Detailed Description

Example 1: the device comprises a transverse central cylinder shaft 1, a sleeve connecting pipe 2 is sleeved outside the central cylinder shaft 1, two ends of the sleeve connecting pipe 2 are respectively fixed with a connecting seat 4, a bearing 3 is arranged between the connecting seats 4 at two ends and the central cylinder shaft 1 or between the sleeve connecting pipe 2 and the central cylinder shaft 1, and a sealing structure of the bearing 3 or a sealing bearing 3 which is directly arranged is arranged.

As shown in fig. 2, a plurality of fixed diameter rods 5 are uniformly distributed and fixed on the periphery of the connecting seat 4 along the radial direction, and the tail ends of the fixed diameter rods 5 are respectively hinged with a swing rod 7 through a middle pin shaft 6. Meanwhile, a support of the fixed diameter rod 5 and the swing rod 7 is required to be provided with a torsion spring or a tension spring with strong force, so that the swing rod 7 can swing along the radial direction, namely, the swing rod 7 can be unfolded under the action of the torsion spring or the tension spring and is coaxial with the fixed diameter rod 5 after being unfolded. Obviously, the radius r0 of the unfolded swing link 7 = the length a of the fixed diameter rod 5 + the length b of the swing link 7; after the swing rod 7 is compressed, the radius rx is less than the length a of the fixed-diameter rod 5 and the length b of the swing rod 7. It can be seen that the device is suitable for a range of diameters d of the duct 23 which satisfies: the length a of the fixed diameter rod 5 is less than d and less than the length a of the fixed diameter rod 5 and the length b of the swing rod 7.

Meanwhile, the tail end of each oscillating bar 7 is respectively provided with a blade shaft 9, the outer side of each blade shaft 9 is fixed with a spiral propelling wheel 8, the spiral propelling wheel 8 is made of rubber or nylon, and friction grains can be arranged on the edge of the spiral propelling wheel 8 to improve the wall grabbing performance of the spiral propelling wheel. It can be seen that the screw propulsion wheels 8 can be pressed against the inner wall of the pipe 23 by the oscillating bars 7. When the connecting seat 4 rotates to drive the fixed diameter rod 5 and the swing rod 7 to rotate together, the spiral propelling wheel 8 can slowly advance along the axial direction of the pipeline 23. Thus, the device can automatically advance and continuously work along the pipeline 23, when the sludge amount is large, the device is blocked and can still rotate in place until the sludge in front is pumped out and emptied and then moves continuously. The existing dredging device in the walking underground pipeline needs to prevent a walking unit from skidding by increasing the gravity of equipment, most wheels are in an in-situ skidding state due to the fact that a large amount of slurry exists at the bottom of the inner wall of the pipeline, the wheels cannot move forwards effectively, and a suction head is not in complete contact with the slurry. However, in the embodiment, the spiral propelling wheels can be uniformly distributed on each side surface of the inner wall of the pipeline, at least the spiral propelling wheel positioned on the side surface of the upper part is arranged, and the problem of in-situ slip caused by slurry factors can be avoided. And this equipment relies on powerful torsional spring to support, need not consider to increase equipment counter weight factor, so equipment can realize small-size and lightweight.

The vertical pipe and the suction head are positioned at the front side of the advancing direction, so that the vertical pipe and the suction head can be in direct contact with a mud part, namely, the vertical pipe and the suction head are greatly restrained by mud, and the swing rods and the spiral propelling wheel positioned at the rear side of the suction head are little or have no mud, so that the restraint force is small.

It can be seen that each fixed diameter rod 5 and each swing rod 7 can be uniformly supported on the inner wall of the pipeline 23 under the action of the corresponding powerful torsion springs, so that the central cylindrical shaft 1 is basically positioned at the axis position of the pipeline 23.

As shown in figure 1, the far end of the central cylinder shaft 1 is connected with an angle joint 10, a vertical pipe 11 is vertically fixed on the angle joint 10, and the tail end of the vertical pipe 11 is provided with a suction part.

Under the state of a starting motor 17, a transmission output shaft 19 drives a back-motion gear on the connecting seat 4 to rotate, so that the connecting seat 4, the fixed diameter rod 5 and the oscillating bar 7 are driven to rotate, and the spiral propelling wheel 8 is pressed and contacted with the inner wall of the pipeline 23, so that the spiral propelling wheel 8 is forced to roll along the inner wall of the pipeline 23 in the rotating process of each component, the contact position of the spiral propelling wheel 8 and the inner wall of the pipeline is different, and the spiral propelling wheel can axially move along the pipeline while rolling. The motor is operated to advance the apparatus slowly forward. Because the closing cap, the gear box and the motor are respectively positioned below the central cylinder shaft 1, the vertical pipe 11, the inner sleeve 12 and the suction head 13 are respectively positioned below the central cylinder shaft 1, and the central through shaft is connected with the rotating parts through the bearing 3, the rotating parts can not drive the fixed parts positioned below the central cylinder shaft 1 to rotate or swing in the slow rotating process.

Meanwhile, the proximal end of the central cylinder shaft 1 is connected with a suction pipe 14, and the suction pipe 14 extends to the ground.
