Comprising a suspended beam, a first side wall plate, a second side wall plate, two first wheels and two second wheels, the first side wall plate and the second side wall plate are sleeved with the suspended beam in an empty mode, the two first wheels are installed on the first side wall plate side by side, and the two second wheels are installed on the second side wall plate side by side. The first threaded section is provided with a first adjusting nut, and the second threaded section is provided with a second adjusting nut. After the scheme is adopted, the distance between the two second wheels and the lifting point is finally equal to the distance between the two first wheels and the lifting point by independently rotating one corresponding adjusting nut, so that the load uniformity of the four wheels during bearing is ensured, the walking stability of the trolley on a track beam is improved, and the safety of the trolley is improved. The defect that the distance between a single-side wheel and a lifting point can be adjusted only after the trolley is taken away from a track beam is overcome.

Description

Technical Field

[0001] The utility model relates to a monorail trolley which is suitable for quickly adjusting a single-side wall panel on a track beam and belongs to the technical field of lifting equipment. Background Art

[0002] In the existing monorail trolley, two side wall panels are threadedly connected to a hanging beam with a lifting ring, and nuts are welded on the outer sides of the two side wall panels. Each side wall panel assembly is composed of each side wall panel and each wheel axle component, and each wheel axle component includes a wheel, a wheel axle and a bearing. Among them, the two sections of threads of the hanging beam for connecting the two side wall panels are in opposite directions. However, when adjusting the wheels on the track beam, the two side wall panels can only be moved in opposite directions toward the lifting ring or away from the lifting ring relative to the axial direction of the hanging beam. That is, the existing adjustment method of moving the wall panels on both sides of the track beam in and out at the same time can only adapt to the change of track width, but cannot adjust the distance between the wheel on one side and the lifting ring. In practice, it is found that when one side wall panel assembly is installed before installing another side wall panel assembly, there is often an assembly error, resulting in inconsistent spacing between the lifting ring and the wheels on both sides, which will affect the load uniformity when the wheels are loaded. The solution is to remove the trolley from the track beam, reassemble one side of the wall panel assembly after landing, and then adjust the spacing from the wheel on one side to the lifting ring to meet the spacing from the wheel on the other side. However, this results in low work efficiency, especially for high-altitude installation of large-tonnage trolleys. It is a very cumbersome task, and it often happens that installation workers refuse to adjust and manufacturers shirk responsibility. Therefore, the existing monorail trolleys really need to be improved. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a monorail trolley suitable for quickly adjusting a single-side wall panel on a track beam.

[0004] To this end, the utility model adopts the following technical solutions:

[0005] A monorail trolley suitable for quickly adjusting a single-side wall panel on a track beam comprises a hanging beam, a first side wall panel and a second side wall panel which cooperate with the hanging beam in an empty sleeve and are arranged face to face and spaced apart, two first wheels installed side by side on the first side wall panel and two second wheels installed side by side on the second side wall panel. The hanging beam is provided with a hanging point, and the first wheel and the second wheel can be driven by an external force to roll on the lower wing surface of the track beam. The improvement lies in that a first threaded section is provided on one side of the hanging point on the hanging beam and a second threaded section is provided on the other side thereof, a first adjusting nut is installed on the first threaded section, and a second adjusting nut is installed on the second threaded section.

[0006] In order to facilitate the processing of the threads of the hanging beam, as a priority, the thread rotation direction of the first thread segment and the second thread segment is the same. When the two thread segments have the same direction, the first adjusting nut and the second adjusting nut can be used interchangeably.

[0007] As a preference, the first thread segment and the second thread segment of the present invention have opposite thread rotation directions.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] When the monorail trolley placed on the track beam is found during inspection that the distances from the hanging point to the two first wheels and the two second wheels are not equal, the first adjusting nut can be rotated alone to achieve axial movement of the first side wall panel along the hanging beam to adjust the two first wheels, until the distance from the two first wheels to the hanging point is adjusted to be equal to the distance from the hanging point to the two second wheels, or the second adjusting nut can be rotated alone to achieve axial movement of the second side wall panel along the hanging beam to follow the two second wheels, ultimately satisfying that the distance from the two second wheels to the hanging point is equal to the distance from the two first wheels to the hanging point, thereby ensuring the uniformity of the load when the four wheels are bearing, and improving the stability of the trolley walking on the track beam, thereby achieving effective compensation on the track beam for the assembly error caused by the installation of the side wall panel assembly in the prior art, thereby eliminating the need to first remove the trolley from the track beam and then rotate one of the side wall panel assemblies to adjust the distance from the single-side wheel to the hanging point.

[0010] In addition, by adopting the above solution, when the width of the track beam changes, the utility model can also make adaptive adjustments to the wheel spacing on the beam. BRIEF DESCRIPTION OF THE DRAWINGS
