[0002] Road engineering refers to the entire process of planning, designing, constructing, maintaining, and managing roads, as well as the physical engineering works involved. Like any other type of civil engineering, road engineering has distinct technical, economic, and managerial characteristics.

[0003] The existing published patent, publication number CN211877401U, discloses a detection instrument with a height adjustment structure for road engineering, including a detection instrument, a vertical cylinder, a sampling device body, a first support plate, a second support plate, a telescopic low rod A, a threaded rod A, a connecting rod A, a balance block A, a telescopic low rod B, a threaded rod B, a connecting rod B, and a balance block B. The detection instrument is located at the top of the vertical cylinder, and the sampling device body is located at the bottom of the vertical cylinder. The first support plate and the second support plate are arranged from top to bottom on the assembly of the detection instrument, the vertical cylinder, and the sampling device body. The telescopic low rod A is connected to the right end of the connecting rod A through the threaded rod A, and the balance block A is located at the left end of the connecting rod A. The telescopic low rod B is connected to the left end of the connecting rod B through the threaded rod B, and the balance block B is located at the right end of the connecting rod B.

[0004] The height of this detector requires the simultaneous rotation of the threaded rods on both sides to raise and lower the height, which makes it impractical. Furthermore, the use of a vertical cylinder significantly increases the overall operating and maintenance costs, and it is more prone to damage during use in inclement weather. Summary of the Invention

[0005] This utility model provides a sampling and testing instrument with a height adjustment structure for road engineering. Its purpose is to solve the problems of existing testing instruments that require simultaneous rotation of threaded rods on both sides to raise and lower the height, which is not very practical. In addition, the use of a vertical cylinder greatly increases the overall use and maintenance costs, and makes the instrument more prone to damage in bad weather.

[0006] This utility model provides a sampling and testing instrument with a height-adjustable structure for road engineering, including a base, universal wheels at the bottom of the base, a protective box above the base, a handle at the rear of the protective box, a lifting mechanism inside the protective box, and a testing platform on the lifting mechanism.

[0007] Furthermore, the top of the protective box is hinged with a cover plate, and the contact surface between the cover plate and the protective box is provided with a sealing element.

[0008] By adopting the above technical solution, the protective box can protect the internal testing platform, and the cover can be opened during testing to record the testing data, thus preventing damage to the testing device in severe weather.

[0009] Furthermore, the lifting mechanism includes a sliding column fixedly connected inside the protective box, a rack fixedly connected to the side wall of the sliding column, a sliding sleeve slidably connected to the sliding column, a rotating shaft rotatably connected to the inner side wall of the sliding sleeve, a spur gear fixedly connected to the rotating shaft, and the spur gear meshing with the rack.

[0010] By adopting the above technical solution, the spur gear can slide on the rack, and the sliding sleeve can slide on the sliding column under the drive of the spur gear, so that the detection table on the sliding sleeve can move up and down.

[0011] Furthermore, the lifting mechanism also includes a worm gear fixedly connected to the rotating shaft. The worm gear is located on the side of the spur gear. A worm is provided above the worm gear. The worm gear meshes with the worm. One end of the worm is rotatably connected to the inner wall surface of the sliding sleeve. The other end of the worm passes through the sliding sleeve and the protective box and extends to the outside. A rotating handle is fixedly connected to its end.

[0012] By adopting the above technical solution, when the handle is rotated, the worm can rotate, and the worm drives the worm wheel to rotate. Since the worm wheel and the spur gear are coaxial, the spur gear can rotate synchronously with the worm wheel.

[0013] Furthermore, the detection platform is fixedly connected to the upper surface of the sliding sleeve, and a detection device and a sampling device are respectively installed at the top and bottom of the detection platform.

[0014] By adopting the above technical solution, when the sliding sleeve slides up and down, the detection platform can slide up and down synchronously with the sliding sleeve, thereby performing sampling and detection.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the setting of a protective box, can protect the internal testing platform. The cover can be opened during testing to record the testing data, thus preventing damage to the testing device in severe weather.

[0017] 2. This utility model, through the setting of the lifting mechanism, allows the worm to rotate when the handle is rotated, which in turn drives the worm wheel to rotate. Since the worm wheel and the spur gear are coaxial, the spur gear can rotate synchronously with the worm wheel, and thus the spur gear can slide on the rack. The sliding sleeve can slide on the sliding column under the drive of the spur gear, and thus the detection platform on the sliding sleeve can move up and down, greatly improving practicality and significantly reducing the overall use and maintenance costs.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Reference Figure 1-6 This utility model embodiment proposes a sampling and testing instrument with a height-adjustable structure for road engineering, including a base 1, a caster wheel 2 at the bottom of the base 1, a protective box 3 above the base 1, a cover plate 31 hinged to the top of the protective box 3, and a sealing element at the contact surface between the cover plate 31 and the protective box 3. The protective box 3 can protect the internal testing platform 6, and the cover plate 31 can be opened during testing to record the testing data, thus preventing damage to the testing device in severe weather.

[0029] Reference Figure 1-6 The base 1 is located at the rear of the protective box 3 and has a handle 4. The protective box 3 contains a lifting mechanism 5, which includes a sliding column 51 fixedly connected inside the protective box 3. A rack 52 is fixedly connected to the side wall of the sliding column 51. A sliding sleeve 53 is slidably connected to the sliding column 51. A rotating shaft 54 ​​is rotatably connected to the inner wall of the sliding sleeve 53. A spur gear 55 is fixedly connected to the rotating shaft 54 ​​and meshes with the rack 52. The lifting mechanism 5 also includes a worm gear 56 fixedly connected to the rotating shaft 54. The worm gear 56 is located beside the spur gear 55, and a worm 57 is located above the worm gear 56. The worm gear 56 meshes with the worm 57. One end of the rod 57 is rotatably connected to the inner wall of the sliding sleeve 53. The other end of the worm 57 extends through the sliding sleeve 53 and the protective box 3 to the outside, and a rotating handle 58 is fixedly connected to its end. When the rotating handle 58 is rotated, the worm 57 can rotate, and then the worm 57 drives the worm wheel 56 to rotate. Since the worm wheel 56 is coaxial with the spur gear 55, the spur gear 55 can rotate synchronously with the worm wheel 56. The spur gear 55 can slide on the rack 52, and then the sliding sleeve 53 can slide on the sliding column 51 under the drive of the spur gear 55, and then the detection table 6 on the sliding sleeve 53 can move up and down.

[0030] Reference Figure 1-6The lifting mechanism 5 is equipped with a testing platform 6, which is fixedly connected to the upper surface of the sliding sleeve 53. The top and bottom of the testing platform 6 are respectively equipped with a testing device and a sampling device. The bottom of the protective box 3 and the bottom of the base 1 are equipped with sampling holes, so that the sampling device can pass through the sampling holes to take samples when it descends. When the sliding sleeve 53 slides up and down, the testing platform 6 can slide up and down synchronously with the sliding sleeve 53 to perform sampling and testing.

[0031] The specific implementation method is as follows: When in use, push the device to the sampling and testing location, rotate the handle 58, and then the worm 57 rotates. The worm 57 drives the worm wheel 56 to rotate, and then the spur gear 55, which is coaxial with the worm wheel 56, rotates. Since the spur gear 55 meshes with the rack 52, the spur gear 55 can move up and down on the rack 52, driving the sliding sleeve 53 to slide up and down on the sliding column 51. When it slides to the bottom of the sliding column 51, the sampling device can pass through the sampling hole to successfully collect a sample. After the sampling is completed, open the cover plate 31 so that when the sliding sleeve 53 slides to the top of the sliding column 51, the testing device can pass through the opening at the top of the protective box 3, so that the staff can observe and record the test results.
