Description

Technical Field

[0001] This utility model relates to the field of foundation testing technology, and in particular to a portable foundation testing device. Background Technology

[0002] The foundation refers to the soil or rock mass supporting a building. Soil layers used as building foundations are classified as rock, gravelly soil, sandy soil, silty soil, cohesive soil, and artificial fill. Foundations are divided into two categories: natural foundations and artificial foundations (composite foundations). Natural foundations are natural soil layers that do not require reinforcement, while artificial foundations require reinforcement treatment, commonly including stone chip cushion layers, sand cushion layers, and mixed lime-soil backfill followed by compaction. The foundation bears the entire load of the building; therefore, during the construction phase of an engineering project, it is necessary to use foundation testing devices to test the foundation, such as bearing capacity and settlement, to determine whether the foundation soil meets design requirements and ensure the safety of construction. Foundation testing devices are specialized equipment used to evaluate the bearing capacity, integrity, and uniformity of foundations, and are widely used in the foundation investigation and quality acceptance stages of building, highway, railway, and bridge construction projects.

[0003] However, some existing foundation testing devices are too large to be easily carried or moved, and it is inconvenient to adjust the testing position when multiple points of the foundation need to be tested, making them very inconvenient to use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a portable foundation testing device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a portable foundation testing device, including a testing bracket for support and fixation. A testing component for foundation testing is fixedly installed inside the testing bracket. A connecting seat for support and connection is fixedly installed at the bottom of the testing bracket. A fixed base rod for storage and adjustment is movably connected inside the connecting seat. A safety baffle for shielding and protecting the testing component is rotatably connected to the bottom of the fixed base rod. A fastening block for fixing the position of the safety baffle is fixedly installed at one end of the safety baffle. A folding and storage wheel frame is provided on one side of the safety baffle. A locking block for positioning the wheel frame is fixedly installed inside the wheel frame.

[0006] Preferably, in any of the above embodiments, the four corners of the detection bracket are provided with support guide rods, the inside of the support guide rods and the connecting seat is provided with a storage groove for storing the fixed base rod, and the top of the support guide rod is provided with a slot for storing the fastening block.

[0007] The above technical solution is adopted: the support guide rods at the four corners of the detection bracket provide vertical support for the detection components, the internal storage groove is used to store the fixed base rod, and the top slot of the support guide rod can store the fastening block, which facilitates the folding and storage of the safety baffle, ensuring that the detection device has a compact structure and reduces its volume during transportation.

[0008] Preferably, in any of the above embodiments, the connecting seat includes a fixed seat for support, a high-strength spring for support, and a positioning block for engaging the fixed base rod. The fixed seat is fixedly installed at the bottom of the detection bracket, and a high-strength spring is fixedly installed inside the fixed seat. One end of the high-strength spring is fixedly installed with a positioning block that moves inside the fixed seat.

[0009] The above technical solution is adopted: the fixed seat of the connecting seat is installed at the bottom of the testing bracket, and the high-strength spring pushes the positioning block into the slot of the fixed base rod. When it is necessary to adjust the height of the fixed base rod, the positioning block is stretched to compress the high-strength spring, so that the fixed base rod can be pulled out or inserted from the storage slot, realizing stepless adjustment of the working height of the testing component to adapt to the height requirements of different foundation testing scenarios.

[0010] Preferably, in any of the above embodiments, the fixed base rod has an internal slot for engaging with the positioning block, the bottom of the fixed base rod has a large base plate, and the base plate has rotating grooves around its perimeter for supporting the safety baffle.

[0011] The above technical solution is adopted: the large-size base plate at the bottom of the fixed base rod increases the support area and improves the stability of the detection device. The rotating groove around the base plate provides rotation support for the safety baffle, allowing the safety baffle to rotate around the base plate, forming a protective barrier for the detection components and preventing debris from hitting the equipment during the detection process.

[0012] Preferably, one end of the safety baffle is provided with a movable groove for supporting the fastening block. The fastening block includes a fastening spring for support and a clamping block for limiting the position of the safety baffle. The fastening spring is fixedly installed inside the safety baffle, and one end of the fastening spring is fixedly installed with a clamping block that moves inside the safety baffle.

[0013] The above technical solution is adopted: the safety baffle is installed on the base plate through the rotating groove. The fastening spring in its movable groove pushes the clamping block to embed into the top groove of the support guide rod, thereby realizing the vertical locking of the safety baffle. When it is necessary to unfold the safety baffle, press the clamping block to compress the fastening spring, and the safety baffle can be rotated around the base plate to a horizontal position, fitting against the bottom of the fixed base rod and the ground, thus improving the stability of the placement.

[0014] Preferably, in any of the above embodiments, the movable wheel frame includes a wheel seat for flipping support and a movable wheel for rolling, wherein the wheel seat is rotatably connected to one end of the detection bracket, and the movable wheel is rotatably connected to one end of the wheel seat.

[0015] The above technical solution employs a wheel base that is rotatably connected to the testing bracket via a pin, allowing it to be flipped to a horizontal or vertical position. When horizontal, the moving wheels contact the ground, facilitating the movement of the testing device; when vertical, the moving wheel frame fits against the side of the testing bracket, reducing the floor space required. The moving wheels are made of wear-resistant rubber, adaptable to various ground environments.

[0016] Preferably, in any of the above embodiments, the locking block includes a locking spring for support and a pulling block for locking the wheel seat. The locking spring is fixedly installed inside the wheel seat, and one end of the locking spring is fixedly installed with a pulling block that moves inside the wheel seat.

[0017] The above technical solution is adopted: the locking spring of the locking block pushes the pulling block into the positioning hole of the detection bracket, fixing the rotation angle of the wheel seat. When it is necessary to move the detection device, the pulling block is pulled to compress the locking spring, releasing the lock, and the wheel seat can be rotated to a horizontal position. After moving into place, the pulling block is released, and the pulling block automatically engages into the positioning hole under the action of the locking spring, locking the position of the moving wheel frame and preventing the device from sliding during detection.

[0018] The combination of the movable wheel frame and the fixed base pole allows the testing device to be pushed by the wheels when moving and supported by the fixed base pole and the base plate during testing, ensuring the stability of the test data. The safety baffle can be used as a protective fence during testing to prevent personnel from accidentally touching the testing components and improve the safety of the construction site. The testing bracket, fixed base pole, safety baffle and movable wheel frame can all be folded and stored, reducing the size of the device after storage, which is convenient for manual handling or vehicle transportation.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0020] 1. A rotating and retractable movable wheel frame is installed at one end of the testing bracket that supports the testing component, allowing the testing bracket to move.

[0033] The above technical solution is adopted: the support guide rods at the four corners of the detection bracket 1 provide vertical support for the detection component 2, and the internal storage groove is used to store the fixed base rod 4. The top slot of the support guide rod can store the fastening block 6, which facilitates the folding and storage of the safety baffle 5, ensuring that the detection device has a compact structure and reduces its volume during transportation.

[0034] Preferably, the connecting seat 3 includes a fixed seat 31 for support, a high-strength spring 32 for support, and a positioning block 33 for engaging the fixed bottom rod 4. The fixed seat 31 is fixedly installed at the bottom of the detection bracket 1. The high-strength spring 32 is fixedly installed inside the fixed seat 31. One end of the high-strength spring 32 is fixedly installed with the positioning block 33 that moves inside the fixed seat 31.

[0035] Using the above technical solution: the fixing seat 31 of the connecting seat 3 is installed at the bottom of the detection bracket 1, and the high-strength spring 32 pushes the positioning block 33 into the slot of the fixing base rod 4. When it is necessary to adjust the height of the fixing base rod 4, the positioning block 33 is stretched to compress the high-strength spring 32, so that the fixing base rod 4 can be pulled out or inserted from the storage slot, thereby realizing stepless adjustment of the working height of the detection component 2 and adapting to the height requirements of different foundation detection scenarios.

[0036] Preferably, in any of the above solutions, the fixed base rod 4 has a slot inside that engages with the positioning block 33, and the bottom of the fixed base rod 4 has a large base plate, with rotating grooves around the base plate to support the safety baffle 5.

[0037] The above technical solution is adopted: the large-size base plate at the bottom of the fixed base rod 4 increases the support area and improves the stability of the detection device.
