Detailed Description
In order to further describe the technical means and effects adopted by the invention to achieve the preset aim, the following detailed description is given below of the specific implementation, structure, characteristics and effects of the self-driven adjusting device for the TBM disc cutter according to the invention with reference to the attached drawings and the preferred embodiment.
Please refer to fig. 1, which is a schematic structural diagram of a self-driving adjusting device of a TBM disc cutter according to the present invention, the device includes a cutter 1, a magnetorheological clutch and a motor 7, the cutter 1 is mounted on a cutter holder 2, and a speed sensor 16 is disposed on the cutter shaft of the cutter 1 for detecting whether the cutter 1 rotates.
The magnetorheological clutch comprises a magnetorheological clutch housing 15, wherein the magnetorheological clutch housing 15 is filled with magnetorheological fluid 3, an exciting coil 11, a driving shaft 10 and a driven shaft 12 are arranged in the magnetorheological clutch housing 15, and an electric brush 4 and a collecting ring 5 are arranged outside the magnetorheological clutch housing 15. Preferably, the opposite ends of the driving shaft 10 and the driven shaft 12 are fixed with driving discs to increase the driving force therebetween, but not limited thereto.
A second bevel gear 14 is arranged at one end of the cutter shaft of the hob 1, and the second bevel gear 14 is meshed with a first bevel gear 13 arranged on the driven shaft 12.
The motor 7 is fixed on a motor support 8, the motor support 8 is fixed on a connecting plate 9, and the connecting plate 9 is fixedly connected with the tool apron 2. The motor 7 is connected with a driven shaft 10 through a coupling 6.
The speed sensor 16 is electrically coupled to the controller of the magnetorheological clutch, and the speed sensor 16 detects the rotational speed of the arbor and transmits the detected information to the controller of the magnetorheological clutch. When the speed sensor 16 detects that the cutter shaft speed is not zero, the controller of the magnetorheological clutch controls the clutch exciting coil 11 to be powered off, and the magnetorheological clutch stops working. When the speed sensor 16 detects that the cutter shaft speed is zero, the controller of the magneto-rheological clutch controls the clutch exciting coil 11 to be electrified, the magneto-rheological clutch starts to work, the cutter shaft is driven to rotate, and therefore the hob 1 is driven to rotate.
When the exciting coil 11 is electrified to generate a magnetic field, the magnetorheological fluid clutch is combined, and the power of the motor 7 is transmitted to the second bevel gear 14 through the first bevel gear 13, so that the rolling of the hob 1 is realized; when the magnetic field is removed by power failure, the magnetorheological fluid clutch is disconnected, and the power of the motor 7 cannot be transmitted to the second bevel gear.
According to the self-driving adjusting device for the TBM disc cutter, when a TBM cutter head is driven, whether the cutter head rolls during driving can be detected through the speed sensor 16 arranged on the cutter shaft of the cutter head 1, and if the cutter head does not roll, the motor transmits power to the cutter head 1 through the coupler, the magneto-rheological clutch and the bevel gear pair. When the hob rolls normally in tunneling, the magneto-rheological clutch is disconnected, and the motor power is disconnected. The magnetorheological fluid clutch adopted by the structure has high response speed and can drive the hob to roll in time.
The present invention is not limited to the above-mentioned embodiments, but is not limited to the above-mentioned embodiments, and any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical matters of the present invention can be made by those skilled in the art without departing from the scope of the present invention.
