Tunnel bridge screen scarifier
The invention relates to a tunnel bridge screen scarifier. The screen scarifier comprises a frame (1), wherein the frame (1) comprises a front half part and a rear half part by taking a middle part asa boundary; the front half part is provided with a working device, the rear half part is provided with a power device, the front end and the rear end below the frame (1) are respectively provided with a bogie (4), the middle part is provided with an excavating device (2), and an excavating measuring trolley (17) is arranged below the frame (1) between the excavating device (2) and the bogie (4) at the rear end. According to the invention, mechanical screen cleaning of railway tunnels and bridge ballasts can be realized. By arranging the excavating measuring trolley, the reasonable operation space between an excavation guide groove and a sleeper is guaranteed, and the excavation guide groove is prevented from colliding with the end of the sleeper. By adopting a jet fan, the technical effects of ventilation and rapid smoke discharge in case of emergency fire are achieved. By adoption of a drainage ditch excavating device, railway ballasts at a water outlet after excavation of the screenscarifier are excavated loosely, the labor intensity is reduced, and the ballast bed drainage performance is improved.
本发明涉及一种隧道桥梁清筛机，包括车架（1），车架（1）以中部为界包括前半部和后半部，所述前半部布置工作装置，所述后半部布置动力装置，车架（1）下方前后两端分别装有转向架（4），所述中部装有挖掘装置（2），挖掘装置（2）与位于所述后端的转向架（4）之间的车架（1）下方装有挖掘测量小车（17）。本发明能够实现铁路隧道、桥梁道砟的机械化清筛作业。通过设置挖掘测量小车，保证挖掘导槽与轨枕之间的合理作业空间，避免挖掘导槽与轨枕端头相撞。通过采用射流风机，实现通风换气、紧急着火时迅速排烟的技术效果。通过采用排水沟挖掘装置，将清筛车挖掘后排水口处的道砟挖松，降低人力劳动强度，提高道床排水性能。
