Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy pipeline processing technology, and in particular to a water conservancy pipeline rolling device. Background Technology
[0002] A pipe rolling device is a specialized piece of equipment used for pipe processing. It employs rolling technology to shape, enlarge or reduce the diameter of pipes, and perform other processing operations.
[0003] The rolling mill is the core component of the unit, consisting of multiple rolling mills arranged in a specific pattern. These mills process the pipe through rotation and extrusion. The rolling mills are typically made of wear-resistant, high-strength materials to ensure their stability and durability over long-term use.
[0004] In the existing technology, due to the limitations of the transmission mechanism, the rolling wheels are fixedly installed and the height difference between the upper and lower wheels is fixed. This means that such rolling devices can only be adapted to rolling pipes of a single size. When adapting to pipes of different sizes, new complete sets of equipment need to be replaced, resulting in poor production efficiency and flexibility. Utility Model Content
[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0006] Therefore, one objective of this utility model is to provide a water conservancy pipeline rolling device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0007] To achieve the above objectives, one embodiment of the present invention provides a hydraulic pipeline rolling device, including a frame, a motor, and a reducer. The motor and the reducer are installed on the inner side of the frame. The output end of the motor enters the reducer, and a chain is movably connected to the end of the output end of the reducer. The inner side of the other end of the chain is movably connected to a main shaft, and a main gear is fixedly connected to the outer surface of the main shaft. Secondary gears are movably connected to both sides of the main gear. Several bearings are installed on the top of the frame, and the main shaft is installed in the bearings; The main shaft is mounted on the front of the auxiliary gear, and a rolling wheel is fixedly connected to the end of the main shaft of the auxiliary gear. The rolling wheel has a concave rolling surface. A frame is fixedly connected to the top surface of the frame, a rail is fixedly connected to the inner side of the frame, a screw is threadedly connected to the top surface of the frame, a slide is movably connected to the bottom end of the screw, and the slide is movably connected to the rail. A rolling wheel is movably connected to the front of the slide, a synchronous wheel is movably connected to the back of the slide, a synchronous wheel is fixedly connected to the end of the main gear spindle, and a synchronous belt is movably connected to the outer surface of the synchronous wheel.
[0008] Preferably, in any of the above embodiments, the motor is located on one side of the reducer, and the output end of the reducer is perpendicular to the output end of the motor.
[0009] The above technical solution is adopted: This device is specifically used for the rolling of water conservancy pipelines and uses a single motor as the power source.
[0010] This device can be divided into four parts: The first part, the power unit, consists of a motor and a speed reducer; The second part, the transmission part, consists of a chain, main shaft, main gear, auxiliary gear, bearings, synchronous pulleys and synchronous belts. The reducer transmits power to the main gear through the chain, and the main gear drives the auxiliary gears on both sides to rotate. The third part, the rolling section, consists of three rolling rollers arranged in a triangular pattern, with the height of the middle rolling roller being adjustable; The fourth part, the height adjustment section, consists of a frame, rails, screws, and slides.
[0011] Preferably, in any of the above solutions, both the output end of the reducer and the end of the main gear shaft are fixedly connected to a sprocket adapted to the chain.
[0012] The above technical solution involves rotating the screw forward, causing the slide to move downward along the track, thus lowering the height of the corresponding rolling roller; rotating the screw backward, causing the slide to move upward along the track, thus raising the height of the corresponding rolling roller. The core advantage of this device is that the entire rolling roller assembly can flexibly adapt to the rolling requirements of steel pipes with different diameters and wall thicknesses. Without replacing the entire roller assembly or making complex adjustments, only the height of the uppermost rolling roller needs to be adjusted to easily achieve the rolling of steel pipes of different specifications, greatly improving production efficiency and flexibility.
[0013] By adjusting the height of the uppermost rolling mill, the distribution of rolling force on the steel pipe can be optimized. This helps reduce stress concentration and deformation during rolling, improving the forming quality and surface finish of the steel pipe. Simultaneously, a reasonable distribution of rolling force can also reduce wear on the rolling mill, extending its service life.
[0014] After adjusting the height of the rolling mill, a timing belt of the corresponding length needs to be installed on the timing pulley.
[0015] Preferably, in any of the above schemes, the main shaft of the main gear is shorter than the other main shafts, the main gear is located between the two auxiliary gears, and the main gear and auxiliary gears have the same diameter.
[0016] Preferably, according to any of the above solutions, there are three rolling wheels in total, which are distributed in a "pin" shape, and the height of the rolling wheel corresponding to the main gear is adjustable.
[0017] Preferably, according to any of the above solutions, the track is installed vertically, and a handle is fixedly connected to the top end of the screw rod.
[0018] With the above technical solution: The three rolling wheels can be driven to rotate by a single motor, a reducer, a chain, a main shaft, a main gear, a sub-gear, a bearing, a synchronous pulley and a synchronous belt, without any extra power source, which is more energy-efficient.
[0019] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows: For this water conservancy pipe rolling device, through the cooperative setting of the frame, the track, the screw rod, the sliding seat, the synchronous pulley and the synchronous belt, when the screw rod is rotated forward, the sliding seat moves down along the track, and the height of the corresponding rolling wheel is lowered; when the screw rod is rotated reversely, the sliding seat moves up along the track, and the height of the corresponding rolling wheel is raised. The entire rolling wheel group can flexibly adapt to the rolling requirements of steel pipes with different diameters and wall thicknesses. There is no need to replace the entire wheel group or perform complex adjustments. Only by adjusting the height of the uppermost rolling wheel can the rolling of steel pipes of different specifications be easily achieved, greatly improving the production efficiency and flexibility.
[0020] By adjusting the height of the uppermost rolling wheel, the distribution of the rolling force on the steel pipe can be optimized. This helps to reduce stress concentration and deformation during the rolling process, improve the forming quality and surface finish of the steel pipe. At the same time, a reasonable distribution of the rolling force can also reduce the wear of the rolling wheel and extend its service life.

The two sides of the main gear 6 are movably connected to the auxiliary gear 7. Several bearings 8 are installed on the top of the frame 1, and the main shaft 5 is installed in the bearings 8; The main shaft 5 is mounted on the front of the auxiliary gear 7, and the ends of the main shaft 5 of the auxiliary gear 7 are all fixedly connected to rolling wheels 9, which have concave rolling surfaces. A frame 10 is fixedly connected to the top surface of the frame 1, a rail 11 is fixedly connected to the inner side of the frame 10, a screw 12 is threadedly connected to the top surface of the frame 10, and a slide 13 is movably connected to the bottom end of the screw 12. The slide 13 is movably connected to the rail 11. The front of the slide 13 is movably connected to the rolling wheel 9, the back of the slide 13 is movably connected to the synchronous wheel 14, the end of the main shaft 5 of the main gear 6 is fixedly connected to the synchronous wheel 14, and the outer surface of the synchronous wheel 14 is movably connected to the synchronous belt 15.
[0027] Embodiment 1: The motor 2 is located on one side of the speed reducer 3, and the output end of the speed reducer 3 is perpendicular to the output end of the motor 2. This device is specifically used for the rolling of water pipelines and uses a single motor 2 as the power source.
[0028] This device can be divided into four parts: The first part is the power part, which consists of the motor 2 and the speed reducer 3; The second part is the transmission part, which consists of a chain 4, a main shaft 5, a main gear 6, a sub-gear 7, a bearing 8, a synchronous pulley 14, and a synchronous belt 15. The power from the speed reducer 3 is transmitted to the main gear 6 through the chain 4, and the main gear 6 drives the sub-gears 7 on both sides to rotate; The third part is the rolling part, which consists of three rolling wheels 9 distributed in a triangular formation. Among them, the height of the middle rolling wheel 9 is adjustable; The fourth part is the height adjustment part, which consists of a frame 10, a track 11, a screw 12, and a sliding seat 13. At the ends of the output of the speed reducer 3 and the main shaft 5 of the main gear 6, sprockets adapted to the chain 4 are fixedly connected.
[0029] Embodiment 2: The main shaft 5 of the main gear 6 is shorter than the other main shafts 5. The main gear 6 is located between the two sub-gears 7, and the main gear 6 and the sub-gears 7 have the same diameter. There are three rolling wheels 9 in total and they are distributed in a triangular formation. The height of the rolling wheel 9 corresponding to the main gear 6 is adjustable. The track 11 is installed vertically, and a handle is fixedly connected to the top of the screw 12. The three rolling wheels 9 can be driven to rotate by a single motor 2, a speed reducer 3, in cooperation with a chain 4, a main shaft 5, a main gear 6, a sub-gear 7, a bearing 8, a synchronous pulley 14, and a synchronous belt 15, without the need for an additional power source, which is more energy-efficient.
[0030] The working principle of the present utility model is as follows: S1. The power from the speed reducer 3 is transmitted to the main gear 6 through the chain 4, and the main gear 6 drives the sub-gears 7 on both sides to rotate. The synchronous pulleys 14 are linked through the synchronous belt 15, and the three rolling wheels 9 form a rolling wheel group. When the rolling wheel 9 contacts the pipeline to be rolled, due to the rotation of the rolling wheel 9, a rolling force on the pipeline is generated. This rolling force is transmitted to the pipeline through the contact surface of the rolling wheel 9, causing the pipeline to undergo plastic deformation under the action of the rolling wheel 9.
[0031] S2. Rotate the screw 12 clockwise, and the sliding seat 13 moves downward along the track 11, lowering the height of the corresponding rolling wheel 9. Rotate the screw 12 counterclockwise, and the sliding seat 13 moves upward along the track 11, raising the height of the corresponding rolling wheel 9. For the rolling wheel 9 after height adjustment, a synchronous belt 15 of the corresponding length needs to be selected and installed on the synchronous pulley 14.
[0032] After the pipeline is subjected to the continuous and uniform rolling force exerted by the rolling wheels, the cross-sectional shape of the pipeline gradually changes.
[0033] Compared with the prior art, the present invention has the following advantages: This hydraulic pipeline rolling device, through the coordinated arrangement of a frame 10, track 11, screw 12, slide 13, synchronous pulley 14, and synchronous belt 15, allows the following operation: When the screw 12 rotates forward, the slide 13 moves downward along the track 11, lowering the height of the corresponding rolling roller 9; conversely, when the screw 12 rotates backward, the slide 13 moves upward along the track 11, raising the height of the corresponding rolling roller 9. The core advantage of this device is that the entire set of 9 rolling rollers can flexibly adapt to the rolling requirements of steel pipes with different diameters and wall thicknesses. Without replacing the entire roller set or making complex adjustments, only the height of the uppermost rolling roller 9 needs to be adjusted to easily achieve the rolling of steel pipes of different specifications, greatly improving production efficiency and flexibility.
[0034] By adjusting the height of the uppermost rolling roller 9, the distribution of rolling force on the steel pipe can be optimized. This helps reduce stress concentration and deformation during the rolling process, improving the forming quality and surface finish of the steel pipe. Simultaneously, a reasonable distribution of rolling force can also reduce wear on the rolling rollers and extend their service life.
