Description
Technical field
This application involves a kind of specific purpose tools for replacing pin.
Background technology
M type pins are also referred to as W type pins, and material is mostly stainless steel, brass or iron matter, is chiefly used in various electric armour clamps.Two
It when a suspension insulator connection, is connect with bulb using ball-and-socket, needs to be inserted into M pins after connection, could lock.It is charging more
During changing single string strain insulator operation, if M pins cannot be accurately installed in place, once being subjected to displacement and deforming, insulate
After pulling plate unclamps, it is possible to the serious consequence for causing line conductor to fly out.And in the prior art, the insulation of charged for replacement list string strain insulator
The period of the day from 11 p.m. to 1 a.m, when ground potential electrician is sold using operating lever connection pin pulling clamp to restore the M of installation insulator chain and bowl head junction, because pulling out
Pin pliers grip is excessive, and M pin stress can be caused excessive and deformed, keep M pin installations not in place, or even can fall from bowl head opening
Under, leave security risk.
Invention content
The purpose of the application is to propose a kind of specific purpose tool of replacement pin simple in structure, easy to operation.
What the application was realized in：The specific purpose tool for replacing pin includes mobile jib, and carrying handle is provided in the middle part of mobile jib,
Mobile jib front end is provided with connecting rod, and connecting rod is fixedly arranged at the front end with operating head, and the operating head is U-shaped head, is arranged in operating head
There is the plugboard for selling grafting with M, salient point is provided on the two sides of plugboard, is offered on the side wall of the operating head open end
Screw hole is screwed with screw rod in screw hole.
Operating head open end two side is arc elastic part, forms packet header, and plugboard is to open end in operating head
Space forms outer small interior big space.
The plugboard cross section is wedge shape.
The connecting rod is clamping with mobile jib or is screwed on.
Due to implementing above-mentioned technical proposal, the application can be sold with M or split pin connection is secured, keeps M pins can be complete
It is inserted under whole state inside bowl head, and more convenient M pins or split pin can also be removed.The utility model improves replacement
The serviceability rate and accuracy of pin.
Description of the drawings
The concrete structure of the application is provided by drawings and examples below：
Fig. 1 is the structural schematic diagram of the application.
Legend：1. carrying handle, 2. mobile jibs, 3. connecting rods, 4. operating heads, 5. plugboards, 6. expansion heads, 7. screw rods.
Specific implementation mode
The application is not limited by following embodiments, can be determined according to the technical solution of the application and actual conditions specific
Embodiment.
As shown in Figure 1, the specific purpose tool for replacing pin includes mobile jib 2,2 middle part of mobile jib is provided with carrying handle 1, in mobile jib 2
Front end is provided with connecting rod 3, and connecting rod 3 is fixedly arranged at the front end with operating head 4, and the operating head 4 is U-shaped head, the setting in operating head 4
There is the plugboard 4 for selling grafting with M, salient point is provided on the two sides of plugboard 4, is opened on 4 open end side wall of the operating head
Equipped with screw hole, screw rod 7 is screwed in screw hole.
Further, 4 open end two side of the operating head is arc elastic part, forms packet header 6, grafting in operating head 4
The space of plate 4 to open end forms outer small interior big space, and the space is being clamped the round plunger of split pin.The packet header 6
It fits over and positions outside bowl head, M pins are accurately inserted in place by fast and easy.
Further, 4 cross section of the plugboard is wedge shape, to coordinate the grafting with M pins.
Further, the connecting rod 3 is clamping with mobile jib 2 or is screwed on.
In use, taking out screw rod 7, plugboard 4 is inserted into M pins, 4 two sides of plugboard are contacted with M pin inner walls, due to inserting
The protrusion of 4 two sides of fishplate bar increases the frictional force that inner wall is sold with M, so that plugboard 4 and M pins is firmly combined with, keeping M to sell can be
It is inserted under good working condition inside bowl head, improves the serviceability rate and accuracy of installation M pins when replacing single string strain insulator.It chooses
When M is sold, passes through M to sell round head screw rod 7, can firmly extract outward.
In use, taking out screw rod 7, split pin round head is caught in plugboard 4 to the space of open end, you can will be open
Pin is delivered in place.Choose split pin when, by screw rod 7 pass through split pin round head, outward firmly can extract split pin.
The above technical characteristic constitutes the most preferred embodiment of the application, is imitated with stronger adaptability and best implementation
Fruit can increase and decrease inessential technical characteristic according to actual needs, to meet the needs of different situations.
