[0021] like Figure 1-10As shown, this invention provides an automatic heavy-duty dynamic penetration test device for measuring foundation bearing capacity, including a base frame 1. A motion mechanism is provided at the lower part of the base frame 1 to drive the entire device. Fixing mechanisms are fixedly connected to the four outer corners of the base frame 1 to secure it during measurement and prevent shaking or movement from affecting the measurement. A lifting mechanism is provided on the base frame 1 to adjust the height of a lifting frame 17 for easy measurement. A moving mechanism is provided on the lifting frame 17 to move a moving frame 20. A dynamic penetration test mechanism is connected to the moving frame 20 for dynamic penetration during measurement. A braking mechanism is connected to the moving frame 20 to brake the dynamic penetration test mechanism. A counterweight adjustment mechanism is connected to the dynamic penetration test mechanism to adjust the counterweight during dynamic penetration.

[0022] Advantageously, the power probing mechanism includes a groove on the movable frame 20, through which a retrieval shaft 37 is rotatably connected. A retrieval driven gear 36 is fixedly connected to one end of the retrieval shaft 37. The retrieval driven gear 36 meshes with a retrieval driving gear 38. The retrieval driving gear 38 is fixedly mounted at the end of a retrieval driving gear shaft 57. The retrieval driving gear shaft 57 is rotatably mounted on the movable frame 20. The retrieval driving gear shaft 57 is poweredly connected to a lifting motor fixedly mounted inside the movable frame 20. The outer surface of the retrieval shaft 37 within the groove is fixedly mounted... A rotating drum 22 is provided, on which a rope 6 is wound and connected. The end of the rope 6 is fixedly connected to a slider 85. The slider 85 is slidably connected to an upper slide rail 86 and a lower slide rail 48. The upper slide rail 86 is fixedly mounted on the movable frame 20, and the lower slide rail 48 is fixedly mounted on a lower slide rail connecting frame 47. The lower slide rail connecting frame 47 is slidably connected to the lower part of the base frame 1. The lower slide rail 48 is inserted into the upper slide rail 86 and slidably connected to it. A counterweight box 21 is fixedly connected between the sliders 85. A tube 46 is fixedly connected to the lower part of the counterweight box 21. A pin 73 is inserted into the counterweight box 21. A baffle 74 is fixedly connected to the outer surface of the pin 73. A grooved frame 43 is symmetrically fixedly connected to the lower surface of the counterweight box 21. An electric lead screw 45 is rotatably connected to the grooved frame 43. A clamping nut block 44 is threadedly connected to the outer surface of the electric lead screw 45 and slidably connected to the grooved frame 43. A clamping electric push rod 39 is fixedly installed on the bottom wall of the clamping nut block 44. A clamping plate 40 is fixedly connected to the lower end of the clamping electric push rod 39. The clamping plate 40 clamps the surface of the pin 73 under the baffle 74. The lower end of the baffle 74 is fixedly connected to... A gravity ball 79 is attached. After being disassembled, the gravity ball 79 is placed on a placement tray 29. The placement tray 29 is fixedly installed on the base frame 1. A measuring component frame 33 is fixedly installed on the base frame 1. A measuring component hole 34 is provided through the measuring component frame 33. An electric clamping assembly is installed in the measuring component hole 34. The electric clamping assembly is used to clamp the corresponding measuring component 32. Different measuring component holes 34 clamp measuring components 32 of different shapes. A post 73 is fixedly installed on the upper part of each measuring component 32. A baffle 74 is fixedly installed on the outer surface of the post 73. During operation, after the counterweight box 21 reaches a certain height, the braking mechanism releases the brake, allowing the counterweight box 21 to move freely downwards. This causes the insertion cylinder 46 to move downwards, which in turn causes the insertion post 73 to move downwards, resulting in the gravity ball 79 striking the foundation. The depth of the indentation on the foundation is used to measure and calculate the bearing capacity of the foundation. Upon resetting, the lifting motor is activated, causing the recovery drive gear shaft 57 to rotate, which in turn causes the recovery drive gear 38 to rotate. The recovery drive gear 38 meshes with the recovery driven gear 36, causing the recovery rotating shaft 37 to rotate, which in turn causes the rotating drum 22 to rotate. This causes the rope 6 to move and be wound up on the rotating drum 22, which in turn causes the slider 85 to move upwards, resulting in the counterweight box 21 moving upwards to reset. When the corresponding measuring component 32 needs to be replaced, the counterweight box... The counterweight box 21 moves to the upper position of the placement plate 29, energizes the electric lead screw 45 to rotate, thereby driving the clamping nut block 44 to move, thereby driving the clamping electric push rod 39 to move, thereby driving the clamping plate 40 to move, releasing the clamping of the insertion post 73, thereby placing the gravity ball 79 on the placement plate 29. After the counterweight box 21 moves to the upper side of the corresponding measuring component 32, the electric lead screw 45 rotates, thereby driving the clamping nut block 44 to move and reset, thereby driving the clamping electric push rod 39 to move. The clamping electric push rod 39 is energized, causing the clamping electric push rod 39 to move downward, driving the clamping plate 40 to move downward, and following the movement of the clamping nut block 44, thereby clamping the insertion post 73. After clamping, the clamping electric push rod 39 resets upward, thereby inserting the insertion post 73 into the insertion cylinder 46, thereby realizing replacement.

[0023] Advantageously, the counterweight adjustment mechanism includes a fixed plate 23 fixedly installed between the movable frames 20. A hollow electric push rod 24 for weight increase is fixedly installed on the fixed plate 23.

The upper end of the hollow electric push rod 24 is fixedly connected to one end of a water supply pipe 13. The other end of the water supply pipe 13 is fixedly connected to a weight increase water pump 12. The weight increase water pump 12 is fixedly installed on the counterweight liquid tank 9, communicating with the inside of the counterweight liquid tank 9. The counterweight liquid tank 9 is fixedly installed on the base frame 1. Above, the inlet of the weight-increasing water pump 12 is connected to the extraction pipe, which extends to the vicinity of the bottom wall inside the counterweight liquid tank 9. A weight-reducing negative pressure extraction pump 10 is fixedly installed on the counterweight liquid tank 9. One end of a return pipe 11 is fixedly connected to the upper side of the weight-reducing negative pressure extraction pump 10. The other end of the return pipe 11 is connected to a weight-reducing hollow electric push rod 26. The weight-reducing hollow electric push rod 26 is fixedly installed on the fixed plate 23. The weight-reducing hollow electric push rod 26 is inserted into the weight-reducing connecting valve 27 and communicates with the weight-reducing connecting valve 27. An extraction pipe 72 is connected to the lower side of the weight-reducing connecting valve 27, and the extraction pipe 72 extends to the vicinity of the bottom wall inside the counterweight tank 21. During operation, adding counterweight activates the weight-adding water pump 12, drawing liquid from it and supplying it through the water pipe 13 to the weight-adding hollow electric actuator 24. Energizing the weight-adding hollow electric actuator 24 causes it to move downwards and insert into the weight-adding connecting valve 25, allowing liquid to pass through the valve and enter the counterweight box 21, thus increasing the counterweight. To decrease the counterweight, energizing the weight-reducing hollow electric actuator 26... The weight-reducing hollow electric push rod 26 moves downward and inserts into the weight-reducing connecting valve 27, activating the weight-reducing negative pressure extraction pump 10. This allows the liquid in the counterweight box 21 to enter the weight-reducing connecting valve 27 through the extraction pipe 72, then through the weight-reducing hollow electric push rod 26 into the return pipe 11 and into the weight-reducing negative pressure extraction pump 10, and finally into the counterweight liquid tank 9. This enables the reuse of the liquid and reduces the counterweight. By adjusting the counterweight, various measurements can be performed, increasing measurement efficiency.

The brake drive gear 64 meshes with the brake ring rack 60, thereby driving the brake ring rack 60 to rotate. The brake ring rack 60 meshes with the brake driven gear 63, thereby driving the brake lead screw 61 to rotate, thereby pushing the brake threaded cylinder 87 to move, thereby pushing the brake insert 62 to move and insert into the brake disc 59, thereby achieving braking of the recovery shaft 37.
