Description

Technical Field

[0001] The invention relates to the field of electrical instrument maintenance devices, and in particular to a metallurgical electrical instrument maintenance device and a use method thereof. Background Art

[0002] Electrical instruments generally refer to electrical measuring instruments, which mainly refer to meters and instruments used to measure, record and meter various electrical quantities. During the long-term use of electrical instruments, a certain degree of failure will occur. Therefore, maintenance equipment is needed to repair the electrical instruments.

[0003] Chinese patent CN218698606U discloses a metallurgical electrical instrument maintenance device, including a support base plate, the upper left part and the upper right part of the support base plate are fixedly connected with support columns, and the upper ends of the two support columns are interspersed with extension columns. The patent is provided with two clamping assemblies on the two clamping assemblies, which can clamp electrical instruments of different sizes to improve flexibility. However, on the one hand, when the metallurgical electrical instrument maintenance device of the above structure is in use, before the clamping frame clamps and fixes the electrical instrument, the staff needs to hold it with one hand until it is completely clamped, which makes the clamping of the electrical instrument not convenient enough. On the other hand, when the metallurgical electrical instrument maintenance device of the above structure is in use, when the electrical instrument is repaired, the maintenance box needs to be placed on the support plate, and the maintenance box has a certain volume, which will reduce the space available for maintenance by the maintenance personnel. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a metallurgical electrical instrument maintenance device and a use method thereof.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A metallurgical electrical instrument maintenance device comprises a base plate, a pair of support columns are symmetrically arranged on both sides of the top of the base plate, adjustment plates are inserted and connected in the two support columns, a maintenance platform is fixed on the top of the two adjustment plates, and vertical plates are symmetrically fixed on both sides of the top of the maintenance platform; through sliding holes are symmetrically opened above the two vertical plates, connecting rods are penetrated in the sliding holes, clamping frames are installed on the opposite ends of the two connecting rods, ear plates are symmetrically fixed on one side wall of the two clamping frames, and the two ear plates are threadedly connected by clamping screws.

[0007] Each of the adjustment plates is provided with adjustment holes at equal distances for adjusting the height; a horizontal plate is fixed between the two support columns, and slots are symmetrically provided at both ends of the horizontal plate, and plug plates are connected through the adjustment holes and the slots for fixing the adjustment plates.

[0008] Preferably, the aperture of the slot is consistent with the aperture of the adjustment hole.

[0009] A mounting hole is provided in the center of the horizontal plate, and a through hole is provided on the maintenance platform, and the mounting hole and the through hole are coaxially arranged; an electric telescopic rod is fixedly provided through the mounting hole, and a top plate is installed on the telescopic part of the electric telescopic rod, and the top plate is adapted to the size and shape of the through hole, so as to prevent parts and maintenance tools from falling through the gap when the top plate is embedded in the through hole.

[0010] Furthermore, the top ends of the two vertical plates are symmetrically provided with connecting holes in the middle, the connecting holes are perpendicular to and communicate with the central axis of the sliding hole, and a locking bolt is arranged in each of the connecting holes. The connecting rod drives the clamping frame to move and flip, and the sliding hole cooperates with the connecting rod to play a limiting role, so as to prevent the clamping frame from flipping when the clamping screw is screwed. The connecting hole facilitates the locking bolt to be screwed into the vertical plate, so that the locking bolt can tightly hold the connecting rod to prevent it from shaking.

[0011] Furthermore, the locking bolt is threadedly connected to the connecting hole, and the locking bolt is made of stainless steel. The locking bolt can better control the state of the connecting rod in the sliding hole, so that the connecting rod can move and rotate better in the sliding hole.

[0012] Furthermore, the connecting rod is bolted to the clamping frame, and the clamping frame is welded to the ear plate. The clamping frame is used to clamp and limit the electrical instrument to avoid shaking during maintenance of the electrical instrument to affect the maintenance worker's operation.

[0013] Furthermore, the clamping screw is a bidirectional screw. Rotating the clamping screw can make the two ear plates move relative to each other, and the movement of the ear plates can more easily drive the clamping frame to clamp or loosen the electrical instrument.

[0014] Furthermore, the support column is welded to the bottom plate, and bottom columns are fixed at the four corners of the bottom end of the bottom plate. By adopting the above technical solution, the bottom plate can better support the support column and the maintenance platform.

[0015] Furthermore, the bottom column is welded to the bottom plate, and the adjustment plate is bolted to the maintenance platform. By adopting the above technical solution, the bottom plate can fix the bottom column more stably.

[0016] Furthermore, the vertical plate is made of stainless steel.

[0017] A maintenance box is embedded in one side of the maintenance platform, and a box cover is arranged on the top of the maintenance box.

[0018] Furthermore, the box cover is in the same horizontal plane as the maintenance platform when in a closed state, so that the maintenance box is prevented from occupying space on the maintenance platform.

[0019] A stretching rod is installed in the center of the side wall of the horizontal plate, the telescopic part of the stretching rod is connected to a lifting rod, a seat plate is arranged at the top of the lifting rod, a moving seat is installed at the bottom of the lifting rod, and a sliding groove is opened on the bottom plate corresponding to the lifting rod.

[0020] The present invention also provides a method for using the metallurgical electrical instrument maintenance device. First, the electrical instrument to be repaired is taken out and placed on the top plate. The electric telescopic rod drives the top plate to rise to the two clamping frames; the locking bolt is adjusted so that the connecting rod slides in the sliding hole; the clamping screw is rotated to bring the two clamping frames closer to clamp the electrical instrument; after the clamping frames have finished clamping the electrical instrument, the locking bolt is tightened. Then the electric telescopic rod drives the top plate to be retracted into the through hole. When the maintenance angle of the electrical instrument needs to be adjusted, the locking bolt is adjusted so that the rotation of the connecting rod drives the rotation of the clamping frame. After it rotates to a suitable angle, the locking bolt is tightened to fix the connecting rod.

[0021] Preferably, the stretching rod pushes the lifting rod to make the movable seat slide out of the slide groove, and the height of the seat plate is adjusted according to the height of the maintenance personnel.

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention provides an electric telescopic rod and a top plate, so that the electrical instrument can be clamped without holding it, which is convenient and quick. In addition, after the electrical instrument is clamped, the top plate can be retracted and embedded in the maintenance table, which can avoid the top plate from occupying the adjustment space when the angle is turned over to adjust the larger electrical instrument during maintenance, and ensure the flatness of the maintenance table to avoid the loss of parts, maintenance tools, etc.

[0024] 2. The present invention provides a maintenance box on the maintenance table, and the box cover is at the same level as the maintenance table, so that the maintenance personnel can easily take the maintenance tools. On the one hand, it avoids occupying the space of the maintenance table, and on the other hand, it ensures that there are no additional protrusions on the surface of the maintenance table, so as to avoid hiding parts and maintenance tools in the dead corners of the maintenance table.

[0025] 3. In order to solve the problem that when the existing metallurgical electrical instrument maintenance device is in use, it takes a certain amount of time for maintenance personnel to repair the electrical instruments, and long-term standing maintenance will increase the fatigue of the maintenance personnel, thereby causing the electrical instrument maintenance device to be less convenient and comfortable when in use, the present invention arranges a stretching rod on one side wall of the transverse plate. When the maintenance personnel repair the electrical instruments, the stretching rod pushes the lifting rod to slide out of the slide groove through the moving seat. The lifting rod can adjust the height of the seat board according to the height of the maintenance personnel. The seat board allows the maintenance personnel to sit to repair the electrical instruments, avoiding standing maintenance that increases the fatigue of the maintenance personnel. The seat board and the electrical instrument maintenance device are designed as an integrated whole, which can improve the convenience and comfort when in use. BRIEF DESCRIPTION OF THE DRAWINGS

A plug-in plate 6 is connected through the adjustment holes 3 and the slots 5, and the plug-in plate 6 can make the adjustment plate 2 stably fixed in the support columns 1, so that the staff can adjust the height of the maintenance device. The parts of the two ends of the cross plate 4 without the slots 5 are welded to the support columns 1.

[0036] A maintenance platform 10 is fixed on the top of the two adjustment plates 2, and vertical plates 14 are symmetrically fixed on both sides of the top of the maintenance platform 10; through sliding holes 15 are symmetrically opened on the top of the two vertical plates 14, and connecting rods 16 are penetrated in the sliding holes 15. The maintenance platform 10 can fix the vertical plates 14 more stably, and the sliding holes 15 facilitate the connecting rods 16 to move and rotate on the vertical plates 14.

[0037] A clamping frame 17 is installed at the opposite end of the two connecting rods 16, and ear plates 18 are symmetrically fixed to one side wall of the two clamping frames 17. The two ear plates 18 are threadedly connected by a clamping screw 19. The sliding hole 15 cooperates with the connecting rod 16 to play a limiting role, so as to prevent the clamping frame 17 from turning over when the clamping screw 19 is screwed. The two ear plates 18 can be relatively moved by rotating the clamping screw 19, and the movement of the ear plates 18 can more easily drive the clamping frame 17 to loosen the clamping of the electrical instrument.

[0038] The horizontal plate 4 is provided with a mounting hole 7 in the center, and the maintenance platform 10 is provided with a through hole 11, and the mounting hole 7 is coaxially arranged with the through hole 11; an electric telescopic rod 8 is fixedly arranged through the mounting hole 7, and the mounting hole 7 can stably fix the electric telescopic rod 8 on the horizontal plate 4. The telescopic part of the electric telescopic rod 8 is provided with a top plate 9, and the electric telescopic rod 8 can more easily drive the top plate 9 to rise and fall, so that the staff can avoid holding it by hand when clamping and limiting the electrical instrument. The top plate 9 is adapted to the through hole 11 in size and shape, so that when the top plate 9 is embedded in the through hole 11, it can prevent parts and maintenance tools from falling through the gap.

[0039] A maintenance box 12 is embedded in one side of the maintenance platform 10. The maintenance box 12 can be more convenient for placing maintenance tools, so that maintenance personnel can use and replace maintenance tools more quickly when repairing electrical instruments. A box cover 13 is provided on the top of the maintenance box 12. The box cover 13 is hingedly connected to the maintenance box 12. When the box cover 13 is closed, it can be in the same horizontal state as the maintenance platform 10, so as to avoid the maintenance box 12 taking up space when not in use.

[0040] In this embodiment, the support column 1 is welded to the bottom plate 22 , and bottom columns 23 are fixed at the four corners of the bottom end of the bottom plate 22 . The bottom plate 22 can better support the support column 1 and the maintenance platform 10 .

[0041] In this embodiment, the base column 23 is welded to the base plate 22, and the adjustment plate 2 is bolted to the maintenance platform 10. The base plate 22 can fix the base column 23 more firmly, and the support column 1 cooperates with the adjustment plate 2 to better adjust the height of the maintenance platform 10.

[0042] The vertical plate 14 is made of stainless steel.

[0043] In this embodiment, the connecting rod 16 is bolted to the clamping frame 17, and the connecting rod 16 can more firmly fix the clamping frame 17, and the connecting rod 16 can better drive the clamping frame 17 to move and flip. The clamping frame 17 is welded to the ear plate 18, and the clamping frame 17 clamps and limits the electrical instrument to prevent shaking during maintenance of the electrical instrument and affect the maintenance worker's operation; by welding the clamping frame 17 to the ear plate 18, the clamping frame 17 can more firmly fix the ear plate 18.

[0044] In this embodiment, the top ends of the two vertical plates 14 are symmetrically provided with connection holes 20, which are perpendicular to and communicate with the central axis of the sliding hole 15. A locking bolt 21 is provided in each of the connection holes 20, and the connection holes 20 can make it easier for the locking bolt 21 to be screwed into the vertical plate 14, so that the locking bolt 21 can tightly hold the connecting rod 16 to prevent it from shaking.

[0045] In this embodiment, the locking bolt 21 is threadedly connected to the connecting hole 20. The locking bolt 21 is made of stainless steel. The locking bolt 21 can better control the state of the connecting rod 16 in the sliding hole 15, so that the connecting rod 16 can better move and rotate in the sliding hole 15.

[0046] The method of using the metallurgical electrical instrument maintenance device is as follows: when using, first take out the electrical instrument to be repaired and place it on the top plate 9, and the electric telescopic rod 8 drives the top plate 9 to rise to the two clamping frames 17; adjust the locking bolt 21 so that the connecting rod 16 slides in the sliding hole 15; turn the clamping screw 19 to bring the two clamping frames 17 close to clamp the electrical instrument, and the electrical instrument can be quickly clamped without the staff's hand support; after the clamping frame 17 has clamped the electrical instrument, tighten the locking bolt 21. Then the electric telescopic rod 8 drives the top plate 9 to be retracted into the through hole 11, so that when adjusting the maintenance angle of the electrical instrument, the top plate 9 can be prevented from occupying the space below and affecting the adjustment of the angle. When the maintenance angle of the electrical instrument needs to be adjusted, adjust the locking bolt 21 so that the rotation of the connecting rod 16 drives the rotation of the clamping frame 17, and when it rotates to the appropriate angle, tighten the locking bolt 21 to fix the connecting rod 16.
