Description

Technical Field

[0001] The invention relates to the technical field of electric power, in particular to a ignition connection device. Background Art

[0002] Live connection of the distribution network is one of the main operations in live operation, which requires connecting one end of the high-voltage drainage line to the high-voltage busbar.

[0003] High-voltage drain wire is a common power system equipment, and its main function is to shunt or guide extra current to prevent other components from being damaged by overload or arcing. Due to its good insulation and protection, the drain wire can also carry and isolate current to ensure the safe operation of other power equipment. In the voltage distribution devices of power plants and substations at all levels, the busbar is a conductor that connects large electrical equipment such as generators and transformers with various electrical devices to build a bridge. It has the functions of collecting, transmitting and distributing electrical energy. The bridge role played by the busbar is the basis for the normal operation of the power system.

[0004] In the live connection operation of the distribution network, one end of the drainage wire at the secondary support of the high-voltage power pole needs to be stripped and connected to the stripped busbar at a higher place, while the other end of the drainage wire, i.e. the root, remains fixed at the secondary support. After the drainage wire is connected to the busbar, the live wire clamp fixes the two together to achieve conduction between the drainage wire and the busbar.

[0005] The parallel groove wire clamp is one of the commonly used live wire clamps, which has the advantages of corrosion resistance, earthquake resistance, convenience, and high efficiency. Manual installation of the parallel groove wire clamp has a high risk factor, and the torque applied to the bolt varies from person to person, resulting in poor consistency in the pressure of the wire clamp on the wire. The pressure between the wire clamp and the wire is too large, and the creep of the wire is too large; the pressure between the wire clamp and the wire is too small, and the wire clamp and the wire are not pressed tightly enough. Using a live wire connection device to install the wire clamp has a high safety factor and better guarantees the installation quality. The replacement of manual operation with a live wire connection device is an inevitable development trend for high-voltage live wire connection operations.

It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0051] In addition, the accompanying drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted.

[0052] Figure 1 and Figure 2 A three-dimensional diagram showing a fire connection device provided by an embodiment of the present disclosure, Figure 3 exhibit Figure 2 A cross-sectional view along the first direction AA', combined with Figure 1-Figure 3 As shown, the ignition device includes:

[0053] A base 10 is provided with a wire clamp assembly position S1 and at least two bolt installation positions S2 arranged at the bottom of the wire clamp assembly position S1;

[0054] The limiting assembly 20 comprises a limiting tongue 21 provided at a corresponding side of the wire clamp assembly position S1 and a first driving mechanism connected to the limiting tongue 21 in a transmission manner, wherein the first driving mechanism is configured to control and drive the limiting tongue 21 to extend and retract laterally relative to the wire clamp assembly position S1;

[0055] A screwing assembly 30 is provided at each bolt installation position S2. Figure 4 As shown, each screwing assembly 30 includes a bolt sleeve 31 , a first spring 32 , a screwing transmission mechanism 33 and a second driving mechanism 34 .

[0056] like Figure 4 As shown, the bolt sleeve 31 has a sleeve head 311 and a rod 312 located at the bottom of the sleeve head 311. The sleeve head 311 is oriented toward the wire clamp assembly position S1 along the axial direction HH'. The first spring 32 is fitted with the rod 312 and abuts between the bolt sleeve 31 and the first support structure 11 fixed relative to the bolt sleeve 31 along the axial direction HH'. The first support structure 11 can be fixed in the base 10.

[0057] The screwing transmission mechanism 33 is coupled between the second driving mechanism 34 and the bolt sleeve 31. The second driving mechanism 34 is configured to output controlled rotational motion. The screwing transmission mechanism 33 is configured to transmit rotational motion to the bolt sleeve 31 and block the translational motion of the bolt sleeve 31 along the axial direction HH' from being transmitted to the second driving mechanism 34.

[0058] When using the fire connection device of this embodiment, the wire clamp 40 is first placed in the wire clamp assembly position S1, and the upper and lower wire clamp parts 41 and 42 of the wire clamp 40 are pre-tightened by bolts 50. Figure 3 Each of the wire clamp assembly positions S1 includes two bolt installation positions S2 arranged along the first direction AA', and each bolt installation position S2 is pre-tightened with a corresponding bolt 50. Figure 4 As shown, the bolt 50 is threadedly matched with the upper wire clamp portion 41, and the bolt head is placed in the sleeve head 311 and matches the sleeve groove shape of the sleeve head 311;

[0059] Next, the first driving mechanism is controlled to drive the limiting tongue 21 to extend to press the lower wire clamp 42 along the axial direction HH', and the lower wire clamp 42 is axially limited to stabilize it on the base 10. At the same time, the first spring 32 is also compressed to be in a squeezed state;

[0060] Afterwards, the mechanical arm is operated to install the above-mentioned fire connection device, and the fire connection device is transferred to the cable 1 position, so that the cable 1 is placed in the cable 1 clamping space between the upper and lower clamping parts 41 and 42; then, the fire connection device is transferred to the cable 2 position, so that the cable 2 is placed in the cable 2 clamping space between the upper and lower clamping parts 41 and 42; wherein the cable 1 clamping space and the cable 2 clamping space are located on both sides of the bolt 50. Next, the second driving mechanism 34 is controlled to output a rotational motion, and finally the bolt sleeve 31 is driven to rotate.

[0061] like Figure 4 As shown, the bolt sleeve 31 drives the bolt 50 to rotate. Since the two bolts 50 form a rotation limit for the upper wire clamp 41, the upper wire clamp 41 does not rotate synchronously with the bolt 50, so that the bolt 50 moves upward along the axial direction HH' while rotating. When the bolt 50 moves upward, the first spring 32 releases the elastic force, pushing the bolt sleeve 31 to move upward with the bolt 50 to prevent the bolt sleeve 31 from separating from the bolt head. In this process, the limiting tongue 21 maintains the axial limit on the lower wire clamp 42. If the bolt head moves upward to abut the lower wire clamp 42, the lower wire clamp 42 is axially limited by the limiting tongue 21, and the bolt 50 is blocked and cannot continue to move upward. Therefore, the upward trend of the bolt 50 is converted into the downward trend of the upper wire clamp 41, until the upper and lower wire clamps 41, 42 are gradually retracted to the clamping position to clamp the cable 1 and the cable 2, such as the drainage line and the busbar.

[0062] After the wire clamp 40 is assembled in place, the second driving mechanism 34 is controlled to stop working, and the first driving mechanism is controlled to drive the limit tongue 21 to retract, and the axial limit of the wire clamp 40 is released. At this time, the mechanical arm is controlled to transfer the fire connection device, and the fire connection device is separated from the wire clamp 40, thereby completing the overlap of the cable 1 and the cable 2.

[0063] In this embodiment, the wire clamp 40 is a universal parallel groove wire clamp. The upper wire clamp portion 41 of the wire clamp 40 has a first through hole, the inner wall of which is threaded and is threadedly connected to the bolt 50. The lower wire clamp portion 42 has a second through hole, the inner wall of which is not threaded, and the size of the second through hole is larger than the first through hole, so that the lower wire clamp portion 42 is only sleeved on the bolt 50 and is not threadedly connected to the bolt 50. When the bolt 50 is screwed, the upper wire clamp portion 41 moves relative to the bolt 50 to approach the lower wire clamp portion 42, thereby clamping the cable 1 and the cable 2.

[0064] The second through hole is in the shape of a long strip, with the length direction along the second direction BB' and the width direction along the first direction AA'. The difference in wire diameter between the busbar and the drain wire may be too large or too small. The length and width directions of the second through hole are designed in this way to leave enough margin to adapt to busbars and drain wires of different wire diameters.

[0065] In this embodiment, the limiting tongue 21 is used to press the lower wire clamp 42 along the axial direction HH', which can reduce the shaking of the lower wire clamp 42 and prevent the shaking of the lower wire clamp 42 from affecting the smooth entry of the busbar or the drainage line into the corresponding clamping space in the wire clamp 40 during the transfer of the ignition device.

[0066] In one application scenario, combined with Figure 2 As shown, each wire clamp assembly position S1 includes a drain line side wire clamp position S11 and a bus line side wire clamp position S12 located on both sides of the bolt installation position S2 along the second direction BB'. When the wire clamp 40 is pre-tightened and installed on the ignition connection device, a drain line side wire clamping space 4a and a bus line side wire clamping space 4b are formed between the upper and lower wire clamping parts 41 and 42 of the wire clamp 40. Along the axial direction HH' parallel to the bolt sleeve 31, the drain line side wire clamping space 4a corresponds to the drain line side wire clamp position S11, and the bus line side wire clamping space 4b corresponds to the bus line side wire clamp position S12.

[0067] In this way, when the fire is connected, Figure 2 and Figure 5 As shown, the robot arm is first operated to transfer the fire connection device carrying the pre-installed wire clamp 40 to the position of the drainage line 100, and the drainage line 100 is inserted into the clamping space 4a on the drainage line side, and then the fire connection device is transferred to the position of the busbar 200, so that the busbar 200 enters the clamping space 4b on the busbar side. Finally, the corresponding second driving mechanism 34 is controlled to drive the screwing assembly 30 to tighten the bolts 50 on both sides.

[0068] The fire connection device of this embodiment can automatically complete the live fire connection operation, which not only improves the operation efficiency, but also improves the operation safety.

[0069] The fire connection device of this embodiment can be used in conjunction with a boom truck. For example, the fire connection device with a pre-tightening wire clamp is pre-installed on the boom truck, and the mechanical arm on the boom truck is controlled to grab the fire connection device and move it to the positions of the drain line 100 and the busbar 200 in sequence, so that the drain line 100 and the busbar 200 enter the drain line side clamping space 4a and the busbar side clamping space 4b respectively, and further tighten the wire clamp 40 to overlap the busbar 200 and the drain line 100. The fire connection device of this embodiment can improve the automation degree of power operations, and improve the safety and efficiency of live operations.

[0070] In the embodiments of the present disclosure, Figure 2 As shown, a pair of wire clamp assembly positions S1 are provided on the base 10, and two wire clamps 40 can be installed at the same time, so that the busbar 200 and the drain wire 100 (such as Figure 5 As shown) can be connected by a pair of wire clamps 40, and the live wire connection is more secure.

[0071] In the embodiments of the present disclosure, Figure 3 As shown, the screwing assembly 30 and the limiting assembly 20 are both integrated in the base 10. The use of the fire connection device can realize the automated operation of the wire clamp assembly, greatly reduce manual operations, and improve work efficiency.

[0072] In the embodiments of the present disclosure, Figure 4 As shown, in the screwing assembly 30, the screwing transmission mechanism 33 includes:

[0073] A sleeve 330 and a first transmission shaft 331 extending along the axial direction HH';

[0074] A first rotation transmission connection is provided between the sleeve 330 and the second driving mechanism 34 to input a rotational motion;

[0075] The two ends of the first transmission shaft 331 are respectively arranged with the sleeve 330 and the bolt sleeve 31 to form a second rotation transmission connection. The first transmission shaft 331 and at least one of the sleeve 330 and the bolt sleeve 31 are also arranged to be slidably matched along the axial direction HH′.

[0076] In the embodiment of the present disclosure, the first rotation transmission connection allows the sleeve 330 to rotate under the drive of the second drive mechanism 34. The second rotation transmission connection allows the sleeve 330 to drive the first transmission shaft 331 to rotate synchronously, further driving the bolt sleeve 31 to rotate, and realizing the screwing of the bolt 50. At the same time, the bolt sleeve 31 follows the bolt 50 upward during rotation, and the sliding fit makes the first transmission shaft 331 not block the upward movement of the bolt sleeve 31, thereby improving the screwing feasibility and reliability.

[0077] In one embodiment, when the first transmission shaft 331 is fixedly installed with the rod 312 of the bolt sleeve 31, the sliding fit causes the first transmission shaft 331 to move upward synchronously with the bolt sleeve 31. In another embodiment, when the first transmission shaft maintains the sliding fit with the rod, the first transmission shaft may not move upward accordingly.

[0078] Therefore, the first transmission shaft 331 cooperates with the sleeve 330 to transmit rotational motion and block the translational motion of the bolt sleeve 31 along the axial direction HH' from being transmitted to the second driving mechanism 34, so that the upward movement of the bolt sleeve 31 will not be blocked, and the bolt 50 can be screwed while maintaining upward movement under the elastic force of the first spring 32.

[0079] In the embodiments of the present disclosure, Figure 4 As shown, a first accommodating space 3a is provided in the rod portion 312, the first axial end of the first transmission shaft 331 is sleeved in the first accommodating space 3a and fixedly installed with the bolt sleeve 31, the first spring 32 is encapsulated in the first accommodating space 3a and sleeved outside the first transmission shaft 331, and the second axial end of the first transmission shaft 331 and the sleeve 330 are set as a second rotational transmission connection and sliding fit.

[0080] In this embodiment, the first spring 32 is also located in the first accommodating space 3a, and at this time, the two ends of the first spring 32 respectively abut against the top wall of the first accommodating space 3a and the first supporting structure 11 below, wherein the first spring 32 does not directly abut against the first supporting structure 11, but abuts against the first supporting structure 11 through the intermediate lining structure 5. The first accommodating space 3a encapsulates the first spring 32, and prevents the first spring 32 from shaking when in action through radial limiting, thereby improving product integration and operation reliability.

[0081] In another embodiment, the first spring may be sleeved outside the rod portion and abut against the axial direction HH' of the sleeve head. Therefore, the design may be performed according to the specific installation environment.

[0082] In an optional embodiment, a third through hole that penetrates the first accommodating space 3a is provided in the sleeve head 311 of the bolt sleeve 31, and a threaded hole is provided at the first axial end of the first transmission shaft 331. A screw 35 is passed through the third through hole and threadedly engaged with the threaded hole, and the screw 35 fixes the bolt sleeve 31 and the first transmission shaft 331.

[0083] In an optional implementation, an interference fit may be provided between the first shaft end of the first transmission shaft and the first accommodating space to achieve fixed fitting.

[0084] In an alternative manner, a first accommodating space is provided at the first axial end of the first transmission shaft, and the rod portion of the bolt sleeve is inserted into the first accommodating space and fixedly connected.

[0085] The first transmission shaft and the bolt sleeve adopt a split assembly design, which can reduce the complexity of product manufacturing. The split design also makes the corresponding components small in size, and the assembly operation can be realized in the limited space of the base.

[0086] In the embodiment of the present disclosure, a magnet 60 is provided in the sleeve groove in the sleeve head 311, and the magnet 60 magnetically attracts the bolt 50 to be screwed, so as to stabilize the bolt 50. In this way, when the bolt 50 is tightened so that the wire clamp 40 clamps the busbar 200 and the drain wire 100 (such as Figure 5 As shown), the bolt 50 and the bolt sleeve 31 move upward synchronously with good stability.

[0087] In this embodiment, if Figure 4 As shown, the second rotation transmission connection and sliding fit are configured as follows:

[0088] The second shaft end of the first transmission shaft 331 is sleeved in the shaft sleeve 330 , and the outer circumferential surface of the second shaft end cooperates with the inner circumferential surface of the shaft sleeve 330 to form a second rotation transmission connection and a sliding fit.

[0089] In one embodiment, the outer circumferential cross section of the second axial end of the first transmission shaft 331 and the inner circumferential cross section of the sleeve 330 are both waist-shaped holes, and the shapes of the two are matched. On the one hand, the waist-shaped hole shape forms a relative rotation limit between the first transmission shaft 331 and the sleeve 330 to achieve synchronous rotation, and on the other hand, this shape matching will not block the relative axial HH' movement between the first transmission shaft 331 and the sleeve 330.

[0090] The waist-shaped hole is an example, and the second rotation transmission connection and sliding fit can be achieved by setting other shapes between the two.

[0091] In an optional manner, the second shaft end is sleeved in the shaft sleeve, a first groove and a radial projection slidably matched with the first groove are provided between the second shaft end and the shaft sleeve, and the first groove extends along an axial direction parallel to the axial direction HH'. When the first transmission shaft moves upward, the radial projection slides in the first groove along the axial direction HH'.

[0092] In the embodiments of the present disclosure, Figure 6 As shown, the screw transmission mechanism 33 also includes:

[0093] The second transmission shaft 332 is fixedly mounted with the first transmission shaft 331 along the axial direction HH′;

[0094] The second transmission shaft 332 extends into the inner space 3b of the sleeve 330. The second transmission shaft 332 is provided with a first radial outer protrusion 3320. The sleeve 330 is provided with a radial inner protrusion 3300. Along the axial direction HH', the radial inner protrusion 3300 is located between the first radial outer protrusion 3320 and the first transmission shaft 331.

[0095] In this embodiment, the first radial outer protrusion 3320 cooperates with the radial inner protrusion 3300 to limit the upward movement position of the bolt sleeve 31. When the bolt 50 is screwed, the second transmission shaft 332 moves upward with the bolt sleeve 31. When the first radial outer protrusion 3320 moves upward to abut against the radial inner protrusion 3300, the bolt sleeve 31 stops moving upward. This position can also be used to detect the limit position of the tightening of the bolt 50, and immediately trigger the second drive mechanism 34 to shut down.

[0096] In this embodiment, the second transmission shaft 332 is fixedly mounted on the first transmission shaft 331, for example, by interference fit, or by screw connection. There may be no contact between the second transmission shaft 332 and the sleeve 330 in the radial direction.

[0097] In the embodiments of the present disclosure, Figure 4 and Figure 6 As shown, the screwing transmission mechanism 33 further includes: a third transmission shaft 333 , a second spring 334 and a screwing limiting mechanism 335 .

[0098] like Figure 6 As shown, the third transmission shaft 333 is located on the side of the sleeve 330 away from the bolt sleeve 31, and the sleeve 330 is set as a first rotation transmission connection with the second driving mechanism 34 through the third transmission shaft 333. The sleeve 330 has a second radial outer protrusion 3301, and the end face of the third transmission shaft 333 facing the second radial outer protrusion 3301 along the axial direction HH' is provided with a plurality of radially distributed ridges 3330, and the second radial outer protrusion 3301 is provided with a plurality of circumferentially distributed through holes 32a, and the through holes 32a and the ridges 3330 are alternately arranged in the circumferential direction.

[0099] The second spring 334 is sleeved on the outside of the shaft sleeve 330 , and abuts against the first supporting structure 11 and the second radial outer protrusion 3301 .

[0100] The screwing limit mechanism 335 includes a pin structure 3350 slidably encapsulated in the through hole 32a, and a top pressing structure 3351 located between the second radial outer protrusion 3301 and the second spring 334 and at least covering the through hole 32a. The pin structure 3350 is provided with a spherical portion 33501 extending out of the through hole 32a toward the third transmission shaft 333.

[0101] In the initial state, the second spring 334 is in a compressed state, and applies pressure to the second radial outer protrusion 3301, so that the sleeve 330 is closely abutted against the convex strip 3330 on the third transmission shaft 333. During operation, the second driving mechanism 34 is controlled to drive the third transmission shaft 333 to rotate, and the spherical portion 33501 of the pin structure 3350 abuts against the side of the corresponding convex strip 3330. At this time, the second spring 334 applies pressure to the pin structure 3350 through the top pressing structure 3351, so that a rotation limit is formed between the pin structure 3350 and the corresponding convex strip 3330, driving the sleeve 330 to rotate synchronously.

[0102] Combination Figure 4 and Figure 6 As shown, when the wire clamp 40 has clamped the busbar 200 and the drain wire 100 (as shown in FIG. Figure 5 As shown in the figure, when it is impossible to close further, since the bolt 50 has been completely tightened, the rotation of the bolt sleeve 31 is restricted, the sleeve 330 stops rotating instantly, while the third transmission shaft 333 continues to rotate, and the spherical portion 33501 of the pin structure 3350 is subjected to a relatively large circumferential extrusion force from the side of the corresponding convex strip 3330, which is further converted into a reverse force on the second spring 334 through the pin structure 3350 and the pressure-top structure 3351. In this process, the pin structure 3350 overcomes the pressure of the second spring 334 to squeeze the second spring 334 to contract, so that the pin structure 3350 pushes the pressure-top structure 3351 outward, and the spherical portion 33501 rolls along the side of the corresponding convex strip 3330 toward the top of the convex strip 3330, and then rolls down from the top of the convex strip 3330 along the side toward the bottom of the convex strip 3330, and the pin structure 3350 retracts into the through hole 32a.

[0103] When the spherical portion 33501 is located at the top of the convex strip 3330, the spherical portion 33501 plays the role of separating the shaft sleeve 330 from the convex strip 3330, resulting in the rotational motion output by the third transmission shaft 333 being unable to be transmitted to the bolt sleeve 31, until the third transmission shaft 333 is further rotated to the position where the corresponding convex strip 3330 passes over the through hole 32a, the second spring 334 releases the elastic force, the pin structure 3350 retracts into the through hole 32a, and the spherical portion 33501 is ejected again and abuts against the side of the corresponding convex strip 3330. However, this time period is very short and can be ignored. Then, the pin structure 3350 pushes the top structure 3351 outward again, and the spherical portion 33501 rolls toward the top of the convex strip 3330 again, blocking the rotational motion output by the third transmission shaft 333 from being transmitted to the bolt sleeve 31, and then rolls toward the bottom of the convex strip 3330 relative to the convex strip 3330, and repeats the above steps.

[0104] In this way, after the bolt 50 has been tightened, on the one hand, the spherical portion 33501 blocks the transmission of the rotational motion output by the third transmission shaft 333 to the sleeve 330, and the bolt sleeve 31 stops further screwing the bolt 50, which helps to protect the bolt 50 and the wire clamp 40. On the other hand, the sleeve 330 is blocked from rotating, while the third transmission shaft 333 is still rotating. At this time, the spherical portion 33501 retracts to offset the reverse torque generated by the sleeve 330 on the second drive mechanism 34 through the third transmission shaft 333 due to the blocked rotation, thereby preventing the second drive mechanism 34 from being blocked and damaged.

[0105] In the embodiments of the present disclosure, Figure 6 As shown, the pin structure 3350 includes: a pin 33502 and a ball, and a spherical portion 33501 is formed on the ball. In the initial state, there may be a gap or no gap between the ball and the pin 33502.

[0106] In an optional embodiment, the pin structure may also be a round-head cylindrical pin, and the spherical portion is formed on the round head of the round-head cylindrical pin.

[0107] In the embodiment of the present disclosure, the pin structure 3350 and the top pressing structure 3351 can be a separate structure or an integrated structure, which is not limited here.

[0108] The top pressing structure 3351 is configured as a ring surrounding the shaft sleeve 330, or configured as a cap-shaped structure installed with the pin structure 3350, for example, the top pressing structure 3351 and the column pin 33502 are formed as a cylindrical pin as an integral structure.

[0109] In the embodiment of the present disclosure, in the initial state, the third transmission shaft 333 may or may not abut against the second radially outer protrusion 3301 of the sleeve 330 in the axial direction HH' through the convex strip 3330. When the convex strip 3330 does not abut against the second radially outer protrusion 3301, the spherical portion 33501 of the pin structure 3350 may abut against the third transmission shaft 333 under the action of the second spring 334. Therefore, the height of the convex strip 3330 matches the spherical portion 33501 of the pin structure 3350 to achieve rotational limiting.

[0110] In the embodiments of the present disclosure, Figure 4 and Figure 6 As shown, the bolt installation position S2 in the base 10 is provided with a first sub-channel T1 and a second sub-channel T2 separated by the first support structure 11, the bolt sleeve 31 and the first spring 32 are encapsulated in the first sub-channel T1, the sleeve 330 is encapsulated in the second sub-channel T2, and the first transmission shaft 331 passes through the first sub-channel T1 and the second sub-channel T2 at the same time. In this embodiment, the screwing assembly 30 is encapsulated by the first sub-channel T1 and the second sub-channel T2, thereby improving the product integration and reliability.

[0111] like Figure 4 As shown, the second driving mechanism 34 may include:

[0112] A second rotating motor 340 having a second motor output terminal 34a;

[0113] The second transmission mechanism 341 has a second rotation input end 34b and second rotation output ends 34c respectively matched with different third transmission shafts 333 of the same wire clamp assembly position S1, the second rotation input end 34b is transmission-connected with the second motor output end 34a to input rotational motion, and each second rotation output end 34c is transmission-connected with the matched third transmission shaft 333 to drive different third transmission shafts 333 to rotate synchronously;

[0114] The second transmission mechanism 341 is configured to convert the rotational movement of the second rotational input end 34b into a synchronous rotation of a different second rotational output end 34c.

[0115] In this embodiment, Figure 4 As shown, the second transmission mechanism 341 is a gear transmission mechanism. Figure 3 As shown, two third transmission shafts 333 are provided corresponding to the two bolt installation positions S2 of the same wire clamp assembly position S1, and a transmission shaft gear 36 is mounted on each third transmission shaft 333, and the second rotation output end 34c is formed on the transmission shaft gear 36. A second motor gear 342 is mounted on the second motor output end 34a of the second rotary motor 340, and the second rotation input end 34b is formed on the second motor gear 342. The second motor gear 342 is meshed with the two transmission shaft gears 36 at the same time to form a gear transmission mechanism (i.e. corresponding to the second transmission mechanism 341). In this way, under the drive of the same second rotary motor 340, the two transmission shaft gears 36 can maintain synchronous rotation, keep the same rotation direction, and realize synchronous screwing.

[0116] By using this embodiment, a single rotating motor and a gear transmission mechanism are used to match the design, which can save components and enhance product integration. In addition, two bolts of the same wire clamp are screwed synchronously, and the screwing control is easy to achieve with high control accuracy.

[0117] In another embodiment, a transmission gear may be designed between the transmission shaft gear and the second motor gear to achieve synchronous rotation of the two first gears.

[0118] In an optional manner, a belt transmission mechanism may be used instead of a gear transmission mechanism. For example, a driving wheel and a driven wheel are respectively mounted on two third transmission shafts at the same wire clamp assembly position, and the driving wheel is transmission-connected to the output end of the second motor, and the transmission connection may be a belt transmission, a coaxial connection or a gear transmission.

[0119] In an optional manner, each third transmission shaft may be equipped with a rotary motor for rotational drive. Then, during operation, it is considered to synchronously control the two rotary motors to output synchronous rotational motion.

[0120] As shown above, the second transmission mechanism can be a gear transmission mechanism or a belt transmission mechanism. Taking the gear transmission mechanism as an example, the second rotation input end is formed on the second motor gear, and the second rotation output end is formed on the transmission shaft gear.

[0121] In the embodiments of the present disclosure, Figure 3 As shown, the diversion line 100 (see Figure 5 ) and busbar 200 (see Figure 5 ) and during the process of inserting the wire and screwing the bolt, the limiting tongue 21 is used to press the wire clamp 40. Among them, at each wire clamp assembly position S1, the limiting assembly 20 includes a pair of limiting tongues 21, which are respectively located on both sides of the wire clamp assembly position S1 along the first direction AA', for example, they can be symmetrically distributed. In this way, the wire clamp 40 at the same wire clamp assembly position S1 can use a pair of limiting tongues 21 for axial HH' limiting, which can enhance the stability of the wire clamp 40 during the movement of the ignition device and the installation of the wire clamp, and improve the feasibility of automatic installation of the wire clamp 40.

[0122] In the embodiments of the present disclosure, Figure 2 As shown, the wire clamp assembly position S1 has a drainage line side wire clamp position S11, a busbar side wire clamp position S12 distributed along the second direction BB' and a bolt installation position S2 located therebetween. A pair of limiting tongues 21 corresponding to each wire clamp assembly position S1 are respectively located outside the bolt installation position S2 along the first direction AA', and will not interfere with the bolt installation position S2, nor will they interfere with the busbar and the drainage line.

[0123] For each wire clamp 40, the limit tongue 21 in the extended state presses the lower wire clamp portion 42 from top to bottom. During the screwing operation, the limit tongue 21 is located between the upper and lower wire clamp portions 41 and 42. Due to the thickness of the cable, the limit tongue 21 will not be clamped in the tightening state, so that after the installation of the wire clamp 40 is completed and the busbar 200 (see Figure 5 ) and drainage line 100 (see Figure 5 ) after being overlapped, the retraction and release of the limiting tongue 21 can be easily controlled to prepare for the unloading of the ignition receiving device.

[0124] Therefore, the position design of the limiting tongue 21 can be adjusted according to the specific structure and installation environment of the wire clamp 40 while ensuring that the axial HH′ limiting and the wire clamp installation can be realized, and is not limited by this embodiment.

[0125] In this embodiment, the limiting tongue 21 presses the wire clamp from top to bottom to achieve axial HH' limiting. In an optional embodiment, it can also be designed to abut the wire clamp from the side in the extended state to perform axial HH' limiting. At this time, a groove can be designed on the side of the wire clamp to make the limiting tongue insert into the groove in the extended state to form a limiting fit. At the same time, after the wire clamp is assembled, the limiting tongue can also retract smoothly to achieve easy separation.

[0126] In this embodiment, if Figure 7 and 8 As shown, the first driving mechanism 22 includes:

[0127] The first rotary motor 220 , illustratively, has a first motor output terminal 22a;

[0128] The first transmission mechanism 221 having a first rotation input end 22b and a first translation output end 22c is connected to the first motor output end 22a through the first rotation input end 22b to input rotational motion, and the first translation output end 22c is installed with the limit tongue 21. The first transmission mechanism 221 is configured to convert the rotational motion of the first rotation input end 22b into the telescopic motion of the first translation output end 22c and the limit tongue 21 along the first direction AA'.

[0129] During operation, the first rotary motor 220 is controlled to rotate forward and reverse, and the limiting tongue 21 is driven to extend and retract along the first direction AA' through the first transmission mechanism 221. Here, a motor controller is used to control the first rotary motor 220 by wire or wirelessly.

[0130] In the embodiment of the present disclosure, the first transmission mechanism 221 is a gear rack transmission mechanism. For example, the first transmission mechanism 221 includes:

[0131] A main gear 2210, a first rotation input end 22b is formed on the main gear 2210;

[0132] The racks meshing with the main gear 2210, such as the first rack 2211 and the second rack 2212, have the first translation output end 22c formed on the racks. In this embodiment, the first transmission mechanism 221 has two sets of first translation output ends 22c, corresponding to the first rack 2211 and the second rack 2212 one by one.

[0133] In this way, the first rotating motor 220 is coaxially connected to the main gear 2210, outputting synchronous rotation to the main gear 2210, which drives the first rack 2211 and the second rack 2212 to move horizontally, and drives the limiting tongue 21 to move horizontally synchronously to achieve telescopic drive along the first direction AA'.

[0134] In the embodiments of the present disclosure, Figure 3As shown, both sides of the clamp assembly position S1 are provided with limit tongues 21, and the first transmission mechanism 221 includes two racks respectively installed and arranged opposite to the limit tongues 21 on both sides, namely, a first rack 2211 and a second rack 2212. The main gear 2210 is located between the first rack 2211 and the second rack 2212 arranged opposite to each other.

[0135] In this embodiment, if Figure 7 As shown, the first rack 2211 drives the two limiting tongues 21a and 21b to move telescopically along the first direction AA'; the second rack 2212 drives the two limiting tongues 21c and 21d to move telescopically along the first direction AA'.

[0136] In this embodiment, the first rack 2211 and the second rack 2212 are meshed with the same main gear 2210. Thus, when the main gear 2210 rotates, the translation directions of the first rack 2211 and the second rack 2212 along the first direction AA' are exactly opposite, which ultimately results in the translation directions of the two limiting tongues 21a and 21c used to limit one of the wire clamps 40 along the first direction AA' being opposite, and the translation directions of the two limiting tongues 21b and 21d used to limit the other wire clamp 40 along the first direction AA' being opposite. That is, during operation, the pair of limiting tongues 21 used to limit the same wire clamp 40 and located on both sides of the wire clamp assembly position S1 extend synchronously toward each other or retract in the opposite direction relative to the wire clamp 40, corresponding to pressing the lower wire clamp portion 42 and releasing the downward pressure on the lower wire clamp portion 42. This structure not only reduces the number of components of the first transmission mechanism 221, but also enables synchronous extension and retraction control of the four limiting tongues 21a, 21b, 21c, and 21d corresponding to the two groups of wire clamps 40, thereby improving control accuracy.

[0137] In the embodiments of the present disclosure, Figure 3 and 7 As shown, two wire clamp assembly positions S1 distributed along the first direction AA′ are arranged on the base 10 ; along the first direction AA′, the limiting tongues 21 arranged on the same side of the two wire clamp assembly positions S1 are installed with the same rack.

[0138] Specifically, Figure 7 The first limiting tongue 21a and the second limiting tongue 21b are both located on the left side of the wire clamp assembly position S1, and are installed with the first rack 2211 through the first connecting portion 23. The third limiting tongue 21c and the fourth limiting tongue 21d are both arranged on the right side of different wire clamp assembly positions S1, and are installed with the second rack 2212 through the second connecting portion 24.

[0139] By using the first transmission mechanism 221 of this embodiment, the four limit tongues 21a, 21b, 21c, and 21d can be controlled to extend and retract synchronously through the first rotating motor 220, thereby further reducing transmission components and improving product integration. In addition, this embodiment can realize synchronous extension and retraction control of the four limit tongues 21a, 21b, 21c, and 21d, thereby improving control accuracy.

[0140] In this embodiment, the first rack 2211 and the second rack 2212 do not need to be long, and the first connecting portion 23 and the second connecting portion 24 are used to connect the limiting tongues on the same side of the two sets of wire clamp assembly positions S1.

[0141] In the embodiment of the present disclosure, the first rack 2211 and the second rack 2212 are located at a position between the two sets of wire clamp assembly positions S1. Figure 7 and Figure 8 The first rack 2211 and the second rack 2212 are opposite to each other, and the main gear 2210 is sandwiched between the first rack 2211 and the second rack 2212 and keeps meshing.

[0142] In an optional embodiment, different from the above embodiment, the two pairs of limit tongues can be provided with a first driving structure separately. For example, each first driving mechanism includes a first rotating motor and a rack and pinion transmission mechanism, the rack and pinion transmission mechanism includes a pair of racks and a common gear, a pair of limit tongues are respectively mounted on a pair of racks, and the common gear is arranged between the pair of racks and keeps meshing. In this case, the first rotating motors of the two wire clamp assembly positions can be controlled separately to control the extension and retraction of the two pairs of limit tongues separately.

[0143] In an optional embodiment, each limiting tongue may be provided with a first driving mechanism, the first driving mechanism comprising a first rotating motor and a rack and pinion transmission mechanism, so that the extension and retraction of each limiting tongue is individually controlled.

[0144] In an optional embodiment, unlike the gear rack transmission mechanism, the first transmission mechanism can also adopt a screw transmission mechanism. For example, the screw transmission mechanism includes a screw and sliders located at both ends of the screw. The screw adopts a double-threaded screw, and the spiral directions of the thread segments at both ends are opposite. A pair of limit tongues on both sides of the same wire clamp assembly are respectively installed with the sliders at both ends. The first rotating motor is connected to the screw to drive the screw to rotate. Since the spiral directions of the two ends of the screw are opposite, the pair of limit tongues move in opposite directions, realizing the movement towards each other or away from each other, thereby realizing synchronous telescopic control.

[0145] In this embodiment, the above-mentioned screw transmission mechanisms are respectively provided corresponding to the two pairs of limit tongues and cooperate with different first rotating motors, so that the extension and retraction control of the two pairs of limit tongues is realized separately.

[0146] It can also be that the screw rods on both sides of the screw transmission mechanism corresponding to the two pairs of limit tongues are arranged as transmission connections, for example, through belt transmission connection or gear transmission connection, and share a rotating motor to output rotational motion, so as to realize synchronous and unidirectional rotation of the screw rods on both sides, and then realize synchronous extension and retraction control of the two pairs of limit tongues.

[0147] In another embodiment, the first transmission mechanism may not be provided, and the first driving mechanism may also be a linear motor or a translational cylinder. For example, the translational output end of the linear motor is installed with the limiting tongue, and the linear motor directly drives the limiting tongue to extend and retract.

[0148] The various implementations of the first driving structure described above can be selected and designed according to a specific installation environment and are not limited here.

[0149] In the embodiments of the present disclosure, Figure 1 As shown, the drain line side line clamping position S11 has two drain line outlet ends D1 along the first direction AA'. Figure 1 As shown, the drainage line 100 is lifted (see Figure 5 ) stability during the transfer process, the ignition device also includes:

[0150] A clamping jaw assembly 70 is provided at least on one side of the drainage line side clamping position S11 along the first direction AA', and the clamping jaw assembly 70 includes:

[0151] The two side clamping jaws 71 are arranged along the second direction BB', and the drainage line side line clamping position S11 is opposite to the clamping area between the two side clamping jaws 71 along the first direction AA';

[0152] The third driving mechanism, which is transmission-connected to the clamping jaws 71 on both sides, is configured to be controlled to drive the clamping jaws 71 on both sides to move toward each other for clamping or move away from each other for separation along the second direction BB′.

[0153] The clamping jaw assembly 70 is used to clamp the drainage line 100 (see Figure 5 ) After the line is inserted, clamp the drainage line 100 (see Figure 5 In actual operation, in the initial state, the clamping jaws 71 are in a separated state, and the manipulator carries the ignition device to move to the drainage line 100 (see Figure 5 ) position, the drainage line 100 (see Figure 5 ) enters the pre-tightened wire clamping space 4a on the drainage wire side of the wire clamp 40 and between the above-mentioned clamping jaws 71, and controls the third driving mechanism to drive the clamping jaws 71 on both sides to clamp the drainage wire 100 (see Figure 5 ), then, the robot arm is operated to move the drainage line 100 (see Figure 5 ) to the upper busbar 200 (see Figure 5 ) position. During the movement, the clamping jaws 71 on both sides clamp the drainage line 100 (see Figure 5 ), prevent drainage line 100 (see Figure 5 ) is disengaged from the pre-tightened wire clamp 40, thereby enhancing operation reliability.

[0154] After the fire connection device is completed, the wire clamp 40 is installed and the busbar 200 is realized (see Figure 5 ) and drainage line 100 (see Figure 5 ) after the overlap, the jaw assembly 70 opens to release the drainage line 100 (see Figure 5 ), the limiting tongue 21 retracts to release the downward pressure on the lower wire clamp portion 42, and then the ignition device is lowered to achieve separation from the wire clamp 40.

[0155] In the above embodiment, Figure 2 and Figure 3 As shown, the fire connection device includes a limit tongue 21 and a first spring 32. The limit tongue 21 is used to axially limit the wire clamp 40 during the process of screwing the wire clamp. The first spring 32 is used to push the bolt sleeve 31 to move upward with the bolt 50 to prevent the bolt sleeve 31 from being separated from the bolt head. In another embodiment, the fire connection device may not include the limit tongue and the first spring. In this case, the screwing transmission mechanism is configured to transmit the rotational motion to the bolt sleeve until the wire clamp in the wire clamp assembly position is tightened, block the axial translation of the bolt sleeve from being transmitted to the second drive mechanism, and after the wire clamp is tightened, block the rotational motion of the second drive mechanism from being transmitted to the bolt sleeve.

[0156] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
