Description

Energy-saving control system and control method of vibratory roller and vibratory roller
Technical Field
The invention relates to the technical field of vibratory rollers, in particular to an energy-saving control system of a vibratory roller, a control method of the energy-saving control system of the vibratory roller and the vibratory roller.
Background
The conventional vibratory roller generally comprises a driving system and a vibration system, wherein the driving system enables the front and rear of the roller to carry out static rolling on the road surface so as to realize compaction of the road surface; the vibration system enables the vibration wheel to vibrate, and vibration compaction is achieved on the road surface. The driving compaction and the vibration compaction are carried out simultaneously, and the road surface can be ground by driving alone, and the system is described by taking a single steel wheel vibratory roller as an example. The transmission route of the running system is an engine, a running hydraulic pump, a running hydraulic motor, a rear axle and tires. Among them, there are two ways to realize the change of the running speed: when the engine speed is changed and the displacement of the running hydraulic pump and the displacement of the running hydraulic motor are unchanged, the running speed is related to the engine; the other is that the engine speed is unchanged, the displacement of the running hydraulic motor is unchanged, the displacement of the running hydraulic pump is controlled, and the change of the running speed can be realized.
The transmission route of the vibration system is an engine, a vibration hydraulic pump, a vibration hydraulic motor and an eccentric structure inside the vibration wheel. The engine rotates to drive the vibration hydraulic pump to rotate, the vibration hydraulic motor rotates through the hydraulic rubber tube, and the vibration hydraulic motor drives the eccentric structure of the vibration wheel to rotate to generate exciting force. The vibration wheel needs to keep stable frequency when vibrating, and the ground compaction can be smooth and consistent.
Since the running system and the vibration system share one engine, the engine must maintain a stable rotational speed in order to maintain a stable vibration frequency.
When the running system and the vibration system work together, for example, the vibration roller compacts the road surface by utilizing the steel wheel and the vibration excitation system inside the steel wheel in the running acceleration process, the vibration system can be started immediately, and at the moment, the running power and the vibration power are overlapped, so that the running acceleration of the vibration roller and the rapid starting vibration of the vibration excitation system are met, the power of a generally prepared engine is higher, and meanwhile, the stability of the frequency of vibration (namely, the vibration excitation system inside the steel wheel) is met, and the speed of the engine is in the maximum state, the load rate is low and the oil consumption is high in the actual work of the vibration roller.
At present, common practice in the industry is as follows: the engine is at the maximum rotation speed, and the change of the running speed of the road roller is realized by controlling the change of the displacement of the running pump. When vibration is needed, the vibration button is pressed down, the vibration wheel realizes stable vibration frequency (because the rotation speed of the engine is unchanged) to compact the road surface, but the engine is always at the maximum rotation speed, so that energy is wasted, and noise is high.

The fuel consumption is lower when the load rate of the engine is stabilized at 60% -80%, and the energy-saving effect is better obtained through the following tests:

The vibratory roller provided by the invention has all beneficial technical effects of the energy-saving control system of the vibratory roller because the energy-saving control system of the vibratory roller comprises any technical scheme, and the energy-saving control system of the vibratory roller is not described in detail herein.
In the specific embodiment, as shown in fig. 3 and 4, the vibratory roller comprises an electric control engine 1, a speed increasing box 18, an electric control handle 11, a controller 10, a running wheel 4, a vibration wheel 7, a working button 12, an electric control running pump 2 connected with the running wheel 4, a running motor 3, a vibration pump 5 connected with the vibration wheel 7, a vibration motor 6, a running pump displacement sensor 15 connected with the electric control running pump 2 and used for detecting the displacement change rate of the electric control running pump 2, a vibration pump displacement sensor 16 connected with the vibration pump 5 and used for detecting the displacement change rate of the vibration pump 5, a running speed sensor 8 connected with the running wheel 4 and used for detecting the speed change rate of the running wheel 4, an engine detection unit 13 connected with the vibration wheel 7 and used for detecting the work load rate of the electric control engine 1, and an engine detection unit 13 connected with the electric control running wheel 7. Further comprising a vibration pump displacement sensor 16 for detecting the displacement of the vibration pump 5, the controller 10 adjusts the operating state of the vibration pump 5 according to the signal of the vibration pump displacement sensor 16.
The electric control handle 11 is connected with the electric control engine 1 and the electric control running pump 2, the driving handle and the vibratory roller walk, an operator controls the electric control handle 11 to push forwards, namely, the stroke is increased, the controller 10 controls the electric control engine 1 to increase the accelerator, controls the electric control running pump 2 to increase the displacement, and increases the speed of the running wheels 4, so that the speed change control of the running wheels 4 is realized.
Specifically, under the simple driving condition of the vibratory roller, in the starting stage, an operator controls the electric control operating handle 11 to a certain position to enable the vibratory roller to drive, and the controller 10 can automatically adjust the rotating speed of the electric control engine 1 and the displacement of the electric control driving pump 2 according to the position of the electric control operating handle 11, so that the problems that in the related art, the operating handle can only adjust the displacement of the driving pump, the rotating speed of the engine cannot be adjusted, and the rotating speed of the engine is always at the maximum rotating speed, and energy is wasted are avoided.
In the starting stabilization stage, after the vibratory roller is stabilized in running, the controller 10 (energy-saving controller) monitors the data of the running speed sensor 8, after judging that the running speed is stabilized, the working load rate of the electric control engine 1 is detected by the electric control engine detecting unit 13, the rotating speed of the electric control engine is adjusted according to the working load rate of the electric control engine 1 to enable the working load rate to reach a preset load rate (such as 80 percent of the load rate), the initial rotating speed is the rotating speed corresponding to the 80 percent of the load rate of the electric control engine 1, the electric control engine 1 works at the initial rotating speed to reach the preset load rate due to the fact that the initial rotating speed is smaller than the maximum rotating speed of the electric control engine 1, and the oil consumption of the electric control engine 1 can be greatly reduced due to the fact that the electric control engine 1 works at the preset load rate, so as to achieve the purpose of energy saving of the electric control engine 1, since the running speed of the running wheel 4 is changed due to the change of the rotating speed of the electric control engine 1 in the process of adjusting the electric control engine 1 to the preset load rate, the displacement of the electric control running pump 2, the displacement of the running motor 3 or the working state of the speed increasing box 18 is correspondingly adjusted based on the signal of the running speed sensor 8 by detecting the running speed change rate of the running wheel 4, closed loop control is formed, so that the electric control engine 1 and the electric control running pump 2, the running motor 3 or the speed increasing box 18 work together to meet the power requirement of the whole vibratory roller, and when the rotating speed of the electric control engine 1 is changed rapidly to influence the change of the speed of the running wheel 4, the change of the rotating speed of the electric control engine 1 is not influenced by the speed of the running wheel 4 by adjusting the displacement of the electric control running pump 2, the displacement of the running motor 3 or the working state of the speed increasing box 18, further, the speed stability of the running wheel 4 is ensured not to be suddenly changed, the reliability of the product is improved, and the satisfaction degree of the use of a user is improved.
Since the displacement change of the electric control running pump 2 is related to the load rate of the electric control engine 1 in the running stage of the vibratory roller, the displacement change rate of the electric control running pump 2 is detected by the electric control running pump displacement sensor, when the displacement change is large, the electric control engine 1 is indicated to have a high load rate, the controller 10 automatically adjusts the displacement of the electric control running pump 2, the displacement change rate of the electric control running pump 2 is reduced, and then the load rate of the electric control engine 1 is reduced. The load rate of the electric control engine 1 is still kept within the preset load rate range, so that the electric control engine 1 is ensured to continuously keep running at the initial rotating speed which is smaller than the maximum rotating speed, the oil consumption is reduced, the energy is saved, and the noise of the electric control engine 1 is reduced.
In the vibration state of the vibratory roller, in the vibration starting stage, when the working button 12 is pressed in the driving process of the roller, the vibration wheel 7 of the roller needs to start vibrating immediately (accelerating from zero to stable frequency), the required power of the electric control engine 1 is larger, and the rotating speed of the electric control engine 1 needs to accelerate to the highest rotating speed immediately to provide the maximum power. Since the rapid rise of the rotation speed of the electric control engine 1 will affect the change of the running speed, the running speed sensor 8 detects the speed change rate of the running wheels 4, and when the rapid rise of the rotation speed of the electric control engine 1 and the change rate are large, the controller 10 immediately adjusts the displacement of the electric control running pump 2 according to the signal of the running speed sensor 8 to form closed loop control, so that the change of the rotation speed of the electric control engine 1 does not affect the running speed.
In the vibration stabilization phase, i.e. after the vibratory roller has stabilized in vibration, the vibratory roller does not need maximum power. At this time, the controller 10 monitors the data of the vibration sensor 9 (such as a speed sensor), and after judging that the vibration speed or frequency is stable, the controller 10 automatically reduces the rotation speed of the electronically controlled engine 1 to the initial engine rotation speed state according to the signal of the vibration sensor 9. At this time, the controller 10 immediately changes the displacement control signal of the electric control running pump 2 or the running motor 3 or the speed increasing box 18 due to the change (decrease) of the rotation speed of the electric control engine 1, so as to form closed loop control, and the change of the rotation speed of the electric control engine 1 does not affect the running speed.
In the vibration stopping stage, that is, when the working button 12 is pressed again, the vibration wheel 7 stops vibrating, the vibration road roller is unloaded in instantaneous time, and the electric control engine 1 is accelerated instantaneously. At this time, the travel speed sensor 8 detects the speed change rate of the travel wheels 4, and the controller 10 immediately adjusts the displacement of the electric control travel pump 2 according to the signal of the travel speed sensor 8 due to the large speed change rate, thereby achieving the stabilization of the travel speed.
According to the method, the rotating speed of the electric control engine 1 is flexibly controlled through the controller 10 according to the position of the electric control handle 11, the displacement of the electric control running pump, the displacement of the running motor or the working state of the speed increasing box are flexibly adjusted, the rotating speed of the electric control engine 1 can be effectively reduced, the energy consumption and the noise of the electric control engine 1 are further reduced, the energy saving effect of the vibratory roller in the whole working period is obvious, more than 20% of energy saving can be achieved, the use cost is further reduced, and meanwhile, the working efficiency (running speed and vibration frequency) of the vibratory roller can be guaranteed through flexibly adjusting the displacement of the electric control engine 1 and the electric control running pump 2, the displacement of the running motor 3 or the working state of the speed increasing box 18, the market competitiveness of products is greatly improved, and the satisfaction degree of use of users is improved.
