Description

Technical Field

[0001] This invention relates to a production line for concrete piles. Background Technology

[0002] Prestressed centrifugal concrete piles using the pre-tensioning method are an important foundation material in my country, belonging to the field of concrete products technology. Their factory production can be traced back to the 1960s. In the 1980s, as a heavy precast component, its main manufacturing processes included cutting steel bars to length, forming steel cages, installing end plates, tensioning plates, and anchor plates, placing the steel cage with end plates into the bottom mold, cleaning the upper and bottom molds, applying a release agent, mixing concrete, placing the concrete, closing the mold, tensioning, centrifugal molding, steam curing, and demolding. To achieve factory production of centrifugal precast piles, we need to arrange each process according to production efficiency and safety to form a reasonable production line. Since the advent of centrifugal piles, production line design has been a key consideration for professionals in the industry and a crucial part of the centrifugal concrete pile production process. The rationality of the production line affects product quality, production safety, production efficiency, labor intensity, and now also energy conservation, environmental protection, and the foundation for automated and intelligent production.

[0003] The urgent task is to design a reasonable automated and intelligent production line for the transportation of molds for centrifugal concrete piles; otherwise, precast pile companies will run out of workers in three to five years.

[0004] In response to the aforementioned situation, a Chinese utility model patent, ZL201821089916.9, entitled "Centrifugal Concrete Pile Production Line," discloses a production line layout including a feeding and molding area, a centrifugation area, and a curing area. Its features include: a mold transport vehicle and sequentially adjacent first, second, and third span workshops; a first area for placing the cured pile molds within the first span workshop; a second area for hoisting the upper half of the mold within the second span workshop; and a third area for installing the reinforcing cage onto the lower half of the mold within the third span workshop; or, a third area for installing the reinforcing cage onto the lower half of the mold within the second span workshop; and a second area for hoisting the upper half of the mold within the third span workshop. The mold transport vehicle can travel back and forth between the first and second span workshops along the mold's length direction, and also between the second and third span workshops along the mold's length direction. The first, second, and third areas constitute the demolding area. Equipment for dismantling anchor plates and tension plates at the ends of concrete piles is provided in the second area or the third area.

[0005] However, the aforementioned patent still has the following shortcomings: the original pile demolition equipment (equipment for dismantling the anchor plates and tension plates at the ends of concrete piles) is placed in the demolition area, resulting in numerous processes in the demolition area. There are both mold cleaning equipment and pile demolition equipment for dismantling plate parts, which poses a danger to personnel. The equipment interferes with each other, the process is not smooth, the smoothness is unclear, it is difficult to achieve balanced production, resulting in low efficiency and the inability to achieve good overall planning.

[0006] Therefore, the aforementioned production line can be further optimized. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a concrete pile production line with a reasonable layout that ensures orderly operation of pile demolition and production, in order to improve the automation level of concrete pile production.

[0008] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a concrete pile production line, including a steel cage installation area and a formwork removal area; characterized in that: it further includes a pile removal area for removing the plates at the ends of the concrete piles, wherein the pile removal area and the steel cage installation area are both adjacent to the formwork removal area and are both located behind the formwork removal area, and the steel cage installation area is adjacent to the pile removal area and is located on the right side of the pile removal area.

[0009] Further optimization involves providing a left plate conveying line within the aforementioned pile dismantling area to transport plates dismantled from the left side of the concrete pile to the left side of the rebar cage installation area, and a right plate conveying line to transport plates dismantled from the right side of the concrete pile to the right side of the rebar cage installation area. The left and right plate conveying lines extend into the rebar cage installation area, and the ends of the left and right plate conveying lines are spaced apart. Because the plates at both ends of the concrete pile are tensioning plates and anchoring plates, in the production line, the tensioning device is located on one side of the tensioning zone, and the installation position of the tensioning plate in the rebar cage installation zone must be uniform, generally on the right side as shown in the diagram. This ensures that after the rebar cage is hoisted onto the bottom formwork in the tensioning zone, the tensioning plate is positioned on one side of the tensioning device. This solution automatically transports the plates removed from the left end of the concrete pile in the pile removal zone to the left end of the rebar cage installation zone via a left plate conveyor line, and the plates removed from the right end of the concrete pile in the pile removal zone to the right end of the rebar cage installation zone via a right plate conveyor line. Therefore, the operator can directly install the corresponding plates onto the rebar cage in the rebar cage installation zone, ensuring that the tensioning plate is installed on the corresponding side of the rebar cage, further ensuring a smooth, clear, and efficient process.

[0010] The formwork removal area is relatively long in the left-right direction, while the steam curing area, pile removal area, and rebar cage installation area are relatively short in the left-right direction. The overall length of these three areas is roughly the same as the overall length of the formwork removal area. To further improve the layout and make it more rational, a steam curing area is located behind the formwork removal area, and the pile removal area is situated between the rebar cage installation area and the steam curing area. This structure arranges these three areas along the left-right direction, making full use of the site space and resulting in a more rational layout.

[0011] To reduce costs and make full use of the site space, the aforementioned pile demolition area is equipped with multiple concrete pile placement platforms spaced at intervals from front to back. Left and right pile demolition vehicle tracks are located on the left and right sides of each platform, respectively. The left track carries left pile demolition equipment that can move back and forth, and the right track carries right pile demolition equipment that can move back and forth. The pile demolition area utilizes two pile demolition devices, which can move back and forth. After removing a plate from the end of a concrete pile on one platform, the demolition device can move to the corresponding position on the next adjacent platform to remove the plate. This solution eliminates the need for multiple pile demolition devices, effectively reducing costs. After demolishing one pile, it can be transported out, and the next pile can be brought in. Simultaneously, the demolition device moves to the next workstation for demolition, resulting in a very smooth overall process and significantly improving pile demolition efficiency.

[0012] Because concrete piles vary in length, and the pile-dismantling equipment at both ends is spaced at a fixed interval, a fixed concrete pile placement platform would prevent the dismantling of piles of varying lengths. To address this issue, a further improvement is made: the concrete pile placement platform is a pile-transporting platform that moves left and right along a preset trajectory. If the concrete pile is short, the platform can first move left and right to one end for dismantling, and then move left and right to the other end for dismantling by the equipment at that end. This layout allows for the use of concrete piles of different lengths, is more rational, and has better adaptability.

[0013] Further improvements include a rebar cage manufacturing area, which houses the rebar cage manufacturing equipment. The rebar cage installation area and pile dismantling area are both located between the formwork removal area and the rebar cage manufacturing area. The rebar cage manufacturing area is situated behind and adjacent to the rebar cage installation area and pile dismantling area, shortening the transportation route, optimizing the production line, improving efficiency, and resulting in a rational regional layout.

[0014] During the process of hoisting the concrete piles from the pile-removal area, to prevent them from falling and damaging the rebar cage manufacturing equipment or potentially injuring operators, a further improvement has been made. A protective platform is installed in the rebar cage manufacturing area, with the rebar cage manufacturing equipment located below it. This ensures that even if a concrete pile falls during hoisting, it will impact the protective platform, which provides a safety guarantee.

[0015] Alternatively, a pile exit ramp can be provided to transport the concrete piles towards the steam curing area, adjacent to both the pile removal area and the steam curing area. This scheme specifies a particular pile exit direction, which can be either left-right or front-back. If the piles are exited in a front-back direction, they can be lifted out, eliminating the need for a pile exit ramp.

[0016] To facilitate lifting, further improvements have been made, including a first lifting and hoisting device. This first lifting and hoisting device is used to lift concrete piles from the demolding area to the demolition area and to remove concrete piles from the demolition area. This first lifting and hoisting device is only responsible for transporting in the front-to-back direction, and its working route is clear and straightforward.

[0017] To facilitate lifting, a second lifting device is also included. This second lifting device is used to lift molds with concrete piles into the steam curing area and to lift molds with concrete piles from the steam curing area to the demolding area. This second lifting device is only responsible for transporting materials in the forward and backward direction, and its working route is clear and straightforward. Furthermore, the operating tracks of the first and second lifting devices are independently set and parallel to each other, allowing the lifting equipment in each workshop to independently complete its respective processes, avoiding interference between the lifting equipment during production and making the production process smoother.

[0018] Compared with the prior art, the advantages of this invention are: the function of dismantling the piling plate is separated from the demolding area, forming a piling dismantling area that is independent of the demolding area. The process in the demolding area is greatly simplified. After the corresponding equipment in the demolding area is reduced, the mutual interference between the equipment is greatly reduced. The process in the demolding area is clear and smooth, achieving balanced production and greatly improving processing efficiency. It also achieves reasonable overall planning. Since the mold transport trolley in the demolding area needs to move back and forth, after separating the demolding process from the demolding area, the demolding area can achieve automatic unmanned operation, effectively avoiding personnel danger. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the structure of an embodiment of the present invention; Figure 2 This is a schematic diagram of the structure of the demolding and pile-removal area in an embodiment of the present invention. Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 , 2 The image shown is a preferred embodiment of the present invention.

[0022] A concrete pile production line includes a rebar cage installation area A and a demolding area B. Demolding area B is mainly used for processes such as placing and releasing the molds and removing the upper mold. Demolding area B can also be used to clean the bottom mold; details can be found in the background patent. The rebar cage installation area is used to install end plates and other plates at both ends of the rebar cage. Generally, anchor plates are installed on the left side of the rebar cage, and tensioning plates are installed on the right side.

[0023] It also includes a pile removal area C for disassembling the plates at the ends of the concrete piles. Both the pile removal area C and the reinforcing cage installation area A are adjacent to and located behind the formwork removal area B. The reinforcing cage installation area A is adjacent to and located to the right of the pile removal area C. The plates include anchor plates and tension plates, which are essential components in the prestressed concrete pile production process. Specific details can be found in existing technologies, and end plates may also be included.

[0024] By separating the functions of the plates at both ends of the demolding area from the demolding area B, a demolding area C is formed that is independent of the demolding area B. The processes in the demolding area B are greatly simplified. With the reduction of corresponding equipment in the demolding area B, the mutual interference between the equipment is greatly reduced. The processes in the demolding area B are clear and smooth, achieving balanced production and greatly improving processing efficiency. Reasonable overall planning is also achieved. Since the mold transport trolley in the demolding area B needs to move back and forth, after separating the demolding process from the demolding area B, the demolding area B can achieve automatic unmanned operation, effectively avoiding personnel hazards.

[0025] Another important improvement is that the pile removal area C is equipped with a left plate conveying line 1a for transporting plates dismantled from the left side of the concrete pile to the left side of the rebar cage installation area A, and a right plate conveying line 1b for transporting plates dismantled from the right side of the concrete pile to the right side of the rebar cage installation area A. The left and right plate conveying lines 1a and 1b extend into the rebar cage installation area A, with the terminals 11 and 12 of the left and right plate conveying lines spaced apart. Generally, the left side of the concrete pile is the anchor plate, and the right side is the tensioning plate. However, their positions can be interchanged.

[0026] The left plate conveyor line 1a and the right plate conveyor line 1b can use conventional conveying mechanisms such as conveyor belts, conveyor chains, conveyor rollers, and conveyor lines with hooks.

[0027] A steam curing zone D is located behind the formwork removal zone B, and the pile removal zone C is located between the steel cage installation zone A and the steam curing zone D.

[0028] The pile demolition area C is equipped with multiple concrete pile placement platforms 2 spaced apart from front to back. Each concrete pile placement platform 2 has a left pile demolition vehicle track 3a and a right pile demolition vehicle track 3b on its left and right sides, respectively. The left pile demolition vehicle track 3a is equipped with a left pile demolition device 4a that can move back and forth, and the right pile demolition vehicle track 3b is equipped with a right pile demolition device 4b that can move back and forth. The concrete pile placement platform 2 is a pile transport platform that moves left and right along a preset trajectory. The preset trajectory can be completed via a track 21 set on the ground. The pile transport platform can be a pile transport vehicle. The pile demolition equipment can be a pneumatic hammer or an electric wrench, etc. If the concrete pile is short, the pile transport platform can first move left and right to one end to demolish the plates on the pile, and then move left and right to the other end so that the pile demolition equipment at the other end can demolish the plates on the pile.

[0029] It also includes a rebar cage manufacturing area E, which contains rebar cage manufacturing equipment 5. The rebar cage installation area A and the pile dismantling area C are both located between the formwork removal area B and the rebar cage manufacturing area E. The rebar cage manufacturing area E is equipped with a protective platform 6 that is suspended in the air, and the rebar cage manufacturing equipment 5 is located below the protective platform 6.

[0030] It also includes a first lifting and hoisting device 8a and a second lifting and hoisting device 8b. The first lifting and hoisting device 8a is used to hoist the concrete piles in the demolding zone B to the demolding zone C, and to remove the concrete piles in the demolding zone C. The second lifting and hoisting device 8b is used to hoist the molds with concrete piles to the steam curing zone D, and to remove the molds with concrete piles in the steam curing zone D and move them to the demolding zone B.

[0031] The working principle and process of this concrete pile production line embodiment are as follows: The centrifugally formed mold with concrete piles is first lifted to the steam curing zone D by the second lifting and hoisting equipment 8b for steam curing. After steam curing, the mold with concrete piles in the steam curing zone D is lifted away and moved to the demolding zone B. Tensioning is performed in the demolding zone, and the mold is moved to the rear of the pile demolition zone C. The upper mold is lifted away, and the first lifting and hoisting equipment 8 lifts the concrete pile with plates at both ends from the demolding zone B to the pile demolition zone C for pile demolition. The left pile demolition equipment 4a removes the anchor plate at the left end of the concrete pile and places it on the left plate conveyor line 1a. The right pile demolition equipment 4b removes the tension plate at the right end of the concrete pile and places it on the right plate conveyor line 1b.

[0032] After the pile demolition is completed, the concrete piles are lifted from pile area C by the first lifting and hoisting equipment 8 and transported to the rear for pile exit.

[0033] The anchor plate is conveyed to the left side of the rebar cage installation area A via the left plate conveyor line 1a, and the tensioning plate is conveyed to the right side of the rebar cage installation area A via the right plate conveyor line 1b. The anchor plate can then be installed on the left side of the rebar cage, and the tensioning plate on the right side. The rebar cage with the end plates, tensioning plate, and anchor plates installed is then hoisted onto the cleaned bottom formwork in the demolding area using a third lifting device. Finally, the bottom formwork is transported to the concrete pile manufacturing area for concrete pile manufacturing. Specific manufacturing procedures can refer to existing technologies.

[0034] The entire production line operates smoothly and efficiently, making automated production of centrifugal concrete piles possible. Furthermore, the production capacity of each process at each work site is relatively balanced, thus establishing a sound framework for the automation and intelligentization of the entire production line.

[0035] As shown in the figure, this is the second preferred embodiment of the present invention.

[0036] The difference between this embodiment and the first embodiment is that it also includes a pile exit channel 7 that can transport the concrete piles towards the steam curing zone D. This pile exit channel 7 is adjacent to the pile demolition zone C and the steam curing zone D.

[0037] The working process is different from the first embodiment except that the direction of pile exit is different. When exiting the pile, the first lifting and hoisting equipment 8 is used to lift the pile from the pile area C and transport it to the pile exit channel 7, and then transport it to the left side through the pile exit channel 7.

[0038] It should be noted that in the description of this embodiment, the terms "front," "rear," "left," "right," "inner," "outer," "upper," and "lower," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are merely for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
