Description
Technical Field
[0001] This utility model relates to the field of cable cross-linking technology, specifically to a steam cross-linking oven for power cables. Background Technology
[0002] Steam cross-linking is a crucial step in the production of power cables, enhancing their insulation performance and mechanical strength. Traditional steam cross-linking furnaces for power cables present several operational inconveniences, such as requiring manual feeding of the cables into the furnace, which is cumbersome and inefficient.
[0003] According to a public notice (publication number: CN207474147U) regarding a steam crosslinking furnace for power cables: a power cable track transport frame is installed in the center of the entrance of the silane crosslinking steam crosslinking furnace; the structure of the silane crosslinking steam crosslinking furnace is as follows: an insulation layer is installed between the outer surface of the container and the protective layer; a water tank is installed on the upper surface of the protective layer; an inner track is installed on the bottom surface of the container; the steam outlet of the steam pipe of the fully automatic steam generator is located at the bottom inside the container; the structure of the power cable track transport frame is as follows: at least three columns are vertically installed between the upper and lower frames; an outer track is installed parallel above the crossbeams on both sides of the upper frame; the columns located at the rear end of the upper and lower frames are connected to the fixed frames on both sides of the vertical part of the inclined support; one end of the outer track of the power cable track transport frame with a connecting plate is connected to the connecting frame of the inner track of the container; this solves the problem of reducing material consumption and improving cooking efficiency in the process of plastic steam crosslinking in existing steam crosslinking furnaces, and is energy-saving and environmentally friendly.
[0004] In the above application, although the setting of the power cable track transport frame has realized the automated feeding of power cables into the furnace, there are still problems such as complicated operation and insufficient automation. It is impossible to realize the automated feeding of power cables into the furnace, and the labor cost is high. Therefore, we propose a steam cross-linking furnace for power cables. Utility Model Content
[0005] To overcome the above-mentioned defects, this utility model provides a steam crosslinking furnace for power cables, which solves the technical problems of existing steam furnaces being inconvenient to operate and unable to automatically feed the cables.
[0006] According to one aspect, at least one embodiment of the present invention provides a steam crosslinking oven for power cables, comprising: an oven, a foot pad fixedly connected to the bottom of the oven, a hinge block fixedly connected to the side of the oven, a door panel hinged to the inner side of the hinge block, an electric cable feeding device provided inside the oven, and a control panel provided on the side of the oven.
[0007] The electric cable feeding device includes a fixing block, which is fixedly connected to the side of the steam oven. A motor is fixedly connected to the top of the fixing block, and a threaded rod is fixedly connected to the output shaft of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod, and a movable feeding plate is fixedly connected to the circumferential surface of the threaded sleeve. An installation block is fixedly connected to the top of the movable feeding plate, and a cable feeding plate is fixedly connected to the top of the installation block. A hollow block is fixedly connected to the inner side of the steam oven, a limit sliding plate is fixedly connected to the side of the movable feeding plate, and a sliding plate is fixedly connected to the bottom of the movable feeding plate. A sliding groove is provided at the bottom of the inner side of the steam oven.
[0008] For example, in a steam crosslinking oven for power cables provided in at least one embodiment of the present invention, a buffer spring is fixedly connected to the inner side of the oven, and a buffer pad is fixedly connected to the end of the buffer spring away from the oven. Its function is to provide buffering after the cable moves into the oven, reduce impact force, and protect the cable and equipment.
[0009] The side of the buffer pad is located on the displacement trajectory of the side of the moving feed plate. There are two buffer pads and two buffer springs, which are symmetrically distributed along the vertical central axis of the moving feed plate. Their function is to effectively reduce the collision between the moving feed plate and the inner wall of the steam oven and improve the service life of the equipment.
[0010] The circumferential surface of the motor output shaft penetrates and is rotatably connected to the side of the steam oven. There are two motors and two fixing blocks, which are symmetrically distributed along the vertical central axis of the steam oven. Their function is to ensure the smooth operation of the electric cable feeding device and improve the efficiency of the work.
[0011] The side of the limiting slide plate is slidably connected to the inner side of the hollow block, and the side of the sliding plate is slidably connected to the inner side of the slide groove. Its function is to ensure that the moving feeding plate is accurately limited during left and right movement, prevent deviation, and ensure the stability and safety of the cable entering the steam oven after being loaded.
[0012] According to another aspect, at least one embodiment of the present invention also provides a steam crosslinking oven for power cables, comprising: a pre-steam wiping device, wherein the pre-steam wiping device is provided on the side of the steam oven, the pre-steam wiping device includes a connecting plate, a rack is fixedly connected to the side of the connecting plate, a rotating plate is fixedly connected to the side of the steam oven, a wire wheel is rotatably connected through the side of the rotating plate, a gear is fixedly connected to one end of the wire wheel, a pull wire is provided on the circumference of the wire wheel, a pull post one is fixedly connected to the end of the pull wire away from the wire wheel, a pull post two is hinged to the end of the pull post one away from the pull wire, a wiping block is fixedly connected to the end of the pull post two away from the pull post one, and a wiping block limiting plate is fixedly connected to the top of the steam oven, the function of which is to wipe the cable before steam crosslinking, thereby cleaning the surface stains of the cable.
[0013] For example, in a steam crosslinking oven for power cables provided in at least one embodiment of the present invention, a guide auxiliary wheel is fixedly connected to the top of the oven, and a counterweight is provided on the top of the wiping block. The counterweight is used to prevent the pull wire from contacting the corner of the oven and to increase the stability of the wiping block.
[0014] The gear and rack mesh with each other, and the side of the rack penetrates and slides through the side of the steam oven. Its function is to drive the rack to move through the feeding plate, thereby meshing with the gear and realizing the winding of the spool, thus achieving the raising and lowering of the wiping block.
[0015] The wiping block is located above the movable feeding plate. The circumferential surface of the first pull column penetrates and slides through the side of the wiping block limiting plate. Its function is to ensure that the wiping block does not deviate from the track during movement, and at the same time, it is balanced by the counterweight. It also ensures that when the first pull column is pulled back by the pull line, the second pull column will also retract, reducing friction.
[0016] The side of the wiping block limiting plate is set as an inclined surface. The side of the wiping block limiting plate is located on the displacement trajectory of the two circumferential surfaces of the pull column. There are two counterweights, which are symmetrically distributed along the vertical central axis of the wiping block. Their function is to ensure that the two sides are symmetrically distributed, so as to ensure that the force is balanced during the wiping process, improve the wiping efficiency, and reduce the wear and tear of components caused by friction.
[0017] The beneficial effects of the embodiments of this utility model are as follows: 1. This utility model achieves automatic cable feeding through the direct cooperation of components such as the fixing block, motor, and threaded rod in the electric cable feeding device. This eliminates the need for manual handling, reducing labor intensity and improving work efficiency.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0028] like Figures 1-5 As shown, it illustrates a steam crosslinking oven for power cables according to an embodiment of the present invention, comprising: an oven 1, a foot pad 2 fixedly connected to the bottom of the oven 1, a hinge block 3 fixedly connected to the side of the oven, a door panel 4 hinged to the inner side of the hinge block 3, an electric cable feeding device 5 installed inside the oven 1, and a control panel 11 installed on the side of the oven 1.
[0029] The electric cable feeding device 5 includes a fixing block 501, which is fixedly connected to the side of the steam oven 1. A motor 502 is fixedly connected to the top of the fixing block 501. A threaded rod 503 is fixedly connected to the output shaft of the motor 502. A threaded sleeve 504 is threadedly connected to the circumferential surface of the threaded rod 503. A movable feeding plate 505 is fixedly connected to the circumferential surface of the threaded sleeve 504. An installation block 506 is fixedly connected to the top of the movable feeding plate 505. A cable feeding plate 507 is fixedly connected to the top of the installation block 506. A hollow block 508 is fixedly connected to the inner side of the steam oven 1. A limit slide plate 509 is fixedly connected to the side of the movable feeding plate 505. A sliding plate 510 is fixedly connected to the bottom of the movable feeding plate 505. A groove 511 is opened at the bottom of the inner side of the steam oven 1.
[0030] In some examples, a buffer spring 6 is fixedly connected to the inner side of the steam oven 1, and a buffer pad 7 is fixedly connected to the end of the buffer spring 6 away from the steam oven 1. Its function is to provide buffering after the cable moves into the steam oven 1, reduce the impact force, and protect the cable and equipment.
[0031] The side of the buffer pad 7 is located on the displacement trajectory of the side of the moving feed plate 505. There are two buffer pads 7 and two buffer springs 6, which are symmetrically distributed along the vertical central axis of the moving feed plate 505. Their function is to effectively reduce the collision between the moving feed plate 505 and the inner wall of the steam oven 1 and improve the service life of the equipment.
[0032] The circumferential surface of the output shaft of motor 502 penetrates and is rotatably connected to the side of steam oven 1. There are two motors 502 and two fixing blocks 501, which are symmetrically distributed along the vertical central axis of steam oven 1. Their function is to ensure the smooth operation of electric cable raising device 5 and increase work efficiency.
[0033] The side of the limiting slide plate 509 is slidably connected to the inner side of the hollow block 508, and the side of the sliding plate 510 is slidably connected to the inner side of the slide groove 511. Its function is to ensure that the moving feeding plate 505 is accurately limited during left and right movement, prevent deviation, and ensure the stability and safety of the process of the cable entering the steam oven 1 after being loaded.
[0034] For example, such as Figures 1-5As shown, when the power cable needs to be steam crosslinked in the steam crosslinking oven, the cable to be crosslinked is first placed on the feed plate 507. Then, the operator starts the motor 502. The output shaft of the motor 502 drives the threaded rod 503 to rotate. Since the threaded rod 503 is threadedly connected to the threaded sleeve 504, the rotation of the threaded rod 503 will drive the threaded sleeve 504 to move along the axial direction of the threaded rod 503. The movement of the threaded sleeve 504 further drives the moving feed plate 505 to move. As the moving feed plate 505 moves, the cable is sent into the steam oven 1 for steam crosslinking treatment. During the movement of the moving feed plate 505, the limiting slide plate 509 slides in the hollow block 508, and the sliding plate 510 slides in the groove 511. This design ensures the stability and accuracy of the moving feed plate 505 during left and right movement and prevents deviation.
[0035] When the cable moves to the designated position inside the steam oven 1, the motor 502 stops working. At this time, the cable comes into contact with the buffer pad 7. The buffer pad 7, through the elastic action of the buffer spring 6, buffers the moving feed plate 505, reducing the collision force between the cable and the inner wall of the steam oven 1, protecting the cable and equipment, and improving the service life of the equipment.
[0036] like Figures 1-5 As shown, this invention illustrates a steam crosslinking oven for power cables according to another embodiment of the present invention, comprising: a pre-steam wiping device 8, which includes a connecting plate 801, a rack 802 fixedly connected to the side of the connecting plate 801, a rotating plate 803 fixedly connected to the side of the oven 1, a threaded wheel 804 rotatably connected through the side of the rotating plate 803, a gear 805 fixedly connected to one end of the threaded wheel 804, a pull line 806 provided on the circumferential surface of the threaded wheel 804, a pull post 807 fixedly connected to the end of the pull line 806 away from the threaded wheel 804, a pull post 808 hinged to the end of the pull post 807 away from the pull line 806, a wiping block 809 fixedly connected to the end of the pull post 808 away from the pull post 807, and a wiping block limiting plate 810 fixedly connected to the top of the oven 1. The function of the wiping device 810 is to wipe the cable before steam crosslinking, thereby cleaning the surface dirt of the cable.
[0037] In some examples, a guide auxiliary roller 9 is fixedly connected to the top of the steam oven 1, and a counterweight 10 is provided on the top of the wiping block 809. Its function is to prevent the pull wire 806 from contacting the corner of the steam oven 1. The counterweight 10 is to increase the stability of the wiping block 809.
[0038] Gear 805 meshes with rack 802. The side of rack 802 penetrates and slides through the side of steam oven 1. Its function is to move rack 802 by moving feed plate 505, thereby meshing with gear 805 to realize the winding of reel 804, thus achieving the raising and lowering of wiping block 809.
[0039] The wiping block 809 is located above the movable feed plate 505. The circumferential surface of the pull column 807 penetrates and slides through the side of the wiping block limiting plate 810. Its function is to ensure that the wiping block 809 does not deviate from the track during movement, and at the same time, it is balanced by the counterweight 10. It also ensures that when the pull column 807 is pulled back by the pull line 806, the pull column 808 will also retract, thus reducing friction.
[0040] The side of the wiping block limiting plate 810 is set as an inclined surface. The side of the wiping block limiting plate 810 is located on the displacement trajectory of the circumferential surface of the pull column 808. There are two counterweights 10, which are symmetrically distributed along the vertical central axis of the wiping block 809. Their function is to ensure that the force is balanced during wiping, improve wiping efficiency, and reduce component wear caused by friction.
[0041] For example, such as Figures 1-5 As shown, the working principle is as follows: when the cable is fed into the steam oven 1 via the moving feed plate 505 for steam cross-linking treatment, the surface of the cable has been wiped clean as the moving feed plate 505 continues to move. Once the cable has entered the steam oven 1, the rack 802 will also be driven to slide. The sliding of the rack 802 further meshes with the gear 805, thereby driving the reel 804 to rotate. The rotation of the reel 804 will rewind the pull cable 806, and the release or rewinding of the pull cable 806 will drive the pull column 1 807 to move. Since the pull column 1 807 is hinged to the pull column 2 808, the movement of the pull column 1 807 will further drive the movement of the pull column 2 808. The setting of the wiping block limiting plate 810 ensures that the wiping block 809 does not deviate from the track during movement. At the same time, the inclined design of the wiping block limiting plate 810 allows the pull column 2 808 to slide smoothly along its side, achieving a fast and efficient retraction effect.
[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
