Description

Technical Field

[0001] The utility model relates to the technical field of winches, in particular to a disc-type micro winch. Background Art

[0002] Data collection from the drill bit during oil drilling often requires adapting to the harsh drilling environment and accommodating existing drilling equipment. Therefore, to withstand these extreme drilling conditions, the winch needs to be compact and have high lifting torque to ensure stable operation under high pressure and load conditions. Existing winches primarily utilize a fixed frame, with a cable routing mechanism that pushes the cable. This forces the cable, in turn, subjecting it to lateral forces. For optical cables, these forces can potentially break the internal fibers. Utility Model Content

[0006] The winch assembly comprises a winch active side, a cylindrical winch body and a winch passive side in sequence, wherein the winch body is connected to the winch active side and the winch passive side via a connecting member;

[0007] A winch bracket, the winch bracket comprising an upper winch bracket and a lower winch bracket, the upper winch bracket comprising a winch base, and the motor assembly being mounted on the front of the winch base;

[0008] The winch assembly is connected to the vertical frame through the winch bracket.

[0009] Furthermore, the upper winch bracket and the lower winch bracket are connected by bolts; the sides of the upper winch bracket and the lower winch bracket are fastened by end covers, and the end covers are fixedly connected to the winch assembly by bolts.

[0010] Furthermore, the winch lower bracket also includes at least two vertically arranged support plates, and the support plates are connected to the vertical slide rails of the vertical frame.

[0011] Furthermore, the winch body includes a winch upper body and a winch lower body, and the winch upper body and the winch lower body are spliced ​​to form a circular winch body.

[0012] Furthermore, a large gear is provided on the active side of the winch, and the torque is transmitted to the middle through symmetrically arranged keys, and a bearing end cover is provided on the passive side of the winch.

[0013] The positive effects of this utility model are:

[0014] 1. The winch assembly is installed through a winch bracket that can slide up and down along the vertical rack track. It has the characteristic of the cable outlet point being fixed, and the cable force is more stable, ensuring the reliability of data transmission.

[0015] 2. The winch assembly adopts an integral reel-type design, with a small number of guide wheels, fewer bending times of the torsion cable, and high cable guide structure strength; the winch adopts a cylindrical winch body formed by splicing the winch upper body and the winch lower body, with a large center reserved space, which is suitable for various structures such as photoelectric slip rings and pre-stored cables.

[0038] like Figure 1-6 As shown, this embodiment provides a reel-type micro winch with modular components. The winch utilizes a gear transmission structure, a vertical layout, rear cable outlet, and two rows of reserved mounting holes, adapting to various equipment specifications and ensuring good compatibility. The cable arrangement adopts an integrated reel-type design, which reduces the number of guide pulleys, reduces the number of bends in the torsion-resistant cable, and improves the strength of the cable guide structure. The large center space reserved for the winch can accommodate various structures such as optical slip rings and pre-stored cables.

[0039] like Figures 3 to 5 As shown, the disc-walking mini winch includes a vertical frame 1, a motor assembly 2, a reduction gearbox 3, and a winch assembly 4. The winch assembly 4 includes a winch active side 41, a cylindrical winch body 43, and a winch passive side 42. The cylindrical winch body 43 is connected to the winch active side 41 and the winch passive side 42 by connecting bolts.
