Abstract
The utility model discloses a naval vessel diesel engine drive chain extracting tool, including jack catch, bolt mandril and handle, a handle hole has respectively been seted up at the both ends of jack catch, and two screw holes have been seted up at the top of jack catch, two bolt mandril and jack catch threaded connection, the handle cartridge is on the jack catch. The utility model discloses a jack catch, bolt mandril and handle structure, when dismantling large -scale roller chain, low in labor strength, work efficiency are high, safe in utilization.
Description
Technical field
This utility model relates to machine tool technical field, particularly relates to a kind of ship diesel driving chain and tears open
Unload instrument.
Background technology
Chain conveyer is applied to including transport service, manufacturing industry, agricultural as a kind of important mechanical drive mode
Deng in interior various industries.In Chain conveyer, being most widely used of roller chain.
Roller chain is made up of inner plate, sleeve, roller, bearing pin, outer plate etc., its middle sleeve and inner plate
Interference fit, roller kink is on sleeve.Outer plate and bearing pin interference fit.Chain after a long time use,
The phenomenons such as abrasion, chain elongation relax easily occur, affects the accuracy that chain drive coordinates, affect equipment
Normal operation.In the replacing or maintenance process of chain, it usually needs peace of chain being dismantled and recombinates
Dress.And traditional chain method for dismounting mainly uses the instrument percussion bearing pins such as hammer, blunderbuss to be allowed to and outer chain
Plate separates.This method is when dismantling heavy-roller chain bar, and not only labor intensity is high, inefficiency, and
And hammering easily causes chain damage and personal security accident when skidding.
Utility model content
When this utility model is for tradition dismounting heavy-roller chain bar, labor intensity is high, inefficiency, and
And hammering easily causes chain damage and the problem of personal security accident when skidding, it is provided that a kind of use peace
Entirely, the ship diesel driving chain extracting tool that work efficiency is high.
For solving above-mentioned technical problem, the technical solution of the utility model is: ship diesel driving chain is torn open
Unload instrument, including claw, threaded mandrel and handle；The two ends of claw respectively offer a grip hole, claw
Top offer two screwed holes；Two described threaded mandrels are threadeded with claw；Handle is inserted into
On claw.
Preferably, claw has four paws.
Preferably, four paws is hook-type.
Preferably, the spacing of two screwed holes is equal with the bearing pin spacing on chain link.
Preferably, threaded mandrel is the hex bolts with socket cap.
Preferably, handle is cylindrical posts.
This utility model uses claw, threaded mandrel and grip structure, when dismantling heavy-roller chain bar, and labor
Fatigue resistance is low, work efficiency is high, uses safety.

Detailed description of the invention
As Figure 1-Figure 5, ship diesel driving chain extracting tool, including claw 1, threaded mandrel
2 and handle 3；Claw 1 is four paws hook-type, and the two ends of claw 1 respectively offer a grip hole, are used for making
Used time assigns handle 3, the top of claw 1 to offer two screwed holes, is used for installing threaded mandrel 2, and two
The spacing of individual screwed hole is equal with the bearing pin spacing on chain link；Two described threaded mandrels 2 and claw 1 spiral shell
Stricture of vagina connects, and threaded mandrel 2 is the hex bolts with socket cap；Handle 3 is inserted on claw 1, handle
3 is cylindrical posts.During use, claw 1 being put in the narrowest place of chain, hook-type position is placed under inner plate
Side.Mobile claw 1 makes threaded mandrel 2 align with the bearing pin on chain link to be dismantled.Screw threaded mandrel 2,
It is allowed to be close to the bearing pin on chain link, claw 1 hook-type position and inner plate clamping.Handle 3 is inserted into card
On pawl 1, tight with holding, it is allowed to move downward, by bearing pin by outer plate with spanner twisting threaded mandrel 2
Eject.
The above, only this utility model preferably detailed description of the invention, but protection model of the present utility model
Enclose and be not limited thereto, the technology model that any those familiar with the art discloses at this utility model
In enclosing, conceive in addition equivalent or change according to the technical solution of the utility model and utility model thereof, all
Should contain within protection domain of the present utility model.
