Description

Technical Field

[0001] The present invention relates to the technical field of main cable installation devices for suspension bridges, and in particular to an AS aerial spinning pay-off machine. Background Art

[0002] The AS method, known as the aerial spinning method, involves a winch pulling two spinning wheels in a reciprocating motion. Each spinning wheel pulls four steel wires, requiring four spools. This means that if two strands are spun simultaneously, the two spinning wheels pull eight wires, requiring eight pay-offs. Main cable strands weigh tens or even hundreds of tons, and each spool can wind 6 to 8 tons of wire. Therefore, the pay-offs often require multiple replacements of spools to complete the installation of a single strand. To replace a spool, the spool is typically removed from the pay-off, and the full spool is then reinstalled on the pay-off. Using a crimping machine and crimping sleeves, the wire ends of the full spool are connected to the already installed wire roots, allowing the cable to continue.

[0003] Existing pay-off machines require downtime when replacing spools. Currently, each spool replacement typically takes 20 to 30 minutes, and replacing eight spools in succession can take at least 160 minutes. This significantly impacts the efficiency of main cable strand installation and increases project construction costs. Therefore, improving the efficiency of main cable strand installation and reducing project construction costs during spool replacements is a pressing technical challenge. Summary of the Invention

[0039] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0040] Figure 1 FIG. 1 is a front view of an AS aerial spinning pay-off machine according to an embodiment of the present invention. Figure 2 FIG. 1 is a top view of an AS aerial spinning pay-off machine according to an embodiment of the present invention, Figure 1 and Figure 2 As shown, the AS aerial spinning pay-off machine at least includes a frame 100, a driving component 210, a first clutch 231, a second clutch 232, a first spool 310, a second spool 320, a first sliding shaft 241, a second sliding shaft 242, a first active pushing mechanism and a second active pushing mechanism.

[0041] The driving component 210 is arranged on the frame 100; the input end of the first clutch 231 and the input end of the second clutch 232 are both connected to the output end of the driving component 210, and the first clutch 231 and the second clutch 232 are configured so that when one of them is engaged, the other is disengaged; the first spool 310 and the second spool 320 are respectively connected to the output end of the first clutch 231 and the output end of the second clutch 232, and the first spool 310 rotates when the first clutch 231 is engaged, and the second spool 320 rotates when the second clutch 232 is engaged. The wheel 320 rotates; the first sliding shaft 241 and the second sliding shaft 242 are both arranged on the frame 100, the first sliding shaft 241 is located between the first I-shaped wheel 310 and the output end of the first clutch 231, and the second sliding shaft 242 is located between the second I-shaped wheel 320 and the output end of the second clutch 232; the first active pushing mechanism and the second active pushing mechanism are both arranged on the frame 100, and the first active pushing mechanism and the second active pushing mechanism are respectively used to drive the first sliding shaft 241 and the second sliding shaft 242 to move.

[0042] In the above embodiment, the frame 100 is used to support the driving component 210, the first clutch 231, the second clutch 232, the first spool 310, the second spool 320, the first sliding shaft 241, the second sliding shaft 242, the first active pushing mechanism and the second active pushing mechanism. When the pay-off machine is working, the frame 100 can be specifically set on the ground. Figure 1 As shown, the frame 100 may specifically include a base plate and a plurality of support seats; the driving component 210 may be detachably connected to the frame 100, and both clutches are connected to the output end of the driving component 210 via a coupling 220. The clutch is arranged between the spool and the driving component 210, and is used to separate or engage the support shaft of the spool and the output shaft of the driving component 210; when the clutch engages the support shaft of the spool and the output shaft of the driving component 210, the corresponding spool can be driven to rotate by the driving component 210, and when the clutch separates the support shaft of the spool and the output shaft of the driving component 210, the spool stops rotating, and the stopped spool can be replaced at this time. Specifically, when the main cable strand is being installed, if the wire winding on the first spool 310 is completely unwound, the first clutch 231 is disengaged and the second clutch 232 is engaged, so that the full second spool 320 starts working, and accordingly the empty first spool 310 can be replaced with a full spool; it can be seen that the pay-off machine of the present application does not need to be shut down when replacing the spools, and the second spool 320 can work simultaneously while the first spool 310 is being replaced, thereby improving the efficiency of the main cable strand installation and thereby reducing the project construction cost.

[0043] like Figure 1 As shown, the first spool 310 and the second spool 320 are supported by a support seat of the frame 100. The first sliding shaft 241 and the second sliding shaft 242 are both rotatably supported on the frame 100 via bearings. The first sliding shaft 241 and the second sliding shaft 242 can move along the axial direction of the spools under the drive of the first active thrust mechanism and the second active thrust mechanism, respectively. For ease of description, the first sliding shaft 241 and the second sliding shaft 242 are collectively referred to as sliding shafts, the first spool 310 and the second spool 320 are collectively referred to as spools, and the first active thrust mechanism and the second active thrust mechanism are collectively referred to as active thrust mechanisms. However, it should be noted that the sliding shaft and active thrust mechanism corresponding to the first spool 310 should be referred to as the first spool 310 and the first active thrust mechanism.

[0044] Specifically, the slip shaft acts as a transmission shaft between the clutch and the spool. When the slip shaft engages the spool, the spool rotates synchronously with the slip shaft, indicating the spool is in operation. When the spool needs to be replaced, the slip shaft separates from the spool, preventing rotation. The engagement and disengagement of the slip shaft and spool are driven by an active thrust mechanism. For example, the active thrust mechanism drives the slip shaft toward the spool, allowing the end of the slip shaft to mate with the spool, thereby engaging the slip shaft and spool. The active thrust mechanism drives the slip shaft away from the spool, separating the slip shaft and spool.

[0045] Furthermore, the pay-off machine includes a first transmission mechanism and a second transmission mechanism, wherein the first transmission mechanism is located between the first sliding shaft 241 and the first clutch 231, and the second transmission mechanism is located between the second sliding shaft 242 and the second clutch 232. In this embodiment, when the clutch is engaged, the driving component 210 drives the sliding shaft to rotate through the transmission mechanism, and the sliding shaft then drives the spool to rotate.

[0046] For example, Figure 5 As shown, the first transmission mechanism and the second transmission mechanism are both gear mechanisms, and the support shaft of the driving gear 251 is engaged or disengaged with the output shaft of the driving component 210 through a clutch; the support shaft of the driving gear 251 is rotatably supported on the frame 100 through a bearing, and when the clutch is engaged, the driving gear 251 rotates synchronously with the output shaft of the driving component 210. In order to make the first sliding shaft 241 and the second sliding shaft 242 both rotatable and axially movable, the first sliding shaft 241 and the second sliding shaft 242 can be set as spline shafts; and the wire unwinding machine can also include a first spline sleeve 261 and a second spline sleeve 262, the first sliding shaft 241 is located in the shaft hole of the first spline sleeve 261, and the second sliding shaft 242 is located in the shaft hole of the second spline sleeve 262; in this embodiment, the sliding shaft is similar to a spline structure, and the first sliding shaft and the second sliding shaft can not only move axially in the shaft holes of the first spline sleeve 261 and the second spline sleeve 262 respectively, but also rotate synchronously with the first spline sleeve 261 and the second spline sleeve 262 respectively. Specifically, the driven gear 252 of the first transmission mechanism and the driven gear 252 of the second transmission mechanism are connected to the first spline sleeve 261 and the second spline sleeve 262 respectively, and at this time the spline sleeve and the corresponding side driven gear 252 rotate synchronously.

[0047] In some embodiments of the present invention, the first active pushing mechanism and / or the second active pushing mechanism include a linear motion mechanism and a pushing drive component. The linear motion mechanism is configured to convert the rotational motion of the pushing drive component into linear motion of the first sliding shaft 241 or the second sliding shaft 242. In this embodiment, the pushing drive component rotates, and the linear motion mechanism converts the rotational motion into linear motion, so that the sliding shaft and the linear motion mechanism move synchronously.

[0048] For example, the linear motion mechanism includes a push rod 410 and a nut 420, wherein the nut 420 is provided on the frame 100, and the push rod 410 is connected to the push driving component. Figure 5 As shown, the nut 420 can be rotatably supported on the frame 100 by a bearing, and the nut 420 is driven by a push drive component, which can be a handle. In this case, the nut 420 can be rotated by turning the handle; the push screw 410 can be moved horizontally as the nut 420 rotates. Figure 5 In the embodiment, when the push screw 410 moves to the left, it pushes the sliding shaft toward the spool, gradually engaging the spool with the spool. When the push screw 410 moves to the right, it drives the sliding shaft to the right, gradually separating the sliding shaft from the spool. It will be understood that the use of a screw-nut structure as the linear motion mechanism in this embodiment is merely an example. In other embodiments, other mechanisms that convert rotational motion into linear motion, such as a rack and pinion mechanism, may also be used. Furthermore, the use of a handle as the push drive component in this embodiment is merely an example; a motor, etc., may also be used.

[0049] In some embodiments of the present invention, a connecting assembly is provided at the end of the push screw 410, and the connecting assembly includes a sleeve 411 and an end cap 422. The first end of the sleeve 411 is connected to the push screw 410, and the end cap 422 is disposed in a groove of the sleeve 411 and located at the second end of the sleeve 411. The end cap 422 is detachably connected to the sleeve 411, and the end cap 422 is connected to the first sliding shaft 241 or the second sliding shaft 242. The connecting assembly is used to achieve the connection between the push screw 410 and the sliding shaft. Since the sliding shaft rotates synchronously with the driven gear 252 of the transmission mechanism, and the push screw 410 only moves linearly under the rotational drive of the nut 420, the connecting assembly should not only ensure the connection between the push screw 410 and the sliding shaft, but also enable the sliding shaft to rotate relative to the push screw 410. In this embodiment, the sleeve 411 is located at the left end of the push screw 410. The groove of the sleeve 411 is a structure with an open left portion. The groove can be used as a accommodating space for the end of the sliding shaft. That is, when the push screw 410 and the sliding shaft are connected based on the connection assembly, the first end of the sleeve 411 ( Figure 5The right end wall of the sleeve 411 in the middle is connected to the left end of the push screw 410, and then the end cover 422 is connected to the right end of the sliding shaft, and further the end cover 422 is connected to the sleeve 411 by a detachable connection, thereby realizing the connection between the push screw 410 and the sliding shaft; wherein the detachable connection between the end cover 422 and the sleeve 411 can be specifically a screw or bolt connection.

[0050] In some embodiments of the present invention, the end cap 422 has an axial hole, and the sliding shaft extends from the axial hole to the groove of the sleeve 411. The first sliding shaft 241 and the second sliding shaft 242 have C-shaped grooves at their ends close to the end cap 422, and the C-shaped grooves match the axial hole. Figure 5 As shown, the right end of the sliding shaft has an annular groove (C-shaped groove), and the end cap 422 has a corresponding axial hole. At this time, the axial end corresponding to the annular groove of the sliding shaft is located in the axial hole of the end cap 422. In this embodiment, in order to facilitate the disassembly and assembly between the sliding shaft and the end cap 422, the shaft shoulder at the right end of the annular groove can be set as a detachable structure, such as by using a threaded connection. At this time, when connecting the end cap 422 to the sliding shaft, the detachable shaft shoulder can be first removed from the shaft segment to which the annular groove belongs, and the shaft segment to which the annular groove of the sliding shaft belongs is installed into the central axial hole of the end cap 422. Then, the detachable shaft shoulder is further installed on the shaft segment to which the annular groove belongs. That is, the detachable shaft shoulder in this embodiment achieves the effect of axial positioning of the sliding shaft, and the detachable shaft shoulder in this embodiment is similar to the structure of a nut. In addition, other components such as shaft segment retaining rings and shaft end baffles can be used between the sliding shaft and the end cap 422 to achieve its axial positioning.

[0051] In addition, since the sliding shaft can rotate relative to the push rod 410, in order to avoid friction between the wall of the shaft hole on the end cover 422 and the C-shaped groove on the sliding shaft, a thrust ball bearing is further provided between the sleeve 411 and the push rod 410. Through the above embodiment, it can be found that the active push mechanism of the present application has a simple structure. It adopts the principle of a shift fork structure, that is, the push rod 410 can push and pull the sliding shaft to move left or right, and the push rod 410 and the sliding shaft are connected by a ring groove and a thrust ball bearing, which ensures that the push rod 410 does not rotate when the sliding shaft rotates.

[0052] In some embodiments of the present invention, the wire unwinding machine includes a first passive pushing mechanism and a second passive pushing mechanism, the first passive pushing mechanism and the second passive pushing mechanism include a handle 510, a push rod 520 and a support block 530, the handle 510 and the support block 530 are respectively arranged at both ends of the push rod 520, a bearing is provided between the support block 530 and the push rod 520, and the support block 530 is used to combine with or separate from the I-shaped wheel under the pushing action of the push rod 520.

[0053] like Figure 6 As shown, the passive pushing mechanism is similar to the active pushing mechanism and includes a handle 510 and a push rod 520. The push rod 520 converts the rotational motion of the handle 510 into linear motion. That is, when the handle 510 is rotated, the push rod 520 moves linearly toward or away from the spool. A bearing is provided between the support block 530 at the end of the push rod 520 and the push rod 520 so that the support block 530 can rotate relative to the push rod 520. Figure 6 The state shown in FIG is a state where the support block 530 is separated from the spool.

[0054] Furthermore, the driving component 210 is a dual-output shaft motor, and the first spool 310 and the second spool 320 are symmetrically arranged at both ends of the dual-output shaft motor. Figure 2 and Figure 3 As can be seen from the figure, the dual-output shaft motor is specifically located in the middle of the frame 100, and the first spool 310 and the second spool 320 are symmetrically arranged at both ends of the dual-output shaft motor.

[0055] Through the above embodiments, it can be found that the AS aerial spinning pay-off machine of the present application includes a first clutch, a second clutch, a first spool and a second spool, and the first spool and the second spool are respectively connected to the output end of the first clutch and the output end of the second clutch, and the first clutch and the second clutch are configured so that one of them is engaged and the other is disengaged. Therefore, when one of the spools is replaced in the present application, the other spool can work, so that the pay-off machine does not need to be shut down during the spool replacement process. Therefore, the present application improves the work efficiency of the main cable strand installation and reduces the project construction cost.

[0056] In order to better explain the AS aerial spinning pay-off machine of this application, the following reference Figure 7 and Figure 8 The working process of the AS aerial spinning pay-off machine of the present application is described in detail.

[0057] like Figure 7As shown, when the drive motor is operating, the active and passive pushing mechanisms of spool 1 both push into the spool and engage with it. At this point, clutch 1 is energized, and spool 1 will release wire normally. At this point, clutch 2 is de-energized, and spool 2 can be replaced. Clutch 1 and clutch 2 are always in a complementary state: when clutch 1 is energized, clutch 2 is de-energized; when clutch 1 is de-energized, clutch 2 is energized. Similarly, when clutch 2 is energized, the active and passive pushing mechanisms of spool 2 both push into the spool and engage with it. Spool 2 will release wire normally, and spool 1 can be replaced with a full-disc spool. Furthermore, when the drive motor stops, clutch 1 and clutch 2 are both de-energized.

[0058] When spool 1 is operating, spool 2 is stationary; when spool 2 is operating, spool 1 is stationary. The clutch can be a magnetic powder clutch, a superior automatic control element. It uses magnetic powder as its working medium and excitation current as its control mechanism to achieve braking torque or torque transmission. Its output torque exhibits a good linear relationship with the excitation current, and it offers advantages such as fast response and a simple structure. In this embodiment, when the drive motor is operating, the clutch is engaged when energized and disengaged when de-energized.

[0059] from Figure 8 It can be seen that the reducer of the drive motor has a dual output shaft, and the two output shafts are respectively connected to clutch 1 and clutch 2 through a coupling; the clutch is connected to the driving gear through the coupling, the driving gear drives the passive gear to rotate, the passive gear is connected to the spline sleeve through a flat key, the spline sleeve drives the spline shaft to rotate through the spline, and the spline shaft drives the I-wheel to rotate, thereby realizing active wire feeding.

[0060] In addition, after spinning a strand, the spool with an empty reel needs to be replaced with a full reel several times. Therefore, in the present application, when replacing the spool, the sliding shaft needs to be withdrawn from the spool to separate the end of the sliding shaft from the spool. When the spool is unwinding, the sliding shaft needs to be pushed into the spool with the help of an active pushing mechanism, so that the driving mechanism drives the spool to unwind through the sliding shaft. Specifically, when the sliding shaft is pushed into the spool, the pushing screw is rotated, and the pushing screw moves leftward, pushing the sliding shaft leftward, so that the sliding shaft is placed in the spool, and the sliding shaft can drive the spool to rotate. When replacing the spool, the sliding shaft needs to move right. At this time, the pushing screw can be rotated in the opposite direction, and the connecting assembly on the pushing screw pulls the sliding shaft to move rightward, thereby separating the sliding shaft from the spool.

[0061] The AS aerial spinning pay-off machine disclosed in the above embodiment of the present application saves the time for replacing the I-spools. Each replacement of the I-spools (8 pieces) can save about three hours, thereby improving the spinning efficiency and saving production costs. In addition, the two I-spools are driven by a set of drive systems, which saves equipment costs, reduces the difficulty of operation and the possibility of misoperation. When the AS aerial spinning pay-off machine of the present application is working, the two clutches are always in opposite working states, and the magnetic powder clutch adopts PLC control, which improves intelligence and automation.

[0062] In the present invention, features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, and / or combined with or replace features of other embodiments.

[0063] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations to the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
