Problems solved by technology
At present, most engineering maintenance machinery operation trolleys use one traction bar at the front and rear for one-way traction. When the working trolley is located on a curved road section, the outer rail of the rail is super high on the curve, and the frame of the rail car is offset relative to the curve of the rail. , resulting in that the working trolley cannot be retracted and retracted on the curved route, but can only be retracted and retracted on the straight route, thus affecting the working efficiency

Embodiment Construction
[0070] In order to better understand the present invention, the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0071] Such as figure 1 Shown is a schematic structural view of a preferred example of a rail car that can automatically swing and retract two-way operating trolleys according to the present invention. figure 1 The shown rail car can automatically swing the curve retractable bidirectional operation trolley and is installed on the railway engineering maintenance vehicle. The rail vehicle can automatically swing the curve retractable bidirectional operation trolley including the trolley frame 1, and the trolley frame 1 is provided with four wheels in total. Seat 2, four trolley wheels 3 are set on the four wheel bases 2, four lifting cylinders 4 are installed above the four corners of the front / rear side of the trolley frame 1, and two Lifting guide bracket 5, lifting guide bracket 5 is connec...

The invention relates to an automatic swing curve retraction and release bidirectional operation trolley for a rail car, and a corresponding trolley curve retraction and release method thereof. The bidirectional operation trolley comprises a trolley frame (1), a lifting device (4) is arranged above the trolley frame (1), a lifting guide support (5) is also arranged at the upper part of the trolleyframe (1), and the lifting guide support (5) is connected with a frame of a railway engineering maintenance vehicle. The operation trolley is characterized in that a transverse moving beam (7) is arranged on the lower portion of the lifting guide support (5), a trolley transverse moving swing device is connected between the transverse moving beam (7) and the trolley frame (1), a traction device is connected between the trolley frame (1) and the frame of the railway engineering maintenance vehicle, and at least one locking mechanism (12) is arranged on the trolley frame (1). The bidirectionaloperation can be met, the structure is compact, and the occupied space is small; and the lifting guide support is arranged, so that the trolley rises to the designated position under the action of thelifting guide support. A bolt type locking device is adopted, so the structure is simple and reliable.
Description
technical field [0001] The invention relates to a curved retractable operation trolley, in particular to an automatically swingable curved retractable bidirectional operational trolley for rail vehicles, which belongs to the technical field of engineering equipment. Background technique [0002] Railway engineering maintenance vehicles require different operating devices according to different maintenance requirements (such as rail flaw detection, ballast bed suction, rail grinding, rail milling, ballast bed sand removal, ballast bed snow removal, ballast bed coal removal, etc.), and these operating devices need to be installed in the On an independent, easy-to-operate and flexible working trolley, the working trolley realizes the positioning of the working device and the rail and moves along the rail to complete the corresponding functional requirements. At present, most engineering maintenance machinery operation trolleys use one traction bar at the front and rear for one-...
