The horizontal stop structure cooperates with the lower end of the transported piece, and the vertical stop structure 122 cooperates with the upper end of the transported piece.

[0040] The frame bodies 10 are arranged in a first direction, which is perpendicular to the extending direction of the vertical parts 12 and the extending direction of the horizontal parts 11. The long connecting member 20 connects the frame bodies 10.

[0041] As shown in Figure 1 and Figure 2 , the first direction can be the left-right direction, the extending direction of the vertical parts 12 can be the up-down direction, and the extending direction of the horizontal parts 11 can be the front-back direction. The frame bodies 10 are arranged in the left-right direction.

[0043] The long connecting member 20 can be a section steel, a sheet metal member, a welded member, etc.

[0044] As shown in Figure 1 and Figure 2 , the long connecting member 20 is a section steel, for example, a first hollow pipe 21 and a second hollow pipe 22 with circular cross sections, the first hollow pipe 21 passes through each horizontal part 11 in sequence, and the second hollow pipe 22 passes through each vertical part 12 in sequence, so that the frame bodies 10 form a whole.

In this way, the tile is arranged obliquely relative to the horizontal body 111 or the vertical body 121, and the tile is limited and constrained at the two positions of the upper end and the lower end, so that the tile can be stably fixed on the frame body 10, and the tile is prevented from being collided, extruded or rubbed, which helps to ensure the integrity of the tile; meanwhile, the labor intensity of the carrying personnel is greatly reduced. In addition, the obliquely arranged tile is beneficial to scraping the tile, so that the tile can be attached with the slurry in each area, thereby reducing the occurrence of the tile hollow phenomenon.

[0048] As an implementation manner, the upper surface of the horizontal body 111 is provided with at least two horizontal stop structures, and each horizontal stop structure is arranged at intervals along the extension direction of the horizontal body 111; the stop piece 1222 reciprocates in the vertical direction and hovers at a preset position, and the stop piece 1222 is in stop cooperation with the upper end of the to-be-transported piece.

[0050] As shown in Figure 8 and Figure 9 , the vertical stop structure 122 includes a sliding piece 1221, a stop piece 1222 and a transition connecting piece 1223. The sliding piece 1221 slides on the vertical body 121, and the sliding piece 1221 can be sleeved on the vertical body 121. A bolt passes through the sliding piece 1221, and the end of the bolt abuts against the side surface of the vertical body 121. By loosening the bolt, the sliding piece 1221 can slide on the vertical body 121; by tightening the bolt, the sliding piece 1221 can hover at a preset position.

[0051] The transition connecting piece 1223 is an L-shaped bent plate including a first part and a second part. The first part is connected to the outer surface of the side wall of the sliding piece 1221. Two transition connecting pieces 1223 are arranged at intervals in the up-down direction, and the second parts of the two transition connecting pieces 1223 are parallel to each other. The gap between the two second parts is provided with the stop piece 1222. The stop piece 1222 is hinged to the transition connecting piece 1223, so that the stop piece 1222 has a stop position and a avoiding position, and the stop piece 1222 can be switched between the stop position and the avoiding position.

[0052] In combination with Figure 5 , Figure 6 and Figure 8As shown in the stopper 1222 is in the stop position, the stopper 1222 is located between the stop protrusion 1111 and the vertical body 121, the stopper 1222 is matched with the upper end of the tile; as shown in combination Figure 5 、 Figure 6 and Figure 9 As shown in the stopper 1222 is in the avoidance position, the stopper 1222 is not located between the stop protrusion 1111 and the vertical body 121, that is, the stopper 1222 is flush with the vertical body 121 in the front and back direction, or the stopper 1222 is located at the rear side of the vertical body 121, so that when the tile is placed on the frame body 10, the stopper 1222 is avoided from colliding with the tile, thereby facilitating the placement of the tile or ensuring the integrity of the tile.

[0053] In the scenario shown in Figure 5 , the lower end of the tile is placed in the stop recess 112; as shown in Figure 6 , if the size of the tile increases, the lower end of the tile can be abutted with the stop protrusion 1111, and the position of the sliding piece 1221 on the vertical body 121 is adjusted so that the stopper 1222 is matched with the upper end of the tile. In this way, the transport device can be adapted to transport tiles of various sizes, improving the use of the transport device.

[0054] As an implementation manner, as shown in Figures 5-7 , the stop recess 112 is provided with a folded ear 1121, and the upward opening of the stop recess 112 includes a first edge 11201, which is arranged close to the vertical body 121 and extends upwardly and obliquely to the vertical body 121 to form the folded ear 1121.

[0055] As shown in Figure 2 , the horizontal body 111 further includes a sheet metal groove 112, and the opening of the sheet metal groove 112 is provided with a folded ear 1121.

[0056] The folded ear 1121 of the sheet metal groove 112 can protect the tile and avoid scratching the tile by the edge of the opening, thereby helping to ensure the integrity of the tile.

[0057] As an implementation manner, the transporting device further comprises a first locking member 41. The first locking member 41 is connected to the horizontal body 111 and cooperates with the first hollow pipe 21 to limit the freedom of the horizontal body 111 in the direction of the axis of the first hollow pipe 21. In this way, the distance between the two adjacent frame bodies 10 is kept stable, thereby ensuring the stability of the whole transporting device. Meanwhile, the distance between the two adjacent frame bodies 10 can also be adjusted to adapt to ceramic tiles of different sizes.

[0058] As shown in Figure 4 , the transporting device is provided with two frame bodies 10.

[0062] As shown in Figure 5 or Figure 6 , a rubber pad is arranged on the region where the vertical body 121 contacts with the tile, and the rubber pad contacts with the upper end of the tile, thereby avoiding the rigid collision between the upper end of the tile and the vertical body 121, and thus helping to ensure the integrity of the tile.

[0063] A rubber pad is wrapped on the stop protrusion 1111 and laid in the stop recess 112. The rubber pad contacts with the lower end of the tile, thereby avoiding the rigid collision between the lower end of the tile and the horizontal body 111, and thus helping to ensure the integrity of the tile.

[0064] Of course, it can be understood that the buffering member 50 can be a silica gel pad, an EVA rubber pad, a polyurethane foam pad, etc. in addition to the rubber pad, and the present embodiment does not limit this.

The carrying process needs the assistance of two carrier personnel. The ceramic tile carrying efficiency is low, and the labor intensity of the carrier personnel is large.

[0068] And by loosening the second fastener 42, the vertical body 121 and the horizontal body 111 are separated from each other. As shown, the horizontal body 111 can be connected with the carrier 70 by means of the auxiliary connecting piece 60. As shown, Figure 11 As shown, the auxiliary connecting piece 60 is provided with a connecting groove 61 and a hook groove 62, the vertical beam 71 of the carrier 70 is embedded in the connecting groove 61, and the hook groove 62 is hung on the first hollow tube 21. Under the assistance of the second handle 72 on the carrier 70, the carrier 70 can be freely moved through the rolling piece 30 under the horizontal body 111. In this way, only one carrier personnel is needed, and the labor intensity of the carrier personnel is reduced.
