Description

Technical Field

[0001] This utility model belongs to the field of tilting machine technology, specifically relating to a continuous tilting machine for oil fracturing valve boxes with a dual hydraulic drive composite structure. Background Technology

[0002] The oil fracturing valve box is a key piece of equipment in the fracturing operation of shale gas and shale oil extraction. It is part of the high-pressure manifold system and is mainly used to control the flow direction, pressure and flow rate of fracturing fluid to ensure the safe and efficient operation of fracturing. When the oil fracturing valve box is in use, it needs to be turned over to prevent the formation of deposits inside. It is usually turned over by a turning machine, and the existing turning machine is a device for continuously turning the oil fracturing valve box during use.

[0003] A workpiece 90° turning machine was designed based on the authorized Chinese invention patent CN202540018U. The equipment adopts a new hydraulic system to replace the original rotating cage structure, which increases the tonnage of the workpiece that can be turned and simplifies the structure.

[0004] Chinese invention patent CN116281062A designs a 180° tilting machine for railway freight car underframes. It uses hydraulic cylinders and the workpiece's own weight to tilt the car, and is equipped with a clamping device, which increases the reliability and safety of the mechanical structure and improves the tilting speed.

[0005] The two patents mentioned above increase the tonnage of the tilting machine and reduce the number of operation steps to a certain extent. However, the application scenarios of the 90° tilting machine are still relatively limited, and the mechanical structure of the 180° tilting machine is still relatively complex. Moreover, with the further development of the market, it is inconvenient to adjust the tilting of oil fracturing valve boxes of different sizes. At the same time, the easily damaged structure of the existing 180° tilting machine greatly increases the production cost of enterprises and affects the production efficiency. Therefore, this utility model proposes a continuous tilting machine for oil fracturing valve boxes with a dual hydraulic drive composite structure. Utility Model Content

Through a simple mechanical structure, the movement of the 180° flipping machine can be simplified, effectively reducing the use of vulnerable parts and improving space utilization. It is suitable for workpieces of various sizes, improving the versatility of the flipping machine body. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 6 This utility model provides a technical solution: a dual-hydraulic-driven composite structure oil fracturing valve box continuous tilting machine, including a tilting machine body 100, the tilting machine body 100 including two bases 101, a supporting horizontal plate 102 welded to one side of the top of the base 101, and the tilting machine body 100 is also provided with:

[0028] The overturning mechanism includes a drive adjustment assembly at the end of the support plate 102. A primary overturning assembly is provided at the end connection of the two sets of drive adjustment assemblies. A primary hydraulic drive assembly is provided at the bottom of the primary overturning assembly. A secondary overturning assembly is provided at the upper surface connection of the two support plates 102. A secondary hydraulic drive assembly is provided at the bottom of the secondary overturning assembly. Positioning buffer assemblies are provided at the bottom of both the primary and secondary overturning assemblies. When the overturning machine body 100 is in use, the overturning mechanism can place and overturn oil fracturing valve boxes of different sizes, effectively solving the problem of low equipment adaptability. Through simple mechanical structure cooperation, the movement mode of the 180° overturning machine can be simplified.

[0029] To facilitate the adjustment of the distance between the primary flipping teeth 1019 and the secondary flipping teeth 1021 via the drive adjustment assembly, in this embodiment, preferably, the drive adjustment assembly includes a lead screw 1013 rotatably connected to the end of the support plate 102 via a bearing. A forward and reverse motor 1018 is fixedly mounted on the end of the lead screw 1013 by bolts. A mounting seat is provided at the bottom of the forward and reverse motor 1018, and a movable support seat 1011 is provided on the outer surface of the lead screw 1013. After the forward and reverse motor 1018 is installed and driven, the two forward and reverse motors 1018 can drive the lead screw 1013 to rotate respectively, facilitating the adjustment of the distance between the primary flipping teeth 1019 and the secondary flipping teeth 1021. This facilitates the placement of oil fracturing valve boxes of different sizes and their clamping and flipping operations, preventing the oil fracturing valve box from sliding during the flipping process and reducing risks.

[0030] To facilitate the adjustment and flipping operation of the primary flipping component, in this embodiment, preferably, the primary flipping component includes a primary flipping shaft 1012 mounted at the connection of the ends of two movable support seats 1011 via bearings. The outer surface of the primary flipping shaft 1012 is welded with primary flipping teeth 1019 at equal intervals. The primary flipping shaft 1012 can rotate to drive the primary flipping teeth 1019 to flip, thus facilitating the flipping operation.

[0031] To facilitate the adjustment and rotation of the first-stage tilting gear 1019 via the first-stage hydraulic drive assembly, in this embodiment, preferably, the first-stage hydraulic drive assembly includes a hydraulic rod 1017 movably mounted on a connecting plate and a connecting shaft. A hydraulic rail 1016 is provided on one side of the base 101. Positioning holes 1015 are equidistantly opened inside the hydraulic rail 1016. A positioning rod 1014 is engaged inside the positioning hole 1015. The bottom end of the hydraulic rod 1017 and the two hydraulic rails 1016 are positioned and engaged with the positioning hole 1015 via the positioning rod 1014. The hydraulic rod 1017 can be installed by engaging the positioning rod 1014 inside the positioning hole 1015, which facilitates installation and the operation of driving the tilting gear 1019 to rotate.

[0032] In order to facilitate the support and flipping of the oil fracturing valve box through the secondary flipping assembly, in this embodiment, preferably, the secondary flipping assembly includes a fixing seat 1024 welded and fixed to the upper surface of the supporting horizontal plate 102. The connection between the two fixing seats 1024 is connected by a secondary flipping shaft 1023 that rotates through a bearing. The outer surface of the secondary flipping shaft 1023 is welded with secondary flipping teeth 1021 at equal intervals. After the secondary flipping teeth 1021 are installed, when the secondary flipping teeth 1021 are driven, the secondary flipping shaft 1023 drives the secondary flipping teeth 1021 to flip.

[0033] In order to facilitate the driving and flipping operation of the secondary flipping gear 1021 through the secondary hydraulic drive assembly, in this embodiment, preferably, the secondary hydraulic drive assembly includes a second hydraulic rod 1027 movably connected to the bottom end of the secondary flipping gear 1021 through a connecting plate and a connecting shaft. The bottom end of the second hydraulic rod 1027 is equipped with an installation ring 1026 through a connecting pin. After the second hydraulic rod 1027 is installed, the secondary flipping gear 1021 can be driven to rotate and perform the flipping operation by starting the second hydraulic rod 1027.

[0034] In order to facilitate the positioning of the primary flipping tooth 1019 and the secondary flipping tooth 1021 to a suitable position during flipping and to buffer them to prevent impact, in this embodiment, preferably, the positioning buffer assembly includes a positioning bracket 1022 welded and fixed to the top of both sides of the base 101. Damping buffers 1025 are equidistantly installed on the upper surface of the positioning bracket 1022, and the upper surface of the damping buffer 1025 contacts the bottom end of the secondary flipping tooth 1021 and the lower surface of the primary flipping tooth 1019. During flipping, the positioning bracket 1022 can position the secondary flipping tooth 1021 and the primary flipping tooth 1019 to prevent over-flipping and reduce impact when the positioning is touched, thus extending the service life of the equipment.

[0035] The lubrication mechanism includes an oil injection lubrication component disposed on the side of the drive adjustment component. When the movable support 1011 moves on the outer surface of the lead screw 1013, the lubrication mechanism injects oil into the outer surface of the lead screw 1013 for lubrication. This facilitates the lubrication process and allows the movable support 1011 to be smoothly adjusted on the outer surface of the lead screw 1013, reducing friction.

[0036] To facilitate lubrication between the lead screw 1013 and the movable support 1011 using the lubrication assembly, in this embodiment, preferably, the lubrication assembly includes an oil reservoir 103 sealed to the oil reservoir 1013 by bolts and a gasket. The top of the oil reservoir 103 has an oil inlet 1031 through which lubricating oil is stored for convenient lubrication. The movable support 1011 has an installation groove 1034 on one side of its interior, and a drainage channel is formed at the sealed connection between one side of the oil reservoir 103 and the interior of the installation groove 1034. 1035, The inner sides of the mounting groove 1034 are fixed with reinforcing mounting plates 1033 by screws. The inside of the mounting groove 1034 is tightly installed with oil-lubricating sponge 1032 by the reinforcing mounting plates 1033. The oil-lubricating sponge 1032 contacts the surface of the lead screw 1013. After oil is discharged, it is guided to the inside of the oil-lubricating sponge 1032 through the drainage channel 1035. When the lead screw 1013 is rotated and the movable support 1011 is moved, it contacts the oil-lubricating sponge 1032 and squeezes it to discharge oil for lubrication, which facilitates oil lubrication and reduces friction.

[0037] In this utility model, the forward and reverse reversible motor 1018 is a high-power direct-drive variable frequency motor that can rotate in both directions.

[0038] The working principle and usage process of this utility model: In use, the main body 100 of the rotating machine is stably placed at the position of use by directly contacting the bottom surface of the base 101. After the main body 100 of the rotating machine is placed, the mounting seat of the forward and reverse motor 1018 is fixed at the position of use by contacting the mounting surface with mounting bolts. The hydraulic rail 1016 is fixedly installed at the position of use. According to the position of use, the bottom end of the hydraulic rod 1017 is engaged with the hydraulic rail 1016 through the positioning rod 1014 and moved into the positioning hole 1015 for installation. The mounting ring 1026 is then fixed at the position of installation to install the hydraulic rod 1027.

[0039] When the main body 100 of the flipper is installed and the oil fracturing valve box is flipped, the movement of hydraulic rod 1017 drives the first-stage flipping tooth 1019 to the flipped state, and the movement of hydraulic rod 2 1027 drives the second-stage flipping tooth 1021 to the flipped state. Hydraulic rod 1017 is then disassembled, and the two forward and reverse motors 1018 are simultaneously energized, driving the two lead screws 1013 to rotate. As the lead screws 1013 rotate, the movable support 1011 moves on the outer surface of the lead screws 1013, causing the two... When the movable support 1011 moves, it drives the first-level flipping tooth 1019 to move through the first-level flipping shaft 1012, thereby adjusting the distance between the first-level flipping tooth 1019 and the second-level flipping tooth 1021, and adjusting the distance to match the size of the oil fracturing valve box. The crane smoothly places the oil fracturing valve box to be flipped on the first-level flipping tooth 1019 and the second-level flipping tooth 1021 and clamps it. The hydraulic rod 1027 is activated to rotate through the second-level flipping shaft 1023, which drives the second-level flipping tooth 1021 to flip the valve box by 90°.

[0040] Then, repeating the same operation, rotate the two lead screws 1013, which in turn move the movable support 1011, causing the first-stage flipping tooth 1019 to move, so that the first-stage flipping tooth 1019 coincides with the second-stage flipping tooth 1021. After coincidence, start the hydraulic rod 1017 to rotate through the first-stage flipping shaft 1012, causing the first-stage flipping tooth 1019 to drive the valve box to flip again by 90°. During the flipping of the first-stage flipping tooth 1019 and the second-stage flipping tooth 1021, positioning is achieved by the positioning bracket 1022. After the flipping, the first-stage flipping tooth 1019 and the second-stage flipping tooth 1021 are positioned. When tooth 1021 flips to the bottom, it contacts the damping buffer 1025 for buffering, which facilitates shock absorption and prevents impact damage. The flipped oil fracturing valve box is then removed from the first-stage flipping tooth 1019, completing the entire flipping operation process. This facilitates a 180° flip, effectively solving the problem of low equipment adaptability. Through simple mechanical structure coordination, the movement mode of the 180° flipping machine can be simplified, effectively reducing the use of vulnerable parts and improving space utilization. It is suitable for workpieces of various sizes, improving the versatility of the flipping machine body 100.

[0041] Finally, before using the main body 100 of the tilting machine, lubricating oil is injected into the oil storage box 103 through the oil inlet 1031. After the lubricating oil is injected into the oil inlet 1031, the lubricating oil inside the oil storage box 103 is guided through the drainage channel 1035 to the oil-lubricating sponge 1032 installed inside the mounting groove 1034. After the oil-lubricating sponge 1032 is immersed in lubricating oil, the lead screw 1013 is rotated to drive the movable support seat 1011 to move on the outer surface of the lead screw 1013. The movable support seat 1011 moves on the outer surface of the lead screw 1013 and contacts the oil-lubricating sponge 1032, squeezing out oil. This makes a large amount of lubricating oil adhere to the outer surface of the lead screw 1013, which is convenient for lubricating the lead screw 1013. It is less likely to cause serious friction when the lead screw 1013 is driven, and the adjustment operation is smooth. This improves the convenience of lubricating and adjusting the lead screw 1013 when the tilting machine main body 100 continuously tilts the oil fracturing valve box.
