Description

Technical Field

[0001] This utility model relates to the field of tire-mounted gantry crane technology, and in particular to a tire-mounted gantry crane. Background Technology

[0002] Gantry cranes, also known as portal cranes, are mainly used for outdoor loading and unloading operations in ports. Their metal structure resembles a portal frame, with two legs supporting the main beam, allowing them to travel directly on ground-level tracks. The main beam can have cantilever beams extending outwards at both ends. Gantry cranes are characterized by high site utilization, a large operating range, wide adaptability, and strong versatility.

[0003] The tire-mounted gantry crane disclosed in application number 201020101914.4 addresses the problem that ordinary lifting equipment cannot adjust its span. It includes a gantry crane frame with columns and a top beam fixed to the upper part of each column. A tire-mounted traveling system is connected to the bottom of each column. A horizontal telescopic mechanism is installed on the top beam. This mechanism has a horizontal telescopic cavity at one end of the top beam, and a horizontal telescopic rod is fitted inside the cavity. The horizontal telescopic rod and the outer surface of the horizontal telescopic cavity are respectively connected to both ends of a horizontal telescopic hydraulic cylinder. To adjust the height of the gantry crane, a vertical telescopic mechanism is installed on the column. This mechanism consists of a vertical telescopic cavity on the column, within which a vertical telescopic rod is fitted. The outer surfaces of the vertical telescopic rod and the vertical telescopic cavity are respectively connected to the two ends of a vertical telescopic hydraulic cylinder. The span and height of the gantry crane can be changed through the horizontal and vertical telescopic mechanisms. However, the tire-mounted gantry crane will sway during lifting, resulting in poor stability. Furthermore, it is inconvenient for operators to remotely control the movement of the gantry crane.

[0004] Therefore, it is necessary to provide a tire-mounted gantry crane to solve the above-mentioned technical problems. Utility Model Content

[0014] This utility model provides a tire-mounted gantry crane. Multiple drive motors rotate multiple axles and wheels, thus moving the gantry crane. The crane's direction can be controlled by individually controlling the speeds of the drive motors. A lateral movement mechanism moves the load laterally, and a lifting mechanism moves the load vertically. A servo motor drives a screw to rotate, which in turn moves a slider laterally. The slider indirectly drives multiple hooks, which in turn move the load laterally. A positioning plate and connecting plate can be used to mount the lifting mechanism, which can lift the load using multiple hooks. Adjusting the motors, drive gears, and driven gears rotates the vertical shaft and lifting plate, thereby controlling the lifting of the load. The direction is adjusted by a dual-axis motor driving a worm gear, which in turn drives a worm wheel, which in turn drives a horizontal shaft and a winch. The winch moves the strip plate and hook up and down via a wire rope, and the hook moves the load up and down. Equipped with a WiFi module and control module, along with an antenna, the gantry crane can be easily operated and controlled by staff via a wireless local area network. The gantry crane can also be operated and controlled on-site via an operation panel. It is powered by a lithium battery, which can be charged via an external charging cable. Multiple hydraulic cylinders move multiple outriggers downwards to support the device, thereby improving the stability of the lifting operation. Attached Figure Description
