Problems solved by technology

At present, most engineering maintenance machinery operating trolleys still use one traction rod for one-way traction at the front and rear. When the working trolley is located on a curved road section, the outer rail of the rail has superelevation on the curve, and the frame of the operating vehicle has a certain difference relative to the curve of the rail. Offset, the working trolley cannot be retracted on the curved route, but can only be retracted on the straight route, thus affecting the working efficiency

Abstract

The invention discloses a bidirectional operation type trolley capable of being locked and released at a curve section for a rail car. The bidirectional operation type trolley comprises a trolley frame (5), four axles (2) are arranged at the front and back of the trolley frame (5) in total, the four axles (2) are connected with four trolley wheels (3), four lifting oil cylinders (4) are arranged above the four corners of the trolley frame (5), four lifting guide plates (7) are further arranged at the portion, on the upper portion of the edge of the trolley frame (5), of a railway engineering maintenance vehicle, the inner side surfaces of the lifting guide plates (7) are located on the inner side of the edge of the trolley frame (5), trolley transverse moving swing oil cylinders (1) are connected between the lifting guide plates (7) and the trolley frame (5), the other ends of the trolley transverse moving swing oil cylinders (1) are connected to trolley transverse moving swing oil cylinder seats (11) on the trolley frame (5), the front portion and the rear portion of the trolley frame (5) in the longitudinal direction are connected with one ends of traction rods (6) correspondingly, and the other ends of the traction rods (6) are connected to the railway engineering maintenance vehicle.

Description

technical field [0001] The invention relates to a curvilinear retractable bidirectional operating trolley for rail vehicles. It 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 sanding, ballast bed snow removal, etc.), and these operating devices need to be installed in an independent, convenient On the operating trolley with flexible movement, the positioning of the operating device and the rail and movement along the rail can be realized through the operating trolley, so as to complete the corresponding functional requirements. At present, most engineering maintenance machinery operating trolleys still use one traction rod for one-way traction at the front and rear. When the working trolley is located on a curved road sec...
