Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to Fig.1, it is a kind of underwater bottom expanding drill of rotary digging disclosed by the utility model, including is wholely set 1 He of link block
Armlet waistband 2, link block 1 and armlet waistband 2 are cylindrical body.The upper surface of link block 1 offers link slot 14, link block 1
Lower end surface and armlet waistband 2 it is fixed.Armlet waistband 2 is fixed with more between the side of link block 1 and the side wall of link block 1
A floor 15, floor 15 are preferably three and are arranged by center of circle rotational symmetry of the axis of link block 1.
Referring to Fig.1 when base expanding and base expanding, link block 1 is mounted on drilling machine by link slot 14, drilling machine drives link block 1 and armlet
Waistband 2 is rotated, while applying pressure to armlet waistband 2, declines armlet waistband 2 and link block 1 together.Floor 15 then increases
Add the structural stability between armlet waistband 2 and link block 1, improves the stress intensity of armlet waistband 2.
Referring to Figures 1 and 2, side of the armlet waistband 2 far from link block 1 is coaxially fixed with lifting ring 3, in lifting ring 3 in
One end far from armlet waistband 2 is fixed with lifting bearing 10, and limited post 7, lifting ring 3, limited post are equipped in lifting bearing 10
7, lifting bearing 10 is coaxial arrangement.The side of limited post 7 is also arranged restraining position ring block 16, and stop collar 16 is located at lifting ring 3
Lower section will lead to drilling machine by armlet waist after touching the upper surface of stop collar 16 when armlet waistband 2 drives lifting ring 3 to decline
Mutation pressure with 2 feedbacks, prompts the decline of worker's armlet waistband 2 to arrive extreme position.
Referring to Fig. 2, it is fixed with heave sensor 5 in lifting bearing 10,10 edge of lifting bearing is recorded by heave sensor 5
Limited post 7 decline stroke distances.Before base expanding and base expanding, worker simulates base expanding and base expanding in earth's surface in advance, records the stroke distances of lifting ring 3
Relationship between bellout diameter.In base expanding and base expanding construction, the stroke distances recorded by heave sensor 5 are precisely intuitively fed back
The diameter of base expanding and base expanding, when bellout diameter meets the requirement of setting, worker can stop operation drilling machine immediately, to ensure bellout diameter
Precision.
Referring to Fig. 2, the side of stop collar 16 is fixed with dynamic bearing in one end far from lifting ring 3, and the side of dynamic bearing is solid
Surely there is disk 4, dynamic disk 4 is parallel to the setting of armlet waistband 2 and is provided with base expanding and base expanding component between armlet waistband 2.Base expanding and base expanding group
Part includes being hingedly connected to armlet waistband 2 close to multiple drilling rods 11 of dynamic 4 side of disk, preferably two, drilling rod 11 and about shield
The axisymmetrical of arm waistband 2 is arranged, and the material of drilling rod 11 and dynamic disk 4 is steel, can effectively improve drilling rod 11 and dynamic disk 4
Stress intensity.Dynamic disk 4 is hingedly connected with the rotational pin 12 being correspondingly arranged with two drilling rods 11 close to one end of armlet waistband 2,
Rotational pin 12 one end and drilling rod 11 far from dynamic disk 4 are articulated and connected far from one end of armlet waistband 2.
Referring to Fig. 2, the length direction of a lateral edge drilling rod 11 of the drilling rod 11 far from lifting ring 3 is fixed with multiple alloys and bores tooth
13, it is equal that any two adjacent alloy bores the distance between tooth 13.When armlet waistband 2 declines, the distance between dynamic disk 4 subtracts
It is small, so that the hinged place of drilling rod 11 and rotational pin 12 is moved to the direction far from lifting ring 3, realize the expansion of drilling rod 11.
Drilling machine drives armlet waistband 2 to rotate simultaneously, and the drilling rod 11 after making expansion carries out base expanding and base expanding construction.
Referring to Figures 1 and 2, it moves on disk 4 and is fixed with rotation sensor 6.Dynamic disk 4 is recorded by rotation sensor 6
Velocity of rotation, underworker judge whether base expanding and base expanding is abundant.The multiple alloys being placed equidistant with bore tooth 13 and make the stress of drilling rod 11 more
Add uniformly, when base expanding and base expanding in ground everywhere in by digging uniformly, to improve the quality of construction.
Referring to Figures 1 and 2, the one end of limited post 7 far from armlet waistband 2 is coaxially fixed with quiet disk 8, and quiet disk 8 is located at
The lower section of dynamic disk 4, the material of quiet disk 8 are identical as dynamic disk 4.Alignment sensor 9, orientation sensing are fixed on quiet disk 8
Device 9 is used to detect the rotation data of quiet disk 8.During base expanding and base expanding, moving disk 4 and rotate, quiet disk 8 should be connected to ground end always,
The data of alignment sensor 9 are 0, when the data of alignment sensor 9 are not 0, illustrate that quiet disk 8 is carried out with servo-actuated disk 4
Certain rotation, base expanding and base expanding are insufficient.Worker can judge the quality of base expanding and base expanding by the data of alignment sensor 9, convenient for taking in time
Measure reduces the processing in later period, is conducive to the progress for accelerating construction, reduces the cost of construction.
It the implementation principle of the present embodiment and has the beneficial effect that
Before base expanding and base expanding, worker simulates base expanding and base expanding operation, the stroke distances and base expanding and base expanding that record lifting ring 3 declines in earth's surface in advance
Relationship between diameter.When formal base expanding and base expanding, drilling machine drives bottom expanding drill decline, enters underground, quiet disk 8 is made to be connected to ground
Bottom.Drilling machine drives armlet waistband 2 to rotate, while applying pressure to armlet waistband 2, and armlet waistband 2 drives lifting ring 3 close to quiet circle
Disk 8 extends out drilling rod 11, carries out base expanding and base expanding.When the bellout diameter of the corresponding setting of the data that heave sensor 5 detects, worker
It can stop operation drilling machine immediately.
The stroke distances of lifting ring 3 are converted into intuitive bellout diameter by heave sensor 5 and fed back by the utility model
The precision of base expanding and base expanding is improved convenient for the operation of worker's control drilling machine to worker, it is auxiliary by dynamic disk 4 and the rotation data of quiet disk 8
Assistant engineer people judges base expanding and base expanding degree, convenient for taking timely measure, reduces the cost of later maintenance processing.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
