[0021] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0022] Such as Figure 1 to Figure 3 As shown, the handling trolley rotation mechanism of the vertical lifting type three-dimensional parking garage of this embodiment includes a turntable 1, a rotation drive assembly 2 and a locking assembly 3. The rotation drive assembly 2 is installed in the middle of the handling trolley 100 and is located Below the turntable 1, the turntable 1 is connected to the rotation output end of the rotary drive assembly 2. The locking assembly 3 is located below the turntable 1 and installed on the transport trolley 100, and the locking end of the locking assembly 3 forms a lock with the turntable 1 Cooperate with unlocking. The rotating mechanism of the transport trolley of the vertical lifting type three-dimensional parking garage of the present invention can realize the U-turn and reversal of the vehicle on the transport trolley through the cooperation of the rotating drive assembly 2 and the turntable 1, and can pass through after the rotation of the U-turn and reversal is completed The locking assembly 3 and the turntable 1 form a locked state to prevent relative rotation of the turntable when the handling trolley moves, thereby protecting the rotating drive assembly, and making the control of the entire handling system more stable and simple. It is necessary to drive the turntable 1 to rotate again to achieve When the vehicle turns around on the transport trolley, the lock assembly 3 and the turntable 1 can be unlocked.
[0023] In this embodiment, the rotary drive assembly 2 includes a rotary drive 21, a driving gear 22, a driven ring gear 23, and a support seat 24 fixed on the transport trolley 100. The rotary drive 21, driving gear 22 and driven ring gear 23 are installed Set on the support base 24, the driving gear 22 is connected with the output end of the rotary driver 21, the driven gear ring 23 meshes with the driving gear 22, the output end of the driven gear ring 23 is fixedly connected with the turntable 1, and the diameter of the driving gear 22 is smaller than that of the driven gear The diameter of the ring gear 23 and the engagement of the two form a speed reduction mechanism, which can reduce the configuration requirements of the rotary driver 21.
[0024] In this embodiment, the locking assembly 3 includes a transmission flange 32, a transmission arm 33, a locking arm 34, and a mounting base 31 fixed on the handling trolley 100. The transmission flange 32 is rotatably mounted on the mounting base 31 One end of the transmission arm 33 is hinged with the transmission flange 32, the other end is hinged with the middle of the locking arm 34, the lower end of the locking arm 34 is hinged with the frame of the handling trolley 100, and the upper end is hinged with the locking block 11 provided at the bottom of the turntable 1 In cooperation, the transmission flange 32 is in transmission connection with a lock driver 30. The lock assembly 3 has a simple structure, stable transmission force in the locked state, and low power demand, which can reduce the configuration requirements of the lock driver 30 and ensure the stability of the lock. There is a pair of transmission arm 33 and locking arm 34. A pair of transmission arm 33 and locking arm 34 are separately arranged on both sides of the transmission flange 32. By setting the transmission arm 33 and the locking arm 34 as a pair, the locking can be increased. The dead point improves the reliability of the lock, and can disperse the force of the lock assembly 3, and improve the service life of the lock assembly 3.
[0025] In this embodiment, the upper end of the locking arm 34 is provided with a contact roller 341 for mating with the locking block 11, the side where the locking block 11 meets the contact roller 341 is provided with a contact slope 111, and the contact roller 341 and the contact slope 111 A rolling fit is formed. In the locked state, the two remain in contact. When the handling trolley 100 is working, vibration is unavoidable. This vibration makes the contact roller 341 and the contact slope 111 that remain in contact form a relative movement. Rolling fit can reduce contact wear, so as to ensure the accuracy of locking for a long time.
[0026] In this embodiment, there are two sets of locking components 3, the two sets of locking components 3 are separately arranged at both ends of the lower part of the turntable 1, and the synchronous transmission shafts 4 are installed between the transmission flanges 32 of the two sets of locking components 3. The output end of the lock driver 30 is connected to the synchronous transmission shaft 4, and this structure extends the lock point to both ends of the turntable 1, which can further improve the stability of the lock.
[0027] Such as Figure 4 As shown, in the transport trolley of this embodiment, the transport trolley 100 is equipped with the transport trolley rotating mechanism 200 of the vertical lift type three-dimensional parking garage as described in the above embodiment, and therefore has the corresponding technical effects, which will not be omitted here. Go into details.
[0028] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and transformations obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
