Wherein, both ends of the first transmission shaft 444-1 are installed on the hood 442, the first bushing 444-2 is supported on the guide hood 434 by the bushing seat 444-6, the second transmission shaft 445-2 is also installed on the hood 442, in the process that the guide 43 realizes the clamping and the releasing of the pipeline 3 through the displacement, the guide 43 drives the first bushing 444-2 and the first bevel gear on the first bushing 444-2 to synchronously displace through the bushing seat 444-6, in the process, the shaft sliding block 444-5 displaces in the shaft surface sliding groove 444-4, and the transmission state between the forward and reverse rotation motor 441 and the guide rotating shaft 433 is ensured.

Specifically, the guide hoods 434 are disposed so that when the guide 43 clamps the pipe 3, a space is provided between the two guide hoods 434. Synchronous board 423 is connected through the connecting block on the end that stretches out of electric telescopic handle 421, synchronous board 423 sets up in the interval, and synchronous push pedal 422's one end and synchronous board 423 normal running fit. At this time, the displacement slide rails 443 are spaced apart from each other, and the spacing between the two displacement slide rails 443 is used for passing through the connection block when the synchronization plate 423 displaces and drives the synchronization push plate 422 to move.

The hood 442 corresponds to the part of the upper receiving chamber, the surface of which is arranged in the shape of a circular arc centered on the axis of the pipe 3 in the vertical section suspended between the beam 12 and the ground.

The guide wheel 41 is fixed to the top of the hood 442. In this example, when the print head 2 is displaced along the length direction of the beam 12, the guide wheels 41 and the guide 43 can swing integrally along with the pipeline 3, so that the distortion of the pipeline 3 is reduced, and a good material conveying effect is guaranteed. Especially in the building printing process, because the movement space of the printing head 2 spans a large distance, the twisting transition of the pipeline 3 will directly affect the material supply of the printing head 2, and therefore, after the scheme of the example is adopted, the whole guide 43 can swing along with the pipeline 3.

As one example thereof, in a manner in which the pipe guide 4 is prefabricated to be supported on the intermediate beam 13, the pipe guide 4 is supported at one end of the intermediate beam 13, and the pipe guide 4 is located outside the cross beam 12 corresponding to the end of the intermediate beam 13.

The number of the suspension beams 6 is two, and the suspension beams are distributed on both sides in the width direction.

By arranging the tube guide 4 on the intermediate beam 13, when the intermediate beam 13 is displaced on the cross beam 12, the tube guide 4 is displaced in a synchronous manner, so that the tube guide 4 supports the tube 3 with a displacement stroke of the print head 2 in a length direction of the cross beam 12. In this state, when the print head 2 is actuated, the suspended portion of the tube 3 only needs to satisfy the displacement stroke of the print head 2 on the intermediate beam 13 by displacement. And corresponding to the displacement process of the printing head 2 in the length direction of the cross beam 12, the whole displacement of the part between the pipeline guide device 4 and the material station is matched through the pipeline guide device 4 by the middle beam 13. Reduce 3 motion degrees of pipeline when beating printer head 2 and remove, improve the stability of pipeline 3 self and the better stability of being connected between protection pipeline 3 and the feed inlet, guarantee good feed effect for beating printer head 2.

The pipe guide 4 is arranged to be displaceable on one of the cross beams 12 in such a way that the pipe guide 4 is preformed to be supported on one of the cross beams 12. In this way, the position of the pipe guide 4 can be adjusted in real time according to the position of the intermediate beam 13 on the cross beam 12; or the pipeline guide device 4 is arranged at a proper position on the cross beam 12 in advance according to the extending direction of the pipeline 3; or the pipeline 3 is arranged at a proper position on the cross beam 12, so that the pipeline 3 can better avoid a construction area below the platform 1, and construction is facilitated. Wherein:

as a first condition, a displacement rail 121 is provided on the cross beam 12, the pipeline guide 4 is slidably engaged with the displacement rail 121, and the pipeline guide 4 is fixed at a designated position of the displacement rail 121 by a fixing assembly 45.
