Description

Technical Field

[0001] This utility model relates to the field of excavator guide wheel technology, specifically an excavator guide wheel with an anti-deviation calibration structure. Background Technology

[0002] An excavator is a heavy-duty engineering machine used to excavate materials such as soil, coal, and silt. It uses its bucket to dig materials above or below the machine's surface and load them into transport vehicles or unload them into stockpiles. When an excavator turns, it does so through the combined action of the drive wheels, guide wheels, track rollers, carrier rollers, and tracks, with the guide wheels playing a particularly crucial role.

[0003] In existing technology, when a typical guide wheel rotates, it may deviate from the track, thus affecting its steering performance. Furthermore, when the excavator is working, a large amount of dust and dirt will adhere to the grooves of the guide wheel, increasing its weight. If it is not cleaned, it will affect the performance of the guide wheel. Utility Model Content

A guide shaft is provided at the center of the guide wheel via a bearing. Both outer sides of the guide wheel are provided with annular moving grooves, and annular limiting plates are provided within the annular moving grooves. Annular calibration blocks are provided above the annular moving grooves on the inner side of the limiting plates. Screw grooves are evenly distributed within the limiting plates, and a screw is provided at the center of each screw groove. Threaded blocks are threadedly connected to the screw, and connecting blocks are evenly distributed along the bottom edge of each threaded block. Corresponding threaded sleeves are provided at the bottom of each connecting block. Annular grooves are provided on both sides of the guide wheel, and the guide wheel is positioned near... The annular limiting plate has uniformly spaced slots on one side, and bearing sleeves are provided on the guide shafts on both sides of the guide wheel. Connecting plates are uniformly spaced on the outer side of the bearing sleeves, and the other end of each connecting plate is connected to the inner side of the annular slot of the guide wheel. Rotating shafts are provided between the opposite slots of the connecting plates through bearing seats, allowing the annular limiting plate to move and align with the appropriate insertion hole. Then, the lead screw can drive the threaded block to move downward, and the threaded block can drive the threaded sleeve to move through the connecting block two and insert it into the insertion hole. This can limit and fix the annular limiting plate, facilitating the limit calibration of the track. When the guide wheel rotates, the rotating shafts between the connecting plates can rotate and clean the inner wall of the slots through the force generated by the rotation, preventing excessive dust and dirt from adhering to the slots and affecting their performance.

[0006] Preferably, springs are evenly provided on the side of the annular moving groove away from the annular calibration block, and the other end of each spring is connected to an annular limiting plate, so that the annular limiting plate can move under the extension and contraction of the spring, which facilitates the adjustment of the distance between the annular calibration blocks.

[0007] Preferably, a sliding groove is provided at the middle position of both sides of the inner wall of the screw groove, and a connecting block is slidably connected in each sliding groove. The other end of each connecting block is connected to the corresponding threaded block, so that the connecting blocks on both sides of the threaded block can move in the sliding groove, making the threaded block move more smoothly and stably.

[0008] Preferably, the guide wheels inside the annular moving groove are all uniformly provided with insertion holes, and the diameter of each insertion hole is larger than that of the threaded sleeve. The threaded sleeves outside the insertion holes are all connected to nuts by threads, so that the threaded sleeves can be inserted into the insertion holes and the nuts can be screwed onto the threaded sleeves for easy positioning and fixing.

[0009] Preferably, the outer side of the rotating shaft is uniformly provided with bristles, and the bristles of the rotating shaft are all in contact with the inner wall of the corresponding hole groove, so that the bristles clean the inner wall of the hole groove and reduce the adhesion of dust on the inner wall.

[0010] Preferably, the top end of each lead screw is provided as an optical axis, and each optical axis of the lead screw is provided with a gear II.

[0011] Preferably, a miniature turntable is provided on the outer side of the annular limiting plate at the position above the second gear, and the rotating rod on the inner side of the miniature turntable extends through the bearing to the lead screw groove where the first gear is provided, and the first gear and the second gear mesh with each other.

[0012] Preferably, a track is provided at the middle position of the outer side of the guide wheel, and a track is provided on the outer side of the track.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This excavator guide wheel with anti-deviation calibration structure, by moving the annular limiting plate and aligning it with the appropriate insertion hole, can rotate the micro turntable to drive the gear one on the rotating rod to rotate. Gear one drives the gear two meshing with it to rotate, gear two drives the lead screw to rotate, and the lead screw drives the threaded block to move downward, so that the threaded block drives the threaded sleeve to move through the connecting block two and can be inserted into the insertion hole. It can limit and fix the annular limiting plate, which is convenient for limiting and calibrating the track. Moreover, when the guide wheel rotates, the bearing sleeve can drive the rotating shaft between the connecting plates to rotate, so that it rotates through the force generated by the rotation, thereby driving the bristles to rotate and clean the groove. This can reduce the adhesion of dust and dirt in the groove, prevent excessive dust and dirt from adhering, increase the weight of the guide wheel, and affect its use effect.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-5 An embodiment of this utility model is provided: a guide wheel for excavators with an anti-deviation calibration structure, including a guide wheel 1 and a guide shaft 2. The guide shaft 2 is provided in the middle position of the guide wheel 1 through a bearing, and an annular moving groove 24 is provided on both outer sides of the guide wheel 1. An annular limiting plate 6 is provided in the annular moving groove 24, and an annular calibration block 15 is provided above the annular moving groove 24 on the inner side of the annular limiting plate 6.

[0022] When in use, the annular limiting plate 6 and the annular calibration block 15 can limit the track 8 to prevent the track 8 from deviating and affecting the excavator's steering.

[0023] Furthermore, the annular limiting plate 6 is uniformly provided with screw grooves 16, and screw 13 is provided in the middle of each screw groove 16. Threaded blocks 18 are connected to the screw 13 by threads, and connecting blocks 22 are uniformly provided on the bottom edge of the threaded blocks 18. The bottom of each connecting block 22 is provided with a corresponding threaded sleeve 20. The top of each screw 13 is provided with an optical axis, and gear 22 is provided on the optical axis of each screw 13. A miniature turntable 3 is provided on the outer side of the annular limiting plate 6 above the gear 22, and the rotating rod inside the miniature turntable 3 extends through a bearing into the screw groove 16 where a gear 11 is provided. Gear 11 and gear 22 mesh with each other.

[0024] In use, the miniature turntable 3 can be rotated to drive the gear 11 on the rotating rod to rotate. The gear 11 drives the gear 212 that meshes with it to rotate. The gear 212 drives the lead screw 13 to rotate. The lead screw 13 drives the threaded block 18 to move downward, so that the threaded block 18 drives the threaded sleeve 20 to move through the connecting block 22 and can be inserted into the insertion hole 21. This can limit and fix the annular limiting plate 6, and facilitate the limit calibration of the track 8.

[0025] Both sides of the guide wheel 1 are provided with annular grooves, and the guide wheel 1 is provided with evenly distributed holes and grooves 4 on the side near the annular limiting plate 6. Both sides of the guide shaft 2 are provided with bearing sleeves 9. The outer side of the bearing sleeves 9 is provided with evenly distributed connecting plates 5. The other end of the connecting plates 5 is connected to the inner side of the annular groove of the guide wheel 1. The holes and grooves 4 opposite to each other of the connecting plates 5 are provided with rotating shafts 10 through bearing seats. The outer side of the rotating shafts 10 is provided with evenly distributed bristles, and the bristles of the rotating shafts 10 are all in contact with the inner wall of the corresponding holes and grooves 4.

[0026] When in use, the guide wheel 1 rotates, which can drive the bearing sleeve 9 to rotate. The bearing sleeve 9 can drive the connecting plate 5 to rotate together, which can cause the rotating shaft 10 between the inner sides of the connecting plate 5 to rotate. The rotating shaft 10 rotates by the force generated by the rotation, thereby causing the brush bristles to rotate and clean the slot 4. This can reduce the adhesion of dust and dirt in the slot 4, prevent excessive dust and dirt from adhering, increase the weight of the guide wheel 1, and affect its performance.

[0027] Springs 23 are evenly arranged in the annular moving groove 24 on the side away from the annular calibration block 15, and the other end of each spring 23 is connected to the annular limiting plate 6.

[0028] In use, the outer side of the annular limiting plate 6 can be connected to the annular moving groove 24 through the spring 23, so that the extension and retraction of the spring 23 can move the annular limiting plate 6 to align it with the corresponding insertion hole 21, making it convenient to adjust the distance between the annular calibration blocks 15.

[0029] The middle position of both sides of the inner wall of the screw groove 16 is provided with a sliding groove 14, and a connecting block 17 is slidably connected in the sliding groove 14, and the other end of the connecting block 17 is connected to the corresponding threaded block 18.

[0030] When in use, the connecting blocks 17 on both sides of the threaded block 18 can move within the slide groove 14, making the threaded block 18 move more smoothly and stably.

[0031] The guide wheels 1 inside the annular moving groove 24 are all uniformly provided with insertion holes 21, and the diameter of the insertion holes 21 is larger than that of the threaded sleeve 20. The threaded sleeve 20 outside the insertion holes 21 is connected to the nuts 19 by threads.

[0032] In use, the threaded sleeve 20 can be moved downward and inserted into the corresponding insertion hole 21. Then, the nut 19 can be screwed onto the threaded sleeve 20 outside the insertion hole 21 to limit and fix it, which is convenient for limiting and fixing the annular limiting plate 6.

[0033] A track 8 is provided at the middle position of the outer side of the guide wheel 1, and a track 7 is provided on the outer side of the track 8;

[0034] When in use, the guide wheel 1 can drive the track 7 on the track 8 to rotate and turn, making it convenient for the excavator to turn.

[0035] In this embodiment, the operator moves the movable annular limiting plate 6 to align with the appropriate insertion hole 21 according to the position of the track 8. The annular limiting plate 6 can move under the extension and contraction of the spring 23, facilitating the adjustment of the distance between the annular calibration blocks 15. Then, the micro turntable 3 can be rotated to drive the gear 11 on the rotating rod to rotate. The gear 11 drives the gear 12 meshing with it to rotate. The gear 12 drives the lead screw 13 to rotate. The lead screw 13 drives the threaded block 18 to move downward. When the threaded block 18 moves, it can drive the connecting blocks 17 on both sides to move in the slide groove 14, making the movement of the threaded block 18 smoother and more stable. Then, the threaded block 18 drives the threaded sleeve 20 to move through the connecting block 22 and can be inserted into the insertion hole 21. Finally, the nut 19 is... The threaded sleeve 20, screwed onto the outside of the insertion hole 21, can be used to limit and fix it, thereby limiting and fixing the annular limiting plate 6. This allows the annular calibration block 15 on the inner side of the annular limiting plate 6 to limit and calibrate the track 8, preventing the guide wheel 1 from driving the track 7 on the track 8 to rotate and turn, causing the track 8 to deviate and affecting its turning effect. When the guide wheel 1 rotates, it can drive the bearing sleeve 9 to rotate, which in turn drives the connecting plate 5 to rotate. This allows the rotating shaft 10 between the inner sides of the connecting plate 5 to rotate, causing it to rotate through the force generated by the rotation. This allows the rotating shaft 10 to drive the bristles to rotate and clean the groove 4, reducing the adhesion of dust and dirt in the groove 4 and preventing excessive dust and dirt from increasing the weight of the guide wheel 1 and affecting its performance.

[0036] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments.
