Technical Field

[0001] The present invention relates to the technical field of sunken ship salvage, and particularly to an arc beam structure of a non-contact integral salvage device. Background Art

[0002] Currently, in sunken ship salvage projects, the sealing box method is used. Compared with the traditional pontoon method, it can preserve the sunken ship and the precious cultural relics on the sunken ship more completely. The method of the sealing box method is to first cover the sunken ship with a large iron box. After clearing the soil around the box body, it is sealed at the bottom of the iron box through a steel beam, and the sunken ship and the soil around the sunken ship are lifted as a whole; the pipe joints used for sealing the bottom are square straight steel beams, and difficulties such as guiding difficulties and jacking difficulties are encountered during the actual jacking of the bottom sealing steel beam. Summary of the Invention

[0003] In view of the deficiencies existing in the above-mentioned prior art, the present invention provides an arc beam structure of a non-contact integral salvage device, which can be guided in cooperation with a launching rack, and the pipe jacking machine head and the propulsion device cooperate for propulsion, and can solve problems such as guiding difficulties and jacking difficulties.

[0004] The technical solution adopted by the present invention is as follows:

[0005] An arc beam structure of a non-contact integral salvage device, which includes an arc-shaped arc beam body. The front end of the arc beam body is provided with a machine head connection end detachably connected to a pipe jacking machine head, and the tail end of the arc beam body is provided with a propulsion device connection end detachably connected to a propulsion device; locking buckles are arranged on both sides of the arc beam body along the axial direction, and are guided in cooperation with the launching racks on both sides through the locking buckles.

[0006] Optionally, the arc beam body includes an arc-shaped outer circular plate and an inner circular plate, and two parallel side plates are connected to both sides of the outer circular plate and the inner circular plate.

[0007] Optionally, the locking buckles are arranged in an arc shape throughout the side plates and have the same curvature as the arc beam body.

[0008] Optionally, end plates connected to the outer circular plate, the inner circular plate and the side plates are provided at both ends of the arc beam body.

[0009] Optionally, an installation groove for placing the pipe jacking machine head is provided on the end plate at the front end of the arc beam body, and fixing pin holes are provided at positions of the outer circular plate and the inner circular plate corresponding to the installation groove.

[0010] Optionally, a positioning groove for positioning the propulsion device is provided on the end plate at the tail end of the arc beam body, and fixing pin holes are provided at positions of the outer circular plate and the inner circular plate corresponding to the positioning groove.

[0014] Optionally, a maintenance window is opened on the outer circular plate.

[0015] Due to the adoption of the above technical solutions, the present invention has the following beneficial effects:

[0016] 1. When using a straight steel beam pipe section with the sealing box method, it is necessary to first clear the soil around the sealing box to provide construction space for the pipe jacking, resulting in a long construction period, high cost and low efficiency; the arc-shaped beam structure of the present invention only needs to use a launching rack for guiding above, without clearing the surrounding soil, which can greatly shorten the construction period;

[0017] 2. A space for installing the pipe jacking machine head is left at the front end of the arc-shaped beam structure, and fixed pin holes are designed at both ends of the arc-shaped beam structure. After the arc-shaped beam structure is advanced, the arc-shaped beam structure can be fixed on the main salvage frame of the salvage device through a pin shaft, and the fixed pin hole at the head of the arc-shaped beam structure can also be used for fixing the pipe jacking machine head. The pipe jacking machine head can be quickly disassembled and assembled at the front end. After one section of the arc-shaped beam structure is advanced, only the fixing pin shaft needs to be removed to quickly disassemble the machine head and install it on the next section of the pipe section, improving the construction speed;

[0018] 3. During traditional pipe jacking construction, the propulsion device is generally fixed on the ground and the pipe section is propelled through a jacking block.

Detailed implementation manners

[0026] The following further describes the detailed implementation manners of the present invention with reference to the drawings. It should be noted here that the description of these implementation manners is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various implementation manners of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Refer to Figures 1 to 3 As shown, the embodiment of the present invention provides an arc beam structure of a non-contact integral salvage device, which is used in cooperation with the salvage device to implement the underwater curve pipe curtain salvage method for salvaging a sunken ship. The salvage device provides a main salvage frame, which specifically includes a rectangular ring beam, and the arc beam structure of the present invention is used to surround the sunken ship and its surrounding soil together with the ring beam after jacking into the underwater soil body for salvage.

[0028] Specifically, the arc beam structure of this embodiment includes an arc-shaped arc beam body. The front end of the arc beam body is set as a nose connection end detachably connected to the pipe jacking nose, and the tail end of the arc beam body is set as a propulsion device connection end detachably connected to the propulsion device; locking buckles are provided on both axial sides of the arc beam body, and are guided in cooperation with the launch frames on both sides through the locking buckles.

[0029] Furthermore, the arc beam body includes a circular arc-shaped outer circular plate 1 and an inner circular plate 2. Two parallel side plates 3 are connected to both sides of the outer circular plate 1 and the inner circular plate 2. The inside of the arc beam body is hollow, and a mud pipeline 6 can be arranged. Grouting holes 61 communicating with the mud pipeline 6 are provided on the side plates 3 and the outer circular plate 1, which are used for lubrication when the arc beam body is jacked and reducing the pressure when lifting.

[0030] Both ends of the arc-shaped beam body are respectively provided with a front end plate 4 and a tail end plate 5 connected to the outer circular plate, the inner circular plate and the side plates. As Figure 1 shown, an oval placement groove 41 for placing the pipe jacking machine head is opened at the central position of the front end plate 4. Two fixing pin holes 7 are respectively opened at the positions of the outer circular plate 1 and the inner circular plate 2 corresponding to the placement groove 41. When the arc-shaped beam body is being advanced, the pipe jacking machine head is pre-loaded into the placement groove 41, with the cutter head exposed outside. Through holes are opened at the positions of the pipe jacking machine head corresponding to the fixing pin holes 7. By passing a pin shaft through the fixing pin holes 7 on the outer circular plate 1 and the inner circular plate 2 and the through holes on the pipe jacking machine head, the arc-shaped beam body and the pipe jacking machine head can be quickly fixed. After the arc-shaped beam body is advanced in place, by releasing the cooperation between the pin shaft and the fixing pin hole 7, the pipe jacking machine head can also be quickly disassembled from the arc-shaped beam body. Then, the front end of the arc-shaped beam body can be fixed to the ring beam of the salvage device through the cooperation between the pin shaft and the fixing pin hole. Pin shaft holes are opened at the positions of the ring beam corresponding to the fixing pin holes. Preferably, fixing holes 42 for the machine head are also provided around the front end plate 4 for further fixing the pipe jacking machine head with bolts to enhance the stability of the pipe jacking machine head during the jacking process.

[0031] As Figure 2 shown, a positioning groove 51 for positioning the propulsion device is provided on the tail end plate 5 of the arc-shaped beam body. Both ends of the positioning groove 51 extend to the two side plates 3 on both sides. Fixing pin holes 7 are also opened at the positions of the outer circular plate 1 and the inner circular plate 2 corresponding to the positioning groove 51. When the arc-shaped beam body is being advanced, the propulsion device is pre-positioned in the positioning groove 51. The propulsion device moves along the launch rack to provide the power for advancing the arc-shaped beam body. Through holes are opened at the positions of the propulsion device corresponding to the fixing pin holes 7. By passing a pin shaft through the fixing pin holes 7 on the outer circular plate 1 and the inner circular plate 2 and the through holes on the propulsion device, the arc-shaped beam body and the propulsion device can be quickly fixed. After the arc-shaped beam body is advanced in place, by releasing the cooperation between the pin shaft and the fixing pin hole 7, the propulsion device can also be quickly disassembled from the arc-shaped beam body. Then, the tail end of the arc-shaped beam body can be fixed to the ring beam of the salvage device through the cooperation between the pin shaft and the fixing pin hole. Pin shaft holes are opened at the positions of the ring beam corresponding to the fixing pin holes. Preferably, fixing holes 52 for the propulsion device are also provided around the tail end plate 5 for further fixing the propulsion device with bolts to enhance the stability of the propulsion device during the propulsion process. Among them, the propulsion device can adopt a motor or a hydraulic mechanism.

[0032] The latches on the arc-shaped beam structure in this embodiment are divided into a male latch 31 and a female latch 32, which are respectively arranged in an arc shape along the side plate 3 and are consistent with the radian of the arc-shaped beam body. Preferably, the two male latches 31 are arranged in an arc shape along the two side edges of one of the side plates 3, and the radian is consistent with the radian of the side plate. As Figure 1 and Figure 2As shown, the two male locking buckles 31 adopt U-shaped steel channels with the opening directions facing the outer circular plate 1. The two female locking buckles 32 are also arranged in an arc along the two side edges of the other side plate 3, and the arc is the same as that of the side plate. The two female locking buckles 32 adopt U-shaped steel channels with the opening directions facing outwards and are bent inside the side wall box on the same side, as Figure 1 and Figure 2 shown. Above the ring beam of the salvage device, arc-shaped launchers are respectively fixed at the positions corresponding to the two side plates of the arc beam structure, and the arc is the same as that of the arc beam structure. The male locking buckles 31 and the female locking buckles 32 on the two side plates 3 are slidably matched with the two side launchers. The launchers are provided with guiding chutes, and during the advancement of the arc beam structure, guiding is carried out through the launchers.

[0033] Furthermore, the two end ports of the mud water pipeline in the arc beam structure are respectively arranged on the front end plate 4 and the tail end plate 5. A maintenance window 11 is opened on the outer circular plate 1, which allows people to enter for maintenance.

[0034] The structural principle of the arc beam structure of the present invention is as follows: Since the underwater curve pipe curtain salvage method is adopted in construction, the arc beam structure is made of customized arc pipe sections with a cross-sectional area of 1m×2m. The two sides of the arc beam structure can be connected with locking buckles by bolts. Except for one section with double male locking buckles, all the other arc beam structures are male and female locking buckles. Windows are opened on the outer circle of the arc beam, which allows people to enter for maintenance. An oval placement groove 41 is opened at the connection end of the machine head of the arc beam structure, into which the pipe jacking machine head can be placed and fixed through the machine head fixing pin holes 7 and pins, realizing the quick disassembly and assembly of the pipe jacking machine head. A propulsion device positioning groove 51 is designed at the propulsion connection end for the positioning of the propulsion device, and propulsion device fixing holes 52 are opened, which can realize the quick disassembly and assembly of the propulsion device. Fixing pin holes 7 for fixing with the ring beam are opened at both ends of the arc beam structure. After the advancement of one section of the arc beam structure is completed, the arc beam structure is fixed to the ring beam through the fixing pin holes 7. A number of mud water pipelines are installed in the whole arc beam structure, and grouting holes are opened on both sides and the outer arc of the arc beam structure for lubrication during propulsion and reducing pressure during lifting. After the advancement of all the arc beam structures is completed, all the arc beam structures and the ring beam will surround the sunken ship and the soil around it and salvage them together.

[0035] The advantages of adopting the arc beam structure of the non-contact integral salvage device of the present invention are as follows:

[0036] 1. When using straight steel beam pipe sections in the box sealing method, it is necessary to first clear the soil around the box to provide construction space for the pipe jacking. The construction period is long, the cost is high, and the efficiency is low; the arc beam structure of the present invention only needs to use the launchers for guiding above, without clearing the surrounding soil, and can greatly shorten the construction period;

[0037] 2. A space for installing the pipe jacking machine head is left at the front end of the arc-shaped beam structure, and fixed pin holes are designed at both ends of the arc-shaped beam structure. After the arc-shaped beam structure is pushed forward, the arc-shaped beam structure can be fixed to the main salvage frame of the salvage device through a pin shaft. Moreover, the fixed pin hole at the head of the arc-shaped beam structure can also be used for fixing the pipe jacking machine head, enabling the rapid disassembly and assembly of the pipe jacking machine head at the front end. After one section of the arc-shaped beam structure is pushed forward, only by removing the fixed pin shaft can the machine head be quickly disassembled and installed on the next pipe section, improving the construction speed.

[0038] 3. During traditional pipe jacking construction, the propulsion device is generally fixed on the ground and the pipe section is pushed through a jacking block. In the present invention, a propulsion device positioning groove and a fixed pin hole are provided at the end of the arc-shaped beam structure. During propulsion, it moves forward together with the arc-shaped beam structure, and like the pipe jacking machine head, the rapid disassembly and assembly of the propulsion device can be carried out.

[0039] 4. A mud pipeline is installed inside the arc-shaped beam structure, and grouting holes are opened on both sides and the outer arc of the arc-shaped beam structure. Cooperating with the mud pipeline, it has a lubricating function during propulsion and can synchronously grout during hoisting, facilitating the overall hoisting.

[0040] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
