[0022] Example 1:

[0023] like Figure 1-5 As shown, the present invention provides a track-type large workpiece transport device for a painting production line, comprising: a transport vehicle, a ground rail vehicle, a power supply ground rail, a clamping mechanism, a docking mechanism, and a control box 16.

[0024] The ground rail car is installed laterally on the power supply ground rail; the docking mechanism is installed on the ground rail car to support and dock with the transport car, so that the transport car and the ground rail car move synchronously; the clamping mechanism is installed on the transport car to clamp the workpiece; the control box 16 is installed on the ground rail car; the control box 16 is equipped with a controller and a wireless communication module electrically connected to the controller; the ground rail car and the docking mechanism are both driven and controlled by the controller.

[0025] The clamping mechanism is adapted to clamp large, irregular workpieces. The transport vehicle moves the clamping mechanism and the workpiece. The ground rail car moves along the power supply ground rail through the docking mechanism. It is suitable for transporting large, irregular workpieces in the painting production line. At the same time, the docking mechanism can support the transport vehicle, share the weight of the transport vehicle, and improve the stability of the transport vehicle's movement. The wireless communication module facilitates wireless communication between the controller and the remote control center.

[0026] Furthermore, the transport vehicle includes a transport plate 26 and four wheels 25. The four wheels 25 are rotatably mounted at the four corners of the lower side of the transport plate 26. Two parallel tracks 24 are horizontally mounted on the ground. The four wheels 25 travel on the two tracks 24 in pairs. Each wheel 25 is equipped with a limit ring. The limit rings on the two opposite wheels 25 are used to press against the opposite sides of the two tracks 24. The movement of the transport vehicle is achieved through the cooperation between the wheels 25 and the tracks 24, while reducing friction and improving stability. The limit rings prevent the wheels 25 from detaching from the tracks 24.

[0027] Furthermore, an electronic tag 39 is installed on the lower side of the transport plate 26, and a card reader 17 electrically connected to the controller is installed on the top surface of the control box 16. The card reader 17 is used to read the electronic tag 39.

[0028] The electronic tag 39 is read by the card reader 17, which helps the controller determine whether the transport vehicle is one that needs to be moved.

[0029] Furthermore, the clamping mechanism includes two clamping branches and multiple support units; the support units include a support threaded tube 38 and a support screw 36;

[0031] By utilizing the cooperation between the support screw 36 and the support threaded tube 38, the height of the support screw 36 can be adaptively adjusted according to the shape of the bottom of the workpiece, thereby improving the support stability; the rotating handle 37 facilitates the rotation of the support screw 36.

[0033] The T-slot 28, T-slider 27, and adjusting bolt 30 enable the longitudinal sliding adjustable installation of the two clamping adjustment seats 29. The two clamping adjustment seats 29 adjust the tilt angle of the swing rod 33 via the hinge rod 32, so that the ends of each clamping bolt 35 on the swing rod 33 are close to the workpiece.

[0041] The lifting drive motor 19 operates under the control of the controller, and drives the lifting drive screw 40 to rotate through the chain drive pair, causing the docking column 21 to move up and down along the lifting guide tube 20. After the docking column 21 moves up and out of the lifting guide tube 20, its end is inserted into and supported on the docking seat 23, providing an upward support force for the transport vehicle, sharing the weight of the transport vehicle, and at the same time enabling the ground rail car to move synchronously with the transport vehicle. The position sensor 18 helps the controller determine the position. When the position sensor 18 detects the docking seat 23, the controller controls the lifting drive motor 19 to operate.
