Description

Technical Field

[0001] This utility model belongs to the technical field of roadbed construction equipment, specifically relating to an improved soil roadbed compaction device. Background Technology

[0002] Improved soil subgrades possess advantages such as high load-bearing capacity and good stability, and are widely used in the construction of transportation infrastructure such as highways and railways. The quality of compaction directly determines the service life of the subsequent pavement structure and driving safety. Insufficient compaction can easily lead to subgrade settlement and deformation; excessive compaction can damage the improved soil particles, also affecting the overall strength of the subgrade.

[0003] However, traditional roadbed compaction devices lack real-time and comprehensive parameter monitoring capabilities. Most devices rely solely on the operator's experience to judge the compaction effect or can only monitor a single parameter (such as compaction pressure), failing to simultaneously grasp key indicators such as roadbed settlement displacement and improved soil moisture, resulting in blind spots in compaction quality control. Utility Model Content

[0004] The purpose of this invention is to provide an improved subgrade compaction device to solve the problem mentioned in the background art of the lack of real-time and comprehensive parameter monitoring capabilities in traditional subgrade compaction devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an improved soil subgrade compaction device, comprising a roller body, a mounting frame, and rollers. The mounting frame is fixed to one side of the roller body, and the rollers are rotatably connected within the mounting frame. A pressure detection component is mounted on the rollers. A displacement detection component and a humidity detection component are respectively mounted on the mounting frame. The pressure detection component consists of a pressure sensor and a wear-resistant ceramic cover plate. The displacement detection component consists of a protective shell and a displacement sensor. The humidity detection component consists of a mounting box, an electric telescopic rod, and a humidity sensor probe.

[0006] In a further embodiment, the roller has an embedded mounting groove, the pressure sensor is embedded in the mounting groove, the wear-resistant ceramic cover plate is fixed to the opening of the mounting groove and is flush with the surface of the roller, and an elastic buffer pad is provided between the pressure sensor and the wear-resistant ceramic cover plate.

[0007] In a further embodiment, the protective shell is fixed on the mounting bracket, the displacement sensor is disposed inside the protective shell, and a rubber buffer seat is sleeved on the outside of the displacement sensor. Two sets of symmetrically distributed spring shock absorbers are provided on the inner side of the rubber buffer seat.

[0008] In a further embodiment, the mounting box is fixed on the mounting frame, the electric telescopic rod is installed inside the mounting box, and the output end of the electric telescopic rod is fixed with a mounting plate that is fixedly connected to the humidity sensor probe.

[0009] In a further embodiment, the outer walls of the mounting plate are provided with rotating grooves, and sliding balls are rolled in the rotating grooves. The inner walls of the mounting box are provided with limiting grooves for the sliding balls to roll.

[0010] The technical effects and advantages of this utility model are as follows: This improved soil subgrade compaction device, through the coordinated work of pressure detection components, displacement detection components, and humidity detection components, can simultaneously collect three key parameters of the improved soil subgrade in real time: compaction pressure, settlement displacement, and soil moisture. This avoids the quality blind spots caused by traditional single-parameter monitoring. Staff can comprehensively judge the subgrade compaction status through data to ensure that the subgrade compaction quality meets the standards. In the pressure detection assembly, the wear-resistant ceramic cover plate is flush with the roller surface, which not only avoids the pressure sensor from directly rubbing against the improved soil, but also ensures accurate transmission of compaction pressure. The elastic buffer pad can absorb the impact load during the compaction process and prevent the pressure sensor from being damaged by instantaneous impact. The protective shell of the displacement detection component can isolate external dust and gravel, while the internal rubber buffer seat and symmetrical spring shock absorbers can offset the impact of road roller vibration on the displacement sensor, ensuring detection accuracy while reducing sensor wear. The humidity sensor probe is stored in the mounting box, which can prevent collision damage when not in use. The overall structure greatly improves the durability of the sensor and reduces equipment maintenance costs. The humidity detection component uses an electric telescopic rod to drive the mounting plate, which in turn moves the humidity sensor probe. The probe insertion depth can be flexibly adjusted according to the compaction depth and stage of the improved soil subgrade, enabling humidity detection at different locations. This overcomes the limitation of traditional manual sampling, which can only detect surface humidity. This improved soil subgrade compaction device, through the coordinated work of multiple sensors, can monitor various key parameters of the improved soil subgrade in real time and comprehensively during the compaction process, ensuring that the improved soil subgrade achieves the best compaction effect and avoiding subgrade quality problems caused by insufficient or excessive compaction.

[0019] Working principle: In operation, the improved soil subgrade compaction device drives the roller 3 in the mounting frame 2 on one side to roll. The roller 3 contacts the improved soil subgrade and applies pressure to complete the compaction. During the compaction process, the pressure sensor 4 embedded in the mounting groove on the roller 3 senses the real-time compaction pressure of the roller 3 on the subgrade through the elastic buffer pad 5 and the wear-resistant ceramic cover plate 6 above. At the same time, the displacement sensor 9 in the protective shell 7 on the mounting frame 2 monitors the settlement displacement of the subgrade under the compaction action in real time. The rubber buffer seat 8 and two sets of symmetrically distributed spring shock absorbers 10 inside the protective shell 7 can effectively offset the vibration generated by the roller body 1 during operation, avoid vibration interference with the displacement detection data, and ensure detection accuracy. The electric telescopic rod 12 inside the mounting box 11 on the mounting frame 2 is activated, driving the connected mounting plate 13 to extend the humidity sensor probe 14 out of the mounting box 11, allowing the humidity sensor probe 14 to insert into the improved soil and detect the soil moisture at different depths. The compaction pressure, settlement displacement, and soil moisture data collected by each sensor are transmitted in real time to the control box of the roller body 1. After being analyzed and processed by the data processing module, the data is sent to the control terminal via the wireless transmission module. Based on the real-time parameters displayed on the terminal, if the compaction pressure is insufficient, the roller counterweight or travel speed is adjusted to increase the pressure; if the displacement is abnormal, the flatness of the subgrade surface is checked and corrected in time; if the humidity is too high, compaction is suspended for drying; if the humidity is too low, water is sprinkled to replenish moisture. Through real-time control, the improved soil subgrade is always kept under the best compaction conditions, ultimately achieving the ideal compaction effect and avoiding subgrade quality problems caused by parameter malfunction.
