The bed frame 100 uses a power transmission member such as a driven body (not shown) and a coupling (not shown) of the mechanical system 10 on the upper surface to provide power to the driven body so that the driven body can be driven. Any one or more of them may be a structure on which they are seated.

When the mechanical system 10 is a commercial generator or an emergency generator, the driving body may include an engine, and the driven body may include an alternator and a radiator that are rotationally driven by the engine to produce electricity. have.

In addition, when the driven body is directly driven by receiving electricity from the outside, only the driven body may be installed on the upper surface of the bed frame 100 .

The bed frame 100 supports the driven body and the driving body of the mechanical system 10 . That is, the bed frame 100 may be a kind of frame structure having adequate strength and durability to sufficiently support the mechanical system 10 and various components disposed on the upper side.

For example, the bed frame 100 may be a frame structure formed by welding or connecting an integral injection structure, a casting, a plate material of various shapes, a wire rod, a pipe material, a vertical member, a horizontal member, and an inclined member to each other. However, the bed frame 100 is not necessarily limited to the configuration shown in FIG. 1 , and structures having a wide variety of shapes, such as a pad shape capable of supporting the above-described components, may be applied.

The bed frame 100 can be applied to various types of frame structures, but in this embodiment, a pair of first frames 101 and the first frame 101 spaced apart from each other are spaced apart along the longitudinal direction and , may include a plurality of second frames 102 connecting the pair of first frames 101 in the width direction.

Since the vertical member 110 may be fastened to the side of the bed frame 100 by various means such as welding or bolting, it is not limited to a specific means for fastening.

In addition, the vertical member 110 may be disposed to be spaced apart by a predetermined distance along the longitudinal direction of the bed frame 100 , the closer the position where the loads of various mechanical parts located on the upper surface of the bed frame 100 are concentrated. The distance of the vertical member 110 may be set to be close. In other words, it is preferable that the vertical member 110 is more densely disposed at a location where the load is concentrated, so that the load can be more fully supported by the stopper bolt 140 to be described later.

The through hole 110a may be formed to pass through the thickness of each vertical member 110 . The through-holes 110a may be formed in at least one portion of the vertical member 110 , and a plurality of through-holes 110a may be formed corresponding to the number of stopper bolts 140 to be described later.

The fixing members 120 may be formed to be spaced apart in parallel to face one surface of each of the vertical members 110 . That is, the fixing member 120 may be disposed on the ground so as to be spaced apart from the long side side of the bed frame 100 , for example. To this end, the base 130 fixed to the ground may be integrally formed under the fixing member 120 .

Referring to FIG. 5 together with FIG. 4 , the inner diameter d1 of the through hole 110a may be larger than the outer diameter d2 of the body portion 140b of the stopper bolt 140 . When vibration is applied to the mechanical system 10 positioned on the upper surface of the bed frame 100 due to an earthquake in a state in which the body portion 140b of the stopper bolt 140 is penetrated through the through hole 110a, the first frame In the process in which the 101 and the vertical member 110 vibrate (pitching and bouncing) along the front-rear direction, the outer surface of the body portion 140b of the stopper bolt 140 through friction with the inner diameter of the through-hole 110a Displacement along multiple directions is attenuated.

At this time, the buffer plate 220 may be fastened to the lower portion 101b of the first frame 101 through the nut member 240 screwed to the body portion of the fastening bolt 230 .

The body 201, for example, may be formed so that the inner body and the outer body slide to each other, in this case, the outer body is guided by the inner body and may be formed to vertically reciprocate integrally with the buffer plate 220 have.

The elastic member 210 may be a coil spring having a predetermined elastic modulus, and the body 201 reciprocates up and down by the elastic member 210 so that the elastic member 210 is elastically deformed. For this reason, when there is a risk that vibration is applied to the mechanical system 10 when an earthquake occurs, the vibration is damped by the elastic member 210 and the buffer plate 220 of the damping device 200 even when a bounce that is a vertical motion occurs. can

In addition, the number and spacing of the damping devices disposed on the lower surface of the bed frame may be set along the longitudinal direction of the first frame according to the weight distribution according to the position of the generator parts and the intensity distribution of the generated vibration. Accordingly, it is possible to efficiently distribute the overall weight of the mechanical system and the intensity of vibration to increase the efficiency and performance of the mechanical system and reduce the installation cost.

In addition, the outer peripheral surface of the stopper bolt that is through-coupled to the through-hole of the vertical member attenuates the displacement in all directions in the radial direction based on the center of the axis of the stopper bolt, such as the front-rear direction and the vertical direction of the mechanical system due to the action of the through-hole can do it

In addition, since the end of the stopper bolt passing through the through hole of the vertical member performs a buffering action on the side surface of the bed frame, the effect of seismic resistance in the horizontal (left and right) direction by the separation distance between the side surface of the bed frame and the stopper bolt during vibration is reduced. have Here, the seismic function may be maintained by the separation distance between the side surface of the bed frame and the stopper bolt despite the deformation of the bolt, such as bending or cutting of the stopper bolt installed in the horizontal direction.
