Description

A kind of multifunctional pin pulling pliers for insulator R-type pin

technical field

The utility model belongs to the auxiliary field of power transmission lines, in particular to a multifunctional pin puller for R-shaped pins of insulators.

Background technique

Insulators are used to support and fix busbars and live conductors, and to provide sufficient distance and insulation between live conductors or between conductors and the earth. Insulators should have sufficient electrical insulation strength and moisture resistance. It is a special insulation control.

At present, there are two kinds of pins commonly used in connecting bowl heads of insulators for 110kV-220kV transmission lines, one is M-type pins, with a utilization rate of 60%, and the other is R-type pins, with a utilization rate of 40%. At present, it only takes about 10 seconds to pull out the M-type pin with the commonly used pin pulling pliers, but it takes 6.5 minutes to pull out the R-type pin, and even some R pins cannot be pulled out. Therefore, in order to improve the replacement speed of the R-type pin insulator, it is necessary to design a pin puller for the R-type pin in the insulator.

Utility model content

The purpose of this utility model is to solve the technical problems mentioned above, and provide a multi-functional pin puller that can quickly pull out the R-shaped pin in the insulator and can also be quickly installed.

In order to achieve the above object, the technical solution adopted in the utility model is:

A multi-functional pin puller for insulator R-type pins, characterized in that it includes a pin puller, a pin hammer, a connecting rod and an operating handle, wherein the lower end of the pin puller is a hook portion and is in the shape of a pointed cone. The upper part is bent inward to form a bent part, and is connected with the lower part of the bolt hammer. The hammer surface of the bolt hammer is flat; the connecting rod is connected with the operating handle, and the other end of the connecting rod is connected The operating handle is flat, and the operating handle is inclined upwards, that is, the angle between the connecting rod and the connecting rod is an obtuse angle.

The pin-drawing hook, the pin hammer, the connecting rod and the operating handle are all integrally formed of stainless steel.

The bending angle of the bent end of the pin pulling hook is 90°, so as to form a fulcrum when pulling the pin.

The connection angle between the operating handle and the connecting rod is 150°.

The upper end of the operating handle is provided with a through hole, so as to facilitate the carrying and hanging of the pin pulling pliers.

The utility model multifunctional pin pulling pliers is easy to operate, safe and reliable. It can quickly pull out the R-shaped pin, and can also quickly insert the R-shaped pin into the insulator through the pin hammer, and the construction personnel can complete the operation alone, which greatly improves the work efficiency.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further.

The multi-functional pin puller for insulator R-type pin shown in Figure 1 includes pin puller hook (1), pin hammer (3), connecting rod (5) and operating handle (6), all of which are integrally formed of stainless steel.

The left end of the pin pulling pliers is provided with a pin pulling hook (1), and the lower end of the pin pulling hook (1) is a hook portion, and the hook portion is a downward pointed cone with a length of 40 mm. The upper part of the pin-pull hook (1) is bent 90° to the right to form a bent part, wherein the bent end is the fulcrum (2) of the hook part, which saves effort when pulling out the R-shaped pin. The other end of the bent part is connected with the bottom of the latch hammer (3).

The hammer face of latch hammer (3) is upward, and this hammer face is a flat circular hammer face, and its hammer face diameter is 10mm. The below of the pin hammer (3) and the hammer face is a hammer rod (4), and the length of this hammer rod (4) is 45mm, which is connected with the bending portion of the above-mentioned pin-drawing hook (1) at 20mm.

The right end of pin pulling pliers is operating handle (6), and by connecting rod (5), operating handle (6) is connected with the lower end of hammer bar (4) of latch hammer (3). The connecting rod (5) is a horizontal connecting rod (5), while the operating handle (6) is inclined upwards, and the connection angle with the connecting rod (5) is 150°. The operating handle (6) is flat and has a thickness of 4mm. At the same time, the upper end of the operating handle (6) is provided with a through hole (7), so as to facilitate the carrying and hanging of the pin pulling pliers.

When it is necessary to pull out the R-type pin in the insulator, extend the hook part of the pin-pull hook (1) into the pin opening at the upper end of the R-type pin, and the fulcrum (2) of the hook part is against the surface of the insulator, and then pull the pin-pull hook (1) The hook part of the hook is upturned, and the R-type pin can be pulled out quickly through the leverage.

When it is necessary to insert the R-type pin into the insulator, manually insert the R-type pin into the corresponding socket of the insulator, and then use the pin hammer (3) of the pin hook (1) to hammer down the R-type pin to fix it.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
