Technical Field

[0001] The utility model relates to the technical field of foundation detection, in particular to an engineering foundation detection and measurement tool. Background Art

[0002] The foundation refers to the base of a building or other engineering structure, which is used to support and transfer loads to the foundation soil. The main function of the foundation is to ensure the stability and safety of the building or structure. The foundation can be divided into two categories: shallow foundation and deep foundation. The design and construction of the foundation need to take into account the bearing capacity, settlement performance, groundwater conditions and the impact of natural disasters such as earthquakes. In foundation engineering, foundation survey, foundation design, foundation construction and foundation monitoring are usually required to ensure the stability and safety of the foundation.

[0003] After searching, the Chinese patent with announcement number: CN212612384U discloses a foundation detection device for construction engineering, including a bottom plate, guard plates are fixedly installed on the left and right sides of the top of the bottom plate, a top plate is fixedly installed on the top of the guard plate, a chassis is fixedly installed on the top of the top plate, a second motor is fixedly installed in the inner cavity of the chassis, a threaded rod is installed at the output end of the second motor, a screw block is threadedly connected to the surface of the threaded rod through a screw groove, a first motor is fixedly installed on the left side of the screw block, a sampling barrel is installed at the output end of the first motor, a reserved groove is opened in the inner cavity of the bottom plate, and an electric telescopic rod is fixedly installed around the bottom of the bottom plate. The utility model is provided with a bottom plate, a wheel frame, a sampling barrel, a first motor, a slider, a top plate, a second motor, a threaded rod, a screw block, a guard plate, a slide groove, an electric telescopic rod, a fixing plate, a roller and a screw groove, which solves the problem that the existing sampling device is not easy to move and fix, and has poor stability.

[0004] In this patent, foundation sampling requires the use of two motors to complete the lifting and rotating sampling of the sampling tube respectively. The two motors will cause a problem of high power consumption to a certain extent, and the foundation inspection sample cannot be completely pushed out of the sampling tube after sampling. Utility Model Content

[0005] In view of the existing patents, foundation sampling requires the use of two motors to respectively complete the lifting and rotating sampling of the sampling tube. The two motors will lead to a problem of large power consumption to a certain extent, and the sampling tube cannot completely push the foundation test samples taken after sampling. The utility model provides an engineering foundation detection and measurement tool.

[0006] The technical solution adopted by the utility model is: an engineering foundation detection and measurement tool, including a moving seat, a sampling tube, a support column and a self-locking universal wheel, the outer surface of the support column is equipped with a sampling and pushing assembly, the sampling and pushing assembly includes a sample pushing part and a sampling part, the sample pushing part includes a connecting plate, a connecting column, a sample pushing plate and a scraping strip, the outer surface of the sampling tube is provided with a threaded groove, the sampling tube is connected to the inner thread of the inner thread connecting tube through the threaded groove on the outer surface, and the sampling tube is driven by a motor to move downward and insert into the foundation for sampling when rotating, and the lifting and lowering of the sampling tube for sampling can be realized by a motor, which helps to reduce power consumption.

[0007] Furthermore, the connecting plate is fixedly mounted on one end of the supporting column, and one end of the connecting column is fixedly mounted on the bottom of the connecting plate. The sample push plate is placed in the sampling tube through the connecting column without hindering the lifting and lowering of the sampling tube for sampling.

[0008] Furthermore, the other end of the connecting column is fixedly connected to the sample pushing plate, and the sample pushing plate is located inside the sampling barrel, and the scraper bar is fixedly installed on the bottom of the movable seat by bolts. After the foundation sample is taken out from the sampling barrel, it continues to rise. Because the position of the sample pushing plate is fixed, when the top of the taken foundation sample rises to the bottom of the sample pushing plate, it will be restricted by the sample pushing plate and will not continue to rise with the sampling barrel, thereby separating the sampling barrel from the internal sample during the rising process.

[0009] Furthermore, the sampling component includes a lifting mounting plate, a motor, an internal threaded connecting tube and a gear. The lifting mounting plate is slidably mounted on the outer surface of the support column, and the motor is fixedly mounted on the bottom of the lifting mounting plate. The motor is connected to an external control switch through existing technology, and there are two support columns, which are symmetrically arranged on both sides of the top of the moving seat.

[0010] Furthermore, a gear 2 is fixedly installed at one end of the motor output shaft, the gear 1 is fixedly installed at one end of the sampling tube, and the gear 1 and the gear 2 are meshed with each other. The gear 2 drives the gear 1 to rotate through the meshing teeth, thereby driving the sampling tube to rotate. The sampling tube realizes lifting movement through the threaded connection of the threaded groove and the internal threaded connecting tube. The lifting mounting plate will rise and fall accordingly under the limit guide of the support column, so that the gear 1 and the gear 2 always remain in a meshing state and will not separate.

[0011] Furthermore, the sampling tube is rotatably installed inside the lifting mounting plate, a sampling hole is opened on the top of the movable seat, and the internal threaded connecting tube is fixedly installed inside the sampling hole. The rotating connection between the sampling tube and the lifting mounting plate can maintain the position of the sampling tube in the lifting mounting plate stable and realize the lifting and lowering of the lifting mounting plate on the support column.

[0012] Furthermore, the self-locking universal wheel is fixedly installed at the bottom of the moving seat, and the support column is fixedly installed at the top of the moving seat. The self-locking function of the self-locking universal wheel can keep the position of the moving seat stable.

[0013] The beneficial effect of the utility model is that compared with the prior art, in the utility model, the lifting and rotating sampling of the sampling tube and the complete sampling of foundation detection samples can be achieved simultaneously through the motor drive in the sampling piece, which helps to reduce power consumption.

Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The following is combined with Figure 1-4 The utility model is further described.

[0022] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: an engineering foundation detection and measurement tool.

[0023] The specific technical solution includes a movable seat 1, a sampling tube 2, a support column 3 and a self-locking universal wheel 4. The outer surface of the support column 3 is provided with a sampling sample pushing assembly 5. The sampling sample pushing assembly 5 includes a sample pushing part 501 and a sampling part 502. The sample pushing part 501 includes a connecting plate 5011, a connecting column 5012, a sample pushing plate 5013 and a scraping strip 5014. The outer surface of the sampling tube 2 is provided with a threaded groove 6. Driven by a motor 5022, the sampling tube 2 can be lifted and rotated for sampling and sample discharging at the same time, which helps to reduce power consumption.

[0024] The connecting plate 5011 is fixedly installed on one end of the supporting column 3, and one end of the connecting column 5012 is fixedly installed on the bottom of the connecting plate 5011, and the other end of the connecting column 5012 is fixedly connected to the sample pushing plate 5013, and the sample pushing plate 5013 is located inside the sampling tube 2, and the scraper bar 5014 is fixedly installed on the bottom of the moving seat 1 by bolts. During the upward movement of the sampling tube 2 after sampling, if some foundation debris is stuck inside the threaded groove 6, it will be scraped off by the scraper bar 5014 before entering the internal threaded connecting tube 5023, so as to prevent the debris from being stuck between the internal threaded connecting tube 5023 and the sampling tube 2 and affecting the normal lifting efficiency of the sampling tube 2.

[0025] The sampling component 502 includes a lifting mounting plate 5021, a motor 5022, an internal threaded connecting tube 5023 and a gear 1 5024. The lifting mounting plate 5021 is slidably mounted on the outer surface of the support column 3, and the motor 5022 is fixedly mounted on the bottom of the lifting mounting plate 5021. One end of the output shaft of the motor 5022 is fixedly mounted with a gear 2 5025. The gear 1 5024 is fixedly mounted on one end of the sampling tube 2, and the gear 1 5024 and the gear 2 5025 are meshed with each other. The gear 2 5025 drives the gear 1 5024 to rotate through the meshing teeth, thereby driving the sampling tube 2 to rotate. During the rotation of the sampling tube 2, the downward movement is realized through the threaded connection between the threaded groove 6 and the internal threaded connecting tube 5023, and the sliding connection between the lifting mounting plate 5021 and the support column 3. During the downward movement, the lifting mounting plate 5021 moves up and down on the support column 3.

[0026] The sampling tube 2 is rotatably installed inside the lifting mounting plate 5021, a sampling hole 7 is opened on the top of the moving seat 1, the internal threaded connecting tube 5023 is fixedly installed inside the sampling hole 7, the self-locking universal wheel 4 is fixedly installed on the bottom of the moving seat 1, and the support column 3 is fixedly installed on the top of the moving seat 1. After the moving seat 1 is moved to the designated foundation detection position, the position of the moving seat 1 is stabilized by locking it through the self-locking universal wheel 4 to prevent the device from accidentally moving when sampling the foundation and affecting the normal sampling work.

[0027] In order for those skilled in the art to fully understand the technical solution, this application makes the following overall summary:

[0028] When in use, the motor 5022 is started to drive the gear 2 5025 to rotate, and the gear 2 5025 drives the sampling tube 2 to rotate through the gear 1 5024. The sampling tube 2 and the lifting mounting plate 5021 move downward together under the drive of the motor 5022 until the sampling tube 2 is inserted into the foundation detection position to take a sample. After sampling, the motor 5022 is started to reverse, and the sampling tube 2 reverses accordingly, and is screwed together with the threaded groove 6 and the internal threaded connecting tube 5023 to move upward to take out the sample, and the lifting mounting plate 5021 moves upward accordingly until the top of the sample inside the sampling tube 2 moves to the bottom of the sample pushing plate 5013. The sample is limited by the sample pushing plate 5013 and will not continue to rise with the sampling tube 2. It will be pushed out of the sampling tube 2 during the continuous rising process of the sampling tube 2, thereby realizing rapid sampling. Driven by one motor 5022, the sampling tube 2 can be lifted and rotated for sampling and sampling at the same time, which helps to reduce power consumption.
