[0002] The guide wheel is an important component in the walking system of large-scale construction machinery. It is located above the crawler track. Its main task is to guide the crawler track to wind correctly and adjust the tension of the crawler track through the tensioning device. The guide wheel not only plays a guiding role, but also has a tensioning function to ensure that the crawler track maintains an appropriate tension state during walking and prevents the crawler track from running off the track or going off the track. Therefore, a high-load-bearing guide wheel is required.

[0003] The guide wheel will be subject to friction during use. Long-term friction will cause it to run poorly, which may reduce the load-bearing capacity of the guide wheel. In addition, the single fixing method of the guide wheel may cause it to slip during operation, reducing its practicality. Utility Model Content

[0010] Preferably, one end of the connecting plate is rotatably mounted with a fixing bolt, and one end of the fixing bolt passes through the connecting plate and extends to the interior of the mounting plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The high-load-bearing guide wheel has a high load-bearing capacity. During daily use, the operator places lubricating oil into the oil storage box through the circular hole, and then slides the baffle through the groove and the pull plate. The baffle then drives the soft plug to be placed inside the circular hole. At this time, the fixing plate is also placed inside the installation groove. The mounting bolt is then turned and screwed into the mounting screw hole to install and fix it. When the wheel body is running, it drives the oil storage box to move, and the lubricating oil in the oil storage box flows through the guide groove to the connection between the wheel axle and the wheel body, thereby maintaining it, reducing friction and improving the load-bearing capacity.

[0013] This kind of high load-bearing guide wheel, during daily use, the operator puts the mounting plate on the outer surface of the clamping block, and then the screw is placed inside the circular groove. At this time, the fastening bolt is turned and screwed into the inside of the clamping block and the mounting plate to fix it. At the same time, the connecting plate is placed on the outer surface of the screw, and then the connecting plate is turned and placed on one end of the mounting plate. Then the fixing bolt is turned and screwed into the inside of the connecting plate and the mounting plate to fix it again. BRIEF DESCRIPTION OF THE DRAWINGS
