Abstract

An overhead traveling vehicle and an overhead traveling vehicle fault processing system are provided. The overhead traveling vehicle includes: an overhead traveling vehicle main body; a main walking part, installed on the overhead traveling vehicle main body and configured to drive the overhead traveling vehicle main body to walk on tracks; an auxiliary walking part, installed on the overhead traveling vehicle main body and configured to drive the overhead traveling vehicle main body to walk on the tracks; and a control part, configured to control one of the main walking part and the auxiliary walking part to be on the tracks and to control the other one of the main walking part and the auxiliary walking part to leave the tracks.

First claim

The invention claimed is:

1. An overhead traveling vehicle, comprising:
an overhead traveling vehicle main body;
a main walking part, installed on the overhead traveling vehicle main body and configured to drive the overhead traveling vehicle main body to walk on tracks;
an auxiliary walking part, installed on the overhead traveling vehicle main body and configured to drive the overhead traveling vehicle main body to walk on the tracks;
a control part, configured to control one of the main walking part and the auxiliary walking part to be on the tracks and to control the other one of the main walking part and the auxiliary walking part to leave the tracks;
the control part comprises a first control part, wherein the first control part comprises first lifting parts, which are installed on front and rear sides of the overhead traveling vehicle main body in a walking direction along the tracks, the first lifting part is connected with the auxiliary walking part, and a distance of a joint of the first lifting part with the auxiliary walking part and the tracks is variable, so that the auxiliary walking part is on the tracks or leaves the tracks; and
a position limiter, wherein the position limiter is located on the overhead traveling vehicle main body and configured to limit a lifting position of the first lifting part.

2. The overhead traveling vehicle according to claim 1 , wherein the first lifting part comprises a first lifting driver and a first adjusting part, the first lifting driver is connected with the first adjusting part, and the first adjusting part is connected with the auxiliary walking part, and wherein the first lifting driver adjusts a position or a shape of the first adjusting part, so as to enable the auxiliary walking part to be on the tracks and enable the main walking part to leave the tracks, or enable the auxiliary walking part to leave the tracks and enable the main walking part to be on the tracks.

3. The overhead traveling vehicle according to claim 2 , wherein the first adjusting part is a first telescopic part, the first lifting driver drives the first telescopic part to elongate or shorten, and wherein the first telescopic part is elongated, so that the distance between the joint and the tracks is reduced, and the first telescopic part is shortened, so that the distance between the joint and the tracks is increased.

4. The overhead traveling vehicle according to claim 2 , wherein the first adjusting part is a first rotating part, which has an end fixed relative to the overhead traveling vehicle main body, and the first lifting driver drives an end of the first rotating part connected with the auxiliary walking part to rotate, so that the distance between the joint and the tracks is changed.

5. The overhead traveling vehicle according to claim 2 , wherein the first adjusting part comprises a sliding rail and a sliding block which are arranged on the overhead traveling vehicle main body, the sliding block is connected with the auxiliary walking part, and the first lifting driver drives the sliding block, so that the sliding block moves on the sliding rail along a direction towards the tracks or a direction away from the tracks.

6. The overhead traveling vehicle according to claim 1 , wherein the control part comprises a second control part configured to control the main walking part to be on the tracks or to control the main walking part to leave the tracks.

7. The overhead traveling vehicle according to claim 6 , wherein the second control part comprises a second lifting part installed on the overhead traveling vehicle main body and connected with the main walking part, and wherein a distance between a joint of the second lifting part with the main walking part and the tracks is variable, so that the main walking part is on the tracks or leaves the tracks.

8. The overhead traveling vehicle according to claim 7 , wherein the second lifting part comprises a second lifting driver and a second adjusting part, the second lifting driver is connected with the second adjusting part, and the second adjusting part is connected with the main walking part, and wherein the second lifting driver adjusts a position or a shape of the second adjusting part, so as to enable the main walking part to be on the tracks and enable the auxiliary walking part to leave the tracks, or enable the main walking part to leave the tracks and enable the auxiliary walking part to be on the tracks.

9. The overhead traveling vehicle according to claim 1 , wherein the auxiliary walking part comprises a walking motor, linkage shafts and auxiliary walking wheels, and wherein the walking motor rotates to drive the linkage shafts to rotate, and the rotation of the linkage shafts drives the auxiliary walking wheels to rotate.

10. An overhead traveling vehicle fault processing system, comprising:
an overhead traveling vehicle, comprising:
an overhead traveling vehicle main body;
a main walking part, installed on the overhead traveling vehicle main body and configured to drive the overhead traveling vehicle main body to walk on tracks;
an auxiliary walking part, installed on the overhead traveling vehicle main body and configured to drive the overhead traveling vehicle main body to walk on the tracks; and
a control part, configured to control one of the main walking part and the auxiliary walking part to be on the tracks and to control the other one of the main walking part and the auxiliary walking part to leave the tracks;
a fault detector, configured to detect a fault of the main walking part; and
a processor, configured to send a control signal to the control part responsive to that the fault detector detects a fault, so that the control part controls the auxiliary walking part to be on the tracks and controls the main walking part to leave the tracks.

11. The overhead traveling vehicle fault processing system according to claim 10 , wherein the control part comprises a first control part configured to control the auxiliary walking part to be on the tracks or to control the auxiliary walking part to leave the tracks.

12. The overhead traveling vehicle fault processing system according to claim 11 , wherein the first control part comprises first lifting parts, which are installed on front and rear sides of the overhead traveling vehicle main body in a walking direction along the tracks, the first lifting part is connected with the auxiliary walking part, and a distance of a joint of the first lifting part with the auxiliary walking part and the tracks is variable, so that the auxiliary walking part is on the tracks or leaves the tracks.

13. The overhead traveling vehicle fault processing system according to claim 12 , wherein the first lifting part comprises a first lifting driver and a first adjusting part, the first lifting driver is connected with the first adjusting part, and the first adjusting part is connected with the auxiliary walking part, and wherein the first lifting driver adjusts a position or a shape of the first adjusting part, so as to enable the auxiliary walking part to be on the tracks and enable the main walking part to leave the tracks, or enable the auxiliary walking part to leave the tracks and enable the main walking part to be on the tracks.
