Abstract
Description
Technical Field
[0001] This utility model relates to the field of track testing technology, specifically a track leveling test vehicle. Background Technology
[0002] During its service life, the track is subject to ground settlement due to various factors such as soil conditions. This settlement causes the transport track to undulate, posing a significant risk to the operation of the beam transport vehicle. When the beam transport vehicle passes over a subsided section, it is highly likely to cause serious accidents, such as beam tilting. This would disrupt the beam's structural balance and affect subsequent construction progress. More seriously, it could lead to beam breakage, resulting not only in material waste but also in project delays, significant economic losses, and safety risks.
[0003] In terms of detecting track levelness, existing technologies rely on track inspection trolleys. However, existing track trolleys have many shortcomings. They cannot be matched to tracks of different widths according to requirements, lacking flexibility in practical applications. Moreover, they cannot quickly level themselves during the inspection process, which greatly affects inspection efficiency. Due to the variability in track conditions, track widths may differ between projects. If the trolley is not adaptable, additional tools or adjustments to the inspection plan are required, consuming more time and effort. Furthermore, the slow leveling speed directly slows down the entire inspection process, making track levelness inspection work sluggish and unable to meet the needs of rapid engineering construction. Therefore, we propose a track leveling testing vehicle. Utility Model Content

Threaded holes are opened on the right side of the moving bars 22, with opposite threads. The bidirectional screw 23 is threaded inside the two threaded holes and welded together from two oppositely threaded rods. The bidirectional screw 23 is rotatably connected inside the fixed frame 21. Limiting holes are opened on the left side of the moving bars 22, with a limiting rod 24 slidably connected inside the two limiting holes. The limiting rod 24 is fixed inside the fixed frame 21. The first motor 25 is mounted on the front side of the fixed frame 21, and the output shaft of the first motor 25 is fixed to the upper end of the bidirectional screw 23. A connecting frame 26 is fixed to the lower side of the moving bars 22. The connecting frame 26 has a moving component 3 installed on its side. The moving component 3 and the detection component 4 correspond to each other. The moving component 3 includes a slide frame 31, a second motor 32, a gear 33, a toothed plate 34, a mounting frame 35, and track wheels 36. The side of the connecting frame 26 has a sliding hole, and the slide frame 31 is slidably connected inside the sliding hole. Two corresponding second motors 32 are installed on the side of the connecting frame 26. The gear 33 is fixed on the output shaft of the second motor 32.

[0026] The mounting plate 1 has a protective shell 5 fixed on its upper side. The upper side of the protective shell 5 has an opening, and a baffle 13 is hinged inside the opening. An alarm 6 is installed on the upper side of the protective shell 5. The input terminal of the alarm 6 is electrically connected to the output terminal of the PLC controller 12. The alarm is triggered by setting the alarm 6.
[0027] Specifically: A pusher 7 is fixed to the right side of the mounting plate 1, and two corresponding push rods 8 are fixed to the side of the pusher 7. The user can move the mounting plate 1 by pushing the pusher 7 and the push rods 8.
[0028] Wherein: the input terminal of PLC controller 12 is electrically connected to the output terminal of battery 10, and the input terminal of PLC controller 12 is electrically connected to the output terminals of first motor 25, level detector 9 and data storage device 11 respectively.
[0029] The working principle of the track leveling test vehicle provided by this utility model is as follows: During use, the first motor 25 can be started according to the width of the track. After the first motor 25 is started, the bidirectional screw 23 rotates. The rotation of the bidirectional screw 23 drives the two moving bars 22 to move. The movement of the two moving bars 22 drives the two connecting frames 26 to move. The movement of the two connecting frames 26 adjusts the position of the four track wheels 36. After adjustment, the four track wheels 36 can fit the track of different widths. After the track wheels 36 fit the track, the leveling instrument 9 can detect the levelness of the mounting plate 1. After detection, the PLC controller 12 will automatically control the corresponding second motor 32 to work according to the requirements. The second motor 32 drives the gear 33 to rotate. The rotation of the gear 33 drives the toothed plate 34 meshing with it to move. The movement of the toothed plate 34 drives the sliding frame 31 to move. The sliding frame 31 moves, driving the track wheel 36 connected to it to move. In this way, the level of the mounting plate 1 can be quickly adjusted. If the position of the sliding frame 31 is not adjusted during the adjustment process, the PLC controller 12 will automatically shut down the corresponding second motor 32 when the sliding frame 31 comes into contact with the pressure sensor 42. This will prevent damage to the sliding frame 31. After adjustment, the mounting plate 1 is moved by the push rod 8. The movement of the mounting plate 1 will drive the level detector 9 to move. The movement of the level detector 9 will detect the level of the track. If the level of the track changes during the detection process, the PLC controller 12 will automatically control the alarm 6 to work to remind the user that the track level has deviated. At the same time, the detected level data will be stored in the data storage 11 for later adjustment.
[0030] It is worth noting that the PLC controller 12 disclosed in the above embodiments is specifically a Siemens S7-200. The first motor 25, the second motor 32, the alarm 6, the data storage device 11, the level detector 9, the water tank 10, and the pressure sensor 42 can be freely configured according to the actual application scenario. The PLC controller 12 controls the first motor 25, the second motor 32, the alarm 6, the data storage device 11, and the level detector 9 using methods commonly used in the prior art.
