Specific working process:

A transport vehicle is provided on the ground track 51, and the transport vehicle runs on the ground track 51 and transports materials. The shuttle bus frame 12 is driven to move on the first track 11 and the second track 15 is moved to a position corresponding to the ground track 51 where the transport vehicle is located, so that the transport vehicle can drive from the ground track 51 into the second track 15 . Then the shuttle bus frame 12 is driven to move on the first track 11, driving the second track 15 and the transport vehicle to move, so that the second track 15 moves to the target ground track 51, and then the transport vehicle is driven in from the second track 15 The target ground track 51 realizes the function of driving the transport vehicle to move to different tracks.

This embodiment has the following advantages:

The shuttle frame 12 and the second track 15 drive the transport vehicle to move, and by changing the target position of the shuttle frame 12 and the second track 15, the transport vehicle on the second track 15 can move to a different target. The ground track 51 can be adapted to a flexible production model, meet production needs, and achieve the effect of convenient production.

The bottom of the crossbeam 13 and the longitudinal beam 14 are fixed, and the second rail 15 is fixed to the crossbeam 13, so that the position height of the second rail 15 can be effectively reduced, so that the position height of the second rail 15 and the ground rail 51 are the same, so that the transport vehicle can move on the first Move between the second track 15 and the ground track 51. The position height of the second rail 15 is reduced, and the height position of the second rail 15 and the ground rail 51 can be corresponding to each other without digging a hole on the shuttle bus installation surface. Therefore, the shuttle bus and the ground track 51 can be constructed on the same datum plane, eliminating the need to dig a ferry tunnel at the construction site, reducing construction costs, saving the shuttle bus installation cycle, and reducing the installation difficulty of the shuttle bus. The shuttle bus can be applied to sites with terrain restrictions and can be very effectively applied to situations where digging holes is not suitable. It has the advantages of low construction difficulty and good site applicability.

The drive unit drives the drive gear 32 to rotate through the extension shaft 34, so that the drive gear 32 moves on the rack 33 meshed with it, thereby driving the cross beam 13 to move through the drive gear 32 and the extension shaft 34, thereby driving the shuttle frame through the drive mechanism. 12 function to move on the first track 11.

The driving part 37 drives the reducer 38 to operate, so that the output shaft of the reducer 38 drives the extension shaft 34 and the drive gear 32 to rotate, thereby realizing the function of driving the extension shaft 34 and the drive gear 32 to rotate through the drive unit.

The encoder gear 39 is rotatably connected to the longitudinal beam 14 , and the longitudinal beam 14 is fixedly installed with an encoder connected to the encoder gear 39 . The encoder gear 39 is used to connect with the encoder, so that the movement of the driving gear 32 and the shuttle frame 12 can be monitored through the encoder.

When the shuttle car frame 12 moves, the driving gear 32 rotates and drives the encoder gear 39 meshed with it to rotate, so that the encoder can detect the distance the shuttle car frame 12 moves, so that the shuttle car frame 12 can be measured through the encoder. and the second track 15 for preliminary positioning.

By rolling the running wheels 17 on the first rail 11 , the shuttle car frame 12 can move on the first rail 11 , so that the shuttle car frame 12 can be movably installed on the first rail 11 .

The cables are intertwined with each other for ease of use.

By providing an insulating ring between the running wheels 17 and the shuttle bus frame 12, the shuttle bus frame 12 is prevented from being electrified, thereby preventing short circuits and leakage.

When the shuttle bus frame 12 moves to the designated position, the positioning proximity switch 41 contacts the positioning plate 52 fixed on the ground track 51, so that the positioning proximity switch 41 sends out a positioning electrical signal. After the positioning proximity switch 41 sends out a positioning electrical signal, The driving mechanism is controlled to stop operating immediately to realize the positioning function of the shuttle bus frame 12 and the second track 15 . Therefore, it can be determined whether the shuttle frame 12 and the second track 15 are moved in place, thereby improving the positioning accuracy of the second track 15 and ensuring that the transport vehicle can move between the second track 15 and the ground track 51 .

When two shuttle car frames 12 are arranged on the same first track 11, the anti-collision photoelectric sensor 42 is used to monitor whether the distance between the two shuttle car frames 12 is too small. If the distance between the two shuttle car frames 12 is too small, then The driving mechanism is controlled to stop or decelerate immediately to prevent the two shuttle frames 12 from colliding.

During the movement of the shuttle frame 12, if there are obstacles or people on both sides of the movement direction of the shuttle frame 12, the obstacles or persons will contact the pull rope 44 and push the pull rope 44, causing the pull rope 44 to pull. The safety switch 43 causes the safety switch 43 to send out a safety electrical signal, and controls the driving mechanism to stop operating immediately, so that the shuttle bus frame 12 stops moving, which plays an anti-collision function and has the advantage of better safety.

Rotate the nut 24 on the screw 22 so that the nut 24 drives the adjusting plate 23 to move vertically on the screw 22, thereby changing the position and height of the adjusting plate 23, the first track 11, the shuttle frame 12 and the second track 15, thereby adjusting the second Two rails with 15 height features. By adjusting the height of the second rail 15, the second rail 15 can be adapted to ground rails 51 of different heights, thereby improving applicability and having the advantage of conveniently adjusting the height of the second rail 15.
