[0077] For further understanding of the present application, the application will be described in detail with reference to the drawings. Figures 1-39The application discloses a method for using a terminal screwing tool of a patrol robot, and the terminal screwing tool comprises a fourth fixing element D1 arranged on a mechanical arm, a power mechanism D2 arranged on the fourth fixing element D1, and a driving rod assembly which is in transmission connection with an output shaft of the power mechanism D2. The driving rod assembly is in bearing connection with the fourth fixing element D1, and a screwing element D5 is arranged at the end of the driving rod assembly. The driving rod assembly comprises a driving rod D3 and a sleeve D4. The sleeve D4 is in circumferential relative fixing and axial relative sliding with the driving rod D3, and the sleeve D4 is sleeved on the driving rod D3. The cross section of the driving rod D3 is non-circular, and the sleeve D4 is provided with a sleeve hole which is matched with the shape of the driving rod D3. In specific application, the cross section of the driving rod D3 is square, regular pentagonal or triangular, or the sleeve D4 and the driving rod D3 are in key connection. An elastic buffer D32 is arranged between the driving rod D3 and the sleeve D4, and the sleeve D4 is fixedly connected with the screwing element D5. The screwing element D5 is provided with an avoiding hole D51 which is used for avoiding the driving rod D3.

[0078] A stop structure for limiting the sliding position of the sleeve D4 is arranged between the sleeve D4 and the driving rod D3. The stop structure comprises a first blocking part D41 arranged on the sleeve D4 and a second blocking part D31 arranged on the driving rod D3. When the sleeve D4 slides to a fixed position relative to the driving rod D3, the first blocking part D41 and the second blocking part D31 abut against each other to prevent the sleeve D4 from being separated from the driving rod D3. A fixed sleeve D6 is fixedly connected with the fourth fixing element D1, the fixed sleeve D6 is sleeved on the driving rod assembly, and a bearing is arranged between the driving rod assembly and the fixed sleeve D6. A stop structure for limiting the sliding position of the sleeve D4 is arranged between the sleeve D4 and the fixed sleeve D6. The stop structure comprises a first stop part D42 arranged on the sleeve D4 and a second stop part D61 arranged on the fixed sleeve D6. When the sleeve D4 slides to a fixed position relative to the driving rod D3, the first stop part D42 and the second stop part D61 abut against each other to limit the continuous movement of the sleeve D4. The movement range of the sleeve D4 is limited between the second blocking part D31 and the second stop part D61. In specific application, the first blocking part D41 and the first stop part D42 are arranged as an integrated structure.

A blocking nut is arranged at the end of the driving rod D3, and the blocking nut forms the second blocking part D31.

[0080] The fourth fixing member D1 is fixed with a fifth depth camera D7, and the fifth depth camera D7 is electrically connected with the control system. The fifth depth camera D7 is located above the driving rod D3. The fifth depth camera D7 can detect the position of the switch of the switch cabinet, and then transmit the position signal of the switch cabinet to the control system, and the control system controls the mechanical arm to make the end of the screwing tool D close to the switch of the switch cabinet. The notch D52 at the end of the screwing member D5 can engage the handle-shaped / strip-shaped switch, and then drive the driving power mechanism D2 to make the screwing member D5 screw the switch. Some switches need to be pressed after being screwed to open the switch, which requires the mechanical arm to press the screwing member D5, so that the screwing member D5 retreats relative to the driving rod D3, and the end of the driving rod D3 presses the switch. After opening the switch, the elastic release member D32 can make the screwing member D5 return to the initial position.

[0082] The driving steering mechanism 101 comprises a rolling wheel E2, a connecting frame E3, a steering driving mechanism E4 and a walking driving mechanism E5. The steering driving mechanism E4 is arranged in a fixed shell E1, and the fixed shell E1 is installed on the fixed chassis 1011.

[0083] The connecting frame E3 has a suspension mechanism, the connecting frame E3 comprises a second connecting piece E31 and a third connecting piece E32, the second connecting piece E31 and the third connecting piece E32 are slidingly connected.

[0085] An angle limiting structure is arranged between the connecting frame E3 and the fixed shell E1 to limit the rotation angle of the connecting frame E3. The angle limiting structure comprises an angle constraint E41 and a constrained part E42. The angle constraint E41 is fixedly connected with the fixed shell E1, and the constrained part E42 is directly or indirectly fixedly connected with the connecting frame E3.

The feeding part 84 is provided with a threaded hole matched with the screw rod 83, and the second motor 82 drives the screw rod 83 to rotate through a synchronous belt and a synchronous pulley. The rotation of the screw rod 83 can drive the moving base 2 to slide on the second sliding rail 81.

[0087] The rotary lifting mechanism 7 comprises a first driving part 71, a second driving part 72, a bottom nut 73, an upper nut 74 and a ball screw 75. The ball screw 75 is fixed to the moving base 2, and the bottom nut 73 and the upper nut 74 are both sleeved on the ball screw 75. The bottom nut 73 comprises a first inner ring and a first outer ring, which are connected through a bearing. The first inner ring is sleeved on the periphery of the ball screw 75, and is keyed connected with the ball screw 75. The first inner ring can only make linear motion relative to the ball screw 75, and can slide relative to the ball screw 75 in the axial direction. The first outer ring is fixedly connected with the rack assembly 1. The upper nut 74 comprises a second inner ring and a second outer ring, which are connected through a bearing. The second inner ring is provided with a thread matched with the ball screw 75, and the second outer ring is fixedly connected with the rack assembly 1. The first driving part 71 and the second driving part 72 are both mounted on the rack assembly 1. The output shaft of the first driving part 71 is synchronously belt-driven connected with the first inner ring, and the output shaft of the second driving part 72 is synchronously belt-driven connected with the second inner ring.

[0088] The bottom nut 73 and the upper nut 74 are both mounted on the rack assembly 1. The output shaft of the first driving member 71 is fixed with a synchronous pulley, the first inner ring of the bottom nut 73 is fixed with a synchronous pulley, and the synchronous pulley is externally provided with a synchronous belt. The output shaft of the second driving member 72 is fixed with a synchronous pulley, the second inner ring of the upper nut 74 is fixed with a synchronous pulley, and the synchronous pulley is externally provided with a synchronous belt. The rotating lifting mechanism 7 can realize the rotating movement, the linear movement and the linear-rotating compound movement of the rack assembly 1.

[0089] Specifically, the linear-rotating compound movement is realized by starting the first driving member 71. Since the first inner ring is fixed in the circumferential direction relative to the ball screw 75, starting the first driving member 71 will drive the rack assembly 1 to rotate around the ball screw 75, and the rotation of the rack assembly 1 will drive the second inner ring to rotate through the synchronous belt transmission between the second driving member 72 and the second inner ring, and the rotation of the second inner ring will drive the rack assembly 1 to move linearly relative to the ball screw 75.

[0090] The linear movement is realized by starting the second driving member 72. Starting the second driving member 72 will drive the second inner ring to rotate, and the rotation of the second inner ring will drive the rack assembly 1 to move linearly relative to the ball screw 75.

[0091] The rotating movement is realized by simultaneously starting the first driving member 71 and the second driving member 72. As known from the above, starting the first driving member 71 realizes the linear-rotating compound movement of the rack assembly 1. At this time, only the second driving member 72 needs to be reversed, and the rotation speed needs to be kept consistent with that of the first driving member 71, so that the second inner ring is in a stationary state, and therefore the rack assembly 1 will not move linearly, but only rotate.

[0092] The rack assembly 1 and the ball screw 75 are provided with a limiting structure for limiting the rotation angle of the rack assembly 1. The limiting structure includes a limiting member 13 and a blocking member, the limiting member 13 is fixed to the rack assembly 1, and the blocking member is directly or indirectly fixedly connected with the first inner ring / ball screw 75, the blocking member is provided with two blocking portions 761, and the limiting member 13 is limited between the two blocking portions 761. In specific applications, the blocking member is fixed to the synchronous pulley of the first inner ring.

[0093] It also includes a detection mechanism, which includes a first inductor 12 and a first inductive member 76, the first inductor 12 is fixed to the rack assembly 1, the first inductive member 76 is directly or indirectly fixedly connected with the first inner ring, and the first inductor 12 can induct the first inductive member 76. The first inductor 12 is electrically connected with the control system. In specific applications, the first inductive member 76 and the blocking member are integrally provided. The first inductive member 76 has a metal member, and the first inductive member 76 is a sensor that can induct metal. When the first inductor 12 inducts the first inductive member 76, the position of the rack assembly 1 at this time is set as the original position, and then the rotation angle of the rack assembly 1 is confirmed through the encoder of the first driving member 71.

[0098] The grommet end 51 opens the ground blade butt joint hole baffle by pressing downward. When the ground blade butt joint hole baffle enters the grommet end 51, the surface of the grommet end 51 and the ground blade butt joint hole baffle are not parallel, or the grommet end 51 and the ground blade butt joint hole baffle are slightly misaligned. After the first inclined surface 521 / second inclined surface 522 of the two adjusting pieces contacts the ground blade butt joint hole baffle, the grommet end 51 is pressed downward, and the action force between the first inclined surface 521 / second inclined surface 522 and the ground blade butt joint hole baffle makes the grommet assembly 5 slightly rotate relative to the feeding sleeve 34, so that the grommet end 51 and the ground blade butt joint hole baffle return to the parallel state, thereby facilitating the accurate butt joint of the grommet end 51 to the ground blade butt joint hole baffle of the switch cabinet.
