The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0052] As Figure 1-8 shown, in this embodiment, a portable rail car is provided, including a first frame assembly 11 and a second frame assembly 12. Fixed rods 111 are provided on both the first frame assembly 11 and the second frame assembly 12, and connecting components 13 are provided at both ends of the fixed rods 111.

[0053] At the same time, a swing rod 14 is provided corresponding to the connecting component 13. In this embodiment, two swing rods 14 are provided. In the installed state, the fixed rods 111 on the first frame assembly 11 and the second frame assembly 12 are arranged oppositely, the two swing rods 14 are arranged oppositely, and the fixed rods 111 and the swing rods 14 are arranged at intervals and connected in sequence to form a load-bearing frame 10.

[0054] As a preferred solution, in this embodiment, both ends of the two swing rods 14 are detachably connected to the connecting components 13 on the first frame assembly 11 and the second frame assembly 12 respectively.

[0055] As an application example, when being stored, the two swing rods 14 can be detached from the connection assembly 13. At this time, the fixed rod 111 is also in a relatively independent state, so that the fixed rod 111 and the swing rods 14 can be centrally collected and stored. Compared with the situation in the prior art where the track trolley needs to be stored in a whole vehicle state, the space required for storage is greatly reduced. When in use, the fixed rod 111 and the swing rods 14 in the stored state can be first moved to the target position, and then the load-bearing frame 10 can be assembled, so as to realize the convenient movement and assembled use of the track trolley, and the operation efficiency can be effectively improved.

[0056] Further, the connection assembly 13 includes a limit plate 131 and a protective layer plate 132. The provided limit plate 131 can serve as an installation carrier for installing the fixed rod 111 and the swing rods 14; and the provided protective layer plate 132 can facilitate the extension of the service life of the track trolley.

[0057] As a preferred solution, the limit plate 131 is bent to form an inner groove 1311. In the installed state, the notch of the inner groove 1311 faces the horizontal direction, and the opposite side walls of the inner groove 1311 in the horizontal direction are open structures.

[0058] The end of the fixed rod 111 extends relatively vertically into the inner groove 1311. At this time, a swing space for the swing rod 14 to swing is formed between the inner side of the fixed rod 111 and the bottom wall of the inner groove 1311. By providing the swing space, the swing amplitude of the swing rod 14 can be limited to a certain extent, so as to facilitate the connection and fixation of the load-bearing frame 10. For example, in this embodiment, the fixed rod 111 and the bottom wall of the inner groove 1311 are perpendicular to each other. Therefore, when the swing rod 14 swings to abut against the bottom wall of the inner groove 1311, the swing rod 14 is perpendicular to the fixed rod 111 at this time, so as to facilitate the loading of the load-bearing frame 10.

[0059] As a preferred solution, a first bolt member 1312 is provided on the limiting plate 131. The first bolt member 1312 passes through the upper groove wall of the inner groove 1311 and is threadedly connected to the swing rod 14. During use, the first bolt member 1312 can be rotated so that the first bolt member 1312 and the swing rod 14 are in a relatively loose state. At this time, the connection restriction at the other end of the swing rod 14 is released, and the swing rod 14 can swing around the first bolt member 1312; when the carrying frame 10 needs to be carried, the swing rod 14 can be swung relative to the fixed rod 111 to a certain state at this time. For example, when the fixed rod 111 and the swing rod 14 are perpendicular to each other as shown in the example of this application, the first bolt member 1312 can be tightened at this time to fix the swing rod 14, and the operation is simpler and more convenient.

[0060] As another application example, during storage, only one end of the swing rod 14 can be detached, while the connection state of the other end of the swing rod 14 is retained; at this time, under the action of the first bolt member 1312, the swing rod 14 can be swung towards the fixed rod 111 until they overlap. At this time, on the basis of realizing storage, the disassembly operation can be further simplified, and the disassembly and assembly of the carrying frame 10 can be more convenient and the operation efficiency is higher.

[0061] As a preferred solution, in this embodiment, a plug member 1313 is also detachably provided on the limiting plate 131. The plug member 1313 can also pass through the upper groove wall of the inner groove 1311 and then be inserted and connected to the swing rod 14. A jack for inserting the plug member 1313 is provided on the swing rod 14. By providing the plug member 1313, the current state of the swing rod 14 can be further restricted, avoiding the loosening of the first bolt member 1313 during long-term use, which may cause a change in the relative position state between the swing rod 14 and the fixed rod 111; at the same time, the force transmission between the fixed rod 111 and the swing rod 14 can be more concentrated at the plug member 1313, avoiding the situation that the first bolt member 1312 is in a long-term stressed state, resulting in a reduction or even failure of the installation and fixing effect, making the structure of the formed carrying frame 10 more stable and reliable, and facilitating the extension of the service life of the device.

[0062] As an application example, when the swing rod 14 and the fixed rod 111 are in an overlapping storage state, the plug member 1313 passes through the swing rod 14 and is inserted into the protective layer plate 132 to restrict the swing of the swing rod 14 in the overlapping state for storage.

[0063] Further, in this embodiment, four track wheels 15 are provided below the bearing frame 10. The track wheels 15 are connected to the limiting plates 131 in a one-to-one correspondence and are located below the limiting plates 131. As a preferred solution, the mounting brackets of the track wheels 15 are connected to the lower groove wall of the inner groove 1311 by fasteners such as bolts.

[0064] Furthermore, a positioning structure is provided between one side of the protective layer plate 132 and the bottom wall of the inner groove 1311. By means of this positioning structure, quick alignment and installation between the protective layer plate 132 and the limiting plate 131 can be achieved.

[0065] As a preferred solution, in this embodiment, the positioning structure includes a plurality of protrusions 1321 provided on the protective layer plate 132 and limiting holes 1314 provided on the bottom wall of the inner groove 1311 to match the protrusions 1321. The protrusions 1321 are inserted and connected to the limiting holes 1314.

[0066] As a preferred solution, the remaining sides of the protective layer plate 132 are bent towards the lower groove wall of the inner groove 1311, so that an air layer is formed between the protective layer plate 132 and the lower groove wall of the inner groove 1311. At this time, the fasteners for fixing the track wheels 15 can be arranged in the air layer, thereby improving the protection degree of the relevant fasteners and prolonging the service life of the device.

[0067] In addition, a reinforcing rod 16 and a plurality of second bolt members 161 are provided in this embodiment. In the installed state, the reinforcing rod 16 is arranged inside the bearing frame 10, and a plurality of the second bolt members 161 penetrate from the outside of the relatively arranged fixing rods 111 or the swing rods 14 and are connected to the reinforcing rod 16. The provided reinforcing rod 16 can further improve the overall stress performance of the formed bearing frame 10.

[0068] As an application example, in this embodiment, the reinforcing rod 16 is arranged parallel to the two relatively arranged fixing rods 111. At this time, the reinforcing rod 16 and the fixing rods 111 form a parallel rod group; in some other application examples, the reinforcing rod 16 can also be arranged parallel to the two relatively arranged swing rods 14. At this time, the reinforcing rod 16 and the swing rods 14 form a parallel rod group.

[0069] As a preferred solution, connecting buckles 162 are provided at both ends of the reinforcing rod 16. At this time, the connecting buckles 162 are snap-connected to the swing rod 14. As an application example, in this embodiment, the fixing rod 111 and the swing rod 14 are both rectangular rod structures, and the connecting buckles 162 are arranged on the upper end surface of the swing rod 14. The provided connecting buckles 162 can make the force at the connection between the reinforcing rod 16 and the swing rod 14 more concentrated at the connection between the connecting buckles 162 and the swing rod 14 under the load state, thereby reducing the connection force between the second bolt member 161 and the swing rod 14 and the reinforcing rod 16.

[0070] As a preferred solution, in this embodiment, a plurality of strip holes 101 for installing external devices are provided on the parallel rod group. For example, the strip holes 101 are provided on both the reinforcing rod 16 and the fixing rod 111, and the length direction of the strip holes 101 is perpendicular to the advancing direction of the carrying frame 10. By providing the strip holes 101, it is convenient for the installation and use of external devices on the formed carrying frame 10, and at the same time, the position adjustment of the external devices relative to the carrying frame 10 can be realized.

[0071] Furthermore, in this embodiment, a clamping assembly 17 is also provided corresponding to the strip holes 101. The clamping assembly 17 includes an upper clamping block 171, a lower clamping block 172, and a third bolt member 173. Among them, clamping portions are provided on the upper clamping block 171 and the lower clamping block 172. The clamping portion of the upper clamping block 171 and the clamping portion of the lower clamping block 172 are arranged opposite to each other and form a space for the rod bodies of the reinforcing rod 16 and the fixing rod 111 to pass through. The third bolt member 173 passes through the lower clamping block 172 and the strip hole 101 and then is connected to the upper clamping block 171, and the external device is installed on the upper clamping block 171. By providing the clamping assembly 17, the force at the connection between the external device and the carrying frame 10 can be made more stable and reliable.

[0072] As a preferred solution, the first bolt member 1312, the second bolt member 161, and the third bolt member 173 in this embodiment all adopt plum blossom handle bolts to facilitate the convenient assembly of operators on site.

[0073] As an application example, the external device in this embodiment can be set as the support frame assembly 2, and the support frame assembly 2 includes a main support rod 21 and a plurality of auxiliary support rods 22. Among them, the main support rod 21 can be set to be composed of a plurality of rod bodies sleeved together. At this time, by using fasteners to fix and adjust the rod bodies between the sleeves, the length adjustment of the main support rod 21 in the vertical height can be achieved. One end of each of the plurality of auxiliary support rods 22 is hinged to the main support rod 21. During installation and use, the bottoms of the main support rod 21 and the auxiliary support rods 22 are respectively arranged on the upper clamping block 171.

[0074] In an intelligent rail transportation system, it is necessary to detect and calibrate the relative distance between the locomotive and the tank car. In the traditional technology, a reflector 3 is manually held in cooperation with a laser rangefinder for detection. However, the reflector 3 is relatively heavy, and the detection position is relatively high. Manual holding for detection has the problems of difficult control of detection accuracy and easy fatigue. By using the rail trolley provided in this embodiment, by arranging the support frame assembly 2 on the rail trolley and fixing the reflector 3 on the support frame assembly 2, the reciprocating position adjustment can be completed by the rail trolley. Through the setting of the strip-shaped hole 101, the position calibration adjustment of the support frame assembly 2 relative to the rail trolley can also be realized, and the operation can be simpler and more convenient. The rail trolley provided in this embodiment can be conveniently carried on-site, so that it can be well applied to the detection and calibration operation of the intelligent rail transportation system.
