Be provided with circular arc end and the arc end crown the permanent magnet 41, it is described activity mandril 72 be made of insulating materials, it is described
Movable 72 tail end of mandril is arranged with metal sleeve, and the metal sleeve is connected with the upper elastic slice 73 ' and lower elastic slice 73 of arc, described
Upper elastic slice 73 ' connects another movable mandril 72 with lower 73 other end of elastic slice, by two movable tops when the permanent magnet 41 is mobile
Deformation occurs close to making elastic slice 73 ' with lower elastic slice 73 for bar 72, so that upper elastic slice 73 ' and the 71 ' phase of the second contact
Even, the lower elastic slice 73 is connected with the first contact 71.
In present embodiment, it is provided with line concentration portion 53 on the piston cylinder 5 and auxiliary piston cylinder 5 ' of the present apparatus, is set in line concentration portion 53
Be equipped with several conducting wires for by piston cylinder 5 and auxiliary piston cylinder 5 ' electromagnet 52, the first contact 71 and the second contact 71 ' with
Extraneous each related equipment is electrically connected.
In present embodiment, upper setting braking column 1 of the present apparatus on main drum clamps the brake using two panels braking vane 2
Car column 1 is to realize brake.Brake block 21 is set on braking vane 2, is made using the friction between brake block 21 and braking column
It is braked with realizing.And brake block 21 is that removably, therefore, the maintenance replacement in later period is more convenient.
In present embodiment, piston cylinder 5 and auxiliary piston cylinder 5 ' are respectively provided in the following above and of braking column 1.In work
It is provided with electromagnet 52 in plug tube 5, connecting rod 4 is set on braking vane 2, permanent magnet 41 is arranged in 4 end of connecting rod.Electromagnet 52 is led
Electricity, so that generating electromagnet attracts permanent magnet 41, this allows for permanent magnet 41 and drives connecting rod 4 mobile.And connecting rod 4 is connected with pressing plate
43, such that making braking vane 2 mobile, so that clamping braking column 1 realizes brake.
In present embodiment, after main drum stops operating, then braking column 1 is clamped always without braking vane 2.Therefore,
The electricity for disconnecting electromagnet 52, makes it no longer generate electromagnetic force.Then braking vane 2 sets back under the action of reset spring 42.
In present embodiment, after braking vane 2 no longer clamps braking column 1, the factor that limitation main drum rolls just is not deposited
At this point, it will cause accidents if unexpected rotation occurs for main drum.
In present embodiment, in order to avoid accident generation, the present apparatus is provided with gear 11 on braking column 1, and also sets
Tooth-strip part is set, tooth-strip part mate gear 11 engages.As long as rack gear is fixed, then gear 11 can not rotate, such that
Main drum is avoided to roll.
In present embodiment, the tooth-strip part of the present apparatus is located at the lower part in 6 middle section of locking plate, and locking plate 6 is installed on guide rod
On 62.62 tail end of guide rod is provided with support plate 621 and is used to support locking plate 6.Guide rod 62 is installed on cylinder 61, and cylinder
61 are mounted on bracket 3.The present apparatus also has limit spring 63, and limit spring 63 is in confined state, and its tail end top
Locking plate 6, be firmly pressed against in support plate 621.
In present embodiment, needing to lock main drum, when rolling it no longer, as long as 61 breakdown action of cylinder,
So that guide rod 62 is mobile, locking plate 6 is moved down, so that tooth-strip part and gear 11 engage.Because cylinder 61 is fixedly mounted at branch
On frame 3, and guide rod 62 can only be mobile in numerical value direction, so tooth-strip part can not move horizontally, so gear 11 is just locked,
It can not have rotated.Therefore, the present apparatus is achieved that the latch functions of main drum.
In present embodiment, when braking vane 2 and braking column 1 work, a large amount of heat can be generated, so that temperature liter
It is high.And after temperature is got higher, the abrasion of brake block 21 can be made to become faster, this will reduce service life.Also, the present apparatus is in sea
On use, after alluvion, some seawater are had on braking column 1, moisture evaporates under the irradiation of the sun, leaves behind
Salinity is attached to the surface of braking column 1.This can both make friction reduce, and influence braking quality, can also unstable wear.So this dress
It sets and is provided with air-jet device, for solving these problems.
In present embodiment, the braking vane 2 of the present apparatus is provided with puff prot, can for spraying gas to braking column 1
Enough coolings, additionally it is possible to blow away the salinity on its surface.Braking vane 2 is also provided with intake section 22, and the air for inputting air pump is defeated
It send to the puff prot.Also, when cleaning, directly intake section 22 can be connected with water pump, so that puff prot sprays
Effluent column realizes cleaning action on braking column 1.
In present embodiment, the present apparatus is additionally provided with the switch storehouse 7 of automatic booster air pump work and the portion of cooperating
Part.When permanent magnet 41 receives electromagnetic force influence and occurs mobile, it is adjacent to each other to will push movable mandril 72, so that upper elastic slice
73 ' deformation occurs with lower elastic slice 73, so that upper elastic slice 73 ' is connected with second contact 71 ', the lower elastic slice 73 and
One contact 71 is connected.Therefore the circuit of the first contact 71 and the second contact 71 ' turns on, therefore air pump will start to work,
It conveys in air to braking vane 2.
In present embodiment, in order to guarantee work quality, device of air is considered in the air inlet setting of air pump, air filtration is done
Only, it prevents impurity to be ejected on braking column 1, embraces the surface of braking column 1, the service life of the very high present apparatus.
In present embodiment, braking column is fixedly installed on the main drum of winch in the present invention, is braked to braking column
Operation, to protect winch ontology, improves service life；And it is also provided with gear in braking column, passes through rack pinion
Fit engagement work, then rack gear is carried out and is fixedly mounted, so that gear be avoided to rotate, therefore it can prevent main drum from surprisingly turning
It is dynamic, avoid accident.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims
Subject to, replacement, deformation, the improvement that those skilled in the art that any pair of this technology is made is readily apparent that each fall within of the invention
Protection scope.
