Description

Automatic place operation car of insulating block and fastening fastener

Technical Field

The invention relates to an operation vehicle capable of automatically placing insulating blocks and fastening fasteners, and belongs to the technical field of rail paving of rail transit railways.

Background

The sleeper is placed according to setting for the position in ballastless track bed both sides to high-speed railway ballastless track pavement, then fixes the rail on the sleeper, and modern high-speed railway ballastless track's sleeper has complicated attached mounting spare, including heightening backing plate, iron tie plate, gauge apron, fine setting backing plate under the rail, the backing plate under the rail, insulating fast, bullet strip and railway spike etc. the installation of rail on the sleeper is fixed, actually contains the installation of all attached mounting spare fixed. In recent years, with the integration of technology and services, most of the related production enterprises have pre-installed most of the accessory mounts on the sleepers in order to reduce the workload of the track laying work. However, some track laying construction units pre-install most of the accessory installation parts on the sleepers before the track is formally laid on roads. In the following description, we will refer to the sleeper, pre-installed with the accessory mounts, as a pre-installed sleeper.

In the above-mentioned annex, the insulating block can't carry out preinstallation, and it need just can insert it between the spacing boss of rail bottom and the iron tie plate of rail after the rail is installed in place, then the reuse bullet strip is pushed down, and this indispensable operation flow causes very big difficulty for fastener installation in the operation of spreading the rail. In the last decades of automatic track laying research and practice, the installation of steel rails on pre-installed sleepers is limited to the following ways: firstly, manually positioning the steel rail by adopting a mode of fixing one point at multiple points at equal intervals. That is, one rail is manually fixed to one pre-installed sleeper every 2-10 intervals to position the rail. Then, the operation vehicle for fastening the fastener runs on the rail which is fixed and positioned manually, and the sleeve which is arranged on the operation vehicle and used for screwing the spike is used for fastening the other preassembled sleepers which are not fixed with the rail. However, before installing the spike, the insulating block needs to be inserted between the rail bottom on the two sides of the steel rail and the iron base plate limiting table, and the elastic strip is placed at a position where the insulating block can be pressed, and the operation process still needs to be manually completed. The manual intervention is needed at present mainly because the operation is seemingly simple, and if the operation is to be automated, a series of complex coordination actions are needed to realize the operation.

The manual insertion of the insulating blocks and the arrangement of the elastic strips are slow, and the operation standard is difficult to achieve unified specification, which obviously does not meet the requirement of high-quality high-efficiency automatic track laying.

However, a part of the insert blocks 111 of the insulation blocks 109 falling into the first vibration channel 37 and the second vibration channel 38 will not fall into the insert block groove 43, and they will also move forward with the clockwise or counterclockwise vibration of the vibration plate 36 in an unqualified different-direction posture, because the insert blocks 111 of the insulation blocks 109 in different-direction posture do not fall into the insert block grooves 43 of the first vibration channel 37 and the second vibration channel 38, the insulation blocks 109 are higher than the first vibration channel 37 or the second vibration channel 38 in the first vibration channel 37 or the second vibration channel 38, and they will touch the different-direction block eliminating plate 39 to be kicked out when moving forward, and the kicked insulation blocks 109 participate in the vibration plate 36.
