The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

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

[0029] like Figure 1 , Figure 2 A line pole anti-falling device shown in the figure includes a shell 100, a rotating member 200 and a holding rope 300, wherein an assembly cavity 123 is arranged inside the shell 100, and the shell 100 is provided with a first hanging portion 121, and the first hanging portion 121 is used to hang a safety belt; the rotating member 200 is assembled in the assembly cavity 123; the holding rope 300 has a loop structure, one end of the holding rope 300 is connected to the shell 100, and the other end is wound around the output end of the rotating member 200; wherein the rotating member 200 is used to drive the holding rope 300 to be retracted and extended relative to the output end to change the diameter of the loop structure, and the loop structure is used to hold the line pole tightly. In actual application, the holding rope 300 is wrapped around the outside of the line pole, and then the holding rope 300 is wound around the output end of the rotating member 200, and the rotating member 200 is started to tighten the holding rope 300 so that the holding rope 300 holds the line pole tightly and then fixes the line pole anti-fall device on the line pole; when the staff is climbing the pole, the line pole anti-fall device can be fixed at any height of the line pole by the above method, so as to provide the staff with a fixing point for the safety belt. The staff does not need to reach the working position to obtain a firm safety belt hanging point, which more comprehensively guarantees the safety of the staff in the climbing operation.

[0030] It is understandable that the holding rope 300 can be made of a material with high wear resistance and poor elasticity (for example, nylon, carbon fiber, hemp rope, etc.), which can enhance the friction between the holding rope 300 and the surface of the line pole and avoid the undesirable phenomenon of the holding rope 300 sliding when subjected to force. Usually, the line pole is usually arranged in the vertical direction, and the structure of the line pole itself is a structure that gradually tapers from bottom to top. The poor elasticity of the holding rope 300 can prevent the holding rope 300 from being greatly stretched due to force after the holding rope 300 is tightly held on the line pole. If the holding rope 300 is stretched too much, the diameter of the loop structure formed by the holding rope 300 will become larger, and then it may slide along the line pole, which will cause a relatively serious safety hazard to the staff's climbing operation. Therefore, the holding rope 300 uses a material with poor elasticity to well ensure the safety of the staff's operation.

[0031] The following will introduce the technical details of each component one by one.

[0032] In some embodiments, Figure 1 , Figure 2As shown, a hook 400 is provided between the holding rope 300 and the housing 100, and the housing 100 is also provided with a second hanging portion 122, and the holding rope 300 is detachably connected to the second hanging portion 122 through the hook 400. In practical applications, when the line pole anti-falling device is in effect, a relatively large interaction force will be generated between the holding rope 300 and the line pole, so that the holding rope 300 and the surface of the line pole will have frequent friction. In addition, during the use of the holding rope 300, there will also be a lot of friction with other components of the line pole anti-falling device. After a long time, the holding rope 300 will be worn, thereby affecting the strength of the holding rope 300, so that the holding rope 300 may be easily broken during use, thereby threatening the safety of the climbers. By providing the hook 400, the holding rope 300 can be very conveniently removed from the housing 100 to replace a new holding rope 300, which is conducive to maintaining the stability of the line pole anti-falling device during use.

[0033] In some embodiments, Figure 2 , Figure 3 , Figure 4 As shown, the rotating member 200 includes a motor 21, a winch 22 and an energy member 23. The winch 22 is connected to the output end of the motor 21, and the energy member 23 is electrically connected to the motor 21. The winch 22 is used to retract and release the holding rope 300. The energy member 23 is a battery for storing electrical energy to drive the rotating member 200 to retract and release the holding rope 300. The motor 21 is controlled by a switch, and the staff can control the rotation direction and start and stop of the motor 21 through the switch. When the line pole anti-fall device needs to be fixed on the line pole, the motor 21 is rotated forward through the switch to tighten the holding rope 300. When the line pole anti-fall device needs to be disassembled, the motor 21 is controlled to reverse through the switch to loosen the holding rope 300, and then the hook 400 is unlocked. The above method can be used to more conveniently install and disassemble the line pole anti-fall device. Figure 5 As shown, an anti-skid protrusion 04 is provided on the output end of the motor 21, and an anti-skid groove 05 is provided on the capstan 22. The anti-skid protrusion 04 is clamped in the anti-skid groove 05 to prevent slipping between the output end of the motor 21 and the capstan 22.

[0034] In other embodiments, the line pole anti-falling device is further provided with a locking mechanism, which is provided between the winch and the housing, and can be moved from an unlocked state to a locked state. When the locking mechanism is in the locked state, the rotation of the winch 22 is restricted, and when the locking mechanism is in the unlocked state, the winch 22 can be rotated under the drive of the motor 21. Through the above design, when the holding rope 300 is tightly held on the line pole, the locking mechanism moves from the unlocked state to the locked state to prevent the winch 22 from rotating, so that the holding rope 300 can be prevented from loosening due to the reversal of the winch 22 after the holding rope 300 is tightly held on the line pole, and the safety of the workers when performing the pole climbing operation is further ensured.

[0035] Specifically, the winch 22 and the shell 100 are both provided with sockets, and the sockets on the winch 22 and the shell 100 can be arranged relative to each other; a latch is arranged between the winch 22 and the shell 100; when the motor 21 drives the winch 22 to make the holding rope 300 hold the line pole tightly, the latch can be moved so that the latch is inserted into the sockets of the winch 22 and the shell 100, thereby forming the above-mentioned locking mechanism to limit the rotation of the winch 22.

[0036] In other embodiments, a worm gear transmission mechanism is arranged between the motor 21 and the winch 22. The worm gear transmission mechanism can prevent the winch 22 from rotating under the pulling action of the holding rope 300, thereby preventing the winch 22 from reversing and causing the holding rope 300 to loosen, thereby further ensuring the safety of the workers when performing pole climbing operations.

[0037] In other embodiments, the line pole anti-fall device includes a brake slider, which is slidably connected to the housing 100, and the brake slider can move from an open state to a stuck state. When the brake slider is in the stuck state, the brake slider is pressed against the holding rope 300 to prevent the holding rope 300 from moving. When the brake slider is in the open state, the movement of the holding rope 300 is not restricted. In the above manner, when the motor 21 drives the winch 22 to hold the holding rope 300 and the line pole tightly, the brake slider can move to a stuck state to clamp and fix the holding rope 300, so as to prevent the holding rope 300 from moving and loosening due to external forces when the holding rope 300 is holding the pole. Furthermore, the contact portion between the brake slider and the holding rope 300 is set in a sawtooth structure to bite the holding rope tightly to prevent the holding rope 300 from slipping.

[0038] Please refer again Figure 2 , Figure 3 , Figure 4The winch 22 comprises a first portion 221 and a second portion 222 which are arranged opposite to each other, a twisting groove 03 is formed between the first portion 221 and the second portion 222, and the first portion 221 and the second portion 222 are detachably connected. The holding rope 300 is located at the rotating member 200 and is pressed between the first portion 221 and the second portion 222. If the holding rope 300 is stuck, the holding rope 300 can be removed from the winch 22 by disassembling and separating the first portion 221 and the second portion 222.

[0039] In some embodiments, an adjusting member 223 is disposed between the first portion 221 and the second portion 222 , and the adjusting member 223 is used to adjust the relative position between the first portion 221 and the second portion 222 to change the width of the splicing wire groove 03 .

[0040] like Figure 2 , Figure 3 As shown, the adjusting member 223 is a screw, one end of the adjusting member 223 is threadedly connected to the second part 222, and the other end is in contact with the first part 221. By rotating the adjusting member 223, the distance between the first part 221 and the second part 222 can be adjusted, thereby changing the width of the twisted wire groove 03. In actual use, since the holding rope 300 is flexible, some of its physical properties will change after long-term use, resulting in a decrease in the degree of compression between the holding rope 300 and the winch 22, thereby reducing the friction. In addition, the friction between the winch 22 and the holding rope 300 will cause the holding rope 300 and the winch 22 to wear, thereby also causing a decrease in the degree of compression between the holding rope 300 and the winch 22, thereby reducing the friction. At this time, the distance between the first part 221 and the second part 222 can be reduced by tightening the adjusting member 223 to increase the pressure between the winch 22 and the holding rope 300. In this way, the winch 22 can be quickly adjusted, thereby maintaining sufficient friction between the winch 22 and the holding rope 300 to prevent slipping.

[0041] It should also be noted that different holding ropes 300 may be made of different materials, and the thickness of different holding ropes 300 may also be different. By adjusting the distance between the first part 221 and the second part 222 by the above-mentioned adjustment member 223 to change the width of the twisted wire groove 03, the winch 22 can be adapted to holding ropes 300 of various diameters and materials.

[0042] In order to further increase the friction between the winch 22 and the holding rope 300, the inner wall of the twisted wire groove 03 is provided with a protrusion structure or a groove structure.

[0043] In some embodiments, the width of the twisted wire groove 03 gradually increases from the axis to the edge of the winch 22. Through the above structure, the closer the holding rope 300 is to the axis of the winch 22, the greater the pressure it bears, and thus the greater the friction between the winch 22 and the holding rope 300. It can be understood that when the winch 22 is tightening the holding rope 300, the holding rope 300 will tend to move toward the axis of the winch 22 under the action of the tensioning force, making it less likely for the holding rope 300 and the winch 22 to slip. In addition to the above effects, the structure of the twisted wire groove 03 can also allow the winch 22 to adapt to a variety of holding ropes 300 with different diameters.

[0044] In some embodiments, a reduction mechanism is provided between the motor 21 and the winch 22, and the input end of the reduction mechanism is connected to the output end of the motor 21 to increase the output torque of the motor 21, and the output end of the reduction mechanism is connected to the winch 22, so that the winch 22 can obtain a larger torque to tighten the holding rope 300, thereby allowing the holding rope 300 to be more firmly clamped on the line pole; at the same time, the reduction mechanism can also reduce the load of the motor 21, thereby extending the service life of the motor 21.

[0045] In some embodiments, Figure 3 , Figure 4 As shown, the assembly chamber 123 includes a first chamber 01 and a second chamber 02, a partition is provided between the first chamber 01 and the second chamber 02 to separate the first chamber 01 and the second chamber 02, the energy component 23 is provided in the first chamber 01, the motor 21 is at least partially provided in the first chamber 01, the output end of the motor 21 passes through the partition and extends to the second chamber 02, the capstan 22 is provided in the second chamber 02 and connected to the output end of the motor 21. In the above manner, the energy component 23 and the main body of the motor 21 can be provided in separate chambers with the capstan 22. As a moving component, the capstan 22 may interfere with and damage the fixed component if placed in the same chamber with the fixed component, and the energy component 23 is a battery, which may cause dangerous situations such as fire if damaged, so the above-mentioned sub-chamber setting method is conducive to ensuring the stability of the work between the various components. Furthermore, since the winch 22 is connected to the external environment, foreign matter in the external environment may enter the assembly cavity 123 . Therefore, the motor 21 and the energy component 23 are arranged in separate chambers, which can provide good protection for the motor 21 and the energy component 23 .

[0046] It is understandable that during the use of the line pole anti-fall device, the shell 100 will need to withstand a large force, and the arrangement of the above-mentioned multiple chambers can also enhance the strength of the shell 100 to improve the bearing capacity of the shell 100.

[0047] In some embodiments, Figure 1 , Figure 2As shown, the housing 100 includes a cavity 12 and a cover 11, the cover 11 is movably connected to the cavity 12, the cover 11 is arranged on a side of the housing 100 close to the second chamber 02, and the cover 11 can move from a first predetermined state to a second predetermined state; wherein, when the cover 11 is in the first predetermined state, the cover 11 closes the second chamber 02, and when the cover 11 is in the second predetermined state, the second chamber 02 is connected to the external environment. In the above manner, when the winch 22 needs to be adjusted and repaired, the cover 11 is moved to the second predetermined state, at which time most of the winch 22 is in an exposed state, and can be operated very conveniently; when in use, the cover 11 is in the first predetermined state, which can prevent external objects from interfering with or damaging the winch 22. In addition to the above effects, the movable design of the cover 11 can also facilitate the operation of the adjustment member 223, thereby enhancing the convenience of using the line pole anti-fall device.

[0048] In other embodiments, Figure 1 , Figure 2 As shown, the housing 100 is provided with a supporting portion 13, which is used to support the line pole when the line pole anti-falling device is fixed on the line pole. The supporting portion 13 is an arc structure and can fit with the surface of the line pole to reduce shaking.

[0049] Furthermore, in order to enhance the friction between the abutting portion 13 and the surface of the line pole, a side of the abutting portion 13 facing the line pole is provided with an anti-skid pad, which may be made of hard rubber.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
