Abstract
Description

[0002] In the construction of electrified railway and rail transit projects, the simple catenary suspension in the electrified railway is the most common installation method. Before the contact wire is fixed at the position of the catenary support point, the offset value of the boom needs to be determined jointly according to the material of the catenary wire, the wire temperature during installation and adjustment, the compensation tension and the anchor section length, and then the contact wire is fixed. Among them, the wire material and compensation tension are both fixed values, and the anchor section length and temperature are variables for calculating the boom offset value. In the construction of the catenary, at the support of each hanging boom, the calculation of the boom offset value is involved. Only by controlling the boom offset value and offset size confirmation under different conditions can the accuracy of the boom installation offset and the construction quality be ensured. The traditional boom offset is calculated through an Excel table. On-site, underground laser positioning, a thermometer is used to measure the wire temperature, and a tape measure is used to measure the offset. The operation is relatively cumbersome, and the result is likely to be inaccurate. Content of the Utility Model

[0026] Such as Figure 1-6A catenary temperature-sensing offset measuring ruler as shown includes a temperature-sensing hook 1 for hanging on the catenary carrier cable, a fixed frame 2 arranged below the temperature-sensing hook 1, and a scale 3. A measuring assembly 4 is rotatably connected inside the fixed frame 2. The measuring assembly 4 includes a measuring frame 401 rotatably connected to the fixed frame 2. A measuring host 402 and a display screen 403 are installed on the measuring frame 401. A laser emitting device 5 is arranged on the back of the measuring frame 401.
[0027] The temperature-sensing hook 1 includes a hook body 101 and a temperature sensor 102. The temperature sensor 102 is connected to the input end of the measuring host 402, and the display screen 403 is connected to the output end of the measuring host 402. The hook body 101 is a stainless-steel hook.
[0028] The temperature sensor 102 is fixed inside the arc-shaped groove on the inner side of the hook body 101 by inlaying to form an integral structure. The inner side of the hook contacts the object to be measured to measure the temperature of the object to be measured in real time. The temperature sensor 102 is connected to the measuring host 402 through a temperature-sensing wire. The measuring host 401 is a single-chip microcomputer for receiving detection signals and calculating.
[0029] A power supply 6 is also arranged on the back of the measuring frame 401 to supply power to each electrical component. The measuring host 402 and the laser emitting device 5 are electrically connected to the power supply 6.
[0030] A rotating shaft 7 is arranged in the middle of the fixed frame 2. The measuring frame 401 is installed on the rotating shaft 7. A power-on key is arranged on the measuring frame 401. The scale 3 is installed at the bottom of the fixed frame 2.
[0031] The scale 3 is a retractable measuring ruler. The zero scale line of the scale 3 is on the same line as the center of the temperature-sensing hook 1.
[0032] When the utility model is specifically used, the temperature-sensing hook 1 is hung on the catenary carrier cable to make the temperature sensor 102 contact the carrier cable, and the real-time temperature of the carrier cable is detected. The actual temperature of the wire can be fed back to the measuring host 402 through the temperature-sensing sensor 102 in real time. The laser emitting device 5 is turned on and aimed at the catenary support behind to emit laser. The hook can be moved or the measuring frame can be rotated up and down to adjust the laser emission position so that the emitted laser is directly aimed at the center of the catenary support. The center line is found at the measured point through the laser beam. It is directly operated by the measuring personnel, which is convenient and simple, and the result is easier to control. After the centering is completed, the length from the measured positioning point to the center anchor (or hard anchor) is input through the touch screen. The single-chip microcomputer processes and calculates to obtain the offset value of the wrist arm at the current temperature. The display screen 403 displays the measurement result. According to the calculation result of the measuring host 402, the corresponding offset value is found on the scale 3 and marked on the wire to complete the measurement and positioning of the wrist arm offset.
