Description

Technical Field

[0001] The present invention relates to an openable drainage channel cover plate, its driving device and installation method, specifically, a driving device and an installation method for an openable drainage channel cover plate are provided. Background Art

[0002] In municipal engineering, road drainage and construction fields, the drainage channel cover plate is an important component to ensure the normal operation of the drainage system. It not only needs to have good load-bearing performance, but also needs to be convenient for maintenance and cleaning. Traditional drainage channel cover plates usually adopt a fixed design and cannot be directly opened, which brings great inconvenience to later maintenance, dredging, drainage and other work. To solve this problem, openable precast drainage channel cover plates have emerged. Through modular design, the cover plates can be opened and reset conveniently, thus improving the operability and maintainability of the drainage system in special states.

[0003] However, there are still many problems in the installation process of existing openable precast drainage channel cover plates.

[0004] Firstly, during installation, common installation methods mainly rely on manual handling or triangular hoisting. The cover plates are placed into the pre-designed slots one by one and adjusted for alignment. Since the alignment accuracy requirements between the cover plate and the slot opening are relatively high, construction workers need to repeatedly adjust, resulting in slow installation progress. Especially in large-scale projects, it is time-consuming and laborious. Particularly in deeper or narrower drainage channels, the operation space for manual handling and hoisting is limited, which not only increases the labor intensity of construction workers, but also easily causes damage to the cover plates or installation deviation due to improper operation. Summary of the Invention

[0005] To solve the above problems, the present application needs to provide an openable drainage channel cover plate, its driving device and installation method.

[0006] According to the first aspect of the present application, an openable drainage channel cover plate is provided.

One end of the support rod is in movable contact with the base, and the other end is rotatably connected to the movable block. Wherein, a plurality of through holes communicating with the hollow-out groove are provided on the movable plate. The movable block can be flipped from the receiving space around the connecting shaft to expose the hollow-out groove to change the drainage volume. The support rod swings during the flipping process to support the movable plate when the movable plate is flipped to a preset angle.

[0011] In a preferred embodiment of the present application, the first lead screw mechanism includes a first variable-speed drive, a first lead screw, and a first sliding block; the second lead screw mechanism includes a second variable-speed drive, a second lead screw, and a second sliding block; wherein, the second lead screw mechanism is connected to the first sliding block, and the first lead screw is meshed with the output end of the first variable-speed drive through a gear so as to be able to rotate under the drive of the first variable-speed drive, so that the first sliding block moves up and down along the first lead screw. The second lead screw can rotate under the drive of the second variable-speed drive, so that the second sliding block slides along the second lead screw along the first lead screw, and the movable clamping plate is connected to the second sliding block.

[0012] The lead screw lifting mechanism includes a lead screw shaft connected between the first insertion plate and the second insertion plate, two centrally symmetrically arranged third sliding blocks provided on the lead screw shaft, and a sling connected to the third sliding blocks. The openable drainage channel cover plate can be hoisted at the sling.

[0035] In order to make the above and other features and advantages of the present application clearer, the present application will be further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explaining to those skilled in the art and are merely exemplary, not restrictive.

[0036] In the following description, numerous specific details are set forth to provide a thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced without the use of these specific details. In other instances, well-known steps or operations have not been described in detail to avoid obscuring the present application.

[0037] As Figures 1 to 4 , a first aspect of the present application first provides an openable drainage channel cover plate 100, including a base 10, a movable plate 20, and a support structure 30; wherein the base 10 includes a support frame 11 extending in the length direction, a bottom plate 12, and a pivot portion 13. A hollow groove A is provided at the bottom plate 12. The support frame and the pivot portion are respectively disposed on both sides of the bottom plate 12 and protrude relative to the bottom plate 12 in the height direction to reserve a receiving space at the bottom plate. A movable block 20 is rotatably connected to the pivot portion 13 at one side thereof; the support structure 30 includes at least one support rod 31. One end of the support rod 31 is in movable contact with the base 10, and the other end is rotatably connected to the movable block 20.

[0038] Wherein, a plurality of through holes a communicating with the hollow groove A are provided on the movable plate 20. The movable block 20 can be flipped from the receiving space around the connection axis to expose the hollow groove A to change the drainage volume. The support rod 31 swings during the flipping process to support the movable plate 20 when the movable plate 20 is flipped to a preset angle.

[0039] Wherein the base 10 is fixedly installed in the drainage channel to provide structural support and a drainage channel. The movable plate 20 is opened and closed by a rotational connection to adjust the drainage volume; the support structure 30 provides mechanical support in the open state to ensure stability; the exposed area of the hollow groove of the bottom plate is controlled by the flipping angle of the movable plate; the through holes and the hollow groove form a multi-stage drainage path to reduce the risk of debris accumulation; the support rod is locked at a preset angle to prevent the movable plate from accidentally closing; the support frame 11 serves as the load-bearing skeleton of the base, extends along the length direction of the drainage channel, and disperses the load; it is located on the non-pivot side of the bottom plate 12 and forms a symmetric support with the pivot portion 13.

[0040] The hollow groove A on the bottom plate 12, with regularly arranged strip-shaped or grid-shaped shuttle-shaped holes, constitutes the main drainage channel; the receiving space is enclosed by the protruding structures of the support frame and the pivot portion and is used to accommodate the movable plate in the closed state.

[0041] The connection method of the pivot portion 13 is a hinge or a rotating shaft structure, allowing the movable plate to rotate around an axis perpendicular to the bottom plate; its connection point is the edge of the bottom plate 12, forming a lever fulcrum with the support frame.

[0042] One side edge of the movable plate 20 is fixed to the pivot portion 13 by a shaft pin; the movement trajectory is to flip within the range from 0° (closed) to 90° (fully open) to expose or cover the hollow groove A.

[0043] The through-holes a are arranged in an array on the surface of the movable plate, and the hole diameter is smaller than the size of the hollow groove A; its function is to assist in drainage: when the movable plate is closed, a small amount of drainage is achieved through the through-holes, and at the same time, the accumulation of sundries is blocked.

[0044] One end of the support rod 31 is connected: it is hinged to the inner surface of the movable plate 20 to form a rotating pair; the other end contacts the surface of the support frame 11 through a sliding groove or a clamping groove and is allowed to move along a specific path;

[0045] During the opening process: when the movable plate 20 flips, the support rod slides and swings from the initial position to form a triangular support structure; locking angle: when the movable plate flips to 90°, the end of the support rod is locked to achieve mechanical locking.

[0046] In summary, a drainer cover plate provided by the present application, through the cascaded design of the through-holes and the hollow grooves, takes into account the daily drainage and the emergency drainage requirements during heavy rain. Its modular design allows prefabrication, and it can be used alone or combined to form a specific shape, and has the ability of rapid deployment.

[0047] In a further solution of the present application, the support structure 30 further includes a limiting groove 32 in the width direction, and the limiting groove 32 is arranged at the end of the bottom plate 12; wherein, one end of the support rod 31 is embedded in the limiting groove 32 and can slide in the groove, and the width of the limiting groove 32 matches the diameter of the support rod 31; a positioning groove 33 that is recessed relative to the bottom of the limiting groove 32 and has the same width is also arranged in the limiting groove 32. When the movable plate 20 flips to 90° with the base 10, the support rod 31 falls into the positioning groove 33 and one end abuts against the inner wall of the positioning groove 33.

[0048] Specifically, the limiting groove 32 is opened at the end of the base 12 and extends in the width direction. One end of the support rod 31 is embedded in the groove and can slide along the groove. The groove width matches the diameter of the support rod 31 (tolerance ≤ ±2 mm), forming a lateral displacement constraint, and only allowing the support rod 31 to slide along the groove length direction, restricting its left and right offset.

[0049] During the flipping process of the movable plate 20, the limiting groove 32 restricts the freedom of the support rod 31 through physical boundaries, avoiding the lateral movement of the support rod 31 caused by heavy rain impact or external force, and ensuring that the support structure is always within the effective support area.

[0050] Further, the positioning groove 33 is arranged in the limiting groove 32, the groove bottom is further recessed relative to the limiting groove 32, and the width is the same as the diameter of the support rod 31; when the movable plate 20 flips to 90° (perpendicular to the base 10), the support rod 31 slides into the positioning groove 33, and its end abuts against the inner wall of the positioning groove 33 to form mechanical locking.

[0051] In this application, an embedding space for the support rod 31 is provided only at the 90° position to ensure that the movable plate 20 is accurately maintained in a vertically open state under heavy rain conditions, avoiding angle deviation caused by water flow impact; when the support rod 31 abuts against the inner wall of the positioning groove 33, the support force is converted from sliding friction to rigid contact, significantly enhancing the impact resistance of the support structure.

[0052] Among them, the pivot parts 13 are respectively located at two ends of the bottom plate 12 in the length direction to provide a turning avoidance space. The pivot parts 13 occupy the end regions of the bottom plate 12, enabling the root (near the pivot part 13 side) of the movable plate 20 to swing outward from the bottom plate 12 when the movable plate 20 flips, avoiding interference with the base 10.

[0053] As Figures 6 to 8 , in the second aspect of this application, a driving device for an openable drainage channel cover plate is further provided, which is applied to the openable drainage channel cover plate according to any one of claims 1 to 3, and includes a main body device 201, a two-axis motion device 202, and a lifting and mounting device 203.

[0054] Among them, the main body device 201 includes a main body bracket 2011 and a driving motor 2012 arranged on one side of the main body bracket 2011;

[0055] The two-axis motion device 202 includes a mounting bracket 2021, a first lead screw mechanism 2022, a second lead screw mechanism 2023, a fixed clamping plate 2024, and a movable clamping plate 2025. The first lead screw mechanism 2022 and the second lead screw mechanism 2023 are both connected to the mounting bracket 2021. The movable clamping plate 2025 is connected to the second lead screw mechanism 2023. The first lead screw mechanism 2022 is vertically arranged, the second lead screw mechanism 2023 is horizontally arranged and connected to the first lead screw mechanism 2022. The second lead screw mechanism 2023 can drive the movable clamping plate 2025 to move away from or close to the first lead screw mechanism 2022, and the first lead screw mechanism 2022 can drive the fixed clamping plate 2024 and the movable clamping plate 2025 to lift;

[0056] The lifting and mounting device 203 includes a first insertion plate 2031 and a second insertion plate 2032 arranged at intervals, and a lead screw lifting mechanism 2033 connected between the first insertion plate 2031 and the second insertion plate 2032. The first insertion plate 2031 is connected to the fixed clamping plate 2024, the second insertion plate 2032 is connected to the movable clamping plate 2025. The openable drainage channel cover plate can be hoisted on the lead screw lifting mechanism 2023. The lead screw lifting mechanism 2033 is connected to the driving motor 2012 and can lift the openable drainage channel cover plate under the driving of the driving motor 2012 under the constraint of the first insertion plate 2031 and the second insertion plate 2032.

[0057] The main body support 2011 serves as the basic support structure for the entire driving device, providing an installation platform for other components. It can be optionally made of an aluminum alloy frame, with 4 adjustable anti-vibration feet integrated at the bottom (load-bearing capacity ≥ 2 tons) to ensure the stable support of the driving device. The driving motor 2012 is arranged on one side of the main body support 2011 and is used to drive the subsequent screw lifting mechanism components to work.

[0058] The installation bracket 2021 is used to install and support other components of the two-axis motion device. The first screw mechanism 2022 is vertically arranged and is used to drive the fixed clamping plate 2024 and the movable clamping plate 2025 to perform lifting motion in the vertical direction.

[0059] The second screw mechanism 2023 is horizontally arranged and is connected to the first screw mechanism 2022. It can drive the movable clamping plate 2025 to move away from or close to the first screw mechanism 2022 in the horizontal direction.

[0060] It can be understood that the position of the fixed clamping plate 2024 is relatively fixed and is used in cooperation with the movable clamping plate 2025. The movable clamping plate 2025 is connected to the second screw mechanism 2023 and can move horizontally under the drive of the second screw mechanism 2023.

[0061] The first insertion plate 2031 and the second insertion plate 2032 are arranged at intervals and are used to constrain and position the openable drainage channel cover plate to ensure its stability during the lifting process.

[0062] The screw lifting mechanism 2033 is connected between the first insertion plate 2031 and the second insertion plate 2032 and is connected to the driving motor 2012. It can, under the drive of the driving motor 2012, make the openable drainage channel cover plate perform lifting motion under the constraint of the first insertion plate 2031 and the second insertion plate 2032, avoiding its deviation, that is, the drainage channel cover plate can be smoothly lifted or lowered, realizing rapid installation during the construction process.

[0063] Specifically, the first insertion plate 2031 and the second insertion plate 2032 play a key constraining role. They limit the drainage channel cover plate from both sides, preventing the cover plate from deviating, shaking or tilting during the lifting process, and ensuring that the cover plate always maintains a stable linear motion trajectory. This design enables the drainage channel cover plate to be accurately lifted or lowered, thus meeting the high-precision requirements for the installation position and attitude of the cover plate in the drainage channel construction.

[0064] During the construction process, the operating workers will first draw constraint lines at the preset positions. These constraint lines are the benchmarks for installation and are used to determine the installation position and direction of the drainage channel cover plate. During installation, the operating workers first align the first plug board 2031 with one of the constraint lines as the starting positioning point for installation. Then, by continuously adjusting the position of the second plug board 2032, it is aligned with the other constraint line. During the adjustment of the second plug board 2032, precise positioning adjustment is carried out on the entire driving device and the clamped drainage channel cover plate to ensure that the cover plate is completely matched with the preset installation position.

[0065] Through the smoothness of the automatic lifting of the screw rod lifting mechanism 2033, the constraint effects of the first plug board 2031 and the second plug board 2032, and the precise guidance of the constraint lines, the drainage channel cover plate can be accurately installed into the preset drainage groove (such as Figure 5 ) to ensure the accuracy and consistency of the installation position and improve the overall construction quality of the drainage channel.

[0066] The first screw rod mechanism 2022 includes a first variable speed drive motor 2022a, a first screw rod 2022b, and a first sliding block 2022c; the second screw rod mechanism 2023 includes a second variable speed drive motor 2023a, a second screw rod 2023b, and a second sliding block 2023c; wherein, the second screw rod mechanism 2023 is connected to the first sliding block 2022c, and the first screw rod 2022b is engaged with the output end of the first variable speed drive motor 2022a through gears, so that it can rotate under the drive of the first variable speed drive motor 2022a, so that the first sliding block 2022c can move up and down along the first screw rod 2022b, and the second screw rod 2023 can rotate under the drive of the second variable speed drive motor 2023a, so that the second sliding block 2023c can slide along the second screw rod 2023 along the first screw rod 2022b, and the movable clamping plate 2025 is connected to the second sliding block 2023.

[0067] The output end of the first variable speed drive motor 2022a is connected to the first screw rod 2022b through gear meshing. When the first variable speed drive motor 2022a starts and outputs power, the power is transmitted to the first screw rod 2022b through gear transmission, causing the first screw rod 2022b to start rotating. Due to the threaded mating relationship between the first sliding block 2022c and the first screw rod 2022b, the first sliding block 2022c will perform a linear up and down movement along the first screw rod 2022b, thereby realizing the position adjustment in the vertical direction.

[0068] The second lead screw mechanism 2023 is integrally connected to the first sliding block 2022c, which means that the second lead screw mechanism 2023 will move up and down together with the first sliding block 2022c. When the second variable speed drive motor 2023a is started to drive the second lead screw 2023b to rotate, the second sliding block 2023c will move linearly along the second lead screw 2023b. Since the second lead screw mechanism 2023 is connected to the first sliding block 2022c, the movement trajectory of the second sliding block 2023c is to make a horizontal linear movement along the axis direction of the first lead screw 2022b (i.e., the vertical direction); the movable clamping plate 2025 is connected to the second sliding block 2023c. Therefore, the horizontal linear movement of the second sliding block 2023c will directly drive the movable clamping plate 2025 to move horizontally, thereby realizing the action of the movable clamping plate 2025 approaching or separating from the fixed clamping plate 2024.

[0069] The lead screw lifting mechanism 2033 includes a lead screw shaft 2033a connected between the first plug board 2031 and the second plug board 2032, two third sliding blocks 2033b symmetrically arranged on the lead screw shaft 2033a, and a sling 2033c connected to the third sliding block 2033b. The drain channel cover plate that can be opened can be hoisted at the sling 2033c; the lead screw shaft 2033a and the second plug board 2032 are connected by a ball spline bearing.

[0070] Driven by the drive motor 2012, the lead screw shaft 2033a will rotate, and through screw drive, the rotational motion is converted into the linear motion of the third sliding block 2033b, thereby realizing the lifting operation of the drain channel cover plate that can be opened.

[0071] Specifically, the two third sliding blocks 2033b are symmetrically arranged on the lead screw shaft 2033a. This symmetrical arrangement helps to ensure the balance and stability during the lifting process and avoid tilting or shaking of the drain channel cover plate during the lifting process; generally, threaded holes matching the threads of the lead screw shaft 2033a are provided inside the third sliding blocks 2033b. When the lead screw shaft 2033a rotates, the third sliding blocks 2033b will move linearly along the axis direction of the lead screw shaft 2033a. As the connection points of the sling 2033c, they convert the rotational motion of the lead screw shaft 2033a into the lifting motion of the sling 2033c, and then drive the drain channel cover plate to lift.

[0072] The lead screw shaft 2033a and the second plug board 2032 are connected together by a ball spline bearing. The ball spline shaft can, while ensuring the free rotation of the lead screw shaft 2033a, bear large radial and axial loads. At the same time, the ball spline bearing allows the second plug board 2032 to move radially relative to the lead screw shaft 2033a.

[0073] The screw rod lifting mechanism 2033 further includes a driving wheel 2033d and a handheld part 2033e. The driving wheel 2033d is arranged on the side of the first plug board 2031 away from the screw rod shaft 2033a, and the handheld part 2033e is connected to the driving wheel 2033d;

[0074] Wherein, the driving wheel 2033d and the driving motor 2012 are connected by belt drive to drive the rotation of the screw rod shaft 2033a. Under rotation, the two third sliding blocks 2033b can move away from or close to each other to drive the lifting of the openable drainage channel cover plate.

[0075] The driving wheel 2033d is connected to the driving motor 2012 by a belt. Belt drive has the advantages of simple structure, stable transmission, buffering and vibration absorption, etc. It can effectively transmit the power of the driving motor 2012 to the driving wheel 2033d, and at the same time reduce the influence of vibration and impact during the transmission process on the mechanism to a certain extent; The surface of the screw rod shaft 2033a usually has a specific thread structure. The two third sliding blocks 2033b are symmetrically arranged on the screw rod shaft 2033a, and internally provided with threaded holes matching the threads of the screw rod shaft 2033a. When the screw rod shaft 2033a rotates, due to the meshing action of the threads, the third sliding blocks 2033b will move linearly along the axis direction of the screw rod shaft 2033a. According to the different rotation directions of the screw rod shaft 2033a, the two third sliding blocks 2033b will move away from or close to each other. The sling 2033c is connected to the third sliding block 2033b, and the openable drainage channel cover plate is hoisted at the sling 2033c. When the two third sliding blocks 2033b move away from each other, the distance between the slings 2033c increases, lifting the drainage channel cover plate upward; When the two third sliding blocks 2033b move closer to each other, the distance between the slings 2033c decreases, and the drainage channel cover plate gradually descends under the action of its own gravity.

[0076] In the special case where the driving motor 2012 fails or manual control of the lifting of the drainage channel cover plate is required, the operator can directly rotate the driving wheel 2033d through the handheld part 2033e, thereby controlling the movement of the third sliding block 2033b and the lifting of the drainage channel cover plate, providing an emergency means for the operation of the drainage channel cover plate, and improving the operability and reliability of the mechanism.

[0077] The screw rod lifting mechanism 2033 further includes a limit block 2033f. The limit block 2033f is connected to the screw rod shaft 2033a and is arranged on the side of the second plug board 2032 away from the third sliding block 2033b to restrict the moving stroke of the second plug board 2032. The limit block 2033f is connected to the screw rod shaft 2033a and is arranged on the side of the second plug board 2032 away from the third sliding block 2033b. Such an installation position enables the limit block 2033f to play a role when the second plug board 2032 moves to the extreme position, blocking its further movement, thereby preventing the second plug board 2032 from falling off the screw rod shaft 2033a.

[0078] As Figure 9 , based on the above, the present application further provides an installation method for an openable drainage channel cover plate, which is applied to the driving device of the openable drainage channel cover plate, including:

[0079] S1. Control the second plug board to move in the direction away from the first plug board so that the distance between the second plug board and the first plug board can accommodate the openable drainage channel cover plate.

[0080] S2. Control the first plug board and the second plug board to descend so that the first plug board and the second plug board are respectively located on both sides in the width direction or at both ends in the length direction of the openable drainage channel cover plate.

[0081] S3. Control the second plug board to move in the direction close to the first plug board to form a constraint space.

[0082] S4. Control the screw rod lifting mechanism so that the openable drainage channel cover plate rises or falls in the constraint space.

[0083] Referring to the above, it is a control process for installing an openable drainage channel cover plate to a driving device. The operator sends instructions to the driving wheel 2033d or the driving motor 2012 through the relevant control devices (such as the operation panel, remote control, etc.) of the driving device, causing the screw rod shaft 2033a to rotate, thereby driving the third sliding block 2033b to move, and finally causing the second plug board 2032 to move in the direction away from the first plug board 2031.

[0084] Ensure that the space between the first plug board 2031 and the second plug board 2032 is large enough to smoothly place the openable drainage channel cover plate between the two, and make preparations for subsequent clamping and positioning operations.

[0085] During the process of lowering the first insertion plate 2031 and the second insertion plate 2032 as a whole, the operator needs to observe the relative positions of the insertion plates and the drain channel cover plate, and place the first insertion plate 2031 and the second insertion plate 2032 on both sides or at both ends of the openable drain channel cover plate along the width direction or the length direction respectively to form a preliminary surrounding posture; then control the driving device again to make the lead screw shaft 2033a rotate to drive the third sliding block 2033b to move in the reverse direction, and further make the second insertion plate 2032 move in the direction close to the first insertion plate 2031. As the second insertion plate 2032 moves, the distance between the first insertion plate 2031 and the second insertion plate 2032 gradually decreases, forming a relatively enclosed restraint space around the drain channel cover plate, clamping the cover plate stably in the middle to prevent the cover plate from shaking or shifting during subsequent lifting and lowering processes; by operating the control device, make the driving motor 2012 drive the lead screw shaft 2033a to rotate, and the rotation of the lead screw shaft 2033a is transmitted to the openable drain channel cover plate through components such as the third sliding block 2033b and the sling 2033c to realize the lifting or lowering of the cover plate.

[0086] After the openable drain channel cover plate is installed, at the construction site, the operator pre-draws restraint lines at the preset positions. These restraint lines are important benchmarks for installation. The worker first aligns the first insertion plate 2031 with one of the restraint lines; after the positioning of the first insertion plate 2031 is completed, the worker continuously adjusts the position of the second insertion plate 2032 to align it with another restraint line. By precisely controlling the lead screw lifting mechanism 2033, make the second insertion plate 2032 move slowly until it aligns with another restraint line. This process not only positions the second insertion plate 2032 itself, but also precisely positions and adjusts the entire driving device and the clamped drain channel cover plate, ensuring that the cover plate is completely matched with the preset installation position, and improving the accuracy and quality of the installation.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
