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-bar balance wheel device vertically installed. Background Art

[0002] The shunting locomotive is one of the main equipment in the complete set of equipment of the dumper unloading system, which is 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 consists of a vehicle 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 towing cable arm, a walkway and railing, a hydraulic system, an electrical system, etc. Among them, the running wheel device consists 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 two groups of balance beams are respectively hinged to both ends of the tie rod, and two groups of balance wheel groups are respectively hinged to the other ends of the two groups of balance beams. The wheel pressures of the two groups of running wheels are evenly distributed through the hinge points. The disadvantage is that the vehicle 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 group is hinged to the running wheel frame. One end of the running wheel frame is fixed to the vehicle body, and the other end is connected to the vehicle 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 body is unbalanced.

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

[0007] The utility model aims to avoid the disadvantages and deficiencies existing in the above-mentioned prior art, and provides a new type of parallel four-bar balance wheel device which is not only reasonable in design, compact in structure, safe and reliable, but also low in cost.

[0008] The object of the present utility model is achieved by the following technical solutions: A novel parallel four-link balance wheel device is vertically installed on a shunting locomotive body, and includes a balance beam (1), a pull rod (2), a support (3) and a balance wheel group (4). The support (3) is fixed on the side of the shunting locomotive body, the lower end of the balance beam (1) is hinged to the support (3), the pull rod (2) is arranged above the shunting locomotive body, both ends of the pull rod (2) are hinged to the upper end of the balance beam (1), and the balance wheel group (4) is hinged to the balance beam (1). The balance beam, the pull rod, the support and the balance wheel group are hinged together to form a parallel four-link mechanism.

[0009] Compared with the prior art, the present utility model has the following advantages: 1. Adopting a parallel four-link mechanism, the wheel pressure is balanced, simple and reliable. 2. Reasonable design and compact structure; 3. Convenient installation and maintenance, and low cost. Brief Description of the Drawings
