Description

Technical Field

[0001] This invention relates to the field of live-line working technology, specifically to an electric insulated operating rod for gun-type suspended protection and its construction method. Background Technology

[0002] With the continuous maturation of AI-powered live-line working robots and their nationwide deployment in distribution network maintenance, live-line robot operations have become an important component of live-line work. In live-line robot-assisted lead-wire connection and ground potential connection operations, operators need to perform tasks such as voltage testing, distance measurement, lead wire cutting, lead wire stripping, lead wire fixing, and lead wire splicing. Simultaneously, operators also need to utilize insulated operating rods with different functions to cooperate with the live-line working robot to complete the lead-wire connection operation.

[0003] In actual work, after the lead wire is stripped, in order to prevent the lead wire from swinging and to ensure the safety of the operator, it is necessary to use an insulating hook to fix the lead wire. One end of the insulating hook should be hung on the main line, and the other end should be hung on the lead wire. The operator should hold the bottom of the insulating hook to keep it fixed. Then, the electric insulating operating rod is used to clamp the lead wire and insert it into the wire clamp so that the robot can complete the fire start operation.

[0004] Defects and shortcomings of existing technology: 1. The process of fixing and splicing lead wires is time-consuming and labor-intensive. During live-line work and ground potential connection operations using robots, operators must work independently inside an insulated hopper while wearing protective gear such as cotton gloves, insulating gloves, and puncture-resistant sheepskin gloves. After fixing the lead wire, the operator must hold the bottom of the insulating hook with one hand to prevent it from falling off during connection, and use the other hand to hold an electric insulated operating rod for connection. This electric operating rod is 2.21m long and weighs approximately 4kg. Single-handed operation places excessive demands on the operator's physical strength, easily leading to contact with different potentials and posing significant safety hazards. Furthermore, it is time-consuming, labor-intensive, and reduces work efficiency.

[0005] 2. The large number of insulated operating rods increases the load. Since all three phases of the 10kV line require splicing and securing of the leads, three insulated hooks and an electric insulated operating rod are needed for clamping and releasing the leads. Whether during vehicle operation or inside the insulated hopper, the loading and carrying of these multiple rods increases the load and delays the work, creating inconvenience for emergency repairs.

[0006] In summary, how to design a new electrically insulated operating rod to solve the above problems has become a technical problem that urgently needs to be solved by those in the field. Summary of the Invention

[0007] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to propose an electrically insulated operating rod for a gun-type suspension protection system and its construction method, aiming to achieve the core objectives of simple operation, time and labor saving, and safety and reliability through functional integration, structural innovation, and process optimization.

[0008] To address the aforementioned problems, this invention provides an electrically insulated operating rod for gun-type suspension protection, comprising an electrically insulated operating rod and a suspension unit parallel to and axially slidably connected to one side of the electrically insulated operating rod; the suspension unit includes a locking slide, a hanging rod, a top mounting bracket, and a hook, wherein the locking slide and the top mounting bracket are axially slidably fitted onto the electrically insulated operating rod, and the hanging rod is supported by the locking slide and the top mounting bracket; the locking slide is provided with an adjustment unit to adjust the relative axial position of the hanging rod and the electrically insulated operating rod; a hook is fixed at the top of the hanging rod, and the hook is elastically bent and provided with an anti-disengagement buckle; Preferably, the locking slide includes an arc-shaped rack, a housing, a main gear, a multi-stage transmission gear set, and a handwheel, wherein the arc-shaped rack is fixed on the circumferential outer wall of the electric insulated operating rod; the housing is slidably sleeved on the outside of the electric insulated operating rod and the arc-shaped rack, and the multi-stage transmission gear set is meshed and connected inside the housing. The power input end of the multi-stage transmission gear set is coaxially fixed to the handwheel, and the power output end of the multi-stage transmission gear set is coaxially fixed to the main gear; the spur gear meshes with the arc-shaped rack.

[0009] Preferably, the multi-stage transmission gear set includes a first gear shaft, a second gear shaft, and a third gear shaft, wherein a first gear, a second gear, and a third gear that are sequentially meshed and connected are coaxially fixed on the first gear shaft, the second gear shaft, and the third gear shaft, respectively; the first gear shaft extends outside the housing and is coaxially fixed to a handwheel; and a main gear is also coaxially fixed to the third gear shaft.

[0010] Preferably, a movable plug-in bolt or locking buckle is provided on the top mount to switch the movable / fixed connection between the top mount and the electrically insulated operating rod.

[0011] Preferably, the open end of the hook is set downward, and the inner wall of the hook is fixed with opposing semi-circular structures made of bent elastic metal wire, and the anti-disengagement hook is composed of two opposing semi-circular structures.

[0012] A construction method for an electrically insulated operating rod with a gun-type suspension protection system includes the following steps: S1: The operator adjusts the axial distance between the hook and the electric insulated operating rod at a low ground position to the predetermined position, and the distance between the two is not less than a safe distance of 40cm; S2: The operator holds an electric insulated operating rod and controls the clamp of the electric insulated operating rod to clamp and fix the stripped lead wire. Then, the hook is attached to the pre-construction position on the main line to complete the work of fixing the lead wire within the safe distance of the main line. S3: The operator controls the wiring robot to connect the lead wire and the main wire. During this process, the hook and the clamp at the top of the electric insulated operating rod are used for the orientation positioning of the lead wire. S4: After the lead wire is connected, the operator controls the clamp at the top of the electric insulated operating rod to release it, remove the hook on the main line, and take off the electric insulated operating rod to complete the fire connection operation.

[0013] The electric insulated operating rod and construction method of the present invention for gun-type suspension protection have the following advantages compared with the prior art: 1. This invention integrates the traditional electric insulated operating rod and insulated hook into a single combined rod, which is easy to carry. The single rod can be controlled with both hands to effectively control the lead wire, increasing stability, saving the operator's physical strength, reducing the load compared to the traditional method, avoiding contact with different potentials, and improving safety.

[0014] 2. This invention adopts the "gun-type" working principle, which is quick and simple to operate and improves work efficiency.

[0015] 3. This invention adopts an electric rotating mechanism. After the operator turns on the power switch, he only needs to control the clamp to perform clamping and releasing operations by pressing the on / off button, which improves the efficiency of the operation.

[0016] 4. The clamping jaws of this invention are suitable for all existing wire sizes and can be widely applied to work sites throughout the country.

[0017] 5. By pressing the bar button and sliding the handle forward, the auxiliary rod (i.e. the original insulating hook) can be pushed out. The sliding track is set to 40 cm and is set to a double groove mode to form a locking device. This can quickly complete the fixing of the lead wire and prevent the operating rod from falling off during the fixing process. It also ensures a safe distance between the human body and the live conductor during operation.

[0024] like Figure 1 and Figure 2 As shown, the present invention discloses an electric insulated operating rod for a gun-type suspension protection, comprising an electric insulated operating rod 8 and a suspension unit parallel to and axially slidably connected to one side of the electric insulated operating rod; the suspension unit comprises a locking slide 7, a hanging rod 5, a top hanging seat 4, and a hook 2, wherein the locking slide and the top hanging seat are axially slidably fitted onto the electric insulated operating rod, and the hanging rod is supported by the locking slide and the top hanging seat; the locking slide is provided with an adjustment unit to adjust the relative axial position of the hanging rod and the electric insulated operating rod; a hook is fixed at the top of the hanging rod, and an anti-disengagement buckle 3 is provided in the hook with elastic bending; Preferably, the locking slide includes an arc-shaped rack 6, a housing 17, a main gear 16, a multi-stage transmission gear set, and a handwheel 11. The arc-shaped rack is fixed on the circumferential outer wall of the electric insulated operating rod. The housing is slidably sleeved on the outside of the electric insulated operating rod and the arc-shaped rack. The multi-stage transmission gear set is meshed and connected inside the housing. The power input end of the multi-stage transmission gear set is coaxially fixed to the handwheel, and the power output end of the multi-stage transmission gear set is coaxially fixed to the main gear. The spur gear meshes with the arc-shaped rack.

[0025] Preferably, the multi-stage transmission gear set includes a first gear shaft 12, a second gear shaft 10, and a third gear shaft 9, wherein a first gear 13, a second gear 14, and a third gear 15 that are sequentially meshed and connected are respectively coaxially fixed on the first gear shaft, the second gear shaft, and the third gear shaft; the first gear shaft extends outside the housing and is coaxially fixed to the handwheel; the third gear shaft is also coaxially fixed to the main gear.

[0026] Preferably, a movable plug-in bolt or locking buckle is provided on the top mount to switch the movable / fixed connection between the top mount and the electrically insulated operating rod.

[0027] Preferably, the open end of the hook is set downward, and the inner wall of the hook is fixed with opposing semi-circular structures made of bent elastic metal wire, and the anti-disengagement hook is composed of two opposing semi-circular structures.

[0028] A construction method for an electrically insulated operating rod with a gun-type suspension protection system includes the following steps: S1: The operator adjusts the axial distance between the hook and the electric insulated operating rod at a low ground position to the predetermined position, and the distance between the two is not less than a safe distance of 40cm; S2: The operator holds an electric insulated operating rod and controls the clamp 1 of the electric insulated operating rod to clamp and fix the stripped lead wire. Then, the hook is attached to the pre-construction position on the main line to complete the work of fixing the lead wire within the safe distance of the main line. S3: The operator controls the wiring robot to connect the lead wire and the main wire. During this process, the hook and the clamp at the top of the electric insulated operating rod are used for the orientation positioning of the lead wire. S4: After the lead wire is connected, the operator controls the clamp at the top of the electric insulated operating rod to release it, remove the hook on the main line, and take off the electric insulated operating rod to complete the fire connection operation.

[0029] To more clearly illustrate the specific embodiments of the present invention, an example is provided below: 1. Component assembly and initial state First, assemble the suspension unit onto the electrically insulated operating rod 8. The suspension unit includes a locking slide 7, a hanging rod 5, a top mounting bracket 4, and a hook 2. During installation, sequentially insert the sliding sleeves of the top mounting bracket 4 and the locking slide 7 onto the rod body of the electrically insulated operating rod 8, ensuring they can slide axially along the rod body. Then, fix the upper and lower ends of the hanging rod 5 to the lateral connecting parts of the top mounting bracket 4 and the locking slide 7, respectively, so that the hanging rod 5 is parallel to the electrically insulated operating rod 8. Finally, fix the hook 2 with the anti-disengagement buckle 3 to the top of the hanging rod 5. In the initial state, by rotating the handwheel 11, the gear mechanism inside the locking slide 7 can be driven, allowing the entire suspension unit to slide close to the top clamp 1 of the electrically insulated operating rod 8, thus shortening the overall length for easier carrying and transportation.

[0030] 2. On-site operation process After the workers arrive at the site, the specific operating procedures are as follows: Step 1: Presetting the Safety Distance. The operator operates from the ground or inside the insulated bucket of the insulated boom truck, at a low position. The operator rotates the handwheel 11, mounted clockwise or counterclockwise on the outside of the locking slide 7 housing. The handwheel 11 drives the first gear shaft 12 and its first gear 13 to rotate. The first gear 13 drives the second gear 14, which in turn drives the third gear 15 via the second gear shaft 10. Finally, the third gear shaft 9, coaxial with the third gear 15, drives the main gear 16 to rotate. Since the main gear 16 meshes with the arc-shaped rack 6 fixed to the operating lever, the rotational motion of the gear is converted into linear motion of the housing 17 along the arc-shaped rack 6 (i.e., along the axial direction of the operating lever). The operator slides the suspension unit downwards until the axial distance between the hook 2 and the top clamp 1 is not less than a safe distance of 40 cm. At this point, the meshing of the gear and rack has a self-locking characteristic, effectively preventing the suspension unit from accidentally sliding under gravity or operational vibration, thus forming a reliable lock.

[0031] Step Two: Lead Wire Fixing and Tool Suspension. The operator holds the handle of the electric insulated operating rod 8 with both hands, first using the button on the handle to control the electric clamp 1 at the top to hold the stripped lead wire. Then, the operating rod is raised, so that the hook 2 at the top of the suspension unit is attached to the preset construction position on the main line. The anti-dislodgement buckle 3 made of elastic metal wire inside the hook 2, with its two semi-circular structures providing opposing elastic support, prevents the hook from accidentally falling off the main line. At this point, the operating rod is suspended from the main line via the hook 2, and the lead wire is reliably held by the clamp 1. The operator can temporarily release their hands; the operating rod achieves automatic fixing and positioning of the lead wire.

[0032] Step 3: Robot splicing operation. After the control lever is stably suspended and the lead wire is fixed, the operator can free their hands and operate the live-line working robot to perform subsequent splicing operations (e.g., threading the lead wire through the clamp and tightening it). During this process, hook 2 and clamp 1 work together to ensure the spatial posture stability of the lead wire relative to the main guide line, providing good conditions for the robot to operate accurately.

[0033] Step Four: Work Completion and Tool Retrieval. After the robot completes the lead wire connection, the operator once again holds the control lever handle with both hands. First, control the electric clamp 1 to release the lead wire. Then, slightly lift the control lever upwards to allow the hook 2 to overcome the elastic force of the anti-disengagement buckle 3 and detach from the main guide wire. Finally, turn the handwheel 11 in the opposite direction to slide the suspension unit back to its initial position near the clamp 1, thus retracting the entire control lever for future use or storage.

[0034] The working principle of this invention is as follows: The core working principle of this invention lies in functional integration and mechanical locking positioning, and its working process is based on the following two main mechanisms: 1. "Gun-type" telescopic and locking mechanism: This device creatively integrates the function of the insulating hook into a suspension unit that can slide along the main operating rod axis. Its adjustment mechanism simulates the push-pull and locking principle of a "gun". By rotating the handwheel, through a multi-stage gear set, the gear meshing with the fixed rack is finally driven, achieving smooth and precise linear movement of the suspension unit. Once it slides to the predetermined position (such as a 40cm safety distance), due to the self-locking characteristics of the gear and rack transmission pair (especially when using helical gears or a sufficient friction angle), the position is reliably locked, and the suspension unit will not move unless torque is manually applied to the handwheel. This "push-pull lock" method is intuitive and quick to operate, and ensures absolute stability during operation, hence the name "gun-type".

[0035] 2. Cooperative Working Mechanism of Electric Clamping and Anti-detachment Hook: After the suspension unit is precisely positioned and locked, the device enters the working state. The top electric clamp is driven by a built-in power supply and its opening and closing are controlled by a button on the handle to clamp or release the lead wire, replacing laborious and inaccurate manual operation. Simultaneously, the hook at the top of the suspension unit is designed with an inwardly elastically bent anti-detachment buckle. When it hooks onto the main guide line, the anti-detachment buckle elastically deforms and rebounds, forming a barrier to prevent detachment. In this way, the electric clamp is responsible for gripping and releasing the lead wire, while the anti-detachment hook reliably anchors the entire tool body to the main guide line. The two work together, allowing the operating lever to autonomously and stably complete the task of fixing the lead wire without continuous manual gripping, thus freeing the operator's hands to perform more precise or important control tasks, greatly improving safety and efficiency.

[0036] In addition, the electric insulated operating rod of the present invention preferably adopts a mature product in the prior art.

[0037] Finally, any aspects not fully described in this invention utilize existing mature products and technologies.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
