Description

Technical Field

[0001] The utility model belongs to the technical field of performance equipment, and in particular relates to a rotating dumping device for large props. Background Art

[0002] Due to the need of viewing performances, during outdoor performances, when switching between different scenes, the large fixed props in the previous performance (located between the audience and the next performance) must be lowered so that the audience can enjoy the next performance. Due to the objective conditions on site, it is not possible to excavate a deep foundation pit for the lifting of props. Therefore, a rotating dumping device for large props during performances is needed.

[0003] Since large props have large dimensions and their center of gravity is far from the rotating hinge, the driving torque increases accordingly. The existing driving method is hydraulic cylinder driving. However, the hydraulic cylinder driving method requires a hydraulic pump station to provide a power source, and the presence of hydraulic oil involves fire inspection. Once the system leaks hydraulic oil, it will pollute the environment. Utility Model Content

[0004] The utility model aims to provide a rotating dumping device for large props to solve the above technical problems.

[0005] The utility model provides a rotating and tipping device for large props, comprising a spare driving motor, a right-angle commutator, a direct-connected motor, a planetary reducer, a stage device, and a rotating shaft;

[0006] The choreography device is connected to the rotating shaft, the rotating shaft is connected to the planetary reducer, the planetary reducer is connected to the direct-connected motor, and the direct-connected motor is connected to the standby drive motor via the right-angle commutator;

[0007] The directly connected motor is used to provide a power source for the planetary reducer under normal working conditions; the planetary reducer is used to provide torque output to the rotating shaft; the rotating shaft is used to drive the stage design to perform a rotating and tilting action; the backup drive motor is used to provide a power source for the planetary reducer when the directly connected motor fails.

[0008] Furthermore, the device also includes a limit switch for preventing the stage design device from colliding at an extreme position.

[0009] Furthermore, the device also includes a mechanical limit switch for ensuring that the stage design is not damaged when the limit switch fails.

[0010] By means of the above scheme, through the rotating and tipping device of the large props, the driving mode of the electric motor matched with the planetary reducer is adopted to realize the rotating and tipping of the large props, thereby meeting the rotating and tipping requirements of the large props during the performance.

[0019] The specific implementation of the utility model is further described in detail below in conjunction with the drawings and embodiments.

[0020] The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0021] Ginseng Figures 1 to 5As shown, this embodiment provides a rotating and tipping device for a large prop, including a spare drive motor 1, a right-angle commutator 2, a direct-connected motor 3, a planetary reducer 4, a stage device 5, and a rotating shaft 6; the stage device 5 is connected to the rotating shaft 6, the rotating shaft 6 is connected to the planetary reducer 4, the planetary reducer 4 is connected to the direct-connected motor 3, and the direct-connected motor 3 is connected to the spare drive motor 1 through the right-angle commutator 2; the direct-connected motor 3 is used to provide a power source for the planetary reducer under normal working conditions; the planetary reducer 4 is used to provide torque output to the rotating shaft 6; the rotating shaft 6 is used to drive the stage device 5 to perform a rotating and tipping action; the spare drive motor 1 is used to provide a power source for the planetary reducer 4 when the direct-connected motor 3 fails.

[0022] This embodiment uses a P series planetary reducer 4 to achieve torque output. The P series planetary reducer is matched with a 2.2kw direct-connected motor 3 to realize the power source under normal working conditions. In order to avoid affecting the audience's viewing experience due to performance equipment failure, a backup drive motor 1 is designed at the tail of the direct-connected motor 3. In order to save space, this device arranges the backup motor and the direct-connected motor (main drive motor) in a 90° direction through a set of right-angle commutators 2, making maximum use of space. Under normal working conditions, the direct-connected motor 3 outputs power to the backup drive motor 1 to rotate with the main motor (no power output). Once the main motor fails, the power source is switched to the backup drive motor 1, thereby ensuring the smooth progress of the performance.

[0023] In this embodiment, the device also includes a limit switch 7 for preventing the choreography device 5 from bumping at the limit position. In order to protect the choreography device from bumping at the limit position during the rotation of the entire device, limit switches 7 are designed at the lowest and highest positions. When the limit switch is triggered when the device rotates to the designed position, the device stops running.

[0024] In addition to the electrical limit switch, the device also includes a mechanical limit switch 8 for ensuring that the stage design 5 is not damaged to the greatest extent possible when the limit switch 7 fails.

[0025] The rotating and tipping device of the large prop adopts the driving mode of matching the motor with the planetary reducer to realize the rotating and tipping of the large prop, which can meet the rotating and tipping requirements of the large prop during the performance. The planetary reducer has the characteristics of large speed ratio and large torque, which is consistent with the requirement that the large prop rotates slowly and needs a large driving torque. The planetary reducer occupies less space than the hydraulic cylinder, and can also solve the problem of insufficient installation space for the drive.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
