Description

Technical Field

[0001] This invention relates to the field of power installation and transmission technology, and more specifically, to a power crossing frame. Background Technology

[0002] In high-altitude power operations, power crossing frames are key equipment for enabling cables to cross obstacles such as ground buildings, roads, and complex terrain between different power towers. Their core function is to use cranes to lift the crossing frame to the air, providing stable crossing and transmission support for the cables and ensuring the smooth progress of power operations.

[0003] When multiple cables are simultaneously transported across existing power crossing frames, the cables, initially separated, easily become entangled and intertwined as the cable installation positions at the tower ends are adjusted, making separation difficult and hindering subsequent installation work. Furthermore, the pressure rollers used to limit cable displacement in existing crossing frames have a fixed height, making it impossible to flexibly adjust the pressure when dealing with cables of different diameters. For thicker cables, excessive pressure from the rollers can cause bending and damage to the cable surface, affecting cable quality. In the event of a sudden cable breakage, the broken end can easily fall directly to the ground (such as on highways or in residential areas), creating a dangerous environment. Human response is often delayed, and traditional check valves can only prevent the cable from slipping off the crossing frame, not retrieve the broken end to a higher altitude. This not only makes secondary cable crossings difficult but also increases the risk of ground safety accidents (such as vehicles being caught in the cable or people being electrocuted). Summary of the Invention

[0004] The purpose of this application is to provide a power crossing frame that solves the problems of easy cross-entanglement and inability to respond promptly and automatically recover cables after breakage during high-altitude multi-cable crossing and transmission.

[0021] Preferably, the baffle is fixed in the middle of the support base, the limiting frame abuts against the baffle when it swings down, and the inner side of the limiting frame abuts against the baffle when it swings towards the slide rod to be parallel to the slide rod.

[0022] Preferably, the outer side of the limiting frame is an inclined surface. When the limiting frame swings outward, the outer inclined surface of the limiting frame abuts against the baffle, and the limiting frames at both ends of the slide rod form a "V" shaped structure.

[0023] Preferably, the inner side of the limiting frame is a plane, the pressure roller is rotatably disposed on the inner plane of the limiting frame, and the pressure roller is parallel to the slide bar.

[0024] The lifting structure includes a clamping plate, an electric cylinder, and a pressure sensor.

[0025] Both ends of the clamping plate are rotatably connected to both ends of the length of the pressure roller.

[0026] The electric cylinder is fixed inside the limiting frame, and the driving end of the electric cylinder is fixedly connected to the clamping plate.

[0027] Preferably, the pressure sensor is clamped and fixed between the driving end of the electric cylinder and the clamping plate, and the pressure sensor is electrically connected to the start-stop control end of the electric cylinder.

[0028] The wire mesh frame includes extension rods, winding drums, perforated plates and card slots.

[0041] [[ID=四十八]]The total length of the pressure roller is consistent with the length of the limiting frame.

[0042] The technical solution of this application has at least the following advantages and beneficial effects:

[0043] This invention enables the limiting frame to swing bidirectionally by setting a rotation drive structure. When idle, the limiting frame forms a "V"-shaped guide structure, which facilitates the guidance of cables that deviate from their positions when the UAV is laying cables, ensuring that the cables fall quickly into the slide bar. During operation, the limiting frame is parallel to the slide bar, and the pressure roller works with the slide bar to limit the height gap of the cables, effectively preventing cross-entanglement when multiple cables are transported simultaneously, ensuring smooth cable transport and improving work efficiency.

[0044] This invention, by incorporating a lifting structure and a pressure sensor, can automatically adjust the height of the pressure roller according to the cable diameter, allowing the pressure roller to apply a constant and appropriate pressure to cables of different specifications. This satisfies the restriction requirements for preventing tangling while avoiding cable bending and damage caused by excessive pressure, significantly improving the protection effect on the cable and ensuring the quality of the finished cable.

[0045] This invention utilizes a displacement drive structure. When a cable breaks, the displacement drive structure quickly drives the pressure roller and the slide bar to form a clamping structure, simultaneously rotating the slide bar to retract the broken end towards the unbroken end, preventing the broken end from remaining on the ground. At the same time, the mesh frame and interception rope first elastically intercept the broken cable, reducing its falling height. If the interception fails, the sensor automatically triggers the recovery function, eliminating the need for manual intervention, significantly shortening the response time, eliminating safety hazards on the ground, and ensuring the safety of the work area and surrounding environment.

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.

It should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Example

[0063] Please refer to Figures 1-14 The present invention provides a power crossing frame for use in high-altitude power operation environments, allowing cables 14 to directly cross ground buildings, roads, terrain, etc., from one power tower to another for normal power operation. It includes a cable crossing frame 2, which is set at the lifting top of a crane 1. The crane 1 uses its lifting end to lift the cable crossing frame 2 to a high altitude, so that the cable crossing frame 2 can provide a cable crossing environment for the cable 14 at high altitude.

[0064] Please refer to Figure 2 and Figure 11 The cable tray 2 includes a support beam 201 and a transverse beam 202. The support beam 201 is a planar frame structure. At least one transverse beam 202 is fixedly installed on the support beam 201. Each transverse beam 202 has a crossing rod structure 5 on its top surface. When the cable 14 is transported across the air, the cable 14 will slide and displace on the crossing rod structure 5.

[0065] The crossing rod structure 5 includes a slide rod 501 and a motor 502. The slide rod 501 is rotatably mounted on the transverse beam 202 and has the same length as the transverse beam 202. One end of the slide rod 501 is coaxially fixedly connected to the motor 502, which is fixed on the transverse beam 202. The surface of the slide rod 501 is set to a smooth surface, and the length direction of the slide rod 501 is perpendicular to the crossing and conveying direction of the cable 14. When the cable 14 is crossed and conveyed, the cable 14 will slide quickly on the slide rod 501 to cross the cable at high altitude.

[0066] Because the cable guide 2 is a planar frame structure, when the cable guide 2 is lifted by the crane 1, the crane 1 itself cannot adjust the planar angle of the cable guide 2. In the actual working environment, the cable guide 2 may not be parallel to the cable 14 being crossed, but there may be an angle, which can easily cause the surface of the cable 14 to be squeezed and worn and broken by the cable guide 2. Moreover, the crane 1 itself has a long lifting time, and it is difficult to adjust the position and angle after lifting. When there is a deviation between the lifted cable guide 2 and the actual crossing position of the cable 14, it is also difficult to adjust its position.

[0067] For the above issues, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 11 In this embodiment, the rotating end of the rotating platform 3 is fixedly connected to the bottom of the supporting beam 201. The bottom of the rotating platform 3 is connected to the lifting top of the crane 1 with an angle adjustment component 4, so that the cable tray 2 can be rotated in plane and adjusted in angle to match the crossing position of the cable 14 in the air.

[0068] The angle adjustment component 4 includes a hydraulic cylinder 41 and a support frame 42. The displacement end of the hydraulic cylinder 41 is hinged to one end of the bottom of the rotating platform 3, and the cylinder body of the hydraulic cylinder 41 is hinged to the top of the crane 1. One end of the support frame 42 is hinged to the other end of the bottom of the rotating platform 3, and the other end of the support frame 42 is fixed to the top of the crane 1. When the displacement end of the hydraulic cylinder 41 extends or retracts, the plane angle of the wire guide 2 will change.

[0069] In actual cable crossing operations, multiple cables 14 are typically crossed simultaneously on the slide bar 501 to allow personnel on both power towers to work concurrently. However, during cable 14 installation on the power towers, the positions of the cables 14 may need to be adjusted or moved. This causes the multiple cables 14 on the same slide bar 501 to initially slide separately without contact, but as the positions of the two ends of the cables 14 change, some cables 14 may cross each other. When parallel cables 14 cross each other, they can easily become entangled, making it difficult to separate the multiple cables 14 and affecting the installation of the cables 14.

[0070] To resolve the aforementioned issues and maintain the normal operation of multiple cables 14, please refer to... Figures 2-7 In this embodiment, a limiting frame 6 is provided on the support beam frame 201 at both ends of the slide rod 501. One end of the limiting frame 6 is installed on the rotation drive structure 7, so that the limiting frame 6 can swing toward the slide rod 501 until it is parallel to the slide rod 501. A pressure roller 8 is also provided under the frame of the limiting frame 6, which can cooperate with the slide rod 501 to limit the height gap of the cable 14 when sliding on the slide rod 501, thereby reducing the situation of cross-entanglement when multiple cables 14 slide.

[0071] Specifically, the rotation drive structure 7 includes a support base 701, a motor 702, and a baffle 703.

[0072] The support base 701 is mounted on the support beam 201. The top of the support base 701 is rotatably connected to one end of the limiting frame 6. The second motor 702 is fixedly mounted on the support base 701. The drive shaft of the second motor 702 is fixedly connected to one end of the limiting frame 6. When the second motor 702 is started, it will drive the limiting frame 6 to swing.

[0073] A baffle 703 is fixedly installed in the middle of the support base 701. When the limiting frame 6 swings downward, the bottom of the limiting frame 6 will abut against the surface of the baffle 703 to prevent the limiting frame 6 from swinging down excessively. The inner side of the limiting frame 6 is flat. When the limiting frame 6 swings to the inner slide rod 501 via the motor 702, its inner side will abut against the surface of the baffle 703, so that the inner plane of the limiting frame 6 and the slide rod 501 remain parallel. A pressure roller 8 is provided on the inner surface of the limiting frame 6. At this time, the pressure roller 8 will also remain parallel to the slide rod 501.

[0074] Please refer to Figure 5 , Figure 7 and Figure 11 The outer frame of the limiting frame 6 is set as an inclined surface. When the crane 1 lifts the cable guide frame 2 to a high altitude, the motor 702 will drive the limiting frame 6 to swing outward until the outer inclined surface of the frame abuts the baffle 703, so that the limiting frame 6 at both ends of the slide bar 501 forms a "V" shape structure. This facilitates the external drone to initially lay the cable 14 on the cable guide frame 2, and makes it easy for the cable 14 that has deviated from its position to fall into the slide bar 501 along the surface of the pressure roller 8 inside the limiting frame 6 for cable crossing and conveying.

[0075] Please refer to Figures 2-7 When the cable 14 begins to cross and be conveyed, the motor 702 will drive the limiting frame 6 to swing inward until the inner plane of the frame abuts the baffle 703, so that the pressure rollers 8 on the inner side of the limiting frame 6 at both ends of the slide rod 501 are parallel to the slide rod 501. At this time, the height of the pressure rollers 8 is lower than the height of the slide rod 501. When the cable 14 slides and is conveyed on multiple slide rods 501, the multiple pressure rollers 8 will press on the cable 14, restricting the height gap of the cable 14, so that the cable 14 cannot swing up and down at the slide rod 501 during the conveying process, thereby maintaining the state that multiple cables 14 will not cross when being conveyed.

[0076] It is worth noting that although the pressure roller 8 prevents multiple cables 14 from crossing and tangling, the diameter of the cables 14 will vary depending on the standard of the power tower construction. When the pressure roller 8 is at a fixed height on the limiting frame 6, the resistance it exerts on the surface of the cable 14 will be greater when facing a thicker cable 14. Some thicker cables 14 will be damaged on the surface due to excessive bending caused by the pressure, which will affect the quality of the cable 14.

[0077] To solve the above problems, please refer to Figure 6 and Figure 7 In this embodiment, a lifting structure 9 is also provided between the limiting frame 6 and the pressure roller 8 to adjust the relative height of the pressure roller 8 on the limiting frame 6.

[0078] Specifically, the lifting structure 9 includes a clamping plate 901, an electric cylinder 902, and a pressure sensor 903.

[0079] The clamping plate 901 is rotatably connected to both ends of the length of the pressure roller 8, allowing the pressure roller 8 to roll freely. The clamping plate 901 is fixedly connected to the drive end of the electric cylinder 902, and a pressure sensor 903 is also clamped and fixed between the drive end of the electric cylinder 902 and the clamping plate 901. The electric cylinder 902 is fixed inside the limiting frame 6, and the pressure sensor 903 is electrically connected to the start and stop control end of the electric cylinder 902.

[0080] When motor 702 drives the limiting frame 6 and the pressure roller 8 inside the frame to be parallel with the slide bar 501, the electric cylinder 902 and pressure sensor 903 will be activated. The electric cylinder 902 pushes the pressure roller 8 down to contact the upper surface of the cable 14, applying force to the cable 14. The pressure sensor 903 will sense this force. When the force exceeds the maximum pressure threshold set by the pressure sensor 903, the pressure sensor 903 will send a pressure signal to the start / stop control terminal inside the electric cylinder 902. After receiving the pressure signal, the start / stop control terminal will stop the electric cylinder 902 from continuing to move down, maintaining the current downward height, so that the downward pressure applied by the pressure roller 8 to the cables 14 of different diameters is a suitable pressure, which can prevent the cables 14 from crossing and prevent overpressure damage to the cables 14.

[0081] In the process of crossing multiple cables 14, different cables 14 may be in different working states: some cables 14 have been installed and fixed between two power towers; some cables 14 are in a sliding state; and some cables 14 are adjusting the position of their ends at the power towers.

[0082] When multiple cables 14 are simultaneously transported across a bridge, their tension varies at high altitudes due to their different operating conditions. However, the entire bridge frame is in a fixed position. Therefore, in actual simultaneous transport of multiple cables 14, the risk of cable breakage due to tension is higher compared to single-cable transport. Thus, emergency safety measures are required for any accidental breakage of a cable 14 during the crossing, ensuring a safe installation environment.

[0083] In traditional cross-pass equipment, when cable 14 suddenly breaks, the broken end of cable 14 will fall directly to the ground or retract and slide to the unbroken end, detaching from the cross-pass. For both situations, manual pulling of cable 14 is generally used to return it to its original position, and a check valve is added at the sliding position to prevent cable 14 from detaching further and to maintain the cable 14 for cross-pass transmission. However, in actual use scenarios, the use of cross-pass to transport cable 14 is generally for temporary emergency power operations on roads (such as highways), buildings (residential buildings), and in the field (steep terrain). The ground conditions are relatively dangerous or have high safety requirements. When cable 14 breaks and falls directly into the ground environment, manual pulling can easily lead to dangerous accidents (such as a high-speed vehicle getting caught in cable 14 on the ground). Using a check valve can only prevent cable 14 from slipping, and cable 14 is still in a dangerous ground environment (such as cable 14 remaining on the highway surface), making it difficult to recover and re-cross, which has certain drawbacks.

[0084] For the above issues, please refer to... Figures 4-7 In this embodiment, a displacement drive structure 10 is also provided between the rotation drive structure 7 and the support beam 201. The displacement drive structure 10 can drive the limiting frame 6 on the rotation drive structure 7 to move in the direction of cable 14 conveying, thereby limiting the planar distance between the frame 6 and the slide bar 501, so that the pressure roller 8 and the slide bar 501 can clamp the cable 14 from top to bottom, stop the broken cable 14 and synchronously roll it up and recycle the broken end of the cable 14, maintaining the safety of the ground environment.

[0085] Specifically, the displacement drive structure 10 includes a transmission chain 1001, a gear 1002, and a motor 1003.

[0086] The bottom of the support base 701 is slidably mounted on the support beam 201 and is fixedly connected to the transmission chain 1001. The two ends of the transmission chain 1001 are respectively meshed on two gears 1002. The two gears 1002 are rotatably mounted on the support beam 201, and one of the gears 1002 is coaxially fixedly connected to the drive shaft of the motor 1003. The motor 1003 is fixed on the support beam 201. When the motor 1003 starts, the support base 701 will move along the conveying direction of the cable 14.

[0087] Please refer to Figure 5 During normal cable 14 crossing and conveying, the limiting frame 6 on the support 701 and the slide bar 501 on the transverse beam 202 are misaligned. At this time, the pressure roller 8 on the limiting frame 6 is lower than the slide bar 501, thereby preventing the sliding and cross-entanglement of multiple cables 14.

[0088] Please refer to Figures 6-14 When cable 14 breaks, in order to prevent cable 14 from slipping off slide bar 501, motor 31003 drives support seat 701 to move laterally toward slide bar 501, so that pressure roller 8 and slide bar 501 are matched vertically. At this time, electric cylinder 902 drives pressure roller 8 to move down, forming a clamping structure with slide bar 501, applying clamping force to cable 14, thereby limiting further slippage of cable 14 and preventing backflow.

[0089] Meanwhile, the pressure sensor 903 located at the electric cylinder 902 senses the clamping pressure. When the clamping pressure exceeds the pressure threshold set in the pressure sensor 903, it will send a pressure signal to stop the start / stop control terminal of the electric cylinder 902, so that the pressure roller 8 stops moving down, maintains the current clamping degree with the slide bar 501, and avoids over-clamping the cable 14, which would damage the cable 14 sheath.

[0090] When motor 31003 starts, motor 1502 connected to slide bar 501 will also start synchronously, causing slide bar 501 to rotate toward the unbroken end of cable 14. When cable 14 is clamped by slide bar 501 and pressure roller 8, cable 14 will be driven by the rotation of slide bar 501 due to the clamping friction resistance, and will move toward the unbroken end, so that the broken end of cable 14 that falls to the ground environment is quickly rolled into the high-altitude environment and separated from the ground environment, maintaining the safety of the ground environment.

[0091] It is worth noting that the height of the baffle 703 is higher than the height of the slide bar 501, so that when the inner plane of the limiting frame 6 is parallel, it is also higher than the slide bar 501. This makes it easier for the pressure roller 8 located on the inner plane of the limiting frame 6 to be initially higher than the slide bar 501 when the cable 14 breaks and the pressure roller 8 is displaced, so as to form an upper and lower clamping structure with the slide bar 501.

[0092] It is worth noting that the total length of the two limiting frames 6 located at both ends of the slide bar 501 is the same as the length of the slide bar 501. This allows the inner planes of the two limiting frames 6 to just cover the entire length of the slide bar 501 when the limiting frames 6 swing to be parallel to the slide bar 501. The total length of the pressure rollers 8 at the inner planes of the limiting frames 6 is also the same as the length of the limiting frames 6. This ensures that there are corresponding pressure rollers 8 throughout the entire length of the slide bar 501, so as to maintain the transmission of cables at different positions on the slide bar 501 and prevent backflow and recovery after breakage.

[0093] In the above embodiments, although the return-stopping and recovery of the broken cable 14 is achieved synchronously by setting the displacement driving structure 10, in the actual working environment, although there are safety officers in the construction environment and installation personnel on the power tower, who can promptly detect the breakage of the crossing cable 14 and respond in a timely manner to perform return-stopping and recovery of the cable 14, there is always a lag in the manual response. Moreover, personnel are prone to negligence and failure to notice, and cannot respond to or detect the breakage of the cable 14 in a timely manner. This greatly prolongs the time that the damaged cable 141 remains in the ground environment, affecting the safety of the ground environment.

[0094] For the above situation, please refer to Figures 5-12 In this embodiment, a mesh frame 11 is also provided at both ends of the cable 14 conveying of the cable frame 2. Several intercepting ropes 12 are provided on the mesh frame 11 to support the cable 14 being conveyed and to assist in intercepting it in case of breakage. The intercepting ropes 12 are wound on the winding structure 13. When the cable 14 breaks, they will intercept the falling cable 14 and reduce its falling height. A sensing sensor 15 is also provided at the end of the intercepting rope 12. When the sensor detects that the end of the intercepting rope 12 has fallen to its maximum extension length, it indicates that the broken end of the cable 14 has not been completely intercepted and the broken end of the cable 14 has contacted the ground environment. At this time, the sensing sensor 15 will send a signal to activate the anti-return and recovery function of the crossing frame equipment.

[0095] Specifically, the space frame 11 includes an extension rod 1101, a drum 1102, a perforated plate 1103, and a slot 1104.

[0096] The winding structure 13 includes a fixed post 1301, a sliding plate 1302, a roller 1303, and a spring 1304.

[0097] Two extension rods 1101 are respectively set at both ends of the slide rod 501 and fixedly connected to the support beam frame 201. Several evenly arranged slots 1104 are opened on the extension rods 1101. The slots 1104 are arranged along the length direction of the extension rods 1101. Perforated plates 1103 are embedded in the slots 1104. A drum 1102 is rotatably set on the extension rods 1101. An intercepting rope 12 is wound on the drum 1102. The same intercepting rope 12 passes through the two corresponding perforated plates 1103 on the extension rods 1101 at both ends of the slide rod 501 at the same time. The passing direction is consistent with the length direction of the slide rod 501, thereby supporting and intercepting the cable 14 that is being transported across.

[0098] On each orifice plate 1103, a fixing column 1301 is vertically connected. A slide plate 1302 is vertically and slidably penetrated through the fixing column 1301. The slide plate 1302 has a "square" structure. The lower plate surface of the "square" structure of the slide plate 1302 is penetrated through the fixing column 1301, and the two ends of a spring 1304 are respectively and fixedly connected to the fixing column 1301 and the lower plate surface of the "square" structure of the slide plate 1302. A roller 1303 is rotatably arranged on the upper plate surface of the slide plate 1302.

[0099] Before the interception rope 12 disengages from the drum 1102 and penetrates into the orifice plate 1103, it will first be wound around the roller 1303 for guiding, reducing the excessive frictional contact between the interception rope 12 and the outside of the drum 1102, the extension rod 1101, etc. when the interception rope 12 disengages from the drum 1102; and the spring 1304 below the roller 1303 will also provide an elastic acting force for the interception rope 12, making both ends of the interception rope 12 tightened by the elastic force and maintaining the net surface interception function.

[0100] Please refer to Figure 11 , when the cable 14 breaks, the broken end of the cable 14 will fall and land on multiple interception ropes 12 corresponding to this end. When the weight of the cable 14 is too heavy, the gravity of the cable 14 will overcome the elastic force at both ends of the interception rope 12, causing the interception rope 12 to elastically fall.

[0101] Please refer to Figures 7-11 , preferably, in the winding structure 13 at the outermost end of the extension rod 1101, no spring 1304 is provided on the fixing column 1301. Therefore, when the cable 14 breaks, the interception rope 12 in the extension rod 1101 elastically intercepts the broken end of the cable 14. When the broken end of the cable 14 falls, the end interception rope 12 closest to the end will synchronously fall under the gravity of the cable 14, forming the same falling height. If the elastic interception of the interception rope 12 in the extension rod 1101 is successful and the broken end of the cable 14 does not fall to the ground environment, the end interception rope 12 will not fully extend; if the elastic interception of the interception rope 12 in the extension rod 1101 is unsuccessful and the broken end of the cable 14 falls to the ground environment, the end interception rope 12 will fully extend and also contact the ground environment.

[0102] The intercepting rope 12 at the end has the same length as the extension rod 1101 at the same height from the ground. A sensor 15 is fixedly installed on the drum 1102 at the end. The sensing head of the sensor 15 corresponds to the position of the drum wall of the drum 1102. When the intercepting rope 12 is fully extended and the intercepting rope 12 is detached from the drum wall of the drum 1102, the sensor 15 will send a non-sensing signal. The sensor 15 is electrically connected to the start / stop control terminal of the motor 1003 of the displacement drive structure 10. The non-sensing signal controls the motor 1003 to start, driving the pressure roller 8 and the motor 502 to perform check return work. This automatically winds up the broken end of the cable 14 that failed to be intercepted and fell to the ground, thereby realizing automatic sensing and automatic check return, improving response speed and improving the safety of the ground environment.
