Description

Technical Field

[0001] The invention belongs to the technical field of earth-rock dam roller devices, and in particular relates to a real-time monitoring and control device for the compaction quality of earth-rock dam materials. Background Art

[0002] In the field of water conservancy and hydropower engineering, earth-rock dams are important hydraulic structures, and the compaction quality of their dam materials is directly related to the overall stability and service life of the dam body. Earth-rock dams generally refer to water retaining dams built with local soil, stone or mixed materials through dumping, rolling and other methods. When the dam body material is mainly soil and gravel, it is called an earth dam; when it is mainly composed of slag, pebbles, and blasted stones, it is called a rockfill dam; when both types of local materials account for a considerable proportion, it is called an earth-rock mixed dam. Earth-rock dams are one of the oldest types of dams.

[0003] However, during the construction of earth-rock dams, the compaction quality of dam materials is often affected by many factors, such as the nature of the filling materials, the filling process, the performance of the rolling machinery, and the skills of the operators. Therefore, how to control and accurately monitor the compaction quality of earth-rock dam materials has become a key issue that needs to be solved in the construction of water conservancy and hydropower projects.

[0004] The traditional dam material compaction quality monitoring method of the test pit test adopted in the earth-rock dam construction specifications is convenient and feasible, but it has the disadvantages of being time-consuming, poorly representative, unable to achieve full coverage detection, and being somewhat destructive to the construction surface.

[0005] In addition, when the number of compaction passes of traditional earth-rock dam materials approaches the target value, there may be a situation where the front section of a road surface has reached the target value, but the rear section has not yet reached the target compaction due to different particle size distributions. It is necessary to reduce the exciting force appropriately by the roller to avoid damage to the dam body caused by excessive compaction. When the pressure needs to be increased, the exciting force can be increased in real time to ensure that the compaction of the road surface is uniform.

[0006] In order to solve this problem, the existing patent "201310036698.8" "Real-time Monitoring Device for Compacted Earth-Rock Dam Material" adopts the following technical solution: a real-time monitoring device for compacted earth-rock dam material quality: including a roller acceleration monitoring module, a GPS positioning module, and a data processing module. The acceleration sensor of the roller acceleration monitoring module is installed on the vibrating wheel of the roller and does not rotate with the vibrating wheel; the acceleration spectrum data and the current sampling time are transmitted to the data processing module. Although the device can realize the remote transmission of compacted quality indicators, it can also realize the integrated quality management of earth-rock dam construction of "driver-contractor-supervisor-owner".

[0007] However, the following issues still exist:

[0008] The function that this device can achieve is to measure and feedback the compaction index, thereby realizing the integrated "driver-contractor-supervisor-owner" earth-rock dam construction quality management. The quality management process is long and cumbersome, and it cannot achieve real-time feedback and control of the compaction quality of earth-rock dam materials, which consumes a lot of manpower and a large workload.

[0009] In recent years, with the rapid development of sensor technology, data processing technology and automatic control technology, real-time monitoring devices have been widely used in the compaction quality monitoring of earth-rock dam materials, which can further solve the above-mentioned problems and realize real-time monitoring and control of the compaction of earth-rock dam materials. Summary of the invention

[0010] In view of the technical problems in the above-mentioned prior art that the compaction quality cannot be intuitively reflected and the real-time feedback and control of the compaction quality of earth-rock dam materials cannot be achieved, and the manpower consumption and workload are large, the present invention provides the following technical ideas and achieves excellent technical effects.

[0011] Technical idea: The present invention can realize real-time monitoring and feedback of the compaction quality of earth-rock dam materials by setting up a real-time monitoring and control device for actual quality. The controller can calculate and analyze the monitoring parameters in real time to provide real-time feedback for construction personnel, and can also provide a basis for on-site quality control personnel; at the same time, the exciting force can be intelligently controlled. When the dam material changes, the device can automatically sense it and adjust the output of the exciting force accordingly to ensure that the compaction quality of the dam material is always maintained in the best state. Through real-time monitoring and intelligent control, the device can significantly improve the efficiency and convenience of earth-rock dam material compaction construction. Construction personnel can adjust the construction process and parameters in time according to the real-time monitoring data to ensure that the compaction quality of the dam material meets the design requirements. Compared with the existing devices, the device of the present invention can respond to the compaction quality very intuitively and in real time, and the measurement process is very simple, and the force measuring device is simple and low-cost, and can be widely used in engineering fields.

[0063] During the construction of earth-rock dams, the compaction quality of the dam materials needs to be monitored by special quality control personnel. After monitoring, the data is fed back to the engineering project department. The engineering project department further determines the compaction process parameters, such as compaction variables and roller agitation force, and notifies the driver for execution.

[0064] The entire process is cumbersome and cannot provide real-time feedback on the compaction quality to achieve accurate quality control. At the same time, it reduces the quality control process and enables real-time monitoring and control of the dam material compaction quality at the driver's end.

[0066] Embodiment 1:

[0067] A real-time monitoring and control device for compaction quality of earth-rock dam materials, comprising a main board 1, and a driving mechanism and a controller 2 arranged on the main board 1;

[0068] The driving mechanism comprises a driving motor 3, a roller assembly and a rear wheel assembly. The driving motor 3 is arranged on the main board 1, and the output end of the motor drives the roller assembly and the rear wheel assembly.

[0069] The roller assembly includes a No. 1 transmission belt 4, a main shaft 5, a mounting frame 7, a frame 8 and an eccentric roller 9. A rectangular mounting block 10 and a driving motor 3 are fixedly arranged on the upper end surface of the main board 1. The main shaft 5 passes through the mounting block 10 and is rotatably arranged. The No. 1 transmission belt 4 is arranged on the main shaft 5 and the output end of the driving motor 3. The driving motor 3 rotates, driving the No. 1 transmission belt 4 to transmit, and then driving the main shaft 5 to rotate.

[0070] Furthermore, a power supply 19 is provided on the mainboard 1 , and the power supply 19 provides power to the driving motor 3 and the controller 2 .

[0071] A No. 1 connecting plate 6 is provided at both ends of the main shaft 5, the frame 8 is fixedly mounted on the main board 1, and the mounting frame 7 is slidably mounted on the frame 8. Specifically, U-shaped arms are provided at both ends of the frame 8, a vertical positioning rod 801 is fixedly provided on the U-shaped arm, and two arms of the mounting frame 7 are slidably provided on the positioning rod 801.

[0072] The eccentric roller 9 is rotatably mounted in a U-shaped mounting frame 7 , and an eccentric block 901 is arranged in the eccentric roller 9 .

[0073] When the eccentric roller 9 rotates to compact the dam material, up and down fluctuations will occur. In order to avoid rigid vibration, the U-shaped arms of the mounting frame 7 at both ends of the frame 8 move up and down.

[0074] A No. 2 connection plate 11 is fixedly arranged on both sides of the eccentric roller 9, and a No. 2 transmission belt 12 is arranged on the No. 1 connection plate 6 and the No. 2 connection plate 11. The main shaft 5 rotates to drive the No. 1 connection plate 6 to rotate, and the No. 1 connection plate 6 further drives the No. 2 transmission belt 12 to drive, and the No. 2 transmission belt 12 drives the No. 2 connection plate 11 to rotate, thereby driving the eccentric roller 9 to rotate, so as to realize the compaction of the earth-rock dam material.

[0075] An auxiliary frame 15 is fixedly arranged on the lower end surface of the main board 1, and an auxiliary wheel 16 is arranged on the auxiliary frame 15. The arrangement of the auxiliary wheel 16 can ensure the steady-state operation of the entire device.

[0076] The rear wheel assembly includes a rotating shaft 13 and a No. 3 transmission belt 14. A rotating hole is opened at the rear end of the main board 1. The rotating shaft 13 is rotatably set in the rotating hole at the rear end of the main board 1.

[0077] The monitoring module includes a front-end force measuring unit 17 and a rear-end force measuring unit 18 . The front-end force measuring unit 17 is mounted on the lower end surface of the mounting frame 7 , and the rear-end force measuring unit 18 is mounted on the lower end surface of the mainboard 1 .

[0078] The front force measuring unit 17 and the rear force measuring unit 18 are the same device. When working, the front force measuring unit 17 and the rear force measuring unit 18 can be extended. After being extended to a certain length, they are in contact with the surface of the earth-rock dam and receive a reaction force. The reaction force is the measured force value. According to the principle of force, the force is the measured resistance of the earth-rock dam material, which reflects the compaction of the earth-rock dam. The higher the compaction of the earth-rock dam, the greater the reaction, and the smaller the compaction of the earth-rock dam, the smaller the reaction force. Fig.10 As shown, F1 is the force measured by the front-end force measuring unit, and F2 is the force measured by the rear-end force measuring unit.

[0079] The controller 2 is arranged on the main board 1, and includes a monitoring module and a control module, to monitor and control the driving mechanism. The front force measuring unit 17 and the rear force measuring unit 18 monitor the compaction state parameters of the dam material, and the compaction state parameters include the compaction depth and the number of compaction passes.

[0080] The control module calculates and analyzes the compaction state parameters in real time according to the feedback from the monitoring module, and adaptively adjusts the output exciting force and controls the number of compaction passes. The control principle of the control module is based on the monitoring control method of the second embodiment.

[0081] Furthermore, during each rolling process, the control module can record the number of times each rolling is performed.

[0082] Embodiment 2:

[0083] A monitoring and control method for a real-time monitoring and control device for compaction quality of earth-rock dam materials, comprising:

[0084] S1: Start running, the default initial value gives the maximum throttle opening, so that the exciting force of the eccentric roller 9 is the maximum;

[0085] S2: The monitoring module collects the displacement difference Δh when the roller starts rolling. The eccentric roller 9 of the roller uses the same force before and after rolling. The front force measuring unit 17 measures the uncompacted earth-rock dam to obtain the displacement value before compaction. The rear force measuring unit 18 measures the compacted earth-rock dam to obtain the displacement value after compaction. The displacement value before compaction is subtracted from the displacement value after compaction to obtain the displacement difference Δh. Definition h max It is the initial soil softness, which is obtained by measuring the uncompacted earth-rock dam with the set maximum force by the front-end force measuring unit 17.

[0086] If Δh<0.1h max , the earth-rock dam begins to be in a hard state, and the exciting force F is controlled according to the value of ΔF J ; Specifically:

[0087] If Δh<0.1h max , then θ=K1ΔF, where K1 is the proportional constant;

[0088] Further, construct the exciting force F J The solution formula is:

[0089]

[0090] Among them, R is the large radius of the eccentric block, r is the small radius of the eccentric block, B is the thickness of the eccentric block, ρ is the density of the eccentric block, K2 is the proportional constant, Rd is the resistance, θ is the throttle opening, θ max is the maximum throttle opening, is the magnetic flux, and I is the input current.

[0091] If Δh≧0.1h max , then the roller is rolled at the maximum throttle opening, that is: θ = θ max ; Then the maximum exciting force is used for compaction:

[0092] S3: Calculate the difference in compaction:

[0093] ΔF / ΔF max

[0094] Wherein, ΔF=K1F1-K1F2, F1 is the force measured by the front force measuring unit, and F2 is the force measured by the rear force measuring unit;

[0095] S4: If ΔF / ΔF max <2%, it means the compaction meets the standard and the roller is completed;

[0096] If ΔF / ΔF max ≧2%, then return to S2 and recycle.

[0097] Due to the inconsistency of particle size, the compaction degree will be different. This system can prevent partial over-pressing. By judging the ratio of ΔF and the maximum ΔF, the compaction degree can be known. When the ratio is greater than 2%, the x value is the number of rolling times plus 1, and the judgment is repeated and the cycle is repeated until the ratio is less than 2%, which proves that the compaction meets the standard and the rolling can be completed.

[0098] In the above method, the derivation process of the algorithm is:

[0099]

[0100] θ=K1ΔF

[0101] in, is the angular velocity of the eccentric mass, θ is the throttle opening, θ max is the maximum throttle opening, where N is the speed, U is the power supply voltage, and E b is the back electromotive force, K1 and K2 are proportional constants, is the magnetic flux, Rd is the resistance, I is the input current, is the angular velocity of the eccentric mass, F J Exciting force.

[0102] R is the large radius of the eccentric block, r is the small radius of the eccentric block, B is the thickness of the eccentric block, and ρ is the density of the eccentric block.

[0103] Table 1 below is a parameter table of gradation of earth-rock dam materials, and rolling is performed based on this parameter table.

[0104] Table 1 Grading parameters of earth-rock dam materials

[0105]

[0106] like Fig. 9 As shown, when the number of roller pressing times exceeds 4, the compaction degree is close to 98%. As the number of rolling times increases, the compaction degree will approach 100%.

[0107] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
