Description
Technical Field
[0001] This invention relates to the field of power technology, and in particular to a modular anti-fall guide rail device that adapts to the profile of a steel tower. Background Technology
[0002] With the continuous development of infrastructure construction such as power and communications, high-altitude operations such as daily inspections, maintenance, and repairs of iron towers are becoming increasingly frequent. When performing high-altitude operations, in order to ensure the personal safety of workers, it is usually necessary to wear fall protection safety equipment and cooperate with fall protection guide rail devices installed on the iron tower for climbing and moving.
[0003] However, existing fall arrestor rail devices still have the following shortcomings in practical applications: Fixed guide rail positions limit the working range and restrict flexibility: Most existing fall arrestor rails are bolted directly to one side of the tower, making lateral adjustment impossible based on the tower's profile or the worker's specific work position. This results in extremely limited protection for workers moving laterally above the tower. Furthermore, the connection structure between the existing safety rope and the guide rail slider is often simplistic, typically rigidly fixed or only supporting unidirectional rotation. This lack of flexibility hinders workers' ability to work at multiple angles, potentially restricting their movement.
[0004] The lack of an automatic lubrication mechanism leads to severe wear and tear over long-term use: The guide rails and sliders are constantly exposed to harsh outdoor environments, generating significant friction during frequent up-and-down sliding. Existing devices typically lack automatic lubrication, requiring regular manual maintenance at height. This is not only time-consuming and labor-intensive, but inadequate lubrication can easily cause accelerated wear or even jamming of the slider within the guide rails, affecting the smoothness of lifting and lowering.
[0005] The fall arrestor system is simplistic and lacks rope anti-jamming and multi-layered buffer protection designs: During normal lifting and lowering, the existing guide rail fall arrestor system is prone to steel wire rope slack that accumulates inside the guide rail, causing the slider to jam as it rises. Secondly, when a worker accidentally falls, existing fall arrestors rely on simple mechanical gears for locking, lacking a smooth braking mechanism similar to a car brake disc, resulting in a large instantaneous impact force during braking. More critically, if the main protective structure fails, the slider will slide directly to the bottom of the guide rail, often resulting in a rigid collision with the bottom of the rail. The enormous reaction force can easily cause severe secondary injuries to the falling worker.
[0006] Therefore, there is an urgent need for a modular anti-fall guide rail device that adapts to the profile of the iron tower, in order to solve the problems of limited range of motion, lack of automatic lubrication, and incomplete anti-fall braking and buffer protection in the existing technology. Summary of the Invention
[0007] To achieve the above objectives, the present invention employs the following technical solution: a modular anti-fall guide rail device with adaptive tower profile, comprising: a guide rail body and two mounting plates. The guide rail body is slidably connected to the interior of the two mounting plates. Multiple locking holes are provided on the outer surfaces of the two mounting plates. Two second fixing blocks are fixedly installed on the outer surface of the guide rail body. Two first fixing blocks are fixedly installed on the outer surface of the guide rail body. Locking rods are movably embedded inside each of the two second fixing blocks. Each locking rod is movably embedded inside two of the locking holes. Limiting round blocks are fixedly installed at the top of each of the two limiting round blocks. Springs are fixedly installed on one side of each of the two limiting round blocks. One end of each of the two springs is fixedly installed on one side of each of the two first fixing blocks. Linkage rods for linkage are fixedly installed on opposite sides of the two limiting round blocks. A slider is slidably connected inside the guide rail body. A connecting block is fixedly installed on one side of the slider. A first rotating rod is movably embedded inside the connecting block. A U-shaped block is movably fitted on the outer surface of the first rotating rod. A second rotating rod is movably embedded inside the U-shaped block. A movable block is movably fitted on the outer surface of the second rotating rod.
[0008] The technical effect of adopting the above-mentioned further solution is as follows: First, the worker installs the mounting plate on top of the tower using screws and nuts. When needed, the worker's safety rope is tied to the top of the movable block. The movable block can rotate vertically around the U-shaped block via the second rotating rod, and the U-shaped block can rotate horizontally around the connecting block via the first rotating rod. After the rope is fixed above the movable block, both horizontal and vertical movement can be achieved, improving the flexibility of the movable block. When the worker needs to move horizontally above the tower, pulling the linkage rod moves the limiting blocks on the upper and lower parts of the guide rail body in the opposite direction to the mounting plate. At this time, the limiting blocks can cause the locking rod to disengage from the inside of the locking hole. After disengagement, the guide rail body can move horizontally inside the mounting plate. This movement increases the protection range and working distance of the guide rail body. Under the limiting action of the two springs, the limiting blocks adhere to the outer surface of the second fixed block. At this time, the locking rod is locked inside the locking hole, limiting the guide rail body and preventing it from sliding easily when adjusted to the required position within the mounting plate.
[0009] In a preferred embodiment, an extrusion cylinder is fixedly installed on the outer surface of the guide rail body near its top. An extrusion block is slidably connected to the inner wall of the extrusion cylinder. A spring is fixedly installed on the top of the extrusion block. A push rod is fixedly installed on the outer surface of the extrusion block away from the spring. The push rod is movably embedded inside the extrusion cylinder. A rectangular strip is fixedly installed at the bottom end of the push rod. An oil supply pipe is fixedly installed on the side of the extrusion cylinder near its top. One end of the oil supply pipe extends into the interior of the guide rail body.
[0010] The technical effect of adopting the above-mentioned further solution is as follows: when the slider moves to the top of the guide rail body, the connecting block contacts the rectangular bar, thereby pushing the push rod to move upward. The push rod pushes the extrusion block to slide on the inner wall of the extrusion cylinder, which can squeeze the internal lubricating oil to the oil supply pipe, and then squeeze it to the inner wall of the guide rail body through the oil supply pipe, reducing the wear of the slider inside the guide rail body. Under the limit of the spring three, the extrusion block returns to its original position for the next extrusion.
[0011] In a preferred embodiment, a take-up roller is rotatably mounted on the top of the guide rail body, and a steel wire rope is sleeved on the outer surface of the take-up roller. One end of the steel wire rope is fixedly connected to the top of the slider, and a connecting frame is fixedly mounted on the top of the guide rail body.
[0012] The technical effect of adopting the above-mentioned further solution is that when the slider slides upward inside the guide rail body, the take-up roller can take up the limiting block. When the slider moves downward, the take-up roller can rotate in the opposite direction. The torsion spring can pull the slider to the highest point inside the guide rail body without being subjected to any external force. The torsion spring can prevent the wire rope from contacting the slider inside the guide rail body when the slider rises, causing the slider to jam.
[0013] In a preferred embodiment, multiple limiting rods are fixedly installed on both the upper and lower sides of the connecting frame, a motor is fixedly installed on the top of the connecting frame, a gear is fixedly installed on the output end of the motor, and a first rack is meshed with the outer surface of the gear.
[0014] The technical effect of adopting the above-mentioned further solution is as follows: When a worker accidentally falls, the slider slides rapidly downward inside the guide rail body. At this time, the motor rotates rapidly, and after rotation, it drives the first rack and second rack that are meshed on their surfaces to move. The limit rod sets a limit to limit them. After moving, it drives the second friction semicircular block and the first friction semicircular block to move towards the rotating disk. The first friction semicircular block and the second friction semicircular block clamp the outer surface of the rotating disk, which can reduce the rotation speed of the rotating disk until it stops rotating, similar to the brake disc of a car.
[0015] In a preferred embodiment, the outer surface of the gear is meshed with a second rack, and both the first rack and the second rack are slidably connected to the outer surfaces of a plurality of limiting rods. A first friction semicircular block is fixedly installed on the outer surface of the first rack, and a second friction semicircular block is fixedly installed on the outer surface of the second rack.
[0016] The technical effect of adopting the above-mentioned further solution is that when the rotating disk is locked by the first friction semicircular block and the second friction semicircular block, the take-up roller will stop rotating, and the wire rope will instantly pull the slider to stop rotating inside the guide rail body.
[0017] In a preferred embodiment, a rotating disk is fixedly installed on one side of the take-up roller, the first friction semicircular block and the second friction semicircular block are respectively located on the upper and lower sides of the rotating disk, a plurality of springs are fixedly installed at the bottom of the guide rail body, two limiting telescopic rods are fixedly installed at the bottom of the guide rail body, elastic plates are fixedly installed on the top of the plurality of springs and the two limiting telescopic rods, and a torsion spring is provided inside the take-up roller.
[0018] The technical effect of adopting the above-mentioned further solution is: a second layer of protection. When the slider continues to fall inside the guide rail body, the slider falls to the bottom of the guide rail body and contacts the upper surface of the elastic plate. The elastic plate can be buffered by the large torsion spring and limited by the limiting telescopic rod. This can prevent the slider from contacting the bottom of the inner wall of the guide rail body, which would cause large vibrations and reduce the injury to the staff.
[0019] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this embodiment of the invention, the worker first installs the mounting plate on top of the tower using screws and nuts. When needed, the worker's safety rope is tied to the top of the movable block. The movable block can rotate vertically around the U-shaped block via the second rotating rod, and the U-shaped block can rotate horizontally around the connecting block via the first rotating rod. After the rope is fixed above the movable block, horizontal and vertical movement can be achieved, improving the flexibility of the movable block. When the worker needs to move horizontally above the tower, the limit blocks on the upper and lower parts of the guide rail body are moved in the opposite direction to the mounting plate by pulling the linkage rod. At this time, the limit blocks can cause the locking rod to disengage from the inside of the locking hole. After disengagement, the guide rail body can move horizontally inside the mounting plate. After movement, the protection range of the guide rail body during use can be increased, and the working distance of the guide rail body can be increased. Under the limiting action of the two springs, the limit blocks are made to fit against the outer surface of the second fixed block. At this time, the locking rod is locked inside the locking hole, which can limit the guide rail body and prevent the guide rail body from sliding inside the mounting plate. When adjusted to the required position, it will not easily slide.
[0020] 2. In this embodiment of the invention, when the slider slides upward inside the guide rail body, the take-up roller can wind up the limiting block. When the slider moves downward, the take-up roller can rotate in the opposite direction. The torsion spring allows the take-up roller to pull the slider to the highest point inside the guide rail body without any external force. The torsion spring prevents the wire rope from contacting the slider inside the guide rail body when the slider rises, causing the slider to jam. A second layer of protection is also provided. When the slider continues to fall inside the guide rail body, it falls to the bottom of the guide rail body and contacts the upper surface of the elastic plate. The large torsion spring can buffer the elastic plate, and the limiting telescopic rod limits the elastic plate, preventing the slider from contacting the bottom of the inner wall of the guide rail body, which would cause excessive vibration and reduce injury to workers.
[0021] 3. In this embodiment of the invention, when the slider moves to the top of the guide rail body, the connecting block contacts the rectangular bar, thereby pushing the push rod to move upward. The push rod pushes the extrusion block to slide on the inner wall of the extrusion cylinder, which can squeeze the internal lubricating oil to the oil supply pipe, and then squeeze it to the inner wall of the guide rail body through the oil supply pipe, reducing the wear of the slider inside the guide rail body. Under the limit of the spring three, the extrusion block returns to its original position for the next extrusion. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figures 1 to 7 This embodiment provides a technical solution: a modular anti-fall guide rail device with adaptive tower profile, comprising: a guide rail body 101 and two mounting plates 105. The guide rail body 101 is slidably connected to the interior of the two mounting plates 105. Multiple locking holes 106 are formed on the outer surface of the two mounting plates 105. Two second fixing blocks 108 are fixedly installed on the outer surface of the guide rail body 101, and two first fixing blocks 107 are fixedly installed on the outer surface of the guide rail body 101. Locking rods 111 are movably embedded inside each of the two second fixing blocks 108. Each locking rod 111 is movably embedded inside one of the locking holes 106, and a limiter is fixedly installed at the top of each locking rod 111. Two circular blocks 110 are fixedly mounted with springs 109 on one side of each of the two limiting circular blocks 110. One end of each of the two springs 109 is fixedly mounted on one side of each of the two first fixing blocks 107. A linkage rod 112 for linkage is fixedly mounted on the opposite side of the two limiting circular blocks 110. A slider 113 is slidably connected inside the guide rail body 101. A connecting block 114 is fixedly mounted on one side of the slider 113. A first rotating rod 115 is movably embedded inside the connecting block 114. A U-shaped block 116 is movably sleeved on the outer surface of the first rotating rod 115. A second rotating rod 117 is movably embedded inside the U-shaped block 116. A movable block 118 is movably sleeved on the outer surface of the second rotating rod 117.
[0026] In use, the staff first installs the mounting plate 105 on top of the tower using screws and nuts. When needed, the staff attaches a safety rope to the top of the movable block 118. The movable block 118 can rotate vertically around the U-shaped block 116 via the second rotating rod 117, and the U-shaped block 116 can rotate horizontally around the connecting block 114 via the first rotating rod 115. After the rope is fixed above the movable block 118, horizontal and vertical movement can be achieved, which can improve the flexibility of the movable block 118. When workers need to move laterally above the tower, pulling the linkage rod 112 causes the limiting blocks 110 on the upper and lower parts of the guide rail body 101 to move in the opposite direction to the mounting plate 105. At this time, the limiting blocks 110 can cause the locking rod 111 to disengage from the inside of the locking hole 106. After disengagement, the guide rail body 101 can move laterally inside the mounting plate 105. After movement, the protection range of the guide rail body 101 during use can be increased, and the working distance of the guide rail body 101 can be increased. Under the limiting action of the two springs 109, the limiting blocks 110 are attached to the outer surface of the second fixing block 108. At this time, the locking rod 111 is locked inside the locking hole 106, which can limit the guide rail body 101 and prevent the guide rail body 101 from sliding inside the mounting plate 105. When adjusted to the required position, it will not easily slide.
[0027] like Figures 1 to 7 As shown, in one embodiment, a compression cylinder 130 is fixedly installed on the outer surface of the guide rail body 101 near its top. A compression block 132 is slidably connected to the inner wall of the compression cylinder 130. A spring 131 is fixedly installed on the top of the compression block 132. A push rod 133 is fixedly installed on the outer surface of the compression block 132 away from the spring 131. The push rod 133 is movably embedded inside the compression cylinder 130. A rectangular strip 134 is fixedly installed at the bottom end of the push rod 133. An oil supply pipe 135 is fixedly installed on one side of the compression cylinder 130 near its top. One end of the oil supply pipe 135... Extending into the interior of the guide rail body 101, when the slider 113 moves to the top of the guide rail body 101, the connecting block 114 contacts the rectangular bar 134, thereby pushing the push rod 133 to move upward. The push rod 133 pushes the extrusion block 132 to slide on the inner wall of the extrusion cylinder 130, which can squeeze the internal lubricating oil to the oil supply pipe 135. Through the oil supply pipe 135, the oil is squeezed to the inner wall of the guide rail body 101, reducing the wear of the slider 113 inside the guide rail body 101. Under the limit of the spring 131, the extrusion block 132 returns to its original position for the next extrusion.
[0028] like Figures 1 to 7As shown, in one embodiment, a take-up roller 120 is rotatably mounted on the top of the guide rail body 101. A steel wire rope 119 is sleeved on the outer surface of the take-up roller 120. One end of the steel wire rope 119 is fixedly connected to the top of the slider 113. A connecting frame 2 is fixedly mounted on the top of the guide rail body 101. When the slider 113 slides upward inside the guide rail body 101, the take-up roller 120 can take up the limiting block 110. When the slider 113 moves downward, the take-up roller 120 can rotate in the opposite direction. The torsion spring 121 allows the take-up roller 120 to pull the slider 113 to the highest point inside the guide rail body 101 without being subjected to any external force. The torsion spring 121 can prevent the steel wire rope 119 from contacting the slider 113 inside the guide rail body 101 when the slider 113 rises, causing the slider 113 to jam.
[0029] like Figures 1 to 7 As shown, in one embodiment, multiple limiting rods 126 are fixedly installed on both the upper and lower sides of the connecting frame 2. A motor 123 is fixedly installed on the top of the connecting frame 2. A gear 127 is fixedly installed on the output end of the motor 123. A first rack 124 is meshed with the outer surface of the gear 127. When a worker accidentally falls, the slider 113 slides rapidly downward inside the guide rail body 101. At this time, the motor 123 rotates rapidly. After rotating, it drives the first rack 124 and the second rack 125 meshed with its surface to move. The limiting rods 126 limit the movement. After moving, the second friction semicircular block 129 and the first friction semicircular block 128 move towards the rotating disk 122. The first friction semicircular block 128 and the second friction semicircular block 129 clamp the outer surface of the rotating disk 122, which can reduce the rotation speed of the rotating disk 122 until it stops rotating, similar to a car brake disc.
[0030] like Figures 1 to 7 As shown, in one embodiment, the outer surface of the gear 127 is meshed with a second rack 125. The first rack 124 and the second rack 125 are slidably connected to the outer surfaces of multiple limit rods 126. A first friction semicircular block 128 is fixedly installed on the outer surface of the first rack 124, and a second friction semicircular block 129 is fixedly installed on the outer surface of the second rack 125. When the rotating disk 122 is locked by the first friction semicircular block 128 and the second friction semicircular block 129, the take-up roller 120 will stop rotating, and the wire rope 119 will instantly pull the slider 113 to stop rotating inside the guide rail body 101.
[0031] like Figures 1 to 7As shown, in one embodiment, a rotating disk 122 is fixedly installed on one side of the take-up roller 120. The first friction semicircular block 128 and the second friction semicircular block 129 are located on the upper and lower sides of the rotating disk 122, respectively. Multiple springs 102 are fixedly installed at the bottom of the guide rail body 101. Two limiting telescopic rods 103 are fixedly installed at the bottom of the guide rail body 101. An elastic plate 104 is fixedly installed on the top of the multiple springs 102 and the two limiting telescopic rods 103. A torsion spring 121 is provided inside the take-up roller 120 as a second layer of protection. When the slider 113 continues to fall inside the guide rail body 101, the slider 113 falls to the bottom of the guide rail body 101 and contacts the upper surface of the elastic plate 104. The large torsion spring 102 can buffer the elastic plate 104, and the limiting telescopic rods 103 limit the elastic plate 104, which can prevent the slider 113 from contacting the bottom of the inner wall of the guide rail body 101 and causing large vibration, thus reducing the risk of injury to workers.
[0032] Working principle: When in use, the operator first installs the mounting plate 105 on top of the tower using screws and nuts. When needed, the operator's safety rope is tied to the top of the movable block 118. The movable block 118 can rotate vertically around the U-shaped block 116 via the second rotating rod 117, and the U-shaped block 116 can rotate horizontally around the connecting block 114 via the first rotating rod 115. After the rope is fixed above the movable block 118, horizontal and vertical movement can be achieved, which can improve the flexibility of the movable block 118. When workers need to move laterally above the tower, pulling the linkage rod 112 causes the limiting blocks 110 on the upper and lower parts of the guide rail body 101 to move in the opposite direction to the mounting plate 105. At this time, the limiting blocks 110 can cause the locking rod 111 to disengage from the inside of the locking hole 106. After disengagement, the guide rail body 101 can move laterally inside the mounting plate 105. After movement, the protection range of the guide rail body 101 during use can be increased, and the working distance of the guide rail body 101 can be increased. Under the limiting action of the two springs 109, the limiting blocks 110 are attached to the outer surface of the second fixing block 108. At this time, the locking rod 111 is locked inside the locking hole 106, which can limit the guide rail body 101 and prevent the guide rail body 101 from sliding inside the mounting plate 105. When adjusted to the required position, it will not easily slide.
[0033] When the slider 113 slides upward inside the guide rail body 101, the take-up roller 120 can take up the limiting block 110. When the slider 113 moves downward, the take-up roller 120 can rotate in the opposite direction. The torsion spring 121 allows the take-up roller 120 to pull the slider 113 to the highest point inside the guide rail body 101 without being subjected to any external force. The torsion spring 121 can prevent the wire rope 119 from contacting the slider 113 inside the guide rail body 101 when the slider 113 rises, causing the slider 113 to jam.
[0034] When a worker accidentally falls, the slider 113 slides rapidly downward inside the guide rail body 101. At this time, the motor 123 rotates rapidly. After rotating, it drives the first rack 124 and the second rack 125, which are meshed on their surfaces, to move. The limit rod 126 limits the movement. After moving, the second friction semicircular block 129 and the first friction semicircular block 128 move towards the rotating disk 122. The first friction semicircular block 128 and the second friction semicircular block 129 clamp the outer surface of the rotating disk 122, which can reduce the rotation speed of the rotating disk 122 until it stops rotating, similar to the brake disc of a car. When the rotating disk 122 is locked by the first friction semicircular block 128 and the second friction semicircular block 129, the take-up roller 120 will stop rotating, and the wire rope 119 will instantly pull the slider 113 to stop rotating inside the guide rail body 101. A second layer of protection is also provided. When the slider 113 continues to fall inside the guide rail body 101, it will fall to the bottom of the guide rail body 101 and contact the upper surface of the elastic plate 104. The large torsion spring 102 can buffer the elastic plate 104, and the limiting telescopic rod 103 can limit the elastic plate 104, which can prevent the slider 113 from contacting the bottom of the inner wall of the guide rail body 101 and causing large vibrations, thus reducing the risk of injury to workers.
[0035] When the slider 113 moves to the top of the guide rail body 101, the connecting block 114 contacts the rectangular bar 134, thereby pushing the push rod 133 to move upward. The push rod 133 pushes the extrusion block 132 to slide on the inner wall of the extrusion cylinder 130, which can squeeze the internal lubricating oil to the oil supply pipe 135. Through the oil supply pipe 135, the oil is squeezed to the inner wall of the guide rail body 101, reducing the wear of the slider 113 inside the guide rail body 101. Under the limit of the spring 131, the extrusion block 132 returns to its original position for the next extrusion.
