Abstract

The utility model relates to a tool for removing a socket at one end of an insulator on an overhead electric high-voltage cable, in particular to a socket removing device. A defective insulator only can be replaced by two people climbing up to both ends of the insulator to be replaced with a common tool via matched operation in the prior, which has the defects of time and labor consumption and low efficiency. The utility model adopts the technical scheme that a gear shaft is mounted inside a casing, a hooked gear rack penetrates through the casing and is meshed with a gear on the gear shaft, a Y-shaped fork is arranged on the casing in the same direction with the hook part of the hooked gear rack, and the distance from the Y-shaped fork to the hooked gear rack equals to that from the sockets at the two ends of the insulator to the steel cap. Therefore, only one person is required to remove the sockets at the two ends of the insulator and then replace the defective insulator.

Description

Take off a bowl device

Technical field

The utility model relates to the instrument of earth potential live dismounting insulator one end bowl head, particularly a kind of bowl device that takes off.

Background technology

Run into the insulator difficult problem that charged for replacement damages through regular meeting on the electric power overhead high-voltage line; insulator one end connects the bowl head; the other end connects the steel pin; change the insulator that damages and at first just must pull down the bowl head of insulator one end; because each factory's model of insulator, creepage ratio distance, shape differ; traditional way adopts the common bottle hook that takes off exactly, can tear any more bowl head open and just must adopt an equal potential working, time-consuming during operation, effort, inefficiency.

The utility model content

The utility model purpose provides and a kind ofly saves time, laborsaving, simple and effective take off a bowl device.

Realize this purpose and take technical scheme: a kind of bowl device that takes off, one gear shaft is installed in shell, the buckle tooth bar passes shell and is meshed with gear on the gear shaft, on the equidirectional shell of the hook portion of buckle tooth bar, be fixed with Y shape fork, between Y shape fork and the buckle tooth bar between distance and insulator steel cap and the bowl apart from identical;

Y shape fork is arranged in close gear shaft input on the shell, and the buckle tooth bar is arranged in the other end on the shell;

Y shape fork is taked movable connection method with shell, and promptly Y shape fork can be according to distance between insulator Height Adjustment and the buckle tooth bar;

Gear shaft is installed in the shell by rolling bearing.

The utility model technique effect: use bowl head on the utility model dismounting insulator, people's earth potential can be finished, and the bowl head needed equal potential working on the insulator and do not tear open any more, therefore time-consuming, effort, inefficiency in the past.Because it is also more time saving and energy saving to be that specific purpose tool uses, operating efficiency is enhanced about more than once.

Description of drawings

Accompanying drawing is the utility model structural representation.

1 is the gear shaft input among the figure, and 2 is shell, and 3 is the gear on the gear shaft, and 4 is gear shaft, and 5 is the tooth bar on the buckle tooth bar, and 6 is the buckle tooth bar, and 7 is the hook portion on the buckle tooth bar, and 8 are Y shape fork.

Embodiment

The utility model Y shape fork is propped up insulator one end steel cap, hook portion on the buckle tooth bar is hooked insulator one end bowl head, be connected with the gear shaft input with the insulation hook stick, rotating insulated hook stick just can rotate by the driven gear axle, gear shaft by its cog with the buckle tooth bar on the tooth bar engagement, drive the buckle tooth bar and move, hook portion hook jail insulator one end bowl head on the buckle tooth bar, along with the continuation of insulation hook stick rotation, insulator one end bowl head will come off promptly replaceable new insulator.

Insulation hook stick and gear shaft input employing engage thread is connected, and the rotating insulated hook stick hook stick of can realizing insulating is connected with the gear shaft input.By the rotating insulated hook stick of a people is bowl head on the detachable insulator, finishes the insulator work that more renews, and saves the multiple unfavorable factor of equipotential operation, and work safety efficient is enhanced about more than once.

Claims

1, a kind of bowl device that takes off, it is characterized in that: a gear shaft is installed in shell, the buckle tooth bar passes shell and is meshed with gear on the gear shaft, on the equidirectional shell of the hook portion of buckle tooth bar, be fixed with Y shape fork, between Y shape fork and the buckle tooth bar between the bowl head at distance and insulator two ends and the steel cap apart from identical.

2, according to the described a kind of bowl device that takes off of claim 1, it is characterized in that: Y shape fork is arranged in close gear shaft input on the shell, and the buckle tooth bar is arranged in the other end on the shell.

3, according to claim 1 or 2 described a kind of bowl devices that take off, it is characterized in that: Y shape fork is taked movable connection method with shell.

4, according to claim 1 or 2 described a kind of bowl devices that take off, it is characterized in that: gear shaft is installed in the shell by rolling bearing.
