Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 4 The present invention discloses a rotating working bucket for an insulated bucket truck, comprising a rotating working bucket body 1, which is mounted on the top of the insulated bucket truck 2. The rotating working bucket body 1 consists of a support base 3, a rotating bucket 4, and a rotating drive assembly 5. The bottom end of the rotating bucket 4 is inserted into the interior of the support base 3 and is rotatably connected to the support base 3 through a plane bearing 6. The rotating drive assembly 5 is connected between the support base 3 and the rotating bucket 4. An annular limiting platform 7 is fixedly provided on the bottom end of the side of the rotating bucket 4, and several limiting components 8 matching the annular limiting platform 7 are provided through the top end of the side of the support base 3.

[0023] In use, the rotating bucket 4 is driven to rotate by the rotating drive component 5, so as to adjust the direction of the staff. The staff does not need to adjust their position inside the rotating bucket 4, thus ensuring the safety of the staff and improving the convenience of the staff's work.

[0024] The rotary drive assembly 5 consists of a servo motor 9, a reducer 10, a drive gear 11, and an internal gear ring 12. The reducer 10 is embedded in the side of the bottom end of the support base 3. The servo motor 9 is fixedly connected to the bottom end of the reducer 10. The output shaft of the servo motor 9 is connected to the input shaft of the reducer 10. The drive gear 11 is fixedly connected to the output shaft of the reducer 10. A groove 13 is provided in the middle of the bottom end of the rotating bucket 4. The internal gear ring 12 is fixedly connected to the inner side wall of the groove 13 and meshes with the drive gear 11.

[0025] Servo motor 9 and reducer 10 drive drive gear 11 to rotate, drive gear 11 drives internal gear ring 12 to rotate, internal gear ring 12 drives rotating bucket 4 to rotate, thus realizing rotation adjustment;

[0026] The limiting assembly 8 consists of a hydraulic rod 14, a slide 15, a universal ball bearing 16, and a universal ball bearing 2 17. The top of the inner side wall of the support base 3 is provided with several sliding grooves 18. The slide 15 is slidably connected to the inside of the sliding grooves 18. The hydraulic rod 14 is fixedly connected to the top of the side of the support base 3 and is fixedly connected to the slide 15. The universal ball bearing 16 is connected to the end of the slide 15 away from the hydraulic rod 14 and is in contact with the side of the rotating bucket 4. The universal ball bearing 2 17 is connected to the bottom of the slide 15 and is in contact with the top surface of the annular limiting platform 7.

[0027] Universal ball bearing 16 and universal ball bearing 2 17 respectively limit the radial and axial movement of the rotating bucket 4, improving the stability of the rotating bucket 4. Hydraulic rod 14 can drive the slide 15 to move, thereby releasing the limit on the rotating bucket 4, which facilitates the disassembly and installation of the rotating bucket 4, and thus facilitates later inspection and maintenance.

[0028] An umbrella-shaped protective cover 19 is fixedly installed on the outer surface of the rotating bucket 4, which can play a protective role.

[0029] A hydraulic rod 20 is installed through the center of the bottom end of the support base 3. A friction disc 21 is fixedly connected to the hydraulic rod 20 inside the support base 3. A friction disc 22 matching the friction disc 21 is fixedly installed at the top of the groove 13. Several limiting rods 23 are fixedly installed on the side of the bottom end of the friction disc 21. Several limiting holes 24 that are slidably connected to the limiting rods 23 are opened on the support base 3.

[0030] When the rotating bucket 4 is not rotating, the hydraulic rod 20 drives the friction disc 21 to rise, so that the friction disc 21 and the friction disc 22 are in contact, achieving friction limit and preventing the rotating bucket 4 from rotating on its own due to wind force, thus improving the stability and safety of the rotating bucket 4. The limit rod 23 and the limit hole 24 realize vertical limit of the friction disc 21, preventing the hydraulic rod 20 from being subjected to torque and affecting its service life.

[0031] During operation, the system features a support base, a rotating bucket, and a rotary drive assembly consisting of a servo motor, reducer, drive gear, and internal gear ring. Rotation adjustment is achieved without altering the operator's approximate position, only changing their direction. This eliminates the need for repeated movement within the bucket, improving safety and ease of operation. A limiting assembly comprised of hydraulic rod one, a slide, universal ball bearing one, and universal ball bearing two, along with a ring-shaped limiting platform, provides axial and radial limiting for the rotating bucket, enhancing its stability and facilitating installation and disassembly, thus improving maintenance convenience. Finally, hydraulic rod two, friction disc one, friction disc two, a limiting rod, and a limiting hole further restrict the bucket's rotation, preventing it from rotating due to wind at high altitudes and compromising safety.
