Description

Technical Field

[0001] This utility model relates to the field of component transfer and storage of electrical insulation devices, and specifically to a batch transfer device for composite insulators. Background Technology

[0002] Composite insulators, as core components of power transmission lines, substations, and electrified railways, are gradually replacing traditional ceramic insulators due to their lightweight, pollution flashover resistance, and aging resistance. With the expansion of ultra-high voltage power grids and the integration of new energy sources, the annual demand for composite insulators has exceeded several million units, but significant challenges remain in their production, storage, and transportation.

[0003] During the processing, storage, and transportation of composite insulators, batch transfer of finished and semi-finished composite insulators is typically required. Due to the unique structure of composite insulators, the glass fiber reinforced epoxy resin winding tubes and silicone rubber sheds are prone to micro-cracks or tears when subjected to mechanical impact or uneven compression, thus affecting their electrical performance. Currently, widely used transfer methods and tools in the industry generally face challenges of low loading and unloading efficiency and insufficient space utilization due to a lack of flexibility. These problems highlight their limitations.

[0004] The simple pallet stacking method limits the amount of goods transported at one time, and the loading and unloading process is time-consuming.

[0005] Fixed racks lack shock absorption design, and their rigid structure, coupled with the lack of shock absorption design for composite insulators, cannot effectively absorb vibrations during transportation, which may lead to an increased breakage rate. Some racks use straps for auxiliary fixation, but the loading and unloading process requires repeated disassembly and reassembly of the straps, which is not only cumbersome, but the friction of the straps on the surface of the insulators may also cause damage.

[0006] While customized turnover boxes can protect products of specific specifications, they have poor versatility and high production costs, which can easily lead to increased warehousing costs.

[0007] For the reasons mentioned above, the shortcomings of these traditional solutions in terms of protection, automation, and economy can no longer meet the needs of large-scale production. The high breakage rate and inefficient loading and unloading under current technological conditions have constrained the reliability and economy of the power equipment supply chain. Utility Model Content

[0008] The technical problem solved by this utility model is to provide a batch transfer device for composite insulators, which can be used to solve the defects in the above-mentioned technical background.

[0009] The technical problem solved by this utility model is achieved by the following technical solution:

[0010] A batch transfer device for composite insulators includes a transfer vehicle with a base plate as a support surface. The base plate is square or rectangular and its surface is a placement area for composite insulators. The composite insulators to be transferred are placed upright in the placement area.

[0011] The base plate has uprights formed at its four corners, and two sets of parallel vertical rods are mounted on the uprights. Each set of vertical rods includes two primary guide slides and a horizontal connecting rod. The two primary guide slides are respectively mounted on two uprights on the same side of the base plate and can slide synchronously up and down along the uprights. The vertical rods have multiple transverse rods mounted on the horizontal connecting rods. The transverse rods include two secondary guide slides and a longitudinal connecting rod. The two secondary guide slides are respectively mounted on different horizontal connecting rods and can slide synchronously horizontally along the horizontal connecting rods. The longitudinal connecting rod connects the two secondary guide slides, is perpendicular to the transverse connecting rods, and has a locking component for securing the upper end of the composite insulator.

[0012] As a further limitation, the transfer vehicle is equipped with casters with brakes on the underside of the base plate as a moving device to facilitate the movement of the transfer vehicle.

[0013] As a further limitation, the transfer vehicle is equipped with a towing structure or push-pull handle on one side of the vehicle body, which facilitates connection with traction equipment or manual dragging or pushing of the transfer vehicle.

[0014] As a further limitation, the base plate is a detachable assembly structure on the transfer vehicle, and several limiting and receiving grooves are formed in an array on the surface of the base plate, the limiting and receiving grooves matching the bottom shape of the composite insulator to be transferred.

[0015] The base plate is a modular splicing structure, with one or more limiting and receiving slots formed on each splicing unit. The splicing units are spliced ​​and fixed in position through toothed interfaces.

[0016] The limiting and receiving groove is equipped with a shock-absorbing pad.

[0017] As a further limitation, the upright is a round steel pipe, and the top surface of the round steel pipe is sealed with a limiting cap; both the horizontal connecting rod and the vertical connecting rod are square steel pipes, and the horizontal connecting rod is provided with anti-slip sleeves at both ends.

[0018] As a further limitation, both the primary guide slide and the secondary guide slide are provided with independent position locking devices. The position locking devices are mechanical locking structures, preferably one or a combination of buckles, snap buckles, spring pins, threaded pins, and clamps, to ensure that the slide can be securely locked in any position.

[0019] As a further limitation, the secondary guide slide has a detachable assembly structure on the cross link.

[0020] As a further limitation, the locking assembly is a detachable assembly structure on the longitudinal connecting rod.

[0021] As a further definition, the locking assembly includes a cross-shaped base, on which an elastic protective sleeve matching the shape of the cross-shaped base is wrapped. The elastic protective sleeve has a smooth arc transition at the right angle position corresponding to the cross-shaped base, and an air-expanding pad is lined on the inner side of the arc surface. The locking assembly uses the air-expanding pad as the locking contact surface at the upper end of the composite insulator.

[0022] Beneficial effects: This utility model of a batch transfer device for composite insulators features a compact structure, simple operation, wide applicability, and excellent protective performance. Through the setting of vertical and horizontal rods, the placement space of composite insulators can be flexibly adjusted to meet the batch transfer needs of insulators of different specifications.

Attached Figure Description

[0023] Figure 1 This is a schematic diagram of a preferred embodiment of the present invention.

[0024] The components include: 1. Limit cap; 2. Upright pole; 3. Fastening assembly; 4. Winding tube; 5. Silicone umbrella skirt; 6. Longitudinal connecting rod; 7. Primary guide slide; 8. Position locking device; 9. Transfer cart; 10. Universal wheel; 11. Splicing unit. Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0026] See Figure 1 A preferred embodiment of a batch transfer device for composite insulators is provided. In this embodiment, the main body of the device is a transfer vehicle 9, which is a flatbed trolley and includes a carrying platform. The carrying platform is a square platform with casters 10 at the bottom for travel, so as to facilitate flexible movement of the position.

[0027] In different embodiments, the transfer vehicle 9 may also be equipped with a towing structure or a push-pull handle to facilitate connection with traction equipment or manual dragging or pushing of the transfer vehicle.

[0028] The surface of the transport vehicle 9's carrying platform is formed with a square blind groove, and a base plate is set in the square blind groove. The surface of the base plate is the placement area for the composite insulator. In this embodiment, nine splicing units 11 are arranged in an array in the square blind groove. The splicing units 11 are arranged in a 3×3 matrix in the square blind groove and together form the base plate that carries the composite insulator.

[0029] Positioning bosses are provided on the edges of adjacent splicing units 11 in the base plate and on the four sides of the square blind slot. Adjacent splicing units 11 and the outermost splicing units 11 are tightly fitted with the wall of the square blind slot through toothed interfaces on the positioning bosses, ensuring the splicing units 11 remain stable and do not shift within the square blind slot. A limiting groove is formed in the middle of the surface of each splicing unit 11. The shape of this limiting groove matches the bottom of the composite insulator to be transported, supporting the composite insulator winding tube 4 and ensuring its stable vertical placement, preventing bottom swaying or displacement of the composite insulator during transportation. The structural design of the splicing units 11 in the base plate allows for flexible adjustment of the groove size according to different specifications of insulators, further improving the versatility and practicality of the device, and ensuring the efficiency and safety of batch transport of composite insulators, especially medium and large-sized composite insulators.

[0030] In another embodiment, the bottom shell of the limiting and receiving slot is equipped with a shock-absorbing pad. The shock-absorbing pad is made of a highly elastic material and has good buffering and shock absorption performance. It can effectively absorb vibration and impact during transportation and further protect the composite insulator from damage.

[0031] At each of the four corners of the transfer vehicle 9, there is a vertical pole 2. The vertical pole 2 is a round steel pipe structure, and the top is limited and sealed by a limiting cap 1. Two sets of parallel vertical frames are mounted on the vertical pole 2. Each set of vertical frames includes two primary guide slides 7 and a horizontal connecting rod (not shown, but in the same plane as the horizontal frame) connecting the two primary guide slides 7. The primary guide slides 7 can slide up and down along the vertical pole 2, thereby adjusting the height of the vertical frame to accommodate the height requirements of composite insulators of different lengths after erection. A position locking device 8 is provided on the primary guide slide 7. This position locking device 8 can be a snap-fit, snap-fit, spring pin, threaded pin, or clamp in different embodiments, used to ensure that the primary guide slide 7 can be securely locked after being adjusted to the appropriate height, preventing slippage during transfer.

[0032] The vertical poles are equipped with multiple horizontal poles on the horizontal connecting rods. The number of these poles is related to the arrangement of the composite insulators on the base plate. This ensures that the composite insulator winding tube 4 placed on the splicing unit 11 is clamped in four directions (front, back, left, and right) by the clamping assembly 3, thereby fixing the upper end position of the composite insulator.

[0033] The cross link is a square steel tube structure with anti-slip sleeves at both ends to ensure the stable sliding of the secondary guide slide on the cross link. The secondary guide slide is also equipped with a position locking device similar in function to the position locking device 8 on the primary guide slide 7 to ensure the stable positioning of the secondary guide slide on the cross link and prevent sliding.

[0034] The device also includes multiple sets of transverse frames on the transverse connecting rod. Each set of transverse frames includes two secondary guide slides (not shown, fitted onto the transverse connecting rod and capable of moving along the transverse connecting rod) and a longitudinal connecting rod 6 connecting the two secondary guide slides. The secondary guide slides can slide horizontally along the transverse connecting rod, thereby adjusting the position of the transverse frames to accommodate the stacking requirements of composite insulators of different sizes.

[0035] A locking assembly 3 is installed on the longitudinal connecting rod 6. The locking assembly 3 is used to lock the upper end of the composite insulator, ensuring the stability of the insulator during transportation. The locking assembly 3 includes a cross-shaped base, which is in the same plane as the transverse rod. An elastic protective sleeve is wrapped around the cross-shaped base. The elastic protective sleeve consists of upper and lower half-shells, which are connected and disassembled by countersunk hexagonal sockets. The elastic protective sleeve has a smooth arc transition at the right angle position corresponding to the cross-shaped base, and an air-expanding pad is installed on the inner side of the arc surface. The locking assembly 3 uses this air-expanding pad as the locking contact surface for the exposed part of the upper winding tube 4 of the composite insulator, which has good cushioning and anti-slip performance, and can effectively prevent the insulator from slipping or being damaged due to vibration or collision during transportation.

[0036] In this embodiment, the transverse poles can be detachably assembled and disassembled on the transverse connecting rod via a secondary guide slide. The corresponding detachable assembly structure can be a bolted connection, a snap-fit ​​connection, or a slot connection, allowing for flexible adjustment of the number and position of the transverse poles according to actual needs. Simultaneously, the locking assembly can also be detachably assembled and disassembled on the longitudinal connecting rod 6 via two half-shells. This design provides the transfer device with greater flexibility and maintainability. When the transfer device needs to be adjusted to accommodate composite insulators of different specifications, operators can easily disassemble or reassemble the transverse poles and locking assemblies without replacing the entire transfer device, thus saving time and costs.

[0037] In this embodiment, the batch transfer device first moves the primary guide slide 1 to the limiting position of the limit cap 1 of the upright 1, and then completes the selection and assembly of the splicing unit 11 in the square blind groove on the surface of the bearing platform. The selection of the splicing unit 11 is based on the principle that when the composite insulator is upright on the limiting receiving groove of the splicing unit 11, the silicone sheds 5 between adjacent composite insulators do not come into contact.

[0038] Then adjust the position of the transverse poles so that they are positioned between adjacent composite insulators. At the same time, adjust the position and number of the fastening components on the transverse poles to match the composite insulators.

[0039] The vertical pole is then lowered using the primary guide slide 7, positioning the locking assembly 3 at the exposed portion of the winding tube 4 at the upper end of the composite insulator. Inflation of the air pad causes it to expand, tightly adhering to the surface of the winding tube 4 at the upper end of the composite insulator, achieving a stable locking effect. During transport, even encountering bumps or vibrations, the locking assembly 3 effectively prevents the composite insulator from shifting or colliding, providing cushioning and impact protection to ensure the safety and stability of the transport.

[0040] Under the technical conditions of this embodiment, by adjusting the positions of the horizontal and vertical poles, the batch transfer device can adapt to composite insulators of different specifications and quantities, provided that the base plate meets the placement requirements. This improves the flexibility and efficiency of the transfer, and has significant technical advantages and practical value.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical content of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
