Description

Technical Field

[0001] This application relates to the field of aerospace equipment technology, and in particular to a portable rope length adjuster. Background Technology

[0002] When hoisting the entire rocket horizontally, the lifting position should be at the rocket's center of gravity. However, if the rocket's center of gravity is not at the lifting position during the lifting process, the length of the ropes needs to be adjusted to reposition the rocket's center of gravity so that it is at the lifting position. Therefore, the rope length needs to be adjusted. Currently, methods for adjusting the rope length include winding and adding lifting rings. However, the rope adjustment process is relatively cumbersome and difficult, and it consumes a lot of manpower. For example, patent CN201921158052.6 discloses a rocket combination lifting device. The technical problem solved by this patent is how to provide a rocket combination lifting device that is reasonably designed, structurally stable, safe and reliable, and can accurately adjust the force on the lifting point. However, the lifting device in this patent is heavier and more complex in structure under the same rated load, and the lifting device as a whole is not lightweight. Summary of the Invention

[0003] The purpose of this application is to provide a portable rope length adjuster to address the above-mentioned problems.

[0004] This application provides a portable rope length adjuster, comprising:

[0005] A support frame, comprising two support plates arranged along a first direction, with a rotating shaft between the two support plates, and an accommodating space formed within the support frame;

[0006] A winding frame is provided within the accommodating space and sleeved around the rotating shaft, and can rotate about the axis of the rotating shaft. A channel for rope passage is formed on the winding frame, and there is at least one winding post on each side of the channel. The axis of the winding post extends along the first direction.

[0007] A locking component is disposed between the winding frame and the support frame;

[0008] When the locking component is in the locked state, it locks the relative positional relationship between the winding frame and the support frame at least along the direction of the tightening rope.

[0009] When the locking component is in the unlocked state, the locking component is used to release the relative positional relationship between the winding frame and the support frame;

[0010] A drive assembly is provided on the support frame, which, when the locking assembly is in the unlocked state, drives the winding frame to rotate around the rotation axis.

[0011] According to the technical solution provided in the embodiments of this application, the winding frame includes a bearing plate arranged parallel to the support plate, the bearing plate is provided with the winding post, and the other end of the winding post is connected to a handle, the handle being parallel to the bearing plate.

[0012] According to the technical solution provided in the embodiments of this application, the number of winding posts is two, and the two winding posts are parallel to each other.

[0013] According to the technical solution provided in the embodiments of this application, the locking component includes a rotating disk disposed on the side of the handle away from the support plate, the outer periphery of the rotating disk is engraved with uniformly arranged teeth, the support plate is provided with a driving component, the driving end of the driving component is provided with a limiting member, and the limiting member is engaged with the teeth.

[0014] According to the technical solution provided in the embodiments of this application, the driving component includes an adjustment handle, which is rotatably disposed on the side of the support plate away from the handle. Both ends of the adjustment handle are respectively provided with protrusions extending along the first direction. The end of the limiting member away from the teeth is provided with a movable handle, which is provided with a strip-shaped hole extending along the second direction, which is perpendicular to the first direction.

[0015] According to the technical solution provided in the embodiments of this application, two first limiting rods extending along the first direction are also provided between the two support plates, and the two first limiting rods are respectively located on both sides of the winding frame.

[0016] According to the technical solution provided in the embodiments of this application, the rotating disk is a ratchet.

[0017] According to the technical solution provided in the embodiments of this application, the limiting member is a ratchet.

[0018] Compared with the prior art, the beneficial effects of this application are as follows: This application includes a support frame with a rotating shaft inside, around which the winding frame rotates, forming a channel for rope passage on the winding frame. At least one winding post is provided on each side of the channel. It also includes a locking component between the winding frame and the support frame. When the locking component is in the locked state, it can lock the relative position between the winding frame and the support frame along the direction of rope release. When the locking component is in the unlocked state, it releases the relative position between the winding frame and the support frame. Furthermore, a driving component is provided on the support frame, which drives the winding frame when the locking component is in the unlocked state. The device rotates around a rotating axis. During use, the rope passes through the channel and onto the winding post. When the rope needs to be tightened, the locking component causes the winding frame to rotate in one direction (e.g., clockwise) around the axis of rotation, thus winding the rope around the winding frame. When the rope needs to be extended, the driving component unlocks the locking component, thereby driving the winding frame to rotate in the opposite direction (e.g., counterclockwise) around the axis of rotation. This application enables the tightening and extension of the rope by providing a winding frame that can rotate around the axis of rotation within the support frame, and by providing a locking component and a driving component.

[0030] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0031] Please refer to Figures 1-9 This embodiment provides a portable rope length adjuster, including:

[0032] A support frame, comprising two support plates 1 arranged along a first direction, a rotating shaft 2 provided between the two support plates 1, and an accommodating space formed within the support frame;

[0033] A winding frame is provided within the accommodating space and sleeved around the rotating shaft 2, and can rotate around the axis of the rotating shaft 2. A channel for rope passage is formed on the winding frame, and there is at least one winding post 6 on each side of the channel. The axis of the winding post 6 extends along the first direction.

[0034] A locking component is disposed between the winding frame and the support frame;

[0035] When the locking component is in the locked state, it locks the relative positional relationship between the winding frame and the support frame at least along the direction of the tightening rope.

[0036] When the locking component is in the unlocked state, the locking component is used to release the relative positional relationship between the winding frame and the support frame;

[0037] A drive assembly is provided on the support frame. When the locking assembly is in the unlocked state, it is used to drive the winding frame to rotate around the rotating shaft 2.

[0038] Specifically, in this embodiment, the two support plates 1 are arranged along a first direction, which is... Figure 2 In the vertical direction, both support plates 1 are as follows: Figure 2As shown in the diagram, a rotating shaft 2 is positioned between the two support plates 1. Both ends of the rotating shaft 2 are fixedly connected to the two support plates 1, for example, by welding. The two support plates 1 and the rotating shaft 2 together form a receiving space. A winding frame is provided within this space, and the winding frame is fitted around the rotating shaft 2, allowing it to rotate around its axis. A channel for rope passage is formed on the winding frame, and at least one winding post 6 is provided on each side of the channel. The axis of the winding post 6 extends along the first direction. A locking assembly is provided between the winding frame and the support frame. The component has two states. When the locking component is in the locked state, it can change the relative position between the winding frame and the support frame at least along the direction of tightening the rope. When the locking component is in the unlocked state, it can release the relative position between the winding frame and the support frame, causing the winding frame to rotate around the axis of the rotation shaft 2, thereby releasing the rope. The support frame is also provided with a drive component. When the locking component is in the unlocked state, the drive component can drive the winding frame to rotate around the axis of the rotation shaft 2, thereby releasing the rope.

[0039] During use, the way the rope is threaded is as follows: Figure 1 For details, please refer to the above. Figure 2 When the locking component is in the locked state, the winding frame can rotate counterclockwise around the axis of the rotating shaft to wind the rope; when the locking component is in the unlocked state, the driving component can drive the winding frame to rotate clockwise around the axis of the rotating shaft to release the rope, thereby enabling the adjustment of the rope length.

[0040] This application includes a winding frame that can rotate around the axis of rotation within a support frame. Ropes are wound on the winding column of the winding frame, and the two ends of the ropes are connected to the two ends of the entire arrow. A locking component and a driving component are also provided. When the projectile is lifted and its attitude is not horizontal, the attitude of the projectile can be adjusted by adjusting the length of the slings so that the projectile can reach a horizontal state during lifting.

[0041] For further details, please see Figure 2 The winding frame includes a support plate 4 arranged parallel to the support plate 1. The support plate 4 is provided with the winding post 6. The other end of the winding post 6 is connected to a handle 5. The handle 5 is parallel to the support plate 4.

[0042] Specifically, in this embodiment, the winding frame includes a support plate 4 and a handle 5. The support plate 4, the handle 5 and the support plate 1 are parallel to each other, and a winding post 6 is provided between the support plate 4 and the handle 5. The winding post 6 extends along the first direction, and the winding post 6 is fixedly connected to the support plate 4 and the handle 5.

[0043] For further details, please see Figure 2 The number of winding posts 6 is two, and the two winding posts 6 are parallel to each other.

[0044] Specifically, in this embodiment, the two winding posts 6 are parallel to each other.

[0045] Furthermore, the locking assembly includes a rotating disk 7 disposed on the side of the handle 5 away from the support plate 4, the outer periphery of the rotating disk 7 is engraved with evenly arranged teeth, the support plate 1 is provided with a driving assembly, the driving end of the driving assembly is provided with a limiting member 8, and the limiting member 8 is engaged with the teeth.

[0046] Specifically, in this embodiment, please refer to... Figure 3 The locking component includes a rotating disk 7, which is disposed on the side of the handle 5 away from the support plate 4 and is fixedly connected to the handle 5. When the handle 5 rotates, the rotating disk 7 will also rotate. The rotating disk 7 has evenly arranged teeth on its periphery. A driving component is provided on the support frame, and a limiting member 8 is provided at the driving end of the driving component. The limiting member 8 engages with the teeth.

[0047] Please refer to the following for details during use. Figure 3 When the rope needs to be tightened, the handle is turned counterclockwise, and the rotating disc fixed to the handle also rotates counterclockwise. The winding post also rotates counterclockwise, allowing the rope to be wound around the winding post. When the rope needs to be released, the drive component drives the limiting member to rotate clockwise. After the limiting member on the rotating disc is released, the drive component stops rotating. At this time, one end of the limiting member leaves the teeth, and the rotating disc can rotate clockwise with the handle. The winding frame also rotates clockwise, allowing the rope to be released.

[0048] Furthermore, the drive assembly includes an adjustment handle 9, which is rotatably disposed on the side of the support plate 1 away from the handle 5. The two ends of the adjustment handle 9 are respectively provided with protrusions 10 extending along the first direction. The end of the limiting member 8 away from the teeth is provided with a movable handle 11. The movable handle 11 is provided with a strip hole 12 extending along the second direction, which is perpendicular to the first direction. The protrusions 10 can move within the strip hole 12.

[0049] Specifically, in this embodiment, please refer to... Figure 2 One end of the rotating disk 7 is provided with a protruding connecting part, please see details. Figure 3 The adjusting handle 9 has a plug-in portion at one end near the rotating disk 7. The plug-in portion is sleeved around the connecting portion, and the two are rotatably connected. One of the support plates 1 is sleeved around the connecting portion. The adjusting handle 9 and the support plate 1 are parallel to each other, that is, the adjusting handle 9 extends along a second direction, which is horizontal and perpendicular to the first direction. Protrusions 10 are also provided at both ends of the adjusting handle 9. Both protrusions 10 extend along the first direction and extend in opposite directions from both sides of the adjusting handle 9. The movable handle 11 also has a strip-shaped hole 12. Figure 2 As shown, extending along the second direction, the protrusion 10 is movable within the strip hole 12.

[0050] Please refer to the following during use: Figure 3 When the rope needs to be tightened, turn the handle counterclockwise, and the rope can be wound onto the winding frame. When the rope needs to be released, turn the adjusting handle counterclockwise. The protrusion on the left side of the adjusting handle will rotate counterclockwise, causing the movable handle to rotate clockwise. Because the movable handle and the limiting component are also fixedly connected, the rotating component will rotate clockwise. Similarly, the protrusion on the right side of the adjusting handle will rotate counterclockwise, and the movable handle will rotate clockwise, causing the limiting component on the right side to rotate clockwise. In this way, the limiting component can be used to limit the rotation between the rotating discs, allowing the rope to be released.

[0051] Furthermore, two first limiting rods 13 extending along the first direction are provided between the two support plates 1, and the two first limiting rods 13 are respectively located on both sides of the winding frame.

[0052] Specifically, in this embodiment, a first limiting rod 13 is provided between the two support plates 1. The number of the first limiting rods 13 in this embodiment is two, and the two first limiting rods 13 extend along the first direction, and the two first limiting rods 13 are respectively located on both sides of the winding frame.

[0054] Specifically, in this embodiment, the ratchet is a type of existing technology; for details of its structure, please refer to [link / reference needed]. Figure 4 .

[0055] Furthermore, the limiting member 8 is a ratchet.

[0056] Specifically, in this embodiment, the pawl is a type of existing technology; for details of its structure, please refer to [link / reference needed]. Figure 6 .

[0057] The portable rope length adjuster provided in this application embodiment includes a winding frame inside a support frame, which can rotate around a rotation axis. A channel for rope passage is formed on the winding frame, and at least one winding post is provided on each side of the channel. It also includes a locking component disposed between the winding frame and the support frame. When the locking component is in a locked state, it can lock the relative positional relationship between the winding frame and the support frame along the direction of rope release. When the locking component is in an unlocked state, it is used to release the relative positional relationship between the winding frame and the support frame. A driving component is also provided on the support frame, which drives the winding frame to rotate around the rotation axis when the locking component is in the unlocked state.
