Detailed description of the invention
The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
Upper and lower, left and right in below describing all are as the criterion with diagram, and actual installation position is by that analogy.
With reference to Fig. 1, Fig. 2, Fig. 3, the structure of the present invention is, including connecting seat 2, connects seat 2 lower surface by multiple bolts 8
Fix with derrick body 1 and be connected, connect and be symmetrically installed with crownblock beam A3 and crownblock beam B9, crownblock beam A3 and crownblock beam B9 on seat 2
Four limits are equipped with two governor motions 5 (every limit is equipped with two governor motions 5, four limit total of eight governor motions 5), each tune
Joint mechanism 5 is correspondingly arranged on a support 13 on connection seat 2, is welded on connection seat 2 behind all supports 13 location；Crownblock beam
A3 and crownblock beam B9 is respectively by 8 governor motions 5 of each self installation, it is achieved position, left and right before and after crownblock beam A3 and crownblock beam B9
Put regulation；After position adjustments completes, crownblock beam A3 and crownblock beam B9 lower surface are connected with being connected seat 2 by multiple bolts 8 respectively
Fixing (location)；
Being provided with head pulley group assembly A7 and fast line wheel assembly A6 on crownblock beam A3, head pulley group assembly A7, fast rope sheave are total
A6 is become to form a whole with crownblock beam A3；Head pulley group assembly B11 and fast line wheel assembly B10 is installed on crownblock beam B9, main
Assembly pulley assembly B11, fast line wheel assembly B10 form a whole with crownblock beam B9；
Four auxiliary pulleys 4 respectively it are disposed with and an anti-collision sleeper 17 is (the most total connecting the corresponding each well head of seat 2 lower surface
Have eight auxiliary pulleys 4 and two anti-collision sleepers 17), all of auxiliary pulley 4 is all fixedly welded on connection seat 2 lower surface,
Two anti-collision sleepers 17 between four auxiliary pulleys 4 on every limit, wherein four auxiliary pulleys 4 and 17, anti-collision sleeper
Below crownblock beam A3, four additional auxiliary pulley 4 and another one anti-collision sleeper 17 are positioned at below crownblock beam B9.
With reference to Fig. 4, the structure of each governor motion 5 is, including being arranged on the support 13 connected on seat 2, each support 13
In in the horizontal direction thread bush be connected to a leading screw 15, have circular hole radially in the outer end of leading screw 15, be used for inserting regulation work
Tool carrys out rotational lead screw 15, is provided with a support plate 12 in the inner of leading screw 15, and leading screw 15 and support 13 thread bush interface are provided with lock
Jack panel 14, support plate 12 one end and crownblock beam A3 or the support seat apical grafting of crownblock beam B9 alien invasion, support plate 12 other end with
Leading screw 15 screw thread is socketed, it is achieved support plate 12 is circumferentially positioned by lock-screw 16 and leading screw 15.
It is strip with connecting the corresponding bolt hole installing bolt 8 between seat 2 with reference to Fig. 5, crownblock beam A3 or crownblock beam B9
Shape via, and the most vertical, it is achieved sky vehicle frame and the change regulation being connected seat 2 position all around, it is always ensured that bolt 8
Installation fix.
The regulation process of apparatus of the present invention is,
1) vertical or horizontal it is individually moved
With reference to Fig. 2, when needing to regulate (top in Fig. 2) when crownblock beam A3 is moved rearwards by, move up as required
Distance and the pitch of leading screw 15 calculate (2) leading screw 15 above crownblock beam A3 respectively and retreat the number of turns that upper transfer is dynamic.Pine
The locking nut 14 of two governor motions 5, rotational lead screw 15 above Kaitian's bicycle beam A3, make to move on a support plate 12, until it reaches meter
Calculation value, unclamps the locking nut 14 of two governor motions 5 on the right side of crownblock beam A3, slightly rotational lead screw 15 subsequently, makes a support plate 12
The most slightly move；Then two governor motions 5 below regulation crownblock beam A3, make to move on a support plate 12, promote crownblock beam A3 upwards
Mobile, until a support plate 12 of two governor motions 5 above contact crownblock beam A3, finally lock each portion governor motion 5 and locking
Nut 14 also checks the displacement of crownblock beam A3.
Other one direction moves with reference to this regulation process, and regulation crownblock beam B9 is by that analogy.
2) vertical and horizontal move simultaneously
With reference to Fig. 2, when needs regulation crownblock beam A3 downwards and moves the most simultaneously, as required downwards and move right
Distance and the pitch of leading screw 15 calculates below crownblock beam A3 respectively and crownblock beam A3 right leading screw 15 needs the circle that rotates
Number.Unclamping the locking nut 14 of two governor motions 5 below crownblock beam A3, rotational lead screw 15, making a support plate 12 move down, until reaching
To value of calculation, unclamp the locking nut 14 of two governor motions 5 in crownblock beam A3 right, rotational lead screw 15 subsequently, make a support plate 12
Move to right, until it reaches value of calculation.Then two governor motions 5 above regulation crownblock beam A3, make a support plate 12 move down, promote sky
Bicycle beam A3 moves down, until a support plate 12 of governor motion 5 below contact crownblock beam A3, then regulates crownblock beam A3 left
Two governor motions 5, make a support plate 12 move to right, and promote crownblock beam A3 to move right, until contact crownblock beam A3 right regulation machine
A support plate 12 of structure 5, finally locks each portion governor motion 5 and locking nut 14 and checks crownblock beam A3 displacement.
Other vertical and horizontal move simultaneously and regulate process with reference to this, and regulation crownblock beam B9 is by that analogy.
