The invention relates to the technical field of rail traffic, and discloses a gantry crane rail clamping device which is characterized in that a clamping block is movably sleeved with a sliding groove, a hydraulic control cavity communicated with a machine body is formed in the position, between a hydraulic cavity and a hydraulic hole, in the machine body, and a sliding block is movably sleeved with the hydraulic control cavity; a sleeve is fixedly installed at the position, close to the air guide hole, of the inner side of the hydraulic cavity, a one-way valve is fixedly installed in the air guide hole, an adjusting column is movably connected into the sleeve in a sleeved mode, a limiting groove is formed in the adjusting column in a cross shape, and a sliding rod is movably connected into the limiting groove in a sleeved mode. The stability and power-off self-locking of the rail clamping device are achieved through the arrangement of bottom rolling wheels, a sliding block and an electromagnet, meanwhile, a sleeve is arranged in a hydraulic cavity and connected with an adjusting column in a sleeving mode, and a limiting groove is formed in the adjusting column and connected with a sliding rod in a sleeving mode, so that it can be guaranteed that the rail clamping device still keeps stable due to friction influence in the working process.
本发明涉及轨道交通技术领域,且公开了一种龙门吊夹轨器,滑槽内部活动套接有夹紧块,机体内部位于液压腔与液压孔之间开设有分别与其连通的液压控制腔,液压控制腔内部活动套接有滑块,机体内部的中部位于滑块等高处固定安装有电磁铁,液压腔内侧靠近导气孔位置固定安装有套筒,导气孔内部固定安装有单向阀,套筒内部活动套接有调节柱,调节柱内部呈十字状开设有限位槽,限位槽内部活动套接有滑杆,通过底部滚轮的设置和滑块、电磁铁的设置实现了夹轨器的稳定性和断电自锁,同时在液压腔内部设置有套筒套接调节柱,并且在调节柱内部开设限位槽套接滑杆可以保证夹轨器工作过程中因为摩擦影响仍然保持稳定性。
