Description

Technical Field

[0001] The utility model relates to the technical field of electric power maintenance, in particular to an anti-falling device for electric power maintenance. Background Art

[0002] The process of power maintenance, since most of the time it is done at high altitude, requires a product that can store and protect power maintenance tools and prevent them from falling, so as to protect the lives of ground operators and ensure the smooth progress of the power maintenance process.

[0003] For example, the Chinese utility model patent with patent publication number CN217475926U includes an anti-fall frame, a mounting sleeve and a locking piece. The anti-fall frame is used to place power maintenance tools. The mounting sleeve is connected to the anti-fall frame and is used to install the anti-fall frame on the power pole; the locking piece is connected to the mounting sleeve to lock and fix the mounting sleeve and the power pole so that the mounting sleeve can be fixed on the power pole. This patent allows all kinds of power maintenance tools in the anti-fall frame to be fixed on the power pole, so that there is no need for workers to hold tools. At the same time, the anti-fall frame plays a role in storing and organizing the above-mentioned various power maintenance tools, reducing the probability of tools accidentally falling and injuring ground operators or damaging ground equipment, ensuring smooth maintenance while ensuring the safety of workers' operations. However, when construction is carried out at a distance from the top of the power pole, it is not convenient to lock the mounting sleeve on the power pole, which is inconvenient in actual operation. In view of this, we propose an anti-fall device for power maintenance. Utility Model Content

[0007] Preferably, a movement cavity is opened inside the U-shaped frame, the upper end of the bidirectional threaded rod rotates and penetrates into the movement cavity, and a locking disk is sleeved on the outer surface of the bidirectional threaded rod located inside the movement cavity.

[0008] Preferably, the top wall of the movement cavity is rotatably connected to a rotating disk, the lower surface of the rotating disk is fixedly connected to a spring, and the lower end of the spring is fixedly connected to a second locking disk.

[0009] Preferably, a protrusion is fixedly connected to a surface of one side of the locking disk close to the second locking disk, and a driving rod is fixedly connected to an upper surface of the second locking disk.

[0010] Preferably, the upper end of the driving rod movably passes through the upper surface of the U-shaped frame, the upper end of the driving rod is fixedly connected to a knob, and the left side surface of the first mounting plate is fixedly connected to a motor.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) When the anti-falling device for power maintenance needs to fix the anti-falling frame on the outer surface of the power pole, the arc groove on the first mounting plate is closely attached to the outer surface of the power pole, and then the second mounting plate is rotated so that the through groove on the locking claw is aligned with the locking column. At this time, the two locking plates are driven to move in opposite directions by the connecting component, so that the locking plate drives the locking column to enter the interior of the through groove to complete the locking. Through the above structure, when the anti-falling frame is fixed to the outer surface of the power pole, there is no need to insert the top end of the power pole. When working at a distance from the top end of the power pole, it can be fixed more conveniently.

[0015] (2) When the distance between the first mounting plate and the second mounting plate needs to be adjusted to accommodate power poles of different thicknesses, the anti-fall device for power maintenance can be driven by a motor to rotate the threaded rod. Since the U-shaped frame is limited in its movement trajectory by the cavity and the limit rod, the threaded rod will drive the U-shaped frame to move horizontally when it rotates, thereby adjusting the distance between the first mounting plate and the second mounting plate. Through the above structure, not only can the spring be used to prevent the anti-fall frame from loosening due to accidental contact with the knob, but the distance between the first mounting plate and the second mounting plate can also be adjusted to accommodate power poles of different thicknesses, thereby improving the scope of application of the anti-fall device.

At this time, the two locking plates 11 are driven to move in opposite directions by the connecting assembly, so that the locking plate 11 drives the locking column 12 to enter the inside of the through groove 9 to complete the locking. Through the above structure, when the anti-fall frame 1 is fixed on the outer surface of the power pole, there is no need to insert the top end of the power pole, and it can be fixed more conveniently when working at a distance from the top end of the power pole.

[0024] Furthermore, the connecting assembly includes two mounting ears 13, and the two mounting ears 13 are fixedly connected to the right side surface of the U-shaped frame 5. The upper side surfaces of the two mounting ears 13 are provided with locking grooves 14 extending from the lower side surfaces thereof. The bottom wall of the sliding groove 10 is rotatably connected with a bidirectional threaded rod 15, and the two locking plates 11 are respectively threadedly sleeved on two opposite threads of the bidirectional threaded rod 15. A movement cavity 16 is provided inside the U-shaped frame 5, and the upper end of the bidirectional threaded rod 15 is rotatably penetrated into the interior of the movement cavity 16. The outer surface of the bidirectional threaded rod 15 located inside the movement cavity 16 is sleeved with a locking disk 17, and the top wall of the movement cavity 16 is rotatably connected with a rotating disk 18, and the lower side surface of the rotating disk 18 is fixedly connected There is a spring 19, the lower end of the spring 19 is fixedly connected to a second locking disk 20, the side surfaces of the locking disk 17 close to the second locking disk 20 are respectively fixedly connected with protrusions 21, the upper surface of the second locking disk 20 is fixedly connected to a driving rod 22, the upper end of the driving rod 22 movably penetrates the upper surface of the U-shaped frame 5, the upper end of the driving rod 22 is fixedly connected to a knob 23, the left side surface of the first mounting plate 2 is fixedly connected to a motor 24, the output end of the motor 24 is fixedly connected to a threaded rod 25, the right end of the threaded rod 25 rotates and penetrates into the interior of the cavity 4, the U-shaped frame 5 is threadedly sleeved on the outer surface of the threaded rod 25, the left and right inner walls of the cavity 4 are fixedly connected to limit rods 26, the U-shaped frame 5 The sliding sleeve is arranged on the outer surface of the limit rod 26. By pressing the knob 23 downward, the knob 23 is used to drive the driving rod 22 and the second locking plate 20 to descend. When the second locking plate 20 descends, the spring 19 will be stretched. At the same time, after the second locking plate 20 descends, it will be tightly attached to the locking plate 17. With the help of the protrusion 21, the second locking plate 20 is engaged with the locking plate 17. At this time, turning the knob 23 can drive the locking plate 17 to rotate. When the locking plate 17 rotates, it will synchronously drive the bidirectional threaded rod 15 to rotate. Since the locking plate 11 is restricted in its movement trajectory by the sliding groove 10, when the bidirectional threaded rod 15 rotates, it will synchronously drive the locking plate 11 to move. After the locking is completed, release the knob 23, and the spring 19 can be used to release the locking plate 11. The locking plate 17 is separated from the second locking plate 20. When the distance between the first mounting plate 2 and the second mounting plate 6 needs to be adjusted to adapt to power poles of different thicknesses, the threaded rod 25 can be driven to rotate by the motor 24. Since the U-shaped frame 5 is restricted in its movement trajectory by the cavity 4 and the limit rod 26, the U-shaped frame 5 will be driven to move horizontally when the threaded rod 25 rotates, thereby adjusting the distance between the first mounting plate 2 and the second mounting plate 6. Through the above structure, not only can the spring 19 be used to prevent the anti-fall frame 1 from loosening due to accidental contact with the knob 23, but the distance between the first mounting plate 2 and the second mounting plate 6 can also be adjusted to adapt to power poles of different thicknesses, thereby improving the scope of application of the anti-fall device.

[0025] Working principle: When it is necessary to fix the anti-fall frame 1 on the outer surface of the power pole, the arc groove 3 on the first mounting plate 2 is closely attached to the outer surface of the power pole, and then the second mounting plate 6 is rotated to align the through groove 9 on the locking claw 8 with the locking column 12.

By pressing the knob 23 downward, the knob 23 is used to drive the driving rod 22 and the second locking plate 20 to descend. When the second locking plate 20 descends, the spring 19 will be stretched. At the same time, after the second locking plate 20 descends, it will be closely attached to the locking plate 17. With the help of the protrusion 21, the second locking plate 20 is engaged with the locking plate 17. At this time, the knob 2 is turned. 3 can drive the locking plate 17 to rotate, and when the locking plate 17 rotates, it will synchronously drive the bidirectional threaded rod 15 to rotate.

After the locking is completed, the knob 23 is released, and the locking plate 17 and the second locking plate 20 can be separated with the help of the spring 19. When it is necessary to adjust the distance between the first mounting plate 2 and the second mounting plate 6 to adapt to power poles of different thicknesses, the threaded rod 25 can be driven to rotate by the motor 24. Since the movement trajectory of the U-shaped frame 5 is limited by the cavity 4 and the limit rod 26, when the threaded rod 25 rotates, it will drive the U-shaped frame 5 to move horizontally, thereby adjusting the distance between the first mounting plate 2 and the second mounting plate 6.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
