Description

Technical Field

[0001] The present invention relates to the technical field of precast concrete piles, and in particular to a production system for producing precast concrete components. The present invention also relates to a method for producing precast concrete piles. Background Art

[0002] Precast piles used in the construction field mainly include two types of precast concrete piles and steel piles. Precast concrete piles are concrete piles with steel cages inside that are prefabricated in factories. They are characterized by being able to withstand large loads, being strong and durable, and having a fast construction speed.

[0003] Precast concrete piles are mostly processed and manufactured in the ground work area of ​​the factory. The production process usually includes preparing concrete materials, preparing steel cages, placing steel cages into molds, tensioning, injecting concrete materials into molds, steam curing, demoulding, stacking, etc. Since the entire production process is carried out in a factory with limited area and space, it is particularly important to reasonably arrange and control each production process.

[0004] Moreover, once the manufacturing system is put into use, it will be very difficult and costly to change it. Therefore, the scientific and reasonable design of the concrete precast pile manufacturing system and manufacturing process is the key scientific research direction of each manufacturer when building or upgrading a factory and before formal production.

[0005] For example, CN109676783A discloses a fixed formwork prestressed concrete square pile production line and production process, which is equipped with a mixing area, a distribution area, a cage weaving area and a molding area. The mixing area is provided with a cementitious material silo and a mixing tower. The distribution area is provided with a secondary material distribution hopper, a distribution hopper and a distribution vehicle. The cage weaving area is provided with a cage weaving machine and a steel cage stacking area. The molding area is provided with a tensioning machine, a tensioning machine track and a fixed formwork. The fixed formwork is provided with a tensioning longitudinal beam and a tensioning cross beam. A plurality of steam pipes are evenly arranged at the bottom of the fixed formwork, and the steam pipes are connected to the steam main pipe.

[0006] The mold of this production line is not easy to deform, which solves the technical problems of large mold size, back and forth movement affecting product quality, large steam consumption and high cost when entering the steam curing tank for curing. However, since it uses a crane to lift the material hopper for material distribution, and the location design of each processing area is not very reasonable, it does not have a very obvious advantage in production efficiency and manufacturing cost.

[0043] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0045] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 1 A schematic diagram of the structure of a prefabricated component production system disclosed in an embodiment of the present invention; Figure 2 for Figure 1 A top view of the precast component production system shown; Figure 3 for Figure 1 The structural schematic diagram of the prefabricated component production system shown in another perspective.

[0046] In a specific embodiment, the prefabricated component production system provided by the present invention is mainly composed of a crane and a ground work area located in a production workshop. The entire production workshop is roughly rectangular in a top view, with a certain length and width, and the size can be determined according to the specific plan. Inside the production workshop, a crane for performing various lifting operations is erected in a cross-sectional manner in the overhead area, and the work area based on the ground is divided into multiple work areas. A component production unit is set up in each work area, and all component production units operate in an overall coordinated manner according to the set process to achieve orderly production of prefabricated concrete components.

[0047] Since the entire production system is composed of multiple component production units, in order to save space, the following mainly introduces one of the component production units in detail. The other component production units are generally the same in structure. There may be slight differences between the component production units, for example, the length and number of fixed mold tables may be inconsistent, etc. Such differences should not constitute an obstacle to an accurate understanding of the present invention.

[0048] As shown in the figure, each component production unit is mainly composed of main reinforcement processing equipment, cage weaving machine 1, fixed formwork platform, reinforcement cage delivery vehicle 2, concrete placing vehicle 3 and other parts.

[0049] The main reinforcement processing equipment is mainly composed of a main reinforcement straightening and cutting machine 4 and a head piercing machine 5, wherein the main reinforcement straightening and cutting machine 4 is used to cut the disc-shaped main reinforcement into fixed-length main reinforcements, and the head piercing machine 5 is used to install sleeve nuts on both ends of the straight main reinforcement by roughening after cutting.

[0050] The cage weaving machine 1 is located beside the main reinforcement processing equipment and is used to weld the main reinforcement and spiral reinforcement into a reinforcement cage with a square cross section.

[0051] The steel cage is mainly composed of main bars distributed in a rectangular array and spiral bars wrapped and welded on the periphery of the main bars. Both ends of the main bars are usually provided with piers and sleeve nuts that are reversely locked with the piers. In the process of making the steel cage, the main bars distributed in the array pass through the cage weaving machine under the action of traction, and in the process of passing through the cage weaving machine, the cage weaving machine wraps and welds the spiral bars on the periphery of the main bars.

[0052] The fixed mold platform is located at the rear side of the cage weaving machine in the longitudinal direction, and is divided into a first fixed mold platform 6 and a second fixed mold platform 7 arranged side by side in the transverse direction. An operating channel 8 corresponding to the cage weaving machine 1 in the longitudinal direction is formed between the first fixed mold platform 6 and the second fixed mold platform 7.

[0053] The first fixed mold platform 6 and the second fixed mold platform 7 are respectively provided with a tensioning longitudinal beam, a tensioning cross beam, and a component mold located inside. The tensioning cross beams at both ends are respectively provided with a tensioning mechanism including a tensioning wire rod. When the steel cage is tensioned, the tensioning longitudinal beam and the tensioning cross beam bear the tensioning force, and the component mold does not bear the tensioning force. Therefore, the component mold can be made of thinner steel. The component mold is mainly composed of a bottom mold and a plurality of U-shaped mold cavities with openings upward located above the bottom mold, and multiple components can be produced at one time. The tensioning longitudinal beam and the tensioning cross beam form a long strip space closed in the circumferential direction, and a steam pipe is provided at the bottom thereof. The steam pipe is connected to the steam main pipe, and steam can be introduced into the fixed mold platform through the steam pipe for steam curing. When steam curing is performed, a steaming cover can be set on the top of the fixed mold platform or covered with canvas to prevent steam leakage and ensure the steaming effect.

[0054] A track 9 is provided in the running channel 8 between the first fixed formwork platform 6 and the second fixed formwork platform 7. The steel cage delivery vehicle 2 can reciprocate between the receiving position and the delivery position along the track 9. A steel cage channel 10 that runs through the front and back along the longitudinal direction is provided below the concrete placing vehicle 3, so that the steel cage delivery vehicle 2 can receive the steel cage from the cage weaving machine 1 at the receiving position. The steel cage produced by the cage weaving machine 1 passes through the steel cage channel 10 and is transported to the steel cage delivery vehicle 2. After receiving the steel cage, the steel cage delivery vehicle 2 runs along the track 9 in the running channel 8 to the delivery position to further place the steel cage into the component mold of the first fixed formwork platform 6 and the second fixed formwork platform 7.

[0055] The concrete placing vehicle 3 has a vehicle box for carrying concrete materials and a feed pipe 11 located on both sides of the vehicle box and extending outward in the lateral direction. The length of the feed pipe 11 is substantially equivalent to the width of the first fixed mold platform 6 and the second fixed mold platform 7. The feed pipe 11 is provided with discharge ports corresponding to the component molds of the first fixed mold platform 6 and the second fixed mold platform 7 so as to inject the carried concrete materials into the component molds of the first fixed mold platform 6 and the second fixed mold platform 7 during the movement along the running channel.

[0056] In order to prevent the concrete material from being blocked in the delivery pipe 11, a screw conveyor may be installed in the delivery pipe 11 to deliver the concrete material by mechanical propulsion, or a concrete pump may be installed in the vehicle to deliver the concrete material by pressurization.

[0057] Furthermore, two groups of first fixed mold platforms 6 and second fixed mold platforms 7 can be arranged in the longitudinal direction, and a tensioning machine 12 is provided between the opposite ends of the two groups of first fixed mold platforms 6 and second fixed mold platforms 7. The ends of each mold cavity of the two groups of first fixed mold platforms 6 and second fixed mold platforms 7 are provided with a tensioning mechanism including a tensioning screw, so that the steel cage placed in the fixed mold platform can be tensioned by the tensioning machine 12, so that the steel cage has prestress.

[0058] In this embodiment, a total of four component production units are provided. In order to reduce the transportation distance of concrete as much as possible, a concrete mixing mechanism 13 (such as a concrete mixing plant) can be set in the middle position of one end of the four component production units. The concrete mixing mechanism 13 is provided with a transverse material conveying pipeline 14 extending to the left and right respectively, and a longitudinal material conveying pipeline 15 is connected to the transverse material conveying pipeline 14. Each longitudinal material conveying pipeline 15 is used to convey concrete materials to the corresponding concrete placing vehicle 3.

[0059] A longitudinal pile-exiting channel 16 and a pile-exiting transport vehicle 17 that can reciprocate along the pile-exiting channel 16 are provided between two adjacent component production units. The produced prefabricated concrete components are hoisted onto the pile-exiting transport vehicle 17 by a crane and transported out of the workshop along the pile-exiting channel 16 by the pile-exiting transport vehicle 17 .

[0060] Two cranes can be set up, and their operating areas cover four component production units to meet the needs of actual production. For example, one of the cranes is used to perform the task of lifting precast concrete components from the two component production units on the left for demoulding, and the other crane is used to perform the task of lifting precast concrete components from the two component production units on the right for demoulding.

[0061] Since the cage weaving machine 1, the garbage spreading machine 12, the concrete mixing mechanism 13, the crane and other equipment can be realized by using existing technologies, these equipments will not be described in detail in this article.

[0062] Please refer to Figure 4 , Figure 4 The present invention is a schematic diagram of the delivery process of a steel cage delivery vehicle when delivering a steel cage.

[0063] As shown in the figure, the steel cage delivery vehicle 2 includes a vehicle body 18, a steel cage accommodating space 19 arranged on the vehicle body, and retractable extension arms 20 arranged on both sides of the vehicle body; the extension arms 20 are multi-section telescopic structures. In different extended states, the extension arms 20 have different lengths, corresponding to different component molds in the first fixed mold platform 6 and the second fixed mold platform 7, so as to place the steel cage 26 into the corresponding component mold along the extension arms 20.

[0064] In at least one embodiment, the extension arm 20 has a downward tilt angle relative to the horizontal plane when in the extended state, so that the steel cage 26 slides along the extension arm 20 into the component molds of the first fixed mold platform 6 and the second fixed mold platform 7.

[0065] In order to transfer the steel cage 26 to the extension arm 20, a lifting platform 21 and a lifting mechanism 22 can be set in the steel cage accommodating space 19 of the vehicle body 18, wherein the lifting platform 21 is located at the bottom of the steel cage accommodating space 19 and is used to carry the steel cage 26, and the lifting mechanism 22 is arranged below the lifting platform 21 and is used to drive the lifting platform 21 to rise or fall.

[0066] A tilting mechanism is provided between the lifting platform 21 and the lifting mechanism 22. The tilting mechanism is composed of two hydraulic cylinders 23 (or cylinders) arranged symmetrically on the left and right. The lifting platform 21 is rotatably connected to the lifting mechanism 22 and can swing left and right. The two hydraulic cylinders 23 are arranged in a V shape, one end of which is hinged to the lifting platform 21, and the other end is hinged to the lifting mechanism 22. The lifting platform 21 can be driven to tilt left or right by the hydraulic cylinders 23, so that after the steel cage 26 is lifted to a certain height, the steel cage 26 can slide to the extension arm 20 under the action of its own gravity, and then slide along the extension arm 20 into the component mold of the fixed mold platform.

[0067] Of course, the steel cage can also be transferred to the extension arm 20 by other mechanisms. For example, in other embodiments, a grate plate 24 that can be lifted to the left and to the right can be installed on the lifting platform 21, and the steel cage 26 can be pushed to the extension arm 20 by the grate plate 24 (see Figure 5 ), or, rollers 25 or belts are installed on the lifting platform 21, and the rollers 25 or belts drive the steel cage 26 to move left or right respectively, thereby transferring it to the extension arm 20 (see Figure 6 ),etc.

[0068] The above embodiments are only preferred solutions of the present invention, and are not limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation methods. For example, the concrete mixing mechanism 13 is set at a position biased to one side; or the steel cage delivery vehicle 2 and the concrete placing vehicle 3 share the same set of tracks; or a common pile outlet channel 16 is set at the central position of the entire system, etc. Since there are many possible implementation methods, they will not be explained one by one here.

[0069] In addition, the technical solutions between the embodiments can be combined with each other, but it should be based on the fact that ordinary technicians in the field can implement it. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0071] Mix and prepare concrete materials according to the formula, and supply the prepared concrete materials to each concrete placing vehicle 3;

[0072] The main reinforcement processing equipment and the cage weaving machine 1 are used to make the reinforcement cage, and the made reinforcement cage is placed on the reinforcement cage delivery vehicle 2;

[0073] Control the reinforcement cage delivery vehicle 2 to run to the delivery position in the running channel 8, and put the reinforcement cage into the component mold of the first fixed mold platform 6 and the second fixed mold platform 7;

[0074] Connect the two ends of the steel cage to the tensioning mechanism respectively, and tension the steel cage along the length direction of the steel cage by the tensioning machine 12, so that the steel cage has prestress;

[0075] Control the concrete placing vehicle 3 to run in the running channel 8 along the length direction of the first fixed mold platform 6 and the second fixed mold platform 7 in the fixed mold platform, and inject concrete material into the component molds of the first fixed mold platform 6 and the second fixed mold platform 7 during the running process;

[0076] After the curing, steam is introduced into the first fixed die table 6 and the second fixed die table 7 for steam curing;

[0077] The precast concrete components in the component mold are lifted by a crane for demoulding;

[0078] The precast concrete components are transported 16 out of the pile channel to the outside of the site.
