[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] At present, there is no auxiliary structure when the staff punches holes in the rail. In traditional axle counting hole punching construction, it is easy to have inaccurate positioning points and large deviations in the punching positions, which easily leads to rail damage. In severe cases, even the entire rail needs to be replaced, reducing the installation efficiency and qualification rate of the subway axle counting equipment system.

[0025] To solve the defects existing in the above punching process, please refer to Figures 1-6 , a positioner for subway axle counting installation punching provided by the present invention can accurately mark the punching points, and can adjust the hole spacing according to the installation requirements of the axle counting, improve the accuracy of the punching position, ensure the installation accuracy of the axle counting equipment, and improve the installation efficiency and qualification rate of the subway axle counting equipment system. This positioner is based on a hanger 1. One end of the hanger 1 is fixedly installed with a positioning plate 2, and the other end of the hanger 1 is provided with a clamping piece 3 for fixing the positioning plate 2 on the rail. A sliding groove 5 is opened on the positioning plate 2, and a positioning mechanism 6 for marking the hole positions of the rail is symmetrically arranged in the sliding groove 5. And an adjusting mechanism 9 for adjusting the distance between the two positioning mechanisms 6 is arranged in the positioning plate 2. The whole device is fixed on the rail through the clamping piece 3, so that the positioning plate 2 is attached to the waist of the rail. Then, according to the installation requirements of the axle counting, the distance between the two positioning mechanisms 6 is adjusted through the adjusting mechanism 9, and the hole spacing can be controlled. After the adjustment is completed, the rail is marked by the positioning mechanism 6, and the accurate punching position can be obtained to achieve accurate positioning. Furthermore, the staff can punch holes in the rail according to the marked points, which can ensure the installation accuracy of the axle counting equipment and improve the installation efficiency and qualification rate of the subway axle counting equipment system.

[0026] In order to facilitate the marking of the hole positions on the rail, a carriage 61 is provided. The carriage 61 is slidably installed in the chute 5. The carriages 61 in the two groups of positioning mechanisms 6 are symmetrically distributed about the center line of the chute 5. A marking pen 62 is slidably installed inside the carriage 61. The marking pen 62 is used to mark the rail. A pressing handle 63 is installed at the end of the marking pen 62. A connecting spring 64 is sleeved outside the marking pen 62. One end of the connecting spring 64 is fixedly connected to the pressing handle 63, and the other end of the connecting spring 64 is fixedly connected to the carriage 61. Pressing the pressing handle 63 drives the marking pen 62 to slide towards the rail. When the marking pen 62 contacts the rail, a mark can be left on the surface of the rail. At this time, the connecting spring 64 deforms. After releasing the pressing handle 63, the marking pen 62 can slide back to its original position through the elastic force of the connecting spring 64 and move away from the surface of the rail, thus completing the marking work.

[0027] In order to accurately control the hole spacing, referring to Figure 3 as shown, a pointer 7 is fixedly connected to the center position at the bottom of the carriage 61. A scale line 8 is provided on the side of the positioning plate 2. By driving the two carriages 61 to move away from or close to each other through the adjusting mechanism 9, the distance between the two carriages 61 can be observed through the pointer 7 and the scale line 8, so as to determine the hole spacing and achieve accurate positioning of the drilling position.

[0028] As the marking pen 62 is used, the marking imprint of the marking pen 62 will gradually fade. After long-term use, the marking pen 62 may not be able to effectively mark the rail. At this time, new equipment needs to be replaced, and the overall cost of replacing the equipment is relatively high. To solve this technical problem, referring to Figure 6 as shown, a marking core 622 is movably installed inside the sleeve 621. A colored marking liquid is added to the marking core 622. A marking head 623 is threadedly installed at the end of the sleeve 621. The marking head 623 prevents the marking core 622 from falling off. The marking head 623 is provided with a hollow setting. Pressing the sleeve 621, the marking liquid in the marking core 622 can act on the rail through the marking head 623. When the marking liquid in the marking core 622 is used up, the marking head 623 can be rotated to replace a new marking core 622 and continue to be used, thereby extending the service life of the equipment.

[0029] In order to facilitate the adjustment of the distance between the two marking pens 62, a bidirectional screw 91 is provided. The bidirectional screw 91 is rotatably installed in the positioning plate 2. The threads on the outer surface of the bidirectional screw 91 are two sections with opposite rotation directions. The top of the carriage 61 is threadedly connected to the outer surface of the bidirectional screw 91. One end of the bidirectional screw 91 passes through the positioning plate 2 and is fixedly connected to a knob 92. Anti-slip threads are provided on the outside of the knob 92. Rotating the knob 92 facilitates driving the bidirectional screw 91 to rotate. Since the carriage 61 is slidably connected to the chute 5, the rotation of the bidirectional screw 91 drives the two carriages 61 to slide, so that the two carriages 61 move closer to or away from each other, thereby adjusting the distance between the two marking pens 62 and controlling the hole spacing.

[0030] Since the positioning plate 2 may be displaced on the rail during the use of the device, resulting in blurred and misaligned markings of the marking pen 62 and affecting the accuracy of the punching position, to solve this technical problem, a threaded rod 31 is provided. The threaded rod 31 is threadedly connected to one end of the hanger 1 away from the positioning plate 2, and a pressing piece 32 is fixedly connected to the end of the threaded rod 31. The hanger 1 is clamped on the rail, and rotating the threaded rod 31 can drive the pressing piece 32 to move. The pressing piece 32 presses against the rail and cooperates with the positioning plate 2 to clamp the rail, so that the device can be fixed on the rail, and the automatic displacement of the positioning plate 2 can be avoided, ensuring the accuracy of the punching position.

[0031] Subway lines are usually very long, and it is necessary to install subway axle counters at different locations. To facilitate carrying the device to operate at different work sites, a plurality of weight-reducing grooves 4 are provided on the hanger 1, and a handle 10 is installed at the top of the hanger 1. The opening of the weight-reducing grooves 4 can reduce the overall weight of the device, and it is convenient to lift and move the device through the handle 10, greatly improving the portability of the device.

[0032] The specific implementation process of this embodiment is as follows: During use, the hanger 1 is clamped on the rail, so that the positioning plate 2 is closely attached to the waist of the rail. Rotating the threaded rod 31 drives the pressing piece 32 to press against the rail, and the positioning plate 2 can be fixed on the rail. Subsequently, according to the installation requirements of the axle counter, the distance between the two marking pens 62 is adjusted. Rotating the knob 92 drives the bidirectional screw 91 to rotate, and the rotation of the bidirectional screw 91 drives the two sliding frames 61 to slide in opposite directions. Referring to the pointer 7 and the scale line 8, the distance between the two marking pens 62 can be accurately controlled. After the adjustment is completed, the two pressing handles 63 are pressed, and the pressing handles 63 drive the marking pens 62 to slide towards the rail. When the marking pens 62 contact the rail, marks can be left on the surface of the rail. At this time, the connecting spring 64 is deformed. After releasing the pressing handle 63, the marking pens 62 can slide back to their original positions through the elastic force of the connecting spring 64 and move away from the surface of the rail, completing the marking work. Then, the staff can punch holes in the rail according to the marks, improving the accuracy of the punching position, ensuring the installation accuracy of the axle counter device, and improving the installation efficiency and qualification rate of the subway axle counter device system.
