Abstract
The utility model discloses a kind of special mould clamp for live-line replacing strain insulator string, including front machete card, rear machete card, screw mandrel and insulation pulling plate, one end of insulation pulling plate is by machete card before screw mandrel connection, machete card after other end connection；The insulation pulling plate is that the veneer being made up of 3 epoxy phenol aldehyde glass materials is constituted, and is provided with two exhausting holes on veneer, fixes to form telescopic insulation pulling plate by the bolt through through hole between veneer.Pulley assembly is connected with the rear machete card, and pulley assembly is made up of pulley and A-frame.The insulation pulling plate that this utility model is made by epoxy phenol aldehyde glass, and two exhausting holes are provided with insulation pulling plate, the mechanical strength of insulation pulling plate is increased, while meeting the insulating requirements of livewire work；Connect pulley assembly again on rear machete card, the difficulty for changing strain insulator-string reduces, and this utility model also has easy to use, flexible operation, improves the operational security with changing strain insulator-string.
Description
Technical field
This utility model is related to the instrument used in a kind of transmission line of electricity high-voltage hot-line work, and specifically one kind is used for
The special mould clamp of live-line replacing strain insulator string.
Background technology
Grid equipment is constantly reformed in recent years, in order to suppress corona discharge, reduces line reactance, is increased multi-line power transmission and is held
Amount, current 220kv overhead transmission lines are generally set up using 630 arrangements of conductors of vertical double divisions.Where and line the wire of such circuit
Footpath is larger, and changing strain insulator string is one of modal livewire work of transmission line of electricity, but the insulation pulling plate of existing fixture
On there is potential safety hazard, be mainly reflected in tensile strength, it is impossible to ensure the safety of operating personnel.
Content of the invention
This utility model purpose is to provide a kind of tensile strength big live-line replacing strain insulator string personality card
Tool.
The purpose of this utility model is achieved through the following technical solutions：
For the special mould clamp of live-line replacing strain insulator string, including front machete card, rear machete card, screw mandrel and absolutely
Edge arm-tie, one end of insulation pulling plate is by machete card before screw mandrel connection, machete card after other end connection；The insulation pulling plate be by
The veneer composition that 3 epoxy phenol aldehyde glass materials are made, is provided with two exhausting holes, by the spiral shell through through hole between veneer on veneer
Bolt is fixed to form telescopic insulation pulling plate.
Pulley assembly is connected with the rear machete card, and pulley assembly is made up of pulley and A-frame.
The pitch stroke of the screw mandrel is 4mm.
The telescopic scope of the insulation pulling plate is 2000mm～2900mm.
The insulation pulling plate that this utility model is made by epoxy phenol aldehyde glass, and two exhausting holes are provided with insulation pulling plate,
The mechanical strength of insulation pulling plate is increased, while meeting the insulating requirements of livewire work；Connect assembly pulley again on rear machete card
Part, the difficulty for changing strain insulator-string reduce, and this utility model also has easy to use, flexible operation, improves with changing strain insulator-string
Operational security.
Description of the drawings
Below in conjunction with the specific embodiment of accompanying drawing illustrated embodiment, the above of the present utility model is remake further
Detailed description.
Fig. 1 is structural representation of the present utility model.
The schematic diagram of Fig. 2 this utility model pulley assemblies.
Labelling in figure：Machete card before 1-, 2- screw mandrels, 3- insulation pulling plates, 31- veneers, 311- through holes, 312- bolts, after 4-
Machete card, 5- pulley assemblies, 51- pulleys, 52- A-frames.
Specific embodiment
This utility model provides a kind of special mould clamp of the big live-line replacing strain insulator string of tensile strength, such as schemes
Shown in 1, it includes that front machete card 1, screw mandrel 2, insulation pulling plate 3 and rear machete card 4, the front machete card 1 are connected absolutely by screw mandrel 2
Edge arm-tie 3, machete card 4 after the connection of insulation pulling plate 3.
The insulation pulling plate 3 is that the veneer 31 being made up of three epoxy phenol aldehyde glass materials is constituted, and is provided with two on veneer 31
Exhausting hole 311, is fixedly connected the scalable insulation pulling plate 3 of composition by the bolt 312 through through hole 311 between veneer 31, can stretch
The scope of contracting is 2000mm～2900mm, to meet the replacing needs of different strain insulator-strings.
Pulley assembly 5 is connected with the rear machete card 4, and pulley assembly 5 is made up of pulley 51 and A-frame 52, three
Pulley 51 is raised by angle support 52, is reduced the task difficulty of replacing strain insulator-string, more be ensure that the safety of staff.
It should be noted that the pitch stroke of the screw mandrel 2 is 4mm, pitch is little, helical pitch is little, effectively reduces the coefficient of waste,
High precision and laborsaving.
The lifted embodiment of this utility model or embodiment are entered to the object, technical solutions and advantages of the present invention
One step is described in detail, and be should be understood that embodiment provided above or embodiment are only the preferred embodiment of the present invention
, not in order to limit the present invention, all any modifications made for the present invention within the spirit and principles in the present invention, equivalent
Replace, improve etc., should be included within the scope of the present invention.
