[0002] A turnout is a line connection device that allows motor vehicles to switch from one track to another. During installation and subsequent maintenance, in order to ensure the squareness of the turnout, a railway ruler is needed to check it. However, since the ruler is nearly two meters long, it is not very convenient to carry and operate. In order to improve convenience, laser squareness detection of turnouts is gradually being used.

[0003] For example, in the patent document with patent publication number CN205856948U, an infrared turnout square measuring instrument is disclosed, which includes a laser level, a steering plate, a right-angle plate, stud bolts, horizontal adjustment screws, parallel adjustment screws, a vertical positioning pointer and a magnet. The stud bolts pass through the convex through holes on the steering plate and the convex through holes on the right-angle plate respectively and are connected together with nuts. The threaded holes of the laser level base are connected to the stud bolts to install and fix the laser level on the steering plate.

[0004] According to the existing technical literature, the measuring instrument is adsorbed on the rail by magnets to fix the overall structure, and then the measuring instrument can be leveled by adjusting the horizontal adjustment screw and the parallel adjustment screw to ensure the accuracy of laser measurement. However, during the leveling process, the horizontal adjustment screw and the parallel adjustment screw need to be adjusted manually and repeatedly, which has low leveling efficiency. At the same time, the leveling operation is not easy to perform under the adsorption of the magnet.

[0028] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 7 as shown in .

[0029] A square laser detector for a turnout comprises a mounting plate 1, a slide rail group is fixedly connected to the middle part of the top surface of the mounting plate 1 along its length direction, a slide plate 2 is movably mounted on the slide rail group, support plates 3 are vertically fixedly connected to the tops of the two ends of the slide plate 2, rotating holes are coaxially opened at corresponding positions of the upper ends of the two support plates 3, and a rotating shaft 4 is also included, the shaft bodies on the left and right sides of the rotating shaft 4 are movably inserted into the rotating holes of the support plates 3 at corresponding positions, a laser assembly is fixedly provided on the top of the middle section of the rotating shaft 4, a counterweight assembly is fixedly provided on the bottom of the middle section of the rotating shaft 4, clamping assemblies for clamping the corresponding ends of the rotating shaft 4 are respectively provided on the tops of the left and right ends of the mounting plate 1, and a positioning assembly is provided at the bottom of the mounting plate 1.

[0030] The detector is positioned by the positioning assembly at the bottom of the mounting plate 1, and is fixed on the straight base rail at the station to be inspected, while being kept parallel to the straight base rail there, thereby ensuring that the laser emitted by the laser assembly is perpendicular to the straight base rail there, thereby ensuring the accuracy of the detector when performing square detection on turnout components such as turnout angle steels and inner locking turnout rods.

[0031] By sliding the slider 2 along the slide rail assembly, the two support plates 3 can be driven to move horizontally accordingly, thereby driving the rotating shaft 4, the laser assembly and the counterweight assembly to move synchronously. In this way, when the positioning assembly completes the positioning, the position of the laser assembly can be fine-tuned through the cooperation and connection of the slide rail assembly and the slider, avoiding repeated movement of the detector, so that the laser emitted by the laser assembly is aligned with the edge of the corresponding angle steel, the inner locking turnout rod and the waiting detection structure, so as to facilitate observation of whether it is square.

[0032] The lower ends of the support plates 3 are fixedly connected to the corresponding ends of the slide plate 2, and a bearing is fixedly installed in the mounting hole on the upper part of the support plate 3. The rotating shaft 4 passes through the bearing shaft hole and is connected to it by a key connection. In this way, under the support of the left and right support plates 3 and the cooperation of the corresponding bearings, the rotating shaft 4 can freely rotate around its axis. At the same time, the overall weight of the counterweight assembly is heavier than the overall weight of the laser assembly. Therefore, under the action of the counterweight assembly, the rotating shaft 4 will automatically rotate without external interference, so that the counterweight assembly rotates and moves to the bottom of the rotating shaft 4, and then the laser assembly rotates and moves to the top of the rotating shaft 4, thereby completing the leveling operation of the laser assembly, so that the laser emitted by the laser assembly can be automatically adjusted to a horizontal position.

[0033] After the leveling operation is completed, in order to ensure the stability of the laser assembly and prevent it from shaking, the end of the rotating shaft 4 is automatically clamped and positioned by the clamping assembly, thereby limiting the rotational movement of the laser assembly.

[0034] In any of the above schemes, it is preferred that the clamping assembly includes a connecting frame 5, an installation space 6 is formed in the middle of the connecting frame 5, and telescopic clamps are respectively provided in the horizontal direction on both sides of the installation space 6, the two telescopic clamps are symmetrically arranged about the vertical center line of the connecting frame 5, and the inner ends of the two telescopic clamps are used to clamp the ends of the rotating shaft 4.

[0035] The rotating shaft 4 passes through the installation space 6 in the middle of the connecting frame 5, and the two telescopic clamping members are respectively located on both sides of the axial direction of the rotating shaft 4. The telescopic clamping member can automatically telescope in the horizontal direction, and when its inner end is extended to a specified position in the installation space 6, it presses against the rotating shaft 4, so that the rotating shaft 4 is clamped and fixed under the joint action of the telescopic clamping members on both sides.

[0036] In any of the above schemes, it is preferred that the telescopic clamping member includes a telescopic cylinder 7, the fixed end of the telescopic cylinder 7 is fixedly connected to the vertical inner wall at the corresponding position of the connecting frame 5, the telescopic end of the telescopic cylinder 7 extends horizontally to the middle of the installation space 6, and a clamping block 8 is fixedly connected to the telescopic end of the telescopic cylinder 7, and a semicircular pressing groove 9 is opened on the inner side of the clamping block 8. In the clamping state, the surface of the semicircular pressing groove 9 fits and presses at the corresponding position of the circumferential outer surface of the end of the rotating shaft 4.

[0037] The telescopic rod of the telescopic cylinder 7 is extended, driving the clamping block 8 to move horizontally until the semicircular pressing groove 9 on the inner side thereof is fitted and buckled onto the shaft body at the end of the rotating shaft 4. At the same time, anti-slip grooves are provided on the inner surface of the semicircular pressing groove 9 to increase the friction between the clamping block 8 and the rotating shaft 4. With the synchronous extension and retraction of the two telescopic cylinders 7, the corresponding clamping block 8 can be driven to approach or move away from the rotating shaft 4 accordingly, thereby finally achieving the clamping, fixing or releasing of the rotating shaft 4.

[0038] In any of the above schemes, preferably, the counterweight assembly includes a connecting rod 10, the upper end of which is fixedly connected to the bottom of the circumferential outer surface of the middle section of the rotating shaft 4, and a counterweight block 11 is integrally formed at the lower end of the connecting rod 10.

[0039] The connecting rod 10 is perpendicular to the rotating shaft 4 and is welded and fixedly connected therebetween. When the two sets of clamping blocks 8 release the rotating shaft 4 so that it can resume free rotation, under the action of the weight of the counterweight block 11, the connecting rod 10 finally rotates to the vertical direction under the connection with the rotating shaft 4, thereby driving the rotating shaft 4 to rotate accordingly, and further driving the laser assembly to rotate to the specified position.

[0040] In any of the above schemes, it is preferred that the laser assembly includes a first connecting plate 12, a plurality of second connecting plates 13 are fixedly connected at intervals at the bottom of the first connecting plate 12, the mounting holes of each of the second connecting plates 13 are respectively fixedly sleeved at corresponding positions on the circumferential outer surface of the rotating shaft 4, a controller 14 is fixedly installed on the top of the first connecting plate 12, a laser emitter 15 is fixedly installed on the top of the controller 14, and a switch 16 is fixedly provided on one side of the top of the controller 14.

[0041] The controller 14 is an existing structure. In addition to the control mainboard for controlling the operation of the laser emitter 15, a battery module is also integrated inside it to power the laser emitter 15. The laser emitter 15 can be turned on and off by the switch 16. The laser emitter 15 is fixedly installed on the top of the controller 14 in a direction perpendicular to the rotating shaft 4. When it is working, it can emit laser in a direction perpendicular to the rotating shaft 4, so as to detect the squareness of the turnout angle steel and the inner locking turnout rod waiting for the detection structure. At the same time, the laser emitted by the laser emitter 15 is a green laser. Compared with infrared laser, green laser is easier to be observed by the naked eye under sunlight.

[0042] In any of the above schemes, it is preferred that the positioning assembly includes a plurality of magnets 17, a plurality of mounting grooves 18 are spaced apart at the bottom of the mounting plate 1, each of the magnets 17 is respectively arranged in the inner cavity of the corresponding mounting groove 18, and a cover plate 19 for sealing each of the mounting grooves 18 is fixedly connected to the bottom of the mounting plate 1.

[0043] A cover plate matching groove is provided at the bottom of the mounting plate 1, and three mounting grooves 18 are evenly spaced in the cover plate matching groove. After three corresponding magnets 17 are respectively placed in the mounting grooves 18, a cover plate 19 is placed in the cover plate matching groove, and the cover plate 19 is fixedly connected to the mounting plate 1 by bolts, thereby sealing the mounting grooves 18 and the magnets 17. The cover plate 19 is kept flush with the bottom of the mounting plate 1, so that the detector can be placed on the rail surface more stably.

[0044] In any of the above solutions, preferably, a positioning plate 20 is fixedly connected to one side of the bottom surface of the mounting plate 1 along its length direction.

[0045] When the detector is placed on the surface of the straight base rail, the positioning plate 20 abuts against the side of the straight base rail, thereby assisting the initial positioning work and ensuring that the detector can be placed along the length direction of the straight base rail.

[0046] In any of the above schemes, it is preferred that the slide rail group includes a plurality of T-shaped slide rails 21 arranged at intervals along the width direction of the mounting plate 1, each of the T-shaped slide rails 21 is arranged along the length direction of the mounting plate 1, and T-shaped slide grooves 22 are respectively opened at corresponding positions on the bottom of the slide plate 2, and each of the T-shaped slide rails 21 is respectively slidably connected with the T-shaped slide grooves 22 at the corresponding positions.

[0047] There are two T-shaped guide rails 21 and two corresponding T-shaped guide grooves 22 . The slider 2 can slide horizontally along the T-shaped guide rails 21 through the matching connection between the T-shaped guide rails 21 and the T-shaped guide grooves 22 .

[0048] In any of the above solutions, it is preferred that the telescopic cylinder 7 is an electric cylinder, and batteries 23 are fixedly mounted on the tops of both ends of the mounting plate 1 respectively.

[0049] In order to realize the convenience of the detector, the telescopic cylinder 7 is selected as an electric cylinder, and a battery 23 is arranged at the corresponding end position of the mounting plate 1 to supply power to the electric cylinder at that location.

[0050] Specific working principle:

[0051] The operator first places the detector on the straight basic rail to be detected by visual inspection, and through the adsorption of the magnet 17, the mounting plate 1 is fixed on the top surface of the rail, and the positioning plate 20 is abutted against the side of the rail, so that the detector is parallel to the straight basic rail. Then, through the movable connection between the T-type slide rail 21 and the T-type slide groove 22, the slide plate 2 is moved, so as to fine-tune the position of the laser emitter 15, and then the laser emitter 15 is moved to the edge position of the structure such as the angle steel and the inner locking switch rod to be detected. At the same time, under the action of the counterweight block 11, the rotating shaft 4 is automatically rotated, and then the laser emitter 15 is leveled, so that the laser emitted by it is in the horizontal direction. Then the telescopic cylinder 7 is controlled to extend and drive the corresponding clamping block 8 to move, so as to complete the clamping and fixing of the end of the rotating shaft 4, and further ensure the stability of the laser emitter 15. At this time, the laser emitted by the laser emitter 15 is aligned with the edge of a section of the structure to be detected, and the other end is observed to be aligned, so as to detect whether the structure is installed squarely.
