Description

Technical Field

[0001] The invention relates to the technical field of cranes inside ships, in particular to a circular frame indoor motorized door crane. Background Art

[0002] The contradiction between the increasing demand for multi-mission payload compartments on modern ships and the lack of suitable transport equipment in the narrow cabin space is becoming increasingly prominent, and there is an urgent need to find advanced and feasible technical solutions.

[0003] The multi-mission payload compartment (MMR) is a variable load internal space used by modern surface ships for operations. It is usually designed to meet different operational needs; for example, the MMR of a large scientific research vessel is usually a circular cabin that needs to accommodate different equipment loads such as large unmanned underwater vehicles (UUVs) and unmanned boats (USVs). These equipment loads vary greatly in appearance, are heavy (usually up to 20 tons), and are large in size (usually over 7 meters). Existing means of transporting loads in the internal cabin are usually manual handling or fixed gantry cranes. It is difficult for manpower to meet the needs of modern heavy-duty mission load transportation and there are safety hazards. The gantry crane has poor space flexibility and cannot operate effectively when encountering working conditions that require turning or lateral movement. Summary of the invention

[0004] In view of the above-mentioned defects in the prior art, a circular frame indoor motorized door crane is provided to meet the needs of lifting heavy-loaded cargo in a narrow cabin.

[0009] According to the above technical solution, at least four sets of rotary power wheel mechanisms are arranged on the base, and the number of the rotary power wheel mechanisms depends on the gantry crane.

[0010] According to the above technical solution, each set of rotating power wheel mechanisms has an independent hub propulsion motor, a full rotating suspension device, a battery and a power distribution control box unit.

The cross section of the frame is arc-shaped, and the curvature of the cross section of the frame gradually increases from both ends to the middle area. The base is fixed to the middle bottom of the upper frame, and a plurality of rotary power wheel mechanisms are distributed on the base.

[0030] In this embodiment, the frame is the main load-bearing part of the gantry crane. The frame adopts the bionic design of the skeleton of crustaceans.

[0033] The structure and principle of Example 2 are similar to those of Example 1, except that: a preferred skeleton structure is provided, the skeleton includes a main beam 4-1 and a secondary beam 4-2, the main beam is arranged horizontally along the length of the gantry crane, and the secondary beams are arranged symmetrically on both sides of the main beam; the secondary beam located on one side of the main beam includes a first curved beam 4-21 and a second curved beam 4-22, the top ends of the first curved beam and the second curved beam are fixedly connected to the main beam, the bottom ends of the first curved beam are fixedly connected to the base, and the bottom ends of the first curved beam are fixedly connected to the base or another second curved beam; the first curved beam is located on a vertical plane perpendicular to the main beam, and the second curved beam extends from bottom to top to both ends of the main beam. At least one first curved beam is provided.

[0034] In the case given in Example 2, there are at least 2 structural forms;

[0037] In embodiments 1-2, at least 4 sets of rotary power wheel mechanisms are arranged on the base, and the number of rotary power wheel mechanisms depends on the gantry crane. As shown in the embodiment in the figure, 6 sets of rotary power wheel mechanisms are arranged on the base, and 3 sets of rotary power wheel mechanisms are arranged on one side of the base.

[0038] In Example 1-2, the rotary power wheel mechanism adopts the existing structure, and each set of rotary power wheel mechanism has an independent wheel hub propulsion motor, full rotary suspension device, battery and power distribution control box unit. During the operation of the gantry crane, each set of rotary power wheel mechanism can match the rotation speed, angle and height of each wheel according to the operation needs to achieve forward, backward, steering, lateral movement, crossing and other actions. Turn signals, warning lights and warning signs are provided on the frame to ensure the safety of personnel operation.

[0041] In Example 1-2, a vehicle control room is provided on the vehicle frame, and the vehicle control room is electrically connected to the lifting equipment and the revolving power wheel mechanism; the movement of the lifting equipment and the revolving power wheel mechanism is controlled in the vehicle control room. A battery and power distribution control box unit 8 is also provided on the vehicle frame. The movement of the on-board cable lifting servo mechanism is controlled by the vehicle control room.
