The present invention relates to a safety net for excavators, and more particularly, is installed in the front window front of the cab, as the movable motor is installed to be moved upwards along the ceiling of the cab along the moving rail, the glass window of the cab during the crushing operation By moving to the front part to protect the cab from splinters splashing in all directions, and during other work without splinters, it moves to the upper part of the cab ceiling so as not to obstruct the driver's vision. It relates to a safety net for excavators that can be increased.

In general, an excavator is a construction machine capable of building foundation works, housing site construction work, cargo loading, earth and sand loading, bridge hole digging, road construction, water and sewage construction, etc., by attaching a breaker or bucket to an arm fastened to a boom use.

In other words, when breaking a hard part such as rock or brick, the work is performed by fastening the breaker to the arm, and the work is by fastening the bucket to the arm when the crushed material by the breaker is spread or the dust is spread.

However, when the breaker is fastened to the arm of the excavator to break a hard part such as a rock or a brick, the crushed and broken pieces by the breaker will fly out in an unpredictable direction.

At this time, if the crushed object is blown to and fro and hit the front window of the excavator's cab, the windshield is not only damaged by the impact, but if the crushed object is large, the degree of damage is severe and the driver may be injured. there was.

In order to solve this problem, a safety net made of steel was installed at the front of the windshield so that the shreds do not hit the windshield.

Accordingly, even when the crushed material flies to the front windshield side of the cab, the safety net blocks the crushed material to prevent damage to the windshield and also to keep the driver's safety.

However, if the safety net is installed on the front surface of the front window of the cab to block the crushed object as described above, the purpose of blocking the crushed object when the work to break the hard part such as rock or brick by fastening the breaker to the arm Achieve this, but when the work to spread the crushed matter or to spread the dirt by fastening the bucket to the arm, there was a problem that obstructs the work rather than obstruct the driver's view.

As a result, most drivers were reluctant to install safety nets, so they were exposed to safety accidents caused by debris by working without them.

The present invention has been invented to solve the above problems, to allow the driver to work safely from debris when working with a breaker and to smoothly work without obscuring the driver's field of view when working with a bucket. In order to be able to, to configure a safety net installed to protect the cab of the excavator from the crushed object, a pair of rails provided at fixed intervals by a fixed frame on both sides of the front and top of the cab; A mesh body installed between the rails to block the front part of the cab, the chains having one end of the rollers moving along the rails connected to both ends thereof to be movable to an upper surface of the cab; A driving motor installed at an upper surface of the cab to rotate a drive shaft arranged at both ends of the sprocket engaged with the chain, thereby freely moving the mesh along the rail; Its purpose is to provide a safety net for excavators characterized in that it is configured.

The safety net for excavators of the present invention moves to the front part of the window of the cab during the crushing operation using a breaker to protect the cab from crushing objects splashing in all directions. By not moving to the driver's field of view so as not to obstruct, there is an effect that can increase the efficiency of the work with the safety of the operator at the same time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Excavator safety net 100 of the present invention, as shown in Figure 2 in the construction of the safety net installed in the front window (W) of the cab (D) of the excavator (E), the front part and the top surface of the cab (D) A pair of rails 2 installed at fixed intervals by fixed frames 1 on both sides of the unit; Installed between the rails 2 so as to block the front part of the cab D, the chains 4 installed at one end of the rollers 3 moving along the rails 2 are connected to both ends of the cab D, respectively. And the net body 5 is installed to be movable up to the upper surface portion; A drive motor for freely moving the mesh 5 along the rail 2 by rotating the drive shaft 7 installed at both ends of the sprocket 6 fitted to the chain 4 at the upper surface of the cab D. As (8); Characterized in that configured.

The network 5 is a plurality of horizontal ring rods 11 and the horizontal ring bar that is continuously installed on the connecting shaft (9) of the chain (4), respectively, the connecting groove 10 is formed at a predetermined interval as shown in FIG. It is composed of a plurality of vertical connectors 13 connected to the connecting groove 10 through the connecting ring 12 provided at both ends between the (11) to connect between the horizontal ring bar 11 at a predetermined interval.

At this time, the drive motor 8 should be composed of a drive motor 8 driven in both directions.

Although not shown, an operation switch for controlling the operation of the drive motor 8 may be installed in the cab D to allow the driver to conveniently control the operation of the drive motor 8.

In the drawing, reference numeral 14 denotes a drive chain connecting the driven gear 15 and the drive gear 16 of the drive motor 8 arranged on the drive shaft 7, and 17 is a support frame supporting the drive shaft 7.

The safety net for excavator 100 of the present invention configured as described above is fastened from the crushed matter in all directions when fastening the breaker B to the excavator E as shown in FIG. 1 to break a hard part such as rock or brick. It is a safety device installed to protect the cab (D).

In particular, the safety net for excavator 100 of the present invention is characterized in that the smooth work is progressed by placing the upper surface of the cab (D) so as not to disturb the driver's view when the work using the bucket, unlike the above operation to be.

This is a net body 5 which is movably installed from the front part of the cab D to the top part by the roller 3 on the pair of rails 2 which are installed at predetermined intervals on both sides of the front part and the upper part of the cab D, respectively. Is due to being installed to be automatically moved by the drive motor (8).

That is, since the mesh 5 can be located at the front side of the cab D along the rail 2 through the drive of the drive motor 8 and can be located at the top surface of the cab D. will be.

Therefore, when the breaker (B) is fastened to the excavator (E) to break a hard part such as rock or brick, the driving motor 8 is driven through the operation switch so that the mesh 5 is the front part of the cab D. That is, to be located on the windshield (W).
