Abstract
Description
Technical Field
[0001] This utility model relates to a positioning template for rail splicing line installation, belonging to the technical field of auxiliary installation tools for rail splicing lines. Background Technology
[0002] Rail splicing lines are an important component of track circuits. By connecting two rails, they allow current to flow smoothly through the rails, thus ensuring the integrity and continuity of the track circuit.
[0003] When installing rail splice lines, holes need to be drilled on two rails. The position of the holes on the two rails determines the installation position of the rail splice line. If the positions of the holes on the two rails are off, the rail splice line will not be straight, and the appearance quality will be poor and it will be easy to break. After it is put into use, it may endanger the safety of train operation. Utility Model Content
[0004] The purpose of this utility model is to provide a rail splice installation positioning template that can quickly and accurately determine the installation position of the rail splice, thus solving the problems existing in the background art.
[0005] The technical solution of this utility model is: A rail splice installation positioning template includes a right crossbar, a left crossbar, a middle gripping handle, a fixed marking pen, a movable marking pen, a fixed bolt, a movable bolt, a fixed nut, a movable nut, and a scale. The right and left crossbars are threadedly connected to the two ends of the middle gripping handle. The fixed marking pen is fixed to the left crossbar by the fixed bolt and the fixed nut. The movable marking pen is movably connected to the right crossbar by the movable bolt and the movable nut. The right crossbar is provided with a scale that cooperates with the movable marking pen.
[0006] The left crossbar has a fixing bolt hole that mates with the fixing bolt, and the right crossbar has a movable bolt hole that mates with the movable bolt. The fixed marker pen and the movable marker pen are respectively fixed to the fixing bolt and the movable bolt by clips.
[0007] The fixing bolt hole on the left crossbar that mates with the fixing bolt is a threaded round hole, and the movable bolt hole on the right crossbar that mates with the movable bolt is a threaded elongated hole along the length of the right crossbar.
[0008] The two ends of the middle grip handle are respectively threaded to the right crossbar and the left crossbar via screws.
[0009] The beneficial effects of this utility model are: it is simple to manufacture, low in cost, and easy to disassemble and collect; it can quickly and accurately determine the installation position of the rail splice line. It saves installation time and avoids the situation where drilling holes on one side of the rail reveals that drilling at the correct distance on the other side is not possible. The installed rail splice line is flat and without deformation, requiring no secondary correction, thus preventing installation deformation from causing breakage of the rail splice line and affecting its service life. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of this utility model; In the diagram: Right horizontal bar 1, Left horizontal bar 2, Middle grip handle 3, Fixed marker pen 4, Movable marker pen 5, Fixed bolt 6, Movable bolt 7, Fixed nut 8, Movable nut 9, Fixed bolt hole 10, Movable bolt hole 11, Screw hole 12, Scale 13, Buckle 14, Screw 15. Detailed Implementation
[0011] The present invention will be further described below with reference to the accompanying drawings and examples.
[0012] See attached document Figure 1 A rail splice installation positioning template includes a right crossbar 1, a left crossbar 2, a middle gripping handle 3, a fixed marking pen 4, a movable marking pen 5, a fixed bolt 6, a movable bolt 7, a fixed nut 8, a movable nut 9, and a scale 13. The right crossbar 1 and the left crossbar 2 are threadedly connected to the two ends of the middle gripping handle 3. The fixed marking pen 4 is fixed to the left crossbar 2 by the fixed bolt 6 and the fixed nut 8. The movable marking pen 5 is movably connected to the right crossbar 1 by the movable bolt 7 and the movable nut 9. The right crossbar 1 is provided with a scale 13 that cooperates with the movable marking pen 5.
[0013] In this embodiment, refer to the appendix Figure 1 The rail splice installation positioning template includes a right crossbar 1, a left crossbar 2, a middle gripping handle 3, a fixed marking pen 4, a movable marking pen 5, a fixed bolt 6, a movable bolt 7, a fixed nut 8, a movable nut 9, a fixed bolt hole 10, a movable bolt hole 11, a screw hole 12, a scale 13, a buckle 14, and a screw 15, wherein: The diameter of the middle part of the right crossbar 1 is smaller than the diameter of the two ends. The middle part of the right crossbar 1 is provided with a scale 13 for the movable marker pen 5 to move a distance, and is also provided with a movable bolt hole 11. The movable bolt hole 11 is a threaded long strip hole along the length direction of the right crossbar 1. The positioning position of the movable bolt 7 is adjusted through the threaded long strip hole.
[0014] The fixing bolt hole 10 on the left crossbar 2 is a threaded round hole, and the fixing bolt 6 is positioned on the fixing bolt hole 10 by the fixing nut 8.
[0015] The fixed marker 4 and the movable marker 5 are fixed to the fixed bolt 6 and the movable bolt 7 respectively by the clip 14.
[0016] In use, the fixed marking pen 4 and the movable marking pen 5 are used to mark the positions at the joints of the two rails, thereby enabling the rapid installation and positioning of the drilling positions for the rail splice.
