DETAILED DESCRIPTION

[0029] In order to make the technical purpose, technical solution and beneficial effects of the present invention more clear, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Embodiment 1:

[0031] A pallet lifting and turning device, such as Figure 1-9As shown, it includes a walking base 1 that is symmetrically arranged on both sides, and the two walking bases are connected by a horizontal square tube 2. A fixed seat 601 and a movable seat 602 are arranged on each walking base 1. The fixed seat 601 is vertically welded or bolted to the walking base 1, and the movable seat 602 is placed on the walking base. A pallet lifting cylinder 605 is also hinged on the walking base. The push rod of the pallet lifting cylinder is hinged to the movable seat 602. The push rods of the two pallet lifting cylinders 605 are synchronously extended and retracted to drive the two movable seats 602 to rise and fall synchronously. In order to ensure that the movable seat can be vertically lifted along the specified trajectory without deflection, two upper and lower swing arms 603 that are parallel to each other are rotatably connected between the fixed seat 601 and the movable seat 602. The fixed seat, the movable seat and the two swing arms together constitute a parallelogram linkage mechanism located on the same vertical plane. That is, since the fixed seat 601 is vertically arranged, the lifting trajectory of the movable seat 602 must be lifted along the vertical plane. In addition, in order to ensure the synchronization of the lifting process of the movable seats on the two walking bases, the two swing arms 603 on the two walking bases are fixedly connected through the connecting pipe 604, so as to realize the rigid connection of the two swing arms 603, which further ensures the synchronization of the lifting of the left and right movable seats 602. Its main function is to drive the pallet to move up and down according to the predetermined trajectory. When working, the pallet lifting cylinder drives the lifting mechanism to move along the track trajectory, so that the pallet can be lifted and lowered according to the predetermined trajectory.

[0032] A pallet tilting shaft seat 701 is installed on the inner side of the movable seat 602, and a double rack swing hydraulic cylinder 703 is installed on the pallet tilting shaft seat. An elastic plate 707 is installed on the lower end of the pallet tilting shaft seat, and a pressure plate 708 is installed on the lower end of the elastic plate. The pressure plate 708 contacts the outer shell of the double rack swing hydraulic cylinder 703. The two sides of the pallet tilting frame 702 are installed on the pallet tilting shaft seat 701 through the rotation of the rotating shaft. The pallet tilting frame 702 can be raised and lowered synchronously with the movable seat 602. And the end of the rotating shaft is connected to the double rack swing hydraulic cylinder 703. Under the drive of the double rack swing hydraulic cylinder, the pallet tilting frame 702 can realize independent flipping together with the rotating shaft. The inner side wall of the pallet tilting frame is installed with a pallet slot 704 formed by two layers of angle steel for loading pallets. The pallet slot can be installed into the pallet slot from the front side edge of the pallet tilting frame. A guard plate 705 is also vertically installed on the rear side of the tray tilting frame 702, and a horizontal support leg 706 is extended backward at the lower end of the guard plate. When the tray tilting frame 702 does not tilt, the horizontal support leg 706 on the guard plate 705 is placed on the horizontal square tube to bear the weight of the tray. The function of the tray tilting mechanism is to tilt the tray so that the electrolyte in the tray falls through the unloading chute onto the lower belt conveyor for transportation.

[0033] A walking trolley for an anode carbon block assembly and unloading station, such as Figure 1As shown, it includes a walking wheel installed at the lower end of the walking base and the pallet lifting and flipping device in embodiment 1. Anti-collision blocks 2 are respectively installed at the front and rear ends of the walking base.

[0034] Finally, it should be noted that the above-mentioned embodiments are only used to illustrate rather than limit the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto, and any equivalent substitutions of the present invention and modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
