[0001] This utility model belongs to the field of energy storage tube processing technology, specifically relating to an energy storage tube ring cutting device. Background Technology

[0002] As the global energy structure shifts towards cleaner and lower-carbon energy, large-scale energy storage technology has become a key core technology for balancing grid load and promoting the consumption of renewable energy. Among various energy storage technologies, those that use large tubular structures as core energy storage components, such as compressed air energy storage (CAES) pipelines, liquid storage pipes for large flow batteries, and heat exchange tubes for certain innovative thermal energy storage systems, are showing broad application prospects.

[0003] These energy storage tubes are typically made of high-performance composite materials (such as carbon fiber composites and fiberglass) or high-strength alloy steel, and are characterized by large diameters (several meters to over ten meters), thick walls, and high structural strength. Circumferential cutting is a crucial process throughout their entire lifecycle.

[0004] However, existing equipment relies primarily on workers to move the pipes to the appropriate length for cutting when processing energy storage pipes, which can lead to dimensional errors due to manual operation. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model achieves precise control of the pipe conveying distance by setting up a pipe-length-fixed-length pushing assembly consisting of a lead screw, drive motor, and linkage plate, combined with an initial slot-type photoelectric switch and an adjustable limit slot-type photoelectric switch.

[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] Please see Figures 1-5 This utility model provides an energy storage pipe ring cutting device, including an energy storage pipe ring cutting equipment body 1, and a pipe length-limiting pushing component for limiting the pipe is provided on one side of the energy storage pipe ring cutting equipment body 1;

[0026] The pipe length-fixed push assembly includes an auxiliary support 2 set on one side of the main body 1 of the energy storage pipe ring cutting equipment. A drive motor 4 is installed inside the auxiliary support 2. The output shaft of the drive motor 4 is fixedly connected to a lead screw 5 through a coupling. A linkage plate 7 is threadedly connected to the surface of the lead screw 5 through a threaded cylinder. Connecting rods 8 are symmetrically arranged above the linkage plate 7. A drive wheel 9 is rotatably connected inside each connecting rod 8. Two positioning rails 6 are symmetrically fixedly connected to the top surface of the auxiliary support 2. The linkage plate 7 is slidably connected to the positioning rails 6 through a slider. The auxiliary support 2 is fixedly connected to the main body 1 of the energy storage pipe ring cutting equipment by bolts.

[0027] When it is necessary to transport the pipe, the drive motor 4 is connected to the power supply and started. The linkage plate 7 will move on the surface of the positioning rail 6 due to the rotation of the lead screw 5, thereby driving the drive wheel 9 to move through the connecting rod 8. When the drive wheel 9 moves, the drive wheel 9 will drive the pipe to move, thereby realizing the pushing of the pipe.

[0028] In actual operation, the staff only needs to set the starting parameters of the drive motor 4 according to the specific specifications of the pipe and the required conveying distance. For example, adjusting the speed of the drive motor 4 will change the rotation speed of the lead screw 5, which in turn affects the moving speed of the linkage plate 7 on the surface of the positioning rail 6. The moving speed of the connecting rod 8 and the drive wheel 9 will also change accordingly, ultimately achieving precise control of the pipe conveying speed.

[0029] It should be noted that in this application, the drive motor 4 is a servo motor with an encoder, and the number of rotations and rotation angle of the motor output shaft are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0030] In this utility model, an initial slot-type photoelectric switch 15 is fixedly connected to one side of the auxiliary bracket 2, a positioning slot is opened on one side of the auxiliary bracket 2, and a slider is slidably connected inside the positioning slot. A limit slot-type photoelectric switch 16 is fixedly connected to the surface of the slider, and a baffle is fixedly connected to the bottom surface of the linkage plate 7.

[0031] A dimension table 17 is fixedly connected to the side of the auxiliary bracket 2, and a pointer 18 is fixedly connected to the bottom surface of the limit slot type photoelectric switch 16. A locking screw 14 is threadedly connected to the surface of the pointer 18, and a rubber pad is fixedly connected to the end of the locking screw 14 facing the auxiliary bracket 2.

[0032] To ensure more precise positioning of the pipe, the limit slot photoelectric switch 16 moves within the positioning slot via a slider. The position of the limit slot photoelectric switch 16 is determined by the pointer 18's position on the dimension chart 17. Once the limit slot photoelectric switch 16 reaches the appropriate position, the locking screw 14 is rotated, causing the rubber pad to engage with the auxiliary bracket 2, thus positioning the limit slot photoelectric switch 16. When the linkage plate 7 moves, the baffle on the bottom of the linkage plate 7 inserts into the U-shaped slot of the limit slot photoelectric switch 16, de-energizing the drive motor 4. This ensures precise movement and positioning of the linkage plate 7, while the initial position of the slot photoelectric switch 15 remains at zero.

[0033] It should be noted that the slotted photoelectric switch in this application is model EE-SX671. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0034] It should be noted that: In this application, an annular groove is provided axially on the inner wall of the threaded cylinder, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the threaded rod at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0035] In this utility model, a positioning ring 10 is fixedly connected to the top of the connecting rod 8, and a ratchet 11 is fixedly connected to the top surface of the drive wheel 9. The axes of the ratchet 11 and the positioning ring 10 are located on the same axis. A number of ratchet teeth 12 are evenly rotated and connected to the inner wall of the positioning ring 10 through a torsion spring shaft.

[0036] The top of the auxiliary support 2 is rotatably connected to two auxiliary wheels 3 via bearing seats, and the two auxiliary wheels 3 are located on the same axis.

[0037] When the drive wheel 9 moves the pipe toward the main body 1 of the energy storage pipe circumferential cutting device, the drive wheel 9 cannot rotate due to the ratchet 12 limiting the ratchet 11. Thus, the friction between the drive wheel 9 and the pipe drives the pipe toward the main body 1 of the energy storage pipe circumferential cutting device. When the pipe needs to be moved again, the drive wheel 9 moves away from the main body 1 of the energy storage pipe circumferential cutting device. At this time, the drive wheel 9 will rotate in the opposite direction due to the friction with the pipe. At this time, the ratchet 12 will not limit the ratchet 11, so that the drive wheel 9 can only rotate in one direction.

[0038] In this utility model, a bidirectional hydraulic cylinder 13 is fixedly connected to the top surface of the linkage plate 7. The two pistons of the bidirectional hydraulic cylinder 13 are fixedly connected to two connecting rods 8 respectively. The connecting rods 8 are slidably connected to the linkage plate 7 through a slide rail.

[0039] When it is necessary to clamp the pipe using the two drive wheels 9, the bidirectional hydraulic cylinder 13 is activated, causing the piston of the bidirectional hydraulic cylinder 13 to drive the connecting rod 8 to slide on the surface of the slide rail, thereby achieving the clamping of the pipe.

[0040] It should be noted that in this application, the bidirectional hydraulic cylinder 13 is an actuator in the hydraulic system. It achieves the telescopic function by cooperating with the hydraulic system, and achieves precise control of the telescopic displacement of the hydraulic cylinder piston rod by cooperating with a magnetic switch, proximity switch or photoelectric switch. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0041] The use of this utility model involves the following steps:

[0042] S1: When it is necessary to transport the pipe, connect the drive motor 4 to the power supply and start it. The linkage plate 7 will move on the surface of the positioning rail 6 due to the rotation of the lead screw 5, thereby driving the drive wheel 9 to move through the connecting rod 8. When the drive wheel 9 moves, the drive wheel 9 will drive the pipe to move, thereby realizing the pushing of the pipe.

[0043] S2: To make the pipe movement more precise, the limit slot photoelectric switch 16 moves inside the positioning slot via a slider. The pointer 18 is positioned on the dimension table 17 to determine the position of the limit slot photoelectric switch 16. When the limit slot photoelectric switch 16 reaches the appropriate position, the locking screw 14 is rotated, and the rubber pad and auxiliary bracket 2 are in contact to achieve the position of the limit slot photoelectric switch 16. When the linkage plate 7 moves, the baffle on the bottom of the linkage plate 7 will insert into the U-shaped slot of the limit slot photoelectric switch 16 to cut off the power to the drive motor 4, thereby enabling the linkage plate 7 to move and position accurately, while the initial position of the slot photoelectric switch 15 is at the zero point.

[0044] S3: When the drive wheel 9 drives the pipe to move toward the main body 1 of the energy storage pipe ring cutting equipment, the drive wheel 9 will not be able to rotate due to the ratchet 12 limiting the ratchet 11. Thus, the friction between the drive wheel 9 and the pipe drives the pipe to move toward the main body 1 of the energy storage pipe ring cutting equipment. When the pipe needs to be moved again, the drive wheel 9 moves away from the main body 1 of the energy storage pipe ring cutting equipment. At this time, the drive wheel 9 will rotate in the opposite direction due to the friction with the pipe. At this time, the ratchet 12 will not limit the ratchet 11, so that the drive wheel 9 can only rotate in one direction.

[0045] S4: When it is necessary to clamp the pipe by means of two drive wheels 9, start the bidirectional hydraulic cylinder 13, so that the piston of the bidirectional hydraulic cylinder 13 drives the connecting rod 8 to slide on the surface of the slide rail, thereby achieving clamping of the pipe.

[0046] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0047] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
