Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a safe and stable testing device for water conservancy projects. Background Technology
[0002] In water conservancy engineering construction, foundation strength testing is crucial. One commonly used testing method is to tap the foundation and judge its strength based on the feedback. However, existing testing methods have many safety hazards. During the tapping process, gravel, debris, and other small objects may fly from the foundation surface, which can easily injure the testing personnel. Moreover, after the test is completed, the testing personnel need to approach the test area for observation, which may lead to safety accidents due to unstable factors in the surrounding area, such as loose soil. At the same time, the traditional testing process lacks effective automatic protection and convenient observation mechanisms, affecting the efficiency and accuracy of the test. Utility Model Content
[0003] In view of the problems existing in the above-mentioned safe and stable testing devices for water conservancy projects, this utility model is proposed.
[0004] Therefore, the purpose of this utility model is to provide a safe and stable testing device for water conservancy projects, which solves the problems mentioned in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A safe and stable testing device for water conservancy projects includes a U-shaped frame and a striking block. The striking block is located below the U-shaped frame. A hydraulic cylinder is fixedly mounted on the lower surface of the middle end of the U-shaped frame. An electromagnet is fixedly mounted at the end of the piston rod of the hydraulic cylinder. The electromagnet is magnetically connected to the striking block. Through holes are opened on both sides of the lower side wall of the U-shaped frame. A sliding rod is slidably mounted inside the through hole. An arc-shaped baffle is fixedly mounted on one end of the inner side of the sliding rod. Vertical rods are fixedly mounted on the lower surface of the U-shaped frame on both sides of the hydraulic cylinder. A horizontal rod is movably sleeved on the wall of the vertical rod. A connecting mechanism fixedly connected to the striking block is provided at one end of the horizontal rod. A pulling mechanism that drives the arc-shaped baffle to move is provided at the other end of the horizontal rod.
[0007] Preferably, the connecting mechanism includes a connecting plate and a fixing block. The connecting plate is fixedly disposed at one end of the crossbar near the striking block, and the fixing block is fixedly disposed on the upper surface of the striking block and located on one side of the connecting plate. A threaded rod is threadedly sleeved inside the fixing block, and the other end of the threaded rod is threadedly connected to the connecting plate.
[0008] Preferably, the pulling mechanism includes a pull rope, a first guide wheel, and a second guide wheel. A first support plate is fixedly installed on the outer wall of the U-shaped frame and located behind the slide rod. The first guide wheel is rotatably mounted on the front side of the U-shaped frame via a first axle pin. A second support plate is fixedly installed on the inner wall of the U-shaped frame and located between the crossbar and the slide rod. The second guide wheel is rotatably mounted on the front side of the second support plate via a second axle pin. The pull rope is fixedly installed at one end of the outer side of the slide rod, and the other end of the pull rope is fixedly connected to one end of the outer side of the crossbar. The middle end of the pull rope abuts against the side of the first guide wheel away from the U-shaped frame and the lower side of the second guide wheel.
[0009] Preferably, the longitudinal section of both the slide rod and the through hole is rectangular.
[0010] Preferably, a spring is movably sleeved on the wall of the slide rod, and the two ends of the spring are fixedly connected to the inner wall of the U-shaped frame and the outer wall of the arc-shaped baffle, respectively.
[0011] Preferably, an anti-detachment block is fixedly provided at the lower end of the vertical rod.
[0012] Preferably, a knob is fixedly sleeved at one end of the threaded rod.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] 1. This utility model, through the setting of a hydraulic cylinder, an electromagnet and a striking block, can drive the electromagnet to move up and down through the hydraulic cylinder, that is, it can magnetically attract the striking block to a higher position, and then disconnect the power supply to the electromagnet, allowing the striking block to fall freely, so that the striking block can tap the foundation for testing, which is convenient to operate.
[0015] 2. This utility model, through the configuration of a crossbar, connecting mechanism, pulling mechanism, sliding rod, and arc-shaped baffle, allows the crossbar to move downwards along with the striking block when the striking block strikes, thus loosening the pull rope. Under the action of the spring, the sliding rod drives the arc-shaped baffle to move inwards and reset, shielding the detection area to prevent the splashing of gravel and debris, ensuring the safety of the testing personnel. After the test is completed, the striking block moves upwards, and the crossbar also moves upwards. Driven by the pulling mechanism, the sliding rod drives the arc-shaped baffle to move away from the striking block, facilitating the observation of the testing situation by the testing personnel. This achieves the functions of automatic shielding and opening of the shield, improving the safety and convenience of the test. Attached Figure Description

Detailed Implementation
[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model discloses a safe and stable testing device for water conservancy projects.
[0024] Reference Figure 1-3 A safe and stable testing device for water conservancy projects includes a U-shaped frame 1 and a striking block 4. The striking block 4 is located below the U-shaped frame 1. A hydraulic cylinder 2 is fixedly installed on the lower surface of the middle end of the U-shaped frame 1. An electromagnet 3 is fixedly installed at the end of the piston rod of the hydraulic cylinder 2. The electromagnet 3 is magnetically connected to the striking block 4. Through holes are opened on both sides of the lower side wall of the U-shaped frame 1. A sliding rod 7 is slidably installed inside the through hole. An arc-shaped baffle 8 is fixedly installed at one end of the inner side of the sliding rod 7. Vertical rods 5 are fixedly installed on the lower surface of the U-shaped frame 1 on both sides of the hydraulic cylinder 2. A horizontal rod 6 is movably sleeved on the rod wall of the vertical rod 5. An anti-detachment block is fixedly installed at the lower end of the vertical rod 5 to prevent the horizontal rod 6 from slipping off the rod wall of the vertical rod 5 as much as possible.
[0025] Reference Figure 1-3One end of the crossbar 6 is provided with a connecting mechanism that is fixedly connected to the striking block 4. The connecting mechanism includes a connecting plate 17 and a fixing block 18. The connecting plate 17 is fixedly set at one end of the crossbar 6 near the striking block 4. The fixing block 18 is fixedly set on the upper surface of the striking block 4 and located on one side of the connecting plate 17. A threaded rod 19 is threadedly sleeved inside the fixing block 18. The other end of the threaded rod 19 is threadedly connected to the connecting plate 17. A knob is fixedly sleeved at one end of the threaded rod 19 to facilitate rotation of the threaded rod 19.
[0026] Reference Figure 1-3 The other end of the crossbar 6 is provided with a pulling mechanism that drives the arc-shaped baffle 8 to move. The pulling mechanism includes a pull rope 15, a first guide wheel 12 and a second guide wheel 14. A first support plate 10 is fixedly installed on the outer wall of the U-shaped frame and behind the slide bar 7. The first guide wheel 12 is rotatably installed on the front side of the U-shaped frame through a first shaft pin 11. A second support plate 16 is fixedly installed on the inner wall of the U-shaped frame 1 and between the crossbar 6 and the slide bar 7. The second guide wheel 14 is rotatably installed on the front side of the second support plate 16 through a second shaft pin 13. The pull rope 15 is fixedly installed on one side of the slide bar 7. The other end of the pull rope 15 is fixedly connected to one side of the crossbar 6. The middle end of the pull rope 15 abuts against the side of the first guide wheel 12 away from the U-shaped frame 1 and the lower side of the second guide wheel 14.
[0027] Reference Figure 1-3 The longitudinal section of both the slide rod 7 and the through hole is rectangular, which makes the slide rod 7 unable to rotate, that is, it can slide stably. The wall of the slide rod 7 is movably sleeved with a spring 9. The two ends of the spring 9 are fixedly connected to the inner wall of the U-shaped frame 1 and the outer wall of the arc-shaped baffle 8, respectively. The slide rod 7 drives the arc-shaped baffle 8 to reset.
[0028] In this invention, during use, the U-shaped frame 1 is first placed above the foundation to be inspected and its position adjusted. By rotating the knob at one end of the threaded rod 19, the threaded rod 19 is rotated, tightly connecting the connecting plate 17 and the fixing block 18, thereby firmly connecting the crossbar 6 and the striking block 4. Next, the hydraulic cylinder 2 is activated, and the piston rod of the hydraulic cylinder 2 extends, driving the electromagnet 3 to rise. Since the electromagnet 3 is magnetically connected to the striking block 4, the striking block 4 also rises. After reaching the predetermined height, the power to the electromagnet 3 is turned off, and the striking block 4 loses its magnetic attraction and falls freely under the action of gravity, striking the foundation. During the descent of the striking block 4, the crossbar 6 descends along with the striking block 4. The descent of the crossbar 6 causes the pull rope 15 to loosen. At this time, the sliding rod 7 slides inward under the elastic force of the spring 9, driving the arc-shaped... The baffle 8 moves towards the center, blocking the inspection area and effectively preventing the flying of gravel and debris generated during the foundation impact, thus protecting the safety of the inspection personnel. After the impact is completed, the hydraulic cylinder 2 is activated again, the piston rod retracts, driving the electromagnet 3 and the impact block 4 to rise. The crossbar 6 also rises with the impact block 4. During the rise of the crossbar 6, the pull rope 15 is pulled. Guided by the first guide wheel 12 and the second guide wheel 14, the pull rope 15 drives the sliding rod 7 to slide outward, causing the arc-shaped baffle 8 to move away from the impact block 4, thereby opening the blocked area and facilitating the inspection personnel to observe the foundation inspection status. If it is necessary to replace the impact block 4 with a different specification, simply rotate the knob in the opposite direction to unscrew the threaded rod 19 from the connecting plate 17 and the fixing block 18, thus separating the crossbar 6 from the impact block 4 for replacement.
[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
