During process, the derrick body 1 is box, and it is hollow structure that it is internal；Illustrated for ease of distinguishing, two neighboring box-type headframe exists
During aerial docking, the box-type headframe of lower section is lower derrick body 1n, and lower derrick body 1n is welded and fixed with underframe 7, the case of top
Type derrick is upper derrick body 1m, and the quantity of derrick body 1 is 2 in the present embodiment, as shown in Fig. 8 ~ 9.
As shown in fig. 7, after the installation of underframe 7, carry out between lower derrick body 1n and underframe 7 it is aerial dock, utilize
Crane is sling lower derrick body 1n by the first hanger 6, the lower left corner of lower derrick body 1n and the upper left corner connection of underframe 7
Touch, then toward underframe 7 bottom pad lastblock dividing plate be used for support bends portion 42n, beneficial to subsequent installation hinge 2；Instantly derrick sheet
When body 1n is overturn centered on bearing pin 23, lower body 32n below lower derrick body 1n it is spacing under, it is to avoid lower derrick body
The front and rear both sides of 1n misplace with the front and rear both sides of underframe 7 in switching process, along with leading for the bending section 42n in arc
Under drawing, with the continuous upset of lower derrick body 1n so that bending section 42n inserts the inside of underframe 7, under bending section 42n coordinates
Plate body 32n again to switching process in lower derrick body 1n carry out it is spacing, due to by " three-point fix ", lower derrick body 1n
Good with centering effect between underframe 7, constructing operation is simple and convenient, and efficiency of construction is significantly improved.Wherein, due to bending section 42n
It is arc, it is ensured that in the switching process of upper derrick body 1n, inwalls of the bending section 42n all the time with underframe 7 is contacted.
Instantly when the 3rd inclined-plane 12 in derrick body 1n is contacted with the 4th inclined-plane 71 in underframe 7, to lower derrick body
1n carries out weld job with underframe 7, now because the lower body 32n on lower derrick body 1n is under the support of the second support slot 9,
There is gap between the 4th inclined-plane 71 in the 3rd inclined-plane 12 and underframe 7 in lower derrick body 1n, the gap increases welding fluid
With the contact area between lower derrick body 1n, underframe 7 so that the welding between lower derrick body 1n and underframe 7 becomes more
Firmly.Wherein, lower body 32n is semicircle, and the second support slot 9 is by steel bar to bend to semicircle groove-like structure and be welded on bottom
The inwall of frame 7 is made, semicircular lower body 32n and semicircular second support slot 9 so that lower derrick body 1n is being carried out
In the absence of obstruction during upset.
Instantly after the completion of the weld job between derrick body 1n and underframe 7, is pulled down in the cutting of hinge 2 and complete lower derrick
Aerial butt-joint operation between body 1n and underframe 7.4th inclined-plane 71, the 3rd inclined-plane 12 are not only beneficial to lower derrick body 1n and bottom
Upset operation is carried out between frame 7, but also weld job is carried out beneficial between lower derrick body 1n and underframe 7.
When carrying out aerial butt-joint operation between two neighboring box-type headframe, the upper left corner of derrick body 1n and upper derrick instantly
The lower-left angular contact of body 1m, down the upper end pad lastblock dividing plate of derrick body 1n be used for support bends portion 42m, beneficial to follow-up
Hinge 2 is installed；I.e. described upper hinge page 21 is arranged on the left side of derrick body 1, tail end and the derrick body 1 of the upper hinge page 21
Upper end is welded, and the lower hinge page 22 is also disposed at the left side of derrick body 1, tail end and the derrick body 1 of the lower hinge page 22
Lower end is welded, and now the upper hinge page 21 on upper derrick body 1m is docked with a pair lower hinge pages 22 on lower derrick body 1n, then
Bearing pin 23 is inserted into the first pin-and-hole 211 and the second pin-and-hole 221, fastener 231 is welded and fixed with the tail end of bearing pin 23, complete hinge
2 assembling；It is hinged by hinge 2 between the lower left corner of the upper left corner of lower derrick body 1n and upper derrick body 1m, when upper derrick
When body 1m is overturn centered on bearing pin 23, lower body 32m below upper derrick body 1m it is spacing under, it is to avoid upper derrick sheet
The front and rear both sides of body 1m misplace with the front and rear both sides of lower derrick body 1n in switching process, along with the bending in arc
Under the traction of portion 42m, with the continuous upset of upper derrick body 1m so that the inside of the lower derrick body 1n of bending section 42m insertions,
Bending section 42m coordinate lower body 32m again to switching process in upper derrick body 1m carry out it is spacing, due to by the way that " 3 points are determined
Position ", the centering effect between lower derrick body 1n and upper derrick body 1m is good, and constructing operation is simple and convenient, and efficiency of construction is notable
Improve.Wherein, due to bending section 42m be arc, in the switching process of upper derrick body 1m, bending section 42m all the time with go into the well
The inwall contact of frame body 1n.
Instantly when the second inclined-plane 11 in derrick body 1n is contacted with the 3rd inclined-plane 12 in upper derrick body 1m, such as Fig. 9
It is shown；Weld job is carried out with upper derrick body 1m to lower derrick body 1n, now due to the lower body on upper derrick body 1m
Under the support of the first support slot 5n of the 32m on lower derrick body 1n, the second inclined-plane 11 and upper derrick in lower derrick body 1n
There is gap between lower inclined plane in body 1m, the gap is increased between welding fluid and lower derrick body 1n, upper derrick body 1m
Contact area so that the welding between lower derrick body 1n and upper derrick body 1m becomes more firm.Wherein, lower body
32m is semicircle, and the first support slot 5n is bent to semicircle groove-like structure by steel bar and is welded in lower derrick body 1n
Wall is made, semicircular lower body 32m and semicircular first support slot 5n so that upper derrick body 1m is when being overturn
In the absence of obstruction.
Instantly after the completion of the weld job between derrick body 1n and upper derrick body 1m, the cutting of hinge 2 is pulled down i.e. complete
Into the aerial butt-joint operation of two neighboring box-type headframe.Second inclined-plane 11, the 3rd inclined-plane 12 not only beneficial to upper derrick body 1m with
Upset operation is carried out between lower derrick body 1n, but also is welded beneficial between lower derrick body 1n and upper derrick body 1m
Operation.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
