Description

Technical Field

[0001] The utility model relates to a device for restoring a battery-powered vehicle to its proper track in a tunnel, which is mainly used to restore the battery-powered vehicle to the battery-powered vehicle track after the vehicle runs off the track in the tunnel. Background Art

[0002] With the rapid development of urban construction, urban rail transit has become an important means of travel for people. At present, shield construction is more and more widely used in tunnel construction. In shield tunneling, battery-powered locomotives are generally used as horizontal transportation tools for muck and materials in the tunnel. As a kind of rail transportation tool, battery-powered locomotives have always been the focus of safety management in shield construction due to characteristics such as long tunnels, large slopes, and heavy transport vehicles. As shown in the appendix Figure 1 When the battery-powered vehicle is running normally, the protruding flange inside the wheel of the battery-powered vehicle is stuck inside the rail of the battery-powered vehicle track to ensure that the battery-powered vehicle runs normally without derailing. As shown in the appendix Figure 2 When the battery-powered vehicle is running on a section with a small turning radius or passing through a turnout section, due to the change in the acting force between the wheel and the track at the turnout and curved track sections, the phenomenon of the battery-powered vehicle running off the track is very likely to occur. Once it runs off the track, only a jack can be used to lift the vehicle body, and then the method of manually moving the battery-powered vehicle onto the track for restoration is adopted. Due to the heavy weight of the battery-powered locomotive, when using a single jack for lifting, the force during the lifting process of the battery-powered vehicle is unstable, and it is easy to have a rollover accident, with a high risk. Moreover, due to the large weight of the battery-powered vehicle, it is difficult for manual labor to translate the vehicle body, and the restoration process is often slow and difficult. Once the restoration is not timely, the entire tunnel faces shutdown, which has a great impact on the normal construction and safety management at the site. Summary of the Utility Model

[0005] In the present utility model, when the piston rod of the lifting oil cylinder in the lifting device expands and contracts, it can drive the translation device to lift; the motor in the translation device can drive the rotation of the lead screw of the lead screw mechanism, and then drive the translation top plate to move through the lead screw mechanism. When the present utility model is in use, after the battery car derails, place the present utility model at the bottom of the battery car at a suitable position and fix it. Start the lifting oil cylinder, lift the battery car to a suitable height through the lifting oil cylinder, then start the motor of the translation device, drive the translation top plate to move the battery car horizontally to a suitable position through the lead screw mechanism, and finally slowly lower the lifting oil cylinder, and the battery car gets back on the track.
