Description

Technical Field

[0001] The utility model relates to an adjusting device, in particular to an adjusting device for a guide wheel, belonging to the technical field of guide wheels. Background Art

[0002] Construction machinery and equipment is the general term for construction machinery used in engineering construction, which is widely used in engineering fields such as construction, water conservancy, electric power, roads, mines, ports, and national defense. There are various types. Construction machinery is an important part of the equipment industry, and the guide wheel is one of the commonly used components of construction machinery.

[0003] In the Chinese patent application publication specification CN219277662U, an adjusting device for a guide wheel is disclosed. By rotating the first nut, the sleeve rotates. At this time, under the rotation of the sleeve, the two-section screw moves in opposite directions, thereby realizing the adjustment of the screw length, adjusting the distance between the adjusting bracket and the truss, and then tightening the crawler of the guide wheel to avoid falling off. Then, the position of the first pin hole is locked by a pin shaft to prevent the sleeve from rotating. In addition, by rotating the second nut along the thread direction in the damping rod, the damping value of the spring is adjusted. According to the different lengths of the spring, the required length value of the spring is adjusted by rotating the second nut. The second partition adjusts the covering angle of the spring through cooperation with the second nut, and then is fixed by a pin shaft according to the second pin hole on the second nut and the second pin hole on the thread in the damping rod to prevent the second nut from rotating.

[0004] In the above patent solution, the damping value of the spring is adjusted by rotating the second nut to drive the second partition. When the damping value of the spring needs to be increased, the spring will generate a large rebound force due to excessive compression. This rebound force will be transmitted to the second partition. As the extrusion force increases, the second partition will receive a large reverse acting force, thereby squeezing the second nut that cooperates with it, resulting in an increase in the adjustment resistance, which will make it more difficult for the worker to rotate the second nut.

[0005] Therefore, an adjusting device for a guide wheel is proposed here. Summary of the Utility Model
