Description

Technical Field

[0001] The invention relates to the technical field of marine engineering, and in particular to an underwater sandbag placing tool and a use method thereof. Background Art

[0002] The connection between the offshore floating structure and the submarine pipeline needs to be connected through expansion bends or risers and other connecting pipelines to transport oil or natural gas and subsequent hydrogen. It is particularly important to protect and backfill the connecting pipelines and submarine pipelines.

[0003] When performing submarine pipeline maintenance and repair operations, handling submarine pipeline crossings, or installing underwater structures such as submarine manifolds and expansion bends, it is often necessary to provide sandbag support or backfill protection, or to bury the pipeline using methods such as sand and stone throwing or covering with cement blocks. However, this requires precise positioning and underwater operation by divers or underwater robots, resulting in low construction safety and efficiency.

[0004] For the problem of accurate underwater backfilling, the existing solutions at home and abroad are: (1) Use positioning and conduit for backfilling. First, use the positioning equipment to move the end of the conduit to the position where backfilling is required, and put the prepared sandbags from the upper end of the conduit. The sandbags fall to the seabed along the direction of the conduit due to gravity. The above operations are repeated to achieve accurate backfilling of small areas. This method requires a conduit and a lot of manpower, and the efficiency is very low. (2) The crane directly lifts the sandbags and lowers them. Divers command the lowering position of the sandbags underwater and then unhook them. The construction resource requirements are large. The underwater operations of divers are affected by the sea conditions and other environmental factors, and the efficiency is very low.

[0005] Therefore, the traditional underwater backfilling scheme has a large amount of manual labor, low construction efficiency and safety hazards. Summary of the invention

[0006] The purpose of the present invention is to provide an underwater sandbag placing tool and a method for using the same, so as to alleviate the technical problems existing in the prior art of traditional underwater backfilling schemes, such as large manual labor, low construction efficiency and potential safety hazards.

[0007] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0008] In a first aspect, the underwater sandbag placing tool provided by the present invention comprises: a hanging beam body, a clamping member, a pushing connecting rod and a transmission assembly;

[0009] The clamp members are arranged in plurality at intervals along the length direction of the suspension beam body;

[0010] The clamp member comprises a fixed part and a rotating part, wherein the fixed part is fixed on the suspension beam body, and the rotating part is rotatably connected to the fixed part;

[0011] The pushing connecting rod is connected to the plurality of rotating parts;

[0012] The transmission assembly is rotatably connected to the end of the suspension beam body, and the transmission assembly is connected to the end of the push link. The transmission assembly is configured to be rotatable relative to the suspension beam body so that the transmission assembly drives the push link to move, and controls the rotation of the plurality of rotating parts relative to the fixed part so that the clamp member is opened or closed.

[0013] Furthermore, the fixing portion has a rotation hole, and the rotating portion is rotatably connected to the fixing portion through the rotation hole.

[0014] Furthermore, the fixing portion has an arc hole, and the rotating portion has a sliding pin, and the sliding pin extends into the arc hole so that the rotating portion slides along the arc path formed by the arc hole.

[0015] Furthermore, the fixed part has a fixed hook, and the rotating part has a rotating hook. When the fixed hook and the rotating hook are closed to each other, the sandbag can be lifted.

[0016] Furthermore, limiting blocks are provided on both sides of the rotating hook in the thickness direction, and the two limiting blocks and the end of the rotating hook form a clamping groove, and the fixed hook can extend into the clamping groove and abut against the rotating hook.

[0017] Further, the transmission assembly includes a rotating connection member and a pushing connection member;

[0018] One end of the rotating connection piece is rotatably connected to the end of the suspension beam body, the other end of the rotating connection piece is connected to the pushing connection piece, and one end of the pushing connection piece away from the rotating connection piece is connected to the pushing connecting rod;

[0019] The rotating connection piece is configured to be pushed by a hydraulic driving member so that the rotating connection piece rotates relative to the suspension beam body, and the pushing connection piece pushes the pushing link to move.

[0020] Further, the rotating connecting member is configured to be L-shaped, the lateral end of the L-shaped rotating connecting member is rotatably connected to the suspension beam body, and the vertical end of the L-shaped rotating connecting member is used to be connected to the hydraulic drive component;

[0021] The connection between the horizontal side and the vertical side of the L-shaped rotating connecting member is connected to the pushing connecting member.

[0022] Furthermore, the underwater sandbag placing tool also includes a bracket;

[0023] The bracket supports the two suspension beam bodies.

[0024] In a second aspect, the method for using the underwater sandbag placing tool provided by the present invention comprises the following steps:

[0025] Before lowering sandbags for backfilling, install the beacon on the bracket to locate the precise backfilling position. The beacon installation position is determined according to the construction requirements. After all preparations are completed, lift the main body of the beam with a crane, control the clamp component to open through the hydraulic drive component, connect the prepared sandbags, and finally control the hydraulic power station to close the beam clamp.

[0026] Furthermore, the method further comprises the following steps:

[0027] When using a crane to control the main body of the crane beam to lower sandbags for backfilling, it is necessary to use two front and rear traction ropes to adjust the underwater posture and direction of the crane beam. With the assistance of moving ships and beacons, the sandbags connected to the clamp components are accurately placed on the required seabed position, and the hydraulic drive components are controlled to open, and the sandbags are accurately backfilled.

[0028] Based on the above technical solutions, the technical effects that can be achieved by the present invention are:

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0042] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the underwater sandbag placing tool provided in this embodiment includes: a suspension beam body 100, a clamp member 200, a push connecting rod 300 and a transmission assembly 400; a plurality of clamp members 200 are evenly spaced along the length direction of the suspension beam body 100, and the clamp members 200 are located at the bottom of the suspension beam body 100; the clamp member 200 includes a fixed portion 210 and a rotating portion 220, the fixed portion 210 is fixed on the suspension beam body 100, and the rotating portion 220 is rotatably connected to the fixed portion 210, so that the rotating portion 220 can rotate around the fixed portion 210, that is, the rotation of the rotating portion 220 enables the clamp member 200 to have an open state and a closed state, when the clamp member 200 is in the closed state, the rotating portion 220 rotates to a position where the end portion abuts against the end portion of the fixed portion 210, so that the sandbag can be clamped and fixed.

[0043] The pushing link 300 is located below the suspension beam body 100, and the pushing link 300 is connected to a plurality of rotating parts 220; the transmission assembly 400 is rotatably connected to the end of the suspension beam body 100, and the transmission assembly 400 is connected to the end of the pushing link 300. The transmission assembly 400 is configured to be rotatable relative to the suspension beam body 100, so that the transmission assembly 400 drives the pushing link 300 to move, and the pushing link 300 drives the plurality of rotating parts 220 to rotate relative to the fixed part 210. The opening or closing of the clamp member 200 can be controlled by moving the pushing link 300.

[0044] The underwater sandbag placing tool further comprises a bracket 500 , which supports two suspension beam bodies 100 , and a suspension ring is arranged on the bracket 500 for connecting with a crane.

[0045] The underwater sandbag placing tool provided in this embodiment is achieved by installing multiple clamp components 200 on the suspension beam main body 100, the fixed part 210 in the clamp component 200 is fixed on the suspension beam main body 100, and a transmission component 400 is installed at the end of the suspension beam main body 100, the transmission component 400 rotates relative to the suspension beam main body 100 to drive the push link 300 to move, and since the push link 300 is connected together with the multiple rotating parts 220, the multiple rotating parts 220 rotate together relative to the fixed parts 210 connected to them, so that the multiple clamp components 200 can be driven to open or close at the same time by controlling the transmission component 400, which effectively improves construction efficiency, ensures personnel safety, and alleviates the technical problems of traditional underwater backfilling schemes in the prior art, such as large amount of manual labor, low construction efficiency, and potential safety hazards.

[0046] like Figure 3 On the basis of the above embodiments, further, the fixing part 210 in the underwater sandbag placing tool provided in this embodiment has a rotating hole 211, and the rotating part 220 is rotatably connected to the fixing part 210 through the rotating hole 211.

[0047] Specifically, a rotating hole 211 is provided on the fixing portion 210 , a connecting through hole is provided on the rotating portion 220 at a position corresponding to the rotating hole 211 , and the rotating shaft passes through the rotating hole 211 and the connecting through hole, so that the rotating portion 220 rotates around the position of the rotating hole 211 .

[0048] Furthermore, the fixing portion 210 has an arc hole 212 , and the rotating portion 220 has a sliding pin 221 . The sliding pin 221 extends into the arc hole 212 , so that the rotating portion 220 slides along the arc path formed by the arc hole 212 .

[0049] Specifically, in order to enable the rotating part 220 to slide along the arc path, an arc hole 212 is opened on the fixed part 210, and a sliding pin 221 is passed through the rotating part 220. The sliding pin 221 extends into the arc hole 212, so that the sliding pin 221 can slide in the arc hole 212, so that the rotating part 220 rotates relative to the fixed part 210.

[0050] Furthermore, the fixed portion 210 has a fixed hook 213, and the rotating portion 220 has a rotating hook 222. When the fixed hook 213 and the rotating hook 222 are closed to each other, the sandbag can be lifted.

[0051] Specifically, a fixed hook 213 and a rotating hook 222 are respectively provided at the end of the fixed portion 210 and the end of the rotating portion 220. The fixed hook 213 and the rotating hook 222 are arranged opposite to each other. When the clamp member 200 is in a closed state, the fixed hook 213 and the rotating hook 222 are relatively abutted.

[0052] When the hanging beam main body 100 is actually used, it is easy for the clamp component 200 to fail to clamp the sandbags. There are two reasons for this. First, there are many mechanical parts connected inside the hanging beam. There are gaps between the parts and between the pins. When the gaps accumulate, the whole is not tight enough. Second, there are many sandbags per ton bag, weighing more than 1 ton. As long as there is a little gap in the clamp component 200, the ton bag will slip out.

[0053] In response to the above problems, Figure 4 As shown, it is finally determined to increase the length and strengthen one side of the clamp member 200, increase the length and strengthen the theoretical size, and leave no gap when the clamp member 200 is in the closed state. Specifically, limit blocks 223 are provided on both sides of the rotating hook 222 along the thickness direction, and the two limit blocks 223 and the end of the rotating hook 222 form a clamping groove, and the fixed hook 213 can extend into the clamping groove and abut against the rotating hook 222.

[0054] Furthermore, the transmission assembly 400 includes a rotating connection member 410 and a pushing connection member 420; one end of the rotating connection member 410 is rotatably connected to the end of the suspension beam body 100, and the other end of the rotating connection member 410 is connected to the pushing connection member 420, and the end of the pushing connection member 420 away from the rotating connection member 410 is connected to the pushing link 300; the rotating connection member 410 is configured to be able to be pushed by a hydraulic drive component so that the rotating connection member 410 rotates relative to the suspension beam body 100, and the pushing connection member 420 pushes the pushing link 300 to move.

[0055] Specifically, the rotating connection member 410 is configured to be L-shaped, the lateral end of the L-shaped rotating connection member 410 is rotatably connected to the suspension beam body 100, and the vertical end of the L-shaped rotating connection member 410 is used to connect to the hydraulic drive component; the connection between the lateral side and the vertical side of the L-shaped rotating connection member 410 is connected to the pushing connection member 420.

[0056] The hydraulic driving component can be specifically configured as a hydraulic jack. The driving force generated by the hydraulic driving component acts on the rotating connecting member 410. The rotating connecting member 410 rotates relative to the suspension beam body 100, driving the pushing connecting member 420 to move, and then driving the pushing connecting rod 300 to move. The hydraulic jack is controlled by manual operation to achieve the effect of controlling the hook release of the suspension beam body 100.

[0057] like Figure 7 As shown, the method for using the underwater sandbag placing tool provided in this embodiment includes the following steps: before lowering the sandbags for backfilling, the beacon is installed on the bracket 500 to locate the precise backfilling position. The beacon installation position is determined according to the construction requirements. After all preparations are completed, the hanging beam main body 100 is lifted by a crane, and the clamp component 200 is controlled to open by the hydraulic drive component, the prepared sandbags are connected, and finally the hydraulic power station is controlled to close the hanging beam clamp.

[0058] When using a crane to control the main beam 100 to lower sandbags for backfilling, it is necessary to use two front and rear traction ropes to adjust the underwater posture direction of the beam. With the assistance of moving ships and beacons, the sandbags connected to the clamp component 200 are accurately placed at the required seabed position, and the hydraulic drive component is controlled to start, and the sandbags are accurately backfilled.

[0059] The method for using the underwater sandbag placing tool provided in this embodiment uses the underwater sandbag placing tool designed and manufactured by itself to perform precise underwater backfilling, adopts beacon positioning, traction adjustment and ship movement to achieve precise backfilling in place of sandbags, realizes batch and smooth lowering of sandbags, and achieves the effect of hydraulic control of hook release through the connection of hydraulic drive components and mechanical structures, avoids the natural backfilling method that takes a long time and has high pipeline risks, and the mechanical backfilling method that has high requirements for ships and will cause damage to pipelines, and is not affected by environmental sea conditions, ensuring the safety of personnel and equipment, and greatly improving construction efficiency and construction efficiency.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
