Description

Wear-resistant gap bridge device for steel rolling

Technical Field

The utility model relates to the technical field of steel rolling machinery, in particular to a wear-resistant gap bridge device for steel rolling.

Background

In the steel rolling production line, the bridge device is a rolled piece transmission channel erected between adjacent devices. At present, the bridge used in most steel mill production lines is formed by directly splicing steel plates, and although the bridge can meet production requirements, for a high-speed moving area of a rolled piece, the bridge can be quickly worn due to sliding friction between the rolled piece and the bridge, so that wear grooves are formed in the bottom and the side wall of the bridge, and steel stacking is easy to occur when the rolled piece runs to the high-speed moving area. Meanwhile, the abrasion of the bridge also leads to shortened service life of the bridge and increased production cost.

Disclosure of Invention

The technical scheme for solving the problems is as follows: a wear-resistant gap bridge device for rolling steel comprises a guide groove, a carrier roller body and a carrier roller frame;

the guide slot comprises two bridge passing side plates and a bridge passing bottom plate, the two bridge passing side plates are respectively and fixedly connected to two sides of the bridge passing bottom plate, two side bridge passing side plates are respectively connected with a carrier roller frame, and two ends of the carrier roller body are respectively and rotatably arranged on the carrier roller frames at two sides through rotating shafts.

Further, one side of the carrier roller body is provided with an oil filling hole, and the oil filling hole is connected with rolling line oil gas.

Further, still include cooling device, cooling device includes first cooling tube, second cooling tube and third cooling tube, and first cooling tube and second cooling tube set up along the bridge curb plate respectively, the third cooling tube sets up along the bearing roller body, and the both ends of third cooling tube communicate with first cooling tube and second cooling tube respectively, be equipped with a plurality of water spray holes on first cooling tube, second cooling tube and the third cooling tube respectively.

Further, the bridge floor is provided with a mounting groove strip, the upper part of the carrier roller body is arranged in the mounting groove strip, and a gap is formed between the carrier roller body and the edge of the mounting groove strip.

Further, lifting lugs are arranged on the bridge side plates.

The utility model has the beneficial effects that:

the utility model provides a wear-resistant gap bridge device for steel rolling, which has the advantages of simple structure, reasonable design, strong practicability and convenient field use; the manufacturing is simple and the maintenance is easy; the abrasion of the bridge passing device is effectively reduced through the carrier roller body and the cooling device.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model;

FIG. 2 is a schematic view of a guide slot structure;

in the figure: the device comprises a 1-bridge passing side plate, a 2-bridge passing bottom plate, a 3-carrier roller body, a 4-carrier roller frame, 5-mounting groove strips, 6-first cooling pipes, 7-third cooling pipes and 8-lifting lugs.

Detailed Description

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art in a specific case.

As shown in the figure, the abrasion-resistant gap bridge device for rolling steel comprises a guide groove, a carrier roller body, a carrier roller frame and a cooling device;

the guide slot comprises two bridge passing side plates and a bridge passing bottom plate, the two bridge passing side plates are respectively and fixedly connected to two sides of the bridge passing bottom plate, a roller frame is respectively connected to the bridge passing side plates on two sides, the roller frame is connected with the bridge passing side plates through a plurality of bolts, two ends of a roller body are respectively and rotatably mounted on the roller frames on two sides through rotating shafts, the rotating shafts are connected with the roller frames through bearings, mounting groove strips are arranged on the bridge passing bottom plate, the upper portions of the roller body are arranged in the mounting groove strips, and gaps are formed between the roller body and the edges of the mounting groove strips.

One side of the carrier roller body is provided with an oil filling hole, and the oil filling hole is connected with rolling line oil gas.

The cooling device comprises a first cooling pipe, a second cooling pipe and a third cooling pipe, wherein the first cooling pipe and the second cooling pipe are respectively arranged along the bridge side plate, the third cooling pipe is arranged along the carrier roller body, two ends of the third cooling pipe are respectively communicated with the first cooling pipe and the second cooling pipe, and a plurality of water spraying holes are respectively formed in the first cooling pipe, the second cooling pipe and the third cooling pipe.
