Description

Technical Field

[0001] This invention relates to the field of porcelain insulator installation technology, and more particularly to a porcelain insulator installation device for outdoor high and low voltage transformers. Background Technology

[0002] Porcelain insulators are porcelain-based electrical insulating materials used for external insulation protection of electrical appliances. Outdoor high and low voltage transformers are installed at relatively high locations. When installing porcelain insulators, it is inconvenient to carry them directly to high places due to their weight, which also increases the load on the installers. If the porcelain insulators are not carried properly, they may fall accidentally, posing a significant risk.

[0003] Therefore, in order to address the above problems, an outdoor high and low voltage transformer porcelain insulator installation device is being developed that can automatically lift and transport the porcelain insulators while providing anti-fall protection. Summary of the Invention

[0004] To overcome the drawbacks of existing devices, such as the inconvenience of carrying them to high places and the potential for accidental falls of porcelain insulators, this invention provides an outdoor high and low voltage transformer porcelain insulator installation device that automatically lifts and transports the insulators while providing fall protection.

[0005] The technical implementation of the present invention is as follows: an installation device for porcelain insulators of outdoor high and low voltage transformers, comprising a base, an installation rod, a first fixing block, a lifting mechanism and a protective mechanism. The installation rod is connected to the top of the base, and the first fixing block is connected to the upper and lower parts of the installation rod. The base is provided with a lifting mechanism for automatically lifting the porcelain insulator, and the lifting mechanism is provided with a protective mechanism for preventing the porcelain insulator from falling.

[0006] Optionally, the lifting mechanism includes a servo motor, a lead screw, and a lifting frame. The servo motor is bolted to the upper left side of the base. The lead screw is connected to the output shaft of the servo motor. The lead screw rotates between the first fixed blocks. The lifting frame is threadedly connected to the lead screw. The lifting frame is slidably connected to the mounting rod.

[0007] Optionally, the protective mechanism includes a fixed plate, a protective plate, a sliding plate, and a first spring. Two fixed plates are connected to the upper right side of the lifting frame. Protective plates are slidably connected between the front and rear sides of the fixed plates. Sliding plates are slidably connected between the sides of the fixed plates that are close to each other. A first spring is connected between the sliding plates and the lifting frame.

[0008] Optionally, it also includes a stabilizing mechanism, which includes a first fixing seat, a clip, and a stabilizing plate. The first fixing seat is connected to the front side of the first fixing block, the clip is rotatably connected to the first fixing seat, and the stabilizing plate is slidably connected to the base.

[0009] Optionally, it also includes a lifting mechanism, which includes a second fixed seat, a lifting frame, a sliding handle, and a torsion spring. The second fixed seat is bolted to the right side of the lifting frame, and the lifting frame is rotatably connected to the second fixed seat. Two torsion springs are connected between the lifting frame and the second fixed seat, and a sliding handle is slidably connected to the right side of the lifting frame.

[0010] Optionally, it also includes a fixing mechanism, which includes a fixed half-ring, a rotating half-ring, and a locking element. Two fixed half-rings are connected to the rear side of the mounting rod, and a rotating half-ring is rotatably connected to each fixed half-ring. A locking element is connected to the left side of each fixed half-ring.

[0011] Optionally, it also includes a locking mechanism, which includes a sliding block, a second fixed block, and a second spring. The right side of the right fixed plate is connected to the second fixed block, and the sliding block is slidably connected to the second fixed block. Two second springs are connected between the sliding block and the second fixed block.

[0012] Optionally, the protective panels are equipped with handles, making it easy for workers to push the sliding panels directly.

[0013] The advantages of this invention are: 1. This invention drives the lead screw to rotate through the output shaft of the servo motor, thereby causing the lifting frame to automatically lift and transport the porcelain insulator to a high place, solving the difficulty of carrying porcelain insulators to high places and making it easier for workers to quickly install porcelain insulators.

[0014] 2. This invention forms a frame-shaped protective space through the cooperation between the protective plate and the fixing plate, which prevents the porcelain insulator from falling during transportation and improves the protection effect of the porcelain insulator.

[0015] 3. By pulling the stabilizing plate forward, the present invention increases the contact area between the base and the ground, thereby making the base more stable and lowering the center of gravity of the mounting rod, thus improving the stability of the mounting rod.

[0016] 4. This invention changes the lever arm by pulling out the sliding handle, which reduces the force required for the worker to press the sliding handle. Then, the lifting frame pushes the sliding plate upward, making it easier for the worker to remove the porcelain insulator. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0026] An installation device for porcelain insulators of outdoor high and low voltage transformers, such as Figure 1 As shown, it includes a base 1, a mounting rod 2, a first fixing block 3, a lifting mechanism 4, and a protective mechanism 5. The mounting rod 2 is connected to the top of the base 1, and the first fixing block 3 is connected to the upper and lower parts of the mounting rod 2. The lifting mechanism 4 is provided on the base 1 for automatically lifting the porcelain insulator. The protective mechanism 5 is provided on the lifting mechanism 4 for preventing the porcelain insulator from falling.

[0027] When installing porcelain insulators on high and low voltage transformers outdoors, the transformers are located at a high altitude, and the porcelain insulators themselves are heavy, making it difficult to carry them manually. This device can be used to assist in the transportation of porcelain insulators, thus facilitating installation by workers at height. First, place the base 1 next to the utility pole where the porcelain insulator needs to be installed. Then, open the protective mechanism 5, place the porcelain insulator inside the protective mechanism 5, close the protective mechanism 5, and then start the lifting mechanism 4, which will automatically lift the porcelain insulator, making it easier for workers to quickly install it at height.

[0028] like Figure 1 and Figure 2 As shown, the lifting mechanism 4 includes a servo motor 41, a lead screw 42, and a lifting frame 43. The servo motor 41 is bolted to the upper left side of the base 1. The lead screw 42 is connected to the output shaft of the servo motor 41. The lead screw 42 rotates between the first fixed blocks 3. The lifting frame 43 is threadedly connected to the lead screw 42. The lifting frame 43 is slidably connected to the mounting rod 2. The lifting frame 43 is used to place the porcelain insulator. When the servo motor 41 is started, the output shaft of the servo motor 41 drives the lead screw 42 to rotate, thereby causing the lifting frame 43 to start moving and lifting.

[0029] When porcelain insulators need to be transported to a high place, they are first placed on the lifting frame 43. Then, the servo motor 41 is started directly. The output shaft of the servo motor 41 drives the lead screw 42 to rotate. The rotation of the lead screw 42 causes the lifting frame 43 to move upward. During the upward movement, the lifting frame 43 is steadily raised due to the guidance of the mounting rod 2, thus transporting the porcelain insulator to a high place for workers to directly pick up and install. After installation, the output shaft of the servo motor 41 is controlled to rotate in the opposite direction, so that the lifting frame 43 begins to move downward and reset. In summary, by driving the lead screw 42 to rotate through the output shaft of the servo motor 41, the lifting frame 43 begins to automatically rise, thereby transporting the porcelain insulator to a high place. This solves the difficulty of carrying porcelain insulators to high places and makes it easier for workers to quickly install the porcelain insulators.

[0030] like Figure 1 and Figure 3As shown, the protective mechanism 5 includes a fixed plate 51, a protective plate 52, a sliding plate 53, and a first spring 54. Two fixed plates 51 are connected to the upper right side of the lifting frame 43. The fixed plates 51 are symmetrically distributed on the left and right. The protective plates 52 are slidably connected between the front and rear sides of the fixed plates 51. The protective plates 52 and the fixed plates 51 cooperate to form a frame-shaped space, thereby preventing the porcelain insulator from falling during the lifting process. Each protective plate 52 has a handle, which makes it easy for workers to push the sliding plate 53 directly. The sliding plate 53 is slidably connected between the sides of the fixed plates 51 that are close to each other. The sliding plate 53 is used to place the porcelain insulator. The first spring 54 is connected between the sliding plate 53 and the lifting frame 43. The top end of the first spring 54 is connected to the sliding plate 53, and the bottom end of the first spring 54 is connected to the lifting frame 43.

[0031] During the transportation of porcelain insulators, due to their high installation position, strong airflow may blow them during the ascent, potentially causing them to fall. Therefore, fall protection is necessary during transportation. When placing the porcelain insulators, push the front protective plate 52 to the right, then place the porcelain insulator on the sliding plate 53. The sliding plate 53 will slide downwards under the pressure of the porcelain insulator, compressing the first spring 54. Then, push the front protective plate 52 back to its original position to the left, thus protecting the porcelain insulator. The insulator is surrounded and protected. When the porcelain insulator is transported to a high place, the worker is facing the rear protective plate 52. Therefore, the worker only needs to push the rear protective plate 52 to the right and then remove the porcelain insulator. After the porcelain insulator is removed, the sliding plate 53 is no longer compressed and slides upward to reset under the action of the first spring 54. Then, the rear protective plate 52 is pushed to the left to return to its original position. In summary, the protective plate 52 and the fixed plate 51 cooperate to form a frame-shaped protective space, which prevents the porcelain insulator from falling during transportation and improves the protection effect of the porcelain insulator.

[0032] like Figure 1 and Figure 4 As shown, it also includes a stabilizing mechanism 6, which includes a first fixed base 61, a locking member 62, and a stabilizing plate 63. The first fixed block 3 is connected to the front of the first fixed base 61, and the locking member 62 is rotatably connected to the first fixed base 61. The stabilizing plate 63 is slidably connected to the base 1. The stabilizing plate 63 can increase the contact area between the base 1 and the ground, thereby improving the placement stability of the base 1. The locking member 62 can limit the stabilizing plate 63, thereby preventing the stabilizing plate 63 from sliding due to shaking.

[0033] After the base 1 is placed stably, due to the relatively high height of the mounting rod 2, it is necessary to lower its center of gravity to improve its stability. Therefore, the clamp 62 needs to be flipped upwards to open it, so that the stabilizing plate 63 is no longer restricted. Then, the stabilizing plate 63 is pulled forward to increase the contact area between the base 1 and the ground, thereby improving the stability of the base 1 and lowering the center of gravity of the mounting rod 2. After the porcelain insulator is installed, the stabilizing plate 63 is pushed backwards to reset, and then the clamp 62 is flipped downwards to reset and limit the stabilizing plate 63 to prevent it from accidentally slipping out. In summary, by pulling the stabilizing plate 63 forward, the contact area between the base 1 and the ground is increased, making the base 1 more stable and lowering the center of gravity of the mounting rod 2, thus improving its stability.

[0034] like Figure 1 and Figure 5 As shown, it also includes a lifting mechanism 7, which includes a second fixed seat 71, a lifting frame 72, a sliding handle 73, and torsion springs 74. The second fixed seat 71 is bolted to the right side of the lifting frame 43. The lifting frame 72 is rotatably connected to the second fixed seat 71. The lifting frame 72 can push the bottom of the sliding plate 53, thereby causing the sliding plate 53 to slide upward. Two torsion springs 74 are connected between the lifting frame 72 and the second fixed seat 71. The torsion springs 74 are both wound around the second fixed seat 71. The ends of the torsion springs 74 that are close to each other are connected to the second fixed seat 71, and the ends of the torsion springs 74 that are far apart from each other are connected to the lifting frame 72. The sliding handle 73 is slidably connected to the right side of the lifting frame 72. The sliding handle 73 can change the lever arm length, thereby making it easier to press the lifting frame 72.

[0035] If the porcelain insulator is too heavy, it may press the sliding plate 53 downwards a considerable distance, making it difficult for workers to remove the insulator directly. In this case, the sliding handle 73 can be pulled out to the right and then pressed down, causing the lifting frame 72 to rotate clockwise. The torsion spring 74 will deform under force, pushing the sliding plate 53 upwards. As the sliding plate 53 slides upwards, the porcelain insulator will be lifted, making it easier for workers to remove it directly. Once the porcelain insulator is removed, the worker can release the sliding handle 73. Under the action of the torsion spring 74, the lifting frame 72 will rotate counterclockwise to reset. At this point, the lifting frame 72 will no longer push the sliding plate 53. Finally, the sliding handle 73 can be pushed to the left to return to its original position. In summary, by pulling out the sliding handle 73 to change the lever arm, the force required for the worker to press the sliding handle 73 is reduced, and then the lifting frame 72 pushes the sliding plate 53 upwards, making it easier for the worker to remove the porcelain insulator.

[0036] like Figure 1 and Figure 6As shown, it also includes a fixing mechanism 8, which includes a fixed half-ring 81, a rotating half-ring 82, and a locking member 83. Two fixed half-rings 81 are connected to the rear side of the mounting rod 2. The fixed half-rings 81 are symmetrically distributed vertically. Each fixed half-ring 81 is rotatably connected to a rotating half-ring 82. The rotating half-rings 82 cooperate with the fixed half-rings 81 to be installed on the utility pole. Each fixed half-ring 81 is connected to a locking member 83 on its left side. The locking member 83 can lock and fix the corresponding rotating half-ring 82.

[0037] When using this device to transport porcelain insulators, in order to ensure the stability of the mounting rod 2, it is necessary to release the locking member 83 from the locking half ring 82, and then rotate the rotating half ring 82 clockwise to open it. After the fixed half ring 81 is in contact with the utility pole, rotate the rotating half ring 82 counterclockwise to close it. Then, use the locking member 83 to lock and fix the rotating half ring 82, thereby installing the mounting rod 2 on the utility pole.

[0038] like Figure 1 and Figure 7 As shown, it also includes a locking mechanism 9, which includes a sliding block 91, a second fixing block 92, and a second spring 93. The right side of the fixing plate 51 on the right side is connected to the second fixing block 92, and the sliding block 91 is slidably connected to the second fixing block 92. The protective plate 52 can push the sliding block 91. Two second springs 93 are connected between the sliding block 91 and the second fixing block 92. The side of the second springs 93 that are close to each other is connected to the second fixing block 92, and the side of the second springs 93 that are far apart from each other is connected to the sliding block 91.

[0039] When placing the porcelain insulator, the front protective plate 52 needs to be pushed to the right to open. This causes the front protective plate 52 to press and push the sliding block 91 backward, compressing the front second spring 93 and stretching the rear second spring 93. The sliding block 91 then blocks the rear protective plate 52, preventing it from accidentally sliding open. After placement, the front protective plate 52 is pushed to the left to reset. The sliding block 91 is no longer compressed and, under the action of the second spring 93, slides forward to reset. When workers need to remove the porcelain insulator from a height, this is necessary. The rear protective plate 52 pushes the sliding block 91 forward, compressing the rear second spring 93 and stretching the front second spring 93. At this time, the sliding block 91 blocks the front protective plate 52, preventing it from accidentally sliding open. After removal, as the rear protective plate 52 is pushed back into place, the sliding block 91 will also slide back to its original position under the action of the second spring 93. In summary, by pushing the sliding block 91 with the protective plate 52, the other protective plate 52 is blocked, preventing the unopened protective plate 52 from accidentally sliding open and causing the porcelain insulator to fall accidentally.
