Description

Technical Field

[0001] The utility model relates to the technical field of pressure detection, and more specifically, to a pressure testing device for raw materials of a water conservancy project. Background Art

[0002] Water conservancy engineering mainly studies the basic knowledge and skills in engineering hydrology, water conservancy engineering surveying, water conservancy reinforced concrete, hydraulic structures, engineering drawing, etc., and carries out engineering planning and design, on-site construction, engineering budgeting, and water conservancy equipment maintenance and repair in the field of water conservancy engineering.

[0003] Most of the existing pressure testing devices for raw materials of water conservancy projects use hydraulic rods to apply pressure to the surface of a concrete test block that has been cast in advance, and then use pressure sensors to record data to achieve the purpose of pressure testing of the concrete test block.

[0004] However, in the prior art, the concrete test block is directly placed on a load-bearing platform for pressure testing. Since there is no limiting structure associated with the concrete test block, the concrete test block has poor stability during the pressure test and is prone to positional displacement, which affects the normal progress of the pressure test. At the same time, for heavier concrete test blocks, it is inconvenient to load the concrete test block before the test and unload the concrete test block after the test, which reduces the efficiency of the pressure test.

[0035] A high-pressure air pump 37 electrically connected to the output end of the controller 25 is fixed to the side of the U-shaped seat 3; an air supply pipe 38 is provided at the output end of the high-pressure air pump 37; the ends of the air supply pipe 38 are symmetrically connected to branch pipes 39; the bottom surface of the detection frame 9 is located on both sides of the shaft sleeve 15 and symmetrically fixed with air supply boxes 40; one side of the air supply box 40 is connected to an air intake pipe 41; the two air intake pipes 41 are connected to the corresponding branch pipes 39 through a hose; a plurality of exhaust ports 42 connected to the air supply boxes 40 are evenly opened on the inner bottom surface of the detection frame 9; and a filter is provided at the end of the exhaust port 42.

[0036] A specific application of this embodiment is:

[0037] First, place the concrete test block 6 on the U-shaped seat 3 near the feed port 12, so that the concrete test block 6 is placed on the corresponding first transmission roller 5. In the initial state, the detection frame 9 is in a flat state, and its frame opening is aligned with the feed port 12. The corresponding baffle 51 supports the detection frame 9 in the flat state. Push the concrete test block 6 to slide along the inner wall of the U-shaped seat 3 through the feed port 12 and then slide into the detection frame 9. The concrete test block 6 is placed between the two opposite second transmission rollers 11 inside the detection frame 9, and continue to push the concrete test block 6 to slide into the detection frame 9.

[0038] The servo motor 20 is controlled to start and drive the driving gear 21 to rotate 90° counterclockwise, thereby driving the driven gear 19 together with the connecting shaft 17 and the rotating shaft 8 fixedly installed at the end of the connecting shaft 17 to rotate 90° clockwise synchronously, so that the detection frame 9 rotates to be vertical to the ground, completing the loading and limiting of the concrete test block 6.

[0039] Since the two screw rods 33 are fixedly connected by the connecting rod 32, the two screw rods 33 have opposite screw directions. By rotating the screw rod 33 at one end, the two U-shaped frames 34 are driven to slide synchronously and close together, so that the corresponding support seats 36 slide along the bottom surface of the detection frame 9, thereby supporting and protecting the detection frame 9, thereby preventing the detection frame 9 from swinging during the pressure test of the concrete test block 6, thereby damaging related gears and affecting the use.

[0040] The hydraulic cylinder 22 is controlled to start and extend, thereby driving the pressure plate 23 to slide and descend along the inner wall of the detection frame 9, squeezing the concrete test block 6, and the pressure sensor 24 sends a signal to the controller 25. The controller 25 transmits the received pressure value to the display screen 26, and then uses the display screen 26 to record it to complete the pressure test of the concrete test block 6.

[0041] During the sliding descent of the pressing plate 23, the two L-shaped plates 29 are driven to slide and descend along the top of the U-shaped plate 2, thereby improving the working stability of the pressing plate 23. At the same time, during the descent of the pressing plate 23, the limit rod 30 is slidably inserted into the sliding hole 28, thereby further improving the stability of the detection frame 9.

[0042] Control valves are provided on the branch pipe 39 and the ear tube 43. After the pressure test is completed, the servo motor 20 is controlled to start to drive the driving gear 21 to continue to rotate counterclockwise by 90 degrees, thereby driving the detection frame 9 to rotate clockwise by 90 degrees, so that the frame opening is aligned with the discharge port 13. At this time, the detection frame 9 is in a flat state, and the corresponding baffle 51 supports the detection frame 9 in the flat state. The high-pressure air pump 37 is controlled to start, and the control valve on the branch pipe 39 is controlled to open (the control valve on the ear tube 43 is closed). The compressed air enters the corresponding air delivery box 40 through the branch pipe 39, the corresponding hose, and the air inlet pipe 41 in turn, and is discharged through each group of exhaust ports 42 to push the concrete test block 6, so that the concrete test block 6 after the test is discharged along the second transmission roller 11 between the inner walls of the detection frame 9, and the unloading of the concrete test block 6 is completed.

[0043] For example 3, please refer to Figure 1-6 , the third embodiment makes the following improvements on the basis of the second embodiment. Specifically, an ear tube 43 is provided on the side surface of the gas delivery pipe 38 near its end; a sliding cavity 44 connected to the feed port 12 is provided inside the U-shaped plate 2; an ear seat 31 is fixed to the inner wall of the U-shaped plate 2; a screw 45 is rotatably provided through the top of the ear seat 31; a lifting frame 46 that is slidably provided on the inner wall of the sliding cavity 44 and is threadably matched with the screw 45; a scraper 47 is fixed to the bottom surface of the lifting frame 46; an extension plate 48 is fixed to the side surface of the lifting frame 46; a high-pressure gas nozzle 49 is obliquely provided through the side surface of the extension plate 48; a mounting tube 50 is provided at one end of the high-pressure gas nozzle 49; the mounting tube 50 is connected to the ear tube 43 through a hose.

[0044] A specific application of this embodiment is:

[0045] When the top of the concrete test block 6 contains a lot of impurity particles, it needs to be scraped off. The specific operation is to rotate the screw 45 to drive the lifting frame 46 to slide along the inner wall of the sliding cavity 44, so as to adjust the height of the scraper 47, thereby improving the practicality of the device. During the loading process, the concrete test block 6 slides along the inner wall of the corresponding U-shaped seat 3. During the movement, the scraper 47 scrapes the top of the concrete test block 6 to scrape off the small particles of impurities on the top of the concrete test block 6. After scraping, the concrete test block 6 is turned over so that the top surface in the initial state is perpendicular to the ground. The bottom surface of the concrete test block 6 in the initial state is aligned with the frame opening of the detection frame 9 in the horizontal state, and is transported into the detection frame 9 in this state. When the detection frame 9 is rotated to be vertical to the ground, the top surface of the concrete test block 6 that has completed the impurity scraping in the initial state is aligned with the pressure plate 23; in the process of the scraper 47 scraping the impurity particles on the top of the concrete test block 6, the control valve on the ear tube 43 is controlled to be opened (the control valve on the branch pipe 39 is closed), and the compressed air passes through the ear tube 43, the corresponding hose and the installation pipe 50 in turn into the high-pressure air nozzle 49 for spraying, so as to blow away the scraped impurity particles.
