Abstract
A flexible butt-joint clamp relates to a butt-joint structure of a metal bellows, belongs to the bellows technical filed, and is used for overcoming the defects that the prior flange butt-joint structure has higher requirement to the roundness of the bellows, more bolts are used for connection, the mounting of butt-joint is complicated, the flange is easily knocked during transporting, and the manufacturing cost is high. The utility model is characterized in that: bellows segments which are jointed top and bottom are adopted, a joint end is provided with a pore plate for connecting. Compared with the prior flange butt-joint structure, the utility model changes the rigid connection into the flexible connection, reinforces the connection strength, has lower requirement to the roundness of the bellows, greatly reduces the amount of connecting bolts, is mounted and detached conveniently and rapidly, needs no manufacture of the flange, does not have the problem that the flange is knocked during transporting, and is suitable for butt-joint of metal bellows.
Description
Technical field
The utility model relates to the docking structure of metal bellows, and especially the docking structure of heavy caliber metal bellows belongs to the bellows technical field.
Background technique
On the molding machine of special use, roll out the bellows that ripple just becomes certain-length after roll of steel plate made tubulose, a plurality of fixed length bellowss are docked just form long corrugated conduit.Metal bellows is a kind of flexible structure pipe, has certain shock resistance, can adapt to bigger sedimentation and distortion, compare with traditional concrete reinforced pipe, have that engineering cost is low, civil engineering and section bar install can separate implement, the construction period is short, road surfaces does not have advantages such as expansion joint, be widely used in the fields such as highway culvert, municipal drainage pipeline, underground military sidewalk, municipal various pipeline pipelines.The docking structure of existing metal bellows is, the two ends of every joint bellows have adpting flange, and the initial and end flange of adjacent corrugations pipe links together by bolt.This kind flange docking structure makes to should be corrugated conduit part, flexible metal and become rigid construction; The flange plate of rigid construction will be welded on the pipe end of bellows, and the circularity of bellows is had relatively high expectations; The bolt quantity that connects usefulness is many, and trouble is installed in butt joint; Abutted flange highlights in the bellows periphery, is easy in the transportation process be collided with; A large amount of consumption of the processing and fabricating of flange self and bolt cause cost to increase again; For this reason, the reply flanged connecting structure improves, and makes it overcome above-mentioned defective.
Summary of the invention
The purpose of this utility model provides a kind of flexible docking clip, to overcome the use defective of existing flange docking structure.
The alleged problem of the utility model realizes with following technological scheme:
A kind of flexible docking clip is involutory bellows section up and down, and the orifice plate that connects usefulness is arranged on the involutory termination.
Above-mentioned flexible docking clip, described involutory bellows section up and down, its length is answered 〉=a 2-4 pitch of waves.
Above-mentioned flexible docking clip, described involutory bellows section up and down, its pitch of waves, the depth of convolution are coincide with the bellows that is docked.
The utility model is compared with traditional flange docking structure, become and be rigidly connected to flexibly connecting, strengthened join strength, circularity to bellows requires low, connecting bolt significantly reduces, and installing/dismounting is simple and efficient, need not the processing and fabricating flange, the problem of colliding with in can't bluely transporting is suitable to metal bellows butt joint use.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the plan view of Fig. 1.
The component label is respectively in the accompanying drawing: bellows section, 3-orifice plate, 4-nut, 5-bellows under the last bellows section of 1-, the 2-.
Embodiment
Consult accompanying drawing.To after the central axis cutting, form upward bellows section 1 and following bellows section 2 once short bellows, just become the utility model at the scarfing place at semicircular upper and lower bellows section two ends welding up-hole plate 3.Parameters such as the pitch of waves of upper and lower bellows section 1,2, the depth of convolution are coincide with the bellows 5 that is docked, and length is generally answered 〉=the 2-4 pitch of waves, specifically decides on the caliber of bellows 5, gets higher value when caliber is big.The caliber of bellows 5 can be by 0.5 meter to 3 meters.When butt joint is used, upper and lower bellows section 1,2 is fastened on the initial and end end of the two joint bellowss 5 that need butt joint, makes by nut 4 that upper and lower bellows section is involutory to link together, just finish the butt joint of two bellowss 5.
Between clip and the pipe rubber gasket is arranged, the width 50-80mm of sealing gasket, thickness 5-10mm.
Claims (3)
