[0028] See also Figures 1 to 6 , the present invention provides a technical solution:

[0029] Embodiment 1: A concrete spreading vehicle for fully spreading concrete comprises a frame 2 and a mixing tank 1. The frame 2 is provided with a mixing tank 1 which is rotationally controlled by a rotating support 5. One end of the mixing tank 1 is provided with a discharger 16 for discharging the internal concrete. The lower end of the frame 2 is provided with four sets of tires 11 located on both sides of the mixing tank 1. The tires 11 are rotatably mounted on transverse extension arms 4. The transverse extension arms 4 are telescopically plugged and mounted on the frame 2. Telescopically mounted longitudinal support arms 6 are provided at the head and tail ends of the frame 2. Support members 9 are provided at the ends of the longitudinal support arms 6. The lower end of the frame 2 is provided with a track 7 driven by a lifting assembly. Positioning members 8 cooperating with the support members 9 for positioning are provided on the track 7. The frame 2 is provided with multiple sets of driving members 3, and the multiple sets of driving members 3 are all hydraulic telescopic members. The driving member 3 is used to control the telescopic drive of the lateral extension arm 4 and the longitudinal support arm 6. A hydraulic system 15 for controlling the driving member 3 is provided on the frame 2. The lifting component is provided as a lifting driving rod 31, and the lifting driving rod 31 is controlled by the hydraulic system 15. One end of the lifting driving rod 31 is fixed on the frame 2, and the other end of the lifting driving rod 31 is connected to the track 7. The track 7 is located at the lower end of the support member 9. A mounting seat 10 is provided at the outer end of the lateral extension arm 4, and a rotating seat 12 is provided on the mounting seat 10. The tire 11 is rotatably mounted on the rotating seat 12. The rotating seat 12 controls the tilt angle through a motor, and allows the tire 11 to be tilted and pressed on the arc inner wall of the tunnel segment 13. A control room 14 for controlling the drive of the tire 11 and the hydraulic system 15 is provided on the frame 2.

[0030] By providing a transverse extension arm 4 and a longitudinal support arm 6 which can be telescopically arranged along the vehicle frame 2, the driving angle switching of the tire 11 is realized. On a flat ground, the tire 11 is normally pressed on the ground for driving transportation. However, when it moves into the tunnel segment 13, the lifting drive rod 31 is used to drive the track 7 to descend and press it on the inner wall of the tunnel segment 13. At this time, the longitudinal support arm 6 is used to drive the support member 9 to descend. The positioning member 8 and the support member 9 cooperate to achieve the purpose of accurately positioning and stably supporting the vehicle frame 2 (such as Figure 3 Then, by extending the lateral extension arm 4 and adjusting the angle of the rotating seat 12, the driving tire 11 is tilted to fit the inner wall of the tunnel segment 13 (as shown in FIG. Figure 4 As shown), the driven transport adapted to the inner wall of the arc is realized.

[0031] A fabric box 18 is provided at the lower end of the discharger 16, and elastic folding plates 26 are elastically installed on the front and rear sides of the fabric box 18. A pair of adjusting cone blocks 19 driven by a lifting assembly are provided in the fabric box 18, and the inclined cone surface of the adjusting cone block 19 is pressed on one side of the elastic folding plate 26.

[0032] During transportation, the concrete in the mixing tank 1 is discharged by spiral stirring and falls on the discharger 16. The concrete falls along the discharger 16 into the distribution box 18. The height of the cone block 19 is controlled and adjusted by the lifting component to achieve the squeezing of the elastic folding plate 26. The extension and compression of the elastic folding plate 26 are used to control the width of the material discharge from the distribution box 18, so as to achieve the adaptive adjustment of the distribution width.

[0033] Embodiment 2: Based on Embodiment 1, the discharger 16 is rotatably mounted on the frame 2, and an adjusting rod 17 for controlling the inclination angle of the discharger 16 is provided on the frame 2. One end of the discharger 16 is located at the lower end of the discharge port of the mixing tank 1, and the lower end of the other end of the discharger 16 is directly opposite to the upper end port of the distribution box 18. The upper end of the discharge box 18 is provided with a baffle 21 extending to the top of the lower end port of the discharger 16.

[0034] The baffle 21 is provided to prevent concrete from splashing, and the adjusting rod 17 is used to control the discharging angle of the discharging device 16 to ensure that the concrete accurately falls into the upper end port of the material distribution box 18.

[0035] A diversion cavity 22 is provided at the lower end of the material distribution box 18, and a guide block 23 is fixedly provided at the middle position of the lower end of the diversion cavity 22. The middle of the upper end of the guide block 23 is convex, and both sides extend downward at an angle. A plurality of through holes 24 are vertically provided on the guide block 23. A gap is left between the two sides of the guide block 23 and the inner wall of the diversion cavity 22. An elastic folding plate 26 is installed in the gap. One side of the elastic folding plate 26 is fixed on the guide block 23, and an extrusion side plate 27 is provided on the other side of the elastic folding plate 26. Slide grooves are provided on the side walls at both ends of the diversion cavity 22, and an adjusting cone block 19 is lifted and installed in a pair of slide grooves, and the inclined surface of the adjusting cone block 19 is pressed on the extrusion side plate 27.

[0036] By adjusting the lifting and lowering of the cone block 19, its inclined surface can realize the extrusion adjustment of the extrusion side plate 27. After the extrusion side plate 27 is compressed, it will cause the elastic folding plate 26 to contract, so that the width of the cloth in the inner cavity of the cloth box 18 is limited, thereby achieving the purpose of adjusting the cloth width.

[0037] Embodiment 3: Based on Embodiment 2, a positioning rod 30 is vertically arranged in the slideway, a positioning hole 29 is penetrated on the adjusting cone block 19 and is slidably plugged with the positioning rod 30, a spring 28 is pressed between the upper end of the adjusting cone block 19 and the inner wall of the upper end of the slideway, and the spring 28 is sleeved on the positioning rod 30. The lower ends of a pair of adjusting cone blocks 19 are fixedly connected by a connecting rod 25, and the connecting rod 25 is connected to the lifting drive rod 31 through the lifting rod 20.

[0038] By setting the cooperation of the connecting rod 25 and the lifting rod 20, the adjusting cone block 19 is integrally connected to the lifting drive rod 31, and the lifting drive rod 31 is used to adjust the width of the cloth laying. The lower end of the cloth box 18 is located at the upper end of the track 7, and the adjustment lifting height of the adjusting cone block 19 is much smaller than the height of the track 7 from the tunnel segment 13 or the ground. Therefore, the lifting and lowering of the track 7 caused by the lifting and lowering drive of the lifting drive rod 31 will not affect the drive of the tire 11.

[0039] By providing the positioning hole 29 and the positioning rod 30, the cone block 19 can be adjusted to be stably raised and lowered, thereby avoiding material leakage caused by deviation.

[0040] A concrete placing method implemented by a concrete placing vehicle for full concrete laying, the concrete placing method comprising the following steps:

[0041] Step 1: For different material laying construction environments, the lateral extension arm 4 and the longitudinal support arm 6 are used to adjust the angle and position of the tire 11 so that the tire 11 is adapted to the construction site for moving the material;

[0042] Step 2: According to the width of the fabric construction, the height of the adjusting cone block 19 is adjusted, thereby adjusting the width of the elastic folding plate 26, so that the blanking width of the fabric box 18 is adapted to the width of the fabric construction.
