Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pantograph detection, specifically a mobile pantograph detection device. Background Technology
[0002] A pantograph is an electrical device used by electric locomotives to obtain electrical energy from the overhead contact line, and it is installed on the roof of the locomotive or train. Pantographs can be divided into single-arm and double-arm types, both consisting of a sliding plate, upper frame, lower arm (double-arm pantographs use a lower frame), base frame, lifting spring, transmission cylinder, and support insulators. To ensure the stability of the pantograph before it is put into use, performance testing is required during the manufacturing process. Such pantograph testing equipment plays a crucial role in pantograph production.
[0003] However, existing pantograph testing equipment relies on manual operation to contact and connect the testing device to the pantograph. This method prevents the pantograph from moving during testing, thus failing to simulate the power supply situation when a locomotive is in motion. Furthermore, it requires careful installation and securing of the pantograph by personnel to prevent it from shifting when in contact with the testing equipment, increasing the workload of staff and reducing testing efficiency. To address these issues, this design proposes a mobile pantograph testing device. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this invention is to provide a mobile pantograph detection device to solve the issues raised in the background section.
[0005] To achieve the above objectives, this utility model proposes a mobile pantograph detection device, including a detection base, a conveyor, and a mounting mechanism installed on the upper end of the conveyor, wherein the conveyor is installed on the top of the detection base.
[0006] The installation mechanism includes multiple support bases installed on the conveyor. Each support base has a limit groove at each of its four corners. The bottom of the inner wall of each limit groove has a connecting groove. The middle of the inner wall of each support base has an installation groove. The inner wall of each installation groove has a support shaft that slides along it. The outer walls at both ends of each support shaft have two connecting rods that rotate. The inner wall of each limit groove has a clamping plate that slides along it. One end of each connecting rod passes through the inner wall of each connecting groove and rotates to the bottom of each clamping plate. The outer wall of each support shaft passes through the top of the support base and is connected to a pressing shaft.
[0007] In one example, a first spring is fixedly provided on the outer wall of one end of each extrusion shaft, and one end of each first spring is fixedly connected to the upper side of the inner wall of each mounting groove. A gasket is fixedly provided on the top of each extrusion shaft.
[0008] In one example, two annular grooves are formed on the outer walls at both ends of each support shaft, and the outer wall at one end of each connecting rod is slidably connected to the inner wall of each annular groove. An anti-slip pad is fixedly provided on one side of each clamping plate.
[0009] In one example, a detection cover is installed at the middle position of the top of the detection base, and mounting brackets are installed at both ends of the upper side of the inner wall of the detection cover. Multiple detection cables are connected at equal distances between the two mounting brackets.
[0010] In one example, two mounting brackets are inserted at both ends of the top of the two mounting brackets, and a second spring is fitted on the outer wall of one end of each of the four mounting brackets, with one end of each second spring being fixedly connected to both ends of the top of the two mounting brackets respectively.
[0011] In one example, a control panel is fixedly provided on one side of the detection cover, and the conveyor and detection cable are electrically connected to an external power supply through the control panel.
[0012] The mobile pantograph detection device proposed in this utility model can bring the following beneficial effects:
[0013] This mobile pantograph testing device, through its installation mechanism, allows the pantograph to be placed directly on a support base during testing. The pantograph's pressure pads cause it to slide down along the support shaft, bringing the clamping plates closer together under the pull of the connecting rod, thus clamping and fixing the pantograph on both sides. A conveyor then transports the pantographs sequentially into the testing chamber for testing. After testing, the tested pantograph is lifted, and the clamping plates are pushed open by the connecting rod under the elastic action of a first spring, releasing the pantograph from its base and allowing for easy removal. This design reduces the workload of workers, saves time on pantograph installation, and improves testing efficiency. Attached Figure Description

[0020] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0021] The following is an example:
[0022] This utility model provides, for example Figure 1-4 The mobile pantograph detection device shown includes a detection base 1, a conveyor 2, and a mounting mechanism 3 installed on the upper end of the conveyor 2, wherein the conveyor 2 is installed on the top of the detection base 1.
[0023] The mounting mechanism 3 includes multiple support bases 301 mounted on the conveyor 2. Each support base 301 has four limiting grooves 302 at its top corners. Each limiting groove 302 has a connecting groove 303 at the bottom of its inner wall. Each support base 301 has an installation groove 304 at the center of its inner wall. Each installation groove 304 has a slidable support shaft 305 on its inner wall. Each support shaft 305 has two rotatably mounted connecting rods 306 on its outer walls at both ends. Each limiting groove 302 has a sliding clamping plate 307 on its inner wall. One end of each connecting rod 306 passes through the inner wall of each connecting groove 303 and is rotatably connected to the bottom of each clamping plate 307. The outer wall of each support shaft 305 passes through the supporting base 301. The top of the base 301 is connected to the extrusion shaft 308, and the connecting groove 303 on each support base 301 is connected to the inner wall of the mounting groove 304. The support shaft 305 sliding in the mounting groove 304 is rotatably connected to the connecting rod 306. Each connecting rod 306 passes through the inner wall of the connecting groove 303 and is rotatably connected to the bottom of the clamping plate 307 sliding in the limiting slide groove 302. When the support shaft 305 is compressed, the connecting rod 306 can slide the clamping plate 307 closer in the limiting slide groove 302. When the support shaft 305 rises, the clamping plate 307 slides away in the limiting slide groove 302. The outer walls at both ends of the support shaft 305 are limited when sliding with the inner walls on both sides of the mounting groove 304, so that it can remain stable when it rises and falls.
[0024] Furthermore, a first spring 309 is fixedly provided on the outer wall of one end of each extrusion shaft 308, and one end of each first spring 309 is fixedly connected to the upper side of the inner wall of each mounting groove 304. A pad 310 is fixedly provided on the top of each extrusion shaft 308, and when the extrusion pad 310 descends, the pantograph base moves a distance sufficient for the pad 307 to contact the bottom of the pantograph and press it, and the extrusion force of the pad 307 on the front and back is sufficient to support it to contact the detection cable 6 in the detection cover 4 and be subject to friction.
[0025] Two annular grooves 311 are provided on the outer walls at both ends of each support shaft 305, and the outer wall at one end of each connecting rod 306 is slidably connected to the inner wall of each annular groove 311. An anti-slip pad 312 is fixedly provided on one side of each clamping plate 307. The anti-slip pad 312 on one side of the clamping plate 307 mainly increases the friction between the clamping plate 307 and the pantograph, and improves its stability after installation.
[0026] Furthermore, a detection cover 4 is installed at the middle position of the top of the detection base 1. Mounting brackets 5 are installed at both ends of the upper side of the inner wall of the detection cover 4. Multiple detection cables 6 are connected at equal distances between the two mounting brackets 5. Before detection, the extension height of the pantograph arm can be adjusted so that the top of the pantograph arm can contact the detection cables 6 sufficiently.
[0027] Two mounting brackets 5 are each fitted with a fixed bracket 7 at both ends of their tops. Each of the four fixed brackets 7 has a second spring 8 fitted on the outer wall of one end. One end of each second spring 8 is fixedly connected to the two ends of the tops of the two mounting brackets 5. During the moving detection, the pantograph arm at the top of the pantograph always squeezes the detection cable 6 and squeezes the mounting brackets 5 at both ends when entering and leaving the detection cover 4. The second spring 8 allows the connection between the mounting bracket 5 and the fixed bracket 7 to be extended and retracted, providing a certain buffer. During the squeezing, the mounting bracket 5 can retract to prevent excessive force from damaging the pantograph.
[0028] Working Principle: When using the mobile pantograph detection equipment in this design, the pantograph is equipped with a base structure for connection to the top of a vehicle. The pantograph is mounted on the upper end of the support base 301 via the base, causing the compression pad 310 to descend, pulling the compression shaft 308 down and stretching the first spring 309. Simultaneously, the support shaft 305 slides down in the mounting groove 304. As it slides down, the connecting rod 306 rotates in the annular groove 311 on its surface, passing through the inner wall of the connecting groove 303 and pulling the clamping plates 307 in the upper limiting groove 302 closer together. Finally, the two sides of the pantograph base placed on the support base 301 are pressed and fixed. Then, the conveyor 2 is started to transport the pantograph fixed by the mounting mechanism 3 into the mounting system. Inside the detection cover 4, the pantograph is brought into contact with the detection cable 6 connected to the top of the detection cover 4 via the mounting bracket 5, and current is applied to energize the pantograph. The data displayed on the control panel is used to check whether the pantograph's power receiving performance is up to standard. When installing the pantograph via the mounting mechanism 3, it is only necessary to place the pantograph on the support base 301 to fix it in place, ensuring that its position does not shift during movement and detection. This also allows for faster detection speed. After the detection is completed, the pantograph is lifted upwards, and under the elastic action of the first spring 309, the support shaft 305 slides upwards, which in turn pushes the clamp 307 outwards via the connecting rod 306 to release the clamping and fixing of the pantograph base. This reduces the workload of the staff and improves the detection efficiency of the device.
