Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail.
Embodiment one
As it is shown in figure 1, a kind of blower fan tower barrel attachment structure, including cylindrical upper tower 1 and lower tower 2, general, on
Tower 1 and lower tower 2 have certain tapering, to increase its stability.Described upper tower 1 is fixing with lower tower 2 to be connected, two
The junction of tower is provided with flange arrangement, and described flange arrangement includes, flange circle 3 reinforcement that be connected fixing with flange circle 3
10.Described flange circle 3 is fixing with the inwall of tower to be connected, and is provided with multiple bolt hole, can make upper tower 1 by flange circle 3
It is mutually butted with lower tower 2.Described flange circle 3 is a pair, is separately mounted in upper and lower tower 1,2, the end face of flange circle 3
With tower end flush, after upper and lower tower 1,2 connects, the end face of two flange circles 3 fits.General, single flange circle 3
Often it is segmented into multi-section circular arc blanking, and is spliced.Flange circle 3 is fixing with tower by the way of welding to be connected.
Described reinforcement 10 is fixedly connected between two bolts hole of flange circle 3, and along tower axially inside tower
Extend, and fixing with tower inwall be connected.Reinforcement 10 is fixing with flange circle 3 and tower inwall by the way of welding to be connected.
Bolt 5 is installed in the bolt hole of flange circle 3,5 makes upper and lower tower 1,2 form a fixed connection by tighting a bolt.
For strengthening the intensity of tower junction, the inner circumferential side of described flange circle 3 is additionally provided with holder 4, and described holder 4 is pacified
It is contained in the surface of two flange circles 3, and two flange circles 3 are fixed to clamp.Two flange circles 3 not only by the fastening force of bolt 5,
But also by by the thrust from holder 4.Holder 4 typically uses the metalwork of high intensity, is unlikely to deform, upper and lower
Tower 1,2, by the common effect of bolt 5 with holder 4, connects relatively reliable, effectively prevent bolt 5 and occurs to loosen.
As in figure 2 it is shown, specifically, it is provided with the groove dodging reinforcement 10 in the centre position of holder 4, described groove
Width is close with the thickness of reinforcement 10, and when holder 4 is arranged on flange circle 3, accordingly, the groove of holder 4 is stuck in
On reinforcement 10, make the reinforcement 10 of upper and lower tower 1,2 be stuck in groove, serve the effect of location reinforcement 10,
Under the positioning action of groove, upper and lower tower 1,2 cannot relatively rotate, and therefore, holder 4 serves to have shared and cuts suffered by bolt 5
The effect of shear force.
As it is shown on figure 3, described holder 4 has two clamping end 6 and connects the middle interconnecting piece 7 of two clamping end 6, institute
State clamping end 6 and be stuck in the upper and lower sides of flange circle 3, and contact with each other, to provide certain thrust.Preferably, described two folders
Hold end 6 to be vertically arranged with middle interconnecting piece 7, form straight turning, described middle interconnecting piece 7 and flange circle 3 in both junctions
Inner circumferential side fit, clamping end 6 and middle interconnecting piece 7 are vertically arranged and can preferably outline with flange circle 3 be affixed
Close, to increase contact area.
Being provided with a jackscrew structure 8 at least one clamping end 6 of described holder 4, this jackscrew structure 8 is used for adjusting folder
The pressure that two flange circles 3 are applied by gripping member 4.Described jackscrew structure 8 includes, runs through this clamping end 6 screw thread of threaded engagement
Bar 11 and between this clamping end 6 and flange circle 3 regulating block 12, described threaded rod 11 is parallel with the bolt 5 on flange circle 3
Arranging, described regulating block 12 is connected with threaded rod 11, and regulating block 12 can be made to move up and down by rotating threaded rod 11, regulating block
The side of 12 contacts with flange circle 3 surface, is used for applying pressure.
Owing to threaded rod 11 and holder 4 are threaded engagement, therefore, when rotating threaded rod 11, regulating block 12 will occur
Moving up and down, when regulating block 12 moves to flange circle 3 direction, holder 4 is applied to the pressure on flange circle 3 and will constantly increase
Greatly, and being compressed by two flange circles 3, when opposite direction rotates threaded rod 11, the pressure that holder 4 is applied on flange circle 3 will not
Disconnected reduction, can conveniently dismantle.
Embodiment two
As shown in Figure 4, Figure 5, from the difference of embodiment one, the present embodiment is that the structure of holder 4 is different, the present embodiment
In the width of described holder 4 more than the distance of adjacent two bolts hole, described clamping end 6 extends radially to flange along tower
Region between bolt hole and the tower inwall of circle 3, is provided with the through hole 9 coordinated with bolt hole on clamping end 6, through hole 9
Diameter is slightly larger than bolt hole.Described bolt 5 through the through hole of clamping end 6 and the bolt hole of flange circle 3, and by holder 4 with
Flange circle 3 forms a fixed connection.When mounted, first upper and lower tower 1,2 is docked, then holder 4 is installed, makes holder 4
The bolt hole of through hole alignment flange circle 3, then installs bolt 5, makes holder 4 form a fixed connection with flange circle 3.
Principle of the present utility model is: described holder 4 is rigid member, when it is stuck on flange circle 3, it will thus provide certain
Thrust, make two flange circles 3 fit together closely, and the groove on holder 4 coordinate with reinforcement 10, serves
The effect of location reinforcement 10, therefore, holding frame 4 has been shared the tension suffered by bolt 5 of the upper and lower tower of connection simultaneously and has cut
Shearing stress so that tower connects more firm.Flange circle 3, by the structure-reinforced connection with tower of reinforcement 10, improves
Tower, in the intensity of junction, effectively reduces the cost of overhaul.
The above is embodiment of the present utility model, it is noted that for the ordinary skill in the art,
Without departing under this utility model principle premise, it is also possible to making various deformation and improvement, this also should be considered as this utility model
Protection domain.
