The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, the present embodiment provides a detachable boom 100, which includes two combined arms 110 disposed in parallel at intervals, the combined arm 110 is formed by combining at least two truss arms 120 disposed side by side on a cross section, and the number of the truss arms 120 forming the combined arm 110 is an even number.
First, the distance L between the two combination arms 110 can be flexibly set according to actual needs, and generally, when the width of the formed combination arm 110 is wide in the lateral direction, the distance L is relatively large. By adopting the above mode, the stability between the two combined arms 110 can be increased, and the hoisting is convenient to be smoothly carried out.
Second, the number of the truss arms 120 forming the cross section of the combining arm 110 may be set to two, four, or six, etc., which is not particularly limited in the present application as long as the required hoisting requirements can be satisfied. In addition, it should be clear that the present application adopts the form of the combination arm 110, and is not a simple combination of a plurality of truss arms 120, and after the combination arm is assembled in the above form, the mechanical properties of the combination arm 110 can be greatly improved, so that the combination arm 110 has higher loading capacity.
Thirdly, when there are a plurality of truss arms 120 forming the cross section of the combined arm 110, for example, when there are six truss arms 120 forming the cross section of the combined arm 110, the combined arm 110 may be split as required, that is, one combined arm 110 with six cross sections may be split into two combined arms 110 with two cross sections or four combined arms 110 with cross sections (please refer to fig. 1 and 2), so that a large number of man-hours may be reduced, and the splitting operation is more convenient.
Fourth, the truss arms 120 of the present application may employ a quadrangular prism frame structure or a hexagonal prism frame structure, and when the quadrangular prism frame structure is employed, it is easier to combine the truss arms 120 into the composite arm 110. When the hexagonal prism frame structure is adopted, the number of effective supporting members of the truss arm 120 can be increased in a limited space, which is beneficial to better improving the structural strength of the combined arm 110.
