Description

Technical Field

[0001] This invention relates to the field of concrete placing trucks and concrete placement construction technology, specifically to a concrete placing truck and a concrete placement method for fully laying concrete. Background Technology

[0002] During the transportation and use of concrete, concrete placing trucks are usually used. Because they are equipped with continuously rotating mixing tanks, the concrete can be kept fluid and prevented from solidifying during transportation.

[0003] However, existing concrete placing trucks are all based on common trailers or flatbed trucks with fixed spans. Therefore, the transportation location is limited by the environment. After being transported to the construction site, additional vehicles are needed for transportation. For example, when pouring concrete in a tunnel, the vehicle's tires cannot travel on a curved surface, and the width of the concrete placement cannot be adjusted during the concrete placement process. Summary of the Invention

[0004] The purpose of this invention is to provide a concrete placing vehicle and a concrete placing method for fully laying concrete, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

One end of the mixing tank is equipped with a discharge device for discharging the internal concrete. Four sets of tires are located on both sides of the mixing tank at the lower end of the frame. The tires are rotatably mounted on lateral extension arms, which are telescopically connected to the frame. Telescopically mounted longitudinal support arms are located at both ends of the frame, and support members are provided at the ends of the longitudinal support arms. A track driven by a lifting assembly is provided at the lower end of the frame. Positioning members that cooperate with the support members are provided on the track. A placing box is located at the lower end of the discharge device. Elastic folding plates are elastically mounted on the front and rear sides of the placing box. A pair of adjusting cones driven by the lifting assembly are provided in the placing box, and the inclined conical surfaces of the adjusting cones press against one side of the elastic folding plates.

[0007] Preferably, the frame is provided with multiple sets of driving components, all of which are hydraulic telescopic components. The driving components are used to control the telescopic drive of the lateral extension arm and the longitudinal support arm, and the frame is provided with a hydraulic system for controlling the driving components.

[0008] Preferably, the lifting assembly is configured as a lifting drive rod, which is controlled by a hydraulic system. One end of the lifting drive rod is fixed to the frame, and the other end is connected to a track located at the lower end of the support.

The tire is rotatably mounted on the rotating seat. The rotating seat is tilted at an angle controlled by a motor, so that the tire can be tilted and pressed against the inner arc of the tunnel segment.

[0010] Preferably, the chassis is equipped with a control room for controlling the tire drive and hydraulic system.

[0011] Preferably, the discharge device is rotatably mounted on the frame, and the frame is provided with an adjusting rod to control the tilt angle of the discharge device. One end of the discharge device is located at the lower end of the discharge port of the mixing tank, and the lower end of the other end of the discharge device is directly opposite the upper port of the material distribution box. The upper end of the material distribution box is provided with a baffle extending to the upper end of the lower port of the discharge device.

[0012] Preferably, the lower end of the fabric box is provided with a diversion cavity, and a guide block is fixedly provided at the middle position of the lower end of the diversion cavity. The upper end of the guide block is raised in the middle and extends downward at an angle on both sides. Multiple sets of through holes are vertically provided on the guide block. A gap is left between the two sides of the guide block and the inner wall of the diversion cavity, and the elastic folding plate is installed in the gap.

[0013] Preferably, one side of the elastic folding plate is fixed to the guide block, and the other side of the elastic folding plate is provided with a squeezing side plate. Slide grooves are provided on both ends of the sidewalls of the diversion cavity. Adjusting cones are installed in each pair of slide grooves, and the inclined surfaces of the adjusting cones are pressed against the squeezing side plates.

[0014] Preferably, a positioning rod is vertically arranged in the chute, and a positioning hole is provided through the adjusting cone to slide and engage with the positioning rod.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 6 The present invention provides a technical solution:

[0029] Example 1: A concrete placing truck for full concrete placement includes a frame 2 and a mixing tank 1. The mixing tank 1, which is rotated and controlled by a rotating support 5, is mounted on the frame 2. A discharge device 16 for discharging the concrete is provided at one end of the mixing tank 1. Four sets of tires 11 are located on both sides of the mixing tank 1 at the lower end of the frame 2. The tires 11 are rotatably mounted on a transverse extension arm 4, which is telescopically connected to the frame 2. Longitudinal support arms 6 are telescopically mounted at both ends of the frame 2. Support members 9 are provided at the ends of the longitudinal support arms 6. A track 7 driven by a lifting component is provided at the lower end of the frame 2. Positioning members 8 that cooperate with the support members 9 are provided on the track 7. Multiple sets of driving components 3 are provided on the frame 2, all of which are hydraulic telescopic components. The drive component 3 is used to control the extension and retraction of the lateral extension arm 4 and the longitudinal support arm 6. The frame 2 is equipped with a hydraulic system 15 to control the drive component 3. The lifting component is set as a lifting drive rod 31, which is controlled by the hydraulic system 15. One end of the lifting drive rod 31 is fixed to the frame 2, and the other end of the lifting drive rod 31 is connected to the rail 7. The rail 7 is located at the lower end of the support component 9. The outer end of the lateral extension arm 4 is equipped with a mounting seat 10, 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 is tilted by a motor, so that the tire 11 can tilt and press against the inner arc of the tunnel segment 13. The frame 2 is equipped with a control room 14 to control the tire 11 drive and the hydraulic system 15.

[0030] By setting a lateral extension arm 4 and a longitudinal support arm 6 that are telescopically mounted along the frame 2, the driving angle of the tire 11 can be switched. On flat ground, the tire 11 is normally pressed against the ground for driving and transportation. However, when it moves into the tunnel segment 13, the lifting drive rod 31 drives the track 7 to descend and press against the inner wall of the tunnel segment 13. At this time, the longitudinal support arm 6 drives the support member 9 to descend. With the cooperation of the positioning member 8 and the support member 9, the purpose of precise positioning and stable support of the frame 2 is achieved (e.g., Figure 3 (As shown), then by utilizing the extension of the lateral extension arm 4 and the angle adjustment of the rotating seat 12, the tire 11 is driven to tilt and conform to the inner wall of the tunnel segment 13 (as shown). Figure 4 As shown in the figure, this enables drive transportation that adapts to the inner wall of the arc.

[0031] The lower end of the feeder 16 is provided with a material box 18. Elastic folding plates 26 are elastically installed on the front and rear sides of the material box 18. A pair of adjusting cones 19 driven by the lifting component are provided in the material box 18. The inclined cone surface of the adjusting cone 19 is pressed against one side of the elastic folding plate 26.

[0032] During transportation, the concrete in the mixing tank 1 is discharged by the spiral agitator and falls onto the discharge device 16. The concrete falls down the discharge device 16 into the material distribution box 18. The height of the adjusting cone 19 is controlled by the lifting component, thereby compressing the elastic folding plate 26. The width of the material distribution box 18 is controlled by the extension and compression of the elastic folding plate 26, thereby achieving the adaptation and adjustment of the material distribution width.

[0033] Example 2: Based on Example 1, the discharge device 16 is rotatably mounted on the frame 2. The frame 2 is provided with an adjusting rod 17 to control the tilt angle of the discharge device 16. One end of the discharge device 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 discharge device 16 is directly opposite the upper end port of the material distribution box 18. The upper end of the material distribution box 18 is provided with a baffle 21 extending to the upper end port of the discharge device 16.

[0034] By setting baffle 21 to prevent concrete from splashing, and by using adjusting rod 17 to control the discharge angle of discharge device 16, it is ensured that it falls accurately into the upper port of distribution box 18.

[0035] The lower end of the fabric box 18 is provided with a diversion cavity 22. A guide block 23 is fixedly provided at the middle position of the lower end of the diversion cavity 22. The upper end of the guide block 23 is raised in the middle and extends downward at an angle on both sides. Multiple sets 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. A pressing side plate 27 is provided on the other side of the elastic folding plate 26. Slide grooves are provided on both ends of the diversion cavity 22. An adjusting cone 19 is installed in each of the two slide grooves. The inclined surface of the adjusting cone 19 is pressed against the pressing side plate 27.

[0036] By adjusting the lifting and lowering of the cone block 19, its inclined surface can be used to press and adjust the extrusion side plate 27. When the extrusion side plate 27 is pressed, it will cause the elastic folding plate 26 to contract, thereby limiting the width of the fabric in the inner cavity of the fabric box 18, thus achieving the purpose of adjusting the width of the fabric.

[0037] Example 3: Based on Example 2, a positioning rod 30 is vertically installed inside the slide groove. A positioning hole 29 is provided through the adjusting cone 19 to slide and engage with the positioning rod 30. A spring 28 is pressed between the upper end of the adjusting cone 19 and the upper inner wall of the slide groove, and the spring 28 is sleeved on the positioning rod 30. The lower ends of a pair of adjusting cones 19 are fixedly connected by a connecting rod 25, and the connecting rod 25 is connected to the lifting drive rod 31 through a lifting rod 20.

[0038] By setting up the linkage 25 and the lifting rod 20, the adjusting cone 19 is integrally connected to the lifting drive rod 31. The width of the fabric laying is adjusted by using the lifting drive rod 31. The lower end of the fabric box 18 is located at the upper end of the track 7. The adjustment height of the adjusting cone 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 drive rod 31 will not affect the driving of the tire 11.

[0039] By setting the positioning hole 29 and the positioning rod 30 to cooperate, the adjustment cone 19 can be raised and lowered stably, avoiding material leakage caused by deviation.

[0040] A concrete placement method based on a fully deployed concrete placing vehicle, the method comprising the following steps:

[0041] Step 1: For different fabric 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 can be adapted to the construction site for moving the fabric.

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

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
