Description

Technical Field

[0001] The present invention relates to the field of live-line operation in distribution networks, and in particular to a distribution network lead positioning tool. Background Art

[0002] When performing ground potential connection operations on overhead lines in distribution networks, operators need to hold an insulated operating rod to lift the connection tool and the lead wire to be connected to a high main line connection point and perform the connection operation. Since the operating procedures require that the reserved length of the lead wire to be connected is generally not large, the lead wire is prone to generate large tension during the lifting process, resulting in human power being unable to lift the lead wire to the required height, thus causing the connection operation to fail. In addition, the increasing power load has increased the wire diameter and weight of the lead wire to be connected, and the influence of the tension generated when the conductor is lifted has become more and more obvious, further increasing the difficulty of the connection operation.

[0003] Patent application number CN202110559009.6 discloses a lead-wire fixing device for power distribution network operations. The device includes a base with an electric lifter mounted on it. This device uses the electric lifter to replace manual lifting, which reduces the difficulty of connecting the power supply to a certain extent. However, the base must be fixed to the foundation or other supporting objects during use, which is inconvenient in some operation scenarios. Patent application number CN202010839973.X discloses an assembled lead-wire support specifically for live-line working robots. The support comprises an insulating cross-arm, a rotating connector, an insulating support rod, and a lead-wire clamp. The insulating cross-arm is mounted on a utility pole, and the rotating connector connects the insulating support rod to the insulating cross-arm. The lead-wire clamp is mounted on the upper end of the insulating support rod. This lead-wire support is adaptable to different contact heights and contact points, but requires the insulating cross-arm to be secured to the pole before use, which limits its use and is time-consuming. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a distribution network lead positioning tool, which can lift the lead to the ignition point through an electric lifting mechanism, reducing the difficulty of the ignition operation. The tool is easy to operate and can adapt to different operation scenarios.

[0005] A distribution network lead positioning tool comprises a positioning unit and an assembly unit; the positioning unit comprises a guide rod, a clamp arranged at the upper end of the guide rod, a positioning base movably engaged with the guide rod, and a power mechanism driving the positioning base to move axially along the guide rod; the assembly mechanism comprises a support rod, a parallel groove wire clamp arranged at the upper end of the support rod, and a connecting piece fixed to the side of the support rod, wherein the connecting piece can form a detachable connection with the positioning base.

[0006] When the present invention is in use, the clamp at the upper end of the guide rod is clamped in the side area of ​​the wire connection point, so that the guide rod is in a vertical fixed state, and the positioning base is returned to a position close to the lower end of the guide rod, and the lead to be connected is fixed on the parallel groove wire clamp at the upper end of the support rod, and the support rod is connected to the positioning base through a connecting piece, so that the vertical position of the parallel groove wire clamp corresponds to the wire connection point, and then the power mechanism is activated to move the positioning base upward along the guide rod, and the support rod and the parallel groove wire clamp move synchronously with the positioning base, and the parallel groove wire clamp gradually approaches the wire connection point upward. After reaching the wire connection point, the power mechanism stops operating, and subsequently the wire and the lead to be connected can be connected through the parallel groove wire clamp to realize the ground potential connection operation. In order to achieve stable lifting and positioning of the lead, a fixed support structure is usually required as the basis for lifting the lead. For example, in the patent document with application number CN202110559009.6, when an electric lifting pole is used, a stable foundation is required to place the base of the electric lifting pole. In the patent document with application number CN202010839973.X, the insulating crossarm needs to be fixed on the electric pole to achieve the positioning of the insulating support pole and the lead clamp. The common point of these schemes is that a support point outside the overhead wire needs to be found for construction, which causes the construction process to be restricted by the geographical environment and cannot generally meet the needs of fire connection operations in various situations. The present invention has made a breakthrough in placing the support point on the overhead wire to be operated, and the positioning unit can be fixed on the side of the fire connection point of the overhead wire. The installation of the positioning unit is almost unaffected by the geographical environment.

[0007] Furthermore, the power mechanism includes a motor and a transmission assembly driven by the motor, the transmission assembly includes a transmission rod rotatable about an axis and connected to the motor, a winch coaxially fixedly connected to the transmission rod, and a pull rope pulled by the winch, the axis of the transmission rod and the axis of the guide rod are perpendicular to each other, and the pull rope is connected to the positioning base.

[0008] In common transmission systems, the mechanisms that control the directional movement of objects usually include pneumatic rod mechanisms, screw mechanisms, and traction rope mechanisms. In the application scenario of the present invention, since the installation and fixation of the positioning unit requires manual hand-holding, in order to improve the maneuverability of the positioning unit, the positioning unit needs to be lighter. Therefore, the present invention preferably uses a lighter pull rope to pull the positioning base to move, and the positioning base has a larger range of movement when moved by pulling the pull rope, which can better meet construction needs.

[0009] Furthermore, the positioning base is provided with a pulley assembly, the first end of the pull rope is connected to the winch and is pulled by the winch, the second end of the pull rope is connected to a fixed end plate, the fixed end plate is relatively fixed to the guide rod, and the middle part of the pull rope cooperates with the pulley assembly.

[0010] Compared with the solution of directly using a pull rope for traction, setting up a pulley assembly can reduce the traction force required for the pull rope, making it easier to lift the lead wires with larger wire diameters and weights. It also reduces the power requirements of the motor and reduces the equipment cost.

[0011] Furthermore, the pulley assembly includes a first longitudinal pulley, a second longitudinal pulley, a first transverse pulley and a second transverse pulley, the axes of the first longitudinal pulley and the second longitudinal pulley are perpendicular to the guide rod, the axes of the first transverse pulley and the second transverse pulley are parallel to the guide rod, the first longitudinal pulley and the second longitudinal pulley are coaxially spaced apart, the first transverse pulley and the second transverse pulley are arranged between the first longitudinal pulley and the second longitudinal pulley and deviate from the axes of the first longitudinal pulley and the second longitudinal pulley, and the pull rope is overlapped with the first longitudinal pulley, the first transverse pulley, the second transverse pulley and the second longitudinal pulley in sequence.

[0012] Furthermore, the positioning base includes a main body portion that is slidably connected to the guide rod and a hanging portion arranged on the side of the main body portion, and the hanging portion has a positioning hanging hole; the connecting member includes a connecting hook that can be plugged into and matched with the positioning hanging hole.

[0013] Furthermore, the positioning base includes an upper clamping block, a positioning clamping plate and a lower clamping block that are stacked and fixedly connected in sequence, and the portion of the positioning clamping plate close to the edge extends outward relative to the upper clamping block and the lower clamping block to form the suspension portion, and the pulley assembly is positioned and connected to the upper clamping block.

[0014] Furthermore, the positioning hanging hole has a plurality of mating sites distributed in the circumferential direction of the guide rod, and the hook is selectively connected to the hanging part through any of the mating sites, and at least a part of the mating sites are connected to each other and allow the hook to slide between different mating sites that are connected to each other.

[0015] Furthermore, the connecting member also includes a mounting base; the mounting base includes an upper locking block, a mounting splint and a lower locking block stacked in sequence, the upper locking block and the lower locking block are both fixedly connected to the support rod, the upper and lower sides of the mounting splint are fixedly abutted against the upper locking block and the lower locking block respectively, a part of the mounting splint extends outward relative to the support rod and forms a mounting platform, and the connecting hook is fixedly connected to the mounting platform.

[0016] Furthermore, the connecting member further includes an insulating mounting block, the insulating mounting block is fixedly connected to the mounting platform, and the connecting hook is fixedly connected to the insulating mounting block.

[0017] Furthermore, a limiting protrusion ring extending around the support rod is provided on the side of the lower locking block close to the mounting clamp, and a matching hole that can cooperate with the outer wall of the limiting protrusion ring is provided in the middle of the mounting clamp, and the protruding height of the limiting protrusion ring does not exceed the thickness of the mounting clamp.

[0018] Furthermore, the positioning unit is provided with an electric control module for controlling the clamp and the power mechanism, and the distribution network lead positioning tool also includes a controller that can send signals to the electric control module.

[0019] The application of the present invention can achieve the following beneficial effects: 1. When the present invention is used, the overhead wire to be connected is used as the supporting base, the positioning unit is fixedly connected to the overhead guide, and then the power mechanism and positioning base of the positioning unit are used to position and lift the assembly unit, and the lead to be connected is lifted to the connection position of the overhead wire. During the entire operation, the operation object only includes the overhead wire, and there is no need to find support points other than the overhead wire. Therefore, the present invention is significantly less affected by terrain factors during the operation process, has better versatility, and can cope with a variety of different operation scenarios.

[0020] 2. The present invention is easy to use and has high operating efficiency. During use, it is only necessary to fix the clamp on the side area of ​​the overhead wire connection point, and then connect the assembly unit carrying the lead to be connected with the positioning base, and then the positioning and lifting of the lead to be connected can be started. The operation steps are relatively few and the operation difficulty is low.

[0021] 3. In some embodiments of the present invention, the power mechanism uses a lightweight pull rope to pull the movement of the positioning base, so that the weight of the positioning unit is lower and the maneuverability of the positioning unit is improved. In a preferred embodiment, the pull rope is connected to the positioning base through a pulley assembly, which improves the stability during the traction process and reduces the traction force requirement of the pull rope, making it easier to lift the lead wires with larger wire diameters and weights. At the same time, it also reduces the power requirements of the motor, thereby reducing the equipment cost.

[0022] 4. In some embodiments of the present invention, the positioning hanging hole has a plurality of mating sites distributed in the circumferential direction of the guide rod, and at least a part of the mating sites are connected to each other and allow the hook to slide between different mating sites that are connected to each other. After the assembly unit is connected to the positioning unit through the hook, the assembly unit can move circumferentially around the positioning unit, thereby controlling the horizontal position of the parallel groove wire clamp at the upper end of the support rod, thereby facilitating the connection between the parallel groove wire clamp and the overhead wire.
