Technical Field
[0001] The utility model relates to the technical field of instrument maintenance tools, in particular to a metallurgical electrical instrument maintenance device. Background Technique
[0002] An electrical instrument is a device used to measure, control, protect, and monitor the operating state of a power system and various electrical parameters and signals. It is widely used, covering multiple fields such as metallurgy, industry, scientific research, transportation, medical treatment, and telecommunications. In the metallurgical industry, instruments such as flow meters and thermometers are commonly used, which are also common electrical instruments on the market. At the same time, due to factors such as the service life or the use environment of these instruments, they occasionally get damaged. Therefore, whenever they are damaged, they need to be repaired, and during the repair process, the front cover or the rear shell of the instrument needs to be removed to repair and maintain the internal components. Therefore, a special clamping device is used to clamp it to facilitate people's disassembly and repair operations.
[0003] However, the common operation method is for manual workers to clamp it with a clamping device, and then free their hands to use disassembly tools for disassembly operations. However, due to different electrical instruments having different shapes, some are round and some are square, and most common maintenance clamping tools can only clamp one type of instrument, which has certain limitations in use and a narrow application range.
[0004] Therefore, it is necessary to provide a new metallurgical electrical instrument maintenance device to solve the above technical problems. Summary of the Invention

[0008] Further, two groups of sliding rods are arranged in parallel on both sides of the transverse screw. The two ends of the sliding rods are respectively fixedly connected to the two ends of the U-shaped frame. The transverse movement seat is slidably sleeved on the sliding rods, and the sliding rods limit the horizontal movement of the transverse movement seat along the transverse screw.

Specific embodiments
[0021] Now, the present utility model will be further described in detail with reference to the accompanying drawings.
[0022] As Figure 1-6 shown, a metallurgical electrical instrument maintenance device includes a maintenance table 1, a first concave seat 2 fixedly installed on the maintenance table 1, and a second concave seat 3 movably connected to the maintenance table 1 through a horizontal movement mechanism; clamping assemblies are provided on the upper parts of the first concave seat 2 and the second concave seat 3, and the clamping assemblies include a horizontally arranged rotating rod 4. One end of the rotating rod 4 is connected to a first motor. A disc 5 is fixedly installed on the rotating rod 4. The outer wall of the disc 5 is provided with a first slot 6 and a second slot 9 at intervals at a certain angle. The included angle between the first slot 6 and the second slot 9 is 90°. A first insert bar 7 is installed in the first slot 6, and an arc-shaped clamping bar 8 is fixedly connected to the end of the first insert bar 7. A second insert bar 10 is installed in the second slot 9, and a C-shaped clamping bar 11 is fixedly connected to the end of the second insert bar 10. The first motor drives the rotating rod 4 and the disc 5 to rotate, and the first insert bar 7 and the second insert bar 10 rotate with the disc 5.
[0023] The horizontal moving mechanism includes a U-shaped frame 12, which is fixedly installed on the maintenance table 1. A transverse screw 13 is rotatably installed inside the U-shaped frame 12. One end of the transverse screw 13 is connected to the second motor, and the second motor is fixedly installed at the end of the U-shaped frame 12. A transverse moving seat 14 is threadedly installed on the transverse screw 13. The top of the transverse moving seat 14 is fixedly connected to the bottom of the second concave seat 3. The second motor drives the transverse screw 13 to rotate, thereby driving the transverse moving seat 14 and the second concave seat 3 to move horizontally along the transverse screw 13. Two groups of slide bars are arranged in parallel on both sides of the transverse screw 13. The two ends of the slide bars are respectively fixedly connected to the two ends of the U-shaped frame 12. The transverse moving seat 14 is slidably sleeved on the slide bars, and the slide bars limit the horizontal movement of the transverse moving seat 14 along the transverse screw 13.
[0024] In order to ensure that the rotation angles of the first insert bar 7 and the second insert bar 10 can only be 90°, stop bars are horizontally installed above and below the disc 5. The upper stop bar is used to limit the first insert bar 7, and the lower stop bar is used to limit the second insert bar 10. In the initial state, the first insert bar 7 is in the horizontal position, and the arc-shaped clamping strips 8 at the ends of the two groups of first insert bars 7 are used to clamp and fix appropriate electrical instruments.
[0025] The second insert bar 10 is located below the disc 5 and is vertically arranged. At this time, the second insert bar 10 is limited and fixed by the stop bar below the disc 5. The first motor drives the rotating rod 4 and the disc 5 to rotate. The first insert bar 7 and the second insert bar 10 rotate with the disc 5. The second insert bar 10 rotates to the horizontal position, and the U-shaped clamping strips 11 at the ends of the two groups of second insert bars 10 are used to clamp and fix appropriate electrical instruments. At this time, the first insert bar 7 rotates to above the disc 5 and is vertically arranged, and the first insert bar 7 is limited and fixed by the stop bar above the disc 5.
[0026] When the size of the instrument to be repaired does not match the arc-shaped clamping strip 8 or the U-shaped clamping strip 11, in order to quickly replace the arc-shaped clamping strip 8 or the U-shaped clamping strip 11, positioning grooves 15 are opened on both the first insert bar 7 and the second insert bar 10. Through holes communicating with the first slot 6 and the second slot 9 are respectively opened on the end faces of the disc 5 on one side of the first slot 6 and the second slot 9. Connecting frames 16 are fixedly installed on the end faces of the disc 5 outside the through holes. Insert rods 17 are slidably installed on the connecting frames 16. The ends of the insert rods 17 extend into the corresponding positioning grooves 15 through the through holes. The insert rods 17 are used to limit and fix the first insert bar 7 and the second insert bar 10, and the insert rods 17 are slidably connected to the disc 5. Snap rings 18 are fixedly sleeved on the middle parts of the insert rods 17. Return springs 19 are sleeved on the insert rods 17. One end of the return spring 19 is fixedly connected to the snap ring 18, and the other end is fixedly connected to the inner wall of the connecting frame 16 far from the disc 5. By pulling the insert rod 17, the insert rod 17 can be pulled out of the positioning groove 15, and then the corresponding first insert bar 7 or the second insert bar 10 can be taken out for replacement. The operation is simple and fast.
[0027] The working principle of the metallurgical electrical instrument maintenance device of the present utility model is as follows:
[0028] In this device, multiple first inserting strips 7 fixed with arc-shaped clamping strips 8 and multiple second inserting strips 10 fixed with U-shaped clamping strips 11 can be prepared in advance, and each arc-shaped clamping strip 8 and U-shaped clamping strip 11 has a different diameter or different size.
[0029] When clamping and maintaining the instrument, first select whether to use the arc-shaped clamping strip 8 or the U-shaped clamping strip 11 according to the shape of the instrument. If using the arc-shaped clamping strip 8, the instrument to be maintained can be directly taken out, and then a part of its arc-shaped side is attached to the inner wall of the arc-shaped clamping strip 8 on the first concave seat 2. Subsequently, the second motor is started forward, and its output shaft drives the transverse screw rod 13 to rotate, so that the transverse moving seat 14 and the second concave seat 3 can be driven to move towards the direction of the first concave seat 2 until another arc-shaped clamping strip 8 also fits the arc-shaped side of the instrument to be maintained, and then the second motor is turned off. At this time, the clamping and fixing of the instrument is completed, and then it can be disassembled and maintained by using a disassembly tool.
[0030] If it is necessary to use the U-shaped clamping strip 11, the two first motors can be started first, so that the two rotating rods 4 rotate until the two first inserting strips 7 respectively contact the two upper retaining rods, and then the first motors are turned off. At this time, the U-shaped clamping strip 11 is in a horizontal state with the maintenance table 1. Then, one side of the rectangular instrument is clamped into the U-shaped clamping strip 11 on the first concave seat 2, and then the second motor is started forward, and the instrument can be clamped and fixed by using another U-shaped clamping strip 11. Subsequently, it is disassembled and maintained.
[0031] In subsequent use, if the outer diameter of the instrument to be maintained is large and does not match the arc-shaped clamping strip 8 or the U-shaped clamping strip 11, the corresponding inserting rod 17 can be pulled first to pull it out of the corresponding positioning groove 15. At this time, the reset spring 19 is in a compressed state under the pressure of the snap ring 18. Subsequently, the corresponding first inserting strip 7 or the second inserting strip 10 is pulled out, and then the first inserting strip 7 or the second inserting strip 10 that meets the requirements is inserted into the first slot 6 or the second slot 9. Then, the inserting rod 17 is released, and the reset spring 19 releases its elastic force to directly push the inserting rod 17 into the positioning groove 15, so as to complete the replacement of the arc-shaped clamping strip 8 or the U-shaped clamping strip 11, and then continue to be clamped and used.

Without departing from the design concept of the present utility model, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model.
