It is laid out and is fixed on the marginal position of annular pallet 2.
As shown in Figures 1 to 4, each position-limit mechanism 3 includes: two and holds out against nut 31 and two puller bolts 32；Wherein,
Two hold out against nut 31 and are arranged on annular pallet 2, also, two hold out against the same diameter that nut 31 is located at annular pallet 2
Upwards.Specifically, two hold out against nut 31 may be provided at annular pallet 2 center line the same side and it is same radially.For
Increase 3 use scope of position-limit mechanism, it is preferable that two hold out against nut 31 may be provided at annular pallet 2 inner side edge position and
Outer side edges position is the marginal position of annular pallet 2, with increase two puller bolts 32 along annular pallet 2 move radially away from
From, and then can be with the pre-buried pipeline 5 in hole of a variety of different-diameters of a variety of different wall thickness of sandwiched, to increase the applicable model of the device
It encloses.
Two puller bolts 32 and two hold out against nut 31 and are arranged in a one-to-one correspondence and bolt, to along annular pallet 2
Radial direction moves toward one another or back movement, to realize the clamp or release of the pre-buried pipeline 5 in hole.Specifically, two puller bolts 32
It is disposed opposite to each other, i.e., threaded rod setting or one of the threaded rod of one puller bolt 32 close to another puller bolt 32 are held out against
The head of bolt 32 is arranged close to the head of another puller bolt 32, and the threaded rod of two puller bolts 32 as shown in the figure is close
Setting, is pressed on the inner and outer wall of the pre-buried pipeline 5 in hole, respectively to realize hole by the threaded rod of two puller bolts 32
The limit and fixation of the pre-buried pipeline 5 of mouth.
Nut 31 and two puller bolts 32, which are held out against, by two in present embodiment holds out against principle using bolt is two-way, it can
The pre-buried pipeline 5 in hole to position a variety of calibers and wall thickness, carries out welding dowel.
In the above embodiments, the rotation to be easy to implement annular pallet 2, it is preferable that be additionally provided with rotation on annular pallet 2
Handle hand 8 drives annular pallet 2 to rotate to convert rotary force for push-pull effort.Specifically, rotating handles 8 can be circle
The steel handle of shape structure has a diameter larger than the outer diameter of annular pallet 2 and is coaxially disposed with annular pallet 2, will pass through push-and-pull rotation
Handle hand 8 can drive axis of the annular pallet 2 relative to column 12 around column 12 to rotate, and then drive the hole on annular pallet 2
The rotation of the pre-buried pipeline 5 of mouth, so that the position that the pre-buried pipeline 5 in hole need to weld dowel 6 turns to construction personnel institute in place
It sets.For the push-and-pull for being easy to implement rotating handles 8, it is preferable that the top of annular pallet 2 is arranged in rotating handles 8, to avoid construction
Personnel's sliding rotary handle 8 bend over or other are inconvenient.
To ensure the connective stability between rotating handles 8 and annular pallet 2, it is preferable that rotating handles 8 and annular pallet
It is connected by several along the handle connecting piece that rotating handles 8 are circumferentially arranged between 2, handle connecting piece can connect for L-type
Part 9, one end is connected on rotating handles, and the other end is connected on the lateral wall of annular pallet 2.L-type connector 9 can be for extremely
Lack three and be uniformly arranged along the circumferential direction of rotating handles 8, to further ensure that the connection between rotating handles 8 and annular pallet 2
Stability.For the service life for improving L-type connector 9, it is preferable that L-type connector 9 is arranged radially along rotating handles 8, to hold
By the centripetal force between rotating handles 8 and annular pallet 2.Reinforcing pull rod is limited as L-type connector using 6 tractions in the present embodiment
9, it is uniformly distributed and is fixed between bearing 10 and annular pallet 2.
Certainly, the rotation of annular pallet 2 can also be realized by motor drive mode, i.e., can be equipped with driving on annular pallet 2
Mechanism, to drive annular pallet 2 to rotate, driving mechanism can be the power mechanisms such as motor, so that annular pallet 2 is according to certain
Mode is rotated and is stopped rotating, that is, the angle rotated is according to the angle between two column for welding dowel 6 on the pre-buried pipeline 5 in hole
Degree determines that the static time can determine according to the time of each column welding dowel 6 after rotation.Wherein, on the pre-buried pipeline 5 in hole
Dowel 6 is uniformly distributed i.e. in column arrangement, is respectively listed on same vertical line, along the circumferential equal of the pre-buried pipeline 5 in hole between different lines
Even distribution, therefore can be rotated by the driving annular pallet 2 of driving mechanism systematicness, so that the pre-buried pipeline in hole 5 is according to anticipation side
Formula rotation.
To sum up, the pre-buried pipeline dowel welding turntable device in hole provided in this embodiment utilizes rotation by fixed mechanism 1
The principle for limiting centripetal traction realizes that the entirety of the device is fixed；By the position-limit mechanism 3 being arranged on annular pallet 2, to right
The pre-buried pipeline 5 in hole fixes, and controls and offsets the centripetal force generated when the pre-buried pipeline 5 in hole rotates, prevent from welding
The safety accident of the pre-buried displacement of pipeline 5 in the hole of dowel 6 and generation, so that the pre-buried pipeline 5 in hole is synchronous with annular pallet 2 and puts down
It quietly rotates, avoids the offset or inclination in pre-buried 5 rotation process of pipeline in hole；Pass through 2 bottom of annular pallet 2 and annular pallet
The universal wheel 4 of portion's setting drives annular pallet 2 to rotate relative to fixed mechanism 1 using the controllable principle of the universal rolling of universal wheel 4
To drive the pre-buried pipeline 5 in hole placed on annular pallet 2 to rotate, to carry out the welding of dowel 6 on the pre-buried pipeline 5 in hole, from
And completed on the pre-buried pipeline 5 in hole after the welding of one or a column dowel 6 in construction personnel, made by rotating annular pallet 2
The position of next welding dowel 6 turns to before construction personnel on the pre-buried pipeline 5 in hole, to carry out next or next column
The welding of dowel 6, therefore can avoid the construction personnel after welding one or a column dowel 6 and applied around the rotation of the pre-buried pipeline 5 in hole
Worker person need to only stand in situ, be by the welding for carrying out dowel 6 to the pre-buried pipeline in hole 5 after the rotation of the pre-buried pipeline 5 in hole
Can, a large amount of labour is saved, construction welding efficiency is improved and shortens construction period and construction cost.
