Description

Containerized modular combined arm support with large bearing capacity

Technical Field

The invention belongs to the technical field of cranes, and relates to a containerized modular combined arm support with large bearing capacity.

Background

The ultra-large type ring rail crane is generally applied to the field needing extra-large type equipment installation, has the super-strong hoisting capacity which is incomparable with other hoisting cranes, and is mainly applied to the fields of petrochemical industry, nuclear power, maritime work and the like. The arm support is a main bearing part of the crane, and the implementation of the hoisting capacity of the crane is very important in the aspect of the bearing capacity of the arm support. And with the continuous increase of the hoisting capacity of the circular track crane, the length of the arm support is also continuously increased, and the structural form of the arm support has great influence on the flexibility of the arm support. The arm support structure is a combined form of an A-type arm support and a parallel arm support, and reasonable assembly is carried out by adopting a containerized modular arm section design, so that the arm support structure with good stability is formed, and large load can be borne. Meanwhile, due to the structural design of containerization, after the auxiliary supporting structure with special design is added, the detachable container transportation of the arm support can be conveniently realized, the arm support can be conveniently placed and transported with a standard container, a large number of arm sections do not need to be placed into the container for transportation, and the transportation cost is reduced. Meanwhile, the design of other parts also considers the size parameter of container transportation, and can well meet the global transportation of equipment and improve the global competitive capacity of the equipment.

Content of patent

The invention provides a containerized modular combined arm support with large bearing capacity according to practical requirements.

The technical scheme adopted by the invention is as follows:

a containerized modular combined arm support with large bearing capacity is composed of two parts: the basic arm length is the length of the A-type arm support. The device comprises a plurality of components, wherein the components comprise a root hinge lug, a root variable cross-section structure, a root connecting beam structure, a root and standard joint connecting structure, a standard joint structure, an A-shaped arm top connecting beam structure, an A-shaped arm top and standard joint connecting structure, a parallel arm top connecting beam structure and a main arm head structure. All the parts are connected through pin shafts or bolts, so that the connection structure is ensured to have local enough rigidity.

The root of the A-shaped arm support is connected with a root variable cross-section structure 2 through a root hinge lug 1 in a bolt or pin shaft mode, and the root variable cross-section structure 2 is divided into a plurality of sections. The root variable cross-section structure 2 is connected with the root and the standard section connecting structure 4 through the root connecting beam structure 3, the classification of the number of structural sections of the root connecting beam structure 3 is carried out by adopting a bolt or pin shaft connecting mode, and the containerization size depends on the structural size. The root part and the standard joint connecting structure 4 are connected with the standard joint structure 5 through a bolt and a pin shaft, and the A-shaped arm support and the parallel arm support are formed by combining four standard joint structures 5 on one side.

The A-shaped arm top connecting beam structure 6 connects the left side and the right side of the A-shaped arm where the standard knot structure 5 is located at the top of the A-shaped arm. The top of the A-type arm is connected with the standard joint connecting structure 7 through a bolt and a pin shaft to be connected with the standard joint of the parallel arm support, so that the structural form of the A-type arm support is transited to the structural form of the parallel arm support. At the top of the whole arm support, a parallel arm top connecting beam structure 8 connects the left side and the right side of the parallel arm support together in a bolt and pin shaft mode to form an integral structure. The main arm head structure 9 is a single modular arm head structure.

The standard knot connecting structure 5 is connected on two sides by designing an auxiliary supporting structure 10. The auxiliary support structure 10 has standard connection corner fittings of a standard container structure, facilitating arrangement by container arrangement.

The combined mode of four arm sections is adopted on one side of the A-shaped arm and the parallel arm, and the high bending resistance and torsion resistance cross section capability is formed on the premise that the size of the single arm section can conveniently meet the requirements of road transportation and ocean ship transportation. Meanwhile, the structural size of a single arm section does not belong to an overweight and oversized part in the transportation process, and the transportation is convenient. For a single arm section, the two ends of the arm section are connected with corresponding fixed structures, so that each arm section has the size parameters of a standard container. The crane with the large-bearing-capacity arm support has global operation capacity, a large number of arm support standard sections adopt the requirement of realizing standard containerized ship transportation, standardized container placing and transportation can be realized after an auxiliary supporting structure is added, a single arm section is not required to be placed into a container, the single arm section and the standard container can be conveniently placed and transported at the same time, and the transportation cost is reduced to a great extent.

The main arm adopts an A-shaped structure in the basic length, as shown in figure 1, the root of the A-shaped arm support is large in size, and meanwhile, the lateral stability of the arm support is improved, so that the super-tonnage lifting capacity can be realized under the condition of the basic arm length. The single-side arm support of the A-type arm is assembled in a four-arm support mode, the situation that the transportation is affected due to the fact that the single-side arm support is overlarge in structural size can be avoided, and the arm support is very convenient to assemble and disassemble on the premise that the carrying capacity is high. When the arm is long, the arm support is lengthened by combining the parallel arm supports on the basis of the A-type arm support, and similarly, the combination form of four arm supports is still adopted for the single-side arm support of the parallel arm support. Through the combination mode of the parallel arms, the long arms can be conveniently assembled, and other connecting parts of the A-shaped arms are reduced due to irregular combination. The arm head adopts independent arm head design, can the different underarm's of root load-lifting capacity, confirms the quantity of required connection arm head, and the reduction arm head quality of trying to get to the greatest extent improves effectual cantilever crane lifting capacity, and its structural dimension satisfies the size of standard container transportation equally.

The combination of the A-type arm support and the parallel arm support is adopted, so that the bearing capacity of the arm support is met, and the arm support is convenient to disassemble and assemble; the containerized modular structure is designed in size, so that the transportation of the disassembled arm support is facilitated; the single-side arm frame is combined by a plurality of small arm frames, so that the single-side arm frame has better bearing capacity and has the advantages of disassembling and combining other arm frames; the auxiliary supporting structure of special design is connected to middle arm section, forms standardized container size structure, can be convenient put with other standard containers, make full use of container boats and ships's transportation space reduces the cost of transportation.
