Description
Technical Field
The invention relates to an electric power operation and maintenance tool, in particular to a pin disassembling device.
Background
The workload of repairing, testing and replacing the devices such as the disconnecting switch and the circuit breaker in the transformer substation is more and more, pins such as a cotter pin, a cylindrical pin, an expansion pin and a taper pin which are used as common tools are widely applied, and a large amount of pins are required to be disassembled when the devices such as the disconnecting switch and the circuit breaker are repaired.
The influence of environment and position causes that the pin is difficult to disassemble or can be disassembled only by consuming a large amount of manpower and time. The time for disassembling a rusted pin or a pin with a poor position is 1.5-2 hours, so that the working efficiency is reduced, the power failure time of equipment is prolonged, the economic benefit is influenced, and the reliability and the safety of power supply are also reduced.
At present, the pin in the switch station is not removed, and the pin can only be detached by means of other technologies, such as pliers and the like, but the pin is not convenient to use and is low in detaching efficiency.
Disclosure of Invention
The invention aims to solve the technical problem of providing a pin dismounting device for multifunctional equipment for electric power operation and maintenance, which is convenient for dismounting a pin in a switching station.
In order to solve the technical problems, the invention adopts the following technical scheme: electric power fortune dimension overhauls multi-functional equipment and tears round pin device open, including handle, slide bar, sliding hammer, atress adapter sleeve, connecting rod and instrument head, handle threaded connection is in the slide bar rear end, atress adapter sleeve threaded connection slide bar and connecting rod, the front end threaded connection instrument head of connecting rod, the instrument head is including the dismantlement hook that is used for dismantling the split pin, the movable nestification of sliding hammer is on the slide bar for thereby it drives slide bar, connecting rod, dismantlement hook effect on the split pin to slide backward and strike the handle.
Optionally, the disassembly hook is made of alloy tool steel.
Optionally, the handle, the sliding rod, the sliding hammer, the stressed connecting sleeve and the connecting rod are made of 45 steel.
Optionally, the handle is of a hammer-shaped structure.
Optionally, the sliding hammer includes a middle projection, flange portions at both ends, and a recess portion connecting the flange portions and the projection.
By adopting the technical scheme, the invention has the following beneficial effects:
1. hold the slip hammer and slide along the slide bar, the slip hammer moves to the handle, receives the resistance, and the slip hammer impact force acts on the handle, through handle, slide bar, connector, dismantlement hook effect at the split pin, the split pin receives the power of upwards pulling out, very easy dismantlement is successful.
2. The handle, the sliding rod, the stress connecting sleeve, the connecting rod and the tool head are in threaded connection, and can be conveniently disassembled and placed in a tool box, so that the tool is convenient to carry.
3. The tool head can adopt the disassembly hook of the split pin, and can be replaced by other functional structures, so that multiple functions are realized.
The following detailed description of the present invention will be provided in conjunction with the accompanying drawings.
Drawings
The invention is further described with reference to the accompanying drawings and the detailed description below:
FIG. 1 is a schematic structural diagram according to a first embodiment of the present invention;
fig. 2 is a schematic structural diagram of a second embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
