Description

Technical Field

[0001] This utility model relates to the field of positioning tool technology, and in particular to a positioning and installation tool for the water inlet of a steel ladle. Background Technology

[0002] The inlet of a steel ladle needs to be positioned during installation. A Chinese patent with application number 202222587102.0 discloses a positioning device for accurately installing the inlet of a steel ladle, which includes a positioning rod 1, a positioning plate 3 fixedly installed along the side wall of the positioning rod 1, an inlet tray 2 fixedly installed on the surface of the positioning plate 3, a groove 4 provided in the inlet tray 2, a positioning baffle 5 fixedly connected to the side wall of the positioning plate 3, an auxiliary rod 6 fixedly installed at the bottom end of the positioning rod 1, and a support plate 7 installed on the positioning plate 3 and the auxiliary rod 6.

[0003] While the aforementioned technology achieves a certain degree of positioning effect, its inability to be adjusted in actual use prevents its application to water inlets of different diameters. Therefore, to address these shortcomings, we propose a ladle water inlet positioning and installation tool. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning and installation tool for the water inlet of a steel ladle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tool for positioning and installing a ladle inlet includes a receiving plate. Several linkage blocks are slidably provided on the west side of the receiving plate via a sliding groove. A positioning plate is installed on one side of the linkage block, and a connecting rod is installed on the other side of the linkage block. A control panel is rotatably provided on the upper side of the receiving plate via a spring-loaded assembly. The end of the connecting rod away from the linkage block passes through the top of the control panel. A mounting frame is fixed at the upper edge of the receiving plate. A control rod is rotatably installed in the middle of the upper end of the mounting frame. The lower end of the control rod is located inside the mounting frame and a locking frame is installed via a thread.

[0007] Preferably, the spring-loaded assembly includes a linkage shaft and a spring. The abutment plate has a mounting cavity in the middle. The linkage shaft is rotatably mounted in the mounting cavity. One end of the linkage shaft extends to the outside of the abutment plate and is connected to the control plate. The spring is mounted inside the mounting cavity and cooperates with the linkage shaft.

[0008] Preferably, a plurality of guide rods are circumferentially distributed at the upper edge of the mounting bracket, and the lower ends of the guide rods are slidably inserted into the locking bracket.

[0009] Preferably, the upper end of the guide rod extends above the mounting bracket, and a connecting cap is inserted into the upper end of the mounting bracket corresponding to the guide rod.

[0010] Preferably, the lower end of the connecting cap has a receiving cavity in the middle, and the upper end of the control lever is hexagonal prism-shaped and inserted into the receiving cavity.

[0011] Preferably, a linkage plate is provided on one side of the linkage block, and the end of the linkage plate away from the linkage block extends to the outside of the abutment plate, and the upper surface of the linkage plate is provided with scale lines.

[0012] Preferably, the control panel is provided with an inclined guide groove corresponding to the linkage rod, and the end of the locking frame corresponds to each slide groove.

[0013] The steel ladle inlet positioning and installation tool proposed in this utility model has the following advantages:

[0014] 1. In this utility model, under the action of the spring, the control panel drives the connecting rods to move away from each other. That is, the connecting rods drive the positioning plates to move away from each other through the linkage block until the positioning plates all abut against the inner wall of the water inlet hole. Then, the locking bracket fixes the connecting rods, thereby completing the connection between the water inlet and the tool. Then, under the action of the connecting cap, the operator can apply pressure to the tool through an external pressure device, thereby making the tool press the water inlet smoothly into the external water inlet seat brick, thus completing the positioning and installation of the water inlet. In summary, when using this solution, the setting of several positioning plates allows the operator to control the distance between the positioning plates, making the tool adaptable to water inlets of different diameters. The setting of the control panel facilitates the synchronous control of the movement of the positioning plates, allowing the operator to easily adjust the diameter to which the tool is adapted, thus solving the defect of traditional solutions that cannot adapt to water inlets of different diameters.

[0015] 2. The spring-loaded component in this invention allows for easy pushing of the positioning plates to fit against the inner wall of the external water inlet, thus ensuring a fixed connection between the water inlet and the tool for subsequent installation. The linkage plate not only improves the stability of the linkage block but also allows personnel to easily determine whether the positioning plates are concentric through the scale markings, thereby ensuring the positioning accuracy of this solution. The guide rod serves two purposes: firstly, it limits the locking frame, allowing it to move smoothly up and down to lock the linkage rod; secondly, it limits the connecting cap, allowing personnel to apply force to the mounting frame using external tools. Furthermore, the hexagonal prism at the top of the control rod allows for easy rotation using an external wrench to securely lock the linkage rod. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1-6 A tool for positioning and installing a ladle inlet includes a receiving plate 1. Several linkage blocks 2 are slidably provided on the west side of the receiving plate 1 via a sliding groove. A positioning plate 3 is installed on one side of the linkage block 2, and a linkage rod 4 is installed on the other side of the linkage block 2. A control panel 5 is rotatably provided on the upper side of the receiving plate 1 via a spring-loaded assembly. The end of the linkage rod 4 away from the linkage block 2 passes through the top of the control panel 5. A mounting frame 6 is fixed at the upper edge of the receiving plate 1. A control lever 7 is rotatably installed in the middle of the upper end of the mounting frame 6. The lower end of the control lever 7 is located inside the mounting frame 6 and a locking frame 8 is installed by threads.

[0026] Example 2

[0027] Reference Figure 1-6 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0028] The spring-loaded assembly includes a linkage shaft 9 and a spring 10. A mounting cavity is provided in the center of the abutment plate 1. The linkage shaft 9 is rotatably mounted within the mounting cavity. One end of the linkage shaft 9 extends to the outside of the abutment plate 1 and connects to the control panel 5. The spring 10 is mounted inside the mounting cavity and cooperates with the linkage shaft 9. The spring-loaded assembly allows the compressed spring 10 to drive the linkage shaft 9 to rotate after the locking frame 8 separates from the connecting rod 4. When the linkage shaft 9 rotates, it pushes the connecting rods 4 away from each other through the guide grooves on the control panel 5, thereby... Push each positioning plate 3 to fit against the inner wall of the inner hole of the external water inlet, thereby enabling the water inlet to be fixedly connected to this tool for subsequent installation; a linkage plate 13 is provided on one side of the linkage block 2, and the end of the linkage plate 13 away from the linkage block 2 extends to the outer side of the abutment plate 1. The upper surface of the linkage plate 13 is provided with scale lines. The setting of the linkage plate 13 not only improves the stability of the linkage block 2, but also makes it easy for personnel to judge whether each positioning plate 3 is concentric through the scale lines, thereby ensuring the positioning accuracy of this solution.

[0029] Several guide rods 11 are circumferentially distributed along the upper edge of the mounting frame 6. The lower ends of the guide rods 11 are slidably inserted into the locking frame 8, and the upper ends of the guide rods 11 extend above the mounting frame 6. A connecting cap 12 is inserted into the upper surface of the mounting frame 6 corresponding to the guide rods 11. A receiving cavity is provided in the middle of the lower end of the connecting cap 12. The upper end of the control rod 7 is hexagonal prism and is inserted into the receiving cavity. The guide rods 11 can limit the locking frame 8, allowing it to move smoothly up and down to lock the linkage rod 4. They can also limit the connecting cap 12, allowing personnel to apply force to the mounting frame 6 using external tools. At the same time, since the upper end of the control rod 7 is hexagonal prism, personnel can easily rotate it with an external wrench to securely lock the linkage rod 4. The control panel 5 has an inclined guide groove corresponding to the linkage rod 4. The end of the locking frame 8 corresponds to each groove. The guide groove facilitates the movement of the linkage rod 4 by the control panel 5.

[0030] Operating principle and advantages: In use, this invention is first inserted into the external water inlet, with each positioning plate 3 inserted into the inner hole of the water inlet, and the lower surface of the abutment plate 1 abutting against the end face of the water inlet. Then, the control lever 7 is rotated, and under the restriction of the guide rod 11, the control lever 7 drives the locking frame 8 to move only up and down. That is, the control lever 7 controls the locking frame 8 to disengage from the linkage rod 4. At this time, under the action of the spring 10, the linkage rod 4 is driven away from each other through the control plate 5, that is, the linkage rod 4 is driven away from each other through the linkage block 2. The positioning plates 3 are moved away from each other until they all abut against the inner wall of the water inlet hole. At this time, the operator rotates the control lever 7 in the opposite direction, which causes the locking bracket 8 to move down until it is firmly abutted against the upper end of the linkage rod 4. At this time, the linkage rod 4 cannot move, thus connecting the water inlet with the tool. The operator can then apply pressure to the tool through an external pressure device under the action of the connecting cap 12, thereby pressing the water inlet smoothly into the external water inlet seat brick, thus completing the positioning and installation of the water inlet.

[0031] Furthermore, after the water inlet is installed, the operator first uses the control lever 7 to separate the locking frame 8 from the linkage rod 4. At this time, the control panel 5 can be rotated in the opposite direction, causing the control panel 5 to move the linkage rod 4 closer together. During this process, the control panel 5 compresses the spring 10 through the linkage shaft 9. Finally, when the positioning plate 3 separates from the inner wall of the water inlet's inner hole, the tool can be smoothly pulled out of the water inlet. In summary, when using this solution, the setting of several positioning plates 3 allows the operator to control the distance between each positioning plate 3, making the tool adaptable to water inlets of different diameters. The setting of the control panel 5 facilitates the synchronous control of the movement of the positioning plates 3, allowing the operator to easily adjust the diameter to which the tool is suitable, thus solving the defect of traditional solutions that cannot adapt to water inlets of different diameters.

[0032] It should be further explained that the spring-loaded assembly allows the compressed spring 10 to drive the linkage shaft 9 to rotate after the locking frame 8 separates from the linkage rod 4. When the linkage shaft 9 rotates, it pushes the linkage rods 4 away from each other via the guide groove on the control panel 5. This pushes the positioning plates 3 to adhere to the inner wall of the external water inlet's inner hole, thus ensuring a fixed connection between the water inlet and the tool for subsequent installation. The linkage plate 13 not only improves the stability of the linkage block 2 but also allows personnel to easily determine whether the positioning plates 3 are aligned using the scale markings. The guide rod 11 serves two purposes: firstly, it limits the locking frame 8, allowing it to move smoothly up and down to lock the linkage rod 4; secondly, it limits the connecting cap 12, allowing personnel to apply force to the mounting frame 6 using external tools. Additionally, the hexagonal prism shape of the upper end of the control rod 7 allows for easy rotation with an external wrench to securely lock the linkage rod 4. The guide groove facilitates the movement of the linkage rod 4 by the control panel 5.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
