(V) detailed description of the preferred embodiments
In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be further described with reference to the accompanying drawings.
Example 1
As shown in fig. 1-2, the utility model relates to a laying pipe inner wall cleaning device, including rotary power device 1, rotary power device 1 is the electric hammer in this embodiment, and the electric hammer can enough export the rotation, can export axial direction's impact simultaneously, and is better to the effect of polishing of stubborn cinder. The rotary power device 1 is connected with the connector 2, the connector 2 is a bendable slender structure body, the length of the connector 2 is not less than that of the spinning pipe, the connector 2 is made of steel wire ropes, has certain rigidity and can be bent, and the rotary power device is suitable for being deeply penetrated into the bent spinning pipe to polish oxide scales on the inner wall of the spinning pipe.
One end of the connecting body 2, which is far away from the rotary power device 1, is connected with an inner grinding head 3, the electric hammer outputs rotation and axial impact, the rotation and the axial impact are transmitted to the inner grinding head 3 through a steel wire rope, and the inner grinding head 3 jumps and rotates in the spinning pipe to grind away oxide skin on the inner wall of the spinning pipe. Meanwhile, the steel wire rope also rotates and jumps under the power of the electric hammer, and a certain auxiliary polishing effect can be achieved.
The rotary power device 1 is connected with the connector 2 through the first connecting head 4, and the problem that when the electric hammer directly clamps the steel wire rope, the steel wire rope is easy to deform under clamping force to cause loosening and hurt people in the working process is avoided.
