The platform includes a workbench for placing the manifold system, a gantry frame that slides, and quick-change couplings mounted on the boom of the gantry frame for rapid replacement of disassembly and assembly tools and lifting equipment. The disassembly and assembly tools include a hydraulically controlled flat valve switching mechanism and a hydraulic high-torque wrench. The lifting equipment includes a flat valve lifting tool and a four-way balanced installation lifting tool. The platform also includes a maintenance bench for disassembling and repairing the flat valve.

[0004] A further feature of this invention is that a coarse washing chamber and a fine washing chamber are respectively provided on both sides of the workbench, and the coarse washing chamber is movable so as to be moved to the manifold system for cleaning.

[0005] A further feature of this invention is that the coarse washing chamber is retractable.

[0006] A further feature of this invention is that an L-shaped opening is provided on the fine washing chamber corresponding to the boom of the gantry frame, and an L-shaped door is installed corresponding to the opening.

[0007] A further feature of this invention is that a cleaning platform is provided inside the fine cleaning chamber, a V-shaped support block is installed on the surface of the cleaning platform, and the cleaning platform is rotatable.

[0008] A further feature of this invention is that the gantry frame is slidable.

[0009] A further feature of this invention is that a V-shaped support block is installed on the surface of the maintenance table to support and limit the movement of the flat valve.

[0010] A further feature of this invention is that a control cabinet and a tool cabinet are installed on one side of the gantry frame, which are used to control the equipment and store disassembly tools, respectively.

[0011] The beneficial effects of this utility model are as follows:

[0012] As can be seen from the above, the rough cleaning chamber in this application facilitates the cleaning of the manifold system, reduces the cleaning time for workers, disassembles the cleaned manifold system into multiple flat valves, and then lifts the disassembled flat valves onto the maintenance table via a gantry crane for repair, thereby reducing the labor intensity of workers in moving the flat valves and further improving work efficiency. Then, the repaired flat valves are lifted by the gantry crane and placed into the fine cleaning chamber with an L-shaped opening, and then placed on the V-shaped support on the cleaning table. The rotation of the fine cleaning chamber and the cleaning table allows for fine cleaning of the repaired flat valves, further reducing the cleaning time and labor intensity for workers and improving their work efficiency.

[0018] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] refer to Figures 1 to 4This utility model proposes a throttling and well-killing manifold maintenance and cleaning platform, including two rectangular workbenches 1 for placing the manifold system 6. The two workbenches 1 are arranged sequentially on a horizontal plane. A coarse washing chamber 2 is installed on one side of each workbench 1, while six maintenance platforms 5 are installed on the side of each workbench 1 away from the coarse washing chamber. The six maintenance platforms 5 are arranged in two rows, with three platforms in each row. A fine washing chamber 4 is installed on the side of each maintenance platform 5 away from the workbench 1. Multiple rollers 21 are installed at the bottom of the coarse washing chamber 2 for moving the coarse washing chamber 2.

[0020] In use, the coarse wash chamber 2 is moved to the manifold system 6. Multiple nozzles are installed inside the coarse wash chamber 2. The nozzles are set to be aimed at the manifold system 6 and used to rinse the manifold system 6 to wash away the mud and debris on the manifold system 6. This can save the manual cleaning process and reduce the working time of the staff.

[0021] The throttling and well-killing manifold maintenance and cleaning platform also includes a gantry 3 for lifting the flat valve 61 and two slide rails 32. The two slide rails are respectively set on both sides of the workbench 1. There are two gantry 3s, both of which are slidably mounted on the slide rails 32. One gantry 3 lifts the flat valve 61 disassembled from the manifold system 6 and places it on the maintenance platform 5, while the other gantry 3 puts the repaired flat valve 61 into the fine cleaning chamber 4, thereby reducing the labor intensity and working time of the staff in handling the flat valve 61. It should be noted that the boom 31 of the gantry 3 is also equipped with quick-change couplings to enable quick replacement of disassembly and assembly tools and lifting devices. The disassembly and assembly tools include a hydraulically controlled flat valve switching mechanism and a special hydraulic high-torque wrench. The lifting devices include a flat valve lifting device and a special lifting device for four-way balance installation. The hydraulically controlled flat valve switching mechanism is based on the switch turntable in the Chinese patent for a digital pressure testing device for flat valves, publication number CN121595195A.

[0022] The maintenance platform 5 is height-adjustable, meaning it is equipped with a hydraulic lifting mechanism to drive its vertical movement. Each maintenance platform 5 is fitted with a pair of V-shaped supports 9. The flat valve 61 is suspended from these supports using the gantry frame 3. The height of the maintenance platform 5 can be adjusted to suit the worker's height, ensuring it remains at an appropriate level for maintenance. The platform is also equipped with hydraulic wrenches, flat valve gate pullers, and specialized tools for disassembling the flat valve sealing rings.

[0023] The cleaning chamber 4 has an L-shaped opening facing the maintenance table 5. It should be noted that the opening is formed by notches on the side and top of the cleaning chamber 4, and the opening corresponds to the boom 31. In this way, when the boom 31 moves towards the cleaning chamber 4 with the flat valve 61, the boom 31 can send the flat valve 61 into the middle position of the cleaning chamber 4 through the opening, avoiding interference between the boom 31 and the cleaning chamber 4.

[0024] An L-shaped door 41 is installed at the opening, and the L-shaped door 41 is slidable. A cleaning table 42 is installed inside the cleaning chamber 4. The cleaning table 42 is rotatable, meaning that a drive motor is installed inside the cleaning table 42. The drive motor drives the cleaning table to rotate through gear transmission. A pair of V-shaped supports 9 are installed on the table surface of the cleaning table 42. The repaired flat plate valve 61 is lifted by the gantry 3 and placed into the cleaning chamber 4 with the L-shaped opening, and placed on the V-shaped supports 9 of the cleaning table 42. The cleaning chamber 4 and the rotating cleaning table 42 are used to clean the repaired flat plate valve 61, allowing the flat plate valve 61 to be cleaned from multiple angles. The V-shaped supports 9 support the flat plate valve 61, keeping the bottom of the flat plate valve 61 in a suspended state, which makes it easier to clean the bottom. This reduces the cleaning time and labor intensity of the workers in moving the flat plate valve, and further improves work efficiency.

[0025] A control cabinet 8 and a tool cabinet 7 are installed on one side of the gantry frame 3. The control cabinet 8 is used to control the equipment, and the tool cabinet 7 stores the tools used for disassembly. The control cabinet 8 and the tool cabinet 7 are arranged side by side to save platform space.

[0026] Working Principle: Using the gantry 3, the manifold system 6 is placed on the workbench 1. Then, the coarse wash chamber 2 is moved to cover the manifold system 6. The nozzles of the coarse wash chamber 2 are opened to clean the manifold system 6, removing dirt and debris. Then, the coarse wash chamber 2 is returned to its starting position, and the manifold system 6 is disassembled to obtain multiple flat valves 61. The disassembled flat valves 61 are lifted by the boom 31 of the gantry 3 and placed on the maintenance platform 5. The flat valves 61 are supported by V-shaped supports 9. The height of the maintenance platform 5 is adjusted to facilitate maintenance by the staff. After maintenance, the valves are then... The flat plate valve 61 is lifted by the boom 31 of the gantry 3, and then the L-shaped door 41 is slid open. The flat plate valve is then placed into the fine cleaning chamber 4 through the opening and placed on the V-shaped support block 9 on the cleaning table 42. The boom 31 of the gantry 3 is then moved out of the fine cleaning chamber 4, and the L-shaped door 41 is closed. The flat plate valve 61 after maintenance is then cleaned using the nozzles in the fine cleaning chamber 4 and the rotating cleaning table 42. The side wall of the fine cleaning chamber 4 is equipped with a fine cleaning port and a viewing window. Rubber gloves are fitted on the fine cleaning port, and the operator can put their hands into the gloves and then pick up the high-pressure water gun located in the fine cleaning chamber 4. The operator can then use the high-pressure water gun to clean the flat plate valve through the viewing window.

[0027] In summary, by setting up the coarse cleaning chamber 2, the manifold system 6 can be cleaned more easily, reducing the cleaning time for workers. The disassembled flat valve 61 is then lifted by the gantry 3 and placed on the maintenance table 5 for repair, thereby reducing the labor intensity of workers in moving the flat valve 61 and further improving work efficiency. Then, the repaired flat valve 61 is lifted by the gantry 3 and placed into the fine cleaning chamber 4 with an L-shaped opening, and then placed on the V-shaped support block 9 on the cleaning table 42. The rotation of the fine cleaning chamber 4 and the cleaning table 42 can be used to finely clean the repaired flat valve 61, thereby reducing the cleaning time and labor intensity for workers and improving their work efficiency.
