Description

Technical Field

[0001] The present application relates to the field of railway detection technology, and in particular to an integrated railway intelligent detection vehicle. Background Art

[0002] Railway tracks are the infrastructure for trains to travel, and the safety of the tracks is directly related to the safety of trains and passengers. By regularly inspecting railway tracks, defects and problems on the tracks can be discovered and repaired in a timely manner to ensure the safety and stability of the tracks.

[0003] Track inspection vehicles are usually used to detect defects and problems on railway tracks. Currently, there are two types of track inspection vehicles: portable track inspection vehicles and large track inspection vehicles. Portable track inspection vehicles are lightweight track inspection equipment that can automatically detect the centerline position, rail top elevation, track gauge, superelevation and other track static parameters based on the pre-input design line type. They are compact and flexible.

[0004] When performing track inspection, the track wheels of the portable track inspection trolley are placed on the corresponding railway tracks, and the portable track inspection trolley is driven to move on the railway tracks to realize the inspection of the railway tracks.

[0005] When the portable track inspection trolley needs to be moved to or from the railway track, the track wheels of the portable track inspection trolley are difficult to move quickly on ordinary roads, making the efficiency of moving the portable track inspection trolley relatively low, so there is room for improvement. Utility Model Content

[0006] In order to improve the mobility of a portable track inspection vehicle on ordinary roads, the present application provides a railway integrated intelligent inspection vehicle.

[0007] The present application provides a railway integrated intelligent inspection vehicle, which adopts the following technical solutions:

[0009] By adopting the above technical solution, when the track inspection trolley needs to be moved or moved out of the railway track, multiple sets of rollers installed on the track inspection trolley can assist the movement of the track inspection trolley, so that the track inspection trolley can move on ordinary roads, thereby improving the movement efficiency of the track inspection trolley.

[0010] Optionally, the rollers are arranged corresponding to the track wheels, and each of the rollers is coaxially arranged on the corresponding rotating shaft.

[0011] By adopting the above technical solution, the roller can be installed on the corresponding rotating shaft, so there is no need to install a rotating structure for the roller to rotate on the track inspection trolley, making the structure simpler and the overall structure more reliable.

[0012] Optionally, each of the rollers can be detachably mounted on a corresponding end of the rotating shaft, and each end of the rotating shaft is provided with a connecting structure for mounting and dismounting the roller.

[0013] By adopting the above technical solution, each roller can be installed and disassembled, which reduces the interference effect that the roller may have on the movement of the track wheel and facilitates the maintenance and replacement of the roller.

[0015] An external thread is arranged on the outer peripheral wall of the rotating shaft near the end, and an internal thread is correspondingly arranged on the inner peripheral wall of the locking sleeve. The locking sleeve can be sleeved outside the rotating shaft to make the internal thread and the external thread lock and fit.

[0016] By adopting the above technical solution, when the roller needs to be installed, the insertion rod is inserted into the slot, and the locking sleeve is screwed onto the outer peripheral wall of the shaft to achieve the installation of the roller.

[0017] Optionally, the end of the insertion rod is arranged to be an outer polygon, and the inner peripheral wall of the slot is arranged to be an inner polygon corresponding to the end of the insertion rod.

[0018] By adopting the above technical solution, the insertion rod can be more firmly inserted into the slot, which greatly reduces the possibility of the insertion rod rotating freely in the slot, improves the insertion stability of the insertion rod and the slot, and makes the installation of the roller more secure.

[0019] Optionally, the track inspection trolley is also provided with a plurality of lifting mechanisms for lifting the track inspection trolley.

[0020] By adopting the above technical solution, the jacking mechanism can lift the track inspection trolley as a whole, so that the track wheels are separated from the ground, making it convenient to install and disassemble the rollers.

[0021] Optionally, the lifting mechanism includes a lifting cylinder and a lifting plate, the lifting cylinder is installed on the track inspection trolley, and the telescopic end is telescopic in a direction perpendicular to the bottom of the track inspection trolley, the lifting plate is located below the bottom of the track inspection trolley, and the telescopic end of the lifting cylinder is fixedly connected to the plate surface of the lifting plate.

[0022] By adopting the above technical solution, when the roller needs to be installed or removed, the lifting cylinder is started, and the lifting cylinder drives the lifting plate to move toward the ground. When the lifting cylinder drives the lifting plate to abut against the ground, the lifting cylinder can cooperate with the lifting plate to lift the track inspection trolley to separate the track wheel from the ground. At this time, the height of the rotating shaft is increased, so that the roller with a larger diameter than the track wheel can be installed and removed more conveniently.

[0023] Optionally, the track inspection trolley is also provided with a flatness detection mechanism for detecting the flatness of the surface of the railway track, and a flaw detection mechanism for detecting internal damage of the railway track.

[0026] 1. When the track inspection trolley needs to be moved or moved out of the railway track, multiple sets of rollers installed on the track inspection trolley can assist the movement of the track inspection trolley, so that the track inspection trolley can move on ordinary roads, thereby improving the movement efficiency of the track inspection trolley;

[0027] 2. Each roller can be installed and disassembled, which reduces the possible interference of the roller on the movement of the track wheel and facilitates the maintenance and replacement of the roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-5 , further details of this application are given.

[0036] The embodiment of the present application discloses a railway integrated intelligent inspection vehicle.

[0037] A railway integrated intelligent inspection vehicle, referring to Figure 1 and Figure 2 , including a track inspection trolley 1, the track inspection trolley 1 includes a base plate 11 and a seat 12 installed on the base plate 11, and also includes a control panel 13 installed on the base plate 11. A plurality of groups of track wheels 14 are arranged at intervals below the base plate 11. In the present embodiment, the track wheels 14 are provided with two front and rear groups, and a rotating shaft 15 for coaxial connection is arranged between the corresponding track wheels 14, and the rotating shaft 15 is rotatably installed at the bottom of the track inspection trolley 1.

[0038] Reference Figure 1 A flatness detection mechanism 2 for detecting the flatness of the surface of the railway track and a flaw detection mechanism 3 for detecting internal damage of the railway track are also provided at the bottom of the track inspection trolley 1 .

[0039] Reference Figure 1 and Figure 2 The flatness detection mechanism 2 includes two groups of laser sensors 21 arranged below the base plate 11 corresponding to the two railway tracks. The laser probes of the two groups of laser sensors 21 are arranged downward and perpendicular to the base plate 11. When the track inspection vehicle 1 moves on the railway track for inspection, it can perform laser detection on the flatness of the railway track surface.

[0040] Reference Figure 1 and Figure 2The flaw detection mechanism 3 includes two groups of contact flaw detection components arranged below the base plate 11.

[0042] Since the track wheels 14 on the track inspection trolley 1 are only suitable for moving on railway tracks and are difficult to move normally and quickly on ordinary roads, in order to facilitate the rapid movement of the track inspection trolley 1, a plurality of groups of rollers 4 for supporting the track inspection trolley 1 to move on ordinary roads are also provided on the track inspection trolley 1. In the present embodiment, two groups of rollers 4 are provided corresponding to the track wheels 14, and each roller 4 is coaxially arranged on the corresponding rotating shaft 15, and the lower end of each roller 4 is lower than the lower end of each track wheel 14, that is, the diameter of each roller 4 is larger than the track wheel 14.

[0043] Each roller 4 can be detachably mounted on the end of the corresponding shaft 15, and the end of the shaft 15 is provided with a connecting structure 5 for mounting and dismounting the roller 4, Figure 3 , Figure 4 and Figure 5 The connecting structure 5 includes an insert rod 51 and a locking sleeve 52. The insert rod 51 is coaxially fixed on the axis of the roller 4. A slot 151 is opened at the end of the rotating shaft 15 along the length direction of the rotating shaft 15. The insert rod 51 is plugged and fitted into the slot 151. The locking sleeve 52 is sleeved and rotatably installed outside the insert rod 51.

The locking sleeve 52 can be sleeved outside the rotating shaft 15 to lock and fit the internal thread and the external thread 152.

[0045] In order to enable the insertion rod 51 to be more firmly inserted into the slot 151, the end of the insertion rod 51 is arranged to be an outer polygon, and the inner wall of the slot 151 is arranged to be an inner polygon corresponding to the end of the insertion rod 51. Specifically, the end of the insertion rod 51 is arranged to be an outer hexagon, and the inner wall of the slot 151 is arranged to be an inner hexagon correspondingly.

[0046] When the track inspection trolley 1 needs to be moved onto the railway track, or moved out of the railway track, in order to facilitate the installation of the roller 4, the track inspection trolley 1 is also provided with multiple groups of lifting mechanisms 6 for lifting the track inspection trolley 1. In the present embodiment, two groups of lifting mechanisms 6 are provided, and the two groups of lifting mechanisms 6 are respectively for the front and rear ends of the base plate 11.

[0047] Reference Figure 2 and Figure 3 The lifting mechanism 6 includes a lifting cylinder 61 and a lifting plate 62.
