Description

Technical Field

[0001] The utility model relates to the technical field of aerial work protection devices, and in particular to an aerial work anti-fall protection device. Background Art

[0002] The towers of power transmission lines need to be maintained regularly. During the maintenance, workers need to climb the towers to perform high-altitude operations, and they need to wear anti-fall devices when climbing the towers. The suspended anti-fall device is usually temporarily installed and hung on the tower by the first worker who climbs the tower when it is needed. After the work is completed, it is removed by the last worker who descends the tower. In this way, the first climber is not protected by the anti-fall device when climbing the tower and the last climber is not protected by the anti-fall device when descending the tower. The personal safety of each worker cannot be guaranteed, which increases the overall risk factor of tower climbing. Therefore, the method of using drones for mounting has emerged.

[0003] The invention with application number 202310812221.8 discloses an artificial climbing anti-fall protection device. A buffer part is fixedly arranged at the lower end of the boom fixing seat to avoid impact on the drone during the taking-off, landing, hanging and dismantling process; through the three-section hinged boom, even if the wind causes the drone to hover unsteadily, it will not have an adverse effect on the device; two hooks in an eight-shaped shape are arranged, and the slide groove on the upper part of the hook mechanism is in an inverted eight-shaped shape, which greatly reduces the difficulty of hanging and dismantling the device, reduces the dependence on the accuracy of the drone, and is more convenient to use.

[0004] However, the above invention has the following problems: in actual work, the angle irons that bear the load of the anti-fall device in different power transmission line towers are inconsistent in size due to factors such as the construction location or construction process. When the hook is placed on the angle iron, there is a gap between the angle iron and the structural member in the vertical direction of the hook, which causes the hook to be not firmly fixed and prone to shaking, thereby affecting the use of the hanging anti-fall device. Utility Model Content

[0005] The utility model aims to provide an anti-fall protection device for high-altitude operations, which solves the problem that when the existing anti-fall protection device is mounted by using a drone hook, there is a gap between the angle iron and the structural member in the vertical direction of the hook, which causes the hook to be not fixed firmly enough, and after shaking, it affects the use of the hanging anti-fall device.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A high-altitude work anti-fall protection device comprises a hook component and a mounting component detachably connected to the hook component, the mounting component comprises a first support member, a first locking member and a second locking member, the first locking member is rotatably connected to the first support member and the first support member is provided with a first limit member, the mounting component is sleeved with a target through the first support member and the first locking member;

[0008] The first supporting member includes a first frame and a second frame, the second locking member includes a first connecting end and a second connecting end respectively connected to the first frame and the second frame, and the second locking member is used to limit the movement of the mounting component in the horizontal direction.

[0009] The invention with application number 202310812221.8 discloses an artificial climbing anti-fall protection device, in which a buffer part is fixedly arranged at the lower end of the boom fixing seat to avoid the impact on the drone during the lifting and landing hanging and dismantling process; through the three-section hinged boom, even if the wind causes the drone to hover unsteadily, it will not have an adverse effect on the device; two hooks in an eight-shaped shape are arranged, and the slide groove on the upper part of the hook mechanism is in an inverted eight-shaped shape, which greatly reduces the difficulty of hanging and dismantling the device, reduces the dependence on the accuracy of the drone, and is more convenient to use; but the above invention has the following problems: but in actual work, different transmission line towers as supporting stable structures The angle irons may have inconsistent sizes depending on the requirements of different working conditions. When the hook is placed on the angle iron, there is a gap between the angle iron and the structural member in the vertical direction of the hook, which results in the mounting component being not firmly fixed and prone to shaking, thus affecting the use effect of the hanging fall arrester. The utility model provides an anti-fall protection device for aerial work. By adding a second locking member, after the mounting component is placed on the angle iron, the second locking member is used to limit the horizontal movement of the mounting component on the angle iron, thereby eliminating the gap between the angle iron and the mounting component in the horizontal direction, thereby avoiding the problem of the mounting component being unstable and shaking, which affects the use of the hanging fall arrester.

[0010] Furthermore, a slide rail is provided on the first frame, the first connection end is slidably connected to the slide rail and a first connection piece fixed to the slide rail is provided on the first connection end, and the second connection end is rotatably connected to the second frame.

[0011] Since the angle irons in the power line tower that bear the load of the anti-fall device are affected by conditions such as construction, their sizes are inconsistent. According to the parameter information of the line tower, the second locking piece can be directly fixed on the ground and then lifted onto the tower by a drone. However, when the size information of the line tower cannot be accurately known, it is difficult to correctly set the second locking piece. By adopting a sliding connection of the first connection end and a rotating connection of the second connection end, the sliding of the first connection end can enable the second locking piece to automatically move to the corresponding position when mounted, thereby improving the setting flexibility of the second locking piece.

[0012] Furthermore, the second locking member is a telescopic rod.

[0013] The first connection end of the second locking member needs to slide when mounting. Since the second connection end is a rotating connection, the movement trajectory of the first connection end is an arc. Therefore, the slide rail needs to be set as an arc slide rail, which makes the structure of the mounting component complicated. By using a telescopic rod as the second locking member, the slide rail is ensured to be a linear guide rail, thereby reducing the structural complexity of the mounting component, facilitating manufacturing and saving costs.

[0014] Furthermore, the mounting component is fixedly connected with a lifting ring, and the hook component includes a shell, a sliding pin and a controller built into the shell, the shell has a through hole, the sliding pin is slidably connected to the shell through the through hole, and the controller controls the sliding of the sliding pin.

[0015] The mounting parts need to be mounted through a hook and using a drone. By using a controller to control the sliding of the sliding parts, the automatic mounting and removal of the mounting parts can be achieved under unmanned conditions at high altitudes, thereby improving the installation and removal efficiency of the anti-fall protection device.

[0016] Furthermore, the shell includes a first shell part and a second shell part, the first shell part is provided with a slide groove, the second shell part is slidably connected to the first shell part through the slide groove, and a second limiting member for limiting the sliding of the second shell part is fixedly connected to the slide groove.

[0017] There is a controller inside the hook component. To ensure the normal operation of the device, the inside of the hook component needs to be regularly inspected and maintained. By setting the shell of the hook component as a sliding cover, it is convenient for maintenance personnel to disassemble the outer shell of the hook component and repair the internal controller, wires and sliding components. At the same time, by setting a limiter, the problem of the second shell part being separated and lost from the first shell part after sliding open can be avoided.

[0018] Furthermore, there are a plurality of through holes, and the through holes are coaxially distributed in pairs.

[0019] The sliding pin slides along the through hole to achieve installation and disassembly with the lifting ring. When the mounting component and the hook component are connected, the sliding pin is a force-bearing member. By setting a certain number of them and distributing them coaxially in pairs, the carrying capacity of the hook component can be improved to prevent the sliding pin from suddenly breaking due to excessive load during use and causing the device to crash.

[0020] Furthermore, the first supporting member is a hollow structure.

[0021] The first support member is the main part of the mounting component and is also the main load borne by the UAV during transportation. By setting the first support member as a hollow structure, the amount of material used can be reduced while ensuring the structural strength, thereby reducing the overall weight; in addition, the hollow design can also improve the air permeability and thermal insulation performance of the structure, which helps to reduce the impact of thermal expansion caused by heating of the structure; at the same time, the hollow structure can also reduce the contact surface with the external environment, reduce the risk of damage, and extend the service life of the first support member.

[0022] Furthermore, the mounting component is fixedly connected to a first guide frame, and the hook component is fixedly connected to a second guide frame, and both the first guide frame and the second guide frame are in an eight-shaped shape.

[0023] Due to the small size of the lifting ring and the sliding pin, when they are connected at high altitude during the dismantling of the device, the lifting ring and the sliding pin are difficult to position due to the mechanical shaking of the UAV itself or the strong wind at high altitude. By providing an eight-shaped guide frame on both the mounting component and the hook component, the lifting ring and the sliding pin move with the sliding of the eight-shaped guide frame and finally converge accurately, reducing the influence of the environment, UAV performance and the operating level of the UAV operator on the positioning of the lifting ring and the sliding pin, thereby improving the efficiency of mounting and disassembly of the device.

[0024] Furthermore, the first guide frame and the second guide frame are both hollow or hollow structures.

[0025] The guide frame is also the load that the drone needs to bear during its ascent. The purpose of setting the first guide frame and the second guide frame as hollow or hollow structures is to reduce weight, thereby reducing the load on the drone and ensuring that the drone will not affect normal operation due to excessive load.

[0026] Furthermore, the second frame is fixedly connected to a third guide frame, and the third guide frame is arranged at an obtuse angle to the second frame.

[0027] By providing the third guide frame, the guide frame and the left side of the mounting component form an obtuse angle structure, so that the mounting component can be hung on the angle iron more conveniently, reducing the difficulty of hanging.

[0028] One or more technical solutions provided by the utility model have at least the following technical effects or advantages:

[0029] 1. The utility model provides an anti-fall protection device for aerial work. By adding a second locking piece, after the mounting component is placed on the angle iron, the second locking piece is used to limit the horizontal movement of the mounting component on the angle iron, thereby eliminating the gap between the angle iron and the mounting component in the horizontal direction, thereby avoiding the problem of the mounting component being unstable and shaking, which affects the use of the hanging fall arrester.

[0030] 2. The utility model provides an anti-fall protection device for aerial work. By setting the first support member serving as the main structural member of the mounting component as a hollow structure, the amount of material used is reduced while ensuring the structural strength, thereby reducing the overall weight. In addition, the hollow design can also improve the air permeability and heat insulation performance of the structure, and help reduce the impact of thermal expansion caused by heating of the structure. At the same time, the hollow structure can also reduce the contact surface with the external environment, reduce the risk of damage, and extend the service life of the first support member.

[0031] 3. The utility model provides an anti-fall protection device for aerial work. While the second locking member prevents the mounting component placed on the angle iron from shaking left and right in the horizontal direction, a triangular structure is formed between the inclined second locking member and the first supporting member, thereby improving the structural stability of the mounting component.

However, the present invention may also be implemented in other ways different from those within the scope of this description. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

Through the hollow design, the amount of material used can be reduced while ensuring the structural strength, thereby reducing the overall weight; in addition, the hollow design also It can improve the air permeability and heat insulation performance of the structure, help to reduce the impact of thermal expansion caused by heat on the structure. At the same time, the hollow structure can also reduce the contact surface with the external environment, reduce the risk of damage, and extend the service life of the first support member 101. The first locking member 102 is rotatably connected to the first support member 101. The rotatable connection can be a pin connection or a hinge connection. The first support member 101 is provided with a first limiting member 112, and the first limiting member 112 can be a metal or plastic baffle or pin. The mounting component 1 is connected to the target through the first support member 101 and the first locking member 102, that is, when the mounting component is completed, the first support member 101 and the first locking member 102 form a closed frame structure, and the target is in the closed frame structure, and the target includes but is not limited to angle iron structures in the tower of the high-voltage transmission line, building beams or scaffolding crossbars.

[0041] The high-altitude anti-fall protection device provided in the present embodiment is fixedly connected to the drone through the hook component 2. Preferably, the connecting member fixedly connected to the drone can be a plurality of connecting rods connected together by hinges as shown in the figure, so as to ensure that the anti-fall protection device will not shake significantly when the drone is unstable due to wind. The anti-fall protection device is lifted to above the target position by the drone, and the drone descends at this time. During the descent, the target touches and is lifted up by the first locking member 102. The first locking member 102 rotates around the first supporting member 101 for a certain distance and then separates from the target and falls. After contacting the first limiting member 112, the first supporting member 101 and the first locking member 102 form a closed frame structure, and the target is in the closed frame structure. The first limiting member 112 can be a magnet.

The flexibility of setting the second locking member is improved to meet the locking requirements of angle irons of different sizes. The second locking member is a telescopic rod, which can be prismatic or cylindrical. The first connection end 130 of the second locking member needs to slide when mounted. Since the second connection end 131 is a rotating connection, the movement trajectory of the first connection end 130 is an arc. Therefore, it is necessary to set the slide rail to an arc slide rail, which makes the structure of the mounting component complicated. By using a telescopic rod as the second locking member 103, it is ensured that the slide rail is a linear guide rail, thereby reducing the structural complexity of the mounting component, facilitating manufacturing and saving costs.
