Description

Technical Field

[0001] The present invention belongs to the technical field of anti-falling devices, and particularly relates to an anti-falling device for climbing a transmission tower. Background Art

[0002] With the rapid development of overhead power lines, the line voltage level and the height of transmission towers have been continuously increasing. At present, manual tower climbing inspection is still the main method for overhead line maintenance. As a high-altitude dangerous operation type, manual tower climbing inspection consumes a large amount of physical strength of personnel and is prone to dangerous events such as personnel falling from high altitudes. Therefore, preventing high-altitude falling accidents has become the primary problem for line safety operations.

[0003] Traditional anti-falling devices are usually built together with the construction of transmission towers and cannot be separated from the transmission towers after construction, which undoubtedly increases the construction cost of the transmission towers. Moreover, the anti-falling devices added later to the towers still need to be installed manually without protection measures, and cannot play the role of preventing falls. Due to the wide application of drones at present, using drones to quickly install anti-falling devices for climbing towers has become a feasible installation method. However, there is a lack of anti-falling devices for climbing towers on the market that can be installed and disassembled by drones. Based on this, we propose an anti-falling device for climbing a transmission tower to solve the above problems. Summary of the Invention

Specific embodiments

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] Embodiment 1:

[0053] Referring to Figures 1 to 7 , the present invention discloses an anti-falling device for climbing a transmission tower, including:

[0054] Frame body;

[0055] The UAV hook plate 3 is installed at the top of the frame body, and the UAV hook plate 3 is used to connect with the UAV;

[0056] The safety rope lock sleeve 9 is fixedly connected to one side of the frame body and is used to fixedly connect with one end of the safety rope;

[0057] A self-locking structure is installed at the bottom of the frame body. The self-locking structure is set to be able to be opened and locked. When the self-locking structure is opened, it is used for the UAV to place the frame body on the cross bar of the tower. When the self-locking structure is locked, the self-locking structure and the frame body are cooperatively sleeved outside the cross bar of the tower;

[0058] The crossbar adaptive structure is installed on the inner side of the top of the frame, and the crossbar adaptive structure is configured to be adaptively changed according to the crossbar structure of the iron tower.

[0059] When in use, a hook is installed at the bottom of the drone, so that the hook is hooked on the drone hook plate 3, and the drone hook plate 3 carries the device as a whole and lifts it to the high point of the transmission tower, and then descends to the crossbeam at the appropriate position of the transmission tower. At this time, the self-locking structure is opened, so that the crossbeam enters the frame through the self-locking structure. As the drone carrying device continues to descend, the crossbar adaptive structure contacts the tower crossbar. The crossbar adaptive structure changes adaptively according to the structure of the tower crossbar, so that the device as a whole can be stably fixed on the tower crossbar. Then the self-locking structure is closed, and the tower crossbar is sleeved in the space formed by the frame and the self-locking structure. At this time, the self-locking structure is locked, and the device is sleeved on the outside of the tower crossbar to prevent it from falling off the tower crossbar. The safety rope is sleeved in the safety rope lock sleeve 9 in advance. At this time, one end of the safety rope is connected to the transmission tower. After the construction personnel install the speed difference anti-fall device on the safety rope, they can carry out climbing operations. The present invention facilitates connection with a drone through the setting of a drone hook plate 3, and realizes installation on a transmission tower through the cooperation of a self-locking structure and a frame. The device is easy to combine with a transmission tower, and no climbing operation is required when hanging a safety rope, thereby ensuring the safety of operators.

[0060] As an optional implementation, the frame includes:

[0061] Two upright posts 2, the two upright posts 2 are fixed by a crossbeam 1, and a safety rope lock sleeve 9 is fixedly connected to the outer side wall of one of the upright posts 2;

[0062] A sliding column 6 is slidably arranged in the column 2, and the column 2 and the sliding column 6 are limitedly matched;

[0063] The platform 5 is fixed to the top of the two sliding columns 6, and the top of the platform 5 is fixed to the bottom of the drone hook plate 3 through the connecting frame 4;

[0064] The crossbar adaptive structure is installed on the crossbeam 1;

[0065] The self-locking structure is arranged between the two upright posts 2 , and one of the sliding posts 6 is drivingly connected to the self-locking structure.

[0066] As an optional implementation, a limiting plate 12 is fixedly connected inside the column 2 , the limiting plate 12 is limitedly matched with a limiting plate 2 13 , and the limiting plate 2 13 is fixedly connected to the sliding column 6 .

[0067] The first limiting plate 12 and the second limiting plate 13 are used to prevent the upright column 2 and the sliding column 6 from slipping off.

[0068] Furthermore, during the takeoff process of the drone, since the safety rope lock sleeve 9 is connected to the safety rope, the device may tilt. By selecting columns 2 with different lengths, the length of the column 2 without the safety rope lock sleeve 9 is made longer than that of the column 2 with the safety rope lock sleeve 9, and the fixed position of the drone hook plate 3 and the platform 5 is adjusted. By setting like this, the center of gravity of the device is offset, so that the device will not tilt after the drone carries the device into the air, which is convenient for sleeving the frame on the cross bar of the iron tower.

[0069] As an alternative embodiment, the cross bar self - adapting structure includes a plurality of sliding diaphragms 7 arranged side by side; there are two cross beams 1, which are respectively fixedly connected to the front and rear sides of the column 2. A plurality of sliding diaphragms 7 are slidably arranged between the two cross beams 1, and the cross beam 1 is in limit fit with the top of the sliding diaphragm 7.

[0070] As an alternative embodiment, the sliding diaphragm 7 includes a diaphragm 701. Limit blocks 702 are respectively fixedly connected to the front and rear sides of the top and bottom of the diaphragm 701, and the limit blocks 702 are in limit fit with the cross beam 1.

[0071] When the device takes off, a plurality of sliding diaphragms 7 slide down naturally under the action of gravity, and the bottom of the limit block 702 is in limit fit with the top of the cross beam 1. When the device descends and contacts the cross bar of the iron tower, the bottom of the diaphragm 701 in contact with the cross bar of the iron tower is jacked up, and the positions of the remaining diaphragms 701 remain unchanged. The top of the limit block 702 at the bottom of the jacked - up diaphragm 701 is in limit fit with the bottom of the cross beam 1, so that the device can be stably placed on the cross bar of the iron tower as a whole.

[0072] Through the above settings, the device can adapt to various shapes of tower materials such as "L", "Г", "T", "⊥", etc., and has strong adaptability.

[0073] As an alternative embodiment, the safety rope lock sleeve 9 includes:

[0074] Two lock sleeves 901, with a gap between the two lock sleeves 901. A connecting plate 902 is arranged between the two lock sleeves 901, and the two ends of the connecting plate 902 are respectively fixedly connected to the lock sleeves 901. The lock sleeve 901 is fixed to the outer wall of the corresponding column 2 through a fixing plate 10;

[0075] An opening is provided in the middle of the lock sleeve 901, and the opening is located between the connecting plate 902 and the fixing plate 10;

[0076] The opening communicates with a relief groove 17, and the relief groove 17 is opened at the bottom of the corresponding column 2.

[0077] After the safety rope is wound into a rope sleeve, it can pass through the relief groove 17 and the opening in the middle of the lock sleeve 901 in sequence and enter into the two lock sleeves 901.

[0078] As an alternative embodiment, the self - locking structure includes:

[0079] The articulated rod 8 has one end articulated to one of the columns 2, and the other end of the articulated rod 8 is suspended and is in limiting cooperation with a plug 16. The plug 16 is horizontally slidably arranged on the other column 2;

[0080] The first spring 11 has its lower end fixedly connected to the center of the top of the articulated rod 8, and the upper end of the first spring 11 is fixedly connected to the column 2 away from the plug 16.

[0081] As an alternative embodiment, the plug 16 includes:

[0082] A plug body 1601, one end of the plug body 1601 is provided with a slope, and the other end of the plug body 1601 is fixedly connected with a plug head 1603. The plug head 1603 extends into the articulated rod 8 and is in limiting cooperation with it;

[0083] The second spring 1604 is sleeved outside the plug body 1601. One end of the second spring 1604 is fixedly connected to the outer wall of the corresponding column 2, and the other end of the second spring 1604 is fixedly connected to the plug head 1603;

[0084] The third limiting plate 1602 is fixedly connected to the end of the plug body 1601 away from the plug head 1603 and is located inside the corresponding column 2. The third limiting plate 1602 is in limiting cooperation with the inner wall of the corresponding column 2;

[0085] The plug body 1601 is in driving connection with the bottom end of the corresponding sliding column 6;

[0086] After the sliding column 6 descends, it contacts the slope of the plug body 1601 and pushes the plug body 1601 to make the plug head 1603 enter the articulated rod 8 and stretch the second spring 1604.

[0087] As an alternative embodiment, the articulated rod 8 includes a rod body 801. One end of the rod body 801 is provided with a flared limiting groove 802 for limiting cooperation with the plug head 1603. The other end of the rod body 801 is articulated to the corresponding column 2 through an articulated seat 803;

[0088] The middle of the rod body 801 is fixedly connected to the lower end of the first spring 11.

[0089] During use, when the drone hooks the drone hook plate 3 and takes off, it will pull the sliding column 6 to move upward relative to the column 2, and drive the whole device to rise under the limiting cooperation of the first limiting plate 12 and the second limiting plate 13. At this time, the end of the articulated rod 8 is in a movable state. When the device is placed on the crossbar of the iron tower, the articulated rod 8 contacts the crossbar of the iron tower and is lifted, and then automatically resets to the horizontal after passing through the crossbar of the iron tower. The setting of the first spring 11 is used to overcome the gravity of the articulated rod 8 so that the articulated rod 8 can maintain a horizontal state;

[0090] Furthermore, a torsion spring is provided between the rod body 801 and the hinge seat 803 for making the rod body 801 horizontal.

[0091] Furthermore, the high end of another first spring 11 is fixedly connected to the center of the bottom of the rod body 801, and the low end of the another first spring 11 is fixedly connected to the column 2 away from the plug 16.

[0092] When the device is gradually lowered, each sliding diaphragm 7 is displaced under the action of the cross bar of the iron tower, so that the device stays stably on the cross bar of the iron tower. As the UAV continues to lower, the sliding column 6 moves downward relative to the column 2 under the action of gravity. At this time, the bottom end of the sliding column 6 descends and contacts the slope of the plug body 1601, and pushes the plug body 1601 to make the plug head 1603 enter the flared limiting groove 802 and stretch the second spring 1604. The purpose of setting the flared limiting groove 802 in a flared shape is to facilitate the entry of the plug head 1603.

[0093] As the sliding column 6 moves downward in place, at this time, the plug body 1601 and the sliding column 6 are in limit cooperation to lock the rod body 801 and prevent it from rotating. At the same time, the sliding column 6 blocks the middle opening of the lock sleeve 901 to prevent the safety rope sleeve from falling off.

[0094] When removing this device, the UAV lifts the UAV hook plate 3, so that the sliding column 6 moves upward. The sliding column 6 and the plug body 1601 are released from the limit state. The second spring 1604 contracts to move the plug head 1603 out of the flared limiting groove 802, and the rod body 801 can rotate freely to be separated from the cross bar of the iron tower.

[0095] As an optional implementation manner, the UAV hook plate 3 includes a frame 301, and a wavy hook groove 302 is arranged inside the top of the frame 301. The wavy hook groove 302 is used for hooking with the UAV.

[0096] The wavy hook groove 302 is designed in a non-slip serrated shape to prevent the main body of the device from sliding frequently during the UAV hooking.

[0097] Embodiment 2:

[0098] Reference Figures 8 to 9, the difference between this embodiment and Embodiment 1 is that a counterweight box 22 is fixedly connected to the bottom end of one of the columns 2. The counterweight box 22 is filled with a damping fluid. A piston assembly 23 is slidably connected in the counterweight box 22. The top end of the piston assembly 23 is fixedly connected to the bottom end of the corresponding sliding column 6 through a connecting steel pipe 24. The piston assembly 23 includes a piston 2301 and communication holes 2302 circumferentially and equally spaced on the piston 2301. The communication holes 2302 are vertically penetrated. The top of the piston 2301 is axially connected to the bottom of the connecting steel pipe 24. The communication holes 2302 are detachably connected with plugs 27. A plurality of plugs 27 are fixedly connected to the bottom of the sliding plate 26. The sliding plate 26 is vertically slidably connected to the bottom of the connecting steel pipe 24 through a sliding groove 25. When the sliding plate 26 slides, the plugs 27 enter or are pulled out of the corresponding communication holes 2302. The top end of the reinforcing bar 21 is fixedly connected to the bottom of the sliding plate 26. The top end of the reinforcing bar 21 penetrates through the connecting steel pipe 24 and the corresponding sliding column 6 and is fixedly connected with a lifting plate 18. The lifting plate 18 is slidably connected to the top of the platform 5 through a guiding block 20. The lifting plate 18 is fixedly connected to the connecting frame 4. The lifting plate 18 is magnetically connected with a magnetic attraction block 19. The magnetic attraction block 19 is embedded and fixed on the top of the platform 5.

[0099] To prevent the device from accidentally falling off the crossbar of the iron tower, at this time, to ensure safety, the sleeved state of the device and the crossbar of the iron tower should be ensured, and the locking of the hinge rod 8 should be ensured.

[0100] Its working principle is that a vertically slidable lifting plate 18 is arranged on the platform 5. The lifting plate 18 and the platform 5 are magnetically attracted and matched through the magnetic attraction block 19. When the drone lifts the device, under the action of the overall gravity of the device, the lifting plate 18 is separated from the platform 5. The bottom of the lifting plate 18 is fixedly connected with a guiding block 20. The guiding block 20 is slidably connected to the platform 5. The bottom of the guiding block 20 is in limit cooperation with the bottom of the platform 5. At this time, the lifting plate 18 will also drive the sliding column 6 to rise. The sliding column 6 is connected to the sliding plate 26. The sliding plate 26 slides upward in the sliding groove 25 to separate the plug 27 from the communication hole 2302. The counterweight box 22 is filled with a damping liquid (such as water, oil). At this time, the communication hole 2302 is penetrated, so that the piston 2301 can slide vertically in the counterweight box 22. As the drone releases the device, the sliding column 6 slowly moves downward under the action of gravity and drives the piston 2301 to move downward through the connecting steel pipe 24. After the sliding column 6 stops moving, the lifting plate 18 continues to move downward until it is magnetically adsorbed to the magnetic attraction block 19. The reinforcing bar 21 pushes the sliding plate 26 downward to block the communication hole 2302 with the plug 27.

[0101] When the device accidentally tilts and falls off, even if the device is turned over, since the gravity of the lifting plate 18 is not enough to overcome the suction force of the magnetic attraction block 19, it cannot fall off. At this time, it can be ensured that the communication hole 2302 is blocked by the plug 27. Under the action of the damping fluid, the piston 2301 cannot move. Therefore, it can be ensured that the column 2 and the sliding column 6 do not displace, and further ensure the locking of the hinge rod 8 and the blocking of the opening of the safety rope sleeve 9.

[0102] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
