Description

Technical Field

[0001] This invention relates to the field of port and waterway construction technology, and in particular to a temporary positioning and fixing device for marine applications. Background Technology

[0002] In port and waterway engineering construction, the positioning and fixing of large prefabricated components at sea has always been a critical step. Traditional methods often rely on installing measuring towers or pre-drilling holes in the components, drilling and installing reinforcing bars, and then fixing them at these points with bolts. While these methods offer strong stability, they also have significant limitations: on the one hand, additional pre-drilling or destructive construction must be carried out on the prefabricated structure, increasing the number of procedures and costs; on the other hand, point fixing is a rigid method, making it difficult to adjust flexibly and failing to meet the needs of temporary positioning and repeated use at sea.

[0003] During construction operations, safety protection is particularly prominent due to the unique nature of the marine environment. Currently, the commonly used safety measures are limited to wearing life jackets. However, when working on or off structures, crossing or measuring, there is a lack of temporary support points for attaching safety belts, which can easily lead to operational risks. At the same time, the marine working environment is characterized by large waves, and the surfaces of construction platforms and components are often slippery, undulating, or swaying, resulting in poor stability for personnel and significantly increasing the difficulty of construction operations. Existing safety protection measures are insufficient and cannot provide reliable temporary protection points for construction personnel.

[0004] Currently, structural fixing is usually achieved through hard connections such as bolts and steel bars. However, this method is not only complex and inflexible, but also often cannot be quickly disassembled and reused after completion, which is not conducive to temporary positioning and the relocation of construction measurement points. Especially when multi-point measurement and dynamic positioning are involved, the existing methods cannot efficiently respond to construction needs.

[0005] In summary, the existing technology has at least the following technical problems: In existing port and waterway engineering construction, there are technical problems such as the high degree of destructiveness and lack of flexibility in component positioning, insufficient safety protection for construction personnel, and difficulty in meeting the needs of temporary positioning and mobile measurement. Summary of the Invention

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] The specific implementation provides a temporary positioning and fixing device for marine applications. This device includes a power supply rod and a measuring rod. The power supply rod consists of a retractable first rod, a first leg, a first electric suction cup, and a battery. The measuring rod consists of a retractable second rod, a second leg, a second electric suction cup, and a measuring unit. The electric suction cup and the leg are combined to achieve adhesion and wind-resistant, tensile-resistant, and anti-overturning fixing on concrete structural surfaces. The battery powers the electric suction cup and the measuring unit. The power supply rod is fixed at the point to be fixed, and the measuring rod is fixed at the point to be measured as a safety rope attachment point. This allows the device to achieve non-destructive temporary fixing during marine construction, providing safety protection points for workers and flexibly deploying temporary measuring points. It effectively solves the technical problems in existing port and waterway engineering construction, such as highly destructive component positioning, lack of flexibility, insufficient safety protection for construction personnel, and difficulty in meeting the needs of temporary positioning and mobile measurement.

[0030] The first implementation of a temporary positioning and fixing device at sea, for example Figures 1 to 3As shown, the device includes a power supply rod 1 and a measuring rod 4. The power supply rod 1 includes a retractable first sleeve rod 2, first support legs 31, a first electric suction cup 32, and a battery 33. The battery 33 is installed on the top of the first sleeve rod 2, the first electric suction cup 32 is installed on the bottom of the first sleeve rod 2, and multiple first support legs 31 are installed on the bottom peripheral wall of the first sleeve rod 2, covering the first electric suction cup 32. The first electric suction cup 32 is electrically connected to the battery 33. The measuring rod 4 includes a retractable second sleeve rod 5, second support legs 61, a second electric suction cup 62, and a measuring unit 63. The measuring unit 63 is installed on the top of the second sleeve rod 5, and the second electric suction cup 62 is installed on... At the bottom of the second rod 5, multiple second legs 61 are installed on the bottom periphery of the second rod 5 and cover the second electric suction cup 62; the second electric suction cup 62, the measuring unit 63 and the storage battery 33 are electrically connected; the power supply rod 1 is set on the concrete structure surface of the point to be fixed by the first leg 31 and the first electric suction cup 32, and then the storage battery 33 supplies power to the second electric suction cup 62 to cooperate with the second leg 61 to set the measuring rod 4 on the concrete structure surface of the point to be measured; the safety rope of the operator is attached to the power supply rod 1 or the measuring rod 4 to provide safety protection for the operator's construction operation and measurement movement on the marine concrete structure.

[0031] In this process, after cleaning the concrete surface of the point to be fixed, the power supply pole 1 is erected at the fixed point and the first electric suction cup 32 is started. After the first electric suction cup 32 reaches the required vacuum level and automatically stops venting, sealant is applied to the outer contour of the suction cup of the first electric suction cup 32 to seal the negative pressure space of the first electric suction cup 32. After the operator connects the safety rope to the power supply pole 1, he moves to the measurement point, cleans the concrete surface of the measurement point, erects the measuring pole 4 at the measurement point, and starts the second electric suction cup 62. After the second electric suction cup 62 reaches the required vacuum level and automatically stops venting, sealant is applied to the outer contour of the suction cup of the second electric suction cup 62 to seal the negative pressure space of the second electric suction cup 62.

[0032] Specifically, the offshore temporary positioning and fixing device addresses the technical problems of high destructiveness, insufficient flexibility, and lack of safety protection for workers in existing port and waterway construction. It proposes a technical solution that is rapid to deploy, reliably fixed, and takes into account safety protection, and has several technical advantages: it achieves non-destructive fixing and improves flexibility; by setting up a combination of electric suction cups and outriggers, it can be directly adsorbed and fixed on the concrete structure surface, and has wind and tensile strength characteristics, eliminating the need for pre-drilled holes or rebar installation, thus avoiding damage to precast components; at the same time, the device can be disassembled and moved at any time, enabling rapid deployment at multiple points, greatly improving the flexibility and adaptability of construction surveying.

[0033] Provides temporary safety protection to ensure operational safety; the power supply pole 1 and measuring pole 4 are not only used as positioning and measuring devices, but also as attachment points for workers' safety belts; through the power supply of battery 33 and the negative pressure adsorption of electric suction cups, as well as the wind and tensile strength provided by the outriggers, a stable temporary support point is formed, which effectively solves the problem of lacking reliable safety attachment points during offshore operations, and provides fall protection for construction workers when moving, operating and measuring on offshore concrete structures.

[0034] Self-powered capability, adaptable to marine environment; a storage battery 33 is installed on the power supply pole 1 to provide power to the electric suction cup and the measuring unit 63, avoiding the inconvenience and risks caused by external ship power supply and floating wiring at sea, ensuring the independent operation capability of the device in marine environment, and improving the reliability and convenience of use.

[0035] Improved stability and sealing: After the electric suction cup reaches the required vacuum level and automatically stops venting, sealant is applied to its outer contour to further seal the negative pressure space, enhancing the durability of the adsorption effect and the ability to resist wind and wave interference, thus meeting the stable operation requirements in high humidity and turbulent marine environments.

[0036] The positioning and measurement functions are integrated; the power supply pole 1 and the measuring pole 4 work together to meet the triple requirements of fixing, protection and measurement, forming an integrated temporary positioning and measurement system; the power supply pole 1 and the measuring pole 4 achieve the synergistic effect of positioning and measurement during construction, reduce additional deployment steps, and improve the efficiency and safety of construction measurement.

[0037] In summary, this technical solution addresses the problems of insufficient flexibility, lack of safety protection, and difficulty in setting up temporary marine measurement points in existing port and waterway engineering construction technologies through non-destructive fixing methods, provision of safety protection points, self-powered capability, highly reliable adsorption structure, and wind- and tensile-resistant circumferential support structure design. It has practical value and promising prospects for promotion.

[0038] As one alternative implementation method: Regarding the connection structure for the safe connection between the aforementioned power pole 1 and the worker's safety rope, this embodiment is, for example... Figure 1 , Figure 3 and Figure 4 As shown, the first sleeve 2 of the power supply pole 1 is provided with a first ring rail sleeve 21, a first slider 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 pole 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 slide rail 211, the first slider seat 22 is slidably connected to the first annular slide rail 211, and the first ring buckle 23 is fastened to the first slider seat 22; when the operator needs to be safely tied to the power supply pole 1, the fixed end of the safety rope is detachably connected to the first ring buckle 23.

[0039] Furthermore, the peripheral wall surface of the first ring rail sleeve 21 is provided with multiple ring-shaped slide rails 211, multiple first slider seats 22 are slidably connected to the multiple ring-shaped slide rails 211 respectively, and multiple first ring buckles 23 are buckled to the multiple first slider seats 22 respectively, for providing a safe connection for multiple safety ropes at the same time.

[0040] In application, the worker detachably fastens the fixed end of their safety rope to the first ring buckle 23 on the power supply pole 1. The rope then slides along the first annular slide rail 211 via the first slider seat 22, allowing the safety rope's attachment point to be flexibly adjusted according to the worker's body position. This structure utilizes the circumferential arrangement of the first annular slide rail 211 and the slide rail to create variable attachment points for the safety rope within the circumference of the power supply pole 1, avoiding problems such as excessively large angles or tangling caused by fixed attachment points. This ensures the worker's operational convenience and safety when working in different locations. This structure addresses the lack of temporary safety attachment points in existing offshore operations, effectively improving personnel fall protection capabilities.

[0041] In addition, multiple rings of first annular slide rails 211 are arranged on the first ring rail sleeve 21, and multiple first slide blocks 22 and multiple first ring buckles 23 are used to realize the simultaneous attachment of multiple safety ropes, meet the safety protection needs of multiple people working together, or be used to attach the safety ropes of workers and tools at the same time, thereby improving the overall construction safety.

[0042] Regarding the connection structure between the aforementioned measuring rod 4 and the worker's safety rope, this implementation is as follows: Figure 2 , Figure 3 and Figure 5 As shown, the second sleeve 5 of the measuring rod 4 is provided with a second ring rail sleeve 51, a second slider 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 slide rail 511, the second slider seat 52 is slidably connected to the second annular slide rail 511, and the second ring buckle 53 is fastened to the second slider seat 52; when the operator needs to be safely tied to the measuring rod 4, the fixed end of the safety rope is detachably connected to the second ring buckle 53.

[0043] Furthermore, the peripheral wall surface of the second ring rail sleeve 51 is provided with multiple rings of second ring slide rails 511, multiple second slider seats 52 are slidably connected to the multiple rings of second ring slide rails 511 respectively, and multiple second ring buckles 53 are buckled to the multiple second slider seats 52 respectively, for providing a safe connection for multiple safety ropes at the same time.

[0044] In application, the operator attaches the fixed end of the safety rope to the second ring buckle 53 of the measuring rod 4, and the second slider seat 52 slides on the second annular slide rail 511, so that the attachment point can be adjusted within the circumferential range of the measuring rod 4 to adapt to the movement needs of different operators. This scheme provides the operator with a stable safety protection point during measurement operations, avoiding restrictions on personnel movement due to the fixed position of the measuring rod 4. Through the dual-point attachment of the measuring rod 4 and the power supply rod 1, a redundant safety system is formed, enhancing the overall safety and reliability of the operation.

[0045] In addition, the second ring rail sleeve 51 is equipped with multiple ring rails 511 and multiple second slider seats 52 and second ring buckles 53, which can provide safety attachment points for multiple surveyors at the same time, or be extended to attach instrument anti-fall ropes to ensure the safe use of surveying equipment in marine environments.

[0046] Regarding the electrical connection between the battery 33 of the power supply rod 1 and the measuring unit 63 and the second electric suction cup 62 of the measuring rod 4, this embodiment is, for example... Figures 1 to 3 As shown, a rotatable coil 7 is installed on the power supply pole 1. The input end of the coil 7 is electrically connected to the storage battery 33, and the output end of the coil 7 extends out as the coil 7 rotates and supplies power to the measuring unit 63 of the side pull rod or the electronic equipment of the operator.

[0047] The coil 7 is installed between the top of the first rod 2 and the battery 33 or on the battery 33.

[0048] When in use, after the power supply rod 1 is started, the output wire 71 on the reel 7 extends out with the rotation of the reel 7, and is connected to the measuring unit 63 or the second electric suction cup 62 of the measuring rod 4 for power supply, or is connected to the measuring unit 63 and the second electric suction cup 62 for power supply at the same time, so that the measuring rod 4 can obtain a stable power supply after being fixed at the measuring point. This structure uses the storage battery 33 for centralized power supply, avoiding the cumbersome and dangerous layout of external power supply, and solving the problem of inconvenient power supply in the marine environment. At the same time, the rotating and telescopic design of the reel 7 ensures that the wire 71 will not get tangled or dragged during the release and retraction process, improving the convenience of operation and the reliability of power connection.

[0049] In addition to powering the measuring unit 63 and the suction cup, the cable reel 7 can also power the portable electronic devices of the operators (such as handheld rangefinders and communication terminals) to extend the equipment's battery life and improve the efficiency of on-site construction and measurement.

[0050] Furthermore, to facilitate the retraction of the output end of the spool 7, the spool 7 has an automatic retraction function; the spool 7 is equipped with a spiral spring inside for driving the rotation of the spool 7; the spiral spring stores energy when the output end of the spool 7 is pulled out, and provides rotational power for the automatic retraction rotation of the spool 7 when the output end of the spool 7 is retracted.

[0051] In application, the reel 7 is equipped with a ratchet mechanism that works in conjunction with a spiral spring. When the wire 71 needs to be pulled out, it can be pulled out directly. When the wire 71 needs to stop pulling out or needs to be stationary, the ratchet mechanism restricts the spiral spring from providing power for the rotation of the reel 7, allowing the output end of the wire 71 to operate without traction. When the operator finishes using the device or needs to move the measuring point, the ratchet mechanism of the reel 7 is released, and the internal spiral spring provides rotational power, automatically retracting the output end of the wire 71 back into the reel 7. This structural design avoids the complicated operation of manual wire reeling, making the wire reeling process simple and efficient, while reducing the risk of wear and entanglement of the wire 71 exposed to the wet and slippery marine environment. It effectively solves the problem of difficult cable management and ensures the durability and reusability of the device.

[0052] In addition, the cable reel 7 can also be designed as an automatic cable reeling mechanism with limit and buffer functions. During rapid cable reeling, the damping structure slows down the reeling speed to avoid excessive tension or damage to the interface caused by rapid cable reeling.

[0053] Specifically, such as Figure 2 and Figure 3 Measurement unit 63 is an RTK (Real-time kinematic) measuring instrument.

[0054] When applied, the RTK (Real-Time Kinematic) measuring instrument is installed on the top of the measuring rod 4. With the support of the battery 33 of the power supply rod 1 and the wire 71 of the line reel 7, it can collect positioning data in real time and link with the base station signal to achieve centimeter-level high-precision positioning. The operators can quickly complete the structural point measurement through the measuring rod 4, avoiding the complicated construction and fixing process of the traditional method that relies on measuring towers. This solution not only improves the accuracy and efficiency of measurement, but also solves the problem of limited measurement point deployment in the marine environment.

[0055] In addition, RTK surveyors, combined with UAVs or marine buoys, form multi-source data interaction and construct temporary three-dimensional measurement networks to meet the high-precision mapping needs of complex structures or large-scale construction.

[0056] A second implementation of a temporary positioning and fixing device at sea, for example Figure 1 and Figure 3As shown, the difference between this embodiment and the first embodiment lies in the specific cooperation structure between the first sleeve rod 2 and the first support leg 31. The bottom of the first sleeve rod 2 is connected to a first mounting base 26, and the peripheral wall of the first mounting base 26 is provided with multiple first hinge blocks 261. A first electric suction cup 32 is connected to the bottom surface of the mounting base. The wide ends of the multiple first support legs 31 are respectively rotatably hinged to the multiple first hinge blocks 261. The peripheral wall of the first sleeve rod 2 is provided with a first thread 24, and a first locking ring sleeve 25 is threaded onto the first thread 24. The first locking ring sleeve 25 is arranged adjacent to the first mounting base 26, and multiple leverable latches 8 are arranged on the first locking ring sleeve corresponding to the first support leg 31. When the first support leg 31 rotates and retracts into the retracted state, the first locking ring sleeve 25 spirals upward away from the wide end of the first support leg 31 and stops at the narrow end. The lever 8 presses against the first support leg 31 to restrict the rotational freedom of the first support leg 31 and fix the first support leg 31 in the retracted state; when the first support leg 31 rotates down to enter the supporting state, the first locking ring 25 spirals down to approach and press against the wide end side of the first support leg 31 to restrict the rotational freedom of the first support leg 31 and fix the first support leg 31 in the supporting state; after the first electric suction cup 32 vacuum adsorbs and fixes the power supply rod 1, the first support leg 31 changes from the retracted state to the supporting state when the lever 8 is unlocked, the first support leg 31 rotates down to the concrete structure surface of the fixed point, and presses against the first electric suction cup 32; multiple first support legs 31 act as radial reinforcing ribs to provide circumferential support force for the power supply rod 1 and radial clamping force for the first electric suction cup 32, preventing the power supply rod 1 from tipping over and the first electric suction cup 32 from leaking air.

[0057] When applying this method, construction workers first place the power supply pole 1 on the concrete structure and activate the first electric suction cup 32 to achieve initial suction and fixation. Then, they unlock the lever lock 8 of the first locking ring 25, and multiple first legs 31 rotate and lower from the retracted state until they support the concrete structure surface and press down on the first electric suction cup 32. The first locking ring 25 is then rotated to spiral down and press the wide end of the first legs 31. At this time, the first legs 31 act as radial reinforcing ribs, providing circumferential stable support for the power supply pole 1, while enhancing the pressing and sealing effect of the electric suction cup, preventing the power supply pole 1 from tipping over or the electric suction cup from leaking and failing due to wind, waves, or personnel movement. This structure, through the triple fixing method of "suction cup + multiple legs + locking ring pressing", effectively solves the problem of insufficient stability of traditional single-point fixing, and significantly improves the stability and safety of the power supply pole 1.

[0058] In addition, anti-slip pads or micro-adhesive pads are added to the bottom of the first leg 31 to adapt to wet or rough concrete surfaces, further improving the reliability of the support.

[0059] Regarding the specific mating structure between the second rod 5 and the second support leg 61, this embodiment is as follows: Figure 2 and Figure 3 As shown, the bottom of the second sleeve rod 5 is connected to a second mounting base 56, and the peripheral wall of the second mounting base 56 is provided with a plurality of second hinge blocks 561; the second electric suction cup 62 is connected to the bottom surface of the mounting base; the wide ends of the plurality of second legs 61 are respectively rotatably hinged to the plurality of second hinge blocks 561; the peripheral wall of the second sleeve rod 5 is provided with a second thread 54, and a second locking ring sleeve 55 is threadedly connected to the second thread 54. The second locking ring sleeve 55 is arranged adjacent to the second mounting base 56, and a plurality of leverable latches 8 are provided on the second locking ring sleeve corresponding to the second legs 61; when the second legs 61 rotate and retract into the retracted state, the second locking ring sleeve 55 spirals upward away from the wide end of the second legs 61 and stops at the narrow end, and the leverable latches 8 press against the second legs 61 to limit the second legs 61. The rotational freedom of the two legs 61 is limited and the retracted state of the second legs 61 is fixed. When the second legs 61 rotate and lower into the supporting state, the second locking ring 55 spirals down and approaches and presses against the wide end of the second legs 61 to limit the rotational freedom of the second legs 61 and fix the supporting state of the second legs 61. After the second electric suction cup 62 vacuum adsorbs and fixes the measuring rod 4, the second legs 61 change from the retracted state to the supporting state under the unlocking of the lever lock 8. The second legs 61 rotate and lower to the concrete structure surface of the measuring point and press against the second electric suction cup 62. Multiple second legs 61 act as radial reinforcing ribs to provide circumferential support force for the measuring rod 4 and radial clamping force for the second electric suction cup 62, preventing the measuring rod 4 from tipping over and the second electric suction cup 62 from leaking air.

[0060] When applying the method, the surveyor first places the measuring rod 4 at the target measurement point and activates the second electric suction cup 62 to firmly attach it to the concrete surface. Then, the lever lock 8 of the second locking ring 55 is unlocked, driving multiple second legs 61 to rotate and lower from the retracted state to the supporting state, pressing them against the second electric suction cup 62 and the concrete structure surface. The second locking ring 55 is then rotated to spiral down and lock the second legs 61, thereby forming a circumferential radial support force for the measuring rod 4.

[0061] Among them, multiple second legs 61 work together with electric suction cups to keep the measuring rod 4 in a stable vertical position, avoiding tilting or suction failure due to wind, waves or personnel pulling. This structure effectively solves the problems of unstable deployment of temporary measurement points at sea and easy interference with measurement accuracy, ensuring the reliable operation of high-precision positioning instruments (such as RTK).

[0062] In addition, a fine-tuning support pad or adaptive buffer unit is added to the bottom of the second leg 61 of the measuring rod 4 to adapt to different slopes or uneven concrete surfaces, so as to ensure the verticality of the measuring rod 4.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
