Description

Technical Field

[0001] A green and environmentally friendly concrete pumping device for construction. This invention belongs to the field of concrete wall construction technology, specifically relating to the field of concrete conveying technology for concrete wall construction. Background Technology

[0002] Concrete pouring is unavoidable in current construction processes. Some pouring areas are high, requiring the use of pumping systems to transport the concrete. Ground pumps are a common method. Before pumping concrete, a detailed inspection of the inside of the pipeline is necessary to prevent concrete adhering to the pipe from affecting the delivery process. Currently, when concrete is observed adhering to the inner wall of the pipeline, the most common method is to use a sledgehammer to tap the pipeline from the outside to separate the adhering concrete from the inside. However, this method easily causes deformation or even cracking of the concrete pipeline, resulting in waste of the pipeline. However, it is impossible for concrete pipes to be completely free of adhering concrete. Therefore, how to efficiently and safely remove the adhering concrete from the inner wall of the pipe has become a problem that needs to be solved. Since the pumping structure has a built-in telescopic structure when transporting concrete, if the telescopic structure can be used to clean the inner wall of the pipe after use, it can effectively prevent concrete from adhering to the inner wall of the pipe. This application proposes a green and environmentally friendly concrete pumping device for construction, which not only meets the needs of pumping concrete, but also assists in cleaning the adhering concrete inside the pipe, thereby avoiding damage to the pipe caused by violent removal. Summary of the Invention

[0004] The technical solution adopted in this invention is as follows:

[0005] A green and environmentally friendly concrete pumping device for construction includes a base plate and an electrical control box. The electrical control box is installed on the surface of the base plate. A concrete transfer chamber is installed on one side of the surface of the base plate, and a conveying and cleaning power structure that provides the necessary power for concrete conveying and cleaning the conveying pipe is installed on the other side of the surface of the base plate. A pipe cleaning bracket is installed on the base plate on the side of the conveying and cleaning power structure to support the pipe to be cleaned. A motor that provides power for the angle changes of the conveying and cleaning power structure and the pipe cleaning bracket is also installed on the surface of the base plate.

[0006] Furthermore, the concrete transfer silo includes a transfer box installed on the surface of the base plate. An adjusting pipe is installed inside the transfer box. A conveying pipe is installed on the side of the transfer box away from the conveying and cleaning power structure at the position corresponding to the adjusting pipe. Two connection ports are opened on the other side of the transfer box at the position corresponding to the adjusting pipe.

[0007] Furthermore, the top end of the adjusting tube is connected to a fixing plate via a connecting column. A rotating shaft is installed on the side of the fixing plate. The rotating shaft passes through and extends to the outer surface of the transfer box and connects to a protrusion. A locking hole is opened inside the protrusion. A locking ball is rolled inside the locking hole. A support plate is installed on the support column of the transfer box. A limit rod is threadedly connected inside the support plate. An electric push rod is installed on the limit rod via a collar. The end of the electric push rod is fixed to the side of the locking ball.

[0008] Furthermore, a feeding pipe is installed at the corresponding connection port on the transfer box, a connecting rod is slidably installed inside the feeding pipe, a piston plate is installed on the side of the connecting rod, a top material head is installed at one end of the connecting rod corresponding to the connection port, and a support plate is installed on the surface of the bottom plate.

[0009] Furthermore, the conveying and cleaning power structure includes a mounting box. Inside the mounting box, corresponding to the position of the feeding pipe, a hydraulic cylinder is installed. Inside the hydraulic cylinder, a second connecting rod is slidably installed. A second piston plate is installed at the end of the second connecting rod away from the first connecting rod. A sleeve is installed at the end of the second connecting rod corresponding to the first connecting rod. A clamp is installed on the first connecting rod that inserts into the sleeve. Both the clamp and the sleeve have threaded holes, and bolts are threaded into the threaded holes. A sealing sleeve is wrapped around the position adjacent to the hydraulic cylinder and the feeding pipe. An oil pump is installed at the top of the mounting box and is connected to the hydraulic cylinder through a pipe. The bottom of the mounting box is mounted on the surface of the base plate through a support shaft. The support shaft is connected to the output shaft of the motor through a sprocket and chain drive structure. A third support plate is installed on the surface of the base plate at the position below the hydraulic cylinder.

[0010] Furthermore, the pigging support includes a mounting plate, the bottom end of which is connected to a base plate via a second support shaft. The second support shaft is connected to a first support shaft via a second sprocket and chain drive structure. The mounting plate is arranged parallel to the hydraulic cylinder and is positioned below the mounting box.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0013] The system not only meets the basic daily needs of concrete pumping, but also allows for the adjustment of the position of the conveying and cleaning power structure and the cleaning support before or after concrete delivery. This places the pipe to be cleaned on the surface of the cleaning support, and then the telescopic structure inside the conveying and cleaning power structure moves inside the conveying pipe to clean the inner wall of the pipe. This replaces the traditional forceful removal method, achieving safe and efficient cleaning of pipe deposits and avoiding damage to the pipe caused by forceful cleaning. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] Example

[0026] like Figures 1 to 9 As shown, a green and environmentally friendly concrete pumping device for construction includes a base plate 1 and an electrical control box 6. The electrical control box 6 is installed on the surface of the base plate 1. A concrete transfer chamber 2 is installed on one side of the surface of the base plate 1. The concrete transfer chamber 2 is mainly used for receiving concrete. A conveying and cleaning power structure 3 is installed on the other side of the surface of the base plate 1 to provide the power required for concrete conveying and cleaning the conveying pipe. The conveying and cleaning power structure 3 provides the power required for concrete conveying and cleaning the inside of the conveying pipe. A cleaning support 4 is installed on the base plate 1 on the side of the conveying and cleaning power structure 3 to support the pipe to be cleaned, which facilitates the placement of the pipe to be cleaned. A motor 5 is also installed on the surface of the base plate 1 to provide power for the angle change of the conveying and cleaning power structure 3 and the cleaning support 4, which facilitates the adjustment of the angle of the conveying and cleaning power structure 3 and the cleaning support 4, so that the telescopic structure inside the conveying and cleaning power structure 3 can extend into the inside of the pipe to be cleaned.

[0027] The concrete transfer chamber 2 includes a transfer box 7 installed on the surface of the base plate 1. An regulating pipe 8 is installed inside the transfer box 7. A conveying pipe 9 is installed on the side of the transfer box 7 away from the conveying and cleaning power structure 3 at the position corresponding to the regulating pipe 8. Two connection ports 10 are opened on the other side of the transfer box 7 at the position corresponding to the regulating pipe 8, so that the conveying pipe 9 can be cyclically connected to the two connection ports 10, thereby ensuring that the concrete can be discharged along the direction of the regulating pipe 8 and the conveying pipe 9.

[0028] The top end of the regulating pipe 8 is connected to a fixing plate 12 via a connecting post 11. A rotating shaft 13 is installed on the side of the fixing plate 12. The rotating shaft 13 passes through and extends to the outer surface of the transfer box 7 and connects to a protrusion. A locking hole 14 is opened inside the protrusion. A locking ball 15 is rolled inside the locking hole 14. A support plate 17 is installed on the support column of the transfer box 7. A limit rod 18 is threadedly connected inside the support plate 17. An electric push rod 16 is installed on the limit rod 18 via a collar. The end of the electric push rod 16 is fixed to the side of the locking ball 15, thereby enabling the electric push rod 16 to extend and retract, which can drive the rotating shaft 13 to rotate back and forth, so that the regulating pipe 8 can connect to the two connecting ports 10 in sequence.

[0029] A feeding pipe 19 is installed on the transfer box 7 at the position corresponding to the connection port 10. It can be seen that there are two feeding pipes 19. A connecting rod 20 is slidably installed inside the feeding pipe 19. A piston plate 22 is installed on the side of the connecting rod 20. A top material head 21 is installed at one end of the connecting rod 20 corresponding to the connection port 10. A support plate 23 is installed on the surface of the bottom plate 1. This allows the top material head 21 and piston plate 22 to reciprocate when the connecting rod 20 moves. This not only makes it easier to draw the material in first and then push it out, but also effectively prevents concrete from adhering to the inner wall of the feeding pipe 19.

[0030] The conveying and cleaning power structure 3 includes a mounting box 24. Inside the mounting box 24, corresponding to the position of the feeding pipe 19, a hydraulic cylinder 26 is installed. Therefore, two hydraulic cylinders 26 are provided. A second connecting rod 28 is slidably mounted inside the hydraulic cylinder 26. A second piston plate 29 is installed at the end of the second connecting rod 28 away from the first connecting rod 20. A sleeve 30 is installed at the end of the second connecting rod 28 corresponding to the end of the first connecting rod 20. A clamp 31 is installed on the first connecting rod 20, which inserts into the sleeve 30. Both the clamp 31 and the sleeve 30 have threaded holes 32, with bolts 33 threaded into the threaded holes 32. A sealing sleeve 34 is wrapped around the position adjacent to the hydraulic cylinder 26 and the feeding pipe 19. An oil pump 25 is installed at the top of the mounting box 24. The oil pump 25 is connected to the hydraulic cylinder 26 via a pipe. The oil pump 25 first... Oil is transferred from one cylinder 26 to another, and then from the other cylinder 26 to the first cylinder 26, allowing oil to flow within both cylinders. This enables the connecting rod 28 inside the two cylinders to reciprocate. The bottom of the mounting box 24 is mounted on the surface of the base plate 1 via a support shaft 35. The support shaft 35 is connected to the output shaft of the motor 5 via a sprocket and chain drive structure 36. When the motor 5 is working, the sprocket and chain drive structure 36 drives the support shaft 35 to rotate, thereby adjusting the angle of the cylinder 26. The set rotation angle of the support shaft 35 is 90°. A support plate 27 is installed on the surface of the base plate 1 at a position corresponding to the area below the cylinder 26.

[0031] The pigging support 4 includes a mounting plate 39. The bottom end of the mounting plate 39 is connected to the base plate 1 via a second support shaft 37. The second support shaft 37 is connected to a first support shaft 35 via a second sprocket and chain drive structure 38. This allows the second support shaft 37 to rotate under the transmission of the second sprocket and chain drive structure 38 when the first support shaft 35 rotates. This enables the mounting plate 39 and the hydraulic cylinder 26 to rotate synchronously. When the set rotation angle is reached, the hydraulic cylinder 26 is directly above the mounting plate 39. The mounting plate 39 and the hydraulic cylinder 26 are arranged parallel to each other. The mounting plate 39 is located below the mounting box 24. An auxiliary oil tank is installed inside the mounting box 24. The mounting plate 39 has a mounting groove 40 inside. A lead screw 41 is rotatably mounted inside the mounting groove 40. A handle is installed on the outside of the lead screw 41, so that the lead screw 41 can be rotated by the handle.

[0032] A slide plate 42 is slidably mounted on the outside of the mounting plate 39. A screw seat 43 is mounted inside the slide plate 42 at the position corresponding to the screw 41. A support frame 44 is mounted on the surface of the slide plate 42. A support plate 45 is mounted on the surface of the base plate 1 at the position corresponding to the bottom of the mounting plate 39. A U-shaped groove 46 is mounted at the bottom of the slide plate 42. A rotating plate 48 is connected inside the U-shaped groove 46 through a rotating shaft 47. An inner tube 49 is mounted on the side of the rotating plate 48. An outer tube 50 is threadedly connected to the outside of the inner tube 49. By rotating the screw 41, the position of the slide plate 42 can be easily adjusted. By rotating the rotating plate 48, the inner tube 49 faces the ground. By adjusting the outer tube 50, it is inserted into the ground, thus facilitating the support operation of the rotated mounting plate 39.

[0033] When cleaning the inner wall of the pipe is required, first remove the sealing sleeve 34, then remove the bolt 33, thereby disconnecting the connection between connecting rod 1 20 and connecting rod 28. Simultaneously, the oil pump 25 draws oil from inside the cylinder 26 into the auxiliary oil tank inside the mounting box 24, ensuring that the connection between both connecting rods 1 20 and 28 can be disconnected at the same time. Then, the motor 5 is activated, and under the transmission of the sprocket chain drive structure 1 36 and sprocket chain drive structure 2 38, it drives the support shaft 1 35 and support shaft 2 37 to rotate 90° simultaneously. After rotation, the mounting plate 39 is positioned directly below the cylinder 26. Then, the handle is used to rotate the lead screw 41, thereby adjusting the distance between the slide plate 42 and the end of the cylinder 26. Finally, the oil pump 25 operates to draw oil from the auxiliary oil tank. Oil is injected into the cylinder 26, causing the end of the connecting rod 28 to extend. Then, a punch is connected inside the sleeve 30 via bolt 33. A tapered head is threaded onto the top of the punch, which can be selected according to the usage requirements. A through hole is provided at the position of the threaded hole 32 on the sleeve 30 to facilitate connection. After connection, the oil pump 25 is used to inject oil from the cylinder 26 back into the auxiliary oil tank. At this time, the pipe to be cleaned is installed in the support frame 44. Simultaneously, the screw 41 is rotated to bring the pipe to be cleaned closer to the position of the punch. Then, the oil pump 25 is used to inject oil from the auxiliary oil tank into the cylinder 26, causing the punch installed at the end of the connecting rod 28 to enter the inside of the pipe, thereby cleaning the inner wall of the pipe.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
