Description

Technical Field

[0001] This utility model belongs to the field of highway engineering technology, and in particular relates to a highway soil condition testing device for highway engineering. Background Technology

[0002] In the construction and maintenance of highway engineering, soil condition testing is a crucial step in ensuring project quality. The compaction degree of the soil directly affects the load-bearing capacity and stability of the highway, and scientific analysis of soil samples is also an important means of assessing soil conditions. However, existing highway soil condition testing equipment generally suffers from limited functionality and cumbersome operation.

[0003] Traditional pressure testing devices can only detect the compaction of road soil conditions and cannot be effectively linked with sampling operations. In actual testing work, the testing personnel need to use the pressure testing equipment to complete the compaction test first, and then switch to another device to carry out the sampling operation. This not only wastes a lot of time and manpower, but also the frequent switching of equipment may lead to deviations in the test data and affect the accuracy of the test results.

[0004] Therefore, developing a highway soil condition testing device that can simultaneously perform compaction testing and rapid sampling, while being time-saving, labor-saving, efficient, and convenient, is of significant practical importance. To this end, we provide a highway soil condition testing device for highway engineering to address the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a highway soil condition testing device for highway engineering. Through the cooperation of the support and testing components, it solves the problems of existing testing equipment wasting a lot of time and manpower, and frequent equipment replacement may lead to deviations in the test data, affecting the accuracy of the test results.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a highway soil condition testing device for highway engineering, comprising a support frame. A testing component is fixedly connected to the top of the inner cavity of the support frame. The testing component includes a hydraulic telescopic rod, the output end of which is fixedly connected to a mounting plate.

A drive motor is fixedly connected to the bottom of the mounting plate, and a sampling cylinder is fixedly connected to the output shaft of the drive motor. A second hydraulic telescopic rod is fixedly connected to the bottom of the mounting plate and outside the drive motor. A compaction plate is fixedly connected to the bottom of the second hydraulic telescopic rod, and a pressure sensor is fixedly connected to the bottom of the compaction plate. A second drive motor is fixedly connected to the top side of the sampling cylinder, and a drive gear is fixedly connected to the output shaft of the second drive motor. A driven gear meshes with the surface of the drive gear, and a helical tube is fixedly connected to the shaft of the driven gear. The helical tube is fixedly connected to the top of the sampling cylinder via a bearing. A lead screw is threaded into the inner cavity of the helical tube, and a push plate is fixedly connected to the bottom of the lead screw.

[0008] The present invention is further configured such that the bracket includes a base plate, and support rods are fixedly connected to the four corners of the top of the base plate. A top plate is fixedly connected to the top of the support rods, and a storage battery is fixedly connected to the top of the top plate.

During testing, the steel rod is inserted into the ground, which enhances the stability of the equipment during the testing process, prevents the equipment from shaking due to testing operations, and ensures the reliability of the test data.

[0010] The present invention is further configured such that the top of the base plate has a through hole 1 for passing through the compaction plate, and both sides of the top of the base plate have through holes 2 for passing through the steel rod.

The base plate 11... The top of the plate 11 has a through hole 19 through the compaction plate 28. The top of the bottom plate 11 has through holes 110 through the steel rod 17 on both sides. The bottom of the bottom plate 11 has four casters 111 fixedly connected to each corner. A brake pad is provided on one side of the caster 111.

The front and rear ends of one side of the connecting plate 16 are fixedly connected to limit blocks. The other side of the limit blocks is slidably connected to the inner cavity of the slide groove.

[0032] Specifically: The base plate 11, support rod 12, and top plate 13 combine to form a stable frame, providing reliable support for the entire equipment; the battery 14 and controller 15 are installed on the top plate 13, facilitating power supply and operation control, improving the convenience and stability of the equipment; the hydraulic telescopic rod 18 drives the connecting plate 16 to raise and lower the steel rod 17, inserting the steel rod 17 into the ground during testing, enhancing the stability of the equipment during the testing process, preventing equipment shaking due to testing operations, and ensuring the reliability of the test data; through hole 19 facilitates the up-and-down movement of the compaction plate 28 for pressure testing; through hole 110 facilitates the raising and lowering of the steel rod 17 and its insertion into the ground; the reasonable through hole design makes the movement of each component smoother, ensuring smooth testing operations; and the caster wheel 11... Combined with brake pads, the device can be easily moved between different testing points.

[0033] The working principle of this utility model is as follows: After the equipment reaches the detection point, it moves to a suitable position via the universal wheels 111 and is fixed using brake pads. The controller 15 activates the hydraulic telescopic rod 18, causing the steel rod 17 to be inserted into the ground to fix the equipment. Subsequently, the hydraulic telescopic rod 21 drives the detection component 2 to descend. The ranging transmitter 23 and the ranging receiver 24 monitor the descent distance in real time. The pressure sensor 29 detects the soil compaction data and feeds it back to the controller 15, thus detecting the compaction status of the road. Then, the hydraulic telescopic rod 27 retracts, causing the compaction plate 28 to move upward, exposing the sampling cylinder 26. Simultaneously, drive motor 210 drives screw 214 to rise via gear set transmission, which in turn drives push plate 215 to rise. When sampling cylinder 26 contacts the ground, drive motor 25 starts to drive sampling cylinder 26 to rotate and take samples. After sampling is completed, drive motor 210 and gear set transmission drive screw 214 to fall, which in turn drives push plate 215 to move downward and push the sampled soil sample out of the inner cavity of sampling cylinder 26. After testing is completed, hydraulic telescopic rod 21 retracts to drive testing component 2 to rise, and hydraulic telescopic rod 18 retracts steel rod 17. The equipment can then move to the next testing point to continue working.
