The component gantry crane and fine adjustment balance control method thereof disclosed by the application realize high-precision displacement adjustment of components through fine adjustment devices to improve hoisting precision, reduce engineering cost, ensure controllable stress of hoisting ropes and improve safety performance of assembly operation under the premise of improving construction efficiency, and have important popularization value for installation of large subway stations. The component gantry crane comprises a portal, two groups of omni-directional fine-adjustable hoisting trolley devices are movably arranged on the top of the portal, the two groups of omni-directional fine-adjustable hoisting trolley devices respectively vertically suspend adjustable balance hoisting devices, the adjustable balance hoisting devices are installed on a cross beam in the vertical direction, four groups of hoisting device force adjusting devices are installed on the cross beam, and hoisting ropes of the hoisting device force adjusting devices suspend prefabricated components; the omni-directional fine-adjustable hoisting trolley device comprises an upper trolley lifting part borne on a lower trolley running device and an upper trolley translation mechanism; running between the upper trolley translation mechanism and the lower trolley running device is perpendicular in the horizontal direction.

The invention discloses a lifting oil cylinder structure of a carrier, and relates to the technical field of oil cylinder structures. The dust scraping device comprises an oil cylinder shell and a piston rod movably and slidably connected into the oil cylinder shell, a mounting cover is fixedly mounted at the end, close to the piston rod, of the oil cylinder shell, a dust scraping ring is fixedly connected to the top of the mounting cover, and the piston rod is sleeved with the dust scraping ring which is used for scraping dust on the piston rod. Dust, a dust-oil mixture and oil are separated in different spaces through the structure of the inner ring layer and the outer ring layer, oil is adsorbed and dust is isolated through the characteristics of the sponge block, meanwhile, the sponge block is extruded through vertical movement of the extrusion column, the extruded oil is guided back to the contact end of the piston rod and the oil cylinder shell, oil loss is avoided, and dust is isolated. The ash-oil mixture is prevented from entering the oil cylinder shell, and the problem that the service life of the oil cylinder is shortened due to the fact that the ash-oil mixture easily enters the oil cylinder when the carrier is in a high-dust environment is thoroughly solved.

The application relates to the technical field of food processing automation, and discloses an automatic grabbing, placing and whole-machine system, which comprises a visual identification mechanism, a steaming trolley lifting chuck mechanism, an automatic grabbing and sorting mechanism, an automatic placing mechanism, an automatic tearing and replacing mechanism and an empty tray automatic recycling mechanism. The visual identification mechanism identifies the positions of articles through a visual camera and feeds back; the steaming trolley lifting chuck mechanism adjusts the height of a steaming trolley and draws out a steaming tray; the automatic grabbing and sorting mechanism grabs articles and sorts them; the automatic placing mechanism completes article placing and full-tray pushing out; the automatic tearing and replacing mechanism conveys a tray box; and the empty tray automatic recycling mechanism recycles empty trays. The system realizes automatic identification, grabbing, placing and empty-tray recycling of articles, greatly reduces manual operation, improves the operation efficiency of a production line, guarantees production continuity, avoids manual operation errors, improves article placing precision and quality stability, and reduces production cost.

The application relates to the AGV technical field and discloses a transfer device for excavator tooth processing, which comprises an AGV body and a lifting plate arranged on the top surface of the AGV body, two grooves are symmetrically arranged on the top surface of the AGV body, two spring telescopic rods are symmetrically and fixedly installed at the two ends of the inner bottom surface of the groove, a guide frame is fixedly installed at the top end of the two spring telescopic rods, a positioning arm is slidably installed on the inner wall of the guide frame, a clamping plate is rotatably installed at one end of the positioning arm through a rotating shaft I and a torsional spring I, and a reset structure corresponding to the clamping plate is arranged on the side surface of the AGV body. After the AGV trolley lifts the transfer box, the positioning arm automatically extends and the clamping plate is turned by 90 degrees, the driving screw rod of the bidirectional screw is driven through the servo motor, the positioning arm is driven to move towards each other, the transfer box is accurately clamped and placed in the center position of the lifting plate, the problem of gravity center deviation caused by the initial placement of the transfer box is solved, the force balance of the transfer box is ensured, the risk of rollover is reduced, and the foundation for subsequent stable transfer is laid.

The utility model relates to the technical field of feeding frame, concretely relates to a separable feeding frame for high temperature test furnace, including the test furnace for carrying out high temperature test to glass, the placing rack for bearing the glass to be tested, the trolley for transporting placing rack and pushing it to the test furnace, trolley includes base, the bearing frame of liftable installation on base, the push -pull component of slidable wear in the bearing frame one side for drawing placing rack, through the collaborative innovation of separable trolley and high temperature resistant placing rack, has realized the man furnace separation operation of high temperature test process, through push -pull component remote locking, makes operator completely far away from high temperature area, effectively promotes test security, can obviously improve the transfer and test efficiency simultaneously, trolley lifting positioning and placing rack wheel group coordination ensure that equipment fast accurate butt joint, combines separable structure and shortens the furnace body idle time maximum limit.
