Abstract

The utility model discloses a vehicle declutch machine which is used to cancel brake work when a railway vehicle is in brake status, comprising a barred body 1 and a tail-hook 2, wherein the barred body 1 is a steel drill, the tail-hook 2 and the barred body 1 are connected to be an integration. When a vehicle needs to declutch, users only need to knock the head of a pawl 8 with the head of the barred body 1 to make the pawl 8 eject from the tooth slot of a pawl 10, then a brake axle 5 and a chain-coil 6 will revolve, a brake chain 7 and a brake rod 9 will release, and a brake-block will release the wheel, thereby brake is cancelled. The utility model has the advantages of safety, time-saving, convenience, and low price.

Description

The vehicle device that declutches

One, technical field

The utility model relates to a kind of instrument that is used for the railroad train shunting service, specifically is exactly to use the hand brake glancing impact when vehicle, is used for the instrument of brake off operation.

Two, technical background

Each joint railway carriage of load carrying vehicle all has a cover Pneumatic brake systems and a cover hand brake system in each that move on China railways at present.Pneumatic brake systems mainly is made up of braking reservoir, airduct, valve, release spring, brake lever, brake shoe, it is to enter the braking reservoir by the pressurized air in the airduct, promote the reciprocating motion of the pistons in the braking reservoir, the brake lever that moves through of piston drives brake shoe and holds tightly or unclamp wheel, thereby realizes that braking or brake off (being commonly called as alleviation) Pneumatic brake systems mainly use in the middle of train operation.Stop when train arrival need carry out the long period, or during the vehicle shunting service, particularly when locomotive with after railway carriage separates, owing to railway carriage has lost compressed-air actuated source, so Pneumatic brake systems just can't use.In order to prevent vehicle runaway voluntarily, must adopt the hand brake system.Hand brake system-system mainly is made up of braking handwheel, brake axle, pallet hammer, ratchet, ratchet, drum, drag chain.During left-hand revolution braking handwheel, drive drum by brake axle and rotate, drag chain and brake lever have been strained in the rotation of drum, and brake lever pulling brake shoe is held wheel tightly, reaches the purpose of braking.In order to keep braking mode for a long time, at the middle part of brake axle ratchet and pawl is installed, after glancing impact braking handwheel was tightened, ratchet snapped in the teeth groove of ratchet, and it is loosening to make it to circle round.Prior art problems occurs in when the needs brake off and (is commonly called as and removes lock), because the long-time stop of vehicle, compressed-air actuated discharge in the braking reservoir, make the pressure of release spring lose anti-perseverance (this process is commonly called as unintended release), this moment, ratchet increased suddenly to the pressure of ratchet, to such an extent as to can't the rolling brake handwheel with manpower, withdraw from ratchet, brake off.Owing to there is not special tool to withdraw from ratchet, the method one that present station operation personnel adopt is to pound ratchet with stone, and often handle breaks; Two are to use the hook of safety strap to pound, and so often cause the damage or the hidden danger of safety strap, cause safety misadventure; The 3rd, most of yard mans pull down the brake shoe pricker that train is using at present, prize ratchet with the brake shoe pricker, often throw away conveniently after using up, only the brake shoe pricker lost in 1 year of station, Hami just reaches up to a hundred more than according to statistics, this has not only caused waste, the more important thing is that because the brake shoe pricker is the part in addition that is used for installing and fixing brake shoe, the brake shoe pricker is removed and might causes train brake shoe in the middle of operation to come off, make brake failure, cause serious accidents such as collision, overturning.In addition, because the brake shoe of high-speed cruising drops into bounce-back behind the roadbed, may smash the reservoir, airduct of vehicle bottom etc., the safety that seriously jeopardizes vehicle.Also have above-mentioned three kinds of methods to have a common shortcoming to lose time exactly, because seek a suitable stone or dismantle the brake shoe pricker and all need the time, and these alternative tool operations that temporarily call in get up also very time-consuming, slow 2 minutes of imagination one joint railway carriage, a station will be wasted 3-5 hour in one day, be an enormous economic loss this today that density constantly increases that connects, dispatches a car at railway speed increase, station.

Three, summary of the invention

The purpose of this utility model provides and a kind ofly can guarantee safely, saves time, easy to carry, cheap vehicle declutches instrument.

To achieve these goals, the utility model vehicle device that declutches is made up of barred body and pintle, and barred body is a drill rod, and pintle and barred body are connected as a single entity.The another kind of vehicle device that declutches is made up of barred body, and barred body is a drill rod, is drilled with an aperture at the afterbody of barred body.

The declutch length of device of vehicle is: 15-30 centimetre, weight is the 250-500 gram

Declutch length the best of device of vehicle is 17 centimetres, and weight the best is 300 kilograms.

Adopted technique scheme, when needs declutch, only needed directly clash into the ratchet head with the barred body head, the ratchet head is deviate from from the ratchet teeth groove, the braking handwheel just can turn round, the take-off the brake chain, thus reach the purpose of brake off.

Because when operation only needs to hit ratchet head with the vehicle device that declutches, so it saves time, because it has avoided coming off of brake shoe, stone smashes staff and safety strap damages, so it has avoided train operation accident, has guaranteed safety; Because it can be made by a reinforcing bar, so it is cheap; Because its afterbody is shaped on crotch, aperture, can hang on the safety strap, so it is easy to carry.

Five, the specific embodiment

The utility model is further described below in conjunction with the drawings and the specific embodiments:

In Fig. 1 and Fig. 2, the vehicle device that declutches is made up of barred body 1 and pintle 2.Barred body 1 is a drill rod, and pintle 2 and barred body 1 are connected as a single entity.The width of pintle 2 is 1～2 centimetre, and thickness is 1～3 millimeter.Obviously this device that declutches can at high temperature be forged its afterbody to beat and make that it attenuates, attenuation with a drill rod, and bending forms then.

In Fig. 3 and Fig. 4, the another kind of vehicle device that declutches is made up of barred body 1, and barred body 1 is a drill rod, is drilled with an aperture 3 at the afterbody of barred body 1.The declutch length of device of vehicle can be 35～55 centimetres, best centimetre; Weight can be kilogram, and the best is a kilogram.

In Fig. 5, when needs glancing impact left-hand revolution braking handwheel 4, drive chain drum 6 rotations, thereby, just wheel is held tightly with the brake shoe that brake lever 9 links to each other with drag chain 7 and lever connection 9 tensions by brake axle 5, realized braking.The effect of ratchet 8 and ratchet 10 is to prevent brake axle 5 and chain drum 6 reversings, to keep braking mode.When the needs brake off, only need directly clash into the head of ratchet 8 with barred body 1 head, it is deviate from from the teeth groove of ratchet 10, brake axle 5 and chain drum 6 will turn round, and drag chain 7 and lever connection 9 will loosen, and brake shoe unclamps wheel, thus brake off.
