Abstract
Description
Technical Field
[0001] The utility model relates to tunnel construction equipment, in particular to a filling layer concrete finishing device. Background Art
[0002] In the construction of the tunnel invert filling layer, the surface forming requirements of the filling concrete are high, and the demand for filling and plastering equipment is becoming more and more widespread. In the existing tunnel solution, the filling and plastering device is mainly installed on the invert formwork, and some construction is divided according to the center ditch and the left and right widths are constructed. The filling and plastering device is installed on the invert formwork and relies on the left and right invert formwork for positioning, which is difficult to position, and the walking power is on both sides, which affects the installation and use of the invert formwork. The left and right walking power are not synchronized enough, the plastering device has a high walking failure rate, and the plastering device is limited by space, and the overall rigidity is insufficient and easy to deform. In addition, the center ditch formwork, the invert formwork, the side ditch formwork, etc. will inevitably have position errors during installation, including horizontal position errors and height position errors. The height positions of the formworks on both sides may not be the same, but the original designed height is required to be cast during construction. The plastering part of the existing plastering device is divided into an integral plastering ship or an integral full-length roller, so it cannot meet this requirement. The existing plastering device retreats to the initial position after plastering 12m (the standard length of a construction zone) once, and the plastering part is always in contact with the surface of the already plastered filling layer, which may damage the already plastered filling surface.

[0036] Embodiment 1:
[0037] like Figures 1 to 10 As shown, the filling layer concrete finishing device of this embodiment includes a finishing trolley 1, a finishing assembly 2, and longitudinal guide rails 91 arranged on the left and right sides of the trestle 9 and arranged along the length direction of the trestle 9. The finishing trolley 1 is arranged on the longitudinal guide rails 91, and a first lifting drive member 11 is arranged on the finishing trolley 1. The finishing assembly 2 is connected to the first lifting drive member 11. The longitudinal direction is the excavation direction or the length direction of the tunnel.
[0038] The filling layer concrete finishing device of this embodiment is used during finishing construction. Fig.11 and Fig.12 As shown, the plastering trolley 1 moves along the longitudinal guide rail 91, and the plastering assembly 2 plasters the concrete of the tunnel filling layer. After the first plastering is completed, as shown in FIG. Fig.13 and Fig.14As shown, the first lifting drive member 11 drives the plastering assembly 2 to rise as a whole, and then the plastering trolley 1 returns to the initial position, and the first lifting drive member 11 drives the plastering assembly 2 to descend as a whole, and then the second plastering is performed, and the above steps are repeated to achieve multiple plastering. In the filling layer concrete plastering device of this embodiment, the plastering assembly 2 moves along the longitudinal guide rails 91 on the left and right sides of the trestle 9, the plastering assembly 2 is easy to position, has high walking synchronization, and does not affect the passage of vehicles on the trestle 9; when a single plastering is completed, the plastering assembly 2 rises, and then the plastering trolley 1 returns to the initial position, and the plastering assembly 2 will not contact the surface of the already plastered filling layer, and the plastering effect is good.
[0039] Furthermore, in this embodiment, if Figures 3 to 5 As shown, the plastering assembly 2 includes a first mounting bracket 21, a second mounting bracket 22 and a second lifting drive 23 arranged on the left and right sides of the first mounting bracket 21, and a plastering component 24 arranged on the second mounting bracket 22. The first mounting bracket 21 is connected to the first lifting drive 11, and the first mounting bracket 21 and the second mounting bracket 22 are connected through the second lifting drive 23. The second lifting drives 23 on both sides of the first mounting bracket 21 respectively drive the second mounting bracket 22 on the same side to rise and fall, so as to realize the independent lifting of the plastering components 24 on both sides. When there is a height difference between the templates on both sides of the tunnel, only the height of the plastering assembly 2 on one side can be adjusted, which can adapt to the different height requirements of the templates on both sides or the height installation errors of the templates on both sides, and the structure is simple and reasonable. Among them, the first lifting drive 11 and the second lifting drive 23 can be, for example, a cylinder, an oil cylinder or an electric push rod, etc., which will not be repeated.
[0040] Furthermore, in this embodiment, the plastering component 24 is a plastering roller, and a rotary drive 221 for driving the plastering roller to rotate is provided on the second mounting bracket 22. When plastering, the rotary drive 221 drives the plastering roller to rotate to plaster, and the plastering roller can quickly complete the plastering work of a large area with high plastering efficiency. Among them, the rotary drive 221 can be, for example, a motor or a hydraulic motor, which drives the plastering roller to rotate through a transmission method such as a sprocket material strip.
[0041] Furthermore, in this embodiment, if Figure 7 As shown, the plastering assembly 2 further includes a scraping component 25 disposed on the second mounting bracket 22. By providing the scraping component 25, the scraping component 25 scrapes the concrete after plastering, further improving the plastering effect.
[0042] Furthermore, in this embodiment, the scraping component 25 is a scraping plate. The scraping plate can improve the flatness of the concrete surface and make the concrete surface smoother.
[0043] Furthermore, in this embodiment, a first lifting guide assembly 3 is provided between the plastering trolley 1 and the plastering assembly 2. By providing the first lifting guide assembly 3, it is possible to prevent the plastering component 24 from deflecting when it is lowered alone, thereby affecting the plastering effect. The first lifting guide assembly 3 may be, for example, a guide rod and a guide sleeve, or a guide rail and a slider, a pulley, etc., which will not be described in detail.
[0044] Furthermore, in this embodiment, a second lifting guide assembly 4 is provided between the first mounting bracket 21 and the second mounting bracket 22. By providing the second lifting guide assembly 4, it is possible to prevent the plastering assembly 2 from being offset when the entire assembly is lifted and lowered, thereby affecting the plastering effect. The second lifting guide assembly 4 may be, for example, a guide rod and a guide sleeve, or a guide rail and a slider, a pulley, etc., which will not be described in detail.
[0045] Furthermore, in this embodiment, longitudinal guide rails 91 are provided at the upper and lower parts of the trestle 9, and guide rollers 12 are provided at the upper and lower parts of the plastering trolley 1, and the guide rollers 12 are arranged one by one with the longitudinal guide rails 91. By providing longitudinal guide rails 91 at the upper and lower parts of the trestle 9, and corresponding guide rollers 12 at the upper and lower parts of the plastering trolley 1, the stability of the plastering trolley 1 when moving along the trestle 9 can be ensured, and the operation is more stable.

[0048] In this embodiment, the plastering component 24 includes a vibrating boat and a vibrating driving member 222 connected to the vibrating boat. The vibrating driving member 222 drives the vibrating boat to plaster the surface, and the vibrating boat can effectively transmit vibration to make the concrete surface smooth.
