Description

Technical Field

[0001] The invention relates to the technical field of underwater jacking, in particular to a continuous propulsion device using an arc-beam curved pipe curtain method. Background Art

[0002] In traditional underwater salvage projects, the buoy method is usually adopted, that is, a number of buoys are directly tied to the objects to be salvaged, and the objects are directly lifted to the surface with the help of the buoyancy generated by the buoys. However, this salvage method often causes irreparable damage to relatively fragile objects. In the Nanhai No. 1 shipwreck salvage project in Guangzhou, the sealing box method was used. A large iron box was first used to cover the shipwreck, and then the bottom of the iron box was sealed with steel beams. The shipwreck and the soil around the shipwreck were lifted as a whole. Compared with the traditional salvage method, this method can more completely protect the shipwreck and salvage it from the water. However, the on-site operation is difficult, the construction risk is high, and the construction process will consume more time and manpower.

[0003] To this end, the applicant proposed a construction scheme for arc-shaped beam jacking, which allows the arc-shaped beam to jack along an arc-shaped path to complete the bottom sealing of the salvaged object. Compared with the box sealing method, it can reduce the construction difficulty and construction risk. Regarding the arc-shaped beam jacking scheme, the applicant's prior patent (application number 201510507860.9, invention name: Curved pipe segment clamping and propulsion device) discloses a curved pipe segment clamping and propulsion device, which is provided with multiple clamping assemblies on the clamping bracket, which are used to clamp the curved pipe segment, and a propulsion assembly is provided at the rear to propel the curved pipe segment. The clamping assembly and the propulsion assembly are used in combination, so that the pipe segment is pushed forward or retracted while being clamped. Although this technical solution can achieve curved jacking of curved pipe segments, it is not suitable for underwater operations. The jacking scheme has multiple clamping assemblies and many parts, which makes it difficult to repair when a fault occurs underwater. In addition, the propulsion assembly at the rear needs to have sufficient thrust to achieve curved jacking, which results in high construction costs. Summary of the Invention

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] See Figure 1 The present invention provides a continuous propulsion device for a curved beam using a curved pipe curtain method, which is used to solve the problem that the existing curved pipe segment clamping propulsion device has too many parts and components and is not suitable for underwater operations, and the rear propulsion assembly needs to increase sufficient thrust, which makes the construction cost high. The propulsion device of the present invention uses the meshing of gears and racks to provide propulsion force, which can save costs and reduce the parts of the propulsion device. It is suitable for underwater construction operations, and the meshing of gears and racks can play a guiding role in the advancement of the curved beam, ensuring the accuracy of the advancement of the curved beam. Furthermore, the propulsion device of the present invention is also used to solve the problem that the existing curved pipe segment clamping propulsion device cannot accurately predict whether the curved beam is advanced into place, which easily generates the risk of the curved beam falling off. The propulsion device of the present invention is provided with a limit block, which can accurately know whether the curved beam is advanced into place, reducing construction risks and ensuring construction safety. The continuous propulsion device for a curved beam using a curved pipe curtain method of the present invention is described below with reference to the accompanying drawings.

[0034] See Figure 1 , showing a cross-sectional view of the curved beam propelled by the continuous propulsion device of the curved beam curve tube curtain method of the present invention. Figure 3 , shows the structural diagram of the continuous propulsion device of the curved beam curved pipe curtain method of the present invention except the driving rack. Figure 1 and Figure 3 , the continuous propulsion device of the curved beam curved pipe curtain method of the present invention is described.

[0035] like Figure 1 and Figure 3As shown, the continuous propulsion device of the curved beam curved pipe curtain method of the present invention includes a driving rack 21, an installation shell 22, a driving head 23 and a driving gear 24, wherein the driving rack 21 is installed in an arc-shaped launching frame 11, and a launching space 111 is formed inside the launching frame 11, and the launching space 111 is also arc-shaped. The launching space 111 is used to accommodate the propulsion device and the curved beam 12, and the driving rack 21 is also arc-shaped; an installation space 221 is formed inside the installation shell 22, and the end 22a of the installation shell 22 is formed with a connecting end 222 for connecting to the curved beam 12; the driving mechanism 23 is arranged on the installation shell 22 and is located in the installation space 221; the driving gear 24 is connected to the driving mechanism 23, and the driving gear 24 is arranged on both sides of the installation shell 21, that is, the driving gear 24 is provided at the side 22b of the installation shell 21, and the driving gear 24 is meshed and connected with the driving rack 21.

[0036] Specifically, when the curved beam 12 is pushed forward, the curved beam 12 is first placed in the launching space 111 inside the launching frame 11, and then Figure 6 and Figure 7 As shown, the propulsion device is then connected to the end of the arc beam 12, the driving gear 24 on the propulsion device engages with the driving rack 21 in the launcher 11, and then the driving mechanism 23 drives the corresponding driving gear 24 to rotate, and then the driving gear 24 moves along the driving rack 21, combined with Figure 1 and Figure 2 As shown, the driving gear 24 enters the launching frame 11 and pushes the arc beam 12 to the outside of the launching frame 11, thereby advancing the arc beam 12.

[0037] The propulsion device of the present invention is mounted at the tail end of the curved beam and propels the curved beam through the meshing of a gear and rack. This coordination guides the propulsion of the curved beam, ensuring precise propulsion and adapting to harsh underwater environments. The propulsion device also has fewer components, reducing underwater malfunctions and, consequently, the workload of divers. The number of drive mechanisms and drive gears can be selected based on actual needs, enabling the propulsion of the curved beam without the need for expensive, large-scale power equipment, effectively reducing construction costs.

[0038] In a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, there are multiple mounting housings 22, each of which is provided with a driving mechanism 23 and a driving gear 24. Two adjacent mounting housings 22 are connected via a connecting end 222. In this way, the number of power sources, i.e., the number of mounting housings, driving mechanisms, and driving gears, can be selected according to the actual thrust required by the curved beam 12. Figure 3In the illustrated embodiment, two power sources are shown, and the corresponding connection ends 222 of the two mounting housings 22 are butt-connected.

[0039] The connecting end 222 at one end 22a of the installation shell 22 is connected to the curved beam 12, and the connecting end 222 at the other end 22a is used to connect to another installation shell 22. In this way, when the pushing force is insufficient, a new power source can be added conveniently and timely, that is, the installation shell, the driving mechanism and the driving gear. When the arc beam 12 encounters difficulties in pushing forward, the power for the pushing construction of the arc beam can be increased to complete the pushing construction of the arc beam.

[0040] In a specific embodiment of the present invention, Figure 3 and Figure 5 As shown, a mounting opening 223 is provided on the side portion 22 b of the mounting housing 21 , and the driving gear 24 extends from the corresponding mounting opening 223 to the outside of the mounting housing 21 .

[0041] In a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, the driving mechanism 23 includes a driving motor 231 and a reducer 232 connected to the driving motor 231 . The driving motor 231 and the reducer 232 are arranged corresponding to the driving gear 24 , and the reducer 232 is connected to the mounting housing 22 .

[0042] Drive gears 24 are provided on both sides of the mounting shell 22. Each drive gear 24 is connected to a drive motor 231 and a reducer 232. The drive motor 231 is installed on the mounting shell 22 through the reducer 232. The corresponding drive gear 24 is driven to rotate by the drive motor 231 and the reducer 232.

[0043] In a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, the mounting housing 22 includes a left housing 224 and a right housing 225 that are connected to each other. At least one driving mechanism 23 and a driving gear 24 are provided on the left housing 224 and the right housing 225.

[0044] The left shell 224 and the right shell 225 are symmetrical structures. The structures of the left shell and the right shell are described below using the left shell 224 as an example. Figure 5As shown, the left housing 224 includes two end plates 2243, side plates 2242, and a docking plate 2244. The two end plates 2243 are arranged opposite each other, and the side plates 2242 and docking plate 2244 are arranged opposite each other and connected on both sides of the two end plates 2243, thereby forming a square structure with a hollow interior. The docking plate 2244 is provided with bolt holes and is connected to the docking plate on the right housing 225 via bolts. The side plates 2242 are provided with mounting holes 223, which are used to pass the drive gear. The space formed inside the left housing 224 is used to accommodate the drive mechanism 23.

[0045] Preferably, two mounting ports are provided on the side plate 2242 of the left housing 224, so that the left housing 224 can be connected to two driving gears 24 and two driving mechanisms 23. Figure 1 and Figure 9 As shown, the driving rack 21 arranged in the launch frame 11 is provided with engaging teeth on the mating surface corresponding to the driving gear 24. The two driving gears 24 are clamped on the upper and lower sides of the driving rack 21 and respectively engage with the corresponding engaging teeth. This improves the stability of the driving gear 24 moving along the driving rack 21, thereby improving the stability of the arc beam propulsion.

[0046] In a preferred embodiment, if Figure 5 As shown, there are two side panels 2242, which are arranged opposite to each other. Each side panel 2242 has an installation opening, and each side panel 2242 has a reinforcement ring 2245 at the installation opening. The reinforcement ring 2245 is arranged along the edge of the installation opening, and a plurality of stiffening plates 2246 are connected between the reinforcement ring 2245 and the side panel 2242. The reinforcement ring 2245 and the stiffening plates 2246 on the inner side panel 2242 are attached to the outer side panel 2242. A plurality of bolt holes are provided on the side panel 2242, and the bolt holes are located between two adjacent stiffening plates 2246. Figure 4 As shown, the reducer 232 is connected to the reducer 232 through the bolt hole. The end of the reducer 232 is provided with a flange plate, which is also provided with bolt holes. Bolts are inserted into the aligned bolt holes to connect the reducer 232 to the two side plates 2242. The provision of the two side plates plays a role in strengthening the structural strength of the driving gear 24.

[0047] Furthermore, if Figure 3 and Figure 4 As shown, positioning grooves 2241 and 2251 are provided at the ends of the left shell 224 and the right shell 225. Figure 5 As shown, the positioning groove 2241 is provided on the end plate 2243 of the left shell 224. Through the setting of the positioning groove, the left shell and the right shell that are docked are positioned, and the left shell and the right shell can be quickly aligned, thereby connecting the docking plates of the left shell and the right shell.

[0048] Preferably, a positioning groove is provided on the side portion 22 b of the mounting shell 22 , and another mounting shell 22 can be quickly positioned and aligned through the positioning groove, thereby achieving rapid positioning and connection of the two mounting shells 22 .

[0049] In a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, the end 22a of the mounting housing 22 is provided with a connecting plate 226, and a side of the connecting plate 226 close to the inner wall of the launcher 11 is provided with an escape opening 2261. The escape opening 2261 is provided in the middle of the connecting plate 226. The provision of the escape opening 2261 facilitates the laying of pipelines within the launcher 11 and ensures smooth movement of the propulsion device within the launcher 11.

[0050] Combine Figure 1 As shown, the interior of the launcher 11 is hollow, formed with an upper arcuate wall, a lower arcuate wall, a left arcuate wall, and a right arcuate wall. The connecting plate 226 is provided with escape openings 2261 on the sides corresponding to the upper and lower arcuate walls. Drive racks 21 are provided on the left and right arcuate walls, and the drive gears 24 on the sides of the propulsion device mesh with the corresponding drive racks 24.

[0051] In a specific embodiment of the present invention, Figure 3 and Figure 11 As shown, a limit block 227 is provided at the connection end 222 of the mounting shell 22 connected to the arc-shaped beam 12, and a portion of the limit block 227 protrudes from the edge of the mounting shell 22. And a portion of the limit block 227 also protrudes from the edge of the arc-shaped beam 12. When the arc-shaped beam 12 is pushed into place, the limit block 227 can be stuck on the top beam 131 connected to the launcher 11, so that the limit block 227 limits the movement of the drive gear 24, and prevents the drive gear 24 from detaching from the launcher 11. And the setting of the limit block 227 can also prompt the completion of the pushing construction through the stopping effect of the limit block 227. Preferably, a pressure sensor can be provided on the side of the limit block 227 facing the top beam 131. When the limit block 227 contacts the top beam 131, the pressure sensor detects the pressure, and then forms a pressure signal to be sent to the control end, so that the control end can promptly know that the arc-shaped beam has been pushed into place. Preferably, as Figure 2 As shown, a top beam 131 is provided at the construction position of the curved beam 12, and an end plate 132 is connected between the top beams 131 on both sides, so that the top beam 131 and the end plate 132 are connected to form a platform, and the launching frame 11 is installed on the top beams 131 on both sides, and the curved beam 12 placed in the launching frame 11 can be pushed into the soil between the top beams 131 on both sides.

[0052] In a specific embodiment of the present invention, Figure 8 and Figure 10As shown, a rotatable guide wheel 25 is provided on the side of the mounting shell 22 inside the launcher 11 , and there are multiple guide wheels 25 that are arranged at intervals.

[0053] The guide wheel 25 can contact the side of the mounting shell 22. When the mounting shell 22 moves in the launcher 11, the corresponding guide wheel 25 can roll on the side of the mounting shell 22. The setting of the guide wheel 25 can clamp and position the mounting shell 22, preventing the mounting shell 22 from moving left and right, ensuring the stability of the position of the mounting shell 22, and ensuring that the drive gear 24 is meshed with the drive rack 21. The free rotation of the guide wheel 25 also reduces the friction resistance between it and the mounting shell 22.

[0054] Preferably, freely rotatable guide wheels 25 are installed on the surface of the drive rack 21 opposite to the side portion 22b of the mounting housing 22, and the guide wheels 25 are arranged at intervals along the drive rack 21. A sealing plate 26 is provided on the side portion 22b of the mounting housing 22 corresponding to the guide wheel 25, and the sealing plate 26 can contact the corresponding guide wheel 25.

[0055] When two driving gears 24 are provided on one side of the mounting housing 21 , the sealing plate 26 is provided between the two driving gears 24 .

[0056] In a specific embodiment of the present invention, Figure 4 As shown, the upper and lower edges of the side of the mounting shell 22 are arc-shaped edges 228 , and the curvature of the arc-shaped edges 228 matches the curvature of the launcher 11 .

[0057] The launching frame 11 is arc-shaped, the arc-shaped beam 12 is also arc-shaped, and the launching space 111 formed in the launching frame 11 is also arc-shaped. The launching space 111 is used to accommodate the arc-shaped beam 12. The upper and lower edges of the mounting shell 22 are also designed to be arc-shaped, which can ensure that the mounting shell 22 moves smoothly in the launching space 111 to prevent collision.

[0058] The beneficial effects of the arc-beam curved pipe curtain method continuous propulsion device of the present invention are:

[0059] The propulsion device of the present invention has a high degree of automation, can adapt to various harsh environments, can reduce the workload of divers, and has a short construction period.

[0060] The propulsion device of the present invention can achieve continuous propulsion and high-precision propulsion throughout the entire process. The gear and rack are engaged, and the thrust is stable along the tangential direction of the arc, and can propel along the arc by itself.

[0061] In the process of advancing the curved beam, the driving mechanism can also drive the corresponding driving gear to rotate in the opposite direction to realize the retraction function of the curved beam. When encountering special working conditions, the curved beam can be retracted.

[0062] When the propulsion force is insufficient, the power source can be conveniently added to ensure the smooth completion of the propulsion construction of the curved beam.

[0063] A limit block is provided on the mounting shell to prevent the push-out stroke and to promptly know whether the curved beam is pushed into place.

[0064] The edge of the mounting shell is curved to facilitate smooth advancement and prevent collisions. A clearance opening is provided on the mounting shell to accommodate pipelines.

[0065] The present invention has been described in detail above with reference to the embodiments of the accompanying drawings.
