[0002] During the construction of large-scale facilities such as bridges and tunnels, concrete is quite heavy. Generally, the mixed concrete needs to be transferred from the on-site mixer discharge port to the mold, transport vehicle, or designated construction location. Because the amount of concrete output from the mixer discharge port is large, it cannot be output in small, precise quantities. When precise control of the required concrete weight is needed, the mixer discharge port cannot accurately control the output weight of the concrete, causing inconvenience to the construction. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a cantilever concrete receiving device and operating method to solve the problem that traditional large concrete mixers cannot quantitatively deliver materials.

A concrete receiving mechanism includes a rotating sub-mechanism, a cantilever steering telescopic sub-mechanism, and a receiving hopper. The rotating sub-mechanism is axially slidably sleeved on one side of a fixed frame below the mixer. One end of the cantilever steering telescopic sub-mechanism is hinged to the rotating sub-mechanism, and the other end extends downward toward the discharge port of the receiving pipe and is connected to a receiving hopper for receiving the concrete output from the receiving pipe.

[0006] Furthermore, the rotating sub-mechanism includes a rotating drum, a first drive motor, a first gear ring, and a first drive gear. The rotating drum is slidably sleeved on a column on one side of the fixed frame. The first gear ring is sleeved on the outer circumference of the rotating drum.

[0007] Furthermore, the cantilever steering telescopic submechanism includes a lateral telescopic component, a longitudinal steering component, and a deflection telescopic component. One end of the lateral telescopic component is hinged to the outer periphery of the rotating drum, and the other end extends to the lateral side of the hopper away from the rotating drum. The longitudinal steering component includes a crank arm, a vertical shaft, and a crank arm drive component that drives the vertical shaft to rotate. The vertical shaft is hinged to the extended end of the lateral telescopic component. One end of the crank arm is fixed to the vertical shaft, and the other end of the crank arm is connected to the receiving hopper. The crank arm drive component is disposed on the lateral telescopic component and is used to drive the vertical shaft to cause the crank arm to swing horizontally. The two ends of the deflection telescopic component are respectively hinged to the rotating drum and the lateral telescopic component and are used to drive the lateral telescopic component to pitch and deflect. The lateral telescopic component, the longitudinal steering component, and the deflection telescopic component are all electrically connected to the controller.

[0008] Furthermore, the articulated arm drive component includes an articulated arm telescopic assembly, a first rack, and a second drive gear. One end of the articulated arm telescopic assembly is fixed to the lateral telescopic assembly, and the other end is connected to the first rack. The second drive gear is sleeved on the vertical shaft and meshes with the first rack. The articulated arm telescopic assembly is electrically connected to the controller.

[0009] Furthermore, it also includes a cleaning sub-mechanism, which includes a linear sliding assembly, a cleaning telescopic assembly, and a rinsing water pipe.

When the concrete reaches the preset weight, control the receiving pipe to rotate again and stop receiving concrete. Step S3: After receiving the material, control the concrete receiving mechanism to move the receiving hopper above the unloading point and unload the concrete.

[0014] Because the present invention adopts the above technical solution, it has the following advantages and effects: This invention provides a cantilevered concrete receiving device and operating method.

Detailed Implementation

[0018] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings to provide a clearer understanding of the purpose, features, and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative of the essential spirit of the technical solution of the present invention.

[0019] like Figures 1-2 As shown. The present invention provides a cantilevered concrete receiving device, including a concrete discharge mechanism, a concrete receiving mechanism, and a controller 38. The concrete discharge mechanism is installed on the hopper 3 below the mixer 1 and is used to quantitatively discharge a portion of the concrete output from the mixer 1. The concrete receiving mechanism is installed on the fixed frame 2 and located on one side of the outer perimeter of the hopper 3, and is used to receive the concrete output by the concrete discharge mechanism and move the concrete to the unloading position.

[0020] The concrete discharge mechanism includes a receiving pipe 18, which is axially slidably sleeved on the discharge hopper 3 and extends outwards from the discharge hopper 3 at both ends. The receiving pipe 18 is used to axially rotate to receive and discharge concrete from the mixer 1. The end of the receiving pipe 18 extending into the discharge hopper 3 is the receiving port, and the end extending outwards from the discharge hopper 3 is the discharge port 34. The opening directions of the receiving port and the discharge port 34 are opposite along the radial direction of the receiving pipe 18. The concrete receiving mechanism includes a rotating sub-mechanism, a cantilever steering telescopic sub-mechanism, and a receiving hopper 35. The rotating sub-mechanism is slidably mounted on one side of the fixed frame 2 below the mixer 1. One end of the cantilever steering telescopic sub-mechanism is hinged to the rotating sub-mechanism, and the other end extends downward toward the discharge port 34 of the receiving pipe 18. The receiving hopper 35 is connected to the extended end of the cantilever steering telescopic sub-mechanism to receive the concrete output from the receiving pipe 18. The cantilever steering telescopic sub-mechanism is used to drive the receiving hopper 35 to move below the discharge port 34. The controller 38 is used to drive the concrete discharge mechanism and the concrete receiving mechanism to move and realize the quantitative transportation of concrete from the mixer 1 to the unloading position without passing through the concrete discharge hopper 3, which facilitates the quantitative delivery of concrete.

[0021] Specifically, the controller 38 and the mixer 1 are fixed above the mounting frame 2, and the hopper 3 is connected below the mixer 1 and located inside the mounting frame 2. The mounting frame 2 is supported by columns 4 on all four sides. When material needs to be received, the controller 38 controls the material receiving pipe 18 to rotate so that the receiving port of the material receiving pipe 18 is opposite to the discharge port of the mixer 1. The concrete is delivered to the receiving hopper 35 through the receiving port. When the weight of the concrete in the receiving hopper 35 reaches the preset requirement, the controller 38 controls the material receiving pipe 18 to rotate 180° again so that the receiving port is directly below and no longer receives concrete. The controller then controls the concrete receiving mechanism to move the receiving hopper 35 to the discharge position for unloading.

[0022] Furthermore, the concrete discharge mechanism also includes a fixed plate 7, a third drive motor 10, a second gear ring 16, and a fourth drive gear 40. The fixed plate 7 is located on the side of the discharge hopper 3. The material receiving pipe 18 is axially slidably sleeved on the fixed plate 7 and passes through the discharge hopper 3. The second gear ring 16 is sleeved on the outer periphery of one end of the material receiving pipe 18 extending out of the fixed plate 7. The third drive motor 10 is located on the fixed plate 7 and the output end is sleeved with the fourth drive gear 40 that meshes with the second gear ring 16. The third drive motor 10 is electrically connected to the controller 38 and is controlled by the controller 38 to start and stop.

[0023] Specifically, a vertical fixing plate 7 is welded and fixed to the side of the feeding hopper 3. A material receiving tube 18 is mounted on the center of the fixing plate 7 through a second bearing 39. The receiving port of the material receiving tube 18 is a slanted fan-shaped funnel larger than a semicircle to expand the receiving area. A second gear ring 16 is fixed on the outer circle of the material receiving tube 18. A third drive motor 10 is also installed on the fixing plate 7. The third drive motor 10 drives the material receiving tube 18 to rotate, changing the direction of the receiving port 34.

[0024] Furthermore, the rotating sub-mechanism includes a rotating drum 5, a first drive motor 8, a first gear ring 15, and a first drive gear 11. The rotating drum 5 is axially slidably sleeved on a column 4 on one side of the fixed frame 2. The first gear ring 15 is sleeved on the outer periphery of the rotating drum 5. The first drive motor 8 is mounted on the column 4. The first drive gear 11 is sleeved on the output end of the first drive motor 8 and meshes with the outer periphery of the first gear ring 15. One end of the cantilever steering telescopic sub-mechanism is hinged to the outer periphery of the rotating drum 5. The first drive motor 8 is electrically connected to the controller 38.

[0025] Specifically, a pair of first bearings 6 are fitted on the column 4 with relative spacing between them. The two ends of the rotating drum 5 are fitted on the outer circumference of the first bearings 6. The first drive motor 8 is fixed on the column 4 at the upper end of the rotating drum 5. The first drive motor 8 drives the first drive gear 11 to mesh with the first gear ring 15, thereby driving the rotating drum 5 to rotate and thus realizing the cantilever steering telescopic sub-mechanism to drive the receiving hopper 35 to swing horizontally.

[0026] Furthermore, the cantilever steering telescopic submechanism includes a lateral telescopic component, a longitudinal steering component, and a deflection telescopic component. One end of the lateral telescopic component is hinged to the outer periphery of the rotating drum 5, and the other end of the lateral telescopic component extends to the lateral side of the hopper 3 away from the rotating drum 5. The longitudinal steering component includes a crank arm 19, a vertical shaft 33, and a crank arm drive component that drives the vertical shaft 33 to rotate. The vertical shaft 33 is hinged to the extension end of the lateral telescopic component. One end of the crank arm 19 is fixed to the vertical shaft 33, and the other end is connected to the receiving hopper 35. The crank arm drive component is set on the lateral telescopic component and is used to drive the vertical shaft 33 to drive the crank arm 19 to swing horizontally. The two ends of the deflection telescopic component are respectively connected to the rotating drum 5 and the lateral telescopic component and are used to drive the lateral telescopic component to pitch and deflect, so as to realize the vertical movement of the receiving hopper 35.

[0027] Specifically, the fixed end of the deflection telescopic assembly is hinged to the lower outer periphery of the rotating drum 5, and the fixed end of the lateral telescopic assembly is hinged to the upper outer periphery of the rotating drum 5, located below the first gear ring 15. To lengthen the telescopic end of the lateral telescopic assembly, a connecting rod 20 is connected to the telescopic end of the lateral telescopic assembly. One end of the connecting rod 20 is connected to a hinge frame 37. The front end of the hinge frame 37 is internally hinged to a crank arm 19. One end of the crank arm 19 is fixed to the vertical shaft 33, and the other end of the crank arm 19 is connected to the receiving hopper 35. Both ends of the vertical shaft 33 pass through the hinge frame 37 and are hinged to the upper and lower end faces of the hinge frame 37. A crank arm drive component is fixed on the connecting rod 20. The crank arm drive component drives the crank arm 19 to swing and move in the horizontal longitudinal direction. At the same time, the lateral telescopic assembly moves in the horizontal lateral direction to realize the horizontal and longitudinal movement of the receiving hopper 35. Since the hopper is conical, the articulated arm 19 can swing and move in the horizontal longitudinal direction along the hinged frame 37, and the horizontal telescopic component can extend and retract horizontally to achieve the connection of the hopper 35 around the hopper 3 and then be located below the discharge port 34.

[0028] Furthermore, the articulated arm drive component includes an articulated arm telescopic assembly 24, a first rack 13, and a second drive gear 12. One end of the articulated arm telescopic assembly 24 is fixed to the lateral telescopic assembly, and the other end of the articulated arm telescopic assembly 24 is connected to the first rack 13. The second drive gear 12 is sleeved on the vertical shaft 33 and meshes with the first rack 13. The articulated arm telescopic assembly 24 is electrically connected to the controller 38.

[0029] Specifically, the extension and retraction directions of the articulated arm telescopic assembly and the lateral telescopic assembly are the same. The fixed end of the articulated arm telescopic assembly is fixed on the connecting rod 20. The extension and retraction end of the articulated arm telescopic assembly 24 is connected to the first rack 13. The linear reciprocating movement is converted into the rotation of the second drive gear 12 by the articulated arm telescopic assembly 24, thereby realizing the forward and reverse rotation of the vertical shaft 33 and controlling the swing of the articulated arm 19.

[0030] Furthermore, the lateral telescopic assembly includes a cantilever 21, a telescopic rod 22, and a telescopic cylinder 23. One end of the cantilever 21 is hinged to the outer periphery of the rotating drum 5, and the telescopic rod 22 is slidably sleeved on the inner periphery of the other end of the cantilever 21. The fixed end of the telescopic cylinder 23 is hinged to the end of the cantilever 21 near the rotating drum 5, and the telescopic end of the telescopic cylinder 23 is hinged to one end of the telescopic rod 22. The other end of the telescopic rod 22 is connected to the hinge frame 37 and the crank arm drive assembly 24 through the connecting rod 20.

[0031] Furthermore, to protect the hydraulic lines, wires, etc. that move with the lateral telescopic assembly, a drag chain 31 is provided on the lateral telescopic assembly. One end of the drag chain 31 is fixed to the cantilever 21, and the other end is fixed to the front end of the telescopic rod 22.

[0032] As a preferred embodiment, the lateral telescopic assembly can also be a telescopic cylinder or a telescopic hydraulic cylinder. In this case, the connecting rod 20 connects to the telescopic end of the lateral telescopic assembly, the fixed end of the lateral telescopic assembly is hinged to the outer cylinder 5, and both ends of the deflection telescopic assembly 25 are respectively hinged to the outer cylinder 5 and the outer periphery of one fixed end of the lateral telescopic assembly. The cable chain 31 is fixed to both ends of the lateral telescopic assembly.

[0033] Furthermore, to facilitate the cleaning of the material collection pipe 18, the concrete material collection mechanism is also equipped with a cleaning sub-mechanism for cleaning the material collection pipe 18. The cleaning sub-mechanism includes a linear sliding component, a cleaning telescopic component 27, and a flushing water pipe 28. One end of the linear sliding component is hinged above the fixed plate 7. The two ends of the cleaning telescopic component 27 are respectively hinged to the fixed plate 7 and the linear sliding component, which is used to drive the linear sliding component to swing. The flushing water pipe 28 is slidably connected to the linear sliding component and moves along the axial direction of the linear sliding component. One end of the flushing water pipe 28 is used to extend into the material collection pipe 18 to spray water and flush the concrete adhering to the inner wall of the material collection pipe 18. The cleaning telescopic component 27 is electrically connected to the controller 38.

[0034] Specifically, the top of the fixed plate 7 is hinged to the fixed end of the cleaning telescopic assembly 27, and the telescopic end of the cleaning telescopic assembly 27 is hinged to the linear sliding assembly. By adjusting the angle of the linear sliding assembly through the cleaning telescopic assembly 27, the cleaning telescopic assembly drives the linear sliding assembly to swing so that the axial direction of the flushing water pipe 28 is aligned with that of the material taking pipe 18, which facilitates the flushing water pipe 28 to enter the material taking pipe 18.

[0035] Furthermore, the linear sliding assembly includes a flushing slide rod 26, a sliding block 36, a second rack 14, a second drive motor 9, and a third drive gear 17. One end of the flushing slide rod 26 is hinged above the center of the fixed plate 7, and the other end of the flushing slide rod 26 is a free end. The second rack 14 is axially arranged on the upper side of the flushing slide rod 26, and the sliding block 36 is nested on the lower side of the flushing slide rod 26. The second drive motor 9 is fixed to the rear side of the sliding block 36. The output end of the second drive motor 9 is fitted with the third drive gear 17, which meshes with the second rack 14. The second drive motor 9 is electrically connected to the controller 38. The flushing water pipe 28 has a U-shaped structure, with one end connected to the sliding block 36 and the other end extending towards the material receiving pipe 18. The second drive motor 9 drives the third drive gear 17 to move axially along the second rack 14, causing the flushing water pipe 28 to axially enter and exit the material receiving pipe 18.

[0036] Furthermore, to improve the cleaning effect of the material intake pipe 18, a rotating flushing head 29 is provided at one end of the flushing water pipe 28 that extends into the material intake pipe 18. The rotating flushing head 29 is provided with multiple nozzles arranged in a circumferential array at an angle of 45° to 55° to its axis and installed at an angle. Under the action of water pressure, a rotational torque can be generated to make the rotating flushing head 29 rotate, forming a rotating sweeping water flow.

[0037] Furthermore, a baffle plate 30 is slidably embedded at the bottom of the receiving hopper 35. When the receiving hopper 35 reaches the unloading position, unloading is achieved by pulling out the baffle plate 30. A sensor 32 for detecting the weight of concrete in the receiving hopper 35 is installed on the fixed plate 7. The sensor 32 is vertically aligned with the inner cavity of the receiving hopper 35 and is electrically connected to the controller 38. The sensor 32 sends a signal to the controller 38 when the concrete reaches a preset weight, and the controller 38 controls the third drive motor 10 to drive the material picking tube 18 to rotate, stopping the material picking. The sensor 32 is a distance detection sensor, which sends a signal after calculating the distance from the top of the concrete in the receiving hopper 35.

[0038] Furthermore, as a preferred embodiment, the telescopic cylinder 23, the crank arm drive assembly 24, the deflection telescopic assembly 25, and the cleaning telescopic assembly 27 are all telescopic air cylinders or telescopic hydraulic cylinders.

[0039] Furthermore, the controller 38 is a PLC controller. The controller 38 is electrically connected to components such as the telescopic cylinder 23, the crank arm drive assembly 24, the deflection telescopic assembly 25, the cleaning telescopic assembly 27, the first drive motor 8, the second drive motor 9, the third drive motor 10, and the sensor 32. The controller 38 can control the orderly action of each component through the program and issue instructions according to the preset program to coordinate the automated operation of the entire device.

[0040] The present invention also provides an operation method based on a cantilevered concrete receiving device, comprising the following steps: Step S1, Material Receiving Preparation: Start the device via controller 38 to control the movement of the concrete material receiving mechanism to move the receiving hopper 35 and position it to the predetermined receiving position below the discharge port 34.

[0041] Specifically, the deflection telescopic component 25 adjusts the cantilever 21 to the receiving level, and the telescopic cylinder 23 and the crank arm drive component 24 move to move the receiving hopper 35 to the predetermined receiving position below the discharge port 34.

[0042] Step S2, receiving: After controlling the concrete discharge mechanism to rotate the receiving pipe 18, it receives the concrete output from the mixer and flows into the receiving hopper 35 through the discharge port 34. When the concrete reaches the preset weight, the receiving pipe 18 is controlled to rotate again to stop receiving concrete.

[0043] Specifically, the third drive motor 10 in the concrete discharge mechanism is controlled to drive the material receiving pipe 18 to rotate 180° (the material receiving port of the material receiving pipe 18 is pre-positioned below the material receiving pipe), so that the direction of the material receiving port is aligned with the discharge port of the mixer, and the direction of the discharge port 34 of the material receiving pipe 18 is aligned with the receiving hopper 35. When the mixer 1 discharges material, the concrete enters the material receiving pipe 18 through the material receiving port and flows into the receiving hopper 35 from the discharge port 34. When the sensor 32 detects that the weight of the concrete in the receiving hopper 35 has reached the preset weight, it sends a signal to the controller 38. The controller 38 controls the third drive motor 10 to rotate 180° again, so that the material receiving port of the material receiving pipe 18 rotates downward and the discharge port 34 rotates upward, stopping the material receiving.

[0044] Step S3, Transfer: After receiving the material, control the concrete receiving mechanism to move the receiving hopper 35 above the unloading point, and release the concrete through the receiving hopper 35.

[0045] Specifically, the controller 38 controls the crank arm drive assembly 24 to drive the crank arm 19 to rotate in the same axial direction as the cantilever 21. The telescopic cylinder 23 drives the crank arm 19 to telescopically move. The deflection telescopic assembly 25 drives the cantilever 21 and the crank arm 19 to deflect downward. The telescopic cylinder 23, the crank arm drive assembly 24 and the deflection telescopic assembly 25 coordinate their actions to move the receiving hopper 35 to the unloading position below the fixed frame 2.

[0046] Step S4, unloading: After the receiving hopper 35 reaches the unloading point, open the baffle plate 30 at the bottom of the receiving hopper 35 to unload the concrete. After closing the baffle plate 30, repeat the material collection process.

[0047] Step S5, cleaning the material taking tube: When the material taking tube 18 needs to be cleaned after multiple material taking, the cleaning telescopic component 27 of the control cleaning sub-mechanism moves the flushing water pipe 28 to be aligned with the axial direction of the material taking tube 18, and then starts through the second drive motor 9 to move the flushing water pipe 28 along the axial direction of the material taking tube 18 to flush the inner cavity of the material taking tube 18.
