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 synchronizes driving rotation by power drive mechanism, and every 11 lower section of pipeline should be arranged at least
Three pipe laying units 10；By the horizontal roller bearing of multiple pipe laying units 10 under 11 length of pipeline, artificially adjustment exists
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 rotation in liner, cam both ends push clamping plate to be displaced outwardly along dovetail groove and close with outer courage inner wall
Contact（Contact surface is respectively provided with tiny groove, increases frictional force, horizontal spring answering for liner of the both end of which against clamping plate
Position makes clamping plate be detached from the contact with outer courage inner wall and realizes that liner is resetted by the pulling force of horizontal spring）, moment locking liner
Lifting makes horizontal roller bearing be fixed on 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 the next laying of pipeline 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, and impact force passes
It is handed to the cam that sliding frame to slide in frame to rotate, cam both ends push sideskid to move 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 to two sides of pipeline 11,
Accomplish that the lateral roller bearing of multiple pipe laying units 10 is in a plane, has solved pipeline and paving that next is laid with
If the problem of good pipeline decentraction, prepare for the welding of follow-up nozzle；When first each pipe laying unit of conduit strike
Stretching trip rod when, can all repeat above-mentioned action；The pipeline for the same caliber to be subsequently 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 beats groove welding after pipeline is routed to position；Since pipeline uses
The present apparatus is laid with, therefore the center of every pipeline all can point-blank need when solving traditional pipelaying work by auxiliary
Assistant engineer has the problem of butt welding, while tube wall mismatch when also solving the problems, such as to weld pipe, has accomplished efficient butt welding
Operation；When the pipeline of laying is aerial pipeline, the center of the pipeline that every root bead connects is also ensured that all on straight line,
At this time again pipe laying holder, conduit saddle when need to only be adjacent to duct bottom installation, it is simple and convenient 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 use pipe trench bottom level at this time all on a horizontal plane at the top of the pipeline connected per root bead
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, it is respectively worn into roller bearing in an interim locating rod to soil layer from two sides, after dismounting pipe laying unit puts down pipeline, reference
The interim locating rod of both sides removes the problem of adjusting pipeline, reducing pipeline or so decentraction, pipe trench bottom injustice detection process, pipeline
The interim locating rod of both 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 ensure 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 of outdoor buried length 120m, buried bottom depth 1.5m（Specification：φ 1020*12, material
Q235B, single spiral tube road are 12m/ roots, and substance is 3.6t/ roots）For：
φ 1020*12 buried pipelines are needed with digging machine as requested by pipe canal digging to -1.5m depth * 2m wide, and will pipe
The arrangement of ditch bottom is smooth, while the earthwork of excavation is closed on stacking.
