[0027] To make the purpose, technical solution and advantages of the present utility model clearer, the technical solution of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.
[0028] As described in the background art, the measurement method in the prior art is that the line inspection personnel stand under the line to be detected, hold up the insulating rod with their hands to contact the lowest point of the line, and then determine whether the distance between the lowest point of the line and the highest point of the ground and the building is a safe distance through the length of the insulating rod and the height of the lower end of the insulating rod from the ground.
[0029] Based on this, the present utility model provides a wire height measuring instrument. The equipment main body of this measuring instrument moves on the contact wire through the auxiliary moving mechanism. During the process of the auxiliary moving mechanism carrying the equipment main body to move, the measuring mechanism measures the distance between the contact wire and the base surface, and displays it through the display screen, obtaining the height of the contact wire from the base surface, improving the measurement accuracy and measurement efficiency, and at the same time reducing the labor cost.
[0030] The following combines specific attach Figures 1-5 A preferred implementation mode of the wire height measuring instrument of the present utility model will be described in detail.
[0031] As Figures 1-5 shown, it is a schematic structural diagram of the wire height measuring instrument of the present utility model. This kind of wire height measuring instrument includes an equipment main body 1, and the equipment main body 1 is provided with an auxiliary moving mechanism 2 and a measuring mechanism. The auxiliary moving mechanism 2 is used to drive the equipment main body 1 to move on the contact wire, and the measuring mechanism is used to measure the distance between the contact wire and the base surface during the movement of the equipment main body 1.
[0032] As Figures 1-3As shown in the figure, the auxiliary moving mechanism 2 of this embodiment is located above the equipment main body 1 and is fixedly connected to the equipment main body 1. The measuring mechanism is located below the equipment main body 1 and is also fixedly connected to the equipment main body 1. Among them, the auxiliary moving mechanism 2 is preferably a laser rangefinder 3. The laser rangefinder 3 is fixedly installed on the lower surface of the equipment main body 1. The laser rangefinder 3 emits laser to measure the distance between the contact wire and the base surface, that is, to measure the height of the wire.
[0033] The auxiliary moving structure includes a frame body 21 and auxiliary wheels 22. As Figure 1 shown, the frame body 21 is arranged above the equipment main body 1 and is fixedly connected to the equipment main body 1. The auxiliary wheels 22 are arranged in pairs at both ends of the frame body 21. In this embodiment, the cross-section of the auxiliary wheels 22 is preferably V-shaped. The V-shaped auxiliary wheels 22 can hold the contact wire to prevent the auxiliary wheels 22 from falling off the contact wire.
[0034] In addition, the equipment main body 1 of this embodiment also has a data conversion module and a data collection module.
[0035] The data conversion module is electrically connected to the laser rangefinder 3 and the display screen 11 at the same time. The data conversion module is used to convert the data of the laser rangefinder 3 into the data displayed on the display screen 11 and display it through the display screen 11. That is, the laser rangefinder 3 emits laser to measure the distance between the contact wire and the base surface, and then transmits the obtained data to the data conversion module. The data conversion module converts it and displays it on the display screen 11.
[0036] The data collection module is also electrically connected to the laser rangefinder 3. The equipment main body 1 also has a TF card socket 12 for inserting a TF card. The TF card socket 12 is electrically connected to the data collection module.
[0037] The data collection module collects the distance between the contact wire and the base surface measured by the laser rangefinder 3, and then transmits the measured data to the TF card installed on the TF card socket 12. The TF card is used to save the measured data. After the TF card is pulled out, it can also be inserted into other PC terminals, so that the data can be further saved or analyzed.
[0038] As Figures 1-3 shown, an encoder ranging wheel 4 is provided on the other side of the frame body 21 opposite to the auxiliary wheels 22. The encoder ranging wheel 4 is used to measure the moving distance of the equipment main body 1 on the contact wire.
[0039] In addition, as Figure 2 shown, a charging port 14 and a switch 13 are provided on one side of the equipment main body 1.
[0040] The specific measurement process is as follows:
[0041] The auxiliary wheel 22 is in direct contact with the contact wire of the railway catenary. The switch 13 is turned on, and the display screen 11 and the laser rangefinder 3 are activated. By moving along the contact wire, the laser rangefinder 3 measures different height information, which is synchronously displayed on the display screen 11 and synchronously recorded on the TF card, facilitating data recording and synchronization for subsequent viewing of the measurement data.
