Description

Cabin window guard device for construction equipment {a cabin window guard apparatus for a construction heavy equipment}

The present invention relates to a cabin window guard device for heavy construction equipment, and more particularly to a window guard (Window Guard) to be easily mounted or detached in front of the windshield (Cabin).

In general, when drilling through a breaker (breaker) of heavy equipment can be stone or other crushed material can be scattered, it is likely that the windshield of the cabin is damaged by such scattering material.

Therefore, when drilling the heavy construction equipment, there are many cases in which a window guard made of a support frame and a protective wire mesh is installed in front of the windshield of the cabin.

1 is a perspective view of a cabin window guard device of a conventional heavy construction equipment.

Conventionally, the cabin window guard device of the heavy construction equipment has mounting pieces 223a and 223b on both sides of each of the support frames 221a and 221b of the upper window guard 220a and the lower window guard 220b, as shown in FIG. The mounting pieces 223a and 223b are mainly used to be fastened to the front surface of the cabin 200 through the fastening bolts 224a and 224b.

However, since each window guard 220a of the protective wire mesh 222a, 222b is installed in the support frame (221a, 221b) is a heavy body, in the cabin window guard device of the conventional heavy construction equipment, each worker Lift the guards 220a and 220b and position them in front of the windshield 210 of the cabin 200, and fasten a plurality of fastening bolts 224a and 224b with the fastening tool to secure each window guard 220a and 220b to the cabin. There was a problem that the work to be mounted on the 200 is very cumbersome.

In addition, when the window guards 220a and 220b are mounted on the windshield 210 of the cabin 200, the worker's view is deteriorated. It is better to remove each of the mounted window guards 220a and 220b. However, in the conventional cabin window guard device, a plurality of fastening bolts 224a are supported by the window guards 220a and 220b of the heavy body by hand. Unwinding (224b) and separating each window guard (220a) (220b) from the cabin 200 is also difficult, there is a problem that also has to be troublesome to store each separated window guard (220a, 220b) in a safe place. .

In addition, in the cabin window guard device of the conventional heavy construction equipment, the mounting pieces 223a and 223b are damaged or the fastening bolts 224a and 224b during the mounting and detaching of the window guards 220a and 220b. Damage to the nut occurs, so that each window guard (220a, 220b) itself can not be used, there was a problem that occurs frequently.

The present invention has been made in view of the conventional situation as described above, the object is to make it easier to install or detach the window guard in front of the windshield of the cabin, as well as the window guard separated from the windshield front of the cabin It is to provide a cabin window guard device of heavy equipment for easy storage.

Cabin window guard device of the heavy construction equipment of the present invention for achieving the above object is detachably installed on the front of the cabin, the upper window guard can be rotated in the vertical direction through the rotation support link on the top of the fixed frame. To keep the upper window guard in the cabin ceiling; The hinge bushing is installed at one lower side of the fixed frame, and the hinge connecting shaft corresponding to the hinge bushing is provided at one side of the lower window guard so that the hinge connecting shaft of the lower window guard can be inserted into or separated from the hinge bushing of the fixed frame. The window guard can be mounted on or detached from a fixed frame.

That is, the present invention in the construction of the cabin window guard device of the heavy construction equipment in which the upper window guard and the lower window is detachably installed in front of the windshield of the cabin, the removable frame is detachably installed around the windshield of the cabin The upper window guard is rotatably installed in the vertical direction through the rotation support link on the fixing frame so that the upper window guard can be stored on the ceiling of the cabin.

In addition, the cabin window guard device of the heavy equipment of the present invention is installed by the hinge bushing on the lower side of the fixed frame, the hinge connecting shaft corresponding to the hinge bushing on one side of the lower window guard to fix the hinge connection shaft of the lower window guard By simply inserting or removing the hinge bushing of the frame, the lower window guard can be easily mounted or removed from the fixed frame.

Cabin window guard device of the heavy construction equipment of the present invention is a fixed link protruding on both sides of the fixed frame, one end of each rotary support link hinged to each fixed link, the other end of each rotary support link upper window It may be configured in the form hinged to both lower sides of the support frame of the guard.

In addition, a first fixing clamp is installed at both lower ends of the upper window guard, which is fixed to the fixing frame when the upper window guard is positioned in front of the cabin windshield, and the upper window guard is stored on the ceiling of the cabin at both sides of the upper window guard. When the second fixing clamp is fastened to the fixing brackets provided on both sides of the upper rear of the cabin can be configured.

Meanwhile, in the cabin window guard device of the heavy construction equipment of the present invention, a pair of hinge bushings are installed at one lower side of the fixed frame, and a pair of hinge connecting shafts corresponding to the hinge bushings is installed at one side of the lower window guard. Each hinge connecting shaft of the lower window guard may be inserted into and connected to the hinge bushing.

And when the lower window guard is located in front of the cabin windshield on the other side of the lower window guard may be configured in the form of a third fixed clamp that is fastened to the fixed frame, the front of both sides of the fixed frame and the lower side of the front both sides It may be configured in the form of a buffer stopper is installed in contact with the back of the support frame of the upper window guard and the back of the support frame of the lower window guard to reduce the vibration.

According to the cabin window guard device of the heavy equipment of the present invention, it is possible to more easily install the upper window guard and the lower window guard in front of the cabin windshield, as well as easily remove the upper window guard and the lower window guard from the front of the cabin windshield.
