Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a driving cabin over almost the entire width of the swivel base, and in a plan view, on the side of the inside of the driving cabin,
This invention relates to a shovel work vehicle in which the operator's comfort is improved by locating a battery covered with a cover and widening the interior of the driving cabin.

[Conventional technology]

Conventionally, in the above-mentioned excavator work vehicle, in order to prevent hydrogen gas generated from the battery when charging the battery from being trapped inside the driving cabin, the battery 01 is housed as shown in FIG. Cover 02 that covers the operating cabin 0
A bolt 06 and a nut 0 are attached to the top surface of the cover 02 through a sealing material 05 to open and close the lid 04, which is fixed inside the cover 02 and is used to take the battery 01 in and take it out, and to replenish battery fluid and distilled water.
It was installed in 7.

[Problem that the invention attempts to solve]

However, in the operating cabin, the bolts 06 for attaching the opening/closing lid 04 protrude from the top surface of the cover 02, making it dangerous for the operator to easily get caught, and making it difficult to insert and remove the battery 01, making it inconvenient. It was hot.

The purpose of the present invention is to make it easy to take the battery in and take it out, and to prevent it from getting stuck due to the cover.

[Means for solving problems]

The excavator work vehicle of the present invention is characterized by a battery opening with an opening/closing lid formed on the side wall of the driving cabin, and a swinging canopy on the top surface of the cover that is almost flush with it when closed. established,
A cabin lining member covering the closed canopy and the upper surface is removably attached, and its functions and effects are as follows.

[Effect]

In other words, the battery can be easily taken in and out without any obstruction by the opening with the opening/closing lid formed in the side wall of the operating cabin, and the top surface of the cover has a doorway with a lid that can be opened and closed. There is a canopy that can be swung open and closed flush with each other, and the cabin lining that covers them is removably attached to the closed canopy and the top surface, so there is no problem with the cover and there is no battery leakage. Hydrogen gas generated from the engine does not get trapped inside the operating cabin.

(Effects of the invention) Therefore, maintenance can be made easier through simple modifications, and moreover, the operator can now move around easily and with peace of mind without worrying about the cover.

Furthermore, when manufacturing an excavator without a driving cabin due to a user's request, for example, the lining member can be simply peeled off from the top surface of the cover and the canopy so that the canopy can be opened and closed. As a result, it became possible to easily replenish the battery inside the cover with battery fluid or distilled water without modifying the cover, which ultimately made it possible to use excavators with and without a driving cabin. This has made it possible to provide a cover that is easy to manage parts and is advantageous in terms of cost.

〔Example〕

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

As shown in Figures 2 and 4, the swivel base 2 is attached to the machine base equipped with the 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, various operating levers 5, etc. are arranged is provided over almost the entire width of the swivel base 2, and a hydraulic oil tank 7 and a battery 13 are installed in front of it.
are arranged side by side in the lateral side of the operating cabin 6 in plan view, and the driving unit 8, which has the engine E and the hydraulic pump 14 inside and is covered by the bonnet, is arranged in the rear part, and the swivel base 2 At the front end of
A backhoe device 9 capable of vertically swinging and bending/extending drive operation is connected via a base bracket 10 to a swing cylinder 11 so as to be able to swing left and right around the vertical axis _P1 , and a backhoe device 9 is attached to the front end of the machine base for lifting/lowering drive. It is equipped with an operable dozer device 12 and constitutes an earthmoving mechanism working vehicle that mainly performs ground excavation and earth removal work.

The battery 13 is housed in a battery case 16 which has an open/close lid 15 swingably attached to one side by a butterfly plate 20, and is installed in front of the hydraulic oil tank 7. 6 is covered with an interior cover 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.

To explain the battery case 16, as shown in FIGS. 1 and 3, the front and rear opposing side surfaces are formed into inclined surfaces 16A and 16A that are inclined rearward in accordance with the inclination of the arch 21 and the hydraulic oil tank 7, and the bottom plate It is extended and configured to double as a snap 16B, making it easy to enter and exit the operating cabin 6.The opening/closing lid 15 for loading and unloading the battery 13, which is attached to one side, is also attached to the front and rear inclined surfaces 16A, 16A.
It is formed into a substantially parallelogram shape with two opposing sides inclined, and the lid surface has a handle and a hole 22 for checking the liquid level of the battery 13 inside.
has been formed. A canopy 23 that is almost flush with the top surface 16C in the closed state is attached to the top surface 16C so that it can swing open and close using butterfly plates 24, 24, and further covers the canopy 23 and the top surface 16C when the canopy 23 is closed. The flexible cabin lining member 25 is
3 and 16C, and is sealed to prevent hydrogen gas generated from the battery 13 from leaking and filling the operating cabin 6.

[Another example]

The opening/closing lid 15 may be attached to the horizontal wall 6A to allow the battery 13 to be inserted or removed, and the opening 19
is simply called an entrance with an opening/closing lid. In addition to being housed in an independent box-shaped battery case 16, the battery 13 may be surrounded by an interior cover that covers the inside of the driving cabin 6, and these are simply referred to as covers.

The shovel work vehicle according to the present invention may be applied to various tines equipped with various types of shovel devices such as a face shovel device in addition to those equipped with a backhoe device.
