Description

Technical Field

[0001] The invention belongs to the field of cable placement, and in particular relates to an all-round adjustable pay-off rack. Background Art

[0002] Pay-off equipment is a common device used in cable placement. Traditional pay-off equipment is equipped with multiple pay-off wheels, which selectively pay out one cable and constantly change the pay-off direction. Existing pay-off equipment lacks a structure that can adapt to the changing pay-off direction.

[0003] In addition, because the pay-off equipment has multiple pay-off reels, which also serve as take-up reels, the multiple take-up reels rely on inefficient manual methods to take up the line because they are not driven. If all the take-up reels are to be taken up uniformly or selectively, a drive motor must be added to each take-up reel, which will increase the equipment cost.

[0004] The present invention designs a fully adjustable pay-off stand to solve the above problems. Summary of the Invention

[0005] In order to solve the above-mentioned defects in the prior art, the present invention discloses a fully adjustable pay-off stand, which is realized by adopting the following technical solutions.

[0006] A fully adjustable pay-off frame comprises an outer bracket, an inner bracket and a winding and releasing mechanism, wherein the cylindrical outer bracket is rotatably matched with the cylindrical inner bracket, and the inner bracket is equipped with two equal layers of winding and releasing mechanisms with the layers staggered around the central axis.

[0007] The winding mechanism includes a door frame, a winding wheel, a rotating shaft A, a rotating shaft B, a disk A, a ring B, an insertion rod A, a ring C, a spring B, a ring D, a rotating shaft C, a disk B, a ring F, an insertion rod B, a spring C, a nut, a rack, a motor A, and a motor B. A detachable winding wheel for winding and placing cables is installed in the door frame fixed to the inner bracket. The two rotating seats on the outer side of the door frame are rotatably matched with the rotating shaft B and the rotating shaft C with the same central axis. The rotating shaft C is driven by the motor B on the inner bracket, and the rotating shaft B is in transmission cooperation with the rotating shaft A where the winding wheel is located; a ring is nested and slidably on the rotating shaft B. B, several insertion rods A at one end of the ring sleeve B correspond one to one with the slots A on the disk A at the end of the rotating shaft B and the disk B at the end of the rotating shaft B; a ring sleeve C is nested and slidably mounted on the ring sleeve B and is nested with a spring B for resetting the relative movement of the two; a ring sleeve D that moves axially is rotatably mounted on the ring sleeve C, and the rack on the ring sleeve D is engaged with the gear D driven by the motor A on the inner bracket; a ring sleeve F is nested and slidably mounted on the rotating shaft C, and several insertion rods B at one end of the ring sleeve F correspond one to one with the slots B on the disk A and the disk B; a nut connected to the ring sleeve F through the spring C is screwed on the rotating shaft C.

[0008] As a further improvement of the present technology, the gantry is rotatably fitted with two coaxial rotating pins, each of which is nested with a ring sleeve A that slides axially with the rotating shaft A where the winding wheel is located, and is nested with a spring A for resetting the ring sleeve A.

[0009] As a further improvement of the present technology, a gear B is mounted on the rotating shaft B, and the gear B is engaged with the gear A mounted on the corresponding side rotating pin.

[0010] As a further improvement of the present technology, the gear E installed on the shaft where the gear D is located is meshed with the gear F on the inner bracket, and the gear G installed on the shaft where the gear F is located is meshed with the ring gear A rotating around the central axis in the four guide sleeves B fixed on the inner bracket; the ring gear A is meshed with the gear H on the output shaft of the motor A.

[0011] As a further improvement of this technology, a gear C is installed on the rotating shaft C, and the gear C is engaged with the ring gear B rotating around the central axis in the four guide sleeves A fixed on the inner bracket; the ring gear B is engaged with the gear I on the output shaft of the motor B.

[0012] As a further improvement of the present technology, the gantry is provided with a guide wheel B for guiding the cables on the corresponding winding wheel to pass through the circular groove B at the upper end of the inner bracket and the circular groove A at the upper end of the outer bracket from bottom to top; the edge of the circular groove B at the upper end of the inner bracket is provided with a number of guide wheels A for corresponding one-to-one with the cables on the winding wheel and guiding the corresponding cables to pass through the circular groove A and the circular groove B vertically.

[0013] Compared with traditional winding and unwinding equipment, the two-layer winding wheel in the present invention can adapt to the change of unwinding direction by rotating the inner bracket relative to the outer bracket when used as an unwinding wheel, thereby meeting the unwinding demand of constantly changing unwinding direction.

[0014] The two-layer winding wheels of the present invention, when used as take-up wheels, can all be driven in conjunction with each other under the drive of motor A and can achieve unified line take-up under the drive of motor B. The present invention can also selectively establish a transmission connection between any number of winding wheels under the drive of motor A, and selectively take-up the winding wheels that have already been driven by motor B. Whether all winding wheels are taken up in unison or some winding wheels are freely selected for selective take-up, only motor A and motor B are used for driving, thereby achieving unified or selective line take-up of the two-layer winding wheels while ensuring low cost, high efficiency, and strong practical effect.

[0015] The winding wheel in the winding and releasing mechanism of the present invention can be disassembled and assembled according to actual needs, and the driving energy consumption of motor A and motor B can be reduced when the winding wheel does not need to wind and release the cable.

[0016] The invention has a simple structure and good use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The accompanying drawings are schematic diagrams of the present invention to facilitate understanding of the structural operation principle. The specific product structure and proportional dimensions can be determined according to the use environment and conventional technology.

The two rotating seats 24 on the outer side of the door frame 12 are rotatably matched with the rotating shaft B25 and the rotating shaft C40 with the same central axis. The rotating shaft C40 is driven by the motor B61 on the inner bracket 6, and the rotating shaft B25 is in transmission cooperation with the rotating shaft A21 where the winding wheel 20 is located; Figure 7 、 9 As shown in FIG. 10 , a sleeve B31 is nested and slidably mounted on the shaft B25. A plurality of insert rods A35 at one end of the sleeve B31 correspond one-to-one with the end disc A27 of the shaft B25 and the slots A28 on the end disc B42 of the shaft B25. A sleeve C36 is nested and slidably mounted on the sleeve B31 and a spring B37 is nested therein to reset the relative motion between the two. Figure 4 、 7 As shown, the ring sleeve C36 is rotatably matched with the ring sleeve D38 that moves axially, and the rack 50 on the ring sleeve D38 is engaged with the gear D52 driven by the motor A58 on the inner bracket 6; Figure 7 、 9 As shown in Figure 10, a ring sleeve F43 is nested and slidably mounted on the shaft C40, and a plurality of rods B45 at one end of the ring sleeve F43 correspond one-to-one with the slots B29 on the disc A27 and the disc B42; a nut 47 connected to the ring sleeve F43 through a spring C46 is screwed onto the shaft C40.

[0032] like Figure 7As shown, the door frame 12 is rotatably fitted with two coaxial rotating pins 13, and each rotating pin 13 is nested with a ring sleeve A16 that axially slides with the rotating shaft A21 where the winding wheel 20 is located, and is nested with a spring A19 for resetting the ring sleeve A16.

[0033] like Figure 7 As shown, a gear B30 is mounted on the rotating shaft B25 , and the gear B30 is engaged with the gear A23 mounted on the corresponding side rotating pin 13 .

[0034] like Figure 4 As shown, the gear E53 mounted on the shaft where the gear D52 is located is meshed with the gear F54 on the inner bracket 6, and the gear G55 mounted on the shaft where the gear F54 is located is meshed with the ring gear A56 rotating around the central axis in the four guide sleeves B10 fixed on the inner bracket 6; the ring gear A56 is meshed with the gear H57 on the output shaft of the motor A58.

[0035] like Figure 4 、 7 As shown, a gear C48 is mounted on the rotating shaft C40, and the gear C48 meshes with a ring gear B59 rotating around the central axis in four guide sleeves A9 fixed on the inner bracket 6; the ring gear B59 meshes with a gear I60 on the output shaft of the motor B61.

[0036] like Figure 2 、 5 As shown in FIG6 , the door frame 12 is provided with a guide wheel B49 for guiding the cable 63 on the corresponding winding wheel 20 to pass through the circular groove B8 on the upper end of the inner bracket 6 and the circular groove A2 on the upper end of the outer bracket 1 from bottom to top; Figure 1 、 2 As shown, a plurality of guide wheels A4 are installed on the edge of the circular groove B8 at the upper end of the inner bracket 6, which correspond one-to-one with the cables 63 on the winding wheel 20 and guide the corresponding cables 63 to vertically pass through the circular grooves A2 and B8.

[0037] like Figure 2 、 5 As shown in Figures 6 and 6, the upper and lower ends of the inner bracket 6 are provided with trapezoidal guide rings 7, and the two guide rings rotate in the two trapezoidal guide grooves 3 between the outer and inner sides respectively.

[0038] like Figure 7 、 8 As shown, the inner wall of the ring sleeve A16 has two guide keys A17, and the two guide keys A17 slide in the two key grooves A15 on the rotating pin 13. The two ends of the rotating shaft A21 have two guide keys B22, and the two guide keys B22 at each end slide in the two guide keys B22 on the inner wall of the corresponding ring sleeve A16. Figure 7 、 9 As shown in FIG10 , the shaft B25 has two guide keys C26, which slide in two key grooves C33 on the inner wall of the corresponding ring sleeve B31. Figure 7 、 10 As shown in Figure 11, the inner wall of the ring sleeve C36 has two guide keys D62, and the two guide keys D62 slide in the two key grooves D34 on the outer side of the corresponding ring sleeve B31. Figure 7 、 9 As shown in Figure 10, the inner wall of the ring sleeve F43 has two guide keys E44, and the two guide keys E44 slide in the two key grooves E41 on the rotating shaft C40 respectively.

[0039] like Figure 7 As shown, spring A19 and spring C46 are compression springs, and spring B37 is a tension spring. Disc A27 and corresponding disc B42 rotate in the ring E39 on the door frame 12. Figure 4 As shown, the rack 50 slides in the guide sleeve C51 on the inner bracket 6.

[0040] The working process of the present invention is as follows: the two springs A19 on the gantry 12, where the winding wheel 20 is not mounted, are in a compressed state. The springs B37 and C46 in the winding and releasing mechanism 11 are both in a natural state. The insertion rod A35 on the annulus B31 is not inserted into the slot A28 on the corresponding disc B42. The insertion rod B45 on the annulus F43 is not inserted into the slot B29 on the corresponding disc A27. The transmission between the rotating shaft B25 and the corresponding rotating shaft C40 is disconnected.

[0041] The winding wheel 20 in the winding and releasing mechanism 11 of the present invention can be freely assembled and disassembled according to the actual number of cables 63 to be wound and released, and the process of assembling and disassembling the winding wheel 20 is as follows:

[0042] Installation process: Slide the rings A16 nested on the two rotating pins 13 on the corresponding door frame 12 axially, further compressing the springs A19 on each rotating pin 13 and aligning the end faces of each ring A16 with the end faces of the corresponding rotating pin 13. Then, align the ends of the rotating shaft A21 on which the winding wheel 20 is located with the two rotating pins 13 and release the two rings A16. Under the reset action of the corresponding springs A19, the two rings A16 slide axially and nest on the rotating shaft A21, completing the installation of the winding wheel 20 on the door frame 12.

[0043] Disassembly process: Slide the rings A16 nested on the two rotating pins 13 on the corresponding mast 12 axially. This further compresses the spring A19 on each rotating pin 13, causing the end face of each ring A16 to align with the end face of the corresponding rotating pin 13 and disengage from the rotating shaft A21 on which the winding wheel 20 is mounted. The winding wheel 20 can then be removed from the mast 12.

[0044] The process of the present invention in the pay-off process is as follows:

[0045] After the winding wheel 20 is installed on the door frame 12, the cable 63 wound on the winding wheel 20 is passed horizontally through the guide wheel B49 on the corresponding door frame 12 and the corresponding guide wheel A4 at the circular groove B8 of the inner bracket 6. The double-layer winding wheel 20 in the present invention can realize simultaneous release of wires in different directions after completion of installation.

[0046] If the direction of the pay-out needs to be changed during the pay-out process of a single cable 63 of the present invention, as the pulling direction changes, the cable 63 will drive the inner bracket 6 on which the winding and releasing mechanism 11 is installed to rotate relative to the outer bracket 1, thereby adapting to the change in the pulling direction at any time and improving the pay-out efficiency.

[0047] During the process of pulling and releasing the wire, the winding wheel 20 rotates under the pull of the cable 63. The winding wheel 20 drives the two rotating pins 13 to rotate through the corresponding rotating shaft A21. The rotating pin 13 drives the corresponding rotating shaft B25 to rotate through the gear A23 and the gear B30. The rotating shaft B25 drives the ring sleeve B31 axially sliding with it, the ring sleeve C36 axially sliding with the ring sleeve B31 and the corresponding disc A27 to rotate synchronously. The winding wheel 20 in each winding and releasing mechanism 11 can release the wire freely and independently during the wire-releasing process.

[0048] When the winding wheel 20 in the winding and releasing mechanism 11 is winding up, if it is necessary to wind up all the winding wheels 20 in the winding and releasing mechanisms 11 uniformly, then start the motor A58 at this time, and the motor A58 drives the racks 50 in the two winding and releasing mechanisms 11 belonging to the two layers to move toward each other in the vertical direction through the gear H57, the ring gear A56, the gear G55, the gear F54, the gear E53, and the gear D52. Each rack 50 drives the corresponding ring sleeve C36 rotating with it to move synchronously in the vertical direction through the corresponding ring sleeve D38. The ring sleeve C36 drives the ring sleeve B31 and the insertion rod A35 on the ring sleeve B31 to move toward the slot A28 on the corresponding disc A27 by stretching the corresponding spring B37. If the slots A28 on disk A27 and the slots A28 on the corresponding disk B42 are not initially aligned, the ring C36, through the spring B37, drives the rod A35 on the ring B31 to abut against the end surface of disk B42, further stretching the spring B37 to store energy. If the slots A28 on disk A27 and the slots A28 on the corresponding disk B42 are initially aligned, the ring C36, through the spring B37, drives the rod A35 on the ring B31 to insert into the slots A28 on disk B42, thereby establishing a transmission connection between the rotating shaft B25 and the rotating shaft C40.

[0049] Then, motor A58 is stopped and motor B61 is started. Motor B61, via gear I60 and ring gear B59, drives all gears C48 in the winding and releasing mechanism 11 to rotate. Gears C48 then drive the corresponding shafts C40 to rotate synchronously. If the insertion rod A35 in the winding and releasing mechanism 11 abuts against the end face of the corresponding disk B42, then as each shaft C40 rotates, the insertion rod A35, driven by spring B37, instantly inserts into the slot A28 on disk B42 when the slot A28 on disk B42 is aligned with the slot A28 on disk A27, completing the transmission connection between the shafts C40 and B25.

[0050] The rotating shaft C40 in the winding and releasing mechanism 11 that completes the transmission connection between the rotating shaft C40 and the rotating shaft B25 will drive the winding wheel 20 installed on the corresponding rotating shaft A21 to rotate through the corresponding disc B42, the insertion rod A35, the disc A27, the rotating shaft B25, the gear B30, the gear A23 and the rotating pin 13, and automatically rewind the cable 63, thereby improving the winding efficiency.

[0051] If only one or several winding wheels 20 in the winding and releasing mechanisms 11 need to be wound up, then the nuts 47 in the winding and releasing mechanisms 11 that need to be wound up are rotated respectively. The nut 47 compresses the corresponding spring C46 to drive the ring F43 on the corresponding rotating shaft C40 to move axially toward the disc A27.

[0052] If the slots B29 on disk A27 and the slots B29 on the corresponding disk B42 are initially aligned perfectly one-to-one, then when the insertion rod B45 on the collar F43 is inserted into the slots B29 on disk A27, the rotation of the nut 47 is stopped, thereby completing the transmission connection between the rotating shaft B25 and the corresponding rotating shaft C40 in the winding and releasing mechanism 11. If the slots B29 on disk A27 and the slots B29 on the corresponding disk B42 are not initially aligned perfectly one-to-one, the nut 47, through the spring C46, drives the insertion rod B45 on the collar F43 to abut against the end surface of disk A27, causing the spring C46 to be further compressed to store energy, and the transmission connection between the rotating shafts B25 and C40 is not completed.

[0053] Then, motor B61 is started and, through gear I60 and ring gear B59, drives all gears C48 in the winding and releasing mechanism 11 to rotate. Gears C48 then drive the corresponding shafts C40 to rotate synchronously. If the insertion rods B45 in the winding and releasing mechanism 11 abut against the end faces of the corresponding disks A27, then as each shaft C40 rotates, the insertion rods B45, driven by springs C46, instantly insert into the slots B29 on disk A27 when the slots B29 on disk A27 and the slots B29 on disk B42 are aligned one by one. This completes the transmission connection between the shafts C40 and B25.

[0054] The rotating shaft C40 in the winding and releasing mechanism 11 that completes the transmission connection between the rotating shaft C40 and the rotating shaft B25 will drive the winding wheel 20 installed on the corresponding rotating shaft A21 to rotate through the corresponding disc B42, the insertion rod B45, the disc B42, the rotating shaft B25, the gear B30, the gear A23 and the rotating pin 13, and automatically rewind the cable 63, thereby improving the winding efficiency.

[0055] The rotating shaft C40 and the rotating shaft B25 in the winding mechanism that does not need to be wound up are not connected in transmission. After the motor B61 is started, it will not drive the winding wheel 20 in these winding mechanisms to rotate and wind up the line.

[0056] As described above, the winding wheel 20 in one or several winding mechanisms can be freely and selectively taken up, so that the winding mechanism for taking up the line and the winding mechanism for continuing to pay out the line can perform their respective taking-up or paying-out operations without interfering with each other, thereby improving the efficiency of taking up and paying out the line.

[0057] When the line is taken up, the motor B61 is stopped, and the nut 47 in the winding mechanism that forms a transmission connection between the rotating shaft C40 and the rotating shaft B25 is rotated in sequence, so that the nut 47 drives the insertion rod B45 on the ring sleeve F43 to disengage from the slot B29 on the disc A27 and reset through the spring C46, thereby disconnecting the transmission connection between the rotating shaft C40 and the rotating shaft B25.

[0058] To sum up, the beneficial effects of the present invention are as follows: when used as a pay-off wheel, the two-layer winding wheel 20 of the present invention can adapt to changes in the pay-off direction by rotating the inner bracket 6 relative to the outer bracket 1, thereby meeting the pay-off requirements of constantly changing pay-off directions.

[0059] The two layers of winding wheels 20 in the present invention, when used as take-up wheels, can all be driven in conjunction with each other under the drive of motor A58 and can achieve unified take-up under the drive of motor B61. The present invention can also selectively establish a transmission connection between any of the winding wheels 20 under the drive of motor A58, and then drive the already connected winding wheels 20 via motor B61 to selectively take up the line. Whether all winding wheels 20 are taken up in unison or some winding wheels 20 are selected for selective take-up, only motor A58 and motor B61 are used as the drivers. This ensures low cost while achieving unified or selective take-up of the two layers of winding wheels 20, resulting in high efficiency and strong practical effects.

[0060] The winding wheel 20 in the winding and releasing mechanism 11 of the present invention can be disassembled and assembled according to actual needs. When the winding wheel 20 does not need to wind and release the cable 63, the driving energy consumption of the motor A58 and the motor B61 can be reduced.
