Description

Technical Field

[0001] This utility model relates to the technical field of furnace roller replacement tools, specifically to a multifunctional equipment replacement tool. Background Technology

[0002] Furnace rollers generally refer to furnace bottom rollers, which are rollers used in metallurgical furnaces and are mainly used for supporting, conveying and processing metal materials.

[0003] Furnace rollers are typically made of special high-temperature and wear-resistant materials to ensure stable operation in high-temperature and harsh environments. During the replacement of furnace rollers, the bearing housings and bearings installed on the rollers need to be removed, and the rollers are pulled out of the metallurgical furnace using a guide chain. Then, a crane and a replacement tool are used to replace the rollers. While existing replacement tools can achieve vertical balance using counterweights, they cannot achieve horizontal balance control. This often results in horizontal instability when moving the furnace rollers into the metallurgical furnace using the crane, affecting replacement efficiency. Furthermore, connecting and fixing the furnace rollers to the replacement tool is time-consuming, labor-intensive, inconvenient, and unsuitable for use. Therefore, it is necessary to design a multi-functional replacement tool to solve the aforementioned problems. Utility Model Content

[0004] Based on the above description, this utility model provides a multifunctional equipment replacement tool to solve the problems of traditional furnace roller replacement tools being unable to limit the horizontal angle and the time-consuming and laborious docking and fixing of the furnace roller with the replacement tool before replacement.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multifunctional equipment replacement tool includes a bracket, an adjustable counterweight, a roller fixing assembly and a furnace roller. One side of the bracket is provided with two slide rails, and the surface of the slide rails has an opening. A rectangular steel plate is provided on one side of the rectangular steel plate, and the surface of the slider has an opening. The slider is movably connected between the two slide rails. A pin is inserted between the opening and the opening. A support roller includes a concave frame and a roller. The concave frame is set on the rectangular steel plate, and the roller is movably connected to the concave frame.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, one side of the rectangular steel plate is provided with several protrusions, and each of the several protrusions is movably connected to a roller two along the horizontal longitudinal direction near the left and right sides of the rectangular steel plate.

[0008] Furthermore, the surface of the pin is provided with a gripping bar, which is located on the outside of the slide rail.

[0009] Furthermore, the surface of the slide rail has an opening three through it, and the diameter of the opening three is equal to that of the opening one and the opening two.

[0010] Furthermore, a baffle is provided on the outer side of the gripper, and a threaded rod is provided at the end of the pin away from the gripper, with a nut connected to the outer side of the threaded rod.

[0011] Furthermore, a buffer pad is provided on one side of the rectangular steel plate.

[0012] Furthermore, a reference plate is connected to one side of the rectangular steel plate.

[0013] Furthermore, the rectangular steel plate has a groove on the side near the slider one, and the concave frame has a slider two on one side, which is movably connected to the groove.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] 1. By connecting two slide rails to the bracket and connecting the rectangular steel plate to the two slide rails using a slider, and setting a pin between the slide rail and the slider, the operator can use the right side of the rectangular steel plate to contact the side of the external furnace body when using an external crane to replace the furnace rollers. Through the contact surface between the rectangular steel plate and the external furnace body, the angle of the replacement tool in the horizontal direction is restricted, preventing changes in the horizontal angle during furnace roller replacement that would affect the operation.

[0016] 2. By setting support rollers on the rectangular steel plate, when the operator needs to connect the furnace roller with the replacement tool, the operator can first place the furnace roller to be replaced on the support roller, then use roller two to slowly push the furnace roller towards the side of the fixed component, and finally use the fixed component to restrict and fix the furnace roller, which makes it easier for the operator to easily and quickly replace the furnace roller.

[0025] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0027] Example

[0028] Please refer to Figures 1-6 This embodiment provides a multi-functional equipment replacement tool, including a bracket 1, with lifting rods on both the left and right sides of the top surface of the bracket 1, an adjustable counterweight 2, a roller fixing assembly 3, and a furnace roller 4. The bottom surface of the bracket 1 is provided with two horizontal slide rails 11. An opening 111 is longitudinally opened on the surface of the slide rails 11 near the right side. A slider 51 is provided on the top surface of the rectangular steel plate 5 near the middle of the left side. An opening 2 511 with the same diameter as the opening 111 is opened on the surface of the slider 51. The slider 51 is movably connected between the two slide rails 11. A pin 6 is inserted between the opening 111 and the opening 2 511. The support roller 7 includes a concave frame 71 and a roller 72. The concave frame 71 is set on the rectangular steel plate 5, and the roller 72 is movably connected to the concave frame 71.

[0029] In this embodiment, the furnace roller 4 inside the external metallurgical furnace is first disassembled and extracted. Then, the furnace roller 4 to be replaced is slowly placed on roller 72. The furnace roller 4 is then moved closer to the roller fixing assembly 3 using roller 72, so that the roller end of the furnace roller 4 is inserted into the roller fixing assembly 3 and fixed. Next, an external overhead crane and hoisting rod are used to lift the replacement tool and furnace roller 4, and the vertical balance is adjusted and fixed using adjustable counterweight 2. Then, the overhead crane continues to move the replacement tool and furnace roller 4 horizontally, gradually integrating them with the metallurgical furnace. The furnace roller 4 to be replaced is slowly approached. During the approach, the right side of the rectangular steel plate 5 first contacts the surface of the metallurgical furnace, making the rectangular steel plate 5 parallel to the surface of the metallurgical furnace. The contact surface between the rectangular steel plate 5 and the metallurgical furnace achieves the effect of horizontal angle restriction. Then, the operator can pull out the pin 6 and use the overhead crane to continue to slowly move the replacement tool and the furnace roller 4 towards the metallurgical furnace. During the movement, the rectangular steel plate 5 moves within the two slide rails 11 via the slider 51 until the furnace roller 4 is pushed into the metallurgical furnace and installed and fixed.

[0030] As an optional implementation, one side of the rectangular steel plate 5 is provided with a plurality of protrusions 53, and each of the plurality of protrusions 53 is movably connected to rollers 8 along the horizontal longitudinal direction near the left and right sides of the rectangular steel plate 5.

[0031] In this embodiment, the replacement tool is placed on the ground so that roller 2 8 contacts the ground, and pressure is applied to push the replacement tool, which makes it easier for the staff to move the replacement tool.

[0032] As an alternative implementation, the surface of the pin 6 is provided with a gripping rod 61, which is located on the outside of the slide rail 11.

[0033] In this embodiment, the gripping rod 61 is gripped and pressure is applied outward, thereby causing the pin 6 to move outward within the opening 111 and the opening 511, making it convenient for the staff to operate the pin 6.

[0034] As an optional implementation, the surface of the slide rail 11 is provided with an opening three 112, the diameter of which is equal to that of opening one 111 and opening two 511.

[0035] In this embodiment, the rectangular steel plate 5 is moved by slider 51 so that opening 511 and opening 112 are brought closer to each other, and pin 6 is inserted between opening 511 and opening 112, thereby achieving the effect of restricting the slider 51 and the slide rail 11 after adjustment, and avoiding the phenomenon of slider 51 sliding randomly when the replacement tool is moved.

[0036] As an optional implementation, a baffle 611 is provided on the outer side of the gripper 61, and a threaded rod 62 is provided at the end of the pin 6 away from the gripper 61, with a nut 9 connected to the outer side of the threaded rod 62.

[0037] In this embodiment, the nut 9 is connected to the threaded rod 62, thereby using the baffle 611 and the nut 9 to fix the connection between the pin 6 and the slide rail 11, thus ensuring the stability of the pin 6.

[0038] As an optional implementation, a buffer pad 10 is provided on the right side of the rectangular steel plate 5.

[0039] In this embodiment, by setting a buffer pad 10 on the right side of the rectangular steel plate 5, the protective effect of the rectangular steel plate 5 on the external metallurgical furnace shell can be effectively achieved. This avoids the situation where the rectangular steel plate 5 is violently impacted by the metallurgical furnace and accidentally damaged when the replacement tool is adjusted by the overhead crane and the rectangular steel plate 5 comes into contact with the surface of the metallurgical furnace.

[0040] As an optional implementation, a reference plate 20 is connected to one side of the rectangular steel plate 5, and the reference plate 20 corresponds to the position of the furnace roller 4 and the roller fixing assembly 3.

[0041] In this embodiment, when the replacement tool is adjusted to a position close to the metallurgical furnace, the operator can determine the position of the rectangular steel plate 5 by observing the installation positions of the reference plate 20 and the furnace roller 4, which makes it easier for the operator to adjust the position of the rectangular steel plate 5.

[0042] As an optional implementation, the rectangular steel plate 5 has a groove 52 on the side near the slider 51, and the concave frame 71 has a slider 711 on one side, which is movably connected to the groove 52.

[0043] In this embodiment, during the sliding adjustment of the rectangular steel plate 5, the support roller 7 can slide under the position restriction of the roller fixing assembly 3, so as to avoid the obstruction phenomenon during the sliding adjustment of the rectangular steel plate 5.

[0044] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.
