[0050] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0051] In the present disclosure, unless otherwise stated, terms such as “first”, “second”, and “first” are used merely to distinguish one element from another, and do not have any order or importance.

[0052] like Figures 1 to 5 As shown, the present disclosure provides a detection system for detecting a fluid pumping device, which includes a driving device 1, a fluid damping tube 2, a first detection element (not shown), and a first mounting bracket 9. The driving device 1 is used to drive the first pumping mechanism 101 and the second pumping mechanism 102 of the fluid pumping device 10 to alternately suck and push the fluid material 20; the first mounting bracket 9 is provided with a plurality of mounting points 91 for mounting a plurality of different types of fluid pumping devices 10 in a one-to-one correspondence; the fluid damping tube 2 is used to transport the fluid material 20 and can apply resistance to the fluid material 20 flowing therein; the feed port of the fluid damping tube 2 is used to be detachably connected to the S tube 103 of the fluid pumping device 10, and the discharge port of the fluid damping tube 2 is used to be detachably connected to the hopper 104 of the fluid pumping device 10; the first detection element is used to detect the volume of the fluid material 20 flowing into the hopper 104 through the discharge port of the fluid damping tube 2.

[0053] In the above technical solution, first, by setting a fluid damping tube 2, when the fluid material 20 flows in the fluid damping tube 2, it will be subject to the resistance applied by the fluid damping tube 2. The reason for applying resistance is to make the pumping resistance of the fluid pumping device 10 being tested reach the resistance encountered during actual operation, so as to achieve the purpose of simulating the actual working conditions of the fluid pumping device 10.

[0054] Secondly, the feed port and the discharge port of the fluid damping tube 2 are detachably connected to the S tube 103 and the hopper 104 of the fluid pumping device 10 respectively. In the process of the driving device 1 driving the fluid pumping device 10 to pump the fluid material 20, the fluid material 20 will be circulated and pumped in the fluid pumping device 10 and the fluid damping tube 2. There is no need to configure the same volume of fluid material 20 as in the actual working conditions, which greatly reduces the use of simulated fluid material 20 and reduces the test cost. The purpose of detection can be achieved by recycling the fluid material 20.

[0055] In addition, by setting up the first mounting bracket 9, the stability of the fluid pumping device 10 during the detection process can be ensured, and damage to the fluid pumping device 10 can be avoided; a plurality of mounting points 91 are provided on the first mounting bracket 9 for one-to-one installation of a plurality of different types of fluid pumping devices 10, so as to carry out corresponding tests of different forms and improve the practicality of the first mounting bracket 9.

[0056] In addition, by setting up a first detection element, and the first detection element can detect the volume of the fluid material 20 flowing into the hopper 104 through the outlet of the fluid damping tube 2, the first detection element can detect the total volume of the fluid material 20 pumped by the fluid pumping device 10 in real time, using the formula: suction efficiency = mixer truck feeding volume / (number of reversals*theoretical volume per reversal)*100%. The operator can calculate the suction efficiency of the fluid pumping device 10 being tested based on the volume of the fluid material 20 detected by the first detection element (i.e., the mixer truck feeding volume), the number of alternating suction and pushing operations (total number of reversals) performed by the first pumping mechanism 101 and the second pumping mechanism 102 of the fluid pumping device 10, and the theoretical pushing volume of the pumping mechanism in a single time (theoretical volume per reversal), thereby accurately and efficiently testing the suction performance of the fluid pumping device 10 being tested.

[0057] It should be noted that the specific structure of the fluid pumping device 10 can be referred to Figure 6As shown, the components of the fluid pumping device 10 include the above-mentioned first pumping mechanism 101, the second pumping mechanism 102, the S tube 103, the hopper 104, the swing valve mechanism 105, the stirring mechanism 106, and the first pumping mechanism 101 includes a first master oil cylinder 1011, a first delivery cylinder 1012 and a first concrete piston 1013, and the second pumping mechanism 102 includes a second master oil cylinder 1021, a second delivery cylinder 1022 and a second concrete piston 1023.

[0058] The working principle of the fluid pumping device 10 is as follows: driven by high-pressure hydraulic oil, the two piston rods in the first master cylinder 1011 and the second master cylinder 1021 work alternately, pushing and pulling the first concrete piston 1013 and the second concrete piston 1023 connected thereto to move in the first delivery cylinder 1012 and the second delivery cylinder 1022 respectively, and the fluid material 20 in the hopper 104 is continuously sucked in and discharged in the first delivery cylinder 1012 and the second delivery cylinder 1022, and the swing valve mechanism 105 swings back and forth, pushing the S tube 103 to rotate, transporting the fluid material 20 in the first delivery cylinder 1012 and the second delivery cylinder 1022, and continuously transporting it to the work site along the S tube 103 through the delivery pipeline.

[0059] In an alternative embodiment, referring to Figure 1 As shown, the fluid damping tube 2 includes multiple sections of curved tubes 21, which are connected end to end to form a serpentine shape. This increases the resistance encountered by the fluid material 20 during flow, so that the pumping resistance encountered by the fluid pumping device 10 under test reaches the resistance encountered during actual operation. The more curved tubes 21 there are, the greater the resistance generated. The pumping resistance encountered by the fluid pumping device 10 can be adjusted by adjusting the number of curved tubes 21 set. In addition, the pumping resistance generated by a 90-degree curved tube 21 is approximately equal to the pumping resistance generated by four 3000 mm long straight tubes. Compared with the method of setting long straight tubes, the method of setting curved tubes 21 can also shorten the length of the fluid damping tube 2.

[0060] However, the present disclosure does not limit the specific structure and shape of the fluid damping tube 2 , as long as it can apply a certain resistance to the fluid material 20 .

[0061] Optionally, refer to Figure 1 As shown, the detection system also includes a feed pipe 3, a return pipe 4 and a cooling trough 5 provided with a cooling medium; the feed port of the feed pipe 3 is used to be detachably connected to the S pipe 103, the discharge port of the feed pipe 3 is used to be connected to the feed port of the fluid damping tube 2, the discharge port of the fluid damping tube 2 is used to be connected to the feed port of the return pipe 4, and the discharge port of the return pipe 4 is used to be detachably connected to the hopper 104; at least the fluid damping tube 2 among the feed pipe 3, the fluid damping tube 2 and the return pipe 4 is arranged in the cooling trough 5.

[0062] In this embodiment, firstly, by providing the feed pipe 3, the fluid material 20 can be easily fed into the fluid damping tube 2 through the feed pipe 3, thereby avoiding the problem of blockage at the outlet of the S-tube 103 caused by the direct connection between the fluid damping tube 2 and the S-tube 103. Secondly, by providing the return pipe 4, the fluid material 20 can be easily fed into the hopper 104 through the return pipe 4, thereby avoiding the problem of blockage at the feed inlet of the hopper 104 caused by the direct connection between the fluid damping tube 2 and the hopper 104, thereby ensuring the normal circulation and transportation of the fluid material 20. In addition, during the process of circulating the fluid material 20, the heat generated by the pumping cannot be effectively discharged and is continuously generated in the feed pipe 3, the fluid damping tube 2, and the return pipe 4. This heat can affect the normal proportioning of the fluid material 20. For example, the fluid material 20 is constructed as concrete, which affects the mix ratio and slump of the simulated concrete; and by setting a cooling tank 5 with a cooling medium, and setting at least the fluid damping tube 2 among the feed pipe 3, the fluid damping tube 2 and the return pipe 4 in the cooling tank 5, the heat in at least the fluid damping tube 2 can be dissipated into the cooling medium in the cooling tank 5, thereby ensuring the grading requirements of the fluid material 20, extending the service life of the fluid material 20, and allowing the circulating pumping to be carried out under normal working conditions, which complies with the normal wear of the wearing parts of the fluid pumping device 10.

[0063] Optionally, cooling water is provided in the cooling tank 5 , and the cooling water can be maintained within a certain temperature range. When the temperature is higher than a preset value, cold water will be automatically added to the cooling tank 5 .

[0064] In one embodiment, reference Figure 1 As shown, the detection system also includes a metering container 6, the discharge port of the return pipe 4 is used to communicate with the feed port of the metering container 6, the discharge port of the metering container 6 is used to be detachably connected to the hopper 104, and the first detection element is arranged at the feed port and / or discharge port of the metering container 6.

[0065] In this embodiment, the provision of the metering container 6 facilitates the transitional storage of the fluid material 20, thereby increasing the overall volume of the fluid material 20 and preventing the inability to continuously circulate and pump the fluid material 20 due to insufficient fluid material 20. Furthermore, the provision of the metering container 6 facilitates the provision of a first detection element to detect the volume of the fluid material 20 flowing into the hopper 104. For example, the first detection element may be configured as a flow meter, but the present disclosure does not limit the specific type of the first detection element.

[0066] Optionally, the detection system may further include a controller (not shown), the driving device 1 and the first detection element are electrically connected to the controller, and the controller is used to be electrically connected to the fluid pumping device 10; the controller is configured to: be able to be used to obtain the suction efficiency of the fluid pumping device 10 based on the number of alternating suction and pushing times of the first pumping mechanism 101 and the second pumping mechanism 102, the single theoretical pushing volume of the pumping mechanism, and the volume of the fluid material 20 measured by the first detection element.

[0067] That is, in this embodiment, the controller can be provided to automatically detect the suction efficiency of the fluid pumping device 10 being detected, without the need for manual detection, and the degree of automation is high.

[0068] In addition, in order to enable the inspector to intuitively see the suction efficiency of the fluid pumping device 10 obtained through inspection, the inspection system may further include a display device (not shown), which is electrically connected to the controller to display the suction efficiency of the fluid pumping device 10 in real time. For example, the display device may be constructed as a display screen, but the present disclosure does not limit the specific structural type of the display device.

[0069] Specifically, refer to Figure 1 and Figure 6 As shown, in combination with the specific structure of the fluid pumping device 10, during the process of testing the suction efficiency of the fluid pumping device 10, the S tube 103 is connected to the first delivery cylinder 1012 by using the reversing of the swing valve mechanism 105, and the first master cylinder 1011 pushes the first concrete piston 1013 to push the fluid material 20 in the first delivery cylinder 1012 into the S tube 103, and enters the fluid damping tube 2 through the feed pipe 3. The fluid material 20 continues to move along the direction of the arrow to the return pipe 4, and then returns to the hopper 104 through the metering container 6; at the same time, the second master cylinder 1021 drives the second concrete piston 1023 to move backward, thereby sucking the fluid material in the hopper 104 into the second delivery cylinder 1022. When the second concrete piston 1023 retreats to the sensing position of the water tank 107, the swing valve mechanism 105 starts to reverse, and the S tube 103 is connected to the second delivery cylinder 1022, and a new pumping cycle begins. The pumping reversing of the fluid pumping device 10 works synchronously with the first detection element in the metering container 6. By comparing the theoretical volume with the actual volume, the pumping efficiency is continuously fed back to the above-mentioned display device. After the pumping is completed, the average suction efficiency can be calculated to improve accuracy.

[0070] Reference Figure 2As shown, the detection system also includes a pressure regulating member 7 and a second detection element 8. The pressure regulating member 7 is used to be detachably arranged at the outlet of the S-tube 103 and can be used to change the pressure at the outlet of the S-tube 103 by adjusting its pressure parameter to a target pressure value. The second detection element 8 is used to detect the pressure at the outlet of the S-tube 103, and when the pressure regulating member 7 is installed at the outlet of the S-tube 103, the fluid damping tube 2 is not connected to the S-tube 103.

[0071] In this embodiment, when testing the outlet pressure of the fluid pumping device 10, it is necessary to first remove the fluid damping tube 2 from the S tube 103, that is, the rear end of the S tube 103 is not connected to the delivery pipe. After the fluid damping tube 2 is removed, the pressure regulating member 7 is installed at the outlet of the S tube 103. The testing personnel can set the pressure parameter of the pressure regulating member 7 to the target pressure value. After the setting is completed, the testing personnel operates the driving device 1 to drive the fluid pumping device 10 to pump water. The second detection element 8 detects the pressure at the outlet of the S tube 103. The testing personnel judges the sealing of the fluid pumping device 10 by comparing whether the pressure value detected by the second detection element 8 is approximately equal to the target pressure value. If the pressure value detected by the second detection element 8 is much smaller than the target pressure value, it can be judged that the fluid pumping device 10 being tested has a leakage problem.

[0072] Optionally, the detection system may further include a controller (not shown), which is electrically connected to the pressure regulating member 7 and the second detection element 8. The controller is configured to compare the pressure value detected by the second detection element 8 with a target pressure value to determine whether the fluid pumping device 10 is leaking. Specifically, when the pressure value detected by the second detection element 8 is less than the target pressure value and the difference is greater than a first threshold value, the fluid pumping device 10 is determined to be leaking. In this embodiment, by providing a controller, the automation level of the detection system can be effectively improved, and the detected fluid pumping device 10 can be automatically determined to be leaking.

[0073] In one embodiment, reference Figure 2 As shown, pressure regulating member 7 may include a pressure regulating valve assembly equipped with the aforementioned second detection element 8. When fluid pumping device 10 is pumping water, adjusting the adjustment handle of the pressure regulating valve assembly increases or decreases the water pressure within fluid pumping device 10 depending on the position of the adjustment handle. Second detection element 8 detects the pressure at the outlet of S-tube 103. This pressure can be transmitted to the controller, which in turn transmits the pressure signal to the GPS terminal. Finally, the pressure at the outlet of S-tube 103 can be viewed on the connected vehicle network. This eliminates the need for intermediate calculations and allows for direct detection, improving efficiency and accuracy.

[0074] Optionally, refer to Figure 4 and Figure 5 As shown, the above-mentioned first mounting bracket 9 includes a base plate 92 and a plurality of support columns 93 arranged on the base plate 92, wherein a mounting plate 90 is provided on the top of one of the support columns 93, and a plurality of the above-mentioned mounting points 91 are provided on the mounting plate 90. The plurality of mounting points 91 can be constructed as a plurality of mounting holes, and the plurality of mounting holes can be used to mount a plurality of different types of fluid pumping devices 10 in a one-to-one correspondence through fasteners. However, the present disclosure does not limit the specific structural form of the plurality of mounting points 91. In other embodiments, the plurality of mounting points 91 can also be constructed as a plurality of clip-on structures, etc.

[0075] In addition, the first mounting bracket 9 is also provided with other components adapted to the fluid pumping device 10 to ensure the normal operation of the fluid pumping device 10 .

[0076] Reference Figure 3 As shown, the drive device 1 includes a power source 11, a power distribution unit 12, a hydraulic drive unit 13, a second mounting bracket 14 and a hydraulic oil tank 15 for supplying hydraulic oil to the hydraulic drive unit 13. The power source 11, the power distribution unit 12, the hydraulic drive unit 13 and the hydraulic oil tank 15 are all arranged on the second mounting bracket 14; the power distribution unit 12 is transmission-connected to the power source 11 and is used to distribute the power generated by the power source 11 to meet the power requirements under different working conditions; the hydraulic drive unit 13 is transmission-connected to the power distribution unit 12 for converting power into hydraulic energy; the hydraulic drive unit 13 is used to deliver hydraulic oil with hydraulic energy to the fluid pumping device 10.

[0077] In this embodiment, by changing the specific type of the power source 11, the rationality of the power source 11 can be tested, the optimal power match of the fluid pumping device 10 being tested can be determined, power waste can be reduced, and the pumping efficiency can be optimized; by testing the power distribution unit 12 with different power distribution schemes, a power distribution scheme that is most suitable for the fluid pumping device 10 being tested can be tested. For example, by assembling and combining different forms of gears in the transfer case, the power distribution of the new transfer case and whether the speed ratio is reasonably designed can be verified, and an optimal gear distribution ratio can be debugged; thereby providing an experimental basis for the preliminary research of supporting products of the fluid pumping device 10.

[0078] Optionally, the hydraulic drive unit 13 may be composed of a main oil pump, a constant pressure pump, a gear pump, etc., to convert mechanical energy into hydraulic energy, thereby achieving stable driving of the fluid pumping device 10 .

[0079] The detection system of the present disclosure further includes a hydraulic pipeline (not shown), which is used to connect the hydraulic drive unit and the fluid pumping device.

[0080] In addition, in addition to being able to realize the above-mentioned detection functions, the detection system disclosed in the present invention can also simulate the wear of components such as the eyeglass plate, cutting ring, and concrete piston of the fluid pumping device 10 under normal working conditions during the circulation pumping of the fluid material 20, thereby achieving the effect of verifying the service life of components such as the eyeglass plate, cutting ring, and concrete piston of the fluid pumping device 10, and continuously performing cyclic detection can significantly shorten the verification cycle and gain time for new products to be put on the market.

[0081] In addition, the inspectors can also attach strain gauges to different parts of the fluid pumping device 10 to measure the stress in the corresponding parts, providing a theoretical basis for the performance, stability, and lightweight of the fluid pumping device 10.
