Description
Technical field
The utility model is related to pipe parallel connection fixed equipment technical field more particularly to a kind of pipe clamps.
Background technology
Pipe clamp is to be fixed to the tool on holder for single cell to be connected in parallel, or by more pipes, can be with
Pipe relative motion is constrained, tube vibration earthquake intensity is reduced, improves assembly reliability.Fig. 1 is tube assembly schematic diagram, wherein left side
Three hard tubes are connected in parallel by pipe clamp, and intermediate two pipe clamps are in parallel by three pipes and are fixed on holder, and right side pipe clamp will
Two tubes are in parallel.
There are three types of the type pipe clamps common at present：
1, soft rubber damping block pipe clamp
Fig. 2 and Fig. 3 is such pipe clamp structure schematic diagram.The pipe clamp is the pipe clamp structure of three pipes parallel connection, is existing pipe clamp
Common structure.In addition also two-tube, four pipe parallel-connection structures, only illustrate by taking three pipe parallel-connection structures as an example herein.Fig. 2 and Fig. 3 acceptances of the bid
Number 1 is bolt (left and right two), label 2 be spring washer (controlling two), label 3 is that (upper and lower two, material is rubber to damping block
Glue), label 4 be tabletting (upper and lower two panels), label 5 is nut (left and right two).Bolt 1 plays fastening effect with nut 5.Pressure
Piece 4 is stamping steel plate, and the pressure that bolt axial force generates relatively evenly is transmitted to the upper and lower surface of damping block.Hard tube is positioned over
At the circular hole that upper and lower damping block 3 is formed, under the action of bolt power, tabletting 4 compresses damping block 3, and damping block 3 compresses hard tube.Cause
Rubber damping block is softer, and compressive deformation is larger.Rubber damping block compression set causes tabletting 4 to bolt 1 and nut 5
Reaction of bearing weakens, and in order to mitigate this influence, increases spring shim 2.Such pipe clamp is had using soft rubber damping block to be inhaled
Ability of shaking is strong, good with pipe laminating degree, and has good applicability to tubular error, and pipe erection stress is low, is suitable for Fig. 1 institutes
The pipe arrangement shown.
2, rigid plastics damping block pipe clamp
Such pipe clamp is consistent with soft rubber damping block pipe clamp structure, sees Fig. 2 and Fig. 3, be only vibration damping block of material not
Together.Damping block 3 generally uses hard polyurethane material.The material still has compression set characteristic, due to vibration damping block of material
It is hardened, the bearing capacity enhancing under identical compressed thickness, compressive deformation is small, therefore influence of its compression set to bolt axial force
It reduces, anti-loosing effect is better than soft rubber damping block pipe clamp.
3) steel pipe presss from both sides

Block is softer, and bearing capacity is low, and assembly rear bolt axle power is smaller；And blob of viscose damping block has compression set characteristic, blob of viscose dress
It is deformed after matching greatly, compression set influences bolt axial force apparent.Although spring shim has elastic compensating performance, can
Compensation axle power loss to a certain extent, but act on limited.Plain bolt and nut mainly by faying face, frictional force at screw thread
It is locking, this at two frictional force provided by bolt axial force, initial to assemble that rear bolt axle power is smaller, and bolt is easy to loosen, blob of viscose compression
Permanent deformation loses obviously bolt axial force, then is further exacerbated by bolt and loosens.Therefore the shortcomings that soft rubber damping block pipe clamp
It is easy to loosen for bolt, and pipe clamp bolt looseness, pipeline vibration can be obviously improved, and so as to cause pipe crackle, fracture, be easy to draw
The accidents such as give vent to leakage, catch fire.
Rigid plastics damping block pipe clamp, plastics damping block are promoted with respect to blob of viscose hardness, and bearing capacity is high, after assembly
Bolt axial force is promoted.In addition, damping block deformation is small, influence of the compression set to bolt axial force is lowered.Therefore softer
The bolt of rubber damping block pipe clamp loosens risk reduction.But hard damping block is deteriorated to the fitting of pipe, is fitted to tubular error
Answering property reduces, and pipe is susceptible to Planar Mechanisms phenomenon, and the increase of pipe erection stress, reduction pipe and pipe end is caused to connect reliable
Property.
It is big that steel pipe presss from both sides quality, is not suitable for suspension arrangement, using being limited.In addition, steel pipe clamp mouth regulating power is poor, it is right
The tubular applicable ability of pipe further decreases, it is easier to cause the increase of pipe erection stress, what reduction pipe and pipe end connected
Reliability.
