Embodiment Construction
[0034] A preferred embodiment of the rail tamping vehicle of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0035] figure 1 The shown line tamping vehicle 1 has an elongated vehicle frame 2, and the two ends of the vehicle frame 2 are supported by a bogie type running mechanism 3, and the running mechanism 3 can drive the vehicle frame 2 on a road by using the running driving mechanism 7 installed thereon. Walk on the track 6 that steel rail 4 and sleeper 5 form. A driver's cab 8 and a working room 9 provided with a central controller 10 are arranged on the vehicle frame 2 . In order to check the track 6 position, there is a cover leveling and dialing reference system 11. The working direction of line tamping vehicle 1 is represented by arrow 12 .
[0036] The working trolley 13 is located between the two bogie-type running mechanisms 3, its front end is supported on the vehicle frame 2 and can move longitudinally, a...

Provided is a track tamping wagon. A tamping device of the track tamping wagon is provided with two inner side tamping frames arranged along the transverse direction perpendicular to the mechanical vertical direction and close to the mechanical center and two outer side tamping frames. A tamping unit on the track tamping wagon is connected with a set of outer side tamping mechanism arranged on the mechanical vertical end and a set of inner side tamping mechanism through an eccentric shaft and an opening-closing mechanism, and the height of the tamping unit is singly adjusted through a height adjusting driving mechanism. Each tamping mechanism is provided with a tamping packer, and each side of a steel rail corresponds to a tamping frame, namely four tamping frames exist. Each tamping frame is provided with two tamping units which are vertically distributed in the mechanical front and back direction, and two sets of tamping units are symmetrically arranged on two sides of a vertical symmetrical face transversely parallel to the mechanical vertical direction. The tamping device is installed on a working trolley capable of vertically moving relative to a machine frame supported on a steering frame, the front end of the working trolley is supported on the machine frame according to the mechanical operation direction, and the back end of the working trolley is supported on the track through a steering type walking mechanism.
Description
technical field [0001] The invention relates to a track tamping vehicle, which is used for tamping main lines and turnout lines of ballasted tracks, and belongs to the field of large-scale road maintenance machinery. Background technique [0002] The track tamping device is a working device on the tamping car for tamping the ballast of the sleeper foundation on both sides of the rail. By tamping the ballast on both sides of the rail, the compactness of the ballast at the bottom of the sleeper is improved, and at the same time, it cooperates with the track lifting device to eliminate the deviation of the track, so that the track is smooth and stable. [0003] A tamping device of this type is known from GB2267304, which has four tamping units which can each be moved largely independently laterally. In this way, tamping can also be performed on switch sections with uneven rail runs. In order to move the two outer tamping device frames as much as possible, the upper and lower ...
