As shown in fig. 1, the embodiment of the present invention proposes a pipe rapping device, which is used for rapping the outer wall of a pipe 400 and comprises a supporting assembly 100, a power assembly 200 and an executing assembly 300.

The supporting component 100 is sleeved on the pipeline 400, the executing component 300 is connected to the supporting component 100, the supporting component 100 is used for supporting the executing component 300 to execute the motion of rapping the outer wall on the outer surface of the pipeline 400, and the power component 200 is connected with the executing component 300 and used for driving the executing component 300 to move.

In one embodiment of the present application, as shown in fig. 3, the actuator assembly 300 includes an inner ratchet 310, a main shaft 320, a ratchet arm 330, a hammer 340 and an elastic member 350.

The inner ratchet 310 has a structure with ratchet teeth on the inner surface, for the convenience of the following description, the axis of the inner ratchet 310 is used as the axis, the position with the largest diameter among the ratchet teeth is called the bottom of the ratchet teeth, the position with the smallest diameter among the ratchet teeth is called the top of the ratchet teeth, and the inner ratchet 310 and the pipe 400 are coaxially arranged, rotate around the pipe 400, and the inner ratchet 310 is driven to rotate by the power assembly 200.

The main shaft 320 is a linear shaft body, is disposed parallel to the pipe 400, and is connected to the support assembly 100 in a self-transmitting manner.

The ratchet arm 330 is a structure connecting the main shaft 320 and the ratchet, one end of the ratchet arm 330 abuts against the inner wall of the inner ratchet 310, the other end of the ratchet arm 330 is fixedly connected with the main shaft 320, when the inner ratchet 310 rotates, one end of the ratchet arm 330 is driven to move on the inner wall of the inner ratchet 310, and along with the movement of one end of the ratchet arm 330, the main shaft 320 fixedly connected with the other end rotates.

The hammer 340 has a structure including a hammer arm and a hammer head, one end of the hammer 340 is fixedly connected to the spindle 320, and when the spindle 320 rotates, the hammer 340 also rotates around the axis of the spindle 320.

The elastic member 350 is an annular elastic member 350, and is sleeved on the main shaft 320, and one end of the elastic member is fixedly connected to the hammer 340, and the other end of the elastic member is connected to the supporting assembly 100, because the supporting assembly 100 is a fixed structure, and the main shaft 320 drives the hammer 340 to rotate, the elastic member generates elastic potential energy along with the rotation of the hammer 340.

Preferably, the combination of the main shaft 320, the ratchet arm 330, the hammer 340 and the elastic member 350 is provided in plural sets, which are circumferentially arranged around the inside of the inner ratchet 310. The rapping effect is improved, and the circumference of the pipeline 400 receives the same rapping force, so that the inner blockage can fall off uniformly.
