Hydraulic anchoring manipulator for railway vehicle

Abstract

The invention discloses a hydraulic anchoring manipulator for a railway vehicle. The hydraulic anchoring manipulator for the railway vehicle is mainly composed of a lifting arm, a telescopic arm 5 and a tail end gripper. The hydraulic anchoring manipulator is driven hydraulically and is composed of the lifting arm, the telescopic arm and the tail end gripper. A four-bar mechanism of a double-bar structure is adopted for the lifting arm, and the strength of critical components such as a telescopic cylinder and supporting rods is checked. A hydraulic system adopts the energy-saving design, and the position of the manipulator is locked by a hydraulic lock. Redundancy control is carried out through combination of program interlocking and the travel time to guarantee the reliability of the system. Through the field use, the manipulator can achieve automatic searching of the spatial position of the vehicle, automatic hooking and unhooking of a draw gear and positioning and position locking of the vehicle within the horizontal distance of 1.5 m, reaches the design goal and can achieve safe and high-efficiency production.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a manipulator, in particular to a railway vehicle hydraulic anchoring manipulator. Background technique [0002] When railway vehicles are loaded and unloaded in ports, factories and mines, etc., there are many occasions where they need to be fixed, especially coal special vehicles. On the coal unloading operation line of the dumper, many fixing methods are adopted, such as wheel clamps, pressure beams, leaning plates, and car stoppers. However, there is no mature vehicle fixing equipment for the screw unloaders that are widely used in coal terminals, power plants, and various mines. When the unloading machine, especially multiple unloading machines, is working at the same time, the side wall of the spiral blade scrapes against the carriage to cause the vehicle to move. After the vehicle moves, it needs to return to the original predetermined unloading position, w...

Problems solved by technology

However, there is no mature vehicle fixing equipment for the screw unloaders that are widely used in coal terminals, power plants, and various mines.

When the unloading machine, especially multiple unloading machines, is working at the same time, the side wall of the spiral blade scrapes against the carriage to cause the vehicle to move. After the vehicle moves, it needs to return to the original predetermined unloading position, which increases the auxiliary time and affects the operation safety and production efficiency.
