Compared with prior art, the beneficial effects of the present invention are: this easy hanging apparatus of the invention and structure structure
Part collectively forms a Mdof Vibration System, usually requires that the intrinsic frequency of the vibrational system lower than under vibration excitor working frequency
3-4 times of limit.When requiring to make the exciting of upper frequency, the intrinsic frequency of Lift-on/Lift-off System should be reduced as far as possible, makes it below exciting
1/3 or more of frequency.When requiring to make the exciting of lower frequency, vibration excitor should be increased as far as possible and be horizontally mounted between truss and connect
Rigidity.Design feature of the present invention due to being horizontally mounted truss, may be implemented the lifting of different magnitude vibration excitors, and can pass through
The connection relationship between each component is adjusted, determines the rationalization of vibration excitor installation site, guarantees that vibration excitor is stable in the sky, safe
Ground work;The present invention is lifted by realizing stablizing for vibration excitor using easy hanging apparatus, has structure simple, lifting side
Just, flexible adjustment, it is adaptable, convenient for disassembly and assembly, degree of stability is high the advantages that, the stabilization of vibration excitor is lifted with important
Meaning.

The maximum length of tight component is 0.2m, and wherein the maximum length of lock shaft is 0.05m, and the length for locking shell is 0.1m, is owned
The size of screw hole is φ=6mm.The material of hanging apparatus is selected as steel, specific object are as follows: Young's modulus E=2.10 × e11GN/
m2, Poisson's ratio μ=0.3, density is ρ=7800Kg/m3, the mass M of the simple and easy hoisting device is about 35kg.
Specific work process of the invention is:
(1) overlap joint vertical with horizontal truss 1 of sub-truss 7 is passed through into setting buckle type angle at each overlapped joints first
Part connects into a space framework, installs deflecting roller in the bottom of each sub-truss 7.
(2) according to the hoisting height of vibration excitor 3, determination is horizontally mounted the slide downward of truss A, B relative to sub-truss 7
Distance.Further according to the Hoisting Position of vibration excitor, determine the opposite sliding being horizontally mounted in truss between two horizontal profiles C, D away from
From so as to realize primarily determining for vibration excitor Hoisting Position.Sub-truss 7 is vertical with horizontal truss 1, and overlapped that part is put
Big figure is as shown in Figure 9.
(3) by setting positioning bolt 2 and connection bolt 9, being fixedly connected between lifting lug 4 and vibration excitor, lifting lug 4 are realized
Opposite between two horizontal profiles 10 being slidably connected and the relative rotation between screw-threaded coupling component and lifting lug 4 is connect,
According to the Hoisting Position of vibration excitor, determine the opposite sliding distance between horizontal profile, thus realize vibration excitor Hoisting Position into
One step determines.Screw-threaded coupling component is to pass through spiral shell by the lock shaft of the locking shell and two external threads of a disposed thread
Line engagement is constituted.The partial enlarged view connected between lifting lug 4 and screw-threaded coupling component is as shown in Figure 10.
(4) it is nibbled by screw thread between adjusting the opposite sliding distance and lock shaft and locking shell on horizontal truss 1 between lifting lug 4
The length of conjunction makes vibration excitor mandril and excitation point on same plumb line.Realize tuning into the melt for vibration excitor difference Hoisting Position,
It is also able to achieve controllableization of the vertical excitation of vibration excitor simultaneously.
