Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an engine battery fixing device that allows a battery that supplies electric power to a starting motor or the like to be easily exposed or removed from an equipment frame.

[Problems to be Solved by the Prior Art and Ideas] As is well known, a motor generator or the like having a built-in starter motor is equipped with a battery for driving the starter motor.

This kind of batsuteri is, for example,
As disclosed in the above publication, many of them are directly mounted and fixed on the base frame of the equipment. By the way, this battery is generally stored in a narrow space surrounded by the engine body, generator, muffler, etc. During regular inspections, check the amount of water loss in the electrolyte of this battery. It is difficult to replenish the electrolyte or measure the specific gravity of the electrolyte.

Further, the battery is relatively heavy, and the task of replacing the battery, which is housed in such a narrow space, is complicated.

Furthermore, for example, in Japanese Utility Model Application Publication No. 58-92868,
A base frame is installed protruding from the side of the equipment frame,
A technique has been disclosed in which a battery is placed and fixed on this base frame so that the battery can be easily replaced from the outside.

However, since the battery always protrudes from the side of the equipment frame, there is a problem that it is easy for an operator to accidentally touch it.

In order to deal with this, Japanese Utility Model Publication No. 58-27482 makes it possible to pull out the stand on which the battery is placed on the front of the battery storage box, and further provides a cart on the front of the battery storage box to place the pulled-out stand. It has a structure that allows it to move in a direction perpendicular to the direction of movement of the pedestal. However, in order to expose the battery outside the equipment frame during maintenance and inspection of the battery, pull out the pedestal on which the heavy battery is placed from the battery storage box, place the pedestal on which the battery is placed on a trolley, and then The problem is that the cart must be moved, resulting in poor workability, and that a large number of bearings are required to reduce sliding resistance when moving the cart, resulting in a large number of parts.

Furthermore, in Japanese Utility Model Publication No. 58-11635, one side surface of the lower frame of the battery carrier is supported vertically and rotatably relative to the corresponding side surface of the upper frame, and the other side surface of the lower frame is supported vertically and rotatably. The battery can be taken in and out from below. However, there is a problem that it cannot be used in a device where the battery is disposed below and there is no space below.

[Purpose of the invention] The present invention was developed in view of the above circumstances. When a battery is exposed outside the equipment frame during periodic inspections, there is no need to hold the battery, improving work efficiency, and reducing the amount of electrolyte. Not only can specific gravity measurements and water replenishment be easily performed, but batteries can also be easily replaced, and in normal conditions, batteries can be stored in a narrow space without protruding from the equipment frame. It is an object of the present invention to provide a battery fixing device for an engine that can be applied even when the battery is disposed below and there is no space below.

[Means for Solving the Problems] In order to achieve the above object, an engine battery fixing device according to the present invention fixes a battery within an equipment frame that houses and supports the engine. The base on which the battery is placed and fixed is supported so that it can be rotated horizontally via a shaft member and can be freely retracted from the equipment frame, and when it is rotated to the outside of the equipment frame, it is grounded to the base and leveled. It is provided with legs that maintain the state and legs that are sealed to the equipment frame.

[Operation] With the above configuration, under normal conditions, the base on which the battery is placed and fixed is housed within the equipment frame. When removing the battery during periodic inspection, etc., the base is rotated horizontally via the shaft member.

Then, the base protrudes to the outside of the equipment frame, and the battery mounted and fixed on the base is exposed outside the equipment frame. Further, the legs provided on the base are grounded, and the legs are further sealed to the equipment frame to support the base at three points.
