In order to ensure the integrity, the stability and the installation convenience of the whole structure, the supporting ring is of a multi-petal structure, and each petal of the supporting ring is simultaneously connected with a plurality of steel plates.

Preferably, the supporting ring is fixed on the supporting rod through a screw, the screw is coaxial with the supporting rod, and the screw and the supporting ring are fixed relatively.

In order to enhance the rigidity of the floor, a reinforcing piece is fixedly connected to the middle position of the bottom of each steel plate.

Preferably, the reinforcing part is angle steel, and the angle steel is parallel to a tangent line of the supporting ring.

In order to facilitate the adjustment of the height and the level of the steel plate, the support rod is provided with a flat square notch for adjustment.

In order to prevent operation and maintenance personnel from slipping on the steel plate, the upper surface of the steel plate is of a pattern structure.

Has the advantages that: compare the level that traditional A-frame can't adjust every steel sheet and highly whole condition that easily appears the wrong limit, and the field installation is inconvenient, the utility model discloses a change floor assembly structure, the rotation support pole makes its adjust from top to bottom in the nut, simultaneously with the radial rotation of trunnion ring cooperation, realize on-the-spot quick installation and adjustment, the trunnion ring has improved the wholeness in addition, and bearing capacity is strong, and the trunnion ring couples the polylith steel sheet, strengthens the fastness when guaranteeing the levelness, and is both practical and pleasing to the eye.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the drawings, but the present invention is not limited to these embodiments, and the modifications made to the present invention are also within the scope of the claims of the present invention without departing from the principles of the present invention.

Example 1

As shown in fig. 1 and 2, a floor structure of a hydraulic generator comprises 12 circular fan-shaped steel plates 1 which are spliced with each other, a connecting piece 2 and a supporting mechanism are arranged at the bottom of each steel plate 1, the connecting piece 2 is an angle steel, one side of the angle steel is welded on a pit lining 3, the other side of the angle steel is fixedly connected on the steel plate 1 through a screw 7-2, the bottom of each steel plate 1 is fixedly connected on a supporting ring 4, the supporting mechanism comprises a supporting rod 5, the bottom of the supporting rod 5 is in threaded connection with a nut 6, the nut 6 is welded on the upper plane of a top cover of the hydraulic generator or an upper frame of the generator, a threaded hole is arranged at the center of the top of the supporting rod 5, a screw 7-1 is fixedly connected at the bottom of the supporting ring 4, an extending part of the screw 7-1 is connected in the threaded hole, and the supporting rod 5 can rotate on the screw 7-1 in the radial direction, the upper surface of the supporting ring 4 supports the steel plate 1.

The trunnion ring 4 is 4 lamella structures, 3 are connected simultaneously to each lamella of trunnion ring 4 steel sheet 1 guarantees overall structure's stability, installs 3 simultaneously steel sheet 1 is convenient for operate, reduces steel sheet 1 is to the degree of difficulty of overall regulation.

Every the intermediate position fixedly connected with reinforcement 8 of 1 bottom of steel sheet, reinforcement 8 with the tangent line of filler ring 4 is parallel, reinforcement 8 adopts the angle steel structure, and the field manufacturing is simple, and is with low costs and structural strength is big, can strengthen the rigidity on floor, promotes the bearing capacity and avoids sinking or even collapsing because of fortune dimension personnel and maintenance tool equipment overweight.
