Abstract
The present invention discloses a shield segment reaction frame for a test. The shield segment reaction frame comprises a reaction frame body in a self-balancing closed annular shape, the reaction frame body consists of a plurality of module units which are successively connected, each module unit including more than one steel structures and one fixed plate located on the steel structures, and the steel structures are connected with the fixed plate, wherein the fixed plate is provided with a T-shaped groove which is the same as the reaction frame body in the axial direction and is configured to fix a load cylinder. When the external diameter of the shield segment is changed, the number of the steel structures in the module unit or the number of the module units in the reaction frame body is regulated to adapt shield segments having different external diameters. When the ring height of the shield segment is changed, the load cylinder is moved to an appropriate position for fixation along the T-shaped groove of the fixed plate so that the shield segment is loaded to test. The shield segment reaction frame for a test provided by the invention is capable of testing shield segments having a plurality of dimensions so that the condition of frequently replacing reaction frames is avoided and the cost of manufacturing a plurality of reaction frames is reduced. Moreover, the integrated multi-loop shield segment reaction frame provided by the invention is capable of doing the test of the multi-loop shield segment, therefore the test efficiency is improved and the assembly is simple and easy.

In order to solve the technical problem, the technical solution used in the present invention is: a kind of test shield duct piece reaction frame, comprise the reaction frame body in self-equilibrating closed ring, described reaction frame body is connected to form successively by multiple modular unit, each modular unit comprises steel structure and 1 fixed head be positioned on steel structure of more than 1 that links together, and fixed head is provided with reaction frame body shaft to the identical T-slot for fixing load cylinder.When the external diameter change of shield duct piece, the quantity of modular unit in the quantity of steel structure or reaction frame body in adjustment module unit, to adapt to the different shield duct piece of external diameter.When the ring High variation of shield duct piece, load cylinder is moved to suitable position along the T-slot of fixed head and fixes, shield duct piece can be loaded and test.
Further, described modular unit comprises left steel structure, right steel structure and fixed head, and left steel structure and right steel structure link together, and fixed head is fixed on the junction of left steel structure and right steel structure.
Further, described fixed head is identical with the height of left steel structure, right steel structure, and left steel structure is identical with the thickness degree of right steel structure.
Further, described modular unit comprises left steel structure, middle steel structure, right steel structure and fixed head, and left steel structure, middle steel structure, right steel structure are connected in turn, and fixed head is fixed on middle steel structure.
Further, fixed head is identical with the height of left steel structure, middle steel structure, right steel structure, and the thickness of left steel structure, middle steel structure, right steel structure is identical.
Further, described reaction frame body is connected to form successively by 12 modular units.
Further, multiple reaction frame body couples together up and down and forms many rings shield duct piece reaction frame.Many rings shield duct piece reaction frame can do the test of many rings shield duct piece simultaneously, improves test efficiency.
Further, the bottom of described modular unit is provided with leg, convenient fixing.
Beneficial effect of the present invention: test shield duct piece reaction frame body of the present invention is made up of multiple modular unit, each modular unit comprises steel structure and 1 fixed head be positioned on steel structure of more than 1 that links together, and fixed head is provided with reaction frame body shaft to the identical T-slot for fixing load cylinder.When the external diameter change of shield duct piece, the quantity of modular unit in the quantity of steel structure or reaction frame body in adjustment module unit, to adapt to the different shield duct piece of external diameter.When the ring High variation of shield duct piece, load cylinder is moved to suitable position along the T-slot of fixed head and fixes, shield duct piece can be loaded and test.Test shield duct piece reaction frame of the present invention can test the shield duct piece of sizes, avoids the situation frequently changing reaction frame, reduces the expense making multiple reaction frame.And many rings shield duct piece reaction frame of composition can do the test of many rings shield duct piece, improves test efficiency, and assembles simple and convenient simultaneously.
