[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] refer to Figures 1 to 3 The present application provides a wheel anti-derailment device, which mainly includes two wheel brackets 3 and two sets of guide wheels 4. The two wheel brackets 3 are respectively fixed to the two side end surfaces of the overhead crane frame 1 by bolts and other locking members. ( Figure 1 The wheel bracket 3 on one side and a set of guide wheels 4 thereon are shown, and the wheel bracket 3 on the other side and the guide wheels 4 thereon are not shown). The two sets of guide wheels 4 are respectively fixed to the ends of the two wheel brackets 3, and there are two guide wheels 4 in the same set, which are arranged in close contact with the side edge of the track 2.

[0032] When the running wheels are running on the track 2, the two sets of guide wheels 4 roll along the side edges of the track 2 at the same time, thereby providing guidance for the running wheels, avoiding the running wheels from being easily deflected during the lifting process due to insufficient rigidity of the overhead crane bridge, uneven track 2 or improper lifting operation, resulting in running wheel wear and derailment, which would lead to equipment maintenance and affect the continuity of on-site production and product output, thereby improving the operating stability of the track 2, increasing the safety factor, reducing the workload of maintenance personnel and reducing maintenance costs.

[0033] The anti-derailment device for the running wheel is realized by installing a guide wheel 4 at the end of the running wheel of a crane or a gantry crane trolley. When the running wheel deviates during operation, the guide wheel 4 will prevent the running wheel from running in the deviated direction under the supporting stress of the track 2, thereby ensuring the smooth operation of the running wheel, preventing wear and derailment, and improving safety performance.

[0034] The end faces of the two wheel brackets 3 are also provided with track-sweeping baffles 5, which are fixed to the wheel brackets 3 by bolts or other fasteners, or welded to the wheel brackets 3. The track-sweeping baffles 5 are arranged perpendicular to the track 2, that is, arranged vertically, and the lower edge of the track-sweeping baffles 5 is close to the top surface of the track 2. When the equipment is running, under the guidance of the two sets of guide wheels 4, the track-sweeping baffles 5 clean the debris on the track 2, thereby cleaning the track surface along the walking track of the running wheel to ensure the safe operation of the equipment.

[0035] The guide wheel 4 includes a mounting cylinder, which is fixed at both ends of the wheel bracket 3. The rotating shaft is arranged in the mounting cylinder, and the two ends of the mounting cylinder are used to radially position the rotating shaft through the gland. Two sets of bearings are installed inside the mounting cylinder, and the two sets of bearings are respectively arranged at both ends of the rotating shaft and sleeved on the rotating shaft to support the rotation of the rotating shaft and to axially position the rotating shaft. The rotating shaft extending from the lower end of the mounting cylinder is sleeved with a roller, and a locking nut is installed at the very end to fix the roller, thereby preventing the roller from falling off.

[0036] In addition, the outer circumferential surface of the roller has a certain curvature, which is the same as the curvature of the track 2, or is designed according to the curvature of the track 2, so as to fit well with the curved surface of the overhead travelling vehicle track.

[0037] In order to play a buffering role, a buffer 6 can be arranged on the track sweeping baffle 5 to increase the elastic buffering force during collision. The buffer 6 is preferably, but not limited to, a rubber buffer or a spring buffer.

[0038] The utility model also provides a crane, comprising a running wheel anti-derailment device, wherein the running wheel anti-derailment device is specifically the running wheel anti-derailment device described in any one of the above items.

[0039] The utility model also provides a gantry crane, comprising a running wheel anti-derailment device, wherein the running wheel anti-derailment device is specifically the running wheel anti-derailment device described in any one of the above items.

[0040] This application is suitable for installation in industrial production workshops and warehouses where a large number of cranes are needed. It has a simple structure, stable and reliable working performance, and is easy to install. Not only can the track be cleaned of debris by the track sweeping baffle, but it can also ensure that the wheels run smoothly on the track, ensuring safety while also extending the service life of the wheels and tracks.
