Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of power maintenance equipment, and particularly relates to a climbing assisting device for a power transmission line tower. BACKGROUND

[0002] In a power transmission system, power transmission lines are supported by wire towers. With the development of power, the power transmission flow increases, and the transmission voltage increases significantly. Therefore, the existing wire towers are increasingly high, and workers often need to climb the wire towers to perform equipment installation, maintenance, repair and other operations.

[0003] At present, although the existing climbing assisting devices can help workers to complete the climbing task to a certain extent, there are still some deficiencies. For example, some devices rely on pure human power to climb, and workers consume a lot of physical strength and have low work efficiency; some devices use electric or hydraulic power assisting, and have complex structure and high cost, and may have problems such as insufficient reliability, difficult maintenance and the like in complex outdoor environments. Therefore, it is necessary to develop a device which has relatively simple structure, low cost and can effectively provide power assisting for climbing, so as to meet the industry demand. SUMMARY

[0004] The present application mainly provides a climbing assisting device for a power transmission line tower, which is used to solve the technical problems in the background art.

[0005] The technical scheme adopted by the present application to solve the above technical problems is as follows:

[0006] A climbing assisting device for a power transmission line tower, comprising a carabiner, wherein the carabiner is connected with an elastic power assisting mechanism, the elastic power assisting mechanism is connected with a seat frame, and the seat frame is connected with a guide rod.

[0007] The elastic power assisting mechanism is symmetrically arranged on both sides of the seat frame, and the elastic power assisting mechanism comprises a guide rod, one end of the guide rod is connected with the seat frame, a limiting block is arranged on the guide rod, and a spring is sleeved on the guide rod, one end of the spring is indirectly connected with the seat frame through the guide rod, and the other end of the spring is connected with the carabiner through a connecting mechanism.

[0008] Further, the connecting mechanism comprises a connecting block and a connecting groove, the connecting block is provided with a thread, the thread is connected with the end of the spring away from the seat frame, the connecting groove is arranged on the outer side of the carabiner, and the connecting groove is provided with a thread matched with the connecting block.

[0009] Further, the guide rod is a smooth cylinder, the length of the guide rod is greater than the free length of the spring, the diameter of the guide rod is greater than the inner diameter of the spring, and in addition, the end of the guide rod connected with the seat frame is provided with a thread.

[0010] Further, the limiting block is located at the side of the guide rod away from the seat frame and has a size greater than the diameter of the guide rod.

[0011] Further, the seat frame front part is provided with a ring-shaped opening, the ring-shaped opening is provided with a clamping assembly, the seat frame top part is provided with a folding backrest, the seat frame side wall is provided with a mounting hole and a safety buckle connecting point, and the seat frame bottom part is further provided with a supporting pad, and the mounting hole is detachably connected with one end of the guide rod.

[0012] Further, the mounting hole is provided with a nut matched with one end of the guide rod, and the nut can move up and down in the mounting hole.

[0013] Further, the supporting pad is made of wear-resistant rubber and has an arc shape matched with the surface of the pole tower.

[0014] Further, the safety buckle comprises a buckle body mounted on the foot pedal, and the connecting groove of the connecting mechanism is arranged on the foot pedal.

[0015] Further, the buckle body is provided with an adjusting assembly, and the inner side of the buckle body is provided with an anti-skid rubber pad.

[0016] Further, the upper surface of the foot pedal is provided with anti-skid lines, and the foot pedal is further provided with a locking assembly.

[0017] Compared with the prior art, the present application has the following advantages:

[0018] Firstly, the present application sets an elastic power assisting mechanism, which uses the elastic property of the spring to provide power assistance for climbing. When the staff member presses down the seat frame, the spring is compressed to store elastic potential energy. After the pressing down action is released, the spring restores to its original state to generate an upward elastic force, which is accurately transmitted to the safety buckle through the connecting mechanism to drive the safety buckle to move upward. Through such a cycle operation, the staff member can use the power assistance to more easily lift the safety buckle for climbing, effectively reducing the physical exertion during the climbing of the pole tower and improving the climbing efficiency.

[0019] Secondly, the inner side of the buckle body in the safety buckle is provided with an anti-skid rubber pad made of rubber material with high friction coefficient, which can closely fit the surface of the pole tower to effectively prevent the safety buckle from sliding on the pole tower. The upper surface of the foot pedal is provided with anti-skid lines to increase the friction between the staff member's foot and the foot pedal, preventing the foot from sliding on the foot pedal. These two anti-skid measures ensure the stability of the staff member during the climbing process from different angles, reducing the risk of accidents caused by sliding. The foot pedal is further provided with a locking assembly, which adopts a buckle type locking mode, is simple to operate, firmly locked, and convenient to unlock. After the staff member places his foot on the foot pedal and adjusts the position, he can fix the foot by operating the locking assembly to prevent the foot from accidentally falling during the climbing process, further enhancing the safety.

[0020] Thirdly, the seat frame side wall is provided with a safety buckle connecting point, and the worker can connect the safety belt worn by himself to the connecting point when climbing. Even if an accident occurs during climbing, causing the body to lose balance or the seat frame, the carabiner and other components to malfunction, the safety belt can fix the worker on the seat frame to prevent falling from a high place, greatly improving the safety of climbing operations. The support pad at the bottom of the seat frame is made of wear-resistant rubber, which is compatible with the surface of the power pole tower. It can not only enhance the stability of the contact between the seat frame and the power pole to prevent the seat frame from sliding on the power pole, but also maintain its integrity and functionality during long-term friction to avoid safety hazards caused by seat frame sliding.

[0021] Fourthly, the seat frame and the guide rod of the present application are detachably connected through the mounting hole and the nut. This connection provides a certain flexibility. When installing the device, the end of the guide rod can be easily inserted into the mounting hole, and then fastened with a nut. When maintenance, replacement of parts or storage is needed, the nut can be easily unscrewed, and the guide rod can be removed from the mounting hole. The operation is relatively convenient, and the difficulty of device installation, maintenance and storage is reduced. The connecting mechanism is detachably fixed by inserting the connecting block into the connecting groove on the outside of the carabiner and using threads. This connection realizes firm connection with the carabiner. This connection method not only ensures that the spring force is accurately transmitted to the carabiner, but also facilitates inspection, maintenance or replacement of parts when needed.

[0032] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0033] Example

[0034] Please refer to the appendix carefully. Figure 1 , 4 As shown, a climbing aid device for power transmission line towers includes a foot buckle 1, an elastic assist mechanism 2 connected to the foot buckle 1, and a base frame 3 connected to the elastic assist mechanism 2. The elastic assist mechanism 2 is symmetrically arranged on both sides of the base frame 3. The elastic assist mechanism 2 includes a guide rod 201, one end of which is connected to the base frame 3 and is threaded. A limiting block 202 is provided on the guide rod 201, and a spring 203 is sleeved on the guide rod 201. One end of the spring 203 is indirectly connected to the base frame 3 through the guide rod 201, and the other end is connected to the foot buckle 1 through a connecting mechanism 4. The connecting mechanism 4 includes a connecting block 401 and a connecting groove 402. The connecting block 401 is threaded and is connected to the end of the spring 203 away from the base frame 3. The connecting groove 402 is located on the outside of the foot buckle 1 and is threaded to match the connecting block 401.

[0035] It should be noted that the guide rod 201 is an important part of the elastic power assisting mechanism 2, which plays a key role in providing guidance for the spring 203 and limiting its activity range. The guide rod 201 is made of high-strength stainless steel, which is cylindrical in shape and has a highly smooth surface after fine machining. The length of the guide rod 201 is greater than the free length of the spring 203, ensuring that the spring 203 can move within its effective range in both fully stretched and maximum compressed states, avoiding abnormal situations such as spring 203 disengagement. The diameter of the guide rod 201 matches the inner diameter of the spring 203, so that the spring 203 can be tightly fitted on it, and during the extension and contraction of the spring 203, it can provide accurate guidance for the spring 203, ensuring that the spring 203 moves in an orderly manner along the guide rod 201, preventing irregular deformation such as lateral bending or twisting. The guide rod 201 is detachably connected to the seat frame 3 at one end through threads, ensuring that it does not loosen or shift during use. The other end is provided with a limiting block 202 whose size is greater than the diameter of the guide rod 201, which is used to prevent the spring 203 from being compressed too much.

[0036] It should be noted that the spring 203 is the core component of the elastic power assisting mechanism 2, which undertakes the important task of storing and releasing elastic potential energy. It is made of high-strength alloy spring steel, such as 60Si2Mn (silicon manganese spring steel) and other materials, which has good elasticity and fatigue resistance. This material can maintain stable mechanical properties during repeated compression and rebound, ensuring reliable assistance for the carabiner 1. One end of the spring 203 is indirectly connected to the seat frame 3 through the guide rod 201, specifically by being fitted on the guide rod 201, and establishing a connection relationship with the seat frame 3 through the guide rod 201. When the staff presses down the seat frame 3, the displacement of the seat frame 3 will be transmitted to the spring 203 through the guide rod 201, causing the spring 203 to be compressed. The other end of the spring 203 is connected to the carabiner 1 through the connecting mechanism 4, so that when the spring 203 returns to its original state and generates an upward elastic force, it can transmit the elastic force to the carabiner 1 and push the carabiner 1 upward, providing assistance for the staff's climbing.

[0037] It should be noted that the wire diameter, outer diameter, and number of turns of the spring 203 are determined according to the actual required assistance size and the overall size of the device and other factors. Specifically, the size of the wire diameter affects the strength and elastic properties of the spring 203, the outer diameter determines the overall size of the spring 203 and its relationship with other components, and the number of turns is closely related to the elastic potential energy that the spring 203 can store. By reasonably adjusting these parameters, it can ensure that the spring 203 can provide sufficient assistance for climbing while ensuring its stability and reliability during compression and recovery.

[0038] It should be noted that the connecting mechanism 4 is detachably fixed by inserting the connecting block 401 into the connecting groove 402 outside the climbing shoe 1, and can be supplemented by threads, to realize firm connection with the climbing shoe 1, so as to ensure that the spring 203 can accurately and accurately transmit the elastic force to the climbing shoe 1 when the spring 203 recovers to generate upward elastic force, so that the climbing shoe 1 can obtain upward thrust, and then realize upward movement by means of friction with the telegraph pole, providing power for the climbing of the staff.

[0039] Please refer to Figs. 7 and 8 Figure 5 、 6 , the seat frame 3 is provided with a folding backrest 303 on the top, and the side wall of the seat frame 3 is provided with a mounting hole 304 and a safety buckle connection point 305, and the bottom of the seat frame 3 is also provided with a support pad 306.

[0040] It should be noted that the folding backrest 303 provided on the top of the seat frame 3 provides a certain comfort and support for the staff during climbing. When the staff climbs intermittently or needs to take a short break, the folding backrest 303 can be unfolded for use. It can let the staff rely on it to reduce the feeling of fatigue of the body, especially when climbing for a long time or at a high height, this function is particularly important. Moreover, the folding backrest 303 adopts a foldable design, which can be folded up when not in use, avoiding hindering the normal climbing operation, and also facilitating the storage and carrying of the whole climbing aid device.

[0041] It should be noted that the safety buckle connection point 305 provided on the side wall of the seat frame 3 is an important setting to ensure the safety of the staff. When the staff uses the climbing aid device to climb, the safety belt worn by the staff is connected to the safety buckle connection point 305. In this way, during the climbing process, even if an accident occurs and the staff's body loses balance or the seat frame 3, the climbing shoe 1 and other components fail, the safety belt can still fix the staff on the seat frame 3, preventing the staff from falling from a high place, greatly improving the safety of the climbing operation.

[0042] It should be noted that the support pad 306 provided on the bottom of the seat frame 3 mainly plays a role in enhancing the stability of the contact between the seat frame 3 and the surface of the telegraph pole. The support pad 306 is made of wear-resistant rubber, and its shape is an arc shape that is adapted to the surface of the telegraph pole tower, so as to better fit the surface of the telegraph pole and enhance the contact stability with the telegraph pole. The wear-resistant rubber material has good wear resistance and anti-skid performance, and can maintain its integrity and functionality during long-term contact and friction with the surface of the telegraph pole, without rapid wear and deformation due to frequent friction.

[0043] It should be noted that the mounting hole 304 provided on the side wall of the seat frame 3 plays a key role in the structural connection of the entire climbing aid device. It is detachably connected with one end of the guide rod 201, and the mounting hole 304 is provided with a nut 307 matched with one end of the guide rod 201, which can move up and down in the mounting hole 304. This detachable connection mode realized by the mounting hole 304 and the nut 307 provides a certain flexibility for the connection between the seat frame 3 and the guide rod 201. During the installation of the device, one end of the guide rod 201 can be conveniently inserted into the mounting hole 304, and then fastened by the nut 307 to ensure the firmness of the connection. When the device needs to be repaired, replaced parts or stored, the nut 307 can be easily unscrewed, and the guide rod 201 can be taken out of the mounting hole 304, which is relatively convenient to operate.

[0044] It should be noted that the nut 307 can move up and down in the mounting hole 304, so that when the spring 203 exerts different degrees of force on the guide rod 201 during extension and retraction, the nut 307 can adaptively adjust its position in the mounting hole 304 within a certain range, thereby avoiding stress concentration and other problems that may be caused by rigid connection. This adaptive adjustment helps to maintain the stability of the entire connection structure and ensures that the guide rod 201 can still normally play its guiding role for the spring 203 under the action of various forces, while protecting the mounting hole 304 and the surrounding structure from damage due to excessive stress.

[0045] Please refer to Figs. 1-3 Figure 1 、 2 , 3, the carabiner 1 includes a carabiner body 101 mounted on a foot plate 102, a connecting groove 402 of the connecting mechanism 4 is provided on the foot plate 102, and an adjusting assembly 103 is provided on the carabiner body 101. The inner side of the carabiner body 101 is provided with a non-slip rubber pad 104, the upper surface of the foot plate 102 is provided with non-slip patterns 105, and a locking assembly 106 is further provided thereon.

[0046] It should be noted that the adjusting assembly 103 can adjust the clamping force between the carabiner body 101 and the tower by adjusting the opening angle and the extension length of the carabiner body 101, so that the carabiner 1 can better adapt to towers of different outer diameters and different climbing environments.

[0047] It should be noted that the anti-skid rubber pad 104 arranged inside the buckle body 101 is an important guarantee to ensure the stable adhesion of the foot buckle 1 on the tower. The anti-skid rubber pad 104 is made of rubber material with high friction coefficient, which can closely fit on the surface of the tower and greatly enhance the friction between the foot buckle 1 and the tower. During the climbing process, no matter how the weight of the staff is distributed or how the climbing action changes, the anti-skid rubber pad 104 can effectively prevent the foot buckle 1 from sliding, thereby ensuring the safety of the staff and the continuity of the climbing action.

[0048] It should be noted that the anti-skid pattern 105 arranged on the upper surface of the foot pedal 102 is mainly to increase the friction between the staff's feet and the foot pedal 102. When the staff steps on the foot pedal 102, the anti-skid pattern 105 can prevent the feet from sliding on the foot pedal 102, so that the staff can stand and exert force more stably, which helps to better control the action of the foot buckle 1 during the climbing process. The locking assembly 106 arranged on the foot pedal 102 plays an important role in safety protection and operational convenience. The locking assembly 106 adopts a buckle type locking mode, which is simple to operate, firmly locked, and convenient to unlock, and is convenient for the staff to quickly and accurately operate. After the staff places their feet on the foot pedal 102 and adjusts the position, the staff can fix the feet on the foot pedal 102 by operating the locking assembly 106 to prevent accidental slipping of the feet during the climbing process.

[0049] The specific operation process of the present application is as follows:

[0050] First, according to the outer diameter size of the tower, the opening angle and inner diameter size of the buckle body 101 are adjusted through the adjusting assembly 103, so that the foot buckle 1 can be smoothly fitted on the tower later. Then, the seat frame 3 is fitted on the tower through the annular opening 301 at the front of the seat frame 3. After the seat frame 3 is fitted, the clamping assembly 302 on the annular opening 301 is operated to tightly clamp the seat frame 3 on the tower, preventing the seat frame 3 from shaking or shifting during the climbing process. The guide rod 201 of the elastic power assisting mechanism 2 is removed, and the threaded end of the guide rod 201 is inserted into the mounting hole 304 of the side wall of the seat frame 3. The guide rod 201 is fastened in the mounting hole 304 through the nut 307. The buckle body 101 of the foot buckle 1 is fitted on the tower below the seat frame 3 through its openable structure. After the foot buckle 1 is fitted, the adjusting assembly 103 of the foot buckle 1 is further adjusted according to the outer diameter of the tower. The connecting block 401 on the spring 203 is screwed with the connecting groove 402 on the foot buckle 1, and the connection of the elastic power assisting mechanism 2 and the foot buckle 1 is completed.

[0051] In the process of climbing the pole tower, the worker first connects one end of the safety belt worn by himself to the safety buckle connection point 305 on the side wall of the seat frame 3, ensures the connection to be firm and reliable, and guarantees the personal safety in the climbing process. Then the worker places his feet on the foot pedal 102 of the foot buckle 1, adjusts the foot position to make the center of gravity of the feet be evenly distributed, then operates the locking assembly 106 on the foot pedal 102 to fix the feet on the foot pedal 102, and prevents the feet from accidentally slipping off in the climbing process. When preparing to climb upward, the worker holds the pole tower with his hands, and slightly crouches his body, and presses down the seat frame 3 through the leg force. The action of pressing down the seat frame 3 will make the seat frame 3 produce downward displacement relative to the foot buckle 1. Due to the connection relationship of the elastic power assisting mechanism 2, the displacement of the seat frame 3 will be transmitted to the spring 203 through the guide rod 201, so that the spring 203 is compressed and the elastic potential energy is stored. After pressing down to a certain extent, the worker releases the pressing action. At this time, the spring 203 restores to the original state, and generates an upward elastic force. The elastic force is transmitted to the foot buckle 1 through the connecting mechanism 4, and an upward thrust is applied to the foot buckle 1. The foot buckle 1 converts the thrust into upward moving power by means of the friction with the pole tower, so that the worker can easily lift the foot buckle 1 to climb. After climbing a distance each time, the above pressing and releasing actions can be repeated according to the needs to continuously obtain the power, so that the pole tower can be climbed more easily.

[0052] The above describes the present application by way of example with reference to the drawings. It is obvious that the specific implementation of the present application is not limited by the above method. Any non-essential improvement or direct application of the concept and technical solution of the present application to other occasions is within the protection scope of the present application.
