The present invention relates to a washing machine for washing tires of a large dump truck entering and exiting a construction site, and is configured by disassembling the washing machine in an assembly method to reduce the size and thereby reduce the manufacturing cost and to facilitate transportation. Is there.

In general, a washing machine is installed in the entrance of a construction site, sprays water on the tires of a car entering and leaving the construction site, washes the dirt on the tires, and prevents dirt from falling on the road when the road runs. It is to maintain a pleasant city life.

The washing machine used in the related art has a structure in which a washing device, an injection device, and a water tank are integrated to support a heavy load dump truck, and thus all materials are made of beams.

That is, the heavy load dump truck loaded with the cargo should go up to the upper part of the washing machine so that the washing machine should be operated. Since all the skeletons of the washing machine are made of high-strength beams, the manufacturing cost is high due to the expensive raw materials. There was a downside.

In addition, the conventional washing machine is made of a beam to withstand the load of the dump truck, so when the washing machine is completed, its own load is also high, so it is difficult to transport it in a factory that manufactures the washing machine.

In other words, since the washing machine itself was a heavy load, it was not possible to carry it with a general forklift truck.Therefore, there is a disadvantage that moving and carrying costs are expensive by using a crane. This was persecution.

On the other hand, in the construction site where the washing machine is installed, the ground was installed so that the tank could be fixed in order to install the heavy load washing machine, and then molded into cement before and after to secure a space for the washing machine.

As described above, after securing the space in which the washing machine is installed, the tank was formed by transporting the washing machine into the space formed on the ground and then fixed and used.

The truck was manufactured as described above using a crane to transport to the construction site, and then buried a tank in the access road of the construction site, and molded into cement before and after the truck to enter.

In other words, when water is supplied to the washing machine and the power is applied, and when the tire of the truck is located in the upper part of the support plate, the pump is operated by the operation of the sensor. Water was sprayed on to wash the tires.

However, since the conventional washing machine is a method in which water is injected by a compression pump, waste of extra energy is severe, and the nozzles are frequently clogged by recycling water containing soil, which significantly reduces the cleaning efficiency. There was this.

In order to solve the above problems, conventionally, it is conceived that water is sprayed and cleaned by installing an operating device using a roller in a washing machine so that the washing truck goes up to the washing machine and then rotates the tire to drive the roller.

However, the washing machine has to be inconvenient disadvantage because the driver of the truck shifts and stops the gear of the washing machine one by one, and thus the vehicle has to be washed as the vehicle progresses. This washing machine also solves the problem of bulky and heavy load. There was a problem that is difficult to transport and install.

Recently, in order to solve the above problems, a compression tank is installed at one side of the washing machine, and a water pipe is installed at the bottom of the compression tank to compress the air in the upper side while the water is different in the compression tank due to the tap water pressure. Then, a method of cleaning by spraying the compressed water by spraying the cleaning valve was devised.

However, the above method has a disadvantage in that it takes a long time to compress the water, which increases the waiting time of the truck. As a result, the truck driver rides on the truck while the tire is cleaned and waits for the fuel to be kept on. Wasted waste of.

In addition, the above method is a method of compressing water using only the pressure of the existing tap water, so it does not require energy separately, but the spraying time is shorter than the time of compressing the water. This was there.

And the above method has to use the clean tap water continuously, there is a disadvantage of severe waste of water, if you want to recycle the water in the tank had to install a pump to compress the water separately.

As described above, the three-wheeling method is a method of compressing and spraying water by using the pressure of tap water, so that the problem of having to install a pump separately could be solved, but it is difficult and difficult to carry because of bulky and high load. It did not solve the expensive problem.

The present invention has been invented to solve the problems described above, it is easy to assemble the use of the washing machine itself in the construction site to be easily assembled and used in the construction site is easy to transport, and the concrete floor molded on the ground Since the surface is used, it can be used regardless of the load of the truck.

That is, in the present invention, the washing machine itself may be assembled in a prefabricated manner, but when the concrete is formed in the access road of the construction place where the washing machine is installed, the water tank and the support base are formed to be formed to be disassembled for each part, and then the assembly may be directly assembled at the construction site. It would be.

In addition, the present invention is to maximize the efficiency of the washing by spraying the nozzle is installed on the lower end and both sides of the tire is sprayed water for cleaning.

And since the present invention is composed of a disassembly and assembly type, if any one part is broken, only the part needs to be repaired or replaced, thereby reducing the working time and reducing the cost.

It was done by installing

The water tank (3) is to install a sludge collection tank on the upper side of the inside of the tank to form a through-hole on the upper wall surface of the sludge collection tank to allow the water to flow to the bottom.

Referring to the operation of the present invention as described above is as follows.

The ground of the construction access road is dug to form a main body insertion part and a water tank insertion part, and a cement mortar is poured around the molded part.

In this state, the main body, the supporting plate and the water tank are transferred to the construction site, and then the main body 1 is placed on the main body insertion part molded of concrete on the ground, and then the water tank 3 is inserted into one side of the main body 1 to fix it. In this case, the guide plate 6 may be installed in the discharge hole 7 formed at one side of the main body 1 so that water and sludge may be inserted into the water tank 3, and the access path and the support plate may be installed to be horizontal. .

In the above state, the pump 4 and the air compressor 5 are installed at one side of the main body 1, and then the water is put into the water tank 3 and the power is applied, and the preparation is completed.

In this state, when the truck loaded with cargo enters the construction site and wants to leave the construction site, the tire enters the washing machine and the tire is placed on the support plates 20 and 20 'installed on the upper part of the main body 1. The operating lever 11 is installed at both ends of the perforated plate 8 to be operated.

That is, when the tire passes to the upper side of the operating lever 11, the operating lever 11 is rotated from the axis by the force pressed by the tire, thereby operating the chain 12 installed on the operating lever 11 The lever 11 is pulled as much as it rotates, and the chain pulls the chain gear 14 installed in the rotating nozzle 10 so that the chain gear 14 rotates.

At this time, the chain gear 14 installed on the rotating nozzle 10 is installed by a ratchet gear such as a gear installed on the bicycle so that the chain 12 is rotated by eating a pulling force in one direction so as to rotate the chain gear ( 11) is rotated, the nozzle 16 continues to rotate even when the chain is stopped by the force, the chain 12 is the length of the chain is pulled by the weightless weight 15 is installed at the end Will rise by.

When the operating lever 11 is operated as described above, the rotary nozzle 10 rotates and the pump 4 operates at the same time, so that the water in the water tank 3 is fixed with the fixed nozzle 9 through the pump. By spraying water through the rotary nozzle 10 is to be made.

That is, since the fixed nozzle 9 is installed at a portion corresponding to the inside of the tire, foreign matter on the tire is removed, and the nozzle 16 is disposed at the portion corresponding to the outside of the tire. The water is sprayed through the nozzle while the rotation is to be washed.

When the operation lever 11 is operated, the pump 4 is operated to supply the water in the water tank 3 through the pump 4 and the pipes, whereby water flows in the direction of the nozzle through each pipe. The rotary nozzle 10 is sprayed to the nozzle through the inside of the support pipe 13.

On the other hand, the end of the rotary nozzle 10 is formed to be inclined downward so that the water is inclined toward the central portion from the outside of the tire to wash the entire surface of the tire.

In the above state, when the washing by the pump 4 is finished, the pump is stopped, and water falls to the guide plate 6 installed inclined inside the main body 1 through the perforated plate 8 installed at both sides together with the soil. Then, the water and the soil is dropped into the water tank (3) installed on one side of the main body 1 by the guide plate (6).

When the cleaning is completed in this way, the pump 4 stops and the compressor 5 operates to supply air, and the air moves through the valve and flows through the water supply passage, and sprays the tire through each nozzle. By doing so, the water in the tire can be removed by air, and when the compressor is stopped by the timer, the washing is finished.

 When the cleaning is completed as described above, the vehicle is moved forward and the rear wheel tire is stopped again in the state positioned on the perforated plate (8), in this state is to be washed again by the above operating sequence.

Meanwhile in the present invention,

The water tank is inserted into the water tank insertion portion formed in the entrance of the construction site, and then the support plates 20 and 20 'are respectively installed on both sides of the water tank 3, and the pipes are connected between the support plates and the support plates.

When the vehicle enters in the above state and the front wheel stops at the upper portion of the support plates 20, 20 ', the washing is performed in the same order as described above, and the water flowing through the tire and the sludge support plate 20 20 'is inclined toward the water tank 3, so that water and sludge flow toward the water tank 3.

 Meanwhile, the second embodiment of the present invention will be described with reference to a case of using a washing method of storing and spraying water using water pressure.

When the valve is opened by connecting the water reservoir to the water reservoir, the water flows into the water reservoir 17 by the pressure of the tap water, and the air in the water reservoir 17 is compressed as the tap water flows in, thereby allowing the tap water to flow therein. do.

When the tap water is introduced and stored as described above, the valve of the water storage container 18 installed on one side is opened to allow the water in the water storage container 17 to flow into the water storage container 18 for injection, and the water As it enters the water reservoir 17 for injection, the supply is compressed again.

In this case, the pipes connected to the respective water reservoirs 17 may be provided with a valve for preventing backflow to prevent water from flowing back.

In the above state, when the vehicle suppresses the support plates 20 and 20 'to operate the operating lever 11, the rotary nozzle 10 is rotated by the operating lever and installed in the water reservoir 18 for injection. The valve is opened, which causes the water in the injection water reservoir 18 to move through the pipe as described above to be sprayed through the fixed nozzle and the rotary nozzle 10 to wash the tire. .

At this time, when the water in the spray water reservoir 18 is discharged by the compressed air, and the cleaning is completed, the pressure drops to the spray water reservoir, thereby compressing the water in the water reservoir 17 The pressure is to be introduced into the water reservoir 18 for injection again through the valve.

Raw water is connected to the water reservoir 17 as described above, and the water reservoir 18 for injection is provided on one side of the water reservoir 17 so that water is not used by using the water in the water reservoir 18 for injection. When the water is sent to the water reservoir (17) for injection at high speed by the pressure of the compressed air in the water reservoir (17), the time for storing water in the water reservoir for injection is shortened By doing so, you can do three-wheel work without waiting for the car.

That is, when the air compressed in the water reservoir 17 opens the valve, a pressure difference occurs. As a result, the water moves to the injection water reservoir 18 by the pressure in the water reservoir 17. When the water in the water reservoir 17 moves and the internal pressure drops, water is again supplied from the raw water pipe by the pump, so that the water reservoir 18 for injection can be supplied and stored in a short time.

On the other hand, the water reservoir 17 has been described in the case of using a connection to the water, but in this case there is a huge disadvantage of water consumption by continuing to discard the water, in order to solve this problem, to install the tank and the water and the sludge gathered to wash the tank It is possible to obtain the same effect as the present invention even if the water in the water tank to remove the sludge by installing a pump in the sludge is sent to the water reservoir.

That is, when the pump is operated to send the water in the water tank to the water reservoir, the water is introduced as much as the power of a certain punk acts to compress the air in the water reservoir, thereby obtaining the effect as described above.

Meanwhile, as shown in FIG. 7, the tires of the vehicle are lifted and the support plates 20, 20 ′ are separated from side to side, and then the water tank 3 is inserted and fixed in the washing station formed of concrete in the entrance of the construction site. When the support plates 20 and 20 'are placed on both sides of the upper side to fix the support plates 20 and 20', and the vehicle enters the upper portion of the support plate while connecting the support plates 20 and 20 'to the pump 5, the electric As the cleaning is done.

In other words, the water tank (3) where the water is stored and the support plates (20) and (20 ') where the tires are raised are separated from each other and then assembled and installed in the washing station formed at the entrance of the construction site. Its small volume and light weight make it easy to carry.

Meanwhile, as shown in FIG. 10, the water tank insertion unit and the three-wheel installation unit are molded by using concrete in the access road of the construction site, and in this state, the water tank insertion unit having the sludge removal unit is inserted into the water tank insertion unit, The steel plate 19 is formed to be bent in a wave form in the insert portion, but the steel plate is installed to be inclined in a tank square.

At this time, the steel plate 19 can withstand high loads by using a corrugated wave in multiple stages.

In the above state, the support plates 20 and 20 'are placed on the upper portion of the steel plate 19, but the pipe 21 is connected between the support plate 20 and the support plate 20' to form a channel for supplying water. What is necessary is to connect hydraulic pressure to the next cylinder 26.

And by installing the hydraulic pump 5 on one side of the support plate 20 and the pump on one side of the water tank (3) is to be operated by a sensor or a switch controlled by a control box.

In such a state, when the vehicle enters the support plates 20 and 20 ', the pump 5 is operated first by the switch for operating the pump 5 or by the sensor. When the water was sent to the water is sprayed to the tire through the nozzle 16 through the pipe 21 is to wash the dirt on the tire.

At the same time, the hydraulic pump 5 is operated, and the cylinder 26 is operated. As a result, the rod of the cylinder 26 is extended, so that the cylinder rod is connected by the fixing piece 25 of the chain 24. By moving the chain position, the rollers 22 are rotated by the double gears 23 connected to the chain, so that the tire located on the upper side of the roller 22 rotates to be washed.

Water injected into the tire through the nozzle 16 is dropped to the steel plate 19 is installed at the bottom and the water and sludge is installed to be inclined and fall to the water tank (3) on the waveform formed on the entire steel plate 19.

On the other hand, the water dropped into the tank 3 flows to the bottom through the through-hole of the sludge tank installed on the upper side of the tank, and the sludge sinks to the sludge tank by the load, so that the sludge is carried out to the outside by the conveyor which is a sludge removing device. Will be transported, the water collected in the tank (3) is to be reused by the pump.

When the cleaning is finished as described above, the car moves forward and the rear wheel is raised on the support plate, and in this state, the washing is performed again as described above.

 On the other hand, if you want to move the wheel, separate the pipe 21 connecting the support plate 20 and the support plate 20 'and then lift up the support plates 20, 20' on both sides, and again the steel plate 19 and the water tank (3) Separated and lifted, it is easy to carry without carrying a heavy load or a forklift.

Then, install the air pump in the washing machine mentioned in the third embodiment, connect with the pipe, install the check valve, and operate sequentially by the timer or use a separate program to finish the washing with water. It is also preferable to allow air to be supplied through the line so that water can be removed.

As described above, the present invention has been made by disassembling the washing machine, and the washing machine itself is configured by disassembling, so that it can be easily assembled and used at the construction site after disassembly and transportation, and the structure is simple and easy to manufacture. Because of its small volume, it is easy to transport, and because it uses concrete floor surface molded on the ground, it can be used regardless of the load of the truck.

That is, the present invention is made by disassembling the washing machine itself, it is easy to transport because it is composed of disassembly and termination is easy to manufacture by not using unnecessary beam, thereby reducing the manufacturing cost to the maximum.

In addition, the present invention is to wash the water and then by spraying the air is supplied through the line through which the water is injected, it is possible to remove the water on the tire, so that the maximum waste of water can be saved.

As described above, the present invention has been described in detail only with respect to the described embodiments, but it will be apparent to those skilled in the art that various modifications and changes are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended claims. will be.
