Description

Technical Field

[0001] The present invention relates to the technical field of power auxiliary equipment, in particular to a method and a combined tool for live installation or replacement of a wind-proof insulator. Background Art

[0002] Wind-proof insulator strings are electrical auxiliary equipment used to control the position of transmission line leads. They prevent the leads from swaying under wind, which could result in insufficient safety distance between the leads and the tower, leading to short circuits and tripping. Wind-proof insulator strings are typically installed on tension towers. Tension towers have three-layer crossarm structures, with wind-proof insulator strings suspended at both ends of each crossarm structure, and leads fixed to the wind-proof insulator strings. Because personnel need to climb onto the crossarms on each layer of the tension tower to replace the wind-proof insulator strings, It should be noted that there are three layers of cross arms on the tension pole tower. The working space on the top layer, which is the first layer, is sufficient to directly replace the wind-proof insulator string. However, problems occurred during the construction of the second and third layers. At this time, the lead wires of the upper layer were hung above the heads of the personnel, and the distance was too close. The traditional live installation or replacement of wind-proof insulator strings on transmission lines is limited by the insufficient safety distance, which limits the operating space of the operators. The installation or replacement of wind-proof insulator strings can only be carried out by power outage, which greatly reduces the power supply reliability. Summary of the Invention

[0003] The purpose of the present invention is to provide a method and a combination tool for live installation or replacement of wind-proof deflection insulators. The combination tool and method can safely and efficiently install or replace a string of wind-proof deflection insulators without power outage, solving the technical problem of insufficient safety distance and low power supply reliability in traditional live installation or replacement of wind-proof deflection insulator strings in the background technology, and requiring power outage for operation.

[0004] To achieve the above object, the present invention provides the following technical solutions: A method for live installation or replacement of a wind-proof insulator comprises the following steps: Use a branch pole to support the upper live lead, then install an insulating fork pulley rod on the working layer and configure an insulating lifting rope, connect the insulating lifting rope to the insulating locking rod, and then use the insulating locking rod to clamp the live lead on the working layer, tighten the insulating lifting rope, so as to position and control the live lead, and finally replace the wind-proof insulator string.

[0005] The upper live lead is supported by a branch pole. Specifically, the branch pole is used to clamp the upper live lead through the pipe clamp structure on the top of the branch pole, and the tail end is fixed to the tower. The branch pole is tilted to support the upper live lead diagonally upward.

[0006] The insulating fork pulley rod is installed on the working layer and an insulating lifting rope is configured. Specifically, the insulating fork pulley rod is fixed to the cross arm of the working layer, and the head of the insulating fork pulley rod extends above the installation position of the windproof insulator string; the insulating lifting rope is tied and wrapped around the winch of the insulating fork pulley rod, and is placed on the lifting wheel at the head of the insulating fork pulley rod and placed downward.

[0007] Connecting the insulating lifting rope to the insulating locking rod specifically involves fixing the open end of the insulating lifting rope to the lifting ring on the head of the insulating locking rod.

[0008] The use of an insulated locking rod to clamp the live lead in the working layer is as follows: the staff holds the insulated locking rod, places the live lead into the locking part between the head of the insulated locking rod and the clamp body, and pulls the head backward to make the head relatively fixed. At this time, the rod is rotated so that it passes through the threaded structure at the front end into the head, so that the clamp body connected to the top front end of the rod is rotated and the head is relative to clamp the live lead.

[0009] Tighten the insulating lifting rope and control the positioning of the live lead by controlling the winch of the insulating fork pulley rod, thereby tightening the insulating lifting rope upward or releasing it downward, so that the insulating lifting rope drives the insulating locking rod and the live lead to adjust to the appropriate position, and then lock this position through the locking device on the winch.

[0010] The specific replacement of the windproof insulator string is to open the bowl head at the bottom of the original windproof insulator string, then use the insulating transfer rope to firmly bind the windproof insulator string, then open the installation point of the windproof insulator string and the tower, and use the insulating transfer rope to transfer the windproof insulator string to the ground; use the insulating transfer rope to transfer the replacement windproof insulator string from the ground to the installation point, and install the windproof insulator string, first install the upper part of the windproof insulator string with the installation point of the tower, and then install the bottom of the windproof insulator string with the bowl head.

[0011] A combination tool for live installation or replacement of wind-proof deflection insulators, characterized in that the combination tool is used to implement the method of any one of claims 1 to 7; comprising an insulating fork-type pulley rod and an insulating locking rod; The insulating fork pulley rod body is provided with a fork-shaped structure at the bottom of the front end, the insulating fork pulley rod body is rotatably mounted with a hanging wheel at the head, and a capstan is rotatably mounted on the tail, and a locking device is provided on the capstan; an insulating lifting rope is wound around the capstan, and the insulating lifting rope passes through the hanging wheel and extends downward; The insulated locking rod includes a head and a rod. The head is a pipe clamp structure. The front end of the rod is inserted into the head through a threaded connection. The top of the front end of the rod is rotatably connected to a clamp body. The clamp body is correspondingly engaged with the head, and a hanging ring is fixedly provided on the outside of the head.

[0012] The locking device includes a positioning hole on the winch and a corresponding positioning hole on the insulating fork pulley rod body, and a positioning pin is inserted between the positioning holes for fixing.

[0013] Also included are feeder poles and insulated righting poles; The branch rod is made of an insulated lock rod with an extension rod fixedly connected to the tail end; The insulating straightening rod is an insulating rod with a disassembly and assembly tool added to the top of the rod for disassembling and assembling the bowl head of the windproof insulator string.

[0014] The working mechanism of this method and combined tool is based on the core logic of insulation isolation, precise positioning and collaborative operation. Through the structural characteristics of each tool component and the coordination of step-by-step actions, the safe replacement of wind-proof insulator strings in a live environment can be achieved. The branch pole clamps the upper live lead through the top pipe clamp structure and is fixed to the tower. The upper lead is supported diagonally upward by the inclined support force to form a safe working space and avoid cross interference with the working layer lead. The insulated fork-type pulley rod serves as the core load-bearing and positioning component. Its fork-shaped structure is fixed to the working layer cross arm. The head hoist wheel and the tail winch form a labor-saving transmission system. The insulated locking rod is connected by an insulated lifting rope to form a mechanical transmission chain of "cross arm fixation-pulley guidance-rope traction". During operation, the insulated locking rod closes the threaded clamp body through the head pipe clamp structure, achieving a rigid clamp on the live lead. The tightening and release of the insulating lifting rope are coordinated with the capstan locking device to complete the suspended positioning of the lead, eliminating the risk of lead shaking during insulator replacement. When replacing insulators, the insulating straightening rod uses the top disassembly tool to precisely operate the bowl head, cooperating with the insulating transfer rope to achieve the safe lowering of the old insulator string and the lifting and alignment of the new string. The entire process progresses through the steps of "isolation-fixation-operation", ensuring that all components work together to complete the replacement of the multi-layer insulator string in an insulated state. This not only meets the safety distance requirements for live working, but also ensures operational accuracy through the rigid constraints of the mechanical structure.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The method and combined tool of the present invention can safely and efficiently install or replace wind-proof insulator strings without power outage, thereby improving the operating space of operators and power supply reliability. The method and combined tool of the present invention can adjust the vertical load and safety distance of the live lead, which not only provides an effective operating space for the operator, but also reasonably controls the live lead, prevents the occurrence of windage failure during operation, and improves the safety of the transmission line.

[0016] The method and combination tool of the present invention form a labor-saving system through the "hanging wheel-capstan" transmission structure of the insulating fork-type pulley rod, reducing the physical exertion of lead wire pulling; the threaded drive clamping method of the insulating locking rod and the special disassembly and assembly tool of the insulating straightening rod realize precise control of lead wire clamping and bowl head operation, reduce repeated adjustment time, and can shorten the working hours of replacing a single set of insulators by more than 30% compared with traditional methods.

It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.

[0020] refer to Figure 1-8 A method for live installation or replacement of a wind-proof insulator comprises the following steps: Use the branch rod 7 to support the upper live lead 2, then install the insulating fork pulley rod 6 on the working layer and configure the insulating lifting rope 61, connect the insulating lifting rope 61 to the insulating locking rod 5, and then use the insulating locking rod 5 to clamp the working layer live lead 2, tighten the insulating lifting rope 61, so as to position and control the live lead 2, and finally replace the windproof insulator string 1.

[0021] Furthermore, the upper live lead 2 is supported by the branch pole 7. Specifically, the branch pole 7 is used to clamp the upper live lead 2 through the pipe clamp structure on the top of the branch pole 7, and the tail end of the branch pole 7 is fixed to the tower 3, so that the branch pole 7 is tilted to support the upper live lead 2 diagonally upward.

[0022] Furthermore, an insulating fork pulley rod 6 is installed on the working layer and an insulating lifting rope 61 is configured. Specifically, the insulating fork pulley rod 6 is fixed to the cross arm 4 of the working layer, and the head of the insulating fork pulley rod 6 extends above the installation position of the windproof insulator string 1; the insulating lifting rope 61 is tied and wound around the winch 63 of the insulating fork pulley rod 6, and is placed on the lifting wheel 62 at the head of the insulating fork pulley rod 6 and placed downward.

[0023] Furthermore, connecting the insulating lifting rope 61 to the insulating locking rod 5 specifically involves fixing the open end of the insulating lifting rope 61 to the lifting ring 54 at the head of the insulating locking rod 5 .

[0024] Furthermore, the insulating locking rod 5 is used to clamp the working layer live lead 2. Specifically, the staff holds the insulating locking rod 5 and places the live lead 2 into the locking part between the head 51 of the insulating locking rod 5 and the clamp body 53. The head 51 is relatively fixed by pulling it backward. At this time, the rod 52 is rotated so that it passes through the head 51 through the threaded structure at the front end, so that the clamp body 53 connected to the top front end of the rod 52 is rotated and engaged with the head 51 to clamp the live lead 2.

[0025] Furthermore, the insulating lifting rope 61 is tightened and the positioning of the live lead 2 is controlled specifically by controlling the winch 63 of the insulating fork-type pulley rod 6, thereby tightening the insulating lifting rope 61 upward or releasing it downward, so that the insulating lifting rope 61 drives the insulating locking rod 5 and the live lead 2 to adjust to a suitable position, and at this time, this position is locked by the locking device on the winch 63.

[0026] Furthermore, the replacement of the windproof insulator string 1 is specifically carried out by opening the bowl head at the bottom of the original windproof insulator string 1, and then using the insulating transfer rope to firmly bind the windproof insulator string 1, and then opening the installation point of the windproof insulator string 1 and the tower 3, and using the insulating transfer rope to transfer the windproof insulator string 1 to the ground; using the insulating transfer rope to transfer the replaced windproof insulator string 1 from the ground to the installation point, and installing the windproof insulator string 1, first install the upper part of the windproof insulator string 1 and the installation point of the tower 3, and then install the bottom of the windproof insulator string 1 and the bowl head.

The head is a pipe clamp structure. The front end of the rod 52 is inserted into the head 52 through a threaded connection. The top of the front end of the rod 52 is rotatably connected to a clamp body 53. The clamp body 53 is correspondingly engaged with the head 51, and a hanging ring 54 is fixedly provided on the outside of the head 51.

[0028] Furthermore, the locking device includes a positioning hole on the winch 63 and a corresponding positioning hole on the rod body of the insulating fork-shaped pulley rod 6, and a positioning pin is inserted between the positioning holes for fixing.

[0029] Furthermore, it also includes a branch pole 7 and an insulating straightening pole; The branch rod 7 is made by fixing the tail end of the insulating lock rod 5 to the extension rod; The insulating straightening rod is an insulating rod with a disassembly and assembly tool added to the top of the rod for disassembling and assembling the bowl head of the windproof insulator string 1.

[0030] The following describes in detail the process of using a method for live installation or replacement of a windproof insulator string 1 in conjunction with a combination tool. First, fix the branch pole 7 to the upper live lead 2 through the pipe clamp structure, and fix the lower end of the branch pole 7 to the iron tower 3, and branch the upper live lead 2 diagonally upward to increase the safety distance from the working layer.

[0031] Then, the fork structure of the insulating fork pulley rod 6 is overlapped on the cross arm 4 of the working layer, and the insulating fork pulley rod 6 is fixed to the cross arm 4, and the insulating lifting rope 61 is wound on the winch 63, and the insulating lifting rope 61 passes through the hanging wheel 62 and extends downward; The insulating lifting rope 61 is lowered to the vicinity of the live lead 2 on the working layer.

[0032] Next, the staff holds the insulating locking rod 5 and places the live lead 2 into the locking part between the head 51 of the insulating locking rod 5 and the clamp body 53. By pulling it backward, the head 51 is relatively fixed under force. At this time, the rod 52 is rotated so that it passes through the head 51 through the threaded structure at the front end, so that the clamp body 53 connected to the top front end of the rod 52 is rotated and engaged with the head 51 to clamp the live lead 2.

[0033] Then, by controlling the winch 63 of the insulating fork pulley rod 6, the insulating lifting rope 61 is tightened upward or released downward, so that the insulating lifting rope 61 drives the insulating locking rod 5 and the live lead 2 to adjust to the appropriate position, and this position is locked by the locking device on the winch 63.

[0034] Next, use the insulating straightening rod to dismantle the bowl head of the windproof insulator string 1, open the bowl head at the bottom of the original windproof insulator string 1, and use the insulating transfer rope to firmly tie the windproof insulator string 1, then open the installation point between the windproof insulator string 1 and the tower 3, and use the insulating transfer rope to transfer the windproof insulator string 1 to the ground.

[0035] Then, use the insulating transfer rope to transfer the replaced windproof insulator string 1 from the ground to the installation point, use the insulating straightening rod to install the bowl head of the new windproof insulator string 1, first install the upper part of the windproof insulator string 1 with the installation point of the tower 3, and then install the bottom of the windproof insulator string 1 with the bowl head to complete the replacement of the windproof insulator string 1.

[0036] Finally, by controlling the rotation of the winch 63 on the insulating fork pulley rod 6, the insulating lifting rope 61 is released, the live lead 2 is lowered to its original position, and the insulating locking rod 5 is removed from the live lead 2, and the live lead 2 is installed back to the lower end of the windproof insulator string 1; the insulating fork pulley rod 6 is removed from the crossarm 4, and the branch line rod 7 is removed from the upper live lead 2 and the tower 3, completing the process of live installation or replacement of the windproof insulator string 1 on this layer.

[0037] Repeat the above steps to complete the replacement of the windproof insulator string 1 of the next layer; it should be noted that there are three layers of cross arms on the tower, and the working space of the top layer is sufficient to directly replace the windproof insulator string 1.
