Description

Technical Field

[0001] The present invention relates to the technical field of transportation equipment, and particularly relates to an electric hook unhooking and parking system and a method for a torpedo car and the hook unhooking and parking method thereof. Background Art

[0002] A torpedo car is a large-scale molten iron transportation equipment, which has no driving mechanism itself and is driven by the power of an external locomotive. The locomotive and the torpedo car are connected by a coupler. The existing hook unhooking and hooking devices of torpedo cars are basically operated manually. In the hook unhooking process, the hook tongue pin is manually lifted upward to unlock the hook tongue, and the torpedo car is separated from the locomotive. In the hooking process, after the torpedo car and the locomotive complete the hooking action, the hook tongue pin drops under the action of gravity to lock the hook tongue. After the hook unhooking process is completed and the torpedo car is separated from the locomotive, due to reasons such as the possible slope of the track, iron shoes are usually placed manually at the wheels to prevent the torpedo car from slipping. However, both the hook unhooking and hooking devices and preventing the torpedo car from slipping require manual operation, resulting in low efficiency. Summary of the Invention

[0069] As Figures 2 to 5 shown, the electric hook uncoupling and parking system for a torpedo car according to an embodiment of the present invention is used to be installed on the torpedo car 100. A coupler is provided on the torpedo car 100. The coupler includes a hook tongue 110, a hook tongue pin 120, and a hook body 160. The hook tongue 110 is rotatably connected to the hook body 160, and the hook tongue pin 120 is drivingly connected to the hook tongue 110. The hook tongue 110 is used for hooking with a locomotive. As Figure 1 shown, it includes: a control module 200, a hook tongue state detection module 300, a first driving mechanism 400, a hook uncoupling and coupling mechanism 500, a first position detection module 600, a second driving mechanism 700, a parking mechanism 800, and a power supply module. The hook tongue state detection module 300 is used to detect the opening and closing state of the hook tongue 110. The output end of the hook tongue state detection module 300 is electrically connected to the input end of the control module 200. The output end of the control module 200 is electrically connected to the control end of the first driving mechanism 400. As Figures 6 to 8 shown, the hook uncoupling and coupling mechanism 500 includes a first transmission member, a first lead screw 530, and a lifting ring 540. The first driving mechanism 400 is connected to the first lead screw 530 through the first transmission member. The lifting ring 540 is installed on the hook tongue pin 120. The bottom of the first lead screw 530 is connected to the lifting ring 540 through a connecting member 570. The output end of the first position detection module 600 is electrically connected to the input end of the control module 200. The first position detection module 600 is used to detect the position of the first lead screw 530. The output end of the control module 200 is electrically connected to the control end of the second driving mechanism 700. The parking mechanism 800 is installed on the torpedo car 100 to perform parking braking on the torpedo car 100. The second driving mechanism 700 is drivingly connected to the parking mechanism 800. The power supply module is used for power supply.

[0070] The control module 200 is used to execute the hook uncoupling and parking method. As Figure 15 shown, the hook uncoupling and parking method includes but is not limited to step S100, step S200, step S300, and step S400.

[0071] Step S100: After receiving the hook uncoupling instruction, control the second driving mechanism 700 to drive the parking mechanism 800 to perform parking braking on the torpedo car 100;

[0072] Step S200: Control the first driving mechanism 400 to drive the first lead screw 530 to move upward from the first preset position to the second preset position. The first lead screw 530 drives the hook tongue pin 120 to move upward through the lifting ring 540. The first preset position is the position where the first lead screw 530 does not lift the lifting ring 540, and the second preset position is the position where the first lead screw 530 lifts the lifting ring 540 and the hook tongue pin 120, so that the hook tongue 110 is unlocked.

[0073] Step S300: Detect the position of the first lead screw 530 through the first position detection module 600. When the first lead screw 530 reaches the second preset position, control the first driving mechanism 400 to drive the first lead screw 530 to move downward to the first preset position. After the ladle car 100 and the locomotive complete the coupling action, the hook tongue pin 120 drops the pin by its own gravity, so that the hook tongue 110 is locked.

[0074] Step S400: Detect the opening and closing state of the hook tongue 110 through the hook tongue state detection module 300. If it is detected that the hook tongue 110 is in the locked state, control the second driving mechanism 700 to drive the parking mechanism 800 to release the parking brake on the ladle car 100.

[0075] After receiving the decoupling instruction, control the second driving mechanism 700 to drive the parking mechanism 800 to apply the parking brake to the ladle car 100, control the first driving mechanism 400 to drive the first lead screw 530 to move upward from the first preset position to the second preset position. The first lead screw 530 drives the hook tongue pin 120 to move upward through the lifting ring 540, so that the hook tongue 110 is unlocked. Detect the position of the first lead screw 530 through the first position detection module 600. When the first lead screw 530 reaches the second preset position, control the first driving mechanism 400 to drive the first lead screw 530 to move downward to the first preset position. At this time, the lifting ring 540 is not lifted by the first lead screw 530, and the lifting ring 540 no longer applies an upward pulling force to the hook tongue pin 120. After the ladle car 100 and the locomotive complete the coupling action, the hook tongue pin 120 drops the pin by its own gravity, and the hook tongue 110 is locked. Detect the opening and closing state of the hook tongue 110 through the hook tongue state detection module 300. If it is detected that the hook tongue 110 is in the locked state, control the second driving mechanism 700 to drive the parking mechanism 800 to release the parking brake on the ladle car 100. The electric decoupling and coupling parking system of the ladle car in the embodiment of the present invention can automatically complete the decoupling and coupling operations, prevent the ladle car 100 from running away, and does not require manual operation, improving the efficiency.

[0076] The hook tongue state detection module 300 is a distance sensor. The distance sensor is installed on the hook tongue 110, and the opening and closing degree of the hook tongue 110 is detected through the distance sensor, so as to detect the opening and closing state of the hook tongue 110.

[0077] Such as Figure 5As shown, the first position detection module 600 includes a first limit switch 610 and a second limit switch 620. The output end of the first limit switch 610 is electrically connected to the input end of the control module 200, and the output end of the second limit switch 620 is electrically connected to the input end of the control module 200. The first limit switch 610 is set at a first preset position, and the second limit switch 620 is set at a second preset position. A contact rod 532 is arranged on the first lead screw 530, and the contact rod 532 is located between the first limit switch 610 and the second limit switch 620.

[0078] When the first lead screw 530 moves upward, the contact rod 532 touches the second limit switch 620, and the second limit switch 620 feeds back a signal to the control module 200. The control module 200 then detects that the first lead screw 530 has moved to the second preset position. When the first lead screw 530 moves downward, the contact rod 532 touches the first limit switch 610, and the first limit switch 610 feeds back a signal to the control module 200. The control module 200 then detects that the lead screw has moved to the first preset position.

[0079] As Figure 5 shown, it further includes a third position detection module 640. The third position detection module 640 is a third limit switch. The third limit switch is installed at the bottom of the hook body 160. When the hook tongue pin 120 drops, that is, the hook tongue pin 120 drops back into the hook body 160 and touches the third limit switch, the third limit switch feeds back a signal to the control module 200. The control module 200 then detects that the hooking is successful.

[0080] As Figures 9 to 10 shown, the first driving mechanism 400 is a first motor. The first transmission member includes a worm 510 and a worm gear 520. The output shaft of the first motor is connected to one end of the worm 510. The worm 510 meshes with the worm gear 520. A first nut is installed inside the worm gear 520, and the first lead screw 530 is threadedly connected to the first nut. The first driving mechanism 400 is a first motor. The first transmission member includes a worm 510 and a worm gear 520. The output shaft of the first motor is connected to one end of the worm 510. The worm 510 meshes with the worm gear 520. A first nut is installed inside the worm gear 520, and the first lead screw 530 is threadedly connected to the first nut.

[0081] The output shaft of the first motor rotates forward, driving the worm 510 to rotate forward. The worm 510 drives the worm wheel 520 to rotate forward. The worm wheel 520 makes the first lead screw 530 move upward through the first nut. The first lead screw 530 lifts the lifting ring 540 upward, and further makes the latch pin 120 move upward. Since the first lead screw 530 moves vertically upward, the lifting ring 540 vertically lifts the latch pin 120 upward. The resistance of the latch pin 120 to the latch 110 is small, and the latch 110 is easily pulled up. When the output shaft of the first motor rotates in reverse, it drives the worm 510 to rotate in reverse. The worm 510 drives the worm wheel 520 to rotate in reverse. The worm wheel 520 makes the first lead screw 530 move downward through the first nut.

[0082] As Figures 9 to 10 shown. The unhooking and hooking mechanism 500 further includes a first box body 550. The first lead screw 530 is installed in the first box body 550 through a bearing 580. A guide groove 531 is provided on the first lead screw 530, and a guide key 551 is provided on the first box body 550. The width of the guide key 551 corresponds to the width of the guide groove 531, and the guide key 551 extends into the guide groove 531. When the worm wheel 520 rotates, it drives the first nut to rotate, thereby making the first lead screw 530 move up and down. Since the guide key 551 on the first box body 550 is fixed on the first box body 550 and is located in the guide groove 531, under the limiting action of the guide groove 531, the first lead screw 530 will not rotate with the first nut when moving up and down, and the operation is stable.

[0083] As Figures 6 to 8 shown, it further includes a handwheel mechanism 560. The rotating shaft of the handwheel mechanism 560 is fixedly connected to the other end of the worm 510. By manually rotating the handwheel mechanism 560, the worm 510 can be driven to rotate. The worm 510 drives the worm wheel 520 to rotate. The worm wheel 520 makes the first lead screw 530 move up and down through the first nut.

[0084] As Figure 11 shown, the parking mechanism 800 includes a bracket 810, a first brake arm 820, a second brake arm 830, a first brake shoe 840, and a second brake shoe 850. One end of the bracket 810 is hinged to the middle of the first brake arm 820, and the other end of the bracket 810 is hinged to the middle of the second brake arm 830. The first brake shoe 840 is installed at the bottom end of the first brake arm 820, and the second brake shoe 850 is installed at the bottom end of the second brake arm 830. The first brake shoe 840 and the second brake shoe 850 are oppositely arranged on both sides of the wheel 130 of the torpedo car 100. The second drive mechanism 700 is connected to the top end of the second brake arm 830 through a second transmission member.

[0085] Driven by the second driving mechanism 700, the first brake arm 820 and the second brake arm 830 drive the first brake shoe 840 and the second brake shoe 850 respectively. The first brake shoe 840 and the second brake shoe 850 move relative to each other or towards each other, thereby clamping or releasing the wheel 130 to achieve parking braking or release of parking braking.

[0086] As Figures 3 to 4 shown, a flange is installed at one end of the axle 140 of the torpedo car 100, and a mounting seat 150 is welded on the flange. The parking mechanism 800 is installed on the mounting seat 150. If the parking mechanism 800 is installed on the vehicle body by traditional installation methods, the vehicle body will shift relative to the wheel 130 during the operation of the torpedo car 100, and the wheel 130 is likely to wear the first brake shoe 840 and the second brake shoe 850. However, by installing the parking mechanism 800 on the axle 140 through the flange and the mounting seat 150, it is not affected by the shift of the vehicle body, and it can avoid the wheel 130 from wearing the first brake shoe 840 and the second brake shoe 850 when the torpedo car 100 is running.

[0087] As Figure 11 shown, the second driving mechanism 700 is a second motor. The second transmission components include a gear set 865, a second lead screw 861, a spring piston 862 and a cylinder block 863. The gear set 865 is installed in the second box body 866. The second box body 866 is installed at the top of the first brake arm 820. The output shaft of the second motor is connected to the second lead screw 861 through the gear set 865. The cylinder block 863 is installed on the second box body 866. The spring piston 862 is movably installed in the cylinder block 863. A second nut 864 is installed on the spring piston 862. The second lead screw 861 is threadedly connected to the second nut 864. The spring piston 862 is connected to the top of the second brake arm 830.

[0088] When the output shaft of the second motor rotates forward, it drives the gear set 865 to rotate forward, causing the second lead screw 861 to rotate forward. Under the action of the second nut 864, the spring piston 862 moves towards the second brake arm 830, thereby pushing the first brake arm 820 and the second brake arm 830, causing the first brake shoe 840 and the second brake shoe 850 to move towards the wheel 130 and clamp the wheel 130. When the output shaft of the second motor rotates reversely, it drives the gear set 865 to rotate reversely, causing the second lead screw 861 to rotate reversely. Under the action of the second nut 864, the spring piston 862 moves away from the second brake arm 830, thereby pulling the first brake arm 820 and the second brake arm 830, causing the first brake shoe 840 and the second brake shoe 850 to move away from the wheel 130 and release the wheel 130.

[0089] As Figure 11As shown, it further includes a second position detection module 630. The second position detection module 630 includes a fourth limit switch 631 and a fifth limit switch 632. A touch plate 867 is installed on the spring piston 862, and the touch plate 867 is located between the fourth limit switch 631 and the fifth limit switch 632.

[0090] When the spring piston 862 moves away from the second brake arm 830 and the touch plate 867 touches the fourth limit switch 631, the first brake shoe 840 and the second brake shoe 850 release the wheel 130. The fourth limit switch 631 sends a signal to the control module 200, and the control module 200 then detects that the parking brake is released. When the spring piston 862 moves towards the second brake arm 830 and the touch plate 867 touches the fifth limit switch 632, the first brake shoe 840 and the second brake shoe 850 clamp the wheel 130. The fifth limit switch 632 sends a signal to the control module 200, and the control module 200 then detects that the parking brake is completed.

[0091] As Figures 12 to 13 shown, the power supply module includes an electric energy storage mechanism 910 and a kinetic energy conversion mechanism 920. The kinetic energy conversion mechanism 920 includes a driving wheel 921, a driven wheel 922, a chain 923, and a generator 924. The driving wheel 921 is installed on the wheel 130 of the torpedo car 100 through a flange. The driven wheel 922 is installed on the rotating shaft of the generator 924. The driving wheel 921 and the driven wheel 922 are connected to each other through the chain 923. The output end of the generator 924 is electrically connected to the input end of the electric energy storage mechanism 910.

[0092] When the torpedo car 100 is running, the wheel 130 drives the driving wheel 921 to rotate. The driving wheel 921 drives the rotating shaft of the generator 924 to rotate through the driven wheel 922. The generator 924 converts kinetic energy into electric energy and transports it into the electric energy storage mechanism 910. The electric energy storage mechanism 910 is used for power supply.

[0093] It further includes a display module 210. The output end of the control module 200 is electrically connected to the control end of the display module 210. The display module 210 includes a first indicator light, a second indicator light, and a third indicator light. When the first lead screw 530 reaches or leaves the first preset position, the first display light is lit or extinguished. When the first lead screw 530 reaches or leaves the second preset position, the second display light is lit or extinguished. When the latch pin 120 falls back into the hook body 160 and touches the third limit switch, the third indicator light is lit.

[0094] As Figure 14As shown, a reset spring mechanism 170 is provided on the coupler, a first limiting member 171 is provided on the coupler body 160, a second limiting member 172 is provided on the coupler tongue 110, one end of the reset spring mechanism 170 extends and abuts against the first limiting member 171, and the other end of the reset spring mechanism 170 extends and abuts against the second limiting member 172.

[0095] When hooking up, when the coupler tongue pin 120 falls back into the coupler body 160, the coupler tongue 110 rotates inward around the coupler body 160, the coupler tongue 110 is locked, the first limiting member 171 abuts against one end of the reset spring mechanism 170, the second limiting member 172 compresses the other end of the reset spring mechanism 170, and the reset spring mechanism 170 is in a compressed state. When unhooking, the coupler tongue 110 rotates outward around the coupler body 160, the coupler tongue 110 opens, the two ends of the reset spring mechanism 170 are reset, and the coupler tongue 110 is kept in a fully open state until the coupler tongue pin 120 falls back into the coupler body 160.

[0096] As Figure 15 shown, the method for hooking / unhooking and parking according to an embodiment of the present invention includes:

[0097] Step S100: After receiving an unhooking instruction, control the second driving mechanism 700 to drive the parking mechanism 800 to perform parking braking on the torpedo car 100;

[0099] Step S300: Detect the position of the first lead screw 530 through the first position detection module 600. When the first lead screw 530 reaches the second preset position, control the first driving mechanism 400 to drive the first lead screw 530 to move downward to the first preset position. After the torpedo car 100 and the locomotive complete the coupling action, the coupler tongue pin 120 drops the pin by its own gravity, so that the coupler tongue 110 is locked;

[0100] In this step, when the first lead screw 530 reaches the second preset position, after delaying for N seconds, control the first driving mechanism 400 to drive the first lead screw 530 to move downward to the first preset position. N is valued according to the application scenario. For example, N is 2.

[0101] Step S400: Detect the opening and closing state of the coupler tongue 110 through the coupler tongue state detection module 300. If it is detected that the coupler tongue 110 is in a locked state, control the second driving mechanism 700 to drive the parking mechanism 800 to release the parking braking on the torpedo car 100.

After the torpedo car 100 and the locomotive complete the coupling action, the hook tongue pin 120 drops the pin by its own gravity, and the hook tongue 110 is locked. Detect the opening and closing state of the hook tongue 110 through the hook tongue state detection module 300. If it is detected that the hook tongue 110 is in the locked state, control the second driving mechanism 700 to drive the parking mechanism 800 to release the parking braking on the torpedo car 100. The uncoupling and coupling parking method of the embodiment of the present invention can automatically complete the uncoupling and coupling operations, prevent the torpedo car 100 from running away, and improve the efficiency without manual operation.

[0103] According to the computer-readable storage medium of the embodiment of the present invention, a program executable by a processor is stored therein. When the program executable by the processor is executed by the processor, it is used to implement the uncoupling and coupling parking method as described above.

After the torpedo car 100 and the locomotive complete the coupling action, the hook tongue pin 120 drops the pin by its own gravity, and the hook tongue 110 is locked. Detect the opening and closing state of the hook tongue 110 through the hook tongue state detection module 300. If it is detected that the hook tongue 110 is in the locked state, control the second driving mechanism 700 to drive the parking mechanism 800 to release the parking braking on the torpedo car 100. The computer-readable storage medium of the embodiment of the present invention can automatically complete the uncoupling and coupling operations, prevent the torpedo car 100 from running away, and improve the efficiency without manual operation.
