DETAILED DESCRIPTION

[0024] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0025] See also Figure 1-7 The present invention provides a technical solution: an unmanned hook-removing robot system and method based on robotic technology, including a hook-removing mechanism and a robot control system. The hook-removing mechanism includes an electric track 1, a slider 2, a chamber 3, a hook-removing part, and a hook lifting pin;

[0026] The slider 2 is slidably connected to the upper part of the electric track 1, and the chamber 3 is fixedly installed on the upper part of the slider 2. The hook removing part includes a cylinder 31, a back plate 32, a motor 33, a gear 331, a connecting shaft 34, a fixing plate 35, a hook removing disk 36 and a hook removing rod 37;

[0027] The cylinder 31 is fixedly mounted on the inner wall of the chamber 3. The back plate 32 is fixedly connected to the output end of the cylinder 31 and is located inside the chamber 3. The motor 33 is fixedly mounted on one side of the back plate 32. The gear 331 is fixedly connected to the output end of the motor 33. The fixing plate 35 is fixedly connected to the back plate 32 and is connected to the connecting shaft 34 in the middle by a bearing. A toothed disc 341 is fixed to the outer side of the end of the connecting shaft 34, and the toothed disc 341 and the gear 331 are meshed with each other. The unhooking disc 36 and the unhooking rod 37 are both fixedly mounted on the outer side of the front end of the connecting shaft 34, and the unhooking rod 37 is located in front of the unhooking disc 36.

[0028] After the coal carriage stops, the electric rail 1 drives the chamber 3 to move through the slider 2, and the chamber 3 drives the hook plate 36 to move until it moves to the left position of the hook lifting pin and stops. At this time, the cylinder 31 runs, driving the back plate 32 to move forward. The back plate 32 drives the connecting shaft 34 to move forward through the fixed plate 35, and the connecting shaft 34 drives the hook plate 36 to move forward until it moves to the left side of the hook lifting pin. After that, the motor 33 runs, driving the gear 331 to rotate, the gear 331 drives the toothed plate 341 to rotate through meshing, the toothed plate 341 drives the connecting shaft 34 to rotate, and the connecting shaft 34 drives the hook plate 36 to rotate. At the same time, the hook removing rod 37 rotates around the center, and the hook removing rod 37 pushes the hook lifting pin to lift and remove the hook. During the hook removing process, the hook removing plate 36 has been rolling on the left side of the hook lifting pin, so that the hook lifting pin can be relatively loose, which is convenient for lifting the hook, thereby relatively reducing the probability of the hook lifting pin getting stuck. The whole process of hook removing is automated, convenient and efficient.

[0029] The robot control system includes a control module, a force sensing module, a strength enhancement module, and a mode switching module;

[0030] A telescopic joint 371 is fixed to the outer end of the unhooking rod 37, and a push rod 372 is fixed to the outer end of the telescopic joint 371. The force sensing module is arranged inside the push rod 372 and is electrically connected to the strength enhancement module and the mode switching module. The control module is electrically connected to the cylinder 31 and the motor 33 respectively. The strength enhancement module and the mode switching module are both electrically connected to the motor 33.

[0031] The control module is used to control the reciprocating motion of the cylinder 31, thereby controlling the forward and backward movement and retreat of the hook-removing rod 37. The force sensing module is used to sense the reaction force of the hook lifting pin through the push rod 372. The strength enhancement module is used to increase the power of the motor 33 and control the power of the motor 33 according to the magnitude of the reaction force. The mode switching module is used to switch the motor 33 between counterclockwise rotation and alternating counterclockwise and clockwise rotation modes, and the amplitude of the alternating counterclockwise and clockwise rotation is gradually increased.

[0032] When the hook-removing rod 37 rotates around the center, the telescopic joint 371 drives the push rod 372 to rotate, so that the push rod 372 presses against the left side of the hook lifting pin, so that the hook is lifted, and the hook-removing work is completed. During the hook-removing process, when the force applied to the push rod 372 is stable, it means that the hook lifting pin can lift the hook smoothly without any jamming or deadlocking. When the force applied to the push rod 372 suddenly increases, it means that the hook lifting pin is jammed. At this time, the motor 33 rotates alternately in the reverse direction, so that the push rod 372 continuously loosens the hook lifting pin, making it easier to unhook, thereby relatively improving the hook-removing efficiency. The counterclockwise and clockwise rotation amplitudes gradually increase, and the hook lifting pin can be removed step by step. By controlling the power of the motor 33, an impact force can be generated each time the push rod 372 presses against the hook lifting pin, making it more convenient and quick to remove the hook.

[0033] A sector tooth 332 is fixed to one side of the gear 331, a hydraulic chamber 38 is fixed to one side of the back plate 32, a hydraulic plate 381 is slidably connected to the inner wall of the hydraulic chamber 38, a gear rod 382 is fixed to the bottom of the hydraulic plate 381, and the sector tooth 332 is engaged with the gear rod 382 after rotation;

[0034] The connecting shaft 34 passes through the front and back, and a telescopic rod 39 is provided inside. The telescopic rod 39 is fixedly connected to one side of the back plate 32. The interior of the hook-removing plate 36 is hollow and communicates with the interior of the connecting shaft 34. A plurality of ball rods 361 are distributed and slidably connected around the hook-removing plate 36. Both ends of the ball rods 361 are spherical. The outer sides of the ball rods 361 are fixed with limit blocks. A card block is fixed to the inner wall of the hook-removing plate 36. The ball rods 361 are inserted into the card block, and a spring 362 is provided between the card block and the limit block. After the telescopic rod 39 is extended, it contacts the inner ends of the ball rods 361.

[0035] The top of the hydraulic chamber 38 is connected to the telescopic rod 39 via a pipe. The top of the hydraulic plate 381 is filled with hydraulic oil. The front end of the telescopic rod 39 is spherical.

[0036] When the motor 33 continues to rotate counterclockwise, the gear 331 drives the fan gear 332 to rotate around its center until the fan gear 332 meshes with the gear rod 382, driving the gear rod 382 to move upward, and the gear rod 382 drives the hydraulic plate 381 to slide upward along the inner wall of the hydraulic chamber 38. The hydraulic oil is squeezed and enters the telescopic rod 39 through the pipeline to extend it. The telescopic rod 39 extends, and the front end spherical part of the telescopic rod 39 contacts the inner end of the ball rod 361. The ball rod 361 slides outward, and the spring 362 is deformed by the force. At this time, the ball rod 361 can push the hook lifting pin outward, so as to test whether the hook lifting pin is stuck. If it is slightly stuck, it can be loosened. After the subsequent push rod 372 contacts the hook lifting pin, it will not be suddenly stressed, thereby preventing the wrong mode switching of the motor 33 from causing the hook unhooking time to be prolonged and affecting the hook unhooking efficiency.

[0037] When the force acting on the push rod 372 suddenly increases, the hook lifting pin is seriously stuck, thereby driving the motor 33 to switch the operating mode. The motor 33 first rotates counterclockwise for several circles, and then rotates clockwise for the same number of circles, and the number of circles of alternating clockwise and counterclockwise rotation gradually increases, thereby slowly impacting the hook lifting pin to remove the hook. When the motor 33 rotates alternately clockwise and counterclockwise, the fan teeth 332 also rotate alternately clockwise and counterclockwise, thereby engaging the gear rod 382 to move up and down, driving the hydraulic plate 381 to slide up and down along the inner wall of the hydraulic chamber 38, continuously injecting hydraulic oil into the telescopic rod 39 and then extracting it, so that the telescopic rod 39 can reciprocate back and forth, and the front end of the telescopic rod 39 continuously supports the ball rod 361, causing it to extend and retract, so that when the hook lifting pin is stuck, it can be continuously loosened, thereby speeding up the hook removal speed and further improving the hook removal efficiency.

[0038] The lower pipe of the hydraulic chamber 38 is connected to the air chamber, and the lower part of the air chamber is connected to the pipe of the expansion joint 371, and a pressure valve is provided in the pipe. The lower part of the hydraulic chamber 38 is connected to the external pipe, and a one-way valve is provided in the pipe.

[0039] The expansion joint 371 is connected to the external control valve pipeline;

[0040] When the hydraulic plate 381 slides up and down along the inner wall of the hydraulic chamber 38, gas is extracted from the outside through the pipeline and injected into the air chamber until the pressure in the air chamber reaches the pressure limit of the pressure valve, thereby causing the pressure valve to open, and the gas quickly enters the telescopic joint 371, causing it to quickly extend, thereby driving the push rod 372 to extend quickly, and instantly pushing out the hook lifting pin. At this time, the final stage of hook removal is reached, so that through a one-time hook lifting, the efficiency of hook removal can be fully accelerated, avoiding the phenomenon of low hook removal efficiency when the hook lifting pin is stuck.

[0041] The operation method includes the following steps:

[0042] Step S1: The electric track 1 drives the chamber 3 via the slider 2 to move until the hook removal plate 36 is located on the left side of the hook lifting pin and stops;

[0043] Step S2: The cylinder 31 operates, and the hook-removing plate 36 extends to the left side of the hook lifting pin and contacts it. Then, the motor 33 operates, causing the hook-removing plate 36 to rotate. At the same time, the hook-removing rod 37 drives the push rod 372 to rotate around the center of the hook-removing plate 36. If the push rod 372 continues to rotate smoothly, the process proceeds to step S4. Otherwise, if the push rod 372 is stuck, the process proceeds to step S3.

[0044] Step S3: The push rod 372 senses the reaction force of the hook lifting pin, and the mode switching module switches the operating mode of the motor 33 from continuous counterclockwise rotation to alternating counterclockwise and clockwise rotation, with the amplitude of the alternating counterclockwise and clockwise rotation gradually increasing. At the same time, the power of the motor 33 is controlled according to the magnitude of the reaction force of the push rod 372;

[0045] Step S4: After the hook is removed, the control module controls the motor 33 to reset, and then controls the cylinder 31 to reset.

[0046] In step S3, the force acting on the top rod 372 sensed by the force sensing module is set to ;

[0047] Then when hour, The stabilizing force on the ejector rod 372 is: the motor 33 is in a continuous counterclockwise stable rotation mode;

[0048] when When: the motor 33 is in a counterclockwise and clockwise alternating rotation mode, and the amplitude of the alternating rotation gradually increases;

[0049] When switching between these two modes, when the motor 33 continues to rotate steadily counterclockwise, the hook is removed normally to ensure the efficiency of hook removal. When the hook lifting pin is stuck, a hook removal method is switched to avoid the phenomenon that the hook cannot be removed smoothly due to the jamming of the hook lifting pin. Regardless of whether the hook lifting pin is stuck, the hook can be removed quickly and efficiently.

[0050] In step S3, when hour: , is the counterclockwise rotation output power of the motor 33, is the maximum force on the ejector pin 372, is the maximum output power of the motor 33 in counterclockwise rotation;

[0051] That is, the greater the force on the push rod 372, the greater the counterclockwise rotation power of the motor 33, thereby making the force of the push rod 372 on the hook lifting pin greater;

[0052] When the push rod 372 rotates counterclockwise around the center to push the hook lifting pin upward, the greater the force on the push rod 372, the greater the force of the motor 33 when it rotates counterclockwise next time, which can further accelerate the speed of hook removal. On the contrary, while ensuring the efficiency of hook removal, it reduces energy consumption, reduces structural wear, and increases service life.
