Description

Inner wall cleaning device for laying pipe

(I) technical field

The utility model belongs to the technical field of cold rolling ribbed steel bar production facility, specifically be a laying pipe inner wall cleaning device.

(II) background of the invention

When the laying head works, the wire rod is fed into the hollow shaft of the laying head through the inlet conduit of the laying head, and the hollow shaft drives the laying head pipe and the laying head disk to rotate together, so that the wire rod entering the hollow shaft passes through the laying head pipe rotating at a high speed and is laid out of the coil along the circumferential tangential direction of the outlet of the laying head pipe.

When the wire rod passes through the wire-feeding pipe at high speed, oxide scales generated by the friction of the steel bars are accumulated at the corners of the wire-feeding pipe and are adhered to the inner wall of the wire-feeding pipe under a high-temperature environment (about 600 ℃) to form 'iron lumps' which are difficult to clean. When the spinning machine is started again for production, the resistance of the steel bars in the spinning pipe is too large, so that the steel is piled and the spinning machine cannot be started normally. The laying pipe can only be stopped and replaced by a new laying pipe, so that the effective operation rate of the equipment is low, the service life of the laying pipe is short, and the cost of spare parts is high or low.

(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.
