Description

Technical Field

[0001] This utility model relates to the field of power operation protection devices, and more specifically, to a device for preventing personnel from falling from a tower when mounted on a drone. Background Technology

[0002] Power towers are critical power facilities. Depending on the level of the transmission and distribution lines, power towers carry a large number of power equipment and electrical components. They are also places where faults frequently occur and maintenance is required. Therefore, power maintenance often requires workers to climb power towers.

[0003] The first type of protective measures used during climbing involves using tools such as double extension ropes and double-hook fall arrestors. However, these tools alter the workers' original climbing habits, leading to greater physical exertion and increasing the risk of falls. Therefore, power maintenance workers are not keen on using these tools. The second type involves installing fall-prevention ladders, fall-prevention rails, and fall-prevention steel strands. However, these devices require power outages for installation, are costly and require significant investment, and are difficult to maintain, hindering widespread adoption. Utility Model Content

Detailed Implementation

[0026] Various embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0027] This utility model provides a drone-mounted tower climbing device to prevent personal fall. See [link / reference] Figures 1 to 4The drone-mounted tower climbing and fall protection device includes: a jointed bracket 1, a mounting assembly, a locking assembly, and an attachment point assembly. The upper end of the jointed bracket 1 is connected to the drone, the mounting assembly is connected to the lower end of the jointed bracket 1, and the locking assembly is located on the mounting assembly. The attachment point assembly includes a bracket assembly and a fastening assembly mounted on the bracket assembly. The fastening assembly is detachably connected to the mounting assembly via the locking assembly. The bracket assembly is used to hang on the angle steel of the power tower. The bracket assembly is equipped with a first gas supply assembly, a first transmission assembly, and a first limiting assembly. The first limiting assembly is slidably connected to the bracket assembly and connected to the first transmission assembly. The first transmission assembly is connected to the first gas supply assembly, and one end of the first gas supply assembly is located at the connection between the fastening assembly and the bracket assembly. When the drone rotates the fastening assembly, gas flows between the first gas supply assembly and the first transmission assembly, causing the first transmission assembly to drive the first limiting assembly closer to or away from the horizontal part of the angle steel of the power tower.

[0028] Specifically, the mounting bracket assembly is connected to a fall arrestor rope (not shown in the figure). The drone carries the attachment point assembly via the joint sling 1 and the mounting assembly, hooking the mounting bracket assembly onto the angle steel of the power tower. This eliminates the need for personnel to climb the tower for pre-installation during power outages, avoiding the safety risks associated with installation during power outages and personnel climbing the tower. Installation is more flexible and operational safety is improved. Furthermore, the first air supply assembly, first transmission assembly, and first limiting assembly on the mounting bracket assembly automatically limit the mounting bracket assembly suspended on the angle steel of the power tower, preventing displacement of the mounting bracket assembly on the angle steel and improving safety during use.

[0029] The mounting assembly has a hook-shaped structure, including a crossbeam 601 and a front bracket 602 and a rear bracket 603 fixedly connected to both ends of the crossbeam 601. A threaded sleeve 604 is provided on the top of the crossbeam 601, and a guide rod 605 is obliquely provided on the front bracket 602. The first limiting assembly is slidably connected to the guide rod 605. The fastening assembly includes a ball head 701, a bolt 702 fixed to the lower end of the ball head 701, and a hanging ring 703 movably connected to the ball head 701. The hanging ring 703 is detachably connected to the mounting assembly through the locking assembly. The bolt 702 is threadedly connected to the threaded sleeve 604. The UAV can drive the ball head 701 and the bolt 702 to rotate through the joint bracket 1, the mounting assembly, and the hanging ring 703.

[0030] The mounting assembly includes a mounting head 201 and two mounting brackets 202. The mounting head 201 is fixedly connected to the lower end of the joint hanger 1. A locking groove 203 is provided at the lower end of the mounting head 201. The two mounting brackets 202 are symmetrically arranged at the lower end of the mounting head 201, and are inclined in a V-shape at the lower end of the mounting head 201, and are symmetrically arranged with respect to the center of the mounting head 201. The locking assembly is installed in the mounting head 201. The locking assembly includes a motor 301, a driving gear 302, a driven gear 303, a screw 304, and a locking block 4. The motor 301 is fixedly connected to the mounting head 201. Gear 302 is fixedly connected to the output shaft of motor 301. Driven gear 303 is rotatably connected to mounting head 201 and meshes with driving gear 302. Screw 304 is coaxially fixed to driven gear 303. Locking block 4 is threadedly connected to screw 304. Mounting head 201 is provided with a locking slot 5 that spans the locking groove 203. Locking block 4 is slidably disposed in locking slot 5. Motor 301 is used to drive driving gear 302 to rotate. Driving gear 302 is used to drive driven gear 303 and screw 304 to rotate. Screw 304 is used to drive locking block 4 to move in locking slot 5, thereby locking and fixing hanging ring 703 inserted into locking groove 203.

[0031] By providing two V-shaped inclined mounting brackets 202 at the lower end of the mounting head 201, the hanging ring 703 of the fastening component can be smoothly guided into the locking groove 203 at the lower end of the mounting head 201 when the mounting component is connected to the fastening component. After the hanging ring 703 enters the locking groove 203, the motor 301 is started, driving the drive gear 302 to rotate. Through the meshing transmission with the driven gear 303, the screw 304 is controlled to rotate. The rotation of the screw 304 drives the locking block 4 to move in the locking slot 5. The locking block 4 passes through the hanging ring 703 in the locking groove 203. The two ends of the locking block 4 are respectively located in the locking slots 5 on both sides of the locking groove 203, thereby limiting the hanging ring 703 and locking the hanging ring 703 in the locking groove 203. In this embodiment, the cross-section of the locking slot 5 is rectangular, and correspondingly, the cross-section of the locking block 4 is also rectangular, matching the cross-section of the locking slot 5. The drone uses the joint gantry 1 and the mounting assembly to lift the mounting point assembly into the corresponding installation position on the power tower, so that the crossbeam 601 in the mounting assembly is tightly against the horizontal part of the angle steel, and the front bracket 602 and the rear bracket 603 in the mounting assembly abut against the two sides of the angle steel. By controlling the drone to rotate horizontally, the hanging ring 703, the ball head 701 and the bolt 702 are driven to rotate in the threaded sleeve 604. Since the bolt 702 is screwed into the threaded sleeve 604, the downward movement of the bolt 702 can cause the gas in the first gas supply assembly to flow to the first transmission assembly, thereby driving the first limiting assembly to approach the horizontal part of the power tower angle steel and form a limit with the power tower angle steel.

[0032] See Figure 5 and Figure 6 In this embodiment, the mounting head 201 is provided with two bayonets 5 spanning the locking groove 203. The two bayonets 5 are spaced vertically apart, and each bayonet 5 has a locking block 4 slidably disposed therein. Two driven gears 303 are provided, meshing with the upper and lower sides of the driving gear 302 respectively. A screw 304 is coaxially fixed to each of the two driven gears 303, and each screw 304 is threadedly connected to the corresponding locking block 4. By providing two bayonets 5 and locking blocks 4, after the hanging ring 703 enters the locking groove 203, it can be locked and fixed by the upper and lower locking blocks 4, restricting the vertical movement of the hanging ring 703 and making the connection between the hanging point assembly and the mounting assembly more stable and reliable.

[0033] See Figures 7 to 9The first gas delivery assembly includes a first airbag 801 and a first gas delivery pipe 802. The first airbag 801 is disposed within the threaded sleeve 604. One end of the first gas delivery pipe 802 is connected to the first airbag 801, and the other end of the first gas delivery pipe 802 is connected to the first transmission assembly. Gas flows between the first airbag 801 and the first transmission assembly through the first gas delivery pipe 802. The first transmission assembly includes a first air chamber 901, a first plunger 902, a rocker arm 903, a turntable 904, a linkage gear 905, and an output gear 906. The first air chamber 901 is installed within the front bracket 602, and the first plunger 902 is slidably disposed within the first air chamber 901. The rocker arm 903... One end of the rocker arm 903 is rotatably connected to the first plunger 902, and the other end of the rocker arm 903 is rotatably connected to the eccentric position of the turntable 904. The turntable 904 and the output gear 906 are both rotatably connected to the front bracket 602. The linkage gear 905 is coaxially fixed to the turntable 904, and the linkage gear 905 meshes with the output gear 906. When gas flows between the first air bag 801 and the first air chamber 901 through the first air supply pipe 802, it pushes the first plunger 902 to move. The movement of the first plunger 902 drives the rocker arm 903 to swing. The swing of the rocker arm 903 drives the linkage gear 905 fixed to the turntable 904 to rotate. The rotation of the linkage gear 905 drives the output gear 906 meshing with it to rotate. The first limiting assembly includes a slide 1001, a side plate 1002, a top plate 1003, and a first rack 1004. The top plate 1003 and the side plate 1002 are respectively disposed at the upper and lower ends of one side of the slide 1001, and the first rack 1004 is disposed on the other side of the slide 1001. The side plate 1002 is slidably connected to the guide rod 605, and the first rack 1004 meshes with the output gear 906. The output gear 906 rotates to drive the first rack 1004. The movement drives the slide 1001, side plate 1002, and top plate 1003 to move along the guide rod 605; when gas flows from the first airbag 801 into the first air chamber 901, the first transmission component drives the first limiting component to move upward, so that the top plate 1003 of the first limiting component approaches the horizontal part of the power tower angle steel; when gas flows from the first air chamber 901 into the first airbag 801, the first transmission component drives the first limiting component to move downward, so that the top plate 1003 of the first limiting component moves away from the horizontal part of the power tower angle steel.

[0034] Specifically, see Figure 4 and Figure 9The lower end of the front bracket 602 is provided with a triangular mounting portion, within which a mounting cavity is formed for mounting the first transmission component. The first air chamber 901, first plunger 902, rocker arm 903, turntable 904, linkage gear 905, and output gear 906 of the first transmission component are all disposed in this mounting cavity. Two guide rods 605 are provided on the front bracket 602, and correspondingly, two guide holes are provided on the side plate 1002 of the first limiting component. The first limiting component is slidably connected to the two guide rods 605 through the guide holes on the side plate 1002. The front support 602 has a first through groove at its upper end for the top plate 1003 and the slide 1001 of the first limiting assembly to pass through. The width of the side plate 1002 in the first limiting assembly is the same as the width of the front support 602. The included angle between the slide 1001 and the horizontal part of the power tower angle steel is equal to the included angle between the top plate 1003 and the slide 1001, so as to ensure that when the top plate 1003 abuts against the horizontal part of the power tower angle steel, the top plate 1003 can be horizontally attached to the horizontal part of the power tower angle steel. The first airbag 801 has a hollow cylindrical structure and is housed within the screw sleeve 604. A pressure plate can be installed on the screw 304. When the screw 304 rotates downward under the control of the UAV, the pressure plate on the screw 304 compresses the first airbag 801, causing the gas in the first airbag 801 to flow into the first air chamber 901 through the first air supply pipe 802. The first airbag 801 is made of an elastic material. When the screw 304 rotates upward, the first airbag 801 returns to its original shape, allowing the gas in the first air chamber 901 to flow back into the first airbag 801 through the first air supply pipe 802. In a specific implementation, a helical compression spring can also be installed in the first airbag 801 to improve its ability to return to its original shape. A groove can be formed on the slide 1001 so that the first rack 1004 can be embedded in the groove installed on the slide 1001.

[0035] When the control drone rotates, causing the fastening assembly to rotate, the bolt 702 moves downward as it is screwed on. During this process, the first airbag 801 is compressed, causing the gas inside to flow into the first air chamber 901 through the first air supply pipe 802. This causes the first plunger 902 to move and drive the rocker arm 903 to swing. The swing of the rocker arm 903 drives the turntable 904 and the linkage gear 905 to rotate. Under the meshing transmission of the linkage gear 905 and the output gear 906, the output gear 906 rotates and drives the slide 1001 to move along the guide rod 605 on the front support 602 through the first rack 1004 that meshes with it, until the top plate 1003 abuts against the horizontal part of the power tower angle steel. The crossbeam 601 of the bracket assembly and the top plate 1003 of the first limiting assembly form a pressing force on the upper and lower sides of the horizontal part of the power tower angle steel, fixing the bracket assembly to the power tower angle steel.

[0036] Furthermore, the UAV-mounted tower climbing and fall protection device also includes a second gas supply component, a second transmission component, and a second limiting component; the second limiting component is rotatably connected to the rear support 603 of the mounting assembly, the second limiting component is connected to the second transmission component, the second transmission component is connected to the second gas supply component, and one end of the second gas supply component is disposed between the first limiting component and the front support 602; when the first limiting component moves on the mounting assembly, gas flows between the second gas supply component and the second transmission component, and the second transmission component is used to drive the second limiting component to move closer to or away from the vertical part of the angle steel of the power tower.

[0037] See Figure 10 The second air delivery assembly includes a second airbag 1101 and a second air delivery pipe 1102. One end of the second airbag 1101 is disposed on the front bracket 602, and the other end of the second airbag 1101 is disposed on the first limiting assembly. One end of the second air delivery pipe 1102 is connected to the second airbag 1101, and the other end of the second air delivery pipe 1102 is connected to the second transmission assembly. Gas flows between the second airbag 1101 and the second transmission assembly through the second air delivery pipe 1102. The second transmission assembly includes a second air chamber 1201. The second plunger 1202 and the second rack 1203 are provided. The second air chamber 1201 is installed in the rear bracket 603. The second plunger 1202 is slidably disposed in the second air chamber 1201. The second rack 1203 is fixedly connected to the second plunger 1202. The second air chamber 1201 is connected to the second air supply pipe 1102. When gas flows between the second air chamber 1201 and the second air bag 1101 through the second air supply pipe 1102, it pushes the second plunger 1202 to move. The movement of the second plunger 1202 drives the second rack 1203 to move. The second limiting component includes a support plate 1301 and an input gear 1302. The support plate 1301 is rotatably connected to the rear bracket 603 via a rotating shaft. The input gear 1302 is fixedly connected to the rotating shaft of the support plate 1301. The input gear 1302 meshes with the second rack 1203. The movement of the second rack 1203 drives the input gear 1302 to rotate, thereby driving the support plate 1301 to rotate. When gas flows from the second air bladder 1101 into the second air chamber 1201, the second transmission component drives the support plate 1301 to move closer to the vertical part of the power tower angle steel. When gas flows from the second air chamber 1201 into the second air bladder 1101, the second transmission component drives the support plate 1301 away from the vertical part of the power tower angle steel.

[0038] Specifically, in this embodiment, two sets of the second air supply assembly and the second transmission assembly are respectively provided, and the two sets of the second air supply assembly and the second transmission assembly are symmetrically arranged at the midpoint of the width direction of the bracket assembly. By providing two sets of the second air supply assembly and the second transmission assembly, the rotation of the support plate 1301 of the second limiting assembly can be more stable. The support plate 1301 has a plate-shaped structure, and the rear bracket 603 has a second through groove for mounting the support plate 1301. The rotating end of the support plate 1301 is located in the second through groove and is rotatably connected to the rear brackets 603 on both sides of the second through groove via a rotating shaft. The rear brackets 603 on both sides of the second through groove are also provided with mounting grooves for mounting gears and second racks 1203. An input gear 1302 is fixedly connected to each end of the rotating shaft of the support plate 1301, and the meshing input gear 1302 and the second rack 1203 are both located in the mounting groove. The second airbag 1101 is located on the front side of the front bracket 602, between the side plate 1002 of the first limiting assembly and the front bracket 602. When the first limiting assembly moves obliquely upward along the guide rod 605, the side plate 1002 compresses the second airbag 1101, causing the gas in the second airbag 1101 to flow into the second air chamber 1201 through the second air supply pipe 1102. The second airbag 1101 is also made of elastic material. When the first limiting assembly moves obliquely downward, the second airbag 1101 returns to its original shape, causing the gas in the second air chamber 1201 to flow back into the second airbag 1101 through the second air supply pipe 1102. In specific implementations, a compression spring can also be provided in the second airbag 1101 to improve the ability of the second airbag 1101 to return to its original shape. The initial position of the support plate 1301 is vertically downward. When the second rack 1203 in the second transmission assembly moves downward, it drives the input gear 1302 to rotate, thereby changing the support plate 1301 from a vertical state to a horizontal state, thus limiting the vertical part of the power tower angle steel.

[0039] As the first limiting component moves to limit the horizontal portion of the power tower angle steel, the side plate 1002 of the first limiting component squeezes the second airbag 1101, causing the gas inside to flow into the second air chamber 1201 through the second air supply pipe 1102. This causes the second plunger 1202 to move, which in turn drives the second rack 1203 to move. Through the meshing of the second rack 1203 with the input gear 1302, the input gear 1302 is driven to rotate. The input gear 1302 then drives the support plate 1301 to rotate and abut against the vertical portion of the power tower angle steel, further limiting the connection between the bracket assembly and the power tower angle steel.

[0040] The drone-mounted tower climbing and fall protection device can drive the first limiting component to move by rotating the fastening component, forming a limit with the horizontal part of the power tower angle steel to prevent the hanging point component from shifting on the angle steel; the movement of the first limiting component drives the movement of the second limiting component, forming another limiting relationship with the vertical part of the power tower angle steel, further improving the stability of the hanging point component.

[0041] In summary, the drone-mounted tower climbing anti-fall device provided by this utility model can replace manual tower climbing installation by launching it from the air via a drone. The installation of the attachment point components is more efficient and safer, and can be installed without shutting down the power facilities. After use, the attachment point components can be removed using a drone, making it convenient to use.
