Description

[Technical Field]

[0001] The present invention relates to oil loading and unloading technology, and particularly to an adjustable quick butting device for oil replenishment crane pipes. [Background technology]

[0002] When refueling an oil tanker, when the oil refueling crane pipe approaches the inlet, the conventional oil refueling crane pipe requires manual butting of the crane pipe joint with the inlet. After the butting is complete, the crane pipe joint must be manually operated and clamped to the inlet flange. Because many processes are completed manually, there are problems such as high labor intensity, poor safety, and low efficiency. At the same time, due to a lack of specifications and standards for the production design of oil tanker inlets, there are currently no unified specifications for the dimensions of oil tanker cars and inlet flanges. The diameter and thickness dimensions of the inlet flanges of different oil tanker cars vary greatly. Therefore, the conventional crane pipe joint cannot be properly butted with some inlets, resulting in an ineffective seal between the crane pipe joint and the inlet.

[0003] In addition, most of the current butt joint methods all use a single rubber seal, and such a seal method will cause the rubber to deteriorate and deform over time during long-term use, resulting in insufficient sealing, which will ultimately lead to oil and gas leakage problems and certain safety issues.

[0004] Therefore, there is a great need for the invention of an adjustable automatic butting device. Summary of the Invention [Problem to be solved by the invention]

[0005] The object of the present invention is to provide an adjustable quick butting device for oil replenishment crane pipes, which can solve the problem of insufficient sealing when the conventional crane pipe joint is butted against an oil tank car to replenish oil. [Means for solving the problem]

[0006] The adjustable quick butting device for oil replenishment crane pipe of the present invention comprises a sealing mechanism, a multi-jaw chuck mechanism and a driving mechanism, the sealing mechanism comprising an oil feed pipe, a threaded sleeve fitted on the oil feed pipe, an inner seal spanner ring fitted on the front end of the threaded sleeve, and an outer seal O-ring fitted on the inner seal spanner ring, wherein the pipe mouth of the oil feed pipe is formed as a conical horn mouth and is used to clamp the inlet flange, the rear end of the threaded sleeve is provided with a flat key for fixing and attaching the cover plate and the stopper disc, the outside of the stopper disc is provided with a multi-jaw chuck mechanism, the driving mechanism is attached to the oil feed pipe, its output shaft is provided with an output gear, and the outer periphery of the stopper disc is provided with teeth that mesh with the output gear. The outer wall of the oil pipe is provided with a male thread, and the inner wall of the threaded sleeve is provided with a female thread that meshes with the male thread of the oil pipe. When the drive mechanism rotates, it rotates the stopper disk and the threaded sleeve synchronously, and the stopper disk rotates to expand and contract the gripping jaws of the multi-jaw chuck mechanism to grasp and release the inlet flange. The threaded sleeve moves along the axial direction of the oil pipe through the guiding action of the screw. Furthermore, the cover plate presses the outer sealing O-ring against the inlet flange to form a first-class seal. The front end of the threaded sleeve is openwork and is used to press against the inner wall of the inner sealing spanner ring to expand the inner sealing spanner ring into the conical horn of the oil pipe, thereby pressing against the inner wall of the inlet flange to form a second-class seal.

[0007] Furthermore, the multi-jaw chuck mechanism includes a positioning disk fixedly fitted to the oil feed pipe, and a plurality of chucks attached between the stopper disk and the positioning disk and installed circumferentially around the stopper disk, A plurality of slider grooves are formed on the side of the positioning disk along the radial direction, and when the stopper disk rotates, the plurality of chucks slide along the slider grooves of the positioning disk as the stopper disk rotates, thereby realizing radial movement of the chucks.

[0008] Furthermore, the chuck includes a slider body installed in the slider groove of the positioning disk, a gripping claw attached vertically to the upper end of the slider body for clamping the inlet flange, and a gripping claw baffle attached to the end face of the gripping claw for preventing the inlet flange from falling off, and the multiple chucks can engage with each other to grasp and release the inlet flange.

[0009] Furthermore, the inside of the slider body is hollow, and two spine strips are attached to both inner walls of the hollow structure by positioning pins and springs, and a stopper locking post is installed between the two spine strips, and the spring is attached to the positioning pin and presses the spine strips, thereby locking the stopper locking post between the two spine strips, thereby realizing the self-locking function of the chuck.

[0010] Furthermore, the upper end of the stopper locking post is a cylinder that engages with the arc-shaped stopper hole in the stopper disk, and the lower end is provided with two strip-shaped locking pieces that engage with the spine strip, which is a unidirectional spine strip, and the stopper locking post is used to move the spine strip in one direction by the two strip-shaped locking pieces, thereby adaptively clamping inlet flanges of different diameters and expanding the clamping range.

[0011] Furthermore, the stopper locking posts slide into the arc-shaped stopper holes of the stopper disk, and when the stopper locking posts slide to the outermost position of the arc-shaped stopper holes, the multi-jaw chuck mechanism is in an open state, and when the stopper locking posts slide to the innermost position of the arc-shaped stopper holes, the multi-jaw chuck mechanism is in a contracted state.

[0012] Furthermore, the upper surface of the gripping claw is arc-shaped, and a groove is formed thereon, the bottom surface of the groove has a toothed structure, and two waist-shaped through-holes are formed in the groove for installing a positioning spacer and a fixing nut, the bottom surface of the positioning spacer has a toothed shape and is engaged with the toothed structure on the bottom surface of the groove of the gripping claw, and the slider body, the gripping claw and the positioning spacer are integrally connected by the screw and the fixing nut on the slider body, thereby realizing the assembly of the main structure of the chuck.

[0013] Furthermore, by adjusting the position of the positioning spacer in the groove of the gripping jaw, injection port flanges of different thicknesses can be clamped adaptively, improving the applicability of the device.

[0014] Furthermore, the underside of the gripping jaw baffle is arc-shaped and is used to match the outer contour of the injection port flange, and a countersunk hole is provided on its front end surface. The gripping jaw baffle and the gripping jaw are connected and fixed by a baffle positioning bolt. A spacer is installed at the end of the bottom surface of the gripping jaw closest to the gripping jaw baffle, and a countersunk hole is opened in the spacer to connect and fix it to the gripping jaw with the spacer positioning bolt. The installation of the gripping jaw baffle prevents the injection port flange from being pressed down and falling off during clamping, and also prevents the spacer from wearing out against the injection port flange during clamping.

[0015] Furthermore, the drive mechanism includes a lower pipe clamp and an upper pipe clamp wrapped around the oil supply pipe, a motor bracket fixedly attached to the upper pipe clamp, and a drive motor attached to the upper end of the motor bracket, and the output gear and shaft body on the output shaft of the drive motor are connected and fixed by a key, and the output gear is driven by the drive motor to rotate the entire stopper disc and threaded sleeve. [Effects of the Invention]

[0016] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0017] The present invention designs a second-grade sealing structure, which has a relatively good sealing effect. At the same time, the inner seal spanner presses against the inner wall of the inlet flange, which improves the sealing performance. At the same time, during fuel supply, the pressing action between the inner seal spanner and the inner wall of the inlet makes the butt device less likely to fall off, making it safer and more stable.

[0018] The present invention has a self-locking function in which the stopper locking post and the spine strip engage within the slider, making it possible to adaptively clamp inlet flanges of different diameters and expand the clamping range.

[0019] The present invention can be adapted to inlet flanges of different thicknesses by adjusting the relative positions of the positioning spacers and gripping jaws in the grooves, thereby improving its applicability.

[0020] In the present invention, the drive motor drives the gear, causing the stopper disc and the threaded sleeve to rotate together, thereby realizing fast clamping and sealing at the same time, and improving work efficiency. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] The technical solutions of the present invention will be described in detail below with reference to specific embodiments and drawings in the specification.

[0023] As shown in Figures 1 to 13, the adjustable quick butting device for oil replenishment crane pipe of the present invention includes a sealing mechanism 1, an oil supply pipe 11, an inner seal span ring 12, an outer seal O-ring 13, a stopper disk 14, a cover plate 15, a threaded sleeve 16, a multi-jaw chuck mechanism 2, a chuck 21, a positioning disk 22, a slider body 2101, a slider cover plate 2102, a stopper locking column 2103, and a gripping jaw 2104. , spacer 2105, gripping claw baffle 2106, spine strip 2107, positioning pin 2108, spring 2109, positioning spacer 2110, fixing nut 2111, baffle positioning bolt 2112, spacer positioning bolt 2113, drive mechanism 3, lower pipe clamp 31, upper pipe clamp 32, motor bracket 33, drive motor 34, output gear 35, and inlet flange 4.

[0024] As shown in FIG. 1, the adjustable quick butting device for oil replenishment crane pipe of the present invention includes three parts: a sealing mechanism 1, a multi-jaw chuck mechanism 2, and a driving mechanism 3.

[0025] As shown in Figures 2 and 3, the sealing mechanism 1 includes an oil supply pipe 11, an inner seal spanner ring 12, an outer seal O-ring 13, a stopper disk 14, a cover plate 15, and a threaded sleeve 16. The threaded sleeve 16 is fitted onto the oil supply pipe 11, and the inner seal spanner ring 12 is fitted onto the front end of the threaded sleeve 16. The outer seal O-ring 13 is fitted onto the inner seal spanner ring 12. As shown in Figure 5, the oil supply pipe 11 has a conical horn-shaped port for clamping the inlet flange 4. The outer wall of the oil supply pipe 11 is provided with a male thread. As shown in Figure 4, the front end of the threaded sleeve 16 is openwork, and the inner wall of the threaded sleeve 16 is provided with a female thread that mates with the male thread of the oil supply pipe 11. As shown in Figure 6, the bottom end of the outer seal O-ring 13 has a round groove, the bottom of which is toothed. The inner seal spanner ring 12 is made of rubber and has a stepped end face that engages with the round groove on the bottom of the outer seal O-ring 13, allowing the outer seal O-ring 13 to be fitted onto the inner seal spanner ring 12. A flat key is provided at the rear end of the threaded sleeve 16 to securely attach the cover plate 15 and stopper disk 14, and a multi-jaw chuck mechanism 2 is attached to the outside of the stopper disk 14. The drive mechanism 3 is attached to the oil feed pipe 11, and its output shaft is provided with an output gear 35. The outer periphery of the stopper disk 14 has teeth that mesh with the output gear 35. Counterbore holes are provided in the cover plate 15, and the cover plate 15 and stopper disk 14 are fixed together with bolts. In this embodiment, three arc-shaped stopper holes are provided on the side of the stopper disk 14 to engage with the stopper locking posts 2103.

[0026] As the drive mechanism 3 rotates, it synchronously rotates the stopper disc 14 and the threaded sleeve 16. The threaded sleeve 16 moves axially along the oil pipe 11 due to the guiding action of the threads. The cover plate 15 then pushes the outer seal O-ring 13 against the inlet flange 4, forming a first-class seal. The front end of the threaded sleeve 16 is openworked. As the threaded sleeve 16 moves toward the nozzle of the oil pipe 11, the openwork portion is expanded by the conical nozzle of the oil pipe 11, pressing against the inner wall of the inner seal spanner 12. The inner seal spanner 12 expands at the conical nozzle of the oil pipe 11, pressing against the inner wall of the inlet flange 4, forming a second-class seal. At the same time, the inner seal spanner 12 pressing against the inner wall of the inlet flange 4 during operation prevents the butting device from falling off, making the operation safer and more stable.

[0027] 7 and 8, the multi-jaw chuck mechanism 2 includes a chuck 21 and a positioning disk 22. In this embodiment, the number of chucks 21 is three. The positioning disk 22 is fitted and fixed to the oil feed pipe 11 and is arranged coaxially with the stopper disk 14. The three chucks 21 are attached between the stopper disk 14 and the positioning disk 22 and are arranged circumferentially around the stopper disk 14. A plurality of slider grooves are formed in the side surface of the positioning disk 22 along the radial direction. When the stopper disk 14 rotates, the stopper locking posts 2103 slide into the arc-shaped stopper holes of the stopper disk 14, causing the slider body 2101 to slide along the slider grooves and achieving the function of clamping the inlet flange 4.

[0028] 9, the chuck 21 mainly includes a slider body 2101, a slider cover plate 2102, a stopper locking post 2103, gripping claws 2104, a spacer 2105, and a gripping claw baffle 2106. The slider body 2101 is provided in a slider groove of the positioning disk 22. The gripping claws 2104 are attached vertically to the upper end of the slider body 2101 and are used to clamp the injection port flange 4. The gripping claw baffle 2106 is attached to the end face of the gripping claws 2104 and is used to prevent the injection port flange 4 from falling off.

[0029] 10 and 11, the slider body 2101 has a hollow interior, and two spine strips 2107 are attached to both inner walls of the hollow interior by positioning pins 2108 and springs 2109. A stopper locking post 2103 is installed between the two spine strips 2107. The spring 2109 is attached to the positioning pin 2108 and presses the spine strip 2107, thereby locking the stopper locking post 2103 between the two spine strips 2107. In this embodiment, four screw holes are formed on both inner walls of the hollow interior of the slider body 2101 to fit with the positioning pins 2108, and the upper end of the slider body 2101 is a column with two screws. Conical through-holes are formed on the upper and lower ends of the spine strip 2107, respectively, to fit with the positioning pins 2108. The front end of the positioning pin 2108 is conical and the rear end is threaded, which connects and secures it within the slider body 2101. A spring 2109 is attached to the positioning pin and presses the spine strips 2107, locking the stopper locking post 2103 exactly between the two spine strips 2107. The upper end of the stopper locking post 2103 is a cylinder that engages with the arc-shaped stopper hole in the stopper disk 14, and the lower end has two strip-shaped locking pieces that engage with the spine strips 2107. The spine strips 2107 are one-way spine strips, and the stopper locking post 2103 moves the spine strip 2107 in one direction using the two strip-shaped locking pieces, allowing for adaptive clamping of inlet flanges 4 with different diameters. The self-locking function of the stopper locking post 2103 and the spine strips allows adaptive clamping of inlet flanges with different diameters, expanding the clamping range. The slider cover plate 2102 is provided with counterbore holes, and the slider cover plate 2102 is connected together with the slider body 2101 by bolts.

[0030] 12, the upper surface of the gripping claw 2104 is arc-shaped, with a groove formed thereon, the bottom surface of the groove having a toothed structure, and two waist-shaped through-holes formed in the groove for attaching a positioning spacer 2110 and a fixing nut 2111. The bottom surface of the positioning spacer 2110 has a toothed shape that meshes with the toothed structure on the bottom surface of the groove of the gripping claw 2104. The slider body 2101, gripping claw 2104, and positioning spacer 2110 are connected together by a screw on the slider body 2101 and a fixing nut 2111.

[0031] By adjusting the position of the positioning spacer 2110 in the groove of the gripping claw 2104, the relative position between the slider body 2101 and the gripping claw 2104 can be changed, allowing for clamping of inlet flanges 4 of different thicknesses and improving applicability. The lower surface of the gripping claw baffle 2106 is arc-shaped, and a countersunk hole is provided on the front end surface, and the gripping claw baffle 2106 and the gripping claw 2104 are connected and fixed by a baffle positioning bolt 2112. The lower surface of the spacer 2105 is provided with a countersunk hole, and the spacer 2105 is connected and fixed to the gripping claw 2104 by a spacer positioning bolt 2113.

[0032] The underside of the gripping claw baffle 2106 is arc-shaped and is used to match the outer contour of the inlet flange 4, and a countersunk hole is provided on the front end surface, and the gripping claw baffle 2106 and the gripping claw 2104 are connected and fixed by a baffle positioning bolt 2112. A spacer 2105 is installed on the end of the bottom surface of the gripping claw 2104 closest to the gripping claw baffle 2106, and two countersunk holes are opened in the spacer 2105, and the spacer 2105 is connected and fixed to the gripping claw 2104 by a spacer positioning bolt 2113.

[0033] As shown in FIG. 13 , the drive mechanism 3 includes a lower pipe clamp 31, an upper pipe clamp 32, a motor bracket 33, a drive motor 34, and an output gear 35. The lower pipe clamp 31 and the upper pipe clamp 32 are wrapped around the oil supply pipe 11, and the motor bracket 33 is fixedly attached to the upper pipe clamp 32. In this embodiment, the lower pipe clamp 31, the upper pipe clamp 32, and the motor bracket 33 are connected to the oil supply pipe 11 with screws. The drive motor 34 is attached to the upper end of the motor bracket 33. In this embodiment, the upper end of the motor bracket 33 is provided with a threaded hole and a positioning hole that engages with the drive motor 34, and the drive motor 34 and the motor bracket 33 are connected with screws. The output gear 35 and the shaft on the output shaft of the drive motor 34 are connected and fixed with a key. The meshing of the output gear 35 and the teeth of the stopper disk 14 allows the stopper disk 14 and the threaded sleeve 16 to rotate in tandem, achieving rapid clamping while also achieving a second-class seal between the inner seal span ring 12 and the inner wall of the injection port, improving work efficiency.

[0034] As shown in Figure 14, when the output gear 35 is in the position shown, the stopper locking column 2103 slides to the outermost part of the arc-shaped stopper hole, and the multi-jaw chuck mechanism 2 is in an open state, at which time the butting device can butt against the injection port flange 4.

[0035] As shown in Figure 15, when the output gear 35 is in the illustrated position, the stopper locking post 2103 slides to the innermost position of the arc-shaped stopper hole, and the multi-jaw chuck mechanism 2 is in a contracted state. At this time, the multi-jaw chuck mechanism 2 clamps the inlet flange 4, and the cover plate 15 presses the outer seal O-ring 13 against the inlet flange 4 to form a first-class seal, and the inner seal span ring 12 expands in the conical horn-shaped mouth of the oil transfer pipe 11 to expand the inner wall of the inlet flange 4, forming a second-class seal, and the butt joint is completed.
