Problems solved by technology

[0008] The structure of the conventional construction machine described above has the following problem: it is difficult to install the fire wall 17 made of a single plate in the narrow pump-side space S in the engine room 7
Especially for the width dimension of the pump side space S like a small excavator ( Figure 5 For small construction machines in which the pump side panel, that is, the distance W) between the left side panel 10 and the end of the engine 8 is small, the above-mentioned problem is significant and the assembly is poor.
In addition, the overall area of ​​the firewall 17 is large and the cost is relatively high

Embodiment Construction

[0019] according to Figure 1 to Figure 3 Embodiments of the present invention will be described.

[0020] This implementation is based on the Figure 4 Excavators identical to those shown are applicable. That is, the excavator according to this embodiment includes: a crawler-type undercarriage; an upper revolving body mounted on the crawler-type undercarriage; and an operation attachment attached to the upper revolving body. , the upper slewing body has: an upper frame as a base, which is arranged on the front part of the upper frame and on one of the left and right sides (usually the left side. Hereinafter, it will be described in this case) The driver's cab, and the counterweight arranged at the rear end of the upper frame. On the upper frame, at the position behind the cab and in front of the counterweight, there is formed a figure 1 and figure 2 Shown is an engine room 27 in which an engine 28 as a power source is installed.

[0021] The engine compartment 27 is fo...

Abstract

A construction machine equipped with: multiple guard members surrounding an engine room; an engine housed in the engine room; a hydraulic pump provided on one side of the engine; and a fireproof plate that forms a fireproof wall for the purpose of shielding this hydraulic pump from the high-temperature parts of the engine. The guard members include a pump-side panel arranged facing the hydraulic pump. The fireproof plate is arranged in a pump-side space formed between the pump-side panel and the engine so as to divide this pump-side space into an upper and a lower section, and this fireproof plate has a front end part which approaches the inner surface of the middle part of the pump-side panel in the height direction. This fireproof plate and the pump-side panel form the fireproof wall.

Description

technical field [0001] The present invention relates to a construction machine such as an excavator. The construction machine includes a hydraulic pump, an engine, and a fire wall for preventing oil scattered from the hydraulic pump from falling to high-temperature parts such as a muffler or an exhaust pipe of the engine. Background technique [0002] by Figure 4 The excavator shown is taken as an example to describe the background art of the present invention. [0003] This excavator includes: a crawler-type lower traveling body 1 ; an upper revolving body 2 mounted on the crawler-type lower traveling body 1 ; The upper slewing body 2 has an upper frame 4 as a base, a driver's cab 5 installed on one of the left and right sides (usually the left side, hereinafter, described in this case) at the front of the upper frame 4 , and an upper frame 4 . The counterweight 6 of frame 4 rear end. An engine room 7 is formed at the rear side of the cab 5 and at the front side of the c...
