The billet in the heating furnace is placed on the outgoing roller table through a lifting device, and the driving motor is started to convey the billet.

[0003] However, it is found in actual use that the bearing seat of the outgoing roller table close to the heating furnace is baked by high temperature for a long time. Even if the bearing seat is a water-cooled bearing seat, it is still impossible to avoid the bearings on the furnace door side of the outgoing roller table from often being locked. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a heat insulation device for a bearing seat of an outgoing roller table, which can protect the bearing seat on the furnace door side of the outgoing roller table, avoid being baked by high temperature for a long time, and reduce the failure rate of the bearings.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is a heat insulation device for a bearing seat of an outgoing roller table, which includes a heat insulation cover and a hydraulic cylinder.

[0006] The heat insulation cover is in an L shape; a part of the heat insulation cover is vertically arranged between the bearing seat and the furnace door of the heating furnace, and the other part is above the bearing seat; one or more heat insulation sleeve seats are hinged at the bottom of the heat insulation cover.

[0007] The hydraulic cylinder is arranged on one side of the outgoing roller table, and one end of the hydraulic cylinder is hinged with a hydraulic cylinder seat; the piston rod of the hydraulic cylinder is hinged with a connecting part; the connecting part is fixed to the inner bottom of the heat insulation cover.

[0008] Preferably, the width of the heat insulation cover is greater than the width of two bearing seats of the outgoing roller table; the hydraulic cylinder is arranged between two outgoing roller tables; the connecting part is fixed to the middle of the inner bottom of the heat insulation cover.

[0009] Preferably, a cooling pipe is installed inside the heat insulation cover; the cooling pipe is arranged in a serpentine shape.

[0010] The heat insulation device for a bearing seat of an outgoing roller table of the utility model has the following advantages compared with the prior art:

[0011] (1) The heat of the heating furnace can be isolated through the heat insulation cover, and the bearing seat can be avoided from being baked for a long time.

[0012] (2) Adding cooling water pipes inside the heat insulation cover can not only reduce the roasting of the bearing seat, but also ensure the service life of the heat insulation cover itself;

[0013] (3) The heat insulation cover can be automatically flipped by the hydraulic cylinder to prevent the heat insulation cover from affecting the tapping;

[0014] (3) Simple design, easy to use, and low manufacturing cost. Description of the Drawings

[0016] Figure 2 It is a partial cross-sectional view of the side of the heat insulation cover;

[0017] Figure 3 It is a schematic structural diagram of the present utility model in front of the heating furnace. Detailed Embodiment

[0018] The following further describes the present utility model in conjunction with the drawings and specific embodiments.

[0019] As Figure 1-2 shown, a heat insulation device for the bearing seat of the discharging roller table includes a heat insulation cover 1 and a hydraulic cylinder 2,

[0020] The heat insulation sleeve 1 is in an L shape; one part of the heat insulation sleeve 1 is vertically arranged between the bearing seat 31 and the furnace door 5 of the heating furnace, and the other part is above the bearing seat 31 to isolate the heat of the heating furnace; one or more heat insulation sleeve seats 11 are hinged at the bottom of the heat insulation sleeve 1, so that the heat insulation sleeve 1 can rotate around the hinge point, facilitating the placement of the section steel in the heating furnace on the discharging roller table 3 and preventing the section steel from colliding with the heat insulation sleeve 1;

[0021] The hydraulic cylinder 2 is arranged on one side of the discharging roller table 3, and one end of the hydraulic cylinder 2 is hinged with a hydraulic cylinder seat 21; the piston rod of the hydraulic cylinder 2 is hinged with a connecting part 22; the connecting part 22 is fixed to the inner bottom of the heat insulation sleeve 1. By starting the hydraulic cylinder 2, the piston rod of the hydraulic cylinder 2 extends, causing the connecting part 22 and the heat insulation sleeve 1 to rotate around the hinge point of the heat insulation sleeve seat 11, so as to automatically flip the heat insulation sleeve 1 and prevent the heat insulation sleeve 1 from affecting the tapping.

[0022] In this embodiment, the width of the heat insulation sleeve 1 is greater than the width of the bearing seats 31 of the two discharging roller tables 3; the hydraulic cylinder 2 is arranged between the two discharging roller tables 3; the connecting part 22 is fixed to the middle of the inner bottom of the heat insulation sleeve 1, and one heat insulation sleeve 1 can protect the bearing seats 31 on the furnace door 5 side of the two discharging roller tables 3.

[0024] The usage method of the utility model: when the heating furnace is heating, introduce cooling water into the cooling pipe 12 to insulate the bearing seat 31. After the furnace door 5 of the heating furnace is opened, start the hydraulic cylinder 2, the piston rod of the hydraulic cylinder 2 extends, so that the connecting part 22 and the heat insulation sleeve 1 rotate around the hinge of the heat insulation sleeve seat 11, thereby turning over the heat insulation sleeve 1. The steel lifting device 4 extends to take out the section steel in the heating furnace and lift it onto the discharging roller table 3. At the same time, start the motors of several discharging roller tables 3 to convey the section steel through the discharging roller table 3.
