Description
Technical Field
[0001] This utility model belongs to the technical field of rail welding production line equipment, specifically, it relates to an adjustable guide device for a rail welding production roller conveyor. Background Technology
[0002] The current rail welding production line track consists of active rails, passive rails, and guide wheels.
[0003] The guide wheels are fixed to the track line by bolts. This connection method has significant shortcomings in actual production adjustments: when the operation requires adjusting the position of the guide wheel assembly towards the center (inward) or outward of the track, the operator must first loosen the fixing bolts, then manually adjust and position it based on experience, and finally retighten the bolts. This process is not only cumbersome and time-consuming, significantly reducing adjustment efficiency, but also increases the operator's workload and work pressure, becoming a bottleneck restricting the flexibility of the production line.
[0004] More importantly, during the manual adjustment of the guide wheels, the support brackets that mount the guide wheels are highly susceptible to unexpected lateral shifts. This shift directly disrupts the relative position of the left and right guide wheel sets, causing the axes of the two sets of guide wheels to lose parallelism. The serious consequences of this misalignment are twofold: firstly, it directly affects the precise alignment of the rail welding end faces, easily causing welding position deviations and impacting welding quality; secondly, this abnormal stress state significantly accelerates the abnormal wear of the guide wheels and related transmission components, directly affecting the equipment's service life and stability.
[0005] In view of this, this utility model is proposed. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0030] Example 1: An adjustable guide device for a steel rail welding production roller conveyor, specifically as follows: Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the system includes a fixed base 10, which is rectangular and placed on the ground; and an adjustment structure, comprising a first adjustment part and a second adjustment part. The first adjustment part includes two sets of first fixing plates 14 fixedly installed on the top of the fixed base 10. The first fixing plates 14 have first threaded grooves 15 inside, and a first threaded rod 16 is screwed into the first threaded grooves 15. Two sets of guide wheel brackets 19 are provided on the top of the fixed base 10. Holes are formed on one outer wall of each guide wheel bracket 19, and a first limiting circular plate 17 is fixedly installed inside the hole within the guide wheel bracket 19. One end of the first threaded rod 16 is rotatably installed inside the first limiting circular plate 17. The second adjustment part also includes a knob 18 fixedly installed on the other end of the first threaded rod 16. The guide wheels can be quickly adjusted using the adjustment structure. Rotating the knob 18 causes the first threaded rod 16 to rotate inside the first limiting circular plate 17, which in turn rotates the first threaded rod 16 inside the first threaded groove 15, pushing the first limiting circular plate 17 to move, and thus moving the guide wheel brackets 19.
[0031] Based on the above, the structure of the fixed base 10, the first fixed plate 14, the first threaded groove 15, the first threaded rod 16, the first limiting circular plate 17, the knob 18, and the guide wheel bracket 19 achieves the purpose of quickly adjusting the guide wheel. The track gauge of the guide wheel can be changed at any time through manual adjustment to complete the guiding function of the entire track line, improve the efficiency of rail track line adjustment, save manpower, and complete the adjustment of the guide wheel conveniently and efficiently, thereby improving the ease of use of the device.
[0032] Example 2: Based on Example 1, specifically as follows... Figure 1 , Figure 4 and Figure 5 As shown, the bottom of the guide wheel bracket 19 has a first limiting hole 21, and a second fixing rod 30 is provided inside the first limiting hole 21.

The second fixing rod 30 is placed inside the first limiting hole 21.
[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the bottom of the fixed base 10 has two sets of first sliding grooves 12, and the inside of the first sliding grooves 12 has two sets of second sliding grooves 13.

The inside of the second slider 27 has a second threaded groove 28. The first slider 26 is placed inside the first sliding groove 12, and the second slider 27 is placed inside the first sliding groove 12.
[0034] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the second threaded rod 31 is helically installed inside the second threaded groove 28. The bottom of the first limiting plate 29 is in close contact with the inner bottom of the guide wheel bracket 19, and the top of the second threaded groove 28 is in close contact with the bottom of the guide wheel bracket 19. By rotating the first limiting plate 29, the second threaded rod 31 is helically installed inside the second threaded groove 28, so that the bottom of the first limiting plate 29 is in close contact with the inner bottom of the guide wheel bracket 19, and the top of the second threaded groove 28 is in close contact with the bottom of the guide wheel bracket 19. This positions the second fixing rod 30 and the second slider 27 between the fixed base 10 and the guide wheel bracket 19.
[0035] Based on the above, the structure of the first sliding groove 12, the second sliding groove 13, the first limiting hole 21, the first slider 26, the second slider 27, the second threaded groove 282, the first limiting plate 29, the second fixing rod 30, and the second threaded rod 31 achieves the purpose of limiting the bracket to be installed on the fixed base 10, enabling quick connection of the device, providing auxiliary limiting for the bracket, improving the stability of the bracket during movement, improving the smoothness of the bracket movement, reducing the deviation of the guide wheel, and improving the safety of the device.
[0036] Example 3: Based on Examples 1 and 2, specifically as follows... Figure 1 , Figure 2 and Figure 5 As shown, a second limiting groove 25 is provided on the inner bottom of the guide wheel bracket 19, and a first limiting groove 20 is provided on the inner top of the guide wheel bracket 19. A first fixing rod 22 is provided between the first limiting groove 20 and the second limiting groove 25. The first fixing rod 22 is installed between the second limiting groove 25 and the first limiting groove 20.
[0037] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, a guide wheel 24 is rotatably mounted on the outer wall of the first fixed rod 22, and a second limiting circular plate 23 is fixedly mounted on the top of the first fixed rod 22. The bottom of the second limiting circular plate 23 is in close contact with the top of the guide wheel bracket 19. The first fixed rod 22 is confined inside the guide wheel bracket 19 by the second limiting circular plate 23, and the guide wheel 24 guides the rail.
[0038] Specifically, such as Figure 1 As shown, the bottom of the fixed base 10 is provided with a first positioning hole 11, which is located between two sets of second sliding grooves 13. The fixed base 10 is positioned through the first positioning hole 11.
[0039] In summary, the structure of the fixed base 10, the first positioning hole 11, the guide wheel bracket 19, the first limiting groove 20, the first fixing rod 22, the second limiting circular plate 23, the guide wheel 24, and the second limiting groove 25 achieves the purpose of limiting the installation of the guide wheel, simplifies the installation steps of the device, improves the installation strength of the guide wheel, and optimizes the user experience of the device.
[0040] Working principle: The fixed base 10 serves as the foundation of the device, placed rectangularly on the ground. It is positioned by engaging with pre-embedded parts or bolts in the ground via the first positioning hole 11 at the bottom, preventing base displacement during adjustment. Rotating the knob 18 causes the first threaded rod 16 to rotate within the first threaded groove 15 of the first fixed plate 14. One end of the first threaded rod 16 is rotatably mounted on the first limiting circular plate 17. During rotation, it pushes the first limiting circular plate 17 to move laterally, thereby driving the guide wheel bracket 19 to slide laterally. The two sets of first threaded rods 16 can rotate independently, allowing the guide wheel brackets 19 on both sides to move synchronously inward or outward, quickly adjusting the track gauge. The top of the fixed base 10 has a first sliding groove 12, with a second sliding groove 13 nested inside. The first slider 26 is slidably mounted in the first sliding groove 12, and its top second slider 27 is slidably mounted in the second sliding groove 13, forming a double longitudinal limit to prevent longitudinal movement during bracket adjustment. The bottom of the guide wheel bracket 19 has a first limiting hole 21, into which a second fixed rod 30 is inserted. The second threaded rod 31 is screwed into the second threaded groove 21 of the second slider 27. 8. By rotating and tightening the first limiting plate 29, the bottom of the first limiting plate 29 is tightly attached to the bottom inner side of the bracket, and the top of the second slider 27 is tightly attached to the bottom of the bracket, thus achieving longitudinal fixation of the bracket. The two ends of the first fixing rod 22 are respectively embedded in the first limiting groove 20 and the second limiting groove 25 inside the guide wheel bracket 19 to achieve axial positioning. The guide wheel 24 is rotatably installed on the outer wall of the first fixing rod 22, and its outer circumference contacts the side of the rail to achieve lateral guidance. The second limiting circular plate 23 is installed on the top of the first fixing rod 22, and its bottom is tightly attached to the top of the bracket. To prevent the fixing rod from falling off longitudinally during adjustment, rotate the knobs 18 on both sides to drive the guide wheel bracket 19 to move laterally to the target track gauge via the first threaded rod 16. Insert the second fixing rod 30 into the first limiting hole 21, rotate the first limiting plate 29 to screw the second threaded rod 31 into the second threaded groove 28, lock the longitudinal position of the bracket, embed the first fixing rod 22 into the limiting groove, install the guide wheel 24, and fix it with the second limiting round plate 23. Confirm the position of the base through the first positioning hole 11 to ensure that the entire device is aligned with the roller conveyor line.
