Description

Technical Field

[0001] The utility model relates to the technical field of crane safety protection, in particular to a shore crane placement piece anti-smashing device and a shore crane. Background Art

[0002] The most common way of container sea-surveying loading and unloading operations at existing container terminals is to use shore gantry cranes (referred to as shore cranes) as loading and unloading equipment to realize the loading and unloading of container cargo ships. Shore cranes are generally frame-structured cranes, mainly including: two sets of "gantry legs" and a pair of crossbeams (beam frames) erected on the top of the gantry legs, consisting of a trolley, a car and a hoist. The two sets of gantry legs are the sea-side gantry legs and the land-side gantry legs. The beam frame is erected between the sea-side gantry legs and the land-side gantry legs. Each set of gantry legs includes two left and right door posts, and a wheel set is installed under the door posts. During operation, it runs on the ground rails in a direction parallel to the shoreline. Generally, the sea-side gantry leg side is called the front, and the land-side gantry leg side is called the rear. Steel rails are laid on the beam frame, and the trolley runs on the rails along the direction of the beam frame. Through steel wire ropes and hoists, the container or container accessories are hoisted and transported from the cargo ship and the onshore position behind the land-side gantry legs.

[0003] When lifting hatch covers, they can be stacked, with the maximum number of layers generally being four; when placing containers to be transported or processed, containers and hatch covers cannot be stacked.

[0004] During the lifting process, it is inevitable that there will be people or vehicles on the ground in the pre-placement area of ​​the placement parts, and the trolley operator's vision will be blocked by the hoisted placement parts, which can easily lead to dangerous situations.

[0005] At present, the protection measures against smashing mainly include image analysis scheme and laser scanning scheme. However, the image analysis scheme is affected by climatic conditions and has low reliability and a high false alarm rate. As for the laser scanning scheme, due to the different widths of the hatch covers and the actual placement positions on the ground, in order to ensure safety, only the maximum placement range can be used for detection, resulting in ground safety targets (such as reflective cones, etc.) outside the actual placement area of ​​the hatch covers triggering anti-smashing alarms, affecting normal operations, and the actual application value is not high.

[0006] The Chinese invention patent publication with publication number CN108584716A discloses a gantry crane safety protection and operation assistance system. It uses a two-dimensional laser scanner to scan in multiple directions and generate two-dimensional and three-dimensional spatial position information of a trolley, spreader, trailer and related operation boxes. Based on the motion state of the trolley, trolley and spreader, it analyzes the tendency of various types of spatial conflicts in these spatial positions, thereby realizing the discovery of operational hazards. However, the application target of this technical solution is the yard crane of the container terminal, and it cannot be applied to the anti-smash protection of the placement area of ​​the shore crane placement parts. Therefore, it is urgent to develop an anti-smash device that can achieve high reliability and refinement for the placement parts of the shore crane. Utility Model Content

In this embodiment, its height can be set to a height of 1 to 2 meters from the bottom surface, so that the hoisted placement component 60 can be scanned. Figure 1 As shown, the trolley 20 is moved between the cargo ship 01 and the land 01 on the shore, and is basically perpendicular to the moving direction of the large cart 10 (it may not be perpendicular in other embodiments, but is generally not parallel), so as to cooperate with the sling 50 to transfer the placement piece 60 from the cargo ship 01 and the land 01.

[0085] In the specific use process, when performing the operation of lifting the hatch cover, the position of the sling 50 and the lowering speed of the sling 50 are first determined, and then the vertical cross-sectional profile 601 (such as Figure 4 ), and determines whether the object hoisted by the sling 50 is a hatch cover. The determination criteria are: there is a continuous contour curve in the real-time scanning data points within a specific height and width range below the sling 50, and the width of the circumscribed rectangle of the contour curve is not less than the minimum width of the hatch cover. The width of the hatch cover is much larger than other types of hoisted objects such as containers and manned cages, and can be used as a reliable feature for determining the hoisting of the hatch cover. Then, the horizontal cross-sectional profile 602 (as shown in FIG. 6 ) of the target in the pre-placement position area 801 of the placement piece is extracted by the second scanning monitoring component 412. Figure 5 As shown), and determine the actual range 802 of the pre-placement position area of ​​the placement part, and determine whether the target is a hatch cover (if it is a hatch cover, it is normally stacked and placed, if not, it is considered to be a non-placed part). The judgment criteria are: if there is a continuous contour curve located in the pre-placement position area 801 of the placement part in the real-time scanning data point concentration, and the length of the circumscribed rectangle of the contour curve is not less than the minimum length of the hatch cover, then the target is a hatch cover; otherwise, the target is a non-stackable object. If it is determined to be a non-placed part, it is pushed to the warning device 70 through the alarm information sending unit 429 to start the sound and light alarm. Thereby achieving the technical effect of hoisting safety.

[0086] The second scanning monitoring component 412 of the utility model can more effectively judge whether it is a placement piece 60 by reasonably setting the horizontal scanning monitoring and its height, thereby greatly improving the hoisting safety.

[0087] The above-mentioned specific implementation methods, examples and comparative examples of the utility model are all examples and do not have a limiting effect on the protection scope of the technical solution. The fact that there is no comparison of technical features does not mean that there are no outstanding substantive features, but only uses textual descriptions to illustrate the setting method.
