Abstract
The utility model discloses a rigidity-variable structure assembly suitable for lifting. The rigidity-variable structure assembly suitable for lifting comprises a lifting beam, a tubular beam, a rigid beam, a double-lifting-lug bracket and a movable piece, wherein the right end of the tubular beam is fixed below the right end of the lifting beam; the left end of the tubular beam is fixedly connected with the rear end of the rigid beam; the double-lifting-lug bracket is fixed below the left end of the lifting beam; the left end of the tubular beam is rotatably inserted into two lug holes of the double-lifting-lug bracket; the rear end of the rigid beam is inserted between two lug plates of the double-lifting-lug bracket; a sliding groove is formed in the lower beam surface of the rigid beam along the longitudinal direction; a ball screw is arranged in the sliding groove; the upper part of the movable piece is connected with the ball screw in a matching way through a nut; a hinge hole which is connected with a load is formed in the lower part of the movable piece. The rigidity-variable structure assembly suitable for lifting has the advantages that a multi-freedom-degree rigidity-variable system can be implemented, and the aim of changing rigidity adaptation environment at any time can be fulfilled.
Description
Technical field
The utility model relates to Design of Mechanical Structure field, especially relates to the stiffness variable structural constituent that is suitable for lifting.
Background technology
Equipment or the device of lifting, the rigidity environment of lifting plays very important effect to the performance of its function and performance in use, in the time that needs change the rigidity environment of lifting, while maybe needing to simulate certain rigidity environment, need the various combination of one or more stiffness variable structures to change at any time conforming of rigidity, but yet there are no all relevant reports.
Summary of the invention
The utility model object is to provide a kind of stiffness variable structural constituent that is suitable for lifting.
For achieving the above object, the utility model is taked following technical proposals:
The stiffness variable structural constituent that is suitable for lifting described in the utility model, comprises hoisting beam, tubular beam, buttress bracing struts, double shackle bracket and movable part composition; The right-hand member of described tubular beam is fixed on the right-hand member below 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 the left end below 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, in described chute, is provided with ball-screw, and 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 being connected with load.
The utility model advantage is to realize and obtains multiple degree of freedom stiffness variable system, reaches the object that conforms that changes at any time rigidity.

The specific embodiment
As Figure 1-4, the stiffness variable structural constituent that is suitable for lifting described in the utility model, comprises hoisting beam 1, and 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 the right-hand member below 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 ends; Described double shackle bracket (4) is fixed on the left end below 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 ends are inserted between two otic placodes of double shackle bracket 4; The underbeam face of buttress bracing struts 3 longitudinally offers chute along it, in described chute, is provided with ball-screw, and 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 being connected with load 6.
When use, in the time need to obtaining the rigidity of 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 apply the load 6 of vertical load on movable part 5 time, 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, under the effect of twist moment, there is elastic deformation in tubular beam 2, drive buttress bracing struts 3 to rotate around the axle center of tubular beam 2, thereby obtain at the output coupling end of movable part 5 displacement changing with load 6, so just formed a rigidity.Movable part 5 is in axial sliding on buttress bracing struts 3, can obtains the stiffness variable changing with its position.
In the time need to obtaining the rigidity of rotary freedom, as shown in Figure 5, the utility model assembled in pairs is used.6 of loads are connected on the movable part 5 of two buttress bracing strutss 3, and in the time that load 6 rotates, two tubular beam 2 are done contrary rotatablely moving.
