Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pumping machinery, and particularly relates to a pipe laying test system. Background Art

[0002] In the field of concrete pumping machinery, pumping pressure, pumping efficiency, etc. are key performances. It is often necessary to simultaneously analyze the advantages and disadvantages of the pumping performances of multiple pipe laying schemes to provide a basis for the pipeline installation of the final production vehicle. Currently, there are mainly two test schemes:

[0003] (1) Use the same pumping system and conduct the test verification of one pipe laying scheme each time.

[0004] Although this scheme can avoid the differences of the pumping systems, it also has two disadvantages: 1. It ignores the differences of the concrete itself. Even for the same formula of concrete, there may be certain rheological property differences in the concrete prepared at different times, which will cause errors in the measurement results and affect the selection of the optimal scheme. 2. Only one concrete test can be carried out at a time. The single concrete test process (including the processes of concrete preparation, measurement system installation, pipeline installation, pipeline cleaning, etc.) consumes a large amount of experimental resources, resulting in waste of manpower and experimental resources.

[0005] (2) Use multiple pumping systems and conduct the test verification of multiple pipe laying schemes simultaneously.

[0006] Although this scheme improves the test efficiency, it also has the following problems: 1. It ignores the differences of the pumping systems. Even for the same model of pumping systems, there will be differences, which will lead to misjudgment of the measurement results and affect the selection of the optimal scheme. 2. If the same batch of concrete is used to verify different pipe laying schemes respectively, it will cause the mixer truck to transfer between different test sites, which will invisibly increase the test time. Since concrete has strong thixotropy, the rheological properties of concrete may change with the extension of time, which will lead to inaccurate test results. If different batches of concrete are used to verify different pipe laying schemes respectively, it will also lead to errors in the measurement results caused by the differences of the concrete itself. 3. Using the pipe laying schemes of multiple pumping systems simultaneously requires a large test site and a large amount of test resources, which will invisibly increase the test cost.

[0052] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0053] The following describes the pipe laying test system of the present invention with reference to the drawings.

[0054] As Figure 1 and Figure 2 shown, the present invention provides a pipe laying test system, wherein the pipe laying test system includes:

[0055] A pumping device 100 for pumping concrete;

[0056] A shunting device, including a shunting box body 300, a shunting pipe 400 and a swing driving mechanism 500. The shunting box body 300 has a first side plate 310 and a second side plate 320 arranged oppositely. The first end of the shunting pipe 400 is rotatably arranged on the first side plate 310 and is docked with the pumping device 100. At least two first docking ports 341 for communicating with the second end of the shunting pipe 400 are formed on the second side plate 320. The outer ends of the at least two first docking ports 341 are respectively used for docking with at least two test pipelines 700 one by one. The swing driving mechanism 500 is arranged on the shunting box body 300 and is used for driving the first end of the shunting pipe 400 to rotate while driving the second end to swing to communicate with different first docking ports 341;

[0057] A verification device, including a pressure sensor 200 for detecting the pressure loss value of the test pipeline 700.

[0058] When using the above pipeline laying test system, when verifying the pumping performance of the pipeline laying scheme for different test pipelines 700, different test pipelines 700 can be externally connected to different first pairs of interfaces 341, and by controlling the swing drive mechanism 500 to switch the second ends of the shunt pipes 400 to communicate with different first pairs of interfaces 341 respectively, the concrete pumped by the same pumping device 100 can be pumped into different test pipelines 700. The pressure sensors 200 on the test pipelines 700 can detect the pressure loss values characterizing the pumping performance, thereby completing the verification of the pumping performance of different pipeline laying schemes. Compared with the two test schemes in the prior art, using one pumping device 100 can complete the verification of the pumping performance of different pipeline laying schemes, which can not only avoid the influence of the differences of different pumping devices 100 on the measurement results, but also ensure that different tests are carried out under the same material condition, the same time period and the same gear as much as possible, reduce the influence of the differences of the concrete itself on the measurement results, and at the same time play the role of reducing the floor area of the test site, reducing the test cost and improving the test efficiency.

[0059] Specifically, the pumping device 100 is a unit for realizing continuous concrete pumping, and realizes a periodic movement process of one suction and one push through two periodically actuated oil cylinders. Combining with the periodic swing of the shunt device, continuous pumping is realized.

[0060] In the embodiment of the present invention, pressure sensors 200 are respectively installed at the inlet end and the outlet end of each test pipeline 700. By detecting the pressure difference between two measuring points at the inlet end and the outlet end of each test pipeline 700, the pressure loss value of each test pipeline 700 can be determined. Finally, by comparing the magnitudes of the pressure loss values of different test pipelines 700, the superiority and inferiority of the pumping pressure loss of different pipeline laying schemes can be determined.

[0061] See Figures 2 to 4, in the embodiment of the present utility model, a connection block 410 is provided on the outer side of the second end of the shunt pipe 400. The swing drive mechanism 500 includes a swing drive member 510 and a swing shaft assembly. The swing shaft assembly passes through the second side plate 320 from outside to inside and is inserted and connected to the connection block 410. The number of swing drive members 510 is two. Both of the two swing drive members 510 are provided on the outer side of the second side plate 320 and are respectively arranged on opposite sides of the swing shaft assembly. The telescopic drive ends of the two swing drive members 510 are respectively drivingly connected to the swing shaft assembly. That is, the swing drive mechanism 500 is arranged to be drivingly connected to the second end of the shunt pipe 400, and directly drives the second end of the shunt pipe 400 to swing and switch between different first pair of interfaces 341. The first end of the shunt pipe 400 rotates on the first side plate 310 following the swing movement of the second end. Compared with the solution that the swing drive mechanism 500 directly drives the first end of the shunt pipe 400 to rotate, the solution where the second end follows the swing can improve the reliability of the connection between the second end of the shunt pipe 400 and the first pair of interfaces 341. At the same time, using two swing drive members 510 to drive the second end of the shunt pipe 400 to swing through telescopic drive movement can further ensure the reliability of the swing movement.

[0062] Specifically, for the two swing drive members 510, when one swing drive member 510 extends, the other swing drive member 510 retracts, performing an alternating movement, which is particularly suitable for switching between only two first pair of interfaces 341. Of course, the present utility model is not limited to this. The extension and retraction lengths of the two swing drive members can be designed so that the second end of the shunt pipe 400 can switch between more than two first pair of interfaces 341. More specifically, the swing drive member 510 includes, but is not limited to, a swing oil cylinder, and can also be a swing electric cylinder, etc.

[0063] In the embodiment of the present utility model, the swing shaft assembly includes a shaft body 520 and a swing handle head 530. The swing handle head 530 includes a drive connection portion 531 and a shaft mounting connection portion 532 arranged in sequence from top to bottom. The shaft body 520 is inserted through the second side plate 320 and is located above all the first pair of interfaces 341. The inner and outer ends of the shaft body 520 are respectively inserted into the connection block 410 and the shaft mounting connection portion 532 in a one-to-one correspondence and are both connected through a key structure. The telescopic drive ends of the two swing drive members 510 are respectively inserted into the drive connection portion 531 from the left and right sides of the drive connection portion 531. That is, the swing shaft assembly is arranged as a separately provided shaft body 520 and swing handle head 530, so as to facilitate the disassembly and assembly between the swing shaft assembly and the connection block 410 and the two swing drive members 510, and the shaft body 520 and the swing handle head 530 can be separately repaired and replaced.

[0064] Furthermore, a first connecting hole for inserting the shaft body 520 is provided on the side of the connecting block 410 that is arranged toward the second side plate 320, and the shaft body 520 is key-connected to the connecting block 410 via a flat key structure in the first connecting hole, and a second connecting hole for inserting the shaft body 520 is provided on the shaft-mounted connecting portion 532 of the swinging handle head 530, and the shaft body 520 is key-connected to the shaft-mounted connecting portion 532 via a flat key structure in the second connecting hole.

[0065] See also Figure 2 and Figure 4 In the embodiment of the utility model, a mounting seat 330 is provided on the diverter box 300, and the mounting seat 330 includes a mounting horizontal plate 331 and a mounting vertical plate 332, and the swing driving member 510 is hingedly mounted on the side of the mounting vertical plate 332 facing the first docking port 341. That is, one end of the mounting horizontal plate 331 extending toward the first docking port 341 can form a protective space for the swing driving member 510 to be installed with the mounting vertical plate 332, and the other end of the mounting horizontal plate 331 continues to extend along the circumference of the diverter box 300, so as to play a role in strengthening the structure on the diverter box 300. It should be particularly noted that the outer side of at least two first docking ports 341 refers to the two end sides where all the first docking ports 341 are arranged in sequence. Specifically, the number of mounting seats 330 can be two, and the two mounting seats 330 are respectively arranged at the aforementioned two end sides, and the two swing driving members 510 are respectively arranged on the two mounting seats 330 in a one-to-one correspondence.

[0066] like Figure 3 As shown, in the embodiment of the utility model, a reinforcing rib plate 420 is provided between the shunt pipe 400 and the connecting block 410. The additional reinforcing rib plate 420 can play a role in reinforcing the connecting block 410. Specifically, the reinforcing rib plate 420 is provided on a side of the connecting block 410 away from the second side plate 320.

[0067] Please see again Figures 2 to 4In the embodiment of the utility model, the flow dividing box 300 includes a box body, a pipe sleeve mounting plate 340 and a wear plate 350. The box body has a first side plate 310 and a second side plate 320. The second side plate 320 is provided with a first mounting port. The pipe sleeve mounting plate 340 is detachably arranged on the outer side of the second side plate 320 corresponding to the first mounting port, and forms at least two first docking ports 341. The wear plate 350 is detachably arranged on the inner side of the second side plate 320 corresponding to the first mounting port, and forms at least two second docking ports 351 that are in one-to-one communication with at least two first docking ports 341. The second end of the flow dividing pipe 400 abuts against the wear plate 350, and can be in communication with different second docking ports 351 under the drive of the swing driving mechanism 500. The addition of the pipe sleeve mounting plate 340 on the box body is convenient for processing, manufacturing, repairing and replacing the first docking port 341, and is convenient for changing the type to adapt to test pipelines 700 of different sizes. The addition of the wear-resistant plate 350 can increase the service life of the flow dividing device. The wear-resistant material on the surface of the wear-resistant plate 350 can improve the wear resistance of the end surface caused by switching back and forth. The wear-resistant material can be high manganese steel, etc. Specifically, the pipe sleeve mounting plate 340 and the wear-resistant plate 350 can be detachably connected to the second side plate 320 by fasteners, and the two can also be detachably connected by fasteners.

[0068] In the embodiment of the utility model, a second installation opening is provided on the first side plate 310, and the flow diversion box 300 further includes a butt joint pipe assembly 360, which is arranged through the second installation opening and fixedly connected to the first side plate 310, and the outer end of the butt joint pipe assembly 360 is butt jointed with the pumping device 100, and the inner end of the butt joint pipe assembly 360 can be rotatably mounted on the first end of the flow diversion pipe 400. By adding the butt joint pipe assembly 360, the pumping device 100 and the first end of the flow diversion pipe 400 can be butt jointed, and the first end of the flow diversion pipe 400 can be rotatably assembled, and it is easy to disassemble, repair and replace. Specifically, the outer end of the butt joint pipe assembly 360 is provided with a flange body that is butt jointed with the pumping device 100.

[0069] In the embodiment of the utility model, the shunt tube 400 is S-shaped, the axis lines of at least two first docking ports 341 are arranged on the first circumference, and the rotation axis of the first end of the shunt tube 400 is arranged colinearly with the center line of the first circumference, that is, the swing of the second end of the shunt tube 400 is along the first circumferential direction, which is convenient for design and production. Figure 5 As shown, the rotation axis of the first end of the shunt tube 400 is marked as C, and the axis lines of the two first docking ports 341 are marked as A and B respectively.

[0070] like Figure 1 and Figure 6As shown, in the embodiment of the present utility model, the pipe laying test system further includes a support device 600. The support device 600 includes a counterweight 610, a connecting plate assembly 620, and a hoop 630. The connecting plate assembly 620 is arranged on the counterweight 610 with adjustable height. The hoop 630 can clamp the test pipeline 700 to the upper end of the connecting plate assembly 620. The addition of the support device 600 can realize the suspended support of the test pipeline 700 and avoid the phenomenon of pipeline shaking during the pumping test. At the same time, setting the height of the connecting plate assembly 620 to be adjustable enables adjustment according to the required suspended height at different positions of the test pipeline 700, achieving the purpose of improving versatility.

[0071] Specifically, along the length direction of each test pipeline 700, multiple support devices 600 can be arranged at intervals in sequence, and the height dimensions of the counterweights 610 of the multiple support devices 600 can be set differently. The counterweight 610 can be a square block made of cement, and its function is to fix the test pipeline 700 to the support device 600 by its own gravity and limit the pipeline displacement caused by the periodic impact during the pumping process.

[0072] See Figure 6 and Figure 7 In the embodiment of the present utility model, the connecting plate assembly 620 includes an adjusting cross plate 622 and a lifting plate group. The adjusting cross plate 622 is arranged on the counterweight 610. The lower end of the lifting plate group is installed on the adjusting cross plate 622 with adjustable horizontal position, and the lifting plate group is set with adjustable height. The hoop 630 can clamp the test pipeline 700 to the upper end of the lifting plate group. By adding the adjusting cross plate 622, the horizontal position of the lifting plate group can be adjusted, so that when the counterweight 610 has been placed, there is no need to reposition the counterweight 610, and the position of the lifting plate group on the adjusting cross plate 622 can be finely adjusted.

[0073] In the embodiment of the present utility model, an installation backing plate 625 is provided at the upper end of the lifting plate group. The installation backing plate 625 is set with adjustable angle. The hoop 630 can clamp the test pipeline 700 to the installation backing plate 625. By adding the installation backing plate 625, it can adapt to the different support angle requirements of the test pipeline 700. Specifically, the installation backing plate 625 includes a backing plate body and two ear plate parts arranged on the lower side of the backing plate body. The two ear plate parts are arranged at intervals relative to each other. The upper end of the lifting plate group extends between the two ear plate parts and is connected in series by bolts.

[0074] In the embodiment of the present utility model, the counterweight 610 includes a block body and a support vertical plate 621 embedded in the block body. The adjustment horizontal plate 622 is arranged on the support vertical plate 621, and the four sides of the adjustment horizontal plate 622 extend out of the support vertical plate 621. The addition of the support vertical plate 621 facilitates the connection between the adjustment horizontal plate 622 and the counterweight 610 on the one hand. On the other hand, since the support vertical plate 621 and the adjustment horizontal plate 622 are in a T shape, it can provide a loading position for a forklift-like lifting and moving device for the entire support device 600. Fork the support vertical plate 621 below the adjustment horizontal plate 622 and apply an upward lifting force to the adjustment horizontal plate 622, and the position of the support device 600 can be moved, which is convenient to meet the support requirements of the test pipeline 700 at different positions.

[0075] In the embodiment of the present utility model, two columns of first position adjustment holes 626 are formed in the adjustment horizontal plate 622. Specifically, the first position adjustment holes 626 can be waist-shaped holes. And in one column of waist-shaped holes, there can be one waist-shaped hole or multiple waist-shaped holes. Second position adjustment holes are formed at the four corner positions at the lower end of the lifting plate group. The distance between the two columns of first position adjustment holes 626 is set to be the same as the distance between any two adjacent corner position second position adjustment holes. The lower end of the lifting plate group is horizontally position-adjustably installed on the adjustment horizontal plate 622 through threaded fasteners passing through the second position adjustment holes and the first position adjustment holes 626. Since the distance between the two columns of first position adjustment holes 626 is set to be the same as the distance between any two adjacent corner position second position adjustment holes, the placement direction of the lifting plate group can also be adjusted on the adjustment horizontal plate 622.

[0076] In the embodiment of the present utility model, the lifting plate group includes a fixed vertical plate 623 and a lifting vertical plate 624.
