Embodiment 1

[0019] Embodiment 1: A kind of large-scale hydraulic engineering S-shaped overflow dam surface forming equipment, see figure 1 and figure 2 , two S-shaped guide rails 1 are distributed along the upper part of both sides of the S-shaped overflow dam surface, and the two S-shaped guide rails 1 are set at the same width as the S-shaped overflow dam surface and kept parallel. Each S-shaped guide rail 1 is provided with a side bracket 2 and an end bracket 3 .

[0020] see figure 2 and image 3 , each S-shaped guide rail 1 is equipped with a longitudinal traveling mechanism, each longitudinal traveling mechanism includes an end fixing plate 8 and a horizontal beam 5, and a longitudinal driving mechanism and a braking mechanism are respectively provided (the longitudinal driving mechanism and the braking mechanism are not shown in the figure). brake mechanism), wherein the longitudinal drive mechanism and the brake mechanism can be arranged on the horizontal beam 5. image 3 In...

Embodiment 2

[0024] Embodiment 2: On the basis of Embodiment 1, a mounting base 4 may be provided between the side bracket 2 and the S-shaped guide rail 1 , and a height adjustment mechanism may be provided between the S-shaped guide rail 1 and the mounting base 4 . The height adjustment mechanism is provided with equidistant installation holes on the vertical surface of the installation seat, and the ends of the S-shaped guide rail 1 are installed in the corresponding installation holes by bolts.

Embodiment 3

[0025] Embodiment 3: The content is basically the same as that of Embodiment 1, the difference is that, see Figure 4 and Figure 5 , be fixed with roller seat 14 at connecting rod 6 lower ends, roller seat 14 below is equipped with cylinder by rotating shaft 15, also be equipped with motor 11 on roller seat 14, motor 11 rotating shaft is connected with the rotating shaft 15 transmissions of cylinder. In this embodiment, the drum can always roll along the surface of the overflow dam. In addition, a mechanism for adjusting the lift can also be arranged on the connecting rod 6 .

Abstract

The invention discloses an S-shaped overflow dam surface forming equipment for a large-scale water conservancy project. Two parallel S-shaped guide rails are arranged along the upper part of the S-shaped overflow dam surface; each S-shaped guide rail is equipped with a longitudinal walking mechanism; The longitudinal traveling mechanisms are connected together by crossbeams, horizontal guide rails are arranged at the bottom of the crossbeams, and transverse traveling mechanisms are installed on the horizontal guide rails; a smoothing device is arranged at the bottom of the transverse traveling mechanisms. The horizontal traveling mechanism of the present invention can carry the smoothing mechanism to translate along positions of equal heights, ensuring that the smoothing mechanism has an inconvenient working height, good smoothing effect and fast speed. The invention adopts full machinery to realize the formation of the overflow dam surface, which can realize automatic control, reduce construction cost, reduce manual workload, high quality and high efficiency, and is very suitable for popularization and implementation.

Description

technical field [0001] The invention relates to the technical field of water conservancy project construction, in particular to a concrete curved surface plastering machine used for overflow dam surface construction. Background technique [0002] The overflow dams in large-scale water conservancy projects are generally concrete structures, and the dam surface needs to discharge flood. The overflow dam surface is usually composed of weir crest curved surface, inclined plane and anti-arc curved surface, which is approximately S-shaped. The surface layer of the S-shaped overflow dam is mostly constructed by turning over the curved surface section, and mostly using sliding form construction on the inclined flat section. The construction process is complex, the cycle is long, and the quality is difficult to guarantee. At present, there is no suitable S-shaped overflow dam surface forming equipment. [0003] Middle and high dams have a large discharge velocity, generally greater...
