Description

Technical Field

[0001] This utility model relates to the field of overhead line crossing frame technology, and in particular to an overhead line crossing frame equipped with a windproof reinforcement device. Background Technology

[0002] Overhead line crossing frames are temporary support and protection facilities used in the construction of power transmission lines (such as high-voltage and ultra-high-voltage lines). Their core function is to cross obstacles such as highways, railways, rivers, existing power lines, and buildings during the line erection process, preventing the conductors and ground wires from directly contacting or damaging the objects being crossed, while ensuring construction safety and the accuracy of line erection.

[0003] In existing technologies, overhead line crossing frames equipped with wind-resistant reinforcement devices are key facilities for ensuring the safety of power transmission line construction. These frames typically employ a three-row system constructed using a steel pipe truss structure (such as φ50 seamless steel pipes), with upright spacing controlled at 1.5-2.0 meters and crossbar spacing at 1.2-1.5 meters, forming a rigid frame. Ground-level bracing is installed at the bottom of the frame, secured to the uprights with fasteners to enhance overall lateral resistance. However, in coastal areas with high salt spray (such as the Yangtze River Delta and Pearl River Delta), steel pipe fasteners and wire rope anchors are prone to electrochemical corrosion. Currently, metal components are protected with hot-dip galvanizing and fluorocarbon coating, but the base cannot withstand horizontal wind forces, causing the top to sway and resulting in overall lateral tilting.

[0013] This utility model has the following beneficial effects: 1. In this utility model, first pull the lever, which pulls the connecting block, causing the connecting block to slide the second fixing block and the fixing rod within the fixed seat. During the sliding, the connecting block compresses the spring, and then pulls the connecting plate, causing the connecting plate to rotate along the outer wall of the fixed seat, ensuring that the connecting block always moves horizontally. After the base is placed on the truck bed, the first fixing block on the left and right sides of the top wall of the base is aligned with the fixed seat on the top wall of the truck bed. Then, the lever is released, and the spring quickly rebounds, pushing the connecting block so that the fixing rod is inserted into the insertion hole on the outer wall of the base. The second fixing block is then inserted into the first fixing block. Finally, the insertion rod is inserted into the inner walls of the first and second fixing blocks, and bolts are screwed in. The bolts fix the insertion rod and the second fixing block together, forming a stable connection. This fixes the base to the truck bed, preventing the base from being unable to resist horizontal wind forces, causing the top to sway and resulting in overall lateral tilting.

[0014] 2. In this utility model, the bridge frame and the mounting block slide upward along the outer wall of the platform. Then, the threaded rod is rotated, and the rotation of the threaded rod drives the locking block, causing the locking block to move up and down inside the outer shell. The upward movement of the locking block pulls the rotating shaft, and the rotating shaft pulls the connecting rod, causing the connecting rod to push the support arm. The support arm rotates along the inner wall of the outer shell, thereby allowing the limiting rod on the outer wall of the support arm to be inserted into the limiting hole on the outer wall of the mounting block. The operation is convenient, and it is easy to install and disassemble the bridge frame, improving the convenience of installation and maintenance. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an overhead line crossing frame equipped with a windproof reinforcement device, comprising a base 1. Fixing mechanisms 5 are equidistantly installed on the left and right sides of the outer wall of the base 1, used to fix the base 1. A lifting platform 2 is installed in the middle of the top wall of the base 1, and a rotating mechanism 3 is installed on the top of the lifting platform 2. A platform 4 is fixedly connected to the top of the rotating mechanism 3. A bridge frame 7 is installed on the front side of the outer wall of the platform 4. Multiple installation mechanisms 6 are equidistantly installed on the outer wall of the platform 4, used to facilitate the installation and disassembly of components. The fixing mechanism 5 includes a fixing seat 509, which is equidistantly fixedly connected to the cargo box at the bottom of the base 1. A pull rod 507 is slidably connected to the inner wall of the fixing seat 509, and a connecting block 505 is fixedly connected to the end of the pull rod 507. A fixing rod 504 is fixedly connected to the left side of the outer wall of the connecting block 505. The fixed rod 504 is slidably connected to the inner wall of the base 1. The outer wall of the pull rod 507 is equipped with a spring 506. The front and rear sides of the outer wall of the fixed seat 509 are rotatably connected to the connecting plate 508. The end of the connecting plate 508 is rotatably connected to the outer wall of the connecting block 505. Multiple fixing blocks 1 502 are fixedly connected at equal intervals on the top wall of the base 1. The top wall of the connecting block 505 is fixedly connected to the fixing block 2 503. The fixing block 2 503 is slidably connected to the inner wall of the fixing block 1 502. The inner walls of the fixing block 2 503 and the fixing block 1 502 are equipped with a locking assembly 501. The locking assembly 501 includes a plug rod 5011. The plug rod 5011 is slidably connected to the inner walls of the fixing block 1 502 and the fixing block 2 503. The inner wall of the plug rod 5011 is threadedly connected to a bolt 5012. The lower part of the outer wall of the bolt 5012 is threadedly connected to the inner wall of the fixing block 2 503. Specifically, first pull the lever 507, which pulls the connecting block 505, causing the connecting block 505 to slide within the fixed seat 509 along with the fixing block 503 and the fixing rod 504. During this sliding motion, the connecting block 505 compresses the spring 506. The connecting block 505 then pulls the connecting plate 508, causing it to rotate along the outer wall of the fixed seat 509, ensuring that the connecting block 505 remains horizontal. After placing the base 1 on the truck bed, align the fixing blocks 502 on the left and right sides of the top wall of the base 1 with the fixed seat 509 on the top wall of the truck bed. Then, release the lever 507. The spring 506 will quickly rebound and push the connecting block 505, causing the fixing rod 504 to be inserted into the insertion hole on the outer wall of the base 1. The second fixing block 503 will be inserted into the first fixing block 502. Finally, insert the plug 5011 into the inner wall of the first fixing block 502 and the second fixing block 503, and screw in the bolt 5012. The bolt 5012 fixes the plug 5011 and the second fixing block 503 together, forming a stable connection. This fixes the base 1 to the carriage, preventing the base 1 from being unable to resist the horizontal wind force, causing the top to sway and the whole to tilt to the side.

[0019] Reference Figure 1 , Figure 2 and Figure 5The installation mechanism 6 includes a housing 604, which is fixedly connected to the left and right sides of the outer wall of the platform 4. Mounting blocks 606 are fixedly connected to the left and right sides of the outer wall of the bridge frame 7. Limiting holes 607 are formed on the left and right sides of the outer wall of each mounting block 606. A transmission assembly 601 is installed on the inner wall of the housing 604. The transmission assembly 601 includes a threaded rod 6011, which is threadedly connected to the upper part of the inner wall of the housing 604. A locking block 60 is rotatably connected to the bottom of the threaded rod 6011. 12. The locking block 6012 is slidably connected to the inner wall of the outer shell 604. The inner wall of the locking block 6012 is rotatably connected to the rotating shaft 602. The outer wall of the rotating shaft 602 is equidistantly rotatably connected to multiple connecting rods 603. The inner wall of the outer shell 604 is equidistantly rotatably connected to multiple support arms 608. The top of the support arm 608 is rotatably connected to the inner wall of the connecting rod 603. The lower middle part of the outer wall of the support arm 608 is fixedly connected to the limiting rod 605. The limiting rod 605 is slidably connected to the inner wall of the limiting hole 607. Specifically, the bridge frame 7 and the mounting block 606 are slid upwards along the outer wall of the platform 4. Then, the threaded rod 6011 is rotated, which in turn rotates the transmission block 6012, causing the block 6012 to move up and down within the housing 604. The upward movement of the block 6012 pulls the rotating shaft 602, which in turn pulls the connecting rod 603, causing the connecting rod 603 to push the support arm 608. The support arm 608 rotates along the inner wall of the housing 604, thereby allowing the limiting rod 605 on the outer wall of the support arm 608 to insert into the limiting hole 607 on the outer wall of the mounting block 606. This operation is convenient, facilitating the installation and disassembly of the bridge frame 7 and improving the ease of installation and maintenance.

[0020] Reference Figure 1 , Figure 2 and Figure 3 A cable conveyor 8 is installed on the inner wall of platform 4. The cable conveyor 8 is installed on the rear side of the inner bottom wall of platform 4. Support wheels 9 are installed on the bottom wall of platform 4. The support wheels 9 are installed at equal intervals in the middle of the bottom wall of platform 4. Specifically, when laying overhead lines, manual dragging can easily cause wear on the cable insulation layer, and requires multiple people to work together, which is inefficient. The cable conveyor 8 clamps the cable with two sets of drive wheels and conveys it at an adjustable speed. This can not only prevent the cable from being deformed by pressure, but also ensure stable conveying traction force, greatly reduce manual intervention, and protect the integrity of the cable insulation layer. The support wheels 9 evenly distribute the weight of the platform 4 itself, the weight of the construction personnel and tools, and the weight of the cable conveyor 8, avoiding deformation of the bottom wall of the platform 4 due to concentrated load.

[0021] Working principle: First, pull rod 507, which pulls connecting block 505, causing connecting block 505 to drive fixed block 503 and fixed rod 504 to slide within fixed seat 509. During sliding, connecting block 505 compresses spring 506. Connecting block 505 then pulls connecting plate 508, causing connecting plate 508 to rotate along the outer wall of fixed seat 509, ensuring that connecting block 505 always moves horizontally. Then, after placing base 1 on the truck bed, align the fixed blocks 502 on the left and right sides of the top wall of base 1 with the fixed seat 509 on the top wall of the truck bed. Then, release the lever 507. The spring 506 will quickly rebound and push the connecting block 505, so that the fixing rod 504 is inserted into the insertion hole on the outer wall of the base 1, and the second fixing block 503 will be inserted into the first fixing block 502. Finally, insert the plug 5011 into the inner wall of the first fixing block 502 and the second fixing block 503, and screw in the bolt 5012. The bolt 5012 fixes the plug 5011 and the second fixing block 503 together to form a stable connection, and fixes the base 1 on the carriage to prevent the base 1 from being unable to resist the horizontal wind force, causing the top to sway and the whole to tilt to the side. Slide the bridge frame 7 and mounting block 606 upwards along the outer wall of platform 4, then rotate the threaded rod 6011. The threaded rod 6011 rotates the transmission block 6012, causing the block 6012 to move up and down inside the housing 604. The upward movement of the block 6012 pulls the rotating shaft 602, which in turn pulls the connecting rod 603, causing the connecting rod 603 to push the support arm 608. The support arm 608 rotates along the inner wall of the housing 604, thereby allowing the limiting rod 605 on the outer wall of the support arm 608 to insert into the limiting hole 607 on the outer wall of the mounting block 606. This operation is convenient, facilitating the installation and disassembly of the bridge frame 7 and improving the ease of installation and maintenance.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
