Description

TECHNICAL FIELD

[0001] The utility model relates to the field of subway construction technology especially four hanging point horizontal moving device. BACKGROUND

[0002] In the design of subway lines, in order to meet the setting of the station, it is impossible to build in a straight line, and it is very common to build in a curve. In order to ensure the running speed and safety of the subway, the outer rail is designed to be higher than the inner rail. In this way, when the train turns, the resultant force of gravity and support force will provide a component force pointing to the center of the circle, thereby reducing the lateral pressure of the outer rail and protecting the track and wheels from wear and tear. At the same time, if the train turns too fast, it will generate a large centrifugal force, which can easily cause derailment. By adjusting the height difference of the track, the centrifugal force can be effectively balanced to ensure the safe passage of the train through the curve. This design not only improves the safety of train travel, but also prolongs the service life of the track and wheels.

[0003] However, during construction, the roadbed is high on one side and low on the other. If the lifting appliance is lowered horizontally, the floating plate or track panel at the high roadbed end will land first, and the other end at the low roadbed end will land later. At the same time, the center line of the curved track and the center line of the roadbed do not coincide, so it is often necessary to push and pry the floating plate or track panel to align it, which is difficult and very inefficient. Moreover, the floating plate or track panel pushed and pried by hand will sway, which is also very unsafe. SUMMARY

[0004] To solve the above technical problems, the utility model provides a four-hanging-point horizontal moving device. The device has two horizontal moving frames, each of which can move horizontally left and right independently. Four winches can be controlled to lift or lower individually, in pairs, or simultaneously, realizing four-point horizontal moving operation and meeting the requirements of on-site construction.

[0005] A four-hanging-point horizontal moving device includes a support frame, with horizontal moving frames arranged in parallel above the support frame. Each horizontal moving frame is equipped with two groups of winches installed above it. The horizontal moving frames are driven to slide on the top surface of the support frame by driving elements.

[0006] As a preferred embodiment of the above technical solution, the driving elements are double-piston-rod oil cylinders. The two ends of the double-piston-rod oil cylinders are respectively installed on the horizontal moving frames through a set of oil cylinder supports and oil cylinder pins. The middle part is fixed on the support frame through an oil cylinder mounting seat.

[0007] As a preferred embodiment of the above technical solution, the support frame is welded from a cross beam, a longitudinal beam, and a bottom plate.

[0008] As the preferred technical scheme of the above, two ends of the support frame are provided with mounting cavities below the transverse moving frame, and the double-piston rod oil cylinder is fixed in the mounting cavities.

[0009] As the preferred technical scheme of the above, a set of sling ascending limiters is installed in the mounting cavities corresponding to each set of winches.

[0010] As the preferred technical scheme of the above, a slide rail is fixed on the support frame, and the transverse moving frame is slidingly limited on the slide rail.
