Hydraulic steel rail stretcher for railway
The invention relates to the technical field of rail transit equipment, and discloses a hydraulic steel rail stretcher for a railway. The hydraulic steel rail stretcher comprises two rail clamping devices, through holes are formed in the left side and the right side of the rail clamping devices; a rotating shaft is movably sleeved with the rail clamping devices, a rotating piece is fixedly connected to the middle of the rotating shaft, a hydraulic cylinder is movably sleeved with one end of the rotating piece, a clamping block is fixedly connected to the other end of the rotating piece, and supporting ejector rods movably sleeved with the rail clamping device are arranged on the upper portion and the lower portion of one side of the clamping block. With arrangement of a correction device,when the rail clamping devices clamp a steel rail and then stretch the steel rail, two groups of symmetrical support rods on two sides are driven to synchronously move inwards; the trapezoidal block is forced to slide towards one side of the steel rail by extruding the trapezoidal block through the inclined surface of the pressing rod, the spring and the top plate are extruded, and the two sections of steel rails to be butted are corrected through extrusion of the top plates on the two sides so that the centering property of the two sections of steel rails is ensured, and subsequent steel railmachining work is facilitated.
本发明涉及轨道交通设备技术领域，且公开了一种铁路用液压钢轨拉伸机，包括两个夹轨器，所述夹轨器的左右两侧均开设有通孔，所述夹轨器的内部活动套接有旋转轴，所述旋转轴的中部固定连接有转动件，所述转动件的一端活动套接有液压缸，所述转动件的另一端固定连接有夹持块，所述夹持块一侧的上方和下方均设置有与夹轨器活动套接的支撑顶杆。通过矫正装置的设置，当夹轨器对钢轨夹紧后进行拉伸时，会带动两侧对称两组支撑杆同步向内侧运动，通过压杆的斜面对梯形块进行挤压，迫使梯形块向钢轨一侧滑动，并对弹簧和顶板进行挤压，通过两侧顶板的挤压对即将对接的两段钢轨进行校正，保证两段钢轨的对中性，便于后续对钢轨的加工工作。
