Description

Technical Field

[0001] This utility model relates to the field of fall protection device technology, and in particular to a guide and positioning structure for an I-shaped aluminum alloy fall protection device. Background Technology

[0002] Fall arresters are widely used in high-altitude operations, maintenance work at height, and construction, aiming to ensure the safety of workers, prevent accidental falls, and achieve a safe connection between personnel and work equipment. The performance of fall arresters depends not only on the sensitivity of the braking system but also on a reliable guide and positioning structure to ensure the smooth movement and accurate positioning of the device on the track. Through reasonable design, the guide and positioning structure can effectively guide the sliding components to move along the track, improving the safety and ease of use of the device and providing a solid guarantee for high-altitude operations.

[0003] Most existing fall arrestor guidance and positioning structures adopt a rapid braking fall arrest mode, lacking a progressive buffer structure. When a fall incident occurs, it brakes instantaneously in a very short time. Although it can prevent a fall, it is easy to generate a large impact force at the moment of braking, which not only puts an impact load on the equipment structure, but also exerts a strong pulling force on the workers' bodies. In addition, most existing guidance and positioning structures do not have segmented positioning functions, and cannot achieve multi-point positioning of sliding components in the track. At the same time, the lack of symmetrical guidance design makes it easy to sway and deviate, reducing the overall stability and safety of operation.

[0004] Therefore, addressing the problems of the existing guide and positioning structures of fall arrest devices, this invention achieves segmented positioning of the fall arrest device by setting multiple sets of equidistant positioning blocks on the I-shaped guide rail. At the same time, a support and fastening buckle are set to cooperate with the sliding of the cylindrical guide rail, and the fastening spring is used to keep it in close contact to prevent the device from shaking or deviating, thus improving the reliability of the guide. During the fall arrest process, the connecting rope pulls the trapezoidal slider to move along the inner wall of the outer frame. By continuously squeezing the I-shaped guide rail, the friction force is gradually increased, realizing the gradual deceleration of the sliding seat and reliable fall arrest, effectively ensuring the safety of high-altitude operations. Utility Model Content

[0005] To overcome the problems that existing fall arrest devices mostly adopt a rapid braking mode and lack a progressive buffer structure, which can easily generate a large impact at the moment of braking, resulting in severe stress on the equipment and pulling injuries to the staff, in addition, existing guide and positioning structures generally do not have segmented positioning functions, cannot achieve multi-point positioning, and lack symmetrical guide design, which can easily cause the device to shake and deviate, affecting the stability of operation and safety of use.

[0006] The technical solution of this utility model is as follows: a guide and positioning structure for an I-shaped aluminum alloy fall arrestor, comprising an I-shaped guide rail, a connecting block, and an outer frame; mounting seats are fixedly connected to both ends of the I-shaped guide rail, and a columnar guide rail is fixedly connected to the side of the mounting seat near the I-shaped guide rail; the connecting block is slidably connected to both sides of the I-shaped guide rail, and sliders are slidably connected to both sides of the I-shaped guide rail; the sliders are slidably connected to the inner sidewall of the outer frame, and the outer frame is slidably connected to the outer side of the I-shaped guide rail; a connecting rope is fixedly connected to the bottom of the slider, and the end of the connecting rope away from the slider is fixedly connected to the top of the connecting block.

[0007] Preferably, the mounting bases are symmetrically installed at both ends of the I-shaped guide rail, the connecting blocks are symmetrically installed on both sides of the I-shaped guide rail, the slider has a trapezoidal structure, and the inner sidewall of the outer frame has a sloping structure.

[0008] Preferably, the I-shaped guide rail has a slidably connected positioning block inside, the positioning block is equidistantly installed on the back of the I-shaped guide rail, and limit blocks are fixedly connected to both sides of the positioning block, the limit blocks are symmetrically installed near the front of the positioning block.

[0009] Preferably, a return spring is fixedly connected to the front of the positioning inclined block. The return spring is symmetrically installed near both ends of the positioning inclined block. The end of the return spring away from the positioning inclined block is fixedly connected to the inside of the I-shaped guide rail. The inside of the I-shaped guide rail is provided with a sliding groove, and the limiting block is slidably connected to the inside of the sliding groove.

[0010] Preferably, the mounting base has mounting holes on its back side, which are equidistantly distributed on the back side of the mounting base. The connecting block is rotatably connected to rollers, which are rotatably connected to both sides of the I-shaped guide rail. The connecting block is fixedly connected to a sliding seat on its inner side.

[0011] Preferably, the sliding seat is located away from the roller, and a pulley is rotatably connected to the side of the sliding seat near the I-shaped guide rail. The pulleys are symmetrically installed at the four corners of the back of the connecting block, and the pulleys are rotatably connected to the outside of the I-shaped guide rail. A circular buckle is rotatably connected to the front of the sliding seat.

[0012] Preferably, supports are fixedly connected to both sides of the outer frame, and the supports are symmetrically installed on both sides of the outer frame. Limiting rods are slidably connected inside the supports, and the limiting rods are symmetrically installed on both sides of the supports. A fastening spring is sleeved on the outer side of the limiting rod, and a fastening buckle is fixedly connected to the end of the limiting rod away from the support. One end of the fastening spring is fixedly connected to the inside of the support, and the other end of the fastening spring is fixedly connected to the outer side wall of the fastening buckle. The fastening buckle is tightly attached to the outer side wall of the cylindrical guide rail.

[0013] The beneficial effects of this utility model are: When the equipment is ready for use, fix the mounting base in the work area through the mounting holes to keep the I-shaped guide rail and column guide rail vertical. Then, hook the safety buckle onto the ring buckle. When the worker moves, the safety buckle and ring buckle move synchronously. The rollers and pulleys roll along the I-shaped guide rail, driving the sliding seat to move on the front of the I-shaped guide rail. The sliding seat pushes the outer frame to slide upward synchronously, completing the equipment preparation for use. When the equipment performs its positioning function, the outer frame moves along the I-shaped guide rail with the sliding seat. When it moves to the bottom of the positioning wedge, the outer frame can slide to the top. During this process, the positioning wedge is pressed into the inside of the I-shaped guide rail. After the outer frame passes the positioning wedge, the reset spring pushes the positioning wedge back to its original position. Through multiple sets of equidistantly arranged positioning wedges, the outer frame and the sliding seat are segmented and positioned at different positions on the rail. At the same time, the support moves with the outer frame, causing the fastening buckle to slide along the cylindrical guide rail. The fastening spring ensures that the fastening buckle is always close to the cylindrical guide rail, completing the guiding and positioning process. This achieves multi-point positioning and symmetrical guiding design of the sliding component, improving the overall stability and safety of the operation. When the equipment performs its fall protection function, the outer frame falls to the top of the positioning ramp and is stopped there. At this time, the operator uses the safety buckle to drive the ring buckle and the sliding seat to continue falling. The connecting block then applies downward force, and the trapezoidal slider is pulled along the inner wall of the outer frame by the connecting rope. As the slider continues to move down the sloping inner wall, it continuously squeezes the I-shaped guide rail, and the friction between the two gradually increases, effectively slowing down the falling speed of the sliding seat. Finally, the rollers and pulleys stop rolling, and the sliding seat stops falling, achieving progressive fall protection. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6 This utility model provides a technical solution: a guide and positioning structure for an I-shaped aluminum alloy anti-fall device, including an I-shaped guide rail 1, a connecting block 4, and an outer frame 6; mounting bases 2 are fixedly connected to both ends of the I-shaped guide rail 1, and a columnar guide rail 3 is fixedly connected to the side of the mounting base 2 near the I-shaped guide rail 1; the connecting block 4 is slidably connected to both sides of the I-shaped guide rail 1; sliders 5 are slidably connected to both sides of the I-shaped guide rail 1; sliders 5 are slidably connected to the inner side wall of the outer frame 6; the outer frame 6 is slidably connected to the outer side of the I-shaped guide rail 1; a connecting rope 7 is fixedly connected to the bottom of the slider 5; and the end of the connecting rope 7 away from the slider 5 is fixedly connected to the top of the connecting block 4.

[0018] Mounting bases 2 are symmetrically installed at both ends of I-shaped guide rail 1, connecting blocks 4 are symmetrically installed on both sides of I-shaped guide rail 1, slider 5 has a trapezoidal structure, and the inner wall of the outer frame 6 has a sloping structure. The trapezoidal structure of slider 5 and the sloping inner wall of outer frame 6 enable slider 5 to slide smoothly along the slope, and the force-bearing area gradually increases, effectively improving the friction between slider 5 and I-shaped guide rail 1, realizing a linear gradual increase in friction during the fall prevention process, achieving a gradual deceleration and fall prevention effect, and improving the safety of high-altitude operations.

[0019] The I-shaped guide rail 1 has a sliding connection of a positioning inclined block 101. The positioning inclined block 101 is equidistantly installed on the back of the I-shaped guide rail 1. Limiting blocks 102 are fixedly connected to both sides of the positioning inclined block 101. The limiting blocks 102 are symmetrically installed near the front of the positioning inclined block 101. The positioning inclined block 101 enables the fall protection device to achieve segmented positioning when it moves to different heights of the I-shaped guide rail 1, thereby improving the stability of the positioning.

[0020] A return spring 103 is fixedly connected to the front of the positioning inclined block 101. The return spring 103 is symmetrically installed near both ends of the positioning inclined block 101. The end of the return spring 103 away from the positioning inclined block 101 is fixedly connected to the inside of the I-shaped guide rail 1. The inside of the I-shaped guide rail 1 is provided with a sliding groove 104. The limiting block 102 is slidably connected inside the sliding groove 104, which effectively restricts the movement of the positioning inclined block 101 and prevents it from coming off the outside of the I-shaped guide rail 1 during the reset process, thereby improving the stability of the positioning mechanism.

[0021] Mounting holes 201 are provided on the back of mounting base 2. Mounting holes 201 are evenly distributed on the back of mounting base 2. Rollers 401 are rotatably connected inside connecting block 4. Rollers 401 are rotatably connected to both sides of I-shaped guide rail 1. Sliding seat 402 is fixedly connected to the inner side of connecting block 4. Rollers 401 can roll smoothly along I-shaped guide rail 1, reducing movement resistance and improving sliding smoothness.

[0022] The sliding seat 402 is located away from the roller 401. The sliding seat 402 is rotatably connected to the pulley 403 on the side closer to the I-shaped guide rail 1. The pulley 403 is symmetrically installed at the four corners of the back of the connecting block 4. The pulley 403 is rotatably connected to the outside of the I-shaped guide rail 1. The front of the sliding seat 402 is rotatably connected to the ring buckle 404. The pulley 403 can stably fit against the outside of the I-shaped guide rail 1 during the sliding process, preventing the connecting block 4 from shaking or shifting, and improving the stability of the equipment.

[0023] Supports 601 are fixedly connected to both sides of the outer frame 6. The supports 601 are symmetrically installed on both sides of the outer frame 6. Limiting rods 602 are slidably connected inside the supports 601. Limiting rods 602 are symmetrically installed on both sides of the supports 601. A fastening spring 603 is sleeved on the outer side of the limiting rod 602. A fastening buckle 604 is fixedly connected to the end of the limiting rod 602 away from the support 601. One end of the fastening spring 603 is fixedly connected to the inside of the support 601. The other end of the fastening spring 603 is fixedly connected to the outer wall of the fastening buckle 604. The fastening buckle 604 is close to the outer wall of the cylindrical guide rail 3. The limiting rod 602 can effectively limit the movement direction of the fastening spring 603 and the fastening buckle 604 to prevent deviation and shaking.

[0024] Working principle: According to Figures 1 to 4 As shown, when the equipment is ready for use, firstly, the mounting base 2 is fixed in the working area through the mounting hole 201, so that the I-shaped guide rail 1 and the column guide rail 3 are kept vertical. Then, the external safety buckle is hooked onto the ring buckle 404. When the worker moves, the external safety buckle and the ring buckle 404 move synchronously. The roller 401 and the pulley 403 roll along the I-shaped guide rail 1, driving the sliding seat 402 to move on the front of the I-shaped guide rail 1. The sliding seat 402 pushes the outer frame 6 to slide upward synchronously, completing the equipment preparation for use. according to Figures 1 to 5As shown, when the device performs its positioning function, the outer frame 6 moves along the I-shaped guide rail 1 with the sliding seat 402. When it moves to the bottom of the positioning inclined block 101, since the top of the positioning inclined block 101 is a slope structure, the outer frame 6 can slide to the top. During this process, it overcomes the elastic force of the return spring 103 and presses the positioning inclined block 101 into the I-shaped guide rail 1. After the outer frame 6 passes the positioning inclined block 101, under the elastic force of the return spring 103, the positioning inclined block 101 springs back to its original position. At the same time, the limiting block... 102 then synchronously resets along the slide groove 104 to prevent the positioning inclined block 101 from leaving the track. Through multiple sets of equidistantly arranged positioning inclined blocks 101, the outer frame 6 and the sliding seat 402 are segmented and positioned at different positions on the track. At the same time, the support 601 moves with the outer frame 6, causing the fastening buckle 604 to slide along the cylindrical guide rail 3. Under the elastic force of the fastening spring 603, the fastening buckle 604 always sticks to the cylindrical guide rail 3, and the limiting rod 602 effectively restricts its sway, thus completing the guiding and positioning process. according to Figures 3 to 6 As shown, when the equipment performs the fall protection function, the outer frame 6 falls to the top of the positioning inclined block 101. Since the top of the positioning inclined block 101 is perpendicular to the I-shaped guide rail 1, the outer frame 6 is stuck there. At this time, under the action of gravity, the worker drives the ring buckle 404 and the sliding seat 402 to fall continuously through the safety buckle. The connecting block 4 then applies downward force, and the trapezoidal slider 5 is pulled along the inner wall of the outer frame 6 through the connecting rope 7. As the slider 5 continues to move down the sloping inner wall, it continuously squeezes the I-shaped guide rail 1. The friction between the two gradually increases, effectively slowing down the falling speed of the sliding seat 402. Finally, the roller 401 and the pulley 403 stop rolling, and the sliding seat 402 stops falling, realizing progressive fall protection.

[0025] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
