Abstract

The utility model discloses an universal steering frame of rail transport vehicle, including the wheel frame, be equipped with the wheel on the wheel frame, the supporting box dress is on the wheel frame, is equipped with universal bulb on the supporting box and turns to the subassembly, universal bulb turn to the subassembly and include the bulb axle, bulb axle dress is on the supporting box, is equipped with down apron and upper cover plate on the bulb of bulb axle, apron and upper cover plate pass through bolted connection down. The utility model discloses there is following technological effect: the rail transport vehicle with the universal steering frame can be adaptive to the rail with fluctuant roadway, small-radius curve and small-radius slope, variable rail gauge and large rail surface height difference, the rail clamping device can be adaptive along with the rail, and can be well adaptive on the slope of the small-radius curve, so that production accidents such as the rail clamping device and the rail are blocked or cannot be clamped to derail are avoided.

Description

Universal steering frame of rail transport vehicle

Technical Field

The utility model relates to an universal frame of rail transport car.

Background

In the mine auxiliary transportation field, the rail transport vehicle is provided with a rail clamping device for limiting the rail, so that the safety is improved and the rail transport vehicle is widely adopted. Due to the complex mine geology, the phenomena of fluctuation, sharp turning, sharp slope change, track gauge change, unparallel track surfaces of two supporting tracks, unequal heights and the like exist in the laid tracks. The rail clamping device of the conventional rail transport vehicle with the rail clamping device is arranged on the underframe of a carriage to realize rail clamping, and the rail transport vehicle has poor passing capability when facing a roadway with a turn, and particularly cannot pass under the condition that the wheelbase of the vehicle frame is longer or faces a curve or a ramp with a small radius; the relative motion amplitude of the carriage relative to the track is large, so that the vehicle generates interference during running; the rail clamping devices are fixedly connected to the bogie but cannot be correspondingly adjusted along with the track, or the rail clamping devices are arranged at two ends of the bogie, so that the distance between the two rail clamping devices is large, and the trafficability of small-radius slope change or turning is reduced; when the rail transport vehicles of the types face a rail system with a complex situation, the rail clamping device cannot be self-adaptive along with the rail, or cannot be well self-adaptive on a slope change of a small-radius curve, so that production accidents such as the rail clamping device and the rail are blocked or cannot be clamped and derailed are easily caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an universal steering frame of rail transport car.

The technical scheme of the utility model, a universal steering frame of rail transport vehicle, including the wheel frame, be equipped with the wheel on the wheel frame, the supporting box dress is on the wheel frame, is equipped with universal bulb on the supporting box and turns to the subassembly, universal bulb turn to the subassembly and include the bulb axle, the bulb axle dress is on the supporting box, is equipped with down apron and upper cover plate on the bulb of bulb axle, lower apron and upper cover plate pass through bolted connection.

And a supporting spring is arranged on the lower side of the lower cover plate of the universal ball head steering assembly.

The supporting box body is arranged on the wheel frame through a rotating shaft.

The utility model discloses there is following technological effect: the rail transport vehicle with the universal steering frame can be adaptive to the rail with fluctuant roadway, small-radius curve and small-radius slope, variable rail gauge and large rail surface height difference, the rail clamping device can be adaptive along with the rail, and can be well adaptive on the slope of the small-radius curve, so that production accidents such as the rail clamping device and the rail are blocked or cannot be clamped to derail are avoided.
