The speed limiting unit 4 includes a rotating disk 41, a first positioning member 42 and a second positioning member 43. The rotating disk 41 is coaxially connected to the storage roller 22. The first positioning member 42 and the second positioning member 43 can approach each other and clamp the rotating disk 41 or move away from each other and release the rotating disk 41.

[0049] In short, the emergency landing device for the power grid tower provided by the present invention installs the housing 21 of the lifting unit 2 on the fixing plate 11 of the fixing unit 1, and the fixing plate 11 can be installed at the corresponding height position of the power grid tower. One end of the pulling rope 23 is connected to the storage roller 22 inside the housing 21, and the other end of the pulling rope 23 is connected to the safety belt 3. The operator can be tied to the emergency landing device for the power grid tower through the safety belt 3. The operator can be lowered by rotating the storage roller 22, without manual climbing, and can assist personnel to automatically land from the power grid tower, thereby improving the safety and convenience of power grid tower maintenance. The rotating disk 41 of the speed limiting unit 4 is coaxially connected to the storage roller 22. Through the cooperation of the first positioning member 42 and the second positioning member 43, the rotation speed of the storage roller 22 can be limited, providing the operator with a suitable descent speed and improving the comfort of use.

[0050] Furthermore, if Figure 2 Combination Figure 3 As shown, the lifting unit 2 also includes a first mounting plate 24 and a second mounting plate 25, the first mounting plate 24 is arranged above the side wall of the housing 21, a first shaft 241 is arranged on the first mounting plate 24, the second mounting plate 25 is arranged below the side wall of the housing 21, and a second shaft 251 and a third shaft 252 are arranged on the second mounting plate 25 at intervals, and the emergency landing device for the power grid tower also includes an adjustment unit 5, the adjustment unit 5 includes a rotating rod 51, a first connecting rod 52, a power rod 53, a second connecting rod 54 and a toggle rod 55, and the first end of the rotating rod 51 rotates with the first shaft 241 The second end of the rotating rod 51 is hinged to the upper end of the first connecting rod 52, the power rod 53 is rotatably set on the second shaft 251, the first end of the power rod 53 is hinged to the lower end of the first connecting rod 52, the second end of the power rod 53 is hinged to the lower end of the second connecting rod 54, the first end of the toggle rod 55 is hinged to the upper end of the second connecting rod 54, and the second end of the toggle rod 55 is rotatably connected to the third shaft 252; the first positioning member 42 is set on the rotating rod 51, the second positioning member 43 is set on the toggle rod 55, and the rotating disk 41 is located between the first positioning member 42 and the second positioning member 43. When the adjustment unit 5 is in the initial state, the rotating rod 51, the power rod 53 and the toggle rod 55 are parallel to each other and are in a horizontal state. Figure 3 For example, when the power rod 53 is rotated counterclockwise, the first positioning member 42 on the rotating rod 51 and the second positioning member 43 on the toggle rod 55 can be moved closer to the rotating disk 41. When the power rod 53 is rotated clockwise, the first positioning member 42 on the rotating rod 51 and the second positioning member 43 on the toggle rod 55 can be moved away from the rotating disk 41.

[0051] Furthermore, a third mounting plate 26 is provided on the side wall of the housing 21, and the adjustment unit 5 further includes a linear drive module 56, a fixed end of the linear drive module 56 is connected to the third mounting plate 26, and a telescopic end of the linear drive module 56 is hinged to the first end of the power rod 53. When the telescopic end of the linear drive module 56 presses down the first end of the power rod 53, the second end of the power rod 53 can be moved upward, thereby increasing the clamping force of the first positioning member 42 and the second positioning member 43 on the rotating disk 41; when the telescopic end of the linear drive module 56 pulls up the first end of the power rod 53, the second end of the power rod 53 can be moved downward, thereby reducing the clamping force of the first positioning member 42 and the second positioning member 43 on the rotating disk 41.

[0052] Exemplarily, the linear drive module 56 may be, but is not limited to, a hydraulic rod or an electric push rod, and no further limitation is given herein.

[0053] Furthermore, the lifting unit 2 further includes a rotation drive module 27, which is disposed on the housing 21 and is in transmission connection with the storage roller 22. The rotation drive module 27 can drive the storage roller 22 to rotate, thereby providing tension to the safety belt 3 through the pulling rope 23. Optionally, the pulling rope 23 can be, but is not limited to, a steel wire rope or a nylon rope.

[0054] Exemplarily, the rotation drive module 27 includes a motor or a driving gear. In this embodiment, a motor is used to directly drive the storage roller 22 to rotate. In other embodiments, a driven gear is fixedly sleeved on one end of the storage roller 22, and the storage roller 22 can also be driven by meshing the driving gear with the driven gear.

[0055] Furthermore, if Figure 2 As shown, the safety belt 3 includes a backrest pad 31, two first straps 32 and two second straps 33. The two first straps 32 are both arranged at the top of the backrest pad 31, and one end of the pulling rope 23 is connected to the top of the backrest pad 31 and is located between the two first straps 32. The two second straps 33 are respectively arranged on both sides of the backrest pad 31, and the first straps 32 and the second straps 33 are clamped. The first strap 32 and the second strap 33 located on the left side are used to fix the left shoulder of the human body, and the first strap 32 and the second strap 33 located on the right side are used to fix the right shoulder of the human body, so as to improve the binding stability between the human body and the safety belt 3 and prevent the operator from being separated from the safety belt 3 during the operation and causing danger.

[0056] Specifically, a first locking member 321 is provided at the end of the first strap 32, and a second locking member 331 is provided at the end of the second strap 33. The first locking member 321 can be engaged with the second locking member 331. The engagement of the first locking member 321 with the second locking member 331 is a prior art structure, which will not be described in detail here. Optionally, the backrest pad 31 is made of a flexible material, fits the operator's back, provides comfortable support and cushioning, reduces the pressure of the safety belt 3 on the body, and improves the wearing comfort.

[0057] Furthermore, the safety belt 3 further includes two leg loops 34, both of which are connected to the bottom of the backrest pad 31. The leg loop 34 on the left side is used to pass through the left leg of the human body, and the leg loop 34 on the right side is used to pass through the right leg of the human body, further improving the binding firmness between the human body and the safety belt 3, ensuring that the operator's body is fully protected in the event of an accident.

[0058] Furthermore, a first anti-skid structure is provided on a side of the first positioning member 42 close to the rotating disk 41; and / or a second anti-skid structure is provided on a side of the second positioning member 43 close to the rotating disk 41. By adding the first anti-skid structure and the second anti-skid structure, it is helpful to increase the friction force of the first positioning member 42 and the second positioning member 43 on the rotating disk 41.

[0059] Furthermore, a third anti-skid structure is provided on the circumferential wall of the rotating disk 41. The third anti-skid structure is provided to increase the friction force when the rotating disk 41 contacts the first positioning member 42 and the second positioning member 43.

[0060] In summary, the working principle and use process of the emergency landing device for power grid towers are as follows: when the operator is working at high altitude, the first strap 32 and the second strap 33 are fixed to the operator's body through the clamping connection of the first locking member 321 and the second locking member 331. When the position of the safety belt 3 needs to be adjusted, the rotation drive module 27 is started. The rotation drive module 27 drives the storage roller 22 to rotate through the spline connection. During the rotation of the storage roller 22, the pulling rope 23 is retracted and released, so that the safety belt 3 rises or falls to a suitable position, which is convenient for the operator to wear and adapts to the needs of operators of different heights and working scenarios. The operator can put on the safety belt quickly and conveniently, thereby improving work efficiency.

[0061] The linear drive module 56 is started. When the linear drive module 56 is extended or retracted, the power rod 53 is driven to rotate around the second axis 251. The rotation of the power rod 53 drives the second connecting rod 54 to rotate. The toggle rod 55 at the top of the second connecting rod 54 rotates with it. Since the second positioning member 43 is connected to the top surface of the toggle rod 55, the rotation of the toggle rod 55 causes the second positioning member 43 to generate relative movement on one side of the rotating disk 41. At the same time, the rotation of the power rod 53 is transmitted to the rotating rod 51 through the first connecting rod 52. The rotating rod 51 rotates around the first axis 241, driving the second connecting rod 54 connected to it. The first positioning member 42 generates relative movement on the other side of the rotating disk 41, and the distance between the first positioning member 42 and the second positioning member 43, which are arc-shaped and distributed on the same vertical horizontal line on both sides of the rotating disk 41, changes. When the distance becomes smaller, the friction force on the rotating disk 41 increases. Since the rotating disk 41 is fixedly connected to the storage roller 22, the rotation speed of the storage roller 22 is limited, so that the safety belt 3 is in a tight state. When the distance becomes larger, the friction force on the rotating disk 41 decreases, the rotation speed of the storage roller 22 is accelerated, and the landing speed of the operator is accelerated. In this way, the control of the speed limiting mechanism unit by the adjustment unit 5 is realized to adjust the landing speed of the operator and the emergency braking function.

[0062] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
