[0047] Exemplarily, the first linear drive member 26 is an electric cylinder.

[0048] When the folding rudder 6 needs to be folded, the first linear drive member 26 drives the slide 24 to move along the first guide rail 25, thereby connecting the torsion plug 231 to the folding rudder 6, and starting the servo motor 21 to fold the folding rudder 6 under the rotation of the connecting shaft 23.

[0050] like Figures 3 and 4As shown, the torque load application unit 3 includes a lifting platform assembly 31, a second guide rail 32, a longitudinal plate 35, a lifting drive 36, and a second linear drive 37. The lifting platform assembly 31 includes a lifting platform 311, a linear slide 312, and a lifting slide 315. The linear slide 312 and the lifting slide 315 are both connected to the lifting platform 311 and are arranged vertically.

The lifting drive 36 is used to drive the lifting platform 311 to slide along the lifting slide 351, and the second linear drive 37 is used to drive the lifting platform 311 to slide along the second guide rail 32.

[0051] Exemplarily, the lifting drive member 36 and the second linear drive member 37 are both electric cylinders.

[0052] Preferably, the lifting platform assembly 31 further includes a third thrust member 313 , which is used to prevent the lifting platform assembly 31 from excessively sliding along the second guide rail 32 and causing collision or damage to components.

[0053] like Figure 5 As shown, the torque load application unit 3 also includes an elastic element 33 and a bearing stopper 34. The elastic element 33 is connected to the bearing stopper 34. A connecting pin is provided on the bearing stopper 34. The bearing stopper 34 can be connected to the connecting shaft 23 or the folding rudder 6 via the connecting pin. The end of the elastic element 33 connected to the bearing stopper 34 can rotate synchronously with the bearing stopper 34. The bearing stopper 34 is detachably connected to the lifting platform 311 via the bearing stopper. The torque applied to the folding rudder can be changed by adjusting the size, number, and combination of the elastic elements 33. The lifting platform assembly 31 also includes a fixed stopper 314, which is detachably connected to the lifting platform 311 and fixedly connected to the elastic element 33. The fixed stopper 314 cooperates with the bearing stopper 34 to connect the elastic element 33 and cause the elastic element 33 to twist as the bearing stopper 34 rotates. An adjustment groove 3111 is also provided on the lifting platform 311, and a plurality of mounting holes are provided in the adjustment groove 3111. The shape of the adjustment groove 3111 cooperates with the fixed limit seat 314 and the bearing limit seat 34. The fixed limit seat 314 or the bearing limit seat 34 can move along the adjustment groove 3111 and be fixed in the adjustment groove 3111 by bolts and the mounting holes.

[0054] When a load needs to be applied to the foldable rudder 6, the foldable rudder 6 is folded by the rotating unit 2, and then the rotating unit 2 is moved along the first guide rail 25 to one side of the lifting platform 311. The lifting drive 36 is used to raise the lifting platform 311 until the axes of the bearing stopper 34 and the fixed stopper 314 are collinear with the axis of the connecting shaft 23. The combination, size, and number of elastic elements 33 are determined based on theoretical calculation results. The position of the bearing stopper 34 is adjusted along the adjustment slot 3111 according to the length, and the bearing stopper 34 is fixed in the adjustment slot 3111 with bolts. The position of the slide 24 is adjusted so that the bearing stopper 34 is inserted into and connected to the connecting shaft 23. The fixed stopper 314 is fixed to the lifting platform 311 with bolts, so that one end of the elastic element 33 is connected to the bearing stopper 34 and the other end is connected to the fixed stopper 314. The servo motor 21 is started, so that the end of the elastic element 33 connected to the bearing limit seat 34 rotates along the connecting shaft 23, and the end connected to the fixed limit seat 314 remains fixed, so that the elastic element 33 is twisted. The angle of rotation of the connecting shaft 23 is the same as the angle of rotation when the folding rudder 6 is folded. The torque generated by the twisting of the elastic element 33 is measured by the torque sensor 221, so as to detect the load size applied by the elastic element 33 during the unfolding of the folding rudder 6. The number, size and other parameters of the elastic element 33 are adjusted according to the output load size result, so that the torque generated by the twisting of the elastic element 33 reaches When the load reaches a predetermined level and the elastic element 33 is reset, the positions of the bearing limit seat 34 and the fixed limit seat 314 are adjusted, and the fixed limit seat 314 is fixed in the adjustment groove 3111. The bearing limit seat 34 is inserted into the folding rudder 6, and the detent is withdrawn to complete the deployment of the folding rudder 6. During the deployment process, the bearing limit seat 34 rotates as the folding rudder 6 is deployed, driving the elastic element 33 to twist, that is, the torque generated by the twisting of the elastic element 33 is applied to the folding rudder 6 through the bearing limit seat 34, thereby simulating the reverse load opposite to the deployment direction that the folding rudder 6 is subjected to during the deployment process.

[0055] For example, the elastic element 33 is an elastic metal sheet. By adjusting parameters such as the number and size of the elastic metal sheet, the magnitude of the load on the folding rudder 6 can be adjusted.

[0056] For example, the elastic element 33 is an elastic rod, and the magnitude of the load on the folding rudder 6 can be adjusted by adjusting parameters such as the number and size of the elastic rod.

[0057] like Figure 6As shown, the fixing unit 4 is symmetrically arranged on the machine tool frame 1, and the fixing unit 4 includes a pressure claw 41, a transmission rod 42, a third linear drive member 43 and a rotating rod 44.

When it is necessary to rotate the pressure claw 41 to fix the folding rudder 6, the transmission rod 42 is moved by the extension and contraction of the third linear drive member 43, and then the pressure claw 41 is driven to rotate. The rotating rod 44 rotates with the extension and contraction of the third linear drive member 43, thereby preventing the pressure claw 41 from being unable to rotate due to the length limit of the transmission rod 42.

[0058] Exemplarily, the third linear drive member 43 is an electric cylinder.

[0059] like Figure 7 As shown, the time monitoring unit 5 includes an adjustment rail 51, a first fixing member 52, a monitoring platform 53, and a signal transceiver 54. The adjustment rail 51 is connected to the machine tool frame 1. There are multiple monitoring platforms 53, which are connected to the adjustment rail 51 and can move along the adjustment rail 51. The position of the monitoring platform 53 is fixed by the first fixing member 52.

[0060] Illustratively, the first fixing member 52 is a fixing bolt.

[0061] Exemplarily, the first fixing member 52 is a fixing pin.

[0062] The signal transceiver 54 is set on the monitoring platform 53. By adjusting the position of the monitoring platform 53 along the adjustment guide rail 51, the signal transceiver 54 can monitor the position of the rudder wings in the unfolded state and the position of the rudder wings in the folded state of the folding rudder 6, thereby recording the time taken for the folding rudder 6 to unfold to the position of the signal transceiver 54.

[0063] Preferably, the time monitoring unit 5 further includes a second fixing member 55 , the signal transceiver 54 is connected to the monitoring platform 53 via a slider and a slide rail, and the position of the signal transceiver 54 is fixed by the second fixing member 55 .

[0064] Illustratively, the second fixing member 55 is a fixing bolt or a fixing pin.

[0065] Preferably, the time detection device for the folding rudder further comprises a PLC control panel, which is disposed in the machine tool frame 1 and is electrically connected to the rotating unit 2 , the torque load applying unit 3 and the fixing unit 4 .

[0066] Exemplarily, the PLC control panel is electrically connected to the first linear drive 26, the servo motor 21, the lifting drive 36, the second linear drive 37 and the third linear drive 43, and the first linear drive 26, the servo motor 21, the lifting drive 36, the second linear drive 37 and the third linear drive 43 can be controlled through the PLC control panel.

[0067] For example, the model of the PLC control panel is SIMATIC S7-1500.

[0068] Example 2

[0069] A specific embodiment of the present utility model discloses a time detection device for a folding rudder, such as Figure 8 As shown, the difference from Example 1 is that a first connecting lock 341 is further provided on the bearing limit seat 34, and the first connecting lock 341 is connected to the bearing limit seat 34 by bolts; a bearing sleeve 3141 is provided in the fixed limit seat 314, and one end of the bearing sleeve 3141 is connected to the elastic element 33, so that the elastic element 33 can rotate with the bearing sleeve 3141, and the other end can be connected to the torsion plug 231, and the bearing sleeve 3141 can be driven to rotate by the torsion plug 231; a second connecting lock 3142 is further provided on the fixed limit seat 314, and the second connecting lock 3142 is connected to the fixed limit seat 314 by bolts, so that when torque is applied to the folding rudder 6, there is no need to change the positions of the bearing limit seat 34 and the fixed limit seat 314, and the direction of the torque applied to the folding rudder 6 can be controlled.

[0070] When a load needs to be applied to the folding rudder 6, after the folding rudder 6 is folded by the rotating unit 2, the rotating unit 2 is moved along the first guide rail 25 to one side of the lifting platform 311, and the lifting drive member 36 is used to lift the lifting platform 311 until the axes of the bearing limit seat 34 and the fixed limit seat 314 are collinear with the axis of the connecting shaft 23, so that one end of the elastic element 33 is connected to the bearing limit seat 34, and the other end is connected to the fixed limit seat 314, and the position of the fixed limit seat 314 is adjusted along the adjusting groove 3111 so that the torsion plug 231 is inserted into the bearing sleeve 3141, and the first connecting lock 341 is tightened by tightening the bolt to press the bearing limit seat 34, so that the end of the elastic element 33 located at the bearing limit seat 34 remains fixed, and the servo motor 21 is started to make the end of the elastic element 33 located at the fixed bearing seat 314 rotate along the bearing sleeve 3141, so that the elastic element 33 is twisted, and the rotation angle of the bearing sleeve 3141 is the same as the rotation angle when the folding rudder 6 is folded. The torque generated by the twisting of the elastic element 33 is measured by the torque sensor 221, thereby detecting the magnitude of the torque applied by the elastic element 33 during the unfolding of the folding rudder 6. The number, size and other parameters of the elastic element 33 are adjusted according to the output torque magnitude result so that the torque generated by the twisting of the elastic element 33 reaches a predetermined value.

[0071] When it is necessary to apply positive torque to the folding rudder 6, the rotation direction of the servo motor 21 is opposite to the folding direction of the folding rudder 6. The bolt on the second connecting lock 3142 is tightened so that the second connecting lock 3142 presses the bearing sleeve 3141 tightly to limit the rotation of the bearing sleeve 3141, thereby keeping the elastic element 33 in a twisted state. The slide 24 is adjusted to move the twisting plug 231 out of the bearing sleeve 3141. The lifting platform 311 is moved along the second guide rail 32 to connect the bearing limit seat 34 to the folding rudder 6. The bolt on the first connecting lock 341 is loosened so that the first connecting lock 341 releases the fixation of the bearing limit seat 34, and the folding rudder 6 is controlled to unfold. The elastic element 33 is reset to drive the bearing limit seat 34 to apply positive torque to the folding rudder 6.

[0072] When it is necessary to apply reverse torque to the folding rudder 6, the slide 24 is adjusted to remove the torsion plug 231 from the bearing sleeve 3141, resetting the elastic element 33. The bolts on the second connecting lock 3142 are tightened, causing the second connecting lock 3142 to press against the bearing sleeve 3141, restricting the rotation of the bearing sleeve 3141 and keeping the end of the elastic element 33 connected to the bearing sleeve 3141 fixed. The bearing stopper 34 is connected to the folding rudder 6, and the bolts on the first connecting lock 341 are loosened, allowing the bearing stopper 34 to rotate as the folding rudder 6 is deployed. This controls the deployment of the folding rudder 6 and causes the elastic element 33 to twist, thereby applying a load to the folding rudder 6 during its deployment.

[0073] Compared with the prior art, the time detection device of the folding rudder of the present invention can control the torque of the load applied to the folding rudder 6 by setting the torque load applying unit 3, thereby simulating the loaded and unfolded state of the folding rudder 6; the lifting platform assembly 31 can slide along the lifting slide rail 351 under the action of the lifting drive member 36, so that the lifting platform assembly 31 can be adjusted according to whether the folding rudder 6 needs to be loaded; the lifting platform assembly 31 can slide along the second guide rail 32 under the action of the second linear drive member 37, so as to facilitate the connection between the torque load applying unit 3 and the folding rudder 6; by setting the elastic element 33, the bearing limit seat 34, the fixed limit seat 314 and the torque sensor 22 1. The number, combination and size of the elastic elements 33 can be adjusted according to the value of the torque sensor 221, thereby changing the torque applied to the folding rudder 6, facilitating the adjustment of the torque on the folding rudder 6 and achieving controllable load on the folding rudder 6. The time monitoring unit 5 is provided to monitor the deployment time of the folding rudder 6. The monitoring platform 53 and the signal transceiver 54 can be adjusted according to the position and model of the folding rudder 6, which is easy to use and has strong applicability. The PLC control panel is provided to control the first linear drive 26, the servo motor 21, the lifting drive 36, the second linear drive 37 and the third linear drive 43, which is easy to operate and easy to use.
