Description
Technical field
The utility model relates to drilling construction field, especially a kind of Telescopic drill rod set applied in MJS construction
Pipe.
Background technique
Since high mud jacking air water is to the strong disturbance of layer of sand when MJS constructs, need to be embedded to drilling rod or casing.Common casing
Not rotating can not move up and down, when the projected depth on basis is deeper, need to spend a large amount of manpower and when indirectly, tear set open
Pipe.
Common inserting or withdrawing sleeves method is as follows, 1, drilling rod all extractions, host displacement, and casing disposably dismantles 10m, host
In place, setting of casing again.This method is time-consuming and laborious.2, drilling rod, position of host machine are constant, dismantle a section every time using opposite opened casing
80cm.Split sleeve in this method from it is great, be not easy to dismantle, the labor intensive and operation carries out in mud, building ring
Border is poor.
Summary of the invention
The purpose of this utility model is provided a kind of applied in MJS construction according to above-mentioned the deficiencies in the prior art
Telescopic drill rod casing, without dismantling casing after the completion of drilling, saves manpower by sleeve design at telescopic.
The utility model aim realization is completed by following technical scheme:
A kind of Telescopic drill rod casing applied in MJS construction, described sleeve pipe is gone along with sb. to guard him in the drilling-rod external wall, special
Sign is: described sleeve pipe includes that the area of section being arranged from top to bottom is gradually reduced and is able to satisfy several sections shield being socketed one by one
Tin, it is equipped with the component for preventing the adjacent casing from completely disengaging between the adjacent casing, is equipped between the adjacent casing
The convex block that casing described in upper layer can be driven to move, several section casings constitute telescopic connection by retractable driving device.
The retractable driving device is fixed on the top of described sleeve pipe, the retractable driving device include flexible cable, pulley and
Hoist engine, one end of the flexible cable are fixed on the bottom of described sleeve pipe, and the other end is wrapped in the hoist engine by the pulley
On.
The component includes step and bayonet, and the casing bottom on upper layer, the bayonet setting is arranged in the step
At the top of the casing of lower layer.
The utility model has the advantages that: structure is simple, and construction can be completed without dismantling casing, save human and material resources, and bores
Bar long service life, construction speed are fast.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the connection schematic diagram of extension type sleeve and connector in the utility model.
Specific embodiment
The utility model feature and other correlated characteristics are described in further detail by embodiment below in conjunction with attached drawing,
In order to the understanding of technical staff of the same trade:
As shown in Figure 1-3, marking 1-13 to respectively indicate in figure are as follows: top casing 1, intermediate casing 2, end casing 3, bayonet
4, bayonet 5, tongue and groove 6, wirerope 7, retractable driving device 8, connector 9, steel wire rope fixing part 10, pulley 11, hoist engine 12, enterprise
Mouth 13.
Embodiment: the utility model relates to a kind of Telescopic drill rod casings applied in MJS construction.
As shown in Figure 1, this structure includes the retractable driving device 8 being from top to bottom arranged, and connector 9, extension type casing,
Wherein retractable driving device 8 includes the wirerope 7, hoist engine 12 and pulley 11 as flexible cable.
As shown in Figure 1, 2, extension type casing is gone along with sb. to guard him in drilling rod (not shown) outer wall, for protecting drilling rod, is improved
Drilling life of drill pipe.Extension type casing from top to bottom includes top casing 1, intermediate casing 2, end casing 3, top casing 1
Diameter be slightly larger than the diameter of intermediate casing 2, the diameter of intermediate casing 2 is slightly larger than the diameter of end casing 3, under external force
End casing 3 can be taken in intermediate casing 2, in the casing 1 of the intermediate income of casing 2 top.
The top of intermediate casing 2 is symmetrically arranged with bayonet 4, and the bottom end of top casing 1 is provided with compatible with bayonet 4
Rank, when construction, are affected by gravity, and intermediate casing 2 can be dropped out from top casing 1, when bayonet 4 is snapped down to step, are supported by step
Firmly, intermediate casing 2 is prevented to be kept completely separate with top casing.The top of end casing 3 is symmetrically arranged with bayonet 5, the bottom of intermediate casing 2
End is equipped with step compatible with bayonet 5, and when construction is affected by gravity, and end casing 3 can be dropped out from intermediate casing 2, bayonet 5
It when being snapped down to step, is resisted by step, end casing 3 is prevented to be kept completely separate with intermediate casing 2.
As shown in Figure 2,3, the bottom of retractable driving device 8 is connected by connector 9 with the top of top casing 1, is used to
The position of fixed extension type casing.Top casing 1, intermediate casing 2, end casing 3 are attached by wirerope 7, steel wire
One end of rope 7 is fixed on the bottom surface of end casing 3 by steel wire rope fixing part 10, and the other end is wrapped in hoist engine by pulley 11
On 12, hoist engine 12 starts, reel winding wire ropes 7, and wirerope 7 drives end casing 3 to move up.
In end, the bottom of casing 3 is equipped with the tongue and groove 13 as convex block, when retractable driving device 8 works, end casing 3
It is incorporated into intermediate casing 2, when tongue and groove 13 resists the barrel of intermediate casing 2, intermediate casing 2 is driven to move upwards.In centre
The bottom of casing 2 is equipped with the tongue and groove 6 as convex block, and when retractable driving device 8 works, intermediate casing 2 is incorporated into top casing 1
Interior, when tongue and groove 6 resists the barrel of top casing 1, casing completes contraction task.Without dismantling extension type set after the completion of drilling
Pipe, saves human and material resources.
The present embodiment is in the specific implementation: the cross sectional shape of connector 9 is rounded, and area of section is cut than top casing 1
Face area is big, material saving under the premise of meeting fixed extension type sleeve position.
The quantity of wirerope 7 is two, and the quantity of pulley 11 is two, is lifted by crane more labor-saving when extension type casing.
Although above embodiments are elaborated referring to conception and embodiment of the attached drawing to the utility model aim,
But those skilled in the art will realize that still may be used in the case where no disengaging claim limits the precondition of range
To make various modifications and variations to the utility model, therefore will not repeat them here.
