In addition, it should be noted that the terms such as "first", "second", etc. are used to distinguish one element from another, and do not have sequence and importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.
[0027] In the description of the present disclosure, it should also be noted that, unless otherwise clearly specified and defined, the terms "arranged", "connected", "coupled", and "installed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0028] Referring Figure 1 to Figure 2 As shown, the present disclosure provides a combined system of a concrete pump truck and a mixer truck, including a mixer truck 10, a concrete pump truck 20, and a controller. The mixer truck 10 includes a mixer truck body 11, a mixing drum 12, a discharge hopper 13, a lifting mechanism 14, and a position detection mechanism 15. The mixing drum 12 is arranged on the mixer truck body 11. The discharge hopper 13 is arranged below the discharge port of the mixing drum 12, and one end of the discharge hopper 13 close to the mixer truck body 11 is hinged to the mixer truck body 11. One end of the lifting mechanism 14 is connected to the vehicle body, and the other end of the lifting mechanism 14 is connected to the discharge hopper 13. The position detection mechanism 15 is arranged on the mixer truck body 11. The concrete pump truck 20 includes a material height measuring mechanism 21, a concrete pump truck body 22, and a concrete pump truck hopper 23 arranged on the concrete pump truck body 22. The material height measuring mechanism 21 is arranged on the concrete pump truck hopper 23. The controller is respectively in signal connection with the lifting mechanism 14, the position detection mechanism 15, and the material height measuring mechanism 21.
[0029] Through the above technical solution, the position detection mechanism 15 is arranged on the mixer truck body 11, and the controller is respectively in signal connection with the position detection mechanism 15 and the material height measuring mechanism 21. In this way, when discharging is required, the position detection mechanism 15 can detect the positions of the concrete pump truck 20 and the concrete pump truck hopper 23, and then transmit the position information to the controller. The controller then controls the lifting mechanism 14 to lift or lower the height of the discharge hopper 13 according to the position information, so that the material flowing out of the discharge hopper 13 can accurately enter the concrete pump truck hopper 23. At the same time, the material height detection mechanism arranged on the concrete pump truck hopper 23 can detect the stacking height of the material in the concrete pump truck hopper 23, so as to immediately judge the stacking situation in the concrete pump truck hopper 23, avoid problems of overflow or suction empty caused by too fast or too slow filling, further improve the discharging efficiency and discharging effect, and moreover, during the above discharging process, no manual intervention is required, which can greatly reduce the labor intensity of workers, reduce the labor cost and safety hazards, and has strong practicability.
[0030] In an exemplary embodiment provided by the present disclosure, the above-mentioned controller may be an in-vehicle computer of a vehicle. In this way, in an embodiment where the lifting mechanism 14, the position detection mechanism 15, and the material height measurement mechanism 21 are all connected to the in-vehicle computer by signals, the in-vehicle computer may control the lifting or lowering of the lifting mechanism 14 according to the position information of the pump truck hopper 23 detected by the position detection structure, so that the material can accurately enter the hopper of the pump truck through the discharge hopper 13. The in-vehicle computer may also control the discharge speed according to the material accumulation height information collected by the material height detection structure, avoiding problems such as overflow or air suction caused by too fast or too slow filling, and improving the user experience.
[0031] The above-mentioned lifting mechanism 14, position detection mechanism 15, and material height measurement mechanism 21 may be connected to the in-vehicle computer by signals in a wired or wireless manner. For example, the lifting mechanism 14 and the position detection mechanism 15 may be connected to the in-vehicle computer of the mixer truck 10 through a first wireless communication module 30 such as a vehicle networking platform. The material height measurement mechanism 21 may be connected to the in-vehicle computer of the mixer truck 10 or the in-vehicle computer through a second wireless communication module 40 such as a vehicle networking platform. As Figure 1 shown, the above-mentioned first wireless communication module 30 may be arranged on the mixer truck body 11. Similarly, the second wireless communication module 40 may be arranged on the pump truck body 22. The above-mentioned lifting mechanism 14, position detection mechanism 15, and material height measurement mechanism 21 may also be connected to the in-vehicle computer by signals through a telematics processor. The present disclosure does not limit this.
[0032] Optionally, in an exemplary embodiment provided by the present disclosure, as Figure 1 shown, the above-mentioned lifting mechanism 14 may be a first hydraulic cylinder. The first hydraulic cylinder includes a first cylinder body 141 and a first piston rod 142. One end of the first cylinder body 141 away from the first piston rod 142 is hinged to the mixer truck body 11, and one end of the first piston rod 142 away from the first cylinder body 141 is connected to the discharge hopper 13. In this way, when the discharge hopper 13 is far from the pump truck hopper 23, the first piston rod 142 can be driven to extend, so as to drive one end of the discharge hopper 13 close to the mixer truck body 11 to rotate around the mixer truck body 11, so that the lower end of the discharge hopper 13 can be located directly above the pump truck hopper 23. When the discharge hopper 13 is far from the pump truck hopper 23, the first piston rod 142 can be driven to contract, so as to drive one end of the discharge hopper 13 close to the mixer truck body 11 to rotate in the reverse direction around the mixer truck body 11, so that the lower end of the discharge hopper 13 can be located directly above the pump truck hopper 23.
[0033] In other embodiments provided by the present disclosure, the above-mentioned lifting structure may also be a linear motor, and the output shaft of the linear motor may move in the up and down direction, so as to drive the discharge hopper 13 to move in the up and down direction, so as to adjust the elongation distance of the discharge hopper 13.
[0034] Optionally, as Figure 1 to Figure 2 shown, the mixer truck body 11 may further include a steering mechanism 110. The steering mechanism 110 is used to drive the discharge hopper 13 to turn in the horizontal direction. One end of the steering mechanism 110 is connected to the mixer truck body 11, and the other end of the steering mechanism 110 is connected to the discharge hopper 13. That is to say, the steering mechanism 110 can adjust the position of the discharge hopper 13 in the width direction of the mixer truck 10. In this way, even if there is a certain deviation in the position between the pump truck 20 and the mixer truck 10, the normal feeding of the pump truck hopper 23 can be realized by driving the discharge hopper 13 by the steering mechanism 110, and various discharging working conditions can be adapted.
[0035] Alternatively, the above-mentioned steering mechanism 110 may also be a rotary motor, and the output shaft of the rotary motor is arranged in the vertical direction and connected to the discharge hopper 13. In this way, when the rotary motor rotates, the left and right swing of the discharge hopper 13 can be realized.
[0036] Optionally, as Figure 1 to Figure 2 shown, in an exemplary embodiment provided by the present disclosure, the steering mechanism 110 may include a second hydraulic cylinder 111 and a transmission component 112. The second hydraulic cylinder 111 may include a second cylinder body 1111 and a second piston rod 1112. One end of the second cylinder body 1111 away from the second piston rod 1112 is connected to the mixer truck body 11, and one end of the second piston rod 1112 away from the second cylinder body 1111 is connected to the transmission component 112. The transmission component 112 is connected to the discharge hopper 13. The second piston rod 1112 is used to drive the transmission component 112 to rotate around the vertical rotation axis 11201, so as to drive the discharge hopper 13 to swing around the vertical rotation axis 11201. In this way, when it is necessary to adjust the position of the discharge hopper 13 in the left and right directions, the second hydraulic cylinder 111 moves and drives the second piston rod 1112 to extend and retract, so as to drive the transmission component 112 connected to the second piston rod 1112 to rotate around the above-mentioned vertical rotation axis 11201, and further drive the discharge hopper 13 to rotate synchronously around the vertical rotation axis 11201, so that the discharge hopper 13 can rotate around the end where it is hinged to the mixer truck body 11, so as to adjust the position of the other end of the discharge hopper 13 in the width direction of the mixer truck body 11 to match the position of the pump truck hopper 23.
[0037] The present disclosure does not limit the specific structure of the above-mentioned transmission component 112. For example, in an exemplary embodiment provided by the present disclosure, optionally, as Figure 2As shown, the transmission assembly 112 may include a rotating shaft 1120 connected to the mixer truck body 11 and a gear 1121. The rotating shaft 1120 extends in the vertical direction. The gear 1121 is connected to the rotating shaft 1120. A tooth groove is formed on one side of the second piston rod 1112 close to the gear 1121. The tooth groove extends along the length direction of the piston rod, and the tooth groove meshes with the gear 1121. In this way, when it is necessary to adjust the position of the discharge hopper 13 in the left - right direction, the second piston rod 1112 of the second hydraulic cylinder 111 moves. Since a tooth groove is formed on one side of the second piston rod 1112 close to the gear 1121, the tooth groove extends along the length direction of the piston rod, and the tooth groove meshes with the gear 1121. Thus, during the telescopic process of the second piston rod 1112, the gear 1121 and the rotating shaft 1120 connected to the gear 1121 can be driven to rotate in the vertical direction, thereby driving the discharge hopper 13 to swing around the vertical rotation axis 11201, realizing the adjustment of the position of the discharge hopper 13 in the left - right direction of the mixer truck body 11.
[0038] It should be noted that for the embodiment in which the lifting mechanism 14 is the first hydraulic cylinder, the above - mentioned first piston rod 142 can be hinged to the rotating shaft 1120. In this way, during the process of the second hydraulic cylinder 111 driving the rotating shaft 1120 to rotate, the first hydraulic cylinder can rotate synchronously with the discharge hopper 13. Therefore, it can avoid the situation that the first hydraulic cylinder interferes with the rotation of the discharge hopper 13 during the process of the steering mechanism 110 driving the discharge hopper 13 to rotate.
[0039] In order to improve the measurement accuracy of the above - mentioned material height measuring mechanism 21, in an exemplary embodiment provided by the present disclosure, as Figure 1 to Figure 2 shown, the pump truck hopper 23 may include a hopper body 230 and a mounting block 231. The mounting block 231 is connected to the hopper body 230 and protrudes upward from the hopper body 230. The material height measuring mechanism 21 is arranged on the mounting block 231. Since the material height measuring mechanism 21 is arranged on the mounting block 231, and the mounting block 231 is connected to the hopper body 230 and protrudes upward from the hopper body 230, in this way, the material height measuring mechanism 21 can be in a relatively high position, and has a wider collection field of view during the collection of the material located in the hopper body 230, thus avoiding the problem of being blocked by the accumulated material or the hopper body 230 during the collection process, achieving the purpose of improving the collection accuracy of the material height.
[0040] Optionally, the present disclosure does not limit the specific setting position of the above - mentioned mounting block 231. For example, as Figure 1 to Figure 2As shown, the mounting block 231 can be arranged at the front end of the hopper body 230 (taking the front-rear direction of the concrete pump truck 20 as a reference). Since the mixer truck 10 is generally located behind the concrete pump truck 20 during the discharging process of the mixer truck 10, arranging the mounting block 231 at the front end of the hopper body 230, that is, the mounting hole is located at one end of the hopper body 230 away from the mixer truck 10, can avoid the problem that materials drip on the mounting block 231 during the discharging process, covering the material height measuring mechanism 21, or the problem that the mixer truck body 11 collides with or interferes with the mounting block 231, and improve the stability of the material height measuring mechanism 21 during the measurement process.
[0041] In an exemplary embodiment provided by the present disclosure, the above-mentioned material height measuring mechanism 21 can be an infrared distance sensor. This infrared distance sensor is a measuring device using infrared rays as the medium, and has the advantages of a wide measuring range, a short response time, and a long measuring distance, and can be suitable for various harsh industrial environments.
[0042] Alternatively, in other embodiments provided by the present disclosure, the material height measuring mechanism 21 can also be a liquid level height sensor or a pressure sensor. For the liquid level height sensor, the liquid level height sensor can measure the horizontal height of the materials accumulated in the hopper body 230, thereby avoiding the problem that the materials are too little or overflow from the hopper body 230.
[0043] For the embodiment in which the material height measuring mechanism 21 is a liquid level height sensor, the liquid level height sensor can be an ultrasonic liquid level sensor or an optical liquid level sensor.
[0044] In an exemplary embodiment provided by the present disclosure, the position detection mechanism 15 is an ultrasonic sensor. The ultrasonic sensor is a sensor that can convert ultrasonic signals into electrical signals by using the characteristics of ultrasonic waves. The ultrasonic sensor can be used to detect transparent objects, liquids, any rough, smooth, optically dense materials, and irregular objects, and can accurately sense the change in distance, and has the advantages of high sensitivity, strong penetration, and little influence by the external environment, and can adapt to a variety of discharging environments.
[0045] In order to facilitate the acquisition of the position of the concrete pump truck hopper 23 by the ultrasonic sensor, in an exemplary embodiment provided by the present disclosure, as Figure 1 shown, the acquisition camera of the ultrasonic sensor can be arranged above the discharging hopper 13. On the one hand, when the acquisition camera of the ultrasonic sensor arranged above the discharging hopper 13 acquires the position of the concrete pump truck hopper 23, it will not be blocked or interfered by the discharging hopper 13. On the other hand, since the acquisition camera of the ultrasonic sensor is at a relatively high height, it has a better acquisition field of view and can cover a larger acquisition range.
[0046] Furthermore, the combined system of the concrete pump truck 20 and the mixer truck may further include a buzzer, which can be signal-connected to the controller. When the controller receives abnormal data (such as when the discharge hopper 13 is not set above the hopper 23 of the concrete pump truck, or when problems such as overflow / air suction occur due to too fast or too slow filling), the buzzer vibrates to remind the operator to check the abnormal discharging state.
[0047] It should be noted that the buzzer can be set on the vehicle body 22 of the concrete pump truck or on the vehicle body 11 of the mixer truck, and the present disclosure does not limit this.
[0048] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0049] In addition, it should be noted that, in the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without conflict. To avoid unnecessary repetition, the present disclosure does not separately describe various possible combination methods.
[0050] In addition, any combination can be made between different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
