Double pillow tamping device

Abstract

The invention discloses a double-sleeper tamping device. The double-sleeper tamping device comprises a box body, a vibrating shaft, an inner clamping oil cylinder, an outer clamping oil cylinder, an inner picking arm, an outer picking arm, an inner side tamping pick, an outer side tamping pick, an air cylinder, check blocks, a guide pillar, and a supporting arm and oil tank assembly. The box body is at least formed by welding a middle body, a cross beam, end plates, outer supporting bosses, stop baffles and hanger plates. The distance between the center of an outer picking arm pin hole in the cross beam of the box body and the central line of the box body is equal to 600 mm + / - 20 mm. The supporting arm and oil tank assembly comprises a supporting arm, two oil tanks and a flywheel guard. The check blocks are arranged between the front end of a piston rod of the outer clamping oil cylinder and a cylinder cover of the outer clamping oil cylinder. The check blocks comprise fixed check blocks and reversible check blocks. Through the utilization of check blocks of different numbers, downward inserting position and clamping travel of the outer side tamping pick can be adjusted, and operation requirements of different sleeper intervals are met. The double-sleeper tamping device is reasonable in structure, and can not only meet station track operations, but also meet main track operations.

Description

Technical field [0001] The invention relates to a tamping car for railway maintenance machinery, in particular to the structure of a tamping device. Background technique [0002] Tamping device is the main working device of large-scale road maintenance machinery tamping vehicle. It is mainly used to tamping the ballast of the sleeper bottom on both sides of the rail to improve the compactness of the ballast of the sleeper bottom, and cooperate with the track lifting device to eliminate the unevenness of the track and enhance the stability of the track. [0003] At present, the DC-32 and DCL-32 double sleeper tamping vehicles used in large quantities on the lines of our country are mainly used for the tamping operation of the main railway line, and the station line within the railway station has been ignored by people, even some station lines It has been in disrepair for a long time and has become a bottleneck in the development of railway transportation. Therefore, it is of great...
