[0001] The utility model relates to the technical field of cranes, in particular to a new type of hook gantry crane. Background Art
[0002] Gantry cranes are transportation equipment for large-tonnage equipment and materials in domestic railway bureaus and are widely used in each railway bureau. Since there is currently no lightning protection and grounding device for gantry cranes, when encountering heavy rain during use, construction usually stops, extending the construction period. During construction and testing in thunderstorm weather, gantry cranes have been struck by lightning and lightning has been introduced into the power distribution room, causing faults such as the burning of the low-voltage side circuit, which has attracted domestic attention.
[0003] A hook gantry crane is a gantry crane with a hook as the main lifting tool. It mainly consists of cylindrical wheels, buffers, block brakes, steel ropes, cast pulleys, cast drums, etc. Some equipment is also equipped with a variety of special hook tools for special operations. In hydropower stations, it can be used not only for installation operations but also for hoisting and opening and closing valves; in container terminals, it is used for stacking or directly loading and transporting containers; in shipyards, it is used for assembling the hull on the shipbuilding berth. There are usually two lifting trolleys, one equipped with two main hooks and the other equipped with one main hook and one auxiliary hook to facilitate the flipping and hoisting of large hull segments.
[0004] The hook gantry crane has a large span and lifting capacity, is suitable for operating across several containers. In addition, it has a compact structure, light weight, energy-saving, and low noise, and is suitable for operating in a limited factory building space. Content of the Utility Model
[0005] The purpose of the utility model is to provide a new type of hook gantry crane with a compact structure and light weight, which is suitable for operating in a limited factory building space. It can not only get closer to the front operation but also has a higher lifting height, effectively increasing the working space of the existing factory building.
[0006] The utility model provides a new type of hook gantry crane, including a gantry. A tonnage plate is provided on the gantry. A platform is provided above the gantry. A lifting trolley is provided in the middle above the gantry. A driver's cab is provided on the right side below the gantry. A control room is provided on one side of the driver's cab. A trolley limit device is provided on one side of the gantry. A wind and lightning measurement device is provided on one side of the lifting trolley. A traveling bogie is provided below the gantry. A large vehicle anchoring device is provided in the middle of the traveling bogie. A container lifting tool is provided directly below the gantry. The control room includes an electrical room and a management room. A welded anchoring pit is provided below the large vehicle anchoring device.
[0007] Preferably, the number of tonnage plates is two, and the tonnage plates are respectively located on the front and back of the platform.
[0008] Preferably, the number of the traveling bogies is four.
[0009] Preferably, the gantry is provided with a trolley power supply and a crab power supply. The trolley power supply is located on one side of the gantry, and the crab power supply is located above the gantry.
[0010] Preferably, the number of the welding anchor pits is four.
[0011] Preferably, a ladder is provided under the platform, and a railing is provided above the platform.
[0012] Preferably, the electrical room is located on the left side of the management room, and the electrical room and the management room are at the same horizontal height.
[0013] Therefore, the present utility model adopts the above-mentioned new type of hook gantry crane, which has a compact structure and is light in weight, and is suitable for operating in a limited factory building space. It can not only get closer to the front operation, but also has a higher lifting height, effectively increasing the effective working space of the existing factory building.
