[0025] The technical solutions of the present application will be further described below in conjunction with the embodiments and the drawings.

[0026] As shown in Figure 1 , 2 , a marine hook box steel pipe limiting device of an embodiment of the present application comprises:

[0027] The main body 1 comprises a limiting sleeve 101 and a mounting seat 102, the mounting seat 102 is mounted on the fixed structure 3, the limiting sleeve 101 is arranged on the mounting seat 102, the limiting sleeve 101 is provided with a pipe passing hole 1011 along its radial direction, and the pipe passing hole 1011 is used for the steel pipe to pass through;

[0028] The limiting assembly 2 comprises a limiting part 201 and a locking piece 202. The limiting part 201 is rotationally arranged on the limiting sleeve 101. One end of the limiting part 201 is used for abutting against the steel pipe passing through the pipe hole 1011. The locking piece 202 is connected with the other end of the limiting part 201. The locking piece 202 is movably arranged on the mounting seat 102. The locking piece 202 has a locking position and an unlocking position in the movable range. When the locking piece 202 is located at the locking position, the one end of the limiting part 201 can abut against the steel pipe passing through the pipe hole 1011. When the locking piece 202 is located at the unlocking position, the one end of the limiting part 201 does not abut against the steel pipe passing through the pipe hole 1011.

[0029] According to the above technical scheme, when the locking piece 202 is located at the unlocking position, the locking piece 202 can pass through the pipe hole 1011 of the limiting sleeve 101. After passing through, the locking piece 202 is switched to the locking position. The limiting part 201 abuts against the steel pipe and applies a certain pressure to the steel pipe, thereby preventing the steel pipe from sliding in the pipe hole 1011 and achieving locking and limiting of the steel pipe. A plurality of offshore hook box steel pipe limiting devices are arranged on the same straight line. The extending directions of the pipe holes 1011 of the offshore hook box steel pipe limiting devices are consistent. The steel pipes passing through the offshore hook box steel pipe limiting devices are radially limited. Each limiting part 201 can apply segmented force to the steel pipe to abut against the steel pipe, thereby axially limiting the sliding of the steel pipe and achieving omnidirectional locking and limiting. The steel pipe can be effectively prevented from deviating or rotating, thereby ensuring the stability of transportation.

[0030] Preferably, the limiting sleeve 101 extends in the up-down direction. One end of the limiting sleeve 101 is connected with the mounting seat 102. The limiting sleeve 101 is provided with a clearance hole 1012 in the radial direction. The limiting sleeve 101 is provided with a hinged part 103 on the outer wall. The hinged part 103 is located below the clearance hole 1012. The limiting part 201 comprises a first swing arm 2011 and a second swing arm 2012. The middle part of the first swing arm 2011 is hinged in the clearance hole 1012. The middle part of the second swing arm 2012 is hinged on the hinged part 103. The upper end of the second swing arm 2012 abuts against the lower end of the first swing arm 2011. The locking piece 202 comprises a locking bolt 2021. The locking bolt 2021 sequentially passes through the lower end of the second swing arm 2012, the limiting sleeve 101 and is screwed with the mounting seat 102 in the radial direction of the limiting sleeve 101.

[0031] Based on the above technical scheme, when the locking member 202 is switched from the unlocking position to the locking position, the locking bolt 2021 gradually rotates into the mounting seat 102, the second swing arm 2012 rotates around the hinge part 103, the lower end of the second swing arm 2012 is close to the limiting sleeve 101, the upper end of the second swing arm 2012 is away from the limiting sleeve 101, the upper end of the second swing arm 2012 pushes the first swing arm 2011 to rotate, the lower end of the first swing arm 2011 is pushed away from the limiting sleeve 101 by the upper end of the second swing arm 2012, and the upper end of the first swing arm 2011 can abut against the steel pipe passing through the pipe hole 1011. At this time, the locking bolt 2021 continues to rotate into the mounting seat 102, and the upper end of the first swing arm 2011 can exert pressure on the steel pipe passing through the pipe hole 1011 to lock the steel pipe; when the locking member 202 is switched from the locking position to the unlocking position, the locking bolt 2021 gradually rotates out of the mounting seat 102, but the bolt does not come out of the mounting seat 102, the second swing arm 2012 rotates around the hinge part 103, the lower end of the second swing arm 2012 is away from the limiting sleeve 101, the upper end of the second swing arm 2012 is close to the limiting sleeve 101, the pushing force of the upper end of the second swing arm 2012 on the first swing arm 2011 gradually decreases, until the upper end of the second swing arm 2012 is no longer in abutment with the lower end of the first swing arm 2011, and the upper end of the first swing arm 2011 releases the force exerted on the steel pipe. At this time, the locking is invalid, and the steel pipe can slide along the pipe hole 1011.

[0032] More preferably, the first swing arm 2011 comprises an abutment arm body 20111 and a counterweight arm body 20112, one end of the abutment arm body 20111 is connected to one end of the counterweight arm body 20112, and the abutment arm body 20111 and the counterweight arm body 20112 are arranged at an angle, and the angle between the abutment arm body 20111 and the counterweight arm body 20112 is 110°-130°. The provision of the counterweight arm body 20112 can ensure that the lower end of the first swing arm 2011 is always in contact with the upper end of the second swing arm 2012 when the pipe hole 1011 is not inserted into the steel pipe, thereby avoiding the abutment arm body 20111 rotating to the pipe hole 1011 when the steel bar passes through the pipe hole 1011, and the need for workers to adjust the steel pipe passing through the pipe hole 1011 by pushing; the angle between the abutment arm body 20111 and the counterweight arm body 20112 is preferably 120°. If the angle is less than 110°, the rotation path of the first swing arm 2011 is too short, resulting in a short switching path between the locking position and the unlocking position of the locking member 202, which may, in the event of an emergency, cause the locking member 202 to be easily switched from the locking position to the unlocking position, resulting in invalid locking and positioning of the steel bar and causing a safety problem. If the angle is greater than 130°, the rotation path of the second swing arm 2012 is too long, which is not conducive to the compact design of the structure of the offshore hook box steel pipe limiting device.

[0033] In a specific embodiment, the lower end of the second swing arm 2012 has an extension section 20121, the extension direction of the extension section 20121 is consistent with the extension direction of the second swing arm 2012, the locking bolt 2021 passes through the extension section 20121 and the limiting sleeve 101 in sequence and is screwed with the mounting seat 102, in the first swing arm 2011, the length of the counterweight arm body 20112 is greater than that of the abutting arm body 20111, through the principle of lever, the long displacement of the screwing of the locking bolt 2021 is converted into the pressure of the abutting arm body 20111 on the steel pipe, even if the locking bolt 2021 has a small range of position floating, the pressure on the steel pipe can still be maintained, and since the locking bolt 2021 is screwed with the mounting seat 102, the locking member 202 is difficult to switch from the locking position to the unlocking position without human intervention, even if a sudden situation occurs, the locking bolt 2021 will not be rotated out with a large stroke at once, and the locking and limiting of the steel pipe are maintained.

[0034] More preferably, the hinge between the first swing arm 2011 and the let-in hole 1012 is located on the abutting arm body 20111, and the hinge between the first swing arm 2011 and the let-in hole 1012 is located close to the connection between the abutting arm body 20111 and the counterweight arm body 20112. The connection between the abutting arm body 20111 and the counterweight arm body 20112 is arranged in a staggered manner with the hinge between the first arm body and the let-in hole 1012, and on the rotation path of the first swing arm 2011, the connection between the abutting arm body 20111 and the counterweight arm body 20112 can abut against the let-in hole 1012, limiting the rotation range of the first swing arm 2011, reducing unnecessary rotation positions of the first swing arm 2011, so as to reduce the additional operation of the construction personnel on the equipment adjustment.

[0035] More preferably, the offshore hook box steel pipe limiting device comprises at least two limiting assemblies 2, the limiting sleeve 101 is centrally and symmetrically provided with at least two let-in holes 1012, and the let-in holes 1012 are hingedly connected with the first swing arms 2011 one by one. By arranging at least two limiting assemblies 2, the single-point abutment on the steel pipe is changed to multi-point abutment, the force applied to the steel pipe is more uniform, and when the locking member 202 of one limiting assembly 2 fails to lock, the locking members 202 of the remaining limiting assemblies 2 can still maintain the locking function, ensuring the safety of the structure.

[0036] More preferably, the mounting base 102 comprises a pre-embedded part 1021, a base body 1022 and mounting bolts 1023, one end of the limiting sleeve 101 is arranged on the base body 1022, the pre-embedded part 1021 is pre-embedded on the fixed structure 3, the pre-embedded part 1021 is provided with mounting holes 10211, the mounting holes 10211 are internally threaded, and the mounting bolts 1023 pass through the base body 1022 and are engaged with the mounting holes 10211 to mount the base body 1022 on the pre-embedded part 1021. The pre-embedded part 1021 is arranged on the fixed structure 3, and the base body 1022 is detachably mounted on the pre-embedded part 1021 through the mounting bolts 1023. If the base body 1022 and the structure arranged on the base body 1022 are damaged, they can be replaced in time, which is convenient and fast.

[0037] More preferably, the mounting base 102 further comprises mounting blocks 1024, the base body 1022 is provided with mounting grooves 10221, part of the mounting blocks 1024 is fitted and embedded into the mounting grooves 10221, and the remaining part protrudes from the mounting grooves 10221. A plurality of adjusting holes 10241 are arranged on the outer circumferential wall of the mounting blocks 1024 protruding from the mounting grooves 10221, the adjusting holes 10241 correspond one-to-one to the limiting assemblies 2, the adjusting holes 10241 are internally threaded, the locking bolts 2021 are engaged with the adjusting holes 10241, and the mounting bolts 1023 extend in the up-down direction and pass through the mounting blocks 1024, the base body 1022 and the mounting holes 10211 in sequence and are engaged with the mounting holes 10211.
