Detailed Description

The utility model provides a two lining platform truck concrete pouring chutes in tunnel for pour into tunnel secondary lining concrete.

As shown in fig. 1 and 2, the utility model discloses a two lining platform truck concrete pouring chutes in tunnel include ejection of compact storehouse 1, top layer walking frame 3, one-level chute 4, second grade chute and the window of pouring 10 that connect in the same time. Wherein, the first-stage chute 4 and the second-stage chute are respectively symmetrically arranged at two sides of the discharging bin 1; go out feed bin 1 and be fixed in top layer walking frame 3 center through mount 2, go out the discharge gate of feed bin 1 and the entry end welding of the one-level chute 4 about with. The second grade chute includes I portion 6 of second grade chute and II portions 7 of second grade chute, the export section internal diameter adaptation of one-level chute 4 is in the entry external diameter of I portion 6 of second grade chute, therefore, the exit end of one-level chute 4 passes through connecting sleeve 5 and connects in the entry end of I portion 6 of second grade chute, there are how many kinds of windows 10 of pouring from the second grade chute lower part then prepare the connecting sleeve 5 that corresponds the type, each 1 drilling in connecting sleeve 5's both ends, and adopt bolt 8 and nut 9 to connect, in fact, connecting sleeve 5 should have wear-resisting, characteristics such as high temperature resistant and corrosion-resistant. The export section internal diameter adaptation of I portion 6 of second grade chute in the entry external diameter of II portions 7 of second grade chute, the node of the exit end of I portion 6 of second grade chute and the entry end of II portions 7 of second grade chute all is equipped with the drilling that quantity and interval are the same, the drilling quantity of biggest overlap portion is 4 (every 1), the export pot head of I portion 6 of second grade chute inlays inside the entry end of II portions 7 of second grade chute, thereby control interface section internal diameter male degree is used for adjusting the chute effective length in order to adapt to the different 10 heights of pouring of window of butt joint. When concrete is poured, the overlapped parts are connected through the bolts 8 and the nuts 9, and the other drilled holes are also fixed through the bolts 8 and the nuts 9 so as to prevent the concrete from overflowing. The outlet end of the second-stage chute II part 7 is in bolted connection with the pouring window 10, and a fixing ring is arranged at the contact part so as to prevent the outlet end of the second-stage chute II part 7 from shaking; the effective lengths of the first second-stage chute part 6 and the second-stage chute part 7 are respectively adapted to the die-entering height of the pouring window 10, namely, the retractility is adjusted according to the die-entering height of the pouring window 10.

Specifically, the elongation process in the adjustment of the stretchability is: because the height of the pouring window 10 is different, when the secondary chute moves from the pouring window 10 to the pouring window 10 at the lower end, the overlapped part of the outlet section of the first-stage chute 4 and the inlet section of the first-stage chute 6, the overlapped part of the bolt 8 and the nut 9 of the outlet section of the first-stage chute 6 and the overlapped part of the inlet section of the second-stage chute 7 are removed respectively, then the outlet section length of the first-stage chute 6 is partially drawn out from the first-stage chute 4, the inlet section length of the second-stage chute 7 is partially drawn out from the second-stage chute I6, and then after the position is adjusted, the overlapped part of the outlet section of the first-stage chute 4 and the inlet section of the second-stage chute I6, the overlapped part of the outlet section of the second-stage chute I6 and the overlapped part of the inlet section of the second-stage chute II 7 are fixed by the bolt 8 and the nut 9. Likewise, the shortening process in the scalability adjustment is: because the height of the pouring window 10 is different, when the second-stage chute moves from the pouring window 10 to the pouring window 10 at the upper end, the overlapped part of the outlet section of the first-stage chute 4 and the inlet section of the first second-stage chute 6, the overlapped part of the outlet section of the first second-stage chute 6 and the overlapped part of the inlet section of the second-stage chute 7 and the bolt 8 and the nut 9 are removed respectively, the outlet section of the first-stage chute 4 is retracted into the first second-stage chute 6 from the outside and the inside, the outlet section of the first second-stage chute 6 is retracted into the second-stage chute 7 from the outside and the inside, after the position is adjusted, the overlapped part of the outlet section of the first-stage chute 4 and the inlet section of the first second-stage chute 6, the overlapped part of the outlet section of the first second-stage chute 6 and the overlapped part of the inlet section of the second-stage chute 7.

The utility model discloses an in the embodiment, go out feed bin 1 and be hourglass hopper-shaped, go up port and lower port and be the rectangle, and go up the port sectional area and be greater than the port sectional area down so that the pan feeding, its lower port welding one-level chute 4.

In the embodiment of the utility model, the one-level chute 4 and the second grade chute all adopt steel material.

The principle of the utility model is that: when the automatic feeding device works, the pump truck lifts concrete and sends the concrete into the discharging bin 1, the pressure in the discharging bin 1 is continuously increased along with the continuous entering of concrete materials, and the high and stable feeding speed can be ensured under the action of pressure and gravity; the material gets into one-level chute 4 earlier, and rethread connecting sleeve 5 gets into I portion 6 of second grade chute, gets into II portions 7 of second grade chute along a straight line of second grade chute, and finally, the concrete material is through pouring window 10 income mould.
