Description

Technical Field

[0001] The utility model belongs to the field of metallurgy, and particularly relates to a slag skimming device for molten metal. Background Art

[0002] Most of the existing slag skimming devices are installed on the walking beams similar to double-girder bridge cranes under the main traveling crane in the same workshop. Although they have a large operating range, this type of structure depends on the double-girder bridge crane spanning the workshop, occupying a large horizontal area and creating an obstruction in the workshop, hindering the normal movement and operation of the main traveling crane. Especially when the relevant metallurgical equipment is concentrated in a certain area of the workshop and frequent hoisting operations by the traveling crane are required, without the working time of the traveling crane slag skimmer, if the traveling crane slag skimmer needs to work, the hoisting work of the traveling crane must stop, which not only affects work efficiency but also poses a safety hazard.

[0015] The technical solution of the utility model will be described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments.

[0016] As shown in Figure 1 , a single-beam walking slag removal device includes a fixedly arranged walking beam device 6, a walking device 5 that moves along the walking beam device 6, a moving assembly connected to the walking device 5, and a slag removal mechanism 1 installed at the end of the moving assembly.

[0017] The walking beam device 6 is supported by a single column 7 or two or more columns 7. In this embodiment, the base part of the walking beam device 6 and the column 7 are made of steel structures, or integrally cast reinforced concrete, etc.

[0018] The walking device 5 includes a main body, an electric control box and a hydraulic station installed on the top of the main body, and also includes walking wheels 5-1 installed at the bottom of the main body. The walking wheels 5-1 are driven by a motor and cooperate with the walking track on the walking beam device 6.

[0019] As an alternative implementation, the hydraulic station can also be arranged on the ground and connected by means of pulleys or cables.

[0020] Furthermore, to prevent the walking device 5 from tipping under the action of unilateral load, the walking device 5 further includes a limit wheel installed on the body. The limit wheel is located on the side or below the walking beam device 6 and cooperates with the walking beam device 6.

[0021] In this embodiment, the limit wheel includes a first limit wheel 5-2 and a second limit wheel 5-3. The rotation axis of the first limit wheel 5-2 is vertically arranged and cooperates with the support track on the walking beam device 6 near the slag scraping mechanism 1. The rotation axis of the second limit wheel 5-3 is horizontally arranged and extends into and cooperates with the support hook groove on the other side of the walking beam device 6.

[0022] As an alternative embodiment, the limit wheel can also adopt other structural forms. For example, inclined surfaces are provided on both sides of the walking beam device 6, support tracks are laid on the inclined surfaces, and the limit wheels on both sides cooperate with the support tracks.

[0023] Furthermore, the moving assembly includes a cantilever beam 3, a moving mechanism 4, and a lifting mechanism 2. The cantilever beam 3 is perpendicular to the walking beam device 6, and one end is fixedly connected to the body of the walking device 5. The moving mechanism 4 travels along the cantilever beam 3. The lifting mechanism 2 is installed on the moving mechanism 4, and the slag scraping mechanism 1 is installed on the lifting end of the lifting mechanism 2. Through the walking device 5, the moving mechanism 4, and the lifting mechanism 2, the slag scraping mechanism 1 can be driven to achieve arbitrary movement in three-dimensional space.

[0024] Specifically, the moving mechanism 4 can be directly driven by hydraulic pressure or a motor, or the relative movement between the moving mechanism 4 and the cantilever beam 3 can be achieved through a gear and rack mechanism. The lifting mechanism 2 can be driven by a hydraulic cylinder, or an electric push rod or other mechanisms can be used for driving.

[0025] The moving assembly can also adopt other structural forms, such as a SCARA robot arm, a parallel manipulator, etc.

[0026] The slag scraping mechanism 1 includes a transmission box and a slag rake located at the bottom of the transmission box.

[0027] This device can be independently arranged in the factory building and can be arranged at a height position lower than that of the crane, which is suitable for slag scraping operations in local areas and can avoid interference with equipment such as cranes at the same time.

[0028] It should be noted that for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
