Description

Technical Field

[0001] The invention relates to the technical field of wire clamp installation, and in particular to an automatic operation device and an operation method for live working. Background Art

[0002] Traditional live-line working requires workers to operate high-voltage live devices at close range, such as installing parallel groove wire clamps and puncture wire clamps, which poses a great risk to personal safety. Under severe weather conditions, such as high temperature, severe cold, strong wind, etc., the operating difficulty and danger of workers will be further increased, and the operation time will be longer.

[0003] At present, the safer method of installing the parallel groove clamp on the live main line is to fix the parallel groove clamp on the end of the insulating operating rod, fix the lead wire into the lead wire groove of the parallel groove clamp, and then send the parallel groove clamp to the live main line through the insulating operating rod, and then control the electric wrench to tighten the nuts on the parallel groove clamp one by one through another insulating operating rod to lock the main line. Another way to tighten the nuts is to install an electric wrench on the same insulating operating rod, and the rotating shaft of the electric wrench drives multiple meshing gears to rotate synchronously at the same time. Each gear is provided with a sleeve that fits with each nut of the parallel groove clamp, so that each nut is tightened at the same time. However, this method is only applicable to torque nuts, because if it is an ordinary nut, the number of turns required to tighten each nut may be different, so there will be a situation where the electric wrench cannot continue to rotate after some nuts are tightened, while other nuts have not been unscrewed.

[0004] In the above-mentioned prior art, the operation method using double operating levers requires the operator to operate with both hands. When the operator is in the pole tower or the lifting bucket, there is no grasping of the pole tower or the bucket. The risk factor of single-person aerial work is high, and the labor cost of double-person work is high. If an electric wrench is installed on a single operating lever to drive multiple sockets to synchronously tighten nuts, it is limited to tightening multiple torque nuts at the same time, and cannot be applied to ordinary non-torque nuts. Summary of the invention

[0005] The object of the present invention is to provide an automatic operating device and an operating method for live working to solve the deficiencies in the above-mentioned prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic operation device for live working, comprising an insulating rod and a tool body fixedly mounted on the insulating rod and capable of clamping at least one parallel groove wire clamp, and further comprising: a track, which is slidably connected to the tool body along the Y axis through a bracket, and an electric wrench is slidably connected to the track along the Z axis through a sliding hoop; a first elastic member, whose elastic force acts on the electric wrench in the opposite direction of the sequence in which each nut to be tightened is tightened; a fixed plate, which is fixedly connected to the tool body, and a guide groove group is provided on the fixed plate, and the guide groove group includes a plurality of parallel ones arranged along the Y axis.

The stroke has the following steps: in the first stroke, the slide column slides along the first guide groove to disengage the sleeve of the electric wrench from the tightened nut; in the second stroke, the slide column slides into the next adjacent first guide groove through the second guide groove, so that the sleeve is aligned with the next nut to be tightened.

[0007] Furthermore, along the direction in which the nuts to be tightened are tightened, the second guide groove gradually tilts away from the parallel groove wire clamp.

[0008] Furthermore, along the direction of the sequence in which the nuts to be tightened are tightened, the other first guide grooves except the first first guide groove include a first groove section, a second groove section and a third groove section connected in sequence, the junction between the first groove section and the second groove section is connected to the next second guide groove, and the junction between the second groove section and the third groove section is connected to the previous second guide groove; the first first guide groove only has the first groove section, and the bottom of the first groove section is connected to the next second guide groove.

[0009] Furthermore, a plurality of valve components are rotatably connected to the fixed plate, each valve component corresponds to each second guide groove one by one, each valve component has a first valve stem, and each valve component has a first position in its rotation stroke so that its first valve stem closes the corresponding oblique lower end of the second guide groove, and a second elastic component is arranged between the valve component and the fixed plate, and the elastic force of the second elastic component keeps the first valve stem in the first position.

[0010] Furthermore, along the direction of the sequence in which the nuts to be tightened are tightened, the valve components other than the last valve component also include a second valve stem fixedly connected to the first valve stem. When it is located at the first working position, the second valve stem closes the top of the second groove section of the corresponding first guide groove.

[0011] Furthermore, the second elastic member includes a torsion spring, which is movably sleeved on the rotating shaft between the corresponding valve member and the fixed plate, one end of the torsion spring is fixedly connected to the corresponding valve member, and the other end is fixedly connected to the fixed plate.

[0012] Furthermore, the sliding post is rotatably connected to the sliding hoop, and the sliding post and the guide groove are in rolling cooperation.

[0013] Furthermore, the driving assembly includes an electric push rod fixedly mounted on the tool body or the insulating rod, and a power output end of the electric push rod is fixedly connected to the bracket.

[0014] Furthermore, the first elastic member includes a clockwork spring and a rope. The clockwork spring is installed at one end of the track. The elastic force of the clockwork spring can reel the rope. The open end of the rope is fixedly connected to the sliding hoop.

During the screwing process, the driving component drives the track and the electric wrench to move along the Y-axis close to the parallel groove wire clamp to adapt to the axial displacement of the nut. When the first nut is tightened, the driving component drives the track and the electric wrench to move the first stroke to disengage from the tightened nut, and then the driving component drives the track and the electric wrench to continue to move the second stroke to align with the next nut to be tightened. In this way, each nut can be screwed in turn, and it can be suitable for torque nuts and non-torque nuts. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-Figure 10An automatic operating device for live working provided by an embodiment of the present invention comprises an insulating rod 1 and a tool body 2 fixedly mounted on the insulating rod 1 and capable of clamping one or two parallel groove wire clamps 100, and further comprises a rail 3, an electric wrench 6, a first elastic member, a fixing plate 8, a sliding column 7 and a driving assembly. The two ends of the rail 3 are respectively fixedly connected with brackets 4, and the brackets 4 are slidably inserted into the tool body 2 along the Y-axis, that is, the rail 3 can be slidably matched with the tool body 2 along the Y-axis. A sliding hoop 5 is welded or screwed on the shell of the electric wrench 6, and the sliding hoop 5 is slidably sleeved on the rail 3 along the Z-axis, that is, the electric wrench 6 is slidably connected to the rail 3 along the Z-axis.

[0032] The elastic force of the first elastic member acts on the electric wrench 6 in the opposite direction of the order in which the nuts to be tightened are tightened. Specifically, the first elastic member includes a spring and a rope 92. The spring is installed in a spring box 91. The spring box 91 is rotatably connected with a shaft. The spring is wound on the shaft, and its inner end is fixedly connected to the shaft, and its outer end is fixedly connected to the spring box 91. The spring box 91 is fixedly connected to the end of the track 3 (the starting end along the direction in which the nuts to be tightened are tightened) or the bracket 4. One end of the rope 92 is wound on the shaft, and the other end passes through the through hole on the spring box 91 and is tied to the sliding hoop 5 or the housing of the electric wrench 6.

[0033] The fixing plate 8 is fixedly connected to the tool body 2. A guide groove group is provided on the fixing plate 8. The guide groove group includes a plurality of parallel first guide grooves 81 arranged along the Y axis. Each first guide groove 81 corresponds to each nut on the parallel groove clamp 100. An inclined second guide groove 82 is connected between two adjacent first guide grooves 81. Along the direction of the screwing sequence of each nut to be screwed, the second guide groove 82 gradually tilts away from the parallel groove clamp 100. Specifically, along the direction of the screwing sequence of each nut to be screwed, the other first guide grooves 81 except the first first guide groove 81 include a first groove section 811, a second groove section 812 and a third groove section 813 connected in sequence. The junction of the first groove section 811 and the second groove section 812 is connected to the next second guide groove 82, and the junction of the second groove section 812 and the third groove section 813 is connected to the previous second guide groove 82. The first first guide groove 81 has only the first groove section 811, and the bottom of the first groove section 811 is connected to the next second guide groove 82.

[0034] A plurality of valve components are rotatably connected to the fixed plate 8, each valve component corresponds to each second guide groove 82, and each valve component has a first valve stem 831. Each valve component has a first position in the rotation stroke where the first valve stem 831 closes the oblique lower end of the corresponding second guide groove 82. Along the direction of the order in which the nuts to be tightened are tightened, the other valve components except the last valve component also include a second valve stem 832 fixedly connected to the first valve stem 831. When it is in the first position, the second valve stem 832 closes the top of the second groove section 812 of the corresponding first guide groove 81.

[0035] A second elastic member is provided between the valve member and the fixed plate 8, and the elastic force of the second elastic member keeps the first valve stem 831 in the first position, and in the first position, the end of the first valve stem 831 abuts against the side wall of the corresponding second guide groove 82. Specifically, the second elastic member includes a torsion spring 84, which is movably sleeved on the rotating shaft between the corresponding valve member and the fixed plate 8, one end of the torsion spring 84 is fixedly connected to the corresponding valve member, and the other end is fixedly connected to the rotating shaft fixedly connected to the fixed plate 8.

[0036] The slide post 7 is fixedly arranged on the housing of the slide hoop 5 or the electric wrench 6, and the slide post 7 is slidably matched with the guide groove group; or, the slide post 7 is rotatably connected to the slide hoop 5 or the housing of the electric wrench 6, and the slide post 7 is rollingly matched with the guide groove.

[0037] The driving assembly is used to drive the track 3 to move along the Y axis. The driving assembly is preferably an electric push rod 10. The base of the electric push rod 10 is fixedly mounted on the tool body 2 or the insulating rod 1. The power output end of the electric push rod 10 is fixedly connected to the bracket 4. The electric push rod 10 can drive the bracket 4, the track 3 and the electric wrench 6 to move on the Y axis. The electric wrench 6 follows the track 3 to move along the Y axis away from the parallel groove clamp 100. The stroke has a first stroke and a second stroke in sequence. In the first stroke, the slide column 7 slides along the first guide groove 81 to disengage the sleeve 61 of the electric wrench 6 from the tightened nut; in the second stroke, the slide column 7 slides into the adjacent next first guide groove 81 through the second guide groove 82, so that the sleeve 61 is aligned with the next nut to be tightened.

[0038] The present invention can be operated by one person with one hand. The parallel groove wire clamp 100 clamped on the tool body 2 is sleeved on the main line 200 through the insulating rod 1, and then the device is started, and the electric wrench 6 starts to screw the first nut. During the screwing process, the driving component drives the track 3 and the electric wrench 6 to move along the Y axis close to the parallel groove wire clamp 100 to adapt to the axial displacement of the nut. When the first nut is tightened, the driving component drives the track 3 and the electric wrench 6 to move the first stroke to disengage from the tightened nut, and then the driving component drives the track 3 and the electric wrench 6 to continue to move the second stroke to align with the next nut to be tightened. In this way, each nut can be screwed in turn, and it can be suitable for torque nuts and non-torque nuts.

[0039] The operation method and principle of the present invention are as follows: ① First, a plurality of parallel groove clamps 100 are clamped in parallel to the tool body 2, and the sleeve 61 of the electric wrench 6 is aligned with the first nut to be tightened of one of the parallel groove clamps 100, and the slide post 7 is located in the first first guide groove 81 (along the direction in which the nuts to be tightened are tightened), as shown in FIG. Figure 6 Then, the parallel groove clamp 100 is put onto the main line 200 through the insulating rod 1.

[0040] ② Then start the driving assembly to insert the sleeve 61 into and screw the nut to be screwed to a preset position. During this period, the electric push rod 10 drives the track 3, the electric wrench 6, the first elastic member and the slide post 7 to move along the Y axis through the bracket 4 to approach the parallel groove clamp 100 to adapt to the axial displacement of the nut, and the slide post 7 slides up in the first first guide groove 81.

[0041] ③ Next, the electric push rod 10 drives the electric wrench 6 to move away from the parallel groove clamp 100, so that the electric wrench 6 moves in the first stroke and the second stroke in sequence. In the first stroke, the slide column 7 slides along the first guide groove 81 to disengage the sleeve 61 of the electric wrench 6 from the tightened nut. In the second stroke, the slide column 7 slides through the first second guide groove 82 into the third groove section 813 of the next adjacent first guide groove 81 (the second first guide groove 81), so that the sleeve 61 is aligned with the next nut to be tightened. During this period, when the slide column 7 enters the third groove section 813, it squeezes the first valve stem 831 of the corresponding valve member (the first valve member) located at the first station, so that the valve member overcomes the elastic force of the torsion spring 84 thereon and rotates out of the first station, as shown in FIG. Figure 7 , the slide post 7 can smoothly enter the next first guide groove 81 (the second first guide groove 81). The purpose of the slide post 7 entering the third groove section 813 is to avoid the first valve stem 831, so that the elastic force of the torsion spring 84 can reset the valve member to the first position. Figure 8 , so that the first valve stem 831 blocks the oblique lower end of the first second guide groove 82 again.

[0042] ④ Then the electric push rod 10 drives the electric wrench 6Y axis to move close to the parallel groove clamp 100 so that the sleeve 61 is sleeved on the aligned nut to be tightened (the second nut). During this period, the slide column 7 slides from the third groove section 813 to the second groove section 812 and then slides into the first groove section 811. Since the first valve stem 831 blocks the passage into the first second guide groove 82, the slide column 7 can smoothly enter the second groove section 812 from the third groove section 813. When the slide column 7 enters the first groove section 811 from the second groove section 812, the slide column 7 squeezes the second valve stem 832, so that the second valve stem 832 overcomes the elastic force of the torsion spring 84 on it and avoids the slide column 7. Fig. 9 After the slide column 7 completely enters the first groove section 811, the slide column 7 no longer squeezes the second valve stem 832, and the elastic force of the torsion spring 84 is released to reset the valve member to the first position again, and the second valve stem 832 blocks the passage from the first groove section 811 to the second groove section 812.

[0043] ⑤ After the electric wrench 6 has tightened the nut (the second nut) it is aligned with, the electric push rod 10 controls the electric wrench 6 to move away from the parallel groove clamp 100, so that the electric wrench 6 moves the first stroke and the second stroke in sequence. In the first stroke, the slide column 7 slides along the first guide groove 81 (the second first guide groove 81) to disengage the sleeve 61 of the electric wrench 6 from the tightened nut. In the second stroke, the slide column 7 slides through the first second guide groove 82 (the second second guide groove 82) into the third groove section 813 of the next adjacent first guide groove 81 (the third first guide groove 81), so that the sleeve 61 is aligned with the next nut to be tightened. During this period, when the slide column 7 slides to the junction of the first groove section 811 and the second groove section 812 of the second first guide groove 81, since the second valve stem 832 of the corresponding valve member (the first valve member) in the first station blocks the passage to the second groove section 812, the slide column 7 can smoothly enter the next second guide groove 82 (the second second guide groove 82), as shown in FIG. Fig.10 By analogy, all nuts to be tightened can be tightened eventually, so that the installation of each parallel groove wire clamp 100 is completed.

[0044] ⑥ After all nuts are tightened, the slide post 7 moves away from the spring in the Z-axis direction, so the rope 92 is released and stretched, and the spring is further energized. The electric push rod 10 first controls the electric wrench 6 to move the first stroke, allowing the sleeve 61 to detach from the last nut, and then the tool body 2 is detached from the installed parallel groove clamp 100 through the insulating rod 1, and then the electric push rod 10 drives the electric wrench 6 to move in the opposite direction, allowing the slide post 7 to detach from the guide groove group from the top opening of the last first guide groove 81 (the end of its first groove section 811 away from the second groove section 812). At this time, after the slide post 7 is detached from the restriction of the guide groove group, the elastic force of the spring is released to reel the rope 92, and the rope 92 pulls the electric wrench 6 back to the initial position along the track 3, and the slide post 7 is aligned with the first first guide groove 81 again, and can enter the first first guide groove 81 under the control of the electric push rod 10, and the entire device is reset.

[0045] In the present invention, the parallel groove clamp 100 includes an upper clamping plate 110 and a lower clamping plate 120 connected by bolts, and the upper clamping plate 110 is provided with a main line groove 112 and a lead groove 111 distributed in parallel, and the tool body 2 is provided with a structure for clamping the parallel groove clamp 100, such as a clamping claw, a magnetic suction block, etc. In a more preferred technical solution provided by the present invention, at least one parallel groove clamp 100 groove is provided on the tool body 2, and a limit rod is provided at the parallel groove clamp 100 groove, and the upper clamping plate 110 of the parallel groove clamp 100 can be clamped into the parallel groove clamp 100 groove and abut against the limit rod, the lead 300 is placed in the lead groove 111, and a V-shaped cone block 11 is slidably connected to the tool body 2 along the X-axis. A spring 12 is arranged between the V-shaped cone block 11 and the tool body 2. The elastic force of the spring 12 causes the V-shaped cone block 11 to be inserted between the lead 300 and the lower clamping plate 120, so that the lead can be positioned in the lead groove 111, the upper clamping plate 110 is positioned in the groove of the parallel groove clamp 100, and the lower clamping plate 120 and the upper clamping plate 110 are spread apart, so that the main line can be conveniently inserted into the main line groove 112. In the process of tightening the nut to lock the main line and the lead, the V-shaped cone block 11 can be automatically squeezed out from between the lower clamping plate 120 and the lead, so that the tool body 2 can be conveniently separated from the parallel groove clamp 100 after it is installed.

[0046] Among them, the X-axis, Y-axis and Z-axis are three mutually perpendicular directions in the three-dimensional space.

[0047] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
