Abstract
Description
Technical Field
[0001] This invention relates to the field of foundation strength testing technology, specifically to a foundation strength testing device for buildings. Background Technology
[0002] Foundation strength refers to the ability of the foundation to resist damage under the load of a building. If the foundation soil undergoes compressive deformation under the load of a building, causing a large settlement, it can lead to the overall tilting of the building structure and pose a safety hazard. Referring to Chinese patent publication number "CN217758665U" entitled "A Foundation Strength Testing Device for Buildings," this patent points out that most current strength testing devices involve workers manually raising a collision block and then letting it fall naturally to impact the ground. However, the collision block is directly engaged with the connecting cylinder, resulting in significant friction during the fall, which reduces the impact force on the ground and thus lowers the accuracy of the test. Furthermore, this device still suffers from the problem of cumbersome impact force adjustment, affecting the ease of operation. To address these issues, we propose a foundation strength testing device for buildings. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention provides a building foundation strength testing device, which solves the problems mentioned in the background section.
[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a building foundation strength testing device, comprising a body, a protective frame fixedly installed on the top of the body, and a drive device fixedly installed inside the protective frame, a traction rope wound inside the drive device, the end of the traction rope passing through the inside of the body and fixedly installed with a testing shaft, and a testing pressure plate fixedly installed at the end of the testing shaft, the testing pressure plate being used to perform impact testing on the building foundation;
[0005] An adjusting ring frame is fixedly installed on the top inner side of the machine body. The installation position of the adjusting ring frame is coaxial with the detection shaft. The adjusting ring frame contains multiple counterweight ring frames, which are used to assemble the corresponding number of counterweight ring frames to the outside of the detection shaft according to different punching pressure. A locking component is provided between the adjusting ring frame and the counterweight ring frame, which is used to lock different numbers of counterweight ring frames to the adjusting ring frame.
[0006] The locking assembly includes a limit adjustment frame, a sliding bushing is slidably installed inside the limit adjustment frame, and a plug-in slide rod is slidably installed inside the sliding bushing. Multiple plug-in through holes adapted to the plug-in slide rod are symmetrically opened inside the adjustment ring frame and the counterweight ring frame, respectively, for locking the corresponding counterweight ring frame and adjustment ring frame by inserting the plug-in slide rod into the corresponding plug-in through hole.
[0007] Preferably, sliders are fixedly installed on both sides of the sliding bushing, and limit slots are symmetrically opened on both sides of the inner side of the limit adjustment frame, with the sliders slidably connected inside the corresponding limit slots.
[0008] Preferably, a return spring is sleeved at the end of the plug-in slide rod, and the return spring is used to drive the plug-in slide rod to return to its original position.
[0009] Preferably, a connecting end is fixedly installed at the end of the detection shaft, and the end of the traction rope is fixedly connected to the connecting end.
[0010] Preferably, a limiting shaft is rotatably connected to the top of the machine body, and the traction rope passes around the limiting shaft.
[0011] Preferably, a movable frame is fixedly installed at the bottom of the machine body, and multiple movable wheels are rotatably connected to the bottom of the movable frame.
[0012] Preferably, both sides of the movable frame are slidably connected to support frames, and support pads are fixedly installed at the ends of the support frames.
[0013] Preferably, a rectangular protective frame is slidably connected inside the machine body. The rectangular protective frame is used to move downward as the detection pressure plate moves downward to protect the impact position of the detection pressure plate.
[0014] Preferably, auxiliary ropes are fixedly installed on both sides of the top of the rectangular protective frame, and the ends of the two auxiliary ropes away from the auxiliary rope are fixedly connected to the traction rope.
[0015] Preferably, a limiting frame is fixedly installed on both sides of the inside of the machine body, and a limiting wheel is rotatably connected inside the limiting frame. The auxiliary rope passes around the corresponding limiting wheel. An arc-shaped storage rack is fixedly installed on both sides of the inside of the machine body, and the auxiliary rope passes through the corresponding arc-shaped storage rack and is slidably connected to it.
[0016] This invention provides a device for testing the foundation strength of buildings. Compared with the prior art, it has the following advantages:
[0017] (1) The building foundation strength testing device, by adjusting the ring frame and multiple counterweight ring frames, when it is necessary to adjust the impact force, simply move the testing shaft rod upward by the traction rope and insert it into the multiple counterweight ring frames. Then, by adjusting the insertion position of the insertion slide rod, different numbers of counterweight ring frames can be locked. When the testing pressure plate moves down to perform impact testing on the building foundation, the impact adjustment can be completed by the cooperation of different counterweight ring frames. Compared with the traditional method, the ease of operation of the equipment is further improved.
[0018] (2) The building foundation strength testing device, through the setting of the rectangular protective frame, when the drive device is unlocked, the rectangular protective frame can move down with the help of the auxiliary rope to contact the ground. When the testing pressure plate and the counterweight ring frame move down to contact the ground for impact operation, the rectangular protective frame can protect the impact position, further improving the safety of operation.

[0029] Please see Figures 1-8 The present invention provides two technical solutions, specifically including the following embodiments:
[0030] Example 1:
[0031] In this embodiment of the invention, a building foundation strength testing device includes a body 1, a protective frame 5 fixedly installed on the top of the body 1, a drive device 6 fixedly installed inside the protective frame 5, a traction rope 7 wound inside the drive device 6, the end of the traction rope 7 passing through the inside of the body 1 and fixedly installed with a testing shaft 8, and a testing pressure plate 801 fixedly installed at the end of the testing shaft 8. The testing pressure plate 801 is used to perform impact testing on the building foundation.
[0032] In this embodiment of the invention, specifically, the driving device 6 is an existing winding device, which consists of multiple mechanisms such as a winding roller and a brake, and is used to realize the winding operation of the traction rope 7, which will not be described in detail here;
[0033] In this embodiment of the invention, specifically, when conducting impact testing on the building foundation, the drive device 6 is first operated to wind the traction rope 7, causing the detection pressure plate 801 to rise to a preset height. Then, the brake in the drive device 6 is released, causing the detection pressure plate 801 to fall and impact the building foundation.
[0034] In this embodiment of the invention, specifically, an adjusting ring frame 10 is fixedly installed on the top inner side of the body 1. The installation position of the adjusting ring frame 10 is coaxial with the detection shaft 8. The adjusting ring frame 10 contains multiple counterweight ring frames 9, which are used to assemble the corresponding number of counterweight ring frames 9 to the outside of the detection shaft 8 according to different punching pressure. A locking component is provided between the adjusting ring frame 10 and the counterweight ring frames 9, which is used to lock different numbers of counterweight ring frames 9 to the adjusting ring frame 10.

[0038] In this embodiment of the invention, specifically, when it is necessary to select the counterweight ring frame 9 according to different impact forces, the detection shaft 8 is first wound by the traction rope 7, so that it can move upward with the traction rope 7 until the detection shaft 8 enters the interior of the adjustment ring frame 10. At this time, the detection shaft 8 can pass through multiple counterweight ring frames 9 until the detection pressure plate 801 and the bottom of the adjustment ring frame 10 are in contact with each other. Then, by pulling the insertion slide rod 14 outward, the locking of the counterweight ring frame 9 and the adjustment ring frame 10 is released.

[0041] In this embodiment of the invention, specifically, by adjusting the arrangement of the ring frame 10 and multiple counterweight ring frames 9, when it is necessary to adjust the impact force, it is only necessary to use the traction rope 7 to drive the detection shaft 8 to move upward and insert it into the multiple counterweight ring frames 9. Then, by adjusting the insertion position of the insertion slide rod 14, different numbers of counterweight ring frames 9 can be locked. This allows the impact adjustment to be completed by the cooperation of different counterweight ring frames 9 when the detection pressure plate 801 moves downward to perform impact testing on the foundation of the house. Compared with the traditional method, this further improves the ease of operation of the equipment.

At this time, the detection shaft 8 can pass through multiple counterweight ring frames 9 until the detection pressure plate 801 and the bottom of the adjustment ring frame 10 are in contact with each other. Then, by pulling the insertion slide rod 14 outward, the locking of the counterweight ring frame 9 and the adjustment ring frame 10 is released. Then, the insertion slide rod 14 drives the sliding bushing 12 to slide inside the limit adjustment frame 11 to adjust the height of the insertion slide rod 14.
