DETAILED DESCRIPTION

[0017] The present invention will be further explained and illustrated below with reference to the accompanying drawings:

[0018] For example, see Figure 1-Figure 3 A secondary grouting trolley for the construction of a wind turbine foundation comprises an upper frame 1, a lower frame 2 and a lower hopper 9. The lower frame 2 is connected to the upper frame 1 through a connecting rod 3, and legs 4 are provided at both ends of the lower frame 2. Rollers 5 are provided at the bottom of the legs 4. A first displacement plate 7 is slidably connected to the top of the upper frame 1, and a second displacement plate 11 is slidably connected to the top of the lower frame 2. A first discharge pipe 10 is provided between the first displacement plate 7 and the second displacement plate 11, a lower hopper 9 is provided above the first displacement plate 7, a second discharge pipe 12 is provided below the second displacement plate 11, and a valve 13 is provided on the outer wall of the second discharge pipe 12.

[0019] First through holes are respectively provided in the middle of the first displacement plate 7 and the second displacement plate 11 , and a first discharge pipe 10 is provided between the two corresponding first through holes at the upper and lower ends.

[0020] A lower hopper 9 is provided above the first displacement plate 7 , and a third lower hopper 901 is provided at the bottom of the lower hopper 9 . The third lower hopper 901 extends into the first lower hopper 10 .

[0021] Displacement tracks 6 are respectively provided on both sides of the top of the first displacement plate 7 and the second displacement plate 11. The first displacement plate 7 and the second displacement plate 11 are respectively slidably connected to the corresponding displacement tracks 6 through sliders, and tightening bolts 8 are respectively provided on the outer walls of the first displacement plate 7 and the second displacement plate 11.

[0022] There are two first displacement plates 7 and two second displacement plates 11 .

[0023] In the above description, the bottom of the second feeding pipe is located 5 cm above the bottom of the roller.

[0024] In the above description, the length of the third discharge pipe at the bottom of the discharge hopper is 3 cm, and the outer diameter of the third discharge pipe is smaller than the inner diameter of the second discharge pipe.

[0025] In the above description, the third discharge pipe is located at the center of the bottom of the discharge hopper.

[0026] In the above description, the upper frame and the lower frame have the same length.

[0027] Working principle:

[0028] When in use, place the device on one side of the fan foundation, place a lower hopper on the two first displacement plates, and close the valve outside the second lower pipe; adjust the position of the second lower pipe according to the position of the casting joint, and then add grouting liquid into the lower hopper. After the preparation work is done, open the valve, and wait until the grouting liquid on one side overflows the gap on the other side, then close the valve.

[0029] In the above description, the grouting gaps of the fan cap foundation are two circles, inner and outer. When pouring, the pouring is completed when the grouting liquid on one side fills the grouting gap on the other side.

[0030] By using this device, both ends of the annular grouting joint can be poured simultaneously, which improves work efficiency and the workers no longer need to repeatedly and uninterruptedly pour with a small paddle.

[0031] During the pouring process, the device can also make circular movements along the annular grouting joint to adjust the grouting position.

[0032] The utility model can freely adjust the positions of the two displacement plates according to the position of the material seam. At the same time, by arranging a second discharge pipe below the second displacement plate and arranging a valve on the outer wall of the second discharge pipe, accurate feeding can be achieved, and the valve can be closed in time according to the discharge situation, thereby improving work efficiency and avoiding overflow of grouting liquid. It is easy to use, simple to operate, and easy to promote.
