Description

Technical Field

[0001] This invention relates to the field of wireless communication and terminals, and in particular to a safe tower climbing device and tower climbing system. Background Technology

[0002] With the full coverage of 5G mobile networks, the communication towers used to carry these networks must also undergo equipment upgrades to better optimize the existing mobile networks. These upgrades require communication tower workers to climb the towers to carry out the work.

[0003] Currently, communication towers are generally over forty meters high, but tower workers can only obtain safety protection through safety ropes during the climbing process. This poses certain safety hazards and is not conducive to ensuring the safety of communication tower workers.

[0004] At the same time, relying solely on their own strength to climb communication towers poses a huge challenge to the physical strength and endurance of communication tower workers. Due to limitations in strength and endurance, the speed at which communication tower workers can climb communication towers is relatively limited, which can easily affect the efficiency of work on the communication towers. Summary of the Invention

[0005] In view of the above, embodiments of the present invention provide a safe tower climbing device and tower climbing system to at least solve the technical problems existing in the prior art.

[0006] To achieve the above objectives, the safety tower climbing device described in the embodiments of the present invention includes at least a safety seat and an alternating tower climbing mechanism;

[0007] The safety seat is provided with a traction end, which is used to be connected to a traction device for transmission, so as to pull the safety seat up or down through the traction mechanism;

[0008] The alternating tower climbing mechanism includes at least one group of telescopic limiting components, and each group of telescopic limiting components includes at least two telescopic limiting components; the telescopic limiting components in the same group or different groups move alternately; each telescopic limiting component includes a sliding mechanism, a telescopic component, and a movable limiting mechanism;

[0009] The sliding mechanism includes a fixed part and a sliding part. The fixed part is fixedly installed on the safety seat, and the sliding part is movably connected to the fixed part so that the sliding part can move on the fixed part along the length extension direction of the fixed part.

[0010] The telescopic member is used to extend and retract along a first direction, which is different from the length extension direction of the fixed part. The fixed end of the telescopic member is fixedly connected to the sliding part, and the telescopic end of the telescopic member is fixedly connected to the movable limiting mechanism.

[0011] When the telescopic component extends, the movable limiting mechanism engages with the foot bar of the ladder on the communication tower; when the telescopic component retracts, the movable limiting mechanism disengages from the foot bar of the ladder on the communication tower.

[0012] Optionally, the fixing part is a guide box, the sliding part is a sliding block, and the sliding mechanism further includes an upper liquid bladder, a lower liquid bladder, and a liquid supply assembly;

[0013] The sliding block is slidably installed inside the guide box. The upper liquid bladder is located between the upper side of the inner cavity of the guide box and the upper side of the sliding block. The lower liquid bladder is located between the lower side of the inner cavity of the guide box and the lower side of the sliding block. Both the upper liquid bladder and the lower liquid bladder are connected to the liquid supply assembly.

[0014] Optionally, the movable limiting mechanism includes a limiting frame, a limiting block, and a limiting block drive component;

[0015] The limiting frame is disposed on the telescopic end of the telescopic member, and the limiting frame has a limiting cavity for cooperating with the foot lever and an opening for the foot lever to extend into the limiting cavity.

[0016] The limiting block is movably disposed at the opening of the limiting frame, and has a travel range for extending into the step bar to block the climbing ladder and for moving away from the step bar to avoid the climbing ladder.

[0017] The limiting block drive is disposed on the limiting frame, and the power output end of the limiting block drive is connected to the limiting block in a transmission manner.

[0018] Optionally, the active limiting mechanism further includes a limiting frame drive component;

[0019] The limiting frame drive component is fixedly installed on the telescopic end, and the power output end of the limiting frame drive component is fixedly connected to the limiting frame.

[0020] Optionally, the telescopic limiting components are grouped into at least two groups, and the telescopic limiting components in the same group move synchronously, while the telescopic limiting components in different groups move alternately.

[0021] Optionally, the safety climbing device may also include safety railings;

[0022] The safety guardrails are installed in pairs, and the pairs of safety guardrails are symmetrical and can be rotated and installed on opposite sides of the safety seat;

[0023] The safety guardrail is equipped with a pin mechanism, and the safety seat is equipped with a socket for positioning and engaging with the protruding end of the pin mechanism.

[0024] Optionally, the latch mechanism includes a latch and a latch drive assembly;

[0025] The pin drive assembly is fixedly installed on the safety guardrail, and the pin is fixedly installed on the power output end of the pin drive assembly. The pin constitutes the extended end of the pin mechanism.

[0026] Optionally, the safety climbing device may also include auxiliary mechanisms;

[0027] The auxiliary mechanism includes a storage box, a toolbox, a movable platform, and a movable platform drive assembly. The storage box is fixedly installed below the safety seat and has at least one opening in the horizontal direction. The movable platform drive assembly is fixedly installed on the storage box, and its power output end is connected to the movable platform. The movable platform is guided and slidably installed inside the storage box and has a displacement stroke that extends and retracts from the opening of the storage box. The toolbox is disposed on the mounting platform.

[0028] Optionally, the auxiliary mechanism may further include a lifting mechanism;

[0029] The lifting mechanism includes at least two lifting components arranged in stages. The lifting component at the first stage is installed on the movable platform, and the lifting drive component at the next stage is installed on the lifting end of the lifting component at the previous stage. The toolbox is fixedly installed on the lifting end of the lifting component at the last stage.

[0030] Optionally, the safety seat is also provided with a connecting part for connecting a safety rope.

[0031] This invention also discloses a tower climbing system, which includes a traction device and a safety tower climbing device as described above;

[0032] The traction equipment includes a winch and a pulley block. The winch is installed on the ground, and the pulley block is installed on the communication tower. The traction rope of the winch passes through the pulley block and is connected to the safety tower climbing device.

[0033] Compared with the prior art, the safety tower climbing device and tower climbing system described in the embodiments of the present invention have the following advantages:

[0034] The safety climbing device described in this embodiment of the invention includes at least a safety seat and an alternating climbing mechanism. The safety seat is equipped with a traction end, allowing it to ascend or descend under the traction of a mechanism such as a winch.

[0035] The alternating tower climbing mechanism includes at least one group of telescopic limiting components, and each group of telescopic limiting components includes at least two telescopic limiting components. Specifically, each telescopic limiting component includes a sliding mechanism, a telescopic member, and a movable limiting mechanism. The sliding mechanism can drive the telescopic member and the movable limiting mechanism to move, and the telescopic member can drive the movable limiting mechanism to move. Driven by the sliding mechanism and the telescopic member, the telescopic limiting component can be locked onto the footboard of the communication tower's climbing ladder, and can also be released from the locking engagement and move away from the footboard of the climbing ladder. During the ascent and descent of the safety seat, the telescopic limiting component can prevent the safety seat from suddenly stalling by engaging with the footboard of the climbing ladder through the movable limiting mechanism.

[0036] The telescopic limiting components move alternately between the same group or different groups, which ensures that during the raising and lowering of the safety seat, the movable limiting mechanism of the telescopic limiting component always cooperates with the step bar of the tower's climbing ladder, thereby ensuring the safety protection of the safety seat during the raising and lowering process.

[0037] The safety tower climbing device described in this embodiment of the invention can complete tower climbing with the help of an external mechanism. Compared with manual tower climbing, this significantly increases the climbing speed of the workers, thereby improving their work efficiency. During the ascent and descent of the safety seat, the movable limiting mechanism of the telescopic limiting component always cooperates with the step bar of the tower's climbing ladder, thus preventing the safety seat from suddenly losing speed and further ensuring the personal safety of the workers.

[0046] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] This invention provides a safe tower climbing device, which can be referred to. Figure 2 As shown, this safety climbing device is mainly used in the climbing of communication towers. In some cases, it can also be used for climbing water towers, power towers, industrial chimneys, tall buildings, and other tall structures with ladders. The structure of ladder 2 is that of a common industrial ladder; see reference for details. Figure 5 As shown, the climbing ladder 2 includes two vertically arranged main components and multiple step bars 3 arranged in parallel between the main components.

[0048] For reference Figure 1 and Figure 3As shown, the safety tower climbing device specifically includes a safety seat and an alternating climbing mechanism. In this embodiment, the structure of the safety seat is similar to that of a common seat, specifically including a backrest 7 and a seat 8. When climbing, the worker can sit on the seat 8 and lean against the backrest 7. This improves the comfort of the safety tower climbing device, helps the worker conserve energy, and is beneficial to improving the efficiency of subsequent operations. The backrest 7 also provides safety protection behind the worker, preventing accidental falls from the back of the safety seat.

[0049] The child safety seat is equipped with a traction end, which is used to connect with a towing device to raise or lower the seat. The traction end can be a portion of the backrest 7 or a portion of the seat 8. The specific number, location, and structure of the traction ends depend on the actual needs. For example, if the towing device is a winch 4, the winch 4 can raise or lower the child safety seat by directly fixing it to the seat with a traction rope 5. Based on this lifting scenario, the traction end can be the upward-facing end of the backrest 7, the edge of the seat 8, or a protrusion or groove on the backrest 7 or seat 8. These will not be listed in detail here.

[0050] The alternating climbing mechanism includes at least one group of telescopic limiting components, and each group includes at least two telescopic limiting components. These telescopic limiting components can engage with the footrests 3 of the climbing ladder 2 during the raising or lowering of the safety seat to prevent the safety seat from stalling. The telescopic limiting components move alternately between the same group or different groups; that is, after one telescopic limiting component engages with the footrest 3 of the climbing ladder 2, another telescopic limiting component begins to move to the next or previous footrest 3, until that telescopic limiting component engages with the next or previous footrest 3.

[0051] Specifically, if the alternating climbing mechanism consists of only one group of telescopic limiting components, these components can operate alternately. During ascent, once one telescopic limiting component engages with the footboard 3 of the climbing ladder 2, the other telescopic limiting component can move to the next higher footboard 3. After the next telescopic limiting component engages with the previous footboard 3, the previous telescopic limiting component can move to an even higher footboard 3. This process repeats, ensuring that a telescopic limiting component is always engaged with the footboard 3 of the climbing ladder 2 during the ascent of the safety seat. The alternating movement of the telescopic limiting components during descent is simply the reverse of the ascent process, and will not be elaborated further here.

[0052] For example, when the alternating climbing mechanism includes two or more groups of telescopic limit components, the telescopic limit components within the same group can operate synchronously, while the telescopic limit components between different groups can operate alternately. Alternatively, the telescopic limit components within the same group can operate alternately, while the telescopic limit components between different groups can operate synchronously. Or, the telescopic limit components within the same group can operate alternately, while the telescopic limit components between different groups can also operate alternately. For ease of understanding, this embodiment will be described in detail with a specific example:

[0053] The alternating climbing mechanism comprises two groups of telescopic limiting components, each group containing two telescopic limiting components. These two groups are arranged horizontally and symmetrically relative to the safety seat. One group of telescopic limiting components is positioned above the other. For ease of reference, the upper telescopic limiting component is referred to as the first telescopic limiting component 9, and the lower one as the second telescopic limiting component 10. During ascent, the first telescopic limiting component 9 moves synchronously from its initial position to the next higher step bar 3, while the second telescopic limiting component 10 simultaneously engages with the step bar 3 at its initial position. After the first telescopic limiting component 9 engages with the next higher step bar 3, the second telescopic limiting component 10 moves synchronously towards the next higher step bar 3. After the second telescopic limiting component 10 engages with its next higher step bar 3, the safety seat rises a certain distance under the traction of an external traction device. This process is repeated until the safety seat reaches the predetermined position. When the child safety seat is lowered, the telescopic limit component operates in the reverse of the above process, which will not be described in detail here.

[0054] Alternatively, the above structure can also employ this alternating movement pattern. During ascent, one of the first telescopic limit components 9 moves from its initial position to the next step lever 3, while the other first telescopic limit component 9 remains in its initial position. The second telescopic limit component 10 moves synchronously with its corresponding first telescopic limit component 9 above it. When the safety seat descends, the operation of the telescopic limit components is the reverse of the above process, which will not be elaborated further here.

[0055] Alternatively, during ascent, one of the first telescopic limiting components 9 moves from its initial position to the next-level footrest 3, while the other first telescopic limiting component 9 remains in its initial position. The second telescopic limiting component 10 maintains the opposite movement state to its corresponding first telescopic limiting component 9 above it. That is, if the upper first telescopic limiting component 9 moves to the next-level footrest 3, the second telescopic limiting component 10 below it remains in place; if the upper first telescopic limiting component 9 remains in place, the second telescopic limiting component 10 below it moves towards the next-level footrest 3 relative to itself. When the car seat descends, the operation of the telescopic limiting components is the reverse of the above process, which will not be elaborated further here.

[0056] It is important to emphasize that the statement "the alternating climbing mechanism includes two groups of telescopic limit components, and each group of telescopic limit components includes two telescopic limit components. The two telescopic limit components are arranged symmetrically relative to the safety seat" is merely a specific example for illustrative purposes. In actual implementation, the alternating climbing mechanism may also include one, three, four, or even more groups of telescopic limit components, and each group of telescopic limit components may also include three, four, or even more telescopic limit components. The arrangement of the telescopic limit components depends on specific practical needs and will not be elaborated upon here.

[0057] For reference Figure 3 As shown, the telescopic limiting assembly specifically includes a sliding mechanism, a telescopic component 19, and a movable limiting mechanism. The sliding mechanism includes a fixed part and a sliding part. The fixed part is fixedly installed on the safety seat, and the sliding part is movably installed on the fixed part and can move along the length extension direction of the fixed part. The length extension direction of the fixed part is preferably arranged vertically, or along the height extension direction of the communication tower 1, or inclined relative to the height extension direction of the communication tower 1.

[0058] In this embodiment, the telescopic member 19 can be protected within a storage box 15. Specifically, the storage box 15 is fixedly connected to the aforementioned sliding portion, and the fixed end of the telescopic member 19 is fixedly installed within the storage box 15. The telescopic end of the telescopic member 19 can extend or retract along the first direction X. (See reference...) Figure 3 As shown, the first direction X is different from the length extension direction of the fixed part, and preferably perpendicular to the length extension direction of the fixed part. The telescopic end of the telescopic member 19 is fixedly connected to the movable limiting mechanism. Based on the motion path synthesis of the sliding mechanism and the telescopic member 19, the movable limiting mechanism can engage with the step bar 3 of the ladder 2 on the communication tower 1 when the telescopic member 19 extends, and engage with the step bar 3 of the ladder 2 on the communication tower 1 when the telescopic member 19 retracts.

[0059] Based on the aforementioned structure, the fixing part can be specifically a guide box 11, and the sliding part can be a sliding block 14. The guide box 11 can be a long, narrow box with a long slot on one side for the sliding block 14 to extend out. The sliding part is slidably installed inside the guide box 11, with one end extending out of the long slot and connected to the fixing end of the telescopic member 19.

[0060] For reference Figure 4 As shown, the sliding mechanism also includes an upper liquid bladder 12, a lower liquid bladder 13, and a liquid supply assembly. The upper liquid bladder 12 is disposed between the upper side of the inner cavity of the guide box 11 and the upper side of the sliding block 14, and the lower liquid bladder 13 is disposed between the lower side of the inner cavity of the guide box 11 and the lower side of the sliding block 14. The liquid supply assembly communicates with the upper liquid bladder 12 and the lower liquid bladder 13 to provide liquid medium to the upper liquid bladder 12 and the lower liquid bladder 13.

[0061] The liquid supply assembly may specifically include a liquid tank 16, which is fixedly suspended on the back panel 7 of the child safety seat. A first pump 17 is fixedly connected to the top of the liquid tank 16, with its outlet extending into the interior of the upper liquid bladder 12 to pump liquid media into and out of the upper liquid bladder 12. A second pump 18 is fixedly connected to the bottom of the liquid tank 16, with its outlet extending into the interior of the lower liquid bladder 13 to pump liquid media into and out of the lower liquid bladder 13. When the sliding block 14 needs to move upward, the liquid media in the upper liquid bladder 12 can flow back into the corresponding liquid tank 16 under the action of the first pump 17, while the second pump 18 pumps the liquid media from the corresponding liquid tank 16 into the lower liquid bladder 13. At this time, the upper liquid bladder 12 contracts, the lower liquid bladder 13 expands, and forces the sliding block 14 to move upward. When the sliding block 14 needs to move downwards, the liquid medium in the lower liquid bladder 13 can flow back to the corresponding liquid tank 16 under the action of the second pump 18, while the first pump 17 pumps the liquid medium from the corresponding liquid tank 16 into the upper liquid bladder 12. At this time, the lower liquid bladder 13 contracts, and the upper liquid bladder 12 expands, forcing the sliding block 14 to move downwards. This sliding mechanism, designed based on hydraulic principles, can meet greater load requirements. At the same time, since pumps generally have a certain pressure holding capacity, the above-mentioned sliding mechanism can achieve self-locking of the sliding block 14 to a certain extent.

[0062] Of course, electric cylinders, pneumatic cylinders, hydraulic cylinders, or other power sources capable of outputting linear motion can be used to replace the upper liquid bladder 12 and lower liquid bladder 13. These power sources, along with the upper and lower liquid bladders 12 and 13, are generally arranged on both sides of the sliding block 14. The fixed end of the power source is fixed to the guide box 11, and the power output end is fixedly connected to the sliding block 14. When using an electric cylinder, the aforementioned liquid tank 16 needs to be replaced with a battery; when using a pneumatic cylinder, the aforementioned liquid tank 16 needs to be replaced with a gas cylinder. Furthermore, to save space, in this embodiment of the invention, the synchronously moving telescopic limiting components can share a single liquid tank 16.

[0063] The aforementioned movable limiting mechanism may specifically include a limiting frame 21, a limiting block 23, and a limiting block drive component 22. The limiting frame 21 is disposed on the telescopic end of the telescopic component 19 so that, driven by the sliding mechanism and the telescopic component 19, it can achieve limiting engagement with or disengage from the limiting engagement with the foot bar 3 of the climbing ladder 2 on the communication tower 1.

[0064] For reference Figure 3 and Figure 6 As shown, the limiting frame 21 has a limiting cavity for limiting engagement with the foot bar 3 and an opening for the foot bar 3 of the climbing ladder 2 to extend into the limiting cavity. In this embodiment of the invention, the limiting frame 21 can specifically be a frame structure with a downward-facing opening and a U-shaped cross-section. The limiting block 23 is movably disposed at the opening of the limiting frame 21, and the limiting block drive member 22 is disposed on the limiting frame 21, specifically a hydraulic rod. The power output end of the limiting block drive member 22 is connected to the limiting block 23 to drive the limiting block 23 to move. When the limiting frame 21 is in limiting engagement with the foot bar 3, the limiting block 23 extends below the foot bar 3 and prevents the foot bar 3 from coming out of the opening of the limiting frame 21; when the limiting frame 21 is disengaged from the foot bar 3, the limiting block 23 moves to the side of the foot bar 3 to expose the opening and facilitate the foot bar 3 to come out of the limiting frame 21. Of course, the opening of the limiting frame 21 can also face other sides, in which case the arrangement of the limiting block 23 and the limiting block drive 22 remains unchanged.

[0065] For reference Figure 3 As shown, the movable limiting mechanism may further include a limiting frame drive member 46. The limiting frame drive member 46 is fixedly installed on the telescopic end, and the power output end of the limiting frame drive member 46 is fixedly connected to the limiting frame 21. In this embodiment, the limiting frame drive member 46 can be a telescopic rod. The fixed end of the telescopic rod is fixedly connected to the telescopic end of the aforementioned telescopic member 19 through a connecting arm 20, and the telescopic end of the telescopic rod is fixedly connected to the limiting frame 21 as the power output end. The extension direction of the power output end of the limiting frame drive member 46 depends on the opening direction of the limiting frame 21. In this embodiment, the opening of the limiting frame 21 is arranged downward, so the extension direction of the power output end of the limiting frame drive member 46 is arranged vertically. When the limiting frame 21 disengages from the step bar 3, the limiting frame drive member 46 can pre-lift the limiting frame 21, and then, driven by the telescopic member 19 and the sliding mechanism, further move it away from the step bar 3 to prevent the limiting frame 21 from interfering with other structures of the climbing ladder 2 during movement. The limit frame drive component 46 can share the stroke of the sliding mechanism and the telescopic component 19, which can simplify the movement of the sliding mechanism and the telescopic component 19 when climbing the tower, thereby reducing control costs.

[0066] Optionally, the safety climbing device may also include safety railings. Specifically, in this embodiment, the safety railings are arranged in pairs. Each safety railing consists of an upper crossbar 39, a lower crossbar 45, and two uprights 44. The upper crossbar 39 and lower crossbar 45 are arranged horizontally and at intervals, and the two uprights 44 are fixedly connected between the two crossbars. Two rotating platforms 38, arranged vertically and at intervals, are provided on each horizontal side of the backrest 7 of the safety seat. The upper crossbar 39 and lower crossbar 45 are respectively hinged to the corresponding rotating platforms 38. A pin mechanism is provided on the safety railing, and a socket 43 is provided on the safety seat for positioning and engaging with the protruding end of the pin mechanism. When the operator is riding the safety climbing device, the protruding end of the pin mechanism can be pulled out of the socket 43 to open the safety railing. After the operator is seated in the safety seat, the safety railing can be reset, and the protruding end of the pin mechanism can be reinserted into the socket 43 to secure the safety railing to the operator's side. With the protection of safety railings, workers are less likely to fall from the horizontal side of the safety seat, thus the above structure can further ensure the personal safety of workers.

[0067] Based on this, the latching mechanism can specifically include a latch 42 and a latching drive assembly. The latching drive assembly is fixedly installed on the safety guardrail, and the latch 42 is fixedly installed on the power output end of the latching drive assembly. Driven by the latching drive assembly, the latch 42 can be inserted into and removed from the aforementioned insertion hole 43 as the protruding end of the latching mechanism. (See reference...) Figure 3 As shown, in this embodiment of the invention, the pin drive assembly specifically includes a drive housing 40 and a pin drive ball screw 41 screwed onto the drive housing 40. One end of the pin drive ball screw 41 is fixedly connected to the pin 42, and the other end is exposed as a power input end. In use, the operator manually rotates the pin drive ball screw 41, causing the pin 42 to insert into and move out of the aforementioned insertion hole 43 under the drive of the pin drive ball screw 41.

[0068] Safety climbing devices may also include auxiliary mechanisms. (See reference...) Figure 1As shown, the auxiliary mechanism specifically includes a storage box 25, a toolbox 37, a movable platform 28, and a movable platform drive assembly. In this embodiment, the storage box 25 is fixedly installed below the child safety seat, the movable platform drive assembly is fixedly installed on the upper side inside the storage box 25, and the movable platform 28 is slidably installed on the lower side inside the storage box 25. The storage box 25 has at least one opening in the horizontal direction, allowing the movable platform 28 to extend out of the storage box 25 and retract into the storage box 25 from the opening. The movable platform drive assembly includes a first servo motor 26 and a first ball screw 27 rotatably mounted on the inner cavity of the storage box 25. The output end of the first servo motor 26 is connected to one end of the first ball screw 27, and an intermediate component is screwed onto the first ball screw 27. The intermediate component serves as the power output end of the movable platform drive assembly and is fixedly connected to the movable platform 28. The toolbox 37 is disposed on the movable platform 28 so that it can be inserted into or removed from the storage box 25 along with the movable platform 28.

[0069] For reference Figure 1 , Figure 5 As shown, the auxiliary mechanism may further include a lifting mechanism, which includes at least two graded lifting components. In this embodiment, the lifting mechanism has a two-stage structure: the first-stage lifting component is mounted on the movable platform 28, the second-stage lifting drive is mounted on the lifting end of the first-stage lifting component, and the toolbox 37 is fixedly mounted on the lifting end of the second-stage lifting component. Specifically, the first-stage lifting component includes a first vertical rail 29, a second servo motor 32, and a second ball screw 30. The second servo motor 32 is fixedly mounted at the bottom of the inner cavity of the first vertical rail 29, and the second ball screw 30 is rotatably mounted in the inner cavity of the first vertical rail 29. The output end of the second servo motor 32 is connected to the lower end of the second ball screw 30, and a first moving block 31 is screwed onto the second ball screw 30. Driven by the second servo motor 32, the first moving block 31 can move up and down relative to the second ball screw 30.

[0070] The first-stage lifting assembly includes a second vertical rail 33, a third servo motor 34, and a third ball screw 35. The second vertical rail 33 is fixedly connected to the first moving block 31 so that it moves up and down synchronously with the first moving block 31. The third servo motor 34 is fixedly installed at the bottom of the inner cavity of the second vertical rail 33, and the third ball screw 35 is rotatably installed in the inner cavity of the second vertical rail 33. The output end of the third servo motor 34 is connected to the lower end of the third ball screw 35, and a second moving block 36 is screwed onto the third ball screw 35. Driven by the third servo motor 34, the second moving block 36 can move up and down relative to the third ball screw 35. The second moving block 36 is fixedly connected to the toolbox 37 to push the toolbox 37 up and down. The lifting mechanism adopts a structure with at least two lifting assemblies arranged in stages, which can effectively reduce the stroke and load of a single lifting assembly, making the operation of a single lifting assembly more stable and reliable, and less prone to overload or imbalance.

[0071] Of course, it should be noted that in the embodiments of the present invention, the lifting mechanism may include three, four, or even more lifting components arranged in stages. The specific arrangement can be referred to the foregoing and will not be repeated here. In addition, the lifting components may also be powered by cylinders, electric cylinders, hydraulic cylinders, or other power sources.

[0072] Additionally, a connecting part 24 for attaching a safety rope can be provided on the safety seat. After the worker sits in the safety seat, the safety rope can be secured to the connecting part 24 to further ensure their safety. The connecting part 24 can be a protrusion on the safety seat, or it can be a hole, groove, ring, or other structure on the safety seat.

[0073] This invention also provides a tower climbing system. The tower climbing system includes a traction device and a safety tower climbing device as described above.

[0074] For reference Figure 2 As shown, the traction equipment may specifically include a winch 4 and a pulley block 6. The winch 4 is installed on the ground or on a fixed platform similar to the ground. The pulley block 6 is installed on the communication tower 1, and the traction rope 5 of the winch 4 passes through the pulley block 6 and is connected to the safety tower climbing device.

[0075] In this embodiment of the invention, the pulley block 6 can be a fixed pulley block. A horizontally extending support rod is provided on the communication tower 1, and the fixed pulleys in the fixed pulley block are located at the ends of the support rod. Of course, the pulley block 6 can also be a movable pulley block; its specific arrangement depends on actual needs and will not be elaborated here.

[0076] When workers need to climb the tower, they first need to install the winch 4 on the ground near the communication tower 1. Then, the limiting frame 21 of the safety climbing device is pre-positioned and fitted onto the footboard 3 of the climbing ladder 2 on the communication tower 1. That is, the limiting frame 21 of the safety climbing device is first fitted onto the footboard 3, and the limiting block 23 is driven by the limiting block drive 22 to extend under the footboard 3 to prevent the footboard 3 from coming out of the opening of the limiting frame 21. Next, the workers will pass the traction rope 5 of the winch 4 around the pulley block 6, and then connect the end of the traction rope 5 to the back panel 7 of the safety seat. At this point, the installation of the safety climbing device is complete.

[0077] After the safety climbing device installation is completed, the worker rotates outward to open the safety guardrail and sits on the seat plate 8. After the safety guardrail is reset, the worker turns the pin-driven ball screw 41, causing the pin-driven ball screw 41 to drive the pin 42 to insert into the socket 43, thereby fixing the safety guardrail. At this point, the worker's seating phase is complete.

[0078] After the operator is seated, they control the alternating climbing mechanism to move. The alternating climbing mechanism includes two groups of telescopic limit components, each group containing two telescopic limit components. The two telescopic limit components are arranged horizontally and symmetrically relative to the safety seat. One group of telescopic limit components is located above the other. For ease of reference, the telescopic limit component located above is temporarily referred to as the first telescopic limit component 9, and the telescopic limit component located below is referred to as the second telescopic limit component 10. When the first telescopic limit component 9 is activated, the limit block drive member 22 on the first telescopic limit component 9 moves the limit block 23 to the side of the foot bar 3, then the limit frame drive member 46 moves the limit frame 21 upward, and the telescopic member 19 moves the limit frame 21 back to a position where it does not interfere with the climbing ladder 2.

[0079] At this time, on the first telescopic limiting assembly 9, the first pump 17 of the sliding mechanism pumps the liquid medium inside the upper liquid bladder 12 into the liquid tank 16, and the second pump 18 pumps the liquid medium inside the liquid tank 16 into the lower liquid bladder 13. At this time, the sliding block 14 of the sliding mechanism is forced to move upward, driving the telescopic member 19 to move upward to the position of the upper-level step bar 3. The telescopic member 19 pushes the limiting frame drive member 46 to extend, and the limiting frame drive member 46 pushes the limiting frame 21 downward, so that the limiting frame 21 is fitted onto the upper-level step bar 3. Then, the limiting block drive member 22 pushes the limiting block 23 to move below the upper-level step bar 3.

[0080] Next, the second telescopic limiting assembly 10 is activated. The second telescopic limiting assembly 10 moves to the corresponding upper-level step bar 3 in the same manner as the first telescopic limiting assembly 10. Then, the winch 4 is activated to pull the child safety seat up one distance. During this process, in the first telescopic limiting assembly 9 and the second telescopic limiting assembly 10, the second pump 18 of the sliding mechanism pumps the liquid medium inside the lower liquid bladder 13 into the liquid tank 16, and the first pump 17 pumps the liquid medium inside the liquid tank 16 into the upper liquid bladder 12. At this time, the sliding block 14 of the sliding mechanism is forced to move upward, assisting the child safety seat to rise.

[0081] The descent process is simply the reverse of the above process, which will not be elaborated here.

[0082] When the operator needs to retrieve tools from inside the toolbox 37, the first servo motor 26 drives the first ball screw 27 to rotate, which in turn drives the movable platform 28 to move out of the storage box 25. Then, the second servo motor 32 drives the second ball screw 30 to rotate, causing the first moving block 31 to move the second vertical rail 33 and the toolbox 37 upwards. Finally, the third servo motor 34 drives the third ball screw 35 to rotate, causing the second moving block 36 to move the toolbox 37 upwards until it reaches a height accessible to the operator. The process of retrieving the toolbox 37 is the reverse of this process, and will not be described further here.

[0083] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
