Description

Technical Field

[0001] This utility model relates to the field of hydraulic steel pipe assembly technology, and in particular to a rapid drying device for hydraulic steel pipe assembly. Background Technology

[0002] A hydraulic steel pipe assembly is a component used in hydraulic systems, consisting of formed steel pipes and fittings. The formed steel pipes are usually made of cold-drawn or cold-rolled precision seamless steel pipes, which have high dimensional accuracy and good surface finish, can withstand high pressure and are leak-free. During the production process, the hydraulic steel pipe assembly needs to be dried to remove moisture and destroy the conditions for corrosion reaction.

[0003] However, when drying hydraulic steel pipe assemblies, they are usually placed directly into a drying oven. This can prevent some parts of the hydraulic steel pipe assembly from fully contacting the hot air, resulting in uneven drying. Consequently, some parts may not be able to completely remove moisture, affecting the drying effect. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid drying device for hydraulic steel pipe assemblies. This device is equipped with a reciprocating screw, a sliding plate, and a nozzle, which causes the sliding plate to move back and forth with the nozzle. This allows hot air to be sprayed evenly onto the surface of the hydraulic steel pipe assembly, ensuring that the entire hydraulic steel pipe assembly is dried quickly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid drying device for hydraulic steel pipe assemblies includes a drying chamber. Two door panels are hinged to the outer wall of the drying chamber. A sliding frame is slidably connected to the inner bottom of the drying chamber. A bidirectional threaded rod is rotatably connected between the inner walls of the two sides of the sliding frame. Each threaded end of the bidirectional threaded rod is threadedly connected to a movable frame. Two first electric telescopic rods are installed on the inner top of each of the two movable frames. The telescopic ends of each pair of cooperating first electric telescopic rods are jointly and fixedly connected to a lifting plate. Rotary shafts are rotatably connected to opposite sides of the two lifting plates. Rotary plates are fixedly connected to the outer walls of the two rotating shafts. A hydraulic cylinder is installed on the inner wall of the drying chamber. The other end of the hydraulic cylinder is fixedly connected to the sliding frame. Fixed plates are fixedly connected to both inner walls of the drying chamber. The two fixed plates are hollow inside and have through holes on opposite sides. A reciprocating screw is rotatably connected between the two inner walls of the drying chamber. A sliding plate is threaded onto the reciprocating screw. The sliding plate is hollow inside. Multiple nozzles are fixedly connected to the lower end of the sliding plate. A fan is installed at the upper end of the drying chamber. The air inlet of the fan is connected to a branch pipe. The other end of the branch pipe is connected to the interior of the two fixed plates respectively. The air outlet of the fan is connected to the interior of the sliding plate. Clamping mechanisms are provided on both rotating plates.

[0007] Preferably, a first motor is installed on the outer wall of the sliding frame, and the end of the output shaft of the first motor passes through the sliding frame and is fixedly connected to one end of a bidirectional threaded rod.

[0008] Preferably, a second motor is installed on the side wall of one of the lifting plates, and the output shaft of the second motor passes through one of the lifting plates and is fixedly connected to one end of one of the rotating shafts.

[0009] Preferably, both clamping mechanisms include adjustment slots formed in corresponding rotating plates, rotating rods are rotatably connected to the inner walls of both adjustment slots, gears are fixedly connected to the outer walls of both rotating rods, second electric telescopic rods are installed on the inner walls of both adjustment slots, moving blocks are fixedly connected to the telescopic ends of both second electric telescopic rods, racks are fixedly connected to one end of both moving blocks, and both racks mesh with corresponding gears.

[0010] Preferably, the opposite ends of the two rotating rods extend to the outside and are fixedly connected to rotating disks. Multiple movable plates are slidably connected to the outer side walls of the two rotating plates. A movable rod is fixedly connected to the other side wall of each movable plate.

[0011] Preferably, a third motor is installed on the outer wall of the drying chamber, and the output shaft of the third motor extends into the interior of the drying chamber and is fixedly connected to one end of a reciprocating lead screw.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The structure includes a reciprocating screw, a sliding plate, and nozzles, which allows the sliding plate to move back and forth with multiple nozzles. This ensures that hot air is evenly sprayed onto the surface of the hydraulic steel pipe assembly, preventing localized overheating or insufficient drying. Furthermore, the fan draws hot air from the drying chamber through a branch pipe and then sends it into the sliding plate before it is sprayed out through the nozzles, forming a relatively closed hot air circulation system. This reduces heat loss and improves drying efficiency.

[0014] 2. The structure includes a two-way threaded rod and a movable frame, which allows for flexible adjustment of the distance between the two movable frames according to the length of the hydraulic steel pipe assembly. It also allows the clamping mechanism to be moved to the appropriate position according to the specifications of the hydraulic steel pipe assembly. With the cooperation of gears, racks, and clamping plates, multiple clamping plates can clamp the hydraulic steel pipe assembly from different directions, ensuring that the hydraulic steel pipe assembly remains stable during the drying process and does not shake or shift.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-7 A rapid drying device for hydraulic steel pipe assemblies includes a drying chamber 1. To heat the air inside the drying chamber 1, multiple heating tubes (not shown in the figure) are installed on the inner wall of the drying chamber 1. Two door panels 2 are hinged to the outer wall of the drying chamber 1. A sliding frame 3 is slidably connected to the inner bottom of the drying chamber 1. A bidirectional threaded rod 4 is rotatably connected between the inner walls of the two sides of the sliding frame 3. A movable frame 5 is threaded to both threaded ends of the bidirectional threaded rod 4. A first motor 6, which is a servo motor, is installed on the outer wall of the sliding frame 3. The output shaft of the first motor 6 passes through the sliding frame 3 and is fixedly connected to one end of the bidirectional threaded rod 4. By adjusting the distance between the two moving frames 5, it can accommodate hydraulic steel pipe assemblies of different lengths. Two first electric telescopic rods 7 are installed on the inner top of each of the two moving frames 5. The telescopic ends of each pair of cooperating first electric telescopic rods 7 are fixedly connected to a lifting plate 8. Rotating shafts 9 are rotatably connected to the opposite sides of the two lifting plates 8. Rotating plates 10 are fixedly connected to the outer walls of the two rotating shafts 9. A second motor 11 is installed on the side wall of one of the lifting plates 8. The second motor 11 is a servo motor. The output shaft of the second motor 11 passes through one of the lifting plates 8 and is fixedly connected to one end of one of the rotating shafts 9.

[0025] Both rotating plates 10 are equipped with clamping mechanisms. The height of the lifting plate 8 can be flexibly adjusted by the first electric telescopic rod 7, thereby adjusting the height of the rotating plates 10 and the clamping mechanisms to accommodate hydraulic steel pipe assemblies of different specifications. The second motor 11 drives the rotating shaft 9 and the rotating plates 10 to rotate, allowing for multi-angle adjustment of the hydraulic steel pipe assembly, which is beneficial for thorough drying and also facilitates clamping operations at different angles. Both clamping mechanisms include adjustment grooves 12 formed in the corresponding rotating plates 10. The inner walls of both adjustment grooves 12 are rotatably connected to rotating rods 13. Gears 14 are fixedly connected to the outer wall of the moving rod 13. Second electric telescopic rods 15 are installed on the inner walls of the two adjusting grooves 12. Moving blocks 16 are fixedly connected to the telescopic ends of the two second electric telescopic rods 15. A rack 17 is fixedly connected to one end of the two moving blocks 16. The two racks 17 mesh with the corresponding gears 14. The opposite ends of the two rotating rods 13 extend to the outside and are fixedly connected to a rotating disk 18. Multiple moving plates 19 are slidably connected to the outer walls of the two rotating plates 10. A moving rod 20 is fixedly connected to the other side wall of each moving plate 19.

[0026] Each of the two rotating disks 18 has multiple arc-shaped grooves 21. Each moving rod 20 cooperates with the corresponding arc-shaped groove 21. A clamping plate 22 is fixedly connected to the other side wall of each moving plate 19. The second electric telescopic rod 15 pushes the moving block 16 and the rack 17, which in turn drives the gear 14 and the rotating rod 13 to rotate, thereby causing the rotating disk 18 to rotate. Through the cooperation of the arc-shaped grooves 21 and the moving rods 20, the moving plates 19 and the clamping plates 22 can be driven to move, realizing the clamping and loosening of the hydraulic steel pipe assembly. The multiple clamping plates 22 evenly clamp the steel pipe assembly. The pipe is clamped to ensure that the steel pipe is stable and does not shake during the drying process. A hydraulic cylinder 23 is installed on the inner wall of the drying chamber 1. The other end of the hydraulic cylinder 23 is fixedly connected to the sliding frame 3. The hydraulic cylinder 23 can push the sliding frame 3 to slide at the bottom of the drying chamber 1, so that the entire steel pipe clamping device can move inside the drying chamber 1, making it convenient to move the steel pipe assembly to a suitable drying position, and also making it convenient to load and unload the steel pipe. Fixing plates 24 are fixedly connected to the inner walls on both sides of the drying chamber 1. The two fixing plates 24 are hollow inside, and through holes are opened on opposite sides.

[0027] The drying chamber 1 is rotatably connected to the inner walls on both sides by a reciprocating screw 25. A sliding plate 26 is threaded onto the reciprocating screw 25. The sliding plate 26 is hollow inside, and multiple nozzles 27 are fixedly connected to the lower end of the sliding plate 26. A third motor 28, which is a servo motor, is installed on the outer wall of the drying chamber 1. By rotating the reciprocating screw 25, the sliding plate 26 moves back and forth, allowing the nozzles 27 to spray hot air evenly onto the hydraulic steel pipe assembly, thereby improving drying efficiency. The output shaft of the third motor 28 extends into the interior of the drying chamber 1 and is fixedly connected to one end of the reciprocating screw 25. A fan 29 is installed at the upper end of the drying chamber 1. The air inlet of the fan 29 is connected to a branch pipe 30, and the other end of the branch pipe 30 is connected to the interior of two fixed plates 24. The air outlet of the fan 29 is connected to the interior of the sliding plate 26. The air outlet pipe connected to the air outlet of the fan 29 is a flexible hose. This forms a relatively closed hot air circulation system, reducing heat loss and improving energy utilization efficiency.

[0028] In this utility model, when in use, the two door panels 2 are opened, and the extension and retraction of the hydraulic cylinder 23 are controlled to push the sliding frame 3 to slide at the bottom of the drying box 1, so as to adjust the sliding frame 3 to a suitable position for convenient subsequent operation;

[0029] Start the first motor 6 to rotate the bidirectional threaded rod 4, which in turn causes the two moving frames 5 to move relative to or away from each other to accommodate hydraulic steel pipe assemblies of different lengths. After adjusting the distance between the two moving frames 5, start the first electric telescopic rod 7 to drive the lifting plate 8 to move up and down, and adjust the rotating plate 10 and the clamping mechanism on it to a suitable height so that the hydraulic steel pipe assembly is in a suitable position between the two rotating plates 10 for easy clamping.

[0030] Activate the second electric telescopic rod 15 to push the moving block 16 to move. The moving block 16 drives the rack 17 to move, causing the gear 14 meshing with the rack 17 to rotate, which in turn causes the rotating rod 13 to rotate. When the rotating rod 13 rotates, it will drive the rotating disk 18 to rotate. The arc groove 21 cooperates with the moving rod 20. Therefore, as the rotating disk 18 rotates, the arc groove 21 will push the moving rod 20, causing the moving plate 19 to slide on the rotating plate 10, which in turn drives the clamping plate 22 to move. In this way, multiple clamping plates 22 clamp and fix the hydraulic steel pipe assembly from different directions to ensure that the hydraulic steel pipe assembly is stable and does not shake during the drying process.

[0031] When the fan 29 is started, the hot air inside the drying chamber 1 is drawn into the two branch pipes 30 through the two fixed plates 24, and then enters the sliding plate 26 through the air outlet of the fan 29, and is sprayed out through multiple nozzles 27. At the same time, the third motor 28 can be started to drive the reciprocating screw 25 to rotate, thereby causing the sliding plate 26 to move back and forth. The multiple nozzles 27 will spray hot air evenly on the surface of the hydraulic steel pipe assembly as the sliding plate 26 moves back and forth, so as to achieve rapid drying of the hydraulic steel pipe assembly. During the drying process, the second motor 11 can also be started to drive one of the rotating shafts 9 to rotate, thereby causing the rotating plate 10 to rotate. The other rotating plate 10 will also rotate synchronously through the connection of the hydraulic steel pipe assembly, so that the hydraulic steel pipe assembly can be fully contacted with the hot air at all angles. Through this heat circulation method, the hot air can be evenly distributed in the drying chamber 1, ensuring the consistency and efficiency of the drying effect.

[0032] After drying is complete, reverse the clamping steps described above to loosen the hydraulic steel pipe assembly by clamping plate 22. Then, start hydraulic cylinder 23 to move sliding frame 3 to a suitable position, open door panel 2, and remove the dried hydraulic steel pipe assembly.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
