Abstract
The invention relates to a special lifting tool for hoisting the wheel center of a locomotive wheel pair. The special lifting tool is mainly used for solving the problem that according to a known way, the wheel center of a locomotive split wheel pair is hoisted by inserting an X type lifting tool into a hoisting tool, and can not be hoisted if the hoisting hole is not formed in a wheel disk for the wheel center. The lifting tool provided by the invention is a three-fork type hanger which is constituted by three lifting arms fixed on a sleeve, wherein upper and lower ends of the sleeve of the three-fork type hanger are connected on free end of a lifting ring through firm nuts respectively, the three lifting arms of the three-fork type hanger are connected with three movable connecting plates through cylindrical pins respectively, the other ends of the three movable connecting plates are connected with three claws through the cylindrical pins respectively, and the three claws are connected with a three-fork type support plate by the cylindrical pins via support points on the claws. The lifting tool provided by the invention is hoisted in a hoisting way adopting a wheel center inner hole, and the three claws of the lifting tool extend into the wheel center inner hole, so that the hoisting operation is very convenient; and furthermore, the space is saved and the working efficiency is improved.
Description
Technical field
Type of the present invention belongs to the technical field of the wheel pair repair of locomotives, is specifically related to the special hanger of a kind of train wheel core wheel lifting.
Background technology
The right core wheel of locomotive Split toothed wheel has two symmetrical holes for hoist under normal circumstances at core wheel disc place, X-type suspender is adopted to carry out lifting core wheel, but wheel holding is rolled to (or special individually DF4B wheel is right, and without hole for hoist on its core wheel disc, employing X-type suspender just cannot lift to DF8B; In addition, when Split toothed wheel is to disintegration, first long for strap core wheel and driven gear is returned together, then special moving back in gear frock, driven gear is returned from long core wheel.And original suspender is X-type core wheel suspender, it is mainly stuck on core wheel two hole for hoist by X-type pawl and lifts.But present situation is: move back gear frock limited space, when adopting X-type core wheel suspender, it is very inconvenient to operate, and with move back gear frock and produce and interfere, cannot lift.
Summary of the invention
The object of type of the present invention is that a kind of safety, the efficiency that design for the problems referred to above are high, the core wheel special hanger for hoisting of simple operation.
The technical solution of type of the present invention is: the special hanger of train wheel core wheel lifting to be the Trident Type suspension bracket of suspender be one hang three arms be fixed on sleeve and form, the upper and lower end of Trident Type suspension bracket sleeve is connected on the free end of suspension ring respectively by firm nut, three arms of Trident Type suspension bracket are connected with three active plates respectively by straight pin, the other end of three active plates is connected with three claws respectively by straight pin, and three claws are connected with Trident Type stay bearing plate with straight pin by the strong point on it.
The free end of the suspension ring described in the technical solution of type of the present invention is helicitic texture, and by the sleeve of suspension ring free end through Trident Type suspension bracket, Trident Type suspension bracket is fixed between two clamp nuts, and Trident Type suspension bracket can move up and down between two clamp nuts.
Trident Type suspension bracket described in the technical solution of type of the present invention is 120 ° of circle distribution by three arms, and be welded on a sleeve with the angle that axis is 30 °.
Active plate described in the technical solution of type of the present invention is a H type, and upper and lower two ends are provided with through hole in the horizontal direction, is connected between Trident Type suspension bracket and claw respectively with straight pin.
Trident Type stay bearing plate described in the technical solution of type of the present invention is 120 ° of horizontal circle distribution by three U-shaped yokes, the open end of U-shaped yoke is provided with through hole in the horizontal direction, is connected respectively with straight pin with the strong point on three claws.
Claw described in the technical solution of type of the present invention is a bending type, and claw is anti-pawl.
Type of the present invention adopts core wheel endoporus lifting mode to lift, and three of this suspender claws are put in core wheel endoporus, by connecting rod mechanism auto lock under the lift of driving, easy to operate, and saves space.Substantially increase wheel to the work efficiency disintegrated, core wheel lifts.The end of the screw thread suspension ring of type of the present invention is through in the sleeve of Trident Type suspension bracket, suspension bracket screws on two clamp nuts up and down, certain distance is left between Trident Type suspension bracket and two clamp nuts, Trident Type suspension bracket can move up and down between two nuts, when suspension ring are subject to the pulling force of driving a vehicle upwards, the nut of screw thread suspension ring lower end will withstand Trident Type suspension bracket and move up, due to link work, three claws receive the bearing force of pulling force obliquely and stay bearing plate, three claws will open automatically, form huge tension force, core wheel is lifted under the tension force of claw and the effect of friction force, when core wheel lands, time not by the pulling force of driving a vehicle upwards, three claws inwardly can shrink under the effect of self gravitation, automatically unclamp core wheel.So, there is automatic fastening function when this suspender is stressed, when not stressing, have the function of automatically shrinking.Type integral structure of the present invention is small and exquisite, adopt endoporus lifting mode, for the core wheel without hole for hoist, or picture to move back tooth frock this without lifting space, greatly can save space.The place in operation of type of the present invention significantly reduces the labour intensity of operator, makes employee's safety more convenient to operate, solves the difficult problem that core wheel cannot lift without hole for hoist.
