Side）Right-hand member end with middle part sealing platform 5 is hinged, and its pin joint be the first pin joint 8, by the be hinged of limited location,
The direction that middle part sealing platform 5 can be allowed to be heaved relative to sealing beam 4 rotates around the first pin joint 8.
The left end end of middle part sealing platform 5 is hinged with the right-hand member of end seals platform 6, and its pin joint is the second pin joint 7,
The right-hand member of end seals platform 6 is provided with chute 11, and its second pin joint 7 is slidably matched with the chute 11, the pin of the second pin joint 7
Axle is slided in the chute 11 and used, and the first half sealing flatcars 2 and the second half sealings are flat when the length of chute 11 meets to remove drilling rod
The needs of the folding by a small margin of car 3.End seals platform 6 is supported in above the crossbeam on chassis 1, the left end of end seals platform 6 with
The crossbeam on chassis 1 is hinged, and so, end seals platform 6 also can keep level under cantilever situation；Its position of the second pin joint 7
Higher than the position of the first pin joint 8；The top of the middle part sealing platform 5 and the top of end seals platform 6 are provided with turnover panel 10, turn over
The left end of plate 10 is be hinged with end seals platform 6, and right-hand member and the middle part sealing platform 5 of turnover panel 10 overlap, the upper surface of turnover panel 10
Higher than the upper surface of sealing beam 4, a upper surface high turnover panel 10 of the upper surface of turnover panel 10 than sealing beam 4 is thick under normal circumstances
Degree.
Sealing beam 4 between the center one end of chassis 1 and the quadra on chassis 1 away from being connected with horizontally disposed hydraulic jack
9, the stroke of the hydraulic jack 9 is usually 2.5m, can ensure that rig exchanges drilling rod for and removes the needs of drill bit.
As shown in Figure 1 and Figure 2, the second half sealing flatcar 3 is identical with the first half sealing structures of flatcar 2, and the second half envelopes
Mouthful flatcar 3 and the first half sealing flatcars 2 are symmetrical arranged on center chassis 1, therefore are just no longer described in detail herein.
The quadra on the chassis 1 is provided with the slideway 12 for the sealing open and close movement of beam 4, seals the front and rear sides of beam 4
It is equipped with pulley 13 matching used with slideway 12.
Elastic support 16 is provided between the downside of the middle part sealing platform 5 and the outside for sealing beam 4.Its elasticity branch
The effect of support body 16 is the most of gravity for supporting middle part sealing platform 5 and end seals platform 6, can so greatly reduce
Hydraulic jack 9 when the sealing flatcar 2 of driving the first half and the second half sealing flatcars 3 do significantly opening and closing motion it is required most
Big pulling force, and improve the first half sealing flatcars 2 simultaneously and when the second half sealing flatcars 3 make significantly opening and closing motion, seal beam 4
Front and rear sides pulley 13 and the contact situation between slideway 12.
The elastic support 16 includes connecting rod 17, elastomer 18, sleeve 19, and the connecting rod 17 is away from center chassis
One end and the downside of middle part sealing platform 5 are hinged, and connecting rod 17 is close to center chassis one end and sleeve 19 away from center chassis one
End is used cooperatively, and sleeve 19 is be hinged close to center chassis one end and sealing beam 4, and the sleeve 19 is away from center chassis one end end
Circumferentially arranged with first baffle 20, the middle part of connecting rod 17 is provided with second baffle 21, between first baffle 20 and second baffle 21
Provided with elastomer 18.
The elastomer 18 is compression spring, and compression spring is sheathed on connecting rod 17, and the both ends of compression spring respectively with
First baffle 20 is fixedly connected with second baffle 21.
The elastomer 18 is rubber axle sleeve, and rubber axle sleeve is sheathed on connecting rod 17, and the both ends of rubber axle sleeve respectively with
First baffle 20 is fixedly connected with second baffle 21.
The elastomer 18 is metal clips, and metal clips is uniformly arranged along the circumference of connecting rod, and the two of metal clips
End is fixedly connected with first baffle 20 and second baffle 21 respectively.
As shown in Figure 3, Figure 4, when removing drilling rod, the first half sealing flatcars 2 and the second half under the driving of hydraulic jack 9
Sealing flatcar 3 does open and close movement by a small margin, now the space space between middle part sealing platform 5 and end seals platform 6 by
Turnover panel 10 covers.
As shown in Figure 5, Figure 6, when removing drill bit, the first half sealing flatcars 2 and the second half under the driving of hydraulic jack 9
Sealing flatcar 3 does significantly open and close movement, and the distance that the second pin joint 7 slides in chute 11 exceedes the length of chute 11,
Because the quadra of the end and chassis 1 of end seals platform 6 is hinged, constrained by this, middle part sealing platform 5 and end seals
It is be hinged as being hinged between two compression members between platform 6, because the position of the second pin joint 7 is higher than the first pin joint 8
Position, difference in height is formed, under the promotion of hydraulic jack 9, produce a torque and platform 5 and end seals are sealed into middle part simultaneously
Platform 6 arches upward and then folded, to adapt to the first half sealing flatcars 2 and the space needs of the second half continuous openings for sealing flatcar 3.
Under normal circumstances, the first half sealing flatcars 2 and the second half sealing flatcars 3 are in opening and closing movement by a small margin, and second
Some position that pin joint 7 is always in chute 11, now end seals platform 6 in the horizontal plane seal by transfixion, only middle part
Mouth platform 5 seals the horizontal movement of platform 6 with the sealing opposed end of beam 4, although middle part sealing platform 5 and end seals platform 6
Between have relative motion in horizontal plane, but the turnover panel 10 on chute 11 can ensure the closure in whole operation space,
The upper surface of turnover panel 10, which is only higher by, seals beam 4 upper surface one thickness of slab, about 1 centimetre~2 centimetres.
To sum up, the closing device designed by the program can close the chassis 1 of rig, rig all the time in the rig course of work
Chassis 1 top that steel casts pit shaft 14 is fixed on by ring flange 15, and the needs of the various apertures of closing device can be met, and the
The various motions that half seals in flatcar 2 and the second half sealing flatcars 3 between each part are realized by the reciprocating motion of hydraulic jack 9
's.Engineering driller Totally enclosed follow-up closing device is set up, and the safety of operating personnel and facility on closing device has been effectively ensured,
Also achieve working space maximum on engineering driller chassis 1 simultaneously.
