[0002] Climbing utility poles to perform power maintenance work is a dangerous task that requires professional skills and strict safety measures.

[0012] In the above technical solution, further, a gripping portion is fixedly connected between the clamping assembly and the adjusting assembly.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By rotating the adjustment rod, the two clamping assemblies move toward each other, so that the electric pole can be clamped, and the connection belt is connected to the safety belt worn by the maintenance personnel. The clamping assembly and the connecting plate are connected only by the connecting arm to form a semicircular structure, so obstacles such as brackets can be avoided, allowing maintenance personnel to climb higher, solving the problem in the prior art that maintenance personnel are blocked by obstacles such as bracket clamps and cannot climb higher while the elastic rope is set on the electric pole;

[0015] The pulley can be clamped against the outer wall of the pole, so that the connecting belt can firmly bear the weight of the maintenance personnel. At the same time, the pulley can rotate along the outer wall of the pole, so that it can smoothly move up and down on the pole, which is more convenient for the maintenance personnel to climb up and down. Through the mutual contact and collision of the first elastic block and the second elastic block, a certain force is required to drive the pulley to rotate, so that the first elastic block and the second elastic block are squeezed and deformed against each other, so that the pulley can be ensured to have a certain self-locking property and can provide a certain self-locking force to limit the rotation of the pulley, so that it is convenient for the maintenance personnel to free up their hands to carry out related maintenance operations.

[0016] When the pulley encounters a hoop, a bracket or a plant wrapped around a pole, the lateral rebound provided by the insertion rod and the return spring can make the pulley retract into the inside of the shell at different amplitudes, thereby ensuring that the device can adaptively adapt to the obstruction of some obstacles and roll along its surface without the maintenance personnel having to manually adjust the adjustment rod;

[0017] After the sensor detects that an object has touched the electromagnet, the electromagnet is energized and its axis generates magnetic force and attracts the magnetic block to contact the axis on the electromagnet, thereby locking the rotation of the rotating sleeve, and correspondingly preventing the pulley from rotating, so that the pulley will not rotate rapidly along the pole due to the force of the human body falling. This design enhances the friction between the device and the pole after locking the pulley, thereby preventing the device from falling rapidly due to the weight of the person, and providing a pulling force to prevent the maintainer from falling to the ground;

[0018] The de-energized electromagnet loses its magnetism after being energized, allowing the movable plate to move. The electric push rod is energized and drives the driving rod to push the pulley outward, thereby making the pulley close to the pole, further increasing the friction force in a short time, so that the device can be more firmly fixed on the pole, providing a stronger pulling force to prevent maintenance personnel from falling to the ground.

Therefore, the directional words used are used to illustrate rather than limit the invention.

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] A device for preventing electric tools from falling when used for high-altitude electric maintenance, such as Figure 1-Figure 7 As shown, it includes a pair of clamping components 2, an adjusting component 1 is arranged between the pair of clamping components 2, the adjusting component 1 includes a connecting arm 9 fixedly connected to one side of the clamping component 2, a connecting block 6 is fixedly connected to one side of the outer wall of the connecting arm 9, a slider 4 is fixedly connected to one side of the outer wall of the connecting block 6, a connecting plate 3 is slidably connected to the outer wall of the slider 4, the same adjusting rod 5 is inserted and screwed between the two sliders 4, a connecting belt 7 is arranged inside the connecting block 6, and the other end of the connecting belt 7 is connected to an external safety belt, the two clamping components 2 are moved towards each other by rotating the adjusting rod 5, and the electric pole can be clamped, and the connecting belt 7 is connected to the safety belt worn by the maintenance personnel, the clamping component 2 and the connecting plate 3 are connected only by the connecting arm 9 to form a semicircular structure, so obstacles such as brackets can be avoided, allowing maintenance personnel to climb higher, solving the problem in the prior art that maintenance personnel are blocked by obstacles such as bracket clamps and cannot ensure climbing higher while the elastic rope is set on the electric pole.

[0030] like Figure 2 As shown, the clamping assembly 2 includes a housing 10 fixedly connected to one side of the outer wall of the connecting arm 9, a clamping plate 17 is inserted and slidably connected inside the housing 10, a pulley frame 15 is fixedly connected to one side of the clamping plate 17, a pulley 16 is arranged inside the pulley frame 15, and an insertion shaft 27 is fixedly connected to one side of the inner wall of the pulley frame 15, as shown in FIG. Figure 4 As shown, one end of the outer wall of the plug shaft 27 is fixedly connected with a uniformly distributed second elastic block 28, and a rotating sleeve 25 is inserted and fixedly connected inside the pulley 16, and the plug shaft 27 is inserted into the inside of the rotating sleeve 25, and the inner edge of one end of the rotating sleeve 25 is fixedly connected with a uniformly distributed first elastic block 26, and the first elastic block 26 and the second elastic block 28 are adapted to each other, and the pulley 16 can fit the outer wall of the pole for clamping, so that the connecting belt 7 can firmly bear the weight of the maintenance personnel. At the same time, the pulley 16 can rotate along the outer wall of the pole, so that it can smoothly move up and down on the pole, which is more convenient for the maintenance personnel to climb up and down. Through the mutual contact and collision of the first elastic block 26 and the second elastic block 28, a certain force is required to drive the pulley 16 to rotate, so that the first elastic block 26 and the second elastic block 28 are squeezed and deformed against each other, so as to ensure that the pulley 16 has a certain self-locking property and can provide a certain self-locking force to limit the rotation of the pulley 16, so as to facilitate the maintenance personnel to free their hands to carry out related maintenance operations.

[0031] A fixed frame 11 is fixedly connected to the inner wall of the shell 10, and a movable plate 12 is arranged on one side of the fixed frame 11. A power-off type electromagnet 18 is fixedly installed on one side of the outer wall of the fixed frame 11, and the power-off type electromagnet 18 and the movable plate 12 are magnetically matched. A pair of plug rods 13 are fixedly connected to one side of the movable plate 12, and the plug rods 13 are inserted and slidably connected to one side of the outer wall of the clamp 17. A return spring 14 is sleeved on the outer wall of the plug rod 13. When the pulley 16 encounters a hoop, a bracket or a plant wrapped around a telephone pole, the lateral rebound provided by the plug rod 13 and the return spring 14 can make the pulley 16 retract to the inside of the shell 10 with different amplitudes, thereby ensuring that the maintenance personnel can adaptively adapt to the obstruction of some obstacles and roll along its surface without manually adjusting the adjusting rod 5.

[0032] like Figure 6 and Figure 7 As shown, the connecting block 6 includes an inner frame 32 and an outer frame 34 connected to each other, the inner frame 32 is fixedly connected to one side of the outer wall of the connecting block 6, and the outer frame 34 is fixedly connected to one side of the outer wall of the inner frame 32, a first winding shaft 33 is inserted and rotatably connected inside the inner frame 32, and the connecting belt 7 is wound around the shaft of the first winding shaft 33, both sides of the inner wall of the outer frame 34 are fixedly connected with fixing plates 37, a second winding shaft 35 is inserted and rotatably connected between the two fixing plates 37, a slide plate 38 is slidably connected to the outer wall of the fixing plate 37, a protruding column 40 is fixedly connected to the top of the slide plate 38, a pair of pressing blocks 39 are fixedly connected to the bottom of the slide plate 38, a sensor 36 is fixedly installed at the bottom of the inner wall of the outer frame 34, a first elastic plate 41 is fixedly connected to the bottom of the inner wall of the outer frame 34 through a vertical plate, and a first elastic plate 41 is fixedly connected to the outer wall of the first elastic plate 41 A second elastic plate 42 is connected, and a third elastic plate 43 is fixedly connected to one side of the inner wall of the outer frame 34. When the maintenance personnel are in normal operation or climbing work, the connecting belt 7 forms a certain angle with the maintenance personnel. At this angle, the connecting belt 7 will not touch the protruding column 40. When the maintenance personnel falls rapidly, the angle is broken, and the connecting belt 7 will quickly flip downward along the second winding axis 35, contact the protruding column 40 and drive it to move downward, so that the pressure block 39 breaks through the constraint formed by the first elastic plate 41 and the third elastic plate 43 and forces it to deform. When the second elastic plate 42 is deformed to a certain extent, it contacts the sensor 36. At this time, the sensor 36 can detect that the maintenance personnel is in a falling state. An electromagnet 44 is fixedly installed on the other side of the outer wall of the pulley frame 15, and the shaft of the electromagnet 44 is inserted into the inside of the rotating sleeve 25. Figure 5As shown, the other end of the inner wall of the rotating sleeve 25 is provided with evenly distributed mounting grooves 29, and the interior of the mounting grooves 29 is fixedly connected with evenly distributed spring pieces 30, and the ends of the spring pieces 30 are fixedly connected with magnetic matching blocks 31, which are inserted and slidably connected to the interior of the mounting grooves 29, and the magnetic matching blocks 31 are magnetically matched with the electromagnet 44. After the sensor 36 detects that an object is in contact, the electromagnet 44 is energized and its axis generates magnetic force and attracts the magnetic matching block 31 to contact the axis on the electromagnet 44, thereby locking the rotation of the rotating sleeve 25, and correspondingly making the pulley 16 no longer rotate, so that the pulley 16 will not rotate rapidly along the electric pole due to the force of the human body falling. This design enhances the friction between the device and the electric pole after locking the pulley 16, thereby preventing the device from falling rapidly due to the weight of the person, and providing a pulling force to prevent the maintainer from falling to the ground.

[0033] A pair of first slide rails 20 and second slide rails 21 are fixedly connected to the inner wall of the shell 10, and the clamping plate 17 and the movable plate 12 are slidably connected to the outer walls of the first slide rails 20 and the second slide rails 21 respectively. An electric push rod 19 is fixedly installed on the inner wall of the fixed frame 11, and the driving rod of the electric push rod 19 is connected to the movable plate 12. After the sensor 36 detects that an object is in contact, the de-energized electromagnet 18 loses magnetism after being energized, so that the movable plate 12 can move. The electric push rod 19 is energized and drives the driving rod to push the pulley 16 outward, thereby making the pulley 16 close to the electric pole, further improving the friction force in a short time, so that the device can be more firmly fixed on the electric pole, providing a stronger pulling force to prevent maintenance personnel from falling to the ground.

[0034] like Figure 3 As shown, a pair of corresponding first rotating members 22 are fixedly installed on the side where the movable plate 12 and the clamping plate 17 are close to each other, and a connecting plate 24 is rotatably connected to one side of the outer wall of the first rotating member 22, and a second rotating member 23 is rotatably connected between two adjacent connecting plates 24. After being squeezed, the clamping plate 17 approaches the movable plate 12. This design can ensure that the movement can be maintained straight during the process to avoid uneven force or deviation in the moving direction.

[0035] A gripping portion 8 is fixedly connected between the clamping assembly 2 and the adjusting assembly 1. This design can facilitate maintenance personnel to move the device up and down.

[0036] Working principle:

[0037] By rotating the adjusting rod 5, the two clamping assemblies 2 move toward each other, so that the electric pole can be clamped, and the connection belt 7 is connected to the safety belt worn by the maintenance personnel. The clamping assembly 2 and the connecting plate 3 are connected only by the connecting arm 9 to form a semicircular structure, so obstacles such as brackets can be avoided, allowing the maintenance personnel to climb higher, solving the problem in the prior art that the maintenance personnel are blocked by obstacles such as bracket clamps and cannot climb higher while the elastic rope is set on the electric pole;

[0038] The pulley 16 can be clamped against the outer wall of the pole, so that the connecting belt 7 can firmly bear the weight of the maintenance personnel. At the same time, the pulley 16 can rotate along the outer wall of the pole, so that it can smoothly move up and down on the pole, which is more convenient for the maintenance personnel to climb up and down. Through the mutual contact and collision of the first elastic block 26 and the second elastic block 28, a certain force is required to drive the pulley 16 to rotate, so that the first elastic block 26 and the second elastic block 28 are squeezed and deformed against each other, so that the pulley 16 can be ensured to have a certain self-locking property and can provide a certain self-locking force to limit the rotation of the pulley 16, so that it is convenient for the maintenance personnel to free up their hands to carry out related maintenance operations.

[0039] When the pulley 16 encounters a hoop, a bracket or a plant wrapped around a pole, the lateral rebound provided by the insertion rod 13 and the return spring 14 can make the pulley 16 retract into the inside of the housing 10 at different amplitudes, thereby ensuring that the maintenance personnel can adaptively adapt to the obstruction of some obstacles and roll along the surface without manually adjusting the adjustment rod 5;

[0040] After the sensor 36 detects that an object has contacted, the electromagnet 44 is energized and its axis generates magnetic force and attracts the magnetic block 31 to contact the axis on the electromagnet 44, thereby locking the rotation of the rotating sleeve 25, and correspondingly making the pulley 16 no longer rotate, so that the pulley 16 will not rotate rapidly along the pole due to the force of the human body falling. This design enhances the friction between the device and the pole after locking the pulley 16, thereby preventing the device from falling rapidly due to the weight of the person, and providing a pulling force to prevent the maintenance person from falling to the ground;

[0041] After the de-energized electromagnet 18 is energized, it loses its magnetism, allowing the movable plate 12 to move. The electric push rod 19 is energized and drives the driving rod to push the pulley 16 outward, thereby making the pulley 16 close to the pole, further increasing the friction force in a short time, so that the device can be more firmly fixed on the pole, providing a stronger pulling force to prevent the maintenance personnel from falling to the ground.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
