[0023] like Figure 1-Figure 3 As shown,
[0024] As an optional embodiment,
[0025] A pay-off reel with a height adjustment structure comprises a first base plate 1, on which a pay-off frame 2 is arranged, and first U-shaped support frames 3 for support are installed at both ends of the pay-off frame 2, and adjustment components 4 are arranged on the sides of the two first U-shaped support frames 3, and the two adjustment components 4 comprise a first bracket 41, an internally threaded sleeve 42, a threaded rod 43, a first bearing seat 44 and an arc-shaped support plate 45, one end of the first bracket 41 is hinged to the side of the arc-shaped support plate 45, and the other end of the first bracket 41 is hinged to the top of the internally threaded sleeve 42, the threaded rod 43 is inserted into the internally threaded sleeve 42 threadedly matched therewith, and both ends of the threaded rod 43 are connected to the first base plate 1 through the first bearing seat 44.
[0026] Specifically, the pay-off frame 2 is used to provide a space for collecting and releasing cables. Both ends of the pay-off frame 2 are placed in the U-shaped grooves of the two first U-shaped support frames 3. The pay-off frame 2 can move up and down in the U-shaped groove. In order to quickly position after the up and down movement, an adjustment component 4 is designed. The appropriate height can be selected through the adjustment component 4. The specific working method is as follows:
[0027] When the height of the wire-paying frame 2 needs to be adjusted, it is only necessary to rotate the threaded rod 43 to make the threaded rod 43 rotate on the first bearing seat 44. When the threaded rod 43 rotates, the internal threaded sleeve 42 sleeved on the threaded rod 43 is displaced along its central axis, so that the arc support plate 45 connected by the first bracket 41 can move vertically on the side of the first U-shaped support frame 3, thereby driving the wire-paying frame 2 on the arc support plate 45 to rise and fall. When the wire-paying frame 2 is small, the threaded rod 43 can be rotated, and the angle between the center line of the first bracket 41 and the center line of the threaded rod 43 gradually decreases, so the height of the wire-paying frame 2 can be lowered. Conversely, when the wire-paying frame 2 is large, the threaded rod 43 can be rotated in the opposite direction, and the angle between the center line of the first bracket 41 and the center line of the threaded rod 43 gradually increases until a vertical angle is formed, so that the height of the wire-paying frame 2 is at the highest position. By adjusting the height position change of the wire-paying frame 2 on the first U-shaped support frame 3, it can be suitable for the placement of wire-paying reels of different diameters.
[0028] Based on the first embodiment, Figure 2 As shown:
[0029] Specifically, two first brackets 41 are provided, and the two first brackets 41 are symmetrically distributed in the shape of an "eight" on the side of the arc-shaped support plate 45. One end of each of the first brackets 41 is hinged to the side of the arc-shaped support plate 45, and the other end of each of the first brackets 41 is hinged to an internally threaded sleeve 42. The two first brackets 41 symmetrically distributed in the shape of an "eight" provide a more stable support for the arc-shaped support plate 45. The internally threaded sleeves 42 are sleeved on the surface of the threaded rod 43, one positive and one negative. When the threaded rod 43 is subsequently rotated, the left and right internally threaded sleeves 42 approach or move away synchronously, thereby realizing the final height change of the pay-off frame 2.
[0030] Based on the first embodiment, Figure 2 As shown:
[0031] A universal ball 47 is installed at the bottom of each internally threaded sleeve 42. The bottom of the universal ball 47 is supported on the first base plate 1. The universal ball 47 allows the internally threaded sleeve 42 to slide on the universal ball 47, providing support while reducing the friction resistance between the two.
[0032] A first guide rail 46 is vertically installed on the side of the first U-shaped support frame 3, and a slide groove cooperating with the first guide rail 46 is opened on the side of the arc-shaped support plate 45. Through the cooperation between the first guide rail 46 and the slide groove, a guiding effect is provided for the vertical movement of the arc-shaped support plate 45 on the side of the first U-shaped support frame 3 to avoid the arc-shaped support plate 45 from deflecting.
[0033] As shown in FIG3 , a driving assembly 5 for synchronously driving the two threaded rods 43 to rotate synchronously is installed on the first bottom plate 1 , and the driving assembly 5 can be used to control the two threaded rods 43 to rotate synchronously at the same time later.
[0034] like Figure 2 As shown, the two driving components 5 include a box body 51, and one end of the two threaded rods 43 inserted into the box body 51 is equipped with a synchronous wheel 55, and a first synchronous belt 53 is connected between the two synchronous wheels 55. Subsequently, only one of the synchronous wheels 55 needs to be rotated to drive the two threaded rods 43 to rotate synchronously at the same time, thereby realizing the linkage of the two threaded rods 43 to meet the synchronous lifting and lowering of the two ends of the wire pay-off frame 2, so that the overall force is more stable.
[0035] In order to facilitate the rotation of the synchronous wheel 55, a knob 6 for driving the synchronous wheel 55 to rotate is selected to be installed on the box body 51; a cover plate 52 is arranged on the top of the box body 51, and a slot matching with the cover plate 52 is opened on the box body 51. After the parts inside the box body 51 are assembled, the cover plate 52 is connected to the box body 51 by snap connection, so as to isolate the internal parts and achieve the purpose of protection.
[0036] A first motor 7 is installed on the first base plate 1, and the first motor 7 is used to drive the pay-off frame 2 to rotate on the first U-shaped support frame 3. The forward and reverse rotation of the first motor 7 can be controlled subsequently to realize the rotation of the pay-off frame 2 on the first U-shaped support frame 3, so as to achieve the purpose of fast winding or unwinding.
[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
