Embodiment Construction

[0012] Such as figure 1 , 2 As shown, the measuring tool of the present invention includes four parts: a hand grip bar 1, a fully open stop block 2, a closed position stop block 3, and a hook plate 4; the hook plate 4 is a plate shape, and one end of the hook plate 4 is provided with a The arc hook, the arc hook and the lower end surface of the hook plate 4 form an arc surface, and the shape of the arc surface is consistent with the shape of the inner surface of the No. 13 coupler to be tested. When in use, the arc surface of the hook plate 4 It can be fitted with the internal test of the coupler; the upper end surface of the hook plate 4 is a plane, and the other end of the hook plate 4 is fixed with a hand lever 1, which is connected with the hook plate 4 by welding, and the hand lever 1 is the control point during measurement. The hand grip 1 is made of GB / T14976, φ27×3.5 stainless steel tube; the upper end surface of the hook plate 4 is fixed with a full-open position sto...

Abstract

The invention discloses a two-car coupling car coupler three-state measuring tool, belongs to the technical field of rail cars, and particularly relates to a measuring tool for measuring three-state of a locking position and a full-opening position of a No. 13 car coupler when two-car coupling. The problems that in a current assembly and inspection process of the rail cars, the sizes of the locking position and the full-opening position of the No. 13 car coupler used when two-car coupling usually need to be measured, a current measurement method is to measure with a tape measure, the method has low efficiency and the precision cannot be guaranteed are mainly solved. A circular arc hook is arranged at one end of a hook plate of the measuring tool, and the circular arc hook and the lower endsurface of the hook plate constitute a circular arc surface. The upper end surface of the hook plate is a flat surface, a locking position stopping block and a full-opening position stopping block are fixed to the upper end surface of the hook plate, and a hand gripping bar is fixed to the other end of the hook plate. The measuring tool has a simple structure, light weight and convenient carrying, simple and convenient operation during measurement, high working efficiency and accurate measurement data.

Description

technical field [0001] The invention belongs to the technical field of railcars, and in particular relates to a measuring tool for measuring the three states of the No. 13 coupler locked position and fully open position used when two cars are connected. Background technique [0002] At present, in the field of rail car technology, as an important part of the two-car linkage, the No. 13 coupler plays the role of transmitting traction; in JW series catenary work vehicles, such as JW-4 catenary work vehicle; GC series traction rail car , such as GC270 traction rail car; GCY series heavy rail car, such as GCY450 heavy rail car; QGC series lifting rail car, such as QGC-25 lifting rail car, during the assembly process and inspection process of the rail car, it is usually necessary to check the No. 13 coupler Carry out the three-state inspection of the coupler, that is, when the lock position, the No. 13 coupler is 112-122mm; when it is fully open, the No. 13 coupler is 220-235mm. ...
