Abstract
The utility model discloses an anti-falling device of a traction motor, comprising a traction motor and a bogie that are connected with each other, wherein one end of the traction motor connected with the bogie is provided with a transverse clamping trough and a vertical clamping trough; the bogie is provided with a clamping device which corresponds to the vertical clamping trough; the bogie is also provided with an anti-falling plate installation base; the anti-falling plate installation base and the transverse clamping trough are internally clamped by the anti-falling plate; and a clearance is reserved between the anti-falling plate and the traction motor. In the utility model, the contact between the traction motor and the vehicle axle after the failure of the suspension connecting part of the traction motor is effectively avoided, the vehicle axle and the traction motor are effectively protected against damage and the running safety of the railway vehicle is improved.
Description
Technical field
The utility model relates to the block construction on a kind of rail traffic vehicles motor car bogie, after particularly a kind of suspension gear at traction electric machine lost efficacy, can avoid traction electric machine to be shed to traction electric machine anti-drop device on the track.
Background technology
Traction electric machine is the critical component of guideway vehicle, and it is suspended on the motor car bogie usually.Consider bogie truck be in operation the vibration frequency of operation height, impact load big, the safe suspension of traction electric machine must effectively be ensured.Usually the suspension gear of traction electric machine is except that having enough safety allowances, also will consider and install the safety measure that a sleeve anti-drop falls additional, promptly under the situation of tractive motor hanging component failure, the measure of traction electric machine slip-off preventing can continue the supporting traction motor, prevent that traction electric machine from falling on the track, thereby avoid the generation of safety misadventure.The common measure of traction electric machine anti-drop device is slip-off preventing arm of design above axletree, because the slip-off preventing arm has certain interval between vertical direction and axletree, the slip-off preventing arm does not contact with axletree when normally moving.
Typical frame suspension type traction electric machine anti-drop structure as shown in Figure 1 mainly comprises motor suspension seat 1 and motor mounting groove 2, tie bolt 3, traction electric machine 4, slip-off preventing arm 5, axletree 6 etc.This traction electric machine lateral rigidity is suspended on the bogie truck, traction electric machine one side is provided with motor mounting groove 2 and is used to embed motor suspension seat 1, opposite side is provided with slip-off preventing arm 5, traction electric machine is limited on wheel shaft 6 and the motor suspension seat 1, so both prevented the landing of traction electric machine and rolled, and again tie bolt 3 had been connected the harm that causes that comes off of inefficacy rear haulage motors and dropped to minimum.But this tractive motor hanging anti-drop structure is when traction electric machine comes off, and traction electric machine can contact with the axletree that rotates, and causes the damage of traction electric machine and axletree.
The utility model content
Technical problem to be solved in the utility model is, at the present traction electric machine problem that the rear haulage motor contacts with axletree that comes off, provide a kind of can be under the situation that tractive motor hanging lost efficacy, the novel traction motor anti-drop device that traction electric machine can not come in contact with the axletree that rotates.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of traction electric machine anti-drop device, comprise interconnective traction electric machine and bogie truck, this traction electric machine and bogie truck bonded assembly one end are provided with horizontal draw-in groove and vertical draw-in groove, this bogie truck is provided with and the cooresponding clip device of vertical draw-in groove, also be provided with anti-fall plate mount pad on the bogie truck, block the plate of setting up defences against in this anti-fall plate mount pad and the horizontal draw-in groove, leave the gap between anti-fall plate and the traction electric machine.
Described clip device is a C shape draw-in groove.
Compared with prior art; the beneficial effect that the utility model had is: the utility model is by offering horizontal draw-in groove and vertical draw-in groove at an end of traction electric machine; and correspondence is provided with clip device and anti-fall plate mount pad on bogie truck; block the plate of setting up defences against in this anti-fall plate mount pad and the horizontal draw-in groove; leave the gap between anti-fall plate and the traction electric machine; make the utility model not only simple in structure like this; reasonable in design; avoided contacting between suspension linkage member inefficacy rear haulage motor and the axletree simultaneously; actv. protection axletree and traction electric machine are not damaged, and have improved the safety of guideway vehicle operation.

The specific embodiment
As Fig. 2, Fig. 3 and shown in Figure 4, the utility model comprises traction electric machine 4 and bogie truck 10, one end of this traction electric machine 4 is fastened on suspension linkage member 7 on the bogie truck 10 by screw is installed, this traction electric machine 4 is provided with horizontal draw-in groove 8 and vertical draw-in groove 9 with bogie truck bonded assembly one end, this bogie truck 10 is provided with and the vertical draw-in groove 9 cooresponding clip devices of motor, adopt C shape draw-in groove 11 in the present embodiment, also be provided with anti-fall plate mount pad 12 on the bogie truck 10, block the plate 13 of setting up defences against in this anti-fall plate mount pad 12 and the horizontal draw-in groove 8, leave certain clearance between anti-fall plate 13 and the traction electric machine 4.This anti-fall plate 13 is square strip shape body, also is provided with anchor fitting on it.
When the utility model is assembled, the top that bogie truck 10 hangs with traction electric machine 4 in elder generation, and with the vertical draw-in groove 9 of traction electric machine 4 aim on the bogie trucks 10 C shape draw-in groove 11, make the upset degree of freedom of traction electric machine 4 restrained, so traction electric machine 4 can not overturn yet under the situation of suspension linkage member 7 fractures.Again traction electric machine 4 is vertically descended, up to the installation screw of traction electric machine 4 with after the corresponding installation screw of bogie truck 10 is aimed at fully, locking suspension linkage member 7.At last anti-fall plate 13 is inserted the anti-fall plate mount pad 12 from the end cross of traction electric machine 4; and insert it in the horizontal draw-in groove 8 of traction electric machine 4; leave certain clearance between anti-fall plate 13 and the traction electric machine 4; therefore can not work under these anti-fall plate 13 normal circumstancess; have only after suspension linkage member 7 fractures of traction electric machine 4; during traction electric machine 4 vertical drops; anti-fall plate 13 is just held traction electric machine 4; make traction electric machine 4 can not down continue motion; traction electric machine can not contact with axletree yet, can protect traction electric machine and axletree can not damage by actv..
