[0016] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0017] 1. An operating table is set on the top of the test platform. The tabletop of the operating table is tilted in the left and right directions, and the front side of the tabletop is higher than the back side to prevent the accidental slipping of instruments or tools during the debugging operation and ensure the safe use of the equipment. A vertical board is set on the back side of the tabletop, which is used to support the instruments and equipment, and a through groove is opened on the upper part to facilitate the threading operation of the test cable, ensure the smooth arrangement of the cables, and reduce the entanglement and confusion between the cables.

[0018] 2. When walking on the normal ground, the moving assembly is located in the upper groove, and the test platform moves by the running wheels. When encountering the wire groove, the mandrel moves in the slide groove to make the guide rail slide into the lower groove. At this time, the guide rail extends forward and straddles the wire groove. The guide wheel moves on the guide rail, replacing the running wheel to cross the wire groove, so that the test platform can smoothly pass through the wire groove obstacle, ensuring the smooth movement of the test platform in complex field environments.

[0019] 3. The guide groove is used to constrain the moving direction of the guide wheel to prevent the test platform from slipping during movement, ensuring the stability and safety of the test platform when crossing the cable trough.

[0020] 4. Through the cooperation of the outer baffle, the inner baffle and the rotating plate, it is convenient for the operator to adjust the position of the guide rail when crossing the wire trough to ensure that the platform can smoothly cross the obstacle. When walking on the normal ground, it can effectively limit the sliding of the guide rail in the front and back, left and right directions to ensure the stability of the platform.

[0021] 5. The bottom end of the T-type limit block is exposed from the bottom of the square tube under the action of gravity, and is against the front side of the wire slot to prevent the guide rail from moving forward when the test platform is moved. This design can effectively prevent the guide rail from slipping forward during the movement of the test platform, ensuring the safety and stability of the platform when crossing obstacles.

[0040] Example 2

[0041] The construction and commissioning of a substation is a complex process, involving cross-operation of multiple disciplines and stages. In order to ensure the continuity of the project progress and commissioning work, and to ensure that the substation can be put into operation as planned to meet the needs of power grid operation, in some cases, it is necessary to start the commissioning work when some areas have not been fully completed. This leads to the fact that the commissioning site is often complicated, such as various obstacles such as small debris piled on the road and uncovered cable ducts 8, which cause great inconvenience to the movement of the test platform.

[0042] The obstacles of debris can be cleared to create a passage for the test platform to move, but it is difficult to cross the wire trough 8, and the cables in the wire trough 8 cannot be crushed. When encountering this problem, it is generally necessary to find a suitable wooden board or steel plate on site, but since the test platform, especially the instruments on the platform, are heavy, it is difficult to find a suitable board, and the thick board forms a step between the board and the ground, which makes the board move when the platform moves, making it difficult to operate. Therefore, the instrument is often taken off the platform on site, and two operators lift the test platform over the wire trough 8, then install the instrument on the platform, and debug the switch cabinet on the other side of the wire trough 8 for testing.

[0043] Based on this, in this embodiment, on the basis of embodiment 1, a cross-slot device 7 is provided at the bottom of the outer frame 1, such as Figure 3 As shown, the cross-slot device 7 includes a fixed component 71 and a moving component 72. Figure 4 As shown, the fixing assembly 71 includes a fixing plate 711 and a guide wheel 712. The fixing plate 711 includes a top plate and a side plate. The top plate and the side plate form a U-shape. The guide wheel 712 is installed on the lower side of the top plate. The inner side of the side plate is provided with a slide groove 713. The slide groove 713 includes an upper groove and a lower groove that are connected. Figure 5 As shown, the moving assembly 72 includes a core shaft 721 and a guide rail 722 . Both ends of the core shaft 721 are slidably mounted in the slide groove 713 , and the guide rail 722 is slidably mounted on the core shaft 721 .

[0044] When walking on the ground normally, the moving assembly 72 is located in the upper groove, and the test platform moves through the running wheels 6. When encountering the wire groove 8, the core shaft 721 moves in the slide groove 713, so that the guide rail 722 slides into the lower groove. At this time, the guide rail 722 extends forward and straddles the wire groove 8. The guide wheel 712 moves on the guide rail 722, replacing the running wheels 6 to cross the wire groove 8, so that the test platform can smoothly pass through the wire groove 8 obstacle, ensuring the smooth movement of the test platform in complex field environments.

[0045] like Figure 4 As shown, the upper groove and the lower groove are arranged horizontally, the lower groove extends from one end of the side plate to the other end and is not open at both ends, the length of the upper groove is shorter than the length of the lower groove, the upper groove and the lower groove are connected through a vertical groove, the upper groove and the vertical groove form an L-shaped groove, and the side plate is provided with four groups of L-shaped grooves, which are symmetrically arranged on the side plate, and the openings of the L-shaped grooves face the center. Through the cooperation of the lower grooves that are connected front and back and the L-shaped grooves that are symmetrically arranged front and back, the test platform can cross the wire groove 8 from the front and back directions.

[0046] like Figure 5 As shown, the guide rail 722 includes a square tube and a convex strip, the convex strip is arranged on the square tube, and is used to strengthen the structural strength of the guide rail 722. A guide groove 724 is arranged on the top of the square tube, and the guide wheel 712 can move along the guide groove 724. The guide groove 724 constrains the moving direction of the guide wheel 712 to prevent the test platform from slipping during movement, thereby ensuring the stability and safety of the test platform when crossing the wire groove 8.

[0047] like Figure 5As shown, the core shaft 721 has two parallel shafts, bearings are arranged at both ends of the two core shafts 721, and an outer baffle 726 is arranged inside the bearing, and the outer baffle 726 is fixed on the core shaft 721, and the outer baffle 726 is located outside the guide rail 722. Through the arrangement of the outer baffle 726, when the guide rail 722 slides outward to the outer baffle 726, the guide groove 724 of the guide rail 722 is just aligned with the guide wheel 712, so that the operator can adjust the position of the guide rail 722 to ensure that the platform can smoothly cross the obstacle.

[0048] The core shaft 721 is also provided with an inner baffle 725, which is fixedly mounted on the core shaft 721, and the inner baffle 725 and the outer baffle 726 are located on both sides of the guide rail 722. The end of the fixed plate 711 is rotatably mounted with a rotating plate 714, for example, the rotating plate 714 is mounted on the end of the fixed plate 711 by screws, and the rotating plate 714 can be rotated downward to abut against the end surface of the guide rail 722 (such as Figure 6 When walking on a normal ground, the two guide rails 722 are slid from the left and right sides to the middle, and then the moving assembly 72 is pushed upward and backward, as shown in FIG. Figure 6 As shown, at this time, the left and right movement of the guide rail 722 is limited by the inner baffle plate 725 and the fixing seat of the guide wheel 712, and the rotating plate 714 is rotated downward to limit the front and rear movement of the guide rail 722.

[0049] like Figure 5 As shown, a limiting groove 723 is provided at one end of the square tube, and the limiting groove 723 passes through the tube wall at the lower end of the square tube. A T-shaped limiting block 727 is installed in the limiting groove 723, and the bottom end of the T-shaped limiting block 727 is exposed from the bottom of the square tube under the action of gravity. Figure 8 As shown, the front side of the guide rail 722 is pressed against the line slot 8 to prevent the guide rail 722 from moving forward when the test platform is moved. Through this design, the guide rail 722 can be effectively prevented from slipping forward during the movement of the test platform, ensuring the safety and stability of the platform when crossing obstacles.

[0050] Test platform moving process:

[0051] When moving on normal ground, Figure 6 As shown, the guide rail 722 is located in the upper groove of the slide groove 713. The movement of the guide rail 722 in the left and right directions is limited by the inner baffle plate 725 and the fixed seats on both sides of the guide wheel 712. The movement of the guide rail 722 in the front and rear directions is limited by the rotating plate 714. At this time, the walking wheel 6 is used to move on the ground.

[0052] When encountering the wire slot 8, first rotate the rotating plate 714 to the horizontal direction (such as Figure 7As shown in FIG. 1 ), the guide rail 722 is pulled forward, and the bearings at both ends of the core shaft 721 first move forward in the upper groove, slide through the vertical groove and slide into the lower groove, and then slide the guide rail 722 to the left and right sides so that the guide rail 722 rests on the outer baffle 726. At this time, the guide wheel 712 is aligned with the guide wheel 712, and the protruding part of the guide rail 722 straddles the line groove 8 (as shown in FIG. 1 ). Figure 8 As shown in the figure, the limit block is blocked on the front end surface of the wire groove 8 under the action of gravity, and the test platform is pushed forward at this time, the guide wheel 712 moves on the guide rail 722, and the walking wheel 6 passes through the wire groove 8 on the plane of the wire groove 8. When the test platform crosses the wire groove 8, part of the guide rail 722 is located at the rear side of the test platform. First, the guide rail 722 is slid to the middle and leaned against the inner baffle 725, and then moved upward into the upper groove, and then pushed inward (forward) to push the guide rail 722 into the test platform, and finally the rear side rotating plate 714 is rotated to the lower side to complete the crossing of the wire groove 8.

[0053] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
