Description

Technical Field

[0001] The utility model belongs to the bulk material loading and unloading equipment of railway vehicles, and particularly relates to a parallel four-link balance wheel device. Background Technique

[0002] The shunting locomotive is one of the main equipment in the complete set of equipment of the dumper unloading system, used to tow railway vehicles and position them at the specified positions so that the dumper can complete the dumper operation. The shunting locomotive is the key equipment to realize the high-efficiency automation of the dumper system and has been widely used in the bulk material conveying systems of large enterprises such as ports, steel plants, and energy. The shunting locomotive is composed of a car body, a running wheel device, a guiding wheel device, a coupler pitching arm mechanism, a driving device, a pin lifting device, a position detection device, a cable towing arm, a walkway and railing, a hydraulic system, an electrical system, etc. Among them, the running wheel device is composed of a fixed wheel device and a balance wheel device. The balance wheel device is used to ensure good contact between the wheels and the track and is an important part to ensure the safe production operation of the shunting locomotive.

[0003] At present, there are two known balance wheel devices:

[0004] 1. Balance beam type balance wheel: The structural form of this type of balance wheel device is that the balance beam is hinged to the car body, and two groups of wheels are respectively hinged at both ends of the balance beam. The wheel pressures of the two groups of running wheels are evenly distributed through the hinge points. The disadvantage is that the car body structure is special and is suitable for newly designed shunting locomotives.

[0005] 2. Elastic running wheel: The running wheel device adopts three fixed running wheels and one elastic running wheel. The structural form of the elastic running wheel is that the running wheel set is hinged to the running wheel frame. One end of the running wheel frame is fixed to the car body, and the other end is connected to the car body through a spring. The wheel pressure of this elastic running wheel is uncertain, and the wheel pressure of the running wheel on the opposite side of the shunting locomotive car body is unbalanced.

[0006] In summary, it is very necessary to research and develop a new type of balance wheel device. Summary of the Invention
