Description

Technical Field

[0001] This invention relates to the field of automated production technology for concrete paving bricks, and in particular to an automated production line and process for concrete paving bricks. Background Technology

[0002] The booming development of port construction has put forward higher quality requirements for the construction standards of port infrastructure. At the same time, the demand for some infrastructure products has also increased accordingly, especially the demand for concrete paving bricks, which are the main cement products in the construction of wharf storage yards. Concrete paving bricks are made by tightly arranging high-strength cement concrete precast blocks in a specific way. Under the action of external loads, the blocks are not subjected to force alone, but rather to interlocked and diffused loads. They have the following advantages: (1) They are inexpensive, easy to lay, anti-slip and anti-temperature deformation, and have low technical requirements for construction personnel, making them easy to construct; (2) They are highly adaptable to foundation settlement, can adapt to uneven foundation settlement, and have high vertical and horizontal resistance; (3) They are highly adaptable, can be opened for use immediately after construction, have a long service life, can be reused, have a higher residual value than other types of pavement, and are easy to maintain and renovate; (4) The blocks are mass-produced, with low cost, guaranteed product quality, and do not require the use of high-energy-consuming products such as asphalt, which meets the requirements of modern society for environmental protection, low carbon, energy conservation and emission reduction.

[0003] Traditional concrete paving brick production processes mostly use manual or semi-automatic equipment, resulting in a lack of fully automated production processes. This leads to problems such as high labor intensity for operators, low production efficiency, numerous overlapping operations, and safety hazards. Summary of the Invention

[0004] The purpose of this invention is to propose an automated production line and production process for concrete paving bricks, which effectively integrates and connects automated mechanical equipment to create an automated production line for concrete paving bricks, achieving good production results: the automated production line for concrete paving bricks realizes the automation of the entire process.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: This invention provides an automated production line for concrete paving bricks, comprising a product forming production line, a transfer and conveying production line, a finished product stacking production line, and an immersion curing production line connected in series. The product forming production line includes a batching machine, a mixer, a cement metering storage tank, an automatic forming machine, and a crusher. The transfer and conveying production line includes a plate receiving machine, a plate stacking machine, a first mother-daughter transfer car, and steel rails. The finished product stacking production line includes a second mother-daughter transfer car and a palletizing machine. The second mother-daughter transfer car is installed at the end of the rails in the storage area, and the palletizing machine is located at the end of the second mother-daughter transfer car. The immersion curing production line includes a curing tank and an automatic elevator installed in the curing tank.

[0006] Preferably, the mixer is equipped with a humidity sensor, which is used to sense the humidity inside the mixer.

[0007] Preferably, a curing shed is provided on the rail, the curing shed being used to cure the concrete pavement bricks to a strength of more than 50% of Cc50.

[0008] Preferably, a conveyor is provided between the first mother-daughter shuttle car and the stacking machine, the conveyor conveying the pallet and the concrete paving bricks on the pallet; a conveyor is provided between the second mother-daughter shuttle car and the palletizer, the conveyor conveying the pallet and the concrete paving bricks on the pallet.

[0009] Preferably, the palletizer is equipped with an automatically lifting rotating platform, the rotating platform having a rotation angle of 0°-360°, and multiple concrete paving bricks are stacked in layers and crosswise on the rotating platform.

[0010] The present invention also provides an automated production process for concrete paving bricks, which is applied to the automated production line for concrete paving bricks. The automated production process for concrete paving bricks includes the following steps: product forming production process, transshipment and handling production process, finished product stacking production process, and soaking and curing production process.

[0011] Preferably, the product molding process includes the following steps: 1.1) After the sand and gravel are metered by the batching machine, they are conveyed to the inside of the mixer by the conveyor belt. The sand and gravel are dry-mixed at a uniform speed for 30 seconds. Then water is added inside the mixer. The humidity inside the mixer is detected by the humidity sensor. The humidity sensor transmits the detected data signal to the controller. The controller controls the amount of water added until the humidity inside the mixer reaches the set humidity value. Then water addition can be stopped. 1.2) Add cement to the mixer and mix it with sand and gravel; this mixing process will make the cement evenly cover the surface of the sand and gravel, which is called "cement-coated sand". It can improve the bonding strength and later strength of cement products and save 10% of cement usage. 1.3) After mixing evenly, the humidity sensor detects the humidity inside the mixer. The humidity sensor transmits the detected data signal to the controller, which controls the amount of water added. Water addition is stopped once the humidity inside the mixer reaches the set humidity value. 1.4) After being stirred at a constant speed for 30 seconds, the hardened concrete is formed. It is then fed into the automatic molding machine through the lifting hopper. The machine is automatically pressed and molded according to the operating program set by the main unit of the automatic molding machine to obtain concrete paving bricks. The concrete paving bricks are then placed on the pallet. 1.5) Use a crusher to crush waste blocks and waste materials generated during the production process.

[0012] Preferably, the transshipment and handling production process includes the following steps: 2.1) The concrete paving bricks and pallets are transported to the stacking machine via the plate-jointing machine; 2.2) The concrete paving bricks and pallets are neatly stacked using a stacking machine until a set number of layers are reached and then stacking is stopped. 2.3) The stacked concrete paving bricks and pallets are transported to the first mother-daughter shuttle car by the conveyor. The first mother-daughter shuttle car senses the command, the daughter car separates from the mother car, and the daughter car moves forward along the track to the end of the conveyor to transport the stacked concrete paving brick products back to the mother car. 2.4) Concrete paving bricks and pallets are transported to designated rails via the mother car track for temporary storage; 2.5) A curing shed is set up on the rail to keep the concrete pavement bricks warm and moist for 24 hours. Curing is stopped after the concrete pavement bricks reach more than 50% of Cc50 strength.

[0013] Preferably, the finished code disk manufacturing process includes the following steps: 3.1) When the concrete paving bricks on the rails reach the preset strength value, the child car in the second mother-child shuttle car detaches from the mother car and goes to the storage area rail to transport the concrete paving bricks and pallets back to the mother car. Then the mother car delivers the concrete paving bricks and pallets to the front of the palletizer. 3.2) The front end of the palletizer is equipped with a lifting device, which lifts the concrete paving bricks and pallets onto the top conveyor belt of the palletizer, so that the concrete paving bricks and pallets are separated. The concrete paving bricks are automatically aligned on the conveyor belt, while the pallets are transported by a steel rail on one side to the product forming production line for recycling. 3.3) After the concrete paving bricks have been stacked to the set height, the stacking machine stops working. At this time, a forklift is used to remove the stacked concrete paving bricks from the stacking machine, and workers bundle and package them.

[0014] Preferably, the soaking and curing production process includes the following steps: Use a forklift to place the concrete paving bricks on the lifting soaking machine platform. The concrete paving bricks are lowered by the lift to the bottom of the curing pool (2100mm*1200mm*1500mm). After the concrete paving bricks are fully soaked for about 5 minutes, the lift will automatically rise. Use a forklift to remove the concrete paving bricks from the lift platform.

[0015] The beneficial effects of this invention include: This invention provides an automated production line and production process for concrete paving bricks. By optimizing and improving the four processes in the concrete paving brick production process, this invention effectively integrates and connects automated mechanical equipment to create an automated production line for concrete paving bricks, achieving good production results: This automated production line for concrete paving bricks realizes automated production of the entire process, effectively ensuring construction safety, greatly reducing the labor intensity of workers, improving the degree of production automation, effectively reducing costs, ensuring construction quality, improving construction efficiency, improving the construction environment, and effectively solving the environmental pollution problem during the construction process.

[0020] A humidity sensor is installed inside the mixer 2 to sense the humidity inside the mixer 2.

[0021] A curing shed 11 is installed on the rail. The curing shed 11 is used to cure the concrete pavement bricks to more than 50% of Cc50 strength.

[0022] A conveyor 12 is provided between the first mother-daughter shuttle car 7 and the stacking machine 6, and the conveyor 12 transports pallets and concrete paving bricks on the pallets; a conveyor 12 is provided between the second mother-daughter shuttle car 8 and the palletizer 9, and the conveyor 12 transports pallets and concrete paving bricks on the pallets.

[0023] The palletizer 9 is equipped with an automatically lifting rotating platform with a rotation angle of 0°-360°. Multiple concrete paving bricks are stacked in layers and crosswise on the rotating platform.

[0024] The present invention also provides an automated production process for concrete paving bricks, which is applied to the automated production line for concrete paving bricks. The automated production process for concrete paving bricks includes the following steps: product forming production process, transshipment and handling production process, finished product stacking production process, and soaking and curing production process.

[0025] The product molding process includes the following steps: 1.1) After being metered by the batching machine 1, the sand and gravel are conveyed to the mixer 2 by the conveyor belt. The sand and gravel are dry-mixed at a uniform speed for 30 seconds in the mixer 2. Then, water is added to the mixer 2. The humidity inside the mixer 2 is detected by the humidity sensor. The humidity sensor transmits the detected data signal to the controller. The controller controls the amount of water added until the humidity inside the mixer 2 reaches the set humidity value. Then, the water addition is stopped. 1.2) Add cement into the mixer 2 and mix it with sand and gravel; this mixing process will make the cement evenly cover the surface of the sand and gravel, which is called "cement-coated sand". It can improve the bonding strength and later strength of cement products and save 10% of cement usage. 1.3) After mixing evenly, the humidity inside the mixer 2 is detected by a humidity sensor. The humidity sensor transmits the detected data signal to the controller, which controls the amount of water added. Water addition is stopped when the humidity inside the mixer 2 reaches the set humidity value. 1.4) After being stirred at a constant speed for 30 seconds, the hardened concrete is formed. It is then fed into the automatic molding machine 4 through the lifting hopper. The machine is automatically pressed and molded according to the operating program set by the main unit 4 of the automatic molding machine to obtain concrete paving bricks, and the concrete paving bricks are placed on the pallet. 1.5) Use a crusher to crush waste blocks and waste materials generated during the production process.

[0026] The transshipment and handling production process includes the following steps: 2.1) The concrete paving bricks and pallets are conveyed to the stacking machine 6 via the plate-jointing machine; 2.2) The concrete paving bricks and pallets are neatly stacked using the stacking machine 6 until the set number of layers is reached and then stacking is stopped. 2.3) The stacked concrete paving bricks and pallets are transported to the first mother-daughter shuttle car 7 by the conveyor 12. The first mother-daughter shuttle car 7 senses the command, the daughter car separates from the mother car, and the daughter car moves forward along the track to the end of the conveyor 12 to transport the stacked concrete paving brick products back to the mother car. 2.4) Concrete paving bricks and pallets are transported to designated rails via the mother car track for temporary storage; 2.5) A curing shed 11 is set up on the rail. The curing shed 11 keeps the concrete pavement bricks warm and moist for 24 hours. Curing is stopped after the concrete pavement bricks reach more than 50% of Cc50.

[0027] like Figure 4 As shown, the maintenance shed 11 includes parallel and spaced-apart support platforms 21 on which concrete paving bricks can be stacked. A steel rail is provided between adjacent support platforms 21, along which a first tandem shuttle 7 can travel. A lift 22 is installed on the first tandem shuttle 7, and multiple stacking plates 23 can be placed sequentially from bottom to top on the lift 22, with multiple concrete paving bricks stacked on each plate 23. The first tandem shuttle 7, carrying the lift 22 and the concrete paving bricks, travels along the steel rail to between the two support platforms 21. Through the up-and-down movement of the lift 22, the stacking plates 23 and the concrete paving bricks can be moved above the two support platforms 21.

[0028] The distance between the two support platforms 21 is less than the length of the stacked plate 23, which allows the stacked plate 23 to overlap between the two support platforms 21. The two support platforms 21 can support the stacked plate 23 and the concrete paving bricks on the stacked plate 23, so that the concrete paving bricks can be stacked on the support platforms 21.

[0029] The finished code disc manufacturing process includes the following steps: 3.1) When the concrete paving bricks on the rails reach the preset strength value, the child car in the second mother-child shuttle car 8 separates from the mother car and goes to the storage area rail to transport the concrete paving bricks and pallets back to the mother car. Then the mother car delivers the concrete paving bricks and pallets to the front end of the palletizer 9. 3.2) The front end of the palletizer 9 is equipped with a lifting device. The lifting device lifts the concrete paving bricks and pallets onto the top conveyor belt of the palletizer 9, so that the concrete paving bricks and pallets are separated. The concrete paving bricks are automatically aligned on the conveyor belt, while the pallets are transported by a steel rail on one side to the product forming production line for recycling. The palletizer has a rotating platform at the end of its conveyor belt that can rotate 360° and automatically lift. When concrete paving bricks are placed on the platform in layers, the platform will automatically rotate 90° after each layer is placed. After being palletized by the palletizer, the concrete paving bricks are stacked in layers, which increases the stability of the concrete paving bricks and reduces safety hazards. 3.3) After the concrete paving bricks have been stacked to the set height, the stacking machine 9 stops working. At this time, a forklift is used to remove the stacked concrete paving bricks from the stacking machine 9, and workers bundle and pack them.

[0030] The soaking and curing production process includes the following steps: A forklift is used to place the concrete paving bricks on the lifting soaking machine platform. The concrete paving bricks are lowered by the lift to the bottom of curing tank 10 (2100mm*1200mm*1500mm). After the concrete paving bricks are fully soaked for approximately 5 minutes, the lift automatically rises, and the concrete paving bricks are removed from the lift platform using a forklift. At this point, the next packaged product enters curing tank 10, and the curing process is repeated cyclically.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
