Abstract
The present invention relates to a lifting hook assembly establishing a lifting hook posture detection carrier, and a crane. A section having two side connecting plates is connected in series between a moving pulley component and a lifting hook component to form a three-section lifting hook assembly. A platform surface perpendicular to a lifting force line of action of the pulley component or a straight line parallel to the lifting force line of action of the pulley component may be established on the connecting plates. The advantageous effect of the present invention is: in addition to bearing a lifting weight, the present invention accurately detects a lifting hook deviation posture via the platform surface or the parallel straight line.
Claims8
A lifting hook assembly with lifting hook posture detection carrier, comprising
- a movable pulley component,
- a lifting hook component, and
- a section, connected in series between said movable pulley component and said lifting hook component, wherein a first end of the section is connected to said movable pulley component through a first articulated shaft, and a second end of the section is connected to said lifting hook component through a second articulated shaft,
- wherein the first articulated shaft connecting said movable pulley component and said section is perpendicular to an axial line of a coaxial movable pulley, and the second articulated shaft connecting said lifting hook component and said section is perpendicular to a beam articulated shaft on which said lifting hook is hung;
- wherein when the deviation posture of said lifting hook needs to be detected, said section can be provided with a platform surface perpendicular to a lifting force action line of a pulley block or said section can be provided with a straight line parallel to said lifting force action line of said pulley block.
A lifting hook assembly with lifting hook posture detection carrier, comprising
- a movable pulley component,
- a lifting hook component, and
- an articulated shaft through which said movable pulley component and said lifting hook component are connected together,
- wherein said articulated shaft is perpendicular to an axial line of a coaxial movable pulley, while a beam articulated shaft on which said lifting hook is hung is parallel to said axial line of said coaxial movable pulley;
- wherein when the deviation posture of said lifting hook needs to be detected, said the fender of the movable pulley component can be provided with a platform surface perpendicular to a lifting force action line of a pulley block.
A mobile crane, comprising
- a lifting hook assembly with lifting hook posture detection carrier, the lifting hook assembly including
- a movable pulley component,
- a lifting hook component, and
- a section, connected in series between said movable pulley component and said lifting hook component, wherein a first end of the section is connected to said movable pulley component through a first articulated shaft, and a second end of the section is connected to said lifting hook component through a second articulated shaft,
- wherein the first articulated shaft connecting said movable pulley component and said section is perpendicular to an axial line of a coaxial movable pulley, and the second articulated shaft connecting said lifting hook component and said section is perpendicular to a beam articulated shaft on which said lifting hook is hung.
