As a kind of improvement of the present utility model, described riser pipe for the first end beating body be provided with for is connected with riser pipe for beating terminal body, described replacing is beaten terminal body and is replaced at riser pipe and beat body shaft length upwards and be at least riser pipe and replace and beat the 1/8 of body axial length.Use technique scheme, it can be by for the setting beating terminal body, make riser pipe replace beat body realize with being fitted and connected of riser pipe while, be effectively improved the structural strength of its connecting portion, so that riser pipe is improved for the stability beaten in the course of the work；Meanwhile, its ilities above-mentioned can be made further to be strengthened for the length setting beating terminal body.
As a kind of improvement of the present utility model, described identical for the diameter beating body with riser pipe for the length of the crossing line segment beating body radial section with riser pipe for beating end face, it is 30 ° for playing end face place plane and riser pipe for beating angle between body axis.Use technique scheme, it can be by arranging for the position and angle of beating end face, make it at riser pipe for throwing in row practical work process, it is further improved for guide effect and the shock resistance effect of seabed mud stone, and then the work efficiency of riser pipe can be promoted further with intensity.
As a kind of improvement of the present utility model, described riser pipe is provided with guiding shoulder for beating body interior, riser pipe is for beating among body, and first end and the riser pipe guided between shoulder are more than the riser pipe between the second end and guiding shoulder for beating body internal diameter for beating body internal diameter；Described riser pipe is gradually reduced on the second end bearing of trend at first end in the internal diameter guiding shoulder correspondence position for beating body.Use technique scheme, it can be by riser pipe for the setting beating body interior structure, when ground and mud are entered wherein, can be risen under the effect guiding shoulder, and by riser pipe for playing the cumulative setting of body internal diameter to avoid ground to block, cause the integral construction efficiency of riser pipe to be affected.
Use the riser pipe for riser pipe auxiliary construction of technique scheme for beating, it can be by being arranged on the riser pipe of riser pipe end for beating, to replace the end of riser pipe directly to form impact in offshore oil drilling platform work progress and between ground, to avoid the damage of riser pipe；Riser pipe then makes ground or mud be able to guiding process for the setting beating end face of replacing beating body, it is avoided to be deposited in riser pipe among beating, meanwhile, use extend obliquely out riser pipe also can be made to replace the shock resistance effect of dozen end to be improved for beating end face.Meanwhile, above-mentioned riser pipe can play good connection effect with other parts for beating when riser pipe is connected, and causes further damage to avoid the inwall of riser pipe to directly receive impact.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram；
Reference numerals list:
1 riser pipe for beat body, 11 first ends, 12 the second ends, 13 for beat end face, 2 replace beat terminal body, 3 guiding shoulders.
Detailed description of the invention
Below in conjunction with detailed description of the invention and accompanying drawing, it is further elucidated with this utility model, it should be understood that following detailed description of the invention is merely to illustrate this utility model rather than limits scope of the present utility model.It should be noted that the word "front", "rear" used in describing below, "left", "right", "up" and "down" refer to the direction in accompanying drawing, word " interior " and " outward " refer respectively to the direction towards or away from particular elements geometric center.
Embodiment 1
A kind of riser pipe for riser pipe auxiliary construction as shown in Figure 1 is for beating, it includes riser pipe for beating body 1, riser pipe is provided with, for beating, the first end 11 being connected on riser pipe on body 1, and extend to the second end 12 outside riser pipe, riser pipe for beat be provided with among the second end 12 of body 1 at least one for beating end face 13, replace and beat end face 13 place plane and riser pipe replaces between the axis beating body 1 angle in the range of 10 to 80 °.
As a kind of improvement of the present utility model, described riser pipe for the first end 11 beating body 1 be provided with for is connected with riser pipe for beating terminal body 2, described for beat terminal body 2 riser pipe replace beat body 1 axial on a length of riser pipe replace and beat the 1/8 of body 1 axial length.Use technique scheme, it can be by for the setting beating terminal body, make riser pipe replace beat body realize with being fitted and connected of riser pipe while, be effectively improved the structural strength of its connecting portion, so that riser pipe is improved for the stability beaten in the course of the work；Meanwhile, its ilities above-mentioned can be made further to be strengthened for the length setting beating terminal body.
