Description

Technical Field

[0001] This invention relates to the technical field of hydraulic equipment for continuous casting machines, and in particular to a replacement device for hydraulic equipment of continuous casting machines. Background Technology

[0002] The primary power source for hydraulic equipment operation is a hydraulic pump driven by an electric motor. The pump pressurizes the hydraulic oil, which is then converted into mechanical energy by actuators, driving the working parts in linear reciprocating or rotary motion. In industrial production, the power unit of the hydraulic system—the pump motor—is a crucial component.

[0003] Hydraulic equipment requires replacement and maintenance after prolonged use. A common replacement method is to use lifting equipment such as electric hoists to remove the hydraulic equipment. However, due to the design of the hydraulic station in a continuous casting machine, the existing electric hoists are installed off-center from the lifting center of gravity of the oil pump motor or hydraulic pump. This can easily lead to tilted or angled lifting when using electric hoists to lift the oil pump motor or hydraulic pump, posing a significant safety risk during the lifting operation. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a hydraulic equipment replacement device for a continuous casting machine, which solves the problem that when using an electric hoist to replace hydraulic equipment in the prior art, the phenomenon of skewed pulling and tilting easily occurs, thus posing a significant safety risk.

[0005] To achieve the above and other related objectives, the present invention provides a hydraulic equipment replacement device for a continuous casting machine. The replacement device includes a support frame, an adjustment component, a traveling trolley, and a lifting component. The support frame is disposed on a foundation plane on which the hydraulic equipment is installed. The adjustment component is used to adjust the support frame to keep it horizontal. The traveling trolley is movably disposed on the support frame. The lifting component is mounted on the traveling trolley and is used to lift the hydraulic equipment.

[0006] Optionally, the support frame includes multiple columns and a movable plane. The columns are vertically arranged on the base plane, the movable plane is horizontally fixed at the top of the columns, and the traveling trolley is movably arranged on the movable plane.

[0007] The lifting component is positioned in the middle of the traveling trolley, and a clearance space is provided on the guide rail plane to allow space for the movement of the traveling trolley and the lifting component.

[0008] Optionally, the traveling trolley includes a trolley frame, a plurality of rollers rotatably mounted on the trolley frame, and a drive assembly. The drive assembly is used to drive the rollers to roll, and the rollers roll in conjunction with the support frame. The lifting assembly is mounted on the trolley frame.

[0009] Optionally, the support frame is provided with a guide rail, and the rollers are rolled and engaged on the guide rail.

[0010] Optionally, the drive assembly includes a geared motor and a drive shaft. The geared motor is fixedly mounted on the trolley frame, and the output end of the geared motor is coaxially and fixedly connected to the drive shaft. At least one of the rollers is coaxially and fixedly connected to the drive shaft.

[0011] Optionally, the lifting assembly includes a lifting motor, a worm gear reducer, and a lifting rod. The lifting motor is coaxially and fixedly connected to the input shaft of the worm gear reducer. The lifting rod is vertically and coaxially inserted through the worm wheel of the worm gear reducer. A threaded hole is formed at the center of the worm wheel of the worm gear reducer, and a slot is formed on the side wall of the threaded hole. The lifting rod is a lead screw, which is threaded into the threaded hole. A retaining strip is provided on the side wall of the lifting rod along its length, and the retaining strip can be engaged in the slot. The hydraulic device can be fixedly connected to the bottom end of the lifting rod.

[0012] Optionally, the bottom of the lifting rod is provided with a hanging hole for hanging the hydraulic equipment.

[0013] Optionally, the adjustment assembly is disposed on each of the columns. The adjustment assembly includes a screw, a nut slider, and a rotating assembly. The nut slider is threadedly connected to the screw. The rotating assembly is used to drive the screw to rotate around its own axis. The column is configured as a hollow structure. One end of the screw passes vertically through the bottom of the column and is inserted into the column. The other end of the screw abuts against the base plane. The end of the column away from the moving plane is fixedly connected to the nut slider.

[0014] Optionally, the rotating assembly includes a rotating block, which is coaxially fixedly connected to one end of the screw near the base plane, and an insertion hole is provided on the side wall of the rotating block.

[0015] Optionally, the replacement device further includes a controller and a remote controller, the controller being electrically connected to the traveling trolley and the lifting assembly, and the remote controller being electrically connected to the controller.

[0016] In summary, the beneficial effects of the present invention are as follows:

[0017] By setting up a traveling trolley and lifting assembly, when hydraulic equipment needs to be replaced, the support frame is placed on the foundation plane. The support frame is adjusted using the adjusting assembly to ensure it remains level. Then, the traveling trolley is hoisted onto the support frame, allowing it to move. Since the lifting assembly is mounted on the traveling trolley, it moves along with the trolley. When the lifting assembly reaches the hydraulic equipment, tools are used to detach it from the foundation plane, separating it from the base. The hydraulic equipment is then connected to the lifting assembly, which lifts it. The traveling trolley then moves the hydraulic equipment to an open area. Finally, using the lifting assembly, the hydraulic equipment is lowered onto a push-pull trolley pre-positioned in the open area. The push-pull trolley moves the disassembled hydraulic equipment to a designated area, thus completing the disassembly. Similarly, new hydraulic equipment can be placed on a push-pull trolley, and the lifting assembly and traveling trolley can be used to reinstall it onto the foundation plane. This makes the entire replacement process simpler, saves time and effort, and is safer. Attached Figure Description

[0020] The following reference Figures 1 to 2 This invention describes a hydraulic equipment changing device for a continuous casting machine. In the description of this embodiment, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature, that is, include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. When a feature "includes or contains" one or more of the features it encompasses, unless otherwise specifically described, this indicates that other features are not excluded and may be further included.

[0021] Unless otherwise expressly specified and limited, the terms "set up," "install," "connect," "link," "fix," and "couple" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] like Figure 1 and Figure 2 As shown, this embodiment of the invention provides a hydraulic equipment replacement device for a continuous casting machine. The replacement device includes a support frame 1, an adjusting component 3, a traveling trolley 2, and a lifting component 4. The support frame 1 is mounted on a foundation plane where the hydraulic equipment is installed. The adjusting component 3 is used to adjust the support frame 1 to keep it horizontal. The traveling trolley 2 is movably mounted on the support frame 1. The lifting component 4 is mounted on the traveling trolley 2 and is used to lift the hydraulic equipment.

[0025] When replacing hydraulic equipment, support frame 1 is placed on the foundation plane. Adjustment component 3 is used to level support frame 1 on the foundation plane. Then, the traveling trolley 2 is hoisted onto support frame 1, allowing it to move. Since lifting component 4 is mounted on traveling trolley 2, it moves along with the trolley. When lifting component 4 reaches the hydraulic equipment, tools are used to detach it from the foundation plane. The hydraulic equipment is then connected to lifting component 4, and lifted using lifting component 4. The traveling trolley 2 then moves the hydraulic equipment to an open area. Finally, using lifting component 4, the hydraulic equipment is lowered onto a push-pull trolley previously positioned in the open area. The push-pull trolley moves the disassembled hydraulic equipment to a designated area, thus completing the disassembly of the hydraulic equipment. Similarly, the new hydraulic equipment can be placed on the push trolley, and then reinstalled onto the foundation plane using the lifting assembly 4 and the traveling trolley 2. By using the traveling trolley 2 and the lifting assembly 4, the entire replacement process is relatively simple, time-saving, labor-saving, and safe.

[0026] Furthermore, the support frame 1 includes multiple uprights 11 and a movable plane 12. The uprights 11 are vertically arranged on the foundation plane. The movable plane 12 is horizontally fixed at the top of the uprights 11. The traveling trolley 2 is movable on the movable plane 12. The support frame 1 uses a combination of uprights 11 and movable plane 12, resulting in a relatively simple structure. Optionally, four uprights 11 are provided and respectively located at the four corners of the movable plane 12, thereby making the overall placement of the support frame 1 more stable.

[0027] Furthermore, the lifting component 4 is positioned in the middle of the traveling trolley 2. A clearance space 14 is provided on the moving plane 12 to allow space for the movement of the traveling trolley 2 and the lifting component 4. Positioning the lifting component 4 in the middle of the traveling trolley 2 ensures more even force distribution, thereby preventing the traveling trolley 2 from tipping over. Additionally, the structure is relatively simple by employing the aforementioned support frame 1.

[0028] Optionally, the movable plane 12 includes two profiles spaced apart to form a clearance space 14.

[0029] Of course, the lifting component 4 can also be set on one side of the traveling vehicle 2, without reserving space 14.

[0030] Furthermore, the traveling trolley 2 includes a trolley frame 21, multiple rollers 22 rotatably mounted on the trolley frame 21, and a drive assembly. The drive assembly drives the rollers 22 to roll, and the rollers 22 roll in conjunction with the support frame 1. A lifting assembly 4 is mounted on the trolley frame 21. By driving the rollers 22 to roll through the drive assembly, the traveling trolley 2 can move on the support frame 1, resulting in a simple structure.

[0031] Furthermore, the drive assembly includes a geared motor 23 and a drive shaft 24. The geared motor 23 is fixedly mounted on the trolley frame 21. The output end of the geared motor 23 is coaxially and fixedly connected to the drive shaft 24. At least one roller 22 is coaxially and fixedly connected to the drive shaft 24. When the trolley 2 needs to move, the geared motor 23 is turned on, which drives the drive shaft 24 to rotate. The rotation of the drive shaft 24 in turn drives the roller 22 to rotate coaxially, thereby realizing the movement of the trolley 2.

[0032] Optionally, the trolley frame 21 is formed by three profiles fixedly connected, and the trolley frame 21 has an overall I-beam structure. Four rollers 22 are provided, symmetrically arranged at the four corners of the trolley frame 21. The two ends of the drive shaft 24 are coaxially fixedly connected to two of the rollers 22 that are symmetrically arranged along the direction of travel. The geared motor 23 drives the drive shaft 24 to rotate, thereby causing the two rollers 22 to rotate synchronously, thus realizing the movement of the traveling trolley 2.

[0033] Furthermore, a guide rail 13 is provided on the support frame 1, and rollers 22 roll in cooperation with the guide rail 13. Specifically, the guide rail 13 is horizontally fixed on the moving plane 12. By setting the guide rail 13, the direction of movement of the traveling trolley 2 is limited. When the traveling trolley 2 is moved directly above the reducer, the guide rail 13 plays a certain positioning role.

[0034] Furthermore, the lifting assembly 4 includes a lifting motor 41, a worm gear reducer 42, and a lifting rod 43. The lifting motor 41 is coaxially and fixedly connected to the input shaft of the worm gear reducer 42. The lifting rod 43 is vertically and coaxially inserted through the worm wheel of the worm gear reducer 42. A threaded hole is formed at the center of the worm wheel of the worm gear reducer 42, and a slot is formed on the side wall of the threaded hole. The lifting rod 43 is a lead screw, and the lifting rod 43 is threaded into the threaded hole. A retaining strip is provided on the side wall of the lifting rod 43 along its own length direction, and the retaining strip can be engaged in the slot. A hydraulic device can be fixedly connected to the bottom end of the lifting rod 43. Optionally, the lifting motor 41 and the worm gear reducer 42 are fixedly mounted on the trolley frame 21.

[0035] When lifting the hydraulic equipment using lifting assembly 4, the lifting assembly 4 moves to be directly above the hydraulic equipment via the traveling trolley 2, at which point the lifting rod 43 is also directly above the hydraulic equipment. The lifting rod 43 is fixedly connected to the hydraulic equipment by adjusting its height. The hydraulic equipment can be lifted by adjusting the height of the lifting rod 43. The principle for adjusting the height of the lifting rod 43 is as follows: Turning on the lifting motor 41 causes the lifting unit to drive the worm gear reducer 42 to rotate. As the worm gear reducer 42 rotates, because the lifting rod 43 is threadedly connected to the worm gear reducer 42, and because the lifting rod 43 does not rotate around its own axis under the action of the locking strip and slot, according to the screw nut principle, the lifting rod 43 will move up and down as the worm gear reducer 42 rotates, thus achieving the purpose of adjusting the lifting rod 43. The lifting assembly 4 described above has a simple structure and is easy to operate.

[0036] Furthermore, a hanging hole 44 is provided at the bottom of the lifting rod 43 for hanging hydraulic equipment. Using a hook, one end of the hook is hung on the hanging ring of the hydraulic equipment, and the other end is hung in the hanging hole 44, thereby achieving a fixed connection between the hydraulic equipment and the lifting rod 43. The structure is simple and the operation is convenient.

[0037] Furthermore, the adjustment assembly 3 is disposed on each column 11. The adjustment assembly 3 includes a screw 31, a nut slider 32, and a rotating assembly. The nut slider 32 is threadedly connected to the screw 31. The rotating assembly is used to drive the screw 31 to rotate around its own axis. The column 11 is configured as a hollow structure, with one end of the screw 31 vertically passing through the bottom of the column 11, and the other end of the screw 31 abutting against the base plane. The end of the column 11 away from the moving plane 12 is fixedly connected to the nut slider 32.

[0038] When the base plane is uneven, the support frame 1 will also be uneven when placed on the base plane, requiring leveling. The screw 31 is driven to rotate by a rotating assembly. The rotation of the screw 31 causes the nut slider 32 to move along the length of the screw 31, thereby adjusting the height of the columns 11. By continuously adjusting the height of each column 11, the support frame 1 can be leveled.

[0039] Optionally, when the columns 11 are set to four and are respectively located at the four corners of the movable plane 12, the adjustment component 3 can also be set only on the two columns 11 on the same side.

[0040] Furthermore, the rotating assembly includes a rotating block 33, which is coaxially fixedly connected to one end of the screw 31 near the base plane. An insertion hole is provided on the side wall of the rotating block 33. When it is necessary to rotate the screw 31, an external rocker arm is inserted into the insertion hole, and manually rotating the rocker arm will rotate the screw 31.

[0041] Furthermore, the replacement device also includes a controller and a remote control. The controller is electrically connected to the traveling trolley 2 and the lifting assembly 4, and the remote control is also electrically connected to the controller. Remote control of the traveling trolley 2 and the lifting assembly 4 can be achieved via the remote control, making it more convenient. Specifically, the controller is electrically connected to the geared motor 23 and the lifting motor 41.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
