Description
Technical Field
The invention relates to the technical field of vehicle-mounted contact network operation state detection, in particular to a geometric parameter simulation device for a contact network, which can accurately simulate geometric parameters of a contact line and has operability and strong practicability.
Background
The space position of the contact line in the contact net must be in the working range of the locomotive pantograph, so that the carbon slide plate of the locomotive pantograph constantly keeps contact with the contact line, and the contact line can well provide electric energy for the locomotive. Therefore, the geometric parameters of the contact network are one of the important indexes for evaluating the state of the contact network, and the working state of the contact network directly influences the driving safety.
At present, the detection of the geometric parameters of the contact network in China is mostly detected by inspection by a detection vehicle or manual climbing on an insulating ladder. Manual detection is in most cases only taken when there is a problem with the bow net system. The inspection vehicle is limited by the inspection route and the inspection length, and real-time monitoring on the pantograph-catenary system cannot be realized, so that the application range of the inspection vehicle is small. With the continuous development of electric locomotives, in order to realize the real-time monitoring of a pantograph-catenary system, the development of a vehicle-mounted catenary operation state detection device is constantly applied to China in recent years. The vehicle-mounted contact net operation state monitoring device has two types of contact detection and non-contact detection. The contact detection device is installed on a pantograph, so that certain potential safety hazards exist, the precision is not high, and the contact detection device is basically eliminated at present. The non-contact measurement is to measure the geometric parameters of the contact net by means of laser scanning, image recognition or ultrasonic waves, and the like, and has the advantages of high precision, strong anti-interference capability and the like, which are mainly adopted at present.
Along with the continuous popularization and application of the non-contact vehicle-mounted contact network operation state detection device, the accuracy requirement on the detection device is further improved, and a device for correspondingly detecting the accuracy of the vehicle-mounted contact network operation state detection device also appears. The existing devices for testing the accuracy of the vehicle-mounted detection device (hereinafter referred to as "catenary geometric parameter simulation devices") in the current market are mostly designed according to the real structure of the catenary. The device can establish a movable real contact net section, including contact wires, suspension, carrier cables and the like. The pantograph also adopts a real pantograph device, and the lifting of the pantograph can be simulated really. The device can highly restore the contact state of the bow net system.
The existing catenary geometric parameter simulation devices have various forms, wherein one form is that a vehicle-mounted catenary operation state detection device (a 3C device for short) is installed on a real locomotive, the locomotive runs along a track, and the height and the angle of contact lines at specified positions on two sides of the track are known determined values. And comparing the contact line geometric parameters of the specified position detected by the 3C device in the driving process with the known determined values, thereby obtaining the detection accuracy of the 3C device. Although the form is strong in authenticity, the static geometric parameters and the dynamic geometric parameters of the contact network are greatly different, and the contact network cannot be generally adopted due to the limitation of cost, field and the like.
Another relatively simple device has emerged to address the shortcomings of the above forms. The device does not need to utilize a contact net and a real locomotive, but adopts a simplified form. The real contact net is simplified into a relatively short movable contact net, so that the height and the horizontal position of the contact line can be adjusted. The real locomotive is simplified into a lifting mechanism only keeping a pantograph. Since the contact wire can move relative to the pantograph, the position of the pantograph can be kept fixed. The device of this form can place in the spacious room that the area is great because the size is less relatively, but in order to guarantee that the contact line can flare-out, the stand size and the weight of both ends fixed contact line are all great, are not convenient for manually move. Although the device has strong authenticity, the device needs to be matched by a plurality of people during operation due to the influence of size and weight. It cannot be used generally due to the disadvantages of poor operability and inconvenience of being placed indoors in a small space.
