Description
Technical field
The present invention relates to the collection slag technical fields of shaft sinking, particularly relate to a kind of collection slag for open caisson shaft excavation machine
Device and its implementation method.
Background technique
With underground space development build fast development, open caisson using more and more extensive.Open caisson shaft excavation machine
Using improving Construction of Silo efficiency, but due to the particularity of open caisson construction: narrow space, vertical construction, dregs more divide
The problems such as dissipating, the discharge of dregs becomes an important factor in order for hindering construction efficiency in tunneling process.
Currently, thering is mud to slag tap for the method that open caisson is slagged tap, vacuum is slagged tap, manually slag tap, mechanically grab bucket is slagged tap.And
These types mode of slagging tap has limitation, and mud, which is slagged tap, needs to be equipped with mud separation equipment, and well domestic demand fills mud, cost compared with
Height, and it is more demanding to the waterproof sealing of equipment, and overhaul of the equipments difficulty is big；Vacuum, which is slagged tap, to be needed to pre-process dregs, and
And vacuum equipment is expensive；Not only efficiency of manually slagging tap is very low, but also large labor intensity.
The open caisson shaft excavation machine slagged tap of mechanically grabbing bucket includes rock drilling, muck, promotion, discharge refuse, suspention, draining, ventilation
The works such as equipment and sinking headframe and revolution scratch diskette, rock drilling mainly by the cutterhead that is arranged below revolving platform into
Row, muck are carried out by mechanically grab bucket.Using mechanical grab bucket can fast slag tapping, construction efficiency with higher and lower
Cost, but how dregs is gathered into mechanical grab bucket and be convenient for the position of crawl but very difficult.
Summary of the invention
For the deficiency in above-mentioned background technique, the present invention propose a kind of collection slag device for open caisson shaft excavation machine and
Its implementation method, the mechanical grab bucket mode of slagging tap for solving existing open caisson shaft excavation machine are difficult to gather dregs convenient for grabbing
The problem of position taken.
The technical scheme of the present invention is realized as follows: a kind of collection slag device for open caisson shaft excavation machine, including even
Connect the outer sliding case below the revolving platform of open caisson shaft excavation machine.Under the drive of revolving platform, outer sliding case can do circumference
Movement；Under the drive of the radial oil cylinders of open caisson shaft excavation machine, outer sliding case can be close and far from vertical shaft center.In outer sliding case
Sliding is provided with interior sliding case, and the drive cylinder that sliding case is flexible in driving, drive cylinder energy are provided between interior sliding case and outer sliding case
It is enough to drive interior sliding case along outer sliding case stretching motion.The bottom end rotation of interior sliding case is provided with slag trap, and slag trap can be with outer
Sliding case carries out circular motion and radial motion, while sliding case can also rotate in.The bottom end of interior sliding case is arranged at intervals with two
A stop block, the top of slag trap are provided with the limited block being located between two upper stop blocks, guarantee that slag trap is only opposite
Interior sliding case rotates in specific angular range, guarantees no matter revolving platform rotates forward, or reversion, can make slag trap in week
Gather dregs to vertical shaft center to when rotating and moving radially.
The bottom end of the interior sliding case is provided with fixing axle, and the slag trap is rotatably arranged in fixing axle, provides one kind
Fixing axle is relatively fixed with interior sliding case and slag trap is relative to the collection slag mode of fixed axis rotation.
Or the bottom end of the interior sliding case is provided with rotation axis, the slag trap fixed setting on the rotating shaft, provides
A kind of rotation axis sliding case rotation and rotation axis and the relatively-stationary collection slag mode of slag trap in.
Further, the cross section of the slag trap is drops, and slag trap includes two symmetrical arc side plates,
Arc side plate can guarantee that when gathering dregs, dregs can be moved along radian direction to vertical shaft center.The upper end of arc side plate
Mouth and lower port are provided with sealing plate, and the stub end of sealing plate and interior sliding case are rotatablely connected, and sealing plate can prevent dregs from entering two
Gap between arc side plate.
Further, it is provided with plate below the sealing plate at the lower port, can guarantees to carry out dregs sufficiently poly-
Hold together.
