Description

Water jetting device for wheel loader {APPARATUS FOR INJECTING WATER FOR WHEEL LOADER}

The present invention relates to a water spraying device for a wheel loader, and in particular, during a cleaning operation of pushing and removing sludge generated in the steelmaking and ironmaking process with a bucket, water from the water tank is sprayed to the front tire and its surroundings, so that the high-temperature sludge is removed from the bucket. It passes through both the left and right sides so as not to damage the front tire, and by arranging the water tank on the rear side of the wheel loader without the need for a separate counterweight, it is possible to maintain the balance of the load using the water tank. , relates to a water injection device for a wheel loader whose structure is improved so that it can combine a function as a water tank and a function as a counter weight.

In general, wheel loaders carry out excavation work for excavating soil, sand, etc., transport work for transporting excavated soil and soil, loading and unloading work for loading or unloading transported soil on a freight vehicle, road stopping work, snow removal work, and towing work. It is widely used to perform etc.

Such a wheel loader has a structure including a boom installed on the front side of the vehicle and operated by a boom cylinder, and a bucket rotatably fixed to the tip of the boom and operated by a bucket cylinder.

The bucket is located at the front of the vehicle body when the boom is lowered, and rises from the lower part to a relatively high position by the boom operated by the boom cylinder to conveniently load the work in powder form such as soil, sand, etc. make it possible

At this time, a fender for a mudguard is disposed above the tire of the wheel loader used in a rough area. The fender prevents work or muddy water from scattering on the wheel loader's equipment through the tire while the wheel loader is working.

A conventional wheel loader equipped with a fender fixing device is a fender for a wheel loader by forming a first fixing device and a second fixing device respectively on upper and lower portions of a fender formed in a large or small size corresponding to the capacity of a construction machine or the size of a tire. was fixed.

Fixing the fender for the wheel loader prevents safety accidents that may occur during driving and work of the construction machine because the fender for the wheel loader consisting of two bodies is separated while the construction machine is running or working, and interferes with the work of the wheel loader because it becomes

At this time, the first fixing device and the second fixing device are respectively formed on the upper or lower portion of the fender for the wheel loader to fix the fender. In addition, in the case of the second fixing device, a U-bolt was used to connect and fix the fender body.

However, when the U-bolt is damaged by vibration or load applied to the construction machine while driving or working, there is a problem in that a safety accident occurs.

In addition, in order to dismantle the fixing device of the fender for a wheel loader, the first fixing device of the upper part of the fender must be dismantled and the second fixing device of the lower part of the fender must be dismantled, so it is very cumbersome for the operator, and the working time is increased, so the working efficiency is reduced There is a problem being

In addition, there is a problem in that the manufacturing cost of the construction machine increases as the U-bolt is frequently damaged.

As the prior art related to the fender of the existing wheel loader, as disclosed in Korean Patent Publication No. 10-2010591 "Wheel loader with fender fixing device" (registration date: 2019.08.07), between the first frame and the second frame A wheel loader provided with a fender fixing device for fixing a wheel loader, the fixing device comprising: a case part, a first pressing part hinged so as to be rotatable, and a second pressing part extending from the case part; and a spring having one end coupled to one side of the case portion and the other end coupled to the second pressing portion to support the first pressing portion and the second pressing portion; Including, the first pressing part and the second pressing part are rotated sequentially in a direction in which the spring is tensioned by an external force to release the fixation between the first frame and the second frame.

As another prior art related to the existing wheel loader, as disclosed in Korean Patent Application Laid-Open No. 10-2020-105024 "Method and system for controlling a wheel loader" (published date: September 7, 2020), the wheel so that the bucket enters the load accelerating the loader to carry out excavation work; acquiring signals necessary to determine tire slip of the wheel loader during the excavation operation; determining whether the tire slip occurs by performing a pre-learned prediction algorithm on the signals; if the tire slip occurs, decelerate the wheel loader and raise the bucket until the tire slip is removed within a desired value; And when the tire slip is removed, the bucket is moved along a preset automatic excavation trajectory.

However, when used in a steel mill among the existing wheel loaders, foreign substances such as high-temperature sludge and sludge are generated in the steelmaking and ironmaking process, and while scraping is performed using a wheel loader equipped with a bucket, high-temperature foreign substances are released from the bucket. There is a fear that the front tire is mainly pushed out to the left and right and comes into contact with the front tire, and thus the front tire may be damaged.
