Abstract
Description
Technical Field
[0001] This application relates to the technical field of maintenance of overhead line cement poles, and in particular to a fall prevention device. Background Art
[0002] As one of the key structures for supporting overhead conductors, cement poles are widely used in the erection of urban and rural power lines. During the construction, maintenance, and emergency repair of power lines, operators need to climb the poles to complete high-altitude operations. Currently, foot clips are commonly used as climbing tools, and a safety belt is tied around the waist as fall prevention protection. The safety belt realizes the backward protection in the horizontal direction through the friction force generated by surrounding the pole, and its attached protection rope can only be fixed to the cross arm when the person reaches the top of the pole.
[0003] There are mainly two deficiencies in the existing fall prevention technologies: First, traditional safety devices are difficult to flexibly adjust the structural dimensions to adapt to cement poles of different diameters, resulting in a decrease in protection stability when the pole diameter changes; Second, when the foot clip slips and the person falls, only relying on the elastic deformation of the safety belt itself to buffer the falling impact force, it can neither achieve automatic locking nor has a mechanism to actively recover the safety belt. These two technical defects directly restrict the safety guarantee ability of high-altitude operations. Especially in the operation scenarios where large lifting equipment cannot reach in complex terrains, there is an urgent need to develop a more adaptable and actively protective technical solution. Summary of the Invention
[0004] In view of this, this application provides a fall prevention device, mainly aiming to solve the technical problems that traditional safety devices are difficult to flexibly adjust the structural dimensions to adapt to cement poles of different diameters and only rely on the elastic deformation of the safety belt itself to buffer the falling impact force.
[0005] This application provides a fall prevention device, including:
[0006] A main pole;
[0007] A pole holding ring, one end of which is connected to the main pole;
[0008] A buckle, which is arranged at the other end of the pole holding ring, the pole holding ring passes through the buckle, and the buckle abuts against the main pole;
[0009] A motor, which is arranged at the end of the main pole;
[0010] A hanging ring, which is connected to the motor.

[0018] In a feasible implementation, the device further includes:
[0019] An anti-slip pad, which is arranged on one side of the middle end of the pole-holding ring facing the main rod.
[0020] In a feasible implementation, the number of the pole-holding rings is two.
[0021] In a feasible implementation, the device further includes:
[0022] Bolts, which are arranged at one end of the pole-holding ring passing through the buckle, the bolts are in contact with the buckle, and the number of the bolts is two.
[0023] In a feasible implementation, the device further includes:
[0024] A fixing member, one side of which is connected to the output shaft of the motor, and the other side of which is connected to the hanging ring.
[0025] In a feasible implementation, the device further includes:

[0028] This application provides a fall prevention device, including: a main rod; a pole-holding ring, one end of which is connected to the main rod; a buckle, which is arranged at the other end of the pole-holding ring, the pole-holding ring passes through the buckle, and the buckle is in contact with the main rod; a motor, which is arranged at the end of the main rod; a hanging ring, which is connected to the motor.
[0029] This application adapts to different pole diameters through a main pole structure with adjustable length; utilizes a unique design of a motor and a rigid connection hanging ring to achieve instant self-locking during a fall to provide active protection, and actively retracts the safety belt when needed; and cooperates with the structure of double pole-holding rings, buckles, bolts, and anti-slip pads to ensure stable installation on the pole. This solves the core technical defects in the prior art, such as poor size adaptability, only passive buffering without self-locking function, and lack of active retraction mechanism, and significantly improves the safety and convenience of high-altitude operations on power line poles.

[0039] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.
[0040] In the present application, unless otherwise clearly specified and limited, the terms "install", "connect", "couple", "fix", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0041] In the high-altitude operation of cement poles, the currently used anti-falling devices have significant deficiencies: First, the size adjustment mechanism is cumbersome to operate and prone to loosening, making it difficult to provide stable support on poles with varying diameters or complex pole bodies; Second, its anti-falling mechanism completely relies on the elastic deformation of the safety rope material itself for passive buffering, or on the friction braking principle triggered by the falling speed, lacking the self-locking ability for active response at the moment of falling, and there is a risk of delayed protection; Third, the device completely lacks the active retraction function of the safety belt in the non-falling state, and the arrangement and retraction of the safety rope rely on manual operation, with low efficiency and risks. Therefore, there is an urgent need for an anti-falling device with a deep and stable adjustment structure, which can achieve instant self-locking and active retraction of the safety belt as needed through motor drive, so as to improve the safety protection ability and operation efficiency.
[0042] See Figure 1 and Figure 2 , which shows a schematic structural diagram of an anti-falling device provided by an embodiment of the present application, including:
[0043] Main pole 1;
[0044] Pole-holding ring 2, one end of the pole-holding ring 2 is connected to the main pole 1;
[0045] Buckle 3, which is provided at the other end of the pole ring 2. The pole ring 2 passes through the buckle 3, and the buckle 3 abuts against the main pole 1;
[0046] Motor 4, which is provided at the end of the main rod 1;
[0047] The hanging ring 5 is connected to the motor 4.
[0048] In the above embodiment, one end of the pole ring 2 is fixedly connected to the main pole 1. The other end of the pole ring 2 extends freely and passes through the internal channel of the buckle 3, forming a surrounding structure. The buckle 3 forms an adjustable connection with the pole ring 2 passing therethrough, and through its outer surface, it creates an abutting contact relationship with the corresponding part of the main pole 1, forming a stable constraint. The motor 4 is fixedly mounted in an end area of the main pole 1. The hanging ring 5 is indirectly connected to the output end of the motor 4, so that the rotation or locking state of the hanging ring 5 is controlled by the state of the motor 4.
[0049] This basic structure forms the core of the device's framework and has multiple advantages. The combination of the main pole 1, the pole ring 2, and the buckle 3 forms a constraint frame that can be adapted to cylinders of different diameters. The design in which the motor 4 is arranged at the end of the main pole 1 and rigidly connected to the hanging ring 5 provides the basis for the key fall protection mechanism. The direct connection between the hanging ring 5 and the output end of the motor 4 ensures that when the impact load generated by the safety belt acts on the hanging ring 5, the load can be directly and efficiently transferred to the inside of the motor 4, which is a necessary condition for achieving the subsequent instantaneous locking and active recovery functions. The overall structural layout is reasonable, providing solid support for the stable installation of the device and the realization of its core functions.
[0050] See also Figure 3 , shows a schematic structural diagram of the main rod provided in an embodiment of the present application. Further, the main rod 1 includes:
[0051] a first outer sleeve 11;
[0052] The second outer sleeve 12 is detachably connected to the first outer sleeve 11 .
[0053] In the above embodiment, the main rod 1 is composed of a first outer sleeve 11 and a second outer sleeve 12. A specific detachable connection structure is provided between the first outer sleeve 11 and the second outer sleeve 12, which can be a threaded connection, a snap connection, or a latch connection. This allows the first outer sleeve 11 and the second outer sleeve 12 to be assembled or separated as needed.
[0054] The structure of the first outer sleeve 11 and the second outer sleeve 12 with detachable connection significantly improves the portability and deployability of the device. This structure enables the length of the overall main rod 1 to be disconnected or combined as needed, facilitating transportation and storage while also making it possible to adjust the length of the overall main rod 1 subsequently to adapt to a wider range of rod diameters, solving the inconvenience caused by the integral long rod in traditional devices.
[0055] Furthermore, the main rod 1 further includes:
[0056] A connecting rod 13, which is arranged inside the first outer sleeve 11 and the second outer sleeve 12.
[0057] In the above embodiment, the connecting rod 13 is arranged in the internal space of the first outer sleeve 11 and the second outer sleeve 12. The two ends of the connecting rod 13 are respectively connected to the first outer sleeve 11 and the second outer sleeve 12 or the structural members inside them. In a preferred embodiment, the length of the connecting rod 13 can be selected as needed or adjusted within a certain range.
[0058] The connecting rod 13 arranged inside the outer sleeve provides crucial internal connection force and structural support for the detachable first outer sleeve 11 and second outer sleeve 12. It significantly enhances the overall structural stiffness and bending strength of the main rod 1 in the connected state, ensuring that the main rod 1 has sufficient stability and reliability when bearing the weight of the device, the clamping force of the holding rod ring 2, and possible external impact loads, which is the prerequisite guarantee for the safety protection function.
[0059] Furthermore, the main rod 1 further includes:
[0060] Quick-release latches, which are arranged at the connection positions of the connecting rod 13 with the first outer sleeve 11 and the second outer sleeve 12, and the number of quick-release latches is two.
[0061] In the above embodiment, the quick-release latches can be quick pins or quick wrench clamps, etc., and are arranged at the respective connection positions of the connecting rod 13 with the first outer sleeve 11 and the second outer sleeve 12. Each quick-release latch acts on the corresponding connection point to quickly achieve and firmly lock the relative position relationship between the connecting rod 13 and the corresponding outer sleeve.
[0062] The design of the quick-release latches realizes the efficient and quick locking and release of the connection between the connecting rod 13 and the first outer sleeve 11 and the second outer sleeve 12. This greatly simplifies the installation and disassembly steps, and the overall assembly or length adjustment steps of the main rod 1 can be completed without complex tools, significantly improving the deployment efficiency and use convenience of the device at the operation site, and solving the cumbersome process that requires multiple operation tools in the traditional way.
[0063] Furthermore, the device further includes:
[0064] The anti-slip pad 6 is provided on one side of the middle end of the pole holding ring 2 facing the main pole 1.
[0065] In the above embodiment, the anti-slip pad 6 is attached to the pole holding ring 2 and located on the surface of the middle region of the pole holding ring 2 on the side facing the main pole 1. The anti-slip pad 6 is made of a material with a high coefficient of friction, which can be rubber or polyurethane, etc.
[0066] The anti-slip pad 6 provided at a specific position inside the pole holding ring 2, with its high coefficient of friction characteristic, effectively increases the frictional force at the contact area between the pole holding ring 2 and the pole body when the device holds the pole body tightly. This significantly improves the initial frictional resistance of the device installed on the surface of the pole body, greatly reduces the possibility of accidental sliding or rotation of the device on the pole body, enhances the initial fixing stability of the entire device, and provides a more reliable basis for subsequent operations.
[0067] Furthermore, the number of the pole holding rings 2 is two.
[0068] In the above embodiment, the pole holding rings 2 are two independent structural members provided at the same position. One end of each pole holding ring 2 is respectively connected to the same position on the main pole 1, and the other end passes through the holes on the corresponding buckle 3 and then is adjusted and fixed.
[0069] The design of repeating the arrangement of two pole holding rings 2 greatly enhances the holding force distribution of the device on the pole body and the support stability of the device on the pole body. This double-point support method effectively overcomes the disadvantages that a single pole holding structure is prone to offset or twist when subjected to lateral forces, makes the fixation of the entire device more balanced and firm, and can better adapt to the uneven or irregular surface conditions that the utility pole may have.
[0070] Furthermore, the device further includes:
[0071] Bolts, which are provided at one end of the pole holding ring 2 passing through the buckle 3. The bolts are in contact with the buckle 3, and the number of the bolts is two.
[0072] In the above embodiment, at the free end of the end of the pole holding ring 2 passing through the buckle 3, a specific fastening mechanism, such as an adjusting bolt, is provided. After the bolt is installed, its head can have a contact relationship with the corresponding stop surface on the buckle 3.
[0073] The structure of the bolt provided at the end of the pole holding ring 2 abutting against the buckle 3 provides a convenient and precise tightness adjustment mechanism. The operator can operate the bolt to flexibly and accurately adjust the tightening force formed by the pole holding ring 2 on the pole body, ensuring the most ideal tightening state under various pole diameters, preventing the device from sliding due to being too loose and avoiding difficulties in installation or damage to the pole body surface due to being too tight, and enhancing the adaptability adjustment ability of the device.
[0074] Furthermore, the device further includes:
[0075] A fixing member, one side of the fixing member is connected to the output shaft of the motor 4, and the other side of the fixing member is connected to the hanging ring 5.
[0076] In the above embodiment, the fixing member is located between the motor 4 and the hanging ring 5. One end of the fixing member forms a rigid connection with the output shaft of the motor 4, and the other end thereof forms a rigid connection with the hanging ring 5.
[0077] A special fixing member is provided for intermediate connection, ensuring a high reliability and rigidity of torque transmission between the output shaft of the motor 4 and the hanging ring 5. This design effectively avoids connection looseness, slipping or energy loss that may occur when transmitting a large impact force or operating torque, providing a solid transmission foundation for the hanging ring 5 to achieve an effective self-locking function during falling and a seat belt winding / releasing function during normal operation, and is a technical guarantee for the realization of the core safety function.
[0078] Furthermore, the device further includes:
[0079] A fastener, and the fastener is provided at the connection between the main rod 1 and the holding rod ring 2.
[0080] In the above embodiment, at the connection part where the main rod 1 intersects with the holding rod ring 2, a structure strengthening device, i.e., a fastener, is provided. Such a fastener can be a metal corner, a reinforcing rib plate, a specific welding structure or a combination of high-strength bolt connections, etc., and its function is to increase the structural strength and stiffness of the connection node between the main rod 1 and the holding rod ring 2.
[0081] A special fastener is provided at the key connection point between the main rod 1 and the holding rod ring 2, significantly enhancing the mechanical properties and load-bearing capacity of this joint part. Since this node bears the main impact of the reaction force when the holding rod ring 2 hugs the rod body and the load brought by the user's seat belt, the reinforcement design here effectively prevents deformation, cracking or fatigue damage at the connection, improving the overall structural durability of the device and the safety during long-term use.
[0082] Furthermore, the fastener is also connected to the motor 4, and the fastener is used to reinforce the connection between the holding rod ring 2 and the main rod 1.
[0083] In the above embodiment, the fastener is a structure for strengthening the connection point between the main rod 1 and the holding rod ring 2, and through an additional connection structure, it acts and fastens to the installation base part of the motor 4 at the same time. This enables the fastener to provide an integrated strengthening effect on both the connection point between the main rod 1 and the holding rod ring 2 and the installation point between the main rod 1 and the motor 4.
[0084] The fastener used to connect the main rod 1 and the holding rod ring 2 is extended and designed to also fix the motor 4, maximizing the structural reinforcement effect and achieving integration. This integrated design first further improves the firmness of the connection point between the aforementioned main rod 1 and the holding rod ring 2. More importantly, it significantly enhances the installation stability and impact resistance of the motor 4 at the end of the main rod 1, ensuring that the motor 4 itself will not displace or twist relative to the main rod 1 under large load conditions such as instantaneous fall locking, guaranteeing the reliable operation of the motor 4's functions, and thus improving the response accuracy and effectiveness of the self-locking function of the core protection.

[0086] This application adapts to different pole diameters through the adjustable-length main rod structure; uses the unique design of the motor and the rigidly connected hanging ring to achieve instantaneous self-locking during a fall to provide active protection and actively retract the safety belt when needed; and coordinates with the structure of the double holding rod rings, buckles, bolts, and anti-slip pads to ensure stable installation on the pole. This solves the core technical defects in the prior art, such as poor size adaptability, only passive buffering without self-locking function, and lack of active recovery mechanism, significantly improving the safety and convenience of high-altitude operations on power line poles.
