[0038] As Figure 1 And Figure 2 Shown, according to an embodiment of the present disclosure, a lifting operation platform device 100 for a vortex well is provided, including: a platform body 110, which is movably arranged in the vortex well 100'; a plurality of hoisting assemblies 120, each hoisting assembly 120 includes a driving part 121, a guide pulley 122 and a traction rope 123, the guide pulley 122 is arranged at the edge of the wellhead 101' of the vortex well 100', one end of the traction rope 123 is connected to the driving part 121, and the other end bypasses the guide pulley 122 and is connected to the platform body 110, the driving part 121 is used to release or wind up the traction rope 123 so that the platform body 110 moves along the depth direction of the vortex well 100'; wherein, the guide pulleys 122 of the plurality of hoisting assemblies 120 are arranged at intervals along the edge of the wellhead 101' of the vortex well 100'.

[0039] The lifting operation platform device 100 for a vortex well provided by an embodiment of the present disclosure includes the aforementioned platform body 110 and a plurality of the aforementioned hoisting components 120. In practical applications, the aforementioned lifting operation platform device 100 for a vortex well can be applied to operations such as engineering construction, maintenance, repair, and anti-corrosion treatment of the inner wall of the vortex well 100', or used as a device of the vortex well 100'. Based on the aforementioned settings, the lifting operation platform device 100 for a vortex well can use the platform body 110 to carry operators and operation supplies, so as to facilitate the operators to perform operations in the vortex well 100'; the driving parts 121 of the plurality of the aforementioned hoisting components 120 can drive the platform body 110 by releasing or winding up the aforementioned towing rope 123, so that the platform body 110 moves along the depth direction of the vortex well 100', facilitating the operators to perform operations at different depth positions in the well, and the plurality of hoisting components 120 can cooperate with each other to jointly hoist and drive the platform body 110, which is beneficial to reducing the risk of the platform body falling off. On the one hand, the aforementioned guide pulley 122 can guide the movement direction of the towing rope 123 and can change the force-bearing direction of the towing rope 123, which is beneficial to improving the movement stability and force-bearing condition of the towing rope 123, reducing the wear of the towing rope 123, extending the service life of the towing rope 123, and improving the safety of the towing rope 123; on the other hand, by arranging the guide pulley 122 at the edge of the wellhead 101' of the vortex well 100', the towing rope 123 can extend into the well in a form relatively close to the side wall of the vortex well 100', so that the towing rope 123 can avoid the middle areas of the wellhead 101' and the inner space of the well, leaving more space for other lifting tools to enter and exit the vortex well 100 during the operation, reducing the risk of interference and collision between the hoisting component 120 and the aforementioned other lifting tools, which is beneficial to improving the safety and operation efficiency of the corresponding operation and reducing the implementation cost of the corresponding operation; on the other hand, by arranging the guide pulleys 122 of the plurality of hoisting components 120 at intervals along the edge of the wellhead 101' of the vortex well 100', the towing ropes 123 of the plurality of hoisting components 120 can extend into the well from different directions, and it is convenient for the plurality of towing ropes 123 to be connected to different positions of the platform body 110, so as to ensure the stability and safety of the platform body 110 and reduce the risk of the platform body 110 tilting or falling off.

[0040] It can be understood that the aforementioned other lifting tools can be, but are not limited to, the lifting tools of lifting equipment for lifting operation supplies. The aforementioned lifting equipment can be, but is not limited to, truck cranes, gantry cranes, etc. The aforementioned operation supplies can be, but are not limited to, materials, tools, spare parts, etc. required for construction operations on the vortex well 100'.

[0041] It can be understood that, such as Figure 1 and Figure 2As shown, in practical applications, the aforementioned driving part 121 can be arranged at the top of the swirl well 100' and away from the wellhead 101' of the swirl well 100' to further reduce the space occupied by the hoisting assembly 120 near the wellhead 101' and reduce the risk of interference between the hoisting assembly 120 and the aforementioned other lifting tools. The aforementioned driving part 121 can include a motor and a drum, and the aforementioned motor is used to drive the aforementioned drum to rotate, and one end of the aforementioned traction rope 123 is connected to the aforementioned drum.

[0042] It can be understood that each of the aforementioned hoisting assemblies 120 can include a plurality of the aforementioned guide wheels 122. Correspondingly, in the case where each of the aforementioned hoisting assemblies 120 includes a plurality of the aforementioned guide wheels 122, at least one guide wheel 122 of each hoisting assembly 120 is arranged at the edge of the aforementioned wellhead 101', and the remaining guide wheels 122 are arranged between the guide wheels 122 at the edge of the wellhead 101' and the driving part 121. In the case where each of the aforementioned hoisting assemblies 120 includes a plurality of the aforementioned guide wheels 122, the winding directions of the traction rope 123 on each guide wheel 122 are different, which is beneficial to further improving the stress condition of the traction rope 123. Exemplarily, the number of guide wheels 122 of each of the aforementioned hoisting assemblies 120 can be greater than or equal to 2, for example, it can be 3, 4, 5, etc.

[0043] It can be understood that the cross-sectional shape of the platform body 110 can be determined according to the cross-sectional shape of the swirl well 100', and the cross-sectional area of the platform body 110 is smaller than the cross-sectional area of the swirl well 100', so as to facilitate the smooth lifting and lowering of the platform body 110 in the swirl well 100' and reduce the risk of interference between the platform body 110 and the inner side wall of the swirl well 100'. It can be understood that the cross-section of the aforementioned platform body 110 refers to the section of the platform body 110 perpendicular to its height direction, and the cross-section of the aforementioned swirl well 100' refers to the section of the swirl well 100' perpendicular to its depth direction; Exemplarily, the cross-sectional shape of the platform body 110 can be similar to the cross-sectional shape of the swirl well 100'. For example, when the cross-section of the swirl well 100' is circular, the cross-sectional shape of the platform body 110 can be a circle with a diameter smaller than the cross-sectional diameter of the swirl well 100'.

[0044] It can be understood that in practical applications, the load-bearing performance of the aforementioned hoisting assembly 120 can be set according to actual needs, and no excessive limitation is made here. Exemplarily, the load-bearing performance parameters of each hoisting assembly 120 can be calculated according to the weight of the platform body 110 and the maximum load of the platform body 110, and then the driving part 121, guide wheels 122 and traction rope 123 with matching load-bearing performance can be selected.

[0045] In some feasible examples, the aforementioned driving part 121 can be an electric hoist of YZ1 type. The lifting weight of the electric hoist of YZ1 type is 2T, the rated voltage is 380V, the lifting height is 1 / 100m, and the working system can be 25% JC.

[0046] In some feasible examples, the platform body 110 is substantially cylindrical, and the ratio of the diameter of the platform body 110 to the diameter of the swirl well 100' is greater than or equal to 95% and less than 1. Based on this, the movement space of the platform body 110 in the radial direction of the swirl well 100' can be reduced, and the probability of the platform body 110 shaking significantly can be reduced, which is beneficial to further improving the stability and safety of the platform body 110; Exemplarily, when the diameter of the swirl well 100' is 4.5m, the diameter of the aforementioned platform body 110 can be, but is not limited to, 4.3m. Correspondingly, the sum of the square of the height of the platform body 110 and the square of the diameter of the platform body 110 can be set to be greater than the square of the diameter of the swirl well 100', so as to avoid the risk of the platform body 110 tilting or flipping significantly in the swirl well 100'; Exemplarily, when the diameter of the swirl well 100' is 4.5m and the diameter of the aforementioned platform body 110 is 4.3m, the height of the aforementioned platform body 110 can be, but is not limited to, 1.4m.

On the one hand, this can facilitate the multi-point connection of the towing rope 123 to the bearing part 111 to improve the stability of the bearing part 111. On the other hand, it can also make the towing rope 123 in the well extend between the inner side wall of the swirl well 100' and the connecting part 112, so that the towing rope 123 in the well is in the edge area of the well, further avoiding the central drive in the well, facilitating the passage of other lifting tools, and reducing the risk of interference between the towing rope 123 in the well and other lifting tools.

[0060] In this technical solution, the aforementioned bearing plate may be made of checkered plate; based on the aforementioned settings, on the one hand, the bearing performance of the bearing plate can be improved, thereby enhancing the safety and structural stability of the platform body 110; on the other hand, the anti-slip performance of the bearing wall can be enhanced, reducing the risk of slipping of operators and operating supplies on the bearing wall.

[0066] It can be understood that the aforementioned preset speed can be set according to actual needs and will not be limited here.
