2. Description of the Related Art In general, a self-propelled small-sized working machine of this type obtains working or running energy directly by an engine or indirectly by electric power generated by the engine. Therefore, in order to start the engine or charge the power output obtained from the engine, the battery is mounted in a portion relatively close to the engine, that is, in the engine room.

[0003]

The battery of this type of self-propelled working machine is provided in the engine room like a car, but this working machine cannot sufficiently receive cooling air like a car. Since the vehicle does not travel as much as possible, the ventilation of the engine room is not good, and there is a problem that the battery becomes hot and the durability is reduced. In order to solve such a problem, it is considered that a battery is provided at the forefront of the engine room and a fan driven by the engine forcibly sucks air into the engine room to prevent the battery from rising in temperature. However, in practice, the engine room was so small that the batteries could not be arranged in the engine room, and the batteries were often exposed to high temperatures and the durability was often reduced.

The power shovel 1 has a crawler belt 2 for traveling on the left and right sides of the body, and has a body frame 3 supported by the crawler belt 2. A ground leveling blade 4 is supported on the body frame 3 so that the base end thereof can rotate, and is configured to be able to move up and down by a hydraulic blade cylinder 4a.

[0007] A swing frame 5 is pivotably supported above the body frame 3. The swing frame 5 is assembled in a box shape by welding side plates between two upper and lower steel plates including an upper plate 6c and a bottom plate 6b. In the center of the upper surface of the swing frame 5, a driver's seat 5 is provided.
a and a console 5b are arranged, and further in front thereof, a shovel mechanism 5c supported by a boom 5j is arranged,
An engine (not shown) covered by a hood 5d is disposed at the rear. 5e is a sunshade roof for the driver. Note that the shovel mechanism 5c shown in FIG. 1 does not differ greatly from the conventionally known one, and therefore detailed description is omitted.

As shown in FIG. 2, the seat 5a is configured to be slidable in the front-rear direction on a rail 8b provided on a seat stand 8a and to be capable of being temporarily locked at a desired position. Reference numeral 8c denotes a lever for releasing the lock so as to slide the seat 5a back and forth. The mechanism for moving the seat 5a back and forth or locking it at a desired position is similar to that of a commercially available passenger car, and a detailed description thereof will be omitted.

The seat 5a has an armrest 8d only on the left side.
Is provided. The armrest 8d is provided independently of the seat 5a, and the stay portion is provided with a guard pipe 5f described later.
In addition, the handle 8 is also used as a handle 8 for making it easier for the driver to climb from the ground to the driver's seat. That is, the attachment of the handle 8 is shown in a portion surrounded by a two-dot chain line in FIG. As shown in an enlarged manner in the drawing, in the L-shaped portion composed of a side plate portion 8f forming the seat base 8a and a horizontal portion 8j bent outwardly in the horizontal direction from the side plate portion 8f, the rail 8 is bolted by the bolt 8k.
b. As a result, the stay portion of the armrest forming the handle 8 is reinforced by the seat rail 8b, so that a desired strength can be obtained without increasing the thickness of the side plate portion 8f forming the seat stand 8a. In addition, the number of parts is reduced as compared with the case where an armrest and a handle are separately provided, and at the same time, the area around the driver's seat is made compact and usability is obtained. 8e is a fuel tank for the engine.

In front of the seat 5a, a guard pipe 5f is installed in a gate shape in front of the operation console 5b.
Immediately behind, that is, as shown in FIG.
A battery 7 is accommodated in front of the left hand of the driver sitting on the vehicle. As shown in FIG. 3, the swing frame 5 in this portion has a bottom plate 6b and an upper plate 6c, and an opening 6 is provided in a part of the upper plate 6c. The battery 7 is placed and fixed on a floor plate 6b, and the opening 6 is covered with a battery lid 6a so as to be openable and closable. Battery cover 6a is upper plate 6
c, and is supported by support plates 6d, 6d welded to the lower surfaces of the front and rear two sides of the upper plate 6c. Therefore, the upper surface of the battery cover 6a forms the same plane as the upper surface of the upper plate 6c. Note that a floor mat 9 is laid so as to cover the upper surfaces of the upper plate 6c and the battery lid 6a.

As shown in FIGS. 3 and 4, the battery cover 6a
A strip-shaped engaging plate 6e is welded to the lower surface of the device, and a footrest plate 6f is welded to the upper surface. Therefore, in order to close the opening 6 with the battery lid 6a, the footrest plate 6f is grasped by hand, the battery lid 6a is lifted, and the engaging plate
e is inserted into the lower surface of the upper plate 6c, and the battery lid 6a is placed on the support plate 6d. Thereafter, the battery lid 6a closes the opening 6 by its own weight, but the engaging plate 6e is locked to the lower surface of the upper plate 6c and the floor mat 9 is used to prevent the battery lid 6a from coming off due to vibration during operation. It is held down and floating is prevented.

Further, the other end of the battery cover 6a has the left foot on the foot rest 6f during the operation of the work machine.
In particular, lifting prevention is not necessary. 6g is a thin rubber plate for preventing slippage provided on the footrest plate 6f so that the foot does not slip. When checking the battery 7,
The worker stands up from the seat 5a, lifts the battery lid 6a through the reverse process to open the opening 6, and can inspect the battery 7 inside. Therefore, since the battery 7 can be accessed without any special tool for inspection, the operation can be easily performed.

FIG. 6 shows the mounting means of the battery 7. The battery 7 is mounted on a receiving frame 7b made of a steel plate bent in an upward U-shape. A handle 7a is attached. That is, the handle 7a is composed of a connecting bar 7c and pressers 7d, 7d of which the cross section welded to both ends is inverted L-shape.
b Presser foot 7d, bolt 7e screwed to the upper end on both sides,
7d is pressed downward, so that the battery 7
b, and the handle 7a is attached to the upper part of the receiving frame 7b. Then, the battery 7 is detached from the opening 6 provided in the swing frame 5 by holding the connecting bar 7c.
The battery 7 can be fixed to the swing frame 5 by an appropriate means such as bolting the receiving frame 7b to the side plate of the swing frame 5.

FIG. 10 shows a modification of the handle 7a.
The connecting bar 7c is arranged so as to be entirely close to the battery 7, and is located between the liquid injection caps 7f, 7f of the battery. Therefore, even when the tightening by the bolt 7e is somewhat weak, the battery 7 does not move. Then, in order to hold the connecting bar 7c by hand, a part thereof is bent upward in a crank shape to facilitate holding.
