Description
Technical Field
The utility model belongs to shield structure equipment field, in particular to prevent oblique shield structure machine platform truck.
Background
With the increasing of tunnel engineering at home and abroad, the shield machine is being widely used as a sharp tool for tunnel construction.
The whole shield machine consists of a main machine and a trolley marshalling. In the tunneling process of the shield tunneling machine, oil, water, gas, electricity and other power sources are provided by a trolley marshalling. Typically, a dolly consist consists of 5 to 8 trailers. When the number of auxiliary equipment required to be installed on the trolley is increased, the number of the trolley marshalling sections can reach more than 10 sections.
The shield machine trolley is generally of a portal structure, and the middle space of a portal is used as an advancing channel of a shield machine material transport locomotive. The left side and the right side of the portal frame are provided with shield machine auxiliary equipment storage platforms for arranging various power sources and other auxiliary equipment.
As various auxiliary equipment is arranged on the shield machine trolley, the shield machine trolley has more quantity, different types and larger overall weight. When various devices are placed on platforms on the left side and the right side of the trolley, the complete balance of the bearing on the left side and the right side of the trolley cannot be achieved. Due to the existence of the unbalanced weight phenomenon, the stability of the trolley is inevitably poor in the advancing process.
Due to the presence of the equipment unbalance, the trolley is inevitably deviated to a certain degree in the left and right directions. And because the equipment installation position on each trolley is different, the deflection direction and the deflection degree of each trolley are different, and the phenomenon that the front trolley and the rear trolley are twisted with each other can be generated in severe cases, so that the field personnel operation and the material transportation are influenced.
The current methods for solving the phenomenon mainly comprise: 1. various devices on the two sides of the shield machine trolley are arranged in a balanced manner as much as possible, but the load balance on the left side and the right side of the trolley cannot be completely realized, and the shield machine trolley still has a left-right deflection trend; 2. when the deflection of the shield machine trolley is excessive, the deviation is corrected by adopting a manual or mechanical method, the method is time-consuming and labor-consuming, and is influenced by space limitation, a plurality of tools cannot be effectively used, so that the adjustment is very difficult, and the potential safety hazard of operation also exists.
