Description

Technical Field

[0001] This utility model relates to the field of tower fall prevention safety technology, and more specifically, to a steel guide rail device for tower fall prevention. Background Technology

[0002] With the continuous development of infrastructure such as communications and power, tower-type aerial work platforms are widely used in complex environments such as cities and mountains. To ensure the personal safety of workers during high-altitude operations, fall arrest systems are usually installed to prevent accidental falls. Existing fall arrest systems mostly use flexible safety ropes with sliding buckles, which provide a certain degree of protection, but are prone to slippage, jamming, or failure under high-frequency use or complex weather conditions, posing safety hazards.

[0003] However, traditional flexible fall arrestors often suffer from limited structural strength and poor connection stability, leading to slippage with body movement and delayed braking. While some rigid guide rail devices possess strong support capabilities, they exhibit issues such as poor guidance, inaccurate coordination, and complex braking structures during ascent or descent, resulting in inconvenient operation, low efficiency, and an inability to meet the high reliability and safety requirements of actual high-altitude operations. Furthermore, existing devices generally lack intelligent auxiliary control for fall arrest actions, failing to respond quickly and automatically lock in emergency situations.

[0004] Therefore, in order to overcome the above problems, this application provides a steel tower anti-fall rigid guide rail device, which combines steel slide rail, ratchet adjustment structure and fastening locking mechanism to improve the guiding stability and braking response capability of the device during vertical movement, especially in the event of sudden slippage, it can achieve rapid and effective fall protection. Utility Model Content

[0005] In view of this, this utility model proposes a rigid guide rail device for tower fall protection to address the shortcomings of existing flexible or rigid fall protection devices in terms of structural strength, guiding accuracy, braking response and intelligent control, which makes it difficult to meet the safety and reliability requirements of high-altitude operations.

[0006] This utility model provides a steel tower fall-prevention rigid guide rail device, comprising: a steel slide rail, an installation mechanism and a fall-prevention box on the steel slide rail, a T-shaped groove on the front side of the steel slide rail, a toothed plate on the T-shaped groove, a sliding groove on the fall-prevention box, the steel slide rail passing through the sliding groove, an adjustment groove on one side of the sliding groove, a ratchet on the adjustment groove, bearing seats between the two ends of the ratchet and the adjustment groove, a fastening box and a safety hook on the fall-prevention box, a fastening hole on the fastening box, a fastening post on the fastening hole, a hinge at one end of the fastening post, a stop pawl on the hinge, a fastening groove on the fastening hole, a fastening plate between the fastening groove and the fastening post, and an elastic support mechanism and an electric pushing mechanism between the fastening plate and the fastening groove.

[0007] Furthermore, the elastic support mechanism includes a compression spring, which is mounted on the inner wall of the fastening groove and connected at one end to the fastening plate.

[0008] Furthermore, the electric actuation mechanism includes an electric telescopic rod and a push block. The push block is located in the fastening groove and abuts against one side of the fastening plate. The electric telescopic rod is installed on one side of the fastening box. The output end of the electric telescopic rod extends into the fastening groove and connects to the push block. The electric telescopic rod is provided with a control interface.

[0009] Furthermore, the compression springs are provided in two symmetrical arrangements.

[0010] Furthermore, the mounting mechanism includes mounting holes, which are formed on the rear side of the steel slide rail and are arranged in a plurality of arrays.

[0011] Furthermore, the adjusting groove is provided with a limiting block, which extends to the side of the T-shaped groove, and there are two limiting blocks arranged symmetrically.

[0012] Furthermore, guide grooves are provided on both sides of the steel slide rail, and guide blocks are provided on the guide grooves and connected to the inner wall of the slide grooves.

[0013] Furthermore, an adjusting screw hole is provided at the end of the ratchet wheel shaft, and a locking bolt is screwed into the adjusting screw hole, with the end of the locking bolt pressing against the side wall of the bearing seat.

[0014] Furthermore, the control interface is externally covered with a waterproof sealing cover, which is connected to the outer wall of the fastening box based on a snap-fit ​​structure.

[0015] Compared with existing technologies, the advantages of this invention are as follows: By setting a T-shaped groove and toothed plate structure on the front side of the steel slide rail, the fall arrestor box forms a reliable guiding and meshing engagement with the slide rail during sliding along the guide rail, greatly improving the operational stability and anti-shaking ability of the device, ensuring the smooth vertical movement of personnel working at heights, and avoiding safety risks caused by slippage and deviation. In addition, the toothed plate design also provides a mechanical engagement point for the fall arrest action, making braking more reliable and the response faster. The fall arrestor box body structure is equipped with a slide groove and an adjustment groove. The steel slide rail passes through the slide groove to achieve overall sliding movement, and an adjustment groove and ratchet assembly are provided on one side of the slide groove, which, together with the bearing seat, form an adjustable buffer and fall arrest structure. When the user moves up and down normally, the device can slide smoothly; but once an unexpected change in acceleration occurs, such as a rapid fall, the ratchet mechanism will immediately engage the toothed plate to achieve a locking function, thereby achieving efficient physical fall arrest and ensuring the safety of personnel. In addition, the fall arrestor box is equipped with a fastening box, which integrates multiple mechanical components such as fastening holes, fastening posts, stop claws, and fastening plates. One end of the fastening post is linked to the stop claw via a hinge, enabling quick locking and releasing. The fastening slot and the fastening post are connected by a fastening plate, and an elastic support mechanism and an electric actuation mechanism are provided. This allows the structure to quickly close and open under electric drive when needed, effectively improving operational efficiency and safety, and allowing users to flexibly adjust the device's operating mode in different situations. Finally, the elastic support mechanism not only improves shock absorption performance during the stopping process but also buffers impact forces, preventing structural damage caused by hard locking; the electric actuation mechanism enables remote or automatic control, enhancing the device's adaptability to intelligent, high-frequency operating environments, making it particularly suitable for high-altitude applications such as power maintenance and communication installation that require frequent up-and-down operations.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] like Figures 1-5As shown in some embodiments of this application, a steel tower fall arresting rigid guide rail device includes: a steel slide rail 1, an installation mechanism and a fall arresting box 2 on the steel slide rail 1, a T-shaped groove on the front side of the steel slide rail 1, a toothed plate 3 on the T-shaped groove, a sliding groove on the fall arresting box 2, the steel slide rail 1 passing through the sliding groove, an adjustment groove on one side of the sliding groove, a ratchet 4 on the adjustment groove, bearing seats 5 between the two ends of the ratchet 4 and the adjustment groove, a fastening box 6 and a safety hook 18 on the fall arresting box 2, a fastening hole on the fastening box 6, a fastening post 7 on the fastening hole, a hinge at one end of the fastening post 7, a stop claw 8 on the hinge, a fastening groove on the fastening hole, a fastening plate 9 between the fastening groove and the fastening post 7, and an elastic support mechanism and an electric pushing mechanism between the fastening plate 9 and the fastening groove.

[0027] Understandably, with the steel slide rail 1 as the core supporting component, a T-shaped groove and a toothed plate 3 are provided on the front side of the slide rail. The T-shaped groove structure can effectively guide the linear sliding of the fall arrestor box 2, making its vertical operation more stable. The toothed plate 3 provides the meshing surface with the ratchet 4 device and is an important supporting component for the device to achieve mechanical fall protection. When the fall arrestor box 2 moves up and down along the slide rail, the toothed plate 3 can cooperate with the ratchet 4 inside the fall arrestor device to move. In the event of a sudden fall, the ratchet 4 instantly engages with the toothed groove of the toothed plate 3, forming a physical brake to prevent the user from falling further and effectively protect the safety of personnel. Secondly, the fall arrestor box 2 is provided with a sliding groove and an adjustment groove. The sliding groove provides a guide track for the movement of the slide rail, maintaining the stability of the fall arrestor device. The adjustment groove is equipped with a ratchet 4 and a bearing seat 5. The ratchet 4 can slide freely during normal up and down movement, and in the event of a sudden fall, it quickly engages with the toothed plate 3 through inertia to achieve self-locking fall protection. The bearing housing 5 not only ensures the flexible rotation of the ratchet 4 but also absorbs a certain amount of impact load, enhancing the device's durability and impact resistance. Furthermore, the internal structure of the fastening box 6 further strengthens its safety protection capabilities. Its fastening holes, fastening posts 7, hinges, and stop pawls 8 form a mechanical linkage locking structure. When the fall arrestor needs manual fixing or emergency locking, this mechanism can quickly achieve physical clamping. The fastening post 7 is connected to the stop pawl 8 via a hinge, and can actively engage or release at specific angles, facilitating user operation and possessing a certain degree of self-resetting capability. Finally, a fastening plate 9 is provided between the fastening groove and the fastening post 7. The fastening plate 9 not only provides support and force transmission but also provides a buffering function through an elastic support mechanism, acting as a buffer and absorbing energy during braking or emergency locking to prevent structural damage caused by rigid contact. The matching electric drive mechanism provides intelligent control capabilities for the device, allowing remote triggering of fastening actions as needed to achieve automatic locking, resetting, and releasing functions, providing a more convenient, safe, and intelligent operating experience for high-altitude operations.

[0028] Specifically, the elastic support mechanism includes a compression spring 10, which is mounted on the inner wall of the fastening groove and connected at one end to the fastening plate 9.

[0029] Specifically, there are two compression springs 10 arranged symmetrically.

[0030] Understandably, by installing a compression spring 10 on the inner wall of the fastening groove, with one end of the spring connected to the fastening plate 9, an elastic support mechanism is formed. During braking or locking of the device, when the fastening plate 9 is subjected to external force, the compression spring 10 can store energy under compression, achieving a buffering and energy absorption effect, reducing the direct impact load on the structure, and avoiding deformation or damage caused by rigid contact. At the same time, the spring can automatically rebound after the external force is released, pushing the fastening plate 9 to reset, ensuring that the device has a certain self-recovery capability and continuous buffering function, thereby improving the safety and service life of the entire fall protection system.

[0031] Specifically, the electric drive mechanism includes an electric telescopic rod 11 and a push block 12. The push block 12 is located in the fastening groove and abuts against one side of the fastening plate 9. The electric telescopic rod 11 is installed on one side of the fastening box 6. The output end of the electric telescopic rod 11 extends into the fastening groove and connects to the push block 12. The electric telescopic rod 11 is provided with a control interface 13.

[0032] It is understandable that by using the electric telescopic rod 11 as the actuating element, combined with the push block 12 structure, automatic driving and control of the fastening plate 9 can be achieved. Specifically, the electric telescopic rod 11 is installed on one side of the fastening box 6, and its output end extends into the fastening groove and connects to the push block 12, which rests against one side of the fastening plate 9. When the electric telescopic rod 11 extends or retracts, the push block 12 moves accordingly, thereby pushing or releasing the fastening plate 9, realizing the opening and closing control of the fastening structure. This structure is equipped with a control interface 13, which can be connected to an external control system to realize remote operation or intelligent linkage control. In applications such as emergency protection or timed release, it has the advantages of fast response, precise control, and high degree of automation, significantly improving the safety and intelligence level of the fall arrestor.

[0033] Specifically, the mounting mechanism includes mounting holes 14, which are provided on the rear side of the steel slide rail 1 and are arranged in an array.

[0034] Understandably, by setting multiple arrayed mounting holes 14 on the rear side of the steel slide rail 1 to form a mounting mechanism, the slide rail can be stably installed and flexibly positioned on different support structures. The arrayed hole design allows the slide rail to be fixed at multiple points according to actual usage needs, enhancing its overall load-bearing capacity and structural stability, and effectively preventing the slide rail from shaking or shifting during high-frequency use or under stress. At the same time, this structure also facilitates the rapid installation and disassembly of the device on different types of iron towers or working platforms, improving the device's versatility and engineering adaptability.

[0035] Specifically, the adjustment groove is provided with a limiting block 15, which extends to the side of the T-shaped groove. There are two limiting blocks 15 arranged symmetrically.

[0036] Understandably, two symmetrically distributed limiting blocks 15 are installed on the adjusting groove, extending to the sides of the T-shaped groove, forming a physical restriction structure on the movement range of the sliding component. The limiting blocks 15 effectively control the movement of the fall arrestor box 2 on the slide rail, preventing it from deviating from the set track or sliding off the guide rail, thus avoiding danger caused by operational instability or component failure. By symmetrically setting two limiting blocks 15, force balance is maintained, improving structural stability and guiding accuracy, thereby enhancing the safety and reliability of the entire fall arrestor device during operation.

[0037] Specifically, the steel slide rail 1 has guide grooves 16 on both sides, and guide blocks 17 are provided on the guide grooves 16 and connected to the inner wall of the slide groove.

[0038] Understandably, by setting guide grooves 16 on both sides of the steel slide rail 1, and installing guide blocks 17 within the guide grooves 16, with the guide blocks 17 connected to the inner wall of the slide groove of the fall arrestor box 2, a stable guiding and mating structure is formed. This design ensures that the fall arrestor box 2 remains stably centered during its up-and-down sliding along the slide rail, preventing deviation, swaying, or jamming, and significantly improving sliding accuracy and smooth operation. Simultaneously, the sliding action of the guide blocks 17 within the guide grooves 16 enhances the overall structure's anti-sway performance and mechanical coupling stability, providing more reliable guiding support for the fall arrestor braking action, thereby improving the safety and service life of the entire protective device.

[0039] Specifically, an adjusting screw hole is provided at the end of the ratchet 4 shaft, and a locking bolt is screwed into the adjusting screw hole, with the end of the locking bolt pressing against the side wall of the bearing seat 5.

[0040] Understandably, by setting an adjusting screw hole at the end of the ratchet 4 axle and screwing a locking bolt into the screw hole, the bolt end is pressed against the side wall of the bearing seat 5, thus achieving precise adjustment and fixation of the gap and position between the ratchet 4 axle and the bearing seat 5. This structure effectively ensures the rotational flexibility and stability of the ratchet 4, prevents the axle from shifting or vibrating due to loosening, improves the mechanical stability and reliability of the device, and thus ensures that the anti-fall mechanism can accurately and smoothly complete the meshing and braking actions of the ratchet 4 and the toothed plate 3 during operation.

[0041] Specifically, the control interface 13 is externally covered with a waterproof sealing cover, which is connected to the outer wall of the fastening box 6 based on a snap-fit ​​structure.

[0042] Understandably, by installing a waterproof sealing cover on the outside of the control interface 13 and using a snap-fit ​​structure to fix the sealing cover to the outer wall of the fastening box 6, effective protection of the control interface 13 can be achieved. This design can prevent external environmental factors such as moisture and dust from entering the control interface 13, ensuring the safety and stability of electrical connections, avoiding faults such as short circuits and corrosion caused by moisture or pollution, thereby improving the durability and reliability of the device and ensuring the long-term stable operation of the fall protection system in various complex environments.

[0043] It is understood that the steel tower fall arrestor rigid guide rail device in the above embodiments uses a steel slide rail 1 as the core guiding and supporting component. The front side of the slide rail is provided with a toothed T-shaped groove, and the fall arrestor box 2 is fitted onto the slide rail through the groove, allowing the fall arrestor box 2 to slide smoothly up and down along the slide rail. When the user moves up and down on the tower or high-altitude work platform, the fall arrestor box 2 slides accordingly. The toothed plate 3 and the ratchet 4 inside the fall arrestor box 2 maintain free engagement, allowing normal movement and adjustment. In the event of an emergency fall or uncontrolled descent, the ratchet 4 quickly engages the toothed groove of the toothed plate 3 on the slide rail due to inertia, achieving instantaneous mechanical locking and preventing the fall arrestor box 2 from continuing to slide down, thereby ensuring the safety of the workers. The bearing seats 5 at both ends of the ratchet 4 ensure the flexibility and durability of the ratchet 4's rotation, effectively withstand impact loads, and ensure the reliability and response speed of the braking action. In addition, the fastening mechanism inside the fastening box 6 achieves mechanical locking and fixing of the fall arrestor box 2 through structures such as fastening posts 7, hinges, and stop claws 8. In conjunction with an elastic support mechanism (such as compression spring 10), impact energy is absorbed during the tightening process, reducing mechanical damage to the device. The electric drive mechanism, via electric telescopic rod 11, drives push block 12 to automatically drive and control the fastening plate 9. Tightening and releasing operations can be completed remotely or automatically via control interface 13, improving the intelligence and ease of operation of the fall arrestor. Multiple arrayed mounting holes 14 in the mounting mechanism ensure a stable connection between the slide rail and the support structure, improving the overall stability and anti-shaking capability. Symmetrical limit blocks 15 on the adjusting groove limit the movement range of the fall arrestor box 2, preventing safety hazards caused by excessive displacement. The guide grooves 16 and guide blocks 17 on both sides of the slide rail effectively maintain the running direction and position of the fall arrestor box 2, preventing deviation and jamming, and ensuring smooth and stable operation. Finally, the locking bolt precisely adjusts the position of the ratchet 4 shaft through the adjusting screw hole, ensuring the meshing quality and braking effect of the ratchet 4 and the toothed plate 3. The control interface 13 is equipped with a waterproof sealing cover to protect the electrical components from environmental factors, improving the durability and operational reliability of the device.

[0044] Specifically, during installation with the tower, the steel guide rail device for tower fall protection uses a steel slide rail 1 as the core load-bearing and support structure. Relying on multiple array-type mounting holes 14 pre-set on the rear side of the slide rail, it can flexibly adapt to different tower structures. Installers can select appropriate mounting hole 14 positions according to the size, shape, and load-bearing requirements of the tower column, and securely fix the slide rail to the tower support surface using bolts and other fasteners. The multi-point array-type hole design not only improves installation freedom but also significantly enhances the uniformity of force distribution and anti-sway capability of the slide rail during actual application, ensuring the stability and reliability of the entire fall protection system in high-altitude working environments. After the slide rail is fixed, the fall protection box 2 can slide freely up and down along the steel slide rail 1, achieving follow-up protection for the operator. The fall protection box 2 precisely matches the slide rail through a sliding groove, and with the help of the guide grooves 16 and guide blocks 17 on both sides of the slide rail, it effectively avoids deviation, swaying, or jamming during movement, maintaining smooth and linear linear movement. The T-slot and toothed plate 3 on the front side of the slide rail provide basic support for the fall arrest braking system. If a worker slips and falls, the ratchet 4 inside the fall arrest box 2 can instantly engage with the toothed plate 3, achieving mechanical locking and preventing further falls, thus ensuring personnel safety. When temporary fixation or emergency locking is required, the linkage locking mechanism consisting of the fastening box 6, fastening column 7, hinge, and stop pawl 8 inside the fall arrest box 2 can be manually or automatically triggered to firmly fix the fall arrest box 2 to a certain position on the slide rail, preventing accidental slippage. At this time, the fastening plate 9 installed in the fastening groove, under the control of the electric push mechanism, works with the elastic support mechanism to achieve precise locking and buffer energy absorption, effectively improving the stability and safety during braking. Through the control interface 13, users can also achieve remote control, automatically completing protective actions and improving the intelligence level of installation and use. Furthermore, the electric push mechanism and electrical control part of the fall arrest system are effectively isolated from the tower environment through a waterproof sealing cover, possessing excellent dustproof, waterproof, and corrosion-resistant capabilities. It can cope with the harsh environments commonly encountered at tower operation sites, such as wind, rain, dust, and corrosion, improving the overall stability and durability of the equipment.

[0045] The steel tower fall arrestor rigid guide rail device described in the above embodiments, by setting a T-shaped groove and toothed plate 3 structure on the front side of the steel slide rail 1, allows the fall arrestor box 2 to form a reliable guiding and meshing engagement with the slide rail during sliding along the guide rail, greatly improving the device's operational stability and anti-sway capability, ensuring the smooth vertical movement of personnel working at heights, and avoiding safety risks caused by slippage and deflection. Furthermore, the design of the toothed plate 3 provides a mechanical engagement point for the fall arrest action, making braking more reliable and the response faster. The fall arrestor box 2 body structure is provided with a slide groove and an adjustment groove. The steel slide rail 1 passes through the slide groove to achieve overall sliding movement, and an adjustment groove and ratchet 4 assembly are provided on one side of the slide groove, forming an adjustable buffer and fall arrest structure in conjunction with the bearing seat 5. When the user moves up and down normally, the device can slide smoothly; however, in the event of an unexpected change in acceleration, such as a rapid fall, the ratchet 4 mechanism will immediately engage the toothed plate 3 to achieve a locking function, thereby achieving efficient physical fall arrest and ensuring personnel safety. In addition, the fall arrestor box 2 is equipped with a fastening box 6, which integrates multiple mechanical components such as fastening holes, fastening posts 7, stop claws 8, and fastening plates 9. One end of the fastening post 7 is linked to the stop claw 8 via a hinge, enabling quick locking and releasing. The fastening slot and the fastening post 7 are connected by the fastening plate 9, and an elastic support mechanism and an electric drive mechanism are provided. This allows the structure to quickly close and open under electric drive when needed, effectively improving operational efficiency and safety, and allowing users to flexibly adjust the device's working mode in different situations. Finally, the elastic support mechanism not only improves shock absorption performance during the stopping process but also buffers impact forces, preventing structural damage caused by hard locking. The electric drive mechanism enables remote or automatic control, enhancing the device's adaptability in intelligent, high-frequency operating environments, making it particularly suitable for high-altitude applications such as power maintenance and communication installation that require frequent up-and-down operations.
