[0003] During the operation of the construction personnel, safety protection problems are particularly prominent due to the particularity of the offshore environment; the safety measures commonly used at present are limited to wearing life jackets, and there is a lack of temporary support points for hanging safety belts when ascending and descending the structure, crossing or measuring, which can easily cause operation risks; at the same time, the wind and wave on the sea are large, and the construction platform and the surface of the component are often wet and slippery, undulating or shaking, the personnel standing stability is poor, and the construction operation difficulty is obviously increased; the existing safety protection means is insufficient and cannot provide reliable temporary protection points for the construction personnel.

[0004] At present, auxiliary installation of structure fixing is usually achieved by hard connection methods such as bolts and steel bars, but this method not only has complex construction and poor flexibility, but also cannot be quickly disassembled and reused after completion, which is not conducive to the temporary positioning and the movement and arrangement of the construction measurement points; especially when multiple point measurement and dynamic positioning are involved, the existing method cannot efficiently respond to the construction needs.

[0053] As one of the optional implementation modes:

[0054] Regarding the connection structure of the above power supply rod 1 and the safety rope of the worker, this implementation example is as follows: Figure 1 、 Figure 3 and Figure 4As shown, the first sleeve rod 2 of the power supply rod 1 is provided with a first ring rail sleeve 21, a first sliding block seat 22 and a first ring buckle 23; the first ring rail sleeve 21 is sleeved and installed on the telescopic joint of the first sleeve rod 2 and is located below the battery 33; the peripheral wall surface of the first ring rail sleeve 21 is provided with a first annular sliding rail 211, the first sliding block seat 22 is in sliding connection with the first annular sliding rail 211, and the first ring buckle 23 is buckled with the first sliding block seat 22; when the operating personnel need to be safely bound to the power supply rod 1, the fixed end rope buckle of the safety rope is detachably connected with the first ring buckle 23.

[0055] Further, the peripheral wall surface of the first ring rail sleeve 21 is provided with a plurality of first annular sliding rails 211, a plurality of first sliding block seats 22 are respectively in sliding connection with the plurality of first annular sliding rails 211, and a plurality of first ring buckles 23 are respectively buckled with the plurality of first sliding block seats 22, for simultaneously providing safety connection for a plurality of safety ropes.

[0056] In application, the operating personnel detachably buckle the fixed end rope buckle of the safety rope with the first ring buckle 23 on the power supply rod 1, and slide the first sliding block seat 22 on the first annular sliding rail 211, so that the hanging point of the safety rope can be flexibly adjusted according to the body position of the operating personnel; the structure utilizes the surrounding arrangement of the first ring rail sleeve 21 and the sliding rail to form a changeable hanging point of the safety rope in the circumferential range of the power supply rod 1, avoids the problem of too large angle or winding of the safety rope caused by the fixed hanging point, and thus ensures the operation convenience and safety of the operating personnel in different positions; the structure solves the deficiency of lack of temporary safety hanging point in the existing offshore operation, and effectively improves the personnel anti-falling protection capability.

[0057] In addition, a plurality of first annular sliding rails 211 are arranged on the first ring rail sleeve 21, and a plurality of first sliding block seats 22 and a plurality of first ring buckles 23 are matched, so that the simultaneous hanging of a plurality of safety ropes can be realized, the safety protection demand of multi-person cooperative operation can be met, or the safety ropes of the operating personnel and tools can be simultaneously buckled, and the overall construction safety is improved.

[0058] As shown in the foregoing connection structure of the measuring rod 4 and the safety connection of the safety rope of the operating personnel, Figure 2 、 Figure 3 and Figure 5 As shown, the second sleeve rod 5 of the measuring rod 4 is provided with a second ring rail sleeve 51, a second sliding block seat 52 and a second ring buckle 53; the second ring rail sleeve 51 is sleeved and installed on the telescopic joint of the second sleeve rod 5 and is located below the measuring unit 63; the peripheral wall surface of the second ring rail sleeve 51 is provided with a second annular sliding rail 511, the second sliding block seat 52 is in sliding connection with the second annular sliding rail 511, and the second ring buckle 53 is buckled with the second sliding block seat 52; when the operating personnel need to be safely bound to the measuring rod 4, the fixed end rope buckle of the safety rope is detachably connected with the second ring buckle 53.

[0062] The power supply rod 1 is provided with a rotatable wire reel 7, the input end of the wire reel 7 is electrically connected with the battery 33, the output end of the wire reel 7 can be extended with the rotation of the wire reel 7 and supply power for the measuring unit 63 of the side pull rod or the electronic equipment of the operator. Figures 1 to 3

[0063] The wire reel 7 is arranged between the first sleeve rod 2 top and the battery 33 or on the battery 33.

[0064] In application, the output wire 71 of the wire reel 7 on the power supply rod 1 is extended with the rotation of the wire reel 7 after starting, is separately connected with the measuring unit 63 of the measuring rod 4 or the second electric suction cup 62 for power supply, or is simultaneously connected with the measuring unit 63 and the second electric suction cup 62 for power supply, so that the measuring rod 4 can obtain stable power supply after being fixed at the measurement point.

[0068] In addition, the wire reel 7 can be designed as an automatic winding mechanism with limiting and buffering functions, which slows down the winding speed through a damping structure when quickly recovering, avoiding excessive tension or interface damage caused by rapid cable recovery.

[0069] Specifically, as Figure 2 and Figure 3 The measurement unit 63 is an RTK (Real-time kinematic) measurement device.

[0070] In application, the RTK (Real-Time Kinematic) measurement device is installed at the top of the measuring rod 4, and under the support of the connection of the battery 33 of the power supply rod 1 and the wire 71 of the wire reel 7, it can collect positioning data in real time and interact with the reference station signal to realize high-precision positioning at the centimeter level; the operator can quickly complete the structure point measurement through the measuring rod 4, avoiding the complex construction and fixed link of the traditional dependence on the measuring tower; this scheme not only improves the accuracy and efficiency of measurement, but also solves the problem of limited measurement point layout in the marine environment.

[0071] In addition, the RTK measurement device can combine with unmanned aerial vehicles or offshore buoys to form multi-source data interaction and build a temporary three-dimensional measurement network to meet the high-precision surveying and mapping needs of complex structures or large-scale construction.

[0072] The second embodiment of the offshore temporary positioning and fixing device is as follows Figure 1 and Figure 3As shown, the difference between this embodiment and the first embodiment lies in the specific cooperation structure of the first sleeve rod 2 and the first leg 31.

The wide end side of the plurality of first legs 31 is respectively rotationally connected with the plurality of first hinge blocks 261. A first thread 24 is arranged on the peripheral wall of the first sleeve rod 2, and a first lock ring sleeve 25 is threadedly connected to the first thread 24. The first lock ring sleeve 25 is arranged adjacent to the first mounting seat 26, and a plurality of pullable locks 8 corresponding to the first legs 31 are arranged on the first lock ring sleeve. When the first leg 31 is rotated to be retracted into the retracted state, the first lock ring sleeve 25 spirally rises away from the wide end side of the first leg 31 and stays at the narrow end side. The pullable lock 8 is pressed against the first leg 31, which is used to limit the rotational freedom of the first leg 31 and fix the retracted state of the first leg 31. When the first leg 31 is rotated to be lowered into the supporting state, the first lock ring sleeve 25 spirally descends to be close to and press the wide end side of the first leg 31, which is used to limit the rotational freedom of the first leg 31 and fix the supporting state of the first leg 31. After the first electric suction cup 32 is vacuum-suctioned to fix the power supply rod 1, the first leg 31 is converted from the retracted state to the supporting state under the unlocking of the pullable lock 8. The first leg 31 is rotated to be lowered to the concrete structure surface at the fixed point, and presses the first electric suction cup 32. The plurality of first legs 31 serve as radial reinforcing ribs to provide circumferential supporting force for the power supply rod 1 and radial pressing force for the first electric suction cup 32, so as to avoid the overturning of the power supply rod 1 and the air leakage of the first electric suction cup 32.

[0073] In the application, when the construction personnel fix the power supply rod 1, the power supply rod 1 is first erected on the concrete structure point, and the first electric suction cup 32 is started to realize preliminary suction and fixation. Then, the pullable lock 8 of the first lock ring sleeve 25 is unlocked, and the plurality of first legs 31 are rotated and lowered from the retracted state until they are supported on the concrete structure surface and press the first electric suction cup 32. The first lock ring sleeve 25 is rotated to spirally descend and press the wide end side of the first leg 31. At this time, the first leg 31 serves as a radial reinforcing rib to provide circumferential stable supporting force for the power supply rod 1, and simultaneously enhances the pressing and sealing effect of the electric suction cup, so as to avoid the overturning of the power supply rod 1 and the air leakage of the electric suction cup caused by wind or personnel shaking. The structure solves the problem of insufficient stability of the traditional single-point fixation through the triple fixation mode of “suction cup + multiple legs + lock ring sleeve pressing”, and significantly improves the stability and use safety of the power supply rod 1.

[0074] In addition, a non-slip rubber pad or a micro suction pad is additionally arranged at the bottom end of the first leg 31 to adapt to the wet and slippery or rough concrete surface, and further improve the supporting reliability.

[0075] Regarding the specific cooperation structure of the second sleeve rod 5 and the second leg 61, the embodiment isFigure 2 and Figure 3 As shown in the drawings, the bottom of the second sleeve rod 5 is connected with a second mounting seat 56, and a plurality of second hinge blocks 561 are arranged on the circumferential wall of the second mounting seat 56; the second electric suction cup 62 is connected to the bottom surface of the mounting seat; the wide end side of each of the plurality of second supporting legs 61 is rotationally connected with a corresponding second hinge block 561; a second thread 54 is arranged on the circumferential wall of the second sleeve rod 5, and a second lock ring sleeve 55 is threadedly connected to the second thread 54; the second lock ring sleeve 55 is arranged adjacent to the second mounting seat 56, and a plurality of pullable locks 8 corresponding to the second supporting legs 61 are arranged on the second lock ring sleeve; when the second supporting legs 61 are rotated to be retracted into the retracted state, the second lock ring sleeve 55 spirally rises away from the wide end side of the second supporting legs 61 and stays at the narrow end side, and the pullable locks 8 are pressed against the second supporting legs 61, so as to limit the rotational freedom of the second supporting legs 61 and fix the retracted state of the second supporting legs 61; when the second supporting legs 61 are rotated to be lowered into the supporting state, the second lock ring sleeve 55 spirally descends to be close to and press the wide end side of the second supporting legs 61, so as to limit the rotational freedom of the second supporting legs 61 and fix the supporting state of the second supporting legs 61; after the second electric suction cup 62 is vacuum-suctioned to fix the measuring rod 4, the second supporting legs 61 are switched from the retracted state to the supporting state under the unlocking of the pullable locks 8, the second supporting legs 61 are rotated to be lowered to the concrete structure surface at the measuring point, and the second electric suction cup 62 is pressed; the plurality of second supporting legs 61 serve as radial reinforcing ribs, so as to provide circumferential supporting force for the measuring rod 4 and radial pressing force for the second electric suction cup 62, thereby avoiding overturning of the measuring rod 4 and air leakage of the second electric suction cup 62.

[0076] In the application, the measurer first stands the measuring rod 4 at the target measuring point, starts the second electric suction cup 62 to firmly suction the second electric suction cup 62 to the concrete surface, then unlocks the pullable locks 8 of the second lock ring sleeve 55, drives the plurality of second supporting legs 61 to be switched from the retracted state to the supporting state, presses the second electric suction cup 62 and the concrete structure surface, and rotates the second lock ring sleeve 55 to spirally descend and lock the second supporting legs 61, so as to form the circumferential radial supporting force for the measuring rod 4.

[0077] The plurality of second supporting legs 61 and the electric suction cup cooperatively enable the measuring rod 4 to maintain a stable vertical state, so as to avoid tilting or suction failure caused by wind or personnel pulling; the structure effectively solves the problems of unstable temporary measuring point arrangement and easily disturbed measuring accuracy on the sea, and guarantees reliable operation of high-precision positioning instruments (such as RTK).

[0078] In addition, a fine adjustment supporting pad or a self-adaptive buffer unit is arranged at the bottom end of the second supporting leg 61 of the measuring rod 4, so as to adapt to different slopes or uneven concrete surfaces, so as to ensure the perpendicularity of the measuring rod 4.

[0079] Any technical features in the above embodiments can be combined, and for the sake of brevity, not all possible combinations are described.
