With further reference to fig. 2-4, the tram rail tensile displacement measurement method includes the following steps:
step S101: and (5) manufacturing a steel ruler.
It should be understood that the step of making the steel rule in step S101 includes: and manufacturing a steel ruler with a corresponding length according to the displacement range of the steel rail 11 needing to be stretched. That is, when the length of the rail 11 to be stretched is in the range of 10-30 cm, a steel ruler with a length greater than 30 cm needs to be manufactured.
In this embodiment, the steel rule includes a level 101 horizontally disposed and a handle 102 vertically connected to the level 101. Preferably, level 101 and handle 102 are integrally formed.
Preferably, the middle scale of level 101 is a zero scale, and the zero scale of level 101 is symmetrically provided with other scales on both sides, it being understood that the other scales include numbers of 1-10, and the units of the numbers are centimeters.
In this embodiment, level 101 is elongated rectangular in shape and handle 102 is elongated rectangular in shape, with handle 102 being disposed in the middle of level 101. Preferably, the end of the handle 102 remote from the level 101 is provided with a mounting plate in which is provided a mounting structure for mounting on the track plate 12, preferably the mounting structure comprising a threaded bore.
Step S102: a pointer 13 is made for being positionable on the rail 11.
Preferably, the step of making a pointer for being disposed on a steel rail in step S102 includes: the pointer 13 which can be adsorbed on the steel rail is made of a magnet material. It will be appreciated that the pointer 13 is made of a magnet material so that the pointer 13 can be attracted to the rail 11.
Step S103: selecting a steel rail 11, selecting a plurality of measuring points on the steel rail 11, making a first mark on the measuring point corresponding to the steel rail 11, and making a second mark on the track plate 12 corresponding to the measuring point.
It should be understood that the step of selecting a plurality of measurement points on the steel rail in step S103 includes: and selecting a plurality of corresponding measuring points on the steel rail 11 according to the length of the steel rail 11. Preferably, the longer the length of the rail 11, the more measurement points are selected, and the shorter the length of the rail 11, the fewer measurement points are selected.
Step S104: the handle 102 of the steel ruler is fixedly arranged on the track slab 12 according to the second mark, the level ruler 101 is arranged in parallel with the steel rail 11 according to the first mark, and the zero scale of the level ruler 101 is aligned with the measuring point.
Step S105: pointer 13 is positioned on rail 11 such that pointer 13 points vertically to the zero scale of level 101 (as shown in fig. 2).
Step S106: the rail 11 is pulled and the displacement parameter indicated by the pointer 13 is read from the level 101 (as shown in fig. 3, the displacement L is the distance the rail 11 is pulled up after the rail 11 is pulled up in the direction a).
Further, the method for measuring the stretching displacement of the tramcar steel rail further comprises the following steps: counting displacement parameters measured by the level ruler 101 of each measuring point on the steel rail 11, and judging whether the displacement parameters are nonstandard; if yes, marking the measuring point on the steel rail 11 with the displacement parameter which is not standard. It should be understood that if the displacement parameter is not standard, it indicates that there is a problem with the rail 11 corresponding to the measurement point, and marking the measurement point red is convenient for the worker to know that there is a problem.
Further, in some embodiments, the level 101 includes a middle portion with zero scale, a first level telescopically disposed at one end of the middle portion, and a second level telescopically disposed at the other end of the middle portion, wherein the handle 102 is vertically disposed in the middle portion. It should be understood that, because the first level and the second level are telescopically arranged, the scales on the first level and the second level are represented by a plurality of vertical bars arranged at intervals, no digital scale is displayed, and therefore one vertical bar represents 1 centimeter, 2 vertical bars represent 2 centimeters and the like, and so on. Therefore, when the steel ruler with the corresponding length is manufactured according to the displacement range of the steel rail needing to be stretched, the expansion and contraction of the first horizontal ruler and the second horizontal ruler are mainly controlled according to the displacement range of the steel rail needing to be stretched.
In conclusion, the stretchy displacement measuring method for the tramcar steel rail disclosed by the invention has the advantages of short construction period, low cost, simplicity in installation, capability of measuring by a plurality of measuring points and high measuring precision.
