[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0041] To facilitate understanding of the integrated concrete mixing, transporting, and pumping vehicle provided by this invention, its application background is first explained. Concrete pier support is one of the support methods for roadways. In related technologies, it is generally necessary to use a combination of equipment such as a mining concrete mixing and transporting vehicle, a concrete mixer, and a trailer-mounted concrete pump to pour concrete piers in the mine. This method suffers from problems such as complex construction processes, high consumption of roadway and human resources, low mechanization, high labor intensity, and low efficiency. Therefore, this invention provides an integrated concrete mixing, transporting, and pumping vehicle that can simplify the construction process, reduce the occupation of manpower and equipment, alleviate the labor intensity of workers, and improve construction efficiency.

[0042] The following is combined Figures 1-5 The present invention describes a concrete mixing, transporting, and pumping integrated vehicle.

[0043] Reference Figure 1 A concrete mixing, transporting, and pumping integrated vehicle includes a vehicle body 1, a mixing tank 2, a robotic arm 3, a discharge pipe 4, and a pumping system 5; wherein, the vehicle body 1 includes a cab 10 and a chassis 11; the mixing tank 2 is rotatably supported on the chassis 11 and is used for mixing concrete; the robotic arm 3 is mounted on the cab 10, and its end away from the cab 10 is a free end, which can extend or retract with the movement of the robotic arm 3.

[0044] The discharge pipe 4 is laid along the robotic arm 3, and a discharge port is provided at one end of the discharge pipe 4 near the free end of the robotic arm 3; the pumping system 5 is used to pump the concrete in the mixing tank 2 in conjunction with the discharge pipe 4.

[0045] In practical operation, the vehicle body 1 transports concrete to the mine shaft. The rotating mixing tank 2 mixes the concrete, preventing it from solidifying. When pouring the pier, the movement of the robotic arm 3 extends its free end to a predetermined position, moving the discharge port of the discharge pipe 4 to that position. The pumping system 5 works in conjunction with the discharge pipe 4 to pump the concrete from the mixing tank 2, thus pouring the pier at the designated location. After pouring, the robotic arm 3 retracts the discharge pipe 4, and the vehicle body 1 moves on to begin the next pouring operation. Compared to the traditional method of using a mining concrete mixer truck, concrete mixer, and trailer-mounted concrete pump, this method simplifies the construction process, reduces manpower and equipment requirements, alleviates the labor intensity of workers, and improves construction efficiency. Furthermore, the robotic arm 3 is mounted on the vehicle's cab 10, making the vehicle body 1 more compact and allowing for a larger proportion of the mixing tank 2, resulting in a higher transport capacity within the same vehicle body.

[0046] Reference Figure 1 and Figure 2 The chassis 11 of the vehicle body 1 is equipped with a mounting base 110 to provide an installation position for the mixing tank 2. The mixing tank 2 is rotatably supported on the mounting base 110, with one end close to the cab 10 and the other end away from the cab 10. The end of the mixing tank 2 away from the cab 10 is an open end, used for adding materials into the mixing tank 2 or for discharging materials after mixing. The vehicle body 1 is equipped with a power system for driving the mixing tank 2 to rotate. Driven by the power system, the mixing tank 2 can rotate on the mounting base 110. By controlling different rotation states of the mixing tank 2, concrete can be mixed or discharged.

[0047] It should be noted that the mixing tank 2 and its associated power system are both mature existing technologies. Since their own structure is not the point of invention of this invention, and this invention does not involve any changes to the structure of the mixing tank 2 itself, the specific structure and working principle of the mixing tank 2 will not be described in detail here.

[0048] A feed hopper 20 is connected to the open end of the mixing tank 2, allowing material to be fed into the mixing tank 2. With the forward direction of the vehicle body 1 set as forward, the robotic arm 3 is positioned in front of the driver's cab 10. This allows the driver to see the position of the robotic arm 3 and the discharge port, determine whether the robotic arm 3 has reached the pouring position, observe the pouring process during pouring, and easily operate the robotic arm 3. It also facilitates the driver's control of the vehicle body 1's position and speed, making operation within the mine easier. Furthermore, the robotic arm 3 and the feed hopper 20 do not interfere with or affect each other.

[0049] Specifically, the robotic arm 3 includes a folding arm 30 and a drive unit 31; wherein, the folding arm 30 includes multiple arm units, and the ends of each pair of adjacent arm units are hinged, so that the folding arm 30 as a whole can be extended or folded for storage, so as to adjust the position of the discharge port.

[0050] The extension direction of the folding arm 30 can be selected according to actual needs. Understandably, to facilitate multi-directional adjustment of the discharge port, in another embodiment, the end of the folding arm 30 furthest from the discharge port can be connected to the cab 10 via a slewing bearing or a spherical bearing, allowing the folding arm 30 to swing as needed while extending and retracting, thus achieving flexible adjustment of the discharge port position. It should be noted that slewing bearings and spherical bearings are mature existing technologies, therefore their specific structures and installation methods will not be described in detail.

[0051] The driving component 31 is a hydraulic cylinder. A hydraulic cylinder is provided between each pair of adjacent arm units. The cylinder body of the hydraulic cylinder is hinged to one of the arm units, and the piston rod is hinged to the other arm unit. In this way, when a single hydraulic cylinder extends or retracts, the adjacent arm units can rotate around the hinge point to extend or fold. Through the cooperation between multiple hydraulic cylinders, the extension and folding of the entire folding arm 30 is driven.

[0052] In another embodiment, the drive element 31 can also be equivalently replaced by a linear drive element 31 such as a cylinder or electric actuator, or a rotary drive element 31 composed of a motor and its cooperating gears. When the drive element 31 is a linear drive element 31, its connection method is the same as that of a hydraulic cylinder. When a rotary drive element 31 is used, it is only necessary to enable it to drive the hinge axis of the adjacent arm unit to rotate. It is understood that the drive element 31 is not limited to the structures or methods listed above, and other structures capable of driving the folding arm 30 to extend or fold are also applicable to this invention.

[0053] The pumping system 5 includes a pumping hopper 50 and a concrete pump 51. The pumping hopper 50 is fixedly connected to the chassis 11 of the vehicle body 1 and is located directly below the open end of the mixing tank 2. It is used to receive the material discharged from the open end. When the mixing tank 2 discharges material, the concrete falls into the pumping hopper 50 under the action of gravity. The concrete pump 51 is connected to the pumping hopper 50 and the discharge pipe 4. During pouring, it is used to cooperate with the discharge pipe 4 to pump the material in the pumping hopper 50 to a predetermined position.

[0054] Specifically, a discharge hopper 6 is provided between the open end of the mixing tank 2 and the pumping hopper 50. The discharge hopper 6 has openings at both the top and bottom. The upper opening is flared and located near the open end of the mixing tank 2 to receive the material discharged from the mixing tank 2. The bottom opening corresponds to the pumping hopper 50. Through the discharge hopper 6, the material discharged from the mixing tank 2 can be accurately guided into the pumping hopper 50.

[0055] Specifically, the discharge hopper 6 is fixedly connected to the chassis 11 of the vehicle body 1. For example, the discharge hopper 6 can be fixedly connected to the mounting base 110 of the mixing tank 2 to secure it; alternatively, a mounting bracket can be fixed to the chassis 11 of the vehicle body 1, and the discharge hopper 6 can be fixedly connected to the mounting bracket to secure it to the chassis 11. In short, regardless of the method used, it is sufficient to secure the discharge hopper 6 between the open end of the mixing tank 2 and the pumping hopper 50.

[0056] Reference Figure 2 The integrated concrete mixing, transporting, and pumping vehicle also includes a discharge chute 7; the discharge chute 7 can be inserted between the discharge hopper 6 and the pumping hopper 50, thereby separating the open end of the mixing tank 2 and the pumping hopper 50, so that the concrete in the mixing tank 2 has two discharge routes. One is that the concrete enters the pumping hopper 50 and is pumped out by the concrete pump 51 along the discharge port of the discharge pipe 4. The position of the discharge port can be controlled by the robotic arm 3, which can freely extend and fold to realize fully mechanized pumping operations; the other is that it is directly discharged through the discharge chute 7, which is used for discharge of concrete pump 51 in case of failure and discharge of residual material.

[0057] Specifically, the unloading trough 7 has a trough-shaped structure. One end has a large opening width to match the bottom opening of the discharge hopper 6 and receive the material discharged from the open end of the mixing tank 2. The other end is inclined downward so that the material can be discharged along the unloading trough 7 under the action of gravity.

[0058] The unloading chute 7 is slidably connected to the chassis 11 of the vehicle body 1 via the sliding connector 8, so that the unloading chute 7 can move toward the discharge hopper 6 to separate the open end of the mixing tank 2 and the pumping hopper 50, or move away from the discharge hopper 6 so that concrete materials can enter the pumping hopper 50.

[0059] Specifically, a connecting rod 70 is fixedly connected to each of the opposite sides of the unloading chute 7; the sliding connector 8 includes a guide rail 80 and a slider 81; wherein, the guide rail 80 is fixedly connected to the chassis 11 of the vehicle body 1 by means of a support rod or support frame, and two guide rails 80 are provided and respectively arranged on both sides of the discharge hopper 6, the two guide rails 80 are spaced apart and extend in a direction parallel to the vehicle's direction of travel. The slider 81 is constrained on the guide rail 80 and can slide back and forth along the length of the guide rail 80; the unloading chute 7 is disposed between the two guide rails 80, and the connecting rods 70 on both sides are fixedly connected to the slider 81 on the two guide rails 80 respectively. Through the mutual cooperation of the guide rails 80 and slider 81, the sliding of the unloading chute 7 can be restricted and guided, improving the stability and smoothness of the sliding of the unloading chute 7.

[0060] Specifically, each of the two guide rails 80 has a guide groove on its opposite side. The guide groove extends along the length of the guide rail 80, and the slider 81 is slidably embedded in the guide groove.

[0061] Specifically, the slider 81 can be a spherical structure or a wheel-shaped structure, which can reduce the frictional resistance between the slider 81 and the guide rail 80 and improve the smoothness of the sliding of the unloading groove 7.

[0062] Specifically, refer to Figure 3 and Figure 4 The connecting rod 70 and the slider 81 can be rotatably connected. The connecting rod 70 is close to the end with a larger opening width of the unloading chute 7. After the unloading chute 7 slides and inserts into the bottom of the discharge hopper 6, it is kept stable by the limit at the bottom of the discharge hopper 6. After the unloading chute 7 slides out, it is rotated to change its state from an inclined state to a state perpendicular to the chassis 11, thereby avoiding interference with the discharge hopper 6 and the pumping hopper 50.

[0063] It is understandable that the above connection method between the guide rail 80 and the slider 81 is only one of many connection methods between the two. Other connection methods that only require the slider 81 to slide on the guide rail 80 are also applicable.

[0064] It is understood that the sliding connector 8 is not limited to the guide rail 80 and slider 81 mentioned above. Other structures, such as cooperating cylindrical shafts and linear bearings, guide rods and guide sleeves, etc., as long as they can enable the unloading groove 7 to slide on the chassis 11, are all applicable to this invention.

[0065] Reference Figure 1 and Figure 5 The vehicle body 1 is driven by the hydraulic power mechanism 9, which eliminates the need for a complex transmission system. On the one hand, this helps to increase the proportion of the mixing tank 2, thereby increasing the transport capacity. On the other hand, it allows for sufficient installation space on the chassis 11. By installing the concrete pump 51 under the mixing tank 2, the overall vehicle structure becomes more compact and smaller, with a lower height, making it easier to move around in the mine and suitable for working conditions in narrow underground tunnels.

[0066] Specifically, the hydraulic power mechanism 9 includes an engine hydraulic pump assembly 90, hydraulic lines 91, a hydraulic distributor 92, and a hydraulic motor 93. The engine hydraulic pump assembly 90 is used to provide hydraulic pressure. There are two hydraulic motors 93, which are respectively connected to the rear wheels 12 of the vehicle body 1. The engine hydraulic pump assembly 90 is connected to the hydraulic motors 93 through the hydraulic lines 91 and the hydraulic distributor 92. The engine hydraulic pump assembly 90 drives the hydraulic motors 93 to operate, thereby providing driving force to the rear wheels 12 of the vehicle body 1 and driving the vehicle body 1 to move.

[0067] Specifically, all components inside this integrated concrete mixing, transporting, and pumping vehicle are explosion-proof, meeting the explosion-proof requirements for mining equipment.

[0068] Specifically, the integrated concrete mixing, transporting, and pumping vehicle is equipped with a safety monitoring and protection device. This device can collect various operating parameters, such as voltage, current, oil pressure, and water pressure, and control the opening and closing of various components based on the feedback of these parameters. For example, when a parameter exceeds a threshold, the device will actively control the integrated concrete mixing, transporting, and pumping vehicle to stop working. Furthermore, the safety monitoring and protection device includes a recording module and a storage module; when a parameter exceeds a threshold, the relevant data can be recorded and saved.

[0069] The novelty of this invention lies in the following: A vehicle 1 transports concrete to the mine shaft, while a rotating mixing tank 2 mixes the concrete, preventing it from solidifying. During the pier pouring, a robotic arm 3 moves the discharge port of the discharge pipe 4 to a predetermined position, and a pumping system 5 works in conjunction with the discharge pipe 4 to pump the concrete from the mixing tank 2, thus ensuring the pier is poured at the designated location. Compared to the traditional method of using a mining concrete mixer truck and a trailer-mounted concrete pump, this simplifies the construction process, reduces manpower and equipment requirements, alleviates the labor intensity of workers, and improves construction efficiency. In addition, the robotic arm 3 is installed on the driver's cab 10 of the vehicle, making the structure of the vehicle body 1 more compact and smaller, increasing the proportion of the mixing tank 2, and having a higher transport capacity under the same vehicle body. The driver can see the position of the robotic arm 3 and the discharge port, determine whether the robotic arm 3 has reached the pouring position, and observe the pouring situation during pouring. This makes it easier for the driver to operate the robotic arm 3, and at the same time, it is convenient for the driver to control the movement position and speed of the vehicle body 1, which is convenient for operation in the mine.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
