Description

Technical Field

[0001] The utility model belongs to the technical field of installing a small sleeve, and in particular relates to a protective device for installing a small sleeve. Background Art

[0002] During the installation of the small sleeve when the blast furnace is shut down, a ramming bar is used to hit the edge of the small sleeve to seal the contact surface with the middle sleeve.

[0003] When installing the small sleeve, the tamping rod hits the edge of the small sleeve. The small sleeve is made of pure copper and has a soft texture. The width of this edge is 151mm. When hitting the edge of the small sleeve with the tamping rod, if it hits the smooth contact surface on the inner edge of the small sleeve, it will cause poor contact after the blowpipe is installed, causing air leakage. In severe cases, the blowpipe will have to be stopped and replaced again. Utility Model Content

[0004] The utility model aims to provide a protective device for small-set installation.

[0005] The utility model solves the technical problem by adopting the following technical solution: a protective device for installing a small sleeve, comprising a circular plate, a plurality of plug-ins evenly distributed are arranged on the top of the circular plate, the end of the small sleeve is installed through the plug-ins, a pipe is welded on the bottom of the circular plate, and an L-shaped groove is arranged inside the pipe.

[0006] Specifically, the insert is a thin steel bar bent into an obtuse angle.

[0007] Specifically, the bottom of the circular plate is an impact point to fix the small sleeve and the middle sleeve.

[0008] Specifically, an L-shaped plug-in is installed in the L-shaped card slot, and the protective device is separated from the small cover through the L-shaped plug-in.

[0009] The utility model has the following beneficial effects: effectively eliminating the risk of damaging the smooth contact surface during the installation of the small sleeve, while increasing the impact points during the installation, and greatly improving the efficiency of installing the small sleeve.

[0014] The utility model will now be further described in detail with reference to the accompanying drawings.

[0015] like Figure 1-3 As shown, a protective device for small sleeve installation includes a circular plate 1, a plurality of evenly distributed plug-ins 2 are provided on the top of the circular plate 1, and the end of the small sleeve 7 is installed through the plug-ins 2. A pipe 3 is welded to the bottom of the circular plate 1, and an L-shaped groove 4 is provided inside the pipe 3.

[0016] The insert 2 is a thin steel bar bent into an obtuse angle.

[0017] The bottom of the circular plate 1 is an impact point 5 to fix the small sleeve 7 to the middle sleeve.

[0018] An L-shaped plug-in unit 6 is installed in the L-shaped slot 4 , and the protective device is separated from the small cover 7 by the L-shaped plug-in unit 6 .

[0019] The use of the utility model:

[0020] When working, insert the plug-in 2 on the protective device into the inner hole of the small sleeve, weld three thin steel bars on a circular iron plate as a hard connection with elastic force, and when installing the small sleeve, the tamping bar hits the impact point 5 to fix the small sleeve and the middle sleeve. The bottom of the circular plate 1 is an iron pipe with an L-shaped slot 4. After the small sleeve 7 is installed, insert the L-shaped plug-in 6 into the iron pipe of the L-shaped slot 4 to remove the protective device.
