Description

Technical Field

[0001] The utility model relates to the technical field of steel tapping machines, in particular to a lifting device for a steel tapping machine of a heating furnace. Background Art

[0002] The tapping machine (also known as a tapping machine or pusher) is a device used to push heated billets out of the heating furnace. It plays a vital role in the steel production process. The pusher is primarily responsible for pushing the heated billets out of the heating furnace. Its core motion is horizontal propulsion and retraction. To accommodate billets of varying sizes and positions, or for multi-layer heating furnaces, the tapping machine is equipped with a lifting device to adjust its height in special circumstances. This allows the tapping machine to push billets out of heating furnaces at different heights.

[0003] The patent with the current announcement number CN212620141U discloses a friction-type steel pusher, which includes a body plate, a lifting support plate located inside the body plate, and a push rod. The body plate has a rectangular structure, and a mounting bracket is welded to the bottom end surface of the body plate. The top surface of the mounting bracket and the two sides of the body plate are longitudinally threaded with hexagonal bolts. An inverted U-shaped protective cover is welded to the middle position of the top surface of the body plate. A mounting groove is provided inside the protective cover and located on the top surface of the body plate. The lifting support plate engages with the mounting groove. N groups of hydraulic support columns are symmetrically arranged between the bottom end surface of the mounting groove and the lifting support plate. Vertical plates are symmetrically welded to both sides of the middle of the top surface of the lifting support plate. An active roller is provided between the two groups of vertical plates. The friction-type steel pusher has an additional adjustment structure, which not only facilitates the normal movement of the push rod, but also has the function of adjusting the height to meet the needs of steel pushers of different heights.

[0004] However, the aforementioned tapping machine lifting device still has the following problem: when installing the tapping machine, it may be installed at an angle, which causes the push rod to have a certain inclination angle. Since this inclination angle cannot be adjusted during the lifting process, the push rod will be unstable when pushing the slab in the heating furnace. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a lifting device for a heating furnace steel-making machine, which can adjust the bearing plate of the bearing push rod on the steel-making machine horizontally at a certain angle, thereby improving the stability of the steel-making machine's pushing operation.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lifting device for a heating furnace steel-discharging machine, comprising a lifting device installed between a base and a load-bearing plate, the lifting device comprising a support assembly and four adjustment assemblies, the support assembly being located in the middle position between the base and the load-bearing plate, the four adjustment assemblies being respectively located at the four corners of the base and the load-bearing plate, and one corner of the load-bearing plate being connected to a horizontal observation assembly.

[0007] Furthermore, the support assembly includes a supporting hydraulic cylinder and a supporting ball, the bottom outer shell of the supporting hydraulic cylinder is fixedly connected to the middle position of the base, the telescopic end of the supporting hydraulic cylinder is fixedly connected to a bowl-shaped ball holder, the supporting ball is slidingly connected to the inner wall of the bowl-shaped ball holder, the side of the supporting ball away from the supporting hydraulic cylinder is fixedly connected to a supporting block, and the side of the supporting block away from the supporting ball is fixedly connected to the middle position of the bottom of the supporting plate.

[0008] Furthermore, the adjustment component includes an adjusting hydraulic cylinder and a top block, the bottom shell of the adjusting hydraulic cylinder is fixedly connected to one of the corners of the base, the telescopic end of the adjusting hydraulic cylinder is connected to the top block, and the side of the top block away from the adjusting hydraulic cylinder is against the bottom of one corner of the supporting plate.

[0009] Furthermore, the end of the top block away from the regulating hydraulic cylinder is spherical in design.

[0010] Furthermore, the top block is wrapped with a strong magnet inside, and is magnetically attracted to the supporting plate through the internal strong magnet.

[0011] Furthermore, the horizontal observation assembly includes two levels, and the two levels are respectively connected to two sides of the corners of one end of the supporting plate.

[0012] Furthermore, two communicating grooves are provided at both side corners of one end of the supporting plate, and the two levels are fixedly connected to the two grooves respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of heating furnace steel-discharging machine lifting device provides support for the load-bearing plate on the base through the support component in the middle. In conjunction with the adjustment components at the four corners, the load-bearing plate can be controlled for horizontal adjustment. In conjunction with the horizontal observation components at the corners, it can be intuitively observed whether the load-bearing plate has completed horizontal adjustment, ensuring that the steel-discharging machine pushing operation can be carried out stably.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figures 1 to 3 A lifting device for a heating furnace steel-discharging machine includes a lifting device installed between a base 1 and a loading plate 2. The lifting device includes a supporting assembly and four adjusting assemblies. The supporting assembly is located in the middle position between the base 1 and the loading plate 2. The four adjusting assemblies are respectively located at the four corners of the base 1 and the loading plate 2. One corner of the loading plate 2 is connected to a horizontal observation assembly.

[0021] like Figures 1 to 3 As shown, the lifting device of a heating furnace steel tapping machine in the present invention is similar in structure to the existing lifting device of a heating furnace steel tapping machine, such as a friction type steel tapping machine disclosed in the patent with publication number CN212620141U. The main improvement of the present invention is to ensure that the steel tapping machine can push the machine horizontally, such as Figures 1 to 3 As shown, when the heating furnace steel-discharging machine lifting device of the utility model is in use, the height of the supporting plate 2 can be adjusted on the base 1 by means of four adjusting components and the middle supporting component, and the different lifting heights of the four adjusting components are utilized. When the base 1 is not in a horizontal state, the state of the supporting plate 2 is adjusted to be horizontal, and the horizontal observation component can be used to intuitively observe whether the supporting plate 2 has completed the horizontal adjustment, ensuring that the ejection rod installed on the supporting plate 2 can smoothly and stably push the slab in the heating furnace out of the heating furnace, thereby improving the stability of pushing and tapping steel of the steel-discharging machine.

[0022] like Figures 1 to 3As shown, the support assembly includes a support hydraulic cylinder 3 and a support ball 4. The bottom shell of the support hydraulic cylinder 3 is fixedly connected to the middle position of the base 1. The telescopic end of the support hydraulic cylinder 3 is fixedly connected to a bowl-shaped ball holder 5. The support ball 4 is slidably connected to the inner wall of the bowl-shaped ball holder 5. The side of the support ball 4 away from the support hydraulic cylinder 3 is fixedly connected to a support block 6. The side of the support block 6 away from the support ball 4 is fixedly connected to the middle position of the bottom of the support plate 2. When the support hydraulic cylinder 3 is raised, the bowl-shaped ball holder 5 lifts the support ball 4, support block 6, and support plate 2 upward. When the support plate 2 is adjusted horizontally, the support ball 4 can rotate inside the bowl-shaped ball holder 5, thereby ensuring that the center of the support plate 2 remains substantially above the support hydraulic cylinder 3 and does not deviate significantly, thus providing a certain position limit for the support plate 2. The bowl-shaped ball holder 5 needs to be larger than a hemisphere to ensure that the support ball 4 does not detach from the bowl-shaped ball holder 5 while rotating inside the bowl-shaped ball holder 5, thereby improving the stability of the connection between the support hydraulic cylinder 3 and the support plate 2.

[0023] like Figures 1 to 3 As shown, the adjustment assembly includes an adjustment hydraulic cylinder 7 and a top block 8. The bottom shell of the adjustment hydraulic cylinder 7 is fixedly connected to one of the corners of the base 1. The telescopic end of the adjustment hydraulic cylinder 7 is connected to the top block 8. The side of the top block 8 away from the adjustment hydraulic cylinder 7 is against the bottom of one corner of the load-bearing plate 2. The adjustment hydraulic cylinder 7 can push one end of the load-bearing plate 2 upward through the top block 8, thereby changing the height of this corner of the load-bearing plate 2. In conjunction with the adjustment assemblies at the other three corners, the height of the four corners of the load-bearing plate 2 can be adjusted. In conjunction with the support assembly in the middle position, the load-bearing plate 2 is adjusted to a horizontal state, so that the steel-pushing rod installed on the load-bearing plate 2 can stabilize the steel-pushing operation.

[0024] like Figures 1 to 3 As shown, the end of the top block 8 away from the regulating hydraulic cylinder 7 is spherical. Setting the top block 8 to a spherical shape can make the top block 8 more stably lift the corners of the load-bearing plate 2 upwards.

[0025] like Figures 1 to 3 As shown, the top block 8 is wrapped with a strong magnet, and is magnetically attracted to the carrier plate 2 through the internal strong magnet. The strong magnet inside the top block 8 can magnetically fix the corners of the metal carrier plate 2 to a certain extent, making the adjusted carrier plate 2 more stable and less likely to shake during the steel pushing and tapping operations.

[0026] like Figures 1 to 3 As shown, the level observation assembly includes two levels 9, which are respectively connected to either side of a corner of one end of the support plate 2. By installing the levels 9 on both sides of the corner of the support plate 2, the leveling state of the support plate 2 can be observed through the cooperation of the two levels 9, and the leveling state of the support plate 2 can be conveniently and intuitively observed. The levels 9 are conventional products, such as the level rulers commonly used by carpenters.

[0027] like Figures 1 to 3 As shown, two communicating grooves 201 are provided at the two side corners of one end of the carrying plate 2, and the two level rulers 9 are respectively fixedly connected to the two grooves 201. The two level rulers 9 are installed in the grooves 201 to prevent the level rulers 9 from colliding with external objects and being damaged.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
