Meanwhile, when the rail inspection trolley passes through the gaps between the steel rail and the guard rail (1), the steel rail and the switch rail (2) and the turnout switch point (3), the device designed in the traditional mode passes through the gaps, and the guide wheel is easy to clamp in the gaps; however, if the manual measurement is selected instead of using the detection device, the efficiency is low, the workload is large, the workers are hard, and the quality of the measured data is not enough and has errors.
The invention discloses a spring jacking device, which is a steel rail surface jacking device, wherein guide wheels can be always close to a steel rail positioning surface, the jacking device is arranged on the left side of a rail inspection trolley and close to the inner side of a steel rail in the traveling direction, and guide wheels on two sides can be tightly close to the side surface of a steel rail head, so that the advance of the trolley is not influenced, and the measurement can be carried out on a road section with a changed rail gauge. The rail inspection device has the advantages that the walking stability of the rail inspection device can be guaranteed, and the efficiency of measurement work and the precision of measurement data can be improved.

The spring jacking device mainly comprises six basic components, namely a guide rod, a sleeve, a gear, a rack, a spring and a handle, and simultaneously, the components participating in the work comprise a steel rail, a side beam, a guide wheel and a sliding block.
The diameter of the guide wheel is less than 230mm, and the guide wheel can smoothly pass through the gap between (1) the steel rail and the guard rail, (2) the steel rail and the switch rail, and (3) the turnout switch;
the sleeve is connected with the sliding block, the sliding block is connected with the guide wheel mounting seat on the left side of the side beam, when the guide wheel is not in contact with the inner side face of the rail head of the steel rail, the spring pushes the sleeve to move outwards until meeting a stop, and the relative perpendicularity of the guide wheel and the inner side face of the steel rail is always kept;
the gear rack mechanism is used for rotating the gear through the handle and then driving the rack, when the rack is fixed with the sleeve, the sleeve drives the guide wheel to move inwards, and the guide wheel is released after the handle is pressed, so that the guide wheel is tightly attached to the inner side of the rail head of the steel rail by utilizing the elasticity of the spring;
when the guide wheel in the spring jacking device is used for measurement, the guide wheel is positioned at the outer side of the left steel rail, and the guide wheels at the symmetrical positions at the right side are fixed, so that the guide wheels at two sides can be tightly attached to the outer side surface of the rail head of the steel rail;
the positioning position of the displacement sensor on the rail surface of the steel rail is judged according to the scales, when the adjustment is completed and needs to be fixed, the sliding rail is fixed relative to the sliding block through the bolt, and the sleeve is connected with the sliding block, so that the damping effect can be achieved;
the auxiliary guide wheel of the spring jacking device is clamped on the rail head of the steel rail, so that the problem of transverse displacement of the trolley can be solved.
