DETAILED DESCRIPTION

[0019] The following will be combined with the drawings of the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] This embodiment provides a device for transporting penstock tiles, such as Figure 1 and Figure 2 As shown, the device for transporting penstock tiles comprises a track 2 and a transport trolley 1 that can move on the track 2. The track 2 is made of I-beam track, which is made of commercially available P24 type track material; a set of tracks 2 is symmetrically arranged, extending from the outside of the four modified derricks to the bottom of the winch inside. Considering the problem of fixing the I-beam track to the ground, as shown in FIG. Figure 1 and Figure 2 As shown, the track 2 also includes a track support frame 6 for supporting the I-beam track. Several groups of track support frames 6 are fixedly welded to the bottom of the I-beam track at equal intervals, and each group of track supports is a triangular structure; the track support includes a column 7 made of a square steel tube, the top of the column 7 is welded and fixed to the I-beam track, and a fixed cross brace 8 is welded to one side of the bottom, and the fixed cross brace 8 is made of channel steel and extends horizontally outward toward the fixed cross brace 8. An oblique brace 9 made of channel steel is provided between the column 7 and the fixed cross brace 8, and the two ends of the oblique brace 9 are respectively welded and fixed to the protruding end of the fixed cross brace 8 and the top of the column 7; further, a through hole can be provided on the fixed cross brace 8 to cooperate with the embedded bolts on the ground to fix the position. In addition, considering that the maximum displacement of the transport trolley 1 is limited, it is placed off the track 2, such as Figure 2 As shown, in this embodiment, maximum displacement blocks 10 are welded and fixed on the tops of both ends of the I-beam rail.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the transport trolley 1 in this embodiment includes a car body 3 with a rectangular frame structure, and running wheels 4 installed at the four corners of the bottom of the car body 3. The running wheels 4 are finished equipment according to whether the P24 type track material is a finished product. The rectangular frame structure of the car body 3 includes I20 I-beam beams 11 located on the left and right sides of the car body 3, and a number of steel plates 12 fixedly installed horizontally and vertically between the I20 I-beam beams 11 on the left and right sides, and the thickness of the steel plates 12 is 30mm; the length and width dimensions of the rectangular frame structure of the car body 3 must meet the length and width dimensions greater than the flat length and width dimensions of the steel pipe tile 5, and the spacing of a group of tracks 2 is determined according to the width dimension of the car body 3; the running wheels 4 are fixedly installed at the bottom of the I-beam beams 11 on the left and right sides.

[0022] like Figure 2 As shown, when the steel pipe tile 5 is transported by the device for transporting pressure steel pipe tiles, the transport trolley 1 is first manually moved on the track 2 to the outside of the four-type modified derrick, the car body 3 forms a placement platform for the steel plate tiles, and the single steel pipe tile 5 is lifted one by one onto the transport trolley 1 by a crane; to avoid deformation of the steel pipe tile 5, it is necessary to place it flat on the transport trolley 1 with its arc-shaped opening facing upward, and then the transport trolley 1 is manually moved on the track 2 to transport the steel pipe tile 5 to the bottom of the winch in the four-type modified derrick, and then the 2JK-3*1.5P lifting winch is used to complete the turning over of the steel pipe tile 5, thereby realizing the positioning and turning over of the steel pipe tile 5 in a small space, so as to facilitate the subsequent circular welding in the hole and the welding between pipe sections of the cylindrical steel pipe structure.

[0023] Furthermore, considering the safety issues of the steel pipe tile 5 during the movement of the transport trolley 1 on the track 2, in this embodiment, a limiting assembly 13 capable of limiting the position of the steel plate tile is also provided on the rectangular frame structure of the vehicle body 3. Figure 1 , Figure 2 and Figure 4 As shown, the limiting assembly 13 is composed of four sets of wedge-shaped limiting blocks 14, and the bottom of each limiting block is slidably mounted on the I-beam beam 11 on the left and right sides of the vehicle body 3 through a clamping plate 15; the clamping plate 15 is threadedly connected with a positioning bolt 16, and the bolt can pass through the clamping plate 15 and abut against the I-beam beam 11. Before the steel pipe tile 5 moves on the track 2 through the transport trolley 1, the four sets of wedge-shaped limiting blocks 14 are used to limit the steel pipe tile 5 to prevent it from sliding off the transport trolley 1 and causing a safety accident.
