Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-6 As shown, this embodiment provides a large forging transfer trolley that can be quickly positioned, including a mobile trolley 1, a pallet 2, a tilting system, a first support component 6 and a second support component 7.

[0022] In this embodiment, the second support assembly 7 includes two opposing second sleeves 701 and an adjustment system for driving the horizontal radial displacement of the corresponding second sleeves 701. Several second support plates 702 are jointly engaged in the two second sleeves 701, and several second semi-circular grooves 703 are staggered on both sides of the second support plates 702. The adjustment system includes a base frame 704, upright plates 705, guide rods 706, a drive screw 707, a guide ring 708, and a movable nut 709. The base frame 704 is mounted on the support plate 2. Two upright plates 705 are symmetrically fixed to the upper side of the base frame 704. Several guide rods 706 are fixed between the two upright plates 705. The two upright plates 705 jointly support the drive screw 707 with a rotating handle. A guide ring 708 that cooperates with the guide rod 706 and a movable nut 709 that cooperates with the drive screw 707 are fixed to the outer side of the second sleeves 701.

[0023] In this embodiment, the first semi-circular grooves 604 of two adjacent first support plates 603 in the first support component 6 together form a first clamping and positioning groove, and the second semi-circular grooves 703 of two adjacent second support plates 702 in the second support component 7 together form a second clamping and positioning groove.

[0024] In this embodiment, the diameters of the first clamping positioning groove and the second clamping positioning groove are matched with the outer diameter of the cylindrical forging to be transferred.

[0025] In this embodiment, the baffle 602 has a top-ejection hole that corresponds one-to-one with the position of the first clamping positioning groove. The diameter of the top-ejection hole is smaller than the outer diameter of the cylindrical forging to be transferred.

[0026] In this embodiment, the tilting system includes a hinged positioning component 3, a buffer component 4, and a height adjustment drive component 5. The hinged positioning component 3 is disposed between the front end of the pallet 2 and the platform of the mobile trolley 1, the buffer component 4 is disposed between the middle part of the pallet 2 and the platform of the mobile trolley 1, and the height adjustment drive component 5 is disposed between the rear end of the pallet 2 and the platform of the mobile trolley 1.

[0027] In this embodiment, the articulated positioning assembly 3 includes a connecting block 301 fixed on the mobile trolley 1 and a first ear seat 302 fixed on the lower side of the tray 2. The connecting block 301 and the second ear seat 401 are rotatably connected by a pin.

[0028] In this embodiment, the buffer assembly 4 includes a second ear seat 401, a first ear block 402, and a damping telescopic rod 403. There are two second ear seats 401, which are respectively fixed on the mobile trolley 1 and the tray 2. The second ear seat 401 is rotatably connected to the first ear block 402 through a pin, and the damping telescopic rod 403 is installed between the two first ear blocks 402.

[0029] In this embodiment, the height adjustment drive assembly 5 includes a hydraulic drive push rod 501, a second lug 502, a third lug 503, and a connecting plate 504. The cylinder of the hydraulic drive push rod 501 is fixed on the mobile trolley 1. The movable end of the hydraulic drive push rod 501 is equipped with the second lug 502. The third lug 503 is fixed on the lower side of the support plate 2. The two ends of the connecting plate 504 are rotatably connected to the second lug 502 and the third lug 503 respectively through pins.

[0030] The working principle of this embodiment is as follows: Initial state preparation: Move the mobile trolley to a suitable position. At this time, the pallet is in an initial horizontal state. The front end of the pallet is hinged and positioned with the mobile trolley plate through the hinge positioning assembly (connecting block 301 and first ear 302 are rotatably connected by a pin). The buffer assembly (second ear 401, first ear block 402 and damping telescopic rod 403, the second ear block 401 is fixed on the mobile trolley and the pallet respectively and is rotatably connected to the first ear block 402 by a pin, and the damping telescopic rod 403 is installed between the two first ear blocks 402) plays a buffering role in the middle of the pallet. The height adjustment drive assembly (the cylinder of the hydraulic drive push rod 501 is fixed on the mobile trolley, the movable end is installed with the second ear block 502, the third ear block 503 is fixed on the lower side of the pallet, and the two ends of the connecting plate 504 are rotatably connected to the second ear block 502 and the third ear block 503 by pins respectively) is in the initial position to ensure that the pallet is horizontal.

[0031] Adjusting the pallet tilt angle to facilitate overhead crane loading: Depending on the situation of the overhead crane lifting forgings, the hydraulic drive push rod 501 in the height adjustment drive assembly is activated. Its movable end extends or retracts, driving the rear end of the pallet to rise or fall through the connecting plate 504. Since the front end of the pallet is hinged to the moving trolley plate through the hinged positioning assembly, the pallet will rotate around the front end, thereby adjusting the pallet tilt angle to facilitate docking with the forgings being lifted by the overhead crane and achieve rapid loading.

[0032] Placing and positioning the forging: Place the cylindrical forging on the pallet, positioning one end of the forging in the first clamping and positioning groove of the first support assembly (formed by the first semi-circular grooves 604 of two adjacent first support plates 603). Based on the position of the other end of the forging, rotate the drive screw 707 with a handle in the adjustment system. The rotation of the drive screw 707 causes the movable nut 709 to move along the drive screw 707. The movable nut 709 causes the second ferrule 701 to move horizontally and radially along the guide rod 706 via the guide ring 708, thereby adjusting the position of the second support plate 702. This ensures that the other end of the forging accurately falls into the second clamping and positioning groove of the second support assembly (formed by the second semi-circular grooves 703 of two adjacent second support plates 702), achieving precise positioning of the forging and facilitating batch stacking.

[0033] Transferring forgings: Push the mobile trolley to transfer the forgings to the designated location.

[0034] Adjust the pallet tilt angle to facilitate overhead crane unloading: After reaching the designated position, restart the hydraulic drive push rod 501 in the height adjustment drive assembly to adjust the pallet tilt angle for easy docking with the overhead crane and rapid unloading. If it is necessary to remove the forging, the forging can be ejected through the ejection hole on the baffle 602 to facilitate removal from the clamping and positioning slot.

[0035] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to specific implementation methods. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
