Summary of the invention

The utility model object is to solve existing YDT-50 type hydraulic top thruster can not be applicable to the problem that QU50 shaped steel rail is constructed, and provides a kind of the fixing device that YDT-50 type hydraulic top thruster coordinates with QU50 shaped steel rail.

The fixing device that the YDT-50 type hydraulic top thruster that the utility model provides coordinates with QU50 shaped steel rail, comprise Split type casing, upper voussoir assembly and lower wedge block assembly, an add-on module is respectively set up in the both sides, Split type casing lower ending opening place of this fixing device, this add-on module comprises a module voussoir and a module block, the rear surface of module voussoir and QU50 shaped steel rail inside face coincide, the inside face of the front surface of module voussoir and QU100 shaped steel rail coincide, and is respectively fixed with a module block at the front end of module voussoir.

Gross thickness after described two module voussoirs and QU50 shaped steel rail are fitted respectively and the consistency of thickness of QU100 shaped steel rail.Be that module voussoir is to make according to the thickness difference between QU100 shaped steel rail and UY50 shaped steel rail, meet the requirement of YDT-50 type hydraulic top thruster mechanical grip part to rail thickness, can make the construction that matches with QU50 shaped steel rail of YDT-50 type hydraulic top thruster mechanical grip part.

Each YDT-50 type hydraulic top thruster is equipped with two add-on modules, its objective is the mechanical grip part of YDT-50 type hydraulic top thruster is adapted with UY50 shaped steel rail, thereby the comformability that improves YDT-50 type hydraulic top thruster, reduces the number of times of having bad luck and make sliding rail beam.

advantage of the present utility model and good effect

This apparatus structure is simple, easy to make, cost is lower, and for improving, YDT-50 type hydraulic top thruster is significant to the applicability of QU50 model rail, can reduce the construction cost in main equipment installation process.
