Description

Technical Field

[0001] The utility model relates to a vehicle group used for heavy suspension transportation. Background Art

[0002] When using a heavy-duty overhead conveyor system to transport heavy-loaded workpieces, you will face the situation of using multiple supports or multiple vehicles to connect a load beam to carry the workpiece design and transportation, such as Figure 1 When two-point support or two trolleys are used, it can be ensured that two points on the track are stressed, meeting the uniform stress condition; however, when more than two points are used to design the trolley group, due to problems such as track installation, trolley group assembly accuracy, and load beam deformation, it cannot be guaranteed that each support point can be stressed, thus affecting the service life of the conveying trolley and system stability. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a vehicle group for heavy-duty suspension transportation with a reasonable structural design, which can effectively distribute the force evenly and improve the service life of the transportation vehicle and the system stability.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a vehicle group for heavy-duty suspended transportation, including a front transport trolley and a rear transport trolley, characterized in that it also includes a joint hinged beam, and the front load beam of the front transport trolley is connected with the rear load beam of the rear transport trolley through the joint hinged beam; the joint hinged beam includes an intermediate connecting rod and a rotating joint mechanism, and the rotating joint mechanism is installed at the front and rear ends of the intermediate connecting rod, the rotating joint mechanism at the front end of the intermediate connecting rod is connected to the front load beam, and the rotating joint mechanism at the rear end of the intermediate connecting rod is connected to the rear load beam.

[0005] The rotary joint mechanism described in the utility model includes a horizontal rotary joint and a vertical rotary joint, and the horizontal rotary joint is connected with the vertical rotary joint together; in the rotary joint mechanism at the front end of the intermediate connecting rod, the horizontal rotary joint is connected with the front load beam, and the vertical rotary joint is connected with the front end of the intermediate connecting rod; in the rotary joint mechanism at the rear end of the intermediate connecting rod, the horizontal rotary joint is connected with the rear load beam, and the vertical rotary joint is connected with the rear end of the intermediate connecting rod.

[0006] The utility model has an oil receiving pan installed on the middle connecting rod, and the oil receiving pan covers the upper part of the whole joint hinged beam.

[0007] Compared with the prior art, the utility model has the following advantages and effects:

[0008] The front load beam and the rear load beam are connected by a joint articulated beam. The front load beam and the rear load beam bear the same workpiece respectively. If the track levelness and straightness, and the trolley accuracy change, the position deviation can be compensated by the joint articulated beam under the action of the workpiece gravity. All trolleys are always in contact with the track surface, thereby ensuring that the force is evenly distributed to each support point or trolley, which can effectively distribute the force evenly, improve the service life of the conveying trolley and the system stability, and also meet the requirements of friction drive for the contact surface of the load beam. And because of the segmented structure, when maintaining or replacing the load beam, it is not necessary to replace the entire long beam structure like the traditional one, only the damaged part needs to be replaced, thus saving maintenance costs.
