[0046] The present embodiment provides a cable pay-off support, Figure 1 is a schematic diagram of the overall structure of the cable pay-off support of the present embodiment. Referring to Figure 1 , the cable pay-off support of the present embodiment includes a main shaft 10, a rotating shaft 20 and a base 50. Referring to Figure 3 and Figure 4The top end of the main shaft 10 is detachably provided with a mounting piece 11, and the mounting piece 11 is provided with a first rotating groove 111 opening upward. The rotating shaft 20 is rotatably sleeved outside the main shaft 10, and the outer side of the rotating shaft 20 is arranged in a circumferential direction and provided with a plurality of support arms 30 to stably support the cable. The base 50 is sleeved outside the main shaft 10 and located below the rotating shaft 20, which can keep the whole cable pay-off support stable and facilitate the operation of the cable. The top end of the rotating shaft 20 is detachably connected with a top cover 40. Referring to Figure 3 , the top cover 40 covers the main shaft 10 and the mounting piece 11, and the top cover 40 is provided with a second rotating groove 41 opening downward. Referring to Figure 3 , the cable pay-off support of the embodiment further comprises a rotating ball 60 rotatably arranged between the first rotating groove 111 and the second rotating groove 41. The rotating ball 60 can make the rotating shaft 20 rotate more smoothly relative to the main shaft 10, improve the convenience and stability of the cable pay-off support during use.

[0047] Specifically, referring to Figure 4 , the top end of the main shaft 10 is provided with a circular recess 15 inside, the recess 15 is communicated with the inside of the main shaft 10, and the mounting piece 11 is conveniently placed and fixed. The recess 15 is provided with two clamping grooves 16 on both sides in communication. Correspondingly, the mounting piece 11 is provided in a hemispherical structure, and the mounting piece 11 is provided with a clamping block 112 symmetrically on both sides. The clamping block 112 and the clamping groove 16 are matched with each other, and the mounting piece 11 is detachably connected to the top end of the main shaft 10 through the clamping block 112 and the clamping groove 16. Referring to Figure 3 and Figure 4 , the top cover 40 covers the mounting piece 11 correspondingly, so that a space for accommodating the limiting rotating ball 60 can be formed between the first rotating groove 111 and the second rotating groove 41. Referring to Figure 4 , the top cover 40 is provided in a hemispherical structure with a downward turned edge 42, the top surface of the rotating shaft 20 is provided with an upward turned edge 25, and the size of the downward turned edge 42 is the same as that of the upward turned edge 25. The downward turned edge 42 and the upward turned edge 25 are connected and fixed between the top cover 40 and the rotating shaft 20 through a plurality of bolts distributed at equal angles, thereby realizing detachable connection. The rotating shaft 20 rotates synchronously to drive the top cover 40 to rotate, and the arrangement of the rotating ball 60 can make the rotation of the top cover 40 more smooth and stable.

[0048] Optionally, the detachable connection between the top cover 40 and the rotating shaft 20 can also be achieved by a tight fit, such as providing a connecting ring with an inner diameter slightly larger than the outer diameter of the rotating shaft 20 on the lower surface of the top cover 40 to achieve connection with the rotating shaft 20; or the detachable connection between the top cover 40 and the rotating shaft 20 can also be achieved by a clamping block and a clamping groove. At the same time, the detachable connection between the mounting piece 11 and the main shaft 10 can also be achieved by a tight fit or a bolt connection; or the detachable connection between the mounting piece 11 and the main shaft 10 can also be achieved by a welding connection to improve the stability of the whole.

[0049] Wherein, referring to Figure 3 and Figure 4 , the first rotating groove 111 and the second rotating groove 41 are respectively provided as spherical grooves matched with the rotating sphere 60, so as to ensure that the position of the rotating sphere 60 will not change, thereby ensuring the stability of the rotating shaft 20 when rotating. In addition, the top surface of the mounting piece 11 is lower than the top surface of the rotating shaft 20, so as to avoid friction between the top cover 40 and the mounting piece 11 and increase the rotation resistance. The volume of the first rotating groove 111 is small, so as to reduce the contact area between the first rotating groove 111 and the rotating sphere 60, thereby reducing the friction damage to the rotating sphere 60.

[0050] Optionally, the first rotating groove 111 and the second rotating groove 41 can also be provided as spherical grooves with a size larger than that of the rotating sphere 60, so as to reduce the wear between the first rotating groove 111 and the rotating sphere 60; or provided as rectangular grooves matched with the rotating sphere 60, so as to limit the rotating sphere 60 while minimizing the contact area with the rotating sphere 60; or provided as any other shape capable of limiting the rotating sphere 60.

[0051] In addition, the detachable connection between the top cover 40 and the rotating shaft 20 and the detachable connection between the mounting piece 11 and the main shaft 10 can facilitate the replacement of worn parts. The independent arrangement between the mounting piece 11 and the main shaft 10 can also effectively reduce the cost and improve the convenience of replacing parts.

[0052] Referring to Figure 3 , the rotating shaft 20 and the main shaft 10 of the embodiment are connected by a rotating bearing 21. In addition, a rotating gap is provided between the rotating shaft 20 and the main shaft 10 to reduce unnecessary friction and ensure smooth rotation of the rotating shaft 20.

[0053] Referring to Figure 3, the main shaft 10 comprises a first part 13 and a second part 14 arranged in sequence from top to bottom, and the outer diameter of the first part 13 is larger than that of the second part 14. The top of the rotating shaft 20 is connected with the top cover 40 and rotates relative to the main shaft 10 through the rotating ball 60, and the bottom of the rotating shaft 20 is connected with the rotating bearing 21 to rotate relative to the main shaft 10, and the rotating ball 60 and the rotating bearing 21 jointly ensure the stability and safety of the rotation of the rotating shaft 20.

[0054] Specifically, referring to Figure 3 , the bottom of the rotating shaft 20 is provided with a mounting groove 22 in communication with the inside of the rotating shaft 20. The mounting groove 22 is arranged as an annular groove, the inner side wall is in communication with the inside of the rotating shaft 20, and the opening of the mounting groove 22 faces downward, facilitating the assembly of the rotating bearing 21. The size of the mounting groove 22 matches the size of the rotating bearing 21, which is used to limit and fix the rotating bearing 21. The size of the mounting groove 22 is larger than the outer diameter of the second part 14, so that the rotating bearing 21 can be sleeved outside the second part 14. The slot of the mounting groove 22 is connected with a limiting piece 23, which can limit the rotating bearing 21 in the mounting groove 22.

[0055] Referring to Figure 3 , the rotating bearing 21 of the embodiment comprises an inner ring 211, an outer ring 212 and a rolling body limited between the inner ring 211 and the outer ring 212. The inner diameter of the inner ring 211 is equal to the outer diameter of the second part 14 of the main shaft 10, and the outer diameter of the outer ring 212 is equal to the size of the mounting groove 22. When assembling the rotating bearing 21, first put the rotating bearing 21 into the mounting groove 22 from the bottom opening of the rotating shaft 20, and then limit and fix the rotating bearing 21 through the limiting piece 23. Then, the second part 14 of the main shaft 10 is inserted into the top end of the rotating shaft 20 until the bottom surface of the first part 13 (i.e. the top surface of the second part 14) abuts against the rotating bearing 21, thereby limiting and fixing the rotating bearing 21.

[0056] Referring to Figure 3 , when the rotating bearing 21 is fixed between the rotating shaft 20 and the main shaft 10, the upper surface of the mounting groove 22 is located in the same plane as the bottom surface of the first part 13. At this time, the inner ring 211 of the rotating bearing 21 abuts between the first part 13 and the limiting piece 23, and the outer ring 212 of the rotating bearing 21 abuts between the mounting groove 22 and the limiting piece 23. That is, a space capable of accommodating the fixed rotating bearing 21 is formed between the mounting groove 22, the limiting piece 23, the side surface and the top surface of the second part 14. This makes the rotating bearing 21, the rotating shaft 20 and the main shaft 10 form a tight support structure, and ensures that the rotating shaft 20 can rotate smoothly through the rotating bearing 21.

[0057] The limiting member 23 is detachably connected with the rotating shaft 20, so as to maintain or replace when necessary, ensuring the continuous and efficient operation of the whole system. In addition, in order to further optimize the rotation efficiency and stability of the rotating shaft 20, an appropriate amount of lubricant can be applied to the contact surfaces of the rotating ball 60 and / or the rotating bearing 21, the mounting groove 22 and the limiting member 23, so as to reduce friction and wear.

[0058] Further, referring to Figure 1 and Figure 2 , the one end of the support arm 30 is hinged with the rotating shaft 20 through the locking member 31, and the rotating state of the support arm 30 is adjusted to be in an unfolded state or a folded state through the locking member 31. The support arm 30 is connected to the rotating shaft 20 near the bottom, so that the cable drum can be completely sleeved on the rotating shaft 20, avoiding the cable from falling during construction operation.

[0059] Referring to Figure 1 and Figure 2 , the support arm 30 is provided with a support plate 32 and a reinforcing rib 33 connected with each other. The support plate 32 is provided as a rectangular plate, and the reinforcing rib 33 is provided as a right triangle. The longer side of the right angle of the reinforcing rib 33 is connected with the side of the support plate 32 away from the rotating shaft 20, so that the overall cross section of the support arm 30 presents a T-shaped structure, effectively enhancing the structural stability of the support arm 30. The shorter side of the right angle of the reinforcing rib 33 is connected with a first connecting member in the shape of a semicircle, and the first connecting member is provided with a through hole. The rotating shaft 20 is provided with a plurality of groups of second connecting members, two by two, and the second connecting members are also provided with through holes. When the support arm 30 is connected with the rotating shaft 20, the first connecting member is inserted between two second connecting members, and the locking member 31 passes through the three through holes in sequence to form a hinge between the support arm 30 and the rotating shaft 20.

[0060] Referring to Figure 1 and Figure 2 , the locking member 31 of the present embodiment includes a bolt and a nut. When the cable pay-off support is not needed, the locking member 31 is first adjusted to be loose, the support arm 30 is rotated to the folded state, and then the locking member 31 is tightened again, so as to store the cable pay-off support and prevent the support arm 30 from unfolding when stored. Similarly, when the cable pay-off support is needed, the locking member 31 is first loosened, the support arm 30 is rotated to the unfolded state, and then the locking member 31 is tightened again, improving the stability of the support.

[0061] Figure 1 In the figure, the support arm 30 is in the unfolded state. Figure 2 In the figure, the support arm 30 is in the folded state. Referring to Figure 2 , when the support arm 30 is in the folded state, the support arm 30 is rotated to be in contact with the rotating shaft 20, reducing the circumferential dimension of the cable pay-off support as a whole, so as to facilitate the carrying and moving of the cable pay-off support. Referring to Figure 1When the support arm 30 is in the unfolded state, the support arm 30 is rotated to be perpendicular to the rotating shaft 20, so as to conform to the shape of the cable drum, thereby ensuring the stability of the cable.

[0062] Further, referring to Figure 1 and Figure 2 , the bottom of the rotating shaft 20 is provided with a protrusion 24 in the circumferential direction, and the protrusion 24 is arranged below the support arm 30. The protrusion 24 is annular in structure, and the outer diameter of the protrusion 24 is greater than the outer diameter of the rotating shaft 20, so as to limit the support arm 30 when the support arm 30 is rotated to be perpendicular to the rotating shaft 20. In addition, the end of the inclined edge of the reinforcing rib 33 close to the rotating shaft 20 is provided with an abutting block 34. One side of the abutting block 34 is arranged in a circular arc shape which is matched in size with the protrusion 24. When the support arm 30 is rotated to be limited by the protrusion 24, the support arm 30 and the rotating shaft 20 form a predetermined angle and are in an unfolded state. At the same time, the abutting block 34 and the protrusion 24 conform to support, which can reduce the force received by the support arm 30 in the circumferential direction of the rotating shaft 20, avoid the support arm 30 from loosening and falling off, and ensure that the support arm 30 and the rotating shaft 20 form a stable support structure.

[0063] Alternatively, the protrusion 24 can not be arranged, and the size of the abutting block 34 can be extended so that the abutting block 34 can directly abut against the rotating shaft 20 when the support arm 30 is in the unfolded state.

[0064] Referring to Figure 1 and Figure 2 , in this embodiment, three support arms 30 are arranged on the outside of the rotating shaft 20. The three support arms 30 are distributed at equal angles along the circumference of the rotating shaft 20 to form a simple and stable support structure. Alternatively, the number of support arms 30 can also be set according to specific needs, such as four, five, six, eight, etc. In addition, in this embodiment, the protrusion 24 and the rotating shaft 20 are an integral structure. Referring to Figure 3 , the protrusion 24 and the mounting groove 22 are arranged at the same height position on the rotating shaft 20, and the mounting groove 22 is partially located in the protrusion 24, so as to optimize the structural layout of the rotating shaft 20. This can not only meet the design of the protrusion 24, but also avoid the rotating shaft 20 from forming a thicker cavity wall due to the arrangement of the mounting groove 22, thereby generating greater rotating resistance.

[0065] Further, referring to Figure 1 and Figure 2 , the base 50 of this embodiment is adjustably sleeved on the outside of the main shaft 10 in the height direction, so as to improve the flexibility of the cable pay-off support, and make the cable pay-off support more easily adapt to different working environments and needs.

[0066] Specifically, referring to Figure 1 and Figure 2The base 50 comprises a connecting rod 51 and a chassis 53 connected with each other. The connecting rod 51 is sleeved on the outer side of the second part 14 of the main shaft 10, and the chassis 53 is arranged at the bottom end of the connecting rod 51 to support the overall structure. The cable pay-off support of the embodiment adjusts the length of the overall support by adjusting the length of the main shaft 10 extending out of the connecting rod 51, and then limits and fixes the main shaft 10 relative to the base 50 to facilitate subsequent placement of the cable.

[0067] With reference to Figure 1 and Figure 2 The connecting rod 51 is provided with a plurality of first adjusting holes 511 transversely penetrating, and the plurality of first adjusting holes 511 are arranged in sequence along the height direction. With reference to Figure 3 The main shaft 10 is provided with a first fixing hole 12 corresponding to the transverse penetration. The base 50 further comprises a first positioning member 52. The first positioning member 52 can extend into different first adjusting holes 511 and be connected with the first fixing hole 12, so as to limit and fix the relative position between the connecting rod 51 and the main shaft 10, and realize the adjustment of the overall height of the cable pay-off support. The adjustment structure is simple and stable, and can guarantee the overall stability.

[0068] Optionally, the first positioning member 52 can be in the form of a bolt or a pin, and is connected with the first adjusting hole 511 and the first fixing hole 12 by means of threaded connection or direct insertion.

[0069] It can be understood that the main shaft 10 and the connecting rod 51 can also be provided with a plurality of adjusting holes penetrating on the main shaft 10, a fixing hole penetrating on the connecting rod 51, or a plurality of holes penetrating on both the main shaft 10 and the connecting rod 51 to facilitate adjustment, which is not limited here.

[0070] Optionally, the main shaft 10 and the connecting rod 51 can be connected by simple plug-in connection, and the length of the main shaft 10 extending out of the connecting rod 51 can be adjusted by simple plug-in action, and the main shaft 10 is limited and fixed by the first positioning member 52. This way is simple, convenient and easy to operate; or the main shaft 10 and the connecting rod 51 can also be connected by thread connection by providing external threads on the main shaft 10 and internal threads on the inner wall of the connecting rod 51, and the length of the main shaft 10 extending out of the connecting rod 51 can be adjusted by simply rotating the main shaft 10, and then the main shaft 10 is limited and fixed by the first positioning member 52. The threaded connection can accurately control the length of the main shaft 10 extending out, and is helpful for quickly aligning the first adjusting hole 511 and the first fixing hole 12, and facilitating the installation and positioning of the first positioning member 52; and other devices such as driving structures can also be connected in the cable pay-off support according to specific conditions to drive the main shaft 10 to move and fix, so as to increase the convenience of adjustment, such as a jack, a pneumatic lifting column and the like.

[0071] Further, with reference to Figure 1 and Figure 2The base 50 is further provided with a plurality of telescopic legs 55 of adjustable length. When adjusting the height of the cable pay-off support, the length of the telescopic legs 55 can be adjusted according to the actual situation to ensure the stability of the cable pay-off support as a whole.

[0072] Specifically, referring to Figure 1 and Figure 2 , the chassis 53 in the embodiment is provided with a plurality of telescopic grooves 54, and the grooves of the telescopic grooves 54 face outward. One end of each telescopic leg 55 is respectively inserted into the telescopic groove 54 one by one, and the other end is located outside the telescopic groove 54 to realize length extension. Referring to Figure 3 , the top end of each telescopic groove 54 is provided with a second fixing hole 541. The base 50 further includes a plurality of second positioning members 56. The top surface of the telescopic leg 55 is provided with a plurality of second adjusting holes 551 along the extension direction of the telescopic groove 54. Each second positioning member 56 respectively passes through the second fixing hole 541 and extends into the different second adjusting holes 551 to fix the plurality of telescopic legs 55 and the chassis 53, thereby realizing the effect of adjusting the length.

[0073] It can be understood that a plurality of adjusting holes can also be provided on the top surface of the telescopic groove 54, and a fixing hole is provided on the top surface of the telescopic leg 55; or a plurality of holes are provided on the telescopic groove 54 and the telescopic leg 55 to facilitate adjustment.
