Description

Technical Field

[0001] The present application belongs to the field of slings, and in particular to a rope guiding mechanism and a sling and an aircraft comprising the same. Background Art

[0002] The background description provided herein is intended to generally present the context of the disclosure.

[0003] Hoisting equipment is widely used in the fields of construction engineering, manufacturing, and cargo transportation. Hoisting equipment in the prior art mainly relies on a winch or hoist to collect or lower the rope to perform lifting operations. However, since the rope is usually wound along the length or height of the winch or hoist, the rope will swing when it is collected and released, thereby causing friction with the winch or hoist, the object being hoisted, etc., increasing the friction in the lifting operation. At the same time, the swing of the rope is also easy to cause it to get entangled with the surrounding objects, or cause the hoisted object to shake, thereby causing safety hazards. In the prior art, an anti-jumping device is used to reduce the swing of the rope. This anti-jumping device is usually composed of a pulley and a baffle, which can reduce the swing of the rope to a certain extent, but because it can only provide one force application point, its anti-swing effect is limited, and since the anti-jumping device is usually fixedly installed, the rope will rub against the pulley or baffle when it swings, increasing the friction.

[0004] Therefore, it is desired to provide a new rope guiding mechanism and a lifting device. Utility Model Content

DETAILED DESCRIPTION

[0028] The exemplary embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the following description is only exemplary in nature and is not intended to limit the present application, application or use.

[0029] The present application will now be further described. In the following paragraphs, different aspects of the present application are defined in more detail. Unless clearly indicated to the contrary, each aspect so defined may be combined with any other (multiple) aspects. In particular, any feature indicated as being preferred or advantageous may be combined with any other (multiple) features indicated as being preferred or advantageous.

[0030] Refer to the attached Figure 1 and attached Figure 2 The present application provides a new rope guiding mechanism 100. The rope guiding mechanism 100 according to the principle of the present application includes a wire jumper 110 and a wire passing bracket 120, wherein the wire jumper 110 is connected to the wire passing bracket 120, and the wire passing bracket 120 is provided with a first wire passing through hole 121, and the first wire passing through hole 121 has a first end 121a and a second end 121b. Preferably, the length of the first wire passing through hole 121 is greater than its aperture, such as more than 1 times its aperture, such as between 1 and 10 times, between 1 and 5 times, and between 1 and 3 times. The anti-wire jump device 110 is arranged on one side of the first end 121a close to the first wire passing hole, and the anti-wire jump device 110 includes a bearing 111 and baffles 112 arranged on both sides of the bearing 111, and the bearing 111 has an inner ring and an outer ring, wherein the outer ring of the bearing 111 can be provided with a V-shaped groove surrounding the bearing 111, so that when the rope passes through the bearing 111, the rope can be stored in the V-shaped groove and the rope swing can be reduced.

[0031] As mentioned above, the baffles 112 provided on both sides of the bearing 111 can prevent the rope from detaching from the bearing 111. The inner ring of the bearing 111 is connected to the wire-passing bracket 120 by bolts, so that the outer ring of the bearing 111 can rotate relative to the inner ring, thereby reducing the friction between the rope and the bearing 111. Advantageously, the wire-passing bracket 120 is provided with two lugs 126, and the inner ring of the bearing 111 is connected to the two lugs 126 by bolts, so that the anti-jump wire device 110 is maintained between the two lugs 126. During use, the rope extending from the winch passes through the anti-jump wire device 110, passes through the first wire-passing through hole 121 and extends, so that the rope is not only restricted by the anti-jump wire device 110, but also by the first wire-passing through hole 121, thereby greatly reducing the swing of the rope.

[0032] Advantageously, the wire-passing bracket 120 further includes a first mounting plate 122, which is disposed on a side of the wire-passing prevention device 110 away from the first wire-passing through hole. The first mounting plate 122 can be rotatably connected to a device, such as a sling, for mounting the rope guide mechanism 100, so that the wire-passing prevention device 110 and the wire-passing bracket 120 can rotate with the swing of the rope. Compared with a fixedly mounted rope guide mechanism, this rotatable connection can keep the rotation of the rope guide mechanism consistent with the swing of the rope, thereby reducing the friction between the rope and the rope guide mechanism and extending the service life of the rope and the rope guide mechanism.

[0033] Refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 3Advantageously, the wire-passing bracket 120 further includes a second mounting plate 123, which is disposed at the second end 121b, and the second mounting plate 123 is provided with a damper 124. The damper 124 includes a damper first body 124a and a damper second body 124b, and the damper first body 124a and the damper second body 124b can rotate relative to each other, and friction is generated between the two when rotating. The second mounting plate 123 can be connected to the first body 124a or the second body 124b. The damper 124 can be provided with a second wire-passing through hole 125, wherein the second wire-passing through hole 125 can be aligned with the first wire-passing through hole 121, so that the rope extending from the first wire-passing through hole 121 can pass through the damper 124, and the damper 124 can also limit the rope, thereby further reducing the swing of the rope. During use, one body of the damper 124 is connected to the second mounting plate 123, and the other body is connected to a device for installing a rope guiding mechanism, such as a hanger. In this way, when the wire passing bracket 120 and the anti-jump wire device 110 rotate with the swing of the rope, the damper 124 can provide damping to hinder the rotation of the wire passing bracket 120 and the anti-jump wire device 110, thereby reducing the rotation speed and rotation amplitude of the wire passing bracket 120 and the anti-jump wire device 110, and preventing them from rotating too fast or too large to cause the rope to be entangled in the rope guiding mechanism or other equipment.

[0034] See attached Figure 1 and attached Figure 2 Advantageously, the rope guiding mechanism according to the principles of the present application may further include a fixed frame 130, wherein the fixed frame 130 may include a third mounting plate 131, the third mounting plate 131 is rotatably connected to the first mounting plate 122, for example, the third mounting plate 131 may be connected to the first mounting plate 122 via a flange bearing and a shaft, so that the anti-jump wire device 110 and the wire-passing bracket 120 can be rotated relative to the fixed frame 130. The fixed frame 130 may further include a fourth mounting plate 132, the fourth mounting plate 132 is connected to the damper 124, so that the first body 124a and the second body 124b of the damper 124 can be relatively rotated between the fourth mounting plate 132 and the second mounting plate 123.

[0035] Advantageously, the fixed frame 130 may include a first frame 130a and a second frame 130b, and the first frame 130a and the second frame 130b are arranged at an angle, for example, 90°, and the anti-jump wire device 110 and the wire-passing bracket 120 may be arranged in the angle, so as to prevent the anti-jump wire device 110 and the wire-passing bracket 120 from rotating too much and causing the rope to be entangled. Advantageously, the ports of the first wire-passing through hole 121 and the second wire-passing through hole 125 are provided with anti-wear linings 127 to prevent the rope from wearing the ports, and the anti-wear linings 127 may be made of ceramic material, alloy material or composite material.

[0036] See attached Figure 4 The present application also provides a sling 200, which includes a load-bearing plate 210 and a winch unit 220 disposed on the load-bearing plate 210, wherein the winch unit 220 includes a rope guiding mechanism 100 according to the principle of the present application, a winch body 221, a rope 222 wound around the winch body 221, and a motor 223. The motor 223 can be configured to drive the winch body 221 to achieve the retraction and release of the rope 222. The winch body 221 and the motor 223 can be arranged in one piece or in a separate piece. There can be more than two winch units 220, for example, four. The sling 200 can be used as a lifting device, that is, as a fixed end, to lift a load-bearing device with a lifted object located below it by retracting and releasing the rope 222; it can also be used as a load-bearing device, that is, as a movable end, to lower or rise below the lifting device by retracting and releasing the rope 222 to carry the lifted object. When the sling 200 is used as a load-bearing device, a hook, a gripper or a cargo box may also be provided to hook, grab or accommodate the object to be lifted.

[0037] See attached Figure 5 , the edge of the load-bearing plate 210 may be provided with a wall 230, and the wall 230 may extend along the edge toward one side of the load-bearing plate 210 and surround the load-bearing plate 210 so as to form a box-like structure with the load-bearing plate 210. Alternatively, the wall 230 may not surround the load-bearing plate 210. Advantageously, the winch unit 220 may also be provided on the wall 230. The wall 230 is provided with a hollow 231 to reduce the weight of the sling. The wall 230 may include a first wall 232 and a second wall 233, and the first wall 232 and the second wall 233 may be respectively provided at opposite edges of the load-bearing plate 210, for example, when the load-bearing plate 210 is rectangular, the first wall 232 is provided at two opposite edges of the rectangle, and the second wall 233 may be provided at the other two opposite edges. A battery pack 234 may be placed in the first wall 232 to provide power to an electrical device such as a motor 223 provided in the sling 200, thereby strengthening the integrity of the battery pack 234 and the sling 200 and saving installation space.

[0038] Advantageously, the sling 200 further includes a propeller mounting frame 240 for mounting a propeller 241, and the propeller mounting frame 240 is arranged on the outer side of the wall 230, for example, it can be connected to the outer side of the first wall 232. The propeller 241 can be a propeller, or a gas or liquid nozzle. When the sling 200 as a load-bearing device encounters factors such as wind force during the lifting process and swings in the horizontal direction, the propeller 240 can provide a force opposite to the swinging direction to prevent the swinging of the sling, thereby achieving the stability of the sling. In addition, when the sling 200 as a load-bearing device is in the process of descending, if it is not directly above the cargo or the predetermined delivery point, the propeller 240 can provide a corresponding driving force, so that the sling 200 is close to the cargo or the predetermined delivery point directly above, so as to grab or deliver the cargo. The propeller mounting frame 240 can include a first body 240a and a second body 240b, and the second body 240b is arranged at both ends of the first body 240a and is perpendicular to the first body 240a. The propeller mounting frame 240 may be disposed on two opposite sides of the sling, and the first body 240a and the second body 240b may be provided with propellers 241, thereby providing propulsion forces in different directions for the sling.

[0039] The rope guide mechanism 100 may also be disposed in the thruster mounting frame 240, in which case the rope extending from the winch body 221 may pass through the hollow 231 of the wall 230 and then continue to extend through the rope guide mechanism 100. Advantageously, the fixing frame 130 of the rope guide mechanism may be integrally formed with the thruster mounting frame 240, preferably located at the connection between the first body 240a and the second body 240b of the mounting frame 240.

[0040] The present application also provides an aircraft, which includes a sling 200 according to the principles of the present application. The sling 200 can be connected to the aircraft through a rope as a load-bearing device, and the sling 200 rotates through the winch disc 221 to retract the rope, so as to achieve the action of raising or lowering relative to the aircraft, so as to retract and release the hoisted object. The sling 200 can also be fixed on the aircraft as a hanging device, connected to the load-bearing device through a rope, and rotates through the winch disc 221 to retract the rope, so that the load-bearing device below it can achieve the action of raising or lowering relative to the aircraft, so as to retract and release the hoisted object. It is easy for those skilled in the art to understand that when the sling 200 is used as a hanging device, it does not need to be provided with a propeller and a propeller mounting frame. In the aircraft according to the principles of the present application, after one end of the rope 222 of the sling 200 extends from the winch disc 221, it passes through the anti-jump wire 110, the first wire through hole 121, the second wire through hole 125 in sequence, and is connected to the aircraft or the load-bearing device.

[0041] The aircraft according to the principles of the present application can be an unmanned aircraft or a manned aircraft.

[0042] The rope guiding mechanism and the sling according to the principle of the present application can provide multiple force application points for the rope, thereby effectively preventing the rope from swinging. Moreover, since the rope guiding mechanism can not only rotate with the swing of the rope, but also provide damping to limit the swing speed and swing amplitude of the rope guiding mechanism, the friction between the rope and the rope guiding mechanism can be reduced, thereby further improving the anti-swing effect of the rope and extending the service life of the rope and the rope guiding mechanism.

[0043] Although at least one exemplary embodiment is described in the foregoing detailed description, it should be understood that there are a large number of variations. It should also be understood that an exemplary embodiment or multiple exemplary embodiments described herein are merely examples and are not intended to limit the scope, applicability or configuration of the present application in any way.
