Abstract
The utility model relates to a tool for taking down a spring pin at a joint on an insulator, in particular to a device for replacing the spring pin on the insulator in a hot-line way, which comprises a caliper body formed by articulating two handles (1), and a lengthened insulating rod (5), wherein one end of each handle (1) is a caliper mouth. The device is characterized in that the other end of each handle (1) is respectively connected with a nut (4) fixedly; the axial lines of the two nuts (4) are coincident; a screw (2) passes through the two nuts (4) and is in thread fit with the two nuts; and the lengthened insulating rod (5) is connected with the screw (2). In the utility model, by rotating the screw, the opening and the closing of the caliper mouth can be smoothly achieved, and the clamping strength of the caliper mouth can be controlled conveniently, so that the spring pin on the insulator can be taken down easily in the hot-line way.
Description
Technical field
The utility model relates to the instrument that takes off the spring catch of junction on the insulator, especially the device of charged for replacement insulator upper spring pin.
Background technology
At present generally use action bars to cooperate the spring catch of taking-up insulator junction with splitting during live line working on the transmission line of each department, what use for many years all is standard component, but according to actual operating position, line design insulator kind is a lot, the used material of spring catch also has multiple (as copper, iron, steel) etc., there is write off difficulty in various degree during operation, the especially common tight inadequately problem of splitting clamp springs pin.
The utility model content
The purpose of this utility model provides a kind of device of charged for replacement insulator upper spring pin, and it is operated easily, and strength is very big when the clamp springs pin, makes things convenient for the staff to take off spring catch.
A kind of device of charged for replacement insulator upper spring pin, comprise by two hinged calipers that form of handle, wherein an end of two handles is a jaw, its special feature is, the other end of described two handles is fixedly connected with nut separately, the dead in line of these two nuts, other have a screw rod pass these two nuts and with its threaded engagement, and one the lengthening insulating bar so that be connected with screw rod.
Wherein extend between insulating bar and the screw rod to removably connecting.
Wherein the end away from the lengthening insulating bar is equipped with stop nut on screw rod.
The utility model can realize the switching of jaw smoothly, and can control the clamping dynamics of jaw easily by rotary screw, thereby is easy to just can chargedly take off the spring catch on the insulator.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises by two handles, the 1 hinged caliper that forms, wherein an end of two handles 1 is a jaw, the other end of two handles 1 is fixedly connected with nut 4 separately, the dead in line of these two nuts 4, other have a screw rod 2 pass these two nuts 4 and with its threaded engagement, and one the lengthening insulating bar 5 so that be connected with screw rod 2, usually between lengthening insulating bar 5 and the screw rod 2 for removably connecting, for example be threaded or connect by pin.
Excessively break away from screw rod 2 for fear of handle 1 rotation, therefore the end away from lengthening insulating bar 5 is equipped with stop nut 3 on screw rod 2.
Claims (3)
1. the device of a charged for replacement insulator upper spring pin, comprise by the hinged caliper that forms of two handles (1), wherein an end of two handles (1) is a jaw, it is characterized in that: the other end of described two handles (1) is fixedly connected with nut (4) separately, the dead in line of these two nuts (4), other have a screw rod (2) pass these two nuts (4) and with its threaded engagement, and one the lengthening insulating bar (5) so that be connected with screw rod (2).
2. the device of charged for replacement insulator upper spring pin as claimed in claim 1 is characterized in that: between insulating bar that wherein extends (5) and the screw rod (2) for removably connecting.
3. the device of charged for replacement insulator upper spring pin as claimed in claim 1 or 2 is characterized in that: wherein an end of going up away from lengthening insulating bar (5) at screw rod (2) is equipped with stop nut (3).
