Furthermore, when the cast pipes are stored, the cast pipes are stored in a cross-shaped stacked mode, after one layer of cast pipes is placed, the next layer of cast pipes is placed, the pipe placing platform 1 can be rotated through the lifting and rotating mechanism 6, the axis direction of the cast pipes on the pipe placing platform 1 is parallel to the axis direction of the cast pipes on the layer, and the cast pipes can be placed and placed more conveniently.

As a specific embodiment of the lifting and rotating mechanism 6, please refer to fig. 1 to 5, the lifting and rotating mechanism 6 includes a third motor 61, a sleeve 63, a lifting and sliding sleeve 64, a fourth gear 66 and a fourth motor 69; the third motor 61 is fixed on the walking trolley 4, and the output end of the third motor 61 is provided with a second gear 62; the sleeve 63 is rotatably connected to the walking trolley 4, a third gear meshed with the second gear 62 is arranged on the outer side of the sleeve 63, and an internal thread penetrating through the sleeve 63 is arranged on the inner side of the sleeve 63; the lifting sliding sleeve 64 and the walking trolley 4 have slidable freedom in the vertical direction, and the outer surface of the lifting sliding sleeve 64 is provided with an external thread meshed with the internal thread of the sleeve 63; the sleeve 63 rotates to drive the lifting sliding sleeve 64 to move up and down so as to drive the pipe placing platform 1 and the supporting platform 3 to lift and descend simultaneously; one end of the fourth gear 66 is fixed on the lifting sliding sleeve 64, and the other end is rotatably connected to the supporting platform 3; and the fourth motor 69 is fixedly connected to the supporting platform 3, a fifth gear 68 is arranged at the output end of the fourth motor 69, and the fourth gear 66 is meshed with the fifth gear 68, so that the supporting platform 3 rotates around the fourth gear 66 to drive the pipe placing platform 1 to rotate simultaneously.

Specifically, the third motor 61 drives the second gear 62 to rotate, the third gear on the sleeve 63 is meshed with the second gear 62 to rotate, wherein the sleeve 63 is rotatably connected to the traveling trolley 4 through a bearing, i.e., the sleeve 63 only rotates relative to the traveling trolley 4 and does not move in the vertical direction, and because of the internal thread inside the sleeve 63 being connected with the external thread of the lifting sliding sleeve 64, the lifting sliding sleeve 64 in threaded connection with the sleeve 63 moves up and down at the moment, so the fourth gear 66 fixedly connected with the lifting sliding sleeve 64 goes up and down along with the lifting sliding sleeve 64, and further the supporting platform 3 rotatably connected with the fourth gear 66 and the pipe placing platform 1 above the supporting platform 3 go up and down along with the lifting sliding sleeve 64 at the same time. Further, the fourth motor 69 drives the fifth gear 68 to rotate, the fourth gear 66 is meshed with the fifth gear 68 to rotate, because the fourth gear 66 is fixed on the lifting sliding sleeve 64 and is rotatably connected to the supporting platform 3, the fifth gear 68 is driven by the fourth motor 69 to rotate around the fourth gear 66, that is, the supporting platform 3 rotates around the lifting sliding sleeve 64, that is, the supporting platform 3 and the pipe placing platform 1 rotate relative to the lifting sliding sleeve 64, because the lifting sliding sleeve 64 and the traveling trolley 4 only have freedom of up-and-down movement, and finally, the pipe placing platform 1 and the supporting platform 3 rotate relative to the traveling trolley 4. Of course, in order to rotate the tapping platform 1 by 90 degrees more precisely, a second signal receiver 672 may be arranged on the lower end surface of the fourth gear 66, a diameter line of the fourth gear 66 where the second signal receiver 672 is located is perpendicular to a diameter line of the fourth motor 69, a second signal emitter 671 is arranged on the lower end of the output shaft of the fourth motor 69, when the tapping platform 1 rotates by 90 degrees, the second signal emitter 671 on the fourth motor 69 emits a signal to the second signal receiver 672, then the fourth motor 69 stops rotating, and the rotation process of the tapping platform 1 is ended. It should be noted that, considering that the weight of the transported cast pipe may be relatively large, in order to increase the stability of the lifting and rotating mechanism 6, a guiding sleeve 65 is disposed in the lifting and sliding sleeve 64, and the guiding sleeve 65 is fixed on the traveling trolley 4 and is located inside the lifting and sliding sleeve 64 for guiding the lifting and sliding sleeve 64, wherein the guiding sleeve 65 is quadrangular, and a square groove in sliding fit with the guiding sleeve 65 in the vertical direction is disposed inside the lifting and sliding sleeve 64, that is, the lifting and sliding sleeve 64 can move up and down along the guiding sleeve 65, but cannot rotate relatively.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
