Technical Field
[0001] This utility model relates to the field of pantograph testing equipment, specifically to a mobile pantograph testing platform. Background Technology
[0002] The pantograph is an electrical device used by electric locomotives to obtain power from the overhead contact line. It requires regular lifespan testing and performance checks to maintain safe and stable operation and prevent accidents. Existing pantograph testing equipment generally includes a support frame for the pantograph, a drive unit for measuring parameters such as pantograph raising and lowering time, pressure, and height, and an operating platform. Existing testing equipment is generally a fixed structure. For example, invention patent application number "202111044727.6," entitled "Pantograph Performance and Fatigue Testing Device," filed by Hunan Runwei Intelligent Machinery Co., Ltd., discloses a fixed-structure pantograph testing device. During testing, the equipment needs to be transported to the train. The fixed structure suffers from the drawbacks of being difficult to move and inconvenient to transport, affecting testing efficiency. Utility Model Content
[0003] To address the shortcomings of existing pantograph testing equipment, such as difficulty in moving and inconvenience in transportation, this utility model provides a mobile pantograph testing platform that solves the above problems.
[0004] A mobile pantograph test stand includes a support base, a drive box, an operating table, and a limiting frame. Multiple rollers are provided at the bottom of the support base, the drive box, and the operating table. Multiple supports are vertically arranged on the support base. The drive box and the operating table are both placed on the support base. The outer side of the limiting frame abuts against multiple supports simultaneously, and the inner side abuts against the side walls of the drive box and the operating table simultaneously.
[0005] In a preferred embodiment of the mobile pantograph test stand provided by this utility model, the limiting frame, the drive box, and the operating table are all provided with one or more handles.
[0006] In a preferred embodiment of the mobile pantograph test stand provided by this utility model, the support base is a square plate with four rollers at the four corners of the bottom and four supports vertically arranged at the four corners of the top. The top of the support is provided with a pantograph connector.
[0007] In a preferred embodiment of the mobile pantograph test stand provided by this utility model, the limiting frame is a square plate with notches at the four corners to connect with the four supports, and two notches in the middle to connect with the drive box and the operating table respectively.
[0008] The bracket has a pin in the middle section; the limiting frame rests on the pin. A buffer pad is provided inside the middle notch to abut against the drive box and the operating table. The limiting frame has movable baffles on the outer sides of the two middle notches.
[0009] Compared with existing technologies, the mobile pantograph testing platform provided by this utility model has the following advantages:
[0010] 1. In this utility model, the support base, drive box and the bottom of the operating table are all equipped with rollers, which facilitates movement at the test site and makes it convenient to quickly test each pantograph.
[0011] 2. In this utility model, the drive box and the operating table are placed on the support base, which reduces the overall size. At the same time, the support base is used as a flatbed cart, which facilitates movement and transportation.
[0012] 3. This utility model is equipped with a limit plate to stably restrict the drive box and the operating table between the support base, so as to avoid damage caused by shaking during the movement and transportation of the equipment. Attached Figure Description

[0016] The following components are labeled in the diagram: bracket 1, drive box 2, operating table 3, limit frame 4, handle 5, base plate 11, bracket 12, bracket base roller 13, pantograph connector 14, pin 15, drive box roller 21, operating table roller 31, movable plate 41. Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1:
[0018] Please also refer to Figure 1 and Figure 2 These are schematic diagrams of the mobile pantograph test stand provided by this utility model, and schematic diagrams of the stand after removing the drive box and the control panel.
[0019] The mobile pantograph test stand includes a support base 1, a drive box 2, an operating table 3, and a limit frame 4.
[0020] The support base 1 includes a base plate 11, a support 12, and support rollers 13. The support base 1 is a rectangular flat plate with support rollers 13 at each of its four bottom corners and a support 12 vertically positioned at each of its four top corners. The main structure of the support 12 is a channel steel, with an end plate welded to each end. The bottom end plate is used to connect to the base plate 11, and the top end plate is used to install the pantograph connector 14. A hole is drilled in the middle of the channel steel, and a pin 15 is provided.
[0021] The drive box 2 is identical to similar products in the prior art, except that it has drive box rollers 21 at the four corners of its bottom. The control panel 3 is identical to similar products in the prior art, except that it has control panel rollers 31 at the four corners of its bottom.
[0022] The limiting frame 4 is a rectangular flat frame with L-shaped support arms at each of the four corners, which connect to the four supports 12 respectively. There are two square notches in the middle, which connect to the drive box 2 and the operating table 3 respectively. The two middle notches are slightly larger than the drive box 2 and the operating table 3, and rubber pads are provided on the inside of the notches to fill the gaps between them and provide cushioning.
[0023] In use, place the drive box 2 and the control panel 3 onto the base plate 11 using the handles 5 on the drive box 2 and the control panel 3. Place the limit plate 4 between the four supports 12 using the handles on the limit plate 4. Tilt it slightly to avoid the end plates at the top of the supports 12, and at the same time, fine-tune the positions of the drive box 2 and the control panel 3 so that they pass exactly through the notch. Finally, place the limit plate 4 onto the pin 15.
[0024] After moving to the test position, remove the limit plate 4 and move the drive box 2 and operating platform 3 to the ground. Test the pantograph according to the standard procedure. Example 2:
[0025] Please see Figure 3 This is a schematic diagram of the structure in this embodiment where the drive box and the control panel are removed.
[0026] The difference from Example 1 is as follows:
[0027] The front and rear ends of the limiting frame 4 are connected to the main structure of the limiting frame 4 by a side plate close to the two gaps in the middle. This side plate is referred to as the movable plate 41.
[0028] One end of the movable plate 41 is rotatably connected to the main structure of the limiting frame 4 via a hinge, and the other end is a stepped structure that rests on the main structure of the limiting frame 4 and is fixed with a pin.
[0029] During use, the main structure of the limit frame 4 remains resting on the pin 15. Remove the pin at the end of the movable plate 41, rotate the movable plate 41 to open it, and then you can place and remove the drive box 2 and the operating table 3. The limit frame 4 can also be removed if it interferes with the test operation.
[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
