Description

Technical Field

[0001] The utility model relates to a cable winch with an internal drive, and relates to the technical field of winch equipment. Background Art

[0002] After the cable is produced, it needs to be wound and stored for transportation and subsequent use. The cable is usually wound using a winch device, and the scattered cable can be quickly and neatly wound by an electric winch.

[0003] Most of the existing cable winches are the cooperation of a winding drum and a driving mechanism. The driving mechanism is arranged outside the winding drum to drive the winding drum to realize cable winding. The patented technology with the publication number CN111517169B discloses a remaining cable winding device, which relates to the field of cable processing and storage, including a base, a motor, a driving turntable, an adjustable shaft, an adjusting rod and a driven turntable. The motor is installed on the base, and the output shaft of the motor is connected to the driving turntable through a chassis. A central shaft and an adjustable shaft are fixedly connected to the center of the driving turntable. By setting the motor and the driving turntable, the remaining cable can be quickly and conveniently wound. At the same time, by setting the adjustable shaft, different winding radii can be selected according to the length and diameter of the remaining cable, with a wide range of applications. At the same time, the rotating seat can be slid to make the distance between the driven turntable and the driving turntable adjustable, which is convenient to control the width of the wound cable. And this device adopts the horizontal axis winding method. Compared with the vertical axis winding, the wound cable is arranged more evenly, and the nylon rope for bundling can be placed in position in advance before winding. In this way, the cable can be easily and quickly bundled after winding to avoid scattering. In this scheme, different cables can be wound well, but the motor is arranged outside the turntable, which not only increases the overall volume of the equipment, but also needs to consider the waterproof and dustproof problems of the motor, increasing the maintenance difficulty, and it lacks a guiding mechanism during cable winding, and it is easy to have the situation of cable overlap and bulging during winding.

[0023] Refer to Figures 1-5As shown in the figure, the technical solution adopted in this specific embodiment is as follows: It includes a fixed frame 1, a winding mechanism 2, and a wire guiding mechanism 3. The winding mechanism 2 and the wire guiding mechanism 3 are arranged inside the fixed frame 1, and the wire guiding mechanism 3 is arranged above the winding mechanism 2. The winding mechanism 2 includes a winding drum 2-1, a driving turntable 2-2, a driven turntable 2-3, a driving motor 2-4, and a main shaft 2-5. The driving turntable 2-2 and the driven turntable 2-3 are movably arranged at both ends of the main shaft 2-5. The winding drum 2-1 is connected to the driving turntable 2-2 and the driven turntable 2-3. The driving motor 2-4 is arranged on the main shaft 2-5. A conductive slip ring 2-8 is arranged inside the driving turntable 2-2 and is electrically connected to the driving motor 2-4. In most existing cable winding devices, the driving mechanism is arranged outside the winding drum, which requires additional waterproof and dustproof settings and will increase the occupied area during use. In this embodiment, the driving motor is arranged inside the winding drum and is powered through a conductive slip ring to drive the driving turntable to rotate. The driving turntable drives the winding drum and the driven turntable to rotate to realize cable winding. It should be noted that a through hole for fixing the cable is arranged on the winding drum. The cable first passes through the wire guiding mechanism and then through the through hole. When the winding drum rotates, the winding operation starts;

[0024] During the cable winding process, to avoid uneven arrangement of the cable, the cable is guided and wound through the wire guiding mechanism. Specifically, the wire guiding mechanism 3 includes a reciprocating shaft 3-1, a guiding block 3-2, and a guiding shaft 3-3. The reciprocating shaft 3-1 and the guiding shaft 3-3 are both movably connected to the guiding block 3-2 and are installed on the fixed frame 1. Crossed guiding grooves are arranged on the reciprocating shaft 3-1. An active guiding rotating block is arranged inside the guiding block and is matched with the guiding grooves. During the rotation of the reciprocating shaft, the guiding rotating block drives the guiding block to move along one guiding groove, guiding the cable in one direction. When reaching the vertex, the guiding rotating block is guided by another guiding groove to rotate and enters another guiding groove, driving the turning block to move in the opposite direction, realizing the reverse winding arrangement of the cable, thus effectively solving the problem of bulging of the cable during the winding process.

[0025] More specifically, a driving gear 2-7 is arranged at the output end of the driving motor 2-4. A driven gear 2-6 is arranged inside the conductive slip ring 2-8. The driven gear 2-6 meshes with the driving gear 2-7. The driving of the driving turntable by the driving motor is realized through the cooperation of the driving gear and the driven gear.

[0026] More specifically, a connecting rod 2-9 is arranged between the driving turntable 2-2 and the driven turntable 2-3. By setting the connecting rod, the connection stability between the two turntables is increased.

[0027] More specifically, a guiding driving gear 2-10 is arranged on the main shaft 2-5 outside the driving turntable 2-2. The driving gear is mainly used for driving connection with the wire guiding mechanism to drive the wire guiding mechanism.

[0028] More specifically, a wire threading hole 3-2-1 is provided on the guiding block 3-2. The wire threading hole is used to pass through a cable to achieve the winding and guiding of the cable.

[0029] More specifically, bearings are provided at both ends of the reciprocating shaft 3-1 and are connected to the fixed frame 1. A driven guiding gear 3-4 is provided at one end close to the guiding driving gear 2-10. The driven guiding gear 3-4 is connected to the guiding driving gear 2-10 through a chain. The wire guiding mechanism rotates and guides through the transmission connection between the driven guiding gear and the guiding driving gear. In this embodiment, it is schematically shown as the transmission connection between a gear and a chain.

[0030] More specifically, a controller is provided outside the fixed frame 1. The controller is electrically connected to the conductive slip ring 2-8. The controller integrates a start switch, a control main board, and a leakage protection switch.

[0031] The working principle of the present utility model: The driving motor 2-4 is arranged inside the winding drum 2-1 and fixed on the main shaft 2-5. Both ends of the main shaft 2-5 are fixed on the fixed frame 1, and the main shaft 2-5 is connected to the two turntables through bearings. The main shaft 2-5 does not rotate during winding. The driving motor 2-4 performs power supply operations through the conductive slip ring 2-8. The driving gear 2-7 drives the driven gear 2-6 to drive the entire winding mechanism 2 to rotate for winding operations. A fixing hole for the cable is also provided on the winding drum 2-1. The cable is first passed through the wire threading hole 3-2-1, then passed through the fixing hole, and then the winding operation is started. During winding, the winding drum 2-1 drives the cable to rotate and wind. The reciprocating shaft 3-1 rotates, and under the cooperation of the guiding rotating block and the guiding groove, the guiding block 3-2 moves on the reciprocating shaft 3-1, so that the cable is evenly wound on the winding drum. Since the driving motor 2-4 is an internal structure and is powered by the conductive slip ring 2-8, the wiring is simpler, and after the driving motor 2-4 is built-in, it will not be affected by external rainwater, and the waterproof and dustproof effects are better.

[0032] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model should be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
