When the existing double-wheel slot milling machine carries out slot-cutting operation, the buoyancy of a double-wheel milling cutter frame is generally not considered, which causes inaccuracy in calculating the feeding force and further influences the value of the rotating speed of the wheel milling on the double-wheel milling cutter frame.

The main roll depth measuring unit 20 is connected to the main roll 11 for measuring the grooving depth of the tool holder 10.
The tension measuring unit 30 is connected to the main roll 11 for measuring the main roll tension provided by the main roll 11.
The controller 40 is connected to both the main roll depth measuring unit 20 and the tension measuring unit 30, and is configured to collect the grooving depth measured by the main roll depth measuring unit 20 and the main roll tension provided by the main roll 11 measured by the tension measuring unit 30, and determine the buoyancy of the tool rest 10 based on the grooving depth and the main roll tension.
The controller 40 is connected with the wheel mill 101, and is further configured to determine a feed force signal based on the buoyancy, and send the feed force signal to the wheel mill 101, so that the wheel mill 101 performs a grooving operation based on a wheel mill rotation speed corresponding to the feed force signal.
In the embodiment of the present application, the main roll 11 of the tool holder 10 is used for providing a pulling force for moving the tool holder 10 in a vertical direction, a release distance of the main roll 11 corresponds to a displacement distance of the tool holder 10, that is, the main roll depth measurement unit 20 may be mounted on the main roll 11, a grooving depth of the tool holder 10 can be indirectly determined by the release distance of the main roll 11, and the main roll depth measurement unit 20 is physically connected with the main roll 11.
The main roll depth measurement unit 20 is a collection unit, and can send the collected corresponding distance analog signal to the controller 40 for processing, so that the controller 40 can convert the distance analog signal sent by the main roll depth measurement unit 20 into a corresponding distance digital signal to obtain the grooving depth of the tool rest 10, and the main roll depth measurement unit 20 is in communication connection with the controller 40.
The tension measuring unit 30, as a collecting unit, can send the collected corresponding tension analog signal to the controller 40 for processing, so that the controller 40 can convert the tension analog signal sent by the tension measuring unit 30 into a corresponding tension digital signal to obtain the tension provided by the main roll 11 for the movement of the tool holder 10, and the tension measuring unit 30 and the main roll 11 are also physically connected.
In the embodiment of the present application, the wheel mill 101 of the tool rest 10 is used for performing excavation operation, that is, when the tool rest 10 reaches a preset position, the controller 40 controls the wheel mill 101 to excavate according to a preset rotation speed, the preset rotation speed may be obtained from a corresponding relationship between a feed force signal and a wheel mill rotation speed, which are pre-stored in the controller 40, and the feed force signal may be determined by a buoyancy determined by a grooving depth and a main roll tension, it should be understood that, in the embodiment of the present application, the reason for the existence of the buoyancy is that the double-wheel slot milling machine continuously fills slurry into the groove during the slot-milling process, so that crushed stones and the like generated by the slot-milling can be conveniently cleaned together with the slurry, which is caused by a working environment of the double-wheel slot milling machine.
Through the arrangement, the problem that the buoyancy is not considered when the feeding force signal is determined in the conventional grooving operation can be solved.
On the basis of the foregoing, the grooving depth includes a current grooving depth and a historical grooving depth. The controller 40 is used for collecting the current grooving depth and the historical grooving depth of the tool holder 10 measured by the main roll depth measuring unit 20.
The main roll depth measurement unit 20 may send the measured groove depth corresponding to the position of the tool holder 10 to the controller 40 when the previous operation is completed, and the controller 40 may use the groove depth as the historical groove depth, and it should be understood that each time the operation is completed, the groove bottom of the groove being excavated by the tool holder 10 is contacted, that is, the historical groove depth can represent the groove bottom position of the groove. And the current grooving depth is the real-time position of the tool holder 10 acquired by the main roll depth measuring unit 20. With the above arrangement, the controller 40 can determine the state of the tool holder 10 based on the current real-time position of the tool holder 10 and the groove bottom position.
In addition, the controller 40 is further configured to collect a first main roll tension measured by the tension measuring unit 30 when a difference between the current grooving depth and the historical grooving depth is a preset difference, and determine the buoyancy based on the difference between the first main roll tension and the gravity of the tool holder 10.
Referring to fig. 3, in addition to the buoyancy, the tool rest 10 further includes other resistance generated by the contact between the tool rest 10 and the groove wall during the operation, when the difference between the current grooving depth measured by the main roll depth measuring unit 20 and the historical grooving depth collected by the controller 40 is a preset difference, the tool rest 10 may be considered to have completely entered the groove, that is, completely entered the mud pit in the groove, in this state, the controller 40 may collect the first main roll tension measured by the tension measuring unit 30, and then subtract the gravity of the tool rest 10 obtained in advance from the first main roll tension, so that the sum of the buoyancy and the other resistance may be obtained, and for convenience of calculation, the sum of the buoyancy and the other resistance may be treated as the contact force. It is to be noted that the predetermined difference can be set to be smaller, i.e. the tool holder 10 is closer to the groove bottom when the buoyancy of the tool holder 10 is detected, so that the contact force detected at this point can be used as a reference contact force after the subsequent contact of the tool holder 10 with the groove bottom.
On the basis of the above, the controller 40 is further configured to collect the second main roll tension measured by the tension measuring unit 30 when the current grooving depth and the historical grooving depth are equal, and determine the feed force signal based on the difference between the gravity of the tool holder 10 and the second main roll tension and the buoyancy.
Referring to fig. 4 in conjunction, after the buoyancy of the tool holder 10 is captured, the tool holder 10 continues to move downward, and when the current grooving depth and the historical grooving depth are equal, the tool holder 10 may be considered to have contacted the groove bottom (i.e., the mill 101 contacts the groove bottom), and as before, the sum of the buoyancy and other resistance of the tool holder 10 and the sum of the buoyancy and other resistance when the contact force is captured may be considered equal. The controller 40 can collect the second main roll tension measured by the tension measuring unit 30, and can use the gravity of the tool holder 10 to subtract the second main roll tension and the contact force to determine the required feeding force, and the controller 40 can receive the analog feeding force signal and process the analog feeding force signal to obtain a feeding force signal (i.e., a digital feeding force signal). After the feed force signal is determined, the rotational speed of the cutterhead 101 can be determined from the feed force signal and the cutterhead rotational speed, which are pre-stored in the controller 40, so that the cutterhead 101 performs a grooving operation at the cutterhead rotational speed. Through the steps, the influence of the buoyancy on the feeding force can be automatically removed without manual operation of an operator, so that the intelligent control of the double-wheel slot milling machine is realized, and it is worth explaining that the real feeding force can be accurately obtained, and further the wheel milling rotating speed of the wheel milling machine 101 can be provided, so that the equipment can be operated at higher efficiency, and the service life of the equipment is prolonged.
Based on this, the controller 40 further stores the corresponding relation between the feeding force signal and the rotating speed of the mud pump, and the double-wheel milling cutter frame 1 further comprises the mud pump which is connected with the controller 40. The controller 40 is used for sending a feeding force signal to the mud pump so as to enable the mud pump to carry out mud discharging operation based on the rotating speed of the mud pump corresponding to the feeding force signal.
In an environment of operation of the double-wheel slot milling machine, slurry needs to be continuously filled into the groove, the determination of the feeding force also influences the filling of the slurry, and specifically, after the feeding force signal is determined, the controller 40 can control the rotating speed of a slurry pump of the slurry pump based on the corresponding relationship between the feeding force signal and the rotating speed of the slurry pump, namely, control the slurry output of the slurry pump.
In addition to the above correspondence, the controller 40 further stores the correspondence between the feed force signal and the rotation speed of the slurry suction pump, and the double-wheel milling cutter holder 1 further includes the slurry suction pump connected to the controller 40. The controller 40 is configured to send a feeding force signal to the suction pump so that the suction pump performs a suction operation based on a rotation speed of the suction pump corresponding to the feeding force signal.
Accordingly, when the double-disc slot milling machine is operated, not only the slurry is filled by the slurry pump, but also the crushed stones and the like generated by the slot milling operation are mixed into the slurry and then cleaned. A suction pump may be provided to allow the user to suck out the slurry mixed with the crushed stones so that the new slurry has sufficient space to be poured in. After the controller 40 receives and determines the feeding force signal, the suction pump can be controlled to suck out the slurry in the groove based on the corresponding relation between the feeding force signal and the rotation speed of the suction pump, which is stored in the controller 40 in advance. Through the steps, after the accurate feeding force is determined, the rotation speed of the wheel milling machine, the rotation speed of a slurry pump and the rotation speed of a slurry suction pump can be correspondingly and accurately determined, so that the whole double-wheel slot milling machine has a complete and accurate operation cycle when operating, and the operation efficiency of the double-wheel slot milling machine is improved.

The tension measuring unit 30 is configured to collect pressure at an oil inlet of the main hoisting motor and pressure at an oil outlet of the main hoisting motor, and calculate a main winding tension provided by the main winding based on a pressure difference between the pressure at the oil inlet and the pressure at the oil outlet.
Besides the mode of using the tension sensor to obtain the main winding tension, the pressure of an oil inlet of the main winding motor and the pressure of an oil outlet of the main winding motor can be respectively collected.
