Problems solved by technology
[0003] At present, the existing precise adjustment devices have the following characteristics: mostly manual operation, simple structure, and low cost per device, but require more manpower, and it is difficult to control the positioning accuracy; usually the equipment needs to wait until the cement grouting is poured and solidified. Evacuation, which requires many sets of equipment to work at the same time, thus greatly increasing the cost of each adjustment
In addition, although some adjustment equipment can be evacuated, it is necessary to leave the final support and wait until the cement grouting is poured and solidified before evacuation. The support point and the final support point of the track slab in the middle of the adjustment process need to be switched, so there is a problem of benchmark conversion. Manual fine-tuning again, which affects the work efficiency

The invention discloses a movable precise adjusting device for a track slab, relates to a railway track, in particular to a precise adjusting device for the track slab during the construction of high-speed railway ballastless tracks. The adjusting device comprises a running mechanism, support legs and adjusting mechanisms, wherein the running mechanism consists of a frame, a driving wheel mechanism, a bearing wheel mechanism and a guide wheel mechanism; the driving wheel mechanism and the bearing wheel mechanism are arranged below the frame at intervals; the guide wheel mechanism is arranged below the frame; and no less than one pair of adjusting mechanisms and no less than one pair of support legs are arranged below the frame. In the movable precise adjusting device for the track slab, automatic servo control can be used completely due to the adjusting mechanisms; the support points and end support points of the track slab in an adjusting process are at the same position; and the end support points and the adjusting mechanisms can be separated, so that labor force and equipment are saved and operating efficiency is improved.
Description
(1) Technical field [0001] The invention relates to a railway track, in particular to a mobile track slab precision adjustment device in the construction of a high-speed railway ballastless track. (2) Background technology [0002] Due to the needs of high-speed trains, high-speed railways mainly use slab-type ballastless tracks. The rails are not laid on ordinary sleepers, but on track slabs that have been precisely polished by machine tools to ensure line stability, safety, and low noise. . High-speed railways require the track to have strict smoothness in height and horizontal direction, in order to meet this requirement. The precise positioning of the track plate usually uses the precision measurement control network and advanced fine-tuning measuring instruments to continuously measure the spatial coordinates of each track plate in real time, and compares the theoretical space coordinates with the computer system in real time to give the real-time deviation. Combined ...
