[0028] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0030] Reference Figures 1 to 3 As shown, a cable-feeding arm rotation device includes a housing 1, a hollow turntable 2, a drive shaft 3, a power source 4, and a handle 5;

[0031] The hollow turntable 2 is rotatably mounted in the housing 1, and the outer peripheral wall of the hollow turntable 2 is provided with rollers; the hollow turntable 2 is connected to the support of the cable feeding arm, thereby driving the support of the cable feeding arm to rotate.

[0032] The drive shaft 3 passes through the housing 1. The drive shaft 3 is equipped with a cam, which is engaged with the roller drive. The drive shaft 3 is divided into a first end and a second end along its axial direction. The first end is used to connect to the power source 4, and the second end is used to connect to the handle 5.

[0033] One of the power source 4 and the handle 5 is connected to the drive shaft 3;

[0034] The cam on the drive shaft 3 engages with the rotor of the hollow turntable 2. When the drive shaft 3 rotates, the cam moves the rotor, causing the hollow turntable 2 to rotate. The first end of the drive shaft 3 can be connected to the power source 4, which drives the drive shaft 3 to rotate. If the power source 4 fails, it can be removed, and the handle 5 can be connected to the second end of the drive shaft 3. The handle 5 can be manually cranked to rotate the drive shaft 3. Through this structural design, when the power source 4 fails, the drive can be switched to the handle 5 in time, allowing the cable feeding arm to operate continuously.

[0035] The cam and roller drive structure in this embodiment is prior art, and can be found in patents 202422319086.6 and 202021439877.8. It will not be described in detail here.

[0036] In this embodiment, a connecting hole is provided on the end face of the first end, a first flange seat 11 is fixed on the housing 1, the power source 4 is installed on the first flange seat 11 by locking screws, the output shaft of the power source 4 passes through the connecting hole, a key is installed on the output shaft of the power source 4, the connecting hole has a keyway, and the transmission shaft 3 is connected to the output shaft of the power source 4 by key transmission. Therefore, the power source 4 can drive the transmission shaft 3 to rotate.

[0037] The first flange seat 11 is provided with a threaded hole, which passes through the first flange seat 11 along the axial direction of the drive shaft 3. A push-out screw 6 is threadedly connected in the threaded hole. The push-out screw 6 passes through the threaded hole from the side of the first flange seat 11 away from the power source 4. The length of the push-out screw 6 is greater than the depth of the threaded hole.

[0038] When the power source 4 fails, it needs to be disassembled. However, the connection between the drive shaft 3 and the output shaft of the power source 4 is relatively tight, making it sometimes difficult to pull out the power source 4. Therefore, an ejector screw 6 is provided. By rotating the ejector screw 6, the ejector screw 6 can pass through the threaded hole and contact the power source 4, thereby pushing the power source 4 to separate from the first flange seat 11, which assists in the disassembly of the power source 4. When it is not necessary to disassemble the power source 4, the ejector screw 6 will not pass through the threaded hole, so it will not affect the use of the power source 4.

[0039] In this embodiment, the axial direction of the hollow turntable 2 is vertical, which facilitates the arrangement and connection of the cable feeding arm bracket. There are two threaded holes, which are respectively located on the upper and lower parts of the first flange seat 11. This allows for the installation of two ejector screws 6 to symmetrically eject the power source 4, preventing the output shaft of the power source 4 from getting stuck in the connection hole.

[0040] In this embodiment, the power source 4 is a hydraulic motor.

[0041] In some other embodiments, the power source 4 may also be an electric motor.

[0042] In this embodiment, the outer periphery of the second end is a spline tooth structure, and the handle 5 has a spline sleeve 51, which is used to fit onto the spline tooth structure.

[0043] When using handle 5, spline sleeve 51 is fitted onto spline tooth structure, and the inner wall of spline sleeve 51 meshes with spline tooth structure. By rotating spline sleeve 51 through handle 5, the drive shaft 3 is rotated.

[0044] In this embodiment, the handle 5 includes a swing arm 52 and a handle 53;

[0045] Spline sleeve 51 is fixed to one end of rocker arm 52 along its length direction, and the length direction of rocker arm 52 is perpendicular to the axis of spline sleeve 51.

[0046] The handle 53 is fixed to the other end of the swing arm 52 away from the spline sleeve 51, and the length direction of the handle 53 is perpendicular to the length direction of the swing arm 52.

[0047] When in use, grasp the handle 53 to shake the swing arm 52, thereby rotating the spline sleeve 51.

[0048] In this embodiment, a second flange seat 12 is fixed on the housing 1, and the drive shaft 3 passes through the second flange seat 12 to expose the second end.

[0049] It also includes a cover 7. When the drive shaft 3 is connected to the power source 4, it means that the handle 5 is not connected to the drive shaft 3. At this time, the cover 7 is detachably connected to the second flange seat 12 and covers the second end, which can protect the spline tooth structure. When it is necessary to connect the handle 5 to the drive shaft 3, the cover 7 is removed. The cover 7 can be installed on the second flange seat 12 by screws, clips or Velcro.

[0050] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
