Description

Technical field:

[0002] The invention relates to a hanging and removing device for overhead line live wire repair equipment and a working method thereof. Background technology:

[0004] With the development of electricity, the overhead lines in cities have also achieved a high insulation rate. Since the insulated wires are operated in an open-air environment, the insulation of the insulated wires is prone to damage as the operating time increases. When the insulated wires are damaged, the charged metal will be exposed. If foreign objects such as branches and plastic bags fall, it is easy to cause short circuit tripping, and serious power outages will cause large-scale power outages. Therefore, it is necessary to inspect the processing lines and repair the damage.

[0005] The existing live repair method requires the use of an insulated boom truck to transport the repair equipment upward to the overhead line. The lifting method of the repair equipment requires the use of professional insulated boom trucks, tools and personnel, and has strict requirements on the surrounding environment of the line. For places where the insulated boom truck cannot enter, the repair equipment cannot be easily hung on the live wires of the overhead line, which has great limitations and poor flexibility. Summary of the invention:

[0007] The present invention makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a hanging and dismantling device for overhead line live wire repair equipment and a working method thereof, which has a reasonable design, is convenient for hanging and dismantling the repair equipment, and has good flexibility in use.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a hanging and disassembling device for overhead line live wire repair equipment, including a pair of hooks for fixed installation at both ends of the object to be hoisted, a hook with a hook head facing downward is provided above each hook, the hook is driven to rise and fall by a lifting mechanism and is used to hook on the overhead line live wire, a lifting pulley is installed at the lower end of the hook, a vertically arranged lifting rope is wound around the lifting pulley, and the lifting rope is provided with a clamping member for clamping on the upper end of the hook from bottom to top and driving the hook to rise and fall.

[0009] Furthermore, the hook is in a Y shape, and the two forked arms at the upper end of the hook are bent downward to form a hook portion with the hook head facing downward, and a V-shaped rope threading recess is formed between the two forked arms at the upper end of the hook to facilitate the vertical passage of the lifting rope; the clamping piece is clamped at the lower end of the hook portion from bottom to top.

[0010] Furthermore, a support plate is fixedly connected to the bottom of the hook, and mounting holes for connecting to the object to be hoisted via locking bolts are provided at both ends of the support plate.

[0011] Furthermore, both ends of the sling rope are fixedly connected to the clamping piece, and the clamping piece and the sling rope form a closed ring structure.

[0012] Furthermore, the clamping piece is in a spherical shape.

[0013] Furthermore, the lower end of the hook is fixedly connected with a mounting seat plate, the lifting pulley is located below the mounting seat plate, and the upper end of the pulley bracket of the lifting pulley is rotatably connected to the mounting seat plate through a bearing.

[0014] Furthermore, the lifting mechanism includes a drone, and a hook for hooking the upper end of the hook is fixedly connected to the bottom of the drone.

[0015] Furthermore, a pair of hooks are fixedly mounted at both ends of the length direction of the object to be hoisted, and the rope threading recesses of the pair of hooks are arranged opposite to each other.

[0016] In order to achieve the above object, another technical solution adopted by the present invention is: a working method of a hanging and removing device of an overhead line live wire repair device, comprising the following steps:

[0017] Step S1: a pair of hooks are fixedly installed at both ends of the length direction of the object to be hoisted, and the rope threading notches of the pair of hooks are arranged opposite to each other;

[0018] Step S2: hook the hook at the bottom of the drone onto the upper end of one of the hooks, start the drone, and use the drone to transport the hook upward to a live wire on the overhead line; then the drone returns, hooks the hook at the bottom of the drone onto the upper end of another hook, and the drone is started again to transport the hook upward to a live wire on the overhead line;

[0019] Step S3: Pull the ropes on both sides toward the rope threading notch in sequence, so that one side of the rope extends into the rope threading notch, and then pull the other side of the rope downward, so that the clamping piece on the rope is clamped from bottom to top at the lower end of the clamping hook portion of the clamping hook;

[0020] Step S4: Pull the lifting ropes connected to the lifting pulleys at the lower ends of the hooks on both sides at the same time, the lifting ropes rotate around the lifting pulleys and drive the clamping parts to move upward, and the clamping parts on both sides pull the objects to be lifted upward through the clamping hooks, thereby driving the objects to be lifted to rise;

[0021] Step S5: When the object to be hoisted is hoisted upwards and connected to the live wire of the overhead line, the hoisting rope is pulled toward the opening direction of the rope threading recess to separate the clamping piece on the hoisting rope from the clamping hook part, thereby completing the hoisting of the object to be hoisted;

[0022] Step S6: Start the drone, move the drone to the side of the live wire of the overhead line, hook the upper end of one of the hooks with the hook at the bottom of the drone, and transport the hook downward to the ground; then the drone returns, and the hook at the bottom of the drone hooks the upper end of another hook, and also transports the hook downward to the ground;

[0023] Step S7: when it is necessary to remove the object to be hoisted from the live wire of the overhead line, repeat step S2, hoist the hooks on both sides until the hooks are set on the live wire of the overhead line, then pull the lifting rope toward the rope threading notch, so that one side of the lifting rope extends into the rope threading notch, and then pull the other side of the lifting rope downward, so that the clamping piece on the lifting rope is clamped from bottom to top at the lower end of the clamping hook portion of the clamping hook;

[0024] Step S8: When the object to be hoisted is disconnected from the live wire of the overhead line, the hoisting rope is slowly released, the hoisting rope rotates around the hoisting pulley and drives the clamping member to move downward, and the clamping members on both sides pull the object to be hoisted downward through the hooks, thereby driving the object to be hoisted to descend;

[0025] Step S9: When the object to be hoisted is lowered to the ground, pull the lifting rope toward the opening direction of the rope threading recess to separate the clamping part on the lifting rope from the clamping hook part, thereby completing the disassembly of the object to be hoisted, and then repeat step S6 to remove the hook from the live wire of the overhead line.

[0026] Compared with the prior art, the present invention has the following effects: the present invention is reasonably designed, and can hang and remove the repair equipment on the live wire of the overhead line without using an insulating boom truck. It has good flexibility in use and can adapt to various line surrounding environments. Description of the drawings:

Specific implementation method:

[0041] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] like Figures 1 to 10As shown, a hanging and disassembling device of an overhead line live wire repair device of the present invention comprises a pair of hooks 2 for being fixedly installed at both ends of an object to be hoisted 1, a hook 3 with a hook head facing downward is arranged above each hook 2, the hook 3 is driven to rise and fall by a lifting mechanism and is used to be hooked on the live wire 4 of the overhead line, a hoisting pulley 5 is arranged at the lower end of the hook 3, a vertically arranged hoisting rope 6 is wound around the hoisting pulley 5, and a clamping member 7 is arranged on the hoisting rope 6 for clamping on the upper end of the hook 2 from bottom to top and driving the hook 2 to rise and fall. When in use, the hook 3 is driven by the lifting mechanism to move upward from the ground to be hooked on the live wire 4 of the overhead line, and then the hook 3 is pulled by the hoisting rope 6 to move along the live wire, so that the clamping member 7 on the hoisting rope 6 is clamped with the upper end of the hook 2, and then the hoisting rope 6 is pulled downward away from the side of the clamping member 7, the hoisting rope 6 drives the clamping member 7 to move upward, and the clamping member 7 pulls the object to be hoisted 1 upward through the hook 2 to realize the hoisting operation.

[0044] In this embodiment, the hook 2 is in a Y shape, and the two bifurcated arms at the upper end of the hook 2 are bent downward to form a hook portion 201 with the hook head facing downward, and a V-shaped rope threading recess 202 is formed between the two bifurcated arms at the upper end of the hook 2 to facilitate the rope 6 to pass through vertically; the clamping member 7 is clamped at the lower end of the hook portion 201 from bottom to top. Since the hook is in a Y shape, when the rope is moved, it is convenient to move the rope into the rope threading recess of the hook or move it out of the rope threading recess, thereby driving the clamping member to be engaged with or separated from the hook portion. Preferably, the two bifurcated arms at the upper end of the hook are in an arc shape.

[0045] In this embodiment, a rectangular support plate 203 is also fixedly connected to the bottom of the hook 2, and mounting holes are provided at both ends of the support plate 203. The support plate 203 is connected to the object to be hoisted 1 through locking bolts passing through the mounting holes. Preferably, a pair of hooks are fixedly installed at both ends of the length direction of the object to be hoisted, and the rope threading notches of the pair of hooks are arranged opposite to each other.

[0046] In this embodiment, both ends of the suspension rope 6 are fixedly connected to the clamping member 7, and the clamping member 7 and the suspension rope 6 form a closed ring structure. The suspension rope 6 of the ring structure is connected to the lifting pulley 5, and the clamping member 7 is located on one vertical side of the suspension rope 6. By pulling the other vertical side of the suspension rope 6 up and down, the clamping member 7 can be driven to move up and down. Preferably, the suspension rope is an insulating rope.

[0047] In this embodiment, the clamping member 7 is a ball-shaped structure, and preferably, the clamping member is a steel ball.

[0048] In this embodiment, the lower end of the hook 3 is fixedly connected to the mounting seat plate 8, and the lifting pulley 5 is located below the mounting seat plate 8. The upper end of the pulley bracket 9 of the lifting pulley 5 is rotatably connected to the mounting seat plate 8 through a bearing so that the entire lifting pulley can rotate 360°.

[0049] In this embodiment, the lifting mechanism includes a drone 10, and the bottom of the drone 10 is fixedly connected with a hook 11 for hooking the upper end of the hook 3, and the hook head of the hook 11 faces upward. During use, the upper end of the hook 3 is hooked by the hook 11, and then the drone 10 pulls the hook 3 to move upward. It should be noted that the drone is an existing mature product and can be purchased directly, and its structure is not described in detail here. When in use, the drone hooks the upper end of the hook through the hook, and then the drone pulls the hook to move upward. When the hook is located next to the live wire of the overhead line, the drone moves longitudinally so that the hook head is located directly above the live wire of the overhead line. Then the drone drives the hook to move downward so that the hook is hooked on the live wire of the overhead line. Finally, the drone moves horizontally to separate the hook from the hook.

[0050] In this embodiment, the object to be hoisted is a patching machine, which includes a walking mechanism 12, a sleeve mechanism, a crimping mechanism, a slide mechanism and a camera mechanism respectively connected to a controller. The walking mechanism is used to limit the movement of the patching machine body on the overhead line. The walking mechanism includes a pair of moving wheel mechanisms arranged on both sides of the sleeve mechanism; the moving wheel circumference of the moving wheel mechanism is provided with an inclined groove and driven by a motor. The walking mechanism also includes a flipping mechanism connected to the moving wheel mechanism, and the flipping mechanism is hinged with the bracket of the patching machine body, driven by a motor and provided with a locking mechanism. When the patching machine is hoisted to a certain height from the live wire of the overhead line, the flipping mechanism controls the moving wheel to swing upward to the live wire of the overhead line.

[0051] Specific implementation process: Taking the object to be hoisted 1 as a repair machine as an example, the work includes the following steps:

[0052] Step S1: A pair of hooks 2 are fixedly mounted at both ends of the repair machine in the length direction, and the rope threading recesses 202 of the pair of hooks 2 are arranged opposite to each other;

[0053] Step S2: hook the hook 11 at the bottom of the drone 10 to the upper end of one of the hooks 3, start the drone 10, and use the drone 10 to transport the hook 3 upward to the live wire 4 of the overhead line; then the drone 10 returns to the ground, hook the hook 11 at the bottom of the drone 10 to the upper end of another hook 3, and start the drone 10 again to transport the hook 3 upward to the live wire 4 of the overhead line. Figure 6 As shown;

[0054] Step S3: Pull the ropes 6 on both sides of the repair machine toward the rope threading notch 202 in sequence, so that one side of the rope 6 with the clamping piece 7 extends into the rope threading notch 202, and the clamping piece 7 is kept at the lower side of the clamping hook portion 201 of the hook 2. Then, pull the other side of the rope 6 downward, so that the clamping piece 7 on the rope 6 is clamped at the lower end of the clamping hook portion 201 of the hook 2 from bottom to top, as shown in FIG. Figure 7 As shown;

[0055] Step S4: Pull the lifting ropes 6 connected to the lifting pulleys 5 at the lower ends of the hooks 3 on both sides at the same time, the lifting ropes 6 rotate around the lifting pulleys 5 and drive the clamping members 7 to move upward, and the clamping members 7 on both sides pull the repair machine upward through the hooks 2 to drive the repair machine to rise. Figure 8 As shown; it should be noted that the pulling of the sling can be achieved by manpower or by other winding equipment;

[0056] Step S5: When the machine to be repaired is hoisted upwards and its traveling mechanism 12 is connected to the live wire 4 of the overhead line, the side of the lifting rope 6 with the clamping member 7 is first pulled downwards to separate the clamping member 7 from the clamping hook portion 201 vertically, and then the lifting rope 6 is pulled toward the opening direction of the rope threading recess 202 to separate the clamping member 7 from the clamping hook portion 201 horizontally, thus completing the hoisting of the machine to be repaired. Fig. 9 , 10 As shown;

[0057] Step S6: The drone 10 is started, and the drone 10 moves to the side of the live wire 4 of the overhead line, and hooks the upper end of one of the hooks 3 through the hook 11 at the bottom of the drone 10, and the hook 3 is transported downward to the ground; then the drone 10 returns, and the hook 11 at the bottom of the drone 10 hooks the upper end of another hook 3, and the hook 3 is also transported downward to the ground;

[0058] Step S7: When the repair machine needs to be removed from the live wire 4 of the overhead line, step S2 is repeated to hoist the hooks 3 on both sides to the live wire 4 of the overhead line, and then the lifting rope 6 is pulled toward the rope threading recess 202 so that one side of the lifting rope 6 extends into the rope threading recess 202, and then the other side of the lifting rope 6 is pulled downward so that the clamping member 7 on the lifting rope 6 is clamped from bottom to top at the lower end of the clamping hook portion 201 of the clamping hook 2;

[0059] Step S8: When the repair machine is disconnected from the live wire 4 of the overhead line, the lifting rope 6 is slowly released, the lifting rope 6 rotates around the lifting pulley 5 and drives the clamping member 7 to move downward, and the clamping members 7 on both sides pull the repair machine downward through the hook 2, thereby driving the repair machine to descend;

[0060] Step S9: When the repair machine is lowered to the ground, pull the suspension rope 6 toward the opening direction of the rope threading recess 202 to separate the clamping member 7 on the suspension rope 6 from the clamping hook portion 201, completing the disassembly of the repair machine, and then repeat step S6 to remove the hook from the live wire of the overhead line.

[0061] The advantages of the present invention are: (1) the repair equipment can be hung and removed on the live wire of the overhead line without using an insulated boom truck, which not only reduces the repair cost but also has good flexibility in use and can adapt to various line surrounding environments; (2) by designing the hook into a Y shape, it is not only convenient to firmly clamp the clamping piece and the hook to ensure stable lifting, but also easy to quickly separate the clamping piece from the hook, thereby improving the convenience of operation.

[0062] It should be noted that the present invention is not limited to hoisting the object to be hoisted onto the live wire of the overhead line, but can also be applied to hoisting in other places.

[0063] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integrated molding using a casting process) (except when it is obviously impossible to use an integrated molding process).

[0064] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the present invention include states or shapes that are approximate, similar, or close to them.

[0065] Any component provided by the present invention may be assembled from a plurality of separate components, or may be a separate component manufactured by an integral forming process.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
