Description

Technical Field

[0001] The utility model relates to the technical field of garden landscape road construction, and specifically relates to a road surface bearing capacity detection device. Background Technique

[0002] As a crucial part of civil engineering, the design and construction quality of the subgrade are directly related to the stability and safety of the track or road surface system. The subgrade not only bears the track or road surface structure but also withstands the static and dynamic loads from scenic area vehicles, such as the impact force and braking force generated when scenic area vehicles are driving. Therefore, ensuring that the subgrade has sufficient bearing capacity and stability is the key to ensuring smooth and safe traffic.

[0003] With the increase in traffic flow and the development of transportation technology, the requirements for road bearing capacity are also getting higher and higher. Traditional subgrade detection methods are often time-consuming and laborious, and it is difficult to monitor in real time. Against this background, the road surface bearing capacity detection device has emerged. It uses advanced technical means to quickly and accurately evaluate the bearing capacity and stability of the subgrade.

[0004] The technologies of the road surface bearing capacity detection device mainly include sensor technology, data acquisition and processing technology, wireless communication technology, and cloud computing technology, etc. These technologies work together to achieve real-time monitoring and analysis of the subgrade bearing capacity. For example, through sensors arranged under the road surface, key parameters such as the deformation situation and stress distribution of the subgrade can be monitored in real time; the application of data acquisition and processing technology ensures the accuracy and reliability of the data; the application of wireless communication technology enables the data to be transmitted to the central database in real time, facilitating remote monitoring and management; and the application of cloud computing technology further improves the data processing ability and analysis efficiency, providing data support for scientific decision-making.

[0005] In addition, the road surface bearing capacity detection device can also be equipped with various functional modules according to actual needs, such as temperature monitoring, humidity monitoring, etc., to comprehensively evaluate the working state of the subgrade. The application of these modules further improves the applicability and accuracy of the detection device.

[0006] Existing road surface bearing capacity detection devices generally aim to improve the problem that it is difficult to ensure the stability of the device during use, and the instability of the device will have a certain impact on the detection data, thereby affecting the detection accuracy. For example, a road surface bearing capacity detection device disclosed in the authorized Chinese patent CN216586480U can achieve in-depth detection of the subgrade bearing capacity through the cooperation of structures such as a mounting plate, a movable plate, a fixed rod, a through hole, a hydraulic rod, a pressure sensor, a driving motor, a movable rod, a clamping block, a drill rod, an inserting block, a threaded sleeve, a spiral plate, a fixed frame, a ranging scale, a threaded sleeve, a screw rod, a spiral edge, a baffle, a fixed sleeve, a rotating rod, a handle, a display screen, and a support frame, and ensure the stability during the detection process through a fixing device, thereby improving the detection accuracy.

[0007] However, when the road surface bearing capacity detection device in the above cited document is in use, the weight and volume of the device make it extremely difficult to manually carry. The detection device often weighs dozens of kilograms, and coupled with its huge volume, when the staff needs to move or reposition the device, they have to consume a large amount of physical strength and time. This not only increases the work burden of the staff, but also may lead to a decrease in work efficiency. Secondly, the sharp drill rod on the device may cause accidental injuries to the staff during handling. Moreover, the fixing method of the device also seems not user-friendly. Currently, the fixing device mainly relies on manually rotating the threaded sleeve by hand, which not only takes time, but also requires the operator to have a certain amount of strength and skills. For female staff or individuals with less strength, this process is particularly difficult, which not only increases their work difficulty, but also may affect the accuracy and safety of the detection.

Gear transmission components are connected to both sides of the fixed driving component, and a fixed positioning component is connected to the side of the gear transmission component close to the ground. Two driving boxes 306 that are mirror-symmetrical are fixedly installed on the side of the mounting base plate 1 close to the ground, and a fixed cylinder 307 is fixedly connected to the side of the driving box 306 close to the ground. A lifting driving component is installed in the driving box 306, a threaded pushing component that penetrates the fixed cylinder 307 is connected to the side of the lifting driving component close to the ground, and a moving component is installed on the side of the threaded pushing component close to the ground.

[0035] It should be noted that the fixed driving component includes a dual-axis servo motor 3021, a rotating rod 3022, and a bearing support 3023. One side of the dual-axis servo motor 3021 is fixedly installed on the inner side wall of the mounting control box 301. One end of the rotating rod 3022 is fixedly connected to the output shaft of the dual-axis servo motor 3021, and the opposite end penetrates the bearing support 3023 and is connected to the gear transmission component. One side of the bearing support 3023 is fixedly installed on the inner side wall of the mounting control box 301 through bolts.

[0036] It can be understood that the gear transmission component includes a driving bevel gear 3031 and a driven bevel gear 3032. One side of the driving bevel gear 3031 is fixedly connected to the end of the rotating rod 3022 away from the dual-axis servo motor 3021.

[0037] In addition, the fixed positioning component includes a connecting rod member 3041 and a positioning plate 3042; one end of the connecting rod member 3041 penetrates through the installation control box 301 and extends to the center of one side of the driven bevel gear 3032 and is fixedly connected to the driven bevel gear 3032, and the other end penetrates through the positioning plate 3042 and extends above the ground. The inner side of the positioning plate 3042 is fixedly connected to the outer side of the connecting rod member 3041. An external thread is fixedly connected to the outer side of the end of the connecting rod member 3041 close to the ground. The outer side of the connecting rod member 3041 is rotationally connected to the inside of the installation control box 301 through a bearing, so as to be able to drive the rotating rod member 3022 to rotate under the drive of the dual-axis servo motor 3021, so as to drive the driven bevel gear 3032 meshed on the driving bevel gear 3031 to rotate, and drive the connecting rod member 3041 to rotate, so as to insert the connecting rod member 3041 into the ground through high-speed rotation and be stably fixed under the limiting action of the positioning plate 3042.

[0038] In this embodiment, the lifting drive component includes a worm 3081, a turning handle 3082 and a worm gear 3083; one end of the worm 3081 is rotationally connected to the inner side wall of the drive box 306 through a bearing, and the opposite end penetrates through the drive box 306 and extends to the outside of the drive box 306 and is fixedly connected to the turning handle 3082. The worm 3081 meshes with the worm gear 3083. The turning handle 3082 drives the worm 3081 to rotate, so as to drive the worm gear 3083 to rotate, so as to be able to stably drive the threaded pushing component to rotate.

[0039] It should also be noted that the threaded pushing component includes a threaded rod 3091 and a threaded sleeve 3092; one end of the threaded rod 3091 is fixedly connected to one side of the worm gear 3083, and the opposite end penetrates through the fixed cylinder 307 and extends to the inside of the threaded sleeve 3092 and is threadedly connected to the threaded sleeve 3092. The threaded sleeve 3092 moves on the outside of the threaded rod 3091 under the threaded rotation thrust on the inner side. The outer side of the threaded sleeve 3092 fits and slides with the inner side of the fixed cylinder 307, so as to be able to stably drive the moving component to move up and down.

[0040] It should be further noted that the moving component includes a connecting support plate 3101 and moving wheels 3102; one side of the connecting support plate 3101 is fixedly connected to one side of the threaded sleeve 3092 close to the ground, and one side of the moving wheel 3102 is fixedly installed on one side of the connecting support plate 3101 close to the ground, and the number of the moving wheels 3102 is two and is symmetrically distributed in a mirror image.

Since the threaded sleeve 3092 is slidably connected to the fixed cylinder 307 and can only move within the fixed cylinder 307, the threaded sleeve 3092 performs stable lifting and lowering movement on the outside of the threaded rod 3091 under the thrust of the inner thread rotation. The connecting support plate 3101 moves accordingly and drives the moving wheel 3102 to move. When the moving wheel 3102 is separated from the ground and the connecting rod member 3041 contacts the ground, immediately start the double-shaft servo motor 3021, drive the rotating rod member 3022 to rotate stably under the rotational support of the bearing, and drive the driven bevel gear 3032 engaged with the driving bevel gear 3031 to rotate, so as to drive the connecting rod member 3041 to rotate, insert the connecting rod member 3041 into the ground, and then place it stably under the limiting and positioning action of the positioning plate 3042. Then start the road bearing capacity detection device body 4 to detect the road bearing capacity.
