Abstract
Description
Technical Field
[0001] The utility model relates to a guide wheel, in particular to an adjustable guide wheel, belonging to the technical field of guide wheels. Background Art
[0002] An excavator is a heavy-duty mechanical equipment used in earthworks, construction and other fields. It is usually composed of a working device, a slewing mechanism, a power unit, a transmission control mechanism, a traveling mechanism and auxiliary equipment. According to its traveling mode, we can usually divide it into wheeled excavators and crawler excavators.
[0003] Crawler excavators are widely used due to their superior passability and stability, and guide wheels are a more important component of crawler excavators. In real life, we can understand that with the long-term use of crawler excavators, due to the wear between various parts, the crawler tracks will become loose, thereby reducing their stability during walking. However, in the existing technology, most guide wheels do not have an adjustment function. Then, when the crawler tracks become loose, people need to disassemble the crawler tracks to adjust their tightness, which is not only time-consuming and laborious for the staff, but also delays the work progress of the excavator. Utility Model Content
[0004] The utility model provides an adjustable guide wheel to solve the problem that people need to dismantle the crawler belt to adjust the tightness because the guide wheel in the prior art has no adjustment function.

[0006] The bottom end of the adjusting screw rod is rotatably connected to a U-shaped frame, the inner wall of the U-shaped frame is fixedly connected to a driving wheel, the inner wall of the fixed cylinder is slidably connected to an adjusting arm, and the outer surface of the adjusting arm is fixedly connected to a symmetrical limit block.
[0007] Preferably, a symmetrical reserved groove is opened on the outer surface of the fixed tube, and the two limit blocks extend to the outside of the fixed tube and are slidably connected to the fixed tube. The limit blocks extend to the outside of the fixed tube through the reserved groove and are slidably connected to the fixed tube through the reserved groove.
[0008] Furthermore, the mounting plate is mounted on the outer surface of the excavator chassis, and the driving wheel is in contact with the outer surface of the adjusting arm. As the driving wheel moves downward, the adjusting arm can be driven to slide outward.
[0009] Preferably, one end of the adjustment arm away from the mounting plate is fixedly connected to a mounting frame, the inner wall of the mounting frame is rotatably connected to a support shaft, the mounting frame can move synchronously with the adjustment arm, the support shaft passes through the mounting frame and both ends extend to the outside of the mounting frame.
[0010] Furthermore, the outer surface of the support shaft is fixedly connected to a guide wheel, and the outer surface of the guide wheel is covered with a track. The guide wheel can guide the movement of the device. The outer surface of the guide wheel is in contact with the inner surface of the track. As the guide wheel moves, the loose track can be tightened, thereby achieving tightness adjustment of the track.
[0011] Specifically, the reserved holes opened on the outer surface of the mounting plate are respectively located at the four corners of the mounting plate, and a group of threaded holes are opened on the outer surface of the excavator chassis. When installing the mounting plate, the staff can use screws and install the mounting plate on the excavator chassis through the reserved holes opened at the corners of the mounting plate and the threaded holes opened on the outer surface of the excavator chassis.
[0012] The utility model provides an adjustable guide wheel, which has the following beneficial effects:
[0013] The adjustable guide wheel is arranged through the cooperation between the excavator chassis, the adjustment mechanism and the guide wheel. People can adjust the tightness of the track by adjusting the position of the guide wheel. Workers no longer need to disassemble the track for tension adjustment. This not only saves time and effort for the workers, but also effectively ensures the work progress of the excavator at the construction site.
[0014] The adjustable guide wheel can make it easier for people to adjust the tightness of the track through the action of the adjusting handle, the adjusting screw rod, the U-shaped frame, the driving wheel, the adjusting arm and the guiding wheel. By adjusting the screw rod and the driving wheel to move downward synchronously, the adjusting arm can be driven to slide outward. At this time, the track can be tightened under the action of the guiding wheel, thereby achieving a more convenient adjustment of the loose track to a tight state. BRIEF DESCRIPTION OF THE DRAWINGS
