Abstract
The utility model relates to a kind of slurry pump of drilling machine snubber.On base, seal the end opening of fixed cylinder, the sealing securing cover plate suitable for reading of cylindrical shell, cylindrical shell has closed cavity, on the face of cylinder of cylindrical shell, has into and out of interface, communicates with closed cavity into and out of interface.It is simple in structure, can eliminate vibrations and the friction of mud channel.
Description
Technical field
The utility model relates to a kind of snubber, is particularly suitable for rig and uses.
Background technology
In pit shaft freezing drilling construction, produce friction because slush pump flow pulse change amplitude causes greatly the serious vibrations of mud channel and ground, equipment, and cause at the bottom of drilling process mesopore not steadily to pressing, making to hole easily produces deflection.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of slurry pump of drilling machine snubber, and it is simple in structure, can eliminate vibrations and the friction of mud channel.
The technical scheme in the invention for solving the technical problem is: the end opening that seals fixed cylinder on base, the sealing securing cover plate suitable for reading of cylindrical shell, cylindrical shell has closed cavity, on the face of cylinder of cylindrical shell, has into and out of interface, communicates with closed cavity into and out of interface.
The utility model can be eliminated vibrations and the friction of mud channel, greatly extends the application life of mud channel high-voltage tube, eliminates because mud channel shakes the potential safety hazard of bringing, and improves drilling construction quality, has good promotion prospect in drilling construction industry.
Brief description of the drawings
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model top view.
Detailed description of the invention
As shown in Figure 1, 2, the end opening of seal welding cylindrical shell 4 on base 7, the seal welding cover plate 2 suitable for reading of cylindrical shell 4, cylindrical shell 4 has closed cavity 3, has into and out of interface 5,8 on the face of cylinder of cylindrical shell 4, communicates with closed cavity 3 into and out of interface 5,8.
Between described cylindrical shell 4 and cover plate 2, be welded and fixed stiffener 1, increase the fastness between cylindrical shell 4 and cover plate 2.
Between described cylindrical shell 4 and base 7, be welded and fixed reinforcing rib 6.
Utilize air pressurized volume-diminished, decompression volume expansion principle, serial buffer in mud channel, utilizes air as cushion, not steady to pressing at the bottom of mud channel vibrations, friction phenomenon and hole that alleviation slush pump flow pulse change amplitude causes greatly.
