Description

Technical Field

[0002] In water conservancy projects, foundation testing is a key link to ensure the safety and stability of the project, and involves a variety of physical, mechanical and geological property analyses. The testing content usually includes physical properties, mechanical properties, permeability, geological structure, groundwater level and pollutants.

[0003] The dynamic penetration tester (DPT) is an important instrument in foundation testing. When in use, the probe rod is erected and the probe is brought into contact with the surface of the foundation to be tested. The core hammer is manually lifted to a certain height and allowed to fall freely. The core hammer is used to strike the hammer seat and the probe rod is inserted into the foundation. The number of hammer strikes required for the probe rod to penetrate a certain depth into the foundation is counted, and the bearing capacity of the foundation is calculated using a formula.

[0085] The motor 71 drives the rotating disk 72 to rotate, and the rotating disk 72 drives the eccentric rod 73 to rotate. When the eccentric rod 73 rotates to abut against the bottom of the connecting plate 74, it drives the connecting plate 74 to move upward, and the connecting plate 74 drives the impact hammer 5 to move upward. When the eccentric rod 73 rotates to disengage from the connecting plate 74, the impact hammer 5 moves downward under the action of gravity, hitting the right-angle plate 6 and the limit block 3, so that the detection head 2 is inserted into the ground.

Under the action of pressure, the sliding rod 1 838 drives the positioning arc plate 82 to move to abut against the fixed rod 10, and fix the right angle plate 6. When the eccentric rod 73 rotates to abut against the connecting plate 74, although the eccentric rod 73 and the connecting plate 74 collide when they contact, due to the positioning of the positioning arc plate 82, the right angle plate 6 will not move downward under the impact force.

[0103] Magnet 2 8314 is connected to the fixed tube 832 and has opposite magnetic properties to magnet 1 8313 .

[0104] The rotating disk 72 drives the missing gear 8311 to rotate. When the missing gear 8311 rotates to engage with the tooth plate 8312, it drives the tooth plate 8312 to move. The tooth plate 8312 drives the connecting rod 8310 to move toward the side away from the right-angle plate 6. At the same time, the tooth plate 8312 drives the magnet 1 8313 to move. When the magnet 1 8313 moves to abut against the magnet 2 8314, the missing gear 8311 is disengaged from the tooth plate 8312, and the magnet 1 8313 and the magnet 2 8314 are adsorbed together to position the tooth plate 8312.

[0105] As an embodiment of the present invention, please refer to Figure 1 , Figures 3 to 7 , the connectivity component 836 includes:

[0106] The bottom end of the folded tube 8361 is connected to the interior of the fixed tube 832 away from the right angle plate 6;

[0107] The arc frame 8362 is connected to the top of the folded tube 8361. There are two groups of arc frames 8362, which are respectively located on both sides of the right angle plate 6. The two groups of arc frames 8362 are connected through a pipeline.

[0108] The top end of the connecting tube 8363 is connected to the interior of the arc frame 8362, and the bottom end is connected to the interior of the connecting tube 837.

[0109] Piston 834 moves toward the side away from the right-angle plate 6, pressing the air inside the fixed cylinder 832 into the folded tube 8361. The air enters the several groups of connecting tubes 8363 through the arc frame 8362, and then enters the connecting cylinder 837, causing the sliding rod 838 to move toward the side close to the fixed rod 10, driving the positioning arc plate 82 to move until it abuts against the fixed rod 10, thereby positioning the right-angle plate 6.

[0110] As an embodiment of the present invention, please refer to Figure 1 , Figures 3 to 8 , the decompression component 84 includes:

[0111] The second piston 841 is located inside the fixed cylinder 832 on one side close to the right angle plate 6 and is slidably engaged with the inner wall thereof. The second piston 841 is connected to the connecting rod 8310;

[0114] The smooth component 844 has one end connected to the positioning arc plate 82 and the other end abutting against the fixing rod 10 to ensure smooth movement of the right-angle plate 6.

[0115] When the positioning arc plate 82 abuts against the fixed rod 10, the elastic frame 843 is filled with gas and is in an expanded state, and the smooth component 844 is inside the positioning arc plate 82. When the eccentric rod 73 drives the connecting plate 74 to move upward and abut against the elastic frame 843, the connecting plate 74 squeezes the elastic frame 843, and presses the internal gas of the elastic frame 843 into the fixed cylinder 832 through the fixed tube 842, so that the piston 2 841 moves toward the side close to the right angle plate 6, and cooperates with the elastic member 1 835. The piston 2 841 drives the connecting rod 8310 to move, and the connecting rod 8310 drives the piston 1 834 to move, and the internal gas of the connecting cylinder 1 837 is extracted. Cooperating with the elastic member 2 839, the sliding rod 1 838 drives the positioning arc plate 82 to move toward the side away from the fixed rod 10, thereby releasing the limit on the right angle plate 6. At the same time, the smooth component 844 extends out of the positioning arc plate 82, so that the right angle plate 6 moves stably in the longitudinal direction.

[0116] As an embodiment of the present invention, please refer to Figure 5 , Figure 7 and Figure 8 , the smooth component 844 includes:

[0122] The elastic member 3 8446 has one end connected to the positioning arc plate 82 and the other end connected to the arc seat 8444 .

[0123] When the positioning arc plate 82 abuts against the fixed rod 10, the elastic member 3 8446 is in a compressed state, and the ball 8445 abuts against the fixed rod 10. When the sliding rod 1 838 moves to the side away from the fixed rod 10, the positioning arc plate 82 is driven to move, so that the positioning arc plate 82 is away from the fixed rod 10. At the same time, under the reaction force of the elastic member 3 8446, the ball 8445 continues to abut against the fixed rod 10, and the ball 8445 ensures that the right angle plate 6 moves downward stably and smoothly. The elastic member 3 8446 can be a spring, a spring sheet, etc.

[0125] The sliding plate 12 is connected to the fixing rod 10 and is slidably engaged with the ground-inserting rod 1 .

[0126] The sliding plate 12 limits the ground-inserting rod 1 to ensure that the ground-inserting rod 1 moves linearly and stably, so that the detection head 2 is vertically inserted into the ground.

[0127] The working principle of the present invention is: the ground insertion rod 1, the detection head 2, the limit block 3 and the limit rod 4 are spliced ​​together, and the limit rod 4 is slidably engaged with the right-angle plate 6, and the impact hammer 5 is slidably engaged with the limit rod 4. In the initial state of impact, the impact hammer 5 is located on the right-angle plate 6, and the motor 71 drives the rotating disk 72 to rotate, and the rotating disk 72 drives the eccentric rod 73 to rotate. At the same time, the rotating disk 72 drives the missing gear 8311 to rotate. When the missing gear 8311 rotates to engage with the tooth plate 8312, it drives the tooth plate 8312 to move, and the tooth plate 8312 drives the connecting rod 8310 to move toward the side away from the right-angle plate 6, and the tooth plate 8312 drives the magnet 8313 to move. When the eccentric rod 73 moves to the point where it is about to When it abuts against the connecting plate 74, magnet 1 8313 moves to abut against magnet 2 8314, the missing gear 8311 is disengaged from the tooth plate 8312, and magnet 1 8313 and magnet 2 8314 are adsorbed together to position the tooth plate 8312. During this process, the tooth plate 8312 drives the connecting rod 8310 to move toward the side away from the right-angle plate 6, and the connecting rod 8310 drives the piston 1 834 to move, and the air on the side of the fixed cylinder 832 away from the right-angle plate 6 is pressed into the inside of the connecting cylinder 1 837. Under the action of pressure, the sliding rod 1 838 drives the positioning arc plate 82 to move to abut against the fixed rod 10, thereby fixing the right-angle plate 6. When the eccentric rod 73 rotates to abut against the connecting plate 74 When the eccentric rod 73 is connected, a collision occurs when the eccentric rod 73 contacts the connecting plate 74, but due to the positioning of the positioning arc plate 82, the right-angle plate 6 will not move downward under the impact force. At the same time, the piston 841 moves to press the internal air on the side of the fixed cylinder 832 close to the right-angle plate 6 into the elastic frame 843. The elastic frame 843 is filled with gas and is in an expanded state. The eccentric rod 73 continues to move to drive the connecting plate 74 to move upward, and drives the impact hammer 5 to move upward. When the eccentric rod 73 drives the connecting plate 74 to move upward and abut against the elastic frame 843, the connecting plate 74 squeezes the elastic frame 843, and presses the internal gas of the elastic frame 843 into the fixed cylinder 832 through the fixed tube 842, so that the piston 841 841 moves toward the side close to the right-angle plate 6, cooperates with the elastic part 1 835, and the piston 2 841 drives the connecting rod 8310 to move, and the connecting rod 8310 drives the piston 1 834 to move, and the internal gas of the connecting tube 1 837 is extracted, and cooperates with the elastic part 2 839, so that the sliding rod 1 838 drives the positioning arc plate 82 to move toward the side away from the fixed rod 10, and the limit on the right-angle plate 6 is released. When the eccentric rod 73 moves to separate from the impact hammer 5, the impact hammer 5 moves downward under the action of gravity and collides with the right-angle plate 6. Under the action of the impact force, the right-angle plate 6, the ground insertion rod 1, the detection head 2, the limit block 3 and the limit rod 4 move downward synchronously, and the detection head 2 is inserted into the ground for detection.
