Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, specifically to a ground rail structure for a continuous casting steel hydraulic shear traveling device. Background Technology

[0002] The hydraulic billet shear on the continuous casting steel production line is a key piece of equipment for achieving continuous cutting of hot billets. It moves along a ground rail via a slider on its base to make precise cuts. This ground rail is located below the billet, and it is prone to accumulating high-temperature oxides that fall off the billet, impurities generated by the spray cooling, and other sticky foreign objects. These accumulations can increase the equipment's moving resistance, cause vibration, or even jam, seriously affecting production efficiency and safety.

[0003] Currently, most ground rail systems use traditional rectangular or I-shaped cross-section tracks. A common solution to the problem of track debris accumulation is to install fixed scraper blades or scrapers on the moving equipment, relying on the equipment's movement to scrape away the debris. Chinese Patent Publication No. CN211142962U discloses a track cleaning device that uses a scraper blade in front of the track wheels to clean debris from the track. However, because this device lacks a scraper blade cleaning mechanism, residue can easily accumulate again on the scraper blade during the cleaning process, thus reducing the cleaning effectiveness.

[0004] Chinese Patent Publication No. CN206635713U discloses a railway track cleaning device. The device has a scraper cleaning device next to the scraper to clean the scraper. However, the device needs to be equipped with its own power supply and drive device, and its structure is relatively complex, making it difficult to be used in high-temperature environments.

Detailed Implementation

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art.

[0024] Example 1

[0025] like Figures 1-4 As shown, a ground rail structure for a continuous casting steel hydraulic shear traveling device includes a slider 1 and a rail 2. The rail 2 consists of a guide portion 201 with a triangular cross-section at the top and a load-bearing portion 202 with a rectangular cross-section at the bottom. The guide portion 201 and the load-bearing portion 202 are welded or integrally formed. The slider 1 straddles the guide portion 201 of the rail 2 through its internal groove and reciprocates along the length of the guide portion 201. A scraper assembly 3 is provided on the side of the slider 1 along the moving direction of the rail 2. The scraper assembly 3 includes components that interact with the slider 1. Block 1 is connected to a fixed plate 302 and a scraper 301 connected to the fixed plate 302. The fixed plate 302 and the scraper 301 are welded or integrally formed. One side of the scraper 301 is a scraping surface. The scraping surface of the scraper 301 is in close contact with the surface of one side of the guide part 201. The scraper 301 is made of high carbon steel. It utilizes its high hardness and high wear resistance to cope with the wear of high temperature oxides and extend the service life of the scraper 301. There are two sets of scraper assemblies 3, which are symmetrically arranged on both sides of the guide part 201.

[0026] This invention employs a triangular track structure, with scraper assemblies 3 symmetrically arranged on both sides of the guide section 201. This structure effectively cleans residue from the guide section 201 as the slider 1 moves. Utilizing the geometric properties of the triangular inclined plane, the scraped residue slides off the track along the inclined plane under gravity, solving the problem of secondary residue accumulation on the scraper 301. This solution has a simple structure, requires no additional power, can adapt to high-temperature environments, and can efficiently clean residue from the track.

[0027] The scraper 301 is machined into a continuous arc-shaped structure with an inwardly concave cross-section. This arc-shaped design not only ensures the scraping strength of the scraper 301, but also gives the scraper 301 a certain elastic deformation capability, enabling it to better adapt to the slight unevenness on the surface of the guide part 201. When encountering hard objects, it can undergo elastic deformation to overcome obstacles, effectively avoiding jamming or chipping, and enhancing reliability.

[0028] The fixing plate 302 has two through holes. After the internal hex bolt passes through the through holes, it is screwed into the pre-set threaded hole on the side wall of the slider 1, which can fix the scraper assembly 3 on the slider 1. This structure can realize the detachment of the scraper assembly 3, which is convenient for maintenance personnel to replace later.

[0029] Furthermore, the through hole is configured as a strip-shaped adjustment hole 3021. A pressure plate 4 is provided on the front side of the strip-shaped adjustment hole 3021. After the hexagon socket bolt passes through the pressure plate 4 and the strip-shaped adjustment hole 3021 in sequence, it is screwed into the pre-set threaded hole on the side wall of the slider 1, which can fix the scraper assembly 3 on the slider 1. This structure can realize the height adjustment of the scraper assembly 3. When the scraper 301 wears out after use, the maintenance personnel can loosen the bolts and use the adjustment margin of the strip-shaped adjustment hole 3021 to move the entire scraper assembly 3 up and down to the appropriate position, so that the scraping surface of the scraper 301 is in close contact with the surface of the guide part 201. Then the bolts are tightened again. This structure greatly extends the service life of the scraper assembly 3 and reduces the maintenance cost of the equipment.

[0030] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0031] Example 2

[0032] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, in order to further improve cleaning efficiency and prevent sticky residue from adhering to the scraper 301, this embodiment adds a pneumatic blowing structure.

[0033] Three independent closed air passages 5 are provided inside the guide section 201. The air passages 5 are arranged along the length of the guide section 201 and are: first air passage 501, second air passage 502, and third air passage 503. The air inlets of the three air passages 5 are located at the ends of the guide section 201, and their outlets are located at different heights on the side of the guide section 201. They are: the first air passage outlet 5011 and the third air passage outlet 5031 located at both ends of the guide section 201, and the second air passage outlet 5021 located in the middle of the guide section 201. There are two sets of air passage outlets, which are symmetrically arranged on both sides of the guide section 201.

[0034] On the inclined surface of the slider 1 that contacts the side of the guide 201, there is an elongated groove 6 at the same height as the air outlet of the air passage 5. The width of the elongated groove 6 is greater than or equal to the diameter of the air outlet of the air passage 5. The number of elongated grooves 6 on one side is the same as the number of air outlets of the air passage 5, namely: first elongated groove 601, second elongated groove 602, and third elongated groove 603. Inside the slider 1, there are two rising air passages 7. The rising air passages 7 are connected to the top of the elongated grooves 6. The air outlet 701 of the rising air passage 7 is located in the area above the side of the slider 1 where the scraper assembly 3 is located. The elongated grooves 6 and the rising air passages 7 are symmetrically arranged on both sides of the guide 201. A guide device is provided at the air outlet 701 to guide the airflow to the contact area between the scraper 301 and the guide 201.

[0035] One embodiment of the guiding device is an arc-shaped guide vane 8 made of stainless steel. The arc-shaped guide vane 8 is fixed above the air outlet 701 by welding or screws. The arc-shaped guide vane 8 is inclined downward and covers the front area of ​​the air outlet 701. It is used to guide the ejected high-pressure gas downward to the contact area between the scraper 301 and the guide part 201, which can improve the utilization rate of airflow and enhance the purging effect.

[0036] This invention employs a three-point layout for the air outlet of the air passage 5, enabling effective purging of the three key sections—the beginning, middle, and end—of the guide section 201. Simultaneously, the design of the elongated groove 6 transforms the purging process from "instantaneous ventilation" to "continuous segmental ventilation," increasing purging time and resulting in a more thorough purging. An external high-pressure air source is connected to the air inlet of the air passage 5 at the end of the guide section 201. When the slider 1 moves on the guide section 201, the air outlet of one of the air passages 5 falls into the coverage area of ​​its bottom elongated groove 6. At this time, the high-pressure gas flows sequentially through the air passage 5, the elongated groove 6, and the rising air passage 7, finally exiting from the air outlet 701. Under the action of the arc-shaped guide vane 8, it purges the scraper 301, effectively preventing secondary accumulation of sticky residue on the scraper 301 and achieving continuous cleaning.

[0037] Example 3

[0038] like Figure 2 , Figure 4 As shown, this embodiment is another implementation of the guiding device in Embodiment 2. The guiding device adopts a metal rigid tube 9, one end of which is sealed to the air outlet 701 through a pipe joint, and the other end extends to the contact area between the scraper 301 and the guide part 201 and is close to the top of the guide part 201. This structure can deliver the airflow to the target point in a more concentrated and precise manner, with less energy loss and better purging effect.

[0039] To further enhance the stability of the metal rigid pipe 9, a fixing rod 10 is added. One end of the fixing rod 10 is threadedly connected to the slider 1, and the other end is securely connected to the metal rigid pipe 9 via a pipe clamp. This structure ensures the long-term stability of the purging pipeline and prevents the purging effect from being affected by equipment movement.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
