Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, specifically to a hydraulic cover device for a steel mixing vehicle. Background Technology

[0002] like Figure 1 As shown, the molten iron mixing car cover device is used to cover the molten iron during transportation, which can significantly reduce heat loss during transportation and waiting, and effectively reduce the emission of pollutants such as smoke and dust into the atmosphere. Particulate matter often accumulates at the feed inlet of the molten iron mixing car. This particulate matter can prevent the cover and feed inlet from closing completely, increasing heat loss and pollutant emissions. Therefore, the particulate matter at the feed inlet needs to be removed before covering the car. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic capping device for a mixed iron car, comprising a tank body, a sealing cap located above the tank body, and further comprising a transverse telescopic arm and a longitudinal telescopic arm. The transverse telescopic arm is connected to the sealing cap and is used to control the transverse movement of the sealing cap. The longitudinal telescopic arm controls the longitudinal movement of the transverse telescopic arm. An air blowing pipe is installed on the sealing cap and rotates around its center. The air blowing pipe is driven by a drive mechanism and corresponds to the feed inlet of the tank body, and is used to blow particles from the edge of the feed inlet.

[0005] Preferably, the drive mechanism includes an independent cylinder, the cylinder body of which is fixedly mounted on the end of the transverse telescopic arm facing the feed inlet by a bracket, the telescopic end of the independent cylinder is hinged to a connecting rod, and the other end of the connecting rod is rotatably connected to the air blowing pipe.

[0006] Preferably, a rotating column is provided at the center of the top of the sealing cover, one end of the air blowing pipe is fixed on the rotating column, the air inlet end of the air blowing pipe is located at the connection between the air blowing pipe and the connecting rod, the air blowing pipe is a rigid metal pipe, and its air inlet end is connected to an external air source through a high-temperature resistant hose.

[0007] Preferably, the air blowing pipe is designed to avoid obstruction between itself and the inlet of the tank.

[0008] Preferably, the maximum rotation angle of the rotating column is designed to be 170 degrees, the airflow of the blowing pipe can sweep across the entire feed inlet end face, and the blowing pipe does not interfere with the lateral telescopic arm.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] In this utility model, a hydraulic capping device for molten iron mixing cars uses an air blowing pipe driven by an independent cylinder. This pipe can rotate up to 170 degrees around a rotating column, allowing the airflow to sweep across the entire feed inlet end face, removing dust, slag, and other particles from the edges. This prevents the cap from not closing properly with the feed inlet due to debris accumulation, and reduces heat loss and dust emissions during molten iron transportation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The hydraulic cover device for mixed-rail vehicles provided by this utility model mainly includes the following core components (refer to Figure 1):

[0017] Tank 1: Used to hold molten iron, with a feed inlet at the top.

[0018] Sealing cap 2: Covers the tank body 1, and its position is adjusted by the horizontal telescopic arm 3 and the vertical telescopic arm 4.

[0019] Lateral telescopic arm 3: One end is fixedly connected to the sealing cover 2, and the other end is connected to the longitudinal telescopic arm 4, used to control the lateral movement (such as left and right translation) of the sealing cover 2.

[0020] Longitudinal telescopic arm 4: The bottom is connected to the external support structure (such as the frame of a steel car), and the top drives the horizontal telescopic arm 3 to move up and down, so as to realize the lifting and lowering of the sealing cover 2.

[0021] Air blowing pipe 5: Installed at the top center of the sealing cover 2, it rotates around the central axis through a drive mechanism and is used to blow away particulate matter from the edge of the feed inlet of the tank 1.

[0022] II. Working principle of the air blowing pipe drive mechanism (refer to Figures 2 and 3)

[0023] Drive mechanism components:

[0024] Independent cylinder 9: The cylinder body is fixedly installed on the end of the horizontal telescopic arm 3 near the feed port via bracket 10, serving as a power source.

[0025] Connecting rod 8: One end is hinged to the telescopic end of the independent cylinder 9, and the other end is rotatably connected to the air blowing pipe 5 (the end of the connecting rod 8 is located in the through hole and sleeved on the air blowing pipe 5).

[0026] Rotating column 7: fixed to the center of the top of the sealing cover 2, one end of the air blowing pipe 5 is welded and fixed to the outside of the rotating column 7, and the other end extends towards the feed port.

[0027] Working principle

[0028] When it is necessary to purge the feed inlet, the piston rod of the independent cylinder 9 extends, pushing the connecting rod 8 to move away from the feed inlet.

[0029] The connecting rod 8 drives the air blowing pipe 5 to rotate around the rotating column 7. Since the air blowing pipe 5 and the connecting rod 8 are rotatably connected, its rotation angle is controlled by the cylinder stroke.

[0030] The maximum rotation angle of the air blowing pipe 5 is designed to be 170 degrees to ensure that the airflow covers the entire feed inlet end face (as shown in Figure 1) while avoiding interference with the transverse telescopic arm 3.

[0031] The air blowing pipe 5 is a rigid metal pipe (such as a stainless steel pipe), and its air inlet end 6 is located at the connection with the connecting rod 8. It is connected to an external air source (such as a compressed air pipeline) through a high-temperature resistant hose. The hose can adapt to the displacement when the air blowing pipe 5 rotates.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
