Description
Technical Field
[0001] This invention relates to the field of power grid construction technology, specifically to a convenient and lightweight distribution network crossing frame and its construction method. Background Technology
[0002] Power grid crossing frames are temporary support structures used in power line construction. They are primarily used to cross obstacles such as highways, railways, rivers, and existing power lines, ensuring the safety of conductors and ground wires. Based on materials, they can be categorized into wooden, steel, aluminum alloy, and new composite material frames, with the appropriate type selected according to the type of obstacle being crossed, the span, and the load rating. Construction must strictly adhere to design specifications, involving steps such as foundation reinforcement, pole erection, crossbar connection, and diagonal bracing reinforcement. Anti-tipping and electric shock protection measures must be implemented. After completion, they must be dismantled promptly. Characterized by high flexibility and safety, they are crucial equipment for ensuring that power grid construction does not disrupt the normal operation of existing transportation and energy facilities.
[0003] In the existing technology, power distribution network crossing frames are generally temporary crossing frames that are erected or carried by engineering vehicles.

Detailed Implementation
[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see the appendix Figure 1 - Appendix Figure 11This invention provides a convenient and lightweight power distribution network crossing frame and its construction method, including a tricycle 1. An electric lifting frame 2 is fixedly connected to the top of the tricycle 1. A placement plate 3 is fixedly connected to the top of the electric lifting frame 2. The placement plate 3 provides an installation position. A folding mechanism 4 is provided on the top of the placement plate 3. A protective mechanism 5 is provided at the top of the folding mechanism 4. An adjustment mechanism 6 is provided outside the protective mechanism 5. The folding mechanism 4 is used to fold and store the protective mechanism 5 and the adjustment mechanism 6. The adjustment mechanism 6 is used to support the area and the support angle.
[0020] The folding mechanism 4 includes a sliding groove 401, which provides an installation and sliding position. The sliding groove 401 is formed inside the top of the placement plate 3. A sliding plate 402 is slidably connected inside the sliding groove 401, providing an installation position. A mounting bracket 403 is fixedly connected to the top of the sliding plate 402, providing an installation position. A rotating column 404 is rotatably connected to the inner side of the mounting bracket 403, providing an installation position. Limiting columns 405 are slidably connected to both sides inside the rotating column 404, serving a limiting function. A tension spring 406 is provided inside the limiting column 405. A connecting column 407 is fixedly connected to the end of the limiting column 405 away from the tension spring 406, serving a connecting function. A circular plate 408 is fixedly connected to the end of the connecting column 407 away from the limiting column 405. The circular plate 408 provides an installation position. Two locking columns 409 are fixedly connected to the side of the circular plate 408 near the rotating column 404. Multiple locking slots 410 are opened inside both sides of the mounting bracket 403. After the locking columns 409 are inserted into the locking slots 410, they can prevent the rotating column 404 from rotating. After the locking columns 409 are removed from the locking slots 410, the rotating column 404 can rotate. A fixing rod 411 is fixedly connected to the inner side of the mounting bracket 403. The fixing rod 411 provides an installation position. A rotating sleeve 412 is fixedly connected to the outside of the fixing rod 411. The rotating sleeve 412 provides an installation position. A torsion spring 41 is provided inside the rotating sleeve 412. 4. The torsion spring 414 can drive the rotating sleeve 412 to rotate and reset. The rotating sleeve 412 is fixedly connected to the outside of the hook 413. The placement plate 3 has a hanging groove 415 inside. The end of the hook 413 away from the rotating sleeve 412 is engaged with the hanging groove 415. After the hook 413 is engaged with the hanging groove 415, it can prevent the sliding plate 402 from moving. One end of the tension spring 406 is fixedly connected to the inside of the limiting post 405, and the other end of the tension spring 406 is fixedly connected to the inside of the rotating post 404. One end of the torsion spring 414 is fixedly connected to the inside of the rotating sleeve 412, and the other end of the torsion spring 414 is fixedly connected to the outside of the fixing rod 411. The two connecting posts 407 are rotatably connected to the inside of the two sides of the mounting bracket 403 respectively. The engaging post 409 engages with the engaging groove 410. When the protective mechanism 5 is rotated, the circular plate 408 is first pulled away from the mounting bracket 403, causing the engaging post 409 to disengage from the engaging groove 410. Then, the rotating post 404 can be rotated, causing the limiting post 405 to rotate. The limiting post 405 then rotates the connecting post 407, which in turn rotates the circular plate 408 and the engaging post 409. This rotation of the rotating post 404 rotates the protective mechanism 5, allowing for angle adjustment of the protective mechanism 5 and the adjusting mechanism 6. After angle adjustment, the circular plate 408 is released, and the tension spring 406 pulls the limiting post 405 back to its original position, thereby resetting the connecting post 407 and the circular plate 408.After the circular plate 408 is reset, it can drive the locking pin 409 to move towards the rotating pin 404, thereby allowing the locking pin 409 to insert into the locking groove 410, thus completing the angle adjustment. When the hook 413 is rotated upward, the hook 413 can be released from the locking groove 415. At this time, the protective mechanism 5 is laid horizontally on top of the placement plate 3, and the sliding plate 402 can be slid to the edge of the sliding groove 401, thus completing the folding of the protective mechanism 5 and the adjustment mechanism 6. When the sliding plate 402 slides towards the middle of the placement plate 3, and the end of the hook 413 away from the rotating column 404 contacts the edge of the sliding groove 401, it can rotate upward under the action of the squeezing force. After the hook 413 moves into the hanging groove 415, it can rotate in the opposite direction under the reaction force of the torsion spring 414, thereby causing the hook 413 to engage inside the hanging groove 415, thus preventing the sliding plate 402 from sliding towards the edge of the sliding groove 401.
[0021] The protective mechanism 5 includes a protective cylinder 501, which provides an installation position. The bottom of the protective cylinder 501 is fixedly connected to the outside of the rotating column 404. Two slots 502 are formed on the top outer wall of the protective cylinder 501. A fixing column 503 is fixedly connected to the bottom inside the protective cylinder 501, providing an installation position. A sliding column 504 is slidably connected to the outside of the fixing column 503, providing an installation position. A retaining ring 505 is fixedly connected to the bottom of the sliding column 504, which can compress the push spring 506. A push spring 506 is sleeved on the outside of the column 503. The push spring 506 can push the retaining ring 505 and the sliding column 504 to move upward. The top of the sliding column 504 is rotatably connected to the rotating seat 507, which provides the installation position. Both sides of the rotating seat 507 are rotatably connected to the locking pins 508. The locking pins 508 can move upward inside the rotating seat 507, but cannot rotate downward due to the obstruction of the rotating seat 507. One end of the push spring 506 is fixedly connected to the bottom of the inner end of the protective cylinder 501. The other end of the spring 506 is fixedly connected to the bottom of the retaining ring 505. The outer part of the fixing post 503 is slidably connected to the middle part of the retaining ring 505. When protecting the adjustment mechanism 6, first fold the adjustment mechanism 6 and push it downwards. This allows the retaining ring 505 to compress and push the spring 506. When the locking post 508 moves to the top of the protective cylinder 501, first slide the locking post 508 into the long groove of the locking slot 502 and rotate the rotating seat 507. This allows the locking post 508 to rotate along the annular groove to the short groove of the locking slot 502. When the rotating seat 507 is released, the locking pin 508 can be pushed into the short groove of the locking slot 502 under the reaction force of the pushing spring 506, so that the adjusting mechanism 6 can be placed inside the protective cylinder 501 to protect the adjusting mechanism 6. When the adjusting mechanism 6 is moved out of the protective cylinder 501, simply rotate the rotating seat 507 to release the engagement between the rotating seat 507 and the locking slot 502. Under the reaction force of the pushing spring 506, the retaining ring 505 and the sliding pin 504 can be pushed out of the protective cylinder 501.
[0022] The adjusting mechanism 6 includes a fixed ring 601, which provides the installation position. The middle part of the fixed ring 601 is fixedly connected to the outside of the sliding column 504. Multiple rotating cylinders 602 are rotatably connected to the outside of the fixed ring 601, providing the installation position. Multiple engaging holes 603 are provided on the outer wall of the rotating cylinder 602. A limiting block 604 is slidably connected inside the rotating cylinder 602, which serves as a limiting function. An extension rod 605 is fixedly connected to the end of the limiting block 604 away from the fixed ring 601. The extension rod 605 can extend into the interior of the rotating cylinder 602, thereby extending the rotating cylinder 602. A return spring 606 is provided inside the extension rod 605. The interior of the limiting block 604 slides... A limiting disc 607 is connected, which has a limiting function. A locking head 608 is fixedly connected to the end of the limiting disc 607 away from the return spring 606. The locking head 608 can engage inside the locking hole 603, thereby preventing the limiting block 604 from sliding inside the rotating cylinder 602. A rope-tying hole 609 is provided at the end of the extension rod 605 away from the limiting block 604. A rope can be tied between the two rope-tying holes 609 to support the cable. A pull rod 610 is rotatably connected to the outside of the rotating cylinder 602, which can drive the rotating cylinder 602 to rotate upwards. A sliding ring 611 is slidably connected to the outside of the sliding column 504 above the fixed ring 601, providing an installation position. The top ends of multiple pull rods 610 are rotatably connected to the outer wall of a sliding ring 611. A sliding sleeve 612 is fixedly connected to the top of the sliding ring 611, providing an installation position. Multiple locking plates 613 are rotatably connected inside the sliding sleeve 612. A pressing pad 614 is fixedly connected to the top of the inner side of the locking plate 613. A threaded sleeve 615 is threadedly connected to the outside of the sliding sleeve 612. The threaded sleeve 615 pushes the locking plate 613 to rotate towards the center, thereby using the pressing pad 614 to press the outside of the sliding column 504. One end of the return spring 606 is fixedly connected to the inside of the limiting block 604, and the other end of the return spring 606 is fixedly connected to the end of the limiting plate 607 away from the engaging head 608. The extension rod 605 extends outwards. The rotating cylinder 602 extends to the end furthest from the fixed ring 601. The engaging head 608 engages with the engaging hole 603. When unfolding the adjustment mechanism 6, the threaded sleeve 615 can be screwed downwards first, so that the threaded sleeve 615 no longer presses against the locking plate 613, thus preventing the sliding post 504 from being pressed by the abutment pad 614. This allows the sliding sleeve 612 to slide outside the sliding post 504. Sliding the sliding sleeve 612 downwards allows one end of the pull rod 610 to move downwards, which in turn allows the other end of the pull rod 610 to rotate and unfold the rotating cylinder 602 downwards. The more the rotating cylinder 602 unfolds, the larger the contact area between the top of the crossing frame and the cable. If the contact area is still not large enough...The engaging head 608 can be pressed into the limiting block 604. After the curved surface of the engaging head 608 moves into the engaging hole 603, the extending rod 605 and the limiting block 604 can be pulled outward. When the extending rod 605 is pulled out to the appropriate length, the limiting plate 607 can be reset under the reaction force of the return spring 606, thereby resetting the engaging head 608. Then, the engaging head 608 can be engaged inside the engaging hole 603, thereby extending the extending rod 605 and further expanding the connection between the top of the cross-bracing frame and the cable. To retract the rotating cylinder 602, first slide the extension rod 605 into the interior of the rotating cylinder 602, then twist the threaded sleeve 615 downwards and pull the sliding sleeve 612 upwards. This allows the pull rod 610 to rotate the rotating cylinder 602 upwards, folding it up. After folding, twist the threaded sleeve 615 upwards, pressing it against the locking plate 613. This causes the pressing pad 614 to press against the outside of the sliding post 504, locking the sliding sleeve 612 and completing the folding of the rotating cylinder 602.
[0023] A convenient and lightweight power distribution network crossing frame construction method includes the following steps: Step 1: First, drive the tricycle 1 to the area under the temporary power grid that needs to be set up, and use the folding mechanism 4 to rotate the protection mechanism 5 to a vertical position; Step 2: Pull the adjustment mechanism 6 out from inside the protection mechanism 5 and unfold the adjustment mechanism 6. The adjustment mechanism 6 can be adjusted so that the unfolded area of the adjustment mechanism 6 can be adjusted according to the construction site. Step 3: Start the electric lifting frame 2 to raise it, and use the extended adjustment mechanism 6 to lay the cable, thereby completing the construction of the crossing frame.
[0024] Working principle: When rotating the protection mechanism 5, the circular plate 408 is first pulled away from the mounting bracket 403, causing the locking post 409 to disengage from the locking groove 410. Then, the rotating post 404 can be rotated. The rotation of the rotating post 404 drives the limiting post 405 to rotate, which in turn drives the connecting post 407 to rotate, which in turn drives the circular plate 408 and the locking post 409 to rotate. When the rotating post 404 rotates, the protection mechanism 5 can be rotated, thus completing the angle adjustment of the protection mechanism 5 and the adjusting mechanism 6. After the angle adjustment is complete, the circular plate 408 is released. At this time, the tension spring 406 pulls the limiting post 405 back to its original position, thereby driving the connecting post 407 and the circular plate 408 to reset. After the circular plate 408 resets, it drives the locking post 409 to move towards the rotating post 404, thus enabling the locking post 409 to... Insert the hook 413 into the slot 410 to adjust the angle. When the hook 413 is rotated upward, the hook 413 is released from the slot 415. Then, the protective mechanism 5 is laid horizontally on the top of the placement plate 3. The sliding plate 402 can then be slid to the edge of the sliding groove 401, thus folding the protective mechanism 5 and the adjustment mechanism 6. When the sliding plate 402 is slid to the middle of the placement plate 3, when the end of the hook 413 away from the rotating column 404 contacts the edge of the sliding groove 401, it can be driven to rotate upward under the pressure. When the hook 413 moves into the slot 415, it can be driven to rotate in the opposite direction under the reaction force of the torsion spring 414, thus locking the hook 413 into the slot 415 and preventing the sliding plate 402 from sliding to the edge of the sliding groove 401. When protecting the adjustment mechanism 6, first fold the adjustment mechanism 6 and push it downwards. This allows the retaining ring 505 to compress the push spring 506. When the locking pin 508 moves to the top of the protective cylinder 501, first slide the locking pin 508 into the long slot of the locking groove 502 and rotate the rotating seat 507. This allows the locking pin 508 to rotate along the annular groove to the short slot of the locking groove 502. Then, release the rotating seat 507. At this time, under the reaction force of the push spring 506, the locking pin 508 can be pushed into the short slot of the locking groove 502. This allows the adjustment mechanism 6 to be placed inside the protective cylinder 501, thus protecting the adjustment mechanism 6. When moving the adjustment mechanism 6 out of the protective cylinder 501, simply rotate the rotating seat 507 to release the engagement between the rotating seat 507 and the locking groove 502. Under the reaction force of the push spring 506, the retaining ring 505 and the sliding pin 504 can be pushed out of the protective cylinder 501. When unfolding the adjustment mechanism 6, the threaded sleeve 615 can be turned downwards first, so that the threaded sleeve 615 no longer presses against the locking plate 613, thus preventing the sliding column 504 from being pressed by the abutment pad 614. Then, the sliding sleeve 612 can slide outside the sliding column 504. After sliding the sliding sleeve 612 downwards, one end of the pull rod 610 can move downwards, and then the other end of the pull rod 610 can rotate the rotating cylinder 602 downwards and unfold it. The more the rotating cylinder 602 unfolds, the larger the contact area between the top of the crossing frame and the cable. If the contact area is still not large enough, the engaging head 608 can be pressed into the interior of the limiting block 604. After the curved surface of the engaging head 608 moves into the interior of the engaging hole 603, the extending rod 605 and the limiting block 604 can be pulled outwards. When the extension rod 605 is pulled out to the appropriate length, it can... Under the reaction force of the return spring 606, the limiting plate 607 is reset, which in turn drives the locking head 608 to reset. The locking head 608 then engages inside the locking hole 603, allowing the extension rod 605 to extend. This further expands the contact area between the top of the cross-bracing frame and the cable. When the rotating cylinder 602 is retracted, the extension rod 605 is slid into the rotating cylinder 602, the threaded sleeve 615 is turned downwards, and the sliding sleeve 612 is pulled upwards. This allows the pull rod 610 to rotate the rotating cylinder 602 upwards, causing it to fold. After the rotating cylinder 602 is folded, the threaded sleeve 615 is turned upwards, and the threaded sleeve 615 presses against the locking plate 613, causing the pressing pad 614 to press against the outside of the sliding column 504. This locks the sliding sleeve 612, allowing the rotating cylinder 602 to fold.
