Description

Technical Field

[0001] This utility model relates to the field of high slump concrete technology, and in particular to a tank truck and its cooling system for long-distance transportation of high slump concrete. Background Technology

[0002] Tanker trucks used for long-distance transport of high-slump concrete mainly consist of a rotating cylindrical tank and chassis. The tank's rotation helps maintain the uniformity of the concrete. Various types of cooling systems exist. Some employ four water tanks on the truck body, using water pumps, a main spray pipe, and nozzles to spray water onto the concrete tank for cooling. Hot water is then recycled to different tanks via return pipes, improving the cooling effect over extended periods. Others feature cooling systems including an air conditioning subsystem and an internal cooling subsystem. The air conditioning subsystem is located at the front of the truck and connects to the tanker's sandwich-structured storage tank via pipes to transmit cool air. The internal cooling subsystem is located inside the storage tank to further reduce the temperature of the concrete. These systems, combined with temperature monitoring and control systems, enable precise temperature monitoring and control of the cooling system.

[0003] A search revealed Chinese Patent Publication No. CN220947729U, which discloses an insulated concrete transport truck, belonging to the field of concrete transportation technology. The truck includes a tank body rotatably mounted on it and an insulation component detachably mounted on the tank body. This insulation component includes a first and second heat insulation plate spaced apart, a reflector plate disposed between the first and second heat insulation plates, at least one first elastic strip connecting the first heat insulation plate and the reflector plate, and at least one second elastic strip connecting the second heat insulation plate and the reflector plate. By setting the first and second heat insulation plates and the reflector plate, and connecting them respectively via the first and second elastic strips, the first and second heat insulation plates and the reflector plate can be fastened onto the tank body, achieving heat insulation of the tank body and reducing heat loss during concrete transportation. However, traditional cooling systems such as external tank spraying or interlayer refrigeration can only indirectly cool the concrete through the tank wall, making it difficult to quickly remove heat from the concrete interior, thus reducing concrete quality.

A discharge box is connected to the bottom left side of the mounting box, and nozzles are connected to the front and rear ends of the bottom of the discharge box. A discharge pipe is connected to the bottom right side of the tank. A cleaning component is installed on the left side of the driven bevel gear.

[0009] The above technical solution involves starting the first motor, stirring the cleaning fluid, and then using high-pressure spraying through the nozzles to flush the wastewater from the bottom, thus achieving automated deep cleaning of the tank and ensuring the quality of concrete transportation.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a tanker truck and its cooling system for long-distance transportation of high-slump concrete. The truck includes a body 1, a tank 7 mounted on top of the body 1, a mixing mechanism 3 installed inside the tank 7 to prevent excessive internal temperature, and a cleaning mechanism 2 installed on the outside of the tank 7 for cleaning the inside of the tank 7. The mixing mechanism 3 includes a second motor 301, which provides power to subsequent processes. The second motor 301 is mounted on the left side of the tank 7, and its output end is fixedly connected to a connecting... A connecting rod 302 is connected to a plurality of stirring blades 303 fixedly at equal intervals on the outer side of the connecting rod 302. A plurality of connecting square plates 307 are fixedly connected at equal intervals on the outer side of the left end of the connecting rod 302. A stirring rod 304 is fixedly connected to the right side of the connecting square plate 307. A mixing blade 305 is fixedly connected to the outer side of the stirring rod 304. Feeding devices 306 are installed on both the left and right ends of the top of the tank body 7. A cooling device 6 is installed at the rear right side of the vehicle body 1. A plurality of heat dissipation slots 8 are opened at equal intervals in the middle right side of the vehicle body 1. The installation of the cooling device 6 prevents the temperature inside the tank body 7 from becoming too high.

[0040] Specifically, during the transportation of high-slump concrete, the tank 7 on top of the vehicle body 1 is responsible for loading the concrete. The feeding devices 306 at the left and right ends of the top of the tank 7 can inject concrete. During transportation, if the internal temperature is too high, the cooling device 6 will sense it and activate the cooling function. Then, the second motor 301 is turned on, and its output end drives the connecting rod 302 to rotate, causing multiple mixing blades 303 on the outside of the connecting rod 302 to rotate accordingly, effectively mixing the concrete. At the same time, the connecting square plate 307 on the left side of the connecting rod 302 will drive the mixing rod 304 and the mixing blades 305 to rotate, further mixing the concrete to prevent the internal temperature of the tank 7 from becoming too high and to ensure the quality of the concrete.

[0041] Reference Figure 1 , Figure 3 and Figure 5The cleaning mechanism 2 includes a mounting box 209, which is installed on the top right side of the tank body 7. A first motor 201 is installed on the top of the mounting box 209. A connecting rod 202 is fixedly connected to the output end of the first motor 201. Multiple stirring rods 203 are fixedly connected at equal intervals to the outer side of the connecting rod 202. A connecting long rod 204 is fixedly connected to the bottom of the connecting rod 202. A driving bevel gear 205 is fixedly connected to the bottom of the connecting long rod 204. A driven bevel gear 206 is rotatably connected to the bottom of the right side of the tank body 7. The top of the driven bevel gear 206 meshes with the bottom of the driving bevel gear 205. A discharge box 210 is connected to the bottom left side of the mounting box 209. A nozzle 211 is connected to the front and rear ends of the bottom of the discharge box 210. A discharge pipe is connected to the bottom right side of the tank body 7. 208. A cleaning component 207 is installed on the left side of the driven bevel gear 206. The cleaning component 207 includes a threaded rod 2071, which is fixedly connected to the left side of the driven bevel gear 206. A connecting block 2073 is threadedly connected to the outer side of the threaded rod 2071. A scraper 2074 is fixedly connected to the outer side of the connecting block 2073. A limit rod 2072 is slidably connected to the middle of the connecting block 2073. The outer side of the scraper 2074 is slidably connected to the inner wall of the tank 7. The bottom of the connecting rod 202 passes through the mounting box 209 and the top of the tank 7 in sequence. A feed pipe 4 is provided on the top of the vehicle body 1. The bottom of the feed pipe 4 is connected to the top of the mounting box 209. A circular cover 5 is installed on the top of the feed pipe 4. The installation of the circular cover 5 prevents a large amount of dirt from entering from here.

[0042] Specifically, the first motor 201 starts, driving the connecting rod 202 at the output end to rotate. The stirring rod 203 on the outside of the connecting rod 202 rotates accordingly, stirring the cleaning liquid and thus improving the cleaning efficiency. As the connecting rod 202 rotates, the connecting rod 204 at its bottom and the active bevel gear 205 also begin to rotate. The active bevel gear 205 meshes with the driven bevel gear 206, causing the driven bevel gear 206 to rotate as well, causing the threaded rod 2071 to rotate. This, in turn, causes the connecting block 2073, which is threaded to it, to move in a straight line under the guidance of the limiting rod 2072. The scraper 2074 on the outside of the connecting block 2073 slides tightly against the inner wall of the tank 7, effectively cleaning the inner wall of the tank 7. At the same time, the cleaning liquid installed in the mounting box 209 is sprayed out through the discharge box 210 and nozzle 211 on the left side to thoroughly rinse the inside of the tank 7. The wastewater after cleaning is discharged through the discharge pipe 208 on the bottom right side of the tank 7, ensuring the cleaning effect of the tank 7.

[0043] Reference Figure 1 , Figure 2 and Figure 3The front and rear ends of the vehicle body 1 are rotatably connected to doors 9. A rearview mirror 10 is installed on the left side of the door 9. Multiple fixing plates 11 are fixedly connected at equal intervals on the lower front side of the vehicle body 1. Multiple tires 12 are installed at equal intervals on the bottom of the vehicle body 1.

[0044] Specifically, the installation of door 9 facilitates the use by staff, and the installation of fixing plate 11 facilitates the getting on and off of staff.

[0045] Working principle: When transporting high-slump concrete, the tank 7 on the top of the vehicle body 1 is responsible for loading the concrete. The feeding devices 306 on the left and right ends of the top of the tank 7 can inject concrete. During transportation, when the internal temperature is too high, the cooling device 6 is sensed and starts to cool. Then, the second motor 301 is turned on, and its output end drives the connecting rod 302 to rotate, so that the multiple mixing blades 303 on the outside of the connecting rod 302 rotate accordingly to mix the concrete. At the same time, the connecting square plate 307 on the left side of the connecting rod 302 drives the mixing rod 304 and the mixing blades 305 to rotate, further mixing the concrete, avoiding excessive internal temperature of the tank 7 and ensuring the quality of the concrete.

[0046] The first motor 201 starts, driving the connecting rod 202 at the output end to rotate, causing the stirring rod 203 on the outside of the connecting rod 202 to stir the cleaning liquid, enhancing the cleaning effect. The connecting rod 204 and the active bevel gear 205 at the bottom of the connecting rod 202 rotate accordingly. The active bevel gear 205 meshes with the driven bevel gear 206, driving the driven bevel gear 206 to rotate, which in turn causes the threaded rod 2071 to rotate. This causes the connecting block 2073 with the outer threaded connection to move linearly under the restriction of the limiting rod 2072. The scraper 2074 on the outside of the connecting block 2073 slides along the inner wall of the tank 7 to clean the inner wall of the tank 7. At the same time, the cleaning liquid in the installation box 209 is sprayed out through the discharge box 210 on the left and the nozzle 211 to rinse the inside of the tank 7. The wastewater after cleaning is discharged through the discharge pipe 208 on the bottom right of the tank 7, achieving the cleaning effect of the tank 7.
