Description

Technical Field

[0001] The utility model relates to an auxiliary tool for a contact network parameter detection device, belonging to the technical field of a contact network hanging string point detection device for an electrified railway. Background Art

[0002] In order to ensure the safe and efficient operation of the railway contact network, Article 60 of the "High-speed Railway Contact Network Operation and Maintenance Rules" (No. 362, China Railway General Transportation

[2015] ) stipulates that the static inspection cycle of contact geometric parameters (contact wire pull-out value, mid-span offset value, contact wire height, contact wire slope) is 12 months. Article 85 of the "Conventional Railway Contact Network Operation and Maintenance Rules" (No. 9, China Railway General Transportation

[2017] ) stipulates that the service life of the overall suspension string is 10-12 years. It can be seen that contact network parameter measurement is a very important task in daily operation, and data accuracy is the key to ensuring the smooth and efficient operation of trains. At present, the Qingrong Intercity Railway was opened in 2014, and due to environmental factors such as strong winds along the coast, the suspension strings are approaching the end of their service life and have been included in the replacement plan. Before replacement, it is necessary to use a contact network parameter detection device to measure the contact network geometric parameters. The existing contact network parameter detection devices have the following main disadvantages when used:

[0003] 1. When the contact network parameter detection device is used in the high-speed railway maintenance skylight (railway skylight refers to the time reserved for construction and maintenance operations when the train running line is not laid or the train running is adjusted or reduced during the train running. It is divided into construction skylight and maintenance skylight according to its use. See Document No. 280 of Railway Transport

[2012] . In order to ensure driving safety, high-speed railway operation Figure 1 Generally, a 5-6-hour comprehensive maintenance skylight is set up at night to carry out comprehensive maintenance of the line, communication signal and power supply equipment. ), Due to the dim light on the railway line at night, the recognition rate of the hanging string is low. A large number of hanging string points can only be added later through analysis software, but the accuracy of the data cannot be guaranteed. According to the "High-speed Railway Contact Network Safety Work Rules" (No. 221 of the Railway General Transport

[2014] ), the identification of hanging strings requires the cooperation of two personnel, one operator and one guardian. Among them, the operator is responsible for driving the contact network parameter detection device for detection. The guardian needs to monitor the operator uninterruptedly and cannot participate in direct operations. That is, the guardian cannot hold a light source to illuminate the hanging string. Even if the guardian violates the rules and operates the handheld light source to illuminate the upper hanging string, it cannot be guaranteed that the light source position of the handheld light source remains unchanged relative to the hanging string, which affects the recognition rate. If the operator uses a head-mounted light source to illuminate the hanging string, the height of the head-mounted light source is greater than or equal to the height of the laser radar of the contact network parameter detection device, resulting in horizontal light irradiating the radar surface, which will affect the recognition rate of the hanging string.

[0004] 2. During the inspection process, the operating personnel need to wear a recorder to record the entire inspection process. Since the staff will inevitably shake and rotate when walking, the recorder image will be unclear or damaged, affecting the subsequent image review.

[0005] 3. During nighttime operations, the guardian needs to wear protective lighting fixtures to illuminate the road ahead and release warning signals. However, since protective lighting fixtures are easily blocked by body clothing, etc., the warning to adjacent or opposite directions is low during the operation, posing a safety hazard to the operation.

[0006] 4. When operating personnel operate the contact network parameter detection device to inspect the string points at night, they need to record the inspection process at any time. The existing contact network detection equipment is not equipped with a recording mechanism, which makes recording inconvenient, and it is very troublesome to record faults in insufficient light.

[0007] Therefore, there is an urgent need for a detection auxiliary tool that can solve the above-mentioned technical problems. Utility Model Content
