Description
Technical field
The present invention relates to piling Technology fields, and in particular to a kind of low clearance multi-section type drilling rod splicing centering body.
Background technique
In existing pile foundation construction boring procedure, often have under high-voltage line, communication line is off the net or bridge below construct
Operating condition, since construction height is limited, and the length of drilling rod is very long, when drilling straight down, drilling rod and its auxiliary device need compared with
High construction space can only wait the power grid of upper space, communication network lines temporarily disconnected after drilling constructions again by it
It connects, needs to coordinate with negotiations such as power grid departments so for a long time, often schedule delays, what can not be coordinated really can only repair
Change detail design, causes the significant wastage of time, economy and cost of labor etc..
A kind of existing solution is that drilling rod is divided into multi-section type, with going deep into for drilling, splices each drilling rod section one by one.But
Since low clearance multi-section type drilling rod belongs to emerging construction means, matched splicing centralising device there is no, at present only using lifting
Equipment slings drilling rod section to be spliced, is then spliced drilling rod section centering by manually commander and control, such operation is very
Trouble, low efficiency, once and suspension hook fall off, will cause serious accident.
Summary of the invention
The present invention is to solve the drilling rod section in pile foundation construction splices the technical problem that centering is difficult, risk is high.
In order to solve the above technical problems, the present invention provides a kind of low clearance multi-section type drilling rods to splice centering body, including
Rack, cursor and rotation wrist, the cursor, which horizontally rotates, to be connected in the rack, and the rotation wrist horizontally rotates connection
On the cursor, the rotation wrist is equipped with clamping part, and the clamping part for clamping drilling rod section to be spliced vertically.
Optionally, the cursor is connect by hydraulic telescopic machanism with the rack.
Optionally, the cursor is plate, and the cursor is equipped with hollow out.
Optionally, being additionally provided in the rack can be along the drilling rod fixture that the stands longitudinal moves.
Optionally, the cursor is right angled triangle, and the bevel edge of the cursor is corresponding with the top of the rack to be set
It sets.
A kind of low clearance multi-section type drilling rod provided by the invention splices centering body, including cursor and rotation wrist, rotation
Arm is rotatablely connected on the rack, and rotation wrist is rotatably connected on cursor, and rotation wrist can grasp drilling rod section vertically；Pass through cursor
It is rotatably assorted with the two-stage of rotation wrist, can easily realize the accurate centering of bar section, safe operation, conveniently.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of low clearance multi-section type drilling rod splicing centering body provided in an embodiment of the present invention.
Appended drawing reference:
1, pivot holder；2, cursor；3, hollow out；4, rack；5, fixture；6, clamping part；7, wrist is rotated.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of low clearance multi-section type drilling rod provided in an embodiment of the present invention splices centering body, including rack
4, cursor 2 and rotation wrist 7, rack 4 is vertical when in use to place, and the front side of rack 4 is the position for splicing drilling rod section, therewith phase
Adjacent side is equipped with two pivot holders 1 of longitudinal gap arrangement, and cursor 2 is rotatably connected between two pivot holders 1, from
And horizontally rotates and be connected in rack 4；Rotation wrist 7 is rotatably connected on cursor 2, and can be horizontally rotated relative to cursor 2,
It rotates wrist 7 and is equipped with clamping part 6, clamping part 6 for clamping drilling rod section to be spliced vertically.
When splicing drilling rod section, pass through loop wheel machine first for drilling rod section handling to be spliced to the side of rack 4, cursor 2
Swing make rotate wrist 7 close to drilling rod section to be spliced, then by rotation wrist 7 fine tuning, make rotate wrist 7 clamping part 6 be clipped in
Splice on drilling rod section；Then cursor 2 is rotated to position side to be spliced, make the axle center of drilling rod section to be spliced close to lower section both
Splice drilling rod section, then by the fine tuning to rotation wrist 7, make drilling rod section to be spliced and both to splice drilling rod section concentric, in case splicing
Operation.
From the foregoing, it will be observed that the disclosure is rotatably assorted by the two-stage of cursor 2 and rotation wrist 7, it can be achieved that joint to be spliced exists
Multiple degrees of freedom on horizontal plane is adjusted, and thus can easily realize the accurate centering of bar section, easy to operate, high-efficient；And due to boring
It is all to be driven by cursor 2 and rotation wrist 7, therefore safety is guaranteed that the horizontal position of bar section, which is adjusted,.
In some embodiments, cursor 2 is connect by hydraulic telescopic machanism with rack 4, since cursor 2 needs to rotate
Biggish angle, thus by hydraulic-driven it is more convenient, laborsaving, rotate wrist 7 the amplitude of accommodation it is smaller, can by manually come
Control, operation is also more flexible when finely tuning centering.
In some embodiments, cursor 2 is plate, since the power that cursor 2 is vertically arranged, and is subject to is also longitudinal
, therefore, the cursor 2 of plate is light, and meets mechanical requirements, moreover, hollow out 3 can also be set on cursor 2, the hollow out
3 can be circular hole, so as to further mitigate the weight of cursor 2, but will not influence its intensity.
In some embodiments, it is additionally provided with the drilling rod fixture 5 that can be vertically moved along rack 4 in rack 4, is set in rack 4
There is the track longitudinally extended, fixture 5 feeds down drilling along track longitudinal sliding motion, for clamping after the splicing of drilling rod section.
In some embodiments, cursor 2 is right angled triangle, and the bevel edge of cursor 2 is corresponding with the top of rack 4 to be set
It sets, 2 structure of cursor of triangle is more stable, and the location of bevel edge is equivalent to the part of the missing of cursor 2, is splicing
When centering, fixture 5 is located at the lack part, to not only improve 2 intensity of cursor, but also keeps the structure of mechanism more compact.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features；
And these are modified or replaceed, technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution spirit and
Range.
