Abstract
The invention discloses an insulating brake pull rod, and relates to the field of electric machinery. When the high-voltage disconnecting switch is used, an electrician can hold the telescopic pipe by hand, extend the telescopic pipe to a proper length, pull the pull ring to drive the insulating rope to separate the pressing plate from the switching frame, then sleeve the switching frame and the pressing plate on the high-voltage disconnecting switch, drop the fuse and the like, release the pull ring, and tightly clamp the high-voltage disconnecting switch, the drop fuse and the like by using the spring, so that the switching can be operated, the operation control capability is strong, and the insulating protection performance is good.
Description
Technical Field
The invention relates to the field of electric machinery, in particular to an insulating brake pull rod.
Background
The insulating brake pull rod is an insulating tool used for operating live equipment in a short time, such as a high-voltage isolating switch, a drop fuse and the like, and has an insulating protection function. The existing insulating brake pull rod is simple in design, cannot only clamp a high-voltage isolating switch, drop a fuse and the like, and causes the user to frequently slip off during operation, so that the control capability is poor.
Disclosure of Invention
The invention mainly solves the technical problem of providing an insulating brake pull rod which can tightly clamp and operate a high-voltage isolating switch, a drop fuse and the like and has strong insulating protection capability.
In order to achieve the above purpose, the present invention provides the following technical solutions: an insulating brake pull rod is characterized in that: the insulating brake pull rod comprises a telescopic pipe capable of freely stretching, a rectangular frame-shaped brake pull frame is arranged at one end of the telescopic pipe, a pressing plate is connected into the brake pull frame through two springs, the pressing plate is tightly attached to the inner wall of the brake pull frame by the aid of extension force of the springs, an insulating rope is connected to one end, close to the telescopic pipe, of the pressing plate, and the insulating rope penetrates through the brake pull frame and the telescopic pipe to be connected with a pull ring.
As a further optimization of the present solution, said telescopic tube is made of an insulating material.
As a further optimization of the technical scheme, the brake pull frame, the pressing plate and the springs are all made of stainless steel, and the springs are fixedly connected with the brake pull frame and the pressing plate through welding.
As a further optimization of the technical solution, the insulating rope is made of nylon material, and the pull ring is made of plastic.
The beneficial effect of adopting above technical scheme is: the telescopic pipe one end of this insulating brake pull rod is equipped with the brake pull frame, has the clamp plate through two spring coupling in the brake pull frame, and the clamp plate is connected with insulating rope, and insulating rope passes the brake pull frame and telescopic pipe is connected with the pull ring. When the high-voltage disconnecting switch is used, an electrician can hold the telescopic pipe by hand, extend the telescopic pipe to a proper length, pull the pull ring to drive the insulating rope to separate the pressing plate from the switching frame, then sleeve the switching frame and the pressing plate on the high-voltage disconnecting switch, drop the fuse and the like, release the pull ring, and tightly clamp the high-voltage disconnecting switch, the drop fuse and the like by using the spring, so that the switching can be operated, the operation control capability is strong, and the insulating protection performance is good.
Drawings
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of an insulated brake pull rod according to the present invention.
Wherein, 1-extension pipe, 2-brake frame, 3-clamp plate, 4-spring, 5-insulating rope, 6-pull ring.
Detailed Description
A preferred embodiment of an insulated brake pull rod according to the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 shows an embodiment of an insulated brake pull rod according to the present invention: this insulating brake pull rod is including the flexible pipe 1 that can freely stretch out and draw back, and flexible 1 one end of pipe is equipped with the switching-off frame 2 of rectangle frame form, is connected with clamp plate 3 through two springs 4 in the switching-off frame 2, and the extension power of spring 4 forces clamp plate 3 and 2 inner walls of switching-off frame to hug closely together tightly, and clamp plate 3 is close to flexible 1 one end of pipe and is connected with insulating rope 5, and insulating rope 5 passes switching-off frame 2 and flexible pipe 1 and is connected with pull ring 6.
As shown in fig. 1, the telescopic pipe 1 is made of an insulating material, has a good insulating effect, and the telescopic pipe 1 can be freely stretched and contracted, so that the telescopic pipe is suitable for operating electric facilities with different heights. The brake pull frame 2, the pressing plate 3 and the spring 4 are made of stainless steel, hardness is high, corrosion resistance is good, and the spring 4 is fixedly connected with the brake pull frame 2 and the pressing plate 3 through welding. The insulating rope 5 is made of nylon materials, and the pull ring 6 is made of plastics, so that the insulating effect is good, and the safety performance is good.
When the telescopic tube is used, an electrician can hold the telescopic tube 1 by hand, extend the telescopic tube 1 to a proper length, pull the pull ring 6 to drive the insulating rope 5 to separate the pressing plate 3 from the switching-off frame 2, then sleeve the switching-off frame 2 and the pressing plate 3 on the high-voltage isolating switch, the drop fuse and the like, release the pull ring 6, and tightly clamp the high-voltage isolating switch, the drop fuse and the like by the switching-off frame 2 and the pressing plate 3 by using the spring 4, so that the switch can be operated, the operation control capability is strong, and the insulation protection performance is good.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept of the present invention, which falls into the protection scope of the present invention.
