Description

Technical Field

[0001] This invention relates to the field of gate structure technology, specifically to a roller shutter gate device and its manufacturing method. Background Technology

[0002] In some installation scenarios, installation space is limited, and due to user needs, straight-panel gates cannot be used. Roller shutter gates designed for this purpose can reduce space requirements by using multiple curtain sections combined into a gate panel that is bent. However, due to the special gate panel structure, the drive and guidance methods of the aforementioned roller shutter gates need to be different from those of conventional gates. Furthermore, unlike the versatility of conventional gate panels, this type of gate is more inclined to be customized according to the specific scenario. Therefore, it is crucial to standardize the design of such gates so that they can be quickly assembled and applied using existing structures after obtaining the installation dimensions for the scenario. Summary of the Invention

[0003] To address the lack of standardized structures and standardized custom design and manufacturing methods for roller shutter gates, this invention provides a roller shutter gate device and manufacturing method.

[0004] The technical solution of this invention is as follows: A roller shutter gate device includes a horizontally arranged bottom beam, with vertical side beams symmetrically arranged at both ends of the bottom beam, and a roller shutter panel is arranged between the side beams. The roller shutter panel is composed of multiple rotatably connected curtain sections, and a path guide rail is arranged between the side beams to restrict the movement trajectory of the curtain sections. The end of the path guide rail away from the bottom beam is arranged in a ring and rolled up. The roller shutter panel is connected to a drive structure fixed between the side beams and is driven by the drive structure to move along the path guide rail.

[0005] The above structure enables the driving movement of the drive gate of multiple curtain sections, thereby realizing the function of opening and closing control. Moreover, its driving method and structure are more convenient for application in confined spaces.

[0006] A method for manufacturing a roller shutter-type gate device includes the following steps: S1. Frame construction: Set up the bottom beam, and symmetrically set up side beams above both ends of the bottom beam; S2, Preset guide rail: A path guide rail is embedded on the opposite side of the side beam, with one end of the path guide rail abutting against the bottom beam and the other end extending vertically beyond the side beam and then bending and winding towards the side away from the water flow direction. S3. Roller shutter assembly: Arrange multiple curtain sections along a direction perpendicular to the length direction and rotate them together. Then connect the two ends through a tensioned drive chain. S4. Installation of roller shutter: Insert the roller shutter into the end of the guide rail away from the bottom beam; S5. Drive installation: A drive shaft is horizontally installed at the upper end of the side beam facing the direction of water flow, and a drive sprocket is fitted onto the drive shaft and meshed with the drive chain.

[0007] The above methods enable the installation and application of the gate, ensuring the controllability of the roller shutter's movement path and the normal use of the gate. Furthermore, this standardized approach allows staff to quickly understand and master the installation and design of this type of gate.

[0008] As a preferred embodiment, step S3 includes: S31. Cutting profiles: Obtain profiles and cut them with the distance between the two sides of the side beam as the reference to obtain a preset number of n curtain sections. The sum of the widths of the n-1 curtain sections is not greater than the length of the side beam, and the sum of the widths of the n curtain sections is not less than the length of the side beam. S32, Curtain section cutting: A middle cut and an end cut are set on the upper and lower sides of n-2 curtain sections respectively, and a middle cut or an end cut is set on the upper and lower sides of two curtain sections respectively. S33, Curtain section assembly: After the curtain sections are arranged through the slits, they are connected by a through-hole shaft and rotated, and guide cylinders with insertion path guide rails are symmetrically set at both ends of the through-hole shaft; S34. Drive chain installation: Install a drive chain and fix both ends to the two curtain sections located at the two ends respectively.

[0009] The length and quantity of the curtain section can be obtained directly according to the scenario. The raw materials for various specifications of gates can be made by cutting general profiles, avoiding material waste. Furthermore, the drive gate combined in this way can be freely bent and unfolded, and can have different functions in different states.

[0010] To ensure a seal, the sum of the lengths of the middle and end cuts of each individual curtain section is the same as the length of the curtain section.

[0011] In order to press the bottom beam, the curtain section with only a middle cut or end notch is provided with a pressing part on the side away from the notch. The pressing part is perpendicular to the curtain section and is provided with a connector to connect to the drive chain.

[0012] The specific structure of the above-mentioned profile is as follows: the profile includes a straight plate with a rectangular cross-section and connecting parts on both sides. The cross-section of the connecting part is a right triangle, and its right-angled side is perpendicular or parallel to the straight plate. The corners away from the straight plate are rounded, and the center of the rounded corner is concentric and coaxial with the opening through which the drive shaft passes.

[0013] To ensure adaptability after connection, the middle and end incisions are made only to remove the connecting portion.

[0014] The connection with the path guide rail is achieved by having the guide cylinder coaxial with the drive shaft and having the same fillet radius as the connecting part. The length of the guide cylinder is the same as the depth of the path guide rail, and the guide cylinder is in close contact with the connecting part.

[0015] The sealing is achieved by providing a vertical sealing strip on one side of the guide rail on the side beam, and the sealing strip is in close contact with the roller shutter plate in the vertical direction.

[0016] As a preferred embodiment, a baffle is provided above the side beam on the winding section of the path guide rail.

[0017] The beneficial effects of this invention are as follows: This invention provides a roller shutter gate device and manufacturing method. Addressing the problems of existing roller shutter gate structures that use curtain sections to form roller shutter panels and switch between flat and rolled states to control water flow, this invention proposes a practical and universal standard design scheme. For this type of low-demand product, a universal design approach is adopted, designing a fixed-specification profile structure and cutting the curtain sections according to site conditions. This eliminates the limitation to fixed specifications and fixed scenarios, enabling the manufacture of roller shutter panels of various specifications and structures in different application scenarios, based on actual site requirements, and combining them with a frame structure to control water flow.

[0020] Example like Figure 4 The illustrated roller shutter gate device includes a horizontally arranged bottom beam 5 fixed to the mounting plane, with vertical side beams 6 symmetrically arranged at both ends of the bottom beam 5 for support. Guide rails can also be installed on the side beams 6 for path guidance. Based on this structure, a roller shutter panel is installed between the side beams 6. The roller shutter panel, due to its bendable and rollable characteristics, can be stored in different ways, thus achieving different driving and opening / closing methods compared to existing gates by presenting different states when the gate is open or closed. Based on this method, it can be used in scenarios with limited installation space. Specifically, the roller shutter is composed of multiple rotatably connected curtain sections 1. Adjacent curtain sections 1 can rotate, thereby changing the shutter's state and adjusting its open state for temporary storage in smaller spaces. To ensure control of water flow during opening and closing, path guides 9 are provided between the side beams 6 to restrict the movement trajectory of the curtain sections 1. These restrictions ensure precise control of each curtain section 1. During movement, the state of the roller shutter changes due to the guidance of the path guides 9. The end of the path guide 9 furthest from the bottom beam 5 is arranged in a ring-like spiral. After spiraling, as... Figure 3 As shown, its state will change, and it will not be in a straight plate shape, thus not occupying much of the upper space. Furthermore, the roller shutter is connected to the drive structure fixed between the side beams 6 and is driven by it to move along the path guide rail 9. In this way, the drive structure can ensure the driving effect regardless of the state of the roller shutter.

[0021] Based on this, the above structure enables the driving movement of the drive gate of multiple curtain sections 1, thereby realizing the function of opening and closing control level. Moreover, its driving method and structure are more convenient to use in limited spaces. In some scenarios, it can replace the conventional straight gate structure and does not require two driving methods. Instead, it can support the driving of two states of the gate through one driving method.

[0022] Because the aforementioned limitations are uncertain, and the structure of roller shutter gates is also unique, they cannot be promoted through the production of general-purpose models. Instead, they are more suited to customized production based on specific scenarios. Therefore, it is necessary to consider the cost of profiles and to complete the production of gates of various specifications in a standardized manner. To this end, the inventors have also proposed a method for manufacturing a roller shutter gate device, including the following steps: S1. Frame construction: Set the bottom beam 5, and set the side beams 6 symmetrically above both ends of the bottom beam 5. For sealing purposes, the bottom beam 5 also needs to be fitted with a sealing gasket 51 on its upper surface to cooperate with the roller shutter to achieve a bottom seal.

[0023] S2. Pre-set guide rail: A path guide rail 9 is embedded on the opposite side of the side beam 6, with one end of the path guide rail 9 abutting against the bottom beam 5, and the other end extending vertically beyond the side beam 6 before bending and rolling away from the direction of water flow. The vertically positioned path guide rail 9, after the roller shutter is installed, guides multiple curtain sections 1 vertically, arranging them in a vertical position to act as a shutter for water blocking. The upper winding and bending setting is as follows... Figure 3 As shown, it can accommodate the bent gate, and multiple curtain sections 1 are bent with adjacent curtain sections 1 to reduce the space occupied above. In contrast, it can save space above and accommodate the gate from one side, and cope with the lack of space above by using the horizontal space.

[0024] S3. Roller shutter assembly: Arrange and rotate multiple curtain sections 1 along a direction perpendicular to the length direction, then connect the two ends through a tensioned drive chain 4. The drive chain 4 is used to drive the roller shutter in any state. The specific assembly process of the curtain sections 1 is as follows: Step S3 includes: S31. Cutting Profiles: Obtaining profiles, and as follows Figure 5 , 7 As shown, the specific structure of the above-mentioned profile is as follows: the profile includes a straight plate portion 11 with a rectangular cross-section and connecting portions 12 provided on both sides. The cross-section of the connecting portion 12 is a right-angled triangle, and its right-angled side is perpendicular or parallel to the straight plate portion 11. The corners away from the straight plate portion 11 are rounded, and the center of the rounded corner is concentric and coaxial with the opening through which the drive shaft passes, i.e., as shown... Figure 5As shown, this method ensures that during the rotation and assembly of the two curtain sections 1, the ends of the two curtain sections 1 remain in contact even after rotation to a certain state. This contact ensures the water-blocking effect. Furthermore, the use of the aforementioned fixed-specification profile allows for the cutting and use of various structural types within any product design, avoiding material waste and the cost of re-molding. Based on this profile, curtain section 1 processing can be applied to various product specifications. Therefore, the profile is cut to a preset quantity of n curtain sections 1, using the distance between opposite sides of the side beam 6 as a reference. The sum of the widths of n-1 curtain sections 1 is not greater than the length of the side beam 6, and the sum of the widths of n curtain sections 1 is not less than the length of the side beam 6. This method allows for rapid calculation and cutting of the required number of curtain sections 1. The resulting roller shutter, after assembling the cut curtain sections 1, meets the usage requirements, providing both convenient storage and effective water blocking. Furthermore, this method of setting the quantity and specifications ensures that the installed roller shutter can move completely along the preset path after the drive structure is set, and only one drive structure is needed to switch between the two states.

[0025] S32, Curtain joint 1 cutting: as follows Figure 7 , 8 As shown, a middle cut 14 and an end cut 15 are respectively provided on the upper and lower sides of n-2 curtain sections 1. By setting this method, most of the curtain sections 1 can be cut in a preset manner, and then, as... Figure 6 As shown, a middle cutout 14 or an end cutout 15 is provided on the upper and lower sides of the two curtain sections 1, respectively, which can be used as end curtain sections 1 to cooperate with the drive structure to complete the drive of the roller shutter.

[0026] Furthermore, in the above structure, in order to ensure adaptability after connection, the middle cut 14 and the end cut 15 only cut off the connecting part 12. While ensuring the water-blocking effect, it can also ensure that the bent and wound state enters the winding path guide 9 to complete the storage.

[0027] It should be noted that, to ensure a tight seal, the sum of the lengths of the middle cut 14 and the end cut 15 of each individual curtain section 1 is the same as the length of the curtain section 1. Figure 8 As shown, the middle cut 14 is generally one-third of the total length, while the end cuts 15 occupy one-third on each side to ensure contact and seal after assembly.

[0028] S33, Curtain Joint 1 Assembly: After the curtain joints 1 are arranged through slits, they are connected by a through-and-rotation shaft 2, and guide cylinders 3 for the insertion path guide rail 9 are symmetrically set at both ends of the through-and-rotation shaft 2, such as... Figure 1 , 2 As shown, where Figure 2This indicates that the guide cylinder 3 is not fully inserted. It should be noted that in the above structure, if... Figure 1 , 2 As shown, the connection with the path guide rail 9 is achieved by having the guide cylinder 3 coaxial with the drive shaft to ensure a sealing effect when rotated to the vertical position, and having the same radius as the fillet of the connecting part 12. The length of the guide cylinder 3 is the same as the depth of the path guide rail 9, and the guide cylinder 3 is in close contact with the connecting part 12. The side sealing effect is achieved through cooperation with the path guide rail 9.

[0029] Moreover, based on the above structure, such as Figure 1 As shown, the sealing method is that the side beam 6 is provided with a vertical sealing strip 7 on one side of the guide rail. The sealing strip 7 is in close contact with the roller shutter in the vertical direction. After being in close contact, it can ensure the water blocking effect from the side direction, so as to ensure that it can be used normally as a gate.

[0030] S34. Installation of 4 drive chains: Four drive chains are installed, with each end fixed to a curtain section 1 located at one of the two ends. To press the bottom beam 5, curtain sections 1 with only a central cut 14 or an end notch have a pressing part 16 on the side away from the notch. The pressing part 16 is perpendicular to the curtain section 1 and is connected to the drive chain 4 by a connector 17. The tension of the drive chain 4 can be adjusted through the connector 17 to ensure locking during engagement with the drive sprocket. Then, the relative movement of the drive chain 4 relative to the drive sprocket 8 drives all the curtain sections 1 to move within the path guide rail 9. The drive chain 4 can be in a non-tensioned state when not vertical, and its tension needs to change with the state of the curtain sections 1. However, in the vertical state, it must be in a tensioned state to achieve synchronous movement during the driving process. As a preferred method, a baffle is provided above the side beam 6 on the winding section of the path guide rail 9 to block the path guide rail 9 from the side.

[0031] S4. Installation of roller shutter: Insert the roller shutter from the end of the guide rail 9 away from the bottom beam 5; S5. Drive installation: A drive shaft is horizontally installed at the upper end of the side beam 6 facing the direction of water flow, and the drive shaft is fitted with a drive sprocket 8 and engaged with the drive chain 4.

[0032] The above methods enable the installation and application of the gate, ensuring the controllability of the roller shutter's movement path and the normal use of the gate. Furthermore, this standardized approach allows staff to quickly understand and master the installation and design of this type of gate.

[0033] The length and quantity of curtain section 1 can be obtained directly according to the scenario. The raw materials for various specifications of gates can be made by cutting general profiles, avoiding material waste. Furthermore, the drive gate combined in this way can be freely bent and unfolded, and can have different functions in different states.
