Description

Technical Field

[0001] The utility model relates to the technical field of measurement devices, in particular to a device for suspension measurement of rigid contact network of subways. Background Art

[0002] There are four main installation forms of subway rigid contact network suspension, namely horseshoe-shaped tunnel suspension installation, station duct suspension installation, hanging column installation and circular tunnel suspension installation. The main functions of rigid contact network suspension are two: one is to fix the busbar, and then fix the contact line to support the power supply of subway trains; the other is to adjust the pull-out value of each suspension point to the required value, showing a zigzag change, to ensure the service life of the contact line.

[0003] The pull-out value generally changes in a zigzag shape between -250 and 250. Based on this characteristic, when positioning the rigid contact network suspension base, the positioning points with a pull-out value less than 150 (absolute value less than 150, i.e. between -150 and 150) are generally aligned with the positioning of the suspension points with a pull-out value of 0, and the pull-out value is adjusted to the required value using the long hole angle steel on the suspension; and the positioning points with a pull-out value greater than 150 (absolute value greater than 150) are aligned with the positioning of the suspension points with a pull-out value of 150, and the pull-out value is also adjusted to the required value using the long hole angle steel on the suspension (due to the particularity of the anchor section joint, all positioning is performed according to the pull-out value of 0). According to this positioning method, the overall appearance of the suspension point after installation is relatively smooth and beautiful, and the overhead ground wire installed on the suspension base will also be relatively smooth without corners. At present, most subways in the country are suspended and positioned in this way.

[0004] When measuring the rigid contact network suspension points of the subway, the DJJ-8 laser rangefinder is used for detection, and the height and pull-out value measurement functions of the DJJ-8 are used to measure the rigid contact network suspension points of the subway. However, the DJJ-8 is expensive, with a price of about 20,000 yuan per unit, which increases the cost. In addition, the DJJ-8 is large in size and weight, making it inconvenient to carry. Therefore, we provide a device for measuring the rigid contact network suspension of the subway. Utility Model Content

[0005] The technical problem solved by the utility model is that the existing rigid contact network suspension point positioning and measuring equipment for subways has the problems of high cost, large weight and inconvenience in carrying.
