Description

Tracked vehicle for laying soil material {Caterpillar For Spreading Earth Materials}

The present invention relates to a track vehicle for laying sedimentary materials, and in particular, it is configured to freely move the super soft ground.

In order to use the land more efficiently and to secure industrial sites, the use of dredged or reclaimed ground by marine clay becomes more important. In particular, in developing the site, soft ground treatment is very important, and the treatment period of soft ground is recognized as a very important factor in the construction of the complex. In particular, the development of surface treatment for securing equipment operability in ultra-soft ground has become a big concern in the field of ground research.

In the case of dumping the soft viscous soil piled on the seabed with a pump dredger and dumping it in the landfill, the initial state of the landfill is a slurry state and forms a super soft ground with high water content. You can't expect it at all.

That is, the soft ground, especially the ultra soft ground in the slurry state is difficult to enter the equipment for the ground improvement work, so it is difficult to improve the soft ground, technically difficult, and to secure the running of the equipment Surface treatment must be preceded.

As such, the surface treatment step of reinforcing the surface of the soft ground so that equipment can enter and run is the first step of the ground improvement work, which is an urgent task of related industries.

Conventionally, the surface treatment method is a natural drying method that improves the surface layer by self-weight consolidation and natural drying by leaving the ground after dredging for several years, and solidifying to solidify the surface layer by mixing and stirring cement-based chemical liquid with the surface of the surface layer. There is a treatment method, there is a horizontal vacuum drainage method to increase the bearing capacity by promoting the consolidation by dissipation of excess pore water pressure generated in the ground by burying the drain material horizontally at regular intervals in the super soft ground surface layer and applying a vacuum pressure.

However, even if the construction proceeds with the surface treatment method described above, a small dump truck of 1 to 2.5 tons should enter the surface treatment place. In the case of ultra-soft ground, it is difficult to enter the small dump truck, Many accidents, such as fall and fall. In addition, there is a problem that the construction progress is quite difficult due to frequent destruction and collapse of the ground.

Recently, the surface treatment method of super soft ground has been widely used surface coating method of laying sand, aggregate, and other soil material on super soft ground using bulldozer laying equipment.

However, since this method also requires equipment such as bulldozers and small dumps to travel on the super soft ground, there is a serious problem in the risk of destruction and collapse of the ground and conduction accident and safety of the vehicle at the super soft ground tip.

The present invention has been invented to solve the problems of the prior art as described above, the first place by filling or transporting the place where it is almost impossible to enter the equipment for the ground improvement work in reclaimed land or landfill area consisting of ultra-soft ground In improving the weak ground, it is possible to prevent plastic destruction of the surface layer on the super soft ground, to prevent the fall of the transport vehicle in advance, and to provide a track vehicle for laying the landfill material configured to freely rotate the load box to drop the landfill at the correct position. Its purpose is to.

Technical features include a loading box for adjusting the tilt by the stroke expansion and contraction of the system, and a cab located in the rotary tower.

Further, according to a preferred embodiment of the present invention, a slewing bearing is mounted between the vehicle body and the rotary tower so that the rotary tower rotates relative to the vehicle body.

In addition, according to a preferred embodiment of the present invention, the rotary tower includes a rotary table mounted to the swing bearing, the cab is located in front of the rotary table, the stacker is located behind the cab, the hydraulic A system is mounted on the upper surface of the turntable to tilt or lift the stacker horizontally as the stroke stretches.

Further, according to a preferred embodiment of the present invention, the rear end of the rotary table and the rear end of the loading bin are hinged so that the loading bin is inclined by the stroke extension of the hydraulic system.

As described above, the track vehicle for laying sedimentary materials of the present invention freely enters and runs the reclaimed land or landfill, which is an ultra soft ground, and is configured to drop the loaded sedimentary materials at the correct position to shorten the construction period of the surface treatment step. As a result, the construction period of the ground improvement work can be shortened.

In addition, the track vehicle for laying sedimentary material according to the present invention can prevent the occurrence of safety accidents because the accident of overturning and falling does not occur even when entering and driving into the ultra soft ground.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of a track vehicle for laying soil material according to the present invention will be described in detail.

As shown in FIG. 1, the track vehicle 100 for laying the ground material is largely driven by the track wheels 111 and rotates and rotates on a top surface of the vehicle body 110. 120, a loading box 130 positioned on an upper surface of the rotary tower 120 to adjust the inclination by the hydraulic system 123, and a cab 140 positioned in front of the rotary tower 120. .

Hereinafter, a detailed description will be given of the track vehicle for laying landfill material configured as described above.

As shown in FIGS. 2 and 3, the vehicle body 110 travels and turns by a pair of parallel track wheels 111. The driver controls the progress, direction, braking, and inclination of the stacker 130 in the cab 140.

In the center of the upper surface of the vehicle body 110, a slewing bearing 150 as shown in FIG. 4 is mounted. The swing bearing 150 is a bearing already commercialized in excavators and tanks.

As shown in FIG. 5, the pivot bearing 150 includes an inner race 151 mounted on the rotary tower 120, an outer race 153 mounted on a vehicle body, and an inner race 151 and an outer race 153. It includes a cross roller 155 mounted on the opposite side of the), the rotary tower 120 is free to rotate relative to the vehicle body 110 by the pivot bearing 150, the inner race 151 ) Is connected to a motor not shown in the drawings, the rotary tower 120 is rotated by the driving of the motor, and the rotation of the rotary tower 120 is stopped by the stop of the motor.

Meanwhile, the rotary tower 120 includes a rotary table 125 on which the inner race 151 of the swing bearing 150 is mounted, an cab 140 located in front of the rotary table 125, and the cab 140. It includes a hydraulic system 123 for tilting up or down the loading box 130 located in the rear). The hydraulic system 123 is a device for controlling the flow of fluid to reciprocate the piston 123P of the hydraulic system 123 to expand and contract the stroke, the end of the piston (123P) of the hydraulic system 123 is the bottom of the loading box The cylinder 123S, which is hinged to and supports the piston, is hinged to the upper surface of the rotary table 125, and the cylinder of the hydraulic system 123 is inclined so as to lift the stack 130.

The loading box 130 seated on the upper surface of the rotary table 125 has a hinge 131 coupled to the rear end of the rotary table 125, and the piston end of the hydraulic system 123 is located at the center of the bottom surface of the loading box 130. The hinges are combined.

When the landfill material is installed in reclaimed land and landfill using the tracked vehicle 100 for laying landfill configured as described above, the landfill material is loaded in the loading box 130. Then, the driver enters the cab 140 to drive the vehicle body to enter the reclaimed land and landfill.

At this time, the track wheel 111 of the vehicle body 110 has a large surface area, thereby spreading the load of the tracked vehicle 100 for laying soil material widely, so that the track wheel does not fall into the reclaimed land or landfill. As described above, when the tracked vehicle 100 having the tracked wheels 111 is compared with a conventional 1 to 2.5 ton vehicle, the tracked wheels 111 are widely dispersed in the weight of the vehicle, thereby allowing the super soft support base in the slurry state. Less missing However, in the case of 1 to 2.5 ton vehicles according to the conventional method, the load is concentrated on the tire, that is, the round wheels, and the wheels fall into the ultra soft ground, making it impossible to proceed.

On the other hand, the track wheel 111 is because the entire length of the track wheel is nine wheels, even if a part of the track contact with a solid ground can be pulled out of the ultra soft ground in the slurry state.
