Technical Field
[0001] This invention belongs to the field of railway locomotive and rolling stock production and maintenance technology, specifically a safety gantry robot with pallets for railway locomotive and rolling stock production. Background Technology
[0002] Currently, most gantry robots in railway locomotive depots, rolling stock depots, locomotive factories, and rolling stock factories lack fall protection devices. Instead, they rely on ground barriers to physically isolate personnel. However, in the event of a fall, they could still damage equipment below, posing a significant safety hazard. While a very small number of gantry robots are equipped with fall-protection pallet trolleys on the main carriage, where the trolley moves under the workpiece after it has been lifted to its final position, this structure is complex and requires a large amount of space. Summary of the Invention
[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a safe gantry robot with pallets for railway rolling stock production, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a workshop 1 of a railway locomotive depot, rolling stock depot, locomotive factory, or rolling stock factory includes a longitudinal track 1X, a workpiece 2, and a gantry robot 3. The gantry robot 3 includes a large vehicle 3A, a small vehicle 3B, a lifting device 3C, an opening and closing pallet 3D, and a gripper device 3E. The large vehicle 3A includes a large vehicle body 3A1 and a transverse track 3A2 installed on the large vehicle body 3A1. The large vehicle body 3A1 can move longitudinally on the longitudinal track 1X. The small vehicle 3B includes a small vehicle body 3B1 that can move laterally on the transverse track 3A2. The lifting device 3C includes a lifting column 4, which includes a fixed column 4A and a movable column 4B that can move up and down on the fixed column 4A. The fixed column 4A is installed on the trolley body 3B1, and the gripper device 3E is fixed to the bottom of the movable column 4B when it is in the lowest position. The opening and closing pallet 3D includes an opening and closing device 3D1 and a pallet 3D2. The opening and closing device 3D1 is installed at the bottom of the trolley body 3B1. When the gripper device 3E grabs the workpiece 2 and raises it to the highest position, the pallet 3D2 is closed by the opening and closing device 3D1. The pallet 3D2 is located at the bottom of the workpiece 2, which can prevent the workpiece 2 from falling. When the pallet 3D2 is opened by the opening and closing device 3D1, the pallet 3D2 does not affect the lifting and lowering of the workpiece 2.
[0005] As a further aspect of the present invention: the movable column 4B includes a starting column 4B1, an intermediate column 4B2 and a final column 4B3. The starting column 4B1 can move up and down on the fixed column 4A, the intermediate column 4B2 can move up and down on the starting column 4B1, the final column 4B3 can move up and down on the intermediate column 4B2, and the gripper device 3E is installed at the bottom of the final column 4B3.
[0006] As a further aspect of the present invention: the trolley body 3B1 includes a trolley column 3B1A, and the opening and closing tray 3D includes a horizontal tray device 5. The horizontal tray device 5 includes a tray frame 5A, a tray guide rail 5B, a horizontal tray 5C, and a horizontal drive 5D. The tray frame 5A is installed at the bottom of the trolley column 3B1A, and the tray guide rail 5B and the horizontal drive 5D are both installed on the tray frame 5A. The horizontal drive 5D enables the horizontal tray 5C to open and close on the tray guide rail 5B.

The guide rail frame 6A, including the chain guide rail, is fixed on the trolley body 3B1. The chain 6B can run on the chain guide rail through the chain drive 6D. The support strip 6C is installed on the chain 6B to form the roller shutter support plate. When the support strip 6C is below the workpiece 2, it can prevent the workpiece 2 from falling. When the roller shutter support plate is rolled up, it does not affect the lifting and lowering of the workpiece 2.
[0013] As a further embodiment of the present invention: the opening and closing pallet 3D includes a swing pallet device 7, which includes a swing frame 7A, a swing pallet 7B, a hinge pin 7C, and a telescopic electric cylinder 7D. The swing frame 7A is installed on the bottom of the trolley body 3B1.
