Description

Technical Field

[0001] This utility model relates to the field of boom lifting machine technology, specifically a variable frequency speed control self-winding boom lifting machine. Background Technology

[0002] Existing variable frequency speed-controlled self-winding rope hoisting machines flexibly adjust the wire rope length to adapt to dynamic stage requirements, such as different performances, scene changes, and the installation position of the load. However, after the wire rope length is changed, the fixed drum length can easily lead to a mismatch between the changed wire rope length and the winding space. This can cause the wire rope to become tangled or overlapping during winding, potentially leading to wire rope breakage, a fall, and a safety accident.

[0003] Therefore, this utility model provides a variable frequency speed control self-winding rope hoisting machine to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing variable frequency speed control self-winding rope hoisting machine is prone to rope tangling and overlapping due to the mismatch between the length and winding space caused by the replacement of the wire rope.

[0005] This utility model provides the following technical solution: a variable frequency speed control self-winding rope hoist, including a length adjustment component, a position adjustment component, and a wire harness component. A through groove is opened in the base body, and two horizontally symmetrical position adjustment components are installed in the through groove. A two-segment length adjustment component is fixedly installed above the horizontally symmetrical position adjustment components, thereby driving the two-segment length adjustment components to move through the horizontally symmetrical position adjustment components. A wire harness component is installed on the side of the base body, and the wire harness component moves linearly relative to the two-segment length adjustment components.

[0006] The length adjustment component includes a first drive motor, an outer drum, a cooperating body, an inner drum, and a first linear driver. The outer drum is fixedly mounted to the first drive motor in the horizontal direction. The inner drum is slidably mounted inside the outer drum through the cooperating body. The first linear driver is fixedly mounted between the outer drum and the inner drum along the axial direction.

[0007] The cooperating body includes end plates and guide grooves. The end plates are fixedly installed at both ends of the inner drum along the axial direction. The end plates are fixedly installed on the surface of the end plates. The guide grooves that accommodate the axial sliding of the protrusions are opened inside the outer drum.

[0008] The position adjustment component includes a second linear actuator and a sliding plate. The second linear actuator is fixedly installed in the through groove, and the sliding plate is slidably installed in the through groove. The sliding plate is fixedly installed at the end of the linear actuator.

[0009] The sliding plate includes a left sliding plate and a right sliding plate, which are horizontally mounted in the through groove. The left sliding plate is fixedly mounted at the end of the second linear drive, and the right sliding plate is freely mounted in the through groove. An outer roller and an inner roller are fixedly mounted on the left and right sliding plates, respectively.

[0010] The wire harness includes a third linear actuator, a slider, and a pulley. The third linear actuator is fixedly mounted on the side of the base, and the slider is fixedly mounted on the end of the third linear actuator. The slider is located at the center of the pulley shaft.

[0011] Both ends of the outer drum are fixedly provided with stops extending in the axial direction.

[0012] The beneficial effects of this utility model are as follows: 1. In this utility model, the inner drum can slide and extend within the outer drum, thereby matching the length of the wire rope with the winding space on the surfaces of the inner and outer drums. This avoids redundant wire rope accumulating on the drum, facilitates matching wire ropes of different lengths, and prevents tangled or overlapping ropes due to mismatched winding space.

[0013] 2. This utility model uses a position adjustment component to change the positions of the inner and outer drums, thereby automatically arranging the wire rope neatly on the drums, ensuring uniformity during winding and preventing rope tangling and overlapping. Simultaneously, it can also move pulleys relative to the surfaces of the outer and inner drums, allowing adjustment of the wire rope's position on either drum surface, further improving the neatness of the wire rope arrangement and further preventing rope tangling and overlapping.

[0021] To address the problem of rope tangling and overlapping caused by mismatch between the length and winding space when replacing wire ropes in existing variable frequency speed control self-winding boom machines, this disclosure provides a variable frequency speed control self-winding boom machine, including a length adjusting component 2, a position adjusting component 3, and a wire harness 4. A through groove 11 is provided in the base 1, and two horizontally symmetrical position adjusting components 3 are installed in the through groove 11. A two-segment length adjusting component 2 is fixedly installed above the horizontally symmetrical position adjusting components 3, thereby moving the two-segment length adjusting components 2 through the horizontally symmetrical position adjusting components 3. A wire harness 4 is installed on the side of the base 1, and the wire harness 4 moves linearly relative to the two-segment length adjusting components 2.

[0022] The horizontally symmetrical position adjustment component 3 drives the length adjustment components 2 at both ends to move, thereby changing the position of the variable frequency speed-regulating self-aligning rope hoist in this embodiment of the present disclosure. This automatically arranges the wire rope neatly on the drum, ensuring uniformity during winding and avoiding rope tangling and overlapping. Simultaneously, the extension and retraction of the length adjustment component 2 controls the effective length of the drum, winding only the corresponding length of wire rope, avoiding redundant wire rope accumulation on the drum, and facilitating the matching of wire ropes of different lengths, thus preventing rope tangling and overlapping due to mismatched winding space. Furthermore, the movement of the wire harness 4 relative to the length adjustment component 2 guides the entry position of the wire rope during winding, further improving the neatness of the wire rope arrangement and winding, and further preventing rope tangling and overlapping.

[0023] The length adjusting component 2 includes a first drive motor 21, an outer drum 22, a cooperating body 23, an inner drum 24, and a first linear actuator 25. The outer drum 22 is fixedly installed in the horizontal direction of the first drive motor 21. The inner drum 24 is slidably installed inside the outer drum 22 through the cooperating body 23. The first linear actuator 25 is fixedly installed between the outer drum 22 and the inner drum 24 along the axial direction.

[0024] During use, the first drive motor 21 is started to drive the outer drum 22 to rotate and wind the wire rope. Simultaneously, the outer drum 22 rotates and winds the inner drum 24, which is driven to rotate synchronously via the cooperating body 23. When dealing with wire ropes of different lengths, the first linear actuator 25 is started to drive the inner drum 24 to move linearly synchronously. During this linear movement, the inner drum 24 extends or retracts by sliding within the outer drum 22 via the cooperating body 23. This extension and retraction of the inner drum 24 within the outer drum 22 controls the overall winding space, preventing redundant wire rope from accumulating on the drum. This facilitates matching wire ropes of different lengths and avoids tangled or overlapping ropes due to mismatched winding space.

[0025] It should be noted that the first drive motor 21 in this embodiment of the present disclosure achieves variable frequency speed regulation during the winding process by using an existing frequency converter or an existing pole-changing speed-regulating motor, which is beneficial to improving the flexibility of use. This variable frequency speed regulation technology is a mature existing technology and will not be described in detail here.

[0026] The cooperating body 23 includes an end plate 231 and a guide groove 232. The end plate 231 is fixedly installed at one end of the inner drum 24 located axially inside the outer drum 22. A protrusion 233 is fixedly installed on the surface of the end plate 231. A guide groove 232 is provided inside the outer drum 22 to accommodate the axial sliding of the protrusion 233.

[0027] During the sliding process of the inner drum 24 within the outer drum 22, the end plate 231 at the end of the inner drum 24 is located inside the outer drum 22, and the protrusion 233 on the surface of the end plate 231 slides within the guide groove 232. This allows the inner drum 24 to slide linearly within the outer drum 22 and extend while rotating with the outer drum 22, thereby enabling the winding space to be adjusted by extending and retracting while rotating in coordination.

[0028] The position adjustment component 3 includes a second linear actuator 31 and a sliding plate 32. The second linear actuator 31 is fixedly installed in the through groove 11, and the sliding plate 32 is slidably installed in the through groove 11. The sliding plate 32 is fixedly installed at the end of the linear actuator.

[0029] It should be noted that an outer drum 22 is rotatably mounted above the sliding plate 32 via an existing bracket, the first drive motor 21 is fixedly mounted on the bracket, and the first drive motor 21 is fixedly mounted at the end of the outer drum 22.

[0030] The second linear driver 31 is activated to drive the sliding plate 32 to slide in the through groove 11, thereby driving the length adjustment member 2 above the sliding plate 32 to move synchronously, thereby changing the position of the variable frequency speed regulation self-winding rope hoisting machine in this embodiment, so as to automatically arrange the wire rope neatly on the drum, ensuring uniformity during the winding process and avoiding rope tangling and overlapping.

[0031] The sliding plate 32 includes a left sliding plate 321 and a right sliding plate 322. The left sliding plate 321 and the right sliding plate 322 are horizontally slidably installed in the through groove 11. The left sliding plate 321 is fixedly installed at the end of the second linear driver 31, and the right sliding plate 322 is freely slidably installed in the through groove 11. An outer roller 22 and an inner roller 24 are fixedly installed on the left sliding plate 321 and the right sliding plate 322, respectively.

[0032] The left sliding plate 321 and the right sliding plate 322 can satisfy the relative movement of the outer drum 22 and the inner drum 24, that is, the inner drum 24 moves and extends within the outer drum 22, which facilitates the adjustment of the winding space, avoids redundant wire rope from accumulating on the drum, and is conducive to matching wire ropes of different lengths, avoiding tangled ropes and overlapping ropes due to mismatched winding space.

[0033] An outer drum 22 is fixedly installed on the left slide plate 321, so that the position of the outer drum 22 can be kept from moving randomly by the second linear drive 31.

[0034] In the process of adjusting the position of the variable frequency speed-regulating self-aligning rope hoist in this embodiment of the present disclosure, thereby automatically arranging the wire rope neatly on the drum, the second linear driver 31 is activated to drive the left slide plate 321 to slide in the through groove 11, thereby driving the outer drum 22 to move synchronously. The movement of the outer drum 22 drives the inner drum 24 to move synchronously. The inner drum 24 is kept in position with the outer drum 22 by the first linear driver 25 and moves by the right slide plate 322, thereby completing the adjustment of the position of the variable frequency speed-regulating self-aligning rope hoist.

[0035] The wire harness 4 includes a third linear actuator 41, a slider 42, and a pulley 43. The third linear actuator 41 is fixedly installed on the side of the base 1, and the slider 42 is fixedly installed at the end of the third linear actuator 41. The slider 42 is located at the axis of the pulley 43.

[0036] The third linear actuator 41 is activated to drive the pulley 43 to move synchronously, thereby moving the pulley 43 relative to the surfaces of the outer drum 22 and the inner drum 24. This allows the position of the wire rope wound on the surface of the outer drum 22 or the inner drum 24 to be adjusted through the pulley 43, thereby further improving the neatness of the wire rope winding and further avoiding rope tangling and overlapping.

[0037] It should be noted that the first linear actuator 25, the second linear actuator 31 and the third linear actuator 41 can adopt any existing structure or device capable of linear movement, such as a cylinder, a hydraulic cylinder, an electric actuator or an electric lead screw.

[0038] Both ends of the outer drum 22 are fixedly provided with baffles 26 extending in the axial direction. The baffles 26 can limit the movement distance of the inner drum 24 within the outer drum 22, thereby preventing the inner drum 24 from detaching from the outer drum 22 and improving safety during use.

[0039] During the adjustment of the frequency conversion speed regulation self-winding rope hoisting machine in the embodiments of this disclosure: First, the first drive motor 21 is started to drive the outer drum 22 and the inner drum 24 to rotate and wind the wire rope. During the winding process, the second linear drive 31 is started and drives the left slide plate 321 to slide in the through groove 11, thereby driving the outer drum 22 to move synchronously. The movement of the outer drum 22 drives the inner drum 24 to move synchronously. The inner drum 24 is kept in position with the outer drum 22 by the first linear drive 25 and moves by the right slide plate 322, thereby adjusting the position of the variable frequency speed regulation self-aligning rope hoisting machine, so as to automatically arrange the wire rope neatly on the drum, ensuring uniformity during the winding process and avoiding rope tangling and overlapping.

[0040] Simultaneously, based on the length of the wire rope, the first linear actuator 25 is activated to drive the end plate 231 and the inner drum 24 to slide in the guide groove 232 within the outer drum 22, thereby controlling the extension and retraction length of the inner drum 24. This allows the length of the wire rope to match the winding space on the surfaces of the inner drum 24 and the outer drum 22, thus preventing redundant wire rope from accumulating on the drum. This facilitates matching wire ropes of different lengths and avoids tangled or overlapping ropes due to mismatched winding spaces.

[0041] Meanwhile, during the winding of the wire rope, the third linear actuator 41 is activated to drive the slider 42 to slide linearly, thereby driving the pulley 43 to move synchronously. This causes the pulley 43 to move relative to the surfaces of the outer drum 22 and the inner drum 24, thereby adjusting the position of the wire rope wound on the surface of the outer drum 22 or the inner drum 24 through the pulley 43. This further improves the neatness of the wire rope winding and further avoids tangled ropes and overlapping ropes.
