Installation device for subway vehicle equipment cabinet

technical field

The utility model relates to subway vehicle equipment, in particular to a subway vehicle equipment cabinet installation device, which belongs to the technical field of urban rail vehicles.

Background technique

In order to meet the normal operation requirements of the subway, equipment cabinets are installed on both sides of the carriage end. The existing equipment cabinet installation method adopts on-site drilling and opening, and the equipment cabinet is directly installed on the aluminum honeycomb floor of the vehicle, which requires pre-embedded pads on the aluminum honeycomb floor, the equipment cabinet structure frame and the aluminum Floor cloth should be laid between the floors, and aluminum honeycomb floor support adjustment pads and corrugated floors should be installed between the vehicle support beams and pre-embedded pads, and then the equipment cabinet structure frame should be fixed to the pre-built under the aluminum honeycomb floor by fasteners. Buried on the pad. This installation method is difficult to ensure the accuracy of equipment installation, and once the installation holes on the floor are drilled, the installation size cannot be adjusted, and there are many complicated installation structures, which is also not conducive to vehicle weight reduction.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a subway vehicle equipment cabinet installation device that can adjust the installation size, is simple, reliable and convenient to install, reduces the weight of the local structure, and reduces the cost.

The purpose of this utility model is achieved through the following technical solutions, a subway vehicle equipment cabinet installation device, an iron floor is laid on the vehicle support beam, and the equipment cabinet support mounting seat is fixed on the iron floor; the equipment cabinet support mounting seat is an inverted U Shaped structure, with a horizontal oblong hole in the middle, and a through hole at the end bend; the fastening nut is drawn into the anti-rotation groove through the through hole at the end bend of the equipment cabinet support mounting seat; the anti-rotation groove is a horizontal hole in the middle. The positive U-shaped structure of the oblong hole, the anti-rotation groove is fixed on the lower part of the equipment cabinet support mounting base, and the horizontal oblong hole on the anti-rotation groove corresponds to the horizontal oblong hole on the equipment cabinet support mounting base; the fastening bolt passes through the equipment cabinet The longitudinal oblong holes on the structural frame and the transverse oblong holes on the supporting mounting base of the equipment cabinet are screwed into the fastening nuts for fastening.

The beneficial effect of the utility model is that the installation and operation are simple, no on-site drilling is required, the horizontal and vertical adjustments can be made during installation, the structural parts at the connection are reduced, the production cost is reduced, the weight is reduced, and the practicability is strong.

detailed description

In order to make the purpose of the invention, technical solutions and advantages of the utility model clearer, the technical solutions of the utility model are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are the embodiment of the utility model. Some of the embodiments are novel, but not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Referring to the accompanying drawings, the installation device for the subway vehicle equipment cabinet of the present utility model includes an equipment cabinet structure frame 1, a hexagonal fastening bolt 2, a hexagonal fastening nut 3, and a vehicle support beam 4, and the equipment cabinet structure frame 1 is installed with a longitudinal Long round hole, the iron floor 7 is laid on the vehicle support beam 1, and the equipment cabinet support mounting seat 5 is fixed on the iron floor 7. The equipment cabinet support mounting seat 5 is an inverted U-shaped structure, with a horizontal long round hole in the middle, and the bending part at the end Open the hole; the fastening nut 3 is drawn into the anti-rotation groove 6 through the through hole at the bending part of the end of the equipment cabinet support mounting seat 5; the anti-rotation groove 6 is a positive U-shaped structure with a transverse oblong hole in the middle, and the anti-rotation groove 6 is fixed on the lower part of the support mounting base 5 of the equipment cabinet, and the horizontal oblong hole on the anti-rotation groove 6 corresponds to the horizontal oblong hole on the support mounting base 5 of the equipment cabinet; the fastening bolt 2 passes through the The longitudinal oblong holes and the transverse oblong holes on the support mount 5 of the equipment cabinet are screwed into the fastening nuts 3 for fastening.

Lay iron floor 7 above the vehicle support beam 4, weld the equipment cabinet support mounting seat 5 on the iron floor 7, and the anti-rotation groove 6 is buckled under the equipment cabinet support mounting seat 5 and will be welded together in advance.

Referring to Figure 3, the equipment cabinet support mounting base 5 and the anti-rotation groove 6 are provided with horizontal oblong holes, and the equipment cabinet structure frame 1 is provided with longitudinal oblong holes, so that both the vertical and horizontal directions are oblong holes, so it can be installed during installation. Horizontal and vertical local adjustments.

Referring to Fig. 2, a through hole is opened at the bending part of the end of the equipment cabinet support mounting base 5. When installing, first put the hexagonal fastening nut 3 into the anti-rotation groove 6 through the through hole of the equipment cabinet support mounting base 5, After alignment, turn the hexagonal fastening bolt 2 so that the bolt and nut can be tightened. The anti-rotation groove 6 is a U-shaped structure, and the hexagonal fastening nut 3 cannot rotate in the anti-rotation groove 6. The width w of the anti-rotation groove 6 is larger than the dimension s of the nut 3, but smaller than the dimension e of the nut 3, that is, s< w<e, so it can prevent rotation and is conducive to reliable installation.
