Will be. Thereafter, as the position adjusting means 300 is driven, the position of the crushing means 200 is changed.

On the other hand, the shredding means 200 associated with the position adjusting means 300 may be operated in plurality. When moving the actual pipe, storage tank, etc., obstacles on the driving direction side of the traveling mechanism may exist in various positions in the vertical direction or the left and right. In this case, it is not only cumbersome to remove it with one of the shredding means 200, but also in terms of working time.

In this case, when the crushing means 200 is provided in plural, the obstacle removal operation such as sludge may be performed more easily. Referring to FIG. 4, in order to remove obstacles existing in the left and right driving directions of the traveling mechanism. By rotating the guide rail 311 to move the moving frame 315 to the left and right of the driving direction, it can be seen that the plurality of shredding means 200 to move to a position to remove it.

And, referring to Figure 5, in order to remove the obstacles existing in the driving direction side of the traveling mechanism by operating the third drive member 323 to raise the connection arm 321 to the plurality of crushing means ( It can be seen that 200 is moved to the position where each obstacle exists. As described above, since the plurality of shredding means 200 is provided, the above operation is efficiently performed.

In addition, referring to Figure 6, when the crushing means 200 is provided with a plurality of obstacles when the removal of the obstacle is not easy to see that the driving mechanism is combined to facilitate the running on the obstacle to the shape of a wheel close to the circular shape Can be. When combined in the shape of the wheel as described above to ride on the obstacle in the direction of travel of the driving mechanism serves to allow the driving mechanism to run in the future (see Figure 8).

In the above, the configuration of the present invention has been described, and in the following, an operation process of the present invention mounted and operated on the driving mechanism will be described.

Figure 7 is a state diagram showing a state in which the driving mechanism is equipped with the present invention to remove the obstacle, Figure 8 is a state diagram showing the state in which the driving mechanism is equipped with the present invention assists the obstacle driving, Figure 9 is the present invention It is a state diagram showing the driving mechanism mounted to drive the vertical tube.

First, referring to FIG. 7, the traveling mechanism is introduced to inspect the inside of a structure such as a pipe, and foreign matter such as sludge that interferes with running is accumulated at the front end of the traveling mechanism to form an obstacle.

The operator recognizes this situation through an image device (not shown) provided in the driving mechanism and signals a control unit to move the plurality of shredding means 200 up and down. According to the signal according to the embodiment of the present invention while the hydraulic pressure is supplied to the hydraulic cylinder implemented by the third drive member 323 any one of the plurality of shredding means 200 moves to the top, the other one hydraulic cylinder The oil pressure will be released to the lower portion.

Now, when the shredding means 200 is moved to a position suitable for removing obstacles such as sludge, the operator gives a signal through the controller again to operate the shredding means 200. In the embodiment of the present invention according to the signal, the motor implemented by the first driving member 230 is rotated, the support frame 210 that was connected to the motor shaft is rotated together with the plurality of blades 221 Will collide with the obstacle. The obstacle starts to be crushed gradually as it collides with the plurality of blades 221 and no longer disturbs the running of the driving mechanism.

Next, FIG. 8 illustrates an obstacle in which foreign substances such as sludge and chemicals are firmly hardened and not crushed by the crushing means 200. This will be a later action after the worker attempts to remove the obstacle through the above process, but the result is not smooth.

If the worker is not crushed even though the above process proceeds, the operator may choose a method that can proceed smoothly beyond the obstacle. First, a signal is supplied to a controller and the hydraulic cylinder is driven to control the hydraulic pressure supply of the hydraulic cylinder so that the plurality of crushing means 200 can move to the same position.

When the plurality of shredding means 200 moves to the same position, the operator sends a signal to the controller again to drive the first driving member 230 to support the support frame 210 of the plurality of shredding means 200. Position the cross structure to intersect.

In the exemplary embodiment of the present invention, when two crushing means 200 are operated and two crushing means 200 are crossed and combined, the shape of the circular wheel becomes close. Now the signal to the control unit again to rotate the two motors implemented by the first driving member 230 at the same speed at the same time. That is, the two crushing means 200 serve as driving assistance wheels at the front end of the traveling mechanism.

Now, when the hydraulic cylinder is slowly raised while rotating the two crushing means 200 to cross the obstacle, the driving assistance wheels implemented by the two crushing means 200 are gradually climbed on the obstacle.

Then, when the hydraulic cylinder is operated again, the front end of the traveling mechanism is heard by the traveling auxiliary wheels having the upper end of the obstacle as a supporting point. At this time, since the driving assistance wheels continue to rotate, the driving mechanism may overcome obstacles.

Next, in Figure 9, the driving mechanism can be seen when driving the vertical tube made of a material that reacts to the magnetic, first, the worker is supplied with hydraulic pressure to the hydraulic cylinder through the control unit the two pieces are combined with each other The means 200 is brought into contact with one side of the vertical tube.

At this time, the magnetic force member 240 is mounted to the outside of the support frame 210 so that the combined crushing means 200 is in close contact with one side of the vertical tube. Here, the magnetic force member 240 may be implemented as a permanent magnet or an electromagnet, and as the motor implemented by the first driving member 230 rotates, the magnetic force member 240 may be in close contact with one side of the vertical tube and drive in a vertical direction by riding on sidewalls. Will be. At this time, the magnetic force of the magnetic member 240 will have a magnetic force enough to bear the weight of the traveling mechanism.

Through such a configuration and operation process, obstacles existing in the driving direction of the driving device can be removed regardless of the position, and when the obstacles are not easy to be removed or when driving various types of pipes, the effect can be expected. have.

The foregoing merely shows specific embodiments of the obstacle removing and driving assistance device.
