Abstract
A tool for replacing a coupler knuckle of a coupler of a railway wagons comprises a base trolley, a rotating hand wheel, transmission gears, lifting double-screw bolts and coupler knuckle fixtures, wherein the transmission gears are three gears, which are completely as same as each other, engaged with each other and mounted on a platform of the base trolley; the rotating hand wheel is mounted on one transmission gear; the two lifting double-screw bolts are arranged on the other two transmission gears and can rotate with the transmission gears; and the coupler knuckle fixtures are mounted on the lifting double-screw bolts and can be used for clamping a knuckle at the front end of the coupler knuckle of the coupler. The tool for replacing the coupler knuckle of the coupler of the railway wagons, provided by the invention, has the advantages of simple structure, low cost, safety, high efficiency and convenience in use. As the motion of the rotating hand wheel is converted into the motion for stably lifting the coupler knuckle of the coupler upwards, the force for lifting the coupler knuckle upwards is reduced and the part is very stably moved to a desired height. Meanwhile, as the platform of the tool is both an operation platform in the operation of personnel and a tool for transporting materials by using railway tracks, the wagons are convenient to overhaul.
Description
Technical field
The present invention relates to a kind of instrument changing coupler knuckle of car coupler of railway freight car.
Background technology
For guaranteeing railway operation safety, vehicle coupler tri-state is bad, wear away and excessive etc. must to overhaul or change when affecting safe train operation, and the maintenance of hitch often relates to plucking of hook tongue and separates and install.Because of hook tongue heavily about 35KG, generally needed 2 people to lift when changing hook tongue or use certain vehicle to be transported to fault hitch place in the past.When changing hook tongue due to the height of hook tongue horizontal centre line-spacing rail surface under complete vehicle curb condition, lorry is (880 ± 10) mm, and hook tongue is heavier, hook tongue can be risen to specified altitude assignment against certain inertia by the physical strong person of general needs, very easily cause personal injury once the factors such as hand cunning cause hook tongue to drop, in operation, there is larger potential safety hazard.And the research lacked both at home and abroad at present in this respect, mostly still adopt clumsy old stuff pattern when overhauling hitch, not only have security risk but also efficiency not high.
Summary of the invention
The object of the invention is for row inspection or car inspection and maintenance personnel provide a kind of easy to operate, the high car body of safety changes the instrument of coupler knuckle of car coupler of railway freight car, it can effectively solve row inspection person the old stuff pattern maintenance hitch of clumsiness time inconvenience.
Realizing the technical scheme that the object of the invention takes is: it is made up of base dolly, rotation hand wheel, transmission gear, lifting stud, hook tongue fixture, and base dolly is made up of wheel and platform, and wheel can roll on rail; Transmission gear is made up of three identical gears, and intermeshes, above the platform being arranged on base dolly; Rotation hand wheel is arranged on one of them transmission gear, and two lifting studs are located on two other transmission gear, and can rotate with transmission gear; Hook tongue fixture is made up of supporting plate, vertical baffle and bumping post, two tapped bore of supporting plate above it are arranged on lifting stud, vertical baffle is arranged on side between two lifting studs, bumping post is located at opposite side between two lifting studs, and the tongue of coupler knuckle for car coupler front end just can be blocked in the space that vertical baffle and bumping post are formed.
The invention has the beneficial effects as follows: structure is simple, with low cost, safe and efficient, easy to use; Utilize rotation hand wheel to move, convert the motion steadily upwards promoted by coupler knuckle for car coupler to, both decreased the power of upwards hoist hook tongue, very reposefully parts are delivered to again the height of needs; Meanwhile, the job platform when platform of this instrument is human users, is again the instrument utilizing railroad track transporting material, facilitates car inspection and maintenance.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention; Accompanying drawing 2 is using state figure of the present invention.
Detailed description of the invention
As shown in Figure 1 and Figure 2, it is made up of base dolly, rotation hand wheel 3, transmission gear 1, lifting stud 4, hook tongue fixture, and base dolly is made up of wheel 8 and platform 7, and wheel 8 can roll on rail; Transmission gear 1 is made up of three identical gears, and intermeshes, above the platform 7 being arranged on base dolly; Rotation hand wheel 3 is arranged on one of them transmission gear 1, and two lifting stud 4 bottoms are fixed on two other transmission gear 1, and can rotate with transmission gear 1, and lifting stud 4 adopts the stud of diameter 50mm; Hook tongue fixture is made up of supporting plate 2, vertical baffle 5 and bumping post 6, supporting plate 2 is that the trapezoidal of 20mm or oblong steel plate are made by thickness, supporting plate 2 there are two tapped bore, and two tapped bore above it are arranged on lifting stud 4, vertical baffle 5 is arranged on side between two lifting studs 4, bumping post 6 is located at opposite side between two lifting studs 4, and the tongue of coupler knuckle for car coupler 9 front end just can be blocked in the space that vertical baffle 5 and bumping post 6 are formed.
Its working process and principle of work are: put into the supporting plate 2 of hook tongue fixture by coupler knuckle for car coupler 9 above lifting stud 4, the tongue of coupler knuckle for car coupler 9 front end is stuck in vertical baffle 5 and is formed spatially with bumping post 6, rotate the transmission gear 1 that rotation hand wheel 4 drives its underpart, by three transmission gears 1, power is delivered on two lifting studs 4, lifting stud 4 rotates the power power of rotation be converted to upwards, the supporting plate 2 of hook tongue fixture is driven upwards to promote reposefully, thus coupler knuckle for car coupler 9 is risen to the height of needs, the position of adjustment coupler knuckle for car coupler 9, be installed on the hitch of maintenance, after installing, contrarotation rotation hand wheel 3 makes hook tongue fixture decline, coupler knuckle for car coupler 9 can be taken off from fixture.
