Detailed implementation manners

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] A special-shaped parallel groove clamp automatic installation tool suitable for live working. This automatic installation tool is used to install and fix the special-shaped parallel groove clamp 4. The special-shaped parallel groove clamp 4 includes a bottom clip 4-1, two clip seats 4-2 and two bolts 4-3. The two bottom clips 4-1 are respectively connected to the clip seats 4-2 through the bolts 4-3. By using this automatic installation tool to simultaneously tighten the bolts 4-3, and the tightening torques of the bolts 4-3 are consistent, the installation efficiency of the special-shaped parallel groove clamp 4 is improved.

[0029] The automatic installation tool includes an electric wrench 1, a fixed fixture 2, and a lead clamping mechanism 3. The fixed fixture 2 is fixedly connected to the transmission box 1-11 of the electric wrench 1. The lead clamping mechanism 3 is rotatably installed on the transmission box 1-11 of the electric wrench 1. A clamping mechanism is provided in the fixed fixture 2. The clamping mechanism is used to clamp the special-shaped parallel groove clamp 4 on the fixed fixture 2, facilitating the connection between the special-shaped parallel groove clamp 4 and this installation tool. The lead clamping mechanism 3 is rotatably connected to the fixed fixture 2, and the lead clamping mechanism 3 is adapted to the special-shaped parallel groove clamp 4 clamped on the fixed fixture 2. That is, the lead clamping mechanism 3 is arranged facing the opening of the special-shaped parallel groove clamp 4, so that the opening of the special-shaped parallel groove clamp 4 forms a closed structure, thereby fixing the automatic installation tool on the wire. By fixing the automatic installation tool on the wire, the convenience of installing the special-shaped parallel groove clamp 4 through this automatic installation tool is improved, the operation difficulty and labor intensity are reduced, and the installation efficiency of the special-shaped parallel groove clamp 4 is increased.

[0030] The fixed fixture 2 includes a clamping mechanism and a fixture bracket 2-9. The clamping mechanism is installed on the outside of the clamping bracket 2-9. The clamping bracket 2-9 is used to accommodate the special-shaped parallel groove clamp 4. When the clamping block 2-2 of the clamping mechanism extends into the clamping bracket 2-9, the clamping mechanism fixes the special-shaped parallel groove clamp 4 in the fixed fixture 2.

[0031] The clamping mechanism includes a fixture power member 2-1 and a clamping block 2-2. The middle of the clamping block 2-2 is rotatably installed on the fixture bracket 2-9 through a rotating shaft. The fixture power member 2-1 is connected to one end of the clamping block 2-2. By driving the clamping block 2-2 to swing through the fixture power member 2-1, the other side of the clamping block 2-2 extends into the clamping bracket 2-9, thereby clamping the special-shaped parallel groove clamp 4 in the fixed fixture 2.

[0032] The fixture power component 2-1 is a micro electric cylinder. A pushing block 2-4 is provided on the cylinder shaft of the fixture power component 2-1. A clamping inclined surface 2-5 and a locking plane 2-6 are provided on the pushing block 2-4. When the clamping inclined surface 2-5 abuts against the clamping block 2-2, the clamping inclined surface 2-5 drives the clamping block 2-2 to rotate, so that the clamping block 2-2 extends into the fixture bracket 2-9. As the fixture power component 2-1 continues to feed, the clamping inclined surface 2-5 separates from the clamping block 2-2, and the locking plane 2-6 abuts against the clamping block 2-2. At this time, the pushing block 2-4 moves relative to the clamping block 2-2 and will not drive the clamping block 2-2 to rotate.

[0033] As a preferred solution, the clamping block 2-2 includes a vertical portion 2-14 and a horizontal portion 2-15. The connection between the vertical portion 2-14 and the horizontal portion 2-15 is rotationally connected to the fixture bracket 2-9 through a rotating shaft. When the clamping inclined surface 2-5 abuts against the vertical portion 2-14, the clamping inclined surface 2-5 drives the clamping block 2-2 to rotate, so that the horizontal portion 2-15 extends into the fixture bracket 2-9 and abuts against the bottom clip 4-1 of the special-shaped parallel groove clamp 4. The special-shaped parallel groove clamp 4 is clamped and fixed through the bottom clip 4-1 and the wrench socket 1-14.

[0034] A self-locking gap 2-3 is provided between the side wall of the vertical portion 2-14 and the fixture bracket 2-9. When the clamping block 2-2 abuts against the clamping inclined surface 2-5, the self-locking gap 2-3 is enlarged by the clamping inclined surface 2-5, thereby driving the clamping block 2-2 to rotate. When the locking plane 2-6 abuts against the vertical portion 2-14, the locking plane 2-6 fits with the side wall of the vertical portion 2-14, so that the gap of the self-locking gap 2-3 does not change. At this time, the vertical portion 2-14 is arranged parallel to the side wall of the fixture bracket 2-9. Even if the special-shaped parallel groove clamp 4 is subjected to an outward pulling force, since the pushing block 2-4 is located in the self-locking gap 2-3, the gap size of the self-locking gap 2-3 does not change, so that the clamping block 2-2 is locked by the locking plane 2-6.

[0035] A sliding groove 2-10 is provided on the outer side of the fixture bracket 2-9. A U-shaped plate 2-11 is provided on the outer side of the sliding groove 2-10. The pushing block 2-4 is slidably installed in the sliding groove 2-10 through the square plate 2-11. Under normal conditions, the horizontal portion 2-15 of the clamping block 2-2 is located outside the fixture bracket 2-9. A reset member 2-7 is provided on the fixed fixture 2. The reset member 2-7 is connected to the vertical portion 2-14 of the clamping block 2-2. The acting force of the reset member 2-7 is directed towards the self-locking gap 2-3. When the pushing block 2-4 is located outside the self-locking gap 2-3, the reset member 2-7 reduces the gap of the self-locking gap 2-3, so that the horizontal portion 2-15 moves to the outside of the fixture bracket 2-9.

[0036] The reset member 2-7 includes a reset spring 2-12 and a top block 2-13. The top block 2-13 is fixed to the outside of the fixture bracket 2-9. The spring 2-12 is disposed between the top block 2-13 and the vertical portion 2-14, and the clamping mechanism is driven to reset by the spring 2-12.

[0037] The fixture bracket 2-9 is provided with a lead clamping arm 2-8 and a guiding portion 2-16. When the special-shaped parallel groove clamp 4 is installed in the fixed fixture 2, the guiding portion 2-16 is located on both sides of the special-shaped parallel groove clamp 4. The lead clamping mechanism 3 is rotatably connected to the lead clamping arm 2-8. The lead clamping arm 2-8 is adapted to the special-shaped parallel groove clamp 4, that is, the upper end surface of the lead clamping arm 2-8 is arc-shaped, so that the upper end surface of the lead clamping arm 2-8 is similar to the upper end surface of the bottom clip 4-1, preventing the lead clamping arm 2-8 from interfering with the electric wire.

[0038] The lead clamping mechanism 3 includes a clamping power member 3-1 and a clamping connecting rod 3-2. The clamping connecting rods 3-2 are respectively rotatably installed on the two lead clamping arms 2-8 of the fixture bracket 2-9 through rotating shafts. The clamping connecting rods 3-2 are connected by a connecting rod 3-4. The clamping power member 3-1 is connected to the connecting rod 3-4, and the clamping power member 3-1 is rotatably installed on the transmission box 1-11 through a connecting seat. The clamping power member 3-1 is a micro electric cylinder. The connecting rod 3-4 is driven to move by the clamping power member 3-1, so as to drive the clamping connecting rod 3-2 to swing relative to the lead clamping arm 2-8. A clamping portion 3-3 is provided on the clamping connecting rod 3-2. The clamping portion 3-3 is arranged with an opening facing the special-shaped parallel groove clamp 4. When the cylinder shaft of the clamping power member 3-1 extends, the opening of the clamping portion 3-3 facing the special-shaped parallel groove clamp 4 is closed, so as to fix the automatic installation tool on the electric wire, facilitating the automatic installation tool to tighten the bolt 4-3.

[0039] The electric wrench includes a power assembly 1-1 and at least two output members 1-2. A torque clutch assembly 1-3 is provided on the output member 1-2. The torque clutch assembly 1-3 is used to control the torque output by the output member 1-2 to ensure that the torques output by multiple output members 1-2 are consistent. The multiple output members 1-2 are respectively connected to the power assembly 1-1 through the torque clutch assembly 1-3. The multiple output members 1-2 are driven to rotate simultaneously by the power assembly 1-1. Driving the multiple output members 1-2 to rotate by a single power assembly 1-1 facilitates the simultaneous locking operation of multiple bolts and improves the working efficiency of locking multiple bolts. And through the setting of the torque clutch assembly 1-3, the locking torques of the multiple output members 1-2 on the bolts are consistent, ensuring the consistency difference of the locking torques of the multiple bolts.

[0040] A transmission case 1-11 is provided on the powertrain 1-1. An active gear 1-12 and a transmission gear 1-13 are provided in the transmission case 1-11. The output member 1-2 is rotatably installed in the transmission case 1-11, and the end of the output member 1-2 extends out of the transmission case 1-11. The active gear 1-12 is connected to the powertrain 1-1. The torque clutch assembly 1-3 is connected to the active gear 1-12 through the transmission gear 1-13. The power of the powertrain 1-1 is sequentially transmitted to the output member 1-2 through the active gear 1-12, the transmission gear 1-13, and the torque clutch assembly 1-3. When the locking torque of the output member 1-2 reaches the preset value, the torque transmission member 1-4 and the power connection member 1-5 of the torque clutch assembly 1-3 are separated, thereby blocking the torque transmission.

[0041] In this embodiment, two output members 1-2 are provided in the transmission case 1-11. The torque clutch assemblies 1-3 on the two output members 1-2 are respectively connected to the transmission gear 1-13. The active gear 1-12 is sleeved on the output shaft of the powertrain 1-1. A connecting shaft 1-12-1 is provided on the top of the active gear 1-12. The connecting shaft 1-12-1 is connected to the top of the transmission case 1-11 through a bearing. The transmission gear 1-13 is installed in the transmission case 1-11 through a transmission shaft 1-13-1-1. The two ends of the transmission shaft 1-13-1-1 are respectively connected to the top surface and the bottom surface of the transmission case 1-11.

[0042] An operating rod 1-15 is provided on the outside of the transmission case 1-11. The operating rod 1-15 is made of insulating material. The operator holds this electric wrench through the operating rod 1-15 to prevent the operator from directly contacting the electric wrench and ensure the personal safety of the operator.

[0043] In this embodiment, the output member 1-2 is a rotating shaft. The bottom and middle of the output member 1-2 are rotatably connected to the transmission case 1-11 through bearings. The top of the output member 1-2 extends out of the transmission case 1-11. The top of the output member 1-2 extends into the fixed fixture 2. A wrench socket 1-14 is detachably installed on the top of the output member 1-2. The output member 1-2 is connected to the bolt through the wrench socket 1-14 to rotate and lock the bolt of the special-shaped parallel groove clamp arranged in the fixed fixture 2.

[0044] The torque clutch assembly 1-3 includes a torque transmission member 1-4 and a power connection member 1-5. The power connection member 1-5 is connected to the transmission gear 1-13, facilitating the transmission of the torque of the power assembly 1-1 to the power connection member 1-5. The torque transmission member 1-4 is slidably connected to the output member 1-2. The torque transmission member 1-4 and the power connection member 1-5 are adapted, that is, the torque transmission member 1-4 and the power connection member 1-5 are connected in a clutch manner. The clutch connection includes two connection states: (1) The torque transmission member 1-4 and the power connection member 1-5 are engaged with each other, facilitating the transmission of the torque of the power assembly 1-1 to the output member 1-2; (2) The torque transmission member 1-4 and the power connection member 1-5 are separated from each other. At this time, the torque of the power assembly 1-1 cannot be transmitted to the output member 1-2. When the bolts are tightened to a certain tightening force, the torque transmission member 1-4 and the power connection member 1-5 are separated, thereby achieving the tightening of multiple bolts under the same tightening torque.

[0045] An external gear is provided on the outer side of the power connection member 1-5. The external gear meshes with the transmission gear 1-13, facilitating the driving of the power connection member 1-5 to rotate by the transmission gear 1-13. The middle part of the power connection member 1-5 is a circular shaft hole. The power connection member 1-5 is sleeved on the output member 1-2, enabling the power connection member 1-5 to rotate and slide relative to the output member 1-2.

[0046] Ratchet teeth 1-6 are provided on the upper end face of the torque transmission member 1-4. Similarly, ratchet teeth 1-6 are also provided on the lower end face of the power connection member 1-5. By controlling the engagement and disengagement of the ratchet teeth 1-6 of the torque transmission member 1-4 and the power connection member 1-5, the on-off of the torque transmission between the power assembly 1-1 and the output member 1-2 is controlled. When the ratchet teeth 1-6 on the torque transmission member 1-4 and the power connection member 1-5 are engaged, the torque transmission member 1-4 and the power connection member 1-5 rotate simultaneously, enabling the torque of the power assembly 1-1 to be transmitted to the output member 1-2. When the rotational torque reaches a certain preset tightening value, the ratchet teeth 1-6 on the torque transmission member 1-4 and the power connection member 1-5 are separated, thereby cutting off the torque transmission.

[0047] The torque transmission member 1-4 is a cylinder and is sleeved on the output member 1-2. A connecting shaft 1-9 is assembled on the output member 1-2. The connecting shaft 1-9 is fixed relative to the output member 1-2. A waist-shaped chute 1-8 is provided on the torque transmission member 1-4. Both ends of the output member 1-2 are inserted into the waist-shaped chute 1-8, enabling the torque transmission member 1-4 to axially move relative to the output member 1-2. An elastic member 1-7 is provided on the output member 1-2. Preferably, the elastic member 1-7 is a spring. By the elastic member 1-7 abutting against the torque transmission member 1-4, the ratchet teeth 1-6 on the torque transmission member 1-4 and the power connection member 1-5 are engaged with each other under normal conditions, facilitating the transmission of the torque of the power assembly 1-1 to the output member 1-2.

[0048] A plain bearing 10 is provided on the output member 2, and a limit ring 2-1 is provided on the output member 2. The plain bearing 10 is arranged between the limit ring 2-1 and the power connecting member 5 to prevent sliding friction between the power connecting member 5 and the output member 2 and improve the service life of the power connecting member 5 and the output member 2.

[0049] The working principle of this automatic installation tool is as follows. (1) Place the special-shaped parallel groove clamp 4 in the fixed fixture 2. The fixture power member 2-1 drives the push block 2-4 to move, and the push block 2-4 drives the clamping block 2-2 to swing, so that the transverse portion 2-15 of the clamping block 2-2 extends into the fixture bracket 2-9, and the bottom clip 4-1 is fixedly clamped in the fixed fixture 2 through the transverse portion 2-15 and the wrench socket 1-14. (2) Clamp the two wires into the wire groove formed between the bottom clip 4-1 and the clip seat 4-2 respectively. (3) The clamping power member 3-1 works, driving the clamping connecting rod 3-2 to swing, so that the clamping portion 3-3 closes the opening of the wire groove formed between the bottom clip 4-1 and the clip seat 4-2, and thus fixes this automatic installation tool on the wire. (4) Drive the electric wrench to work, and lock the bolt 4-3 at the same torque through the torque clutch assembly 1-3. (5) The clamping power member 3-1 resets. (6) The fixture power member 2-1 resets, the clamping block 2-2 separates from the bottom clip 4-1, and this automatic installation tool can separate from the special-shaped parallel groove clamp 4 under the action of its own weight.
