Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of container terminal spreaders, in particular to an electric telescopic balancing spreader for a container terminal. Background Art
[0002] A container terminal refers to a place with clear boundaries that can accommodate the complete container loading and unloading process, including water areas such as harbors, anchorages, approach channels, berths, as well as land areas such as freight stations, storage yards, terminal fronts, office and living areas. A container terminal is a hub for water and land transport. It is a buffer for containerized goods when changing modes of transport, and it is also a point of delivery for goods. Therefore, container terminals occupy an important position in the entire container transportation process. There are many containers stacked in container terminals. When a container needs to be transshipped, a gantry crane will be needed in conjunction with a sling to lift the container.
[0003] Since the hook of traditional lifting equipment is generally pulled by steel ropes, if the objects inside the container are unevenly arranged or affected by airflow when hoisted in the air, the container will easily shake, which will affect the efficiency of the hoisting work and also pose certain safety hazards.
[0004] Therefore, in order to solve the above problems, we need to propose an electric telescopic balancing spreader for container terminals. Utility Model Content
[0005] The purpose of the utility model is to provide an electric telescopic balancing spreader for a container terminal to solve the problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric telescopic balancing spreader for a container terminal, comprising a connecting plate, and also comprising: a connecting rod fixedly connected to both sides of the connecting plate, the front and rear sides of the connecting rod are fixedly connected with an adjusting shell capable of lifting containers of different models, both sides of the inner cavity of the adjusting shell are movably connected with a limit rod for adjusting the lifting position of the container, the surface of the limit rod is provided with a limit hole for adjustment, and the surface of the adjusting shell is provided with a plug hole; an adjusting rod movably connected to one side of the limit rod through a rotating shaft, the bottom of the adjusting rod is movably connected with a connecting seat through a rotating shaft, and the bottom of the connecting seat is fixedly connected with a hook for lifting the container.
[0007] Preferably, a synchronization rod is fixedly connected between opposite sides of the two adjustment rods, and a fixing rod is fixedly connected between the tops of the two limit rods.
[0008] Preferably, a positioning frame for improving the connection tightness with the adjustment shell is fixedly connected to one side of the connecting rod, and the positioning frame is fixedly connected to the adjustment shell at a side close to the adjustment shell.
[0009] Preferably, an insert piece capable of cooperating with the limiting hole to limit the limiting rod is inserted into the inner cavity of the insertion hole, a bolt is threadedly connected to the surface of the insert piece, and one side of the bolt is in contact with the adjustment shell.
[0010] Preferably, a connecting sleeve is fixedly connected to the surface of the fixed rod, and the inner cavity of the connecting sleeve is movably connected to an electric telescopic rod through a rotating shaft, which can expand the lifting position according to different types of containers, and the telescopic end of the electric telescopic rod is movably connected to a movable shell through a rotating shaft, and one side of the movable shell is fixedly connected to the synchronization rod.
[0011] Preferably, a retaining block is fixedly connected to the surface of the synchronization rod, and one side of the retaining block is fixedly connected to the adjustment rod.
[0012] Preferably, a lifting seat for facilitating connection of an external gantry crane is fixedly connected to the top of the connecting plate, and an elliptical lifting hole is provided on the surface of the lifting seat.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] According to the utility model, when the staff needs to transfer the container, they first adjust the length of the limit rod according to the size of the container to be hoisted. When the adjustment is completed, the plug is inserted into the plug hole of the adjustment shell. At this time, the plug will also enter the limit hole of the limit rod. Finally, the bolt is screwed on the rear side of the plug to position the limit rod, so as to achieve the effect of adapting to different types of containers for hoisting. When the hook is clamped with the edge of the container, the telescopic end of the electric telescopic rod will first be squeezed toward the synchronous rod through the movable shell. At this time, the synchronous rod will drive the adjusting rod to move the hook at the bottom of the connecting seat to both sides. When the hook is close to the clamping position of the container, the electric telescopic rod is reset again. At this time, the hook will be completely clamped to the edge stress position of the container. At this time, the gantry crane can start the hoisting work. Through the above hoisting method, the stability of the hoisting work can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS
