The orientation showing or position relationship, are for only for ease of description this utility model and simplify description, rather than instruction or hint indication
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The restriction of novel protected scope.
Below by embodiment, this utility model is described in further details.
This utility model provides a kind of exciter support for modal test, including base plate 1, corner post 2, pillar 3, connects
Narrow bars 4 and bolt 5, as described in Figure 1, the side of pillar 3 are provided with chute, connection strap 4 is arranged in described chute, and quilt
It is limited in described chute and slides, corner post 2 is arranged on outside described chute, and connection strap 4 and corner post 2 are connected by bolt 5, bolt 5
When tightening, described corner post 2 can be fixed on any position of pillar 3, and the periphery of base plate 1 connects described corner post 2.
Firstly the need of explanation, chute is T-shaped chute, is arranged on the side of pillar 3, and connection strap 4 adaptation is arranged on T-shaped
The bottom of chute, and mutually drawn close by chute side but there are two margin systems in gap, as shown in Figure 1 or 2, bolt 5
One end is connected on connection strap 4, and the other end passes through above-mentioned gap and protrudes chute, for connecting corner post 2.In addition, having one on base plate 1
Group mounting-positioning holes are used for installing vibrator 6, and vibrator 6 is fastened on base plate 1 available bolt, as shown in Figure 2.
In the present embodiment, corner post 2 is vertically welded in the corner of base plate 1, and pillar 3 adopts industrial aluminum profile to process.
It is understood that for reaching the level still ensuring that vibrator when irregular place is using this device, institute
State the quantity all not lower than 3 of the quantity of corner post 2 and pillar 3, such as this gives four corner posts and four pillars, when
So corner post 2 can not also wait with the quantity of pillar 3, you can so that part corner post is hanging, in an alternate embodiment, corner post
2 are preferably evenly arranged along the circumference of base plate 1, and the base plate that such as the present embodiment is given is square structure, then corner post 2 is generally located on
Four angular position of square floor, for another example base plate if round, and be disposed with three corner posts, then three corner posts mutually it
Between in 120 ° distribution.
In the present embodiment, corner post 2 is string configuration, its with back plate connections can be corner post end or
The centre of corner post, as shown in figure 1, corner post 2 is connected with base plate 1 preferably by end, hereinafter referred to as optimal case it is possible to understand that
, corner post 2 is bigger with the contact area of pillar 3, and the area for connecting bolt that it provides is bigger, and bolt is more, in spiral shell
Under the equal screwing force of bolt, corner post 2 is bigger with the interaction force of pillar 3, and frictional force is also bigger such that it is able to more stable props up
Support is arranged on the vibrator on base plate, for this reason, in the present embodiment being connected the end of corner post 2 with base plate 1, can ensure corner post 2
Have under maximal friction with pillar 3, base plate 1 has bigger range of accommodation, illustrate, if strut lengths are 1m, from
Bottom is 0-1m to high-end scale mark, and corner post length is 0.5m, is adjacent to completely in the length of this 0.5m ensureing corner post 2 and is propping up
When on post, using the optimal case selected by the present embodiment, the range of accommodation of base plate is 1m, that is, be equal to the length of pillar, and incite somebody to action
When base plate is with being connected in the middle part of corner post, its range of accommodation is only 0.5m, and that is, base plate 1 can be in the model of mount dial 0.25m-0.75m
Enclose interior regulation.Above-mentioned using the premise ensureing base plate 1 range of accommodation with 1m during optimal case be, the tow sides of base plate 1
Corner post 2, unanimously such that it is able to ensure when being installed to corner post 2 on pillar 3, both can be put by structure away from one end of base plate
Putting into is higher than the horizontal plane that base plate 1 is located in height, as shown in Figure 1 it is also possible to put corner post 2 away from one end of base plate
Become and be less than the horizontal plane that base plate 1 is located in height, as shown in Figure 2.
In the present embodiment, described corner post 2 and connection strap are provided with multiple bolts hole, and by multiple bolt connection institutes
State connection strap 4, the length of corner post 2 is typically consistent with the length of connection strap 4, when multiple bolts are tightened jointly, can by base plate more
Plus be firmly fixed on pillar 3.
In the present embodiment, as it was previously stated, described pillar 3 is elongate configuration, its at least two chutes are arranged on pillar 3 phase
On adjacent side, described corner post includes two faces each other with angle and constitutes, and two faces become placed against has chute
The adjacent side of pillar 3 on, in the present embodiment, as shown in Figure 1 or 2, pillar 3 is cuboid, and four sides all have cunning
Groove, wherein, is provided with connection strap 4 in the chute on two at least adjacent sides, in the same manner, the matched angle being fixedly connected
Post 2 is to be made up of two orthogonal panels, and arbitrary panel is adjacent to and is connected on the adjacent side of above-mentioned two.
It is understood that corner post includes two faces each other with angle constituting, this angle is according to pillar 3
Fixed, in alternate embodiment, if the section of pillar 3 is regular hexagon, above-mentioned angle is 120 degree.
In the present embodiment, the outer surface of the side with chute of described pillar 3 is provided with scale mark, scale mark
Prolong pillar 3 axial arranged, conveniently positioning and use.
The support being provided by the present embodiment, each pillar 3 can individually adjust to adapt to different bases it is ensured that base plate 1
Level, irregular local especially prominent using this advantage.This utility model structure is simple, solid and reliable, draws materials easily, raw
Produce low cost.This utility model is lightweight, disassembled, is easy to carrying, deposits.
Last it is to be noted that：Above example is only in order to illustrating the technical solution of the utility model, rather than it is limited
System.Although being described in detail to this utility model with reference to the foregoing embodiments, those of ordinary skill in the art should manage
