Description

Technical Field

[0001] The invention belongs to the technical field of live fire connection, and relates to fire connection operation equipment and a fire connection operation control method thereof. Background Art

[0002] Live connection is a high-risk electrical operation. It requires cutting the suspended end of the drain wire at the sub-bracket of the high-voltage power pole to an appropriate length and connecting it to the high-voltage busbar under power. The fixed end of the drain wire remains fixed at the sub-bracket. If the drain wire is too long, it will sag too much after connection, posing a danger to passers-by. Therefore, the length of the drain wire after cutting should not be too long. The traditional method of live connection is for strictly trained technical workers to wear insulating clothing and carry insulating working tools to perform the operation. In order to ensure the safety of the operators, live connection equipment is currently used.

[0003] The wire stripper of the current fire connection equipment rotates and moves horizontally during the wire stripping operation, and the entire fire connection equipment needs to move horizontally with the wire stripper. After the wire stripping is completed, the entire fire connection equipment needs to continue to move horizontally so that the wire clamp fire connector drags the drainage wire to the stripping section of the busbar for fire connection. There is a large gap between the initial online position of the wire clamp fire connector and the fire connection position. When the wire is initially online, the estimated drainage wire length is appropriate, but during actual wiring, the drainage wire moves forward a large amount with the wire clamp fire connector. It is likely that the drainage wire is not long enough to move to the stripping position until the wire clamp fire connector can no longer drag the drainage wire forward, which affects the smooth progress of the fire connection operation and causes unnecessary waste of time. Summary of the invention

[0004] The purpose of the present invention is to provide a fire connection operation equipment and a fire connection operation control method thereof, which overcomes the technical problem in other related technologies that the fire connection operation equipment is difficult to determine whether the length of the dragged drainage line is appropriate when it is put online.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: The invention discloses a fire connection operation device, comprising: Pedestal; A wire stripper located on the base and a first driving mechanism matched therewith, the first driving mechanism having a first translation output end, the first translation output end being rotationally connected to the wire stripper, the first driving mechanism being configured to drive the wire stripper to move between a first position and a second position relative to the base along a first direction through the first translation output end; A wire clamp fire connector mounted on the base and a second driving mechanism matched therewith, wherein the second driving mechanism is configured to drive the wire clamp fire connector to move between a third position and a fourth position along the first direction relative to the base; The first position, the third position, the second position and the fourth position are arranged in sequence on the same straight line along the first direction; The wire clamp fire connector comprises a fire connector mounting seat and a drainage wire clamp fixedly arranged on the fire connector mounting seat.

[0006] Based on the above-mentioned fire connection operation equipment, the present invention also discloses a fire connection operation control method, comprising the following steps: Before the wire stripper performs the wire stripping operation, the drain wire clamp clamps the drain wire, and the second driving mechanism drives the wire clamp fire connector to drag the drain wire from the third position to the fourth position; The first driving mechanism drives the wire stripper to make a reciprocating movement from the first position to the second position, and controls the wire stripper to perform a wire stripping operation during the movement toward the second position or during the return to the first position; After the wire stripper returns to the first position, the second driving mechanism drives the wire clamp fire connector to drag the drainage wire from the fourth position back to the third position to perform the fire connection operation.

[0007] Furthermore, a base busbar clamp is provided on the base, and the base busbar clamp is located on a side of the wire stripper away from the wire clamp fire connector; The wire clamp fire connector is provided with a fire connector busbar clamp, and the fire connector busbar clamp is located on a side of the wire clamp fire connector away from the wire stripper; Before the second driving mechanism drives the wire clamp fire connector to translate from the third position to the fourth position, when the busbar is located in the clamping space of the base busbar clamp and the fire connector busbar clamp, the base busbar clamp and the fire connector busbar clamp are controlled to clamp the busbar, and the clamping force of the base busbar clamp on the busbar is greater than the clamping force of the fire connector busbar clamp on the busbar.

[0008] Furthermore, when the second driving mechanism drives the wire clamp fire connector to translate between the third position and the fourth position, the base busbar clamp clamps the busbar, the fire connector busbar clamp remains clamped, and the clamping force of the fire connector busbar clamp is configured so that the fire connector busbar clamp can translate relative to the busbar.

[0009] Compared with the prior art, the present invention has the following beneficial effects: Before the fire connection operation equipment is put online, the wire clamp fire connection device is located at the third position relative to the base, and the drainage wire clamp of the wire clamp fire connection device clamps the drainage wire. After the fire connection operation equipment is put online, the base is fixed relative to the busbar. Before the wire stripping operation, the second driving mechanism drives the wire clamp fire connection device to drag the drainage wire from the third position to the fourth position to make room for the wire stripper. The first driving mechanism drives the wire stripper to move back and forth from the first position to the second position, and controls the wire stripper to perform the wire stripping operation during the movement toward the second position or during the return to the first position. After the wire stripper returns to the first position, the second driving mechanism drives the wire clamp fire connection device to drag the drainage wire from the fourth position back to the third position to perform the fire connection operation. The wire clamp fire connection device's online position and the fire connection operation position are both in the third position. After the fire connection operation equipment is put online, it can be judged whether the drainage wire length in the fire connection operation stage is appropriate, so that it can be judged in advance whether the drainage wire length is suitable for the operation. Among them, the process of the wire clamp fire connector dragging the drain wire from the third position to the fourth position is moving toward the high-voltage pole where the fixed end of the drain wire is located. Therefore, this process does not require additional increments in the length of the drain wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the original position, the wire stripper 2 is located at the first position, and the wire clamp connector 3 is located at the third position.

[0017] The fire connection operation equipment is online for the fire connection operation equipment to rise to the high busbar 8 position, so that the busbar 8 enters the wire stripper 2 and the wire clamp fire connection device 3. In this embodiment, the fire connection operation equipment is raised to the high busbar 8 by using the telescopic support frame 6.

[0018] After the fire connection operation equipment is put online, the position of the base 1 relative to the busbar 8 is fixed, and the base 1 is not separated from the busbar 8 until the fire connection operation equipment completes the fire connection operation and goes offline.

[0019] In this embodiment, a base busbar clamp 4 is provided on the base 1, and the base busbar clamp 4 is located on the side of the wire stripper 2 away from the wire clamp fire connector 3.

[0022] In this embodiment, the first optical coupling component 403 includes two first optical coupling units arranged vertically.

The first driving mechanism 201 is configured to drive the wire stripper 2 to move between a first position and a second position relative to the base 1 along a first direction AA' through the first translation output end 202, and control the wire stripper 2 to perform a wire stripping operation during the process of moving toward the second position or during the process of returning to the first position. After the wire stripping operation is completed, the wire stripper 2 is controlled to return to the first position.

[0029] The second driving mechanism 301 is configured to drive the wire clamp fire arrester 3 to move between a third position and a fourth position along the first direction AA′ relative to the base 1 .

[0030] The first position, the third position, the second position and the fourth position are arranged in sequence on the same straight line along the first direction AA', that is, the wire stripper 2 and the wire clamp connector 3 can move on the same straight line on the base 1.

The transmission belt 206 is tensionedly sleeved on the first driving gear 209 and the first driven gear 205.

[0036] The first motor output end 213 of the first rotating motor 203 drives the first gear set 212, and the first gear set 212 drives the first driven gear 205 through the transmission belt 206. The transmission belt 206 drives the first translation output end 202 to translate during the movement, and the first translation output end 202 drives the first sliding member 207 (see Figure 4 ), thereby driving the wire stripper 2 to move between the first position and the second position along the first direction AA'.

[0037] See also Figure 7 In this embodiment, two first optical couplers 204 are arranged on the path of the translational movement of the transmission belt 206. The two first optical couplers 204 are respectively used to sense the translation of the wire stripper 2 to the first position and the second position, so as to accurately control the start and stop of the first rotating motor 203.

[0038] In this embodiment, an encoder 210 is installed on the rotating shaft of the first driving gear 209 for detecting the translation amount of the wire stripper 2. The encoder 210 is used to measure the rotation direction and stroke information of the rotating shaft of the first driving gear 209, so as to judge the position of the wire stripper 2 according to the feedback information and to accurately control the rotation and translation of the wire stripper 2.

[0039] refer to Figure 7 and Figure 8 In this embodiment, the first sliding member 207 is fixedly mounted on the first translation output end 202, and the wire stripper 2 (reference Figure 4 ) is installed by a rotation connection with the first sliding member 207, the wire stripper 2 (reference Figure 4 ) moves synchronously with the first sliding member 207 and can rotate relative to the first sliding member 207.

[0040] In this embodiment, the wire stripper 2 is provided with a skin-core detection sensor (not shown in the figure).

[0041] See also Figure 2 The wire clamp fire connector 3 is provided with a fire connector busbar clamp 5 and a wire clamp placement portion 302 and a wire clamp screwing mechanism 303 installed on the fire connector mounting seat 304.

[0042] In this embodiment, the wire clamp screwing mechanism 303 is located outside the wire clamp placement portion 302 along the second direction BB', the second direction BB' is perpendicular to the first direction AA', and the second direction BB' is perpendicular to the first direction AA' and the base height direction CC'.

[0043] The wire clip placement portion 302 uses a spring element to ensure that it presses against the wire clip 310 .

[0044] See also Fig. 9 and Fig.10 The wire clamp screwing mechanism 303 includes a screwing sleeve 312 and a third driving mechanism 313 cooperating with the screwing sleeve 312. The screwing sleeve 312 points to the wire clamp placement portion 302 along the second direction BB'. The screwing sleeve 312 is configured to screw the pre-tightening bolt on the wire clamp 310 to be installed placed in the wire clamp placement portion 302; the third driving mechanism 313 is configured to drive the screwing sleeve 312 to rotate under control so as to screw the pre-tightening bolt until the wire clamp 310 to be installed reaches the clamping position.

[0045] See also Fig. 9 and Fig.11 In this embodiment, the wire clamp 310 has a lower drain wire channel and an upper busbar channel, which are used to accommodate the drain wire and the busbar respectively. The drain wire channel is connected with the drain wire clamp 309 in the open state along the first direction AA'.

[0046] In this embodiment, during the online stage of the fire connection operation equipment, the process of the busbar 8 entering the wire clamp fire connection device 3 is the process of the busbar 8 entering the busbar channel of the wire clamp.

[0050] refer to Figure 2 and Fig.11 In this embodiment, the second side wall 501 has a second line entry opening 502 at the top. The second side wall 501 is provided with a second pair of optical coupling components 503, which are configured to be triggered when the busbar 8 is detected to enter the second line entry opening 502, that is, when the busbar 8 passes through the second line entry opening 502, the optical path of the second pair of optical coupling components 503 will be blocked, thereby accurately detecting the line entry state of the busbar 8, so as to control the busbar clamp 5 of the fire connector to clamp the busbar 8.

[0051] In this embodiment, the second optical coupling component 503 includes two second optical coupling units arranged vertically.

[0052] When the second pair of optocoupler units below is triggered and the second pair of optocoupler units above is not triggered, it indicates that the busbar 8 has correctly entered the busbar fixture 5 of the fire detector.

[0053] See also Figure 2 In this embodiment, the drainage wire clamps 309 are located on both sides of the wire clamp placement portion 302 along the first direction AA'.

[0054] Before the fire connection equipment is put online, the drainage line clamp 309 of the wire clamp fire connection device 3 is used to clamp the drainage line 7. During the online process, the telescopic support frame 6 raises the fire connection equipment to the high busbar 8, and the wire clamp fire connection device 3 uses the drainage line clamp 309 to drag the drainage line online.

[0055] See also Figure 1 and Figure 3 Before the wire stripping operation begins, the second driving mechanism 301 drives the wire clamp fire connector 3 to translate from the third position to the fourth position to make room for the wire stripper 2 to work. After the wire stripper 2 completes the wire stripping operation and returns to the first position, the second driving mechanism 301 drives the wire clamp fire connector 3 to return from the fourth position to the third position, and the wire clamp fire connector 3 starts the fire connection operation.

[0056] See also Figure 2 During the fire connection operation stage, the wire clamp fire connector 3 tightens the wire clamp 310 through the wire clamp screwing mechanism 303, thereby overlapping the drainage wire and the busbar stripping section together.

[0057] refer to Fig.10 In this embodiment, the second driving mechanism 301 includes: a second rotating motor 305 and a second transmission mechanism 311.

[0059] refer to Figure 7 and Figure 8 In this embodiment, the second transmission mechanism 311 further includes a second screw transmission pair 307 fixedly mounted on the base 1, and the second screw 306 (refer to Fig.10 ) passes through the second screw transmission pair 307; through the rotation limit of the second screw transmission pair 307, the rotational motion of the second screw 306 is converted into the fire connection mounting seat 304 (reference Fig. 9 ) translational movement relative to the base 1 along the first direction AA'.

[0060] See also Fig.10 The second motor output end of the second rotating motor 305 drives the second screw rod 306 to rotate through the transmission component, thereby driving the fire connection mounting seat 304 to translate along the first direction AA', and then driving the wire clamp fire connection device 3 to translate between the third position and the fourth position.

[0061] refer to Fig. 9In this embodiment, a micro switch 308 is provided at each end of the second screw rod 306, and the micro switch 308 is configured to be in contact with the second screw rod transmission pair 307 (reference Figure 8 ) side walls are in contact with each other, which plays a limiting role and improves the control accuracy of the translation of the wire clamp firearm 3.

[0062] See also Figure 1 , Figure 3 and Figure 4 Before the fire connection operation equipment is put online, the wire clamp fire connection device 3 is located at the third position relative to the base 1, and the drainage line clamp 309 of the wire clamp fire connection device 3 clamps the drainage line 7. After the fire connection operation equipment is put online, the base 1 is fixed relative to the busbar 8. Before the wire stripping operation, the second driving mechanism 301 drives the wire clamp fire connection device 3 to drag the drainage line 7 from the third position to the fourth position to make room for the wire stripper 2. The first driving mechanism 201 drives the wire stripper 2 to make a reciprocating movement from the first position to the second position, and controls the wire stripper 2 to perform the wire stripping operation during the movement toward the second position or during the return to the first position. After the wire stripper 2 returns to the first position, the second driving mechanism 301 drives the wire clamp fire connection device 3 to drag the drainage line from the fourth position back to the third position to perform the fire connection operation. The line position of the wire clamp fire connector 3 and the fire connection operation position are both in the third position. After the fire connection operation equipment is online, it can be judged whether the length of the drain line 7 in the fire connection operation stage is appropriate, so that it can be judged in advance whether the length of the drain line 7 is suitable for the operation. Among them, the process of the wire clamp fire connector 3 dragging the drain line 7 from the third position to the fourth position is moving toward the high-voltage pole where the fixed end of the drain line 7 is located, so this process does not require additional increments in the length of the drain line 7.

[0063] See also Fig.15 This embodiment discloses a method for controlling a fire connection operation of a fire connection operation device, comprising the following steps: S1, before the wire stripper 2 performs the wire stripping operation, the second driving mechanism 301 drives the wire clamp fire connector 3 to translate from the third position to the fourth position; S2, the first driving mechanism 201 drives the wire stripper 2 to make a reciprocating movement from the first position to the second position, and controls the wire stripper 2 to perform a wire stripping operation during the movement toward the second position or during the return to the first position; S3, after the wire stripper 2 returns to the first position, the second driving mechanism 301 drives the wire clamp connector 3 to return from the fourth position to the third position.

[0064] In the fire connection operation control method, the online position of the wire clamp fire connection device 3 and the fire connection operation position are both in the third position. After the fire connection operation equipment is online, it is possible to judge whether the length of the drainage line 7 in the fire connection operation stage is appropriate, thereby being able to judge in advance whether the length of the drainage line 7 is suitable for the operation.

[0065] See also Fig.13 In this embodiment, before the second driving mechanism 301 drives the wire clamp fire connector 3 to translate from the third position to the fourth position, when the busbar 8 is located in the clamping space of the base busbar clamp 4 and the fire connector busbar clamp 5, the base busbar clamp 4 and the fire connector busbar clamp 5 are controlled to clamp the busbar 8, and the clamping force of the base busbar clamp 4 on the busbar 8 is greater than the clamping force of the fire connector busbar clamp 5 on the busbar 8, which facilitates the subsequent relative movement of the wire clamp fire connector 3 and the busbar 8.

[0066] In this embodiment, when the first pair of optocoupler units below is triggered and the first pair of optocoupler units above is not triggered, and the second pair of optocoupler units below is triggered and the second pair of optocoupler units above is not triggered, it means that the busbar 8 has correctly entered the base busbar clamp 4 and the ignition connector busbar clamp 5, and the base busbar clamp 4 and the ignition connector busbar clamp 5 are controlled to clamp the busbar 8.

[0067] In this embodiment, the process of controlling the base busbar clamp 4 and the fire connector busbar clamp 5 to clamp the busbar 8 also includes: controlling the guide clamp to clamp the busbar 8.

[0068] In this embodiment, the clamping force of the base busbar clamp 4 on the busbar 8 is F1. During the wire stripping operation of the wire stripper 2, the clamping force of the guide clamp on the busbar 8 is F2. The clamping force of the fire connector busbar clamp 5 on the busbar 8 is F3. The magnitude relationship of F1, F2 and F3 is: F1>F2>F3.

[0069] During the entire operation process from the online to offline operation of the fire connection operation equipment, the base busbar clamp 4 maintains a large clamping force on the busbar 8 to prevent the busbar 8 from rotating or the base 1 from translating relative to the busbar 8.

[0070] During the wire stripping operation, the wire stripper 2 needs to rotate around the busbar 8, whether in the cyclic feed stage or the rotational translation stripping stage. The guide clamp maintains a moderate clamping force on the busbar 8. On the one hand, it ensures that the rotation center of the wire stripper 2 is the busbar 8, reduces the deviation, and helps to reduce the probability of core cutting; on the other hand, the clamping surface of the guide clamp has guide lines, which are in contact with the surface of the busbar 8, so that the friction resistance of the busbar 8 to the guide clamp is converted into a translation trend or actual translation movement of the wire stripper 2 through the guide lines.

[0071] During the translation process of the wire stripper 2 outside the wire stripping operation phase, the guide clamp is opened and the wire stripper 2 is translated by the first sliding member 207 , that is, at this time, the first driving mechanism 201 is the only driving force source for the translation of the wire stripper 2 .

[0072] The clamping force of the fire connector busbar clamp 5 on the busbar 8 is relatively small. On the one hand, it is beneficial for the wire clamp fire connector 3 to make a translational movement relative to the busbar 8. On the other hand, compared with the fire connector busbar clamp being fully opened, the fire connector busbar clamp maintains the clamping force on the busbar 8, which helps to ensure that the busbar 8 is always in the fire connector busbar clamp 5 during the translation of the wire clamp fire connector 3.

[0073] Fig.13 Schematic diagram of the wire clamp fire arrester 3 in the third position, Fig.14 It is a schematic diagram showing that the wire clamp fire arrester 3 is located at the fourth position.

[0074] refer to Fig.13 and Fig.14 , step S1: after the base busbar clamp 4, the fire connector busbar clamp 5 and the guide clamp clamp the busbar 8, the second driving mechanism 301 drives the wire clamp fire connector 3 to translate from the third position to the fourth position, thereby making room for the wire stripping operation of the wire stripper.

[0075] In this embodiment, the wire clamp ignition device 3 drags the drain wire 7 from the third position to the fourth position, and moves toward the high-voltage pole where the fixed end of the drain wire 7 is located. Therefore, this process does not require additional increments in the length of the drain wire 7.

[0076] In this embodiment, during the translation of the wire clamp fire connector 3 between the third position and the fourth position, the fire connector busbar clamp 5 remains clamped, which helps to ensure that the wire clamp fire connector 3 moves along the busbar 8, and the busbar 8 is always in the wire clamp fire connector 3, preventing the busbar 8 from detaching from the wire clamp fire connector 3.

[0077] Fig.14 The middle wire stripper 2 is located at the first position, Figure 4 The middle wire stripper 2 is located at the second position.

[0078] refer to Fig.14 and Figure 4 Step S2: After the wire clamp connector 3 is translated to the fourth position, the first driving mechanism 201 drives the wire stripper 2 to move back and forth from the first position to the second position, and controls the wire stripper 2 to perform wire stripping operation during the movement toward the second position or during the return to the first position.

[0079] In this embodiment, the stripping operation includes a cyclic feed stage and a rotational translation stripping stage. In the cyclic feed stage, the first drive mechanism 201 is controlled to output a drag force to the wire stripper 2 through the first translation output end 202, so that the wire stripper 2 strips the wire in situ. In the rotational translation stripping stage, the first drive mechanism 201 is controlled to output a synchronous linear motion corresponding to the translation of the wire stripper 2 through the first translation output end 202 until the wire stripping end position, and a busbar stripping segment corresponding to the position interval between the wire stripping start position and the wire stripping end position is obtained.

[0080] In the cyclic feeding stage, the first driving mechanism 201 outputs a dragging force to the wire stripper 2, which can prevent the translation tendency of the guide clamp from being converted into an effective translation, so that the wire stripper 2 keeps rotating in place to strip the wire, or only translates forward a small amount.

[0081] During the rotational translation stripping stage, the guide clamp will be converted into an effective translation of the wire stripper 2, and the friction pair between the clamping surface and the busbar 8 will provide an effective driving force for the translation of the wire stripper 2.

[0082] Through the above control method, the controllability of the position of the busbar 8 stripping section is improved to ensure that after the fire-contact busbar clamp 5 returns to the third position, the wire clamp 310 on the fire-contact busbar clamp 5 is moved exactly to the busbar stripping section.

[0083] In this embodiment, as the cyclic feed stage proceeds, the core-skin detection sensor detects that the wire core has been stripped, and the wire stripping operation is transferred from the cyclic feed stage to the rotational translational stripping stage.

[0084] In this embodiment, during the rotational translation peeling process, according to the encoder 210 (see Figure 7 ) The translation amount of the wire stripper 2 is known, that is, the current length of the stripping section of the busbar 8 is known. When the length of the stripping section of the busbar 8 reaches the expected length, the rotational translation stripping stage is transferred to the pure translation stage of the wire stripper 8.

[0085] In the pure translation stage of the wire stripper 8, the guide clamp is opened, and the first driving mechanism 201 drags the wire stripper 2 back to the first position.

[0086] refer to Fig.13 and Fig.14 , step S3: after the wire stripper 2 returns to the first position, the second driving mechanism 301 drives the wire clamp connector 3 to return from the fourth position to the third position.

[0087] In this embodiment, when the second driving mechanism 301 drives the wire clamp fire connector 3 to translate between the third position and the fourth position, the base busbar clamp 4 clamps the busbar 8, and the fire connector busbar clamp 5 remains clamped, and the clamping force of the fire connector busbar clamp 5 is configured so that the fire connector busbar clamp 5 can translate relative to the busbar 8.

[0088] During the process of the wire clamp fire connector 3 returning from the fourth position to the third position, the fire connector busbar clamp 5 remains clamped, which helps to ensure that the wire clamp fire connector 3 moves along the busbar 8, and the busbar 8 is always in the wire clamp fire connector 3, preventing the busbar 8 from escaping from the wire clamp fire connector 3. The control method ensures that the wire clamp fire connector 3 can complete the fire connection operation when it only has the freedom to move in the first direction AA', without adding the freedom in the height direction.

[0089] The wire clamp fire connector 3 returns to the third position and moves to the point where the busbar 8 stripping section is located in the busbar channel of the wire clamp 310. The wire clamp fire connector 3 performs the fire connection operation, and the wire clamp screwing mechanism 303 tightens the wire clamp 310, thereby overlapping the drainage wire and the busbar stripping section together.

Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
