Referring to fig. 1 and 2, in an embodiment of the present invention, the precast pile conveying mechanism 1 is laid on a hard bearing surface (such as a metal plate surface, a cement ground surface, or a compacted earth surface) in a factory, and includes a mold-stripping pile rolling device (not shown), a conveying line 12, a plurality of rotating rollers 111, and a transverse positioning mechanism 13. The demolding pile rolling device is used for transferring the formed precast pile from the mold to the conveying line 12 and is positioned at the initial end of the conveying direction of the conveying line 12.

Referring to fig. 1 and 2, the conveying line 12 is two parallel conveying frames laid on the hard bearing surface, the conveying frames may be made of materials with certain strength and toughness, such as iron and steel, when the conveying line is laid, it should be ensured that the contact surfaces for bearing the rotating rollers 111 on the conveying line 12 are on the same horizontal plane, and the parallelism is ensured, and the height of the conveying line 12 may be set according to actual production conditions. The plurality of rotating rollers 111 are longitudinally arranged at intervals along the conveying line 12, and the plurality of transverse positioning mechanisms 13 are positioned on one transverse side of the conveying line 12 and are longitudinally arranged at intervals along the conveying line 12; the rotating rollers 111 are formed with radial projections 1111 at the other lateral side, and the radial projections 1111 on each rotating roller 111 are uniform and flush in the longitudinal direction of the feed line 12.

In the structure, a plurality of rotating rollers 111 are parallel to each other, the rotating rollers 111 are arranged on the conveying line 12 and can rotate along the axis of the rotating rollers, and the rotating rollers 111 rotate to drive the precast pile to move forwards; the utility model discloses a precast pile conveying mechanism 1 has realized the mechanization that the precast pile carried, has reduced the cost of labor, has improved work efficiency.

Further, referring to fig. 1 and 3, a radial protrusion 1111 is formed on one axial side of the rotating roller 111, and the radial protrusion 1111 is located on one lateral side of the conveying line 12 opposite to the lateral positioning mechanism 13. The radial protrusion 1111 and the transverse positioning mechanism 13 which are arranged oppositely enable the precast pile to be limited in the conveying process, the central axis of the precast pile is always kept consistent with the conveying direction, the precast pile is prevented from rolling and falling in the conveying process, and the whole conveying process is safer. The radial protrusion 1111 with the positioning function is arranged on the rotating roller 111 and is a part of the rotating roller 111, and a positioning mechanism is not required to be additionally arranged, so that the structure is simple, and the manufacturing cost is saved; in addition, in the installation process of the precast pile conveying mechanism 1, the positioning mechanisms are arranged on the rotating rollers 111, so that the positioning mechanisms can be adjusted more conveniently, and the positioning mechanisms are ensured to be longitudinally flush.

Referring to fig. 1 and fig. 2, in the present embodiment, four rotating rollers 111 are combined to form a conveying device group 11, and each conveying device group 11 further includes a driving mechanism 112 and a transmission mechanism 113 for driving and connecting two adjacent rotating rollers 111; in a conveying device group 11, a rotating roller 111 positioned at the outermost end of the conveying device group 11 is connected with a driving mechanism 112, one transverse end of the rotating roller 111 extends outwards to form an extending end 1112 connected with a transmission mechanism 113, and each rotating roller 111 moves synchronously under the action of the transmission mechanism 113.

In the above structure, the driving mechanism 112 is a power source for providing the operation of the transmission mechanism 113, and is a driving motor in the present embodiment. In this embodiment, each set of conveying devices 11 includes four rotating rollers 111, one driving mechanism 112 and a transmission mechanism 113, and the number of the rotating rollers 111 and the driving mechanism 112 and the distance between the rotating rollers 111 can be configured according to actual production conditions. One end of each of the rotating rollers 111 in the lateral direction is formed with an extended end 1112 for connection with the transmission mechanism 113. The transmission mechanism 113 is in transmission connection with the driving mechanism 112 and each rotating roller 111, and each rotating roller 111 is synchronously operated under the action of the driving mechanism 112 through the transmission mechanism 113. During actual operation, the driving mechanisms 112 in the conveying device groups 11 operate at the same speed to ensure that the rotating rollers 111 of the conveying device groups 11 operate at the same speed.

The arrangement of the conveying device group 11 enables each rotating roller 111 to obtain the power provided by the driving mechanism 112 through the transmission mechanism 113, that is, each rotating roller 111 has the power for transmitting the precast pile, so that the power in the conveying process is increased, and the phenomenon that the precast pile and the rotating roller 111 slip due to insufficient power of the precast pile conveying mechanism 1 is avoided. The powered arrangement of each rotating roller 111 has a more obvious effect in the conveying process of the variable-section piles. Because each cross section of the variable cross-section pile is changed in the length direction of the pile, only the large cross-section pile section is in contact with the conveying device group 11 in the actual conveying process, so that the contact area is reduced; furthermore, if each rotating roller 111 does not have power for conveying the precast pile, it is difficult to ensure the number of rotating rollers 111 having power transmission, which are in contact with the precast pile, resulting in insufficient power for conveying the precast pile or a serious slip phenomenon during conveying the precast pile, which results in energy waste. In the embodiment, the four rotating rollers 111 are provided with one driving mechanism 112, so that the rotating rollers 111 can obtain sufficient power, and excessive power loss generated between the rotating rollers 111 and the transmission mechanism 113 is avoided, so that the power of the subsequent rotating rollers 111 is insufficient.

Referring to fig. 4, the positioning seat 121 has a through hole for the rotating roller 111 to pass through, and a rolling bearing connected and matched with the rotating roller 111 is disposed in the through hole, so that the rotating roller 111 can rotate around its own axis.

In addition, in the installation process of each conveying device group 11 of the precast pile conveying mechanism 1, the distance between the rotating rollers 111 can be adjusted according to the length of the transmission mechanism 113 or the tightness required to be matched with the rotating rollers 111, so that on one hand, the installation of the transmission mechanism 113 is more convenient, on the other hand, the connection and matching of the transmission mechanism 113 and the rotating rollers 111 are more convenient and reliable, and in the subsequent use process, the effective matching of the transmission mechanism 113 and the rotating rollers 111 can be ensured by adjusting the distance of the rotating rollers 111.

In addition, the main body of the rotating roller 111 is a cylinder, and compared with rollers in other shapes, on one hand, the universality of the precast pile is improved, particularly, the appearance of the precast pile tends to be diversified, on the other hand, the proportion of the square pile in the precast pile is gradually increased, and the contact area can also be increased in the conveying process of the square pile by the aid of the structural design.
