Description

Technical Field

[0001] This utility model relates to the field of idler wheel technology, specifically a novel idler wheel for tracked excavators. Background Technology

[0002] An excavator, also known as a digging machine or a soil excavator, is a piece of earthmoving machinery that uses a bucket to dig materials above or below the machine's bearing surface and load them into transport vehicles or unload them into a stockpile. Excavators move by means of tracks, and track guide wheels are used to guide the tracks to rotate correctly and prevent them from deviating or going off track.

[0003] Existing patent CN216886973U discloses a track guide wheel, including a guide wheel, a shaft, an automatic lubrication component, and an oil tank. The guide wheel is provided with a shaft groove, the shaft is located in the shaft groove, the automatic lubrication component is located inside the guide wheel, and the oil tank is located inside the guide wheel.

[0004] The aforementioned patents or existing guide wheels have the following problems:

[0005] The existing idler wheels are difficult to align during installation, and inaccurate alignment can easily lead to problems such as track misalignment, vibration, and abnormal noise. Utility Model Content

[0006] The purpose of this invention is to provide a novel guide wheel for tracked excavators to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a novel tracked excavator guide wheel, comprising a guide wheel, a connecting shaft disposed within the guide wheel, a connecting bracket disposed on the connecting shaft, a positioning structure disposed inside the connecting bracket, the positioning structure comprising a positioning cylinder, the positioning cylinder disposed inside the connecting bracket, a screw connected to the connecting bracket, an adjusting block connected to the screw, a connecting block disposed on the surface of the adjusting block, and the connecting block being connected to the positioning cylinder.

[0008] Preferably, the connecting bracket has a sliding opening inside, the connecting block is located in the sliding opening, and the surface of the connecting block is in contact with the inner surface of the sliding opening.

[0009] Preferably, the connecting bracket has a locking rod inside, and a locking block is connected to the surface of the locking rod. The locking block is connected to the positioning cylinder.

[0010] Preferably, the surface of the card block abuts against the inner side of the connecting bracket.

[0011] Preferably, the positioning cylinder is equipped with a rotatably connected retaining ring.

[0012] Preferably, the end of the connecting shaft is provided with a plug, which is inserted into the retaining ring.

[0013] Preferably, the retaining ring has an insulating ring inside. When the plug is inserted into the retaining ring, it presses against the surface of the insulating ring, and the plug will not press against the inside of the positioning cylinder through the insulating ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] After the connecting shaft is connected to the connecting bracket, the connecting shaft will be inserted into the positioning cylinder. Then the plug will be locked into the retaining ring for positioning. Next, the screw will be rotated. Since the adjusting block is threadedly connected to the screw, the adjusting block will move when the screw is rotated, thereby driving the connecting block to make the positioning cylinder slide inside the connecting bracket. Since the connecting shaft is fixed in the positioning cylinder, the sliding of the positioning cylinder will drive the connecting shaft to adjust the position of the guide wheel, so as to achieve convenient adjustment of the guide wheel position, which is beneficial to the adjustment and alignment of the guide wheel and the track.

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 and Figure 2 This utility model provides a novel tracked excavator guide wheel, including a guide wheel 1, a connecting shaft 2 integrally formed in the guide wheel 1, the connecting shaft 2 being connected to a connecting bracket 3, the connecting bracket 3 being fixed on the excavator, the track being attached to the surface of the guide wheel 1, and the guide wheel 1 also supporting the track. When the track rotates, it will drive the guide wheel 1 to rotate simultaneously, and the guide wheel 1 will guide and support the track. The connecting bracket 3 is provided with a positioning structure 4 inside.

[0023] Please see Figure 3and Figure 4 This utility model provides a novel tracked excavator guide wheel. The positioning structure 4 includes a positioning cylinder 41. The positioning cylinder 41 is installed inside the connecting bracket 3 and is slidably connected to the connecting bracket 3. The connecting bracket 3 is equipped with a rotatably connected screw 42. An adjusting block 43 is threadedly connected to the screw 42. A connecting block 44 is integrally formed on the surface of the adjusting block 43. The connecting block 44 is connected and fixed to the positioning cylinder 41 by bolts. A sliding opening 46 is opened inside the connecting bracket 3. The connecting block 44 is located in the sliding opening 46, and the surface of the connecting block 44 is in contact with the inner surface of the sliding opening 46 to lock the connecting block 44, so as to avoid the positioning cylinder 41 being stressed and causing the connecting block 44 to tilt, thereby improving the stability of the positioning cylinder 41. A locking rod 47 is fixed inside the connecting bracket 3. A locking block 48 is slidably connected to the surface of the locking rod 47 and is connected to the positioning cylinder 41. The locking block 48 is located at a symmetrical position to the connecting block 44, thereby improving the stability of the positioning cylinder 41. The surface of the locking block 48 abuts against the inner side of the connecting bracket 3.

[0024] The positioning cylinder 41 is equipped with a rotatably connected retaining ring 49. The end of the connecting shaft 2 is provided with a plug 410. The plug 410 is inserted into the retaining ring 49. The plug 410 will drive the retaining ring 49 to rotate together due to the rotation of the connecting shaft 2. The retaining ring 49 will rotate in the positioning cylinder 41, which makes the connection of the connecting shaft 2 highly stable. The retaining ring 49 is provided with an isolation ring 411. When the plug 410 is inserted into the retaining ring 49, it will press against the surface of the isolation ring 411. Through the isolation ring 411, the plug 410 will not press against the inside of the positioning cylinder 41, reducing the friction between the plug 410 and the positioning cylinder 41.

[0025] After the connecting shaft 2 is connected to the connecting bracket 3, the connecting shaft 2 will be inserted into the positioning cylinder 41. Then the plug 410 will be locked into the retaining ring 49 for positioning. Then the screw 42 is rotated. Since the adjusting block 43 is threadedly connected to the screw 42, the adjusting block 43 will move when the screw 42 rotates, thereby driving the connecting block 44 to make the positioning cylinder 41 slide inside the connecting bracket 3. Since the connecting shaft 2 is fixed in the positioning cylinder 41, the sliding of the positioning cylinder 41 will drive the connecting shaft 2 to adjust the position of the guide wheel 1, so as to achieve convenient position adjustment of the guide wheel 1, which is beneficial to the adjustment and alignment of the guide wheel and the track.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
