As shown in Figure 6 and Figure 7, when pipeline 11 is laid with, multiple present apparatus 10 are arranged at intervals to the laying side of pipeline 11
To the horizontal roller bearing of multiple devices 10 is rotated by the synchronous driving of power drive mechanism, should be arranged at least below every root canal road 11
Three pipe laying units 10；The horizontal roller bearing of multiple pipe laying units 10 under one root canal road, 11 length is artificially adjusted
Certain altitude, and adjust height in the height adjustment range that the present apparatus works and pipeline 11 from initial position to terminal position
Clear is set, pipeline 11 is placed on horizontal roller bearing, straightening pipeline 11 is towards using lateral wink behind the final position of laying
Between clamp system by pipeline 11 or so clamp；Start power drive mechanism, horizontal roller bearing rotation makes pipeline 11 travel forward, works as pipe
When road 11 moves to 10 surface of pipe laying unit, pipeline 11 can hit stretching trip rod, stretch out trip rod at this time by hanging down
Straight ejector pin pushes horizontal pin open out of interlayer pressing plate interlayer, jacks spring abrupt release, effect of the liner in jacking spring
Under bounce, horizontal roller bearing can impinge upon the lower section of pipeline 11, and horizontal roller bearing by downward reaction force and moves upwards at this time
Inertia, so that the cam in liner rotates, cam both ends push clamping plate to be displaced outwardly along dovetail groove and close with outer gallbladder inner wall
(contact surface is respectively provided with tiny groove, increases frictional force, horizontal spring answering for liner of the both ends of them against clamping plate for contact
Position makes clamping plate be detached from the contact with outer gallbladder inner wall and realizes that liner is resetted by the pulling force of horizontal spring), moment locks liner
Lifting is fixed on horizontal roller bearing immediately below pipeline 11, has accomplished that the horizontal roller bearing of multiple pipe laying units 10 is in one
In plane, solve the problems, such as that next laying of root canal road 11 is not at a horizontal plane；The same of pipeline 11 is hit in horizontal roller bearing
When can move downward and compress the portal frame of lateral moment clamp system, locking pin, fastening spring moment are pushed in portal frame decline open
It discharges and thrusting slip frame moves forward along hollow cross, so that sliding sleeve drives lateral roller bearing to hit 11 side of pipeline, impact force is passed
It is handed to the cam that sliding frame to slide in frame to rotate, cam both ends push sideskid mobile simultaneously to the side of hollow cross
It is in close contact (contact surface is equipped with tiny groove, increases frictional force), lateral roller bearing moment is lock onto two sides of pipeline 11,
Accomplish that the lateral roller bearing of multiple pipe laying units 10 is in a plane, has solved the pipeline and paving of next laying
If the problem of good pipeline decentraction, prepare for the welding of subsequent nozzle；When first each pipe laying unit of conduit strike
Stretching trip rod when, can all repeat above-mentioned movement；The pipeline of the subsequent same caliber to be laid with is put into the pipe artificially adjusted
On road laying apparatus 10, pipeline under the driving of power drive mechanism on a horizontal plane, on same straight line by pipeline forward
It is laid with, has accomplished the efficient laying operation of pipeline；Beginning line up plays groove welding after pipeline is routed to position；Since pipeline uses
The present apparatus is laid with, therefore the center in every root canal road all can point-blank need when solving traditional pipelaying work by auxiliary
Assistant engineer has the problem of butt welding, while also solving the problems, such as tube wall mismatch when to pipe welding, has accomplished efficient butt welding
Operation；When the pipeline of laying is aerial pipeline, also ensure that the center of the pipeline that every root bead connects all on straight line,
At this time again pipe laying bracket, conduit saddle when need to only be adjacent to duct bottom installation, it is simple and convenient high-efficient, fundamentally solve
The case where axial force offset deformation is easy to happen when pipe laying work, substantially prolongs the service life of pipeline；Work as laying
Pipeline when being buried pipeline, all on a horizontal plane at the top of pipeline that every root bead connects, use pipe trench bottom level at this time
Degree measuring scale can find out the pipe trench bottom out-of-flatness problem to be treated of each location point.Removing pipe laying unit
Before, an interim locating rod is respectively worn into roller bearing into soil layer from two sides, after dismounting pipe laying unit puts down pipeline, reference
The problem of interim locating rod of two sides removes adjustment pipeline, reduces pipeline or so decentraction, pipe trench bottom injustice detection processing, pipeline
The interim locating rod of two sides greatly reduces the case where working medium pressure inside pipeline loses, also improves with reference to adjustment
The service life of pipeline.
For buried and aerial two kinds of pipeline laying environments, the present apparatus has accomplished that the high efficiency of pipeline is laid with simultaneously, is not necessarily to
Crane carries out auxiliary pipe laying, and the docking of nozzle weld seam is convenient, and all weld bonds are all in same level on pipeline, to guarantee to manage
The axis of operation in road does not shift deformation, improves working efficiency, reduces cost, ensure that construction quality.
With the buried pipeline (specification: φ 1020*12, material of outdoor buried length 120m, buried bottom depth 1.5m
Q235B, single spiral tube road are 12m/ root, and substance is 3.6t/ root) for:
φ 1020*12 buried pipeline is needed with digging machine as requested by pipe canal digging to -1.5m depth * 2m wide, and by pipe trench bottom
Portion's arrangement is smooth, while the earthwork of excavation is closed on stacking.
