Description

Technical Field

[0001] The utility model relates to a detachable supporting base and belongs to the technical field of construction protection facilities. Background Art

[0002] There are usually safety guardrails on the edge of the deck of the offshore wind power hoisting platform. In addition, when adding a new expansion platform structure or an extended platform structure, guardrails are required to ensure safety.

[0003] When carrying out offshore wind power operations, for example, when installing a wind turbine tower, a pedestrian bridge needs to be built between the hoisting platform and the wind turbine foundation transition platform, or when carrying out offshore wind turbine impeller assembly operations, it is necessary to remove a certain part of the railing. Therefore, the protective railing needs to have the function of being removable and installable.

[0004] Although the existing support base (see Chinese patent announcement number CN214886048U) discloses that the telescopic rod and the sleeve rod can be retracted and unfolded through a buckle to achieve detachability, there is a gap after the buckle is inserted into the buckle of the sleeve rod, which causes water such as seawater to enter the interior of the support base and easily cause oxidation damage. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a detachable supporting base.

[0006] The utility model is realized through the following technical solutions.

[0029] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0030] like Figures 1 to 7 shown.

[0031] The present invention relates to a detachable handrail with an oblique support, comprising:

[0032] The vertical pole 1 is in an upright state during installation. The vertical pole 1 is a galvanized steel pipe. The vertical pole 1 made of the galvanized steel pipe can effectively reduce seawater corrosion. The vertical pole 1 is a plurality of vertical poles distributed at intervals. A rope ring 11 is welded and fixed on the vertical pole 1. The rope ring 11 is penetrated by a railing rope 12. The railing rope 12 is made of steel rope or the like.

[0033] The vertical poles 1 at the two end positions are equipped with detachable elastic connection joints 2, one end of the detachable elastic connection joint 2 is tied and fixedly connected to the railing rope 12 on the vertical pole 1 in the middle position, and the other end of the detachable elastic connection joint 2 is hooked and connected to the rope rings 11 on the vertical poles 1 at the two end positions.

[0034] The bottom of the vertical pole 1 is detachably fixed with a support base 3. When in use and installation, the bottom of the vertical pole 1 is detachably fixed on the deck edge 5 of the offshore wind power hoisting platform through the support base 3. In order to make the vertical pole 1 have a certain resistance strength in the sea breeze environment after installation, the vertical pole 1 needs to be strengthened. The vertical pole 1 is installed with a diagonal bracing structure 4 for diagonal bracing reinforcement.

[0035] Since the railing rope 12 passes through the rope ring 11 of the middle position upright pole 1, the detachable elastic connection joint 2 tied with the railing rope 12 itself is detachable; and the bottom of the upright pole 1 is detachably fixedly installed on the edge of the deck of the offshore wind power lifting platform through the support base 3. When the upright pole 1 needs to be disassembled, it can be detachably installed with the upright pole 1 through the detachable elastic connection joint 2 and the support base 3, which solves the problem that the connection between the steel rope and the upright pole cannot be detachably installed.

[0036] Although the prior art (see Chinese patent announcement number CN219176032U) realizes a detachable fixed connection by tying a steel wire rope to a fixed ring, the tying connection is tightened after the sea breeze blows, which causes the tying connection to be inconvenient to disassemble.

[0037] A detachable elastic connection joint 2 of the present application comprises:

[0038] A fixed joint 21 hooked and connected with the rope threading ring 11 on the vertical pole 1 at both ends; the end of the fixed joint 21 has an external thread that can be detachably fixed and screwed together with a threaded cap A22, and the threaded cap A22 has an internal thread that is screwed together with the external thread at the end of the fixed joint 21;

[0039] The threaded cap A22 is welded or integrally formed and fixed on the cylinder 23. A rectangular through hole 231 is provided in the middle of the cylinder 23 for the crowbar to be inserted into to rotate the cylinder 23 under force. A twisting cylinder 232 is installed on the cylinder 23.

[0040] The end of the cylinder 23 away from the threaded cap A22 is welded or integrally formed with a threaded cap B24, and the threaded cap B24 has an internal thread that is detachably fixed and screwed to a U-shaped ring 25, and the U-shaped ring 25 has an external thread that is detachably fixed and screwed to the internal thread of the threaded cap B24, and the U-shaped ring 25 has a U-shaped opening, and the U-shaped ring 25 at the end of the U-shaped opening is penetrated by a pin 26, and a limit pin 27 is inserted on the end of the pin 26; the railing rope 12 is penetrated and tied around the pin 26 in the U-shaped opening of the U-shaped ring 25. The U-shaped ring 25 is detachably fixed and screwed to the threaded cap B24, and the threaded cap A22 is detachably fixed and screwed to the fixed joint 21, and the detachable elastic connection joint 2 tied to the railing rope 12 itself is detachable, and the screw connection will not be tightened after the sea breeze blows, which is convenient for screwing and disassembly, solving the problem that the tied connection method is tightened after the sea breeze blows and is inconvenient to disassemble.

[0041] A detachable support base 3 of the present application includes:

[0042] The support steel pipe 31 has a hollow through hole inside, and a circular base 38 is welded and fixed to the bottom of the support steel pipe 31. When in use, the circular base 38 is welded and fixed to the edge of the deck of the offshore wind power hoisting platform;

[0043] The vertical pole 1 is inserted from the top of the support steel pipe 31. The support steel pipe 31 is provided with a through hole 32 with a connecting pin 33 passing through it. The vertical pole 1 is detachably fixedly connected to the support steel pipe 31 through the connecting pin 33; waterproof caps 34 are installed on both sides of the connecting pin 33. The waterproof caps 34 are made of elastic rubber material to block the through hole 32 to prevent water from entering, thereby solving the problem of oxidation damage caused by water entering.

[0044] The waterproof cap 34 is a cone, and when installed, the small end of the cone-shaped waterproof cap 34 faces outward and away from the vertical side of the pole 1.

[0045] The end of the connecting pin shaft 33 is provided with a tying through hole, and the tying through hole of the connecting pin shaft 33 is tied with an anti-slip rope 35 , and the anti-slip rope 35 is fixedly bonded to the outer side of the support steel pipe 31 .

[0046] The end of the connecting pin shaft 33 away from the anti-offset rope 35 can be rotatably hinged to the limiting rod 37 through the limiting shaft 36. The end of the connecting pin shaft 33 on which the anti-offset rope 35 is installed has a step larger than the through hole 32. The limiting rod 37 rotates and droops along the limiting shaft 36 to exceed the lower extension of the through hole 32, thereby realizing the limiting of the connecting pin shaft 33 by the limiting rod 37.

[0047] A convenient and detachable diagonal bracing structure 4 of the present application comprises:

[0048] The inclined support member 41 is rigid in itself, and two ends of the inclined support member 41 are correspondingly welded and fixedly connected with double-ear plates 43 through connecting plates 42, and the double-ear plates 43 are provided with hinged through holes;

[0049] The hinged through hole on the double-ear plate 43 is hinged with a single-ear plate 44 through an ear plate bolt 45, and the single-ear plate 44 is located in the middle of the double-ear plate 43 with a gap; the end of the ear plate bolt 45 is provided with an external thread and screwed with an adjusting nut 46, and the adjusting nut 46 is screwed into the ear plate bolt 45 to adjust the gap between the single-ear plate 44 and the double-ear plate 43. A corrugated column 47 capable of generating elasticity is installed between the end of the single-ear plate 44 and the connecting plate 42, and the corrugated column 47 is made of elastic rubber to generate elastic force.

[0050] When the dynamic load of the sea breeze causes the end of the inclined support member 41 with the double ear plates 43 to rotate around the single ear plate 44 with the ear plate bolts 45, it is necessary to slowly overcome the elastic damping of the corrugated column 47 to ensure that the two ends of the inclined support member 41 will not shake or rotate excessively. This solves the problem that the inclined support is installed in a hinged form at both ends, which may cause excessive shaking and disconnection at the hinges at both ends of the inclined support under the dynamic load of the sea breeze.

[0051] The single-ear plate 44 located at the bottom of the inclined support member 41 is welded and fixed with a seat plate 48 , and the single-ear plate 44 is welded and fixed to the deck edge 5 of the offshore wind power hoisting platform through the seat plate 48 .

[0052] By removing the ear plate bolts 45 and the adjusting nuts 46, the diagonal bracing structure 4 can be conveniently disassembled and assembled. The single ear plate 44 located at the top of the diagonal support member 41 is welded and fixed on the upright pole 1, so that the diagonal support member 41 is in an inclined state.

[0053] When installed on the deck edge 5 of the offshore wind power hoisting platform, the vertical pole 1 is welded and fixed on the deck edge of the offshore wind power hoisting platform through the circular base 38 of the support base 3, and the railing rope 12 passes through the rope ring 11 on the vertical pole 1 at the middle position; the fixed joint 21 of the detachable elastic connection joint 2 is hooked and connected with the rope ring 11 on the vertical pole 1 at the two end positions, and the two ends of the railing rope 12 are correspondingly tied around and fixed with the pin shaft 26 of the detachable elastic connection joint 2; the bottom of the oblique support member 41 of the oblique support structure 4 is fixed by the seat plate 48 On the deck side of the offshore wind power hoisting platform, the oblique support member 41 is tilted, and the single ear plate 44 on the top of the oblique support member 41 is fixed on the vertical pole 1; the U-shaped ring 25 and the threaded cap B24 are disassembled at the screw connection, or the threaded cap A22 and the fixed joint 21 are disassembled at the screw connection, so that the detachable elastic connection joint 2 and the railing rope 12 installed on the vertical pole 1 can be disassembled, thereby constructing an application method of the detachable elastic connection joint 2, which solves the problem that the connection between the steel rope and the vertical pole cannot be detachably installed.
