Description

Technical Field

[0001] This utility model relates to the field of lock opening and closing mechanism technology, specifically to a hydraulic opening and closing mechanism frame for working valves in a lock water conveyance corridor. Background Technology

[0002] The lock hoist frame is mainly used to support and fix the mechanical components, transmission system, and gate connection devices of the hoist, and to provide a stable structural foundation for the lifting and lowering movement of the gate. Its core purpose is to ensure that the gate can withstand water pressure, its own weight, and opening and closing forces during the operation of the hoist, while ensuring the accuracy of the gate's movement trajectory.

[0003] The existing hoist frame is generally erected at the wellhead of the valve well in the water conveyance corridor of the lock, and is used to install the power component of the hydraulic hoist—the hydraulic cylinder. In the current design, the hydraulic cylinder is directly connected to the fixed hoist frame by fastening bolts. Although this connection method can stably connect the hydraulic cylinder to the hoist frame, when the hydraulic cylinder needs to be repaired, hoisting equipment is required to completely lift the hydraulic cylinder out of the hoist room before repairs can be carried out. This is not conducive to the regular maintenance of the hydraulic hoist and the repair of the hydraulic cylinder.

[0004] In summary, there is an urgent need for a hydraulic gate opening and closing mechanism for the working valves of a ship lock water conveyance corridor 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 hydraulic gate opener frame for the working valves of a lock water conveyance corridor, aiming to solve the problem that existing gate opener frames are only suitable for fixing hydraulic cylinders, which is inconvenient for the maintenance of hydraulic cylinders. The specific technical solution is as follows:

[0006] A hydraulic gate opener frame for a working valve in a lock water conveyance corridor includes a fixed frame, a movable frame for mounting a lifting cylinder, and a linear drive mechanism for driving the lifting cylinder to rotate and position. The movable frame is hinged to the fixed frame, and the linear drive mechanism includes a fixed end for hinged to the fixed frame and a movable end for hinged to the lifting cylinder.

[0007] Furthermore, the movable frame includes a U-shaped frame, a sealing plate, and fasteners. The U-shaped frame is hinged to the fixed frame, and the sealing plate is fixedly connected to the U-shaped frame by the fasteners. The lifting cylinder is arranged between the U-shaped frame and the sealing plate, and the sealing plate and the U-shaped frame are used to clamp and fix the lifting cylinder.

[0008] Furthermore, a first positioning hole is provided on the U-shaped frame, and a second positioning hole is provided on the sealing plate. The first positioning hole and the second positioning hole are arranged coaxially, and the first positioning hole and the second positioning hole are used for positioning and installing the lifting cylinder.

[0009] Furthermore, the linear drive mechanism is one of a hydraulic cylinder, a pneumatic cylinder, or an electric actuator.

[0010] Furthermore, the fixing frame includes a main body and two hinged arms. The main body is provided with an elongated through hole arranged along the height direction. The two hinged arms are fixedly connected to the main body, and the two hinged arms are respectively arranged on both sides of the elongated through hole. The two ends of the U-shaped frame are respectively hinged to the two hinged arms. The linear drive mechanism is arranged inside the elongated through hole, and the fixed end of the linear drive mechanism is hinged and fixed to the inner wall of the elongated through hole.

[0011] Furthermore, the fixing frame also includes embedded parts, with two sets of embedded parts. The two sets of embedded parts are used to be embedded and fixed in the wellhead of the valve well of the water conveyance corridor of the lock. The two ends of the main body are respectively detachably fixed and connected to the two sets of embedded parts.

[0012] Furthermore, the embedded parts include a connecting plate and anchor bars. The upper end of the anchor bar is fixedly connected to the connecting plate, and the lower end of the anchor bar is bent and arranged. The connecting plate is used to fix it to the main body. Multiple anchor bars are arranged, and all multiple anchor bars are fixedly connected to the connecting plate.

[0013] Furthermore, the mounting bracket also includes four lifting lugs, all of which are fixedly connected to the main body, and are respectively fixedly connected to the four corners of the main body.

[0014] Furthermore, the mounting bracket also includes a cover plate, which is mounted on the main body and covers the elongated through hole.

[0015] Furthermore, the cover plate includes a first plate, a second plate, and a third plate. The first plate covers the elongated through hole on the side away from the linear drive mechanism. The second plate and the third plate are arranged on the elongated through hole on the side close to the linear drive mechanism. The second plate is provided with a first clearance opening, and the third plate is provided with a second clearance opening. The first clearance opening and the second clearance opening are arranged to meet and form a clearance hole. The movable end of the linear drive mechanism passes through the clearance hole.

[0016] The application of the technical solution of this utility model has the following beneficial effects:

[0017] With the above structural design, when maintenance of the lifting cylinder is required, simply retracting the linear drive mechanism will rotate the movable frame and the lifting cylinder mounted on it from a vertical to a horizontal position, facilitating maintenance by the operator. When maintenance is complete, simply extending the linear drive mechanism will rotate the movable frame and the lifting cylinder from a horizontal to a vertical position, thus changing the lifting cylinder from maintenance to operation. In other words, simply driving the lifting cylinder to rotate via the linear drive mechanism facilitates maintenance without removing it from the hydraulic gate hoist frame, reducing maintenance time and eliminating the need for hoisting, thereby saving maintenance costs.

[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...

[0026] 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.

[0027] 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.

[0028] Example:

[0029] See Figures 1-5 This embodiment provides a hydraulic gate opener frame for a working valve in a lock water conveyance corridor, including a fixed frame 1, a movable frame 2 for mounting a lifting cylinder, and a linear drive mechanism 3 for driving the lifting cylinder to rotate and position. The movable frame 2 is hinged to the fixed frame 1, and the linear drive mechanism 3 includes a fixed end for hinged to the fixed frame 1 and a movable end for hinged to the lifting cylinder.

[0030] Specifically, the hydraulic gate opener frame of the working valve of the lock water conveyance corridor is installed at the wellhead of the valve well of the lock water conveyance corridor. It is mainly used for fixing and positioning the lifting cylinder so that the lifting cylinder can lift the valve normally for operation.

[0031] It should be noted that the existing hydraulic gate hoist frame is generally a fixed frame, and the lifting cylinder is fixedly installed on the gate hoist frame. When the lifting cylinder needs to be repaired, it is not convenient to carry out the repair work because the lifting cylinder is in an upright position. When a major overhaul is required, the lifting cylinder can only be completely removed and hoisted out of the gate hoist room for repair or returned to the factory for repair. Such repair methods are time-consuming and labor-intensive, and are not conducive to the repair of the cylinder.

[0032] It is understood that when maintenance of the lifting cylinder is required, the components on the drive end of the lifting cylinder are first removed, and the lifting cylinder is fully retracted upwards. The linear drive mechanism 3 then drives the lifting cylinder to rotate, changing it from a vertical to a horizontal position. At this point, the lifting cylinder is close to the ground, facilitating maintenance. After maintenance, the linear drive mechanism 3 drives the lifting cylinder back from a horizontal to a vertical position, thus completing the maintenance. Through the design of this structure, when maintenance of the lifting cylinder is required, it is only necessary to drive the lifting cylinder to rotate via the linear drive mechanism 3, changing it from a vertical to a horizontal position. This facilitates maintenance without removing the lifting cylinder from the hydraulic gate hoist frame, reducing maintenance time and eliminating the need for hoisting, thus saving maintenance costs. It is worth noting that during the rotation of the lifting cylinder, the movable frame 2 rotates relative to the fixed frame 1 along with the lifting cylinder.

[0033] In a preferred embodiment of this application, the movable frame 2 includes a U-shaped frame 21, a sealing plate 22, and fasteners 23. The U-shaped frame 21 is hinged to the fixed frame 1, and the sealing plate 22 is fixedly connected to the U-shaped frame 21 by the fasteners 23. A lifting cylinder is arranged between the U-shaped frame 21 and the sealing plate 22, and the sealing plate 22 and the U-shaped frame 21 are used to clamp and fix the lifting cylinder. Specifically, in this embodiment, the fastener 23 is a screw. In some other embodiments of this application, the fastener 23 can also be a bolt or other fastener capable of fastening the U-shaped frame 21 to the sealing plate 22.

[0034] As can be seen, through the configuration of the U-shaped frame 21 and the sealing plate 22, the lifting cylinder is confined and installed within the U-shaped frame 21 during installation, and locked in place by the sealing plate 22. The two U-shaped arms of the U-shaped frame 21 are hinged to the fixed frame 1 via hinge shafts. With this structural design, when the lifting cylinder needs to be installed, it is only necessary to place the lifting cylinder into the U-shaped frame 21 and lock it in place using the sealing plate 22 and fasteners 23 to complete the installation of the lifting cylinder. Installation and disassembly are relatively convenient, facilitating quick installation during maintenance.

[0035] Furthermore, a first positioning hole 211 is provided on the U-shaped frame 21 at the bottom of the U-shaped frame 21, and a second positioning hole 221 is provided on the sealing plate 22 at the middle of the sealing plate 22. The first positioning hole 211 and the second positioning hole 221 are arranged coaxially, and the first positioning hole 211 and the second positioning hole 221 are used for positioning and installing the lifting cylinder.

[0036] It should be noted that two connecting half-shafts are provided on the outer surface of the lifting cylinder. The two connecting half-shafts are arranged coaxially. During installation, one connecting half-shaft on the lifting cylinder is inserted into the first positioning hole 211 for fixation, and then the cover plate 15 is put on so that the second half-shaft on the lifting cylinder is inserted into the second positioning hole 221 for fixation, thereby fixing the lifting cylinder to the movable frame 2.

[0037] In a preferred embodiment of this application, the linear drive mechanism 3 is a hydraulic cylinder, with its cylinder body hinged to the fixed frame 1 and its piston rod hinged to the outer wall of the lifting cylinder. In some other embodiments of this application, the linear drive mechanism 3 may also be a pneumatic cylinder or an electric push rod.

[0038] It can be seen that when the hydraulic cylinder retracts, it changes the lifting cylinder from a vertical state to a horizontal state; when the hydraulic cylinder extends, it changes the lifting cylinder from a horizontal state to a vertical state.

[0039] Furthermore, the fixing frame 1 includes a main body 11 and two hinged arms 12. The main body 11 is provided with an elongated through hole 111 arranged along the height direction so that the piston rod of the lifting cylinder can pass through the elongated through hole 111 downwards to work. The two hinged arms 12 are detachably fixed to the top of the main body 11 by bolts, and the two hinged arms 12 are respectively arranged on both sides of the elongated through hole 111. The two hinged arms 12 are arranged opposite each other, and the two ends of the U-shaped frame 21 are respectively hinged to the two hinged arms 12. The linear drive mechanism 3 is arranged in the elongated through hole 111, and the fixed end of the linear drive mechanism 3 is hinged and fixed to the inner wall of the elongated through hole 111.

[0040] Furthermore, the fixing frame 1 also includes embedded parts 13. Two sets of embedded parts 13 are provided. The two sets of embedded parts 13 are used to be embedded and fixed in the wellhead of the valve well of the water conveyance corridor of the lock. The two ends of the main body 11 are respectively detachably fixed to the two sets of embedded parts 13.

[0041] It is understood that by setting the embedded part 13, the embedded part 13 is firmly connected to the valve well of the water conveyance corridor of the lock. Then, the main body 11 of the fixing frame 1 is fixed to the embedded part 13 by bolts or by welding. In this way, the main body 11 of the fixing frame 1 can be firmly fixed to the valve well of the water conveyance corridor of the lock, preventing accidents caused by the movement of the fixing frame 1 during the operation of the lock opening and closing machine.

[0042] Furthermore, the embedded part 13 includes a connecting plate 131 and an anchor bar 132. The upper end of the anchor bar 132 is fixedly connected to the connecting plate 131, and the lower end of the anchor bar 132 is bent. The connecting plate 131 is used to fixally connect to the main body 11. Multiple anchor bars 132 are arranged, and multiple anchor bars 132 are fixedly connected to the connecting plate 131.

[0043] It is known that the anchor bar 132 is welded and fixedly connected to the connecting plate 131. When the embedded part 13 is installed, the anchor bar 132 is inserted into the steel cage of the valve well of the lock water conveyance corridor, and the anchor bar 132 and the steel bars of the steel cage are arranged in an alternating manner. After the concrete is poured, the embedded part 13 is firmly fixedly connected to the valve well of the lock water conveyance corridor.

[0044] Furthermore, the mounting bracket 1 also includes four lifting lugs, all of which are welded and fixed to the main body 11, and are respectively fixedly connected to the four corners of the main body 11. During installation, steel wire ropes or hooks are used to hang the mounting bracket 1, facilitating its hoisting.

[0045] In a preferred embodiment, the mounting bracket 1 also includes a cover plate 15, which is mounted on the main body 11 and covers the elongated through hole 111.

[0046] It is understood that by setting the cover plate 15, the top of the elongated through hole 111 is covered to prevent operators from falling through the elongated through hole 111 and reduce the risk of personnel safety accidents.

[0047] Furthermore, the cover plate 15 includes a first plate 151, a second plate 152, and a third plate 153. The first plate 151 covers the elongated through hole 111 on the side away from the linear drive mechanism 3. The second plate 152 and the third plate 153 are arranged on the elongated through hole 111 on the side close to the linear drive mechanism 3. The second plate 152 is provided with a first clearance opening, and the third plate 153 is provided with a second clearance opening. The first clearance opening and the second clearance opening are arranged to meet and form a clearance hole 154. The movable end of the linear drive mechanism 3 passes through the clearance hole 154. The clearance hole 154 is an elongated hole so that the linear drive mechanism 3 can still extend and retract normally when the second plate 152 and the third plate 153 are in the covered state. A gap is left between the first plate 151 and the second plate 152 to allow the piston rod of the lifting cylinder to extend and retract freely.

[0048] It can be seen that the first plate 151, the second plate 152, and the third plate 153 cover the top of the elongated through hole 111 to prevent operators from falling through it. Simultaneously, the gap between the first plate 151 and the second plate 152 ensures that they do not interfere with the operation of the lifting cylinder. The clearance hole 154 allows the linear drive mechanism 3 to operate smoothly. It should be noted that the first plate 151, the second plate 152, and the third plate 153 are all detachably connected to the main body 11 by screws. When maintenance of the lifting cylinder is required, the first plate 151 is first removed, allowing the lifting cylinder to fully retract and the linear drive mechanism 3 to retract, changing the lifting cylinder from a vertical to a horizontal position. Then, the first plate 151 is reinstalled. At this point, the lifting cylinder is in a horizontal position, and the first plate 151, the second plate 152, and the third plate 153 are all in a covered state, facilitating maintenance of the lifting cylinder. After the maintenance is completed, the first plate 151 is removed, allowing the linear drive mechanism 3 to extend and drive the lifting cylinder to rotate, changing the lifting cylinder from a horizontal state to a vertical state. Then, the first plate 151 is installed and fixed, completing the maintenance work of the lifting cylinder.

[0049] 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.
