Description

Technical Field

[0001] This utility model relates to the technical field of tension compensation monitoring equipment, specifically to a monitoring terminal for a contact wire tension compensation device. Background Technology

[0002] The catenary compensation device is a general term for compensators and braking devices used to automatically adjust the tension of the contact wire and catenary cable. When the temperature changes, the wire will expand or contract due to thermal expansion and contraction. Compensators are installed at the anchor points of the wire at both ends of the anchor section. Under the action of the weight of the weights, the tension of the wire can be automatically adjusted and the wire sag can be kept in accordance with the technical requirements. This improves the stability and elasticity of the contact suspension and enhances the operation quality of the catenary.

[0003] The overhead contact line compensation device in the tunnel needs to be monitored through periodic dynamic waveform analysis, onboard inspection, 2C patrol, and foot patrol to ensure that the device functions properly. However, due to factors such as the inspection cycle and data acquisition time, there is currently a lack of means to detect potential equipment problems in advance, and it is impossible to keep track of changes in the compensation device in special sections in real time. Manual inspection is inefficient, time-consuming, and labor-intensive. In view of this, we propose a monitoring terminal for the overhead contact line tension compensation device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned in the background art and provide a monitoring terminal for the contact wire tension compensation device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The overhead contact line tension compensation device monitoring terminal includes a main support frame, and also includes:

[0007] The detection assembly includes a detection body mounted in the middle of the main support via a mounting clamp, and a protective wire clamp assembly mounted on the outside of the detection body;

[0008] Laser rangefinders are symmetrically installed at both ends of the main support.

[0009] Two slide rails are vertically installed at both ends of the main support. A support frame is connected between the two slide rails, and a support plate is slidably installed on the slide rail. A weight is installed on the top of the support plate, and a detection sticker corresponding to the position of the laser rangefinder is installed on the bottom surface of the weight.

[0010] Preferably, a wiring board is installed on the detection body, and a detection window is installed on the top surface of the detection body. The two ends of the mounting clamp are detachably mounted on the main bracket by screws.

[0011] Preferably, the protective clamping assembly includes rubber posts installed on the top and outer sides of the mounting clamp, and a protective cover plate fitted over the outside of the testing machine body;

[0012] The protective cover plate is provided with snap-fit ​​holes corresponding to the positions of the rubber columns.

[0013] Preferably, a flip plate is hinged to the protective cover near the wiring board, an upper rubber rod is glued to the bottom end of the flip plate, and conduits are installed at both ends of the flip plate through extrusion screws.

[0014] Preferably, a sliding rod is slidably installed inside the conduit, and a lower rubber rod is connected between the bottom ends of the two sliding rods respectively;

[0015] The upper and lower rubber rods are parallel to each other, and the outer sides of the upper and lower rubber rods are rough surfaces.

[0016] Preferably, the protective cover is inverted L-shaped.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The monitoring terminal of the contact wire tension compensation device is equipped with a detection component, which can detect the distance between the laser rangefinder and the detection sticker, thereby monitoring and predicting the status of the weight. It can replace manual inspection and perform real-time monitoring of the operation of the compensation device to ensure the normal operation of the contact wire compensation device.

[0019] 2. Equipped with protective clamping components and protective structures, it can shield against flying stones and other debris. When wiring is required, loosen the squeezing screw, rotate the flip plate, and when the wiring is completed, push the lower rubber rod to rise. The slide rod slides inside the guide until the upper and lower rubber rods squeeze and fix the connecting wire. Then rotate the squeezing screw to fix the slide rod. This can prevent the connection from loosening due to vibration when the train is moving forward, which would affect the detection accuracy and ensure reliable monitoring.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0030] The contact wire tension compensation device monitoring terminal includes a main support 1. Two detection components 2 are symmetrically installed on the outside of the main support 1. The detection components 2 include a detection body 201 installed in the middle of the main support 1. In this embodiment, a wiring board 202 is installed at one end of the detection body 201, and a detection window 203 is provided on the top surface of the detection body 201. Laser rangefinders 204 are installed at both ends of the main support 1.

[0031] It is important to note that, for example Figure 4 As shown in the structure, a mounting clamp 205 is detachably installed on the outside of the testing body 201. The mounting clamp 205 is attached to the outside of the testing body 201 for limiting, and a protective wire clamping assembly 206 is installed on the outside of the mounting clamp 205.

[0032] Specifically, slide rails 207 are installed on both sides of the main support 1, support frames 208 are installed on the slide rails 207, and support plates 209 are slidably installed inside the slide rails 207. A weight 210 is installed on the top of the support plate 209. A detection sticker 211 is attached to the bottom of the weight 210 corresponding to the laser rangefinder 204. The laser rangefinder 204 is located directly below the detection sticker 211. A pad plate 212 is attached to the bottom of the laser rangefinder 204. The laser rangefinder 204 is connected to a power source through a controller to ensure that the laser rangefinder 204 is in a horizontal state and to ensure detection accuracy.

[0033] The protective clamping assembly 206 includes rubber posts 2061 that are bonded to the top and outside of the mounting clamping plate 205. An inverted L-shaped protective cover plate 2062 is sleeved on the outside of the detection body 201. The rubber posts 2061 and the snap-fit ​​holes 2063 are connected by an interference fit to facilitate the blocking of splashed stones and other debris.

[0034] like Figure 4 The structure shown has a hinged rotating plate 2064 mounted on the outer end of the protective cover 2062. An upper rubber rod 2065 is bonded to the bottom end of the rotating plate 2064. Both ends of the rotating plate 2064 are welded with conduits 2066. A compression screw 2067 is installed at the bottom end of the conduit 2066 through a screw hole. A slide rod 2068 is slidably mounted inside the conduit 2066. The bottom ends of the two slide rods 2068 are respectively connected to the two ends of the lower rubber rod 2069. The upper rubber rod 2065 and the lower rubber rod 2069 are parallel to each other, and the outer surfaces of the upper rubber rod 2065 and the lower rubber rod 2069 are rough surfaces to facilitate the clamping of the data connection cable by the upper rubber rod 2065 and the lower rubber rod 2069.

[0035] In this embodiment, the detection body 201 is made of aluminum alloy and anodized. It is IP68 sealed, which is corrosion-proof, waterproof, and bubble-proof. It contains industrial desiccant to prevent internal moisture and condensation. It is equipped with a temperature acquisition device, a humidity acquisition device, a LoRa data transmission device, a 1000mA lithium-ion battery, a main control motherboard, and a CT power supply board. It mainly realizes the measurement of the contact network AB value, temperature and humidity acquisition, data transmission, and CT power supply. This part belongs to the prior art, so it will not be explained in detail.

[0036] The laser rangefinder 204 is used to accurately measure the distance of the falling weight 210 from the ground. In this embodiment, the monitoring terminal is equipped with temperature and humidity environmental monitoring sensors. Combined with laser rangefinder, it realizes intelligent monitoring result analysis and falling weight 210 status prediction. This embodiment can transmit data based on the existing long-distance, low-power LoRa+NB-IoT Internet of Things technology. In open environments, it can achieve data transmission between terminals up to 10km, and in tunnels, it can achieve data transmission up to 2km. The communication distance can be extended through repeaters. The terminal is equipped with a large-capacity, high-reliability battery and also supports external power supply access for CT sensing, which can support long-term use in tunnels.

[0037] The working principle and usage process of this utility model are as follows: A support plate 209 is installed at the bottom of the weight 210, and the support plate 209 is slidably installed in the slide rail 207. The slide rail 207 is connected to the tunnel wall through the support frame 208. Then, a main support 1 is installed on the ground between the two slide rails 207. The detection body 201 of the detection terminal is installed in the main support 1. Laser rangefinders 204 are installed at both ends of the main support 1. A pad plate 212 is installed at the bottom of the laser rangefinder 204 to ensure that the laser rangefinder 204 is in a horizontal state. A detection sticker 211 is attached to the ground of the weight 210 directly above the laser rangefinder 204 to facilitate subsequent detection. The connection board 202 is connected to the required data cable. The main support 1 is located near the top of the cable trench cover, and the connected data cable can be laid in the cable trench as needed. As the contact wire tightens and relaxes, it drives the weight 210 to move up and down. When inspection is required, the laser rangefinder 204 detects the distance between the laser rangefinder 204 and the detection sticker 211. The monitoring results are used to analyze the status of the weight 210. The tunnel contact wire compensation device monitoring platform can replace manual inspection and monitor the operation of the compensation device in real time, realizing dynamic monitoring of the contact wire compensation device and the railway line perimeter environment. At the same time, the dynamic monitoring data is reported in real time using LoRa long-distance data communication technology to ensure the normal operation of the contact wire compensation device.

[0038] The outer side of the testing machine body 201 is equipped with a protective structure. The rubber column 2061 is aligned with the snap-fit ​​hole 2063 and snaps into the protective cover plate 2062 to block flying stones and other debris. When wiring is required, the squeezing screw 2067 is loosened and the flip plate 2064 is rotated. When the wiring is completed, the lower rubber rod 2069 is pushed up and the slide rod 2068 slides in the guide tube 2066 until the upper rubber rod 2065 and the lower rubber rod 2069 squeeze and fix the connecting wire. Then the squeezing screw 2067 is rotated to fix the slide rod 2068 to prevent the vibration of the train from causing the connection to loosen and affecting the testing accuracy, thus ensuring the smooth progress of the testing.

[0039] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0040] Furthermore, if the embodiments of this utility model involve descriptions such as "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
