Description

Technical Field

[0001] This invention relates to the field of template storage technology, and in particular to a formwork stacking device for building construction. Background Technology

[0002] With the continuous progress and development of the economy, more and more high-rise buildings are being constructed in cities. In the process of building construction, formwork is one of the important tools. Formwork is a temporary support structure, made according to design requirements, so that concrete structures and components are shaped in the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the formwork and the external loads acting on it. During construction, concrete can only be poured after the formwork is set up. The purpose of formwork engineering is to ensure the quality of concrete engineering and construction safety, speed up the construction progress, and reduce project costs. Before use, formwork generally needs to be stacked in advance at the construction site for subsequent use.

[0003] In existing technologies, construction formwork is often hoisted by lifting equipment and then directly stacked on the ground without a dedicated stacking device. During stacking, if the formwork is stacked haphazardly, it is prone to instability and collapse when the stack is high. To achieve neat stacking, manual alignment of the formwork is required for each stack, resulting in low unloading and stacking efficiency and high labor intensity. Furthermore, the indistinct gaps between neatly stacked formwork make subsequent verification of the formwork quantity inconvenient. Therefore, we propose a construction formwork stacking device. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a construction formwork stacking device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a building construction template stacking device, including a base, an installation groove is provided in the base, a placement plate is slidably connected in the installation groove, a first spring is fixedly connected between the placement plate and the bottom wall of the installation groove, and an aligning device is provided on the base;

[0006] The alignment device includes four drive cavities and four sliding grooves formed within a base. A transfer block, which is hollow, is slidably connected within each sliding groove. A second spring is fixedly connected between each transfer block and the corresponding inner wall of the sliding groove. Four first tubes are fixedly connected through the base, with one end extending into a mounting groove and the other end extending into a corresponding drive cavity. A drive block is slidably and sealingly connected within each drive cavity. A second tube is fixedly connected through each drive block, and the second tube is slidably connected to the base and extends into the corresponding sliding groove. Inside the moving groove, one end of the second pipe fitting located in the sliding groove is fixedly connected to the side wall of the corresponding transfer block. A fixing block is fixedly connected to the top wall of the transfer block. The fixing block is hollow and its top and bottom walls are open structures. The mounting groove is filled with hydraulic oil. A permanent magnet is slidably connected to the fixing block. Four third pipe fittings are fixedly connected to the base. The third pipe fittings connect the corresponding drive chamber to the mounting groove. Several fourth pipe fittings are fixedly connected to the drive block and the second pipe fitting. A third solenoid valve is installed inside each of the third and fourth pipe fittings.

[0007] In the above-mentioned construction formwork stacking device, the tidying device also includes four time-delay switches. The time-delay switches are fixedly connected to the inner wall of the corresponding sliding groove. A second solenoid valve is installed in the first pipe fitting, and a first solenoid valve is installed in the second pipe fitting. The first solenoid valve and the second solenoid valve are electrically connected to the time-delay switches through wires.

[0008] In the above-mentioned construction formwork stacking device, the fixing block is slidably connected to a metal ring, the side wall of the metal ring is fixedly connected to a fixing plate, the fixing plate is slidably connected to a plurality of sliding columns, the sliding columns are jointly fixedly connected to a tidying plate, and a plurality of third springs are fixedly connected between the tidying plate and the fixing plate.

[0009] In the aforementioned construction formwork stacking device, eight vertical plates are fixedly connected to the upper surface of the base, with each pair of vertical plates forming a group. A counting mechanism is provided at one group of vertical plates. The counting mechanism includes a rotating shaft and a rotating rod, both of which are rotatably connected to the vertical plates through bearings. A first gear is interference-fitted to a section of the rotating shaft between two vertical plates, and a second gear is interference-fitted to a section of the rotating rod between two vertical plates. The second gear meshes with the first gear. A horizontal plate is fixedly connected between one group of vertical plates, and a rack is slidably connected to the horizontal plate. The rack is slidably connected to the upper surface of a metal ring and meshes with the first gear. A scale line is engraved on the side wall of one of the vertical plates, and a pointer is fixedly connected to the end of the rotating rod near the scale line.

[0010] In the aforementioned construction formwork stacking device, a pressure relief valve is installed inside the first pipe fitting.

[0011] In the aforementioned construction formwork stacking device, the number of teeth on the second gear is three times the number of teeth on the first gear.

[0012] Compared with existing technologies, the advantages of this invention are:

[0013] While the templates are stacked, the weight of the templates themselves causes the placement plate to slide downwards, which in turn causes the drive block to slide via hydraulic oil. The sliding of the drive block drives the transfer block to move via the second pipe, which in turn causes the transfer block to move the fixed block. This causes the metal ring on the transfer block to move synchronously, and the alignment plate contacts and pushes the stacked templates to adjust their position. Thus, the templates are automatically aligned each time they are stacked, ensuring that they are not easy to tip over after being stacked to a certain height. Moreover, no manual alignment is required, resulting in lower labor intensity and higher efficiency.

[0014] The template is leveled by its own weight, eliminating the need for additional energy input and making it more energy-efficient.

[0015] After leveling, the transfer block contacts the delay switch, causing the first solenoid valve to open and the second solenoid valve to close. In conjunction with the second spring, the hydraulic oil pumped into the drive chamber is pumped into the fixed block, which causes the permanent magnet to drive the metal ring to rise. That is, after each leveling is completed, the metal ring will drive the leveling plate to rise to a certain height. As the templates are stacked, the height of the leveling plate will automatically increase, which greatly improves the automation level of the device.

[0016] By using a sliding aligning plate and a third spring, the aligning mechanism can neatly stack templates of different sizes, thus making the device more widely applicable.

[0017] Since the sliding distance of the drive block is consistent each time a template is stacked, that is, the amount of hydraulic oil pumped into the drive chamber is consistent, the rising height of the metal ring is constant each time a template is stacked, which in turn makes the rising height of the rack constant. The first and second gears reduce this movement, and the pointer and scale line react to this change. This allows for automatic counting while stacking, making it easier to count the number of templates in the future. Attached Figure Description

[0025] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0026] Example: Refer to Figure 1-6 A construction formwork stacking device includes a base 1, an installation groove 2 is provided in the base 1, a placement plate 3 is slidably connected in the installation groove 2, a first spring 4 is fixedly connected between the placement plate 3 and the bottom wall of the installation groove 2, and an aligning device is provided on the base 1.

[0027] The straightening device includes four drive cavities 5 and four sliding grooves 7 formed within the base 1, such as... Figure 2As shown, the side of the drive cavity 5 closest to the mounting groove 2 is connected to the outside, thus ensuring that the sealed sliding drive block 10 can slide freely within the drive cavity 5. A transfer block 8 is slidably connected within the sliding groove 7. The transfer block 8 is a hollow structure, and a second spring 9 is fixedly connected between the transfer block 8 and the inner wall of the corresponding sliding groove 7. Four first pipe fittings 6 are fixedly connected through the base 1. One end of the first pipe fitting 6 extends through into the mounting groove 2, and the other end extends through into the corresponding drive cavity 5. The drive block 10 is slidably connected within the drive cavity 5. A second pipe 11 is fixedly connected through the base 1, and the second pipe 11 is slidably connected through the base 1 and extends into the corresponding sliding groove 7. One end of the second pipe 11 located in the sliding groove 7 is fixedly connected through the side wall of the corresponding transfer block 8. A fixing block 16 is fixedly connected through the top wall of the transfer block 8. The fixing block 16 is hollow and has an open structure on both the top and bottom walls. The mounting groove 2 is filled with hydraulic oil. A permanent magnet 17 is slidably connected inside the fixing block 16. Four third pipes 24 are fixedly connected through the base 1. The third pipes 24 connect the corresponding drive chambers. 5 is connected to the mounting slot 2. The drive block 10 and the second pipe fitting 11 are connected together by several fourth pipe fittings 25. A third solenoid valve 26 is installed inside both the third pipe fitting 24 and the fourth pipe fitting 25. The third solenoid valve 26 is a normally open solenoid valve that closes when energized and is connected to the main circuit of the device. When the device is powered off, the third solenoid valve 26 is also de-energized, allowing the template to automatically reset when removed after power failure. When the device is powered on, the third solenoid valve 26 is always in the energized and closed state, allowing the template to automatically reset while being stacked. The weight of the plate causes the placement plate 3 to slide downwards, which in turn causes the drive block 10 to slide via hydraulic oil. The sliding of the drive block drives the transfer block 6 to move via the second pipe 11, which in turn causes the transfer block to move the fixed 16 blocks. This causes the metal ring 18 on the transfer block 6 to move synchronously, and the aligning plate 21 contacts and pushes the stacked templates to adjust their positions. Thus, the templates are automatically aligned each time they are stacked, ensuring that they are not easy to tip over after being stacked to a certain height. This eliminates the need for manual alignment, resulting in lower labor intensity and higher efficiency.

[0028] It is worth mentioning that the template is leveled by its own gravity, which can be completed without the need for additional energy input, making it more energy-efficient.

[0029] The tidying device also includes four time-delay switches 13. When a time-delay switch 13 is pressed, it provides power for a certain period and then automatically de-energizes. This is existing technology. The time-delay switches 13 are fixedly connected to the inner wall of their corresponding sliding grooves 7. A second solenoid valve 15 is installed inside the first pipe fitting 6. The second solenoid valve 15 is a normally open solenoid valve that closes when energized. A first solenoid valve 12 is installed inside the second pipe fitting 11. The first solenoid valve 12 is a normally closed solenoid valve that opens when energized. Both the first solenoid valve 12 and the second solenoid valve 15 are electrically connected to the time-delay switches 13 via wires. The first solenoid valve 12, the second solenoid valve 15, and the time-delay switches 13 are connected in series via wires. When all delay switches 13 are pressed, the first solenoid valve 12 and the second solenoid valve 15 are energized for a period of time and then automatically de-energized. After the stacking is completed, the first solenoid valve 12 is opened and the second solenoid valve 15 is closed through the contact between the transfer block 4 and the delay switch 13. At this time, the hydraulic oil in the drive chamber 5 is pumped into the fixed block 16 through the transfer pipe 6, which causes the permanent magnet 17 to drive the metal ring 18 to rise, thereby increasing the height of the stacking plate 21. That is, while stacking, the stacking plate also rises automatically as the stacking height increases, which greatly improves the automation level of the device.

[0030] A metal ring 18 is slidably connected to the fixed block 16. The metal ring 18 is made of silicon steel and has a large magnetic permeability. While being subjected to the magnetic force of the permanent magnet 17, it can also shield the magnetic force of the permanent magnet 17 to a certain extent, ensuring that the magnetic force of the permanent magnet 17 is only used to drive the movement of the metal ring 18 and will not affect the external structure. A fixed plate 19 is fixedly connected to the side wall of the metal ring 18. Several sliding columns 20 are slidably connected to the fixed plate 19. The sliding columns 20 are all fixedly connected to the tidying plate 21. Several third springs 22 are fixedly connected between the tidying plate 21 and the fixed plate 19. Through the setting of the slidable tidying plate 21 and the third springs 22, the tidying mechanism can neatly stack templates of different specifications, thereby making the device more widely applicable.

[0031] Eight vertical plates 23 are fixedly connected to the upper surface of the base 1, with each pair of vertical plates 23 forming a group. A counting mechanism is installed at one group of vertical plates 23. The counting mechanism includes a rotating shaft 28 and a rotating rod 30. Both the rotating shaft 28 and the rotating rod 30 are rotatably connected to the vertical plates 23 via bearings. A first gear 29 is interference-fitted onto a section of the rotating shaft 28 between two vertical plates 23. Two first gears 29 are provided and symmetrically arranged about their corresponding third tube fittings 24. A second gear 31 is interference-fitted onto a section of the rotating rod 30 between two vertical plates 23. Two second gears 31 are provided and symmetrically arranged about their corresponding third tube fittings 24. The second gears 31 mesh with the first gears 29. A horizontal plate 231 is fixedly connected between one group of vertical plates 23. A rack 27 is slidably connected through the horizontal plate 231. Two racks 27 are also provided, corresponding to the first gears 29. The rack 27 is slidably connected to the upper surface of the metal ring 18. The first gear 29 meshes, and one of the vertical plates 23 has a scale line 33 engraved on its side wall. The end of the rotating rod 30 near the scale line 33 is fixedly connected to a pointer 32. Each time a template is stacked, after it is put down, the hydraulic oil is pumped into the drive chamber 5 through the first pipe 6, so that when the drive block 10 slides, the distance it slides is constant each time, that is, the amount of hydraulic oil pumped into the drive chamber 5 is constant. After the first solenoid valve 12 is opened, the hydraulic oil is pumped into the fixed block 16 by the elastic force of the second spring 9. Since the amount of hydraulic oil is consistent, the height of the permanent magnet 17 rising each time is also constant, that is, the height of the rack 27 rising each time is a fixed value. By meshing the first gear 29 and the second gear 31, the angle is reduced, and the rising distance is reflected by the pointer 32 and the scale line 33. This allows the templates to be automatically counted while stacking, making it easier to count the number of templates after stacking.

[0032] The first pipe fitting 6 is equipped with a pressure relief valve 14. The opening pressure of the pressure relief valve 14 is relatively small. The main purpose of setting the pressure relief valve 14 is to allow the placement plate 3 to slide down when the template is stacked, so that the hydraulic oil enters the first pipe fitting 6 synchronously, thereby ensuring that the four transfer blocks 8 move synchronously and ensuring the neatness of the template after being pushed.

[0033] The number of teeth on the second gear 31 is three times the number of teeth on the first gear 29. By using an integer multiple of the number of teeth, the second gear 31 reduces the rotation angle of the first gear 29 by an integer multiple, and then reacts, thereby reducing the small-amplitude rotation of the first gear 29. As a result, the pointer 32 and the scale line 33 can more clearly reflect the quantity.

[0034] In this invention, while the templates are stacked using a hoisting device, the weight of the templates causes the placement plate 3 to slide down. This causes the placement plate 3 to press the hydraulic oil in the mounting groove 2 into the drive chamber 5 through the first pipe 6. As the hydraulic oil is pressed into the drive chamber 5, the drive block 10 slides. The sliding of the drive block 10 drives the transfer block 6 to slide through the second pipe 11. The sliding of the transfer block 6 causes the fixing block 16 to move, so that the four fixing blocks 16 move towards the stacked templates at the same time. The movement of the fixing blocks 16 causes the fixing plate 19 on the metal ring 18 to move, so that the tidying plate 21 contacts the side of the template and tidies its position.

[0035] While the tidying plate 21 contacts the template for tidying, the transfer block 6 also contacts the delay switch 13, which triggers the delay switch 13, causing all the first solenoid valves 12 to open and all the second solenoid valves 15 to close. At this time, due to the opening of the first solenoid valves 12 and the closing of the second solenoid valves 15, the elastic force of the second spring 9 is released, thereby resetting the transfer block 6. At the same time, the hydraulic oil pumped into the drive chamber 5 enters the transfer block 6 through the second pipe 11 and then enters the fixed block 16, causing the permanent magnet 17 to rise. After the permanent magnet 17 rises, under its magnetic attraction to the metal ring 18, the metal ring 18 rises with the permanent magnet 17, thereby increasing the height of the tidying plate 21, which is convenient for tidying up the templates that are stacked higher later.

[0036] By following the steps above, the templates are continuously stacked to ensure that the stacked templates are neat and consistent. This ensures that the templates are not easy to tip over after being stacked to a certain height, and it eliminates the need for manual tidying, resulting in lower labor intensity and higher efficiency.

[0037] Meanwhile, each time a template is stacked, after it is placed down, hydraulic oil is pumped into the drive chamber 5 through the first pipe 6, so that when the drive block 10 slides, the sliding distance is constant each time, that is, the amount of hydraulic oil pumped into the drive chamber 5 is constant. After the first solenoid valve 12 is opened, hydraulic oil is pumped into the fixed block 16 by the elastic force of the second spring 9. Since the amount of hydraulic oil is consistent, the height of the permanent magnet 17 rising each time is also constant, that is, the height of the rack 27 rising each time is a constant value. Since the height of the rack 27 rising each time is a constant value, the rotation angle of the first gear 29 meshing with it is fixed each time the metal ring 18 rises. Then, the rotation angle is reduced by the second gear 31 meshing with the first gear 29. The rotation of the second gear 31 drives the pointer 32 to rotate, so that the rising distance each time is reflected by the pointer 32 and the scale line 33. That is, the rotation angle of the pointer 32 is constant each time the template is stacked, which allows for automatic counting of the templates while stacking, making it easier to count the number of templates after stacking is completed.

[0038] When it is necessary to remove the stacked templates, the device is de-energized. At this time, the first solenoid valve 12 is closed, and the second solenoid valve 15 and the third solenoid valve 26 are also de-energized and open. The templates are then removed. As the templates are removed, the weight on the placement plate 3 decreases, and under the elastic force of the first spring 4, the placement plate 3 gradually rises and resets. While rising, the hydraulic oil in the fixing block 16 is drawn back into the mounting groove 2 through the first pipe 6, the third pipe 24, and the fourth pipe 25, so that the permanent magnet 17 drives the metal ring 18 to reset together. After all the templates are removed, the placement plate 3 is completely reset. When used again, simply energize the device again to continue using it.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
