DETAILED DESCRIPTION

[0038] The following is combined with Figures 1 to 15 This application is described in further detail.

[0039] The embodiment of the present application discloses an insulating operating rod for live detection, which can switch the working head without retracting the working head, thereby realizing uninterrupted detection operations. At the same time, an insulating protection area can be formed at the detection position during the detection process to avoid arc breakdown during the detection process.

[0040] like Figure 1As shown, an insulating operating rod for live detection includes a connecting mechanism 2, which is arranged in multiple sections and spliced ​​together end to end. An adjusting mechanism 4 is arranged on the top connecting mechanism 2, and two left-right symmetrical anti-arc breakdown protection mechanisms 3 are arranged on the adjusting mechanism 4. An insulating protection area is formed by the protection mechanism 3 to avoid arc breakdown during the detection process. An auxiliary mechanism 1 is arranged on the bottom connecting mechanism 2.

[0041] like Figure 2 As shown, the connecting mechanism 2 includes a connecting rod 22 arranged up and down, a mounting hole 24 is opened at the top of the connecting rod 22, a plurality of limiting balls 25 distributed in a circular array are elastically slidably connected to the inner circumferential surface of the mounting hole 24, a connecting pin 21 is fixedly connected to the bottom end of the connecting rod 22, a clamping piece 23 is arranged at the top of the outer circumferential surface of the connecting rod 22, and an annular limiting groove is opened on the circumferential surface of the connecting pin 21.

[0042] like Figure 3 As shown, the clamping member 23 includes two symmetrical second limiting grooves 234 opened on the outer circumferential surface of the connecting rod 22, and the second limiting grooves 234 are fixedly connected with the second limiting slide rods 233 arranged up and down inside, and the second sliding blocks 232 are connected with the circumferential surface of the second limiting slide rods 233 for sliding up and down, and the two second sliding blocks 232 are fixedly connected with an adjusting sleeve 231, and the adjusting sleeve 231 is slidably connected to the connecting rod 22, and the inner side of the top end of the adjusting sleeve 231 is chamfered.

[0043] During specific use, first connect multiple connecting rods 22 end to end, clamp the connecting pin 21 on the previous connecting rod 22 into the mounting hole 24 on a connecting rod 22, and at the same time push the adjusting sleeve 231 to slide downward. At this time, the adjusting sleeve 231 is separated from the limiting ball 25, and under the action of elastic force, the limiting ball 25 moves in the direction away from the axis of the connecting rod 22. At this time, the connecting pin 21 on the previous connecting rod 22 can smoothly enter the inside of the mounting hole 24.

[0044] When the connecting pin 21 completely enters into the interior of the mounting hole 24, the adjusting sleeve 231 is released. Since the second sliding block 232 and the second limiting sliding rod 233 are elastically slidably connected, the adjusting sleeve 231 is restored to its original position under the action of elastic force. When the inner circumferential surface of the adjusting sleeve 231 contacts the limiting ball 25, the limiting ball 25 is pushed to move in the direction close to the axis of the connecting rod 22, and the limiting ball 25 is clamped in the inside of the annular limiting groove on the connecting pin 21, so that the two connecting rods 22 are quickly connected together.

[0045] like Figure 4 and Figure 5As shown, the protection mechanism 3 includes two left-right symmetrical connecting members 33 arranged on the adjustment mechanism 4, and an insulating protection unit 32 is hinged on the connecting member 33. The upper and lower surfaces of the insulating protection unit 32 are both provided with limit members 31.

[0046] like Figure 5 , Figure 6 and Figure 7 As shown, the insulating protection unit 32 is composed of a connecting plate and a folding protective sleeve, and a folding protective sleeve is arranged between the two connecting plates, wherein the connecting plate and the folding protective sleeve are both made of insulating material to achieve the purpose of arc isolation; taking the limiting member 31 on the upper side as an example, the limiting member 31 includes a fixing plate 311 fixedly connected to the upper surface of the rear end connecting plate of the insulating protection unit 32, the front end of the fixing plate 311 is hinged with a clamping plate 312, the upper surface of the front end connecting plate of the insulating protection unit 32 is fixedly connected with a connecting sleeve 313, the front end of the clamping plate 312 is fixedly connected to the limiting plate 314, and the clamping plate 312 is slidably connected to the connecting sleeve 313.

[0047] like Figure 5 and Figure 7 As shown, the connecting member 33 includes an adjustable telescopic seat 332 fixedly connected to the adjusting mechanism 4, the telescopic end of the adjustable telescopic seat 332 is fixedly connected to the connecting seat 331, and the connecting seat 331 is fixedly connected to an X-elastic telescopic articulated frame 333 on the side away from the adjustable telescopic seat 332, and the four corners of the X-elastic telescopic articulated frame 333 are hinged to the four corners of the insulating protection unit 32.

[0048] In specific use, such as Fig.15 The insulating protection unit 32 is in a folded state as shown in the figure, that is, the insulating protection unit 32 is in a stored state at this time. When multiple connecting rods 22 are spliced ​​as needed, the adjustable telescopic seat 332 on the adjustment mechanism 4 is first stretched to a suitable length according to the width of the working environment, and then the clamping plate 312 is rotated on the fixed plate 311 so that the clamping plate 312 and the fixed plate 311 are located at the same horizontal line. Since the X-elastic telescopic hinge frame 333 itself has elasticity, the X-elastic telescopic hinge frame 333 that is contracted together at this time opens under the action of elastic force, driving the insulating protection unit 32 to stretch at the same time. As the connecting piece 33 continues to open, the fixed plate 311 is driven to slide inside the connecting sleeve 313. When the limiting plate 314 contacts the connecting sleeve 313, the fixed plate 311 is limited at this time, and the X-elastic telescopic hinge frame 333 can no longer continue to open and remains motionless, and the insulating protection unit 32 always remains in a stretched state, that is, Figure 4 and Figure 5 In the state shown, an insulating protection area is formed between the two insulating protection units 32, so the adjustment mechanism 4 is placed in the middle position to avoid arcing during operation and arc breakdown.

[0049] like Figure 8 and Fig. 9 As shown, the adjustment mechanism 4 includes a fixed column 41 which is clamped in the mounting hole 24, a mounting slot is provided at the top of the fixed column 41, a rotating disk 42 is rotatably connected inside the mounting slot, a plurality of working heads 43 are threadedly connected on the circumferential surface of the rotating disk 42, a mounting box 44 is provided on the right side of the circumferential surface of the fixed column 41, a switching member 45 for switching the working head 43 is provided inside the mounting box 44, auxiliary rollers 46 arranged on the left and right are rotatably connected to the inner bottom end of the mounting box 44, and the bottom end of the fixed column 41 is provided with a structure same as the connecting pin 21.

[0050] During specific use, after the insulating protection unit 32 is opened, the fixing column 41 is installed on the connecting rod 22 at the top end of the multi-section connecting rod 22. The installation method is the same as the connection method of the multi-section connecting rod 22. After the fixing column 41 is connected to the connecting rod 22, the installation column 11 is connected to the connecting rod 22 at the bottom end of the multi-section connecting rod 22 in the same way. Then the auxiliary mechanism 1 cooperates with the switching member 45 to adjust the working head 43, and selects a suitable working head 43 for use.

[0051] like Fig. 9 , Fig.10 and Fig.11 As shown, the switching member 45 includes a mounting cylinder 453 fixedly connected to the right inner wall of the mounting box 44, the left end of the mounting cylinder 453 is rotatably connected to the second rotating disk 452, the left inner wall of the mounting box 44 is rotatably connected to the first rotating disk 451, two pushing pawls 455 are evenly distributed on the inner circumference of the second rotating disk 452, the left side of the first rotating disk 451 is fixedly connected to the second ratchet 456, the left inner wall of the mounting box 44 is elastically hinged with a non-return pawl 457, and the non-return pawl 45 7 is meshed with the second ratchet 456, the right side of the first rotary disk 451 is fixedly connected with the first ratchet 454, the first ratchet 454 is meshed with the pushing pawl 455, the second rotary disk 452 is also fixedly connected with a traction rope, the traction rope on the second rotary disk 452 away from the second rotary disk 452 One end passes through the outside of the installation box 44 and is fixedly connected with a female head of a quick connector (not shown in the figure), and a spiral spring (not shown in the figure) is arranged between the second rotary disk 452 and the installation cylinder 453.

[0052] like Fig.12 As shown, the auxiliary mechanism 1 includes a mounting column 11 which is clamped on a connecting pin 21, a sliding member 14 which moves up and down is arranged on the circumferential surface of the mounting column 11, a mounting box 12 is arranged on the right side of the sliding member 14, a winding member 15 for winding up the traction rope is arranged inside the mounting box 12, a clamping member 13 for limiting the traction rope is arranged on the upper surface of the mounting box 12, and a structure identical to the clamping member 23 is arranged on the top of the mounting column 11.

[0053] like Fig.13 and Fig.14 As shown, the winding member 15 includes a winding wheel 152 rotatably connected to the inside of the installation box 12, and a connecting roller 153 parallel to the winding wheel 152 is rotatably connected inside the installation box 12 and located above the winding wheel 152. A handle 151 is rotatably connected to the rear side of the installation box 12, and a linkage shaft is provided between the handle 151 and the winding wheel 152. A traction rope is wound around the winding wheel 152, and the end of the traction rope on the winding wheel 152 away from the winding wheel 152 passes through the upper surface of the installation box 12 and is fixedly connected with a male head of a quick connector (not shown in the figure, and the male and female quick connectors are prior art and will not be described in detail in this article), and a through rectangular groove matching the traction rope on the winding wheel 152 is opened on the upper surface of the installation box 12.

[0054] During specific use, when the position of the mounting column 11 is installed, a traction rope of a suitable length is pulled out from the winding wheel 152, and the traction rope on the second turntable 452 is quickly connected with the quick-connect male and female heads. Then, the second turntable 452 is driven to rotate a certain distance on the mounting tube 453 by pulling the traction rope. At this time, the spiral spring contracts, and when the second turntable 452 rotates, the pawl 455 is pushed to rotate synchronously therewith. During the rotation, the pawl 455 is pushed to engage with the first ratchet 454 to push the first turntable 451 to rotate synchronously. During the rotation, the first turntable 451 drives the rotating disk 42 to rotate on the fixed column 41, so that the positions of multiple different types of working heads 43 on the rotating disk 42 are switched. When switching to the required working head 43, stop pulling the second turntable 452.

[0055] After pulling the second turntable 452, the pulling force on the traction rope is released. At this time, the second turntable 452 is reversed and reset due to the elastic force of the spiral spring itself. At this time, the check pawl 457 abuts against the second ratchet 456, so that when the second turntable 452 is reversed and reset, the first turntable 451 remains stationary. The above steps can be repeated to cyclically switch the position of the working head 43. The working head 43 can be adjusted to an upward position as needed, and the traction rope can be smoothly moved inside the installation box 44 in conjunction with the setting of the auxiliary roller 46.

[0056] like Fig.13 and Fig.14As shown, the clamping member 13 includes two front-to-rear symmetrical sliding rails 135 fixedly connected to the upper surface of the installation box 12, and two left-to-right symmetrical clamping strips 131 are slidably connected to the two sliding rails 135. The left end of the sliding rail 135 is fixedly connected to a base 136, and the right side surface of the base 136 is rotatably connected to a bidirectional screw 134. A transmission box 133 is fixedly connected to the right side of the upper surface of the installation box 12, and a handle 132 is rotatably connected to the right side surface of the transmission box 133. The right end of the bidirectional screw 134 passes through the interior of the transmission box 133 and is driven by a belt (not shown in the figure). The bidirectional threads on the bidirectional screw 134 are threadedly connected to the two clamping strips 131 respectively.

[0057] like Fig.13 and Fig.14 As shown, the sliding member 14 includes two front-to-back symmetrical first limiting grooves 143 opened on the circumferential surface of the mounting column 11, and the first limiting grooves 143 are internally fixedly connected with first limiting slide rods 142 arranged up and down, and the two first limiting slide rods 142 are elastically slidably connected with a first sliding block 141, and the first sliding block 141 is slidably connected to the mounting column 11.

[0058] During specific use, after the installation of the mounting column 11 is completed, the traction rope on the winding wheel 152 is pulled out to a suitable length and connected to the traction rope on the second turntable 452. Then, the handle 151 is rotated to drive the winding wheel 152 to rotate and tighten the traction rope, so that the traction rope remains straight. Then, the handle 132 is rotated to drive the two bidirectional screws 134 to rotate synchronously through the belt, so that the two clamping bars 131 move towards each other on the sliding track 135. As the clamping bar 131 continues to move, the traction rope is clamped.

[0059] Then, the first sliding block 141 is pushed downward on the first limiting sliding rod 142 to drive the installation box 12 to move downward. At this time, since the clamping bar 131 clamps the traction rope, the downward pulling force of the installation box 12 acts on the traction rope through the clamping bar 131, so that the traction rope is subjected to downward pulling force, driving the second turntable 452 to rotate on the installation cylinder 453. When the downward pushing force on the first sliding block 141 is cancelled, since the first sliding block 141 and the first limiting sliding rod 142 are elastically slidingly connected, under the action of elastic force, the first sliding block 141 can be restored to its original position, and the pulling force on the traction rope is cancelled at the same time, thereby achieving the purpose of driving the rotating disk 42 to rotate on the fixed column 41 to adjust the position of the working head 43 by pulling the second turntable 452 to rotate through the traction rope.

[0060] After the operation is completed, first cancel the limit on the traction rope, separate the two traction ropes at the same time, drive the reel 152 to reverse through the handle 151 to reel in the excess traction rope on the reel 152, then remove the auxiliary mechanism 1 from the connecting rod 22, and tighten the X-elastic telescopic hinge frame 333 to drive the insulation protection unit 32 to fold. When the connection position of the fixed plate 311 and the clamping plate 312 passes through the connecting sleeve 313, the clamping plate 312 is rotated on the fixed plate 311 so that the clamping plate 312 is perpendicular to the fixed plate 311, that is, Fig.15 The state shown is used to limit the X-elastic telescopic articulated frame 333, so that the X-elastic telescopic articulated frame 333 remains in a tightened state, and then the fixing column 41 is removed from the connecting rod 22, and finally the multi-section connecting rod 22 is disassembled section by section according to the reverse steps of assembly. When all the disassembly is completed, the multiple parts are stored together for the next use.

[0061] Therefore, the present application can switch the working head 43 by cooperating with the switching member 44 and the sliding member 14 for different detection situations without retracting the working head 43, so that when performing detection in various situations, the detection efficiency is higher and the staff has fewer operating steps; at the same time, an insulating protection safety area is formed at the detection position by the insulating protection unit 32, which can avoid the arc formed during the detection process and the occurrence of arc breakdown, thereby further improving the scope of application of the present application.

[0062] The implementation principle of this application is:

[0063] (1) First, according to the use environment, select a suitable number of connecting mechanisms 2 for assembly, connect multiple connecting mechanisms 2 end to end, insert the connecting rod 22 of the previous connecting mechanism 2 into the mounting hole 24 of the next connecting mechanism 2, and cooperate with the clamping piece 23 and the limiting ball 25 to enable the two connecting mechanisms 2 to be quickly connected.

[0064] (2) When all the connection mechanisms 2 are assembled, the adjustment mechanism 4 is installed on the top connection mechanism 2 among the assembled multiple connection mechanisms 2. The method of installing the adjustment mechanism 4 is the same as the method of assembling the multiple connection mechanisms 2.

[0065] (3) At this time, the insulation protection unit 32 is opened to form an insulation protection area, and the telescopic length of the adjustable telescopic seat 332 is adjusted according to the width of the working position. At the same time, the opened insulation protection unit 32 is limited by the limiter 31, and then the installation of the adjustment mechanism 4 is started.
