Portable dismountable tower anti-falling device

Abstract

This utility model relates to the field of fall arrestor technology, and in particular to a portable and detachable iron tower fall arrestor, including a fall arrestor guide rail, a clamping mechanism on one side of the fall arrestor guide rail, and a locking mechanism. A deceleration mechanism is located on the upper side of the locking mechanism, and the locking mechanism and deceleration mechanism are located inside the clamping mechanism. The flipping of the locking lever pulls a trigger spring, causing a trigger plate to rotate a V-shaped frame. At this time, the V-shaped frame moves its two hooks away from each other, thus disengaging the V-shaped frame from the lock. Then, a push spring pushes a deceleration pressure frame, causing a deceleration linkage and a deceleration flipping lever to push a deceleration pressure block against the fall arrestor guide rail, thereby decelerating the entire fall arrestor. Simultaneously, the flipping of the locking lever presses the locking pressure block against the side of the fall arrestor guide rail, completing the locking process of the entire fall arrestor.

Description

Technical Field

[0001] This utility model relates to the field of fall arrestor technology, and in particular to a portable and detachable iron tower fall arrestor. Background Technology

[0002] According to the patent document with announcement number CN120154839A, rotating the transmission handle drives the transmission wheel to rotate, which in turn drives the second telescopic rod to rotate. This drives the second transmission helical gear to rotate through the transmission shaft. The second transmission helical gear meshes with the first transmission helical gear, pushing the first vertical wheel to rotate. The first transmission helical gear then drives the lead screw to rotate, causing the threaded parts to move. This brings the first clamping plate and the second clamping plate closer together, and the guide wheel is pressed against the outer wall of the tower guide rail. Afterward, the user adjusts the transmission wheel to move the second telescopic rod and inserts the locking rod to lock the transmission wheel. The connecting piece will drive the preload to descend, triggering the trigger to drive the second transmission gear to rotate. Through the elastic action of the spring rod, the rack meshes with the second transmission gear and rotates, driving the two clamping eccentric wheels to clamp the tower guide rail, thus achieving locking. The patent document states that locking the fall arrestor onto the rail requires the transmission of multiple gears and screws to complete the entire locking process. This undoubtedly increases the weight of the fall arrestor, thereby increasing the load on the person climbing the tower. Furthermore, if the fall arrestor in the document is directly triggered without a relative deceleration structure when a person falls, the moment of locking will generate a large upward pulling force on the person falling due to inertia, which can easily cause injury.

[0004] This utility model achieves the above objectives through the following technical solutions: A portable and detachable tower fall arrestor includes a fall arrestor rail, a clamping mechanism on one side of the fall arrestor rail, a locking mechanism, a deceleration mechanism on the upper side of the locking mechanism, and the locking mechanism and the deceleration mechanism are located inside the clamping mechanism. The deceleration mechanism includes a deceleration pressure frame, with two push springs fixed at the top of the deceleration pressure frame. A deceleration connecting rod and a deceleration flip rod are respectively hinged at the bottom of the deceleration pressure frame. A deceleration pressure block is hinged at one end of the deceleration connecting rod, and a trigger rod is provided at the other end of the deceleration flip rod. Hook plates are fixed on both the front and rear sides of the trigger rod. The locking mechanism includes a locking lever, a locking block at one end of the locking lever, limit blocks fixed on both the front and rear sides of the locking block, a buckle fixed at the end of the locking lever extending out of the clamping mechanism, a V-shaped frame on the upper side of the locking lever, a trigger plate fixed at the end of the V-shaped frame away from the locking block, a trigger spring fixed at the bottom of the trigger plate, hooks for fastening onto the hook plate on both the front and rear sides of the trigger lever, and an arc-shaped block fixed at the end of the hooks near the trigger lever.

[0005] Preferably, the clamping mechanism includes a fixed frame, a pressing side arm is fixed to the front side of one end of the fixed frame, the pressing side arm is connected to the fixed frame by bolts, and a fixing side arm is fixed to the rear side of one end of the fixed frame.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. All electrical components mentioned in this document are electrically connected to an external main controller and 220V AC mains power, and the main controller can be a conventionally known device such as a computer that provides control.

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-8 As shown, a portable and detachable tower fall arrestor includes a fall arrestor rail 4, a clamping mechanism 1 on one side of the fall arrestor rail 4, and a locking mechanism 3. A deceleration mechanism 2 is provided on the upper side of the locking mechanism 3. The locking mechanism 3 and the deceleration mechanism 2 are located inside the clamping mechanism 1.

[0017] In this embodiment: the clamping mechanism 1 includes a fixed frame 11, a pressing side arm 12 is fixed to the front side of one end of the fixed frame 11, the pressing side arm 12 is connected to the fixed frame 11 by bolts, and a fixing side arm 13 is fixed to the rear side of one end of the fixed frame 11. The fixed frame 11 is clamped to the side of the fall arrest guide rail 4 by the pressing side arm 12 and the fixing side arm 13. At this time, one end of the fixed frame 11 is attached to the side of the fall arrest guide rail 4, thereby preventing the fixed frame 11 from detaching from the fall arrest guide rail 4.

[0018] In this embodiment: the deceleration mechanism 2 includes a deceleration pressure frame 23, with two push springs 24 fixed to the top of the deceleration pressure frame 23. A deceleration connecting rod 22 and a deceleration flip rod 25 are respectively hinged to the bottom of the deceleration pressure frame 23. A deceleration pressure block 21 is hinged to one end of the deceleration connecting rod 22, and a trigger rod 26 is provided at the other end of the deceleration flip rod 25. Hook plates are fixed to both the front and rear sides of the trigger rod 26. A deceleration horizontal shaft 6 is provided inside the fixed frame 11 at the position of the deceleration flip rod 25. The deceleration flip rod 25 is rotatably connected to the trigger rod 26. A positioning cover 14 is fixed to the top of the fixed frame 11, and the upper end of the push springs 24 is fixed inside the positioning cover 14. A sliding groove is provided at the other end of the deceleration flip rod 25, and the trigger rod 26... The lower end has a notch, and a top shaft for moving in the sliding groove is fixed in the notch. The spring force of the push spring 24 pushes the deceleration pressure frame 23 to move downward. The downward movement of the deceleration pressure frame 23 causes the connection position of the deceleration connecting rod 22 and the deceleration flip rod 25 to move downward. At this time, one end of the deceleration flip rod 25 flips downward with the deceleration horizontal axis 6 as the center. At the same time, with the cooperation of the deceleration connecting rod 22, it pushes the deceleration pressure block 21 to quickly fit against one side of the fall arrest guide rail 4, thereby completing the deceleration of the entire fall arrester. At the same time, the other end of the deceleration flip rod 25 will flip upward with the deceleration horizontal axis 6 as the center. At this time, the other end of the deceleration flip rod 25 will push the trigger rod 26 upward to extend the fixed frame 11.

[0019] In this embodiment: the locking mechanism 3 includes a locking lever 33, one end of which is provided with a locking block 31. Limit blocks 32 are fixed on both the front and rear sides of the locking block 31. A buckle 34 is fixed to one end of the locking lever 33 that extends out of the clamping mechanism 1. A V-shaped frame 36 is provided on the upper side of the locking lever 33. A trigger plate 35 is fixed to the end of the V-shaped frame 36 away from the locking block 31. A trigger spring 39 is fixed to the bottom of the trigger plate 35. Hooks 37 for fastening onto the hook plate are provided on both the front and rear sides of the trigger lever 26. An arc-shaped block 38 is fixed to one end of hook 37 near trigger rod 26. An arc-shaped groove is provided on the locking pressure block 31 near the locking flip rod 33. Arc-shaped grooves are formed at both ends of the arc-shaped groove. A positioning post for sliding within the arc-shaped groove is fixed to one end of locking flip rod 33. A guide groove is provided inside the fixing frame 11 at the position of limit block 32. A locking horizontal shaft 5 is rotatably connected to the middle position of locking pressure block 31. Both ends of the locking horizontal shaft 5 are fixed inside the fixing frame 11. Inside the fixed frame 11, a triggering horizontal shaft 7 is fixed at the position of the V-shaped frame 36. The V-shaped frame 36 is rotatably connected to the triggering horizontal shaft 7. By pulling the buckle 34, the other end of the locking lever 33 flips downward around the locking horizontal shaft 5. At the same time, one end of the locking lever 33 flips upward along the arc-shaped groove of the locking block 31. At this time, the positioning pin at one end of the locking block 31 slides along the arc-shaped groove, thereby pushing the locking block 31 out of one end of the fixed frame 11. At this time, one end of the locking block 31 is pressed tightly onto the anti-fall guide rail 4. This locks the entire fall arrestor. In addition, when the other end of the locking lever 33 flips downward, the other end of the locking lever 33 pulls the trigger spring 39, causing the trigger plate 35 to flip downward around the trigger horizontal axis 7. At this time, the trigger plate 35 simultaneously drives the V-shaped frame 36 to flip around the trigger horizontal axis 7. During the flipping process of the V-shaped frame 36, the upper end of the V-shaped frame 36 pushes the upper ends of the two hooks 37 away from each other, thereby causing the two hooks 37 to disengage from the hook plate of the trigger lever 26, and then causing the trigger lever 26 to disengage from the fixation.

[0020] Working principle: When in use, first fasten the fixed side arm 13 to the rear side of the fall arrest guide rail 4, and at the same time use bolts to fix the clamping side arm 12 to the front side of the fixing frame 11. At this time, the clamping side arm 12 and the fixed side arm 13 fasten the fixing frame 11 to the fall arrest guide rail 4. When the fall arrest device is in use, fix the rope to the buckle 34. At this time, the fixing frame 11 can be moved up and down along the fall arrest guide rail 4 by the rope of the climber to drive the buckle 34. In the event of a fall, the ropes attached to the climber will quickly pull on the buckle 34. Pulling the buckle 34 causes the other end of the locking lever 33 to flip downwards around the locking horizontal axis 5. The other end of the locking lever 33 pulls the trigger spring 39, causing the trigger plate 35 to flip downwards around the trigger horizontal axis 7. Simultaneously, the trigger plate 35 drives the V-frame 36 to flip around the trigger horizontal axis 7. During the flipping of the V-frame 36, the upper end of the V-frame 36 pushes the upper ends of the two hooks 37 away from each other, causing the two hooks 37 to disengage from the hook plate of the trigger lever 26. This then allows the trigger lever 26 to disengage from its fixed position. At the same time, the spring force of the push spring 24 pushes the deceleration pressure frame 23 to move downward. The downward movement of the deceleration pressure frame 23 causes the connection position of the deceleration linkage 22 and the deceleration flip rod 25 to move downward. At this time, one end of the deceleration flip rod 25 flips downward with the deceleration horizontal axis 6 as the center. At the same time, with the cooperation of the deceleration linkage 22, it pushes the deceleration pressure block 21 to quickly fit against one side of the fall arrest guide rail 4, thereby completing the deceleration of the entire fall arrester. Meanwhile, the other end of the deceleration flip rod 25 will flip upward with the deceleration horizontal axis 6 as the center. At this time, the other end of the deceleration flip rod 25 will push the trigger rod 26 upward to extend the fixed frame 11. While the deceleration block 21 decelerates, one end of the locking lever 33 flips and slides upward along the arc-shaped groove of the locking block 31. At this time, the positioning pin at one end of the locking block 31 slides along the arc-shaped groove, thereby pushing the locking block 31 out of one end of the fixing frame 11. At this time, one end of the locking block 31 presses against the fall arrestor guide rail 4, thereby locking the entire fall arrestor.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
