The utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, as long as there is no conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

As shown in Figure 1, a measurement tool for the reconstruction of existing line platforms includes a measuring line 5, a foot plate 1 and a connecting plate 2. The two foot plates 1 are distributed in parallel and spaced apart. The distance between the two foot plates 1 is equal to the width of the railway track. Adapted, the two ruler boards 1 are respectively blocked on both sides of the existing railway track, thereby connecting the existing line as a whole. The positional relationship between the existing line and the platform is reflected through measuring tools, and the measurement method is simple and efficient.

Both ends of the two ruler plates 1 are connected by connecting plates 2 to connect the two ruler plates 1 as a whole, so that the two connecting plates 2 can be stably buckled on the rails, thereby avoiding the occurrence of accidents during the measurement process. displacement; one end of the measuring line 5 is connected to the outside of the ruler plate 1 on the side away from the platform, and the other end is wound on the hand wheel 6. The measuring line 5 should be non-conductive and have small elastic variables, such as cotton thread or coating on the outer wall of the steel wire. An insulation layer is installed to form a line, and a scale mark is provided on the measuring line 5, so that the distance between the station and the existing line can be quickly read to facilitate measurement and re-measurement.

There is a positioning groove 6 on the ruler plate 1 on the side close to the platform. The positioning groove 6 is perpendicular to the ruler plate 1. The same displacement in the length direction of the measuring tool corresponds to the measuring line 5. When the measuring line 5 passes through the positioning groove 6 After straightening, the measuring line 5 is exactly perpendicular to the ruler board 1, that is, the measuring line 5 is perpendicular to the existing line, which can accurately reflect the positional relationship of the platform.

In this embodiment, the bottom of the positioning groove 6 and the upper surface of the other tooth plate are on the same horizontal plane.

Preferably, a laser pointer parallel to the extension direction of the positioning groove 6 is provided on the ruler plate 1 , so that the measuring line 5 can be more accurately parallel to the ruler plate 1 .

In this embodiment, at least one connecting plate 2 is provided with a level bubble 7 to keep the measuring tool horizontal, thereby ensuring the accuracy of the measurement data.

In an optional embodiment, in order to ensure the accuracy of the measurement, there are two measuring lines 5. The two measuring lines 5 are located at both ends of the two ruler plates 1. The measurements of the two measuring lines 5 are mutually verified. This ensures measurement accuracy. In addition, the same measurement tool can measure two measurement points at the same time, improving measurement efficiency.

In an optional embodiment, in order to quickly buckle the ruler plate 1 on the rail, a chute is provided on the bottom surface of the connecting plate 2. The chute is perpendicular to the ruler plate 1 and extends along the length direction of the connecting plate 2. The plate 1 extends upward and has a slider assembled in the chute. The two ruler plates 1 slide along the chute so that the distance between the two ruler plates 1 can be adjusted. The slider has a certain thickness, so that the distance between the two ruler plates 1 can be adjusted. Keep the two ruler plates 1 parallel during the sliding process.

In this embodiment, the chute is a dovetail groove and the slider is in a dovetail shape. The dovetail-shaped trough body can ensure that it will not fall off in the longitudinal direction during the sliding process. Limiting studs 3 are provided at both ends of the connecting plate 2 , the limit stud 3 extends along the extension direction of the chute, and resists on the side of the slider that is far away from each other, so that the distance between the two ruler plates 1 is limited by the limit stud 3, so that the two ruler plates 1 pass through the limit. The extrusion of the studs 3 clamps both sides of the rail, ensuring that the ruler plate 1 is close to the rail under the premise of disassembly, thereby improving the accuracy of measurement.

In this embodiment, baffles are fixed at both ends of the connecting plate 2 with screws. The length of the baffle matches the width of the connecting plate 2. The baffles are fixed at both ends of the connecting plate 2 with screws. The chute is provided with screw holes, and the limit stud 3 is threaded on the baffle.
