The centering plate 4 plays a role in drawing the hinge rod 3, and is matched with the synchronous guide rod 7, so that the centering plate 4 is always positioned on the fan-shaped central line formed after the hinge rod 3 is opened and closed. After the side clamping plates 2 are clamped tightly, the line drawing ports 6 can be matched with stone pens to determine central points on the rail surface 1 of the rail and mark the central points, the two ends of the centering plate 4 are respectively provided with one line drawing port 6, according to the principle that one line is determined by two points, the central line of the rail surface 1 of the rail can be determined through the two central points, and finally rail centering operation is finished.
Specifically, the middle of the fixed middle plate 4 is provided with an inspection hole 10, the inspection hole 10 is a through hole, two v-shaped grooves are oppositely arranged on the inner side wall of the through hole, the symmetrical lines of the two v-shaped grooves are superposed with the symmetrical line of the fixed middle plate, and whether the marked track central line is accurate can be checked through the two v-shaped grooves. That is, the inspection hole 10 has a date pit type structure.
In another preferred implementation manner based on the foregoing embodiment, there is provided a method for track measurement centering in the present implementation manner, where the method for track measurement centering in the present implementation manner is implemented by using the apparatus for track measurement centering in the foregoing implementation manner, and the method includes the following steps:
step one, S101: mounting the rail measurement centering device on the rail upper rail surface;
step two S102: observing scales on the synchronous guide rod, and acquiring width data of the rail surface on the rail;
step three, S103: marking points are respectively arranged at the positions where the central positions of the line drawing ports at the two ends of the centering plate are contacted with the rail surface on the track;
step four S104: and removing the device for track measurement centering, and connecting the two mark points.
Specifically, when the device for track measurement centering is installed, the device for track measurement centering is placed on the track upper rail surface, the centering plate is pulled to drive the two side clamping plates to synchronously move so as to clamp the track, and the clamping grooves in the centering plate are in close contact with the track upper rail surface.
Specifically, the method for centering orbit measurement is implemented as follows: opening a device for centering track measurement and placing the device on a track; slowly drawing the fixed middle plate to enable the side clamping plates of the device for measuring and centering the track to slowly clamp the track, wherein in the clamping process, the clamping plates on the two sides are required to be ensured to completely cover the track, and a gap is prevented from being formed between a clamping groove of the side clamping plate and the track; fixing a synchronous guide rod ruler with one side clamping plate, enabling a synchronous guide rod to slide on the other side clamping plate, screwing a fixing bolt on a clamping ring after the side clamping plate clamps the track, and fixing the synchronous guide rod to complete width measurement and center point positioning of a track surface on the track; after the center point is positioned, marking a mark at the contact position of the line drawing opening included angles at the two end parts of the centering plate and the rail surface by using a stone pen; and disassembling the track measuring and centering device, and connecting the two marked mark points by using a ruler to finally finish the track measuring and center line scribing work.

It is understood that the method of the orbit measurement centering has the same advantages as the device of the orbit measurement centering, and the detailed description thereof is omitted.
Referring to fig. 4, it should be noted that, when the device for centering rail measurement is used, since the two side clamping plates 2 cannot be in close contact with each other, a certain gap exists between the two side clamping plates 2, and when the width of the rail surface 1 on the rail is measured, the gap existing between the side clamping plates 2 needs to be properly subtracted to obtain accurate width data of the rail surface 1 on the rail. In particular, as can be seen from fig. 4, when the device for track measurement and centering is in a closed state, due to the clamping grooves 11 arranged on the two side clamping plates 2, that is, after the two side splints 2 are attached, because the clamping grooves 11 are groove structures, the two opposite side walls of the two clamping grooves 11 cannot be attached, so that the readable data on the synchronous guide rod 7 has a certain original reading, i.e., the spacing a between the opposing sidewalls of the two card slots 11, because of the existence of the original reading a, when measuring the width data of the rail surface 1 on the rail, the original reading a is added, the difference between the first reading on the synchronous guide rod 7 when the two side clamping plates 2 are jointed and the second reading on the synchronous guide rod 7 when the two side clamping plates 2 are opened, namely, the second reading plus the original reading a minus the first reading is the final track upper surface 1 width data, and the accurate track upper surface 1 width data can be obtained through the above operation. In specific implementation, when the two side clamping plates 2 are attached, the first reading on the synchronous guide rod 7 is 0, that is, the width data of the rail surface 1 on the rail is obtained by only adding the second degree to the original reading a.
It will be appreciated that it will be clear to those skilled in the art how to obtain accurate track face 1 width data on a track when using the apparatus in track measurement centering described in the above embodiments.
It should be noted that the above-mentioned track measuring and centering device and method are not only applicable to centering operation of various types of tracks, but also applicable to centering operation of various types of section steel, pipelines and plate-shaped structural members, and those skilled in the art should understand how to apply the above-mentioned track measuring and centering device and method to centering operation of various types of section steel, pipelines and plate-shaped structural members.
