Description

Technical Field

[0001] This utility model relates to the technical field of power cable production and testing equipment, specifically a performance testing platform for power cable production. Background Technology

[0002] Cable performance testing includes DC resistance testing, insulation resistance testing, partial discharge testing, thermal aging testing, insulation strength testing, and thermal stability testing. Cable performance testing is typically performed using testing equipment. Both thermal aging and thermal stability tests require heating devices. However, existing performance testing equipment used in power cable production often results in uneven heating of the cable, which affects the accuracy of the cable's heat resistance test results.

[0003] In the prior art, the authorized patent CN211263255U discloses a performance testing device for power cable production, including a base, side plates, a top plate, a heating component, a fixing mechanism, and a driving mechanism. Side plates are fixedly connected to the left and right sides of the top of the base, and the tops of the two side plates are fixedly connected to the top plate. A heating component is fixedly installed at the midpoint of the bottom of the top plate. Fixing mechanisms are provided on opposite sides of the two side plates, corresponding to the positions of the heating components. A driving mechanism is provided at the midpoint of the top of the base. The heating component includes a mounting block, the top of which is fixedly connected to the bottom of the top plate, and a concave block is fixedly connected to the bottom of the mounting block. This invention, through the cooperation of the base, side plates, top plate, heating component, fixing mechanism, and driving mechanism, ensures uniform heating of the cable during the heating process, thereby guaranteeing the accuracy of the cable's heat resistance performance test results. It is highly practical and worthy of promotion.

[0004] However, the above technical solution still has the following shortcomings in use: the device can only perform heat resistance performance testing on one cable at a time, and cannot test multiple cables simultaneously, which greatly reduces the efficiency of cable performance testing. To address this, we propose a performance testing platform for power cable production to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a performance testing platform for power cable production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a performance testing platform for power cable production, comprising:

[0007] A testing platform is provided with a cover plate at its top. The rear end of the cover plate is hinged to the testing platform. Multiple equidistant semicircular grooves are provided on the top wall of the testing platform and the bottom wall of the cover plate. An arc-shaped heating plate is fixedly installed in each semicircular groove. A pair of L-shaped mounting rods are fixedly welded to each side wall of the testing platform. A fixing plate is fixedly welded to the top of each pair of L-shaped mounting rods. Multiple equidistant first rotating columns are rotatably mounted on the inner wall of the fixing plate through bearings. The multiple first rotating columns are concentrically arranged with the multiple semicircular grooves. A clamping seat is fixedly welded to each of the first rotating columns. A stud is threadedly connected to the top wall of the clamping seat through a threaded hole. A clamping block is installed at the bottom end of the stud.

[0008] Preferably, a first gear is fixedly installed on the first rotating column, and a plurality of second rotating columns are rotatably installed on the inner wall of the fixed plate through bearings. The second rotating columns are located below the middle of two adjacent first rotating columns, and a second gear is fixedly installed on the second rotating column. The second gear is meshed with two first gears located on its upper side.

[0009] Preferably, a dual-axis motor is fixedly installed on the rear side wall of the testing platform, and a rotating rod is fixedly welded to each of the two output shafts of the rotating shaft motor, with a third gear fixedly installed at the outer end of each of the two rotating rods.

[0010] Preferably, the outer ends of the two first rotating columns located on the rear side are fixedly welded with connecting rods, and the outer ends of the connecting rods are fixedly installed with fourth gears, and the two fourth gears are respectively meshed with two third gears.

[0011] Preferably, a controller is fixedly installed on the front side wall of the testing platform, and the controller is electrically connected to multiple arc-shaped heating plates and a dual-axis motor via wires.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model's dual-axis motor can drive two rotating rods to rotate after startup. The two rotating rods are connected by the meshing of a third gear and a fourth gear, which can synchronously drive two connecting rods to rotate, thereby driving the two first rotating columns on the rear side to rotate. Through the arrangement of multiple second rotating columns and the cooperation of the second gear and the first gear, multiple first rotating columns can rotate synchronously, thereby driving multiple clamped cables to rotate and achieving uniform heating of multiple cables. This facilitates the simultaneous testing of the heat resistance performance of multiple cables, greatly improving the work efficiency during cable testing. Attached Figure Description

[0020] Please see Figure 1-4 This utility model provides a technical solution: a performance testing platform for power cable production, comprising:

[0021] A testing platform 1 is provided with a cover plate 2 at its top. The rear end of the cover plate 2 is hinged to the testing platform 1. Multiple equidistant semicircular grooves 3 are provided on the top wall of the testing platform 1 and the bottom wall of the cover plate 2. An arc-shaped heating plate 4 is fixedly installed in the semicircular grooves 3. A pair of L-shaped mounting rods 5 are fixedly welded to both side walls of the testing platform 1. A fixing plate 6 is fixedly welded to the top of each pair of L-shaped mounting rods 5. Multiple equidistant first rotating columns 7 are rotatably installed on the inner wall of the fixing plate 6 through bearings. The multiple first rotating columns 7 are concentrically arranged with the multiple semicircular grooves 3. A clamping seat 8 is fixedly welded to the first rotating column 7. A stud 9 is threadedly connected to the top wall of the clamping seat 8 through a threaded hole. A clamping block 10 is installed at the bottom end of the stud 9.

[0022] A first gear 11 is fixedly installed on the first rotating column 7. Multiple second rotating columns 12 are equidistantly distributed on the inner wall of the fixed plate 6 via bearings. The second rotating columns 12 are located below the middle of two adjacent first rotating columns 7. A second gear 13 is fixedly installed on the second rotating column 12. The second gear 13 is meshed with the two first gears 11 located above it. The multiple first rotating columns 7 can rotate synchronously through the cooperation of the multiple second rotating columns 12, the second gears 13 and the first gears 11.

[0023] A dual-axis motor 14 is fixedly installed on the rear side wall of the testing platform 1. Rotary rods 15 are fixedly welded to the two output shafts of the rotating shaft motor 14, and a third gear 16 is fixedly installed on the outer ends of the two rotating rods 15.

[0024] The outer ends of the two first rotating columns 7 located at the rear are fixedly welded with connecting rods 17. The outer ends of the connecting rods 17 are fixedly installed with fourth gears 18. The two fourth gears 18 are respectively meshed with two third gears 16. The dual-shaft motor 14 can drive the two rotating rods 15 to rotate after starting. The two rotating rods 15 can synchronously drive the two connecting rods 17 to rotate through the meshing connection of the third gears 16 and the fourth gears 18, thereby realizing the driving of multiple first rotating columns 7.

[0025] A controller 19 is fixedly installed on the front side wall of the testing platform 1. The controller 19 is electrically connected to multiple arc-shaped heating plates 4 and a dual-axis motor 14 via wires.

[0026] Working Principle: In use, the two ends of multiple cables requiring heat resistance testing are placed sequentially in two rows of clamping seats 8. By turning the studs 9 in the forward direction, the clamping blocks 10 are clamped to the clamping seats 8, thus securing the cable ends. After that, the cover plate 2 is closed, and the controller 19 heats the cables using multiple arc-shaped heating plates 4. Simultaneously, the controller 19 starts the dual-axis motor 14, which drives two rotating rods 15 to rotate. The two rotating rods 15 are connected by the meshing of the third gear 16 and the fourth gear 18, which synchronously drives the two connecting rods 17 to rotate, thereby rotating the two first rotating columns 7 on the rear side. Through the cooperation of multiple second rotating columns 12, second gears 13 and first gears 11, the multiple first rotating columns 7 rotate synchronously, thereby driving the multiple clamped cables to rotate. This achieves uniform heating of multiple cables, facilitating the simultaneous heat resistance testing of multiple cables and greatly improving the efficiency of cable testing.
