Embodiment Construction

[0017] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but not to be construed as a limitation of the present invention.

[0018] like figure 1 , figure 2 As shown in the present invention, a self-propelled concrete vibrating trolley used for a track bed, the main part is composed of a frame (11) and a lifting mechanism (14) that moves vertically relative to the frame (11). The bottom of the frame is equipped with a track wheel (5) and a traveling motor (10) that drives the track wheel (5). Four slide rails (3) vertically passing through the lifting mechanism (14) are installed on the outer side of the frame (11), and a lifting screw (2) vertically passing through the lifting mechanism (14) is installed in the center of the frame (11). , the lifting screw...

Abstract

The invention relates to railway maintenance mechanical equipment, in particular to a self-propelled concrete vibrating trolley for a ballast bed, which comprises a frame, a vibrating unit and a lifting mechanism capable of vertically moving relative to the frame, and track wheels and a traveling motor for driving the track wheels are mounted at the bottom of the frame. Four sliding rails vertically penetrating through the lifting mechanism are installed on the outer side of the rack, a lifting lead screw vertically penetrating through the lifting mechanism is installed in the center of the rack, the lifting lead screw is connected with a lifting motor, and the vibrating units are installed on the lifting mechanism. According to the invention, the mechanization of concrete vibration operation is realized, so that the vibration area covers the cross section of a ballast bed without omission, the problems of vibration omission, excessive vibration and the like are effectively avoided, and the vibration operation efficiency is improved.

Description

technical field [0001] The invention relates to railway maintenance machinery and equipment, in particular to a self-propelled concrete vibrating trolley used for track beds. Background technique [0002] The ballastless track of high-speed railway has remarkable characteristics such as small geometric displacement of track, good track smoothness, high structural reliability, and small maintenance workload. Therefore, it has been widely used in high-speed railway, passenger dedicated line and intercity rail transit. Affected by the structural form of ballastless track, the limit requirements of mix ratio parameters, the durability evaluation index for specimens, and the human factors in construction, the track bed concrete of double-block ballastless track is very prone to splay corner cracks, transverse through cracks and non-linear cracks. Regular tortoise cracks, when there is freeze-thaw damage, the cracks provide a channel for the outside rain and snow to enter the inte...
