Description

Technical Field

[0001] The invention relates to the technical field of power equipment installation, and in particular to an intelligent-based insulator replacement auxiliary device. Background Art

[0002] Insulators (post insulators) installed on the cross frame of the pole play the role of isolating live bodies and can bear the gravity of the conductor itself. They are widely used in power transmission lines. After a period of use, some insulators are damaged and need to be replaced.

[0003] The insulator supports the conductor. When replacing the insulator, the conductor needs to be temporarily supported first, that is, the conductor is erected using an insulator replacement auxiliary device. The existing insulator replacement auxiliary device generally requires two people to operate when in use, that is, one person is used to operate and stabilize the insulator auxiliary device, and the other person replaces the new insulator. During this process, the two people are climbing at high altitudes or are in close positions, which poses a great safety hazard. In particular, when replacing an insulator on a single cement pole, climbing at a different position will pose a greater safety hazard. For this reason, the present invention provides an insulator replacement auxiliary device based on intelligence. Summary of the invention

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1:

[0049] like Figure 1-Figure 12 As shown, an embodiment of the present invention provides an intelligent insulator replacement auxiliary device, including: a threaded sleeve 1, a bottom cylinder 3, a top cylinder 4, a limit ring 17, an insulating telescopic member 7, a square rod 8, a lifting platform 20, a threaded rod 11 and a lower wire head structure 23.

[0050] The threaded sleeve 1, the bottom cylinder 3, and the top cylinder 4 constitute an outer shell structure, and a limiting ring 17 is arranged inside the threaded sleeve 1 and between the bottom cylinder 3 and the top cylinder 4. When in use, the user rotates the top cylinder 4 so that the bottom cylinder 3 and the top cylinder 4 can clamp the limiting ring 17 or allow the limiting ring 17 to rotate freely, thereby forming a freely operable outer shell limiting structure.

[0051] Specifically, the side of the threaded sleeve 1 is fixedly connected with a cross clamp assembly 2. Before using the device, the threaded sleeve 1 needs to be fixed by using the cross clamp assembly 2; for example, the cross clamp assembly 2 is fixedly clamped on the angle steel cross frame fixed on the cement pole.

[0052] The top end of the bottom cylinder 3 is stuck in the inner side of the threaded sleeve 1, the top cylinder 4 is coaxially arranged with the bottom cylinder 3, and the inner hole of the top cylinder 4 is connected with the inner hole of the bottom cylinder 3, the outer side of the top cylinder 4 is threadedly connected with the threaded sleeve 1, and the outer side of the top end of the top cylinder 4 is fixedly connected with an annular wheel 5, and the top cylinder 4 is driven to rotate by operating the annular wheel 5. The top cylinder 4 is threadedly connected with the threaded sleeve 1, so that the top cylinder 4 and the threaded sleeve 1 can move relative to each other in the vertical direction, and the top end of the bottom cylinder 3 is stuck in the inner side of the threaded sleeve 1, so that the distance between the bottom cylinder 3 and the top cylinder 4 is increased / decreased.

[0053] The limiting ring 17 is located on the inner side of the threaded sleeve 1, and the limiting ring 17 is located between the top end of the bottom cylinder 3 and the bottom end of the top cylinder 4. The purpose of the limiting ring 17 is to limit the rotation of the square rod 8. When the user adjusts the bottom cylinder 3 and the top cylinder 4 to a state where the limiting ring 17 is clamped and fixed, the square rod 8 cannot rotate. Conversely, when the limiting ring 17 is adjusted to be rotatable, the square rod 8 can also be manipulated to rotate.

[0054] The lower half of the insulating telescopic part 7 is located on the inner side of the top cylinder 4, and the insulating telescopic part 7 and the inner side of the top cylinder 4 can be connected by sliding up and down. The top cylinder 4 can further stabilize the insulating telescopic part 7. The bottom end of the insulating telescopic part 7 is fixedly connected with a square rod 8, and a center hole 10 is opened at the bottom end of the square rod 8. A lifting platform 20 is fixedly installed on the top of the insulating telescopic part 7. The threaded rod 11 is rotatably connected to the bottom cylinder 3, and the threaded rod 11 and the bottom cylinder 3 are restricted in axial movement along the bottom cylinder 3. The bottom end of the threaded rod 11 extends out of the bottom cylinder 3, and a hand crank 13 is fixedly installed at the bottom end of the threaded rod 11. The outer side of the threaded rod 11 is threadedly installed with a threaded fitting kit 12, and the threaded fitting kit 12 is fixedly installed on the inner side of the center hole 10. For example, the threaded fitting kit 12 is inserted into the center hole 10 of the square rod 8, and then the screw is fixedly installed on the side of the square rod 8 laterally. The end of the screw is squeezed on the outer side of the threaded fitting kit 12 to achieve the fixation of the threaded fitting kit 12 and the square rod 8.

[0055] A down-line head structure 23 and a camera mounting frame 21 are fixedly installed on the top of the lifting platform 20, and a camera assembly 22 is fixedly installed on the side of the camera mounting frame 21. The camera assembly 22 faces the position where the down-line head structure 23 is located, so that the camera assembly 22 can obtain images around the position where the down-line head structure 23 is located. A display instrument 6 is fixedly connected to the side of the bottom cylinder 3, and the display instrument 6 is communicatively connected with the camera assembly 22. The camera assembly 22 transmits the acquired image to the display instrument 6 and displays the relevant image on the display instrument 6 to facilitate the ground operator to observe the specific situation.

[0056] A sliding groove 9 is provided on the side of the square rod 8, and a side through hole 17a is provided on the side of the limit ring 17. A mating key block 18 is fixedly installed inside the side through hole 17a. One end of the mating key block 18 is located inside the sliding groove 9, so that the square rod 8 and the limit ring 17 can only slide in the up and down directions and cannot rotate relative to each other.

[0057] After the cross clamp assembly 2 is fixedly installed, the threaded sleeve 1 is in a fixed state, and the operator on the pole manipulates the annular wheel 5 to rotate the top cylinder 4 relative to the threaded sleeve 1. At this time, the top cylinder 4 moves slightly upward, so that the limit ring 17 between the bottom cylinder 3 and the top cylinder 4 is loosened, and the operator on the pole can operate the insulating telescopic part 7, the lifting platform 20 and the lower wire head structure 23 to rotate (the insulating telescopic part 7, the lifting platform 20 and the lower wire head structure 23 all rotate around the axis of the insulating telescopic part 7) to adjust the lower wire head structure 23 to a suitable position. Generally, the lower wire head structure 23 is adjusted to a position where it can clamp or pull the wire, and then the top cylinder 4 is tightened. The operator on the pole removes the wire crimping frame on the top of the original insulator, and the lower wire head structure 23 is removed. The operator on the surface can operate the hand crank 13 to drive the threaded rod 11 to rotate. Since the threaded fitting kit 12 is restricted by the square rod 8 and cannot rotate, the threaded fitting kit 12 and the threaded rod 11 undergo relative threaded rotation, driving the threaded fitting kit 12 to move upward, thereby moving the square rod 8, the insulating telescopic member 7, the lifting platform 20 and the lower wire head structure 23 upward. The lower wire head structure 23 lifts the wire upward by about 40CM. The operator on the pole replaces the new insulator. Then the operator on the ground reverses the hand crank 13 to make the square rod 8, the insulating telescopic member 7, the lifting platform 20 and the lower wire head structure 23 fall downward, and the wire falls on the newly installed insulator. After the wire crimping frame is installed on the new insulator, the cross clamp assembly 2 is removed and the auxiliary device is removed.

[0058] In one embodiment, the cross clamp assembly 2 includes: a cross frame 201 , an extrusion plate 205 and a threaded fastening rod 204 .

[0059] The back side of the transverse frame 201 is fixedly connected to the outer side surface of the threaded sleeve 1, and the transverse frame 201 has a top plate 201a and a bottom plate 201b which are distributed in parallel up and down. The area between the top plate 201a and the bottom plate 201b is the clamping area, and the extrusion plate 205 is arranged between the top plate 201a and the bottom plate 201b. The bottom of the top plate 201a is fixedly connected with an anti-skid ridge 202, and the anti-skid ridge 202 plays an anti-skid role. The bottom of the bottom plate 201b is fixedly connected with a thickened portion 203, and a vertically penetrating threaded hole is provided at the bottom of the thickened portion 203. A threaded fastening rod 204 is installed on the internal thread of the threaded hole, and the top end of the threaded fastening rod 204 is rotatably connected to the bottom surface of the extrusion plate 205.

[0060] When using the cross clamp assembly 2 for fixing, insert the cross section of the angle steel on the concrete pole between the top plate 201a and the extrusion plate 205, then rotate the threaded fastening rod 204, and the top end of the threaded fastening rod 204 pushes the extrusion plate 205 upward, so that the top plate 201a and the extrusion plate 205 are clamped and fixed on the angle steel on the concrete pole; when disassembling, just reverse the threaded fastening rod 204.

[0061] like Figure 7 As shown, in one embodiment, the lower thread head structure 23 includes: a U-shaped frame 2301 , a horizontal axis 2304 , a first spring 2305 , an L-shaped plate 23011 , a guide column 2308 , and a second spring 2309 .

[0062] The bottom of the U-shaped frame 2301 is fixedly connected to the top of the lifting platform 20, the top of the U-shaped frame 2301 faces upward, and a guide bevel 2302 is arranged on the inner side of the U-shaped frame 2301, and the guide bevel 2302 is used to guide the wire to slide. A small U-shaped part 2303 is fixedly connected to the top of one side of the U-shaped frame 2301, and a transverse through hole is opened on the side of the small U-shaped part 2303. The transverse axis 2304 is located in the transverse through hole and slides. The transverse axis 2304 can slide horizontally relative to the transverse through hole. One end of the transverse axis 2304 is located on the inner side of the U-shaped frame 2301, and the transverse axis 2304 located on the inner side of the U-shaped frame 2301 is set as a conical part. A first spring 2305 is sleeved on the transverse axis 2304 located on the inner side of the small U-shaped part 2303, and a pin 2305 is fixedly installed on the side of the transverse axis 2304 located on the inner side of the small U-shaped part 2303 06, the pin 2306 is against one end of the first spring 2305, and the other end of the first spring 2305 is against the inner side of the small U-shaped part 2303, and the elastic force of the first spring 2305 drives the horizontal axis 2304 to slide toward the inner side of the U-shaped frame 2301, and an inverted notch 2307 is provided on the outer side of the U-shaped frame 2301, and a vertically arranged guide column 2308 is fixedly installed on the inner side of the inverted notch 2307, and a second spring 2309 is sleeved on the guide column 2308, and an L-shaped plate 23011 is slidably installed on the guide column 2308 and above the second spring 2309, and the second spring 2309 drives the L-shaped plate 23011 to move upward to the uppermost position, and the vertical part of the L-shaped plate 23011 blocks one end of the horizontal axis 2304, and a pull ring 23010 is fixedly installed on the side of the L-shaped plate 23011.

[0063] When going online (inserting the wire into the U-shaped frame 2301), the lifting platform 20 is used to drive the lower wire head structure 23 to move upward as a whole. The personnel on the ground can slide the L-shaped plate 23011 downward through the pull rope connected to the pull ring 23010 (the drawing is not drawn, and the pull rope needs to be made of insulating material). The L-shaped plate 23011 presses the second spring 2309 downward to compress the second spring 2309. At this time, as the lower wire head structure 23 moves upward as a whole, the wire is squeezed on the conical part of the horizontal axis 2304, causing the horizontal axis 2304 to move horizontally, and the wire enters the inner side of the U-shaped frame 2301. Then the pull rope on the pull ring 23010 is released, and the L-shaped plate 23011 slides upward under the action of the second spring 2309, blocking the horizontal sliding of the horizontal axis 2304, thereby preventing the wire from detaching from the lower wire head structure.

[0064] When lowering the line (making the conductor leave the inside of the U-shaped frame 2301), after the conductor has been supported on the newly replaced insulator, the lifting platform 20 drives the lower line head structure 23 to move downward as a whole, and the conductor is guided by the inclined guide portion 2302 to relatively upwardly squeeze the tapered portion of the horizontal axis 2304. The user slides the L-shaped plate 23011 downward, and the conductor is squeezed to cause the horizontal axis 2304 to move laterally, so that the conductor leaves the inside of the U-shaped frame 2301. This process is easy to use and can be completed by ground operators in conjunction with the image information displayed on the display instrument, thereby reducing the difficulty of the operation for operators on the poles.

[0065] like Fig.12 As shown, in another embodiment, the lower thread head structure 23 includes: a suspension 23a and a hook 23b.

[0066] The bottom end of the suspension 23a is fixedly connected to the top of the lifting platform 20, and a hook 23b is fixedly installed on the suspension 23a. The hook 23b can be hung on the wire, and when the lifting platform 20 drives the lower wire head structure 23 to move up and down, the wire is driven to move up and down.

[0067] In one embodiment, a step portion 1a is provided on the inner side of the bottom end of the threaded sleeve 1, an outer ring 3c is fixedly connected to the outer side of the top end of the bottom cylinder 3, and a threaded portion 4a is provided on the outer side of the bottom end of the top cylinder 4.

[0068] The step portion 1 a is located below the outer ring member 3 c , thereby ensuring that the threaded sleeve 1 lifts the bottom cylinder 3 , and the threaded portion 4 a is threadedly connected with the inner side of the threaded sleeve 1 .

[0069] like Figure 5As shown, in one embodiment, an inner ring member 3a is fixedly connected to the inner side of the bottom cylinder 3 and near the bottom end, a limiting ring 14 is fixedly connected to the outer side of the threaded rod 11 and near the bottom end, the limiting ring 14 is located on the inner side of the bottom cylinder 3, and the limiting ring 14 is located below the inner ring member 3a, a wear-resistant ring 15 is provided on the inner side of the bottom cylinder 3 and below the limiting ring 14, and a bottom support sleeve 16 is threadedly fixedly installed on the bottom end of the bottom cylinder 3.

[0070] After the bottom support sleeve 16 is installed, the inner ring 3a and the wear-resistant ring 15 restrict the upward and downward sliding of the limiting ring 14 of the threaded rod 11, so that the threaded rod 11 can only rotate. The designed wear-resistant ring 15 is used to bear the downward extrusion force of the limiting ring 14 and the friction between the relative rotation. The wear-resistant ring 15 is made of high-hardness, wear-resistant material, and needs to be replaced regularly.

[0071] In one embodiment, the side of the bottom cylinder 3 is fixedly connected with a welding fastener 3b. After the threaded sleeve 1 and the bottom cylinder 3 are installed, the welding fastener 3b is fixedly connected to the side of the bottom cylinder 3 by a welding process. The display instrument 6 and the welding fastener 3b are fixedly installed by screws. The function of the welding fastener 3b is to facilitate the installation of the display instrument 6.

[0072] In one embodiment, an auxiliary support frame 19 is fixedly installed between the bottom of the lifting platform 20 and the side of the insulating telescopic member 7. The auxiliary support frame 19 and the insulating telescopic member 7 are both made of insulating materials. The auxiliary support frame 19 is used to auxiliary support the lifting platform 20 so that the lifting platform 20 has a more stable structural characteristic.

[0073] In one embodiment, two sliding grooves 9 are provided, and the two sliding grooves 9 are respectively located on a symmetrical side of the square rod 8 , and two matching key blocks 18 are provided, and the two matching key blocks 18 correspond to the two sliding grooves 9 .

[0074] The two mating key blocks 18 can position the square rod 8 at the center of the bottom cylinder 3 , and the two mating key blocks 18 can stably keep the square rod 8 and the limiting ring 17 from rotating relative to each other.
