Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a foundation static load detection testing machine. Background Art

[0002] With the continuous development and progress of modern architecture, foundation testing has become an indispensable part of the construction field. Through the testing of foundations, we can understand the bearing capacity, stability and safety of buildings, and provide important reference for the design and construction of buildings.

[0003] Currently available foundation static load testing machines are not easy to move, which requires additional handling equipment or manpower, which is time-consuming and labor-intensive, reduces work efficiency, and cannot adjust the level of the device, and cannot eliminate the interference of incorrect tilt or inclination on the measurement results, affecting the reliability of the data. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art, that is, the inconvenience of movement, the reduced working efficiency, the inability to adjust the horizontality of the device, and the influence on the reliability of data, and proposes a foundation static load detection testing machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A foundation static load detection testing machine, comprising:

[0007] A fixed beam, wherein two fixed beams are symmetrically arranged, and three evenly distributed support beams are fixedly arranged on the tops of the two fixed beams;

[0008] An adjustment mechanism, which is arranged on the fixed beam and is used to adjust the height and levelness of the testing machine;

[0009] The moving assembly is arranged on the fixed beam and is used to facilitate the movement of the testing machine.

[0010] In a possible design, the adjustment mechanism includes two hydraulic cylinders that are symmetrically embedded at the bottom of two fixed beams, and the output ends of the four hydraulic cylinders are fixed with support pads, and the bottoms of the four support pads are provided with anti-slip strips.

[0011] In a possible design, the movable component includes two threaded rods that are symmetrically threadedly connected to the bottom of two fixed beams, the bottom of the four threaded rods are fixedly provided with adjustment blocks, and the bottom of the four adjustment blocks are rotatably provided with moving wheels, and the outside of the four threaded rods are threadedly connected with nuts.

[0012] In a possible design, a fixing seat is fixedly provided at the bottom of the support beam located in the middle, a jack is fixedly provided at the bottom of the fixing seat, and a pressure plate is fixedly provided at the output end of the jack.

[0013] In a possible design, a same bearing plate is fixedly provided on the top of the three support beams, and an anti-slip pad is fixedly provided on the top of the bearing plate.

[0014] In a possible design, the top of the carrying plate may be detached from a plurality of evenly distributed counterweight beams stacked thereon.

[0015] In the present application, when starting to use, the test machine is moved to the position where it needs to be used via the moving wheels. When the road surface is uneven or has a slope, the adjusting block on the threaded rod is rotated by a tool. While rotating, the adjusting block drives the threaded rod to rotate out from the bottom of the fixed beam, thereby lifting up the corresponding side of the fixed beam. Subsequently, the four adjusting blocks are adjusted in sequence according to the above operation to adjust the height of the moving wheel, and then the nut is rotated so that the nut moves upward on the threaded rod until it contacts the bottom of the fixed beam, so that the test machine can adapt to different ground conditions, which helps to ensure that the test machine can be moved in different environments and the installation is convenient. The device does not require additional handling equipment or manpower, which improves the flexibility of the device. When the device is moved to the foundation pile, the device is pushed again so that the hydraulic cylinder and the pressure plate are located at the foundation pile. Then, the four adjustment blocks are adjusted in sequence according to the above operation to adjust the height of the four moving wheels, thereby increasing the height of the device. Then, the nut is turned so that the nut moves upward on the threaded rod until it abuts against the bottom of the fixed beam, so that the hydraulic cylinder and the pressure plate are located directly above the foundation pile. The four hydraulic cylinders and jacks on the device are connected to the corresponding oil pumps respectively, and then the four hydraulic cylinders are pressurized by the oil pumps at the same time so that the hydraulic The output end of the hydraulic cylinder pushes the support pad to move in the direction of the ground and resist against the ground, so that the whole device is lifted until the moving wheel is off the ground, and then the nut is turned to move downward on the threaded rod, and then the adjusting block is turned to make the threaded rod and the moving wheel move upward until the position of the moving wheel is in the initial state, and then the oil pump is used to relieve the pressure of the four hydraulic cylinders at the same time so that the output end of the hydraulic cylinder drives the support pad to retract, thereby driving the whole device to descend until the pressure plate contacts the top of the foundation pile and stops the descent of the device. When the ground is uneven, the corresponding hydraulic cylinder can be controlled by the oil pump alone to adjust it. Applying pressure or releasing pressure can change the height of the corresponding position, thereby completing the adjustment of the horizontality of the device, eliminating the interference of incorrect tilt or inclination on the measurement results, and ensuring reliable data. Then, the corresponding number of configuration beams are stacked on the bearing plate. After placement, a displacement sensor is installed between the pressure plate and the ground, and the two ends of the displacement sensor are respectively against the pressure plate and the ground. Axial pressure is applied to the jack step by step through the oil pump. After the detection is completed, the displacement sensor is used to check the settlement of the foundation pile over time, and then the ultimate bearing capacity and bearing capacity characteristic value of the foundation pile are determined based on the recorded load and settlement data.

[0016] The utility model has the following beneficial effects:

[0017] The utility model provides an adjusting mechanism, wherein the four hydraulic cylinders on the device are connected to the corresponding oil pumps, and then the four hydraulic cylinders are pressurized by the oil pumps at the same time so that the output ends of the hydraulic cylinders push the support pads to move in the direction of the ground and contact the ground, thereby raising the device as a whole, and then the four hydraulic cylinders are depressurized by the oil pumps at the same time so that the output ends of the hydraulic cylinders drive the support pads to retract, thereby driving the device as a whole to descend until the pressure plate contacts the top of the foundation piles, and the device stops descending. When the ground is uneven, the corresponding hydraulic cylinders can be controlled separately by the oil pumps to apply pressure or release pressure to change the height of the corresponding positions, thereby completing the adjustment of the horizontality of the device, eliminating the interference of incorrect tilt or inclination on the measurement results, and ensuring reliable data.

[0018] The utility model uses the setting of the mobile assembly to move the test machine to the position where it needs to be used through the mobile wheels. When the road surface is uneven or has a slope, the adjusting block on the threaded rod is rotated by a tool, and the adjusting block drives the threaded rod to rotate out from the bottom of the fixed beam while rotating, so as to lift up the corresponding side of the fixed beam. Then, the four adjusting blocks are adjusted in sequence according to the above operation, so as to adjust the height of the mobile wheels, so that the test machine can adapt to different ground conditions, which helps to ensure that the test machine can be moved in different environments, so that the device does not need additional handling equipment or manpower, and the flexibility of the device is improved;

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1

[0027] Reference Figure 1-4 , a testing machine, comprising:

[0028] A fixed beam 1, wherein two fixed beams 1 are symmetrically arranged, and three evenly distributed support beams 2 are fixedly arranged on the top of the two fixed beams 1;

[0029] An adjustment mechanism, which is arranged on the fixed beam 1 and is used to adjust the height and levelness of the testing machine;

[0030] The moving component is arranged on the fixed beam 1 and is used to facilitate the movement of the testing machine.

[0031] The above technical solution can achieve the adjustment of the horizontality of the device through the setting of the adjustment mechanism, eliminate the interference of incorrect tilt or inclination on the measurement results, and ensure reliable data. The setting of the mobile component can facilitate the movement of the device. At the same time, the height of the mobile wheel 12 can be adjusted, so that the test machine can adapt to different ground conditions, which helps to ensure that the test machine can be moved in different environments, so that the device does not require additional handling equipment or manpower, thereby improving the flexibility of the device.

[0032] Reference Figure 1-2 The adjustment mechanism includes two hydraulic cylinders 5 which are symmetrically embedded at the bottom of the two fixed beams 1. The output ends of the four hydraulic cylinders 5 are fixedly provided with support pads 6, and the bottoms of the four support pads 6 are provided with anti-slip strips.

[0033] The above technical scheme can achieve the goal of connecting the four hydraulic cylinders 5 on the device to the corresponding oil pumps through the setting of the hydraulic cylinders 5 and the support pads 6, and then the four hydraulic cylinders 5 are pressurized by the oil pump at the same time so that the output ends of the hydraulic cylinders 5 push the support pads 6 to move in the direction of the ground and against the ground, so that the device as a whole is lifted, and then the four hydraulic cylinders 5 are depressurized by the oil pump at the same time so that the output ends of the hydraulic cylinders 5 drive the support pads 6 to retract, thereby driving the device as a whole to descend until the pressure plate 9 contacts the top of the pile and stops the descent of the device. When the ground is uneven, the corresponding hydraulic cylinders 5 can be controlled individually by the oil pump to apply pressure or release pressure to change the height of the corresponding position, thereby completing the adjustment of the horizontality of the device, eliminating the interference of incorrect tilt or inclination on the measurement results, and ensuring reliable data.

[0034] Reference Figure 4 The moving component includes two threaded rods 10 which are symmetrically threadedly connected to the bottom of the two fixed beams 1, the bottom of the four threaded rods 10 are fixedly provided with adjustment blocks, and the bottom of the four adjustment blocks are rotatably provided with moving wheels 12, and the outside of the four threaded rods 10 are threadedly connected with nuts 11.

[0035] The above technical solution can achieve the goal of moving the test machine to the position where it needs to be used through the setting of the moving wheels 12. The moving wheels 12 are super heavy wheels. Through the setting of the threaded rod 10, the nut 11 and the adjustment block, when the road surface is uneven or has a slope, the adjustment block on the threaded rod 10 is rotated by a tool. While rotating, the adjustment block drives the threaded rod 10 to rotate out from the bottom of the fixed beam 1, thereby lifting the corresponding side of the fixed beam 1. Subsequently, the four adjustment blocks are adjusted in turn according to the above operation, thereby adjusting the height of the moving wheels 12, so that the test machine can adapt to different ground conditions, which helps to ensure that the test machine can be moved in different environments, so that the device does not require additional handling equipment or manpower, and improves the flexibility of the device.

[0039] The above technical solution can be achieved by setting up a fixed seat 7, a jack 8 and a pressure plate 9. The bearing plate 9 is against the pile foundation, and axial pressure is applied step by step to the jack 8 through an oil pump. After the detection is completed, the settlement of the pile foundation over time is checked through a displacement sensor, and then the ultimate bearing capacity and bearing capacity characteristic value of the pile foundation are determined based on the recorded load and settlement data.
