[0015] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0016] The present invention will be further described below by way of embodiments, but the scope of the present invention is not limited thereto.

[0017] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0018] like Figure 1 As shown, a cover plate for lifting hole of gun mud in front of furnace comprises a rectangular frame, a front cover plate 1, a rear cover plate 2, a front cylinder 3 and a rear cylinder 4. The rectangular frame comprises a left frame 5, a front frame 6, a right frame 7 and a rear frame 8. The front cover plate and the rear cover plate are located in the rectangular frame. The cylinder body of the front cylinder is fixed on the front frame and the end of its telescopic rod is fixedly connected to the front cover plate. The cylinder body of the rear cylinder is fixed on the rear frame and the end of its telescopic rod is fixedly connected to the rear cover plate. The front cylinder and the rear cylinder respectively drive the corresponding front cover plate and the rear cover plate to merge to close the lifting hole or to move away from each other to open the lifting hole.

[0019] During installation, the left frame, the front frame, the right frame and the rear frame are fixed around the hanging opening on the top of the dust cover, and when the front cover plate and the rear cover plate are closed, the hanging opening can be completely blocked.

[0020] The front and rear cover plates are controlled by the cylinder to move away from or towards each other to open or close the lifting port, thereby eliminating the need to lift the cover plate to the ground and then lift it back in the prior art, thereby improving efficiency and saving manpower.

[0021] Angle irons 9 are installed at the four corners of the front cover plate and the rear cover plate, and a fixed shaft 10 is fixedly installed on the angle iron. Wheels 11 are rotatably installed on the fixed shaft, and the wheels are correspondingly placed on the left frame and the right frame.

[0022] The angle irons are fixed to the front and rear cover plates by welding, and only eight angle irons are needed to assemble the wheels to the left and right frames. The structure is simple, material is saved, and the manufacturing cost is low.

[0023] A first connecting plate 12 is fixedly mounted on the upper surface of the front cover plate, a second connecting plate 13 is fixedly mounted on the front frame, a cylinder body of the front cylinder is fixedly mounted on the second connecting plate, and a piston rod of the front cylinder is fixedly connected to the first connecting plate.

[0024] The third connecting plate 14 is fixedly mounted on the upper surface of the rear cover plate, the fourth connecting plate 15 is fixedly mounted on the rear frame, the cylinder body of the rear cylinder is fixed on the third connecting plate, and the piston rod of the rear cylinder is fixedly connected to the fourth connecting plate.

[0025] The left frame, front frame, right frame and rear frame are all C-shaped steel with the notch facing outward.

[0026] The front cover plate and the rear cover plate are provided with upward flanges around their peripheries.

[0027] The middle parts of the front cover plate and the rear cover plate are provided with a plurality of reinforcing ribs.

[0028] Since the front and rear cover plates are relatively thin and are connected to the left and right frames through angle irons and wheels, the height of the front and rear cover plates is lower than the upper end surface of the rectangular frame, which is not conducive to the installation of the cylinder. The design of the first to fourth connecting plates facilitates the installation of the front and rear cylinders.

[0029] Flanging and reinforcing ribs can improve the strength of the front and rear cover plates, eliminating the need for heavy steel plates and saving costs.

[0030] The upper end surfaces of the left frame and the right frame are provided with guide grooves, the length direction of the guide grooves is the front-back direction, and the depth of the wheels in the guide grooves is 1 / 4.

[0031] The guide groove can ensure the guiding and limiting functions and ensure the stability of operation.

[0032] In the above scheme, the wheels can be of the smallest size, which is sufficient for rolling and has the lowest cost, while the wheels with guide grooves require a larger wheel diameter.

[0033] Correspondingly, the C-shaped steels of the left and right frames can be designed with the notches upward. This design places greater demands on the wheels and is more expensive.

[0034] It should be noted that the embodiments described above are only used to explain the utility model and do not constitute any limitation to the utility model. The utility model is described by reference to typical embodiments, but it should be understood that the words used therein are descriptive and explanatory words, rather than restrictive words. The utility model can be modified as specified within the scope of the claims of the utility model, and the utility model can be revised without departing from the scope and spirit of the utility model. Although the utility model described therein involves specific methods, materials and embodiments, it does not mean that the utility model is limited to the specific examples disclosed therein. On the contrary, the utility model can be extended to all other methods and applications with the same functions.
