Abstract
The invention discloses a rigidity-variable structure assembly applicable to lifting. The rigidity-variable structure assembly comprises a lifting beam, a tubular beam, a rigid beam, a dual-lifting-lug support frame and a movable member, wherein the right end of the tubular beam is fixed below the right end of lifting beam, and the left end of the tubular beam is fixedly connected with the rear end of the rigid beam; the dual-lifting-lug support frame is fixed below the left end of the lifting beam; the left end of the tubular beam is rotatably inserted in two lug holes of the dual-lifting-lug support frame; the rear end of the rigid beam is inserted between two lug plates of the dual-lifting-lug support frame; a chute is longitudinally formed in a lower beam face of the rigid beam, a ball screw is arranged in the chute, the upper part of the movable member is in matching connection with the ball screw through a nut, and a hinging hole connected with a load is formed in the lower part of the movable member. The rigidity-variable structure assembly has the advantages that a multi-degree of freedom rigidity-variable system is obtained, and the purpose for changing the rigidity at any time so as to adapt to the environment is achieved.
Description
Technical field
The present invention relates to field of mechanical structure design, especially relate to the stiffness variable structural constituent being suitable for lifting.
Background technology
The equipment of lifting or device, the performance of the rigidity environment lifted in use to its function and performance plays very important effect, when needing the rigidity environment changing lifting, or when needing to simulate certain rigidity environment, then need the various combination of one or more stiffness variable structure to change conforming of rigidity at any time, but yet there are no all relevant reports.
Summary of the invention
The object of the invention is to provide a kind of stiffness variable structural constituent being suitable for lifting.
For achieving the above object, the present invention takes following technical proposals:
The stiffness variable structural constituent being suitable for lifting of the present invention, comprises hoisting beam, and tubular beam, buttress bracing struts, double shackle bracket and movable part form; The right-hand member of described tubular beam is fixed on below the right-hand member of described hoisting beam, and the left end of tubular beam is fixedly connected with described buttress bracing struts rear end; Described double shackle bracket is fixed on below the left end of hoisting beam; The left end of tubular beam rotates and is inserted in two earholes of double shackle bracket; Buttress bracing struts rear end is inserted between two otic placodes of double shackle bracket; The underbeam face of buttress bracing struts longitudinally offers chute along it, and be provided with ball-screw in described chute, the top of described movable part is connected by nut and described ball-screw, and the bottom of movable part is provided with the hinge hole be connected with load.
The invention has the advantages that and realize obtaining multiple degree of freedom stiffness variable system, reach the object that conforms changing rigidity at any time.

Detailed description of the invention
As Figure 1-4, the stiffness variable structural constituent being suitable for lifting of the present invention, comprise hoisting beam 1, tubular beam 2, buttress bracing struts 3, double shackle bracket 4 and movable part 5 form; The right-hand member of described tubular beam 2 is fixed on below the right-hand member of described hoisting beam 1 by attaching parts 7, the left end of tubular beam 2 is fixedly connected with keyhole 9 by key 8 with described buttress bracing struts 3 rear end; Described double shackle bracket (4) is fixed on below the left end of hoisting beam 1; The left end of tubular beam 2 rotates and is inserted in two earholes 10 of double shackle bracket 4; Buttress bracing struts 3 rear end is inserted between two otic placodes of double shackle bracket 4; The underbeam face of buttress bracing struts 3 longitudinally offers chute along it, and be provided with ball-screw in described chute, the top of described movable part 5 is connected by nut and described ball-screw, and the bottom of movable part 5 is provided with the hinge hole be connected with load 6.
During use, when needing the rigidity obtaining Linear-free degree, the movable part 5 on buttress bracing struts 3 is for connecting load 6, and movable part 5 can use manually or motorized motions ball-screw slides on buttress bracing struts.When applying the load 6 of vertical load on movable part 5, because buttress bracing struts 3 has higher composite bending modulus, this load 6 is converted to the twist moment to tubular beam 2 by buttress bracing struts 3, and vertical load 6 is born by bracket 4, elastic deformation is there is in tubular beam 2 under the effect of twist moment, drive buttress bracing struts 3 around the axis rotation of tubular beam 2, thus obtain, with the displacement of load 6 change, material is thus formed a rigidity at the output coupling end of movable part 5.Movable part 5 is in axial sliding on buttress bracing struts 3, the stiffness variable changed with its position can be obtained.
When needing the rigidity obtaining rotary freedom, as shown in Figure 5, assembled in pairs of the present invention is used.Load 6 is connected on the movable part 5 of two buttress bracing strutss 3, and when load 6 rotates, two tubular beam 2 do contrary rotary motion.
