Description

Technical Field

[0001] The invention relates to the field of portable detection tools, in particular to a contact network line branch detection device. Background Art

[0002] The current contact network flexible line switch device is as follows Figure 1 As shown, it includes the side line contact line and the main line contact line that meet above the intersection of two railways, and the intersection of the side line contact line and the main line contact line is connected and fixed by a limiting tube. The positioning point (line spacing is 200mm~400mm) refers to the contact line positioning device of the main line contact line and the side line contact line near the line branch position, which is used to fix the horizontal distance and vertical height of the two contact lines. The intersection point (line spacing is 500mm~600mm) refers to the projection point from the intersection of the main line contact line and the side line contact line to the rail plane. Figure 1 The center line of the main line refers to the center line of the two rails of the main line; Figure 1 The siding centerline refers to the centerline of the two siding rails.

[0003] When one set of contact wires is lifted by the pantograph, the other set of contact wires can also be lifted at the same time, so that it has a height difference with the other contact wire. The height difference decreases as the pantograph approaches the starting contact point. When it reaches the starting contact point, the height difference is basically eliminated, so that the pantograph can be smoothly handed over, and no bow scraping phenomenon occurs. At present, the detection method for the contact network flexible line switch device is to manually measure at 500mm of the line switch opening with a level ruler to ensure that the conductor height at this point meets the technical standards. This detection method has the following problems:

[0004] 1) This measurement method belongs to static measurement, and the height of the contact network is in a static state. However, when the train is actually running, the pantograph will exert a lifting force of about 120N on the contact network, and the contact line will move up 3cm-5cm. Therefore, traditional manual detection methods cannot grasp the actual working conditions of the contact network when the train is dynamic.

[0005] 2) The side wear phenomenon at the switch has always been a difficult problem in the maintenance of the contact network switch. In daily maintenance, we can only rely on experience to determine the location and cause of the side wear, and adjust the contact wire height and pull-out value at the contact network flexible switch device. After the adjustment is completed, there is no basis to prove that the side wear of the switch has been solved, and it can only be solved through subsequent review. Summary of the invention

The measurement starting point 0 of the first measuring ruler assembly 41 is located at the center of the pantograph 5, and the measurement range of the length scale value is 0mm to 830mm. The measurement starting point 0 of the second measuring ruler assembly 42 is located at the center of the pantograph 5, and the measurement range of the length scale value is 0mm to -830mm (it can be understood that the - sign here only indicates the measurement reading direction). The first measuring ruler assembly 41 and the second measuring ruler assembly 42 arranged on the upper part of the device in this embodiment have the same function and working principle, and their main function is to facilitate users to measure the horizontal pull-out value of the contact line 7 at multiple positions.

[0062] The pantograph 5 includes: a carbon slide plate 501, a base 502, a first support seat 503 and a second support seat 504; the first support seat 503 and the second support seat 504 are respectively arranged on the top surfaces at both ends of the second top plate 313; the two ends of the base 502 are respectively arranged on the first support seat 503 and the second support seat 504; the carbon slide plate 501 is arranged on the base 502; the contact line 7 slides freely along the upper surface of the carbon slide plate 501.

[0063] Please continue to refer to Figure 8 , fix the contact network branch detection device provided in this embodiment on the vehicle ladder, keep the center of the contact network branch detection device and the center of the carbon slide 501 consistent with the center position of the vehicle ladder, and lock the fastening claw. Turn the hand wheel clockwise to lift the device (the carbon slide 501 rises from the height position of B1 to the height position of B2, and the height represented by B2 is greater than the height represented by B1), and observe the pressure value on the bow-net contact force scale display module (the bow-net contact pressure value observed in the first observation component 32 and / or the second observation component 33), and stop the operation when the bow-net contact pressure value (the sum of the downward pressure F1 and the lifting force F2) reaches 120N. At this time, the contact network branch detection device has the detection function, and the car ladder is pushed to the contact network branch for detection. The detection content is: at the inlet and outlet of the branch, observe the state of the bow and net, whether there is side wear and horn over-limit (whether the pantograph horn and the contact line are worn laterally, whether the wear position is within the specified limit of the horn, and the standard limit carbon slide plate and the horn are connected to the horn at a horizontal distance of 230mm from the horn. The position is projected vertically to the horn as the standard limit). If side wear is found, the contact network branch detection device is used to measure the horizontal pull-out value of the contact line 7 at this location, and the contact line 7 is painted with a red mark for easy review and adjustment. When the contact network branch detection device passes through the entire branch to be detected, observe the state of the contact network equipment in a dynamic state. The state of the contact network equipment includes whether the positioning point, the branch body, and various types of wire clamps have tilt limits. After the trial is completed, record the relevant data, defects, etc. of the branch, and formulate corresponding adjustment plans.

[0064] The contact network switch detection device provided in this embodiment is a portable detection tool. When in use, it can be installed on a car ladder to simulate the dynamic characteristics of other pantographs on the train, and achieve the effect of dynamically detecting the contact network switch. By using the detection device on the car ladder, it can be found whether the pantograph has horn intrusion, switch side wear, etc. when passing through the switch, and the contact network switch can be adjusted on site according to the detection results. After the adjustment, the detection device can be used to further verify whether the contact network switch is adjusted in place, thereby improving the safety factor of the contact network equipment.
