[0002] When using rockfill concrete dam construction technology to build a dam, it is necessary to transport the stones to the top of the dam body, and then use a placing machine to pour self-compacting concrete. After pouring is completed, the above construction steps are repeated again to achieve layer-by-layer stacking construction.

[0003] At present, during the construction process, engineering vehicles are mostly used to transport stones on the storage surface. The frequent back and forth driving of engineering vehicles on the dam storage surface can easily cause the already laid rockfill layer to be damaged. At the same time, it is also necessary to reserve necessary operation paths and space for engineering vehicles, resulting in reduced construction efficiency. The existing dam bodies all have a certain slope. When using traditional belt conveyors to transport stones on the slope, the stones are easy to slip off the belts, which poses a greater risk of accidents. Summary of the invention

[0024] The specific implementation of the present invention is described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention provides a stone conveying device for dam construction, which is arranged on a belt conveyor. The belt conveyor is set up at the upper and lower ends of the dam slope. The belt conveyor includes a conveying belt 2 arranged on a frame 1. Figure 1-4 It includes multiple groups of limiting structures, which are evenly arranged on the conveyor belt 2. Each group of limiting structures includes a fixed rod 3, a hinge 4, a load-bearing plate 5 and a cross baffle 6. The fixed rod 3 is fixedly arranged on the conveyor belt 2 along the width direction of the conveyor belt 2. The fixed rod 3 is connected to the end of the load-bearing plate 5 through the hinge 4. The load-bearing plate 5 can be flipped to either side of the hinge 4; the load-bearing plate 5 flips toward the high side of the slope, and the middle position of the upper surface of the load-bearing plate 5 is fixedly connected to the cross baffle 6, and the plate surface of the cross baffle 6 is parallel to the length direction of the fixed rod 3.

[0026] When the stone transmission device for dam construction is used, the belt conveyor is started, the conveying belt 2 moves upward, and the workers place the stones on the bearing plate 5 at the lower part of the slope. The cross baffle 6 is used to prevent the stones from sliding down and limit the stones in the groove with the opening upward formed by the bearing plate 5 and the cross baffle 6; wherein, since the cross baffle 6 is located in the middle of the bearing plate 5, when the stone has a tendency to flip in the reverse conveying direction due to the large slope angle, the part of the bearing plate 5 under the cross baffle 6 provides a larger resistance arm, which can prevent the bearing plate 5 and the stone from flipping; the fixing rod 3 is transversely fixed on the flexible conveying belt 2, which can prevent the conveying belt 2 from tilting upward on both sides in the width direction, causing the conveying belt 2 to flip to one side, thereby improving the stability of the stone transmission;

[0027] The stone transmission device used in the dam construction is a simple modification of the belt conveyor, which enables the belt conveyor to be able to transmit larger stones. This not only prevents the stones from slipping during the transmission process, but also improves safety and speeds up the construction progress.

[0028] Preferably, if Figure 2-4 A limiting rod 7 parallel to the fixing rod 3 is fixedly provided on the conveying belt 2, and the limiting rod 7 can be clamped in a limiting groove 8 provided on the lower surface of the carrying plate 5; there are multiple limiting rods 7, and the multiple limiting rods 7 are respectively arranged on both sides of the edge of the conveying belt 2, and the lower surface of the carrying plate 5 is provided with multiple limiting grooves 8, and each limiting groove 8 can clamp one limiting rod 7.

[0029] The purpose is to prevent the stone from not being placed at the center of the cross baffle 6, which causes the stone to deflect and roll during transportation; the limit rods 7 on both sides can be engaged with the multiple limit grooves 8 to prevent the bearing plate 5 from deflecting in the transmission direction.

[0030] Preferably, if Figure 2 and Figure 5-7 The stone transmission device for dam construction also includes a receiving device for receiving stones, the receiving device is arranged on the upper surface of the slope at a high place, the receiving device includes a fixed frame 9, a rotating roller 10, a plate body 11, a torsion spring and a platform 12, the fixed frame 9 is fixed at the output end of the belt conveyor, the fixed frame 9 is rotatably provided with a rotating roller 10, the rotating roller 10 is fixedly connected to the plate body 11, the plate body 11 is parallel to the rotating roller 10, the rotating roller 10 is sleeved with the torsion spring, one end of the torsion spring is connected to the rotating roller 10, and the other end of the torsion spring is connected to the fixed frame 9, the torsion spring ensures that the plate body 11 faces the upper side of the platform 12, the platform 12 is arranged on the side of the fixed frame 9 away from the conveying belt 2, and the upper surface height of the platform 12 is lower than the highest point of the rotating roller 10;

[0031] During the process of the conveyor belt 2 carrying the fixed rod 3 turning at the output end of the conveyor, Figure 5-Figure 6 The bearing plate 5 and the stones on the bearing plate 5 move downward (during which the bearing plate 5 rotates clockwise around the fixing rod 3), and the lower surface of the bearing plate 5 abuts against the end of the plate body 11. Figure 6-Figure 7 The stone presses down the supporting plate 5 and the plate body 11 at the same time. At this time, the stone slides from the supporting plate 5 to the plate body 11. The inclination angle of the plate body 11 decreases due to the gravity of the stone. At the same time, the stone slides from the plate body 11 to the platform 12. During this period, the supporting plate 5 and the fixing rod 3 continue to move toward the lower end of the belt conveyor driven by the conveyor belt 2. When the supporting plate 5 and the fixing rod 3 move to the lower end of the belt conveyor, the worker rotates the supporting plate 5 clockwise so that the cross baffle 6 faces upward, and the stone can be transported again.

[0032] Preferably, if Figure 5-7 The platform 12 is close to the fixing frame 9, and the upper surface of the platform 12 includes a concave arc surface and a horizontal surface. The upper end of the concave arc surface receives stones, and the lower end of the concave arc surface is smoothly connected to the horizontal surface.

[0033] The purpose is to enable the stone to slide down to the horizontal surface of the platform 12 more smoothly.

[0034] Preferably, if Figure 5-7The stone transmission device for dam construction also includes a supporting structure, which includes an electric telescopic rod 13 and an elastic telescopic rod 14. The lower end of the electric telescopic rod 13 is fixed to the upper end of the slope, and the upper end of the electric telescopic rod 13 is fixedly connected to the lower end of the elastic telescopic rod 14. The upper end of the elastic telescopic rod 14 abuts against the lower surface of the plate body 11.

[0035] The elastic telescopic rod 14 is used to prevent the stone from being too heavy and the elastic force of the torsion spring from being insufficient, resulting in the stone being unable to quickly slide onto the platform 12; controlling the extension and retraction of the electric telescopic rod 13 can limit the lowest position of the elastic telescopic rod 14, thereby controlling the minimum tilt angle of the plate body 11.

[0036] Preferably, if Figure 1-2 The frame 1 is rotatably provided with a plurality of rotating shafts 15 , which are all arranged on the inner side of the conveyor belt 2 in parallel with the fixing rod 3 , and the outer periphery of each rotating shaft 15 abuts against the inner surface of the conveyor belt 2 .

[0037] The plurality of rotating shafts 15 are used to provide more stable support for the conveyor belt 2 to prevent the conveyor belt 2 from deformation and tilting.

[0038] Preferably, if Figure 1-2 Side baffles 16 are fixedly provided on both sides of the transverse baffle 6 , respectively. Each side baffle 16 is located on a side of the transverse baffle 6 away from the hinge 4 , and each side baffle 16 is fixedly connected to the upper surface of the bearing plate 5 .

[0039] The purpose is to prevent stones from sliding.

[0040] The method of using the stone conveying device for dam construction of the present invention is as follows:

[0041] First, the belt conveyor starts, and the conveyor belt 2 moves upward;

[0042] Then, workers place stones on top of the bearing plate 5 and the cross baffle 6 at the lower part of the slope;

[0043] Then, during the process of turning at the output end of the conveyor, the stone slides along the bearing plate 5 to the plate body 11, and then slides from the plate body 11 to the platform 12;

[0044] Finally, the load-bearing plate 5 and the fixing rod 3 continue to move toward the lower end of the belt conveyor driven by the conveying belt 2. When the load-bearing plate 5 and the fixing rod 3 move to the lower end of the belt conveyor, the worker rotates the load-bearing plate 5 clockwise so that the cross baffle 6 faces upward, and the stones can be transported again.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
