Description

Technical Field

[0001] The utility model relates to the technical field of hydropower station construction, in particular to an asphalt paving device and system for hydropower station dam construction. Background Art

[0002] During the construction of the hydropower station dam, after the main body of the dam is completed, it is necessary to lay a steel mesh on its slope and then spread asphalt. At present, in the process of spreading asphalt on the dam slope, a paving machine and a pressing machine are needed to spread and press the material respectively, but the inclination angle of the dam body is large. Therefore, generally speaking, the paving machine and the pressing machine cannot climb from the bottom of the dam to the top by themselves. Auxiliary power equipment is needed. During the process of moving on the dam slope, cables are used to provide auxiliary power to achieve smooth uphill and downhill.

[0003] Therefore, at present, when paving and pressing materials on the dam slope, the only way is to use two cables to respectively control the auxiliary paving machine and the pressing machine for staggered construction. However, the staggered construction will cause the asphalt material to be laid for a period of time before the pressing machine can press the material. Due to the large inclination angle of the dam slope, the material will not be pressed in time, resulting in a small part of the particles rolling down. In addition, the paving machine and the pressing machine still need operators to drive, and there are certain safety hazards.

[0004] Based on this, the inventor has designed an asphalt paving device and system for hydropower station dam construction on the basis of the original design to solve at least one of the above problems. Utility Model Content

[0037] Embodiment 1:

[0038] like Figure 1 As shown, this embodiment provides an asphalt paving and pressing device for hydropower station dam construction, including a support frame 1, a paving structure and a pressing mechanism, wherein:

[0039] A cable installer 101 is provided at one end of the support frame 1 away from the material pressing mechanism;

[0040] The pressing mechanism includes a pressing wheel 21 rotatably connected to the support frame 1 at both ends;
