Description

Rotary pull-out type storage battery box

Technical Field

The utility model relates to a rail transit vehicle battery box especially relates to a rotatory pull-out type battery box.

Background

When the storage battery box of the existing rail transit vehicle maintains the storage battery, the storage battery and the electrode pole of the storage battery are exposed to the outside in the following modes:

(1) The storage battery is vertically installed, namely, the electrode pole of the storage battery is positioned at the top of the storage battery, and the opening surface of the storage battery box is positioned at the top of the storage battery box (closed or opened). When the storage battery needs to be maintained, the maintenance is directly carried out from the upper opening surface of the storage battery box, or the maintenance is carried out after the door plate of the top opening surface of the storage battery box is opened.

(2) The battery is mounted vertically, with the open face of the battery box (typically covered by a door panel) on the side of the battery box. When the storage battery needs to be maintained, the small bucket which is provided with the storage battery and is arranged in the storage battery box is pulled out in a translation mode through the sliding rail (the sliding rail is positioned at the bottom or two sides of the small bucket), and the storage battery and the electrode pole of the storage battery are exposed outside.

For example, chinese patent publication No. CN107887545a, "a storage battery box for rail vehicles", includes a guide rail of the storage battery, an outer revolving rail hinged to the guide rail is disposed at one side of the guide rail close to an opening end of the box door, a terminal stop block for preventing a trailer assembly from sliding out is disposed at an outer side of the outer revolving rail, and a first positioning hole is disposed at a side wall of the outer revolving rail; the gyro wheel support roof beam is equipped with second locating hole and one end and locates in it and rotatable bolt, and the other end and the cooperation of first locating hole of bolt carry on spacingly to dragging the slip of fighting the subassembly. Use the rail vehicle battery box that this patent discloses, carry out the backstop to the forward motion of trailer subassembly through setting up terminal backstop piece in the outside of outer turning track, prevent that the trailer subassembly from rolling out outside the turning track, the lateral wall at outer turning track sets up first locating hole, set up the second locating hole on the gyro wheel support roof beam, the two is fixed through the bolt, carry out the backstop with the backward motion to the trailer subassembly, prevent that it from removing on the chamber door, so that maintainer overhauls the battery and maintains, prevent the emergence of potential safety hazard.

(3) The battery is horizontally mounted, i.e. the electrode posts of the battery are located on the side of the battery, and the open face of the battery box (usually covered by a door panel) is located on the side of the battery box. When the storage battery needs to be maintained, the door plate is directly opened, and then the storage battery and the electrode pole of the storage battery are exposed outside.

Each of the three forms has its technical advantages and its disadvantages.

The first method is to mount the battery case in the vehicle mechanical room or above the vehicle floor, and cannot be used for under-vehicle mounting.

The second method is generally applied to the structure of the sliding rail, and the strength and the service life of the sliding rail or the door panel (on which the sliding rail is possibly arranged) have a negative effect; and the need for maintenance space is generally greater.

The battery box of the third aspect has a simpler structure (no additional bucket structure is required), and requires less space for maintenance than the second aspect. But the horizontal battery itself has a short life. The storage battery is installed under special conditions such as narrow installation space, and the structural style of the prior mature storage battery box is often not usable.

The battery bucket is rotated along the rotation shaft by a bearing assembly.

Further, stop gear is including installing in the battery box is located the inboard fixing base of the left and right sides lateral wall of door plant, the fixed surface of fixing base upper surface has the spacer pin, install the limiting plate on the left and right sides wall of battery fill respectively, the limiting plate with the mutual corresponding installation of spacer pin. Make the battery fill carry on spacingly after changeing out the battery box through stop gear, keep empting the state, the maintenance of being convenient for.

Specifically, an arc-shaped limiting groove is formed in the limiting plate, and the limiting pin is installed in the arc-shaped limiting groove.

Furthermore, the limiting mechanism further comprises a positioning pin arranged at the bottom of the storage battery bucket, and a positioning seat is arranged at the corresponding position of the storage battery box body. After the storage battery bucket is maintained and the vertical state is recovered, the vertical storage battery bucket in the vertical state is kept in a stable state by fixing the vertical storage battery bucket by using the positioning pin.

Further, in order to facilitate pulling out the storage battery bucket, a handle is installed on the side face, parallel to the door plate, of the storage battery bucket.

Compared with the prior art, the utility model discloses the beneficial effect who has does: the utility model discloses a rotate the mode that the battery was fought rather than the translation battery fill, expose battery and battery electrode utmost point post outside, maintain the battery. The use of a sliding rail structure is avoided, and the strength problem of the sliding rail or the door plate with the sliding rail is not worried about. And meanwhile, the requirement on the size of the maintenance space is smaller. The utility model discloses owing to innovated the form of battery box, avoided traditional battery box to need use the problem of costly and lower reliability that the slide rail brought.
