Description

Technical Field

[0001] This invention relates to the field of construction equipment, and more specifically to a mobile concrete production and quality inspection station. Background Technology

[0002] Concrete is an artificial stone material made by mixing and hardening cement, sand, stone, water, and admixtures in a certain proportion. Cement hydration binds the aggregates to form a solid whole, with high compressive strength, good durability, and can be molded into various shapes. It is the core structural material with the largest usage and widest application in modern civil engineering.

[0003] After concrete is produced by the manufacturer, it needs to be transported to the construction site by mixer truck. However, if it is transported over a long distance, the quality of the concrete will be reduced due to factors such as long distance and bad weather, which will affect the quality of the project. However, if concrete is mixed on-site, there will be many environmental interferences and no real-time testing methods, making it impossible to make timely adjustments, and the quality of the concrete obtained will be very limited. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a mobile concrete production and quality inspection station that can prepare high-quality concrete on-site and make full use of the limited space of the flatbed truck bed, so as to solve the problem of reduced concrete quality caused by long-distance transportation of concrete.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a truck head and a flatbed truck bed that moves under the traction of the truck head; two enclosed mixing chambers and a enclosed testing chamber are fixedly arranged sequentially from front to back above the flatbed truck bed; each of the enclosed mixing chamber and the enclosed testing chamber is equipped with a temperature regulating device for adjusting the internal temperature; a mixer is installed inside the enclosed mixing chamber; a feeding device for feeding material to the mixer is installed above the enclosed mixing chamber; an output device for outputting concrete to the outside of the enclosed mixing chamber without entering the enclosed mixing chamber and a sampling device for sampling concrete into a sealed container without entering the enclosed mixing chamber are installed on the side of the enclosed mixing chamber; a testing device for testing the sampled concrete is installed inside the enclosed testing chamber; and a stabilizing device for providing a stable working environment for the mixer and the testing device is installed below the flatbed truck bed.

[0006] By adopting the above technical solution, upon arrival at the site, the stabilizing device provides a stable working environment for the mixer and testing equipment. Workers measure and sequentially feed different materials (in conjunction with a crane) into the mixer inside the closed mixing chamber via a feeding device above it. The mixer then mixes the materials. During mixing, a sampling device takes samples from the mixer, which are then monitored in real-time by the testing equipment. Adjustments are made in real-time based on the monitored structure through water / material replenishment. Finally, the completed concrete is output to the outside of the closed mixing chamber via an output device. The above equipment offers the following advantages: ① The closed testing chamber and closed mixing chamber are mobile, not restricted by site conditions, making them convenient and efficient to move; ② Testing and mixing are both completed in a closed environment, equipped with temperature control and stabilizing devices, greatly reducing the impact of external dust / temperature / humidity on testing and mixing, ensuring concrete quality; ③ The closed mixing chamber uses an output device to output concrete and a sampling device to sample concrete, eliminating the need to enter the closed mixing chamber during output and sampling processes, thus avoiding pollution and changes in the working environment caused by repeated entry and exit, further ensuring concrete quality; ④ Compared to concrete transported over long distances after being configured by the manufacturer... This solution allows for on-demand mixing, avoiding concrete quality degradation due to long transportation distances and preventing concrete waste caused by reserved transportation allowances; ⑤ The two closed mixing chambers are rationally arranged, with one chamber being configured while the other is discharging, effectively ensuring project progress; ⑥ The top is chosen as the installation location for the feeding device, making full use of space and rationally utilizing the material's own weight, simplifying the structure; ⑦ The closed mixing chamber and the closed testing chamber are independent modules with no connecting passage between them, which not only provides a closed environment but also facilitates combination, replacement, and upgrades, maximizing space utilization.

[0007] The present invention is further configured such that: the mixer is closely attached to the side wall of the closed mixing chamber; the sampling device includes a sampling pipe, one end of which is connected to the mixer, and the other end passes through the side wall of the closed mixing chamber and bends downward; a sampling gate valve for controlling the opening and closing of the sampling pipe is provided on the outside of the side wall of the closed mixing chamber.

[0008] By adopting the above technical solution, when sampling is required, the staff first places the sampling container at the outer end of the sampling pipe located outside the closed mixing chamber, opens the sampling gate valve, and under the action of gravity, the concrete flows from the sampling pipe into the sampling container. When the sampling container is about to be full, the sampling container is sealed and the sampling gate valve is closed at the same time. This achieves rapid sampling and sealed transfer to the closed testing chamber without entering the closed mixing chamber, avoiding repeated entry and exit from the closed mixing chamber, which would cause pollution and fluctuations in the working environment inside the closed mixing chamber. In addition, the mixer, which is close to the side wall of the closed mixing chamber, effectively prevents residual concrete from blocking the sampling pipe. After the sampling gate valve is closed, the sampling pipe can be cleaned from the outside.

[0009] The present invention is further configured such that: the feeding device includes a feeding hopper located above and a feeding pipe located below connecting the feeding hopper and the mixer; the upper end of the feeding hopper is located above the closed mixing chamber and is provided with a closed cover plate; a feeding motor is provided above the closed cover plate; a feeding screw extending to the feeding pipe and pushing the raw material downward is driven below the feeding motor; and a manual feeding port and a feeding cover plate for opening or closing the manual feeding port are provided on the side of the closed cover plate located on the feeding motor.

[0010] By adopting the above technical solution, the workers put the weighed raw materials into the feeding hopper through the manual feeding port. The raw materials will be temporarily stored in the feeding hopper. As the feeding screw is transmitted, the raw materials will gradually enter the mixer through the feeding pipe. On the one hand, the feeding rate of raw materials is slowed down, making the concrete easier to mix. On the other hand, the height difference of feeding is reduced, dust is controlled, and the internal structure of the mixer is protected while protecting the workers and extending its service life.

[0011] The present invention is further configured such that: the output device includes an output pipe passing through and connected to the bottom of the mixer, one end of the output pipe being located outside the closed mixing chamber as an output end, and the other end being located inside the closed mixing chamber as a pushing end, the pushing end being provided with a feeding motor, and the feeding motor driving a feeding screw along the output pipe to push the concrete toward the output end.

[0012] By adopting the above technical solution, after the concrete mixed by the mixer falls into the output pipe, the feeding motor drives the feeding screw to rotate, thereby pushing the concrete to the output end outside the closed mixing chamber. While stably pushing the concrete, it effectively prevents the closed mixing chamber from connecting with the outside, maintains the closed state of the closed mixing chamber, and thus ensures the quality of the concrete.

[0013] The present invention is further configured such that: on the other side of the closed mixing chamber relative to the output end, there is a maintenance door for entering and exiting the closed mixing chamber and a feeding ladder for workers to climb to the top of the closed mixing chamber to feed materials.

[0014] By adopting the above technical solution, the output end is avoided and operating space is reserved around the output end. Therefore, the maintenance door and feeding ladder are designed to be on the other side, which makes reasonable use of space and facilitates the entry and exit of staff.

[0015] The present invention is further configured such that: a water supply pipe is provided in the closed mixing chamber, one end of the water supply pipe is located on the side of the closed mixing chamber and is provided with a water supply connector for connecting to the construction site water source, and the other end is connected to the mixer; the water supply pipe is provided with a control valve and a flow sensor for detecting the amount of water entering the chamber.

[0016] By adopting the above technical solution, the water source at the construction site is used to supply water to the mixer, saving the space and weight occupied by transporting water. With the help of control valves and flow sensors, the water intake of the mixer can be accurately controlled, thereby ensuring the quality of concrete.

[0017] The present invention is further configured such that the temperature control device includes an air conditioning unit respectively disposed above the closed mixing chamber and the closed testing chamber.

[0018] By adopting the above technical solution and using the mature air conditioning unit, the internal temperature of the closed mixing chamber and the closed testing chamber can be regulated, making the temperature regulation more efficient and accurate. The space above the closed mixing chamber and the closed testing chamber can also be used to install the air conditioning unit, thus making the space utilization rate higher.

[0019] The present invention is further configured such that: the stabilizing device includes hydraulic outriggers respectively installed under the flatbed truck bed and equidistantly distributed in the front-rear direction; the hydraulic outriggers include hydraulic cylinders fixed under the flatbed truck bed; a piston rod is driven to extend and retract relative to the hydraulic cylinder below the hydraulic cylinder; and a support plate is fixedly provided at the lower end of the piston rod to support the ground.

[0020] By adopting the above technical solution, upon arrival at the construction site, multiple hydraulic cylinders simultaneously drive the piston rods to extend downwards until the support plate rests on the ground, thereby forming a stable flatbed truck support structure. This provides a stable working environment for the mixer and testing equipment, ensuring testing accuracy and concrete quality.

[0021] The present invention is further configured such that: an entrance and exit door for entering and exiting the closed testing chamber is provided at the rear of the closed testing chamber, and an entrance and exit ladder is provided below the entrance and exit door for the closed testing chamber.

[0022] By adopting the above technical solution, the entrance and exit of the closed testing room is designed to be located at the rear of the closed testing room, and is equipped with an entrance and exit ladder, which makes reasonable use of space and makes entry and exit more convenient.

[0026] like Figure 1 — Figure 5As shown, this invention discloses a mobile concrete production and quality inspection station, including a truck head 1 and a flatbed truck bed 2 that moves under the traction of the truck head 1. Two enclosed mixing chambers 3 and a enclosed testing chamber 4 are fixedly arranged sequentially from front to back above the flatbed truck bed 2. The enclosed mixing chambers 3 and 4 are each equipped with a temperature regulating device to adjust their internal temperature. A mixer 31 is installed inside the enclosed mixing chamber 3. A feeding device for feeding material into the mixer 31 is installed above the enclosed mixing chamber 3. An output device for outputting concrete to the outside of the enclosed mixing chamber 3 without entering the enclosed mixing chamber 3 and a sampling device for sampling concrete into a sealed container without entering the enclosed mixing chamber 3 are installed on the side of the enclosed mixing chamber 3. A testing device for testing the sampled concrete is installed inside the enclosed testing chamber 4. The testing device is not shown in the attached drawings, but can be determined based on... Select commercially available testing equipment according to requirements, including but not limited to pressure testing machines, electric flexural strength testing machines, slump cones and matching tamping rods, air content analyzers, etc. A stabilizing device is installed under the flatbed truck bed 2 to provide a stable working environment for the mixer 31 and the testing equipment. After arriving at the site, the stabilizing device provides a stable working environment for the mixer 31 and the testing equipment. The staff measures and sequentially feeds different materials (in conjunction with the crane) into the mixer 31 inside the closed mixing chamber 3 from the feeding device above the closed mixing chamber 3. The mixer 31 mixes the materials. During the mixing process, a sampling device takes samples from the mixer 31, which are then tested in real time by the testing equipment. The system is adjusted in real time by adding water / material according to the test results. Finally, the completed concrete is output to the outside of the closed mixing chamber 3 through the output device. The above-mentioned equipment has the following advantages: ① The enclosed testing chamber 4 and the enclosed mixing chamber 3 are mobile and not restricted by site, making them convenient and efficient to move; ② Testing and mixing are both completed in a closed environment, equipped with temperature control and stabilization devices, which greatly reduces the impact of dust / temperature / humidity in the external environment on testing and mixing, ensuring concrete quality; ③ The enclosed mixing chamber 3 uses an output device to output concrete and a sampling device to sample concrete. The output and sampling processes do not require entering the enclosed mixing chamber 3, eliminating the pollution and changes in the working environment caused by repeated entry and exit, further ensuring concrete quality; ④ Compared to concrete transported over long distances after being configured by the manufacturer... This solution allows for on-demand preparation and use, avoiding concrete quality degradation due to long transportation distances and preventing concrete waste caused by reserving transportation allowances; ⑤ The two closed mixing chambers 3 are rationally arranged, with one closed mixing chamber 3 being configured while the other is outputting, effectively ensuring project progress; ⑥ The top is chosen as the installation location for the feeding device, making full use of space and rationally utilizing the material's own weight, simplifying the structure; ⑦ The closed mixing chamber 3 and the closed testing chamber 4 are independent modules, with no connecting passage between them, which not only facilitates providing a closed environment but also makes it easy to combine, replace, and upgrade, maximizing space utilization.

[0027] The mixer 31 is closely attached to the side wall of the closed mixing chamber 3. The sampling device includes a sampling pipe 32, one end of which is connected to the mixer 31, and the other end passes through the side wall of the closed mixing chamber 3 and bends downward. A sampling gate valve 321 is installed on the outside of the side wall of the closed mixing chamber 3 to control the opening and closing of the sampling pipe 32. When sampling is required, the staff first places the sampling container at the outer end of the sampling pipe 32 located in the closed mixing chamber 3, and opens the sampling gate valve 321. Under the action of gravity, concrete flows from the sampling pipe 32 into the sampling container. When the sampling container is about to be filled, the sampling container is sealed and the sampling gate valve 321 is closed at the same time. This achieves rapid sampling and sealed transfer to the closed testing chamber 4 without entering the closed mixing chamber 3, avoiding repeated entry and exit from the closed mixing chamber 3, which would cause pollution and fluctuations in the working environment inside the closed mixing chamber 3. In addition, the mixer 31, which is closely attached to the side wall of the closed mixing chamber 3, effectively prevents residual concrete from blocking the sampling pipe 32. After the sampling gate valve 321 is closed, the sampling pipe 32 can be cleaned from the outside.

[0028] The feeding device includes a feeding hopper 33 located at the top and a feeding pipe 34 located at the bottom connecting the feeding hopper 33 and the mixer 31. The upper end of the feeding hopper 33 is located above the enclosed mixing chamber 3 and is provided with a sealing cover 331. A feeding motor 332 is provided above the sealing cover 331. A feeding screw 333 extending to the feeding pipe 34 and pushing the raw materials downward is driven below the feeding motor 332. The sealing cover 331 is located on the side of the feeding motor 332 and is provided with a manual feeding port 334 for opening or closing. With the feeding cover 335 of the manual feeding port 334 closed, the worker puts the weighed raw materials into the feeding hopper 33 through the manual feeding port 334. The raw materials will be temporarily stored in the feeding hopper 33. As the feeding screw 333 transmits the material, the raw materials will gradually enter the mixer 31 through the feeding pipe 34. On the one hand, this slows down the feeding rate of the raw materials, making the concrete easier to mix. On the other hand, it reduces the height difference of the feeding, controls dust, protects the workers, and protects the internal structure of the mixer 31, extending its service life.

[0029] The output device includes an output pipe 35 that passes through and connects to the bottom of the mixer 31. One end of the output pipe 35 is located outside the closed mixing chamber 3 as the output end 351, and the other end is located inside the closed mixing chamber 3 as the pushing end 352. The pushing end 352 is equipped with a feeding motor 353. The feeding motor 353 drives a feeding screw 354 along the output pipe 35 to push the concrete to the output end 351. After the concrete mixed by the mixer 31 falls into the output pipe 35, the feeding motor 353 drives the feeding screw 354 to rotate, thereby pushing the concrete to the output end 351 outside the closed mixing chamber 3. While stably pushing the concrete, it effectively prevents the closed mixing chamber 3 from connecting with the outside, keeps the closed mixing chamber 3 in a closed state, and thus ensures the quality of the concrete.

[0030] On the other side of the closed mixing chamber 3 opposite to the output end 351, there is a maintenance door 36 for entering and exiting the closed mixing chamber 3 and a feeding ladder 37 for workers to climb to the top of the closed mixing chamber 3 to feed materials. To avoid the output end 351 and to reserve operating space around the output end 351, the maintenance door 36 and the feeding ladder 37 are designed to the other side, which makes reasonable use of space and facilitates workers to enter, exit and go up and down.

[0031] A water supply pipe 38 is installed inside the closed mixing chamber 3. One end of the water supply pipe 38 is located on the side of the closed mixing chamber 3 and is equipped with a water supply connector 381 for connecting to the water source at the construction site. The other end is connected to the mixer 31. The water supply pipe 38 is equipped with a control valve 382 and a flow sensor 383 for detecting the water intake. The water source at the construction site is used to supply water to the mixer 31 in a reasonable way, saving the space and weight occupied by transporting water. With the control valve 382 and the flow sensor 383, the water intake of the mixer 31 is precisely controlled, thereby ensuring the quality of concrete.

[0032] The temperature control device includes an air conditioning unit 5 installed above the closed mixing chamber 3 and the closed testing chamber 4 respectively. The air conditioning unit 5, which is now a technologically mature device, is used to regulate the internal temperature of the closed mixing chamber 3 and the closed testing chamber 4, making the temperature regulation more efficient and accurate. It also makes reasonable use of the space above the closed mixing chamber 3 and the closed testing chamber 4 to install the air conditioning unit 5, thus making the space utilization rate higher.

[0033] The stabilizing device includes hydraulic outriggers installed under the flatbed truck bed 2 and equidistantly distributed along the front-to-back direction. Each hydraulic outrigger includes a hydraulic cylinder 21 fixed under the flatbed truck bed 2. A piston rod 211 is driven to extend and retract relative to the hydraulic cylinder 21 below the hydraulic cylinder 21. A support plate 212 supporting the ground is fixed at the lower end of the piston rod 211. Upon arrival at the construction site, multiple hydraulic cylinders 21 simultaneously drive the piston rod 211 to extend downward until the support plate 212 supports the ground, thereby forming a stable support structure for the flatbed truck bed 2. This provides a stable working environment for the mixer 31 and testing equipment, ensuring testing accuracy and concrete quality.

[0034] An entrance / exit door 41 is provided at the rear of the closed testing chamber 4. An entrance / exit ladder is provided below the entrance / exit door 41. The entrance / exit door 41 is designed at the rear of the closed testing chamber 4 and is combined with the entrance / exit ladder to make reasonable use of space and make entry and exit more convenient.
