Description

Technical Field

[0001] This utility model relates to the field of insulation pipe threading technology, specifically a rolling insulation pipe threading machine. Background Technology

[0002] Pipe threading machines, also known as cable threading machines, are commonly referred to as cable threading machines. With increasingly fierce market competition, reducing production costs, improving production efficiency, and maximizing profits have become the focus of work for various construction units and enterprises.

[0003] For example, the rolling insulated pipe threading machine with announcement number "CN211053034U" uses a mobile pipe-mounting trolley at one end of the threading support to easily move the outer pipe and avoid damage during transport, reducing the labor intensity of operators and improving the stability of the threading process. Simultaneously, the trolley is automatically driven by a sprocket to complete the threading process, greatly improving efficiency. However, this rolling insulated pipe threading machine uses two support plates to limit the outer pipe, but these plates only support the outer pipe; the outer pipe can still move normally. When inserting the inner pipe into the outer pipe, the outer pipe is prone to shifting, requiring workers to fix it in place to ensure a stable insertion. This consumes worker energy and increases labor costs. Furthermore, while the mobile pipe-mounting trolley moves the outer pipe to the designated position, workers still need to align the centers of the outer and inner pipes, which takes considerable time and reduces overall efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the existing rolling insulated pipe threading machine. In this machine, two support plates limit the outer pipe, but the outer pipe can still move freely. When inserting the inner pipe into the outer pipe, the outer pipe easily shifts, requiring workers to fix it in place to ensure a stable insertion. This consumes considerable physical labor and increases manual labor costs. Furthermore, while the existing rolling insulated pipe threading machine uses a mobile pipe-loading trolley to move the outer pipe to a designated position, workers still need to align the centers of the outer and inner pipes, which takes considerable time and reduces work efficiency. Therefore, this invention proposes a rolling insulated pipe threading machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a rolling insulated pipe threading machine, including a base plate, the upper end of which is attached to a trolley. Cylinders are symmetrically fixedly connected to the middle of the upper end of the trolley. Vertical rods are fixedly connected to the four corners of the upper end of the trolley. Horizontal plates are fixedly connected to the output ends of the cylinders. The inner walls of the two horizontal plates are slidably connected to the vertical rods. Two first outer shells are fixedly connected to the inner sides of the two horizontal plates. Each of the first outer shells is equipped with a clamping mechanism inside.

[0007] Preferably, a housing is fixedly connected to the upper right side of the base plate, a second outer shell is fixedly connected to the outer wall of the housing, a positioning mechanism is provided inside the second outer shell, and a first servo motor is fixedly connected to the upper part of the outer wall of the housing.

[0008] Preferably, the clamping mechanism includes a second servo motor, the output shaft of the second servo motor is fixedly connected to a turntable, the inner wall of the turntable is machined with two sliding grooves, the inner walls of the sliding grooves are slidably connected to sliders, the outer walls of the two sliders are respectively slidably connected to a sliding frame, and the lower end of the outer wall of the sliding frame is fixedly connected to a clamping block.

[0009] Preferably, the outer wall of the second servo motor is fixedly connected to the first housing, and the inner wall of the slide frame is slidably connected to the straight rod machined in the first housing.

[0010] Preferably, the output shaft of the first servo motor is fixedly connected to a left toothed pulley, the left toothed pulley meshes with a toothed belt, and the toothed belt meshes with a right toothed pulley.

[0011] Preferably, the positioning mechanism includes a third servo motor, the output shaft of which is fixedly connected to a worm gear, the worm gear meshing with a worm wheel, the rotating shaft of the worm wheel being fixedly connected to a gear, the gear meshing with a rack, the rotating shaft of the gear being rotatably connected to the second housing via a bearing, the protrusion of the rack being slidably connected to the second housing, and the end of the rack engaging with a groove machined on the positioning rod.

[0012] Preferably, the outer wall of the third servo motor is fixedly connected to the second housing, and the left end of the positioning rod is fixedly connected to the right end of the trolley.

[0013] Preferably, the rotating shafts of the toothed pulleys are rotatably connected to the housing via bearings, the upper end of the outer wall of the toothed belt penetrates the housing, and an auxiliary roller is installed on the upper end of the outer wall of the housing.

[0014] The present invention proposes a rolling insulated pipe threading machine, which has the following advantages: Through the cooperation of the clamping mechanism and the cylinder, the output shaft of the second servo motor rotates forward, driving the turntable to rotate, thereby driving the slider to move inward along the groove machined on the turntable. The slider moves inward, driving the sliding frame to move. The sliding frame is limited by the first outer shell. The movement of the sliding frame drives the clamping block to move. When the inner wall of the clamping block is pressed against the outer pipe, the second servo motor can be stopped. The second servo motor is a servo motor with self-locking, which can fix the clamping block to a fixed position, thereby fixing the outer pipe. It can clamp the outer pipe and ensure that the outer pipe will not move when the inner pipe is threaded. It eliminates the need for workers to fix the outer pipe, thereby reducing the physical exertion of workers and reducing manual labor.

[0015] Through the cooperation of the positioning mechanism and the housing, the output shaft of the third servo motor rotates forward, driving the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel rotates, driving the gear to rotate, which in turn drives the rack to move. Limited by the second housing, the rack moves horizontally. The rack end is trapezoidal, making it easier for the rack to enter the groove machined in the positioning rod. Once the rack enters the groove machined in the positioning rod, the third servo motor is turned off. After the rack enters the positioning rod, it can lock the positioning rod in this position, thereby locking the trolley in this position. This achieves the positioning of the trolley. The positioning mechanism can quickly position the trolley in a designated position, allowing the outer tube and the inner tube to be quickly aligned. This reduces the alignment time required by the operator and improves work efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] See attached document Figure 1-6 :

[0025] In this embodiment, a rolling insulation pipe threading machine includes a base plate 1. The upper end of the base plate 1 is attached to a trolley 2. A cylinder 3 is symmetrically fixedly connected to the middle of the upper end of the trolley 2. Vertical rods 4 are fixedly connected to the four corners of the upper end of the trolley 2. A horizontal plate 5 is fixedly connected to the output end of the cylinder 3. The output end of the cylinder 3 extends and retracts to drive the horizontal plate 5 to move. The horizontal plate 5 can only move vertically due to the limitation of the vertical rods 4. The inner walls on both sides of the two horizontal plates 5 are slidably connected to the vertical rods 4. Two first outer shells 7 are fixedly connected to the inner side of the two horizontal plates 5. The first outer shell 7 is provided with a clamping mechanism 6 inside. A box 10 is fixedly connected to the upper right side of the base plate 1. A second outer shell 8 is fixedly connected to the outer wall of the box 10.

[0026] The second outer casing 8 has a positioning mechanism 9 inside. A first servo motor 11 is fixedly connected to the upper part of the outer wall of the housing 10. The output shaft of the first servo motor 11 is fixedly connected to a left toothed pulley 12. The left toothed pulley 12 meshes with a toothed belt 13. The rotation of the output shaft of the first servo motor 11 drives the left toothed pulley 12 to rotate, thereby driving the toothed belt 13 to rotate. The rotation of the toothed belt 13 drives the right toothed pulley 12 to rotate. The toothed belt 13 meshes with the right toothed pulley 12. The rotation shafts of the toothed pulleys 12 are all rotatably connected to the housing 10 through bearings. The upper end of the outer wall of the toothed belt 13 passes through the housing 10. The rotation of the toothed belt 13 can drive the inner tube on the toothed belt 13 to move. An auxiliary roller 14 is installed on the upper end of the outer wall of the housing 10. The auxiliary roller 14 plays an auxiliary role in moving and rotating the inner tube.

[0027] See attached document Figure 1-2 And 4-5:

[0028] The clamping mechanism 6 includes a second servo motor 601. The output shaft of the second servo motor 601 is fixedly connected to a turntable 602. The rotation of the output shaft of the second servo motor 601 causes the turntable 602 to rotate. The inner wall of the turntable 602 is machined with two sliding grooves 603. The inner wall of each sliding groove 603 is slidably connected to a slider 604. The slider 604 has protrusions that can hold the slider 604 in place to prevent it from falling out of the sliding grooves 603.

[0029] The rotation of turntable 602 drives the rotation of two slide grooves 603, thereby moving two sliders 604. The outer walls of the two sliders 604 are slidably connected to a slide frame 605. The movement of the two sliders 604 drives the slide frame 605 to move. The lower end of the outer wall of the slide frame 605 is fixedly connected to a clamping block 606. The slide frame 605 drives the clamping block 606 to move. The outer wall of the second servo motor 601 is fixedly connected to the first housing 7. The inner wall of the slide frame 605 is slidably connected to the straight rod processed in the first housing 7. The first housing 7 limits the slide frame 605, thereby allowing the slide frame 605 to move horizontally.

[0030] See attached document Figure 1-3 :

[0031] The positioning mechanism 9 includes a third servo motor 901. The output shaft of the third servo motor 901 is fixedly connected to a worm gear 902. The rotation of the output shaft of the second servo motor 901 drives the worm gear 902 to rotate. The worm gear 902 meshes with a worm wheel 903. The rotation of the worm gear 902 drives the worm wheel 903 to rotate. The rotating shaft of the worm wheel 903 is fixedly connected to a gear 904. The gear 904 meshes with a rack 905. The rotation of the worm wheel 903 drives the gear 904 to rotate, thereby driving the rack 905 to move. The rotating shaft of the gear 904 is rotatably connected to the second housing 8 through a bearing. The protrusion of the rack 905 is slidably connected to the second housing 8. The rack 905 is limited by the second housing 8 and can only move horizontally.

[0032] The end of the rack 905 engages with the groove machined on the positioning rod 906. The pointed end of the rack 905 makes it easier to insert into the groove on the positioning rod 906. When the rack 905 enters the positioning rod 906, it can lock the positioning rod 906 in place, thus fixing the positioning rod 906 in this position. The outer wall of the third servo motor 901 is fixedly connected to the second outer shell 8. The left end of the positioning rod 906 is fixedly connected to the right end of the trolley 2. The positioning rod 906 positions the trolley 2. The positioning hole surface machined in the housing 10 has an angle, which makes it easier for the positioning rod 905 to enter the housing 10.

[0033] Working principle:

[0034] When it is necessary for staff to insert the inner tube into the insulated pipe.

[0035] Preparation:

[0036] The worker moves the trolley 2 to the location where the outer tube is placed, and then inserts the outer tube between the two pairs of clamps 606 (e.g., Figure 4 Then, the two second servo motors 601 are started. The output shaft of the second servo motor 601 rotates forward, driving the turntable 602 to rotate, thereby driving the slider 604 to move inward along the groove 603 machined on the turntable 602. The slider 604 moves inward, driving the sliding frame 605 to move. The sliding frame 605 is limited by the first outer shell 7. The sliding frame 605 moves inward, driving the clamping block 606 to move. When the inner wall of the clamping block 606 is pressed against the outer tube, the second servo motor 601 is stopped. The second servo motor 601 is a servo motor with self-locking, which can fix the clamping block 606 to a fixed position, so as to fix the outer tube.

[0037] Then move car 2 again (as shown in the image). Figure 2 The movement of the trolley 2 moves the positioning rod 906, which then enters the positioning hole machined in the housing 10. Because the outer wall of the positioning hole in the housing 10 is funnel-shaped, it facilitates the entry of the positioning rod 906. Once the right side of the trolley 2 is flush with the housing 10, the third servo motor 901 is activated. The output shaft of the third servo motor 901 rotates clockwise, causing the worm gear 902 to rotate, which in turn drives the worm wheel 903 to rotate. The worm wheel 903 rotates, driving the gear 904 to rotate, which in turn drives the rack 905 to move. The rack 905 is limited by the second housing 8, causing it to move horizontally. The end of the rack 905 is trapezoidal, making it easier for it to enter the groove machined in the positioning rod 906. Once the rack 905 enters the groove, the third servo motor 901 is turned off. After the rack 905 enters the positioning rod 906, the positioning rod 906 is locked in this position, thus locking the trolley 2 in this position (e.g., ...). Figure 3 This achieves the positioning of the car 2, and then the cylinder 3 is started (e.g. Figure 2 The output end of cylinder 3 extends and retracts, causing the horizontal plate 5 to move up and down. The horizontal plate 5 moves up and down, causing the first outer shell 7 to move up and down, thereby causing the clamping mechanism 8 to move up and down. The clamping mechanism 8 moves up and down, causing the outer tube to move up and down. The operator adjusts the height of the outer tube according to the center of the inner tube. When the center of the outer tube is aligned with the center of the inner tube, the cylinder is closed.

[0038] Pipe threading process:

[0039] Start the first servo motor 11 (e.g.) Figure 6 The output shaft of the first servo motor 11 rotates, driving the left toothed pulley 12 to rotate, which in turn drives the toothed belt 13 to rotate. The rotation of the toothed belt 13 then drives the right toothed pulley 12 to rotate, causing the inner tube to move along the toothed belt 13 towards the insulation tube. Once the inner tube enters the insulation tube, the second servo motor 601 is re-controlled (e.g., ...). Figure 4The output shaft of the second servo motor 601 reverses, causing the turntable 602 to reverse, which in turn causes the slider 604 to move outward. The slider 604 moves outward, causing the sliding frame 605 to move outward, which in turn causes the clamping block 606 to move outward. The clamping block 606 moves outward and disengages from the outer wall of the insulation tube with the inner tube attached. The operator can then remove the insulation tube with the inner tube attached and turn off all power.
