to each other.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In use, the refrigeration pipes to be straightened are placed between the upper and lower straightening wheels. The power assembly drives the rotating shaft and straightening wheels to rotate, thereby conveying and straightening the refrigeration pipes. When the diameters of the refrigeration pipes are different, the hydraulic cylinder is activated, which drives the lifting block to move up and down inside the lifting groove, thereby driving the movable box to move up and down and adjusting the distance between the upper and lower straightening wheels. This accommodates refrigeration pipes of different diameters, solving the problem that existing refrigeration pipe straightening devices have a fixed spacing. When the pipes pass through the straightening device for straightening, the fixed spacing of the straightening equipment makes it impossible to adjust the spacing according to the specifications of the pipes, resulting in only one size of pipe being straightened, which affects the practicality of the pipe straightening device.

[0016] 2. By setting up four hydraulic cylinders, lifting blocks and lifting grooves, the same force is applied to the four corners of the movable box, and the vertical displacement trajectory of the movable box is limited to ensure the stability of the vertical displacement of the movable box.

[0017] 3. When one of the straightening wheels is damaged, the corresponding cylinder is activated to move the semi-circular plate away from the rotating shaft, thereby removing the restriction on the rotating shaft. This makes it easier to remove the damaged straightening wheel, replace it with a new one, and then install it in reverse. This improves the convenience of device maintenance and extends the service life of the device. Attached Figure Description

[0024] 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.

[0025] This utility model provides, for example Figures 1-5 The adjustable spacing refrigeration pipe straightening device shown includes a base plate 1, a fixed box 3 fixedly installed in the middle of the top of the base plate 1, and columns 2 fixedly installed at the four corners of the top of the base plate 1. A movable box 4 is slidably installed between the four columns 2 through a lifting assembly. The movable box 4 has the same structure as the fixed box 3.

[0026] The lifting assembly includes four hydraulic cylinders 5, which are fixedly installed on the top of four columns 2. The inside of the column 2 is provided with a lifting groove, and a lifting block 6 is slidably installed inside the lifting groove. The lifting groove and the lifting block 6 are compatible. The lifting block 6 is fixedly connected to the movable box 4. The telescopic end of the hydraulic cylinder 5 extends into the inside of the lifting groove and is fixedly connected to the lifting block 6.

[0027] The fixed box 3 has a rotating shaft 7 inside which is rotatably installed by a limiting component. There are several rotating shafts 7, which are equidistantly arranged. A straightening wheel 10 is fixedly installed on the outer ring of the rotating shaft 7. The straightening wheel 10 protrudes from the upper surface of the fixed box 3. The fixed box 3 has a power component that drives the rotating shaft 7 to rotate inside. The internal structure of the movable box 4 is the same as that of the fixed box 3.

[0028] Specifically, in use, the refrigeration pipes to be straightened are placed between the upper and lower straightening wheels 10. The power assembly drives the rotating shaft 7 and the straightening wheels 10 to rotate, thereby conveying and straightening the refrigeration pipes. When the diameters of the refrigeration pipes are different, the hydraulic cylinder 5 is activated, causing the lifting block 6 to move up and down inside the lifting groove, which in turn causes the movable box 4 to move up and down, adjusting the distance between the upper and lower straightening wheels 10. This accommodates refrigeration pipes of different diameters, solving the problem that existing refrigeration pipe straightening devices have a fixed spacing. When pipes pass through the straightening device for straightening, the fixed spacing of the straightening equipment makes it impossible to adjust the spacing according to the pipe specifications, resulting in only one size of pipe being straightened, thus affecting the practicality of the pipe straightening device.

[0029] In addition, by setting up four hydraulic cylinders 5, lifting blocks 6 and lifting grooves, the same force is applied to the four corners of the movable box 4, and the vertical displacement trajectory of the movable box 4 is limited to ensure the stability of the vertical displacement of the movable box 4.

[0030] Furthermore, the power assembly includes a motor 12, which is fixedly mounted on the side of the fixed housing 3. A worm gear 11 is fixedly mounted on the outer ring of the rotating shaft 7. A drive shaft 13 is rotatably mounted inside the fixed housing 3. Several worms 14 are equidistantly arranged on the outer ring of the drive shaft 13. The number of worms 14 and worm gears 11 is the same, and the worms 14 and worm gears 11 mesh with each other. The output end of the motor 12 extends movably into the interior of the fixed housing 3 and is fixedly connected to the drive shaft 13. When the motor 12 is started, it drives the drive shaft 13 and worms 14 to rotate, which in turn drives the worm gears 11 to rotate, so that multiple rotating shafts 7 rotate synchronously, and thus multiple straightening wheels 10 rotate synchronously.

[0031] Furthermore, the limiting assembly includes two sets of limiting parts, which are located at both ends of the rotating shaft 7. Each set of limiting parts includes two cylinders 8, which are symmetrically distributed about the center line of the rotating shaft 7. The cylinders 8 are fixedly installed on the inner wall of the fixed box 3. A semi-circular arc plate 9 is fixedly installed at the telescopic end of the cylinder 8. The rotating shaft 7 rotates between the two semi-circular arc plates 9, and the semi-circular arc plates 9 and the rotating shaft 7 are in movable contact. The end of the rotating shaft 7 is in movable contact with the inner wall of the fixed box 3. When one of the straightening wheels 10 is damaged, the corresponding cylinder 8 is activated, which drives the semi-circular arc plate 9 away from the rotating shaft 7, thereby removing the restriction on the rotating shaft 7. This makes it easy to remove the damaged straightening wheel 10, replace it with a new straightening wheel 10, and then install it in reverse, improving the convenience of device maintenance and extending the service life of the device.

[0032] Furthermore, a wear-resistant layer is provided on the side of the semi-circular arc plate 9 near the rotating shaft 7, which extends the service life of the semi-circular arc plate 9.

[0033] Working Principle: In use, the refrigeration pipe to be straightened is placed between the upper and lower straightening wheels 10. The motor 12 is started, driving the drive shaft 13 and worm gear 14 to rotate, which in turn drives the worm wheel 11 to rotate, causing multiple rotating shafts 7 to rotate synchronously, and thus multiple straightening wheels 10 to rotate synchronously. The upper and lower straightening wheels 10 rotate in opposite directions, thereby conveying and straightening the refrigeration pipe. When the diameter of the refrigeration pipe is different, the hydraulic cylinder 5 is activated, driving the lifting block 6 to move up and down inside the lifting groove, which in turn drives the movable box 4 to move up and down, adjusting the distance between the upper and lower straightening wheels 10 to accommodate refrigeration pipes of different diameters. When one of the straightening wheels 10 is damaged, the corresponding cylinder 8 is activated, driving the semi-circular plate 9 away from the rotating shaft 7, removing the restriction on the rotating shaft 7, making it easy to remove the damaged straightening wheel 10, replace it with a new straightening wheel 10, and then install it in reverse, extending the service life of the device.
