Description

Technical Field

[0001] The utility model relates to a self-suspended opening and closing current collector protective cover bracket, belonging to the technical field of rail transit spare parts. Background Art

[0002] In rail transit, current collectors are needed to dynamically collect current to keep the vehicle running normally. In order to ensure the safety of the current collector, a current collector protection cover is usually set on the outside of the device. The current collector protection cover can prevent people from accidentally touching the current collector and causing danger, and can also prevent foreign objects from falling on the current collector and affecting normal operation.

[0003] The current collector protective cover is installed through the protective cover bracket. The current protective cover bracket is a fixed structure. After the protective cover is installed, the protective cover bracket cannot move the protective cover. However, in daily work, the current collector needs to be repaired. At this time, the current collector protective cover will affect the normal maintenance of the current collector. The current collector protective cover needs to be removed, which makes the maintenance work time-consuming, labor-intensive and inefficient. Utility Model Content

[0007] A further improvement of the present technical solution is as follows: the protective cover bracket comprises a bracket plate and a support plate; the support plate is perpendicular to the inner side of the bracket plate; an external protrusion is arranged at the lower end of the support plate, and a limiting protrusion is arranged on the bracket seat at a position corresponding to the external protrusion of the support plate, and the external protrusion cooperates with the limiting protrusion to realize the rotation limitation of the protective cover bracket.

[0008] A further improvement of the technical solution is as follows: two ear seats are arranged at the end of the bracket seat, and two ear seat plates are arranged at the lower end of the protective cover bracket; the ear seats and the ear seat plates are connected with each other using a damping shaft.

[0009] Due to the adoption of the above technical solution, the technical effects achieved by the utility model are:

[0010] The utility model provides a protective cover bracket with a split bracket seat and a protective cover bracket, and the bracket seat and the protective cover bracket are hingedly connected by a damping rotating shaft, so that the protective cover bracket can drive the current collector protective cover to freely suspend when rotating and opening and closing, and can stop at any position within the rotation range, which is convenient to use when inspecting and maintaining the current collector.

[0011] The utility model is provided with a positioning pin hook at the lower end of the shield bracket, and a positioning pin is correspondingly provided on the bracket seat. When the shield bracket is in a vertical state and is substantially perpendicular to the bracket seat 1, the positioning pin hook can be hooked on the positioning pin, and the positioning pin and the positioning pin hook are hooked to achieve the positioning of the shield bracket and prevent it from rotating.

[0012] The utility model provides an outer protrusion at the lower part of the shield bracket, and a position limiting protrusion is provided at the position corresponding to the outer protrusion at the end of the upper surface of the bracket seat. When the shield bracket is rotated to the vertical state, the outer protrusion abuts against the position limiting protrusion, and the abutment and cooperation between the two can prevent the shield bracket from excessive rotation, thereby realizing the rotation limit of the shield bracket.
