Abstract

PURPOSE: A wheel excavator with a foldable bucket rest is provided to facilitate work in small space by reducing turning radius of equipment because a bucket rest is installed to be rotated with respect to a lower frame depending on workplace environment. CONSTITUTION: A wheel excavator with a foldable bucket rest includes a lower traveling body(1), a lower frame(2), an upper revolving body(5), a work equipment(12), a bracket for a bucket rest, a bucket rest(13), and a fixing pin for the bucket rest. The lower frame is loaded on the lower traveling body. The upper revolving body is turnably mounted on the lower frame and has a cabin cap(3) and an engine room(4). The work equipment is turnably fixed in the upper revolving body. The work equipment includes a boom(9), an arm(10), and a bucket(11) which are respectively driven by hydraulic cylinders(6,7,8). The bracket for the bucket rest has first and second coupling holes in the upper and lower parts. The fixing pin for the bucket rest is inserted into a second coupling hole and a second through-hole in driving to be fixed in the bracket in a state where the bucket rest is unfolded with respect to the lower frame. In case of operation, the fixing pin is inserted into a first coupling hole and a first through-hole in a state where the bucket rest is folded with respect to the lower frame.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings, which is intended to explain in detail enough to enable those skilled in the art to easily practice the present invention. It is not intended that the technical spirit and scope of the invention be limited.

Wheel type excavator equipped with a folding bucket rest according to an embodiment of the present invention shown in Figures 2 to 4,

The lower traveling body 1,

A lower frame 2 mounted on the lower traveling body 1,

An upper swinging body (5) rotatably mounted to the lower frame (2), to which the cab cap (3) and the engine compartment (4) are mounted;

Work device 12 fixedly rotatable to upper pivot 5 and including boom 9, arm 10, bucket 11 driven by respective hydraulic cylinders 6, 7, 8. Wow,

Bucket rest brackets 16 and 17 fixed to the front left and right sides of the lower frame 2 and having first and second coupling holes 14 and 15 formed on the upper and lower sides thereof. ) Is formed in pairs on the left and right sides respectively),

It is rotatably fixed by fixing pins 20 and 21 fixed to the bucket rest brackets 16 and 17, and corresponding to the first and second coupling holes 14 and 15, respectively. Bucket rest 13 is formed 40,

When driving, it fits into the second coupling hole 15 and the second through hole 40 and is fixed to the bucket rest brackets 16 and 17 with the bucket rest 13 extended to the lower frame 2. Fixing for the bucket rest which is inserted into the first coupling hole 14 and the first through hole 30 and fixed to the bucket rest brackets 16 and 17 in a state where the bucket rest 13 is folded about the lower frame 2. Pins 18 and 19.

At this time, the configuration including the lower traveling body 1, the lower frame 2, the upper swinging structure 5, the work device 12, and the like described above is substantially the same as the configuration of the prior art shown in FIG. Since the configuration and operation thereof are the same, detailed descriptions thereof will be omitted, and reference numerals of duplicate parts will be denoted the same.

Hereinafter, a use example of a wheel type excavator equipped with a folding bucket rest according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 and 3, the bucket rest 13 by fixing pins 20 and 21 fixed to the bucket rest brackets 16 and 17 formed at the front left and right sides of the lower frame 2 as described above. Is rotatably fixed. In addition, a bucket rest fixing pin 18 is inserted into the second coupling hole 15 formed below the bracket rest brackets 16 and 17 and passes through the second through hole 40 formed in the bucket rest 13. Bucket rest 13 is fixed by 19.

For this reason, the bucket rest 13 described above is fixed to the bucket rest brackets 16 and 17 while maintaining the unfolded state with respect to the lower frame 2.

Therefore, when the equipment is running, the bucket 11 is placed on the bucket rest 13 which maintains the unfolded state with respect to the lower frame 2 (the bucket rest 13 is extended as shown by a virtual line in FIG. 2). You can drive with.

2 and 4, the bucket rest 13 by fixing pins 20 and 21 fixed to the bucket rest brackets 16 and 17 respectively formed on the front left and right sides of the lower frame 2 as described above. Is rotatably fixed. In addition, a bucket rest fixing pin 18 fitted into the first coupling hole 14 formed on the upper side of the bracket rest brackets 16 and 17 and passing through the first through hole 30 formed in the bucket rest 13. Bucket rest 13 is fixed by 19.

For this reason, the bucket rest 13 described above is fixed to the bucket rest brackets 16 and 17 while being in a folded state with respect to the lower frame 2.

Therefore, when the equipment is in operation, the bucket rest 13 can be folded about the lower frame 2 (as shown by the solid line in FIG. 2, the bucket rest 13 is raised toward the lower frame 2). Because of the folding, it does not protrude from the wheels). This makes it possible to perform smooth work even in narrow spaces such as alleys.

According to the wheel type excavator equipped with the folding bucket rest according to the embodiment of the present invention as described above, according to the environment around the workplace, the bucket rest is rotatably mounted to the lower frame of the wheel type excavator, the bucket rest during driving The bucket can be placed in the unfolded state, and during operation, the bucket rest can be folded to reduce the turning radius so that it can work smoothly in a narrow space.
