Technical Field

The invention relates to the field of anti-overturn devices of locomotives, in particular to a novel anti-overturn device.

Background

When the bridge inspection vehicle works, the gravity center deviates to the load increasing side relative to the track center, the load increasing side is provided with a compressed spring, the load reducing side is provided with a released spring, and the bridge inspection vehicle is not provided with an anti-overturning device inside the suspension.

Disclosure of Invention

In order to overcome the defect that the conventional locomotive is not suspended with an overturn-preventing device, the invention provides a novel overturn-preventing device.

The invention solves the technical problem by adopting the technical scheme that novel overturn-preventing devices comprise a shaft box body, a pressing mechanism, a framework mounting seat, a support, a lifting seat and an end cover, wherein the end cover and the lifting seat are respectively fixed on the shaft box body, the support is hooked below the lifting seat, the support is fixedly connected on the framework mounting seat, a cylinder body of the pressing mechanism is fixed at the bottom of a side beam of the framework, and the pressing mechanism is positioned above the shaft box body.

According to another embodiments of the present invention, step includes that the support is provided with a slot, the connection of the support hook is provided with an inclined plane , and the sliding-in surface of the lifting base is provided with an inclined plane two.

According to another embodiments of the present invention, step includes that the pressing mechanism is a hydraulic cylinder, and a pressing block is fixed to the end of a piston rod of the pressing mechanism.

According to another embodiments of the present invention, step includes fixedly coupling the lifting block to the end cap and the axle housing, respectively, via bolts.

According to another embodiments of the present invention, step includes the step of bolting the support to the frame mount.

According to another embodiments of the present invention, step includes the cylinder block of the hold-down mechanism being fixedly attached to the bottom of the frame side beam by bolts.

The anti-overturning device has the beneficial effects that the anti-overturning device slides in and is locked with the lifting seat when the support rises, and the shaft box body fixedly connected with the support is propped by the pressing mechanism, so that the anti-overturning purpose of the locomotive is realized.

The invention is further illustrated in the following description with reference to the figures and examples.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of the lifting base of the present invention;

FIG. 3 is a schematic structural view of the support of the present invention;

in the figure, 1, a shaft box body, 2, a pressing mechanism, 3, a framework mounting seat, 4, a support seat, 5, a lifting seat, 6, an end cover, 41, a clamping groove, 42, inclined planes and 43, and a second inclined plane are arranged.

Detailed Description

The technical scheme adopted for solving the technical problems is that the novel anti-overturning device comprises a shaft box body 1, a pressing mechanism 2, a framework mounting seat 3, a support 4, a lifting seat 5 and an end cover 6, wherein the end cover 6 and the lifting seat 5 are respectively fixed on the shaft box body 1, the support 4 is hooked below the lifting seat 5, the support 4 is fixedly connected to the framework mounting seat 3, a cylinder body of the pressing mechanism 2 is fixed to the bottom of a side beam of the framework, the pressing mechanism 2 is located above the shaft box body 1, a clamping groove 41 is arranged on the support 4, an inclined plane 42 is arranged at the connecting position of a hook of the support 4, an inclined plane two 43 is arranged at the sliding-in surface of the lifting seat 5, the pressing mechanism 2 is a hydraulic cylinder, a piston rod end of the pressing mechanism 2 is fixedly provided with a pressing block, the lifting seat 5 is respectively fixedly connected to the end cover 6 and the shaft box body 1 through bolts, the support 4 is fixedly connected to the side beam of the framework mounting seat 3 through bolts, and the pressing block 5 is fixedly connected to the side beam of the framework mounting seat 3 through bolts.

As shown in the attached figure 1, when the gravity center of the bridge inspection vehicle deviates to the load increasing side, the support 4 can ascend due to load reduction, and when the support 4 ascends to slide into a matching surface with the lifting seat 5 and then is locked, simultaneously, a piston rod of the pressing mechanism 2 (hydraulic cylinder) drives the pressing block to move downwards linearly until the pressing block is pressed on the top of the shaft box body 1, at the moment, is rigidly connected, so that the overturning moment is balanced, and the system is kept stable.

Referring to fig. 2 and 3, the inclined surface 42 of the support 4 and the second inclined surface 43 of the lifting base 5 can help the lifting base 5 to smoothly slide into the matching surface of the support 4, so that the support 4 can hook the lifting base 5, and the clamping groove 41 on the support 4 can match with the frame mounting base 3 to prevent the coupling bolt from failing due to abnormal load.
