Description

Technical Field

[0001] This invention relates to the field of power protection pipe processing technology, and more specifically, to a power protection pipe thread processing device. Background Technology

[0002] Power protection conduits are pipes used to protect power cables, providing mechanical protection, insulation, and corrosion resistance. They are suitable for various laying methods, including direct burial, duct laying, and trenchless installation. Threaded connections are a common method between adjacent power protection conduits. A connector is installed at one end of each conduit, with an internal thread inside. An external thread is installed at the end of the power protection conduit furthest from the connector. When connecting two adjacent power protection conduits, one conduit is inserted into the connector of the other via a threaded connection. When machining the threads on the power protection conduit, for internal threading of the connector at one end, a tap needs to be inserted into the connector. For external threading of the end of the power protection conduit furthest from the connector, a die needs to be fitted onto the power protection conduit.

[0003] For power protection pipes with small walls, deformation and cracking are prone to occur during the threading process, resulting in a high scrap rate. Summary of the Invention

[0004] The purpose of this invention is to provide a thread processing device for power protection pipes. The device performs thread processing in a tank filled with liquid, during which the end of the power protection pipe is immersed in the liquid. This improves the rigidity of the processed part of the power protection pipe, reduces the possibility of deformation and breakage, and thus improves the product qualification rate.

[0005] This invention is achieved through the following technical solution: a power protection pipe thread processing device, comprising: A tank containing liquid and having legs at the bottom; A thread processing mechanism is installed inside a groove. The thread processing mechanism includes a tap, a die, and a rotating assembly. The tap and the die are respectively installed on both sides of the inside of the groove. The rotating assembly is installed at the bottom of the groove and can drive the tap and the die to rotate synchronously. Two sets of feeding mechanisms are respectively set on the top two sides of the tank, used to feed the end of the power protection tube into the liquid in the tank and enable the thread processing mechanism to process threads on the power protection tube; A wiping mechanism is set at the top of the tank and located between two sets of feeding mechanisms. The wiping mechanism includes a support frame, on which a wiping rod and a drive assembly for driving the wiping rod to rotate are provided. One end of the wiping rod is provided with a wiping block and the other end is provided with a wiping sleeve. The feeding mechanism includes a fixed seat, a tilting seat, a sliding seat, and a clamping clamp. The fixed seat is fixedly mounted on the trough, the tilting seat is rotatably mounted on the fixed seat, and the fixed seat is provided with a tilting component for driving the tilting seat to tilt. The sliding seat is slidably mounted on the tilting seat, and the tilting seat is provided with a pushing component for driving the sliding seat to slide. The clamping clamp is mounted on the sliding seat and can clamp the power protection pipe.

[0006] Furthermore, when the sliding seat is in a horizontal state, the clamping tube clamps are all coaxial with the wiping rod; when the sliding seat is in a vertical state, the clamping tube clamps of one set of feeding mechanisms are coaxial with the tap, and the clamping tube clamps of the other set of feeding mechanisms are coaxial with the die.

[0007] Furthermore, the support frame includes a fixed frame, a flip plate, and a lifting member. The fixed frame is fixedly disposed on one side of the trough, one end of the flip plate is hinged to the fixed frame, and the lifting member is disposed on the other side of the trough and can drive the flip plate to flip. A first mounting seat is provided on the flip plate, and the wiping rod is rotatably disposed on the first mounting seat. The lifting component includes a lifting electric cylinder, a first hinge seat, and a second hinge seat. The first hinge seat is fixedly mounted on the side wall of the tank, and the second hinge seat is fixedly mounted on the flip plate. The cylinder of the lifting electric cylinder is hinged to the first hinge seat, and the piston rod of the lifting electric cylinder is hinged to the second hinge seat.

[0008] Furthermore, the bottom of the flip plate is provided with an inclined support, and the support has an arc-shaped groove for supporting the power protection pipe; when the flip plate is in a horizontal state, the support is in a downward inclined state; when the flip plate is flipped to an upward inclined state, the support is in a horizontal state.

[0009] Furthermore, the drive assembly includes a drive motor, a drive gear, and a driven gear. A second mounting base is provided on the flip plate. The drive gear is rotatably mounted in the second mounting base. The drive motor is located on one side of the second mounting base, and the output shaft of the drive motor is coaxially connected to the drive gear. The driven gear is coaxially connected to the wiping rod and located in the first mounting base. The driven gear meshes with the drive gear.

[0010] Furthermore, strip-shaped protrusions are provided on the outer wall of the wiping block and the inner wall of the wiping sleeve.

[0011] Furthermore, an alignment seat is rotatably provided on the side of the fixed base facing the tank in the horizontal direction, and an alignment plate is slidably provided on the alignment seat in the vertical direction for abutting against the end of the power protection tube.

[0012] Furthermore, the rotating assembly includes a rotating motor, a first sprocket, a second sprocket, and a chain. The first sprocket and the second sprocket are both rotatably disposed at the bottom of the trough. The chain is connected between the first sprocket and the second sprocket. The rotating motor is fixed to the bottom of the trough by a motor mount, and the output shaft of the rotating motor is fixedly connected to the first sprocket.

[0013] Furthermore, the first sprocket is rotatably connected to the groove body via a first rotating shaft, and the top end of the first rotating shaft is fixedly connected to the die via multiple connecting rods; the second sprocket is rotatably connected to the groove body via a second rotating shaft, and the top end of the second rotating shaft is fixedly connected to the tap.

[0014] Furthermore, the bottom wall of the tank includes a horizontal portion in the middle and inclined portions on both sides, wherein the end of the inclined portion closer to the horizontal portion is lower than the end of the inclined portion farther from the horizontal portion.

[0015] The technical solution of the present invention has at least the following advantages and beneficial effects: 1. This invention uses multiple clamping clamps to fix the power protection pipe to ensure its stability. The flipping component moves the power protection pipe to a vertical position, at which point the downward-facing end of the power protection pipe is immersed in liquid and filled with liquid. Then, the pushing component pushes the sliding seat to slide so that the power protection pipe moves vertically. The thread processing mechanism performs thread processing. Since the power protection pipe is filled with liquid during the thread processing, the overall rigidity of the thread processing part can be improved, reducing the possibility of deformation and breakage. In addition, the debris generated during the processing can directly enter the water, reducing the difficulty of cleaning the debris inside the power protection pipe later.

[0016] 2. This invention uses a lifting component to drive the tilting plate to rotate, thus switching the state of the tilting plate. When the tilting plate is in a horizontal state, the support is tilted downwards, which does not obstruct the movement of the power protection tube. When the tilting plate is tilted upwards by the lifting component and the support is in a horizontal state, the support can support the power protection tube. First, the power protection tube is pulled to move the end with the connector tube from one set of feeding mechanisms to the support. Then, the power protection tube is pulled to move it to the next set of feeding mechanisms. This eliminates the need for workers to remove the power protection tube from one set of feeding mechanisms and reinstall it on another, reducing the difficulty of operation for workers.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0020] The following is for reference Figures 1-8 As shown in the figure, and further illustrated with specific embodiments, this embodiment provides a power protection pipe thread processing device, referring to... Figure 1 , Figure 2 As shown, the device includes a tank 1, a thread processing mechanism 2, two sets of feeding mechanisms 3, and a wiping mechanism 4. The tank 1 is filled with liquid and has support legs 11 at its bottom. The thread processing mechanism 2 is located inside the tank 1 and submerged in the liquid. The thread processing mechanism 2 includes a tap 21, a die 22, and a rotating assembly 23. The tap 21 and the die 22 are respectively located on both sides inside the tank 1. The rotating assembly 23 is located at the bottom of the tank 1 and can drive the tap 21 and the die 22 to rotate synchronously. The two sets of feeding mechanisms 3 are respectively located on both sides of the top of the tank 1 and are used to feed the end of the power protection tube into the liquid in the tank 1 and enable the thread processing mechanism 2 to process threads on the power protection tube. The wiping mechanism 4 is set on the top of the tank 1 and located between the two sets of feeding mechanisms 3. The wiping mechanism 4 includes a support frame 41, on which a wiping rod 42 and a drive assembly 43 for driving the wiping rod 42 to rotate are provided. One end of the wiping rod 42 is provided with a wiping block 421 and the other end is provided with a wiping sleeve 422. After the thread processing is completed, the wiping block 421 can wipe the debris inside the connector tube of the power protection tube, and the wiping sleeve 422 can wipe the debris on the outside of the end of the power protection tube.

[0021] During the installation of the power protection pipe, the two sets of feeding mechanisms 3 are horizontal and located outside the tank 1. Two power protection pipes are installed on the two sets of feeding mechanisms 3 respectively, with the connector of one power protection pipe facing the tank 1 and the end of the other power protection pipe away from the connector facing the tank 1. Then, the feeding mechanism 3 first rotates the power protection pipe 90° so that the connector of one power protection pipe aligns with the tap 21 and the end of the other power protection pipe aligns with the die 22. At this time, the end of the power protection pipe facing into the tank 1 is immersed in liquid and filled with liquid. Then, the feeding mechanism 3 drives the power protection pipe downwards so that the tap 21 creates an internal thread on the inner wall of the connector of the power protection pipe, and the die 22 creates an external thread on the outer wall of the end of the power protection pipe. Because the power protection pipe is filled with liquid during the threading process, the overall rigidity of the threaded part is improved, reducing the possibility of deformation and breakage, thereby improving the product qualification rate. Since the threading process is completed in liquid, there is no need to add an additional cooling mechanism, and the debris generated during the process can directly enter the water, reducing the difficulty of cleaning debris inside the power protection tube later.

[0022] Reference Figure 3 As shown, the feeding mechanism 3 includes a fixed base 31, a tilting base 32, a sliding base 33, and multiple clamping clamps 34. The fixed base 31 is fixedly mounted on the tank 1, and the tilting base 32 is rotatably mounted on the fixed base 31. The fixed base 31 is provided with a tilting component 35 for driving the tilting base 32 to tilt. The sliding base 33 is slidably mounted on the tilting base 32, and the tilting base 32 is provided with a pushing component 36 for driving the sliding base 33 to slide. Multiple clamping clamps 34 are mounted on the sliding base 33 and can clamp the power protection tube. The power protection tube is fixed by multiple clamping clamps 34 to ensure the stability of the power protection tube. Then, the tilting component 35 drives the power protection tube to move to a vertical position. At this time, the downward-facing end of the power protection tube is immersed in the liquid and the inside is filled with liquid. Then, the pushing component 36 pushes the sliding base 33 to slide, so that the power protection tube can move vertically to contact the tap 21 or die 22, and the threading operation can begin. In this embodiment, the flipping component 35 is selected as a worm gear mechanism, but in other embodiments, a bevel gear mechanism can also be selected; in this embodiment, the pushing component 36 is selected as a propulsion electric cylinder, but in other embodiments, a hydraulic cylinder or a pneumatic cylinder can also be selected.

[0023] It should be noted that when the sliding seat 33 is in a horizontal state, the clamping clamps 34 are all coaxial with the wiping rod 42, so as to facilitate the installation of the power protection pipe by the staff and the wiping mechanism 4 to wipe the power protection pipe after the threading process is completed; when the sliding seat 33 is in a vertical state, the clamping clamps 34 of one set of feeding mechanisms 3 can be coaxial with the tap 21, and the clamping clamps 34 of the other set of feeding mechanisms 3 can be coaxial with the die 22, so as to facilitate the alignment of the power protection pipe with the tap 21 or the die 22, so as to facilitate subsequent threading.

[0024] Reference Figure 3 , Figure 5 As shown, a horizontally rotatable alignment seat 311 is mounted on the side of the fixed base 31 facing the inside of the groove 1. An alignment plate 312 is slidably mounted on the alignment seat 311 in the vertical direction to abut against the end of the power protection pipe. When installing the power protection pipe, the alignment seat 311 is rotated to a horizontal position, and the alignment plate 312 is slid upward. When the end of the power protection pipe facing downward in the groove 1 abuts against the alignment plate 312, the operator can determine that the installation position of the power protection pipe is accurate. In this state, the power protection pipe is fixed by clamping the pipe clamp 34. When the power protection pipe is flipped to a vertical position, the distance between the bottom end of the power protection pipe and the tap 21 or die 22 is fixed, thereby ensuring that the thread processing mechanism 2 can perform a complete thread processing operation on the power protection pipe during the subsequent downward movement of the power protection pipe by the pushing member 36. It should be noted that after the power protection pipe is clamped by the clamping clamp 34, the alignment plate 312 is slid downward and the alignment seat 311 is flipped downward to avoid the alignment seat 311 and the alignment plate 312 obstructing the movement of the power protection pipe.

[0025] Reference Figure 2 , Figure 5 As shown, the bottom wall of the tank 1 includes a horizontal portion 12 in the middle and inclined portions 13 on both sides. The end of the inclined portion 13 closer to the horizontal portion 12 is lower than the end of the inclined portion 13 farther from the horizontal portion 12. The tap 21 and the die 22 are respectively mounted on the inclined portions 13 on both sides. After the debris generated during thread machining sinks into the liquid, it can slide from the inclined portion 13 to the horizontal portion 12 under its own gravity, thereby avoiding the accumulation of waste near the thread machining position.

[0026] Reference Figure 4As shown, the rotating assembly 23 includes a rotating motor 231, a first sprocket 232, a second sprocket 233, and a chain 234. Both the first sprocket 232 and the second sprocket 233 are rotatably mounted at the bottom of the groove 1. The chain 234 connects the first sprocket 232 and the second sprocket 233. The rotating motor 231 is fixed to the bottom of the groove 1 via a motor mount, and its output shaft is fixedly connected to the first sprocket 232. The first sprocket 232 is rotatably connected to the groove 1 via a first rotating shaft 235, the top end of which is fixedly connected to a die 22 via multiple connecting rods 2351. The second sprocket 233 is rotatably connected to the groove 1 via a second rotating shaft 236, the top end of which is fixedly connected to a tap 21. By rotating the motor 231, the first sprocket 232 is driven to rotate. Under the meshing action of the chain 234, the second sprocket 233 rotates synchronously, thereby driving the tap 21 and the die 22 to rotate simultaneously. When the bottom end of the power protection tube moves towards the bottom wall of the tank 1 to the designated position, the tap 21 can perform internal thread processing on the connector of one of the power protection tubes, and the die 22 can perform external thread processing on the end of the other power protection tube.

[0027] Reference Figure 2 , Figure 6 As shown, the drive assembly 43 includes a drive motor 431, a drive gear 432, and a driven gear 433. A second mounting base 4122 is provided on the flip plate 412. The drive gear 432 is rotatably disposed in the second mounting base 4122. The drive motor 431 is disposed on one side of the second mounting base 4122, and the output shaft of the drive motor 431 is coaxially connected to the drive gear 432. The driven gear 433 is coaxially connected to the wiping rod 42 and located in the first mounting base 4121. The driven gear 433 meshes with the drive gear 432.

[0028] Reference Figure 6 As shown, the support frame 41 includes a fixed frame 411, a flip plate 412, and a lifting member 413. The fixed frame 411 is fixed to one side of the trough 1. One end of the flip plate 412 is hinged to the fixed frame 411. The lifting member 413 is located on the other side of the trough 1 and can drive the flip plate 412 to flip. A first mounting seat 4121 is provided on the flip plate 412. The wiping rod 42 is rotatably connected to the first mounting seat 4121. A support seat 414 is inclinedly provided at the bottom of the flip plate 412. An arc-shaped groove 4141 for supporting the power protection pipe is opened on the support seat 414.

[0029] After the threading process of the power protection pipe is completed, the power protection pipe is driven upward by the pusher 36 to separate from the threading mechanism 2. Then, the power protection pipe is driven outward of the groove 1 by the flipper 35 to a horizontal state. At this time, the threaded part of the power protection pipe needs to be wiped. The flipper 412 is driven to a horizontal state by the lifting member 413. At this time, the support 414 is tilted downward and will not hinder the movement of the power protection pipe. The power protection pipe in the horizontal state is pushed again by the pusher 36, which can make the end of the power protection pipe move closer to the wiping rod 42. The wiping block 421 located at one end of the wiping rod 42 can wipe the debris inside the joint of the power protection pipe. The wiping sleeve 422 located at the other end of the wiping rod 42 can wipe the debris on the outside of the end of the power protection pipe.

[0030] Reference Figure 7 , Figure 8 As shown, after the wiping process is completed, the lifting component 413 drives the flipping plate 412 to flip upward and puts the support 414 in a horizontal state. At this time, the support 414 can support the power protection tube. During the batch processing of power protection tubes, each power protection tube is first installed on one set of feeding mechanisms 3 for processing the internal thread of the connector tube, and then installed on another set of feeding mechanisms 3 for processing the external thread of the end. During the process of the power protection tube moving from one set of feeding mechanisms 3 to the next set of feeding mechanisms 3, the support 414 can provide support between the two sets of feeding mechanisms 3. First, the power protection tube is pulled to move the end of the power protection tube with the connector tube to the support 414, and then the power protection tube is pulled to move the power protection tube to the next set of feeding mechanisms 3. There is no need for the operator to remove the power protection tube from one set of feeding mechanisms 3 and reinstall it on another set of feeding mechanisms 3, which reduces the difficulty of operation for the operator.

[0031] Furthermore, the lifting component 413 includes a lifting electric cylinder 4131, a first hinge seat 4132, and a second hinge seat 4133. The first hinge seat 4132 is fixedly mounted on the side wall of the tank 1, and the second hinge seat 4133 is fixedly mounted on the flip plate 412. The cylinder of the lifting electric cylinder 4131 is hinged to the first hinge seat 4132, and the piston rod of the lifting electric cylinder 4131 is hinged to the second hinge seat 4133. Activating the lifting cylinder 4131 and moving its piston rod outwards from the cylinder barrel allows the second hinge seat 4133 to drive the tilting plate 412 to tilt upwards, thus enabling the support seat 414 to support the power protection tube. Activating the lifting cylinder 4131 and moving its piston rod inwards from the cylinder barrel allows the second hinge seat 4133 to drive the tilting plate 412 to tilt downwards to a horizontal position, thus enabling the wiping block 421 and wiping sleeve 422 on the wiping rod 42 to wipe the threaded parts of the power protection tube.

[0032] It should be noted that both the wiping block 421 and the wiping sleeve 422 are made of flexible materials such as foam or sponge, which can deform to adapt to the threaded parts on the power protection pipe. Furthermore, strip-shaped protrusions 423 are provided on the outer wall of the wiping block 421 and the inner wall of the wiping sleeve 422 to improve the wiping effect.

[0033] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
