Description

Technical Field

[0001] The utility model belongs to the field of wheel-rail monitoring supporting equipment, and particularly relates to a wheel sensor installation device. Background Art

[0002] When the railway department detects passing vehicles on the line, it is necessary to install wheel sensors. Its main functions include real-time detection of the passing of wheels, realizing the axle counting function, judging the driving direction of the train, and judging the approximate position of the train by recording the number of wheel axles in the subway train, playing a positioning role. It can also be used as a switching signal for starting equipment in combination with other equipment. The existing sensor installation method mainly installs and positions through installation and fixing structures such as bolt buckles. However, due to the wheel-rail vibration caused by the high-speed movement of the vehicle, the existing installation and positioning structure will quickly loosen and shift, resulting in the deviation of the sensing signal, and ultimately causing misjudgment of the equipment using this signal, affecting the use of the detection equipment and the driving safety.

[0030] The following describes the specific structure of the foregoing core structure in detail with reference to the accompanying drawings.

[0031] As Figure 1 , Figure 3 , Figure 4 , Figure 5 shown, the adjusting bracket is mainly used to form a basic connection structure, and while serving as a sensor support structure, it provides a support basis for other clamping and fixing structures.

[0032] The adjustment bracket 1 includes a connecting plate 10 and a number of adjusting plates 11 located at the bottom of the connecting plate 10; a number of locking screw holes 10b are dug downward on the connecting plate 10; a strip-shaped adjustment hole 11a is dug backward on the adjusting plate 11, and the strip-shaped adjustment hole 11a extends vertically.

[0033] For ease of processing and manufacturing, and at the same time to simplify the difficulty of assembly and use, in this embodiment, the connecting plate 10 adopts a strip-shaped plate structure, and the strip-shaped plate structure is adapted to various necessary supporting structures such as sensor installation boxes / installation brackets, etc. The top of the connecting plate 10 is set as a horizontal installation surface 10a for easy corresponding connection. Among them, the locking screw holes 10b are arranged on the horizontal installation surface 10a and there are at least two and are close to both ends of the connecting plate 10 to meet the basic assembly and fixing requirements. In actual use, according to the needs of the sensor installation structure, the size structure of the installation plate and the installation surface, as well as the number and position of the required locking screw holes, can be flexibly configured.

[0034] Among them, the connecting bolt 4 is inserted into the strip-shaped adjustment hole 11a from front to back; the locking bolt 5 is installed from bottom to top in the locking screw hole 10b, and the locking nut is installed on the part of the locking bolt 5 that extends out of the locking screw hole 10b; through holes 9c for sleeving on the connecting bolt 4 are respectively provided on the first rail block 2 and the second rail block 3; a wheel-rail positioning card slot 9a is dug on the relative side of the first rail block 2 and the second rail block 3; the locking nut 6 is installed at the end of the connecting bolt 4 and presses against the first rail block 2.
