Background

Chinese patent application No. 201310246151.0 discloses a hard infusion pipeline road crossing device, which comprises a hard infusion pipeline road crossing device, two support pipes; each supporting tube corresponds to the upper corner and the lower corner of one side of the inverted U-shaped hard infusion pipeline; a roller mechanism which is movably connected with the supporting tube is arranged at the corner of the top of the inverted U-shaped hard infusion pipeline; the rear part of the roller mechanism is arranged at the corner of the top part of the inverted U-shaped hard infusion pipeline, and the front part of the roller mechanism is sleeved on the supporting pipe and can slide along the supporting pipe; the upper part of the supporting tube is provided with a pulley mechanism, and the lower part of the supporting tube is provided with a hand winch; the front end of a steel wire rope on the hand winch penetrates through the pulley mechanism and is fixed on the roller mechanism; the bottom of the supporting tube is connected with the bottom corner of the inverted U-shaped hard infusion pipeline through a stay cable, and the self-locking of the winding drum of the hand winch is realized through the ratchet wheel. The device has the defect that when the pipeline needs to be put down from a high position, the ratchet wheel needs to be loosened to realize the reverse rotation of the winding drum, but after the ratchet wheel is loosened, the winding drum quickly drops under the force of the steel wire rope and the pipeline, and the pipeline can be damaged.

Disclosure of Invention

The invention aims to overcome the technical defects and provide a rope winding device, which solves the technical problem that a winding drum of a rope winding drum can rotate uncontrollably after a ratchet wheel is loosened by a hand winch in the prior art.

In order to achieve the above technical object, a technical solution of the present invention provides a rope winding device, including:

a housing assembly including a housing;

a spool assembly including a spool rotatably connected to the housing;

the transmission assembly comprises a first rotating shaft, an eccentric sleeve, a cycloid inner gear, a cycloid outer gear, a rotation stopping clamp, a first square locking block, a second square locking block, a fixed inner gear and a fixed outer gear, the first rotating shaft and the winding drum are coaxially arranged, and the eccentric sleeve is fixedly sleeved on the first rotating shaft along the axial direction of the first rotating shaft; the cycloidal inner gear is coaxially and rotatably sleeved on the first rotating shaft; the cycloid external gear is sleeved on the eccentric sleeve and is meshed with the cycloid internal gear; the rotation stopping clamp is connected to the shell and provided with a first guide groove along the radial direction of the first rotating shaft; the first square locking block is arranged in the first guide groove in a sliding mode along the guide direction of the first guide groove, a second guide groove is formed in the first square locking block along the radial direction of the first rotating shaft, the second guide groove is perpendicular to the first guide groove, the second square locking block is arranged in the second guide groove in a sliding mode along the guide direction of the second guide groove, and the second square locking block is connected to the cycloid outer gear; the fixed outer gear is coaxially connected with the cycloid inner gear, the fixed inner gear is sleeved on the fixed outer gear and meshed with the fixed outer gear, and the fixed inner gear is coaxially connected with the winding drum.

Compared with the prior art, the invention has the beneficial effects that: the first rotating shaft is rotated to drive the eccentric sleeve to rotate, at the moment, the first square locking block moves along the guide of the first guide groove, the second square locking block moves along the guide of the second guide groove, the movement directions of the first square locking block and the second square locking block are mutually vertical, the cycloid external gear performs circular motion along the axis of the cycloid internal gear and cannot rotate under the combined action of the eccentric sleeve, the rotation stopping clamp, the first square locking block, the second square locking block and the cycloid internal gear, the rotation of the cycloid external gear is irreversible, namely, the cycloid internal gear can only rotate under the condition of rotating the first rotating shaft, the cycloid internal gear cannot drive the first rotating shaft to rotate through the cycloid internal gear, the winding drum can only rotate when the first rotating shaft rotates, and the winding drum cannot drive the first rotating shaft to rotate, the steel wire rope can not drive the winding drum to rotate, and the problem that the steel wire rope and the pipeline are likely to be damaged due to the fact that the steel wire rope and the pipeline quickly fall down under the action of force can be effectively solved.
