Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spherical auxiliary wheel, concretely is spherical auxiliary wheel for aerial trolley. BACKGROUND

[0002] Aerial rail loop shuttle trolley (referred to as aerial trolley) is a suspended monorail shuttle trolley system. Its feature is that the track is above the train, and the track line is fixed in the air through a supporting and fixing structure. The device moves along the track line in the air. The system can be applied to material conveying environments with complex ground conditions or insufficient ground space.

[0003] Since the aerial rail moves ground traffic to the air, it can alleviate the problem of complex ground conditions and equipment arrangement without expanding the existing ground facility space. It overcomes the disadvantages of other ground layout logistics conveying systems and has many outstanding features in construction and operation.

[0004] The aerial trolley is a device for material conveying using monorail suspension fixation, so it needs special auxiliary devices to maintain balance and stability when driving along the track in the air. The related guiding auxiliary structure helps the device to accurately drive along the track. The traditional auxiliary device is a fixed guide wheel structure. This scheme can fix the guiding effect of the aerial trolley driving along the loop line. It generally uses the structure to clamp the track to guide the main body of the aerial trolley in the air.

[0005] In addition, in addition to the above-mentioned fixed guide wheel structure, the driving of the aerial trolley can be further stabilized and guided by the auxiliary wheel support.

[0006] The traditional auxiliary device is mostly a fixed structure, which is difficult to adapt to complex and variable track environments, has high maintenance cost, and lacks operation flexibility. Its design lacks flexibility and cannot be self-adapted to different track conditions, resulting in poor stability in complex environments and increasing the risk of operation and maintenance difficulty. In addition, the fixed auxiliary device is easy to wear during long-term use, and the replacement parts are frequent, which further increases the operation cost. Therefore, the auxiliary guide wheel is used to support and guide the vehicle body to ensure the stable operation of the vehicle body.

[0007] The common guide wheel structure is generally directly designed by adopting the bearing rubber-coated wheel mode, the auxiliary wheel of this type can only roll along the fixed shaft, and good auxiliary supporting effect can be ensured when the aerial trolley travels on the straight track, but when the aerial trolley travels along the curved track, the auxiliary wheel of this type cannot move in the rolling friction mode due to the axial fixation, and in most cases, the sliding friction mode is adopted. Thus, the auxiliary guide wheel plays a smaller role when the device travels to the curved track, and even causes the hard sliding friction to affect the power and cause the device vibration and the like, thereby affecting the overall working efficiency.

[0008] Meanwhile, the structure is complex, the installation and debugging process is tedious, and the time consumption is relatively long, and these problems not only limit the application range of the aerial trolley, but also affect the reliability and economy in the actual operation. Therefore, it is particularly important to develop a new type of auxiliary device which can be self-adapted to different tracks, reduce the maintenance cost and improve the operation flexibility.

[0012] Preferably, a notch with a suitable size is formed on the mounting position of the main body mounting plate of the aerial trolley, so as to ensure that the universal bearing ball extends out of the notch to play a supporting role.
