Description

Technical Field

[0001] This utility model relates to the field of wire reeling machine technology, and in particular to a wire reeling machine for building construction. Background Technology

[0002] During construction, cables are needed to power the construction machinery to ensure normal operation. Depending on the machinery and its purpose, cables are generally divided into single-phase 220V and three-phase 380V cables. To prevent cables from getting tangled, tripping construction workers, or being crushed by equipment, and to facilitate carrying them for future use, cables are usually wound up and stored using a winding device when not in operation.

[0003] Most existing cable reel machines are single-roll structures, while construction sites often need to manage multiple voltage cables such as 220V and 380V at the same time. Cable reel machines lack effective isolation structures, and different voltage cables are prone to tangling and mixing during the winding process, which is inconvenient for subsequent operations by workers. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a wire reel machine for building construction.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a winding machine for construction includes a winding frame with a U-shaped structure. A rotating tube rotatably connected to the winding frame is installed through one side of the frame. Two first baffles symmetrically arranged about the middle of the rotating tube are fixedly sleeved on the rotating tube. A rotating column is rotatably installed on the other side of the frame. The rotating column passes through the rotating tube. A second baffle is fixedly sleeved on the rotating column. The winding frame is provided with a drive mechanism for driving the rotating tube and the rotating column to rotate synchronously.

[0006] By adopting the above technical solution, firstly, two wires of different voltages are wound around the rotating tube and rotating column. Then, the driving mechanism is operated to drive the rotating tube and rotating column to rotate synchronously, so that the cables of the two voltages can be wound up on the rotating tube and rotating column. Due to the shielding of the first baffle and the second baffle, the two cables are prevented from tangling after being wound up, so that the staff can use them later.

[0007] Furthermore, the drive mechanism includes a drive assembly, which includes a drive box fixed to the winding frame, a first gear fixedly sleeved on the rotating tube, a second gear fixedly sleeved on the rotating column, a spline shaft rotatably mounted in the drive box, and a drive motor fixed to the drive box and driving the spline shaft to rotate. The drive mechanism also includes a transmission assembly for driving the first gear and the second gear to rotate.

[0008] By adopting the above technical solution, the operation transmission component drives the first gear and the second gear to rotate, thereby causing the rotating tube fixed to the first gear and the rotating column fixed to the second gear to rotate, thus ensuring the normal winding or unwinding operation of the device.

[0009] Furthermore, the transmission assembly includes a third gear rotatably sleeved on the spline shaft and meshing with the first gear, a fourth gear rotatably sleeved on the spline shaft and meshing with the second gear, a first synchronizing ring disposed on the third gear and coaxially disposed on the third gear, and a second synchronizing ring disposed on the fourth gear and coaxially disposed on the fourth gear. The drive mechanism also includes a locking assembly for keeping the spline shaft and the third gear, and for keeping the spline shaft and the fourth gear in a stationary state.

[0010] By adopting the above technical solution, when the drive motor is working, it drives the spline shaft to rotate. Under the action of the locking component, the spline shaft and the third gear and the spline shaft and the fourth gear are kept in a stationary state, thereby making the spline shaft, the fourth gear and the third gear rotate synchronously, so as to achieve the purpose of rotating the first gear meshing with the third gear and the second gear meshing with the fourth gear.

[0011] Furthermore, the locking assembly includes a first inner spline tube slidably sleeved on the spline shaft and splinedly connected to the spline shaft, a second inner spline tube slidably sleeved on the spline shaft and splinedly connected to the spline shaft, a third synchronizing ring fixed on the second inner spline tube and meshing with the second synchronizing ring, a fourth synchronizing ring fixed on the first inner spline tube and meshing with the first synchronizing ring, a first connecting plate rotatably sleeved on the first inner spline tube, and a second connecting plate rotatably sleeved on the second inner spline tube. The driving mechanism also includes a displacement assembly for driving the first connecting plate and the second connecting plate to move. The second inner spline tube and the fourth gear are jointly provided with an adjustment assembly for driving the fourth gear to rotate independently.

[0012] By employing the above technical solution, the displacement component drives both the first and second connecting plates to move, thereby causing the fourth synchronous ring connected to the first connecting plate and the third synchronous ring connected to the second connecting plate to move towards the drive motor, until the first and fourth synchronous rings, and the third and second synchronous rings, disengage. At this point, the spline shaft rotation cannot drive the third and fourth gears to rotate. Similarly, the displacement component drives both the first and second connecting plates to move in opposite directions, thereby causing the fourth synchronous ring connected to the first connecting plate and the third synchronous ring connected to the second connecting plate to move away from the drive motor, until the first and fourth synchronous rings, and the third and second synchronous rings, re-engage. At this point, the spline shaft rotation can drive the third and fourth gears to rotate synchronously.

[0013] Furthermore, the displacement assembly includes a crossbar fixed inside the drive box, a lead screw rotatably installed inside the drive box, and a displacement motor fixed to the drive box and driving the lead screw to rotate. The crossbar passes through the first connecting plate and the second connecting plate in sequence and is slidably engaged with the first connecting plate and the second connecting plate. The lead screw passes through the first connecting plate and the second connecting plate in sequence and is threadedly connected with the first connecting plate and the second connecting plate.

[0014] By adopting the above technical solution, the displacement motor drives the lead screw to rotate when it is working, and under the limit of the crossbar, the first connecting plate and the second connecting plate can move.

[0015] Furthermore, the adjustment assembly includes a fifth synchronization ring fixed to the other end of the first inner spline tube and coaxially arranged, and a sixth synchronization ring arranged on the fourth gear and coaxially arranged with the fourth gear. A transmission block is rotatably mounted on the first connecting plate, and a transmission groove is provided on the first inner spline tube to slide with the transmission block.

[0016] By adopting the above technical solution, the first connecting plate and the second connecting plate move a certain distance toward the drive motor. The second connecting plate drives the second inner spline tube and the third synchronous ring to move away from the second synchronous ring until the third synchronous ring is separated from the second synchronous ring. During this process, the first connecting plate drives the transmission block to move along the transmission groove until the transmission block is in contact with the side wall of the transmission groove near the drive motor. At this time, the fourth synchronous ring is still in a meshing state with the first synchronous ring. When the spline shaft rotates, it will only cause the third gear to rotate, thus operating the rotating tube to rotate independently. Similarly, if the first connecting plate and the second connecting plate continue to move toward the drive motor, since the side wall of the transmission block near the drive motor is in contact with the transmission groove, the first inner spline tube connected to the locking assembly and the fifth synchronous ring connected to the first inner spline tube will move synchronously until the fifth synchronous ring meshes with the sixth synchronous ring. At this time, the fourth synchronous ring is separated from the first synchronous ring. The rotation of the spline shaft can cause the fourth gear to rotate independently, thus operating the rotating column to rotate independently. The operator can operate the rotating column, the rotating tube, or both simultaneously as needed.

[0017] Furthermore, the first, sixth, and second synchronizing rings are all fixed with connecting pipes coaxially arranged with the spline shaft. The connecting pipe on the first synchronizing ring is rotatably connected to the third gear, the connecting pipe on the second synchronizing ring is rotatably connected to one side of the fourth gear, and the connecting pipe on the sixth synchronizing ring is rotatably connected to the other side of the fourth gear. Torsion springs are fixed between the first and third synchronizing rings, between the second and fourth synchronizing rings, and between the fourth and sixth synchronizing rings. The sixth synchronizing ring, the first synchronizing ring, and the second synchronizing ring are all provided with a limiting component.

[0018] By adopting the above technical solution, during the engagement of the sixth synchronous ring with the fifth synchronous ring, the engagement of the fourth synchronous ring with the first synchronous ring, and the engagement of the second synchronous ring with the third synchronous ring, the tooth blocks of the first, sixth, and second synchronous rings contact with the tooth blocks of the fifth, third, and fourth synchronous rings and generate force. The connecting pipe rotates under the force and drives the torsion spring to contract, thereby buffering the force generated by the tooth blocks of the first, sixth, and second synchronous rings and the tooth blocks of the fifth, third, and fourth synchronous rings, which plays a protective role. At the same time, it makes the engagement process of the sixth synchronous ring with the fifth synchronous ring, the fourth synchronous ring with the first synchronous ring, and the second synchronous ring with the third synchronous ring smoother.

[0019] Furthermore, the first, sixth, and second synchronization rings are all provided with limiting through holes. The number of limiting components is equal to the number of limiting through holes, and their positions correspond one-to-one. Each limiting component includes a connecting block slidably disposed within the limiting through hole and an arc-shaped sliding rod fixed within the limiting through hole and slidably engaged with the connecting block. The connecting block on the first synchronization ring is fixed to the third gear, and the connecting blocks on the sixth and second synchronization rings are both fixed to the fourth gear.

[0020] By adopting the above technical solution and restricting the component settings, it is ensured that when the fifth, third, and fourth synchronous rings rotate, power is transmitted to the first, sixth, and second synchronous rings, respectively.

[0021] In summary, this utility model has the following beneficial effects: In this application, by improving the existing technical structure, the situation of tangling after the two types of cables are wound up is avoided, so that the staff can use them later. Attached Figure Description

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 1-5 As shown in the illustration, this application discloses a cable winding machine for construction, including a winding frame 1, a drive mechanism 6, an adjustment component 7, and a limiting component 13. The winding frame 1 has a U-shaped structure. A rotating tube 2, rotatably connected to the winding frame 1, is installed through one side of the frame. Two first baffles 3, symmetrically arranged about the middle of the rotating tube 2, are fixedly fitted on the rotating tube 2. A rotating column 4 is rotatably mounted on the other side of the frame, passing through the rotating tube 2. A second baffle 5 is fixedly fitted on the rotating column 4. First, two different voltage wires are wound around the rotating tube 2 and the rotating column 4. Then, the drive mechanism 6 is operated to drive the rotating tube 2 and the rotating column 4 to rotate synchronously, thereby winding the two voltage cables around the rotating tube 2 and the rotating column 4. Due to the obstruction of the first baffles 3 and the second baffles 5, tangling of the two cables after winding is avoided, facilitating subsequent use by workers.

[0026] A drive mechanism 6 is mounted on the take-up frame 1 and is used to drive the rotating tube 2 and the rotating column 4 to rotate synchronously. The drive mechanism 6 includes a drive assembly 61, a transmission assembly 62, a locking assembly 63, and a displacement assembly 64. The drive assembly 61 includes a drive housing 611, a first gear 612, a second gear 613, a splined shaft 614, and a drive motor 615. The drive housing 611 is fixed to the take-up frame 1, and the first gear 612 is fixedly sleeved on the rotating tube 2. The second gear 613 is fixedly sleeved on the rotating column 4. The splined shaft 614 is rotatably mounted inside the drive housing 611, and the drive motor 615 is fixed to the drive housing 611 and drives the splined shaft 614 to rotate. Operating the transmission assembly 62 drives the first gear 612 and the second gear 613 to rotate, thereby causing the rotating tube 2, which is fixed to the first gear 612, and the rotating column 4, which is fixed to the second gear 613, to rotate, thus ensuring normal take-up or unwinding operations of the device.

[0027] The transmission assembly 62 is used to drive the first gear 612 and the second gear 613 to rotate. The transmission assembly 62 includes a third gear 621, a fourth gear 622, a first synchronizing ring 623, and a second synchronizing ring 624. The third gear 621 is rotatably sleeved on the splined shaft 614 and meshes with the first gear 612. The fourth gear 622 is rotatably sleeved on the splined shaft 614 and meshes with the second gear 613. The first synchronizing ring 623 is disposed on the third gear 621 and is coaxially disposed on the third gear 621. The second synchronizing ring 624 is disposed on the fourth gear 622 and is coaxially disposed on the fourth gear 622. When the drive motor 615 is working, it drives the spline shaft 614 to rotate. Under the action of the locking component 63, the spline shaft 614 and the third gear 621 and the spline shaft 614 and the fourth gear 622 are kept in a stationary state, thereby making the spline shaft 614, the fourth gear 622 and the third gear 621 rotate synchronously, so as to achieve the purpose of rotating the first gear 612 meshing with the third gear 621 and the second gear 613 meshing with the fourth gear 622.

[0028] The locking assembly 63 is used to keep the spline shaft 614 stationary between itself and the third gear 621, and between itself and the fourth gear 622. The locking assembly 63 includes a first inner spline tube 631, a second inner spline tube 632, a third synchronizing ring 633, a fourth synchronizing ring 634, a first connecting plate 635, and a second connecting plate 636. The first inner spline tube 631 is slidably sleeved on the spline shaft 614 and splinedly connected to it. The second inner spline tube 632 is slidably sleeved on the spline shaft 614 and splinedly connected to it. The third synchronizing ring 633 is fixed to the second inner spline tube 632 and meshes with the second synchronizing ring 624. The fourth synchronizing ring 634 is fixed to the first inner spline tube 631 and meshes with the first synchronizing ring 623. The first connecting plate 635 is rotatably sleeved on the first inner spline tube 631, and the second connecting plate 636 is rotatably sleeved on the second inner spline tube 632. The displacement component 64 drives both the first connecting plate 635 and the second connecting plate 636 to move, thereby causing the fourth synchronous ring 634 connected to the first connecting plate 635 and the third synchronous ring 633 connected to the second connecting plate 636 to move towards the drive motor 615, until the first synchronous ring 623 and the fourth synchronous ring 634, and the third synchronous ring 633 and the second synchronous ring 624, to disengage. At this point, the spline shaft 614 cannot drive the third gear 621 and the fourth gear 622 to rotate. Similarly, the displacement component 64 drives both the first connecting plate 635 and the second connecting plate 636 to move in opposite directions, thereby causing the fourth synchronous ring 634 connected to the first connecting plate 635 and the third synchronous ring 633 connected to the second connecting plate 636 to move away from the drive motor 615, until the first synchronous ring 623 and the fourth synchronous ring 634, and the third synchronous ring 633 and the second synchronous ring 624, to re-engage. At this point, the rotation of the spline shaft 614 can drive the third gear 621 and the fourth gear 622 to rotate synchronously.

[0029] The displacement assembly 64 is used to drive the first connecting plate 635 and the second connecting plate 636 to move. The displacement assembly 64 includes a crossbar 641, a lead screw 642, and a displacement motor 643. The crossbar 641 is fixed inside the drive housing 611, and the lead screw 642 is rotatably mounted inside the drive housing 611. The crossbar 641 passes through the first connecting plate 635 and the second connecting plate 636 in sequence and is slidably engaged with both connecting plates 635 and 636. The lead screw 642 passes through the first connecting plate 635 and the second connecting plate 636 in sequence and is threadedly connected to both connecting plates 635 and 636. The displacement motor 643 is fixed to the drive housing 611 and drives the lead screw 642 to rotate. When the displacement motor 643 is working, it drives the lead screw 642 to rotate, thereby achieving the purpose of moving the first connecting plate 635 and the second connecting plate 636 under the limitation of the crossbar 641.

[0030] An adjusting assembly 7 is jointly mounted on the second internal spline tube 632 and the fourth gear 622, and is used to drive the fourth gear 622 to rotate independently. The adjusting assembly 7 includes a fifth synchronizing ring 71 and a sixth synchronizing ring 72. The fifth synchronizing ring 71 is fixed to the other end of the first internal spline tube 631 and is coaxially mounted. The sixth synchronizing ring 72 is mounted on the fourth gear 622 and is coaxially mounted with it. A transmission block 8 is rotatably mounted on the first connecting plate 635, and a transmission groove 9 is formed on the first internal spline tube 631 that slides with the transmission block 8. The first connecting plate 635 and the second connecting plate 636 move a certain distance toward the drive motor 615. The second connecting plate 636 drives the second inner spline tube 632 and the third synchronous ring 633 to move away from the second synchronous ring 624 until the third synchronous ring 633 and the second synchronous ring 624 are separated. During this process, the first connecting plate 635 drives the transmission block 8 to move along the transmission groove 9 until the transmission block 8 is in contact with the side wall of the transmission groove 9 that is closer to the drive motor 615. At this time, the fourth synchronous ring 634 and the first synchronous ring 623 are still in meshing. When the spline shaft 614 rotates, it will only cause the third gear 621 to rotate, thereby operating the rotating tube 2 to rotate independently. Similarly, the first connecting plate 635 and the second connecting plate 636 continue to move towards the direction of the drive motor 615. Since the side wall of the transmission block 8 near the drive motor 615 is in contact with the transmission groove 9, the first inner spline tube 631 connected to the locking assembly 63 and the fifth synchronous ring 71 connected to the first inner spline tube 631 move synchronously until the fifth synchronous ring 71 meshes with the sixth synchronous ring 72. At this time, the fourth synchronous ring 634 is separated from the first synchronous ring 623. The rotation of the spline shaft 614 can make the fourth gear 622 rotate independently, thereby operating the rotating column 4 to rotate independently. The operator can operate the rotating column 4 independently, operate the rotating tube 2 independently, or operate the rotating tube 2 and the rotating column 4 simultaneously as needed.

[0031] A connecting pipe 10, coaxially arranged with the splined shaft 614, is fixed on the first synchronizing ring 623, the sixth synchronizing ring 72, and the second synchronizing ring 624. The connecting pipe 10 on the first synchronizing ring 623 is rotatably connected to the third gear 621. The connecting pipe 10 on the second synchronizing ring 624 is rotatably connected to one side of the fourth gear 622, and the connecting pipe 10 on the sixth synchronizing ring 72 is rotatably connected to the other side of the fourth gear 622. Torsion springs 11 are fixed between the first synchronizing ring 623 and the third gear 621, between the second synchronizing ring 624 and the fourth gear 622, and between the fourth gear 622 and the sixth synchronizing ring 72. Limiting holes 12 are provided through the first synchronizing ring 623, the sixth synchronizing ring 72, and the second synchronizing ring 624. During the engagement of the sixth synchronizing ring 72 with the fifth synchronizing ring 71, the fourth synchronizing ring 634 with the first synchronizing ring 623, and the second synchronizing ring 624 with the third synchronizing ring 633, the teeth of the first synchronizing ring 623, the sixth synchronizing ring 72, and the second synchronizing ring 624 contact with the teeth of the fifth synchronizing ring 71, the third synchronizing ring 633, and the fourth synchronizing ring 634 and generate force. The connecting pipe 10 rotates under the force and drives the torsion spring 11 to contract, thereby buffering the force generated by the teeth of the first synchronizing ring 623, the sixth synchronizing ring 72, and the second synchronizing ring 624 with the teeth of the fifth synchronizing ring 71, the third synchronizing ring 633, and the fourth synchronizing ring 634, thus playing a protective role. At the same time, it makes the engagement of the sixth synchronizing ring 72 with the fifth synchronizing ring 71, the fourth synchronizing ring 634 with the first synchronizing ring 623, and the second synchronizing ring 624 with the third synchronizing ring 633 smoother.

[0032] Limiting components 13 are collectively disposed on the sixth synchronous ring 72, the first synchronous ring 623, and the second synchronous ring 624. The number of limiting components 13 is equal to the number of limiting through holes 12, and their positions correspond one-to-one. Each limiting component 13 includes a connecting block 131 and an arc-shaped sliding rod 132. The connecting block 131 is slidably disposed within the limiting through hole 12. The arc-shaped sliding rod 132 is fixed within the limiting through hole 12 and slidably engages with the connecting block 131. The connecting block 131 on the first synchronous ring 623 is fixed to the third gear 621, and the connecting blocks 131 on the sixth synchronous ring 72 and the second synchronous ring 624 are both fixed to the fourth gear 622. The limiting components 13 ensure that when the fifth synchronous ring 71, the third synchronous ring 623, and the fourth synchronous ring 624 rotate, power is transmitted to the first synchronous ring 623, the sixth synchronous ring 72, and the second synchronous ring 624, respectively.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
