Description

Technical Field

[0001] This utility model belongs to the field of auxiliary lifting technology for calibration platforms, specifically relating to a new type of lifting frame for a calibration platform of a railway track inspection instrument. Background Technology

[0002] Railway tracks require regular maintenance and inspection, typically using track inspection instruments to measure data such as track gauge and superelevation. When using track inspection instruments, they need to be periodically initialized and calibrated using a calibration platform. When checking the indication errors and repeatability of superelevation, track alignment, and elevation, the calibration platform needs to be adjusted horizontally from zero to the calibration points required by the calibration procedures using a lifting mechanism.

[0003] A search revealed that the authorized patent with publication number CN205575467U, entitled "A Lifting and Lowering Device for a Track Inspection Instrument Calibration Platform," uses an integrated installation for its driven device. However, due to its bulkiness, it requires the assistance of a lifting device during installation with the bracket, making installation difficult. Therefore, this paper provides another novel lifting frame for a railway track inspection instrument calibration platform to solve the above-mentioned technical problems. Utility Model Content

[0004] The existing lifting devices for track inspection instrument calibration platforms require the assistance of lifting equipment during installation, which is inconvenient. This invention provides a novel lifting frame for a railway track inspection instrument calibration platform, featuring a detachable connecting rod between two support pipes. During transport, the connecting bolts are unscrewed, separating the frame from the middle of the connecting rod, thus reducing the transport load. The lifting frame can be installed from both ends, significantly reducing the difficulty of installation and effectively solving the problem of inconvenience caused by the need for lifting equipment in the existing lifting devices for track inspection instrument calibration platforms. The specific technical solution is as follows:

[0005] A novel railway track inspection instrument calibration platform lifting frame includes two support shafts. Each support shaft includes a support tube, and support shaft heads are fixedly installed at both ends of the support tube. A connecting lug is fixedly installed on the outer surface of the left support shaft head. A hydraulic telescopic column is rotatably installed at the end of the connecting lug away from the support shaft head. A connecting seat is rotatably installed on the outer surface of the right support shaft head. A detachable connecting rod is installed between the two support tubes.

[0006] In the above technical solution, the connecting rod includes two connecting shafts, each of which has a plug-in end. A connecting rod is plugged in between the two inner plug-in ends, and a connecting bolt is screwed between the connecting rod and the two connecting shafts.

[0007] In the above technical solution, protrusions are inserted and installed inside the outer plug-in end. The protrusions are welded and fixed to the corresponding connecting shafts, and shaft retaining rings are fixedly installed on the outer surface of the protrusions. The shaft retaining rings are sleeved on the outer surface of the corresponding support tube.

[0008] In the above technical solution, the shaft retaining ring is welded and fixed to the corresponding support tube;

[0009] In the above technical solution, both ends of the support tube are provided with flared openings, the support shaft head is inserted and installed in the corresponding flared openings, and the support shaft head is welded and fixed to the corresponding support tube.

[0010] In the above technical solution, deep groove ball bearings are installed between the support shaft head on the right and the connecting seat, and on the outer surface of the support shaft head on the left.

[0011] The novel railway track inspection instrument calibration platform lifting frame of this utility model has the following advantages compared with the prior art:

[0012] This invention reduces the transport load by configuring a detachable connecting rod between two support pipes. During the transfer phase, the connecting bolts are unscrewed, and the rod is separated from the middle. When installing the lifting frame, installation can be carried out from both ends, greatly reducing the difficulty of the installation operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-5 This utility model provides a technical solution:

[0021] A novel railway track inspection instrument calibration platform lifting frame includes two support shafts 1. Each support shaft 1 includes a support tube 11, with support shaft heads 12 fixedly installed at both ends. A connecting lug 13 is fixedly installed on the outer surface of the left support shaft head 12. A hydraulic telescopic column 6 is rotatably installed at the end of the connecting lug 13 away from the support shaft head 12. A connecting seat 7 is rotatably installed on the outer surface of the right support shaft head 12. A detachable connecting rod is installed between the two support tubes 11. The connecting rod includes two connecting shafts 3. Both ends of the connecting shafts 3 have insertion ends 31. A connecting rod 4 is inserted between the two inner insertion ends 31. A connecting bolt 5 is screwed between the connecting rod 4 and the two connecting shafts 3. A protrusion 21 is inserted into the inner of the outer insertion end 31. The protrusion 21 is welded and fixed to the corresponding connecting shaft 3. A shaft retaining ring 2 is fixedly installed on the outer surface of the protrusion 21. The shaft retaining ring 2 is fitted onto the outer surface of the corresponding support tube 11.

[0022] During installation, first, fix the right-side support shaft 1 to the lower surface of the calibration table via the connecting seat 7. Then, insert the connecting rod 4 between the insertion ends 31 of the two connecting shafts 3. When the connecting rod 4 is fully inserted into the insertion ends 31 of the two connecting shafts 3, the inner ends of the two connecting shafts 3 will be together. At this point, use the connecting bolts 5 to fix the connecting rod 4 to the two connecting shafts 3 respectively. After that, install the two hydraulic telescopic columns 6 inside the calibration table via the external adapter. (The terminology for installing the hydraulic telescopic columns 6 using the external adapter is...) Commonly used methods within the field will not be explained in detail here. This ensures that the hydraulic telescopic column 6 can rotate adaptively during the extension and retraction process, so as to cooperate with the lifting of the support tube 11 through the connecting lug 13. During installation, the position of the left support tube 11 is adjusted so that it can support the left side of the calibration table. This ensures that, in the extended state of the hydraulic telescopic column 6, the left support tube 11 can lift the left side of the calibration table to achieve the tilt angle required during calibration. Compared with the existing technology, this lifting frame can greatly reduce the installation intensity and is more convenient and faster to install.

[0023] Specifically, the shaft retaining ring 2 is welded and fixed to the corresponding support tube 11.

[0024] To ensure the installation strength between the support shaft head 12 and the support tube 11, flared openings 111 are provided at both ends of the support tube 11. The support shaft head 12 is inserted into the corresponding flared opening 111 and welded to the corresponding support tube 11. By embedding one end of the support shaft head 12 into the support tube 11 through the flared opening 111, the strength of the two after installation can be enhanced.

[0025] Finally, deep groove ball bearings 14 are installed between the right support shaft head 12 and the connecting seat 7 and on the outer surface of the left support shaft head 12. The right deep groove ball bearing 14 is intended to realize the rotational connection between the right support shaft head 12 and the connecting seat 7; the left deep groove ball bearing 14 is used to lift the calibration table, ensuring good lifting performance of the calibration table while effectively avoiding unnecessary friction between the left support tube 11 and the calibration table.
