Thus, the exemplary terms "at 8230; \8230; above" may include both orientations "at 8230; \8230; above" and "at 8230; \8230; below". The device may be otherwise variously positioned and the spatially relative descriptors used herein interpreted accordingly.
The application provides a slot milling machine control method. Referring to fig. 1 and 2, the slot milling machine includes a cutting device 1, a slag discharging device 3, and a power device 4. The cutting device 1 is rotatable for performing work. The slag discharging device 3 is used for discharging the slag generated by the operation of the cutting device 1. The power device 4 provides power for the cutting device 1 and the slag discharging device 3. The control method of the slot milling machine comprises the following steps:
s1, rotating a cutting device 1 at a set speed to perform operation;
s2, acquiring the real-time workload of the cutting device 1; and
and S3, adjusting the power provided by the power device 4 to the slag discharging device 3 according to the set load and the real-time working load of the cutting device 1.
Through the control method provided by the application, the working power of the slag discharging device 3 can be adaptively adjusted according to different operating environments, so that the cutting capability of the cutting device 1 is adaptive to the slag discharging capability of the slag discharging device, the utilization rate of the power provided by the power device 4 is improved, the operating efficiency under different operating environments is improved, and the energy loss is reduced.
Specifically, on the premise that the total power provided by the power device 4 is not changed, when the real-time workload of the cutting device 1 is large, the power of the slag discharging device 3 is reduced, and the power of the power device 4 is concentrated on the cutting device 1 to ensure the cutting efficiency; when cutting device 1's real-time work load is less, cutting device 1 is not very big to the demand of power, consequently shifts to the partly of the power that provides cutting device 1 for sediment device 3 that arranges, improves the efficiency of sediment device 3 discharge dregs, thereby reduces to arrange sediment efficiency and cutting efficiency and mismatch and lead to the dregs to pile up the risk that reduces the operating efficiency.
In order to pursue greater construction efficiency, in some embodiments, the cutting device 1 includes at least two milling cutters, and adjusting the power provided by the power device 4 to the slag discharge device 3 according to the set load and the real-time working load of the cutting device 1 includes: when the working loads of at least two milling cutters are smaller than the set load, the power provided by the power device 4 to the slag discharging device 3 is improved. In particular, at least two milling cutters may cooperate to improve cutting efficiency. When the working loads of at least two milling cutters are smaller than the set load, the hardness of the working environment at the moment is low, more dregs need to be discharged, the power requirement of the milling cutters is low, the power of the slag discharging device 3 needs to be increased at the moment, and the slag discharging efficiency is improved.
In some embodiments, adjusting the power provided by the power device 4 to the slag discharging device 3 according to the set load and the real-time working load of the cutting device 1 comprises: when the working load of at least one of the at least two milling cutters is greater than the set load, the power provided by the power device 4 to the slag discharging device 3 is reduced. When the working load of one milling cutter in at least two milling cutters is greater than the set load, the working environment hardness is higher, the amount of the slag soil required to be discharged is less, and the power requirement of the milling cutter is high, so that a part of the power of the slag discharging device 3 can be supplied to the milling cutter, and the cutting efficiency is improved.
In order to increase the efficiency of construction without increasing the overall dimensions of the slot milling machine, in some embodiments, still referring to fig. 1, the cutting device 1 comprises a first milling cutter 11 and a second milling cutter 12. The power unit 4 includes a first power unit 41 and a second power unit 42. The first power device 41 is disposed corresponding to the first milling cutter 11 and configured to provide power to the first milling cutter 11. The second power device 42 is disposed corresponding to the second milling cutter 12 and configured to provide power to the second milling cutter 12. The first power device 41 and the second power device 42 are also configured to jointly power the slag discharge device 3. The set load includes a first set value. The power provided by the power device 4 to the slag discharging device 3 is adjusted according to the set load and the real-time working load of the cutting device 1, and comprises the following steps: and when the working load of at least one milling cutter of the first milling cutter 11 and the second milling cutter 12 is smaller than a first set value, increasing the power provided by the power device corresponding to the at least one milling cutter to the slag discharging device 3. If the size of the power device 4 is directly increased in order to increase the power of the power device 4, the overall size of the slot milling machine is also increased, so that the slot milling machine is not beneficial to operation in a narrow space, and therefore, the problem that a single power device with a large size cannot be installed to operate in a narrow space can be effectively solved by adopting a double-power device to provide power for the first milling cutter 11, the second milling cutter 12 and the slag discharging device 3.
Further, in consideration of the complexity of the actual working environment, there may be a case where one side is less hard and the other side is more hard. For example, when the hardness of the working environment on the side of the first milling cutter 11 is low, and the real-time workload is less than the first set value, and the real-time workload of the second milling cutter 12 is not less than the first set value, since the power of the slag discharging device 3 is provided by the first power device 41 and the second power device 42, the power provided by the first power device 41 to the first milling cutter 11 is reduced, and the power provided to the slag discharging device 3 is increased, so that the working state of the second milling cutter 12 is not affected, the power distribution of the slot milling machine can be well coordinated, the working efficiency is guaranteed, and the energy loss is avoided.
In some embodiments, adjusting the power provided by the power device 4 to the slag discharging device 3 according to the set load and the real-time work load of the cutting device 1 further comprises: when the working load of at least one of the first milling cutter 11 and the second milling cutter 12 is larger than a first set value, the power provided by the power device corresponding to the at least one milling cutter to the slag discharging device 3 is reduced. For example, when the real-time workload of the first milling cutter 11 is greater than the first set value and the real-time workload of the second milling cutter 11 is not greater than the first set value, it indicates that the hardness of the working environment on the side of the first milling cutter 11 is greater, and at this time, the power provided by the first power device 41 to the first milling cutter 11 is increased and the power provided by the first power device to the slag discharge device 3 is reduced, so that the working state of the second milling cutter 12 is not affected, and the power distribution condition of the slot milling machine can be well coordinated, thereby ensuring the working efficiency and avoiding the energy loss. When the real-time workload of the first milling cutter 11 and the real-time workload of the second milling cutter 12 are both greater than the first set value, it indicates that the hardness of the working environments on both sides is relatively high, the power demand of the slag discharge device 3 is relatively low, and the power demand of the two milling cutters is relatively high, so that the power supplied to the slag discharge device 3 by the first power device 41 and the second power device 42 is reduced, and the power distribution of the slot milling machine is more reasonable.
Furthermore, when the real-time workload of the first milling cutter 11 is greater than the first set value and the real-time workload of the second milling cutter 12 is less than the first set value, the power provided by the second power device 42 to the second milling cutter 12 is reduced and the power provided to the slag discharge device 3 is increased on the basis of the above adjustment (i.e., the power provided by the first power device 41 to the first milling cutter 11 is increased and the power provided by the first power device to the slag discharge device 3 is reduced), so that the working power of each milling cutter can be matched with the respective environmental hardness, the rationality of power distribution is further improved on the basis of ensuring the normal operation of the slag discharge device 3, and the energy loss is reduced.
In order to cope with the extreme working environment and guarantee the operation safety of the slot milling machine, referring to fig. 3, in some embodiments, the control method of the slot milling machine further comprises: the rotation speed of the cutting device 1 is adjusted according to the safety limit values and the real-time workload of the cutting device 1. The safety limit value is larger than the set load. The safety limit value is used for protecting the working safety of the cutting device 1, preventing the structure from being damaged due to overlarge working load of the cutting device 1 and reducing the service life of the slot milling machine.
In some embodiments, adjusting the rotation speed of the cutting device 1 according to the safety limit values and the real-time workload of the cutting device 1 comprises: when the real-time workload of the cutting device 1 is greater than the safety limit value, the rotational speed of the cutting device 1 is reduced. In particular, when the hardness of the working environment is greater than a certain degree, the load of the milling cutter may also be excessive, which may cause damage to the milling cutter. In this case, the rotation speed of the milling cutter is directly reduced to ensure the safety of the equipment.
In order to further optimize the flexibility and rationality of the power distribution of the slot milling machine in working environments of different hardness, in some embodiments the set load further comprises a second set point. The second set value is greater than the first set value and less than the safety limit value. The power provided by the power device 4 to the slag discharging device 3 is adjusted according to the set load and the real-time working load of the cutting device 1, and the power comprises the following steps: when the work load of one of the first milling cutter 11 and the second milling cutter 12 is greater than the second set value, the power device corresponding to the one milling cutter is stopped from supplying power to the slag discharge device 3. Specifically, the magnitude of the second setting value satisfies: the first set value is larger than the second set value and is smaller than the safety limit value. When the real-time workload of the first milling cutter 11 is greater than the second set value and the real-time workload of the second milling cutter 12 is not greater than the second set value, it indicates that the hardness of the working environment on the side of the first milling cutter 11 is great and the hardness of the working environment on the side of the second milling cutter 12 is great or small at this time, and in order to ensure the normal operation of the first milling cutter 11, the first power device 41 completely provides power to the first milling cutter 11 at this time to ensure the operation of the first milling cutter 11. The power of the slag discharging device 3 is completely provided by the second power device 42.
In some embodiments, referring to fig. 1, the power plant 4 may be a hydraulic pump. For example, the first power unit 41 and the second power unit 42 may be a first hydraulic pump and a second hydraulic pump. The first hydraulic pump is connected with the first milling cutter 11 via a first hydraulic system a-1. The second hydraulic pump is connected with the second milling cutter 12 through a second hydraulic system A-2. The first hydraulic pump and the second hydraulic pump are connected with the slag discharging device 3 through a third hydraulic system A-3.
In some embodiments, the slag extraction device may be configured to be powered by one of two power devices, e.g., a first power device to power the first mill and the slag extraction device, and a second power device to power only the second mill. Under the condition, when the real-time working load of the first milling cutter is larger, the power provided by the first power device to the slag discharging device is reduced, and the power provided by the first power device to the first milling cutter is improved; when the real-time working load of the first milling cutter is smaller, the power provided by the first power device to the slag discharging device is improved, and the power provided by the first power device to the first milling cutter is reduced. Of course, the second power device can also be used for improving the power of the second milling cutter and the slag discharging device, and the first power device only improves the power of the first milling cutter.
In some embodiments, the power plant may also be an electric motor or a diesel engine.
The application also provides a slot milling machine which comprises a cutting device 1, a slag discharging device 3, a power device 4 and a controller. The cutting device 1 is configured to be rotatable to perform work. The slag discharge device 3 is configured to discharge the slag generated by the operation of the cutting device 1 to perform the operation in cooperation with the cutting device 1. The power device 4 provides power for the cutting device 1 and the slag discharging device 3 to perform work. The controller is in signal connection with the power means 4 and is configured to perform the method of controlling the slot milling machine as described above. Specifically, the set speed, the set load, and the safety limit values described above are stored in the controller. Through the slot milling machine, in the actual operation process, when the hardness of the operation environment is continuously changed, the controller can adaptively adjust the power states of the cutting device 1 and the slag discharging device 3, so that the operation applicability is improved, and the energy loss is reduced.
In some embodiments, the slot milling machine further comprises a load monitoring device 2, the load monitoring device 2 is in signal connection with the controller, and the load monitoring device 2 is configured to monitor the work load of the cutting device 1 in real time. The load monitoring device 2 may be a pressure gauge.
It should be understood that the workload described above may specifically be pressure, power, or other reference. And the first set value, the second set value and the safety limit value can be adaptively adjusted according to the model of the slot milling machine, the size of the milling cutter and a working scene so as to meet the requirements.

Firstly, the controller inputs the rotation speeds of the two milling cutters, the load monitoring device 2 acquires the real-time loads of the two milling cutters, and one of the two milling cutters (for example, the second milling cutter 12) is used as a first judgment target, and the other is used as a second judgment target, so that the working load condition of the second milling cutter 12 is firstly judged, and the method can be divided into three types:
if the work load of the second milling cutter 12 is smaller than the first set value, the work load condition of the first milling cutter 11 is judged, and at this time, three conditions can be divided: a. if the working load of the first milling cutter 11 is smaller than the first set value, the controller increases the power provided by the first power device 41 and the second power device 42 to the slag discharging device 3; b. if the work load of the first milling cutter 11 is between the first set value and the safety limit value, the power output of the first power device 41 to the slag discharge device 3 is reduced, and the power output of the second power device 42 to the slag discharge device 3 is improved; c. if the work load of the first milling cutter 11 is greater than the safety limit, the rotational speed of the first milling cutter 11 is reduced.
If the work load of the second milling cutter 12 is between the first set value and the safety limit value, the work load condition of the first milling cutter 11 is judged, and at this time, three conditions can be divided: d. when the working load of the first milling cutter 11 is smaller than the first set value, the controller increases the power output of the first power device 41 to the slag discharging device 3 and reduces the power of the second power device 42 to the slag discharging device 3; e. when the work load of the first milling cutter 11 is between the first set value and the safety limit value, the power output of the first power device 41 and the second power device 42 to the slag discharging device 3 is reduced; f. if the work load of the first milling cutter 11 is greater than the safety limit, the rotational speed of the first milling cutter 11 is reduced.
