A guide wheel

Abstract

This invention provides a guide wheel, including a mounting bracket, a guide wheel body on the mounting bracket, a replaceable outer wheel assembly on the guide wheel body, and multiple positioning components on the guide wheel assembly. Through this structure, the guide wheel body, outer wheel assembly, and positioning components work together. The dovetail groove on the inner wheel of the guide wheel body engages with the dovetail protrusions on the multiple outer wheel bodies of the outer wheel assembly, facilitating the replacement of the damaged outer wheel body. Simultaneously, the positioning and fixing components of the positioning components, engaging with the first positioning groove of the guide wheel body and the second positioning groove of the outer wheel body respectively, allow the outer wheel body to slide on the guide wheel body, thus ensuring stable mounting of the outer wheel body on the guide wheel body.

Description

Technical Field

[0001] This utility model relates to the field of guide wheel technology, and in particular to a guide wheel. Background Technology

[0002] Tracked construction machinery is generally equipped with four wheels and one track. The four wheels refer to the drive wheel, idler wheel, load-bearing wheel, and support wheel. The track refers to the track. In existing tracked construction machinery, the idler wheel is generally located inside the front end of the track. The main function of the idler wheel is to guide the track to wind correctly and to adjust the tension of the track through the tensioning device to ensure stable operation of the equipment.

[0003] Existing idler wheels are generally manufactured using a one-piece casting method. When the idler wheel wears down due to long-term friction with the track after running for a period of time, the entire idler wheel needs to be replaced, resulting in high replacement costs.

[0035] See Figures 1 to 4 An embodiment of this utility model provides a guide wheel, including a mounting bracket 1, a guide wheel body 2 disposed on the mounting bracket 1, a replaceable outer wheel assembly 3 disposed on the guide wheel body 2, and a plurality of positioning components 4 disposed on the guide wheel body 2;

[0036] The guide wheel body 2 includes a wheel plate 21. A wheel core 22 rotatably connected to the mounting bracket 1 is provided at the axis of the wheel plate 21, and an inner wheel body 23 is provided on the surface of the wheel plate 21. The surface of the inner wheel body 23 is provided with a plurality of dovetail grooves 231. A first positioning groove 232 is provided at the position of the positioning component 4 corresponding to the dovetail groove 231. A plurality of fixing grooves 233 are provided at the bottom of the first positioning groove 232.

[0037] The outer wheel assembly 3 includes multiple arc-shaped outer wheel bodies 31, and the positioning assembly 4 is disposed between two adjacent outer wheel bodies 31. The outer wheel body 31 is provided with multiple dovetail protrusions 311 that cooperate with the dovetail grooves 231 at the corresponding positions. The two ends of the outer wheel body 31 are respectively provided with concave second positioning grooves 312 corresponding to the positions of the positioning assembly 4.

[0038] The positioning component 4 includes a positioning member 41 and a plurality of fixing members 42 adapted to the fixing groove 233. The positioning member 41 is adapted to the first positioning groove 232 and the second positioning groove 312. The positioning member 41 has a positioning hole 411 through it at the position corresponding to the fixing groove 233. The positioning member 41 is fixed to the inner wheel body 23 by the fixing members 42, so that the positioning member 41 passes through the positioning hole 411 and the fixing groove 233 in sequence.

[0039] With the above structure, the guide wheel body 2, the outer wheel assembly 3, and the positioning assembly 4 cooperate to facilitate the replacement of the damaged outer wheel body 31 by means of the dovetail groove 231 on the inner wheel body 23 of the guide wheel body 2 and the dovetail protrusions 311 on the multiple outer wheel bodies 31 of the outer wheel assembly 3. At the same time, the positioning member 41 and the fixing member 42 of the positioning assembly 4 cooperate with the first positioning groove 232 of the guide wheel body 2 and the second positioning groove 312 of the outer wheel body 31, respectively, to enable the outer wheel body 31 to slide on the guide wheel body 2, thereby allowing the outer wheel body 31 to be stably installed on the guide wheel body 2.

[0040] In one embodiment, see Figures 2 to 5 The side of the positioning component 41 facing the outer wheel body 31 is a continuous curved surface structure 413, and the sidewalls of the first positioning groove 232 and the second positioning groove 312 are adapted to the continuous curved surface structure 413. In practical applications, the cooperation between the continuous curved surface structure 413 of the positioning component 41 and the first positioning groove 232 and the second positioning groove 312 can make the lateral force on each position of the positioning component 41 uniform, thereby improving the service life of the positioning component 41 and the positioning effect of the positioning component 41.

[0041] In one embodiment, see Figure 3 and Figure 5 The fixing member 42 is a bolt, with one end being a bolt head 421. Both the positioning hole 411 and the fixing groove 233 are threaded holes. The positioning member 41 has a recessed groove 412 corresponding to the position of the bolt head 421, and the bolt head 421 fits into the groove 412. In practical applications, the positioning member 41 can be fixed to the inner wheel body 23 by the bolt of the fixing member 42 engaging with the threaded holes of the positioning hole 411 and the fixing groove 233 respectively.

[0042] The outer surface of the outer wheel body 31 is provided with a raised limiting ring 313, and the positioning member 41 is provided with a raised mating protrusion 414 at the position corresponding to the limiting ring 313. The mating protrusion 414 is adapted to the limiting ring 313 between adjacent outer wheel bodies 31. In actual use, the limiting ring 313 and the mating protrusion 414 cooperate with the track and limit the track movement.

[0043] In one embodiment, see Figure 2 Along the circumference of the wheel plate 21, multiple weight-reducing holes 24 are provided. In practical applications, the overall weight of the guide wheel can be reduced by the presence of these weight-reducing holes 24.

[0044] Multiple reinforcing spokes 25 are provided on both sides of the wheel plate 21. The reinforcing spokes 25 are located between two adjacent weight-reducing holes 24. One end of the reinforcing spokes 25 is connected to the wheel core 22, and the other end is connected to the inner wheel body 23. In practical applications, the strength of the wheel plate 21 can be improved by setting the reinforcing spokes 25.
