Description

Technical Field

[0001] The invention relates to the technical field of power line engineering, and in particular to an assembled aluminum-steel hybrid spanning enclosure frame. Background Art

[0002] During the construction of power lines, it is very common to see lines crossing, especially in the construction of UHV power lines. Therefore, the wire pulling and laying process is crucial. During construction, the wires often need to cross rivers, highways, railways and other objects, so the crossing wire laying operation becomes a key link to ensure construction safety.

[0003] At present, the construction of on-site crossing frames mainly uses bamboo poles, wooden poles or steel pipes and other materials to build dense cross-sections in the vertical, horizontal and diagonal directions, and during the assembly operation, each intersection needs to be fixed by buckles or wire binding. This method has many disadvantages. First of all, a large number of manual handling and assembly operations are not only time-consuming and labor-intensive, but also seriously affect the construction progress. Not only does it extend the construction time, but it also delays the progress of the entire project and increases the cost of the project. Secondly, bamboo poles and wooden poles are easily affected by the natural environment. Problems such as decay, insect bites, and cracking will reduce the strength and stability of the crossing frame, posing a safety hazard to the construction.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] The embodiment of the present application discloses an assembled aluminum-steel hybrid spanning enclosure frame.

[0034] Please refer to Figures 1 to 10 In one embodiment of the present application, an assembled aluminum-steel hybrid span sealing grid frame includes a tower assembly frame 100, at least one tower assembly frame 100 is arranged on both sides of the spanned object 900, and the specific number of the tower assembly frames 100 can be set according to actual construction requirements. In this embodiment, two tower assembly frames 100 are taken as an example. The two tower assembly frames 100 located on one side of the spanned object 900 are slidably connected with the same cross arm assembly frame 200, and a top sealing net 300 is connected between the cross arm assembly frames 200 located on both sides of the spanned object 900. A locking device 400 is arranged between the tower assembly frame 100 and the cross arm assembly frame 200. A first lifting mechanism 500 is detachably connected to the top of the tower assembly frame 100, and a second lifting mechanism 600 is detachably connected to the cross arm assembly frame 200. The first lifting mechanism 500 is used to lift and lower the cross arm assembly frame 200, and the second lifting mechanism 600 is used to disassemble and lift the tower assembly frame 100.

[0035] During use, it is only necessary to first fix the tower assembly frame 100 part on the ground, then install the cross arm assembly frame 200 on the tower assembly frame 100, and then fix the first lifting mechanism 500 on the top of the fixed part of the tower assembly frame 100. The cross arm assembly frame 200 can be pulled up to a set height by using the first lifting mechanism 500, and then the cross arm assembly frame 200 can be fixed and locked on the tower assembly frame 100 by using the locking device 400. At this time, the first lifting mechanism 500 can be temporarily disassembled, and then the first lifting mechanism 500 on the cross arm assembly frame 200 can be used. The second lifting mechanism 600 can lift the other part of the tower column assembly frame 100 to the top of the fixed part of the tower column assembly frame 100 for installation. At this time, the first lifting mechanism 500 is fixedly installed on the top of the new fixed part of the tower column assembly frame 100, and the cross arm assembly frame 200 is lifted by the first lifting mechanism 500. In this way, the tower column assembly frame 100 and the cross arm assembly frame 200 can be easily installed to the set height through a cyclic operation, and the top sealing net 300 can be installed between the two cross arm assembly frames 200 to conveniently complete the construction of the crossing frame.

[0036] This can avoid the use of dense pipes for vertical, horizontal, and diagonal cross-construction, which not only reduces the amount of transportation but also simplifies the cumbersome assembly operations, so that the span frame can be built and dismantled more efficiently; it also reduces the time of high-altitude operations, thereby reducing the risk of falling from heights, which is conducive to ensuring the construction safety of the span frame. It can also avoid the use of large-scale lifting equipment for auxiliary lifting operations during disassembly and assembly, effectively reducing construction costs. At the same time, the tower column assembly frame 100 and the cross arm assembly frame 200 are made of an aluminum-steel hybrid structure to prevent the span frame from being affected by the natural environment during use and causing problems such as decay, insect bites, and cracking, thereby ensuring the strength and stability of the span frame during use.

[0037] Please refer to Figures 1 to 10 In one embodiment of the present application, a tower column assembly frame 100 includes a steel base 101, to which a fixed steel frame 102 is detachably connected by bolt connection, to which a rotating frame 103 is detachably connected by bolt connection, to which a plurality of vertically arranged assembly aluminum frames 104 are sequentially connected, and the assembly aluminum frames 104 can be rotated relative to the fixed steel frame 102 by means of the rotating frame 103, and a first lifting mechanism 500 is detachably installed on the top of the assembly aluminum frame 104 at the top layer. When the construction site of the span frame is accessible to large-scale lifting equipment, the fixed steel frame 102 can be fixedly installed on the ground using the steel base 101, and then the rotating frame 103 can be installed on the fixed steel frame 102, and then multiple assembly aluminum frames 104 can be installed on the rotating frame 103 in sequence in a direction parallel to the ground according to the designed height, and then the assembly aluminum frame 104 can be directly lifted by large-scale lifting equipment and rotated with the rotating frame 103 as the center until it overlaps with the fixed steel frame 102, so that the assembly of the tower column assembly frame 100 can be quickly completed. In this way, the tower column assembly frame 100 can be installed on the ground, and the assembly aluminum frame 104 can also be disassembled on the ground, reducing the duration and risk of high-altitude operations.

[0038] Please refer to Figures 1 to 10 In one embodiment of the present application, the rotating frame 103 includes a fixed seat 1031, which is detachably connected to the top of the fixed steel frame 102, and a swing seat 1032 is hingedly connected to one side of the fixed seat 1031. A first locking hole 1033 is provided on the side of the swing seat 1032 away from the hinged connection, and a second locking hole 1034 is provided on the top of the fixed seat 1031 corresponding to the first locking hole 1033.

[0039] During the construction process, when the construction site of the span frame is convenient for large-scale lifting equipment to arrive, the steel base 101 can be fixedly installed on the ground and then the fixed steel frame 102 can be fixedly installed, and then the cross arm assembly frame 200 can be installed on the fixed steel frame 102, and then the fixed seat 1031 of the rotating frame 103 can be fixedly installed on the fixed steel frame 102, and then the swing seat 1032 can be swung to a direction parallel to the ground, and then a plurality of assembled aluminum frames 104 can be installed on the swing seat 1032 in sequence according to the designed height, and the first lifting mechanism 500 can be fixedly installed on the top of the tower column assembly frame 100, and then the plurality of assembled aluminum frames 104 that are swung to a direction parallel to the ground can be lifted by using external large-scale lifting equipment, so that the swing seat 1032 can be closed toward the fixed seat 1031, and then the tower column assembly frame 100 can be swung to a vertical state, and then bolts or other connecting parts can be used to lock and connect through the first locking hole 1033 and the second locking hole 1034, so that the installation construction of the tower column assembly frame 100 can be completed conveniently and quickly.

[0040] The first lifting mechanism 500 can then be used to lift the cross arm assembly frame 200 until the cross arm assembly frame 200 is lifted to a set height, and then the locking device 400 is used to fix and lock the cross arm assembly frame 200 on the tower assembly frame 100 to conveniently complete the installation of the cross arm assembly frame 200.

[0041] In this way, the tower column assembly frame 100 can be installed directly on the ground, which not only further reduces the time for workers to perform high-altitude operations, but also further improves the work efficiency and safety of the installation construction of the span frame.

[0042] Please refer to Figures 1 to 10 In one embodiment of the present application, the cross arm assembly frame 200 includes a sliding steel frame 201 which is sleeved on the outside of the tower column assembly frame 100, and the outer side surface of the sliding steel frame 201 is detachably connected with a plurality of cantilever aluminum frames 202 in sequence, and the top sealing net 300 is suspended between the cantilever aluminum frames 202 of the two groups of cross arm assembly frames 200, and the outermost cantilever aluminum frame 202 is detachably connected with an obliquely arranged gear rod 203.

[0043] The sliding steel frame 201 can provide a stable and reliable installation foundation for the cantilever aluminum frame 202. The overall length of the cross arm assembly frame 200 can be changed by changing the number of installed cantilever aluminum frames 202. In this way, the overall length of the cross arm assembly frame 200 can be more flexibly configured according to actual construction needs. In addition, the setting of the gear rod 203 on the cantilever aluminum frame 202 can further ensure that the cantilever aluminum frame 202 and the top sealing net 300 can block and gather the crossing wires during use, thereby ensuring the safety of the wire traction and deployment construction process.

[0044] Please refer to Figures 1 to 10In one embodiment of the present application, the inner side surface of the sliding steel frame 201 is located at the upper and lower ends thereof and is fixedly connected to the outer edge of the tower column assembly frame 100 with a roller support 204, and the roller support 204 is rotatably connected to a roller 205, and the roller 205 abuts against the outer edge of the tower column assembly frame 100.

[0045] During the use of the crossing frame, the use of the roller 205 can not only ensure that the sliding steel frame 201 slides more stably and reliably on the outside of the tower assembly frame 100, thereby improving the smoothness of the first lifting mechanism 500 to lift the cross arm assembly frame 200, but also reduce the wear between the sliding steel frame 201 and the tower assembly frame 100, thereby ensuring the service life of the sliding steel frame 201 and the tower assembly frame 100.

[0046] Please refer to Figures 1 to 10 In one embodiment of the present application, the locking device 400 includes a first mounting plate 401 fixedly connected to the inner side of the sliding steel frame 201 and a second mounting plate 402 fixedly connected to the assembly aluminum frame 104. The first mounting plate 401 is provided with a plurality of third locking holes 403, and the second mounting plate 402 is provided with a plurality of fourth locking holes 404 corresponding to the third locking holes 403. The third locking holes 403 and the fourth locking holes 404 can be used to simply and reliably fix the sliding steel frame 201 to the assembly aluminum frame 104 by bolt locking, thereby ensuring the convenience and reliability of the locking device 400 during operation.

[0047] Please refer to Figures 1 to 10 In one embodiment of the present application, the locking device 400 also includes a diagonal brace rod 405, one end of the diagonal brace rod 405 is fixedly connected to a first fixed plate 406, and the other end of the diagonal brace rod 405 is hingedly connected to a second fixed plate 407, a third fixed plate 408 is fixedly connected to the first fixed plate 406 on the assembly aluminum frame 104, and a fourth fixed plate 409 is fixedly connected to the second fixed plate 407 on the cross arm assembly frame 200, and a fifth locking hole 410 is provided on the first fixed plate 406, the second fixed plate 407, the third fixed plate 408, and the fourth fixed plate 409.

[0048] During use, the use of the diagonal brace rod 405 can not only significantly improve the stiffness of the span frame under strong winds, prevent the cross arm assembly frame 200 from swinging too much, and ensure its stability; it can also provide effective support and constraints between the cross arm assembly frame 200 and the tower assembly frame 100, change the stress state of the structure, improve the overall stability of the structure, and prevent structural instability; it also optimizes the overall structural force distribution of the span frame during use.

[0049] Please refer to Figures 1 to 10In one embodiment of the present application, the first lifting mechanism 500 includes a first mounting seat 501, which is detachably mounted on the top of the tower assembly frame 100, and a symmetrically arranged first pulley 502 is rotatably connected to the first mounting seat 501, and a first cable 503 is detachably connected to the cross arm assembly frame 200, and the outer side of the first cable 503 is slidably connected to the first pulley 502, and one end of the first cable 503 away from the cross arm assembly frame 200 is transmission-connected to a first winch device. By using the first winch device, the first cable 503 can be retracted and released, and the first cable 503 will slide on the first pulley 502 and drive the cross arm assembly frame 200 to be lifted and lowered. In this way, by controlling the operation of the first winch device, the height position of the cross arm assembly frame 200 can be accurately adjusted, and flexible lifting and lowering operations can be achieved to meet the construction requirements of the span frame.

[0051] During use, the support rod 602 can be conveniently rotated by utilizing the rotation connection between the support rod 602 and the second mounting seat 601. When the support rod 602 is rotated upward, the second pulley 606 on the support rod 602 can be higher than the cross arm assembly frame 200 to facilitate the hoisting of the assembled aluminum frame 104. When the support rod 602 is rotated downward, the second pulley 606 on the support rod 602 can be lower than the cross arm assembly frame 200 to facilitate the installation of the top sealing net 300. And when the support rod 602 is rotated to an upward state, the sixth locking hole 604 is The sixth locking hole 604 will be able to align with the seventh locking hole 605 located at the lower side of the rotation center of the second mounting seat 601 and the support rod 602. When the support rod 602 is rotated to a downward state, the sixth locking hole 604 will be able to align with the seventh locking hole 605 located at the upper side of the rotation center of the second mounting seat 601 and the support rod 602. In this way, the second mounting seat 601 and the rotating seat 603 can be locked together by using bolts, avoiding the disassembly of the support rod 602 at a high place, which is beneficial to improving work efficiency and ensuring construction safety. The second hoisting device can retract and release the second cable 607, and the second cable 607 will slide on the second pulley 606 and drive the assembly aluminum frame 104 to rise and fall. In this way, by controlling the operation of the second hoisting device, the height position of the assembly aluminum frame 104 can be accurately adjusted, and flexible lifting and lowering operations can be achieved to meet the installation and construction requirements of the tower column assembly frame 100.

[0053] During use, the anchor device 700 disposed on the outside of the tower assembly frame 100 can be used to fix the tower assembly frame 100 to the ground through the pull rope 702, providing lateral tension for the tower assembly frame 100 to prevent it from tilting or shaking during use. At the same time, the first anchor plate 701 and the second anchor plate 703 can be detachably connected, which is convenient for assembly and adjustment, and is conducive to improving construction efficiency; during the working process, the pull rope 702 provides lateral support for the tower assembly frame 100, effectively improving the stability of the tower assembly frame 100, ensuring safe use under various working conditions, and can also adjust the length and anchoring position of the pull rope 702 according to different terrains and construction conditions to meet different engineering requirements.

[0055] During use, when the crossing frame is subjected to crosswind or other unexpected situations and swings or deflects greatly, the pull rope 702 will pull the pull rod 803 and then drive the piston body 802 to slide inside the cylinder 801. After the position of the piston body 802 changes, the pressure inside the monitoring tube 804 will also change. After the pressure inside the monitoring tube 804 changes, it will drive the elastic membrane 805 to bulge or sink along the axis of the monitoring tube 804. The elastic membrane 805 will drive the electrode column 806 to contact any one of the contacts 808 and trigger the alarm 807 to send an alarm signal. This will allow construction personnel to know the abnormal state of the crossing frame at the first time, so as to quickly take countermeasures to avoid further expansion of the danger. It is also beneficial to remind on-site personnel to stay away from dangerous areas and prevent accidents such as falling objects and collapse caused by the swinging or deflection of the crossing frame from causing harm to personnel.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
