[0003] Insulators are commonly used accessories in power systems. With the operation of power systems, a large number of insulators that do not meet usage requirements are dismantled. Among them, the polymer materials, glass fibers and metal components in composite insulators can be recycled and reused. The metal materials and waste porcelain pieces in porcelain insulators can also be recycled and reused. During the recycling period, porcelain insulators are generally hammered to break the porcelain sheds, thereby separating the metal core rod and the porcelain shed. This recycling method will produce a large number of porcelain pieces. The sharp edges of the porcelain pieces can easily cause harm to the staff, and during the hammering, the flying porcelain pieces can also easily cause personal injury. Summary of the invention

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides a porcelain insulator recovery device and a working method, which take into account the structural characteristics of porcelain insulators, and use a loading unit to send the porcelain insulators to be recovered one by one to the disassembly workbench and place them in a "C"-shaped support, and use the pneumatic hammer of the disassembly machine to hammer one end of the core rod of the insulator, so that the porcelain shed part of the insulator is broken by the shearing action of the C-shaped support, and the metal core rod falls into the discharging slide rail from the hollow part of the C-shaped support, thereby realizing the separation of the metal core rod and the porcelain shed fragments. The device can be operated in an automated manner without manual participation, thereby reducing the possible personal injury caused by porcelain pieces.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A first aspect of the present invention provides a porcelain insulator recovery device, comprising:

[0007] A loading unit, used to receive the insulators to be recycled and transport the insulators to the disassembly workbench;

[0008] The disassembling unit comprises a disassembling machine and a disassembling workbench. A C-shaped support is arranged on the disassembling workbench. The metal end of the insulator is hammered by the pneumatic hammer of the disassembling machine. The porcelain shed is broken and separated from the metal core rod under the shearing action of the C-shaped support. The broken porcelain pieces are recovered and stored by the discharging unit, and the separated metal core rod falls into the space below the hollow part of the C-shaped support for collection.

[0009] Furthermore, the loading unit has a conveying plane for driving the insulators, and a fixed groove is provided at a set position of the conveying plane. One side of the fixed groove faces the disassembly workbench, and the other side is provided with a transverse push plate driven by a transverse cylinder.

[0010] Furthermore, the conveying plane has a strip-shaped groove for accommodating a metal head at one end of the insulator, and the metal core rods of the insulators in the conveying plane are arranged in a vertical direction.

[0011] Furthermore, a fixed groove is provided at the setting position of the strip groove, and the fixed groove is used to accommodate the lower half of the insulator, and the fixed groove is connected to the disassembly unit through a loading slide rail.

[0012] Furthermore, the transverse push plate is arc-shaped, and the curvature of the arc matches the diameter of the insulator.

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0039] Porcelain insulators and composite insulators are both commonly used components in high-voltage equipment, with different advantages and disadvantages, such as:

[0040] Porcelain insulator: usually made of electrical ceramics, with stable chemical properties, high resistivity and high dielectric strength. Its structure is generally composed of two hemispherical mother-and-child sleeves and end metals, and the surface is often covered with porcelain glaze to increase surface smoothness and waterproof wettability, and improve mechanical strength. However, in contrast, porcelain insulators are heavy, inconvenient to construct, and may explode and produce cracked porcelain pieces under certain extreme working conditions.

[0041] Composite insulator: mainly composed of one or more insulator core rods, sleeves and end metal parts. The core rod is generally made of epoxy glass fiber, the sleeve and shed are mostly made of synthetic materials such as silicone rubber, and the connecting parts at both ends are usually metal. This structure makes the composite insulator have both excellent electrical properties and certain mechanical strength. Unlike porcelain insulators, composite insulators are generally manufactured in a whole string to make up for their relatively weaker radial stress bearing capacity. In addition, since composite insulators use a large amount of rubber materials, they are prone to aging and may cause thermal degradation and bubble problems.

[0042] The two types of insulators differ in materials, structures and performances, so the recycling processes used during recycling are also different. As introduced in the background technology, porcelain insulators generally use hammering to break the porcelain shed, thereby separating the metal core rod and the porcelain shed. This recycling method will produce a large number of broken porcelain pieces. The sharp edges of the porcelain pieces can easily cause harm to the staff, and during the hammering, the flying porcelain pieces can also easily cause personal injury.

[0043] Therefore, the following embodiments provide a porcelain insulator recovery device and a working method, taking into account the structural characteristics of the porcelain insulator, using a loading unit to feed the porcelain insulators to be recovered one by one to the disassembly workbench and place them in a "C"-shaped support, using a pneumatic hammer of a disassembly machine to hammer one end of the core rod of the insulator, so that the porcelain shed part of the insulator is sheared by the C-shaped support and broken, and the metal core rod falls from the hollow part of the C-shaped support into the discharge slide rail, thereby realizing the separation of the metal core rod and the porcelain shed fragments. The device can be operated in an automated manner without manual intervention, thereby reducing possible personal injury caused by porcelain pieces.

[0044] Embodiment 1:

[0045] like Figure 1 As shown, the porcelain insulator recovery device comprises:

[0046] A loading unit 2 is used to receive the insulators to be recycled and transport the insulators to a disassembly workbench 4;

[0047] The disassembling unit comprises a disassembling machine 3 and a disassembling workbench 4. When there are insulators to be recycled on the disassembling workbench 4, the pneumatic hammer of the disassembling machine 3 is started to hammer the metal end of the insulator, and cooperates with the C-shaped support on the disassembling workbench 4 to break the porcelain shed and separate it from the metal core rod. The broken porcelain pieces are collected by the discharging unit 1 and transported to the recycling box 5, and the separated metal core rod falls into the discharging slide rail in the space below the C-shaped support for collection.

[0048] like Figure 2 and Figure 3 As shown, the loading unit 2 has a conveying plane 21 for driving the insulator to move, a fixed groove 22 is provided at a set position of the conveying plane 21, an opening 23 facing the disassembly workbench 4 is provided on one side of the fixed groove 22, and a transverse push plate 25 driven by a transverse cylinder 24 is provided on the other side, and the movement direction of the transverse push plate 25 is perpendicular to the transportation direction of the insulator 6.

[0049] In this embodiment, the conveying plane 21 has a strip groove for accommodating the metal head at one end of the insulator 6, so that the metal head at the other end of the insulator 6 is arranged vertically. The set position of the strip groove has a fixed groove 22, and the fixed groove 22 is used to accommodate the lower half of the insulator 6. When the insulator 6 is driven by the conveying plane 21 to move to a position where it can enter the disassembly workbench 4, the lower half sinks into the fixed groove 22, the transverse cylinder 24 is actuated, and the transverse push plate 25 is used to push the insulator 6 through the opening 23 into the disassembly workbench 4, ready for disassembly.

[0050] In this embodiment, the conveying plane 21 is driven by a motor, and the specific structure is not limited. A belt, a roller or any other component can be used to form a component capable of transporting insulators.

[0051] In this embodiment, the transverse push plate 25 is arc-shaped, and the curvature of the arc matches the diameter of the insulator 6 .

[0052] It should be noted that the "lateral movement" involved in the transverse movement cylinder 24 and the transverse movement push plate 25 refers to the "lateral movement" based on the moving direction of the insulator 6 on the conveying plane 21, that is, the movement direction of the transverse movement push plate 25 is perpendicular to the moving direction of the insulator 6.

[0053] In this embodiment, the porcelain insulator is manually transferred to the conveying plane 21, and its metal cap is sunk into the strip groove of the conveying plane 21. The porcelain insulator is driven by a motor to move to the set position of the conveying line, that is, to the position of the fixed groove 22, and the transverse cylinder 24 is actuated to push the porcelain insulator into the working area of ​​the dismantling machine 3. The loading unit 2 has a certain transportation distance, thereby isolating the manual operation area from the dismantling area to ensure personal safety.

[0054] like Figure 4 As shown, the disassembling unit includes a disassembling machine 3 and a disassembling workbench 4. A loading slide rail 32 is provided on the disassembling workbench 4. One end of the loading slide rail 32 is connected to the opening 23 on the conveying plane 21, and the other end is a disassembling position; thereby, the insulator 6 can be pushed from the fixed groove 22 into the loading slide rail 32 by means of the transverse cylinder 24, and reaches the disassembling position along the loading slide rail 32; the disassembling machine 3 has an air hammer 31, and the disassembling position is directly below the air hammer 31. A C-shaped support is provided at the disassembling position, and the opening of the C-shaped support faces the loading slide rail 32. A discharge slide rail 33 is provided directly below the hollow part of the C-shaped support.

[0055] The disassembly workbench 4 is a hollow structure, the hollow part of which is not smaller than the hollow part of the C-shaped support, and is used to allow the separated metal core rod to fall into the discharge slide rail 33 below.

[0056] When the insulator enters the C-shaped support along the loading slide 32, the lower bottom surface of the insulator's porcelain shed is abutted by the C-shaped support, and the metal head at the bottom is located in the hollow part of the C-shaped support. The air hammer 31 is started and hammers the metal end at the top of the insulator in the vertical direction. The impact force generated by the air hammer is transmitted to the porcelain shed by the metal end, and the porcelain shed is broken under the shearing action of the C-shaped support. The broken porcelain pieces are distributed on the outer surface of the disassembly workbench 4, and the separated metal core rod falls from the hollow part of the C-shaped support into the discharging slide 33, and is guided and collected by the discharging slide 33.

[0057] The C-type support is designed according to the largest outer diameter of the metal column head; an outer shield is provided on the outside of the workbench to prevent debris from splashing and dust from leaking during the hammering and crushing process, ensuring personal and environmental safety.

[0058] The discharging unit 1 is a belt conveyor, the starting end of which is located in the space below the disassembling unit, and is used to receive the broken ceramic pieces and transport them to the recycling box 5. The belt conveyor is a prior art. Since the starting end is located in the space below the disassembling unit, the belt conveyor selects a transportation direction from low to high, for example Figure 5 The structure shown.

[0059] The above device takes into account the structural characteristics of porcelain insulators, and uses a feeding unit to feed the porcelain insulators to be recycled one by one to the disassembly workbench and place them in a "C"-shaped support. The pneumatic hammer of the disassembly machine is used to hammer one end of the core rod of the insulator, so that the porcelain shed part of the insulator is sheared by the C-shaped support and broken, and the metal core rod falls into the discharge slide rail from the hollow part of the C-shaped support, so as to achieve the separation of the metal core rod and the porcelain shed fragments. The device can be operated in an automated manner without manual participation. During the process, the feeding unit is used to separate the operation that may cause fragment splashing from the manual feeding operation, thereby reducing the possible personal injury of porcelain pieces. In actual engineering, the area where broken porcelain pieces may splash is determined according to the specifications of the insulators to be recycled, thereby determining the stroke of the feeding unit. Only a small amount of manual handling operations are adopted in the feeding part and the final transfer part, and the disassembly process that is prone to injury is physically isolated from the manual operation part, thereby reducing the possible injury to personnel.

[0060] Embodiment 2:

[0061] like Figure 7 As shown, the working method of the porcelain insulator recovery device comprises the following steps:

[0062] (1) Loading of porcelain insulators: The porcelain insulators are manually transferred to the loading unit 2, and the porcelain insulators are moved to the disassembly area along with the loading unit 2;

[0063] (2) Automatic clamping: When the incoming insulator is detected, the traverse cylinder of the loading unit 2 moves the insulator along the loading slide rail 32 to the C-shaped support of the disassembly unit;

[0064] (3) Shed disassembly: The disassembly machine is started, and the hammer sleeve falls rapidly under the drive of the air hammer, hitting the metal column head part on the upper part of the insulator; the shed fragments fall onto the belt of the discharge unit below; the metal cap falls into the discharge slide rail below for recovery; the shed fragments are transported by the discharge unit to the recovery box 5 for subsequent sorting and storage;

[0065] (5) Temporary storage: The recycling box 5 first arrives at the automatic weighing station along the conveyor line, where it is scanned, weighed and photographed, and then arrives at the stacker docking station along the conveyor line. The stacker delivers the recycling box to the sorting area or storage according to the disassembly process requirements.

[0066] Based on the structural characteristics of porcelain insulators, the loading unit is used to feed the porcelain insulators to be recycled one by one to the disassembly workbench and place them in the "C"-shaped support. The pneumatic hammer of the disassembly machine is used to hammer one end of the core rod of the insulator, so that the porcelain shed part of the insulator is broken by the shearing action of the C-shaped support, and the metal core rod falls into the discharging slide rail from the hollow part of the C-shaped support, thereby realizing the separation of the metal core rod and the porcelain shed fragments. It can operate in an automated manner without manual participation, thereby reducing possible personal injury caused by porcelain pieces.

[0067] A loading unit with a certain transport distance is used to separate the manually operated loading area and the automatically operated disassembly area. When disassembly is required, the insulators are pushed into the disassembly position one by one using a cylinder to ensure that during the disassembly operation, the flying porcelain pieces do not affect the manual operation and reduce possible personal injury.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention to those skilled in the art. The present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
