Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock technology, specifically to a lock gate top pivot cover system. Background Technology
[0002] The top pivot of the miter gate in a lock is a key component connecting the miter gate and the lock head, and also serves as a spatial transition component between the miter gate structure and the lock head structure. To ensure convenient maintenance of the top pivot device, the lock head structure has a top pivot mounting groove at the installation location of the miter gate top pivot, and the groove is covered by a cover plate. Operators can pass over the cover plate to enter the miter gate, achieving passage connection between the top of the lock head and the miter gate working bridge.
[0003] To facilitate maintenance of the top pivot of the miter gate, the maintenance slot cover is typically made of steel, allowing for easy removal and inspection. In existing cover construction, support bases for the cover are usually pre-embedded within the gate body during pouring the gate's concrete. However, these pre-embedded supports are difficult to secure with formwork during installation, resulting in significant construction difficulty and a long construction period. Due to structural layout and operational requirements, the top pivot mounting slot is usually a hexagonal opening, with an opening on the side closest to the miter gate and an opening at the top, where a cover is installed. Limited civil engineering precision in the mounting slot for the cover results in large errors in shape and size, making it difficult to control the precision of cover fabrication and installation, ultimately leading to poor overall installation quality after the cover is installed.
[0004] In summary, there is an urgent need for a lock gate top pivot cover system to solve or at least partially solve the problems existing in the prior art. Utility Model Content
[0005] The purpose of this utility model is to provide a lock top pivot cover plate system for a miter gate, aiming to solve the problem of high precision control in the manufacturing and installation of cover plates in existing lock top pivot cover plate systems. The specific technical solution is as follows:
[0006] A top pivot cover system for a lock gate is provided for covering the opening of a pre-set mounting groove on the lock body. The system includes a cover body, a mounting base, and fasteners. The mounting base is installed at the opening of the mounting groove and has an opening on one side. A step is arranged on the mounting base, and the cover body overlaps the step to cover the mounting base. A fixing flange extends outward from the outer side of the mounting base, and a positioning flange extends inward from the inner side of the mounting base. The positioning flange bends downward on the side away from the mounting base to form a step, and the positioning flange is fixed to the opening of the mounting groove by fasteners.
[0007] Furthermore, the lock gate top pivot cover system also includes a water guide channel, which extends along the inner side of the mounting base and has both ends leading out from the opening end of the mounting base. The water guide channel is located below the fixed flange.
[0008] Furthermore, the mounting base is a hexagonal mounting base, and the cover plate body is set in a hexagonal shape.
[0009] Furthermore, the side of the cover plate body closest to the opening of the hexagonal mounting base is set in an arc shape.
[0010] Furthermore, the lock gate top pivot cover system also includes a support beam, which is arranged at the bottom of the cover body and on the side close to the mounting seat opening.
[0011] Furthermore, the support beam includes a pre-embedded seat and a crossbeam. Two pre-embedded seats are provided, and the two pre-embedded seats are respectively pre-embedded on the gate body. One end of the pre-embedded seat cantilevered outward, and the two ends of the crossbeam overlap the two pre-embedded seats respectively.
[0012] Furthermore, a groove facing the opening is provided on the outward cantilever end of the pre-embedded seat, and the crossbeam is confined in the groove.
[0013] Furthermore, the cover plate body includes a steel frame and a top plate laid on top of the steel frame, with the top plate welded to the top of the steel frame.
[0014] Furthermore, the cover plate body also includes a lifting ring, a through hole is provided on the top plate, a threaded hole is provided on the steel frame, and the smooth hole is provided in correspondence with the threaded hole. One end of the lifting ring screw passes through the top plate and is threadedly connected to the steel frame.
[0015] Furthermore, the top plate is a patterned steel plate with the patterned side facing upwards.
[0016] The application of the technical solution of this utility model has the following beneficial effects:
[0017] The mounting base is installed in the groove on the gate body, and the cover plate body is installed on the mounting base. When the cover plate body is closed on the mounting base, the lower surface of the cover plate body abuts and is supported on the positioning flange. The positioning flange supports the cover plate body, and the side wall of the mounting base limits the cover plate body to prevent horizontal movement in the horizontal direction. Finally, concrete is filled between the gate body and the mounting base to fill the gap between the gate body and the mounting base. During the construction process, the line connecting the upper surface of the cover plate body and the top surface of the gate body is used as a reference to make the height of the filled concrete on the side closest to the cover plate body level with the height of the top surface of the cover plate body, so that the cover plate body and the surface of the gate body will have a smooth transition after construction. This design allows for a smooth transition between the cover plate and the gate body surface, eliminating the need for precise control of dimensions during cover plate fabrication and reducing construction difficulty. Furthermore, it makes it easier to ensure the filled concrete surface is flush with the cover plate surface during the filling of the gap between the groove and the mounting base, resulting in a better installation connection between the cover plate and the mounting base.
[0018] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. These will be described below with reference to... Figures 1-4 The present invention will be described in further detail below. Attached Figure Description

[0025] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0027] Example:
[0028] See Figures 1-4This embodiment provides a top pivot cover system for a ship lock miter gate, used to cover the opening of a pre-set mounting groove on the lock body 6. It includes a cover body 1, a mounting base 2, and fasteners 3. The mounting base 2 is installed at the opening of the mounting groove, and one side of the mounting base 2 is open. A step is arranged on the mounting base 2, and the cover body 1 overlaps the step to cover the mounting base 2. A fixing flange 21 extends outward from the outer side of the mounting base 2, and a positioning flange 22 extends inward from the inner side of the mounting base 2. The positioning flange 22 is bent downward on the side away from the mounting base 2 to form a step, and the positioning flange 22 is fixed to the opening of the mounting groove by fasteners 3.
[0029] It should be noted that during the construction of gate body 6, when pouring the concrete for gate body 6, a large groove is pre-reserved at the opening of the mounting slot on the top of gate body 6 so that the mounting base 2 can be completely placed in the groove. After the main body of gate body 6 has cured, the mounting base 2 is then installed in the groove. Specifically, the fastener 3 is an expansion screw. A vertical fixing hole is drilled on gate body 6, and the expansion screw is inserted into the fixing hole to fix it to gate body 6. Then, the mounting base 2 is installed in the groove on gate body 6 using the expansion screw. It should be noted that the fixing flange 21 has a through hole, and the expansion screw passes through the through hole. When installing the expansion screw, it is necessary to drill a hole corresponding to the position of the through hole on the fixing flange 21 to prevent the fixing flange 21 from being unable to install the expansion screw after the expansion screw is installed. Next, the cover plate body 1 is installed on the mounting base 2. When the cover plate body 1 is closed on the mounting base 2, the lower surface of the cover plate body 1 abuts against and is supported on the positioning flange 22. The positioning flange 22 supports the cover plate body 1, and the side wall of the mounting base 2 limits the cover plate body 1 to prevent the cover plate body 1 from moving horizontally in the horizontal direction. Finally, concrete is filled between the gate body 6 and the mounting base 2. The concrete fills the gap between the gate body 6 and the mounting base 2. During the construction process, the line connecting the upper surface of the cover plate body 1 and the top surface of the gate body 6 is used as a reference. The height of the filled concrete on the side close to the cover plate body 1 is level with the height of the top surface of the cover plate body 1, so that the surface of the cover plate body 1 and the gate body 6 will transition smoothly after construction. This design allows the cover plate body 1 to smoothly transition with the surface of the gate body 6, eliminating the need for precise control of each dimension during cover plate processing and reducing construction difficulty. It also makes it easier to ensure that the filled concrete surface is flush with the surface of the cover plate body 1 during the filling process between the groove and the mounting base 2, resulting in a better installation connection between the cover plate body 1 and the mounting base 2.
[0030] Furthermore, the lock gate top pivot cover system also includes a water guide channel 4, which extends along the inner side of the mounting base 2, and both ends of the water guide channel 4 are led out from the open end of the mounting base 2. The water guide channel 4 is arranged below the fixed flange 21.
[0031] Specifically, the water guide channel 4 is made of channel steel with its opening facing upwards. The edge of the fixing flange 21 corresponds to the middle of the channel steel, so that rainwater flowing down from the fixing flange 21 can completely fall into the water guide channel 4 for collection. Both ends of the water guide channel 4 extend from the opening of the mounting base 2, allowing the water collected in the water guide channel 4 to be discharged smoothly. In fact, both ends of the water guide channel 4 face the waterway, and the water in the water guide channel 4 is directly discharged into the navigation channel. The water guide channel 4 is directly and watertightly welded to the bottom of the mounting base 2 to prevent rainwater from flowing into the mounting groove along the wall of the mounting base. Of course, in some other embodiments of this application, the water guide channel 4 can also be watertightly welded to the inner wall of the gate body 6. It should be noted that steel components need to be pre-embedded in the inner wall of the gate body 6 to facilitate welding.
[0032] It should be noted that without the water guide channel 4, rainwater falling onto the cover plate body 1 would flow towards the perimeter of the cover plate. Because the cover plate needs to be able to open and close flexibly, a clearance fit is required between the cover plate and the mounting base 2, meaning a certain gap will remain between them, and rainwater will flow downwards along this gap. Without the water guide channel 4, rainwater would flow directly into the mounting groove on the lock body 6 along the gap, causing erosion of the lock top pivot within the mounting groove, leading to rust in the humid environment.
[0033] Furthermore, the mounting base 2 is a hexagonal mounting base 2, and the cover plate body 1 is configured in a hexagonal shape.
[0034] Specifically, the lock top pivot generally adopts a triangular tie rod structure. Because the two support mounting slots of the triangular tie rod structure are installed at an angle to each other, in order to save more space, the corresponding mounting slot is set as a hexagonal prism, and the corresponding top shape is a hexagonal surface. Therefore, the cover plate is set as a hexagonal shape to facilitate the covering of the mounting slot.
[0035] Furthermore, the side of the cover plate body 1 closest to the opening of the hexagonal mounting base 2 is configured as an inwardly recessed arc shape.
[0036] Specifically, a steel bridge is usually installed on the miter gate of the lock. Because the miter gate needs to rotate continuously, the steel bridge will also rotate with the miter gate. The original design extended the steel bridge above the cover plate body 1. The problem with this is that during the rotation of the miter gate, the part of the steel bridge that extends onto the cover plate body 1 will also rotate with the miter gate. During the rotation, the steel bridge that extends onto the cover plate body 1 may cause injury to the on-site operators.
[0037] By setting the side of the cover plate body 1 near the opening of the mounting base 2 to be an inwardly recessed arc shape, and the center of the arc shape is set coaxially with the pivot of the miter gate, while the end of the steel bridge above the miter gate near the cover plate body 1 is set to be an outwardly protruding arc shape, the two are matched to ensure that a small gap is maintained between the steel bridge on the miter gate and the cover plate body 1 during the rotation of the miter gate, preventing the gap from being too large and causing injury to the operator, thus improving the safety of use.
[0038] Furthermore, the lock gate top pivot cover system also includes a support beam 5, which is arranged at the lower part of the cover body 1 and is located on the side near the opening of the mounting seat 2.
[0039] It is known that the lower part of the cover plate body 1 is suspended on one side of the opening of the mounting base 2. If an operator walks on it, the cover plate body 1 will deform downwards due to its thinness, which may lead to a safety accident. By setting a support beam 5 on the side of the cover plate body 1 near the opening of the mounting base 2, the rigidity of the cover plate body 1 at the opening of the mounting base 2 is improved, preventing large deformation of the cover plate near the opening of the mounting base 2 and improving the stability of the cover plate body 1 during use.
[0040] Furthermore, the support beam 5 includes a pre-embedded seat 51 and a crossbeam 52. Two pre-embedded seats 51 are provided, and the two pre-embedded seats 51 are respectively pre-embedded on the gate body 6. One end of the pre-embedded seat 51 cantilevered outward, and the two ends of the crossbeam 52 are respectively connected to the two pre-embedded seats 51.
[0041] It is known that the crossbeam 52, which overlaps with the two pre-embedded seats 51, supports the cover plate body 1. Because the crossbeam 52 is connected by overlapping, when it is necessary to inspect the top pivot of the miter door in the installation slot, the cover plate body 1 can be lifted away, and the crossbeam 52 can be easily removed, making more space available for the maintenance of the top pivot of the miter door, and making the installation and maintenance of the miter door more convenient.
[0042] Furthermore, a groove facing the opening is provided on the outward cantilever end of the pre-embedded seat 51, and the crossbeam 52 is confined in the groove.
[0043] It is known that the embedded seat 51 needs to be installed before pouring concrete. During the pouring of the gate body 6 concrete, the embedded seat 51 may shift in position. Therefore, the installation accuracy of the embedded seat 51 is not high, meaning the height error between the embedded seat 51 and the cover plate body 1 is relatively large, while the thickness of the crossbeam 52 is relatively fixed. Therefore, by setting the groove, on the one hand, the movement of the crossbeam 52 along the width direction of the embedded seat 51 can be restricted; on the other hand, a shim can be placed in the groove to eliminate the height error generated during the embedding process. Of course, during the construction of the embedded part, the height between the embedded part and the cover plate body 1 should be appropriately increased to facilitate the placement of the shim and prevent the height from being too small. Even without placing a shim, the crossbeam 52 can still lift the cover plate body 1.
[0044] Furthermore, the cover plate body 1 includes a steel frame 11 and a top plate 12 laid on top of the steel frame 11, with the top plate 12 welded to the top of the steel frame 11.
[0045] It is understood that the steel frame 11 strengthens the top plate 12, improving its load-bearing capacity and resistance to deformation. Secondly, the cooperation between the steel frame 11 and the top plate 12 reduces material usage and improves material utilization while meeting load-bearing requirements, and also lowers the overall weight of the cover plate body 1, facilitating its movement. In some other embodiments of this application, the steel frame 11 can also be a steel grid structure.
[0046] Furthermore, the cover plate body 1 also includes a lifting ring 13, a through hole is provided on the top plate 12, and a threaded hole is provided on the steel frame 11. The through hole and the threaded hole are provided in correspondence. One end of the screw of the lifting ring 13 passes through the top plate 12 and is threadedly connected to the steel frame 11.
[0047] It is understood that by setting the lifting ring 13, the entire cover plate can be easily lifted when it needs to be opened, facilitating maintenance of the miter door top pivot in the mounting slot. During normal use, the lifting ring 13 can be removed, and a rubber plug can be installed in the threaded hole, with the upper surface of the rubber plug flush with the top surface of the top plate 12. This facilitates movement of operators on the top plate 12 and prevents rainwater from entering the mounting slot through the holes in the top plate 12 or the threaded holes in the steel frame 11, while also preventing rainwater from corroding the holes in the top plate 12 or the threaded holes in the steel frame 11.
[0048] Furthermore, the top plate 12 is a patterned steel plate with the patterned surface facing upwards.
[0049] It is known that the pattern on the checkered steel plate has an anti-slip function. The top plate 12 connects with the steel bridge above the miter door. Operators need to walk on the top plate 12. By using the checkered steel plate, it is possible to prevent operators from falling when walking on the top plate 12.
[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
