Description

Technical Field

[0001] The present invention relates to the technology of oil loading and unloading, and specifically to an adjustable and rapid butting device for an oil replenishment crane pipe.

Background Art

[0002] When refueling an oil tanker, when the oil replenishment crane pipe approaches the inlet, the conventional oil replenishment crane pipe needs to manually align the crane pipe joint and the inlet. After the alignment is completed, the crane pipe joint needs to be further manually operated and clamped with the inlet flange. Since many processes are completed manually, there are problems such as high labor intensity, poor safety, and low efficiency. At the same time, due to the lack of specifications and standards regarding the production design of the inlets of oil tankers, currently, there is no unified regulation on the dimensions of oil tankers and inlet flanges. There are significant differences in the diameter and thickness dimensions of the inlet flanges of different oil tankers, and the conventional crane pipe joints cannot be properly aligned with some inlets, resulting in ineffective sealing between the crane pipe joint and the inlet.

[0003] Also, currently, many butting methods all adopt a single rubber sealing method. Such a sealing method has problems of insufficient sealing due to the aging deterioration and deformation of the rubber during long-term use, and ultimately there is a problem of oil and gas leakage, which poses certain safety problems.

[0004] Therefore, the invention of an adjustable automatic butting device is very necessary.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The object of the present invention is to provide an adjustable and rapid butting device for an oil replenishment crane pipe that can solve the problem of insufficient sealing when the conventional crane pipe joint and the oil tanker are butted to replenish oil.

Means for Solving the Problem

[0006] The adjustable quick butt-joint device for an oil replenishment crane pipe of the present invention includes a sealing mechanism, a multi-jaw chuck mechanism, and a driving mechanism. The sealing mechanism includes an oil delivery pipe, a screw sleeve fitted to the oil delivery pipe, an inner sealing schrumpf ring fitted to the front end of the screw sleeve, and an outer sealing O-ring fitted to the inner sealing schrumpf ring. Here, the pipe orifice of the oil delivery pipe is provided as a conical trumpet orifice and is used for clamping the injection port flange. At the rear end of the screw sleeve, a flat key for fixedly attaching a cover plate and a stopper disk is provided. An outer side of the stopper disk is attached with a multi-jaw chuck mechanism. The driving mechanism is attached to the oil delivery pipe, and an output gear is provided on its output shaft. Teeth meshing with the output gear are provided on the outer periphery of the stopper disk. A male screw is provided on the outer wall of the oil delivery pipe, and a female screw meshing with the male screw of the oil delivery pipe is provided on the inner wall of the screw sleeve. When the driving mechanism rotates, the stopper disk and the screw sleeve are synchronously rotated, and the stopper disk rotates to expand and contract the gripping claws of the multi-jaw chuck mechanism, realizing the grasping and unloading of the injection port flange. The screw sleeve moves along the axial direction of the oil delivery pipe by the guiding action of the screw. Further, the cover plate presses the outer sealing O-ring to press the injection port flange to form a primary seal. The front end portion of the screw sleeve is engraved with a watermark and is used for pressing the inner wall of the inner sealing schrumpf ring to expand the inner sealing schrumpf ring at the conical trumpet orifice of the oil delivery pipe, thereby pressing the inner wall of the injection port flange to form a secondary seal.

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

[0008] Furthermore, each chuck includes a slider body installed in the slider groove of the positioning disk, a gripping claw vertically attached to the upper end of the slider body for clamping the injection port flange, and a gripping claw baffle attached to the end face of the gripping claw for preventing the injection port flange from falling off. The plurality of chucks can engage with each other to realize the grasping and unloading of the injection port flange.

[0009] Furthermore, the interior of the slider body has a hollow structure. On both inner side walls of the hollow structure, two spine strips are attached by positioning pins and springs. Between the two spine strips, a stopper locking post is installed. The spring is attached to the positioning pin and presses the spine strip, so that the stopper locking post is locked between the two spine strips, 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 two strip-shaped locking pieces that engage with the spine strip are provided at the lower end. The spine strip is a one-way spine strip. The stopper locking post is used to move the spine strip in one direction by the two strip-shaped locking pieces to adaptively clamp injection port flanges with different diameters, expanding the clamping range.

[0011] Furthermore, the stopper locking post slides in the arc-shaped stopper hole of the stopper disk. When the stopper locking post slides to the outermost side of the arc-shaped stopper hole, the multi-jaw chuck mechanism is in an open state. When the stopper locking post slides to the innermost side of the arc-shaped stopper hole, the multi-jaw chuck mechanism is in a contracted state.

[0012] Furthermore, the upper surface of the gripping claw is arc-shaped, on which a concave groove is formed. The bottom surface of the concave groove has a tooth-shaped structure. Two waist-shaped through holes for attaching a positioning spacer and a fixing nut separately are formed in the concave groove. The bottom surface of the positioning spacer is tooth-shaped and meshes with the tooth-shaped structure of the bottom surface of the concave groove of the gripping claw. The slider body, the gripping claw, and the positioning spacer are integrally connected by a screw and a fixing nut in the slider body, realizing the assembly of the main structure of the chuck.

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

[0014] Furthermore, the lower surface of the gripping claw baffle is provided as arc-shaped and is used to match the outer contour of the injection port flange. A counterbore is provided on its front end face. The gripping claw baffle and the gripping claw are connected and fixed by a baffle positioning bolt. A spacer is installed at the end of the bottom surface of the gripping claw close to the gripping claw baffle. A counterbore for connecting and fixing to the gripping claw by a spacer positioning bolt is formed in the spacer. By installing the gripping claw baffle, it can be prevented that the injection port flange is pressed and drops off during clamping, and wear of the spacer against the injection port flange during clamping can be prevented.

[0015] Furthermore, the drive mechanism includes a lower pipe clamp and an upper pipe clamp wrapped by an 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. The output gear and the shaft body on the output shaft of the drive motor are connected and fixed by a key. The output gear is driven by the drive motor to rotate the entire stopper disk and the screw sleeve.

Advantages 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 secondary seal structure with relatively good sealing effect. At the same time, the inner seal spring ring presses the inner wall of the injection port flange, resulting in better sealing performance. Also, during oil supply, due to the pressing action between the inner seal spring ring and the inner wall of the injection port, the butting device is less likely to fall off and is safer and more stable.

[0018] The present invention can adaptively clamp injection port flanges with different diameters and expand the clamping range through the self-locking function of the stopper locking column and the spline strip engaging within the slider.

[0019] The present invention can adapt to injection port flanges with different wall thicknesses and improve its applicability by adjusting the relative positions of the positioning spacer and the gripping claws in the groove.

[0020] The present invention drives the gear by a driving motor to integrally rotate the stopper disk and the screw sleeve, realizing fast clamping and at the same time realizing sealing, and improving the working efficiency.

[0024] As shown in Fig. 1, the adjustable quick alignment device for an 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 Figs. 2 and 3, the sealing mechanism 1 consists of an oil delivery pipe 11, an inner seal spring ring 12, an outer seal O-ring 13, a stopper disk 14, a cover plate 15, a screw sleeve 16, etc. The screw sleeve 16 is fitted onto the oil delivery pipe 11, and the inner seal spring ring 12 is fitted onto the front end of the screw sleeve 16. The outer seal O-ring 13 is fitted onto the inner seal spring ring 12. As shown in Fig. 5, the pipe orifice of the oil delivery pipe 11 is provided as a conical trumpet orifice and is used to clamp the injection port flange 4, and male threads are provided on the outer wall of the oil delivery pipe 11. As shown in Fig. 4, the front end portion of the screw sleeve 16 is engraved with a watermark, and female threads meshing with the male threads of the oil delivery pipe 11 are provided on the inner wall of the screw sleeve 16. As shown in Fig. 6, a round groove is opened at the bottom end of the outer seal O-ring 13, and the groove bottom is tooth-shaped. The inner seal spring ring 12 is made of a rubber material, and a step is provided on the end face. The step can engage with the bottom round groove of the outer seal O-ring 13 to fit the outer seal O-ring 13 onto the inner seal spring ring 12. A flat key for fixing and attaching the cover plate 15 and the stopper disk 14 is provided at the rear end of the screw sleeve 16, and the multi-jaw chuck mechanism 2 is attached to the outside of the stopper disk 14. The driving mechanism 3 is attached to the oil delivery pipe 11, and an output gear 35 is provided on its output shaft.

In this embodiment, three arc-shaped stopper holes for engaging with the stopper locking posts 2103 are opened on the side surface of the stopper disk 14.

[0026] When the drive mechanism 3 rotates, the stopper disk 14 and the screw sleeve 16 are synchronously rotated. The screw sleeve 16 moves along the axial direction of the oil supply pipe 11 under the guiding action of the screw. Further, the cover plate 15 presses the outer seal O-ring 13 Note Inlet flange 4 For to form a primary seal. The front end portion of the screw sleeve 16 is embossed. In the process of the screw sleeve 16 moving towards the nozzle of the oil supply pipe 11, the embossed portion is expanded by the conical trumpet mouth of the oil supply pipe 11, thereby pressing the inner wall of the inner seal spring ring 12 and expanding the inner seal spring ring 12 at the conical trumpet mouth of the oil supply pipe 11, so as to press the inner wall of the injection port flange 4 and form a secondary seal. At the same time, during operation, due to the pressing action of the inner seal spring ring 12 on the inner wall of the injection port flange 4, the butting device is not easily detached, and is safer and more stable.

[0027] As shown in FIGS. 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 set to three. The positioning disk 22 is fitted and fixed to the oil supply pipe 11 and is provided coaxially with the stopper disk 14. The three chucks 21 are attached between the stopper disk 14 and the positioning disk 22 and are installed circumferentially around the stopper disk 14. A plurality of slider grooves are opened along the radial direction on the side surface of the positioning disk 22. When the stopper disk 14 rotates, the slider body 2101 is slid along the slider groove by sliding the stopper locking post 2103 into the arc-shaped stopper hole of the stopper disk 14, so as to realize the function of clamping the injection port flange 4.

Due to the self-locking function of the stopper locking post 2103 and the spine strip, injection port flanges with different diameters can be adaptively clamped, and the clamping range can be expanded. The slider cover plate 2102 is provided with a countersunk hole, and the slider cover plate 2102 is integrally connected by bolts and the slider body 2101.
