Description

Technical Field

[0001] This invention relates to the field of construction technology, and in particular to a device for preventing and fixing landscape stones from falling during hoisting. Background Technology

[0002] Landscape stones are core components of garden landscaping, municipal greening, courtyard decoration, and outdoor landscape projects. They are mostly made of natural stone and are characterized by irregular shapes, significant weight, and uneven surfaces. During landscape stone construction, hoisting and relocation are critical processes that directly determine construction efficiency and on-site safety. Currently, the industry commonly uses flexible support nets as the primary hoisting tool for irregularly shaped landscape stones. The flexible wrapping properties of the net adapt to the irregular contours of the stones, offering strong adaptability and ease of operation, thus making it widely used in various landscape stone hoisting construction scenarios.

[0003] Existing flexible support net hoisting structures have significant safety defects and drawbacks, posing serious risks of falling and insecure positioning. During hoisting operations, traditional support net hoisting points are mostly fixed knots and rigid ring structures, which cannot adapt to the shifting center of gravity of the landscape stones and the swaying in the air. This easily leads to uneven stress on the ropes at each hoisting point, and local rope overload can easily cause loosening and breakage. Furthermore, the hoisting points lack buffer restraint structures, making the net prone to sudden movement and opening, which can lead to landscape stone overturning and falling accidents. Summary of the Invention

[0004] In view of this, the present invention proposes a landscape stone hoisting anti-fall and fixing device, which can adaptively adjust the sliding damping of the sliding ball when the center of gravity shifts, suppressing the movement and realizing the anti-fall and fixing of the landscape stone.

[0005] The technical solution of this invention is implemented as follows: A rockery hoisting anti-fall and fixing device includes a support net, connecting rope, cylinder, sliding ball, lifting ring, and damping adjustment mechanism. One end of the connecting rope is connected to the edge of the support net. The bottom surface of the cylinder is provided with a through groove, and its two ends are sealed. The sliding ball is located in the cylinder. The lifting ring is located on the top surface of the cylinder. The end of the connecting rope passes through the through groove and connects to the bottom surface of the sliding ball. The damping adjustment mechanism includes a flexible bladder, magnetorheological fluid, electromagnet, battery pack, and current adjustment mechanism. The flexible bladders are arranged in an array on the top surface of the inner wall of the cylinder. The magnetorheological fluid is filled in the flexible bladders. The electromagnets are symmetrically arranged on the top surface of the cylinder and above the flexible bladders. The battery pack is located on the outer wall of the cylinder. The current adjustment mechanism increases the current supplied by the battery pack to the electromagnet when the sliding ball moves to both sides.

[0006] Preferably, the connecting rope includes an outgoing rope and a movable rod. One end of several outgoing ropes is connected to the edge of the support net, and the other end converges to the end of the movable rod. The other end of the movable rod passes through the through groove and is connected to the outer wall of the sliding ball.

[0007] Preferably, the current regulating mechanism includes a sliding rheostat, a mounting ring, a push plate, and a reset mechanism. The sliding rheostat is symmetrically arranged on the outer wall of the cylinder with respect to the center of the through slot. The mounting ring is sleeved on the movable rod. The push plate is arranged on the outer wall of the mounting ring and located between the sliders of the two sliding rheostats. The sliding rheostat and the electromagnet above it are connected in series to form a circuit. The series circuit is connected in parallel and then connected to the battery pack to form a loop. When the slider of the sliding rheostat moves from the center of the through slot to the outside, its resistance in the circuit decreases. The reset mechanism is used to reset the slider.

[0008] Preferably, the reset mechanism includes a fixed plate and a reset spring. The fixed plate is disposed on both sides of the outer wall of the cylinder. One end of the reset spring is connected to the side wall of the fixed plate, and the other end is connected to the side wall of the sliding rheostat away from the push plate.

[0009] Preferably, the reset mechanism further includes a through hole and a limiting rod. The through hole is disposed on the side wall of the fixed plate, and one end of the limiting rod is connected to the side wall of the slide away from the push plate, and the other end passes through the through hole.

[0010] Preferably, the current regulating mechanism further includes a power-on button, which is disposed on the outer wall of the cylinder. The series circuit is connected in parallel to form a circuit with the battery pack and the power-on button.

[0011] Preferably, the damping adjustment mechanism further includes an electric actuator, which is disposed on the side wall of the push plate, and its output shaft contacts the sliding plate side wall of the sliding rheostat.

[0012] Preferably, a recess is provided at the center of the bottom surface inside the cylinder, the initial position of the sliding ball is located in the recess, and the flexible bladder array is arranged on the top surface of the cylinder on both sides of the recess.

[0013] Preferably, it also includes an alarm mechanism, which includes an audible and visual alarm and a normally open button. The audible and visual alarm is located on the outer side of the cylinder end, and the normally open button is located on the inner side of the cylinder end, forming a circuit with the battery pack and the audible and visual alarm.

[0014] Preferably, the inner top surface of the lifting ring is provided with a snap-fit ​​groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention discloses a rockery hoisting and anti-fall device. The rockery to be installed can be placed in a support net, and the hook can hook onto the lifting ring. Then, the connecting rope is driven upward by the cylinders at different positions of the support net, thus wrapping the rockery. The flexible, porous structure of the support net allows it to be used with rocks of different shapes and sizes, preventing significant swaying. The end of the connecting rope extends into the cylinder and connects to a sliding ball. During hoisting, the sliding ball can slide within a small range inside the cylinder, thereby compensating for the length difference of the connecting ropes at different positions, allowing multiple ropes to move together. The connecting rope is subjected to uniform force to prevent it from falling. In addition, when the landscape stone shakes violently and the sliding ball slides significantly from the center to both sides inside the cylinder, the current adjustment mechanism can increase the current supplied by the battery pack to the electromagnet. This increases the magnetic field strength generated by the electromagnet. Under the influence of the increased magnetic field strength, the viscosity of the magnetorheological fluid increases, and the fluid resistance increases. The flexible bladder can suppress the movement of the sliding ball, preventing it from shifting and further preventing it from falling. This achieves the hoisting and fixing of the landscape stone, avoids safety accidents, and improves construction efficiency. Attached Figure Description

[0018] To better understand the technical content of this invention, a specific embodiment is provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0019] See Figures 1 to 4 This invention provides a landscape stone hoisting anti-fall and fixing device, including a support net 1, a connecting rope 2, a cylinder 3, a sliding ball 4, a lifting ring 5, and a damping adjustment mechanism. One end of the connecting rope 2 is connected to the edge of the support net 1. The bottom surface of the cylinder 3 is provided with a through groove 6, which is sealed at both ends. The sliding ball 4 is located in the cylinder 3. The lifting ring 5 is located on the top surface of the cylinder 3. The end of the connecting rope 2 passes through the through groove 6 and is connected to the bottom surface of the sliding ball 4. The damping adjustment mechanism includes a flexible bladder 7, a magnetorheological fluid 8, an electromagnet 9, a battery pack 10, and a current adjustment mechanism. The flexible bladders 7 are arranged in an array on the top surface of the inner wall of the cylinder 3. The magnetorheological fluid 8 is filled in the flexible bladders 7. The electromagnets 9 are symmetrically arranged on the top surface of the cylinder 3 and located above the flexible bladders 7. The battery pack 10 is located on the outer wall of the cylinder 3. The current adjustment mechanism increases the current supplied by the battery pack 10 to the electromagnet 9 when the sliding ball 4 moves to both sides.

[0020] This invention discloses a landscape stone hoisting anti-fall and fixing device, used for transporting landscape stones to be constructed. After laying the support net 1 flat on the ground or a professional platform, the landscape stone to be constructed is moved onto the support net 1. Connecting ropes 2 are set at multiple points on the edge of the support net 1. The ends of the connecting ropes 2 are connected to the bottom surface of the cylinder 3. Lifting rings 5 ​​are set on the top surface of the cylinder 3. After the crane hook is hooked onto the lifting rings 5, the lifting rings 5 ​​can be pulled up. The lifting rings 5 ​​stretch the connecting ropes 2 to a vertical state through the cylinder 3, thereby pulling the support net 1 at multiple points to wrap the landscape stone. Then the landscape stone can be hoisted to the designated position for construction and installation. The support net 1 can be used for landscape stones of various sizes and shapes, reducing construction costs.

[0021] A through-slot 6 is provided at the bottom of the cylinder 3. The top of the connecting rope 2 extends into the cylinder 3 through the through-slot 6 and connects to the sliding ball 4 in the cylinder 3. The sliding ball 4 can slide slightly inside the cylinder 3, thereby averaging the length difference of the connecting rope 2 at different positions, making the connecting rope 2 at multiple positions evenly stressed, and preventing it from falling. In addition, several flexible bladders 7 are provided on both sides of the center of the top surface inside the cylinder 3. The flexible bladders 7 are filled with magnetorheological fluid 8. At the same time, an electromagnet 9 is provided on both sides of the top surface of the cylinder 3. The magnetic field generated by the electromagnet 9 can adjust the viscosity of the magnetorheological fluid 8. When the magnetic field strength increases, the viscosity of the magnetorheological fluid 8 increases. As the temperature increases and the fluid tends towards a solid state, the sliding ball 4 will come into contact with the flexible bladder 7 when it moves inside the cylinder 3. If the viscosity of the magnetorheological fluid 8 is high, it can provide resistance to the movement of the sliding ball 4. During the hoisting process, if the landscape stone shakes violently, causing the sliding ball 4 to move from the center to both sides, the current adjustment mechanism can increase the current supplied by the battery pack 10 to the electromagnet 9. At this time, the magnetic field strength generated by the electromagnet 9 increases, and the movement of the sliding ball 4 is suppressed by the flexible bladder 7, thereby suppressing the sliding ball 4 from moving around and preventing the sliding ball 4 from hitting both sides of the cylinder 3 and causing the connecting rope 2 to break, thus further achieving the purpose of preventing falling and fixing the landscape stone.

[0022] Preferably, the connecting rope 2 includes an outgoing rope 11 and a movable rod 12. One end of each of the outgoing ropes 11 is connected to the edge of the supporting net 1, and the other end converges to the end of the movable rod 12. The other end of the movable rod 12 passes through the through groove 6 and is connected to the outer wall of the sliding ball 4.

[0023] The movable rod 12 is used to connect the sliding ball 4. Its bottom end is a multi-strand lead-out rope 11. The multi-strand lead-out rope 11 can distribute the force, making the force more even and preventing breakage and falling.

[0024] Preferably, the current regulating mechanism includes a sliding rheostat 13, a mounting ring 14, a push plate 15, and a reset mechanism. The sliding rheostat 13 is symmetrically arranged on the outer wall of the cylinder 3 around the center of the through groove 6. The mounting ring 14 is sleeved on the movable rod 12. The push plate 15 is arranged on the outer wall of the mounting ring 14 and is located between the sliders 16 of the sliding rheostat 13 on both sides. The sliding rheostat 13 and the electromagnet 9 above it are connected to form a series circuit 17. The series circuit 17 is connected in parallel and then connected to the battery pack 10 to form a circuit. When the slider 16 of the sliding rheostat 13 moves outward from the center of the through groove 6, its resistance in the circuit decreases. The reset mechanism is used to reset the slider 16.

[0025] There are two sliding rheostats 13, which are used to adjust the current received by the electromagnets 9 on both sides, thereby controlling the viscosity of the magnetorheological fluid 8 on both sides. When the sliding ball 4 slides in the cylinder 3, it will drive the movable rod 12 to move synchronously. The movable rod 12 is fitted with a mounting ring 14, which can drive the push plate 15 to move synchronously. The push plate 15 is located between the sliders 16 of the two sliding rheostats 13. No matter which side the sliding ball 4 moves from the center, it can push the slider 16 on the same side to move, so that the resistance of the sliding rheostat 13 connected to the series circuit 17 decreases. At this time, the current transmitted from the battery pack 10 to the electromagnet 9 increases, and the viscosity of the magnetorheological fluid 8 is increased by the increased magnetic field strength, thereby increasing the damping of the sliding ball 4 when it slides.

[0026] When the sliding ball 4 returns to the center position, the slider 16 can be reset by the reset mechanism, thereby restoring the fluidity of the magnetorheological fluid 8. There are two sliding rheostats 13 and two electromagnets 9. The sliding rheostats 13 and electromagnets 9 on the same side are connected in series to form a series circuit 17. Then the two series circuits 17 are connected in parallel. In the initial case, the slider 16 of the sliding rheostat 13 is in the middle. At this time, the resistance value connected to the series circuit 17 is at its maximum value, and the magnetic field strength generated by the electromagnet 9 is at its minimum. When the sliding ball 4 moves to either side, it will drive the slider 16 to move, changing its resistance value connected to the series circuit 17.

[0027] Preferably, the reset mechanism includes a fixed plate 18 and a reset spring 19. The fixed plate 18 is disposed on both sides of the outer wall of the cylinder 3. One end of the reset spring 19 is connected to the side wall of the fixed plate 18, and the other end is connected to the side wall of the slider 16 of the sliding rheostat 13 away from the push plate 15.

[0028] When the sliding ball 4 moves toward the center, the return spring 19 on the fixed plate 18 can push the sliding plate 16 to move toward the center of the cylinder 3 in sync, thereby resetting the sliding plate 16.

[0029] Preferably, the reset mechanism further includes a through hole 20 and a limiting rod 21. The through hole 20 is disposed on the side wall of the fixed plate 18, and one end of the limiting rod 21 is connected to the side wall of the slide plate 16 away from the push plate 15, and the other end passes through the through hole 20.

[0030] In order to ensure the stability of the movement of the slider 16, a through hole 20 is provided on the fixed plate 18. The limiting rod 21 passes through the through hole 20. When the slider 16 moves and the return spring 19 is squeezed, the limiting rod 21 can slide along the through hole 20 to ensure that the slider 16 will not deviate during sliding.

[0031] Preferably, the current regulating mechanism further includes a power-on button 22, which is disposed on the outer wall of the cylinder 3. The series circuit 17 is connected in parallel to form a circuit with the battery pack 10 and the power-on button 22.

[0032] The power button 22 is used to control the power on and off of the entire circuit. When the landscape stone is placed in the support net 1 and the cylinder 3 is suspended in the air, the staff can turn on the power through the power button 22. At this time, the circuit is powered on, and the current adjustment mechanism can adjust the magnitude of the current received by the electromagnet 9.

[0033] Preferably, the damping adjustment mechanism further includes an electric push rod 23, which is disposed on the side wall of the push plate 15, and its output shaft contacts the side wall of the slider 16 of the sliding rheostat 13.

[0034] Once the landscape stone is hoisted to the designated position, the electric push rod 23 on the push plate 15 can push the sliders 16 of the two sliding rheostats 13 to move to both sides, thereby increasing the current supplied to the electromagnet 9, which in turn increases the viscosity of the magnetorheological fluid 8 in all the flexible bladders 7. At this time, the sliding ball 4 is clamped in the center of the cylinder 3, thus achieving in-situ fixation of the landscape stone.

[0035] Preferably, a recess 24 is provided at the center of the bottom surface inside the cylinder 3, the initial position of the sliding ball 4 is located in the recess 24, and the flexible bladder 7 is arranged in an array on the top surface of the cylinder 3 on both sides of the recess 24.

[0036] The recess 24 is provided for the initial placement of the sliding ball 4 and can limit the sliding of the sliding ball 4. Only when the cylinder 3 is tilted to a certain angle will the sliding ball 4 disengage from the recess 24 and slide.

[0037] Preferably, it also includes an alarm mechanism, which includes an audible and visual alarm 25 and a normally open button 26. The audible and visual alarm 25 is located on the outer side of the end of the cylinder 3, and the normally open button 26 is located on the inner side of the end of the cylinder 3, forming a circuit with the battery pack 10 and the audible and visual alarm 25.

[0038] If the landscape stone shakes violently, causing the sliding ball 4 to roll to one side of the inner wall of the cylinder 3, the sliding ball 4 will trigger the normally open button 26, causing the normally open button 26 to be triggered into a closed state. At this time, the circuit formed by the audible and visual alarm 25 and the battery pack 10 is connected, and the audible and visual alarm 25 will sound and light an alarm to remind the on-site construction personnel that there is a risk of falling. Similarly, the audible and visual alarm 25 and the normally open button 26 are also connected in series and then form a parallel relationship with another set of audible and visual alarm 25 and normally open button 26.

[0039] Preferably, the inner top surface of the lifting ring 5 is provided with a snap-fit ​​groove 27.

[0040] The locking slot 27 can be locked onto the hook to facilitate the stable movement of the supporting net 1 and the landscape stone.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
