Description

Technical Field

[0001] The utility model relates to the technical field of climbing devices, in particular to a magnetic climbing device. Background Art

[0002] During offshore wind turbine jacket maintenance, the work platform and jacket are typically T-shaped, as they sit in the water. Jackets are circular steel structures ranging in diameter from 1 to 3 meters. Currently, offshore wind turbine jacket maintenance primarily utilizes a Spider-Man slinging method. This approach is challenging, requiring stringent and complex safety measures, and is time-consuming. Furthermore, the annual construction window is limited to approximately five months, subject to typhoons, military exercises, and other constraints. In particular, rust removal and painting of jacket piles is impractical due to their direct contact with seawater, making scaffolding impossible. Furthermore, the platform and jacket piles are constructed using slings, leaving no support points for workers. This limited foot support makes lateral movement difficult, making both single-point and multi-point work difficult, significantly impacting overall construction quality and progress.

[0003] Currently, rust removal and maintenance of pipe piles is performed by installing floating platforms around the piles, with operators working on the platforms. However, due to varying tides from day to day, the size and difficulty of the floating platforms, as well as the technical requirements for rust removal and anti-corrosion painting, significantly limit the time and quality of work.

[0004] Patent CN202120561531.3 discloses a wearable electromagnetic climbing device, which enables a person's limbs to climb diagonally alternately by alternating power supply through a handle and a climbing pedal. The climber needs to carry a power supply device, which increases the weight. If the power supply system suffers from power failure, short circuit, etc., it may cause damage to the climber's personal safety. Utility Model Content

[0005] To address the difficulty and window of opportunity associated with offshore wind turbine conduit maintenance, this utility model provides a magnetic climbing device that can be used as a single-person climbing device. The operator uses both hands and feet to alternately climb to the designated maintenance location. Once at the location, the hand grippers connect to the operator's safety belt, freeing their hands for maintenance work. The waist is supported by the safety belt and the hand grippers.

[0006] The utility model adopts the following technical solutions:

[0011] The support frame is hinged to the abutting protrusion or the fixer, so that the fixer and the abutting protrusion can be turned around the hinge position;

[0012] The magnetic climbing device has an adsorption state and a detachment state. When the magnetic climbing device is in the adsorption state, the magnetic module is adsorbed on the climbing surface, and the abutting protrusion is retracted to be flush with the plane where the magnetic module is located or located inside the plane where the magnetic module is located;

[0013] When the magnetic climbing device is in a disengaged state, the fixer together with the abutting protrusion is driven by the human body to flip toward the climbing surface to lift the magnetic module, thereby breaking the adsorption state of the magnetic module and separating the magnetic module from the climbing surface.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] like Figure 1-4 As shown, a magnetic climbing device is used to magnetically attract a facility or structure having a climbing surface 100 to achieve climbing, and the climbing device includes:

[0032] The adsorption unit 1 includes a support frame 11 and a magnetic module 12 disposed on the support frame 11. The magnetic module 12 has a flat or curved shape that adapts to the climbing surface 100 on the side facing the climbing surface 100.

[0033] A fixator 2, wherein the fixator 2 is provided with a wearable unit 21 adapted to fit the human body;

[0034] abutting protrusion 22, the abutting protrusion 22 being provided on the upper surface of the end portion of the holder 2 and being perpendicular to the holder 2;

[0035] The support frame 11 is hinged to the abutting protrusion 22 or the fixer 2, so that the fixer 2 and the abutting protrusion 22 can be flipped around the hinge position 20;

[0036] The magnetic climbing device has an adsorption state and a detachment state. When the magnetic climbing device is in the adsorption state, the magnetic module 12 is adsorbed on the climbing surface 100, and the abutting protrusion 22 is retracted to be flush with the plane where the magnetic module 12 is located or located inside the plane where the magnetic module 12 is located;

[0037] When the magnetic climbing device is in the disengaged state, the fixer 2 together with the abutting protrusion 22 is driven by the human body to flip toward the climbing surface 100 to lift the magnetic module 12, breaking the adsorption state of the magnetic module 12 and separating the magnetic module 12 from the climbing surface 100.

[0038] In other optional embodiments, a damping unit 23 for contacting the climbing surface 100 is provided on the side of the abutting protrusion 22 facing the climbing surface 100 to increase the friction force when contacting the climbing surface 100 to be sufficient to offset the weight of the human body.

[0039] During use, the fixer 2 is fixed to the limbs of the human body through the wearing unit 21. When the magnetic module 12 approaches a steel structure object, the magnetic module 12 will be completely and tightly adsorbed on the surface of the object under the action of magnetic force. At this time, the magnetic climbing device is in an adsorption state, and the supporting protrusion 22 is retracted to be flush with the plane where the magnetic module 12 is located or located on the inner side of the plane where the magnetic module 12 is located. At this time, the friction between the magnetic climbing device and the climbing surface 100 is proportional to the magnetic attraction force applied to the climbing surface 100. The friction between the climbing device and the climbing surface 100 can offset the gravity of the operator, prevent the climbing device from sliding on the climbing surface 100 due to the influence of the climber's gravity, and provide stable support for the operator. When the friction between the climbing device and the climbing surface 100 is insufficient to offset the gravity of the operator, a damping unit 23 is provided on the side of the supporting protrusion 22 facing the climbing surface 100 to contact the climbing surface to increase the friction between the climbing device and the climbing surface 100. When climbing, the four limbs control the upward movement of the anchor 2, and the magnetic climbing device is now in a disengaged state. The abutting protrusion 22 is then driven to flip toward the climbing surface 100, thereby abutting against the climbing surface and lifting the magnetic module 12, breaking the magnetic module 12's adsorption state and separating the magnetic module 12 from the climbing surface 100, thereby allowing the climbing device to detach from the climbing surface 100. By using the four limbs, one can flexibly and safely climb to the work surface requiring maintenance on the facility or structure, and then connect the safety buckle of the dual-control safety belt to the climbing device. The operator can then perform the corresponding operation and maintenance operations.

[0040] In other optional embodiments, a limiting unit 25 is further provided at the bottom of the support frame 11 to prevent the fastener from flipping back beyond a specified angle. It is generally used in magnetic climbing devices worn on the feet to prevent the fastener from flipping downward beyond a reasonable angle for human standing, allowing operators to step in a more appropriate posture.

[0041] like Figure 2 、 4 As shown, the magnetic module 12 includes one or more permanent magnets, such as magnets or magnetic cores, with strong magnetic force for adsorption to the climbing surface 100 of the facility or structure. In other optional embodiments, the magnetic module 12 has a single-sided magnetic structure, which can concentrate the magnetic flux of the magnetic module 12 on one surface, greatly enhancing the magnetic ability of the adsorption surface.

[0042] like Figure 1-4 As shown, the wearing unit 21 includes one or more common wearing structures such as a wristband, a strap, a quick-release buckle, an elastic band, etc., which is used to quickly and firmly connect the human body to the fixator 2, wear the magnetic climbing device on the body, and prevent it from falling off during operation.

[0043] like Figure 2 、 4 As shown, in other optional embodiments, the magnetic module 12 is provided with an anchor point 26 for hanging a safety rope, which can be used to hang a safety rope or a safety buckle to provide safety support.

[0044] The damping unit 23 includes: a damping pad or a surface concave-convex structure with regular / irregular morphology (not shown). Figure 2 、 4 As shown, in other optional embodiments, the top end of the abutting protrusion 22 is hinged with a first rotating shaft 24, which is used to reduce the friction with the climbing surface 100 when the abutting protrusion 22 abuts against the climbing surface 100, so that the magnetic module 12 can be lifted more easily, thereby achieving the separation of the magnetic module 12 from the climbing surface 100.

[0045] like Figure 2 、 4 As shown, in other optional embodiments, the top end of the support frame 11 is hinged with a second rotating shaft 13 to reduce friction between the top end of the support frame 11 and the climbing surface 100 during the climbing process, making the climbing action smoother.

[0046] like Figure 1-4 As shown, in other optional embodiments, the climbing device is further provided with a power-assisting structure, which includes: a pedal 3 provided on the fixer 2, a handle 4 provided on the support frame 11, and a spring booster 5 connecting the support frame 11 and the fixer 2, or one or more structures, to facilitate the operator to apply force or grasp, thereby reducing the operator's working intensity.

[0047] During use, climbing devices can be divided into hand-worn styles and foot-worn styles according to actual conditions. The difference between the two lies in the adaptive size changes according to different limb structures, as well as the differences in wearing units and power-assisting structures.

[0048] Example 2:

[0049] This embodiment mainly provides a magnetic climbing device suitable for wearing on the feet.

[0050] like Figure 1-2 As shown, a magnetic climbing device is used to magnetically attract a facility or structure having a climbing surface 100 to achieve climbing, and the climbing device includes:

[0051] The adsorption unit 1 includes a support frame 11 and a magnetic module 12 disposed on the support frame 11. The side of the magnetic module 12 facing the climbing surface 100 has a flat or curved shape adapted to the climbing surface 100. The magnetic module 12 includes single-sided magnets arranged in a 2*2 array, which greatly enhances the magnetic ability of the adsorption side.

[0052] A fixator 2 is provided with a wearable unit 21 adapted to fit the human body. The wearable unit 21 includes a strap and a quick-release buckle suitable for wearing on the foot, allowing for quick and secure wearing on the foot.

[0053] abutting protrusion 22, the abutting protrusion 22 being provided on the upper surface of the end portion of the holder 2 and being perpendicular to the holder 2;

[0054] The support frame 11 is hinged to the abutting protrusion 22 or the fixer 2, so that the fixer 2 and the abutting protrusion 22 can be flipped around the hinge position;

[0055] The side of the abutting protrusion 22 facing the climbing surface 100 is provided with a damping unit 23 for contacting the climbing surface 100 to increase the friction force when contacting the climbing surface 100 so as to be sufficient to offset the weight of the human body.

[0056] The climbing device is also provided with a power-assisting structure, which includes: a pedal 3 arranged on the fixer 2 and a spring booster 5 connecting the support frame 11 and the fixer 2. The pedal 3 is used to facilitate the operator to step on it, and the spring booster 5 can make the operator lift his feet more effortlessly.

[0057] The working principle is that the operator quickly and firmly puts the magnetic climbing device on the foot through the wearing unit, and then brings the adsorption unit close to the equipment to be climbed. The magnetic module 12 is firmly attached to the climbing surface through magnetic force. The friction between the climbing device and the climbing surface 100 can offset the operator's weight. When the friction between the climbing device and the climbing surface 100 is insufficient to offset the operator's weight, the damping unit 23 provided on the side of the supporting protrusion 22 facing the climbing surface 100 contacts the climbing surface to increase the friction between the climbing device and the climbing surface 100. When climbing, the foot is lifted upward, and the supporting protrusion 22 is driven to flip toward the climbing surface 100, thereby supporting the climbing surface and tilting the magnetic module 12, breaking the magnetic module 12's adsorption state and separating the magnetic module 12 from the climbing surface 100, allowing the climbing device to detach from the climbing surface 100. The above steps are then repeated.

[0058] Example 3:

[0059] This embodiment mainly provides a magnetic climbing device suitable for hand wear.

[0060] like Figure 3 、 4 As shown, a magnetic climbing device is used to magnetically attract a facility or structure having a climbing surface 100 to achieve climbing, and the climbing device includes:

[0061] The adsorption unit 1 includes a support frame 11 and a magnetic module 12 disposed on the support frame 11. The side of the magnetic module 12 facing the climbing surface 100 has a flat or curved shape adapted to the climbing surface 100. The magnetic module 12 includes single-sided magnets arranged in a 2*2 array, which greatly enhances the magnetic ability of the adsorption side.

[0062] A holder 2 is provided with a wearable unit 21 adapted to fit the human body. The wearable unit 21 includes a wristband, a strap, and a quick-release buckle suitable for hand wear, allowing for quick and secure wear on the hand.

[0063] abutting protrusion 22, the abutting protrusion 22 being provided on the upper surface of the end portion of the holder 2 and being perpendicular to the holder 2;

[0064] The support frame is hinged to the abutting protrusion 22 or the fixer 2, so that the fixer 2 and the abutting protrusion 22 can be flipped around the hinge position 20;

[0065] The side of the abutting protrusion 22 facing the climbing surface 100 is provided with a damping unit 23 for contacting the climbing surface 100 to increase the friction force when contacting the climbing surface 100 so as to be sufficient to offset the weight of the human body.

[0066] The climbing device is further provided with a power-assisting structure, which includes a handle 4 provided on the support frame 11 for easy gripping by the staff.

[0067] The operating principle is the same as that of a magnetic climbing device for the foot. After donning the device, grasp the handles with your hands and bring the attachment unit close to the climbing surface. The magnetic module 12 is firmly attached to the climbing surface through magnetic force. When climbing, the wrist is used to lift up and push against the protrusion 22, thereby separating from the climbing surface 100. An anchor point 26 can be set on the back of the magnetic module 12. When the operator climbs to the working position, the safety belt buckle is hooked into the anchor point. At this time, the force of the body's back is supported by the attachment unit, and the operator can work with both hands free.

[0068] Example 4:

[0069] like Figure 5 As shown, this embodiment is essentially the same as the first embodiment, except that the adsorption unit 1 includes at least two magnetic modules 12, which are hinged in series. Because offshore wind turbine jackets in deepwater areas often have beams of varying diameters, multiple hinged magnetic modules 12 can be attached to beams of varying diameters, helping operators climb without being restricted by the size and angle of the object being adsorbed. If the diameter of the object being adsorbed is less than 1 meter, the number of magnetic modules can be increased to enhance the adsorption force.

[0070] In other optional embodiments, another method of using the magnetic climbing device of the utility model is that when multiple climbing devices need to be placed for the installation of the pedal 3, the climbing device wearing unit 21 can be disassembled and the pedal holder 2 can be installed to flexibly adapt to the required work scene. Several operators enter the designated operation and maintenance position of the catheter pile and adsorb the climbing devices with the pedal holder 2 installed on the catheter pile in turn. Generally, a climbing device is set every 50 centimeters. After the climbing device is adsorbed, the pedal 3 is placed on the holder 2 of the climbing device and the pedal 3 is fixed, and the installation is completed. At this time, the operator can adsorb the hand absorber on the catheter pile, connect the safety belt to the hand absorber, and then the operator can sit on the pedal 3, take off the original foot absorber, and enter the working state.

[0071] In other optional embodiments, another method of using the magnetic climbing device of the utility model is that when large-scale rust removal and painting of the conduit piles are to be carried out, several climbing devices can be connected by aluminum pedals, generally one every 50 centimeters. Multiple climbing devices and aluminum pedals together form a simple scaffolding, providing workers with a working platform for standing, sitting and hanging safety ropes. The climbing devices and aluminum pedals can be set according to the required working area.

[0072] The beneficial effect of the utility model is that the magnetic climbing device of the utility model can be worn on the limbs of the operator, and is adsorbed to the iron wall by a magnetic adsorber controlled alternately by hands and feet. It is easy to control, firmly adsorbed, and does not require power supply. It can be used in both underwater and terrestrial environments. The magnetic unit will not demagnetize in low and high temperature environments, and has a wide range of applicable scenarios.

[0073] For ordinary technicians in this field, based on the teachings of this utility model, without departing from the principles and spirit of this utility model, changes, modifications, replacements and deformations made to the implementation methods are still within the scope of protection of this utility model.
