One, support wheel
In the work, the support rollers should be avoided for a long time in muddy water. After the work is completed every day, the one-sided crawler should be propped up, and the walking motor should be driven to shake off the dirt, gravel and other debris on the crawler. The roller must be kept dry during construction in winter, because there is a floating seal between the outer wheel of the roller and the shaft. If there is water, it will freeze at night. When the excavator is moved the next day, the seal and ice will be contacted. Scratches cause oil leakage. The damage of the supporting rollers will cause many failures, such as walking deviation and walking weakness.
2. Carrier wheel
The sprocket wheel is located above the X frame, and its function is to maintain the linear motion of the chain track. If the sprocket wheel is damaged, the track chain track cannot maintain a straight line. The carrier wheel is filled with lubricating oil at one time. If the oil leaks, you can only replace it with a new one. During work, try to avoid the supporting wheel soaking in muddy water for a long time. Usually, keep the X-frame inclined platform clean. The accumulation of mud and gravel prevents the rotation of the carrier wheel.
Three, guide wheel
The guide wheel is located in front of the X frame, and it is composed of a guide wheel and a tension spring installed inside the X frame. Keep the guide wheel in front during operation and walking, so as to avoid abnormal wear of the chain rail, and the tension spring can also absorb the impact of the road surface during work and reduce wear.
Fourth, the driving wheel
The drive wheel is located behind the X frame, because it is directly fixed on the X frame and has no shock absorption function. If the drive wheel travels in the front, it will not only cause abnormal wear on the drive ring gear and chain rail, but also adversely affect the X frame. The X frame may have problems such as early cracking. The protective plate of the walking motor can protect the motor. At the same time, some dirt and gravel will enter the internal space, which will wear the oil pipe of the walking motor. The moisture in the soil will corrode the joints of the oil pipe, so the protective plate should be opened regularly. Clean up the dirt inside.
Five, track
The track is mainly composed of track shoes and chain track sections. The track shoes are divided into standard plates and extended plates. Standard plates are used for earthwork conditions, and extension plates are used for wetland conditions. The wear on the track shoe is the most serious in the mine. When walking, the rubble sometimes gets stuck in the gap between the two boards. When it comes into contact with the ground, it will squeeze the two boards, and the track shoe is prone to bending. Deformation and long-term walking will also cause cracking problems in the bolt fixation of the track shoe. The chain track section is in contact with the drive gear ring and is driven by the gear ring to rotate. If the track is too tight, it will cause early wear of the chain track, ring gear and guide wheel. Therefore, the tension of the track should be adjusted according to different construction road conditions.
