Description

[Detailed description of the invention] [Industrial field of application] The present invention provides an operating cabin on a swivel platform over almost the entire width of the operating cabin, and a hydraulic oil tank on the side of the operating cabin. This invention relates to a shovel work vehicle in which a battery and a battery are arranged in the front and rear.

[Conventional technology]

Conventionally, in the above-mentioned excavator work vehicle, the battery and the hydraulic oil tank are surrounded by a cover and a side wall of the operating cabin, and the battery is configured to be attached and removed within the operating cabin.

[Problem that the invention attempts to solve]

However, since there is no place for the heat to escape from the hydraulic oil in the tank, the heat can be released into the operating cabin through the cover and become trapped inside the operating cabin. This has the disadvantage that the battery cannot be smoothly attached or detached.

The purpose of this invention is to prevent the inside of the operating cabin from becoming hot due to the heat of the hydraulic oil in the tank, to facilitate the installation and removal of the battery, and to create a structure that is easy to manufacture and process to prevent damage to the battery. The key point is to gain from this.

[Means for solving problems]

A characteristic configuration of the excavator work vehicle of the present invention is that a part of the lateral wall of the driving cabin is recessed, and the hydraulic oil tank and the battery are housed in the recess, and the battery is housed in a battery case. Further, an opening for exposing the hydraulic oil tank is provided on the outer side of the hydraulic oil tank, and an opening/closing lid for putting in and taking out the battery is provided on the outer side of the battery case. Its functions and effects are as follows.

[Effect]

In other words, the heat of the hydraulic oil is radiated outward from the hydraulic oil tank through the opening on the outside of the recess, and the cooling efficiency is high, so the inside of the driving cabin does not get hot, and the battery is placed on the side of the driving cabin. It can be easily taken out through the doorway with an opening/closing lid. Since the battery case blocks heat transfer due to heat radiation from the hydraulic oil tank, it suppresses temperature rise and evaporation of the battery fluid.

[Effect of idea]

Therefore, the living environment for the operator can be improved, deterioration of the hydraulic oil can be effectively suppressed, and repair and inspection of the battery can be performed very easily. Since the battery is housed in a battery case and placed in a recessed part, the battery case blocks heat transfer due to heat radiation from the hydraulic oil tank, causing a voltage drop due to a rise in battery fluid temperature and an early rise in battery fluid. Evaporation can be suppressed.

Moreover, in order to block heat transfer due to heat radiation from the hydraulic oil tank, it is internally installed in the case, so for example, when a partition wall is installed between the tank and battery to block heat transfer. In comparison, it is easier to form an airtight chamber.

In other words, if a partition wall is provided inside the recess to separate the hydraulic oil tank and the battery, it will be difficult to form an airtight chamber due to irregularities in the manufacturing process of the recess, but if the partition wall is installed inside the case. If,
Regardless of any errors in the manufacturing process of the recessed part, an airtight chamber can be formed externally with high precision, and it becomes easy to form an airtight chamber for suppressing evaporation of battery fluid.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 4, a swivel base 2 is attached to a machine base equipped with a crawler traveling device 1 through a rotary joint (not shown) so that it can be driven and rotated freely around the vertical axis P. , on the swivel base 2, an operating cabin 6 in which a fuel tank 3, a driver's seat 4, each operating lever 5, etc. are arranged is installed over almost the entire width of the swivel base 2, and a part of the lateral side wall 6A of the operating cabin 6 is The hydraulic oil tank 7 and the battery 13 are arranged in the recessed part A, and the engine E
A driving unit 8 with a hydraulic pump 14 inside and covered by a bonnet is disposed at the rear, and a backhoe device 9 that can freely swing up and down and bend/stretch is attached to the base bracket 10 at the front end of the swivel base 2. Vertical axis center by swing cylinder 11 through
The dozer device 12 is connected around P ₁ so that it can be swung left and right, and a dozer device 12 that can be driven up and down is attached to the front end of the machine base, forming an earthmoving mechanism work vehicle that mainly performs ground excavation and earth removal work. .

The battery 13 is housed in a battery case 16 having a swingable open/close lid 15 on one side and installed in front of the hydraulic oil tank 7, and both the battery case 16 and the hydraulic oil tank 7
The inside of the driving cabin 6 is covered with a recessed wall 17.

In the side wall 6A of the operating cabin 6 on the side where the hydraulic oil tank 7 and battery case 16 are arranged, there is an opening 18 through which the hydraulic oil tank 7 is exposed to the outside.
The opening/closing lid 15 of the battery case 16 is integrally cut out to form an opening 19 that is exposed to the outside.
are arranged so that they are all approximately on the same plane.

The shovel work vehicle according to the present invention may be applied not only to one equipped with a backhoe device but also to various types equipped with various shovel devices such as a face shovel device.
