Description

Technical Field

[0001] This utility model relates to the field of railway inspection technology, specifically to a portable laser stringer for railway tracks. Background Technology

[0002] With the rapid development of my country's railway transportation, the country's railway mileage has reached 130,000 kilometers. During rail laying, it is necessary to adjust the position of the rails to ensure that their deviation in the directional and vertical directions is within the required range. As the service life increases, rails in some sections may experience bending, settling, or other deformations, causing parameters such as directional and vertical deviations to exceed the initial safety design specifications. This can lead to a series of potential safety hazards, necessitating adjustments to correct any unevenness in the directional and vertical directions.

[0003] To adjust the unevenness of the rail alignment and elevation, a laser stringing device for rails is required. The current laser stringing device consists of three parts: a laser emitter, a moving target, and a target. These parts are usually placed separately during transport and storage, which makes them prone to loss and renders the device unusable. Utility Model Content

[0004] To overcome the aforementioned technical problems, the purpose of this utility model is to provide a portable laser string for track use. By providing storage slots at both ends of the transmitter base, it is easy to insert the target positioning target and the moving positioning target into the storage slots. The movable plate can drive two locking pins to move and embed into the positioning holes of the target base, thereby facilitating the positioning of the two target bases. This allows the target positioning target and the moving positioning target to be stored and fixed at both ends of the laser transmitter. The portable handle makes it easy to carry the laser string device and store it as a whole, thus preventing the loss of some moving targets and the target.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A portable laser string for track use includes a laser emitting mechanism, with a target positioning target and a moving positioning target respectively provided at both ends of the laser emitting mechanism;

[0007] The laser emitting mechanism includes a transmitter base, a mounting base fixedly connected to the top of the transmitter base, a laser emitter fixedly connected to the top of the mounting base, storage slots at both ends of the transmitter base, a C-shaped plate fixedly connected to the top of the transmitter base, and a portable handle fixedly connected to the top of the C-shaped plate.

[0008] Furthermore, both the target positioning target and the moving positioning target include a target base. An embedded seat is fixedly connected to the top of the target base, and a light spot receiving plate is slidably engaged in the embedded seat. The target base is slidably engaged with the storage groove. Two magnetic strips are symmetrically fixedly arranged at the bottom of the target base. By providing two magnetic strips at the bottom of the target base, the rail can be magnetically attracted.

[0009] Furthermore, the launcher base has movable plates on both sides along its length. The inner walls of both ends of the two movable plates are fixedly connected with locking pins that slide into the launcher base. The target base has positioning holes on opposite side walls that are inserted into the locking pins. A pull rod is fixedly connected to the center of the movable plate. The pull rod can pull the movable plate to move, so that the two locking pins on the side walls of the movable plate can be pulled out from the positioning holes of the target base, so that they no longer limit the positioning target and the movable target.

[0010] Furthermore, four suction cups are symmetrically and fixedly connected to the bottom of the transmitter base about its vertical center plane. The suction cups at the bottom of the transmitter base can improve the adhesion and stability of the bottom of the transmitter base.

[0011] Furthermore, the portable handle is fitted with an anti-slip sleeve, which improves the anti-slip performance of the handle.

[0012] Furthermore, the movable plate is symmetrically slidably connected with two limiting posts, and each of the two limiting posts is fitted with a return spring that is fixedly connected to the movable plate. The return spring can pull the movable plate and the two locking posts to move. The locking posts can be inserted into the positioning holes on the side wall of the target base, thereby facilitating the storage and fixing of the target positioning target and the movable positioning target.

[0013] The beneficial effects of this utility model are:

[0014] 1. By providing storage slots at both ends of the transmitter base, it is easy to insert the target positioning target and the moving positioning target into the storage slots. The moving plate can drive the two locking pins to move and embed into the positioning holes of the target base, thereby facilitating the positioning of the two target bases. This allows the target positioning target and the moving positioning target to be stored and fixed at both ends of the laser transmitter. The portable handle makes it easy to carry the laser string device and store it as a whole, thus preventing the loss of some moving targets and the target. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figure 1-4 As shown, the track uses a portable laser string, including a laser emitting mechanism 100, with a target positioning target 210 and a moving positioning target 220 respectively provided at both ends of the laser emitting mechanism 100.

[0023] The laser emitting mechanism 100 includes an emitter base 101, a mounting base 102 fixedly connected to the top of the emitter base 101, a laser emitter 103 fixedly connected to the top of the mounting base 102, storage slots 108 at both ends of the emitter base 101, a U-shaped plate 104 fixedly connected to the top of the emitter base 101, and a portable handle 105 fixedly connected to the top of the U-shaped plate 104; movable plates 109 are provided on both sides of the emitter base 101 along its length, and locking pins 110 that slide and insert into the emitter base 101 are fixedly connected to the inner walls of both ends of the two movable plates 109; positioning holes 213 that insert into the locking pins 110 are provided on the opposite side walls of the target base 211. A pull rod 111 is fixedly connected to the center of the movable plate 109. The pull rod 111 can pull the movable plate 109 to move, so that the two locking pins 110 on the side wall of the movable plate 109 can be pulled out from the positioning hole 213 of the target base 211, so that it no longer limits the positioning target and the movable target. Four suction cups 107 are fixedly connected to the bottom of the launcher base 101 symmetrically about its vertical center plane. The suction cups 107 on the bottom of the launcher base 101 can improve the adsorption and stability of the bottom of the launcher base 101. The portable handle 105 is fixedly sleeved with an anti-slip sleeve 106. The anti-slip sleeve 106 on the outside of the portable handle 105 can improve the anti-slip performance of the handle.

[0024] Both the target positioning target 210 and the moving positioning target 220 include a target base 211. An embedded seat 214 is fixedly connected to the top of the target base 211. A light spot receiving plate 215 is slidably engaged in the embedded seat 214. The target base 211 is slidably engaged with the storage slot 108. Two magnetic strips 212 are symmetrically fixedly arranged at the bottom of the target base 211. The two magnetic strips 212 at the bottom of the target base 211 can magnetically attract the rail. Two limiting posts 112 are symmetrically slidably connected on the moving plate 109. A return spring 113 fixedly connected to the moving plate 109 is sleeved on the outside of the two limiting posts 112. The return spring 113 can pull the moving plate 109 and the two engaging posts 110 to move. The engaging posts 110 can be inserted into the positioning holes 213 on the side wall of the target base 211, which can facilitate the storage and fixing of the target positioning target 210 and the moving positioning target 220.

[0025] Working principle: During use, the moving plate 109 is pulled by the pull rod 111, which causes the locking pin 110 to be pulled out from the positioning hole 213 on the side wall of the target base 211. Then, the target positioning target 210 and the moving positioning target 220 can be pulled out from both ends of the transmitter base 101. When detecting unevenness of the rail, the laser transmitter base 101 needs to be placed on the top surface of the rail so that the suction cup 107 at the bottom of the transmitter base 101 can adhere to the rail, thereby improving the stability of the laser emitting mechanism 100. Then, the target positioning target 210 is placed on the top surface of the rail about 30 meters away from the transmitter base 101. The laser emitter 103 emits a laser beam that illuminates the center of the light spot receiving plate 215. Then, the moving positioning target 220 is placed on the top surface of the rail that needs to be adjusted, and the position of the laser spot is observed. If the laser is below the center line of the light spot receiving plate 215 of the moving positioning target 220, the section of rail needs to be lowered. If the laser spot is above the center line, the section of rail needs to be raised.

[0026] When inspecting the rail alignment, the laser emitting mechanism 100 is first placed on the side of the rail, and then the target positioning target 210 is placed about 30 meters away from the laser emitting mechanism 100, so that the magnetic strip 212 at the bottom of the target positioning target 210 can be attracted to the side of the rail. The laser emitting device 103 is turned on so that the laser shines on the center position of the light spot receiving plate 215 on the target positioning target 210. Then, the moving positioning target 220 is attracted to the side of the rail section that needs to be adjusted. The direction of the light spot on the light spot receiving plate 215 on the moving positioning target 220 deviating from the center line is observed, and the rail section is oriented and adjusted until the light spot is located at the center line of the light spot receiving plate 215, at which point the pointing point construction is completed.
