Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet commissioning technology, and in particular to a conveniently movable electrical cabinet test cart. Background Technology

[0002] Electrical cabinets are made of steel and are used to protect components and ensure their proper functioning. The materials used in electrical cabinet manufacturing are generally divided into hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are lighter and more flexible than hot-rolled steel plates, making them more suitable for electrical cabinet manufacturing. In the fields of power systems and industrial automation, the commissioning and maintenance of electrical cabinets are crucial. The test cart, as a key tool to assist in the commissioning of the internal equipment of the electrical cabinet, directly affects work efficiency and safety due to its mobility and testing performance. Therefore, improvements and advancements in the use of electrical cabinet test carts are necessary.

[0003] Currently, most electrical cabinet testing carts on the market simply install testing devices to visually test the circuit connectivity of the electrical cabinet. However, in actual use, testing the electrical cabinet requires many wires to be connected to the cart, which are messy and drag on the ground. The wire winding and protection capabilities are also insufficient, resulting in poor practicality. Therefore, we propose a mobile electrical cabinet testing cart to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a conveniently movable electrical cabinet test cart.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable electrical cabinet test cart includes a test cart body and cables. The test cart body is symmetrically equipped with a cable winding mechanism. The cable winding mechanism includes a first cable winding support plate and a second cable winding support plate. A cable winding rotating rod is rotatably connected between the first cable winding support plate and the second cable winding support plate. A reciprocating cable routing threaded block is provided between the first cable winding support plate and the second cable winding support plate. The reciprocating movement of the cable routing threaded block is used for uniform cable winding.

[0007] A tightening assembly is provided between the first take-up support plate and the second take-up support plate. The tightening assembly includes a sliding plate and a sliding table, which can move up and down. Tightening rollers are symmetrically installed between the sliding plate and the sliding table. A slotted rod is rotatably connected between the first take-up support plate and the second take-up support plate. A tightening buckle is slidably provided on the slotted rod. A connecting block that is rotatably connected to the tightening buckle is fixedly connected to the cable thread block. The tightening roller and the tightening buckle are used for tightly taking up the cable.

[0008] The above technical solution further includes:

[0009] The take-up mechanism also includes a drive sprocket, which is fixedly connected to one end of the take-up rotating rod extending to the outside of the second take-up support plate. A reciprocating screw is rotatably connected between the first take-up support plate and the second take-up support plate. A driven sprocket is fixedly connected to one end of the reciprocating screw near the drive sprocket. A chain is sleeved between the drive sprocket and the driven sprocket.

[0010] A sliding rod is fixedly connected between the first take-up support plate and the second take-up support plate. The sliding rod slides relative to the cable thread block. The reciprocating screw is threadedly connected to the cable thread block. The cable passes through the slot hole opened at the top of the cable thread block.

[0011] The tightening assembly also includes a wire pressing rotating rod, which is rotatably connected to the first wire take-up support plate. An active bevel gear is fixedly connected to the outer side of the wire pressing rotating rod, and the slot rod is fixedly connected to the wire pressing rotating rod.

[0012] The sliding table is slidably disposed in a groove opened in the first take-up support plate. A threaded rod is rotatably connected to the side of the first take-up support plate near the sliding table. The threaded rod is threadedly connected to the sliding table. A driven bevel gear is fixedly connected to the end of the threaded rod near the wire pressing rotating rod. The driven bevel gear meshes with the driving bevel gear.

[0013] The sliding plate is slidably disposed in a groove opened on the second take-up support plate, and a guide rod is fixedly connected to the inner side of the groove, and the guide rod slides relative to the sliding plate.

[0014] The card slot rod has a limiting groove, the tightening buckle is slidably disposed on the limiting groove, and bearings that slide relative to the limiting groove are fixedly connected to both sides of the tightening buckle. The bearings are rotatably connected to the connecting block, and the cable is disposed between the two tightening rollers and passes through the slot hole opened on the tightening buckle.

[0015] The top of the test vehicle body is fixedly connected to a mounting support plate. A detection cavity and a vehicle control box are mounted on the mounting support plate. The second take-up support plate and the first take-up support plate are fixedly connected to the mounting support plate. A detection lamp and a detection motor are installed inside the detection cavity.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, the reciprocating movement design of the cable thread block ensures that the cable is evenly wound around the winding rotating rod during the winding process. This even winding method avoids excessive accumulation or uneven winding of the cable in a certain position, facilitating subsequent locating, organizing, and replacement of the cable.

[0018] In this invention, the tightening roller and tightening buckle in the tightening assembly cooperate with each other. The friction between the tightening roller and the tightening buckle is used to tighten the cable during the winding process, reducing the gaps between the cables and preventing the cables from loosening, thereby ensuring that the cables are tightly wound on the winding rotating rod.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] like Figures 1-6As shown, the present invention proposes a conveniently movable electrical cabinet test cart, which includes a test cart body 1 and a cable 9. The test cart body 1 is symmetrically provided with a take-up mechanism, which includes a first take-up support plate 5 and a second take-up support plate 10. A take-up rotating rod 50 is rotatably connected between the first take-up support plate 5 and the second take-up support plate 10. A reciprocating cable thread block 51 is provided between the first take-up support plate 5 and the second take-up support plate 10. The reciprocating movement of the cable thread block 51 is used to evenly take up the cable 9.

[0029] A tightening assembly is provided between the first take-up support plate 5 and the second take-up support plate 10. The tightening assembly includes a sliding plate 65 and a sliding table 6. The sliding plate 65 and the sliding table 6 can move up and down. Tightening rollers 67 are symmetrically installed between the sliding plate 65 and the sliding table 6. A slot rod 62 is rotatably connected between the first take-up support plate 5 and the second take-up support plate 10. A tightening buckle 68 is slidably provided on the slot rod 62. A connecting block 506 that is rotatably connected to the tightening buckle 68 is fixedly connected to the cable thread block 51. The tightening roller 67 and the tightening buckle 68 are used to tightly take up the cable 9.

[0030] Furthermore, during the operation of the electrical cabinet test cart, when it is necessary to take in the cable 9, firstly, the take-in rotating rod 50 is rotated to drive the cable thread block 51 to reciprocate between the first take-in support plate 5 and the second take-in support plate 10. The reciprocating movement of the cable thread block 51 can guide the cable 9 to be evenly wound on the take-in rotating rod 50, avoiding excessive accumulation of the cable 9 at a certain position on the take-in rotating rod 50, and ensuring that the cable 9 is evenly distributed on the take-in rotating rod 50.

[0031] Furthermore, during the winding process, the sliding plate 65 and the sliding table 6 can move up and down between the first winding support plate 5 and the second winding support plate 10. The height of the sliding plate 65 and the sliding table 6 is adjusted according to the tightness of the cable 9. The cable 9 is wound between the tightening rollers 67. During the winding process, the tightening rollers 67 apply friction to the cable 9. This friction will generate a force that hinders the free movement of the cable 9, which is equivalent to applying a tension force to the cable 9, so that the cable 9 is tensioned during the winding process.

[0032] Furthermore, the tightening buckle 68 is rotatably connected to the connecting block 506 fixedly connected to the cable thread block 51. During the reciprocating movement of the cable thread block 51, the connecting block 506 moves along with it, causing the tightening buckle 68 to slide on the slot rod 62. The angle of the tightening buckle 68 is adjustable. During sliding, the tightening buckle 68 contacts the cable 9, further restricting the movement of the cable 9 and increasing the friction between the cable 9 and the tightening buckle 68. The combined friction generated by the tightening roller 67 and the tightening buckle 68 ensures that the cable 9 remains taut during winding, reducing gaps between cables and preventing the cable 9 from becoming loose during winding.

[0033] The take-up mechanism also includes a drive sprocket 54, which is fixedly connected to one end of the take-up rotating rod 50 extending to the outside of the second take-up support plate 10. A reciprocating screw 53 is rotatably connected between the first take-up support plate 5 and the second take-up support plate 10. A driven sprocket 56 is fixedly connected to one end of the reciprocating screw 53 near the drive sprocket 54. A chain 55 is sleeved between the drive sprocket 54 and the driven sprocket 56.

[0034] A slide rod 52 is fixedly connected between the first take-up support plate 5 and the second take-up support plate 10. The slide rod 52 slides relative to the cable thread block 51. The reciprocating screw 53 is threadedly connected to the cable thread block 51. The cable 9 passes through the slot hole opened at the top of the cable thread block 51.

[0035] Furthermore, firstly, a handle is installed on the take-up rotating rod 50. When the handle is turned, causing the take-up rotating rod 50 to rotate, the drive sprocket 54 will rotate synchronously. Since a chain 55 is sleeved and connected between the drive sprocket 54 and the driven sprocket 56, the rotation of the drive sprocket 54 will transmit power to the driven sprocket 56 through the chain 55, thereby driving the reciprocating screw 53, which is fixedly connected to the driven sprocket 56, to rotate together.

[0036] Furthermore, a sliding rod 52 is fixedly connected between the first take-up support plate 5 and the second take-up support plate 10. The threaded block 51 slides relative to the sliding rod 52, and the threaded block 51 is threadedly connected to the reciprocating screw 53. The sliding rod 52 limits the threaded block 51, preventing it from rotating with the reciprocating screw 53, and instead allowing it to reciprocate linearly along the axis of the sliding rod 52. The cable 9 passes through the slot at the top of the threaded block 51, and during the reciprocating movement of the threaded block 51, it guides the cable 9 to be evenly wound around the take-up rotating rod 50.

[0037] Specifically, when the reciprocating screw 53 rotates, the cable guide thread block 51 moves back and forth along the axis of the slide bar 52 under the action of the threaded connection. As the cable 9 rotates to take in the cable, the cable guide thread block 51 moves back and forth, allowing it to be neatly and evenly wound layer by layer on the take-up rotating rod 50. This prevents the cable 9 from being excessively piled up at a certain position on the take-up rotating rod 50, ensuring the uniformity and neatness of the cable 9 being taken in.

[0038] The tightening assembly also includes a wire pressing rotating rod 60, which is rotatably connected to the first wire take-up support plate 5. An active bevel gear 61 is fixedly connected to the outer side of the wire pressing rotating rod 60, and a slot rod 62 is fixedly connected to the wire pressing rotating rod 60.

[0039] The sliding table 6 is slidably disposed in the groove 611 opened on the first take-up support plate 5. A threaded rod 64 is rotatably connected to the side of the first take-up support plate 5 near the sliding table 6. The threaded rod 64 is threadedly connected to the sliding table 6. A driven bevel gear 63 is fixedly connected to the end of the threaded rod 64 near the wire pressing rotating rod 60. The driven bevel gear 63 and the driving bevel gear 61 mesh with each other.

[0040] The sliding plate 65 is slidably disposed in the groove 611 opened on the second take-up support plate 10. A guide rod 66 is fixedly connected to the inner side of the groove 611, and the guide rod 66 slides relative to the sliding plate 65.

[0041] A limiting groove 610 is provided on the slot rod 62, and a tightening buckle 68 is engaged and slidably disposed on the limiting groove 610. Bearings 69 that slide relative to the limiting groove 610 are fixedly connected to both sides of the tightening buckle 68. The bearings 69 are rotatably connected to the connecting block 506. The cable 9 is disposed between the two tightening rollers 67 and passes through the slot provided on the tightening buckle 68.

[0042] Furthermore, when the cable is wound up in the easily movable electrical cabinet test cart, the tightening component works in conjunction with the winding mechanism to ensure that the cable 9 is tightly and evenly wound on the winding rotating rod 50. The handle on the driving pressure rotating rod 60 is rotated. Since the pressure rotating rod 60 is rotatably connected to the first winding support plate 5, and the outer side of the pressure rotating rod 60 is fixedly connected to the active bevel gear 61, and the slot rod 62 is fixedly connected to the pressure rotating rod 60, the active bevel gear 61 will rotate synchronously with the pressure rotating rod 60.

[0043] Furthermore, the rotation of the driving bevel gear 61 drives the driven bevel gear 63 to rotate, which in turn causes the threaded rod 64 to rotate. The sliding table 6 is slidably disposed within the groove 611 opened on the first take-up support plate 5, and the threaded rod 64 is threadedly connected to the sliding table 6. When the threaded rod 64 rotates, the sliding table 6 moves up and down along the groove 611. At the same time, when the sliding table 6 moves up and down, it drives the sliding plate 65 and the tightening roller 67 to move up and down synchronously.

[0044] Furthermore, during the winding process of cable 9, by rotating the wire pressing rotating rod 60, the two tightening rollers 67 are adjusted to a certain position, thereby adjusting the distance between the two tightening rollers 67 and the winding rotating rod 50. Cable 9 is placed between the two tightening rollers 67. When cable 9 moves, friction is generated between it and the tightening rollers 67. This friction generates a force that hinders the free movement of cable 9, which is equivalent to applying tension to cable 9, so that cable 9 is initially tensioned during winding.

[0045] Furthermore, when the wire pressing rotating rod 60 is rotated, the wire pressing rotating rod 60 simultaneously drives the slot rod 62 to rotate. Since the tightening buckle 68 is engaged on the slot rod 62, and the tightening buckle 68 is connected to the cable thread block 51 through the connecting block 506, the tightening buckle 68 moves synchronously while the cable thread block 51 moves back and forth. During the rotation of the slot rod 62, the tightening buckle 68 is driven to rotate along the axis of the slot rod 62. During the rotation of the tightening buckle 68, the slot at its top will also rotate and move, and the rotation and movement of the slot will further tighten the cable 9.

[0046] Specifically, when the pressure rod 60 is rotated clockwise, the pressure rod 60 drives the threaded rod 64 to rotate, causing the two tightening rollers 67 to move downwards. At this time, the cable 9 is initially tensioned. At the same time, the pressure rod 60 rotates clockwise, causing the tightening buckle 68 to rotate synchronously, further tensioning the cable 9.

[0047] The top of the test vehicle body 1 is fixedly connected to the mounting support plate 2. The mounting support plate 2 is equipped with the detection chamber 3 and the vehicle control box 4. The second take-up support plate 10 and the first take-up support plate 5 are fixedly connected to the mounting support plate 2. The detection lamp 7 and the detection motor 8 are installed inside the detection chamber 3.

[0048] Furthermore, the test cart body 1 is equipped with casters at the bottom for easy movement and convenient carrying and use of the testing equipment. The testing chamber 3 can be equipped with a testing motor 8 and a testing lamp 7. The output end of the testing motor 8 is equipped with a fan. After the testing motor 8 is connected to the electrical cabinet, it can run automatically. At this time, the fan rotates to detect whether the electrical cabinet is connected. After the testing lamp 7 is electrically connected, the voltage strength of the electrical cabinet can be detected by the brightness of the light from the testing lamp 7. The top of the vehicle control box 4 is equipped with an emergency stop button and an incoming power warning light. The emergency stop button can control the emergency stop, and the incoming power warning light can illuminate to provide a visual warning after the circuit is connected. The multi-mode testing effect is good.

[0049] In this embodiment, the test cart body 1 is equipped with casters at the bottom for easy movement. The detection chamber 3 can install the detection motor 8 and detection lamp 7 to detect the electrical cabinet. The vehicle-mounted control box 4 can perform emergency stop control and power-on warning. The multi-mode detection effect is good. In the operation of the test cart with the conveniently movable electrical cabinet, when it is necessary to take in the cable 9, the entire take-in and tightening process works in tandem. First, rotate the handle on the take-in rotating rod 50 to drive the take-in rotating rod 50 to rotate, thereby driving the reciprocating screw 53 to rotate. Under the rotation of the reciprocating screw 53, the cable thread block 51 moves back and forth along the slide rod 52 axially, guiding the cable 9 to be evenly wound on the take-in rotating rod 50. At the same time, rotate the handle on the pressure rotating rod 60, and the sliding table 6 moves up and down along the slide groove 611, driving the sliding plate 65 and the tightening roller 67 to move synchronously. Adjust the height position of the two tightening rollers 67, and the cable 9 moves between the tightening rollers 67 to generate friction and achieve initial tension. In addition, the wire pressing rotating rod 60 drives the slot rod 62 to rotate, and the rotation of the slot rod 62 causes the tightening buckle 68 to rotate, and the top slot of the buckle rotates and moves to further tighten the cable 9.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
