Description

Switch cover mechanism of railway rolling stock trackside image acquisition box body

Technical Field

The utility model belongs to the technical field of the rail transit, concretely relates to switch cover mechanism of railway rolling stock other image acquisition box of rail.

Background

In the process of using the railway train, the parts of the bogie at the bottom of the locomotive are generally monitored and detected in real time by ground trackside equipment at present, so that the defects and faults of the parts are judged, and the safety of railway transportation is guaranteed. In the monitoring and detecting technology, the defects and faults of parts are widely judged by adopting an image algorithm mode after a photographing camera collects pictures, so that the quality of the photographed and collected images needs to be clearer, and the phenomena of unclear stains and the like cannot occur. In an engineering field, the environmental conditions are quite severe, a lot of dust and fine particle suspended matters exist on the field, rainwater in rain and ice and snow in snow can be gathered on the surface of the camera lens, the surface becomes dirty along with the time, the shot pictures are very unclear, even the shot pictures have stains, and the later image algorithm cannot be used.

The existing processing method is generally characterized in that a protective collection box is arranged outside a camera lens, and one of the existing protective collection boxes adopts a cylinder to drive a switch cover to be opened and closed, but no air source is generally arranged on the site beside a railway section rail, so that the implementation of a matched engineering scheme is difficult; the other is that the switch cover adopts the rotation of the output shaft of the motor and drives the switch cover to rotate, the structure is complex, and the maintainability is poor.

Detailed Description

The present invention will be described in detail with reference to the following embodiments.

As shown in fig. 1, the utility model is arranged above the collecting box body 1, and comprises a door plate 2 and a driving mechanism for opening and closing the door plate 2;

the driving mechanism comprises an electric push rod 3, the electric push rod is an electric driving device which converts the rotary motion of a motor into the linear reciprocating motion of the push rod, and the electric push rod is mature in the prior art, small in size, high in precision, completely synchronous, good in self-locking performance, sanitary and directly driven by the motor; compared with a pneumatic actuating mechanism, the pneumatic actuating mechanism does not need an air source and an oil way of a pipeline, is easy to install and has the obvious advantage of energy conservation.

Two sides of the door panel 2 are respectively connected with the acquisition box body 1 in a sliding way through a linear sliding rail pair 7 so as to control the door panel 2 to open and close along a linear direction; the linear sliding rail pair is the existing mature technology and can support and guide the moving part to do linear motion; the guide mechanism has high guide precision, good wear resistance and sufficient rigidity and stability, is used in the linear reciprocating motion occasion, has higher rated load than a linear bearing, can bear certain torque, and can realize high-precision linear motion under the condition of high load; meanwhile, due to insensitivity to temperature change, the whole collection box is more easily suitable for severe environments such as severe cold, large temperature difference, hail and the like, so that high-quality railway locomotive brake pad images are obtained.

A piston rod of the electric push rod 3 is connected with a first spherical hinge 5, the first spherical hinge 5 is fixedly connected with the door plate 2 through a fixing frame 4, one end of the fixing frame 4 is fixed on the door plate 2, and the other end of the fixing frame is fixed with the first spherical hinge 5; the fixed end of the electric push rod 3 is fixedly connected with the collection box body 1 through a second spherical hinge 6; the spherical hinge adopts a spherical bearing structure, can flexibly bear the pressure from different surfaces, has the advantages of flexible and accurate control and large torsion angle, and is convenient to install and adjust, safe and reliable; the electric push rod is movably connected with the door plate through the spherical hinge, so that the push rod is not parallel to the sliding pair when the electric push rod is installed, and the clamping stagnation of the switch cover during movement is prevented;
