Description
Technical field
The present invention relates to the electric vibration table in the environmental mechanics testing equipment, relate in particular to blast connection assembly and assembling method in the electric vibration table cooling air channel.
Background technology
In the total system design of existing electric vibration table,, must force cooling, force cooling can be divided into liquid-cooled and air-cooled electric vibration table because electric vibration table has the heating phenomenon in the course of the work.Usually in the air-cooled electric vibration table of design, the air channel design must be arranged, electric vibration table passes through blast connection with the cooling blower of outside, airduct is connected, as shown in Figure 1, the synoptic diagram of airduct connected mode when being existing air-cooled electric vibration table vertical vibration, airduct 95 is socketed in respectively on the side ventilating opening 922 and cooling blower 96 of existing blast connection 92, when cooling blower is in the exhausting state, the air that heat in the electric vibrating stage body is outwards extracted out along with cooling blower is taken out of together, cold air enters the electric vibrating stage body by air intake web plate 98, thereby realizes air-cooled purpose.
In the vibration test technical field, because test specimen will carry out the vibration of three directions respectively, and test specimen is when carrying out the vibration of three directions respectively, for guaranteeing the true clamping of test specimen, center of gravity often can not change, therefore when doing vibration test, the vertical vibration platform is only arranged not enough, also need to mix horizontal sliding table and can satisfy testing requirements.When electric vibration table band horizontal sliding table uses, because the electric vibration table stage body need be in horizontality, as this moment the shaking table body cooling air port not reversing of position can cause cooling duct to be in case of bending, as shown in Figure 3, connection status when airduct does not change direction when being air-cooled electric vibration table horizontal operation, because this moment, blast connection 91 did not have reversing of position with gland bonnet 93, and electric vibration table to carry out horizontal vibration rotated 90 the degree, so the airduct 95 of this moment has produced airduct knee 951, the bending of cooling duct can increase windage on the one hand, ftractures easily in long-term work situation lower air conduit knee 951 on the other hand.
Also have in the prior art and adopt the position of transposing blast connection to guarantee that airduct is not crooked, as shown in Figure 4, connection status when airduct changes direction when being air-cooled electric vibration table horizontal operation because blast connection 91 has been changed the position with gland bonnet 93, makes airduct 95 be in linear state; Though transposing blast connection cracking problem has solved like this, it is very important that airduct sealing problem and operational issue seem, the hermetically-sealed construction complex operation of prior art, and through causing sealing bad after long-term the use.As shown in Figure 2, it is the synoptic diagram of existing a kind of air-cooled electric vibration table airduct syndeton, when doing horizontal vibration, existing blast connection 91 usefulness screws are fastened on the following ventilating opening 921 of existing ventilator cowling 92 down, gland bonnet 93 usefulness screws are fastened on the side ventilating opening 922 of existing ventilator cowling 92 down, the middle caulking gum layer 94 that is provided with when existing blast connection and existing gland bonnet and ventilating opening 921,922 are fastening; Airduct 95 is socketed in respectively on existing blast connection and the cooling blower 96, and with anchor ear 97 airduct is fastened on the joint; Fixing between the following ventilator cowling air port of common blast connection of this structure and electric vibration table all is the mode that is screwed; , at first need the anchor ear above the airduct is unclamped during blast connection in dismounting like this, take off airduct, and then with spanner fixedly the screw of blast connection pull down, operate more loaded down with trivial details, very inconvenient like this.Especially when electric vibration table when doing horizontal vibration and vertical vibration, blast connection and gland bonnet need frequent replacing position, want repeated disassembled and assembled blast connection and gland bonnet, fixedly the screw of blast connection and gland bonnet carries out frequent dismounting and seems very inconvenient in this case.
As shown in Figure 5, it is the structure of another prior art airduct box fastener formula joint, being connected of blast connection 91 and gland bonnet 93 and existing ventilator cowling 92 side ventilating openings down and following ventilating opening adopts box fastener 99 to realize, blast connection and the middle caulking gum layer 94 that is provided with when fastening with ventilating opening; Though but this structure can solve the loaded down with trivial details problem when changing blast connection and gland bonnet,, can influence the normal use of electric vibrating equipment because the characteristics of box fastener 99 own cause sealing bad easily at the surface of contact place.
