Description

Technical Field

[0001] The present application belongs to the technical field of power equipment, and in particular, relates to a multi-fast switching power equipment. Background Art

[0002] Power equipment is a device that converts, conducts and adjusts various potential energy sources in nature. That is, in the production process of an enterprise, it can convert nature's potential energy into mechanical energy, then convert mechanical energy into electrical energy, and convert electrical energy into mechanical energy. For example, a long-stroke lead screw needs to rotate more times when working, so an electric motor is usually used as a power device to drive it.

[0003] The utility model with the existing authorization announcement number CN210623489U discloses a power input quick switching device, including a reduction mechanism, an overrunning clutch mechanism and an electromagnetic clutch mechanism. The overrunning clutch mechanism includes an outer ring, a fixed frame and an inner ring that rotate coaxially from the outside to the inside. The inner ring is a regular N-gon structure, and N groups of rollers are rotatably installed in a circular array inside the fixed frame.

[0004] The above-mentioned technical scheme is adopted to integrate two sets of independent power inputs at the same time, and different reduction devices are used to adapt to different input methods to realize rapid switching of power input. However, in the above-mentioned technical scheme, the motor power device itself cannot quickly disconnect the transmission relationship with the lead screw. Then, when the motor power device needs to use manual rotation of the lead screw due to power failure, it is necessary to drive the motor power device to rotate together, which greatly increases the load when the lead screw is manually rotated, making it impossible for the motor power device to quickly switch the transmission mode.

[0005] To this end, we propose a multi-fast switching power device to solve the above problems. Utility Model Content

The rotating block 19 cooperates with the rotating groove 20 to facilitate the staff to drive the front and rear telescopic cylinders 9 to rotate through other tools, thereby ensuring the smooth power switching.

[0027] An annular groove 12 is formed on the inner wall of each switching cylinder 4, and each annular groove 12 is connected to the threaded groove 10. A support seat 21 is fixedly installed on the outer surface of each switching cylinder 4, and the bottom surface of each support seat 21 is in contact with the upper surface of the base plate 1.

[0031] The working principle of the utility model is as follows; when in use, first connect the rotating motor 18 to the power supply. When the rotating motor 18 cannot work due to power cut-off, it is necessary to manually drive the screw rod 2 to rotate. A tool is used to cooperate with the rotating block 19 and the rotating groove 20 to drive the front telescopic cylinder 9 and the connecting spring 8 to rotate counterclockwise. With the stretching of the telescopic cylinder 9 and the connecting spring 8, the front clamping block 7 can be driven to rotate. At the same time, the ball 11 can be rotated inside the threaded groove 10. Through the guidance of the threaded groove 10, the clamping block 7 can be driven to move to the right. At this time, the clamping block 7 can engage with the transmission rod 5 and push the front transmission rod 5 to move to the right until the front second gear 6 is engaged with the first gear 3. At this time, the ball 11 is fixed in the annular groove 12 and continuously rotates, which can drive the screw rod 2 to rotate clockwise, so that the switching of the power equipment can be quickly completed without the involvement of other structures. , making the power switching of the power equipment more convenient and quick. When the screw rod 2 rotates clockwise, it can drive the rear second gear 6 to rotate counterclockwise. At this time, the rear transmission rod 5 can drive the rear clamping block 7 to rotate, and make the ball 11 enter the threaded groove 10 from the annular groove 12. Through the guidance of the threaded groove 10, it can drive the clamping block 7 to move left, and make the rear telescopic cylinder 9 and the connecting spring 8 shrink. The thrust provided by the compression spring 14 can make the rear second gear 6 and the transmission rod 5 move left until the rear second gear 6 is out of meshing relationship with the first gear 3. At this time, the rotation of the screw rod 2 will not drive the rotating motor 18 to rotate, which can effectively reduce the load during the power switching of the power equipment, making it more time-saving and labor-saving to manually rotate the screw rod 2. When the rotating motor 18 recovers power, the power provided by the rotating motor 18 is used to repeat the above operation to quickly switch the manually rotated screw rod 2 to motor drive.
