Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine operation technology, and in particular to a loading arm for a scoop-type loading module of a pipe laying device for a marine operation platform. Background Technology
[0002] Currently, the pipe laying device on marine operation platforms uses a sack-type loading module to unbundle, straighten, and spread out bundled pipes, and then transport the sorted pipes one by one to the next work station. The sack-type loading module is usually equipped with a loading arm, which is used to feed pipes from the external pipe laying frame into the sack-type loading module, or to remove sorted pipes from inside the sack-type loading module, thus realizing the transfer of pipes between the pipe laying frame and the sack-type loading module.
[0003] However, existing feeding arms typically use a single hook structure, which uses a hook to pick up the tubing from one place and move it to another. When outputting the tubing, it is spread out and aligned before being extruded from the outlet. However, because the tubing is prone to crossing during the alignment process, multiple tubing often get stuck at the outlet and cannot be extruded smoothly. In this case, the machine needs to be stopped and manual intervention is required to clear the stuck tubing before the operation can continue, which affects the efficiency of the operation. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a loading arm for a scoop-type loading module of a pipe laying device for marine operation platforms, so that the loading arm can actively remove individual pipes when outputting pipes, avoiding machine stoppage caused by pipe cross-blocking.
[0005] To achieve the above objectives, this utility model provides a loading arm for a hopper-type loading module of a pipe-laying device for a marine operation platform, comprising:
[0006] The boom is rotatably mounted on the support frame of the scoop-type feeding module;
[0007] The loading hook is rotatably mounted on one end of the arm body and is used to hook the external pipe column. The loading hook can be rotated in one direction relative to the arm body.
[0008] An elastic reset component is connected between the feeding hook and the arm body, and is used to reset the feeding hook after it flips over;
[0009] The loading arm also includes:
[0010] A hook is provided at the other end of the arm body, and the hook forms a holding space for accommodating a single pipe column, for hooking and tilting the single pipe column when the arm body rotates.
[0011] The hook is an L-shaped hook, and the bending angle of the L-shaped hook is less than 90 degrees.
[0012] The arm body is rotatably mounted on the support frame via a rotating shaft, which is a long shaft and is an integral part of the arm body.
[0013] The feeding arm also includes a limiting block, which is fixedly mounted on the arm body and located above the tail of the feeding hook, to restrict the tip of the feeding hook from turning upwards only.
[0014] The elastic reset component is a tension spring, with one end connected to the feeding hook and the other end connected to the arm.
[0015] The upper surface of the arm is equipped with a shock-absorbing plate for reducing vibration and noise of the rolling column.
[0016] The feeding hook is equipped with a shock-absorbing plate in the area where it contacts the tubular column.
[0017] The feeding hook is hinged to the arm body via a feeding hook connecting pin.
[0018] The feeding hook has an interception position that is held in the hooking position under the action of a tension spring, and an avoidance position that flips upward to avoid obstacles by overcoming the elastic force of the tension spring under the action of external force.
[0019] The arm is driven by a hydraulic cylinder to rotate around a pivot.
[0020] The beneficial effects of this utility model are as follows: By setting L-shaped hooks and unidirectional flip-up loading hooks at both ends of the same arm, the same loading arm can not only achieve the hanging and tilting output of a single pipe column through the acute angle bending structure of the L-shaped hook, but also achieve the avoidance and protection of the pipe rack through the unidirectional flip-up of the loading hook. Combined with the buffering and noise reduction effect of the shock-absorbing plate, it solves the problems of easy blockage at the output and easy collision at the input of the pipe column in the pocket-type loading module.

[0029] Currently, the pipe-laying device on marine operation platforms uses a sack-type loading module to achieve the unbundling, spreading, and orderly transport of pipe strings. (Refer to...) Figure 1 The hopper-type feeding module includes a first skid, two U-shaped frames 8, multiple belt drums 9, a discharge valve 10, and a wire rope belt 11. The two U-shaped frames 8 are fixedly installed at both ends of the first skid, forming an enclosed structure that provides circumferential constraint on the unbundled tubing. Multiple belt drums 9 are respectively positioned at the upper ends of the first skid and the U-shaped frames 8. One end of the wire rope belt 11 is hinged to the U-shaped frame 8, and the other end passes through the belt drum 9 and connects to the drive mechanism. The drive mechanism extends and retracts the wire rope belt 11, causing the tubing inside the U-shaped frame 8 to continuously rise and fall, thereby achieving the smoothing and spreading of the tubing. A discharge valve 10 is provided at the outlet of the U-shaped frame 8, through which the tubing is discharged one by one after spreading and smoothing. A detachable mounting bracket is provided on the crossbeam of the U-shaped frame 8 for mounting the feeding arm.
[0030] Reference Figure 1 and Figure 2 This utility model provides a feeding arm for the aforementioned hopper-type feeding module. The overall structure of the feeding arm includes an arm body 2, an L-shaped hook 14, a feeding hook 1, and a tension spring 5.
[0031] Reference Figure 2 and Figure 4 In this embodiment, the arm 2 is a long strip structure, rotatably mounted on a detachable support on the crossbeam of the U-shaped frame 8 via a pivot 3. The pivot 3 is a long shaft that passes through one end of the arm 2 and is an integral part of the arm 2. Both ends of the pivot 3 are rotatably mounted on detachable supports on the crossbeams on both sides of the U-shaped frame 8, allowing the arm 2 to swing around the pivot 3 in a vertical plane. The arm 2 is driven by a hydraulic cylinder to rotate around the pivot 3. The cylinder body of the hydraulic cylinder is hinged to the base of the scoop-type feeding module, and the piston rod of the hydraulic cylinder is hinged to the arm 2. The extension and retraction of the hydraulic cylinder drives the arm 2 to swing back and forth around the pivot 3.
[0032] Reference Figure 4 In this embodiment, a shock-absorbing plate 4 is provided on the upper surface of the arm body 2. The shock-absorbing plate 4 is made of polyurethane or rubber and is laid on the upper surface of the arm body 2. It is used to reduce vibration and noise of the pipe column when the pipe column rolls along the upper surface of the arm body 2, and reduce rigid collisions between the pipe column and the arm body 2.
[0033] The loading arm has two functional ends: one end is the output end, which is equipped with an L-shaped hook 14 for removing the pipe columns in the U-shaped frame 8 one by one and dumping them to the outside; the other end is the input end, which is equipped with a loading hook 1 for hooking the pipe columns from the external pipe rack 13 and sending them into the U-shaped frame 8.
[0034] Reference Figure 2 and Figure 4 One end of the boom 2 (i.e., the output end) is equipped with an L-shaped hook 14. The L-shaped hook 14 is fixedly installed at the tail end of the boom 2, with a bending angle of less than 90 degrees, and is L-shaped in general. The L-shaped hook 14 forms a holding space for accommodating a single pipe column. When the pipe column in the U-shaped frame 8 rises under the drive of the wire rope belt 11, the uppermost pipe column enters the holding space and is held by the L-shaped hook 14, realizing the hanging and retrieval of a single pipe column.
[0035] Reference Figure 4 In this embodiment, the bending angle of the L-shaped hook 14 is less than 90 degrees (i.e., the opening angle of the L-shaped hook 14 is an acute angle), so that once the tube enters the holding space, it is stably held and will not accidentally come out due to vibration or tilting. At the same time, the bent part of the L-shaped hook 14 blocks other tubes behind it, ensuring that only one tube can be hung at a time, thereby achieving single-tube orderly output.
[0036] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the other end (i.e., the input end) of the arm body 2 is provided with a loading hook 1. The loading hook 1 is hinged to the arm body 2 via a loading hook connecting pin 7, so that the loading hook 1 can rotate relative to the arm body 2 around the loading hook connecting pin 7. The tip of the loading hook 1 extends outward for hooking the pipe column on the pipe rack 13.
[0037] Reference Figure 4 In this embodiment, a limiting block 6 is fixedly installed on the arm body 2, and the limiting block 6 is located above the tail of the feeding hook 1. When the feeding hook 1 flips downward around the feeding hook connecting pin 7, the limiting block 6 abuts against the tail of the feeding hook 1, preventing the feeding hook 1 from continuing to flip downward, thereby restricting the tip of the feeding hook 1 to only flip upward. When the feeding hook 1 flips upward, the limiting block 6 does not interfere.
[0038] Reference Figure 4 In this embodiment, a tension spring 5 connects the feeding hook 1 and the arm body 2. One end of the tension spring 5 hooks into the ear plate hole at the tail of the feeding hook 1, and the other end hooks into the cylinder inside the arm body 2. The tension spring 5 is always in a taut state, applying a downward pulling force to the feeding hook 1, so that the tip of the feeding hook 1 remains in the hooking position (i.e., the interception position) when no external force is applied. When the tip of the feeding hook 1 flips upward under the action of an external force, the tension spring 5 is further stretched; after the external force disappears, the elastic restoring force of the tension spring 5 pulls the feeding hook 1 back to the hooking position.
[0039] Reference Figure 4 In this embodiment, a damping plate 4 is provided in the area where the feeding hook 1 contacts the tube column. Specifically, the damping plate 4 is disposed on the inner side of the tip of the feeding hook 1 and the hooking surface, and is used to buffer the tube column at the moment the feeding hook 1 contacts the tube column, reduce the damage to the tube column surface caused by rigid contact, and reduce contact noise. The damping plate 4 is made of polyurethane or rubber.
[0040] Based on the above structure, the feeding hook 1 has two working states: one is the interception position (i.e., the hooking position), where the feeding hook 1 is held in a horizontal or slightly downward hooking posture under the tension of the tension spring 5, with its tip facing the pipe rack 13, ready to hook the pipe column; the other is the avoidance position, where when the tip of the feeding hook 1 encounters an obstacle (such as other pipe columns or supports on the pipe rack 13) during its descent, the obstacle pushes the tip of the feeding hook 1 to overcome the elastic force of the tension spring 5 and flip upward, allowing the feeding hook 1 to avoid the obstacle and prevent damage from a rigid collision with the obstacle. After the obstacle passes, the elastic restoring force of the tension spring 5 pulls the feeding hook 1 back to the interception position.
[0041] Working principle: The loading arm of the scoop-type loading module for the pipe laying device of this utility model for marine operation platform has two working principles: pipe output and pipe input.
[0042] When the tubing is output, refer to Figure 2 The wire rope belt 11 extends and retracts, driving the pipe columns within the U-shaped frame 8 to rise and fall, smoothing and spreading them out. During the rising process, the uppermost pipe column enters the holding space of the L-shaped hook 14 and is held by it. Subsequently, the hydraulic cylinder drives the arm 2 to rotate around the pivot 3, lifting the tail end of the arm 2 upwards, flipping the pipe column on the L-shaped hook 14 out of the arm 2. The pipe column rolls out of the U-shaped frame 8 along the guide ramp 12 and falls into the subsequent work position. After the pipe column is detached, the hydraulic cylinder drives the arm 2 to reset, ready for the next hooking and retrieval. During this process, because the bending angle of the L-shaped hook 14 is less than 90 degrees, only one pipe column can be held at a time, thus achieving single-column orderly output and effectively avoiding mutual collisions and blockages caused by multiple pipe columns rushing out simultaneously.
[0043] When inputting the tubing, refer to Figure 4 The boom 2 rotates around the pivot 3, lowering the tip of the loading hook 1 to the height of the pipe rack 13. The tip of the loading hook 1 hooks a single pipe column on the pipe rack 13. Then, the hydraulic cylinder drives the boom 2 to rotate in the opposite direction, and the loading hook 1 lifts the pipe column. The pipe column rolls along the shock-absorbing plate 4 on the upper plane of the boom 2 and enters the U-shaped frame 8 through the discharge gate 10. After entering the U-shaped frame 8, the pipe column is lifted and lowered smoothly by the wire rope belt 11. During the descent of the boom 2, if the tip of the loading hook 1 encounters other pipe columns or supports on the pipe rack 13, the tip will be pushed by the obstacle and overcome the elastic force of the tension spring 5 to flip upward, thus avoiding a rigid collision with the obstacle. After the boom 2 returns to its position, the elastic restoring force of the tension spring 5 pulls the loading hook 1 back to the intercept position, ready for the next hooking. The damping plate 4 acts as a buffer and noise reduction when the tube column rolls along the upper plane of the arm body 2 and when the feeding hook 1 contacts the tube column, reducing scratches and impact noise on the tube column surface.
