Description

Technical Field

[0001] This utility model relates to the field of railway construction, and in particular to a rail transport device. Background Technology

[0002] In railway construction, rails need to be moved. Existing technology usually involves welding or fixing two bearing seats to a steel base plate, and installing a rotating shaft between the two bearing seats. By placing the rails on the rotating shaft and pushing them, the rotating shaft is passively rotated to bear the load, thus realizing the rail movement. However, after long-term use, the rotating shaft and bearing seats will be damaged due to wear, and it is inconvenient to replace the rotating shaft and bearings after damage. Utility Model Content

[0003] The purpose of this invention is to solve the problems mentioned in the background art by designing a rail transport device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a rail transport device, comprising a mounting base, an inner mounting part, an outer mounting part, an inner limiting groove, an outer limiting groove, bearing seats, mounting feet, a bearing shaft, and a bearing position locking structure. The mounting base has an inner mounting part and an outer mounting part on both sides. The inner mounting part has an inner limiting groove, and the outer mounting part has an outer limiting groove corresponding to the size of the inner limiting groove. The inner limiting groove does not penetrate the mounting base from the inside out, while the outer limiting groove penetrates the mounting base from the inside out. Two bearing seats are respectively located on both sides of the mounting base. Mounting feet are provided on both sides of the lower part of the bearing seats. The mounting feet on the two bearing seats are respectively located within the inner and outer limiting grooves on both sides. A bearing shaft is installed between the two bearing seats. The outer mounting part has a bearing position locking structure.

[0005] Furthermore, the bearing shaft is provided with a retaining ring, which is located inside the bearing housing.

[0006] Furthermore, limit rings are respectively fitted on both sides of the bearing shaft, with the inner end of the limit ring contacting the retaining ring and the outer end of the limit ring contacting the inner ring of the bearing housing.

[0007] Furthermore, the diameter of the limiting ring is larger than the bearing diameter of the bearing housing.

[0008] Furthermore, the bearing position locking structure includes a locking block, an insertion hole, a fixed threaded hole, and a fixed screw. The locking block is inserted into the outer limiting groove, the locking block has an insertion hole, the mounting base below the insertion hole has a fixed threaded hole, and a fixed screw is inserted through the insertion hole and engaged with the fixed threaded hole.

[0009] Beneficial effects: This utility model provides a rail transport device with the following advantages: Through its structural design, the device installs a bearing shaft between two bearing seats, and then inserts the two bearing seats into the inner and outer limiting grooves on the inner and outer mounting parts, respectively. The bearing seat position is locked in the outer limiting groove using a bearing position locking structure. Combined with the cooperation of the mounting foot, the inner limiting groove, and the outer limiting groove, the position of the mounting foot is restricted, thereby realizing the installation. When it is necessary to replace the bearing seat or the bearing shaft, it is only necessary to release the locking of the bearing position locking structure to remove the bearing seat, which facilitates the replacement of the bearing seat and the bearing shaft.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "set / set up," "sleeve," "connection," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a rail transport device, including a mounting base 1, an inner mounting part 2, an outer mounting part 3, an inner limiting groove 4, an outer limiting groove 5, a bearing seat 6, mounting feet 7, a bearing shaft 8, and a bearing position locking structure. The mounting base 1 is provided with an inner mounting part 2 and an outer mounting part 3 on both sides respectively. The inner mounting part 2 has an inner limiting groove 4, and the outer mounting part 3 has an outer limiting groove 5 corresponding to the size of the inner limiting groove 4. The inner limiting groove 4 does not penetrate the mounting base 1 from the inside to the outside, while the outer limiting groove 5 penetrates the mounting base 1 from the inside to the outside. Two bearing seats 6 are respectively provided on both sides of the mounting base 1. Mounting feet 7 are provided on both sides of the lower part of the bearing seats 6. The mounting feet 7 on the two bearing seats 6 are respectively located in the inner limiting groove 4 and the outer limiting groove 5 on both sides. A bearing shaft 8 is installed between the two bearing seats 6. The outer mounting part 3 is provided with a bearing position locking structure.

[0016] In this utility model, the bearing shaft 8 is provided with a retaining ring 9. The retaining ring 9 on the bearing shaft 8 is located inside the bearing seat 6, and the retaining ring 9 plays a role in limiting the position of the bearing shaft 8 on the bearing seat 6.

[0017] In this utility model, limit rings 10 are respectively fitted on both sides of the bearing shaft 8. The inner end of the limit ring 10 contacts the retaining ring 9, and the outer side of the limit ring 10 contacts the inner ring of the bearing in the bearing seat 6. The limit rings 10 play a role in limiting the track, and the sliding limit rings 10 are easy to replace.

[0018] In this invention, the diameter of the limiting ring 10 is larger than the bearing diameter of the bearing seat 6. The fact that the diameter of the limiting ring 10 is larger than the diameter of the bearing seat 6 can, to a certain extent, protect the bearing seat 6 and reduce the possibility of the rail hitting the bearing seat 6.

[0019] In this utility model, the bearing position locking structure includes a locking block 11, an insertion hole 12, a fixing threaded hole 13, and a fixing screw 14. The locking block 11 is inserted into the outer limiting groove 5. The locking block 11 has an insertion hole 12. The mounting base 1 below the insertion hole 12 has a fixing threaded hole 13. The fixing screw 14 is inserted through the insertion hole 12 and engaged with the fixing threaded hole 13. By inserting the locking block 11 into the outer limiting groove 5, and then using the fixing screw 14 in conjunction with the insertion hole 12 and the threaded hole 13, the position of the locking block 11 is locked, thereby locking the position of the bearing seat 6.

[0020] In this implementation plan: In use, the bearing shaft 8 is installed between the two bearing seats 6, and then the two bearing seats 6 are respectively inserted into the inner limiting groove 4 and the outer limiting groove 5 on the inner mounting part 2 and the outer mounting part 3. Then, the bearing seat 6 is locked in the position by the bearing position locking structure in the outer limiting groove 5. Combined with the cooperation of the mounting foot 7, the inner limiting groove 4 and the outer limiting groove 5, the position of the mounting foot 7 is restricted, thereby realizing the installation. When it is necessary to replace the bearing seat 6 or the bearing shaft 8, it is only necessary to release the locking of the bearing position locking structure to remove the bearing seat 6, which facilitates the replacement of the bearing seat 6 and the bearing shaft 8.
