Description

A kind of fire fighting tank vibration test fixture
Technical field
It the utility model is related to a kind of dynamic environmental test field, and in particular to a kind of fire fighting tank vibration test fixture.
Background technology
As fire product is quickly grown, many fire products still suffer from the problem of reliability is not high in use.It is suitable The fast development of fire product industry is answered, proposes to formulate the testing standard of specialty and perfect experiment side to fire product therewith Method, solid foundation is provided to improve the reliability of fire product.Fire fighting tank as part essential in fire product, Raising of the raising of its reliability to security against fire has important reuse.For example vehicle-mounted fire fighting tank is arranged on fire fighting truck On, the vibration, impact, the effect for colliding iso-stress run into vehicle travel process is subjected to, can laboratory really simulate Vehicle-mounted stress key suffered by fire fighting tank is whether jig Design is reasonable.Because fire fighting tank is cylindrical structure, while without spiral shell Fixing hole is followed closely, so the design of fixture should consider that fire fighting tank can be fixed, again in view of the transmission of power.Current existing skill Fire fighting tank test fixture typically surrounds quadrangle using four baffle plates and is encapsulated cylindrical fire fighting tank in art, then passes through again Fixture is fixed on vibration table.This method can only play the role of fastening to fire fighting tank, but at the trial can not be rigid by power It is delivered on fire fighting tank, simultaneously as fixture and fire fighting tank are linear contact lay, the fastening force suffered by fire fighting tank surface can not be made uniform, Fire fighting tank and easily deformed simultaneously caused by fastening force.
The content of the invention
The purpose of this utility model is that to solve the above problems and provides a kind of fire fighting tank vibration test fixture, from And solve the problems, such as cylindrical fire fighting tank power rigid of transmission and fastening force deformation in vibration test.
In order to achieve the above object, the technical solution adopted in the utility model is:A kind of fire fighting tank vibration test fixture, bag Include a base, two side plates, four circular arc bearings, three clips.
The base is made up of two root long crossbeams, two tail trimmers and four vertical beams.Using welding between crossbeam and vertical beam Mode connects, and has countersunk head through hole on two root long crossbeams, two tail trimmers, has screwed hole on four vertical beams.
The side plate is by a rectangle bottom plate, a rectangle riser, a rectangle top plate and three vertical trapeziums Supporting plate is formed.Top plate is provided with tapped through hole, and bottom plate is provided with slotted eye.Riser upper end vertical connection top plate, lower end vertical connection bottom Plate, three faces of three supporting plates while connecting bottom board, riser and top plate, L-type structure is formed with this.
The circular arc bearing is concave circular arcs shape.
The clip is arc-shaped, and circular arc both ends are parallel to ground, and there are two through holes at both ends.
Relevant content in above-mentioned technical proposal is explained as follows:
In such scheme, the countersunk head through hole on the long beam and tail trimmer is the mounting hole of fixture.
In such scheme, the side plate is separately fixed on vertical beam.
In such scheme, the circular arc bearing is each attached to the side of two root long crossbeams and two tail trimmers.
In such scheme, the clip is each attached on the top plate of side plate, on the through hole of clip both sides and the top plate of side plate Tapped through hole be spirally connected.
In such scheme, the circular arc bearing is identical with the arc radius of clip.
The beneficial effects of the present invention are:
The utility model is fixed using circular arc bearing and by clip, contact of the fixture with fire fighting tank is changed into face and is contacted, So that the fastening force suffered by fire fighting tank surface is more uniform, will not become while ensureing and rigidly fixing because of fastening force Shape.Base has enough countersunk head through holes simultaneously, it is ensured that the rigid connection of fixture, is being vibrated so as to solve cylindrical fire fighting tank In experiment the problem of power rigid of transmission and fastening force deformation, test reliability is improved.

Specific embodiment:
Below in conjunction with the accompanying drawings and embodiment is described further to the utility model:
Embodiment:Referring to shown in Fig. 1-6:
A kind of fire fighting tank vibration test fixture, including 3, three clips 4 of circular arc bearing of side plate 2, four of a base 1, two.
Referring to shown in Fig. 1-3, the base 1 is made up of two root long crossbeams, 11, two tail trimmers 13, four vertical beams 12.Beam It is connected between beam using welding manner, there is countersunk head through hole, four vertical beams 12 on two root long crossbeams 11 and two tail trimmers 13 On have screwed hole.
Referring to shown in Fig. 1-2 and Fig. 4, the side plate 2 is by a rectangle riser 22, one of rectangle bottom plate 21, one Rectangle top plate 23 and three vertical trapezium supporting plates 24 are formed.Top plate 23 is provided with tapped through hole, and bottom plate 21 is provided with slotted eye.Riser 22 upper end vertical connection top plates 23, lower end vertical connection bottom plate 21, three faces of three supporting plates 24 while connecting bottom board 21, stand Plate 22 and top plate 23, L-type structure is formed with this.
Referring to shown in Fig. 1-2 and Fig. 5, the circular arc bearing 3 is concave circular arcs shape.
Referring to shown in Fig. 1-2 and Fig. 6, the clip 4 is arc-shaped, and circular arc both ends are parallel to ground, and both ends have Two through holes.
