Description

Technical Field

[0001] The invention relates to the technical field of winding machines, and in particular to a vertical winding machine for main cable strands. Background Art

[0002] The main cable strand is an important part of the suspension bridge, used to connect the main tower and anchor of the bridge, and bear the main load of the bridge. Since the main cable strand is prefabricated into strands in the factory, it needs to be coiled and transported to the erection site. In order to facilitate transportation, it is usually wound in a vertical reel.

[0003] In the prior art, since the cable strands are long and heavy, it is easy for the cable strands to be not tensioned during the winding process. If the cable strands are not tensioned during winding, wire jumps may occur during winding, which not only affects the stability of winding, but also poses a safety problem. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a vertical reel machine for a main cable strand, which can tension the cable strand when winding it.

[0005] In order to achieve the above-mentioned object, the present invention is implemented by the following technical solutions: a vertical reel machine for main cable strands, comprising a base, a reel assembly and a drive assembly;

[0006] The reel assembly comprises a turntable, a vertical shaft and a telescopic shoe, wherein the turntable is rotatably arranged on a base, the vertical shaft is arranged on the turntable, and a plurality of telescopic shoes are circumferentially distributed on the vertical shaft and can move radially along the vertical shaft;

[0007] The driving assembly comprises a driving motor, and the driving motor is arranged in the base and can drive the turntable to rotate.

[0008] The drive motor drives the turntable and the vertical shaft to rotate, thereby driving multiple telescopic shoes to move circumferentially to reel in the cable strands. When the cable strands are loose, the telescopic shoes are moved radially outward along the vertical shaft to expand the inner diameter of the reel, thereby tightening the cable strands.

[0009] The above-mentioned vertical reel machine for main cable strands has the beneficial effect that the inner diameter of the reel is increased by the telescopic shoe, so that the cable strand can be tensioned on the telescopic shoe, thereby improving the safety and stability of the cable strand when the cable is released.

[0010] Furthermore, the telescopic tile comprises a tile and a telescopic arm, a plurality of the tiles are arranged around the circumference of the vertical shaft, and all of the tiles are connected to the vertical shaft through the telescopic arm.

[0011] By extending and retracting the telescopic arm, the tile can be driven to move relative to the vertical shaft, thereby adjusting the inner diameter of the roll.

[0012] Furthermore, the vertical shaft is provided with a plurality of slots opened in the radial direction around the circumference, one end of the telescopic arm is connected to the tile, and the other end is slidably plugged into the slot and is located in the vertical shaft, and one end of the telescopic arm located in the cavity is provided with helical teeth, and a rotatable pawl is provided on the inner wall of the cavity, and the pawl can move the helical teeth;

[0013] The vertical shaft has a cavity inside, a rotatable wheel is arranged in the cavity, and the wheel can push the end of the telescopic arm to move outwards. A reduction motor is arranged on the top of the vertical shaft, and the reduction motor is connected to the wheel.

[0014] The reduction motor drives the wheel to rotate, so that the wheel can push the end of one of the telescopic arms outward. When the helical teeth on the telescopic arm move outward, they push the pawl, so that it can slide outward in the slot, expand the inner diameter to tighten the cable strand. After the pawl is reset, it will abut against the helical teeth, so that the telescopic arm cannot move inward, achieving the effect of only being able to move in one direction.

[0015] Furthermore, the wheel disc is a cam.

[0016] The cam-shaped wheel disc can push the telescopic arm outward through the raised portion, and then the telescopic arm cannot be retracted inward under the cooperation of the ratchet pawl and the oblique tooth groove.

[0017] Furthermore, the top and bottom of the tile are both connected with telescopic arms, and two wheel discs are axially arranged in the cavity, corresponding to the telescopic arms at the top and bottom respectively.

[0018] The top and bottom of the tile are connected by telescopic arms, which can improve the overall stability of the device.

[0019] Furthermore, the driving assembly further comprises a driving gear and a driven gear, two driving motors are symmetrically provided and both are connected with a driving gear, the turntable is fixedly provided with a driven gear, and the driving gear is meshed with the driven gear.

[0020] The motor drives the driven gear to rotate through the driving gear, thereby driving the turntable to rotate and reeling the cable strands. The two motors can achieve good driving and braking effects.

[0021] Furthermore, a telescopic rod is provided on the base, a height adjustment block is provided on the top of the telescopic rod, and a through hole through which the cable strand can pass is provided on the height adjustment block.

[0022] By extending and retracting the telescopic rod, the height through which the cable strand passes can be adjusted, so that the reeling height on the telescopic shoe can be adjusted according to the progress of reeling.

[0023] Furthermore, a slide groove is provided on the outer wall of the turntable in the circumferential direction, and the slide groove includes a horizontal section and a lower convex section, the horizontal section is horizontally arranged in the circumferential direction, the lower convex section protrudes downward in an arc shape, and both ends are respectively connected to the horizontal section, a slide rod capable of vertical movement is provided in the base, and a slider slidably connected to the slide groove is provided on the slide rod;

[0024] The telescopic rod is a multi-section sleeve structure, and the outer wall of each section is provided with two oblique teeth. The sliding rod is provided with two rotatable ratchets, and the two ratchets can push the two oblique teeth downward.

[0025] When the turntable moves in the circumferential direction, each rotation can drive the slide bar to move downward and then upward through the lower convex section. When the slide bar moves downward, it can push the oblique tooth 2 downward through the ratchet 2, so that the telescopic rod shrinks downward, thereby achieving the effect of height adjustment.

[0026] Furthermore, a limiting sleeve is provided in the base, and the sliding rod is slidably inserted in the limiting sleeve.

[0027] The limiting sleeve can limit the sliding rod to move only in the vertical direction.

[0028] Furthermore, a cylinder is provided on the base, and the second bevel gear is laterally inserted on the telescopic rod, and the cylinder can push the second bevel gear to separate from the telescopic rod.

[0029] By pushing the second bevel gear to separate from the telescopic rod through the cylinder, interference between the second bevel gear and the sleeve can be avoided so that the telescopic rod can be compressed downward. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0040] See also Figures 1 to 4 The present invention provides a vertical reel machine for a main cable strand, comprising a base 10, a reel assembly 20 and a drive assembly 30. Driven by the drive assembly 30, the cable strand can be reeled up through the reel assembly 20.

[0041] Specifically, the reel assembly 20 includes a turntable 21, a vertical shaft 22 and a telescopic shoe 23. The turntable 21 is rotatably disposed on the base 10, the vertical shaft 22 is fixedly disposed on the turntable 21, and a plurality of telescopic shoes 23 are circumferentially distributed on the vertical shaft 22 and can move radially along the vertical shaft 22. The drive assembly 30 includes a drive motor 31, which is disposed in the base 10 and connected to the turntable 21 to drive the turntable 21 to rotate.

[0042] The rotating disk 21 and the vertical shaft 22 are driven to rotate by the driving motor 31, thereby driving the multiple telescopic shoes 23 to move circumferentially, so that the cable strands can be wound up. When the cable strands are loose, the telescopic shoes 23 can be moved outward along the radial direction of the vertical shaft 22 to expand the inner diameter of the winding, so that the cable strands are tensioned on the telescopic shoes 23, thereby improving the safety and stability of subsequent cable laying.

[0043] Specifically, the telescopic tile 23 includes a tile 231 and a telescopic arm 232. A plurality of tiles 231 are arranged around the circumference of the vertical shaft 22, and all of them are connected to the vertical shaft 22 through the telescopic arm 232. The vertical shaft 22 has a cavity inside, and a plurality of slots are opened in the radial direction and connected to the cavity on the outer wall around the circumference. One end of the telescopic arm 232 is connected to the tile 231, and the other end is slidably inserted into the cavity through the slot, and one end located in the cavity is provided with a bevel tooth 233, and a rotatable ratchet 223 is provided on the inner wall of the cavity, and the ratchet 223 can move the bevel tooth 233. A rotatable wheel 221 is also provided in the cavity, and the wheel 221 can push the end of the telescopic arm 232 to move outward. A reduction motor 222 is provided at the top of the vertical shaft 22, and the reduction motor 222 is connected to the wheel 221.

[0044] By extending and retracting the telescopic arm 232, the tile 231 can be driven to move relative to the vertical shaft 22, thereby adjusting the inner diameter of the winding, and expanding it to tighten the cable strand. The reduction motor 222 drives the wheel 221 to rotate, so that the wheel 221 pushes the end of the telescopic arm 232 to push it outward. When the helical teeth 233 on the telescopic arm 232 move outward, they push the pawl 223, so that it can slide outward in the slot, expand the inner diameter to tighten the cable strand. After the pawl 223 is reset, it will fall on the other side of the helical teeth 233 and cannot continue to rotate, so that the telescopic arm 232 cannot move inward. Figure 2 The left telescopic arm is shown to prevent the cable strand from loosening. The ratchet 223 can be arranged above the telescopic arm 232 and reset under the action of gravity, or it can be arranged on the side and rotatably connected to the inner wall using a spring hinge and reset under the action of elastic force.

[0045] In this embodiment, the wheel disc 221 is in the shape of a cam, and whenever there is a slack condition, one of the telescopic arms 232 can be pushed by rotating the wheel disc 221 to tighten the cable strand. The cam-shaped wheel disc 221 can push the telescopic arm 232 outward through the raised portion, and then the telescopic arm 232 cannot be retracted inward under the cooperation of the pawl 223 and the groove of the oblique tooth 233.

[0046] In addition, in this embodiment, the top and bottom of the tile 231 are connected to telescopic arms 232, and two wheels 221 are axially arranged in the cavity, respectively corresponding to the top and bottom telescopic arms 232. The two sets of telescopic arms 232 at the top and bottom can improve the overall stability of the device.

[0047] Specifically, the driving assembly 30 further includes a driving gear 32 and a driven gear 211. Two driving motors 31 are symmetrically provided, and both are connected to the driving gear 32. The rotating disk 21 is fixed with the driven gear 211, and the driving gear 32 is meshed with the driven gear 211. When started, the motor drives the driven gear 211 to rotate through the driving gear 32, and the rotating disk 21 can be driven to rotate to reel in the rope strands. The two motors can achieve good driving and braking effects.

[0048] The base 10 is also provided with a telescopic rod 11, and a height adjustment block 111 is provided at the top of the telescopic rod 11. A through hole for the cable strand to pass through is provided on the height adjustment block 111. By extending and retracting the telescopic rod 11, the height through which the cable strand passes can be adjusted, so as to adjust the winding height on the telescopic shoe 23 according to the progress of winding.

[0049] The outer wall of the rotating disk 21 is provided with a slide groove 212 around the circumference, and the slide groove 212 includes a horizontal section and a lower convex section. The horizontal section is horizontally arranged around the circumference, and the lower convex section protrudes downward in an arc shape, and the two ends are respectively connected to the horizontal section. The base 10 is provided with a slide bar 12 and a limit sleeve 13. The slide bar 12 is slidably inserted in the limit sleeve 13 and can move in the vertical direction. The slide bar 12 is provided with a slider 121 slidably connected to the slide groove 212. The telescopic rod 11 is a multi-section sleeve structure, and the outer wall of each section is provided with a second helical tooth 112, and the friction between the sleeves is relatively large. The slide bar 12 is provided with a rotatable second ratchet 122, and the second ratchet 122 can push the second helical tooth 112 downward.

[0050] When the rotating disk 21 moves in the circumferential direction, each rotation can drive the sliding rod 12 to move downward and then upward through the lower convex section. When the sliding rod 12 moves downward, the second slanted tooth 112 can be pushed downward by the second ratchet 122, so that the telescopic rod 11 is partially retracted downward, thereby achieving the effect of adjusting the height of the cable strand. When the sliding rod 12 moves upward, the second slanted tooth 112 can push the second ratchet 122 to rotate, so as to avoid lifting the telescopic rod 11.

[0051] In this embodiment, a cylinder 14 is further provided on the base, and a second helical tooth 112 is inserted transversely on the outer wall of each sleeve of the telescopic rod 11. Figure 4 As shown, it is a cross-sectional view of one of the sleeves. When the second bevel gear 112 falls with the sleeve, the cylinder 14 extends to push the second bevel gear 112 away from the telescopic rod 11 to avoid interference.

[0052] The working principle of the vertical reel machine for the main cable strand is as follows: the driving motor 31 drives the driving gear 32 to rotate, driving the driven gear 211, the turntable 21 and the vertical shaft 22 to rotate, thereby driving the multiple telescopic shoes 23 to move circumferentially to reel the cable strand. At regular intervals, the reduction motor 222 is started to drive the wheel 221 to rotate, pushing the telescopic arm 232 to extend outward, so that the inner diameter of the reel can be expanded, thereby tightening the cable strand. During the reeling process, the turntable 21 drives the slide bar 12 to move up and down through the slide slot 212, and with the cooperation of the ratchet 122 and the bevel gear 112, the telescopic rod 11 is gradually compressed downward, so that the height adjustment block 111 can adjust the reeling point of the cable strand downward.

[0053] By using the vertical reel machine for the main cable strand, the inner diameter of the reel can be increased by moving the telescopic shoe outward, thereby tensioning the cable strand on the telescopic shoe, thereby improving the safety and stability of the subsequent cable strand during the cable release. The reeling position of the cable strand can also be gradually adjusted downward during the reeling process.
