[0053] like Figure 1 to Figure 5 As shown, the utility model provides a quay crane, including a door frame 100, a main beam 200, a self-propelled load-carrying trolley 300, an electrical room 400 and a machine room 500.

[0054] The support beam of the door frame 100 is a spiral tube.

[0055] Preferably, among the support beams of the door frame 100 , the door frame support pipe 140 , the column 110 , and the lower cross beam 120 are designed as spiral pipes.

[0056] The cross section of the main beam 200 is semicircular, with the arc surface of the semicircle facing downward and the flat surface facing upward. The main beam 200 is mounted to the upper cross beam 130 .

[0058] Since the main beam 200 is preferably composed of a rear beam 210 and a front beam 220, the present embodiment is preferably:

[0059] The cross-sections of the rear beam 210 and the front beam 220 are semicircular, with the arc surface of the semicircle facing downward and the flat surface facing upward. The rear beam 210 and the front beam 220 are installed on the upper cross beam 130.

[0061] Preferably, the electrical room 400 and the machine room 500 are separately arranged on the upper cross beam 130 and the rear beam 210 .

[0062] The door frame support pipe 100, column 110, and lower cross beam 120 of the quay crane adopt a full spiral tube structure, and the rear beam 210 and the front beam 220 adopt a semicircular shape, which can effectively reduce wind load and wheel pressure and improve the stability of the whole machine.

[0063] The door frame support pipe 100, the column 110, the lower cross beam 120, the rear beam 210 and the front beam 220 operate as the overall shape support mechanism of the quay crane. Preferably, the self-propelled load-carrying trolley 300 can be placed on the upper surface of the front and rear beams 210 and the front beam 220 as a carrier for the front and rear containers. The machine room 500 and the electrical room 400 are arranged separately, and the machine room 500 is used to place the pitch mechanism and other components.

[0064] The inventor of the present application has made use of the characteristic of a smaller wind coefficient of a semicircular cross-section and has realized the application of a semicircular beam in a quay crane project by studying key technologies such as the arrangement of the semicircular rear beam 210 and the front beam 220, the connection form of the semicircular rear beam 210 and the front beam 220 with the upper cross beam 130, and the semicircular beam suspension trolley.

[0065] The inventor of the present application has realized the application of a full spiral tube door frame 100 in a quay crane project by studying key technologies such as the compression and bending resistance of a door frame support tube 140, a column 110, and a lower cross beam 120, the connection between a spiral tube and a box beam, the connection between a spiral tube and a spiral tube, the connection between a spiral tube and a walking mechanism, and the anchoring connection between a spiral tube and a trolley. The door frame 100 includes a door frame support tube 100 made of a spiral tube, a column 110 made of a spiral tube, and a lower cross beam 120 made of a spiral tube.

[0066] The quay crane of the present invention simplifies the layout of the machine room, and the machine room 500 and the electrical room 400 are arranged separately. The length of the machine room 500 is shortened and the enclosure is eliminated, so that the windward area is reduced, thereby further reducing wind resistance.

[0067] The quay crane of the utility model reduces the wind load and the wheel pressure of the whole machine while ensuring the use performance of the light and small quay crane, and improves the stability and storm resistance of the whole machine.

[0071] The driving mechanism 330 is disposed on the vehicle frame 310 to drive the self-driving vehicle 300 to move on the main beam 200 .

[0072] Preferably, the self-driving load-carrying trolley 300 can adopt an inverted π-type load-carrying type.

[0073] Since the main beam 200 is preferably composed of a rear beam 210 and a front beam 220 , the self-driving load-carrying trolley 300 is driven to move on the rear beam 210 and the front beam 220 .

[0074] like Figure 1 to Figure 5 As shown, as a preferred embodiment of the quay crane of the utility model, the frame 310 is arranged as an inverted structure, and the upper bottom edge of the frame 310 is provided with wheels 311, and the wheels 311 move along the track on the upper surface of the main beam 200, and the lower bottom edge of the frame 310 is located below the main beam 200.

[0075] Preferably, in the overall design of the self-loading trolley 300, the lifting mechanism 320 is arranged on both sides of the track on the trolley frame 310, and the winding drum is arranged parallel to the running direction of the trolley. At the same time, the lightweight moving load allows the configuration of a three-in-one trolley drive motor, making the integrated self-loading trolley 300 more compact, reducing the impact and inertia during operation, and facilitating the design of the overall steel structure.

By adjusting the extension and contraction amount of the cylinders 327, the length of the lifting wire rope 325 is adjusted.

[0080] Preferably, in order to ensure that the winding system 321 has an anti-sway function for the sling 322 during the operation of the self-loading trolley 300, the lifting wire rope 325 between the lifting pulley 324 and the lifting wire rope 325 fixed pulling point maintains a certain angle with the horizontal plane.

[0081] By controlling the extension and contraction of the oil cylinder 327 at the front end of the fixed pull point, the length of the lifting wire rope 325 is adjusted to realize the forward and backward tilting and rotation of the sling 322. The left and right tilting and rotation of the sling 322 is adjusted by controlling the number of turns of the lifting wire rope 325 of the wire rope drum 323 of the left and right lifting mechanisms 320 to adjust the length of the lifting wire rope 325.

[0082] At the same time, the extension and retraction of the oil cylinder 327 can also absorb the force of the cabin hanging, thereby realizing the anti-cabin hanging function.

Among them, the machine room 500 removes the shed structure, which can reduce the wind load, and preferably uses an electric hoist to replace the indoor maintenance crane to simplify the layout and reduce the weight.

[0094] As described above, the present invention simplifies the layout requirements of the machine room 500 and further reduces the equipment deadweight, wind load and energy consumption.

[0095] In summary, this new type provides an innovative light-duty quay crane, which provides the greatest cost-effectiveness, lowest energy consumption and highest safety while ensuring loading and unloading performance.
