Description

Technical Field

[0001] The present invention relates to the field of electrical engineering technology, and in particular to an insulator replacement device, system and method. Background Art

[0002] Replacing damaged insulators is an important task in the maintenance of UHV transmission lines. Insulators are electronic components used to support conductors and keep a safe distance and insulation between the conductors and the ground and towers. During the operation of transmission lines, insulators are exposed to the outdoor wind, rain and lightning environment, and work under long-term strong electric fields and tension, which are prone to low or zero values. The appearance of zero or low values ​​in the same string of insulators will affect the voltage distribution of the entire string of insulators and promote the deterioration of other insulators. When the number of good pieces in the insulator string does not meet the safety regulations, it will threaten the safe operation of the transmission line, so the low-value or zero-value insulators of the line must be replaced regularly.

[0003] However, due to the need to reduce line losses, existing UHV lines are often arranged on mountains. In order to make it as convenient as possible during use, two manual hydraulic screws are often used to jointly disassemble and assemble insulators. The current suspension insulators are mainly connected by a locking mechanism with a locking pin. During disassembly, it is necessary to first fix the two insulators adjacent to the insulator to be replaced on two clamps respectively, and then shorten the distance between the insulators through a manual hydraulic screw to loosen the locking mechanism between the suspension insulators, so as to facilitate the removal of the locking pin and complete the disassembly of the insulators. In actual use, the locking pin at the insulator connection is often offset from the axis due to the different oil pressure of the hydraulic screw during manual pressing, causing damage to the connection during the insulator replacement process or even the risk of breakage. The replacement process is not only time-consuming and labor-intensive, but also has low operating efficiency and there is a risk of operators falling from heights. Summary of the invention

[0066] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0067] In the description of the present invention, it is necessary to understand that the terms "lateral", "width", "up", "left", "right", "inside", "outside", "counterclockwise" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0068] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0069] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0070] It should be noted that when an element is referred to as being "fixed" or "disposed" on another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "upper", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0071] At present, the suspension insulators are mainly connected by a locking mechanism with a locking pin. When disassembling, the staff needs to sit on the conductor and use a manual pump to fill oil for the two hydraulic mechanical screws respectively. After the mechanical screws are extended by the hydraulic oil, the insulator to be replaced is manually rotated in a direction perpendicular to the axis of the suspension insulator string, thereby opening the locking mechanism between the suspension insulators, and then the suspension insulator is taken out to complete the installation of the suspension insulator; when installing, the locking mechanism is first fixed, and then the mechanical screws are driven to shrink by the hydraulic oil, and the locking device is tightened and buckled to complete the installation of the suspension insulators.

[0072] The applicant found that in order to reduce line losses, most of the existing UHV transmission line towers are erected at high places such as hills. In order to ensure the safety of operators, a low-weight manual pump is usually used to provide hydraulic oil to the two mechanical screws respectively. When the operators pressurize the mechanical screws separately, they can only control the stroke of the mechanical screws based on experience. At the same time, it is also difficult to ensure that the oil pressures in the left and right hydraulic oil tanks are exactly the same, causing the locking pin at the insulator connection to deviate from the axis, which in turn leads to the breakage of the insulator string.

[0073] Based on the above problems, the applicant first thought that if an insulator replacement device that can be pressed by an electric pump is designed, the above problems can be avoided. However, after a lot of thinking and experiments, the applicant found that the problem cannot be solved simply by designing an electric pump. So far, there is no device that uses an electric pump for pressing on the market. The main reason is that according to the "Technical Specifications for Temporary Electricity Safety at Construction Sites" (JGJ46-2005), 380V power supply or 220V lighting power supply cannot be used in the field of high-altitude operations. If 220V or 380V AC power supply is not used, the required power supply volume and weight will be greatly increased. Therefore, the weight problem must be solved first before the electric pump can be set on the insulator replacement device. However, the main source of the weight of the existing insulator replacement device is the hydraulic oil tank and its components of the mechanical screw. In order to ensure a small stroke (S), a large force (F), and high stability, its volume and weight are difficult to be reduced. For this reason, there is currently no product on the market that can set an electric pump on an insulator replacement device with a double mechanical screw.

[0074] Therefore, the applicant started over again, aiming at the overall lightweighting of the insulator replacement device, and provided a lightweight insulator replacement device, which used machine pressing instead of manual pressing, thereby reducing the problem of the locking pin at the insulator connection being offset from the axis due to the different oil pressures of the left and right mechanical screws when the insulator string was disassembled and assembled.

[0076] Please refer again Figure 1 and Figure 2 The present application provides an insulator replacement device, including a hydraulic oil tank 10, a first clamp assembly 20, a second clamp assembly 40 and an oil supply assembly 50. A first adjustment mechanism 30 for adjusting the distance between the hydraulic oil tank 10 and the first clamp assembly 20 is arranged between the first clamp assembly 20 and the hydraulic oil tank 10, and the hydraulic oil tank 10 and the first clamp assembly 20 are connected through the first adjustment mechanism 30; the second clamp assembly 40 is fixedly connected to the hydraulic oil tank 10, and the first clamp assembly 20 and the second clamp assembly 40 are coaxially arranged; the oil supply assembly 50 is connected to the hydraulic oil tank 10, and the oil supply assembly 50 is used to provide or recover hydraulic oil for the hydraulic oil tank 10, so as to drive the first adjustment mechanism 30 to move along the first direction, and drive the first clamp assembly 20 to approach or move away from the hydraulic oil tank 10.

[0077] When the insulator replacement device is used, the first clamp assembly 20 and the second clamp assembly 40 are used to fix and position the insulator string 70, and the fixed insulators at both ends of the insulator 710 to be replaced are fixed in the first clamp assembly 20 and the second clamp assembly 40 respectively. The first clamp assembly 20 and the second clamp assembly 40 are arranged coaxially to preliminarily reduce the situation that the axis of the insulator string 70 is not uniform; then the hydraulic oil is provided to the hydraulic oil tank 10 by the oil supply assembly 50, and the hydraulic oil in the hydraulic oil tank 10 is used to drive the first adjustment assembly to drive the hydraulic oil tank 10 close to or away from the first clamp assembly 20, and the hydraulic oil is provided to the two first adjustment mechanisms 30 by the oil supply assembly 50, so as to replace the situation that the manual pump is used to provide hydraulic oil separately in the traditional technology, so as to ensure that the hydraulic oil pressure in the hydraulic oil tank 10 and the two first adjustment mechanisms 30 are the same, and further reduce the situation that the axis of the insulator string 70 is not uniform due to different hydraulic oil pressures when tightening or loosening the insulator string 70, and reduce the situation that the connection is damaged or even broken due to the non-uniform axis when the insulator is disassembled and assembled.

[0078] Specifically, the first clamp assembly 20 includes a first clamp piece 210 and a second clamp piece 220, one end of the first clamp piece 210 is hinged to the second clamp piece 220, and the other end of the first clamp piece 210 is detachably connected to the second clamp piece 220 by a first bolt; the second clamp assembly 40 includes a third clamp piece 410 and a fourth clamp piece 420, one end of the third clamp piece 410 is hinged to the fourth clamp piece 420, and the other end of the third clamp piece 410 is detachably connected to the fourth clamp piece 420 by a second bolt. In this way, the first clamp piece 210 can be opened along the hinge, and at the same time, when it needs to be fixed, it can be fixed by bolts at the detachable connection, which not only ensures the stability when fixing the insulator string 70, but also further simplifies the operation when fixing the insulator string 70.

[0079] In some embodiments, a first circular hole for fixing the insulator is formed by connecting the first clamping piece 210 and the second clamping piece 220, and a second circular hole for fixing the insulator is formed by connecting the third clamping piece 410 and the fourth clamping piece 420. The axial connection direction of the first clamping assembly 20 and the second clamping assembly 40 is the axial connection direction of the first circular hole and the second circular hole.

[0080] Please refer again Figure 3 and Figure 4 In some specific embodiments, the oil supply assembly 50 includes: a DC power supply 510, a control component 520, and a power pump 530. The DC power supply 510 is connected to the control component 520, and the power pump 530 is connected to the control component 520 and the hydraulic oil tank 10. The control component 520 controls the power pump 530 to perform oil discharge operations and oil return operations to drive the hydraulic oil to flow into or out of the hydraulic oil tank 10.

[0081] Specifically, the DC power supply 510 includes a low-voltage DC battery. The use of the low-voltage DC battery can meet the use requirements of the DC power supply 510 while ensuring a small stroke (S), a large force (F), and high stability. At the same time, the use of the low-voltage DC battery makes it less likely that the control component 520 will be short-circuited and burn out. The power pump 530 includes a micro power pump 530. The use of the micro power pump 530 can further reduce the weight of the device while ensuring that the oil supply component 50 can be fully supplied with oil.

[0082] More specifically, the oil supply assembly 50 also includes an oil supply housing 550, which is located outside the oil supply assembly 50 and is used to protect the oil supply assembly 50 and turn the oil supply assembly 50 from a part into a whole. The oil supply housing 550 is provided with a switch 551, a charging port 552, a heat dissipation vent 553 and a refueling port 555. The switch 551 is used to control the rotation of the power pump 530, the charging port 552 is used to charge the DC power supply 510, and the heat dissipation vent 553 is used to dissipate heat for the power pump 530 to prevent the power pump 530 from overheating. In case of a dangerous situation with the power pump 530 and the circuit, the refueling port 555 is used to refuel the oil supply assembly 50. When used for the first time, there is no oil in the oil supply assembly 50, and the oil filling port plug needs to be opened to fill the oil. New hydraulic oil can be injected into the power pump 530 through the refueling port 555. The oil supply housing 550 is also provided with a device handle 554. The device handle 554 is used for the operator to grab the entire insulator replacement device when working. Through the above arrangement, the operator can complete the oil supply operation and the insulator replacement operation alone, thereby reducing the labor cost.

[0083] Optionally, the oil supply assembly 50 may also consider adding a signal receiving antenna to receive signals transmitted remotely from a remote control or a mobile phone APP through the signal receiving antenna, thereby further increasing the degree of automation of the oil supply assembly 50.

[0084] Please refer again Figure 4 and Figure 5In some specific embodiments, the power pump 530 includes a pump body 5310, an oil supply container 5320, and a coupling 5330. The hydraulic oil is set in the oil supply container 5320. The oil discharge operation and the oil return operation are realized by the pump body 5310 controlling the hydraulic oil in the oil supply container 5320. The pump body 5310 is connected to the oil supply container 5320 through a coupling 5330. The coupling 5330 includes a first coupling 5330a, a second coupling 5330b, and a second coupling 5330c. The coupling member 5330b and the positioning member 5330c, the first coupling member 5330a is fixedly connected to the pump body 5310, the second coupling member 5330b is fixedly connected to the oil supply container 5320, the first coupling member 5330a is clamped with the second coupling member 5330b, the positioning member 5330c is arranged between the first coupling member 5330a and the second coupling member 5330b, and abuts against the first coupling member 5330a and the second coupling member 5330b.

[0085] Specifically, the power pump 530 can be configured as a plunger pump or a rotor pump or other power pump 530 with high self-priming, high stability and small stroke as required. The reciprocating part is arranged in the pump body 5310, and the interior of the oil supply container 5320 is a sealed space. The hydraulic oil is set in the sealed space. The volume of the sealed space inside the oil supply container 5320 is changed by the reciprocating part in the pump body 5310 to complete the oil discharge and return operations. In some embodiments, the pump body 5310 can be configured as a GS / DR series rotor pump.

[0086] Specifically, the oil supply assembly 50 also includes a frame 560, and the oil supply container 5320 and the pump body 5310 are fixedly connected to the frame 560 respectively, by fixing the first coupling 5330a to the pump body 5310, fixing the second coupling 5330b to the oil supply container 5320, the first coupling 5330a is clamped with the second coupling 5330b, and the positioning member 5330c is arranged between the first coupling 5330a and the second coupling 5330b, and is connected to the first coupling 5330a and the second coupling member 5330b are in abutment with each other. In actual use, if the pump body 5310 and the oil supply container 5320 have different axes, the positioning member 5330c can be used to unify the axes, thereby reducing damage to the pump body 5310 and the oil supply assembly 50 caused by the inconsistent rotation axes. Optionally, an overflow valve can be provided inside the oil supply container 5320 in accordance with conventional settings to control the stability of the oil supply pressure, and the present application does not impose any restrictions on this.

[0087] Please refer again Figure 1 and Figure 4More specifically, the oil supply container 5320 is also provided with an oil outlet pipe 5321, one end of the oil outlet pipe 5321 is fixedly connected to the oil supply container 5320, the oil supply assembly 50 is also provided with an oil supply pipe 540, the other end of the oil outlet pipe 5321 is fixedly connected to one end of the oil supply pipe 540, and the other end of the oil supply pipe 540 is fixedly connected to the hydraulic oil tank 10, and a discharge pipe 543, an oil supply valve 541 and a pressure gauge 542 are also provided at the connection between the oil supply pipe 540 and the oil outlet pipe 5321. The oil supply valve 541 is used to control the connection between the oil supply pipe 540 and the oil outlet pipe 5321, the discharge pipe 543 is used to discharge the air in the oil supply assembly 50 and the oil supply pipe 540 as well as the wasted oil after multiple operations, and the pressure gauge 542 is used to detect whether the oil supply assembly 50 and the oil supply pipe 540 are working normally and whether there is any leakage. The above arrangement further increases the reliability of the oil supply assembly 50 when supplying oil.

[0088] Please refer again Figure 1 , Figures 6 to 8 In some specific embodiments, the first adjustment mechanism 30 includes a telescopic rod 310 and a driving assembly 320, the hydraulic oil tank 10 is sleeved on the telescopic rod 310, one end of the telescopic rod 310 is slidably connected to the hydraulic oil tank 10, and the other end of the telescopic rod 310 is hinged to the first clamp assembly 20, and the driving assembly 320 is used to drive the telescopic rod 310 to move along the axis connecting the first clamp assembly 20 and the second clamp assembly 40 to adjust the distance between the hydraulic oil tank 10 and the first clamp assembly 20. Specifically, the telescopic rod 310 is hinged to the first clamp assembly 20, and the driving assembly 320 drives the telescopic rod 310 and the hydraulic oil tank 10 to generate relative movement in the first direction, so that the first clamp assembly 20 can be close to or away from the hydraulic oil tank 10. Compared with other adjustment methods, since the axes of the first clamp assembly 20 and the second clamp assembly 40 are unified, and the telescopic rod 310 can only move along the first direction, the situation of inconsistent axes when the insulator string 70 is disassembled and assembled is further reduced.

[0089] More specifically, a distance sensor 311 is also provided on the telescopic rod 310. The distance sensor 311 is used to detect the tightening distance of the telescopic rod 310. When the tightening distance exceeds the threshold, the distance sensor 311 sends an electrical control signal to automatically cut off the power to prevent the danger of the insulator string 70 breaking due to excessive tightening pressure. In some embodiments, the distance sensor 311 is configured as a laser rangefinder, a distance sensor and other sensors that can measure distance. The present application does not impose any restrictions on this. Optionally, an auxiliary camera can be set to observe the movement of the telescopic rod 310 (i.e., the length of the travel of the telescopic rod 310) to determine whether the insulator replacement device is in normal working condition. In some embodiments, the auxiliary camera can be set on the oil supply pipe 540 and set toward the telescopic rod 310. The present application does not impose any restrictions on how to set the camera and where to set the camera.

[0090] Preferably, an additional mounting hole can be opened on the telescopic rod 310, and the distance sensor 311 can be installed in the mounting hole, so as to further reduce the volume of the distance sensor. At the same time, it also makes the distance sensor 311 more firmly installed and less likely to shake when the telescopic rod 311 moves, thereby reducing the inaccurate distance measurement caused by the shaking of the distance sensor 311.

[0091] In some specific embodiments, the driving assembly 320 includes a piston head 3210, a sealing chamber 3220, a working chamber 3230, and a return spring 3231. The piston head 3210 is disposed inside the hydraulic oil tank 10. The piston head 3210 is fixedly connected to the telescopic rod 310. The piston head 3210 is slidably connected to the hydraulic oil tank 10. The piston head 3210 abuts against the inner wall of the hydraulic oil tank 10. The piston head 3210 separates the interior of the hydraulic oil tank 10 to form a sealing chamber 3220 and a working chamber 3230. 0, the sealing chamber 3220 is provided with an oil filling hole 3221, and the oil supply assembly 50 is provided with an oil supply pipe 540, one end of the oil supply pipe 540 is connected to the oil supply container 5320, and the other end of the oil supply pipe is connected to the oil filling hole 3221, and the hydraulic oil enters the sealing chamber 3220 through the oil supply pipe 540 and the oil supply hole. The return spring 3231 is arranged in the working chamber 3220, one end of the return spring 3231 is fixedly connected to the piston head 3210, and the other end of the return spring 3231 is fixedly connected to the hydraulic oil tank 10.

[0092] Specifically, the hydraulic oil tank 10 includes a main oil tank 110 and a sub-oil tank 120, the main oil tank 110 and the sub-oil tank 120 are fixedly connected, the piston head 3210 is arranged in the main oil tank 110, the sealed cavity 3220 is provided with an oil filling hole 3221, the oil supply container 5320 is provided with an oil supply pipe 540, the hydraulic oil enters or leaves the sealed cavity 3220 through the oil supply pipe 540 and the oil supply hole, and when the hydraulic oil enters the sealed cavity 3220, the hydraulic oil drives the piston head 3210 to move toward the working cavity 3230 (i.e., as shown in FIG. Figure 7 As shown, after the hydraulic oil enters the sealing chamber 3220, the piston head 3210 will move to the right); when the hydraulic oil leaves the sealing chamber 3220, the piston head 3210 is reset by the reset spring 3231 (ie: as shown in FIG. Figure 7 As shown, after the hydraulic oil leaves the sealing chamber 3220, the piston head 3210 will move toward the sealing chamber 3220 and reset).

[0093] More specifically, the oil filling hole 3221 is also provided with a mounting bolt 3222, and the mounting bolt 3222 is a hollow structure, which facilitates the hydraulic oil in the oil supply pipe 540 to enter the sealing chamber 3220 through the mounting bolt 3222 and the oil filling hole 3221. The mounting bolt 3222 is also provided with an oil overflow limiting valve 3223 for ensuring the stability of the hydraulic oil pressure and flow rate. The oil overflow valve can be selected and set in a conventional manner, and the present application does not make any requirements for this. In some embodiments, the piston head 3210 and the telescopic rod 310 can be integrally formed to simplify the process cost and process.

[0094] The above-mentioned driving assembly 320 replaces the manual pressing method in the traditional technology, so that after the hydraulic oil enters the hydraulic oil tank 10, the piston head 3210 can be directly controlled to move, reducing the uneven oil pressure caused by releasing the mechanical screw after manual pressing.

[0095] Please refer again Figure 1 In some specific embodiments, the insulator replacement device also includes a second adjustment mechanism 60, which is disposed at the connection between the second clamp assembly 40 and the hydraulic oil tank 10, and the distance between the hydraulic oil tank 10 and the second clamp assembly 40 is adjusted by the second adjustment mechanism 60.

[0096] Specifically, by setting up the second adjustment mechanism 60 to adjust the distance between the second clamp assembly 40 and the hydraulic oil tank 10, the second adjustment mechanism 60 can not only serve as a backup adjustment mechanism, but also work together with the first adjustment mechanism, further making the adjustment distance more efficient.

[0097] Please refer again Figures 6 to 9 In some specific embodiments, the second adjustment mechanism 60 includes a connecting rod 610 and a manual adjustment assembly 620, one end of the connecting rod 610 is hinged to the second clamp assembly 40, the hydraulic oil tank 10 is provided with a first opening 11, the hydraulic oil tank 10 is sleeved on the connecting rod 610 through the first opening 11, the connecting rod 610 is rotatably connected to the hydraulic oil tank 10, the manual adjustment assembly 620 is sleeved on the connecting rod 610, the manual adjustment assembly 620 is fixedly connected to the connecting rod 610, and the manual adjustment assembly 620 is used to drive the connecting rod 610 to move along the direction of the axis line connecting the first clamp assembly 20 and the second clamp assembly 40.

[0098] Specifically, the connecting rod 610 is adjusted by the manual adjustment component 620, so that when the hydraulic oil in the first adjustment mechanism 30 fails, pressurization and pressure relief can still be completed by the manual adjustment component 620 (that is, the same effect of pressurization and pressure relief is achieved by adjusting the distance between the second clamp assembly 40 and the hydraulic oil tank 10), making the insulator replacement device more versatile.

[0099] More specifically, if Figure 7 As shown, the first opening 11 is located at the auxiliary oil tank 120. In some embodiments, the connecting rod 610 includes a ball screw, one end of the connecting rod 610 is hinged to the second clamp assembly 40, and the other end of the connecting rod 610 is provided with a sealing bolt 611 for sealing the hydraulic oil tank 10. The piston head 3210 is provided with a positioning portion 3210a. When the piston head 3210 moves to the rightmost end of the auxiliary oil tank 120, the positioning portion 3210a abuts against the sealing bolt 611 to reduce the collision between the piston head 3210 and the auxiliary oil tank 120 due to the operator's lack of experience, and cause damage to the auxiliary oil tank 120 and the piston head 3210.

[0100] Please refer again Figures 9 to 11 In some specific embodiments, the manual adjustment component 620 includes a synchronous wheel 6210 and a check member 6220. The synchronous wheel 6210 is also provided with an auxiliary rotating wheel 6212. The synchronous wheel 6210 is fixedly connected to the mechanical handle 6260 through the auxiliary rotating wheel 6212. The auxiliary rotating wheel 6212 and the synchronous wheel 6210 are sleeved on the connecting rod 610. The auxiliary rotating wheel 6212 is located on the outside of the synchronous wheel 6210. The synchronous wheel 6210 is fixedly connected to the connecting rod 610. The synchronous wheel 6210 is fixedly connected to the hydraulic oil tank 10 through the first opening 11. The check member 6220 is provided with a protrusion 6221. The synchronous wheel 6210 is provided with a plurality of recessed portions 6211. The protrusion 6221 abuts against any side of the plurality of recessed portions 6211.

[0101] Specifically, by abutting the protrusion 6221 against one side of the inner recess 6211, when it is necessary to adjust the distance between the second clamp assembly 40 and the hydraulic oil tank 10, it is only necessary to rotate the check member 6220 to drive the synchronous wheel 6210 to rotate, thereby causing the connecting rod 610 and the auxiliary oil tank 120 to generate relative movement, so as to achieve the purpose of moving the auxiliary oil tank 120 away from or close to the second clamp assembly 40. More specifically, in one embodiment, as Fig. 9 and Fig.10 As shown, along Fig. 9 By rotating the check member 6220 counterclockwise, the synchronous wheel 6210 can be driven to rotate, thereby driving the second clamp assembly 40 away from the hydraulic oil tank 10. In some embodiments, the check member 6220 can also be arranged as a ratchet wrench, which is not limited in the present application.

[0102] In some specific embodiments, the manual adjustment assembly 620 further includes an outer shell 6230, a reversing member 6240 and a compression spring 6250, the outer shell 6230 is fixedly connected to the synchronous wheel 6210, the reversing member 6240 is disposed in the outer shell 6230, the inner recess 6211 includes a first side 6211a, the abutting surface 6221b abuts against the first side 6211a, the protruding portion 6221 includes abutting surface 6221b and a convex arc surface 6221a, and the convex arc surface 6221a abuts against the first side 6211a. The abutment surfaces 6221b are arranged opposite to each other, and a gap is provided between the convex arc surface 6221a and the inner recess 6211. The switching member 6240 is fixedly connected to the check member 6220. The inner recess 6211 also includes a second side 6211b. The switching member 6240 is used to control the abutment surface 6221b to separate from the first side 6211a and abut against the second side 6211b. One end of the compression spring 6250 is fixedly connected to the switching member 6240, and the other end of the compression spring 6250 abuts against the check member 6220.

[0103] Specifically, the manual adjustment assembly 620 includes an adjustment handle 6260, and the reversing member 6240 includes a hexagonal nut 6240a, a rotating shell 6240b and a clamping member 6240c. The adjustment handle 6260 is fixedly connected to the hexagonal nut 6240a, one end of the clamping member 6240c is fixedly connected to the other end of the hexagonal nut 6240a, and the other end of the clamping member 6240c is fixedly connected to the check member 6220. The rotating shell 6240b is located on the outside of the clamping member 6240c and abuts against the clamping member 6240c. When in use, Fig. 9 , Fig.10 As shown, when the adjustment handle 6260 rotates horizontally, the hexagonal nut 6240a is driven to rotate horizontally, and then the hexagonal nut 6240a is driven to rotate horizontally, so that the clamping member 6240c and the check member 6220 are driven to rotate together. At the same time, since the convex arc surface 6221a and the inner recess 6211 are provided with a gap, not only the check member 6220 has the ability to stop when in use, but also the abutting surface 6221b of the check member 6220 can be directly turned to abut the second side 6211b of the inner recess 6211 when the check member 6220 rotates, so that the manual adjustment component 620 can be used to move the hydraulic oil tank 10 away from the second clamp assembly 40, or to move the hydraulic oil tank 10 close to the second clamp assembly 40. At the same time, the check piece 6220 is compressed by the compression spring 6250, so that the check piece 6220 can better drive the synchronous wheel 6210 to rotate. Furthermore, when the abutment surface 6221b needs to be reversed, the adjustment handle 6260 can be lifted first to eliminate the compression force of the compression spring 6250, and then the adjustment handle 6260 can be rotated to complete the reversal of the abutment surface 6221b.

[0104] More specifically, during use, by setting the convex arc surface 6221a and limiting the width of the inner recess 6211, when the synchronous wheel 6210 rotates, the protrusion 6221 can just fall into any one of the inner recesses 6211. At the same time, since the convex arc surface 6221a does not contact the inner recess 6211, when the check member 6220 reverses (rotation perpendicular to the rotation axis of the hexagonal nut 6240a above), the abutment surface 6221b will not drive the synchronous wheel 6210 to reverse, so that the check member 6220 has a non-return effect, which can better save the operator's working space at high altitudes and also save the operator's physical strength. In some embodiments, the check member can be configured as a ratchet wrench and other driving members with a non-return effect, which is not limited in the present application.

[0105] In some specific embodiments, the first adjustment mechanism 30 and the second adjustment mechanism 60 are made of titanium alloy material.

[0106] Specifically, the applicant found that in order to achieve lightweight insulator replacement devices, it is still necessary to start with the device materials. After a lot of thinking and reference, the applicant found that titanium alloy materials have the advantages of light weight, high specific strength, and good corrosion resistance, but titanium alloys have poor process performance and low wear resistance, which makes cutting difficult and the production process complicated. During the processing, it is very easy to absorb impurities such as hydrogen, oxygen, nitrogen, and carbon, which affect the quality of the workpiece. The hardness of titanium alloys is only one aspect of the difficulty in cutting. The key lies in the comprehensive influence of the chemical, physical, and mechanical properties of titanium alloys on their cutting processability. Due to the shortcomings of titanium alloy materials such as small deformation coefficient, high cutting temperature, large cutting force per unit area, severe cold hardening phenomenon, easy wear of cutting tools, and low thermal conductivity of titanium alloy materials, the difficulty of processing is greatly increased. Most of the insulator replacement devices in traditional technologies only use titanium alloys for auxiliary purposes at the connection part.

[0107] The present application creatively uses titanium alloy to make the first adjustment mechanism 30 and the second adjustment mechanism 60, which greatly reduces the weight of the device. The first adjustment mechanism 30 and the second adjustment mechanism 60 of titanium alloy are made of special cutting tools and molds for cutting titanium alloy materials. Not only does it meet the structural strength requirements of the first adjustment mechanism 30 and the second adjustment mechanism 60, but it also greatly reduces the weight of the entire device.

[0108] Please refer again Figures 1 to 12 The present application also provides an insulator replacement system, characterized in that it includes the above-mentioned insulator replacement device, the insulator replacement device is provided with a PLC integrated module and a remote control module, the remote control module is used to send a remote control signal, the PLC integrated module is connected to a controller, the controller is used to receive the remote control signal, and control the insulator replacement device to provide power according to the remote control signal.

[0109] Specifically, the remote control module includes a control center, a base station and a remote controller. In some embodiments, the remote controller may also be an electronic device such as a mobile phone or a laptop computer that can send signals to the base station. The base station may include a 3G base station, a 4G base station, a 5G base station and other base stations that can receive signals. Specifically, Fig.12 As shown, after sending a signal to the 4G base station through a mobile phone APP or a remote control, the signal is converted into a PLC program language through the control center, and then the program language is sent to the controller. The controller controls the motor in the power pump 530 to rotate forward and reverse to complete the oil inlet and oil return operations, and drive the external load (the first adjustment mechanism 30) to disassemble and assemble the insulator. In some embodiments, the maximum distance between the remote control and the remotely controlled PLC is 1 km. After exceeding 1 km, the controller's ability to receive signals will decrease, causing the remote control to reduce sensitivity.

[0110] In addition to manual control, the above-mentioned insulator replacement system can also be remotely controlled by a remote control or a mobile phone APP, which not only ensures the personal safety of the operator, but also makes the insulator replacement system more automated, which is more conducive to reducing labor costs.

[0111] Please refer again Figures 1 to 12 The present application also provides a method for using an insulator replacement device, which specifically includes:

[0112] S100, providing the above-mentioned insulator replacement device, wherein the insulator replacement device is provided with a controller;

[0113] S200, fixing two fixed insulators 720 adjacent to the insulator 710 to be replaced on the first clamp assembly 20 and the second clamp assembly 40;

[0114] S300, use a mobile phone or remote control to issue a hydraulic oil supply command to the controller;

[0115] S400, the controller converts the signal into a control requirement, and controls the insulator replacement device to provide hydraulic oil according to a set mode;

[0116] S500, the controller starts a countdown according to a preset program. After the controller countdown ends, the insulator 710 to be replaced is taken out, and a new insulator is put in its original place;

[0117] S600, use a mobile phone or remote control to issue a command to the controller to recycle hydraulic oil;

[0118] S700, the controller controls the insulator replacement device to recycle hydraulic oil;

[0119] S800, after the insulator replacement device recovers the hydraulic oil, the first clamp assembly 20 and the second clamp assembly 40 are opened to complete the replacement of the insulator.

[0120] When the above-mentioned insulator replacement device, system and method are used, the insulator string 70 is fixed and positioned by the first clamp assembly 20 and the second clamp assembly 40, and the fixed insulators at both ends of the insulator 710 to be replaced are respectively fixed in the first clamp assembly 20 and the second clamp assembly 40. The first clamp assembly 20 and the second clamp assembly 40 are arranged coaxially to preliminarily reduce the situation that the axis of the insulator string 70 is not uniform; the hydraulic oil is then provided to the hydraulic oil tank 10 by the oil supply assembly 50, and the hydraulic oil in the hydraulic oil tank 10 is used to drive the first adjustment assembly to drive the hydraulic oil tank 10 to move closer to or away from the first clamp assembly 20, and the two first adjustment machines are provided by the oil supply assembly 50. The hydraulic oil is provided by the first adjustment mechanism 30 to replace the situation in which a manual pump is used to provide hydraulic oil separately in the traditional technology, thereby ensuring that the hydraulic oil pressure in the hydraulic oil tank 10 and the two first adjustment mechanisms 30 are the same, further reducing the situation in which the axis of the insulator string 70 is not uniform due to different hydraulic oil pressures when tightening or loosening the insulator string 70, and reducing the risk of damage to the connection due to the non-uniform axis when the insulator is disassembled and assembled. At the same time, a low-voltage DC power supply 510, a power pump 530 and a highly integrated hydraulic oil tank 10 are used, and finally the first adjustment mechanism 30 and the second adjustment mechanism 60 are made of titanium alloy material, which greatly reduces the weight of the device.

[0121] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0122] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
