Description

Technical Field

[0001] The utility model relates to the technical field of multifunctional overhead cranes, in particular to a connecting structure of a discharge pipe of a multifunctional overhead crane. Background Art

[0002] The multifunctional overhead crane includes a large car bridge frame, on which a trolley capable of moving left and right is installed. A material bin and an ash bin are fixed on the trolley. A material suction pipe device is installed on one side of the material bin. The material suction pipe device is used to suck high-temperature filling materials from the furnace pit and enter the material bin. A discharge pipe device is installed at the bottom of the material bin, and a discharge valve is installed at the bottom of the discharge pipe device. When discharging is required, the discharge valve is opened, and the discharge pipe device fills the filling materials into the furnace pit through the discharge pipe, which is convenient for transporting high-temperature filling materials, reduces dust dispersion, and is relatively environmentally friendly. It is commonly used in the pre-baking workshop of the carbon industry.

[0003] In the prior art, the discharge pipe device can be telescopic. When discharging, the discharge pipe device extends to facilitate discharging. When discharging is not required, the discharge pipe device contracts for easy storage and also for moving with the trolley. In use, the discharge pipe device is generally longer than the material suction pipe device and has a larger swing amplitude, which causes greater wear to the connection device between the discharge pipe and the discharge valve, and the maintenance takes a long time.

[0004] In the prior art, the seal of the discharge valve of the multifunctional overhead crane uses a 100-mm rubber gasket for sealing. After long-term use, it is found that the material temperature is too high, and the rubber gasket is extremely easy to be damaged and deformed, resulting in leakage of the discharge valve, which greatly affects the hygiene environment of the overhead crane and increases the difficulty of cleaning for employees. This problem has always been an incurable problem in the baking workshop, and the maintenance period is short.

[0005] Therefore, based on the above technical problems, those skilled in the art urgently need to develop a connecting structure of a discharge pipe of a multifunctional overhead crane. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a connecting structure of a discharge pipe of a multifunctional overhead crane.

[0013] One side of the connecting flange that mates with the discharge pipe is fixed with an extension pipe, and the extension pipe extends into the discharge pipe.

[0014] Further, the electric skateboard structure includes an electric slide valve and the slide valve flange located at its lower end;

[0015] The discharge pipe includes:

[0016] A lower pipe and a docking pipe connected to the upper end of the lower pipe;

[0017] The docking pipe is a tapered pipe fixed to the upper end of the lower pipe, and the tapered pipe is configured to have a structure with a gradually decreasing diameter from bottom to top;

[0021] Further, the outer diameter of the extension pipe is 300 mm and the length of the extension pipe is 200 mm;

[0022] The extension pipe passes through the discharge pipe flange and partially extends into the discharge pipe.

[0023] Further, a rubber gasket installation space is reserved between the connecting flange and the discharge pipe flange;
