Description

Technical Field

[0001] The utility model relates to the technical field of double-box container spreaders for yard bridges, in particular to a container guiding auxiliary device for double-box container spreaders for yard bridges. Background Art

[0002] The number of automated yard cranes (tyre cranes, rail cranes) installed is increasing, and the trend towards unmanned operations in automated terminals is becoming increasingly apparent. At this stage, remote control technology is far from achieving the flexibility of manual operation, and the incomplete infrastructure of older terminals inevitably affects the hardware conditions of the site during operation. After years of use, ground subsidence is extremely common in many terminal container yards. When storing containers in locally overloaded areas, the verticality of the containers exceeds the allowable range of existing remote control technology, making it impossible for container hoists to successfully align the containers. This is especially true when lifting double 20-foot containers. After aligning them left and right based on the baseline, when lowering the container, the center lock often fails to align with the lock pin hole in the container's front and back directions due to the lack of a corresponding guide mechanism in the front and back directions. This requires repeated alignment, a flaw that cannot be concealed by the advanced equipment in automated terminals. Utility Model Content

It can be made of steel plates or metal plates, and can be formed by welding or connecting various components. It is arranged on the double-box crane crane center lock 101 and is used for auxiliary alignment of the crane crane center lock and the container hole. It includes a guide part and a mounting part detachably connected to the guide part. The mounting part is connected and fixed to the crane crane center lock 101. The crane crane center lock 101 has a center lock pin 102.

[0023] In one embodiment, the bottom end of the guide portion has a guide slope, which is opposite to the lock in the sling. The guide slope facilitates guidance during alignment. During guidance, the guide portion contacts the upper ends of the front and rear side surfaces of the container, and when continuing to move downward, it is stuck in the upper ends of the front and rear side surfaces of the container, thereby achieving positioning at the upper ends of the front and rear side surfaces of the container.

[0024] In one embodiment, the bottom end of the guide portion is below the bottom end of the middle lock pin 102 of the sling middle lock.

[0025] In one embodiment, each spreader center lock is equipped with one of the yard crane container double-box spreader box guiding auxiliary devices. There are four spreader center locks, two in the front and two in the back, which are symmetrically arranged. The corresponding double-box spreader box guiding auxiliary devices are four, one on each spreader center lock.

[0026] The mounting portion is connected to the center lock of the sling by welding, and specifically can be welded to the outer shell of the center lock of the sling.
