DETAILED DESCRIPTION

[0028] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

It should also be understood that although the first, second, third and other numbered adjectives may be used herein to describe various components or parts, these components or parts should not be limited by these adjectives. In other words, these adjectives are only used to distinguish one from another. For example, the first component may also be called the second component, but this does not deviate from the essential technical solution of the present invention. In addition, the terms "and / or" and "and / or" refer to all combinations including any one or more of the listed items.

[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0031] Figure 1 A schematic diagram of the structure of a vehicle-mounted substation maintenance platform in the unloading / assembly state provided in one embodiment of the present application is shown as follows: Figure 1 As shown, the vehicle-mounted substation maintenance platform includes: a support frame 10, an upper frame 20, and a standing platform 21. One end of the upper frame 20 is rotatably connected to one end of the support frame 10, and the upper frame 20 and the support frame 10 can rotate relative to each other. Self-locking rollers 30 are provided on the contact surfaces of the upper frame 20 and the support frame 10 with the car 00. A climbing ladder 80 is also detachably provided on the side of the upper frame 20. One end of the climbing ladder 80 is rotatably connected to the edge of the standing platform 21, and the other end can rotate around the standing platform 21.

[0032] Figure 2 A schematic diagram of an on-board substation maintenance platform in an upright state provided in one embodiment of the present application is shown in FIG. Figure 2 As shown, the other end of the support frame 10 slides toward the outside of the carriage 00 via the self-locking roller 30, rotates toward the ground, and is then vertically fixed to the ground. The end of the upper frame 20 connected to the support frame 10 rotates toward the support frame 10 and is then vertically fixed above the support frame 10. The standing platform 21 is fixedly provided on the top of the upper frame 20. Preferably, after the upper frame 20 is vertically fixed above the support frame 10, mutually matching latch holes are provided on the contact edges, and latches are inserted into the latch holes of the support frame 10 and the upper frame 20 to further fix it.

[0033] The support frame 10 is provided with a retractable self-locking roller 30 (not shown in the figure) on the contact surface with the ground. When not in use, it retracts into the inside of the support frame 10. After locking, the support frame 10 cannot be moved, making the maintenance platform more stable; when the maintenance platform needs to be moved, the self-locking roller 30 is extended through the internal hydraulic rod support, and four retractable self-locking rollers 30 are respectively provided at the four corners of the support frame 10.

[0034] The length of the climbing ladder 80 is greater than the combined length of the upper frame 20 and the support frame 10. Therefore, when the maintenance platform is in an upright position, the climbing ladder 80 can be leaned against one side of the upper frame 20, and the other end of the climbing ladder 80 is grounded. The grounding end is provided with a non-slip pad, which facilitates workers to climb onto the standing platform 21. One end of the upper frame 20 is rotatably connected to one end of the support frame 10 via a tilt shaft 50. That is, one end of the upper frame 20 is coaxially connected to one end of the support frame 10 and can rotate independently.

[0035] Figure 3 This is a structural diagram of a fixing block 60 provided in one embodiment of the present application. A fixing block 60 is fixedly provided on the surface of the carriage 00. Figure 3 As shown, the fixed block 60 is an I-shaped structure with a partition plate 61 vertically arranged in the middle. The two sides of the partition plate 61 are hollow structures. The fixed block 60 can be integrally formed to prevent the partition plate 61 from breaking with the upper and lower plates. Preferably, there are two fixed blocks 60, and they are symmetrically arranged in the carriage 00.

[0036] Figure 4 Provided for an embodiment of this application Figure 1 The top view of the fixing block 60, the clamping member 40, and the rotation limiting member 12 is as shown in FIG. Figure 4 As shown, the fixed block 60 is detachably connected with a clamping member 40, and the clamping member 40 includes a clamping claw 41 and a sliding arm 42. One end of the clamping claw 41 is fixedly connected to the sliding arm 42. The sliding arm 42 is provided with an axial hole 43, and the flip shaft 50 passes through the axial hole 43 and is rotatably connected to the sliding arm 42.

[0037] Figure 5 This is a schematic diagram of the structure of the clamping claw 41 provided in one embodiment of the present application, as shown in FIG. Figure 5 As shown, the clamping claw 41 is provided with a slot 411, through which the partition plate 61 is inserted. Figure 1 and Figure 4 The sliding arm 42 is disposed below the tilt shaft 50 and extends to the upper surface of the support frame 10. This prevents the support frame 10, which has been erected on the ground, from tilting upward, further securing the support frame 10. Furthermore, the clamping member 40 can move along the axis of the tilt shaft 50, thereby enabling the clamping member 40 to engage with or disengage from the fixing block 60. Preferably, the number of the clamping members 40 is the same as the fixing block 60, and their positions correspond one to one.

[0038] Continue to refer to Figure 4 The flip shaft 50 includes a baffle 51 and a return spring 70. The baffle 51 is arranged at the center of the flip shaft 50 and plays a limiting role when the clamping member 40 moves along the axis of the flip shaft 50. The return spring 70 is arranged between the baffle 51 and the sliding arm 42, and is sleeved on the outer periphery of the flip shaft 50. When the clamping member 40 is separated from the fixed block 60, the flip shaft 50 is reset.

[0039] Figure 6 A schematic diagram of another vehicle-mounted substation maintenance platform structure provided in one embodiment of the present application is shown as follows: Figure 6 As shown, a telescopic rod 90 is provided between the upper frame 20 and the support frame 10. The two ends of the telescopic rod 90 are connected to the upper frame 20 and the support frame 10 respectively through pins. The telescopic rod 90 can be a manual or automatic hydraulic cylinder, which drives the upper frame 20 to flip.

[0040] Preferably, see Figure 4 A sliding base 11 is fixedly provided at one end of the support frame 10, and a limited rotation member 12 is slidably connected to the sliding base 11. The limited rotation member 12 slides along the sliding base 11 to above the sliding arm 42 of the clamping member 40. The limiting channel 121 of the limited rotation member 12 is a non-closed chamber, which wraps the outer periphery of the sliding arm 42, limiting the support frame 10 from rotating in the opposite direction around the flip axis 50, and preventing the support frame 10 from reversing under the driving force of the telescopic rod 90.

[0041] The support frame can be made of stainless steel or a composite material that is not easily deformed, wear-resistant and lightweight.

[0042] When not in use, the support frame 10 and the upper frame 20 lie flat on the carriage 00. Figure 1 In the transition state, the upper frame 20 lies flat on the carriage 00, and the support frame 10 slides out of the carriage 00 via the self-locking rollers 30 and rotates downward to stand on the ground. Subsequently, the clamping claw 41 of the clamping member 40 is inserted into the partition plate 61 of the fixed block 60 to prevent the support frame 10 from moving. At the same time, the flip shaft 50 is inserted into the shaft hole 43 of the clamping member 40, and then the rotation limiter 12 is slid along the sliding base 11 to above the sliding arm 42 of the clamping member 40 to prevent the support frame 10 from reversing when the upper frame 20 is flipped. The upper frame 20 is flipped manually or by the hydraulic telescopic rod 90 so that the upper frame 20 and the support frame 10 are in an upright state, and the latch is inserted into the latch holes of the support frame 10 and the upper frame 20. After further fixation, after the assembly is completed, the rotation limiter 12 is slid along the sliding base 11 from above the sliding arm 42 of the clamping member 40 to the initial position, and the two clamping members 40 are moved toward the center along the flip axis 50 to disengage the clamping member 40 from the fixed block 60, so that the maintenance platform can be moved off the vehicle, and the climbing ladder 80 is rotated and fixed to the ground at one end. The staff can climb onto the standing platform 21 from the climbing ladder 80 to work. At the same time, the support frame 10 is provided with a self-locking roller on the contact surface with the ground to facilitate the fixing or movement of the maintenance platform.

[0043] In the solution provided in the embodiment of the present application, the maintenance platform is composed of a support frame and an upper frame. The support frame and the upper frame can be flipped relative to each other. The support frame is flipped and stands on the ground. After the support frame is flipped and placed on the upper frame, the support frame and the upper frame are in a vertical state to complete the assembly, which is convenient for maintenance personnel to move the large maintenance platform on / off the vehicle. At the same time, self-locking rollers are provided on the contact surface between the support frame and the ground, which is convenient for fixing or moving the maintenance platform, thereby improving maintenance efficiency.

[0044] In the description of the present invention, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "the other end", "upper", "one side", "top", "inside", "front", "center", "both ends", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
