Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery, and in particular to a pumping system and a pump truck. Background Art

[0002] At present, the compatibility of domestic pumping systems, pump trucks and vehicle-mounted pumps is poor, resulting in the two different types of vehicles being unable to interchange and be used universally. That is, when customers need to pump floors higher than the pump truck boom, they must use a vehicle-mounted pump, and when they need to flexibly pump lower floors or other situations, they must use a pump truck for pumping. As a result, the same construction site must be equipped with both pump trucks and vehicle-mounted pumps for construction. On the one hand, this increases the construction party's cost, and on the other hand, it reduces construction efficiency and equipment utilization. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention provides a pumping system.

[0005] A second aspect of the present invention provides a pump truck.

[0006] In view of this, a first aspect of the present invention provides a pumping system, which includes: a hopper, one side of the hopper is connected to a pumping mechanism; a base, connected to the other side of the hopper; a discharge joint, a first end of the discharge joint is fixedly connected to the base; a hinge elbow, the hinge elbow is connected to the base or the discharge joint; wherein a connecting disk is provided on the outer peripheral surface of the second end of the discharge joint, and the discharge joint has two connection states, in the first state, the discharge joint is connected to the hinge elbow through the connecting disk, and in the second state, the discharge joint is connected to an external output pipe through the connecting disk.

[0007] In this technical solution, a pumping system is defined, and the pumping system includes a hopper, a base, and a discharge joint. The hopper is used to pump concrete, and the concrete is transported to a designated pipeline under the power provided by the hopper. The base is a positioning and connecting structure of the discharge joint, which is used to accurately position the discharge joint on the hopper. The base is connected to the hopper, and the first end of the discharge joint is fixedly connected to the base. After the connection is completed, the discharge joint is connected to the concrete outlet on the hopper, and the concrete pumped by the hopper is discharged to the outside of the hopper through the discharge joint. On this basis, the pumping system is also provided with a hinged elbow and an external output pipeline. A connecting plate is provided on the second end of the discharge joint, and the connecting plate can be connected to the hinged elbow and the external output pipeline respectively. In the first state, the discharge joint is connected to the hinged elbow through the connecting plate, so that the concrete pumped out of the hopper is transported to the concrete pipeline on the concrete pump truck through the hinged elbow. In the second state, the discharge joint is connected to the external output pipe through the connection plate, so that the concrete pumped out of the hopper is directly transported to the designated location in the building through the external output pipe. By setting a discharge joint that can be connected to the hinged elbow and the external output pipe, when it is necessary to use a pump truck to flexibly pump concrete to a lower area, the hinged elbow is connected to the discharge joint, and the outlet of the hinged elbow is connected to the delivery pipe on the boom of the pump truck, so that the concrete is delivered to the designated location through the extended boom. When it is necessary to pump concrete to an area whose height exceeds the boom height range of the pump truck, the external output pipe is connected to the discharge joint, and the outlet of the external output pipe is connected to the delivery pipe arranged in the building to pump the concrete to the designated location. As a result, a single hopper can be used for both concrete operations of pump trucks and truck-mounted pumps, avoiding the need to deploy pump trucks and truck-mounted pumps at the same construction site. On the one hand, the pump trucks and truck-mounted pumps can be used interchangeably, increasing the product’s applicable scope while reducing the construction costs. On the other hand, the switching process between pump trucks and truck-mounted pumps is eliminated, improving construction efficiency and equipment utilization. This has achieved the technical effect of optimizing the pumping system structure, improving the practicality and versatility of the pumping system, and enhancing product competitiveness.

[0008] In addition, the pumping system in the above technical solution provided by the present invention may also have the following additional technical features:

[0009] In the above technical solution, further, the discharge joint is detachably engaged with the hinge elbow, and the external output pipeline is detachably connected to the discharge joint.

[0010] In this technical solution, it is defined that the discharge joint and the hinge elbow can be detachably connected. When it is necessary to transport concrete to a specified position through the boom of the concrete pump truck, the hinge elbow is connected to the discharge joint. When the concrete transportation is completed or the connection needs to be switched, the hinge elbow is separated from the discharge joint. It is defined that the external output pipe is detachably connected to the discharge joint. When the user needs the pumping system to complete the pumping task of the vehicle-mounted pump, the external output pipe is connected to the discharge joint to pump the concrete through the external output pipe to the delivery pipe used by the vehicle-mounted pump and the delivery pipe arranged in the building, so as to pump the concrete to a high place. After the pumping task of the vehicle-mounted pump is completed, the external output pipe can be removed from the discharge joint to facilitate the movement of the equipment or the execution of the pumping task of the pump truck. Thereby optimizing the structure of the pumping system, improving the degree of freedom and operability of the structure, bringing convenient conditions for users to switch the working mode of the pumping system, and improving the technical effect of user experience.

[0011] In any of the above technical solutions, further, the external output pipeline includes: a conical tube; a first connecting part, which is sleeved on one end of the conical tube, and the first connecting part is connected to the connecting disk of the discharge joint.

[0012] In this technical solution, the structure of the external output pipeline is further limited. The external output pipeline includes a tapered tube and a first connecting portion. The narrow end of the tapered tube is connected to the delivery pipe used for the vehicle-mounted pump. The wide end is sleeved with a first connecting portion, and the first connecting portion is connected to the connecting plate on the discharge joint. By providing a first connecting portion connected to the discharge joint flange, the sealing and reliability of the connection can be improved on the basis of ensuring that the connection form is a detachable connection, thereby avoiding leakage problems during concrete delivery. Thereby achieving the technical effect of optimizing the structure of the pumping system and improving the connection reliability and stability of the external output pipeline.

[0013] In any of the above technical solutions, further, the pumping system also includes: a pipe clamp. In the second state, the pipe clamp is sleeved around at least part of the first connecting part and the connecting disk, and the pipe clamp clamps the connected first connecting part and the connecting disk.

[0014] In this technical solution, a pipe clamp is also provided on the pumping system, and the pipe clamp sleeve is provided in the connection area between the external output pipe and the connection plate, specifically located at least part of the first connection part and the peripheral side of the connection plate. During operation, after the flange connection between the first connection part and the connection plate is completed, the pipe clamp sleeve is provided in the flange connection area, and then the external output pipe and the connection plate are clamped by the fastening structure on the pipe clamp to ensure that the external output pipe and the discharge joint are closely connected, and the two are prevented from loosening and dislocation during operation, thereby further improving the connection reliability of the discharge joint and the external output pipe. Thus, the technical effect of improving the structural stability of the pumping system and improving the working reliability is achieved.

[0015] In any of the above technical solutions, further, the discharge joint includes: a main body, which is provided with a penetrating conical hole; a connecting flange, which is sleeved on the main body, the connecting flange is located at the first end of the main body, the connecting plate is located at the second end of the main body, and the connecting flange is connected to the base; a sealing groove, which is arranged on the end face of the connecting plate away from the connecting flange, and the sealing groove is arranged around the conical hole.

[0016] In this technical solution, the structure of the discharge joint is specifically defined. The discharge joint includes a body and a connecting flange. A through conical hole is provided on the body, the first end of the conical hole is connected to the concrete outlet on the hopper, and the second end of the conical hole is connected to the hinge elbow or the external output pipe. The connecting flange is sleeved on the first end of the conical hole to position and install the discharge joint on the base through the connecting flange. The positioning accuracy and connection reliability of the discharge joint can be ensured by setting the connecting flange, and the concrete can be effectively prevented from leaking from the connection area between the discharge joint and the base. On this basis, a sealing groove arranged around the conical hole is also provided on the end surface of the connection plate away from the connecting flange, and an annular sealing member is provided in the sealing groove. When the hinge elbow or the external output pipe is in contact with the discharge joint, the sealing member in the sealing groove contacts the connection end surface of the hinge elbow or the connection end surface of the external output pipe, thereby effectively sealing the connection gap between the discharge joint and the hinge elbow and the connection gap between the discharge joint and the external output pipe. This achieves the technical effect of optimizing the discharge joint structure, improving the positioning accuracy and connection reliability of the discharge joint, and improving the working stability of the pumping system.

[0017] Among them, the connecting flange and the main body are an integrated structure. By setting the connecting flange and the main body as an integrated structure, on the one hand, the existence of a connecting section between the two can be avoided, thereby improving the overall strength of the discharge joint. On the other hand, the structure of the discharge joint can be simplified, the assembly difficulty of the discharge joint can be reduced, and the production cost of the discharge joint can be reduced.

[0018] In any of the above technical solutions, further, a first groove is provided on the circumferential side surface of the connecting plate close to the connecting flange on the main body, and a second groove is provided on the circumferential side surface of the first connecting part; a first boss and a second boss are provided on the inner side surface of the pipe clamp, and when the pipe clamp clamps the discharge joint and the external output pipe, the first boss is located in the first groove, and the second boss is located in the second groove.

[0019] In this technical solution, the matching connection structure of the pipe clamp, the first connection part and the discharge joint is specifically defined. A first groove is provided on the peripheral side surface of the connection plate on the main body close to the connecting flange, a second groove is provided on the peripheral side surface of the first connection part, and a first boss and a second boss are correspondingly provided on the inner side surface of the pipe clamp. When the pipe clamp sleeve is arranged on the peripheral side of the first connection part and the discharge joint, the first boss is positioned in the first groove, and the second boss is positioned in the second groove, so as to achieve a close fit between the inner surface of the pipe clamp and the outer surface of the discharge joint and the first connection part. By providing a matching connection structure of the groove and the boss, on the one hand, the positioning accuracy of the pipe clamp can be improved, which is convenient for the user to accurately set the pipe clamp sleeve in the correct position. On the other hand, the clamping effect of the pipe clamp can be improved, and the connection reliability between the discharge joint and the external output pipeline can be further improved.

[0020] Wherein, matching inclined surfaces are correspondingly arranged on the first boss and the first groove as well as the second boss and the second groove. The positioning accuracy and connection reliability of the pipe clamp can be further enhanced by arranging the matching inclined surfaces.

[0021] In any of the above technical solutions, further, a hinged rod and a plug-in rod are provided on the base, the hinged elbow is hingedly connected to the hinged rod, the hinged elbow is detachably connected to the plug-in rod, and the hinged elbow can rotate relative to the base.

[0022] In this technical solution, the hinged bend is arranged on the base, and the hinged bend can move relative to the base. Specifically, a hinge rod and a plug rod are arranged on the base. The hinged bend and the hinged rod are hinged to each other, so that the hinged bend can rotate relative to the base, and the hinged bend is detachably connected to the plug rod. During operation, when the pumping system needs to perform the pumping task of the pump truck, the hinged bend is rotated to a specified position and the hinged bend is connected to the plug rod, and then the outlet end of the hinged bend is connected to the delivery pipe on the pump truck. Conversely, after completing the concrete pumping task of the pump truck, the connection between the hinged bend and the delivery pipe and the connection between the hinged bend and the plug rod are disconnected, and then the hinged bend is moved to the initial position. By hingedly connecting the hinged bend to the base, on the one hand, it can provide convenient conditions for users to disassemble and assemble the hinged bend, and on the other hand, it can improve the connection accuracy and reliability of the hinged bend and the discharge joint.

[0023] In any of the above technical solutions, further, the hinged elbow includes: a positioning plate, which is hinged to the hinge rod on the base, and a second connecting part is arranged on the positioning plate; a elbow, one end of which is passed through the positioning plate; wherein, after the positioning plate is rotated to the position where the elbow is connected to the discharge joint, the plug-in rod is connected to the second connecting part.

[0024] In the technical scheme, the structure of the hinge elbow is specifically defined. The hinge elbow is composed of a positioning plate and an elbow, and one end of the elbow is inserted into the positioning plate. One end of the positioning plate is hinged to the hinge rod on the base, and the positioning plate is also provided with a second connecting portion, and a plug-in rod is provided at the corresponding position on the base. During operation, when it is necessary to connect the discharge joint and the hinge elbow, the hinge elbow is flipped to the specified position so that the elbow is connected to the discharge joint, and the connection end face of the elbow is ensured to be in close contact with the seal in the sealing groove, and then the plug-in rod and the second connecting portion are connected together to fix the hinge elbow at the above-mentioned specified position. By hingedly connecting the positioning plate and the hinge rod, it is convenient to accurately move the hinge elbow to the specified position connected to the discharge joint, reducing the difficulty of operation for users. By providing the plug-in rod and the second connecting portion, the connection stability and reliability of the hinge elbow and the discharge joint can be guaranteed, and the hinge elbow and the discharge joint can be prevented from loosening and dislocation during operation. Thereby achieving the technical effect of improving the structural stability and working reliability of the pumping system.

[0026] In this technical solution, the structure of the plug-in rod and the second connecting part is specifically defined. The plug-in rod is a column, and the second connecting part is a through hole that matches the column, wherein a pin hole is provided on the column. During the connection process, the hinge elbow is rotated so that the column part passes through the through hole. After ensuring that the connection position of the hinge elbow and the discharge joint is correct, the plug pin is inserted into the pin hole passing through the through hole to complete the connection. By providing the above-mentioned connection structure, on the one hand, it can be ensured that the hinge elbow can be tightly fastened to the discharge joint, thereby improving the connection reliability of the hinge elbow and the discharge joint. On the other hand, the structure is simple and quick to operate, and can realize the rapid connection of the hinge elbow, thereby significantly improving the connection efficiency and reducing the connection difficulty. This can optimize the structure of the hinge elbow and the discharge joint, improve the connection reliability of the hinge elbow and the discharge joint, provide convenient conditions for users, and enhance the technical effect of user experience.

[0028] In this technical solution, a product using the pumping system in any of the above technical solutions is specifically defined. The product is a pump truck, which includes a vehicle body, a boom and a pumping system. The boom and the pumping system are positioned and installed on the vehicle body. During operation, when it is necessary to flexibly pump concrete to an area with a lower height, the vehicle body moves to the vicinity of the area, the discharge joint on the pumping system is connected to the inlet of the hinged elbow, and the outlet of the hinged elbow is connected to the delivery pipe on the boom, and then the boom is controlled to extend to a specified position to pump the concrete to the specified position through the hinged elbow and the delivery pipe on the boom through the hopper. When it is necessary to pump concrete to an area with a higher height, disconnect the connection of the hinged elbow, connect the external output pipeline to the discharge joint, and connect the outlet end of the external output pipeline to the delivery pipe for the pump truck, which is connected to the concrete delivery pipeline laid in the construction building, and then the hopper increases the pumping power to pump the concrete to the specified position.

On the one hand, the pump truck and the vehicle-mounted pump are universal, reducing the cost of the construction party, and on the other hand, the switching process of the pump truck and the vehicle-mounted pump is eliminated, improving the construction efficiency and equipment utilization rate. In turn, the technical effect of strengthening the function of the pump truck, increasing the applicable scope of the pump truck, improving the user experience, and improving the competitiveness of the product is achieved.

It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0040] Refer to the following Figures 1 to 5 The pumping system 1 and the pump truck provided according to some embodiments of the present invention are described.

[0041] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, a pumping system 1 is provided, and the pumping system 1 includes: a hopper 10, one side of the hopper 10 is connected to a pumping mechanism; a base 20, connected to the other side of the hopper 10; a discharge joint 30, a first end of the discharge joint 30 is fixedly connected to the base 20; a hinge elbow 40, the hinge elbow 40 is connected to the base 20 or the discharge joint 30; wherein, a connecting disk 301 is provided on the outer peripheral surface of the second end of the discharge joint 30, and the discharge joint 30 has two connection states, in the first state, the discharge joint 30 is connected to the hinge elbow 40 through the connecting disk 301, and in the second state, the discharge joint 30 is connected to the external output pipe 50 through the connecting disk 301.

[0042] In this embodiment, a pumping system 1 is defined, and the pumping system 1 includes a hopper 10, a base 20, and a discharge joint 30. The hopper 10 is used to pump concrete, and the concrete is transported to a designated pipeline under the power provided by the hopper 10. The base 20 is a positioning and connecting structure of the discharge joint 30, which is used to accurately position the discharge joint 30 on the hopper 10. The base 20 is connected to the hopper 10, and the first end of the discharge joint 30 is fixedly connected to the base 20. After the connection is completed, the discharge joint 30 is connected to the concrete outlet on the hopper 10, and the concrete pumped by the hopper 10 is discharged from the discharge joint 30 to the outside of the hopper 10. On this basis, the pumping system 1 is also provided with a hinged elbow 40 and an external output pipeline 50. A connecting plate 301 is provided on the second end of the discharge joint 30, and the connecting plate 301 can be connected to the hinged elbow 40 and the external output pipeline 50 respectively. In the first state, the discharge joint 30 is connected to the hinge elbow 40 through the connection plate 301, so that the concrete pumped out of the hopper 10 is transported to the concrete pipeline on the concrete pump truck through the hinge elbow 40. In the second state, the discharge joint 30 is connected to the external output pipe 50 through the connection plate 301, so that the concrete pumped out of the hopper 10 is directly transported to the designated location in the building through the external output pipe 50.

[0043] By setting a discharge joint 30 that can be connected to the hinged elbow 40 and the external output pipe 50, when a pump truck is needed to flexibly pump concrete to a lower height area, the hinged elbow 40 is connected to the discharge joint 30, and the outlet of the hinged elbow 40 is connected to the delivery pipe on the boom of the pump truck, so that the concrete is delivered to the designated location through the extended boom. When it is necessary to pump concrete to an area whose height exceeds the boom height range of the pump truck, the external output pipe 50 is connected to the discharge joint 30, and the outlet of the external output pipe 50 is connected to the delivery pipe arranged in the building to pump concrete to the designated location. In this way, a single hopper 10 can be used for both concrete operations of pump trucks and concrete operations of vehicle-mounted pumps, avoiding the simultaneous arrangement of pump trucks and vehicle-mounted pumps in the same construction site area. On the one hand, the universal use of pump trucks and vehicle-mounted pumps is achieved, which increases the product application range while reducing the construction party's cost. On the other hand, the switching process of pump trucks and vehicle-mounted pumps is eliminated, which improves construction efficiency and equipment utilization. This achieves the technical effect of optimizing the structure of the pumping system 1, improving the practicality and versatility of the pumping system 1, and enhancing product competitiveness.

[0044] In one embodiment of the present invention, preferably, Figure 1 and Figure 2 As shown, the discharge connector 30 is detachably engaged with the hinge elbow 40 , and the external output pipe 50 is detachably connected to the discharge connector 30 .

[0045] In this embodiment, it is defined that the discharge joint 30 is detachably connected to the hinge elbow 40. When the concrete needs to be transported to a specified position through the boom of the concrete pump truck, the hinge elbow 40 is connected to the discharge joint 30. When the concrete delivery is completed or the connection needs to be switched, the hinge elbow 40 is separated from the discharge joint 30. It is defined that the external output pipe 50 is detachably connected to the discharge joint 30. When the user needs the pumping system 1 to complete the pumping task of the vehicle-mounted pump, the external output pipe 50 is connected to the discharge joint 30 to pump the concrete through the external output pipe 50 to the delivery pipe used by the vehicle-mounted pump and the delivery pipe arranged in the building, so as to pump the concrete to a high place. After the pumping task of the vehicle-mounted pump is completed, the external output pipe 50 can be disassembled from the discharge joint 30 to facilitate the movement of the equipment or the execution of the pumping task of the pump truck. In this way, the structure of the pumping system 1 is optimized, the degree of freedom and operability of the structure are improved, and convenient conditions are brought to the user to switch the working mode of the pumping system 1, and the technical effect of improving the user experience is achieved.

[0046] In one embodiment of the present invention, preferably, Figure 3 As shown, the external output pipeline 50 includes: a conical tube 502; a first connecting portion 504, which is sleeved on one end of the conical tube 502, and the first connecting portion 504 is connected to the connecting plate 301 of the discharge connector 30.

[0047] In this embodiment, the structure of the external output pipeline 50 is further limited. The external output pipeline 50 includes a tapered tube and a first connecting portion 504. The narrow end of the tapered tube is connected to the delivery pipe used for the vehicle-mounted pump. The wide end is sleeved with a first connecting portion 504, and the first connecting portion 504 is connected to the connecting plate 301 on the discharge connector 30. By providing the first connecting portion 504 flange-connected to the discharge connector 30, the sealing and reliability of the connection can be improved on the basis of ensuring that the connection form is a detachable connection, thereby avoiding leakage problems during the concrete delivery process. Thereby achieving the technical effect of optimizing the structure of the pumping system 1 and improving the connection reliability and stability of the external output pipeline 50.

[0048] In one embodiment of the present invention, preferably, Figure 3 As shown, the pumping system 1 further includes: a pipe clamp 60. In the second state, the pipe clamp 60 is sleeved around at least part of the first connecting portion 504 and the connecting disk 301, and the pipe clamp 60 clamps the connected first connecting portion 504 and the connecting disk 301.

[0049] In this embodiment, the pumping system 1 is further provided with a pipe clamp 60, which is sleeved on the connection area between the external output pipe 50 and the connection disk 301, specifically located at least partially around the first connection part 504 and the connection disk 301. During operation, after the flange connection between the first connection part 504 and the connection disk 301 is completed, the pipe clamp 60 is sleeved on the flange connection area, and then the external output pipe 50 and the connection disk 301 are clamped by the fastening structure on the pipe clamp 60, so as to ensure that the external output pipe 50 and the discharge connector 30 are closely connected, and looseness and misalignment between the two are avoided during operation, thereby further improving the connection reliability between the discharge connector 30 and the external output pipe 50. Thus, the technical effect of improving the structural stability of the pumping system 1 and improving the working reliability is achieved.

[0050] In one embodiment of the present invention, preferably, Figure 4 and Figure 5 As shown, the discharge connector 30 includes: a main body 302, on which a conical hole is provided; a connecting flange 304, which is sleeved on the main body 302, the connecting flange 304 is located at the first end of the main body 302, the connecting plate 301 is located at the second end of the main body 302, and the connecting flange 304 is connected to the base 20; a sealing groove 306, which is arranged on the end face of the connecting plate 301 away from the connecting flange 304, and the sealing groove 306 is arranged around the conical hole.

[0051] In this embodiment, the structure of the discharge joint 30 is specifically defined. The discharge joint 30 includes a body 302 and a connecting flange 304. A through conical hole is provided on the body 302, the first end of the conical hole is connected to the concrete outlet on the hopper 10, and the second end of the conical hole is connected to the hinge elbow 40 or the external output pipe 50. The connecting flange 304 is sleeved on the first end of the conical hole, so that the discharge joint 30 is positioned and installed on the base 20 through the connecting flange 304. By setting the connecting flange 304, the positioning accuracy and connection reliability of the discharge joint 30 can be guaranteed, and the leakage of concrete from the connection area between the discharge joint 30 and the base 20 can be effectively avoided. On this basis, a sealing groove 306 arranged around the conical hole is further arranged on the end surface of the connection plate 301 away from the connection flange 304, and an annular sealing member is arranged in the sealing groove 306. When the hinge elbow 40 or the external output pipe 50 is in contact with the discharge joint 30, the sealing member in the sealing groove 306 is in contact with the connection end surface of the hinge elbow 40 or the connection end surface of the external output pipe 50, thereby effectively sealing the connection gap between the discharge joint 30 and the hinge elbow 40 and the connection gap between the discharge joint 30 and the external output pipe 50. Thus, the technical effect of optimizing the structure of the discharge joint 30, improving the positioning accuracy and connection reliability of the discharge joint 30, and improving the working stability of the pumping system 1 is achieved.

[0052] Among them, the connecting flange 304 and the main body 302 are an integrated structure. By setting the connecting flange 304 and the main body 302 as an integrated structure, on the one hand, the existence of a connecting section between the two can be avoided, thereby improving the overall strength of the discharge connector 30.
