Description

Technical Field

[0001] The present invention relates to the technical field of fall arresters, and specifically to a portable dismountable tower fall arrester. Background Technique

[0002] With the continuous increase in the demand for high-altitude operations, the construction, maintenance, and related operations of towers increasingly involve the safety protection of high-altitude operators. In high-altitude operations such as towers and communication towers, fall arresters are important devices to ensure the safety of operators. Traditional fall arresters are usually fixed on the guide rails of towers and use mechanical principles to ensure that operators can slow down or prevent falling in case of accidents.

[0003] According to the invention patent with the Chinese patent publication number CN118767364A, whose name is a special fall arrester for climbing towers, it is specifically described as consisting of two sets of fall arrester assemblies. Each fall arrester assembly includes a main handle and a sub-handle that can be hinged. The sub-ring buckle at the end of the sub-handle can be rotationally buckled with the main-ring buckle at the end of the main handle under the elastic force of a spring to achieve fixed hanging installation on the tower foot nails. A safety locking device is also installed between the main handle and the sub-handle. Only after unlocking the safety locking device can the sub-ring buckle be rotationally separated from the main-ring buckle, and the installation method of the fall arrester rope on the main handle and the sub-handle can also prevent the sub-ring buckle from being rotationally separated from the main-ring buckle, thereby further improving the safety performance of the use of this fall arrester. In addition, the special fall arrester for climbing towers is simple to operate, does not require the cooperation of multiple people, has high work efficiency, high reliability, low cost, and is portable, suitable for single-person operations.

[0004] However, the existing portable dismountable tower fall arrester has the following deficiencies:

[0005] 1. Traditional fall arresters usually need to be disassembled or installed from both ends of the tower guide rail, which is very inconvenient in high-altitude operations or complex environments. Especially when it is necessary to frequently adjust the position or install it in different positions, the installation process of traditional fall arresters is complex, requires special tools and a long time, increasing the work burden of operators. Moreover, most traditional fall arresters are designed with fixed sizes and shapes and usually can only be applicable to specific models of tower guide rails. For tower guide rails with different sizes and shapes, traditional fall arresters may not be adaptable, resulting in the need to replace or adjust equipment, increasing the maintenance cost and complexity.

[0006] 2. Dust, dirt, and rust will accumulate on the tower guide rail during use, which may affect the normal operation of the fall arrester. During cleaning, traditional tower guide rails usually need to be manually cleaned regularly. Operators need to climb the tower and manually clean impurities such as dust, dirt, and rust on the surface of the guide rail. The cleaning methods may include using tools such as brooms, brushes, and spray cleaners for surface cleaning, which is time-consuming and laborious, resulting in the inability to promptly remove the dirt on the surface of the guide rail, affecting the friction and contact stability between the fall arrester and the guide rail, and increasing the risk of falling.

[0007] Therefore, we propose a portable tower anti-falling device that can be disassembled and assembled to solve the problems mentioned above. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Through the installation mechanism provided by the present invention, when the user needs to install the anti-falling device body on the iron tower guide rail, the operation becomes more convenient. The user can place the first clamping plate and the second clamping plate on both sides of the iron tower guide rail respectively, and then drive the transmission wheel to rotate by turning the transmission handle. The transmission wheel drives the second telescopic rod to rotate. The rotation of the second telescopic rod then drives the transmission shaft to drive the second transmission helical gear to rotate. The second transmission helical gear meshes with the first transmission helical gear, thereby driving the first vertical wheel to rotate. The first transmission helical gear drives the lead screw to rotate. When the lead screw rotates, the threaded part moves accordingly. At this time, the limiting rod is slidably connected to the limiting support seat, and the second clamping plate and the first clamping plate will approach each other until the two guide wheels completely fit the outer wall of the iron tower guide rail. After that, the user can adjust the transmission wheel to move the second telescopic rod and lock the transmission wheel by inserting the locking rod into the locking groove. When the user accidentally falls, the connecting piece will drive the pre-compressor to descend. The pre-compressor moves the triggering piece. When the triggering piece moves, one side of the triggering piece drives the second transmission gear to rotate. Due to the elasticity of the spring rod, the rack meshes with the other second transmission gear and drives it to rotate. The two second transmission gears respectively drive the two first transmission gears to rotate, thereby driving the two clamping eccentric wheels to rotate. These clamping eccentric wheels will clamp the iron tower guide rail to achieve locking. Traditional anti-falling devices can usually only be disassembled or installed from both ends of the anti-falling guide rail, which is very inconvenient for operations in high-altitude or complex environments. However, the anti-falling device body of the present invention adopts a telescopic structural design, enabling the anti-falling device body to be easily disassembled from the guide rail when needed and quickly installed at other positions. This design saves installation and disassembly time and improves work efficiency, especially suitable for workplaces that require frequent position changes, such as high-altitude operations and iron tower maintenance. Moreover, through the telescopic structure, it can adapt to iron tower guide rails of different sizes and shapes. Whether in a narrow space or a relatively spacious working environment, the anti-falling device body can be flexibly applied to meet various actual needs.

[0023] 2. Through the installation mechanism provided by the present invention, during the installation process, the first clamping plate and the second clamping plate will approach each other, and the locking teeth on the inner side of the locking plate exert a squeezing force on the locking claws. When the positions of the locking teeth and the locking claws are aligned, the return spring will drive the locking claws to rise, causing one end of the locking claws to insert into the inner wall of the locking teeth, thus achieving double insurance. This design effectively prevents the anti-falling device body from loosening or becoming unstable during use, ensuring the safety of the user. The double insurance mechanism provides additional safety protection. Even in the case of a failure of the locking mechanism, the return spring can still drive the locking claws to insert into the inner wall of the locking teeth, further enhancing the reliability and significantly improving the safety, stability, and usability of the anti-falling device body, especially suitable for occasions with extremely high safety requirements such as high-altitude operations.

[0024] 3. The cleaning mechanism of the present invention is arranged. When the fall arrester body moves, the two connecting arms drive the two supporting arms to move respectively. During the movement of the supporting arms, the pressure spring on the inside will push the cleaning brush to fit closely to the inner wall of the iron tower guide rail for effective cleaning. This design can not only remove dust and dirt on the inner wall of the iron tower guide rail, but also avoid affecting the normal use of the fall arrester body due to insufficient friction. The design of the cleaning brush also includes driving the scraper to clean the rust and impurities on the outer wall of the iron tower guide rail. This function can effectively remove rust and impurities that may exist on the surface of the guide rail to prevent them from having an adverse effect on the performance and safety of the fall arrester body, thereby reducing the safety hazards caused by rust or dirt accumulation. The automatic cleaning function can keep the iron tower guide rail clean and ensure the stability and smoothness of the fall arrester body in long-term use. Secondly, the dual cleaning action of the cleaning brush and the scraper effectively eliminates rust, impurities and dirt, avoids insufficient friction caused by problems on the guide rail surface, and improves the contact stability between the fall arrester body and the iron tower guide rail, thereby enhancing safety.

[0038] The mounting mechanism 6 includes a threaded member 616, a screw rod 617, a locking plate 606, a locking tooth 607 and a locking claw 613. The middle part of the threaded member 616 is threadedly connected to the screw rod 617, the bottom end of the locking plate 606 is fixedly connected with the locking tooth 607, and the locking claw 613 is inserted on the inner side of the locking tooth 607.

[0039] Embodiment 1, according to Figures 4 - 10As shown, the installation mechanism 6 further includes a spring rod 603, a first telescopic rod 605, a transmission handle 609, a base 610, a protective box 622, a locking groove 618, a telescopic rod and a limiting rod 612.

The bottom end of the protective box 622 is fixedly connected to the outer wall of the first clamping plate 2. The bottom end of the base 610 is fixedly connected to one side of the outer wall of the first clamping plate 2. The bottom end of the threaded part 616 is fixedly connected to the middle of the second clamping plate 3. The bottom end of the locking plate 606 is fixedly connected to one side of the outer wall of the second clamping plate 3. A return spring 614 is fixedly connected to the bottom end of the locking claw 613. The bottom end of the return spring 614 is fixedly connected to the other side of the outer wall of the first clamping plate 2. A support plate 615 is fixedly connected to the outer wall of the first clamping plate 2. The top end of the support plate 615 is hinged to the locking claw 613. A limiting support 601 is fixedly connected to one end of the first clamping plate 2. A limiting seat 611 is fixedly connected to one end of the second clamping plate 3. A limiting rod 612 is fixedly connected to the outer wall of the limiting seat 611. The outer wall of the limiting rod 612 is slidably connected to the limiting support 601. A trigger member 602 is vertically slidably connected to the bottom end of the second clamping plate 3. A spring rod 603 is fixedly connected to one side wall of the trigger member 602. A rack 604 is fixedly connected to the free end of the spring rod 603. A first telescopic rod 605 is connected between the inner sides of the first clamping plate 2 and the second clamping plate 3. Guide wheels 9 are rotatably connected to the outer walls of both the first clamping plate 2 and the second clamping plate 3. A tower rail 1 is provided between two adjacent guide wheels 9. Transmission gears one 10 are rotatably connected to the outer walls of both the first clamping plate 2 and the second clamping plate 3. A transmission gear two 11 is meshed with the outer side of each transmission gear one 10. A clamping eccentric wheel 8 is fixedly connected to the top end of each transmission gear one 10. One side of the trigger member 602 is meshed with one of the transmission gears two 11. The two transmission gears two 11 are respectively connected to the outer walls of the first clamping plate 2 and the second clamping plate 3. The other transmission gear two 11 is meshed with the rack 604. A pre-pressure device 12 is slidably connected to the outer wall of the first clamping plate 2. A connector 5 is fixedly connected to the outer wall of the pre-pressure device 12.

[0040] The effects achieved by the entire Embodiment 1 are as follows: When the user needs to install the anti-falling device body 7 on the iron tower guide rail 1, the operation becomes more convenient. The user can place the first clamping plate 2 and the second clamping plate 3 on both sides of the iron tower guide rail 1 respectively. Then, by rotating the transmission handle 609, the transmission wheel 608 is driven to rotate. The transmission wheel 608 drives the second telescopic rod 620 to rotate. The rotation of the second telescopic rod 620 then drives the transmission shaft 621 to drive the second transmission helical gear 624 to rotate. The second transmission helical gear 624 meshes with the first transmission helical gear 623, thereby driving the first vertical wheel to rotate. The first transmission helical gear 623 drives the lead screw 617 to rotate. When the lead screw 617 rotates, the threaded part 616 moves accordingly. At this time, the limiting rod 612 is slidably connected to the limiting support 601, and the second clamping plate 3 and the first clamping plate 2 will approach each other until the two guide wheels 9 completely fit the outer wall of the iron tower guide rail 1. After that, the user can adjust the transmission wheel 608 to move the second telescopic rod 620 and insert the locking rod 619 into the locking groove 618 to lock the transmission wheel 608. When the user accidentally falls, the connecting piece will drive the pre-pressure device 12 to descend. The pre-pressure device 12 causes the triggering part 602 to move. When the triggering part 602 moves, one side of the triggering part 602 drives the second transmission gear 11 to rotate. Due to the elasticity of the spring rod 603, the rack 604 meshes with another second transmission gear 11 and drives it to rotate. The two second transmission gears 11 respectively drive the two first transmission gears 10 to rotate, thereby driving the two clamping eccentric wheels 8 to rotate. These clamping eccentric wheels 8 will clamp the iron tower guide rail 1 to achieve locking. Traditional anti-falling devices can usually only be disassembled or installed from both ends of the anti-falling guide rail, which is very inconvenient for operations in high-altitude or complex environments. However, the anti-falling device body 7 of the present invention adopts a telescopic structural design, enabling the anti-falling device body 7 to be easily disassembled from the guide rail when needed and quickly installed in other positions. This design saves installation and disassembly time and improves work efficiency. Moreover, during the installation process, the first clamping plate 2 and the second clamping plate 3 will approach each other, and the locking teeth 607 inside the locking plate 606 exert a squeezing force on the locking claw 613. When the positions of the locking teeth 607 and the locking claw 613 are aligned, the return spring 614 will drive the locking claw 613 to rise, causing one end of the locking claw 613 to insert into the inner wall of the locking teeth 607, thus realizing double-layer insurance. This design effectively prevents the anti-falling device body 7 from becoming loose or unstable during use and ensures the safety of the user. The double-layer insurance mechanism provides additional safety protection. Even in the case of a failure of the locking mechanism, the return spring 614 can still drive the locking claw 613 to insert into the inner wall of the locking teeth 607, further enhancing the reliability and significantly improving the safety, stability, and use convenience of the anti-falling device body 7, which is particularly suitable for occasions with extremely high safety requirements such as high-altitude operations.

[0041] It should be noted that when the user needs to disassemble the anti-falling device body 7, the locking claw 613 needs to be manually pressed. When the locking claw 613 is pressed, the return spring 614 can be compressed, so that the locking claw 613 disengages from the locking tooth 607. During use, the elastic force of the return spring 614 can drive the locking claw 613 to apply force, ensuring that the locking claw 613 can rise and insert into the inner wall of the locking tooth 607 after being docked with the locking tooth 607, forming a firm fixation. The design of the return spring 614 ensures that the locking claw 613 can return to its original position after being subjected to an external force and connect with the locking tooth 607, further improving the reliability of the anti-falling device body 7. Even when the locking mechanism fails, the return spring 614 can ensure the normal function of the locking claw 613, avoiding potential safety hazards caused by the loosening of the anti-falling device body 7. Moreover, the traditional anti-falling device body 7 usually needs to be disassembled or installed from both ends of the guide rail, which is very inconvenient for operations at high altitudes or in complex environments. However, the anti-falling device body 7 of the present invention allows the user to easily disassemble it when needed through a telescopic structure design and can be quickly installed at other positions.

[0042] Example 2, according to Figures 1 - 4 As shown, the cleaning mechanism 4 includes a support arm 406, a fixing plate 405, a pressing spring 404, and a cleaning brush 402. The outer side of the fixing plate 405 is fixedly connected to the support arm 406. The inner side of the fixing plate 405 is fixedly connected to the pressing spring 404. One end of the pressing spring 404 is fixedly connected to the cleaning brush 402. One side of the first clamping plate 2 and one side of the second clamping plate 3 are both fixedly connected to a connecting arm 401. The two connecting arms 401 are respectively fixedly connected to each support arm 406. The outer side of each cleaning brush 402 is fixedly connected to a scraping plate 403. The inner side of each cleaning brush 402 is attached to the outer wall of the iron tower guide rail 1. One end of each scraping plate 403 is attached to the outer wall of the iron tower guide rail 1.

[0043] The effects achieved by the entire Embodiment 2 are as follows: When the anti-falling device body 7 moves, the two connecting arms 401 drive the two support arms 406 to move respectively. During the movement of the support arms 406, the inner pressure spring 404 will push the cleaning brush 402 to closely fit the inner wall of the iron tower guide rail 1 for effective cleaning. This design can not only remove the dust and dirt on the inner wall of the iron tower guide rail 1, but also avoid affecting the normal use of the anti-falling device body 7 due to insufficient friction. The design of the cleaning brush 402 also includes driving the scraping plate 403 to clean the rust and impurities on the outer wall of the iron tower guide rail 1. This function can effectively remove the possible rust and impurities on the surface of the guide rail, preventing them from having an adverse impact on the performance and safety of the anti-falling device body 7, thereby reducing the safety hazards caused by rust or dirt accumulation. The automatic cleaning function can keep the iron tower guide rail 1 clean, ensuring the stability and smoothness of the anti-falling device body 7 during long-term use; Secondly, the dual cleaning effects of the cleaning brush 402 and the scraping plate 403 effectively eliminate rust, impurities and dirt, avoid insufficient friction caused by problems on the surface of the guide rail, improve the contact stability between the anti-falling device body 7 and the iron tower guide rail 1, and thus enhance the safety.

[0044] It should be noted that: The impurities on the surface of the iron tower guide rail 1 may cause unstable contact between the anti-falling device body 7 and the guide rail. Especially in the high-altitude operation environment, any minor instability will greatly increase the risk of falling. The anti-falling device body 7 must be firmly fixed on the iron tower guide rail 1 to prevent accidents during the operation of the user. The presence of dust and impurities will increase the probability of the anti-falling device body 7 sliding or falling off, and may even cause the equipment to fail in severe cases. The impurities on the outer wall of the iron tower guide rail 1, especially moisture and rust, may cause corrosion and wear on the surface of the iron tower guide rail 1. Long-term corrosion and wear will not only affect the structural strength of the guide rail itself, but may also affect the contact surface between the anti-falling device body 7 and the iron tower guide rail 1, resulting in uneven contact and further reducing the fixing effect of the anti-falling device body 7. This will accelerate the aging and damage of the equipment and reduce its service life.

[0045] The working principle of the entire device is as follows: First, during the installation process, the user can place the first clamping plate 2 and the second clamping plate 3 on both sides of the iron tower guide rail 1 respectively. Subsequently, by rotating the transmission handle 609, the transmission wheel 608 is driven to rotate, which in turn drives the rotation of the second telescopic rod 620, and drives the rotation of the transmission bevel gear II 624 through the transmission shaft 621. The transmission bevel gear II 624 meshes with the transmission bevel gear I 623, pushing the first vertical wheel to rotate. The transmission bevel gear I 623 drives the screw rod 617 to rotate, driving the threaded part 616 to move, so that the first clamping plate 2 and the second clamping plate 3 approach each other, and the guide wheel 9 closely adheres to the outer wall of the iron tower guide rail 1. After that, the user adjusts the transmission wheel 608 to move the second telescopic rod 620 and inserts the locking rod 619 to lock the transmission wheel 608, ensuring the stable installation of the anti-falling device body 7. If the user accidentally falls, the connecting piece will drive the pre-compressor 12 to descend, the trigger is triggered, driving the second transmission gear 11 to rotate. Through the elastic action of the spring rod 603, the rack 604 meshes with and rotates with the second transmission gear 11, driving the two clamping eccentric wheels 8 to clamp the iron tower guide rail 1 to achieve locking, ensuring the reliable fixation of the anti-falling device body 7. The anti-falling device body 7 of the present invention adopts a telescopic structural design, enabling the anti-falling device body 7 to be easily disassembled from the guide rail when needed and quickly installed in other positions. This design not only saves the time for installation and disassembly but also improves work efficiency, especially suitable for high-altitude operations and iron tower maintenance sites where the position needs to be frequently changed. In addition, the telescopic design enables the anti-falling device body 7 to adapt to iron tower guide rails 1 of different sizes and shapes, and can be flexibly applied in both narrow and spacious working spaces to meet various requirements. To enhance the safety of the anti-falling device body 7, the present invention also designs a double insurance mechanism. During the installation process, the locking teeth 607 inside the locking plate 606 exert a squeezing force on the locking claw 613. When the positions of the locking teeth 607 and the locking claw 613 are docked, the reset spring 614 drives the locking claw 613 to rise, ensuring that the locking claw 613 inserts into the inner wall of the locking teeth 607, thus effectively preventing the anti-falling device body 7 from loosening or being unstable during use and providing additional safety guarantees. Even when the locking mechanism fails, the reset spring 614 can still ensure that the locking claw 613 successfully inserts into the locking teeth 607, further enhancing the reliability of the system. In addition, the present invention also sets up a cleaning mechanism 4 to ensure that the iron tower guide rail 1 remains clean during long-term use, preventing the stability of the anti-falling device body 7 from being affected by dirt, rust or impurities. When the anti-falling device body 7 moves along the iron tower guide rail 1, the two connecting arms 401 drive the two support arms 406 to move, and the pressure spring 404 pushes the cleaning brush 402 to closely adhere to the inner wall of the iron tower guide rail 1, effectively removing the dust and dirt on the inner wall of the guide rail and avoiding insufficient friction from affecting the normal use of the anti-falling device body 7. The cleaning brush 402 also drives the scraping plate 403 to clean the rust and impurities on the outer wall of the guide rail, preventing the accumulation of rust or impurities from affecting the contact stability between the iron tower guide rail 1 and the anti-falling device body 7 and reducing potential safety hazards.To ensure the long-term stability and smooth operation of the anti-falling device body 7. In summary, through its innovative installation mechanism 6, double-layer insurance mechanism, telescopic structure and efficient cleaning system, the anti-falling device body 7 of the present invention significantly improves the safety, stability, adaptability and operation convenience of the anti-falling device body 7, and is particularly suitable for working occasions with extremely high safety requirements such as high-altitude operations and tower maintenance.
