Detailed Description
In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
The invention provides a balance arm lap tool which comprises an installation platform 1, wherein a support assembly is arranged on the installation platform 1, the support assembly is suitable for adjusting the installation position of the support assembly relative to the installation platform 1, so that the balance arm lap tool can be suitable for machining balance arms with different lengths, a positioning seat is detachably arranged on the support assembly, so that the balance arm lap tool can be suitable for machining balance arms with different types, the positioning seat comprises a base positioning seat 31 for positioning a balance arm base 43 and a chord positioning seat assembly for positioning a chord of the balance arm, and the structure of the base positioning seat 31 is the same as the connecting structure of an upper support of a tower crane for connecting the balance arm base 43.
It should be noted that the balance arm base 43 is a connection part of the balance arm and the upper support of the tower crane, and is a concentrated intersection point of the component force of the upper part of the whole tower crane, and therefore, the size positioning of the part is very critical. Because the balance arm can produce certain deformation after the welding, and current pendulum is taken the frock and can not pinpoint the balance arm, causes the balance arm dimensional change who processes out too big for balance arm base 43 and tower machine upper bracket can't be installed, need process once more and install once more the balance arm, thereby increased workman intensity of labour and manufacturing cost, reduced production efficiency and installation accuracy. The base positioning seat 31 has the same structure as the connecting structure of the upper support of the tower crane, so that the balance arm base 43 can be accurately positioned in size, the size change of the balance arm base 43 caused by welding deformation is reduced, the processed balance arm base 43 can be well installed with the upper support of the tower crane, the production efficiency and the installation precision can be greatly improved, and the labor intensity and the production cost of workers are reduced.
