Description

Technical Field

[0001] The present invention relates to the technical field of substation recovery equipment, and in particular to an intelligent lifting device for a grounding wire. Background Art

[0002] Grounding wires are widely used in power systems. They are a safety device used to temporarily short-circuit and ground power-off equipment. The grounding wire connects the zero potential of the earth to the electrical equipment, so that the connected electrical equipment is at the same potential. Installing short-circuit grounding wires on the equipment and lines under maintenance is one of the effective measures to ensure the safety of power production personnel. It can discharge the residual charge on the maintenance equipment to the earth; discharge the induced charge generated by the maintenance equipment due to the proximity of the charged body to the earth; and when a sudden power supply occurs, the power supply current can be short-circuited to the ground to limit the increase in the voltage of the maintenance equipment to the ground. The grounding wire is a safety barrier to protect maintenance personnel and is the lifeline of power employees.

[0003] At present, there are many problems and potential risks in the connection of grounding wires that need to be solved urgently. The height of the grounding point on the 110 kV side of the main transformer is about 5m, and a series of equipment such as casing porcelain bottles, double-layer oil pipes, cable frames, etc. are distributed below it. The space layout of these equipment is tight, and there is seriously insufficient space for operators to hang the grounding wires. The narrowest part is less than 0.6m. The operators holding the grounding wires even find it difficult to turn around, which is very unfavorable for the installation and removal of the grounding wires. The existing devices cannot effectively deal with the above problems. For example, the operating rods often used by staff are long and heavy. When lifted high, they are very easy to swing, causing accidental damage to the porcelain bottles.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Embodiment 1

[0033] Reference Figure 1-3, an intelligent lifting device for grounding wire, comprising a base 1, a lifting assembly is arranged on the base 1, the lifting assembly comprises a multi-section electric telescopic rod 2 vertically fixed on the base 1, the multi-section electric telescopic rod 2 is arranged vertically, and a wire clamp mounting frame 3 is installed on the top of the multi-section electric telescopic rod 2. The base 1 and the multi-section electric telescopic rod 2 constitute an electric lifting structure as a whole, with a small storage area and a high extension height, and the base 1 and the bottom of the multi-section electric telescopic rod 2 are fixed by brackets and expansion screws. A laser radar ranging module can be installed at the bottom of the multi-section electric telescopic rod 2, and a reflection point is installed at the top to achieve the measurement of the extension height. The wire clamp mounting frame 3 at the top includes a crossbar track, and a plurality of electric control clamps can be installed on the crossbar track, that is, the base of the electric control clamp is provided with an interface connected to the crossbar track, can be moved on the crossbar track, and can be locked by bolts, the electric control clamp is connected to the base by a universal ball bearing, its direction and angle are adjustable, and can be locked by bolts, and the clamp contains bolt holes, which can be connected to the grounding wire conductor. A driving mechanism matching the multi-section electric telescopic rod 2 is provided on the base 1 .

[0034] The driving mechanism includes a first motor 4 provided inside the base 1, the first motor 4 is coaxially fixed with a driving gear 5 and a first pulley 6, a driven gear 7 for driving the lifting is provided at the bottom of the multi-section electric telescopic rod 2, the driving gear 5 is meshed with the driven gear 7, and a second pulley 8 is also rotatably provided inside the base 1, the first pulley 6 is connected to the second pulley 8 by a belt transmission, and the rotating shaft of the second pulley 8 is coaxially provided with a first jack 9, and the first jack 9 can be plugged and matched with a first crank. The main purpose is to convert the rotary motion of the first motor 4 into linear motion, and realize the synchronous lifting and lowering of the multi-section electric telescopic rod 2 through a precise mechanical structure. Specifically, this lifting rod usually adopts a three-section push rod design. When each section is raised to the highest point, it will drive the next section to enter the threaded area on the screw, and at the same time, the nut of this section will be separated from the screw, and so on, until the last section is raised to the highest point. This design ensures that the lifting rod has a long stroke, and at the same time ensures the accuracy and stability of the lifting. The core principle is that only one nut moves on the screw at the same time, and the lifting section does not rotate, thereby realizing the synchronous lifting and lowering of the multi-section lifting rod. In the case that the first motor 4 fails to start, the first socket 9 can be plugged into the first crank handle, and the multi-section electric telescopic rod 2 can be raised and lowered by manual rotation.

[0035] A control console 10 is matched on the side of the base 1, and the control console 10 is used to control the above-mentioned related electrical equipment.

[0036] Working principle:

[0037] The device is set below the grounding point of the main transformer, and the device occupies a small area. After that, the grounding wire can be automatically carried to the hanging point, and the grounding wire can be automatically hung. The height can be flexibly adjusted according to the position of the grounding point. The first motor 4 can be used as the power for lifting. At the same time, when the first motor 4 fails and cannot be started, the first socket 9 can be plugged into the first crank handle, and the lifting and lowering of the multi-section electric telescopic rod 2 can be realized by manual rotation. The multi-section electric telescopic rod 2 has a set lifting strength and has the function of locking the height. When the grounding wire clamp is connected to the grounding point, it can avoid the device being hung on the grounding point due to power failure or control circuit failure, causing the grounding point to be overstressed and affecting the safety of the equipment.

That is, the two docking blocks 13 are provided with a socket matching the pin, and the two docking blocks 13 will not be rotated by inserting the pin, and the torsion spring makes the two docking blocks 13 maintain the vertical alignment, and only when an appropriate force is used, one of the docking blocks 13 will be rotated. The connecting rod 12 is hollow, and the connecting rod 12 can be made of aluminum alloy or carbon fiber to ensure a lighter weight. Both ends of the connecting rod 12 are surrounded by notches, and the number of notches is four. Both docking blocks 13 are provided with a clamping mechanism that can be matched with the notch.

The first spring 16 makes the two U-shaped blocks 14 keep moving away from each other, so that the two ends of the two U-shaped blocks 14 remain inserted into the slots. When the push rod 15 is pressed, the first spring 16 contracts, and the U-shaped block 14 corresponding to the push rod 15 disengages from the two slots, while driving the round rod 17 to push the two bending rods 18 to rotate. The raised ends of the two bending rods 18 push the corresponding U-shaped block 14 to move, so that the U-shaped block 14 disengages from the corresponding two slots, thereby achieving the effect of unlocking and disengaging the docking block 13 and the connecting rod 12.

[0043] The power mechanism includes a first gear 19 rotatably arranged on both sides of the column 11, racks 23 are arranged on both sides of the connecting rod 12, the column 11 is provided with a first notch matching the first gear 19, the two first gears 19 are respectively meshed and matched with the two racks 23, the two first gears 19 are coaxially fixed with a second gear 20, the two second gears 20 are meshed and matched, a second motor 21 for controlling the rotation of a second gear 20 is fixed on the side of the column 11, and a second socket 22 is coaxially provided on the rotating shaft of the other second gear 20, and the second socket 22 can be plugged and matched with a second crank handle. When the connecting rod 12 is set inside the column 11, the racks 23 on both sides of the connecting rod 12 can be meshed and set on the two first gears 19, and then the second motor 21 is started, and the second motor 21 drives the corresponding second gear 20 to rotate, and the two second gears 20 mesh and rotate, and respectively drive the corresponding first gears 19 to rotate. At this time, the rotation direction of the two first gears 19 cooperates with the two racks 23, which can drive the connecting rod 12 to rise and move. At the same time, after moving to the set height, another connecting rod 12 can be installed inside the column 11, that is, two connecting rods 12 are installed through the connecting mechanism, and then the lifting operation can be performed again. This method can flexibly adjust the height according to the position of the grounding point, that is, set the required number of connecting rods 12 and docking mechanisms, and the connecting rod 12 at the top fixes the wire clamp mounting frame 3. At the same time, the setting of several connecting rods 12 is convenient for subpackaging and transportation, and can be easily replaced after damage, effectively improving the service life of the device. At the same time, the rotating shafts of the two docking blocks 13 of the docking mechanism are installed with torsion springs. When the rotation adjustment setting is required, the pins on the corresponding rotating shafts of the two docking blocks 13 can be taken out. At this time, a rope is tied to the connecting rod 12 located above. After rising to the set height, the connecting rod 12 can be bent and changed in direction by pulling the rope. At this time, subsequent turning operations can be realized, obstacles can be effectively avoided, and flexible lifting settings can be achieved.

[0044] The limiting mechanism includes a third gear 24 rotatably arranged on both sides of the column 11. The column 11 is provided with a second notch matching the third gear 24.

[0045] The positioning mechanism includes two push frames 26 symmetrically arranged on the side of the column 11. The two push frames 26 are horizontally slidably connected to the column 11. Two fixed seats are arranged on the side of the column 11. The fixed seats are threaded with threaded rods 27, and the threaded rods 27 have a locking function.

The tops of the two push frames 26 are slidably penetrated with sliding rods. The two sliding rods are fixed with pawl blocks 28 at the opposite ends. The two pawl blocks 28 are respectively meshed and matched with two ratchet gears 25. The opposite ends of the two pawl blocks 28 are fixed with second springs 29. The two second springs 29 are horizontally fixedly connected to the column 11. The arrangement of the ratchet gear 25 and the pawl block 28 prevents the connecting rod 12 from sliding down after rising, and has the function of locking the height. And by rotating the two threaded rods 27, the corresponding two pawl blocks 28 can be driven to disengage from the ratchet gear 25, and the connecting rod 12 can be lowered without hindrance after disengagement.

[0047] The working principle of this embodiment: After the device is set up, when performing the lifting operation, a connecting rod 12 is set inside the column 11, so that the racks 23 on both sides of the connecting rod 12 are correspondingly meshed and set on the two first gears 19, and then the second motor 21 is started, and the second motor 21 drives the corresponding second gear 20 to rotate, and the two second gears 20 mesh and rotate, and respectively drive the corresponding first gears 19 to rotate. At this time, the rotation direction of the two first gears 19 cooperates with the two racks 23, which can drive the connecting rod 12 to rise and move. At the same time, after moving to the set height, a connecting rod 12 can be installed again inside the column 11, and the two connecting rods 12 are connected by a connecting mechanism, and then the lifting operation can be performed again. This method can flexibly adjust the height according to the position of the grounding point, that is, set the required number of connecting rods 12 and docking mechanisms to meet the flexible height setting, and the connecting rod 12 at the top fixes the wire clamp mounting frame 3.

[0048] At the same time, the arrangement of several connecting rods 12 is convenient for subpackaging and transportation, which can disperse the weight and facilitate transportation operations. And several connecting rods 12 can be easily replaced after one is damaged, effectively improving the service life of the overall device. At the same time, the rotating shafts of the two docking blocks 13 of the docking mechanism are installed with torsion springs, which can be rotated and adjusted when necessary, that is, the pins on the corresponding rotating shafts of the two docking blocks 13 are taken out, and at this time, a rope can be tied to the upper connecting rod 12. After rising to the set height, the connecting rod 12 can be bent and changed in direction by pulling the rope, and the subsequent turning operation can be realized at this time, effectively avoiding obstacles, realizing flexible elevation settings, and realizing use in complex situations.
