Abstract

(57) [Summary] [Purpose] The engine room provided below the cab can be fully opened to improve maintainability. An engine compartment 5 in which an engine 6 is housed is provided below a driver's cab 4 having a rear door 4b which can be freely opened and closed on the rear surface. With the engine hood body 7 attached to the engine hood, the rear portion of the engine hood body 7 is projected rearward from the rear surface of the cab 4, and the rear door 4b of the cab 4 is opened, so that the hinge 8 is centered. The engine hood body 7 can be fully opened to the front, and the engine 6 can be serviced or repaired with the engine room 5 fully opened, which greatly improves maintainability.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an engine hood of a construction machine having an engine room below a driver's cab.

[0002]

[Prior art]

 As shown in FIG. 1, there is a conventional construction machine in which an engine room c covered with an engine hood b is provided below a cab a, and an engine d for power is housed in the engine room c. In the construction machine as described above, when the engine d is to be serviced or repaired, first the rear door e of the operating room a is opened, and then the engine hood b is opened in the operator's cab a to perform the work. However, there is a problem in that workability is poor because the work is performed in a narrow cab a.

In order to improve such a problem, for example, as in the construction machine described in Japanese Utility Model Laid-Open No. 12981/1990, the engine cover has a split structure and the rear portion of the engine cover is opened and closed to repair or repair the engine. There are also proposals for enabling the above.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional construction machine, since the engine cover is not fully opened, it is difficult to maintain the front side of the engine. The present invention has been made in order to solve such a problem, and an object thereof is to provide an engine hood for a construction machine with improved maintainability.

[0005]

[Means and Actions for Solving the Problems]

 In order to achieve the above-mentioned object, this invention provides an engine room accommodating an engine under a driving room having a rear door that can be opened and closed at the rear surface. A hinged engine hood body is provided on the engine hood body, and the rear portion of the engine hood body is projected rearward from the rear surface of the operator's cab, and the rear door of the operator's cab is opened so that the engine hood main body is centered around the hinge. It is designed so that it can be fully opened forward.

With the above configuration, the engine can be inspected and serviced or repaired with the engine room fully opened, so the serviceability is greatly improved.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS. 2 is an overall side view of the construction machine, FIG. 3 is an enlarged side view near the cab, FIG. 4 is a rear view of the same, and FIG. In these figures, reference numeral 1 denotes a vehicle body of a construction machine, which is free-running by wheels 2, a working machine 3 is provided in the front portion of the vehicle body 1, and a driver's cab 4 is provided in the upper portion. The cab 4 is provided with openable and closable doors 4a and 4b on both sides and the rear surface thereof, and an engine cab 5 is provided below the cab 4, and the engine cab 5 for power is provided in the engine cab 5. The engine 6 is housed.

The upper part of the engine compartment 5 is covered with an engine hood body 7. A front portion of the engine hood body 7 is hinged to the vehicle body 1 by a hinge 8 so that a rear portion of the engine hood body 7 can be opened upward with the hinge 8 as a center. It is projected rearward from the rear surface.

On the other hand, the rear door 4b provided on the rear surface of the operator's cab 4 has an upper part hinged to the operator's cab 4 by a hinge 9, and the lower part can be opened upward with the hinge 9 as a center. At the same time, when the rear door 4b is closed, the lower portion of the rear door 4b comes into liquid-tight contact with the upper surface of the engine hood body 7 so that rainwater and the like do not enter the operator's cab 4.

To explain the operation, the engine hood body 7 is closed during normal operation to prevent noise and hot air from entering the operator's cab 4. For repair, first open the rear door 4b upward as shown in FIG. 5, and then open the engine hood body 7 forward. As a result, the inside of the engine room 5 is fully opened, so that the engine 6 can be easily inspected, maintained and repaired. Further, since the work can be performed from the outside of the operator's cab 4, the workability is remarkably improved as compared with the case of working in the conventional operator's cab 4.

[0011]

[Effect of device]

 As described in detail above, this invention projects the rear part of the engine hood main body, which is provided so as to cover the engine room under the driver's cab, rearward from the rear surface of the driver's cab and hinges the front part of the engine hood main body. Since the engine hood body can be fully opened forward around the hinge by hingedly attaching to the vehicle body and opening the rear door of the cab, the engine can be inspected and repaired from the outside of the cab as well. It will be possible to do so, and maintainability will be greatly improved compared to conventional construction machinery.
