Abstract
The utility model relates to a transmission line examines and repair instrument technical field. An insulator replacing tool, includes insulator spindle and couple, the couple is installed in insulator spindle one end, the insulator spindle is connected through the rotating head and is unciform link plate, the link plate is relative with the couple position. The utility model discloses it is nimble convenient to use, and the centre installs the rotating head additional, has compensatied the awkward shortcoming of the great use of wire rope toughness, and the kit demonstration adopts suitable length to satisfy the change of the insulator of different model length when using the double hook with the calabash operation.
Description
Technical field
The utility model relates to power transmission lines overhauling technical field of tools, be specially a straight line pole and change insulator aid.
Background technology
In the service work of transmission line, changing straight line pole insulator is one of key operation task, and the tool design size that current replacing straight line pole insulator uses is less than the length of bunch of insulator, and existing method uses steel wire rope head to extend.Steel wire rope head toughness is comparatively large, uses it to hang installing when work high above the ground and comparatively requires great effort, and can produce very large opposite force when steel wire rope kinking amplitude is larger, and steel wire rope oppositely can eject after slippage and accidentally injure operating personnel from hand, there is potential safety hazard.Steel wire rope head braiding simultaneously needs labor intensive comparatively large, and the steel wire rope head quality knit out is also uneven because of the skilled degree difference of braiding personnel, brings potential safety hazard to operation process.
The straight line pole that this project uses changes the Length Quantity body processing of insulator aid according to 110kV, 220kV insulator for extending the replacing such as double hook, cucurbit instrument, there is easy installation, the feature such as easy to operate, decrease the job step when work high above the ground, to save time and laborsaving, while improve operating efficiency, also ensured the safety of operation process.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned technical problem, provides a kind of insulator replacement tool, specifically provides a kind of simple to operate, lightweight, be convenient for carrying, safe and reliable, be convenient to the instrument that insulator changed by power transmission lines overhauling work cathetus shaft tower.
Technical solution of the present invention is: a kind of insulator replacement tool, comprises insulating bar and hook, and described hook is arranged on insulating bar one end; Described insulating bar connects in hook-shaped link plate by swivel head, and described link plate is relative with hook position.
Here link plate can be hooked on the tower material of cross arm of tower head opening upwards, and link up with the upper hook being used for connecting double hook and cucurbit, wherein swivel head can rotate arbitrarily, meets its operation at any angle.
Preferably, described link plate is made up of lath bending, and link plate is provided with the hold-down screw screwed inside it.When link plate is hooked on the tower material of cross arm of tower head opening upwards, screw can be used to fix link plate at tower material interior angle further.
Preferably, described swivel head end is provided with installation notch, described notch and the installation end Corresponding matching being arranged on insulating bar, link plate, and is bolted.Here bolt can use latch to replace, be same as quick-detachment, change link plate, rotate first-class.
Preferably, described swivel head comprises link and rotating shaft, and described link is arranged on rotating shaft two ends, and link is provided with notch and vertically runs through notch through hole.The structure of swivel head linkage section is disclosed here, can other devices of Fast Installation.
Preferably, described hooking slits is provided with spring latch device.Spring latch device can prevent hook in use procedure from deviating from.
Preferably, described hook is arranged in insulating bar end notch, and is bolted.Such hook can Fast Installation, replacing.
Preferably, described insulating bar comprises the extension rod of some insulation, is threaded connection installation between extension rod.Here the number of extension rod can be proved according to actual linear insulator string length and determine, meets the use of polymorphic type and 110kV, 220kV insulator string.
The utility model beneficial effect is:
1. the utility model is flexible and convenient to use, and centre installs swivel head additional, and compensate for the larger shortcoming using clumsiness of steel wire rope toughness, kit demonstration adopts suitable length, with the replacing of the insulator of different model length when satisfied use double hook and cucurbit operation.
2. the utility model sound construction, wear-resistant and corrosion, material and cost of labor low, do not exist because maintaining bad cause restricting body corrosion and the safety problem that causes, especially use under being suitable for field extreme environment, can the personal safety of safeguard work personnel, effectively avoid the bounce-back caused because of steel wire rope to hit body part and hurt by burr, improving the operating efficiency that linear insulator changes operation.
3. the utility model simple structure, is convenient to operating personnel's adjustment on bar and installs and uses.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-insulating bar, 2-swivel head, 3-link plate, 4-hold-down screw, 5-hook, 6-bolt.
Embodiment
Below in conjunction with accompanying drawing, the invention process is described.
As shown in Figure 1, a kind of insulator replacement tool, comprises insulating bar 1, swivel head 2, hook 5 and link plate 3.Hook 5 is arranged in insulating bar 1 end notch, and is connected by bolt 6.Insulating bar 1 connects in hook-shaped link plate 3 by swivel head 2, and link plate 3 is relative with hook 5 positions; Link plate 3 is made up of lath bending, and link plate 3 is provided with the hold-down screw 4 screwed inside it.Swivel head 2 end is provided with installation notch, described notch and the installation end Corresponding matching being arranged on insulating bar 1, link plate 3, and is connected by bolt 6.Further, described swivel head 2 comprises link and rotating shaft, and described link is arranged on rotating shaft two ends, and link is provided with notch and vertically runs through notch through hole.The structure of swivel head 2 linkage section is disclosed here, can other devices of Fast Installation.
Further, described hook 5 opening is provided with spring latch device.Spring latch device can prevent linking up with 5 in use procedure and deviate from.
Further, preferably, described insulating bar 1 comprises the extension rod of some insulation, is threaded connection installation between extension rod.Here the number of extension rod can be proved according to actual linear insulator string length and determine, meets the use of polymorphic type and 110kV, 220kV insulator string.
The utility model structural design adopts lighter material to make when stressed license, facilitate one man operation.
The concrete operations content that straight line pole changes insulator aid is as follows:
