Description

Technical Field

[0001] This invention relates to the field of hoisting technology, specifically to a hoisting device and method for power grid infrastructure construction. Background Technology

[0002] Offshore platform-based observation stations are crucial infrastructure for marine hydrological and meteorological observation, automatically acquiring marine environmental data, including marine meteorological and hydrological elements. Furthermore, they monitor marine ecosystems. Offshore platform-based observation stations play an irreplaceable role in marine scientific research, disaster early warning, environmental protection, and resource management, forming an essential component of the modern marine observation system. The construction of offshore platform-based observation stations requires the development and upgrading of power grid infrastructure, including power generation, transmission, transformation, distribution, and consumption facilities, to meet the power requirements of the station's monitoring equipment and ensure its normal operation. During power grid infrastructure construction, hoisting equipment can be used to lift large equipment, materials, and components, reducing the time and physical exertion of manual handling and thus accelerating the construction progress.

[0003] CN118495369A discloses a hoisting buffer device for power grid infrastructure construction. It solves the technical problem that the lack of buffering function during the hoisting of infrastructure facilities during power grid construction easily damages the facilities and affects their use. It has the technical effect of buffering the facilities during hoisting, preventing damage, protecting them intact, and facilitating installation.

[0004] Based on existing technologies, the following problems exist:

[0005] While the aforementioned application documents can buffer the hoisted facilities and reduce damage during transport, existing hoisting devices used for offshore platform-based observation stations are susceptible to problems during power grid infrastructure construction. Large waves at sea affect the stability of the hoisting devices, influencing their lifting and lowering positions and thus hoisting efficiency. Furthermore, since hoisting devices typically use cables, they are easily affected by sea winds, causing swaying or even falls, which can damage power grid infrastructure equipment and pose safety hazards, thus hindering the construction of power grid infrastructure and, consequently, the construction of offshore platform-based observation stations. Therefore, this paper proposes a hoisting device and method for power grid infrastructure construction to address these issues. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention provides a hoisting device and method for power grid infrastructure construction. When constructing offshore platform-based observation stations, the hoisting device is less affected by sea waves, the stability of the hoisting device during lifting and lowering is increased, and the impact on power grid infrastructure construction is reduced, thereby reducing the impact on the construction of offshore platform-based observation stations.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a hoisting device for power grid infrastructure construction, comprising a pulley mechanism disposed on the outside of the lifting arm, a first connecting seat disposed at the bottom of the pulley mechanism, a second connecting seat disposed at the bottom of the first connecting seat, and a hoisting basket disposed at the bottom of the second connecting seat. The second connecting seat has first limiting mechanisms on both sides for clamping the hoisting basket. A connecting assembly is disposed on the top of the hoisting basket, and second limiting mechanisms cooperating with the first limiting mechanisms are disposed on both sides of the connecting assembly to limit the swaying of the hoisting basket. The first limiting mechanism includes:

[0008] The limiting arms are rotatably mounted on both sides of the second connecting seat and are arranged at intervals. The top of the second connecting seat is provided with a drive mechanism for driving the limiting arms to rotate. The bottom of the limiting arms is designed in a bent shape, and the bent part of the bottom of the limiting arms is provided with a first contact surface and a second contact surface. The two limiting arms located on the same side of the second connecting seat are provided with a buckling mechanism on the side that is far away from each other.

[0009] The second limiting mechanism includes:

[0010] Limiting seats are located on both sides of the connecting assembly. The sides of the limiting seats that are far apart from each other are designed to be concave to form a third contact surface and a fourth contact surface that abut against the first contact surface and the second contact surface, respectively, so that the limiting arm clamps and fixes the limiting seat. The inner side of the limiting seat is provided with an auxiliary mechanism that cooperates with the buckling mechanism.

[0011] Furthermore, the latching mechanism includes:

[0012] A hydraulic rod is fixedly mounted on the bottom side wall of the limiting arm, and a limiting component is fixedly sleeved on the side wall of the hydraulic rod's telescopic shaft. A guide rod that passes through the limiting arm is fixedly mounted on the side wall of the limiting component. A guide hole for sleeved guide rod is opened on the side wall of the limiting arm. The telescopic shaft of the hydraulic rod drives the guide rod to move along the guide hole to limit the movement of the hydraulic rod's telescopic shaft.

[0013] Furthermore, the second limiting mechanism also includes:

[0014] A frame is fixedly disposed on both sides of the recessed area of ​​the limiting seat, so that a cavity is formed between the frame and the recessed area of ​​the limiting seat, and the auxiliary mechanism includes the following within the cavity:

[0015] The mounting base is fixedly installed inside the limiting seat and located in the cavity. A pressure sensor is fixedly installed on the side of the mounting base near the limiting arm. A housing extending outside the limiting seat is fitted on the side wall of the mounting base, and the housing is fitted on the outside of the pressure sensor. A stop plate is fixedly installed on the side of the housing near the limiting arm.

[0016] A limiting ring is fixedly installed on the inner side of the limiting seat, and the inner wall of the limiting ring is sleeved on the outer wall of the housing. The inner wall diameter of the limiting ring is smaller than the side wall diameter of the abutment plate, so as to limit the movement of the housing.

[0017] Furthermore, the auxiliary mechanism also includes:

[0018] The first movable through groove is opened on the side wall of the mounting base and arranged in a circular array with the center point of the mounting base. The first movable through groove extends to the outside of the limiting seat.

[0019] The second movable channel is opened on the side wall of the housing and arranged in a circular array with the center point of the housing. The second movable channel and the first movable channel are arranged alternately so that the side wall of the housing is fitted into the first movable channel, thereby allowing the housing to move along the first movable channel.

[0020] Furthermore, the connection component includes:

[0021] The connecting arm is fixedly mounted on the top of the suspended basket at the center point of the basket. A base plate is fixedly mounted on the top of the connecting arm. The sides of the limiting seats that are close to each other are fixedly connected to the two sides of the base plate.

[0022] Furthermore, the drive mechanism includes:

[0023] A support base is fixedly installed at the bottom of the second connecting base and symmetrically arranged around the center point of the second connecting base. A rotating base is fixedly installed on the outer side of the support base. The outer side of the rotating base is rotatably connected to the top of the limiting arm. A rotating rod is rotatably installed on the outer side of the rotating base, and the side wall of the rotating rod is fixedly connected to the top of the limiting arm. The two rotating rods are connected by a first transmission mechanism so that the two rotating rods rotate synchronously and in opposite directions, thereby causing the limiting arms on both sides of the second connecting base to rotate closer to each other or further away from each other along the rotating rods.

[0024] The servo motor is fixedly mounted on the top of the second connecting base, and the output shaft of the servo motor is connected to one of the rotating rods through the second transmission mechanism.

[0025] Furthermore, a first hoisting mechanism is provided at the bottom of the first connecting seat to drive the second connecting seat to rise and fall. Third limiting mechanisms are provided on both sides of the first connecting seat to limit the rising and falling of the second connecting seat. The third limiting mechanisms include:

[0026] The first ear plate is fixedly disposed on both sides of the first connecting seat;

[0027] The second ear plate is fixedly installed on both sides of the second connecting seat. The positioning rod is located on both sides of the lifting arm through the first ear plate and the second ear plate. The top of the second ear plate is fixedly provided with a positioning rod that passes through the first ear plate. The top of the first ear plate is provided with a positioning hole for the positioning rod.

[0028] A limiting block is fixedly installed on the top of the positioning rod, and the side wall diameter of the limiting block is larger than the inner wall diameter of the positioning hole, so as to prevent the positioning rod from disengaging from the positioning hole.

[0029] Furthermore, the first hoisting mechanism includes:

[0030] The first winch is fixedly installed at the bottom of the first connecting seat. The bottom of the cable of the first winch is fixedly provided with a first hook. The first hook is connected to the lifting lug on the top of the second connecting seat to raise and lower the second connecting seat.

[0031] Furthermore, the bottom of the second connecting seat is provided with a second hoisting mechanism for raising and lowering the suspended platform, the second hoisting mechanism including:

[0032] The second winch is fixedly installed at the bottom of the second connecting seat. The bottom of the cable of the second winch is fixedly provided with a second hook. The second hook is connected to the lifting lug on the top of the base plate to lift the basket.

[0033] This invention also provides a method for using a hoisting device for power grid infrastructure construction. The method, employing the aforementioned hoisting device, includes the following steps:

[0034] S1: Place the power grid infrastructure to be hoisted into the basket, and then lift the basket to move the power grid infrastructure to the designated location;

[0035] S2: During the hoisting process, if the suspended platform shakes significantly, the platform will be lifted to its highest position. Then, the first and second limiting mechanisms will work together to clamp and fix the platform. Furthermore, the platform will be further secured by the buckle mechanism and auxiliary components to limit the platform's violent shaking.

[0036] This invention provides a hoisting device and method for power grid infrastructure construction. Compared with the prior art, it has the following advantages:

[0037] 1. This invention, through the cooperation of the first and second limiting mechanisms, facilitates the clamping and limiting of the suspended basket after violent shaking, thereby improving the stability of the suspended basket. After the suspended basket is limited by the first and second limiting mechanisms, the locking mechanism and auxiliary mechanism work together to prevent the suspended basket from shifting laterally after being limited, further improving stability. The third limiting mechanism and the first hoisting mechanism allow the height of the suspended basket to be adjusted after it is clamped and limited, so as to move the suspended basket and the power grid infrastructure inside the suspended basket to a designated location, thereby facilitating the construction of offshore platform-based observation stations.

[0038] 2. In this invention, the first limiting mechanism and the second limiting mechanism work together to move the basket to the highest position after it sways. At this time, the concave part of the limiting seat is located in the fitting position after the limiting arm rotates. Then, the driving mechanism drives the limiting arm of the first limiting mechanism to embed into the concave part of the limiting seat to clamp and fix the limiting seat, thereby limiting the basket and reducing its sway.

[0039] By making the first and second contact surfaces contact the third and fourth contact surfaces respectively, the stability of the engagement between the limiting arm and the limiting seat is improved, and the detachment of the limiting arm from the limiting seat is avoided, thus facilitating multiple limiting uses.

[0040] By designing the sides of the limiting seats that are far apart to be concave, the distance between the concave part of the limiting seat and the two side frames is greater than the width of the limiting arm, thus facilitating the smooth entry of the limiting arm into the concave part of the limiting seat.

[0041] 3. The present invention uses a buckle mechanism and auxiliary components to limit the lateral movement of the suspended platform after the first and second limiting mechanisms work together to limit the platform, thereby further improving the stability of the suspended platform. In addition, the pressure sensor facilitates the monitoring of the degree of compression of the hydraulic rod on the shell, and avoids the hydraulic rod limiting the limiting seat from both sides of the limiting arm when the position of the limiting arm entering the limiting seat is not in the center, i.e., the blank space on both sides of the limiting arm is not uniform.

[0042] 4. The present invention uses a first hoisting mechanism and a third limiting mechanism to limit the basket after the first and second limiting mechanisms have been used, and then the basket can be controlled to move down a certain height, so that the basket can be placed in a designated position to facilitate power grid infrastructure construction. Moreover, during movement, the positioning rod and positioning hole work together to avoid connecting the second connecting seat only through the cable of the first hoisting mechanism, thereby improving the stability of the basket movement.

[0064] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] Example 1: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A hoisting device for power grid infrastructure construction includes a pulley mechanism 1 located on the outside of the lifting boom. The pulley mechanism 1 typically moves horizontally along the lifting boom of the crane tower to adjust the horizontal position of the suspended platform 7. Figure 15 The pulley mechanism 1 is existing technology and will not be described in detail here. It also includes a first connecting seat 2 located at the bottom of the pulley mechanism 1, a second connecting seat 5 vertically mounted at the bottom of the first connecting seat 2, and a suspended basket 7 vertically mounted at the bottom of the second connecting seat 5. The second connecting seat 5 has first limiting mechanisms 6 on both sides for clamping the suspended basket 7. A connecting component 9 is located at the top of the suspended basket 7. Second limiting mechanisms 8, cooperating with the first limiting mechanisms 6, are located on both sides of the connecting component 9 to limit the swaying of the suspended basket 7. The first limiting mechanism 6 includes:

[0066] Limiting arms 61 are rotatably disposed on both sides of the second connecting seat 5 and are arranged at intervals. The top of the second connecting seat 5 is provided with a driving mechanism 11 for driving the limiting arms 61 to rotate. The bottom of the limiting arms 61 is designed in a bent shape, and the bent part at the bottom of the limiting arms 61 is provided with a first contact surface 62 and a second contact surface 63. The two limiting arms 61 located on the same side of the second connecting seat 5 are provided with a buckling mechanism 64 on the side that is far away from each other.

[0067] The second limiting mechanism 8 includes:

[0068] Limiting seats 81 are disposed on both sides of the connecting component 9. The sides of the limiting seats 81 that are far apart from each other are designed to be concave to form a third contact surface 84 and a fourth contact surface 83 that abut against the first contact surface 62 and the second contact surface 63 respectively, so that the limiting arm 61 clamps and fixes the limiting seat 81. The inner side of the limiting seat 81 is provided with an auxiliary mechanism 85 that cooperates with the buckling mechanism 64.

[0069] In practical implementation, when the hoisting basket 7 experiences violent shaking during the hoisting process via the first hoisting mechanism 4, the first winch of the first hoisting mechanism 4 is fully wound up to bring the base plate 91 close to the second connecting seat 5. Then, the driving mechanism 11 drives the limiting arm 61 to rotate, so that the bent part at the bottom of the limiting arm 61 is embedded in the limiting seat 81. That is, the first contact surface 62 and the second contact surface 63 respectively contact and abut against the third contact surface 84 and the fourth contact surface 83, so that the limiting arm 61 clamps and fixes the limiting seat 81, thereby limiting the basket 7 and preventing the basket 7 from being connected only by the cable of the second hoisting mechanism 10, thus improving the stability of the basket 7.

[0070] By designing the sides of the limiting seats 81 that are far apart to be concave, the distance between the concave portion of the limiting seats 81 and the two side frames 82 is greater than the width of the limiting arms 61, thus facilitating the smooth entry of the limiting arms 61 into the concave portion of the limiting seats 81.

[0071] Please see Figure 5 The locking mechanism 64 includes:

[0072] A hydraulic rod 642 is fixedly mounted on the bottom side wall of the limiting arm 61, and a limiting member is fixedly sleeved on the side wall of the telescopic shaft of the hydraulic rod 642. A guide rod 641 that passes through the limiting arm 61 is fixedly mounted on the side wall of the limiting member. A guide hole for sleeved guide rod 641 is opened on the side wall of the limiting arm 61. The telescopic shaft of the hydraulic rod 642 drives the guide rod 641 to move along the guide hole to limit the movement of the telescopic shaft of the hydraulic rod 642.

[0073] Please see Figure 1 , Figure 9 , Figure 10 , Figure 11 and Figure 12 The second limiting mechanism 8 also includes:

[0074] The frame 82 is fixedly disposed on both sides of the recessed portion of the limiting seat 81, so that a cavity 86 is formed between the frame 82 and the recessed portion of the limiting seat 81, and the auxiliary mechanism 85 is located within the cavity 86. The auxiliary mechanism 85 includes:

[0075] Mounting base 852 is fixedly disposed inside the limiting base 81 and located in the cavity 86. Pressure sensor 854 is fixedly disposed on the side of mounting base 852 near the limiting arm 61. Housing 851 extending to the outside of the limiting base 81 is sleeved on the side wall of mounting base 852 and sleeved on the outside of pressure sensor 854. Abutment plate 856 is fixedly disposed on the side of housing 851 near the limiting arm 61.

[0076] The limiting ring 853 is fixedly disposed on the inner side of the limiting seat 81, and the inner wall of the limiting ring 853 is sleeved on the outer wall of the housing 851. The inner wall diameter of the limiting ring 853 is smaller than the side wall diameter of the abutment plate 856, so as to limit the movement of the housing 851.

[0077] Auxiliary mechanism 85 also includes:

[0078] The first movable through groove 857 is opened on the side wall of the mounting base 852 and arranged in a circular array with the center point of the mounting base 852. The first movable through groove 857 extends to the outside of the limiting seat 81.

[0079] The second movable channel 855 is opened on the side wall of the housing 851 and arranged in a circular array with the center point of the housing 851. The second movable channel 855 and the first movable channel 857 are arranged alternately so that the side wall of the housing 851 is fitted into the first movable channel 857, thereby allowing the housing 851 to move along the first movable channel 857.

[0080] In specific implementation, after the limiting arm 61 is embedded in the recess of the limiting seat 81, the telescopic rod of the hydraulic rod 642 points towards the frame 82. Then, the hydraulic rod 642 is activated, causing the telescopic shaft of the hydraulic rod 642 to extend and press against the abutment 856 and the housing 851, causing the housing 851 to press against the pressure sensor 854. When the pressure sensor 854 reaches the specified pressure information, the extension of the hydraulic rod 642 is stopped, thereby limiting the limiting seat 81 and preventing the limiting seat 81 from moving laterally on the side wall of the limiting arm 61, thereby preventing the basket 7 from moving laterally and improving the stability of the basket 7.

[0081] The pressure sensor 854 facilitates the monitoring of the degree of compression of the housing 851 by the hydraulic rod 642, so as to avoid the hydraulic rod 642 from limiting the limit seat 81 from both sides of the limit arm 61 when the position of the limit arm 61 entering the limit seat 81 is not in the center, that is, when the blank space on both sides of the limit arm 61 is not the same, thus preventing the limit seat 81 from moving laterally.

[0082] By setting a limit ring 853 to limit the movement of the housing 851, the hydraulic rod 642 is prevented from exerting excessive pressure on the housing 851 and pressure sensor 854 during violent shaking, thus avoiding damage to the pressure sensor 854 and facilitating its long-term use.

[0083] The first movable through groove 857 and the second movable through groove 855 facilitate stable movement of the housing 851 along the first movable through groove 857, which is convenient for practical use.

[0084] Please see Figure 4 The connecting component 9 includes:

[0085] The connecting arm 92 is fixedly mounted on the top of the basket 7 with the center point of the basket 7. The top of the connecting arm 92 is fixedly mounted on the base plate 91. The sides of the limiting seats 81 that are close to each other are fixedly connected to the two sides of the base plate 91 respectively.

[0086] In practical implementation, the connecting arm 92 and the base plate 91 facilitate the rigid connection of the basket 7, thereby improving the stability of the basket 7 after the limiting arm 61 clamps and fixes the limiting seat 81.

[0087] Please see Figure 13 and Figure 14 The drive mechanism 11 includes:

[0088] A support base 114 is fixedly disposed at the bottom of the second connecting base 5 and symmetrically arranged with respect to the center point of the second connecting base 5. A rotating base 116 is fixedly disposed on the outer side of the support base 114. The outer side of the rotating base 116 is rotatably connected to the top of the limiting arm 61. A rotating rod 115 is rotatably disposed on the outer side of the rotating base 116, and the side wall of the rotating rod 115 is fixedly connected to the top of the limiting arm 61. The two rotating rods 115 are connected by a first transmission mechanism 113 so that the two rotating rods 115 rotate synchronously and in opposite directions, thereby causing the limiting arms 61 on both sides of the second connecting base 5 to rotate closer to or further away from each other along the rotating rod 115.

[0089] The servo motor 111 is fixedly mounted on the top of the second connecting seat 5. The output shaft of the servo motor 111 is connected to one of the rotating rods 115 through the second transmission mechanism 112.

[0090] The first transmission mechanism 113 includes a first rotating shaft rotatably mounted on the side wall of the support base 114. Two first gears are fixedly sleeved on the side wall of the first rotating shaft. A second gear is fixedly sleeved on the side wall of one rotating rod 115, and a third gear is fixedly sleeved on the side wall of the other second rotating rod 115. One of the first gears meshes with the second gear, and the other first gear is connected to the third gear via a chain. Thus, through the meshing of one of the first gears and the second gear, the rotating rod 115 with the second gear rotates in the opposite direction to the second rotating shaft. Furthermore, by connecting the second rotating shaft to the rotating rod 115 with the third gear, the two rotating rods 115 rotate synchronously in opposite directions, so that the bottom of the limiting arm 61 can rotate closer to or further away from each other.

[0091] The second transmission mechanism 112 includes a fourth gear, which is fixedly sleeved on the side wall of the rotating rod 115 on which the second gear is mounted. The output shaft of the servo motor 111 is fixedly mounted on a second rotating shaft via a coupling, and the second rotating shaft is rotatably connected to the second connecting seat 5. A fifth gear is fixedly sleeved on the side wall of the second rotating shaft. The fifth gear and the fourth gear are connected by a chain drive, thereby driving the rotating rod 115 to rotate.

[0092] In specific implementation, the servo motor 111 is started. The output shaft of the servo motor 111 drives the rotating rod 115 with the second gear installed to rotate through the second transmission mechanism 112. The rotating rod 115 drives another rotating rod 115 to rotate synchronously in the opposite direction through the first transmission mechanism 113, so that the limiting arms 61 move closer or further away from each other along the rotating rod 115 to clamp and fix the limiting seat 81.

[0093] The first transmission mechanism 113 is designed to make the two rotating rods 115 rotate synchronously and in opposite directions. The second transmission mechanism 112 is designed to make the servo motor 111 drive the rotating rods 115 to rotate at the top of the second connecting seat 5. The first transmission mechanism 113 and the second transmission mechanism 112 are common mechanical linkages and are existing technologies, so they will not be described in detail here.

[0094] The limiting arm 61 is rotatably connected to the rotating seat 116, and the rotating rod 115 is fixedly connected to the limiting arm 61. The limiting arm 61 is rotated by the rotating rod 115, so that the weight borne by the limiting arm 61 is not entirely borne by the rotating rod 115, but is shared by the rotating seat 116 and the rotating rod 115, thereby improving the stability of the limiting arm 61.

[0095] The outer sides of both the first transmission mechanism 113 and the second transmission mechanism 112 are provided with protective covers to prevent the first transmission mechanism 113 and the second transmission mechanism 112 from being hit by collisions, etc., and to play a protective role.

[0096] Example 2: Please refer to Figure 1 and Figure 3 The difference between this embodiment and Embodiment 1 lies in the following technical solution: a first hoisting mechanism 4 is provided at the bottom of the first connecting seat 2 to drive the second connecting seat 5 to rise and fall; and third limiting mechanisms 3 are provided on both sides of the first connecting seat 2 to limit the rise and fall of the second connecting seat 5. The third limiting mechanism 3 includes:

[0097] The first ear plate 33 is fixedly disposed on both sides of the first connecting seat 2;

[0098] The second ear plate 31 is fixedly disposed on both sides of the second connecting seat 5. The positioning rod 32 is located on both sides of the lifting arm through the first ear plate 33 and the second ear plate 31. The top of the second ear plate 31 is fixedly provided with a positioning rod 32 that penetrates the first ear plate 33. The top of the first ear plate 33 is provided with a positioning hole for the positioning rod 32.

[0099] The limiting block 34 is fixedly installed on the top of the positioning rod 32, and the side wall diameter of the limiting block 34 is larger than the inner wall diameter of the positioning hole, so as to prevent the positioning rod 32 from disengaging from the positioning hole.

[0100] In specific implementation, after the limiting arm 61 clamps and fixes the limiting seat 81, the basket 7 is limited. In order to facilitate the hoisting of the power grid infrastructure in the basket 7 to the designated position, the second connecting seat 5 is driven to descend by the first hoisting mechanism 4, so as to facilitate the placement of the second connecting seat 5 and the basket 7 to the designated position. When the second connecting seat 5 descends, it drives the second ear plate 31 and the positioning rod 32 to move, so that the positioning rod 32 moves the positioning hole at the top of the first ear plate 33, thereby limiting the descent of the second connecting seat 5 and the basket 7, avoiding the second connecting seat 5 being connected only by the cable of the first hoisting mechanism 4, and improving the stability of the movement of the basket 7.

[0101] With the cooperation of the first limiting mechanism 6 and the second limiting mechanism 8, the basket 7 can be raised to the highest position and clamped and fixed to the limiting seat 81 when it shakes violently, thereby limiting the basket 7 and reducing the degree of shaking. After the basket 7 is limited by the first hoisting mechanism 4 and the third limiting mechanism 3, the basket 7 can be controlled to move down a certain height. During the movement, the stability of the basket 7 is improved by the cooperation of the positioning rod 32 and the positioning hole, so that the basket 7 can be placed in the designated position for power grid infrastructure construction.

[0102] By setting the first ear plate 33 and the second ear plate 31, it is easy to position the positioning rod 32 on both sides of the lifting arm, so as to avoid the movement of the positioning rod 32 affecting the normal use of the lifting arm, and to facilitate the installation of the positioning rod 32 of a specified length, so as to set the length of the positioning rod 32 according to the actual situation, so as to move the basket 7 down a specified distance stably through the first hoisting mechanism 4.

[0103] The positioning rod 32 is limited by the limiting block 34 to prevent it from disengaging from the positioning hole, thereby self-locking the hoisting of the first hoisting mechanism 4 and preventing it from falling.

[0104] The first hoisting mechanism 4 includes:

[0105] The first winch is fixedly installed at the bottom of the first connecting seat 2. The bottom of the cable of the first winch is fixedly provided with a first hook. The first hook is connected to the lifting lug at the top of the second connecting seat 5 to lift the second connecting seat 5.

[0106] In practice, the first hook at the bottom of the cable is connected to the lifting lug at the top of the second connecting seat 5, so that the second connecting seat 5 can be lifted by the first winch.

[0107] The bottom of the second connecting seat 5 is provided with a second hoisting mechanism 10 for raising and lowering the basket 7. The second hoisting mechanism 10 includes:

[0108] The second winch is fixedly installed at the bottom of the second connecting seat 5. The bottom of the cable of the second winch is fixedly provided with a second hook. The second hook is connected to the lifting lug at the top of the base plate 91 to lift the basket 7.

[0109] In practice, the second hook at the bottom of the cable is connected to the lifting lug at the top of the base plate 91 so that the base plate 91 and the basket 7 can be lifted by the first winch.

[0110] The first winch and pressure sensor 854 of this invention are connected to the controller and external power supply via wires for actual control and use. The hydraulic structure of this invention, such as the hydraulic rod 642, is connected to an external hydraulic system via oil circuits for actual control and use. The above are all prior art and will not be described in detail here.

[0111] This invention also provides a method for using a hoisting device for power grid infrastructure construction. The method includes the following steps:

[0112] S1: Place the power grid infrastructure to be hoisted into the hoisting basket 7, and then lift the hoisting basket 7 through the second hoisting mechanism 10 to move the power grid infrastructure to the designated location;

[0113] S2: During the hoisting process, if the basket 7 shakes significantly due to the influence of sea wind, the basket 7 is hoisted to the highest position, that is, the position where the second winch winds the cable to the maximum extent. Then, the basket 7 is clamped and fixed by the cooperation of the first limiting mechanism 6 and the second limiting mechanism 8. Furthermore, the basket 7 is further fixed by the cooperation of the buckle mechanism 64 and auxiliary components to limit the violent shaking of the basket 7.

[0114] To ensure stable hoisting under sea wind conditions, the first hoisting mechanism 4 and the third limiting mechanism 3 work together to allow the basket 7 to descend stably a certain distance, thereby facilitating the hoisting of power grid infrastructure and the construction of offshore platform-based observation stations.
