Description

Technical Field

[0001] The utility model relates to the technical field of power-on test platforms, and particularly relates to a wire winding device for a complete set of multi-functional test platforms. Background Art

[0002] Before the complete sets of products such as high and low voltage switch cabinets leave the factory, electrical commissioning personnel need to use a complete set of multi-functional test platforms to conduct power-on commissioning and inspection on the corresponding products to ensure that the functions and characteristics of the products are qualified before leaving the factory. The power-on test platform is a device that provides various AC and DC power supplies, and is used to detect the electrical performance of electrical equipment such as switch cabinets, including the measurement of parameters such as current, voltage, and frequency, and the action verification of components such as relays and circuit breakers.

[0003] During the commissioning process, the test platform needs to be connected to an external power supply, and the external power supply is converted into AC and DC power supplies with various output voltages and currents, so that electrical commissioning personnel can carry out power-on commissioning work on the complete sets of products to be inspected.

[0004] When the external power supply is far from the complete set of products to be powered on and inspected, a long power cord needs to be equipped to supply power to the test platform. Due to the long power cord, it will increase the wire harness sorting time and reduce the work efficiency of electrical commissioning personnel. At the same time, the test platform is not equipped with a corresponding wire winding device, and the power cord will occupy some site space. Content of the Utility Model

[0005] The utility model provides a wire winding device for a complete set of multi-functional test platforms, which can realize the orderly storage of the power cord of the complete set of multi-functional test platforms, is simple to operate, stable and reliable.

[0025] The following is further detailed through specific implementation manners:

[0026] The marks in the attached drawings of the specification include: roller bar 1, outer wire reel 2, take-up roller 3, inner wire reel 4, foldable handle 5, rotating shaft 6, limit bracket 7, lock plate 8, bearing 9, bearing bracket 10, hook 11.

[0027] Embodiment 1

[0028] In actual use, the complete set of multi-functional test platforms are usually equipped with relatively long AC power input lines for connecting to external AC power sources to achieve flexible layout of the multi-functional test platforms. The AC power input lines require reasonable storage methods to ensure a clean and safe management of the debugging environment.

[0029] This embodiment provides a wire winding device for a complete set of multi-functional test platforms, as Figure 1 shown, which includes a wire winding unit, a rotating shaft unit and a locking unit.

[0030] Among them, the wire winding unit is located outside the side plate of the test platform and includes an outer wire disc 2, an inner wire disc 4 and a wire winding roller 3. The outer wire disc 2 and the inner wire disc 4 are coaxial discs arranged in parallel, and both have openings at the centers. The wire winding roller 3 is respectively connected to the outer wire disc 2 and the inner wire disc 4, and the diameter of the wire winding roller 3 is smaller than that of the outer wire disc 2 and the inner wire disc 4, forming a storage cavity for the power cable bundle. The outer wire disc 2 is provided with a foldable handle 5, and the foldable handle 5 includes a handle sleeve and a handle rotating shaft. The handle sleeve is rotatably connected to one end of the handle rotating shaft to realize rotation during wire winding. The other end of the handle rotating shaft is hinged to the outer wire disc 2, and the handle rotating shaft can rotate around the hinge to realize two states: vertical and parallel. The outer edge of the inner wire disc 4 is provided with a plurality of evenly distributed toothed openings. Both the outer wire disc 2 and the inner wire disc 4 are provided with radially strip-shaped openings evenly distributed along the circumference. The wire winding roller 3 includes roller bars 1 and gears. The roller bars 1 include a plurality of parallel metal bars evenly arranged along the circumference and are fixedly connected to the gears. The two ends of the roller bars 1 are respectively welded to the middle parts of the outer wire disc 2 and the inner wire disc 4.

[0031] The rotating shaft unit includes a rotating shaft 6, a bearing group and a bearing bracket 10. The bearing bracket 10 is welded to the inner wall of the side plate of the test platform, as Figure 2 shown. A bearing group is installed on the bearing bracket 10, and the bearing group includes two coaxially arranged bearings 9. The side plate of the test platform is provided with an opening, and the rotating shaft 6 respectively passes through the outer wire disc 2, the wire winding roller 3, the inner wire disc 4, the side plate opening and the bearing group. There are two round holes on the rotating shaft 6 near the bearing group, and the rotating shaft 6 is fixed by split pins. Through the connection of the rotating shaft, the outer wire disc 2, the wire winding roller 3, the inner wire disc 4 and the rotating shaft 6 can rotate synchronously, as Figure 3 shown.

[0032] The locking unit includes a limit bracket 7 and a locking plate 8, which are used to limit the wire winding unit. The limit bracket 7 is fixedly connected to the side plate of the test platform. The limit bracket 7 is of a cuboid structure, with a U-shaped groove on the outer side and is welded to the side plate of the test platform on the inner side. The limit bracket 7 is provided with two through holes in the vertical direction, and the horizontal projection of the through holes is within the horizontal projection range of the U-shaped groove; the locking plate 8 can move back and forth along the U-shaped groove. When the locking plate 8 moves forward, it can be clamped with the opening of the inner wire reel. There is a strip-shaped opening in the middle of the locking plate 8, and the length of the strip-shaped opening is greater than the sum of the center distance and the diameter of the two through holes, as Figure 4 shown. Push the locking plate 8 backward so that it does not contact the opening of the inner wire reel. At this time, the wire winding unit can rotate freely; align the locking plate 8 with the opening and push it forward into the opening. At this time, the wire winding unit is blocked by the locking plate 8 and cannot rotate.

[0033] In actual use, the tester can rotate the handle to drive the wire winding unit to rotate, realizing the winding of the power cord, which is simple and fast to operate. After the wire harness is wound up, align the opening on the inner wire reel with the locking plate 8 and push the locking plate in. Use a screw to fix the locking plate 8 through the through holes on the limit bracket 7, so as to realize the limit of the wire winding unit and prevent the wound wire harness from becoming loose due to the rotation of the wire winding unit.

[0034] Embodiment 2

[0035] As Figure 5 shown, the test platform is also provided with a wire winding device for winding and arranging the output power cord.

[0036] Since there are many types of output power supplies for the complete set of multifunctional test platforms, including three-phase 380V power supply, standby three-phase 380V power supply, three-phase adjustable voltage power supply, three-phase adjustable current power supply, three-phase socket, single-phase socket, adjustable DC power supply. Accordingly, the number of power cords is large. Without a proper wire winding device, the process of arranging the power cords is rather cumbersome, and there is no suitable storage location for the arranged power cords.

[0037] To meet this requirement, in this embodiment, hooks 11 are added at the rear cabinet door of the test platform for winding the output power cord.

[0038] The rear cabinet door of the test platform is of a double-opening type and is respectively connected to the side plate through door limiters. There is a strip-shaped opening at the lower side of the cabinet door for wire outlet. A pair of parallel hooks 11 are provided inside the upper side of the rear cabinet door. When no power-on test is required, the output power cord can be wound at the hooks 11; when a power-on test is required, take the power cord off the hooks 11 and lead it out through the strip-shaped gap between the rear cabinet door and the bottom plate. In this way, the flexible arrangement of the test platform position can be realized, ensuring the safety of the tester.
