Technical Field

The utility model belongs to the technical field of EMUs car end is connected, more specifically relates to a split type frame construction of closing mechanism, closing mechanism.

Background

The opening and closing mechanism is used as an important component of a head type of the motor train unit, and has the main functions of: the running wind resistance is reduced, and the energy consumption loss is reduced when the train runs at a high speed; rain water and foreign matters are prevented from entering the interior of the hood, and front-end equipment of the vehicle body is protected; when the train needs to be subjected to reconnection marshalling or traction rescue, the car coupler is exposed, the train is connected, in addition, the appearance integrity of the train can be improved, and the train is more attractive.

At present, the existing opening and closing mechanisms of the motor train unit are all cabin doors connected with rotating arms, and the rotating arms rotate around rotating shafts so as to realize opening and closing actions of the cabin doors. Because of the structural characteristics of the cabin door, an upper rotating arm and a lower rotating arm need to be arranged on each cabin door and respectively rotate around an upper rotating shaft and a lower rotating shaft to complete the movement of the cabin door, and in order to ensure that the opening and closing actions of the cabin door are stable and are not blocked and the cabin door can move according to a designed track, the upper rotating shaft and the lower rotating shaft are required to have extremely high position precision, aperture precision and coaxiality requirements. Because the frame structure is large, the distance between the upper and lower rotating shafts and the hole matched with the upper and lower rotating shafts is far, which often brings great difficulty to processing, so that a structure is urgently needed to be designed, the requirement of the opening and closing mechanism on the precision of the rotating center can be met, and meanwhile, the production department can easily execute the structure.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a satisfy split type frame construction of closing mechanism, closing mechanism of upper and lower center of rotation high accuracy coaxial, the easy assembly.

In order to achieve the technical purpose, the application adopts the following specific technical scheme:

the utility model provides a split type frame construction of closing mechanism, the frame divide into upper and lower two-layer, and upper and lower layer frame contains two rotation centers respectively, upper frame and lower floor frame constitute an integral frame.

Furthermore, the upper frame main body is of a convex structure, and a left upper rotating center and a right upper rotating center are arranged on a cross rod at the front part of the upper frame main body and are respectively provided with two upper rotating arms.

Furthermore, a connecting rod is fixedly arranged at the front end of the upper layer frame body.

Furthermore, a plurality of mounting wings are arranged at the rear part of the upper layer frame main body and are used for being mounted to a vehicle body.

Furthermore, the lower frame main body is of a convex structure, and a left lower rotating center and a right lower rotating center are arranged on a cross rod at the front part of the lower frame main body and are used for respectively mounting two lower rotating arms.

Furthermore, a plurality of mounting wings are arranged at the rear part of the lower-layer frame main body and are used for being mounted to a vehicle body.

Furthermore, the coaxiality of the upper and lower rotating centers of the opening and closing mechanism can be ensured by adjusting and assembling the upper and lower layers of frames.

Further, an opening and closing mechanism is further provided, and the split type frame structure is adopted.

The frame of the existing opening and closing mechanism is of an upper-lower integrated frame structure, the relative position of an upper rotating center and a lower rotating center is not adjustable, and the frame structure is large, so that the novel outstanding beneficial effects are as follows:

(1) the weight of the frame structure of the opening and closing mechanism is reduced;

(2) the processing difficulty of the frame is reduced, and the coaxiality of the upper and lower rotating centers is improved;

(3) the hatch door rotating arm is easier to assemble;

(4) the upper and lower coaxiality is improved, so that the opening and closing of the hatch door of the opening and closing mechanism are more stable.
