Abstract
The R-shaped insulator pin extractor for the power transmission line comprises an insulating rod (1) and a toothed pin extracting hook (2) arranged at the head of the insulating rod, a pin installing hammer (3) is connected to the bent part of the hook, a screw hole is formed in the middle of a hammer body of the pin installing hammer (3), an adjusting bolt (4) is screwed into the screw hole to form a force-assisted fulcrum (5), and the axis of the adjusting bolt (4) is coaxial with the axis of the insulating rod (1); the front end of the pin installing hammer is connected with a pin taking hook (2) with teeth; a telescopic sleeve rod (6) is sleeved on the lower section of the insulating rod. The beneficial effects of the utility model are that, get the round pin in-process at transmission line R type insulator, have stable in structure, convenient operation, high-efficient laborsaving advantage.
Description
Technical Field
The utility model belongs to a round pin ware structure technique is got to transmission line R type insulator.
Background
The existing pin taking tool for the R-shaped insulator of the transmission line aims to hook out the R pin of the R-shaped insulator or push the R pin in an impact manner, and is a pure metal type. However, the existing tool is a simple hook made of metal or a telescopic pin extractor, the model of the simple hook for taking out the R pin is a large-tonnage insulator, such as a U300-U420 model, which is limited by the radian of the hook, and the R pin is installed by knocking and recovering. The telescopic pin extractor utilizes tensile impact force to hook out the R pin and recovers installation through impact force after contraction, and the telescopic pin extractor is difficult to extract and recover when used for large-tonnage insulators due to the utilization of the impact force.
Disclosure of Invention
The utility model discloses an it is just in order to overcome not enough that above-mentioned prior art exists and provide a stable in structure, convenient operation, high-efficient laborsaving transmission line R type insulator and get round pin ware.
The purpose of the utility model is realized through the following technical scheme:
The R-shaped insulator pin extractor for the power transmission line comprises an insulating rod and a toothed pin extracting hook arranged at the head of the insulating rod, a pin installing hammer is connected to the bent part of the hook, a screw hole is formed in the middle of a pin installing hammer body, an adjusting bolt is screwed into the screw hole to form a force assisting fulcrum, and the axis of the adjusting bolt is coaxial with the axis of the insulating rod; the front end of the pin installing hammer is connected with a pin taking hook with teeth; a telescopic sleeve rod is sleeved on the lower section of the insulating rod.
The beneficial effects of the utility model are that, get the round pin in-process at transmission line R type insulator, have stable in structure, convenient operation, high-efficient laborsaving advantage.
Drawings
Fig. 1 is a schematic structural diagram of a pin extractor for an R-type insulator of a power transmission line.
Detailed Description
as shown in fig. 1, the R-type insulator pin extractor for the power transmission line comprises an insulating rod 1 and a toothed pin-extracting hook 2 arranged at the head of the insulating rod, a pin-mounting hammer 3 is connected at the bent part of the hook, a screw hole is arranged in the middle of the hammer body of the pin-mounting hammer 3, an adjusting bolt 4 is screwed into the screw hole to form a force-assisted fulcrum 5, and the axial lead of the adjusting bolt 4 is coaxial with the axial lead of the insulating rod 1; the front end of the pin installing hammer is connected with a pin taking hook 2 with teeth; a telescopic sleeve rod 6 is sleeved on the lower section of the insulating rod.
Each part structure and effect:
The bolt can be adjusted: the length of the force-assisted fulcrum is lengthened and shortened by utilizing the rotation of the threads, so that the insulator is suitable for R-pin insulators with different sizes.
a pin-taking force-borrowing fulcrum: get the round pin and borrow the power to prop and form a fulcrum at R round pin insulator bowl head, get the round pin and borrow the power fulcrum and adopt the four sides star, make borrow power fulcrum and R round pin insulator bowl head better the harmony prevent to skid.
Installing a pin hammer: and the R pin knocks the pin when not completely entering, so that the installation can be quickly recovered.
Taking pin hooks with teeth: the pin hook with teeth penetrates through the top of the R-shaped pin and is connected with the pin to form a force application point, and the pin hook are prevented from sliding by adopting the surface with teeth.
Insulating telescopic handle: the insulating telescopic handle is a force point for the telescopic pin extractor, the R pin is hooked by the toothed pin-taking hook by means of the force point of the pin-taking hook to form a lever principle, and the length of the insulating telescopic handle can be adjusted to quickly take out the pin in a labor-saving manner.
