Description

Technical Field

[0001] This application relates to the technical field of special production equipment for conductors, and in particular, to a production equipment for cross-linked polyethylene insulated power cables. Background Art

[0002] A cross-linked polyethylene insulated power cable includes an external insulation protective sheath and an internal core. The protective sheath is made of cross-linked polyethylene and is mainly used to protect the core. The core is formed by stranding a plurality of conductors. During the production process of power cables, multiple special equipment is required, such as a stranding machine. The stranding machine is mainly used to strand multiple conductors together to form a core, which is a core step in the production process of power cables.

[0003] The stranding machine mainly includes a frame and a stranding frame. The stranding frame is rotatably connected to the frame. A plurality of wire reels are arranged along the circumferential direction of the stranding frame. One end of the conductor on the wire reel moves under the action of a traction device, and at the same time, the stranding frame rotates to achieve the stranding of the power cable. For example, a stranding machine disclosed in a patent document with the publication number CN109671540B mainly includes a base, a main stranding cage, and a motor. The wire reels are arranged on the main stranding cage, and the motor is used to drive the main stranding cage to rotate. The rotation of the main stranding cage drives the wire reels to move in a circular motion, thereby achieving stranding.

[0004] During the production process of power cables, when the conductors on the wire reel are consumed, the wire reel needs to be replaced. For small wire reels, the staff can easily complete the replacement of the wire reel. However, for larger wire reels, due to the weight of the wire reel, the labor burden on the staff is large and the replacement efficiency is low. Of course, when replacing the wire reel, a hoist can be used to lift the wire reel, but it still requires the staff to assist beside. Under long-term work, it will still cause the problems of large labor burden on the staff and long working hours of the wire reel, thereby affecting the production efficiency of power cables. Summary of the Invention

[0005] In order to improve the production efficiency of power cables, this application provides a production equipment for cross-linked polyethylene insulated power cables.

[0006] The production equipment for cross-linked polyethylene insulated power cables provided by this application adopts the following technical solutions: A cross-linked polyethylene insulated power cable production device includes a frame and a cage rotatably connected to the frame, and further includes a feeding device. The feeding device includes a feeding pipeline and a material grabbing mechanism. An outlet is provided on the feeding pipeline, and a wire reel can be moved out from the outlet. The material grabbing mechanism includes a clamping component and a moving component. The clamping component is installed on the moving component for clamping the wire reel. The moving component includes a rotating frame installed on the frame. The rotating frame includes a first rotating side and a second rotating side. The first rotating side is close to the outlet, and the second rotating side is close to the cage. The first rotating side and the second rotating side can be rotatably connected to the frame. The first rotating side is connected to the frame, and the rotating frame can drive the clamping component close to the outlet. The second rotating side rotates with the frame, and the rotating frame can drive the clamping component close to the cage.

[0007] By adopting the above technical solution, the wire reel is conveyed to the outlet through the feeding pipeline. Control the first rotating side of the rotating plate to be rotatably connected to the frame. Drive the clamping component close to the outlet by rotating the rotating frame, and clamp the wire reel at the outlet. Subsequently, the rotating frame resets, the second rotating side is connected to the frame, and drive the wire reel close to the cage by rotating the rotating frame in the reverse direction to realize the feeding of the wire reel. Through the alternating rotation connection on both sides of the rotating plate, the rapid feeding and taking of the wire reel are realized, the efficiency of replacing the wire reel is improved, the labor burden of the staff is reduced, and the overall production efficiency is improved.

[0008] Optionally, a sliding component is provided between the material grabbing mechanism and the frame. The sliding component includes a sliding seat and a rotating ring. The sliding seat is slidably connected to the frame along a direction parallel to the rotation axis of the cage.

Moving the limiting plate can make the limiting plate abut against the rotating shaft to prevent the rotation from occurring displacement in the direction perpendicular to its own axis.

[0011] By adopting the above technical solution, the displacement of the rotating shaft in the direction perpendicular to its own axis is limited by rotating the limiting plate, reducing the degree of freedom of the rotating shaft, so that it is rotatably connected to the rotating ring. When the limiting plate is rotated to make it away from the rotating shaft, the rotating shaft is disconnected from the rotating ring, thus realizing the connection and disconnection between the rotating frame and the rotating ring.

[0014] Optionally, the side wall of the open rotation groove is arc-shaped, the limiting plate is an arc-shaped plate, and the limiting plate rotates on the fixed block.

[0015] By adopting the above technical solution, the open rotation groove and the limit plate are both configured to be arc-shaped, so that after being rotated and embedded in the open rotation groove, they can fit with the side wall of the shaft, thereby improving the stability of the shaft during rotation.

[0016] Optionally, two limit plates are provided, and the two limit plates are respectively provided on both sides of the open rotation groove.

[0017] By adopting the above technical solution, two limit plates are provided, which can improve the stability of the limit of the rotating shaft on the one hand, and on the other hand, can reduce the curvature of the limit plate itself, so that the limit plate does not need to be made with a larger curvature.

[0018] Optionally, the two limit plates are spaced apart in a direction parallel to their own rotation axes, a linkage bevel gear is arranged between the two limit plates, the linkage bevel gear is rotatably connected to the fixed block, and the limit plates are provided with tooth grooves meshing with the linkage bevel gear.

[0019] By adopting the above technical solution, the linkage between the two limit plates is achieved through the cooperation between the linkage bevel gear and the tooth groove, which facilitates the synchronous adjustment of the position between the two limit plates.

[0020] Optionally, a swing arm is provided on one of the limit plates, and the swing arm extends in a direction perpendicular to the rotation axis of the limit plate.

[0021] By adopting the above technical solution, the force arm when driving the limit plate to rotate is increased by the swing arm, which facilitates the rotation of the limit plate.

[0022] Optionally, a linkage rod is disposed between the swing arms on the two limiting plates, and both ends of the linkage rod are rotatably connected to the swing arms.

[0023] By adopting the above technical solution, both ends of the linkage rod are rotatably connected to the two swing arms, realizing the connection between the two swing arms and facilitating the synchronous adjustment of the positions of the two swing arms.

[0024] Optionally, a telescopic driving member is disposed on the rotating ring.

Detailed implementation mode

[0028] The following will Figures 1-7 further describe the present application in detail.

[0029] An embodiment of the present application discloses a cross-linked polyethylene insulated power cable production device.

[0030] Referring to Figure 1 and Figure 2 , a cross-linked polyethylene insulated power cable production device includes a frame 1 and an auger 2 rotatably connected to the frame 1, and the rotation axis of the auger 2 is parallel to the ground. A feeding device 3 is arranged on the frame 1, and the feeding device 3 includes a feeding pipeline 32 and a material grasping mechanism 4. The feeding pipeline 32 is arranged above the auger 2, and one end of the feeding pipeline 32 extends downward and is provided with a discharge port 321. The material grasping mechanism 4 includes a movable assembly 41 and a clamping assembly 42. The movable assembly 41 is installed on a sliding assembly 8, and the clamping assembly 42 is installed on the movable assembly 41. The movable assembly 41 is used to drive the clamping assembly 42 to approach the discharge port 321 or the auger 2, and the clamping assembly 42 is used to grasp the wire reel.

[0031] Referring to Figure 1 and Figure 2, an elastic interception component 5 is arranged inside the material conveying pipeline 32 at a position corresponding to the discharge port 321. The elastic interception component 5 includes a baffle 51 and an elastic member 52. One side of the baffle 51 is rotatably connected to the inner side wall of the discharge port 321, and the other side extends downward and away from the inner side wall of the material conveying pipeline 32. The elastic member 52 is installed in the material conveying pipeline 32 and is used to block the baffle 51 from rotating towards the side wall close to the discharge port 321. After the wire reel slides to the discharge port 321, the baffle 51 can block the wire reel from falling out of the discharge port 321. And when the clamping component 42 grabs the wire reel, it can drive the wire reel to move out of the material conveying pipeline 32 against the elastic force of the elastic member 52. In this embodiment, the elastic member 52 is a rubber block, and the rubber block is adhesively connected to the inner side wall of the material conveying pipeline 32. One side of the baffle 51 close to the inner side wall of the material conveying pipeline 32 abuts against the rubber block, so as to block the baffle 51 from rotating towards the side wall close to the material conveying pipeline 32 to a certain extent.

[0032] Referring to Figure 1 and Figure 2 , the feeding device 3 further includes a sliding component 8. The sliding component 8 is installed on the frame 1, and the material grabbing mechanism 4 is installed on the sliding component 8. The sliding component 8 is used to drive the material grabbing mechanism 4 to slide along the length direction of the auger 2. So as to facilitate the installation of wire reels at multiple positions in the axial direction of the auger 2. The sliding component 8 includes a sliding seat 81 and a rotating ring 82. The sliding seat 81 is slidably connected to the frame 1 along the axis direction of the auger 2. The rotating ring 82 is integrally in a plate-like structure and is circular. The rotating ring 82 is sleeved outside the auger 2 and is rotatably connected to the sliding seat 81. The rotation axis of the rotating ring 82 is coaxial with the rotation axis of the auger 2. The movable component 41 is installed on the rotating ring 82, and the rotating ring 82 can drive the movable component 41 to move around the axis of the auger 2, so as to install wire reels at different positions in the axial direction of the auger 2.

[0033] Referring to Figure 1 and Figure 2 , a plurality of material grabbing mechanisms 4 are uniformly arranged at intervals along the circumferential direction of the rotating ring 82. The plurality of material grabbing mechanisms 4 correspond to the positions on the auger 2 in the axial direction for installing wire reels, so as to facilitate the simultaneous installation of wire reels at multiple positions in the axial direction of the auger 2 and improve the feeding efficiency.

[0034] Referring to Figure 1 and Figure 2 , the movable component 41 includes a rotating frame 411 and a connection control component 412. The rotating frame 411 is integrally in a plate-like structure and is arranged parallel to the rotating ring 82. Define the side of the rotating frame 411 close to the discharge port 321 as the first rotating side 4111, and the side of the rotating frame 411 close to the auger 2 as the second rotating side 4112. The connection control component 412 is arranged in two groups corresponding to the first rotating side 4111 and the second rotating side 4112. The connection control component 412 can control the first rotating side 4111 and the second rotating side 4112 to be rotatably connected to or disconnected from the rotating ring 82.

[0035] Referring to Figure 1 and Figure 2 During the loading and unloading process, when it is necessary to drive the clamping assembly 42 close to the discharge port 321, the connection control assembly 412 controls the first rotating side 4111 to be rotatably connected to the rotating ring 82, and the second rotating side 4112 disconnects the connection with the rotating ring 82. At this time, rotating the rotating frame 411 can drive the clamping assembly 42 close to the discharge port 321. After the clamping assembly 42 grabs the wire reel, the rotating frame 411 rotates, making the second rotating side 4112 close to the rotating ring 82 and driving the wire reel close to the auger 2 at the same time. When the rotating frame 411 is parallel to the rotating ring 82, control the second rotating side 4112 to be connected to the rotating ring 82 and disconnect the connection between the first rotating side 4111 and the rotating ring 82. At this time, the rotating member rotates, and the first rotating side 4111 can move in the direction close to the auger 2, thereby driving the wire reel close to the auger 2.

[0036] Referring to Figure 3 and Figure 4 The connection control assembly 412 includes a fixed block 4121 and a limiting plate 4122. The fixed block 4121 is arranged between the rotating frame 411 and the rotating ring 82, and the fixed block 4121 is welded to the rotating ring 82. Rotating shafts 4124 are arranged at positions of the first rotating side 4111 and the second rotating side 4112 corresponding to the connection control assembly 412, and the axis of the rotating shaft 4124 is perpendicular to the axis of the auger 2. An open rotating groove 4123 is formed on one side of the fixed block 4121 corresponding to the rotating shaft 4124. The side wall of the open rotating groove 4123 is arc-shaped, and its radian is not greater than π. The rotating shaft 4124 can be embedded in the open rotating groove 4123 and can enter and exit the open rotating groove 4123 arbitrarily. The limiting plate 4122 is an arc-shaped plate structure. The limiting plate 4122 is rotatably connected to the fixed block 4121, and the inner diameter of the inner side wall of the limiting plate 4122 is equal to the diameter of the rotating shaft 4124. Rotating the limiting plate 4122 can move one end of the limiting plate 4122 to the side of the fixed block 4121 away from the rotating ring 82. Combining Figure 2 The sum of the radian of the side wall of the limiting plate 4122 and the open rotating groove 4123 is greater than π, so as to prevent the rotating shaft 4124 from disengaging from the open rotating groove 4123 and realize the rotational connection between the rotating frame 411 and the rotating ring 82.

[0037] Referring to Figure 3 and Figure 4 Two limiting plates 4122 are arranged at both ends of the arc-shaped track corresponding to the side wall of the open rotating groove 4123. When the rotating shaft 4124 is located in the open rotating groove 4123, rotate the limiting plate 4122, and the limiting plate 4122 limits the rotating shaft 4124 from both sides, improving the connection stability between the rotating shaft 4124 and the fixed block 4121.

[0038] Reference Figure 3 and Figure 4 As shown, the two limiting plates 4122 are arranged at intervals in the direction parallel to their own rotation axes, and a linkage assembly 6 is arranged between the two limiting plates 4122.

The two linkage arc plates 62 are respectively welded coaxially on the two limiting plates 4122, the linkage bevel gear 61 is arranged between the two linkage arc plates 62, and is rotatably connected to the fixed block 4121. Tooth grooves meshing with the linkage bevel gear 61 are arranged on the side surfaces of the linkage arc plates 62 close to the linkage bevel gear 61, so as to realize the synchronous rotation between the two limiting plates 4122.

In the actual loading and unloading process, the limiting plate 4122 of the connection control assembly 412 corresponding to the first rotating side 4111 or the second rotating side 4112 is in the limiting state, that is, only one side of the rotating frame 411 is rotatably connected to the rotating ring 82.

[0040] Reference Figure 4 and Figure 5 As shown, a driving assembly 7 is arranged between the two groups of connection control assemblies 412.

One end of the swing arm 71 is welded to the limiting plate 4122, and the other end extends in the direction perpendicular to the axis of the limiting plate 4122. By the swing arm 71, the force arm during the rotation of the limiting plate 4122 is increased, which is convenient for the staff to rotate the limiting plate 4122. The driving assembly 7 further includes a linkage rod 72. Both ends of the linkage rod 72 are respectively rotatably connected to the two swing arms 71. Moving the linkage rod 72 can drive the two swing arms 71 to rotate simultaneously, so as to facilitate the synchronous rotation of multiple limiting plates 4122.

The sliding block 73 is slidably connected to the rotating ring 82 along the direction parallel to the linkage rod. The linkage rod 72 is connected to the sliding block 73 and can move relative to the sliding block 73 in the direction perpendicular to the linkage rod 72 to adapt to the displacement of the linkage rod 72 in the direction perpendicular to its own length during the process of the linkage rod 72 driving the swing arm 71 to rotate. In this embodiment, the sliding block 73 is driven by an electric push rod, and in other embodiments, it can also be driven by a cylinder or an oil cylinder.

[0042] Reference Figure 6 and Figure 7The clamping assembly 42 includes two clamping plates 421 rotatably connected to the rotating frame 411, and the two clamping plates 421 are arranged in parallel and spaced apart in a direction parallel to the axis of the rotating shaft 4124. The rotating clamping plates 421 can make the two clamping plates 421 away from the rotating frame 411 side approach or move away from each other, thereby clamping the wire drum.

[0043] Reference Figure 6 and Figure 7 The clamping assembly 42 also includes a force block 422 and a force rod 423. Two force rods 423 are provided corresponding to the clamping plate 421. One end of the two force rods 423 is welded to the clamping plate 421, and the other end extends in a direction close to each other. The force block 422 is arranged between the two force rods 423.

The force block 422 is slidably connected to the rotating frame 411 in a direction perpendicular to the rotating frame 411. The sliding force block 422 can drive the force end 424 to move, thereby driving the clamping plate 421 to rotate, so as to adjust the position of the clamping plate 421.

[0044] Reference Figure 6 and Figure 7 A threaded rod 426 is rotatably provided on the rotating frame 411, and the threaded rod 426 is threadedly connected to the force block 422. Rotating the threaded rod 426 can drive the force block 422 to move, thereby driving the force block 422, and at the same time, the self-locking property of the thread can be used to improve the stability of the clamping plate 421 clamping the wire drum.

The telescopic driving member 31 applies a force to the rotating frame 411. Under the action of the force, the rotating frame 411 rotates, driving the clamping assembly 42 to approach the discharge port 321, and the clamping assembly 42 clamps the wire reel at the discharge port 321. Subsequently, the rotating frame 411 rotates. When the rotating frame 411 is parallel to the rotating seat. The rotating ring 82 rotates to make another set of material-grabbing mechanisms 4 correspond to the discharge port 321, and multiple clamping assemblies 42 are sequentially cycled to hold wire reels. Subsequently, the sliding seat 81 slides to a designated position, the second rotating side 4112 of multiple sets of material-grabbing mechanisms 4 is rotatably connected to the rotating ring 82, and the connection between the first rotating side 4111 and the rotating ring 82 is disconnected. At this time, the telescopic driving member 31 can drive the rotating frame 411 to rotate around the rotation axis of the second rotating side 4112, thereby driving the clamping assembly 42 to approach the cage 2 to achieve synchronous feeding of multiple wire reels.
