The pushing piece movably passes through the support plate 10 and extends to the bottom of the impact sleeve 8. The pushing piece includes a knocking part, which is arranged on the outside of the servo motor 15 and extends to the bottom of the impact sleeve 8.

[0091] Specifically, the telescopic end of the electric rod 11 is connected to the connecting plate 12 through a connecting component and a fixing component, and the lower end of the connecting plate 12 is welded to the upper end of the telescopic plate 13.

[0093] In actual application of this embodiment: the staff can control the extension of the electric rod 11 according to the actual needs, so that the electric rod 11 pushes the connecting plate 12, the telescopic plate 13 and the supporting leg 14 to move in a direction away from the connecting sleeve 9 through the connecting parts and the fixing parts under the support of the support plate 10, thereby adjusting the gap between the multiple supporting legs 14, so that the supporting legs 14 can be conveniently placed in a variety of work locations. The staff can move the removal device according to the actual needs, so that the screw 6, the insertion rod 5 and the sleeve 18 can be inserted into the hole where the pin to be removed is located, and Support the support leg 14 at the work site so that the connecting sleeve 9 can support the T-rod 2 to remain vertical. Then the staff needs to control the servo motor 15 to start, so that it uses the driving end to drive the inclined rubber wheel 16 to rotate. The inclined rubber wheel 16 will use friction to push the inclined wheel 17 to rotate. The inclined wheel 17 will use the rotational power to drive the connecting tube 3, T-rod 2, one-way valve 50, longitudinal rod 4, insertion rod 5 and screw 6 to rotate together, so that the screw 6 uses the gravity and rotational power of the components above it to be threadedly connected to the pin. At the same time, the longitudinal rod 4 will use the rotational power to push the sleeve 18 to rotate together through the guide block 20.

[0094] The staff can use the sleeve 21 to drive the threaded ring 22 to rotate according to the size requirements of the pin, so that the threaded ring 22 is threadedly separated from the sleeve 18, and then use the threaded action to separate the screw 6 from the insertion rod 5, and replace the screw 6 and sleeve 21 with the appropriate size of the pin as needed.

[0095] As a preferred embodiment of the present invention, the push member includes:

[0096] The sleeve 18 is sleeved on the outside of the longitudinal rod 4 and the insertion rod 5 and is connected to the longitudinal rod 4 through a guide component;

[0097] The abutment 21 is threadedly connected to the lower end of the sleeve 18 and is located outside the screw 6;

[0098] The pressure plate 24 is fixed to one side of the cylinder through a connecting component;

[0099] The push rod 25 is symmetrically fixed on the pressure plate 24, and the end portion is arc-shaped.

[0100] Specifically, a guide groove 19 is symmetrically opened on the inner side of the sleeve 18, and a guide block 20 is symmetrically welded on the outer side of the longitudinal rod 4, and the guide block 20 extends to the inner side of the guide groove 19 to provide a moving guide for the sleeve 18 and support the guide cylinder. A threaded ring 22 is welded on the upper end of the resistance cylinder 21, and the threaded ring 22 is threadedly connected to the lower end of the sleeve 18. The sleeve 18 can use the thread action to provide support for the resistance cylinder 21. A side plate 23 is fixed to the outer side of the sleeve 18, and the side plate 23 is welded to the pressure plate 24. The side plate 23 can provide support for the pressure plate 24 through the sleeve 18, so that the pressure plate 24 can firmly support the push rod 25, and the push rod 25 can use external force to push the push ring 27.

[0101] The pieces include:

[0102] The movable opening 26 passes through the inclined rubber wheel 16 and is opened in a ring shape;

[0103] The annular groove 29 is formed in the bevel rubber wheel 16 and passes through the outer side of the bevel rubber wheel 16 and is connected to the movable opening 26;

[0104] Push-to-connect parts are provided through the movable opening 26;

[0105] The magnetic push component is arranged inside the inclined rubber wheel 16 and located outside the inclined wheel 17.

[0106] Specifically, the inclined rubber wheel 16 can provide space for the movable opening 26 and the annular groove 29 , the movable opening 26 can provide movement space for the push ring 27 and the support rod 28 , and the push rod 25 can use the arc-shaped end to provide rotational support for the push ring 27 .

[0107] Push-to-connect parts include:

[0108] A push ring 27 is movably arranged on the inner side of the movable opening 26 and has an arc on the outer side;

[0109] There are multiple support rods 28, which are evenly and symmetrically welded to the push ring 27 and pass through the upper end of the movable opening 26;

[0110] Connecting rod 35, welded to support rod 28;

[0111] Support block 36, welded to connecting rod 35;

[0112] The plug 37 is fixed on the support block 36 .

[0113] Specifically, the push ring 27 can use external force to push the support rod 28 and the connecting rod 35 to move upward, so that the connecting rod 35 drives the support block 36 and the plug 37 to move upward together.

[0114] Magnetic push parts include:

[0115] There are multiple T-grooves 31, which are provided in the inclined rubber wheel 16 and communicate with the annular groove 29;

[0116] The inclined arc plate 30 has multiple support rings 38 evenly distributed on the inner side of the annular groove 29, with inclined surfaces at both ends and guided and connected to the T-slot 31, and the end close to the movable opening 26 extends into the movable opening 26;

[0117] The magnet 33 is fixed to the end of the inclined arc plate 30 away from the movable opening 26;

[0118] The magnetic ring 34 is embedded on the outer side of the bevel wheel 17 and corresponds to the position of the magnet 33 .

[0119] Specifically, a T-plate 32 is fixed on the bevel arc plate 30, and the T-plate 32 is guided and connected to the T-slot 31. The T-slot 31 can provide a moving guide for the bevel arc plate 30 through the T-plate 32. The bevel arc plate 30 can provide support for the magnet 33. The annular groove 29 can provide a moving guide and support for the bevel arc plate 30. The positive pole of the magnet 33 faces away from the movable opening 26. The bevel wheel 17 can provide support for the magnetic ring 34. The positive pole of the magnetic ring 34 faces in the opposite direction away from the center line of the bevel wheel 17. The magnet 33 and the magnetic ring 34 are of the same polarity and repel each other. In the initial state, the magnetism of the magnet 33 and the magnetic ring 34 do not interfere with each other.

[0120] Since there are gaps between the multiple bevel arc plates 30, during the process of rotating together with the bevel rubber wheel 16, the gaps will move to a position close to the magnetic ring 34, causing the magnetic force applied to the magnetic ring 34 to temporarily disappear, thereby causing the downward pressure applied to the bevel wheel 17 to disappear. The spring 48 will use the rebound force to push the bevel wheel 17 upward through the inner plate 47. At this time, the distance moved by the bevel wheel 17 will be affected by the distance of the gaps, so that the distance the bevel wheel 17 moves upward is less than the distance the bevel wheel 17 is pushed downward by the magnet 33 and the magnetic ring 34, so that the bevel wheel 17 will not repeatedly contact the bevel rubber wheel 16 due to the gaps.

[0121] In actual application of this embodiment, when the screw rod 6 is threadedly connected to the pin, the lower end of the sleeve 18 will contact the upper end of the pin, and as the screw rod 6 is threadedly connected to the pin, the screw rod 6 will use the threaded action with the pin to drive the insertion rod 5, the longitudinal rod 4, the connecting tube 3, the T rod 2, the connecting sleeve 9, the support plate 10, the electric rod 11 and the connecting plate 12 to move downward together, so that the telescopic plate 13 shrinks and shortens under the support of the support leg 14, and at the same time, the tube 21 will be resisted by the pin and As the screw 6 and the insertion rod 5 move downward, the sleeve 18 is driven to move upward along the guide block 20 using the guide groove 19 (relative to the insertion rod 5 and the longitudinal rod 4). At the same time, the sleeve 18 will gradually push the side plate 23 and the pressure plate 24 upward as the screw 6 and the pin are threaded together under the resistance of the sleeve 21 and the pin, so that the pressure plate 24 drives the push rod 25 to move upward together, and when the screw 6 and the pin are fully threaded, the push rod 25 can contact the bottom of the push ring 27 and push the push ring upward. The push ring 27 uses an external force to drive the support rod 28 to move upward in the movable opening 26. The support rod 28 cooperates with the inclined rubber wheel 16 to provide a guide for the push ring 27, so that the push ring 27 uses the arc and external force to push the inclined arc plate 30 close to the inclined surface of the movable opening 26 during the upward movement. The inclined arc plate 30 is pushed in the direction away from the center line of the inclined rubber wheel 16 along the annular groove 29 under the action of the external force and the cooperation of the inclined surface of the movable opening 26. At the same time, the inclined rubber wheel 16 drives the magnet 33 to move together, thereby causing the magnet 33 to gradually move in the direction close to the magnetic ring 34, so that the magnet 33 uses the magnetic force and the inclined angle to push the magnetic ring 34, so that the magnetic ring 34 can use the magnetic force to drive the inclined wheel 17 downward under the guidance of the connecting tube 3, thereby causing the inclined wheel 17 to separate from the inclined rubber wheel 16, thereby realizing that after the screw 6 is threadedly connected to the pin, the driving longitudinal rod 4 and the insertion rod 5 are automatically stopped from rotating, and the driving force of the servo motor 15 is switched.

[0122] Striking parts include:

[0123] The support ring 38 is fixed to the lower end of the servo motor 15 and is located outside the driving end of the servo motor 15;

[0124] The rotary disk 39 is disposed below the support ring 38 and is rotatably connected to the support ring 38;

[0125] The V-shaped cylinder 40 is welded to the rotary disk 39 and is located outside the servo motor 15;

[0126] The rail groove 41 is provided at the upper end of the V-shaped cylinder;

[0127] The push plate 45 is disposed below the impact sleeve 8 and is guide-connected to the rail groove 41 through a connecting component.

[0128] Specifically, the servo motor 15 can provide stable support for the support ring 38, the support ring 38 can use the bearing to provide rotational support for the turntable 39, the turntable 39 can provide support for the V-shaped cylinder, and the V-shaped cylinder 40 can provide space for the rail groove 41. The inner side of the rail groove 41 is inlaid with and guided by a guide ball 44, and an impact rod 43 is welded above the guide ball 44. The impact rod 43 movably passes through the support plate 10, and the upper end of the impact rod 43 is fixedly connected to the push plate 45. The turntable 39 can use external force to drive the V-shaped cylinder to rotate, and the V-shaped cylinder 40 can use the rail groove 41 to provide moving space and guiding effect for the guide ball 44, so that the guide ball 44 can push the impact rod 43 and the push plate 45 up and down reciprocatingly during the rotation of the V-shaped cylinder 40. A through hole 42 is opened through the interior of the support plate 10, and the through hole 42 is located on the outside of the impact rod 43 and is staggered with the electric rod 11.

[0129] The screw rod 6 is screwed to the pin and the support block 36 is moved along the inner side of the groove 57 so that the support block 36 can be inserted into the inner side of the groove 57. The cylinder 40 will use the rotational power and the rail groove 41 to push the guide ball 44 to move back and forth, so that the guide ball 44 drives the impact rod 43 to push the push plate 45 up and down under the guidance of the through hole 42, so that the push plate 45 can push the impact sleeve 8 to move up and down along the guide rod 1 during the reciprocating movement. At the same time, the impact sleeve 8 will use inertia to contact the baffle plate 7 and impact the baffle plate 7 upward during this process, so that the baffle plate 7 uses the impact force to drive the guide rod 1, T rod 2, connecting sleeve 9, support plate 10, electric rod 11, connecting plate 12, longitudinal rod 4, insertion rod 5 and screw rod 6 to move upward together, so that the screw rod 6 can use the upward impact force to intermittently pull out the pin upward, and at the same time drive the telescopic plate 13 to extend, thereby realizing the function of automatic intermittent knocking to remove the pin, and adopting high-frequency and low-amplitude knocking (rather than violent hammering) to improve energy transfer efficiency and improve pin removal efficiency.

[0130] As the pin is removed, the pin provides support for the insertion rod 5 and all components above it through the screw 6, thereby promoting the extension of the telescopic plate 13 and supporting it to maintain the extended position.

[0131] As a preferred embodiment of the present invention, a circular groove 29 is formed on one side of the rotary disk 39 close to the inclined rubber wheel 16, and engaging grooves 58 are evenly distributed inside the rotary disk 39. The engaging grooves 58 are connected to the circular groove 29 and correspond to the position of the plug 37.

[0132] A sliding part is provided in the connecting tube 3, and the sliding part passes through the longitudinal rod 4 and the insertion rod 5, and is connected to the self-driving part;

[0133] The injection and sliding part includes an extrusion piece and an injection and discharge piece. The extrusion piece is elastically arranged in the connecting cylinder 3 and connected to the follower. The injection and discharge piece is arranged on the longitudinal rod 4 and the insertion rod 5 and connected to the extrusion piece.

[0134] Specifically, the rotary disk 39 can provide a space for the annular groove 29 and the fitting groove 58 , the fitting groove 58 can provide a fitting space for the plug 37 , and the annular groove 29 can provide a moving space for the plug 37 and the support block 36 .

[0135] Extrusions include:

[0136] Side openings 46 are opened on both sides of the connecting tube 3;

[0137] An inner plate 47 is fixed to the inner side of the bevel wheel 17 and passes through the side opening 46;

[0138] The spring 48 is disposed in the connecting tube 3 and is fixed to the inner plate 47 via a connecting component.

[0139] Specifically, the connecting tube 3 can provide a space for the side port 46, and the side port 46 can provide a through channel for the inner plate 47. The inner plate 47 can push the connecting tube 3 to rotate under the rotation of the inclined wheel 17, so that the connecting tube 3 can drive the one-way valve 50 and the T rod 2 to rotate together. The connecting tube 3 can provide moving space and support for the spring 48.

[0140] Note:

[0141] The bellows 49 is provided inside the spring 48 and has one end fixed to the connecting tube 3 and the other end fixed to the inner plate 47;

[0142] There are two one-way valves 50, one of which is fixed to the inner plate 47 and connected to the upper end of the bellows 49 through a pipeline, and the other is fixed to the lower end of the bellows 49, penetrates the connecting tube 3, and is fixed to the upper end of the longitudinal rod 4 through a fixing member;

[0143] The filling pipe 51 is provided through the connecting tube 3;

[0144] The solenoid valve 52 is fixed to the lower end of the filling pipe 51 and passes through the inner plate 47 and is connected to the upper end of the bellows 49;

[0145] The inclined pipe 53 is fixed to the output end of one of the one-way valves 50 and is connected to the filling pipe 51 and has an upward inclination angle;

[0146] The filling and discharging parts are arranged through the longitudinal rod 4 and the insertion rod 5 and are connected to the filling pipe 51.

[0147] Specifically, the connecting cylinder 3 can provide support for the bellows 49. The bellows 49 is made of transparent material and can provide storage space for lubricating oil. It can be squeezed, contracted and folded under the action of external force. The staff can observe the connecting cylinder 3 from the position of the side port 46 and observe the liquid level of the lubricating oil stored inside it through the connecting cylinder 3. The inner plate 47 and the connecting cylinder 3 can provide support for two one-way valves 50 respectively. The one-way valve 50 is a valve type and can provide a one-way circulation channel from top to bottom for gas and lubricating oil respectively. The filling pipe 51 can provide a flow channel for lubricating oil and air. The solenoid valve 52 can control the opening and closing of the circulation channel of the filling pipe 51, so that the lubricating oil can pass through the filling pipe 51 into the inner side of the bellows 49. One of the one-way valves 50 can provide stable support for the inclined tube 53. The upward inclination angle of the inclined tube 53 can prevent the lubricating oil from entering its inner side and can provide a circulation channel for the air in the filling pipe 51.

[0148] The injection molding parts include:

[0149] A guide hole 54 is provided through the upper ends of the longitudinal rod 4 and the insertion rod 5;

[0150] The row of holes 55 is symmetrically formed through the insertion rod 5 and is connected to the guide hole 54;

[0151] The injection hopper 56 is fixed to the upper end of the filling pipe 51.

[0152] Specifically, the guide hole 54 can provide a circulation channel for the lubricating oil, and the discharge hole 55 has an inclined angle, which can provide a discharge channel for the lubricating oil in the guide hole 54, so that the lubricating oil can be discharged between the sleeve 18 and the cylinder 21 and the screw 6, and flow to the outside of the pin for lubrication.

[0153] When the bellows 49 is filled with lubricating oil, the lubricating oil is squeezed out of the bellows 49 and the lubricating oil is squeezed out of the bellows 49. The lubricating oil can be squeezed into another one-way valve 50, and the lubricating oil passes through the one-way valve 50 into the guide hole 54. When the spring 48 rebounds due to the gap between the inclined arc plate 30 and the magnet 33, pushing the inner plate 47 and the bellows 49 to extend and reset upward, the bellows 49 will suck the air in the filling pipe 51 into the inclined tube 53 through the one-way valve 50 and the inclined tube 53, so that the air in the inclined tube 53 can be squeezed into the one-way valve 50, and the air in the one-way valve 50 can pass through the one-way valve 50 into the bellows 49, so that the bellows 49 can use the air to squeeze the lubricating oil out next time. The lubricating oil discharged into the guide hole 54 will flow downward along the guide hole 54 by gravity and vibration, and pass through the guide hole 54 into the discharge hole 55, and finally pass through the discharge hole 55, and under the resistance and guidance of the sleeve 18 and the resistance cylinder 21, it is discharged to the outside of the screw 6 and the latch, thereby achieving the effect of lubricating the latch and dissolving rust, thereby improving the efficiency and effect of pin removal.

[0154] Working principle: The distance between the legs 14 is adjusted by telescoping the electric rod 11 to adapt to different working environments. The rubber pads at the bottom of the legs 14 provide stable support, ensuring the vertical positioning of the device. The screw 6, the insertion rod 5, and the sleeve 18 are inserted into the holes where the pins are located. After the legs 14 are fixed, the connecting sleeve 9 supports the T-bar 2 to maintain verticality, providing a foundation for subsequent operations.

[0155] Start the servo motor 15, the inclined rubber wheel 16 rotates, and the friction between the inclined surface and the inclined wheel 17 drives the connecting cylinder 3, T rod 2, longitudinal rod 4, insertion rod 5 and screw 6 to rotate as a whole. The screw 6 uses the rotational power and gravity to automatically connect with the upper end of the pin through a thread. The sleeve 18 moves down with the screw 6 to contact the pin, triggering the action of the push piece. The screw 6 and the push cylinder 21 can be quickly replaced and are compatible with pins of different sizes.

[0156] After the screw 6 is fully connected, the push rod 25 moves upward, pushing the push ring 27. The bevel arc plate 30, under the action of magnetic force, drives the bevel wheel 17 downward, disengaging from the bevel rubber wheel 16 and stopping the rotation drive. The bevel rubber wheel 16 drives the rotary disk 39 to rotate through the support rod 28 and the connecting rod 35. The track groove 41 of the V-shaped cylinder 40 pushes the guide ball 44 up and down, driving the impact sleeve 8 to reciprocate along the guide rod 1 and impact the baffle plate 7. The baffle plate 7 transmits the impact force to the guide rod 1 and screw 6, achieving high-frequency, low-amplitude knocking, gradually pulling out the pin. The servo motor 15 drives the screw 6 to automatically screw in the pin without manual intervention. After the threaded connection is completed, the anti-tube 21, sleeve 18, magnet 33 and magnetic ring 34 automatically switch to knocking mode, reducing the number of operating steps.

[0157] Lubricating oil is added to the bellows 49 through the injection hopper 56, and the solenoid valve 52 controls the opening and closing of the oil circuit. When the bevel wheel 17 moves downward, the bellows 49 is squeezed, and the lubricating oil flows to the contact surface between the screw 6 and the pin through the guide hole 54 and the discharge hole 55; when the bevel wheel 17 is reset, air is sucked in to supplement the pressure to achieve continuous lubrication. The bellows 49 and the one-way valve 50 realize automatic injection of lubricating oil, which reduces friction loss, extends the service life of the device, reduces the friction of the pin, and speeds up the removal of the pin.

[0158] Through the synergy of automated drive, intelligent mode switching, high-frequency impact and self-lubricating system, efficient and low-loss pin removal is achieved, while reducing manual dependence and maintenance costs.

[0159] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
