Description

Technical Field

[0001] The present invention belongs to the field of construction, and particularly relates to a precast concrete beam production line. Background Art

[0002] With the rapid development of prefabricated building technology, the demand for components such as precast concrete beams has increased rapidly. However, there are currently several problems in the production of precast concrete beams:

[0003] (1) Most factories produce in a manual way. From template processing, formwork erection, mold calibration to form removal, all are realized manually, with single-piece processing and low production efficiency.

[0004] (2) Most factories use wooden molds as templates, resulting in extremely large material waste, which does not meet the energy conservation and environmental protection requirements of "two savings and one environmental protection" in construction.

[0005] (3) Although there are also factories that use fixed molds to produce precast concrete beams, none of them can realize the production of precast beams with any modulus (i.e., width) using the same set of molds, nor can they simultaneously form precast concrete beams with different moduli on one production line;

[0006] (4) After the concrete is poured, it needs to be manually cured during the hardening process, with low curing efficiency and being not conducive to improving production efficiency;

[0007] (5) After the precast concrete beam is poured, it is vibrated manually, which also results in low efficiency and consumes a lot of manpower;

[0008] (6) After the precast concrete beam is demolded, it is necessary to manually clean the inner wall of the mold table. At the same time, it is also necessary to manually apply a release agent, with low efficiency. Summary of the Invention

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0036] Refer to Figures 1-9A precast concrete beam production line is shown. The production line is formed by sequentially connecting a number of pouring units 1. On both sides of the production line, tracks 2 are fixedly arranged. A first gantry crane 3 and a second gantry crane 4 are connected to the tracks 2. Both the first gantry crane 3 and the second gantry crane 4 include a lifting beam frame 5. The top of the lifting beam frame 5 includes two cross beams 6. A slide rail 7 is fixedly arranged on the top of the cross beam 6. A crane body 8 is slidably connected to the slide rail 7. A vibrating device 9 is connected to the crane body 8 of the first gantry crane 3. A cleaning device is connected to the crane body 8 of the second gantry crane 4. The pouring unit 1 includes a mold table. The mold table includes a bottom mold 10. A fixed mold 11 is fixedly arranged in the middle of the bottom mold 10. Side molds 12 are connected to both sides of the bottom mold 10. The side molds 12 are connected to a side mold translation device. Cavities are arranged inside both the bottom mold 10 and the fixed mold 11. A cavity is also arranged inside the side mold 12. And the cavities of the bottom mold 10 and the fixed mold 11 are communicated. Hot air devices 13 are arranged on both sides of the pouring unit 1. The bottom mold 10 is communicated with a first air inlet pipe 14 of the hot air device 13, and hot air is returned to the hot air device 13 through a first return air pipe 55. The side mold 12 is communicated with a second air inlet pipe 56 of the hot air device 13, and hot air is returned to the hot air device 13 through a second return air pipe 55.

[0037] The process of using the present invention is as follows. First, the bottom mold 10 and the fixed mold 11 of the perfusion unit 1 are set up (the number of perfusion units 1 on the production line is increased or decreased according to the length of the precast concrete beam). Subsequently, the side mold 12 is connected to the side mold translation device. Since the side mold 12 is connected to both sides of the fixed mold 11, double-station production can be achieved. After the side mold 12 is connected, the positions of the two side molds 12 are adjusted according to the modulus (i.e., width) of the concrete beam to be produced, so as to adjust the distance between the side molds 12 and the fixed mold 11. After the position of the side mold 12 is adjusted, baffles are fixed on both sides of the side mold 12 (the baffles are not shown in the figure, and their function is to prevent the concrete from flowing out from both sides). Then, concrete is injected into the mold table. After the concrete injection is completed, the vibration device 9 on the second gantry crane 4 is started, and the vibration device 9 moves downward to vibrate the concrete, so that the air in the concrete is discharged smoothly. During the vibration, the second gantry crane 4 moves along the track 2, so that the concrete in the mold table is fully vibrated. After the vibration is completed, wait for the concrete to harden. After the concrete hardens, the hot air devices 13 on both sides of the perfusion unit 1 are started. The main body of the hot air device 13 is the hot air blower 33. The hot air blower 33 is connected to the bottom mold 10 and the side mold 12 through the first air inlet pipe and the second air inlet pipe. The hot air generated by the hot air device 13 heats the bottom mold 10 and the side mold 12, so that the concrete in the mold table is heat-cured. During the heat-curing, the hot air blower of the hot air device 13 sends the hot air into the bottom mold 10, the fixed mold 11 and the side mold 12 through the first air inlet pipe 14 and the second air inlet pipe 15. Finally, the hot air with residual heat enters the hot air device 13 again through the first air return pipe 54 and the second air return pipe 55 for continuous use, so that the concrete beam is heat-cured, and the strength and performance of its hardening are enhanced. This way makes the hot air continuously circulate and return, effectively saving energy, reducing energy consumption, and greatly reducing the production cost. When the precast concrete beam of the present invention is prepared and needs to be demolded, the side mold 1 translation device drives the side mold 12 to move outwards, so that the precast concrete component is separated from the side mold 12. Finally, the precast concrete component is removed, and the mold table is cleaned by the cleaning device on the first gantry crane 3 to remove the dust and impurities on the bottom mold and the side mold 12, preparing for the next production.

[0038] Further, the side mold translation device includes a translation driving assembly and a lifting assembly. The translation driving assembly includes a swing seat 16, the swing seat 16 is fixed on the bottom mold 10, and a translation driving mechanism is hinged between the swing seats 16. The translation driving mechanism includes a translation rod 17, the end of the translation rod 17 is connected to a hinge seat 56, and the hinge seat 56 is fixed on the side mold 12. The lifting assembly includes a fixed seat 18, the fixed seat 18 is fixedly connected to the side mold 12, a lifting cylinder 19 is fixedly connected in the fixed seat 18, a roller fork 20 is connected to the cylinder rod of the lifting cylinder 19, a roller shaft 21 is fixedly connected in the roller fork 20, and a roller 22 is connected to the roller shaft 21. Specifically, when adjusting the position of the side mold 12, first start the lifting cylinder 19 of the lifting assembly. The cylinder rod of the lifting cylinder 19 extends downward. After the cylinder rod extends downward, it is supported on the bottom mold 10 by the roller 22 in the roller fork 20, and the side mold 12 is jacked up, so that a gap is formed between the bottom surface of the side mold 12 and the bottom mold 10, enabling the side mold 12 to move smoothly during translation. At the same time, the setting of the roller 22 reduces the friction when the side mold 12 translates. After the cylinder rod extends downward and jacks up the side mold 12, the translation driving mechanism on the translation driving assembly is started, and the translation driving mechanism makes the translation rod 17 move forward. Since the end of the translation rod 17 is connected to the hinge seat 56, when the translation rod 17 moves forward, the side mold 12 will be translated. When the side mold 12 is translated, the width of the precast concrete component can be adjusted. Finally, the lifting assembly resets. After the concrete component is prepared, the side mold 12 is lifted upward again through the lifting assembly, and the side mold moves outward, which is also very beneficial to solving the problem of difficult demolding caused by the adhesion of concrete to the side mold 12.

[0039] Further, the translation drive mechanism is a worm gear screw machine 23, the worm gear screw machine 23 is hingedly connected to the swing seat 16, the translation rod 17 is a screw in the worm gear screw machine 23, the end of the screw is connected to a rotary joint, and is connected to the hinge seat through the rotary joint, and a signal disk 25 is also fixed on the motor rod of the worm gear screw machine 23, and a sensor mounting plate 24 is also fixed on the worm gear screw machine 23, and a position detection sensor 26 corresponding to the signal disk 25 is fixed on the sensor mounting plate 24. Specifically, the translation drive mechanism of the present invention adopts a worm gear screw machine 23 (the worm gear screw machine 23 is a worm gear screw machine, which is a mature structure and will not be described here. It can be purchased on the market, such as a worm gear screw machine with a brand of Dongmai and a model of JWB SJB). When the motor of the worm gear screw machine 23 rotates, it can drive the screw therein to translate, and when the screw translates, the translation of the side mold 12 is achieved. In addition, in order to ensure the synchronous operation of the translation assembly and prevent the failure of one translation assembly lead screw to move, causing damage to other translation assemblies, a signal disk 25 is fixedly connected to the motor rod of the worm gear screw machine 23 of the present invention, and a position detection sensor 26 corresponding to the signal disk is fixed on the side of the worm gear screw machine 23. When the motor speed of the position detection sensor 26 on the translation assembly is not synchronized, the motor speed can be adjusted to achieve synchronization. If the synchronization adjustment fails, the operation is stopped to ensure that the motor will not be damaged. The two side molds of each infusion unit can be connected to two groups of lifting assemblies and two groups of translation assemblies respectively.

[0040] Furthermore, the side mold 12 is also fixed with a guide seat 30 and a bearing connection seat 27 fixed on the bottom mold 10, the bearing connection seat 27 is connected with an upper row of bearings 28 and a lower row of bearings 29, the seat plate 31 of the guide seat 30 is located between the upper row of bearings 28 and the lower row of bearings 29, and there is a gap between the seat plate 31 and the upper row of bearings 28 and the lower row of bearings 29. Specifically, the bearing seat is provided with an upper row of bearings 28 and a lower row of bearings 29, and the arrangement of the upper row of bearings 28 and the lower row of bearings 29 is to limit the side mold 12 when it moves up and down, and will not flip, so that the movement of the side mold 12 is more stable, and the gap between the seat plate 31 and the upper row of bearings 28 and the lower row of bearings 29 can also allow the side mold 12 to have a certain vertical movement space, which is convenient for the side mold 12 to detach from the bottom mold 10. In addition, a protective cover 57 is fixedly connected above the translation assembly. The provision of the protective cover 57 can prevent dust or other impurities from entering the translation assembly, and also prevent the operator from accidentally touching it and causing personal injury.

[0041] Furthermore, a spray pipe 32 is fixed on both sides of the fixed mold 11, and a plurality of spray holes are opened on the spray pipe 32, and the spray holes are arranged obliquely downward. Specifically, the present invention also includes a spray pipe 32, and steam is introduced into the spray pipe 32. With the cooperation of the hot air blower, the precast concrete components can also be maintained with wet heat. Specifically, when the water vapor sprayed from the spray pipe 32 contacts the surface of the concrete component, the wet air condenses and liquefies, and releases heat (heat of vaporization) during the liquefaction process. The condensed water continues to release heat during the cooling process. The released heat is conducted to the inside of the concrete to increase the temperature. Under high temperature and humidity conditions, the concrete quickly solidifies and hardens, and the strength increases, so that the various properties of the precast concrete components are better.

[0042] Furthermore, a plurality of hinge plates 34 are fixed to the side mold 12, and a retractable hinge rod 35 is hingedly connected to the hinge plate 34, and a clamping joint 36 is connected to the end of the hinge rod 35, and a locking seat 37 is fixed to the fixed mold 11, and a clamping groove 38 is provided in the locking seat. Specifically, the present invention fixes the hinge plate 34 on the side mold 12, and after the position of the side mold 12 is determined and the concrete is poured, the length of the hinge rod 35 is adjusted, and then it is turned over. Since a clamping joint 36 is connected to the end of the hinge rod, the hinge rod can be clamped into the clamping groove 38 on the locking seat 37 on the fixed mold 11 through the clamping rod connected to the clamping joint 36. After the hinge rod is clamped, the concrete beam can be further tied and fixed, and at the same time, the top of the side mold 12 can be prevented from expanding and deforming outward.

[0043] Further, the cleaning device includes a mounting frame, above which three dust suction cylinders 40 are fixedly connected. The dust suction cylinders 40 are respectively connected to a first dust suction pipe 41, a second dust suction pipe 42 and a third dust suction pipe 43 (connected through detachable hose connectors, which are not shown in the figure). The first dust suction pipe 41, the second dust suction pipe 42 and the third dust suction pipe 43 are respectively connected to a first dust suction flat nozzle 45, a second dust suction flat nozzle 46 and a third dust suction flat nozzle 47. A lifting device is fixed below the mounting frame, and a connecting skeleton 44 is connected to the lifting device. On both sides of the left part of the connecting skeleton 44, side mold 12 cleaning components are respectively connected. In the middle of the connecting skeleton 44, a bottom mold cleaning component is connected. The first dust suction flat nozzle 45 and the second dust suction flat nozzle 46 are respectively located at the rear of the side mold 12 cleaning components, and the third dust suction flat nozzle 46 is located at the rear of the bottom mold cleaning component. On the left side of the connecting skeleton, two side mold 12 water spraying components and a bottom mold water spraying component are also fixed. The bottom mold water spraying component is located between the two side mold 12 water spraying components. A release agent water tank 57 is also fixed on the top of the mounting frame. A release agent spraying pipe is fixed on the right side of the connecting skeleton, and the release agent spraying pipe is connected to the release agent water tank 57. The lifting device is a screw jack. A connecting plate 51 is fixed on the top of the connecting skeleton. The screw of the screw jack is fixedly connected to the connecting plate 51. A first guiding rod is also fixed on the top of the connecting skeleton. The first guiding rod passes through the guiding plate on the mounting frame. A supporting plate is provided in the middle of the connecting skeleton. The bottom mold cleaning component includes a driving motor fixed on the supporting plate. The driving motor is connected to a cleaning disc through a driving shaft. Disc brushes 58 are fixed around the cleaning disc. The side mold cleaning component includes two bearing seats. A roller brush 59 is rotatably connected in the two bearing seats. The roller brush is driven by a power motor. A jet pipe 61 is also installed on the right side of the connecting skeleton 44, and air holes are fixed on the jet pipe 61.The cleaning device of the present invention adopts the above structure. When in use, the cleaning device is first fixed on the first gantry crane through the mounting frame. Specifically, as shown in the figure, a number of diagonal braces 48 are fixed on the mounting frame, and a connecting plate 51 is fixed at the top of the diagonal braces 48. The connecting plate 51 is fixed to the moving crossbeam 6 in the middle of the gantry crane. When it is necessary to start the cleaning device to clean the mold table, the cleaning device is placed between the two side molds 12. Subsequently, the lifting device is started to adjust the height of the bottom mold cleaning assembly so that the disk brush 58 at the bottom thereof contacts the bottom mold. Then, the side mold cleaning assembly and the bottom mold cleaning assembly are started. The side mold cleaning assembly cleans the two side molds 12, and the bottom mold cleaning assembly cleans the bottom mold. The dust generated by the cleaning is adsorbed into the three dust collection cylinders through the first dust suction flat nozzle 45, the second dust suction flat nozzle 46 and the third dust suction flat nozzle 47. At the same time, the gantry crane drives the mold table cleaning device to move, thus completing the cleaning operation of the entire mold table. In order to prevent dust from flying when the present invention cleans the mold table, a water spraying assembly for the two side molds 12 and a water spraying assembly for the bottom mold are also fixed on the left side of the connecting skeleton 44. The water spraying operation is carried out before cleaning, which maintains the production environment of the workshop and prepares for the preparation of the next building component. A release agent water tank 57 is also fixed on the top of the mounting frame. A release agent spraying pipeline is fixed on the right side of the connecting skeleton 44. After the cleaning is completed, the first gantry crane drives the cleaning device to move, and the release agent spraying pipeline of the cleaning device starts to spray the release agent to prepare for the next production. The lifting device of the cleaning device adopts a screw jack 59, and the screw jack 59 drives the connecting skeleton 44 to move up and down to realize fine adjustment of the height of the connecting skeleton 44, so that the bottom mold cleaning assembly can contact the bottom mold to achieve the purpose of cleaning. Among them, the guide rod at the top of the connecting skeleton 44 can prevent the connecting skeleton 44 from rotating during lifting. The cleaning disk of the bottom mold cleaning assembly of the present invention is driven to rotate by a driving motor. In order to enhance the cleaning effect, a disk brush 58 is arranged outside the cleaning disk. The cleaning of the bottom mold can be realized through the rotation of the cleaning disk. The side mold of the present invention is cleaned by a rotating roller brush. Through the arrangement of the roller brush 59 and the power motor, the layout of various connecting components on the connecting skeleton 44 is more compact and reasonable. Finally, after the cleaning is completed, through the arrangement of the air jet pipeline, the water on the side mold and the bottom mold can be quickly evaporated, and the water droplets adhering to the side mold or the bottom mold can be quickly blown away, increasing their area and accelerating the evaporation speed.

A supporting cross plate 49 is fixed at the lower end of the screw rod. The vibrating rod 64 and the flexible shaft 53 pass through the supporting cross plate 49. The flexible shaft 53 is fixed on the supporting cross plate 49 through a fastening structure. The connecting frame body includes a cross frame. An inclined strut 48 is fixed on the cross frame. A horizontal connecting plate 51 is fixed at the top of the inclined strut 48. An installation plate is also fixed on the cross frame. A concrete pouring pipe 57 is fixed on the installation plate. A guide rod is also fixed on the supporting cross plate 49. The guide rod passes through a guide plate on the connecting frame body. The fastening structure includes a vertical plate 62. A clamp 52 is fixed on the vertical plate 62. A clamping ring 63 is fixed in the middle of the two legs of the clamp 52. The legs pass through the vertical plate 62 and are threadedly fastened to the vertical plate 62 through nuts. The numbers of both the vibrating motor 50 and the vibrating rod 64 are two groups. With the above structure of the vibrating device of the present invention, when in use, tracks for the gantry crane to move are arranged on both sides of the mold table first, and then concrete is poured into the mold table. After the concrete is poured, the screw rod lifting device of the mobile vibrating device is started. The screw rod of the screw rod lifting device moves downward, so that the vibrating rod 64 enters the concrete. Subsequently, the vibrating motor 50 is started. The vibrating motor 50 drives the vibrating rod 64 to start vibrating through the flexible shaft 53 (the connection between the vibrating motor 50, the flexible shaft 53 and the vibrating rod 64 is a prior art and can be purchased in the market, so it will not be elaborated here). While vibrating, the second gantry crane moves along the track, so that the vibrating rod 64 also moves while vibrating in the concrete, thus completing the vibration of the concrete. In addition, during vibration, the screw rod lifting device can continuously lift and lower, so that the supporting cross plate 49 and the vibrating rod 64 move up and down, thus fully completing the vibration of the concrete. In addition, the connecting frame body of the present invention is connected to the crane body 8, and the crane body 8 can also move on the lifting beam frame, so the vibrating rod 64 can also move, and concrete members with a wider width can also be vibrated.The connecting frame body of the present invention is connected to a horizontal connecting plate 51 through a horizontal frame and a diagonal brace 48, and finally connected to the crane body 8 through the horizontal connecting plate 51. This method enables the connecting frame body to maintain light weight while having sufficient strength. To make the use of the present invention more extensive, a concrete pouring pipe 57 is fixedly connected to the mounting plate on the horizontal frame. With this structure, when pouring concrete in the mold table, the concrete pouring pipe 57 can move along the mold table through the gantry crane, making the injection of concrete more uniform. To make the vibrating rod 64 and the supporting cross plate 49 more stable during lifting and lowering movement, guide rods are also fixed on the supporting cross plate 49 and guided through the guide plates on the connecting frame body. The vibrating rod 64 of the present invention is fixed to the supporting cross plate 49 through a flexible shaft 53. There is also a clamping flange clamped on the supporting cross plate 49 above the flexible shaft 53. A vertical plate is fixed below the supporting cross plate 49. Through two U-shaped clamps and nuts, the flexible shaft 53 passes through the U-shaped clamp 52, and then the U-shaped clamp 52 is fixed, so that the flexible shaft 53 can be fixed. At the same time, through the fixing of the flexible shaft 53, the vibrating rod 64 will not transmit vibration to the supporting cross plate 49 during vibration.
