Description

Technical Field

[0001] This utility model relates to the field of drilling floating platform technology, and more specifically, it relates to an assembled drilling floating platform with support legs. Background Technology

[0002] In reservoir monitoring projects, a detection pile and corresponding detection equipment need to be installed within the reservoir. Drilling operations are typically performed using a drilling floating platform. However, existing drilling floating platforms, especially in smaller reservoirs, often require smaller platforms. These smaller platforms, with their smaller dimensions, reduce overall stability and the safety and efficiency of the drilling operation. Furthermore, the pontoons of existing platforms are usually fixed to the lower part of the platform and cannot be disassembled, resulting in a large footprint and making transportation and site use inconvenient. Additionally, damaged pontoons cannot be replaced individually, increasing maintenance costs. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an assembled drilling floating platform with supporting legs, which has the following advantages:

[0016] 1. By using a combination of platform plate, impact reverse circulation drilling rig, hydraulic cylinder, steel sleeve, support legs, support plate, fixing nail, fixing shell, double screw, moving seat, clamping plate, insertion rod and insertion hole, the entire small drilling floating platform can be fixed to the riverbed of the reservoir, which increases the stability of the entire device and ensures the safety and efficiency of drilling operations. At the same time, the support legs are easy to disassemble and can be removed during transportation, thus facilitating transportation. When the support legs are damaged, they can also be disassembled and replaced individually.

[0017] 2. By using the mounting slot, mounting base, float box, fixed chamber, lead screw, moving plate, driven bevel gear, fixed rod, throttle and drive bevel gear in combination, the float box can be disassembled during transportation, thereby reducing the area occupied and facilitating transportation.

[0028] Please see Figures 1-5 A modular drilling floating platform with supporting legs includes a platform plate 1. An impact reverse circulation drill rig 2 is mounted on the platform plate 1. Four hydraulic cylinders 3 and four steel sleeves 4 are fixedly mounted on the platform plate 1. A supporting leg 5 is movably mounted inside each steel sleeve 4. A supporting plate 6 is fixedly connected to the lower end of the supporting leg 5 through the steel sleeve 4. A fixing nail 7 is fixedly mounted at the lower end of the supporting plate 6. A fixed shell 8 is fixedly mounted at the driving end of each hydraulic cylinder 3. A bidirectional screw 9 is rotatably mounted inside the fixed shell 8. One end of the bidirectional screw 9 extends to the outside of the fixed shell 8. Two movable seats 10 are threadedly connected to the bidirectional screw 9. A U-shaped clamping plate 11 is fixedly mounted at one end of each movable seat 10 through the fixed shell 8. An insertion rod 12 is fixedly mounted on the clamping plate 11. An insertion hole 13 that mates with the insertion rod 12 is provided on the supporting leg 5.

[0029] In this embodiment, the upper end of the support leg 5 passes through the inside of the steel sleeve 4, the insertion hole 13 is aligned with the two insertion rods 12, and the bidirectional screw 9 is rotated. Since the bidirectional screw 9 has two threaded areas in opposite directions, the two moving seats 10 move in adjacent directions. The moving seats 10 drive the clamping plate 11 to move. With the cooperation of the two clamping plates 11, the support leg 5 is clamped. At the same time as the clamping plate 11 moves, the clamping plate 11 drives the insertion rod 12 to move, so that the insertion rod 12 is inserted into the insertion hole 13, thereby fixing the support leg 5. The entire drilling floating platform is placed in the reservoir at the drilling location. With the help of the pontoon 16, the platform plate 1 floats on the water surface. The four hydraulic cylinders 3 are activated, causing the fixed shell 8, clamping plate 11, insertion rod 12, and fixed support leg 5 to move downwards. The support leg 5 moves the support plate 6 downwards, and the support plate 6 moves to the riverbed. The support plate 6 then moves the fixing nail 7 downwards, inserting it into the riverbed, thus fixing the entire drilling floating platform. Simultaneously, this method can be used to adjust the length of the support leg 5's movement, thereby adjusting the balance of the platform plate 1. The impact reverse circulation drilling rig 2 is then started for drilling operations. Since the impact reverse circulation drilling rig 2 is a mature product in existing technology, its specific structure and working principle will not be described in detail here.

[0030] Please see Figures 1-5As one embodiment of the installation of the pontoon 16: the lower end of the platform plate 1 is provided with two T-shaped mounting slots 14, each mounting slot 14 is movably provided with a mounting seat 15, the lower end of the mounting seat 15 is fixedly provided with the pontoon 16, the platform plate 1 is provided with two fixed chambers 17, each fixed chamber 17 is rotatably provided with a lead screw 18, the lead screw 18 is threadedly connected with a moving plate 19, the lead screw 18 is fixedly provided with a driven bevel gear 20, the moving plate 19 is fixedly provided with a plurality of fixed rods 21 on one side, one end of each fixed rod 21 is inserted into the mounting seat 15, the platform plate 1 is rotatably provided with two throttle handles 22, one end of each throttle handle 22 extends into the fixed chamber 17 and is fixedly provided with a driving bevel gear 23.

[0031] Specifically, the float 16 is moved so that the mounting base 15 is inserted into the mounting slot 14. The handle 22 is rotated, causing the drive bevel gear 23 to rotate. Since the drive bevel gear 23 meshes with the driven bevel gear 20, the driven bevel gear 20 rotates. The driven bevel gear 20 then rotates the lead screw 18. Since the lead screw 18 is threadedly connected to the moving plate 19, the moving plate 19 moves along the fixed chamber 17. The moving plate 19 moves the fixing rod 21, causing it to insert into the mounting base 15 and thus fix the mounting base 15 in place, thereby installing the float 16. The float 16 can be disassembled and replaced or transported using the reverse operation.

[0032] Please see Figures 1-5 As one embodiment of the bidirectional screw 9: a toothed ring 24 is fixedly provided at one end of the bidirectional screw 9, a limiting shell 25 is movably provided on the outside of the toothed ring 24, two pushing chambers 26 are provided inside the fixed shell 8, a pushing plate 27 is movably provided in each pushing chamber 26, a spring 28 is provided between the pushing plate 27 and the pushing chamber 26, and two moving rods 29 are fixedly provided on one side of the limiting shell 25, one end of the moving rod 29 extends into the pushing chamber 26 and is fixedly connected to the pushing plate 27.

[0033] Specifically, when the bidirectional screw 9 needs to rotate, the limiting shell 25 is pushed, causing the limiting shell 25 to separate from the gear ring 24. The limiting shell 25 drives the two moving rods 29 to move, and the moving rods 29 drive the push plate 27 to move. The spring 28 is compressed, and the bidirectional screw 9 can be rotated at this time. When the bidirectional screw 9 does not need to rotate, the limiting shell 25 is released. Under the push of the spring 28, the push plate 27 drives the moving rods 29 to move back to their original positions. The moving rods 29 drive the limiting shell 25 to move, so that the limiting shell 25 moves to the outside of the gear ring 24, thereby limiting the gear ring 24.

[0034] In summary, when using the overall equipment:

[0035] When the float 16 needs to be installed, move the float 16 so that the mounting base 15 is inserted into the mounting slot 14. Turn the handle 22, which drives the drive bevel gear 23 to rotate. Since the drive bevel gear 23 meshes with the driven bevel gear 20, the driven bevel gear 20 rotates. The driven bevel gear 20 drives the lead screw 18 to rotate. Since the lead screw 18 is threadedly connected to the moving plate 19, the moving plate 19 moves along the fixed chamber 17. The moving plate 19 drives the fixed rod 21 to move, so that the fixed rod 21 is inserted into the mounting base 15, thereby fixing the mounting base 15 in place. The float 16 can then be installed. The reverse operation can be used to disassemble and replace the float 16 or to disassemble and transport it.

[0036] When the bidirectional screw 9 needs to be rotated, the limiting shell 25 is pushed, causing the limiting shell 25 to separate from the gear ring 24. The limiting shell 25 drives the two moving rods 29 to move, and the moving rods 29 drive the push plate 27 to move. The spring 28 is compressed, and the bidirectional screw 9 can be rotated at this time. When the bidirectional screw 9 does not need to be rotated, the limiting shell 25 is released. Under the push of the spring 28, the push plate 27 drives the moving rods 29 to move back to their original positions. The moving rods 29 drive the limiting shell 25 to move, so that the limiting shell 25 moves to the outside of the gear ring 24, thereby limiting the gear ring 24.

[0037] When the support leg 5 needs to be installed, pass the upper end of the support leg 5 through the inside of the steel sleeve 4, align the insertion hole 13 with the two insertion rods 12, and rotate the double-direction screw 9. Since the double-direction screw 9 has two threaded areas in opposite directions, the two moving seats 10 move in adjacent directions. The moving seats 10 drive the clamping plate 11 to move. With the cooperation of the two clamping plates 11, the support leg 5 is clamped. At the same time as the clamping plate 11 moves, the clamping plate 11 drives the insertion rod 12 to move, so that the insertion rod 12 is inserted into the insertion hole 13, thereby fixing the support leg 5. The entire drilling floating platform is placed in the reservoir at the drilling location. With the help of the pontoon 16, the platform plate 1 floats on the water surface. The four hydraulic cylinders 3 are activated, causing the fixed shell 8, clamping plate 11, insertion rod 12, and fixed support leg 5 to move downwards. The support leg 5 moves the support plate 6 downwards, and the support plate 6 moves to the riverbed. The support plate 6 then moves the fixing nail 7 downwards, inserting it into the riverbed, thus fixing the entire drilling floating platform. Simultaneously, this method can be used to adjust the length of the support leg 5's movement, thereby adjusting the balance of the platform plate 1. The impact reverse circulation drilling rig 2 is then started for drilling operations. Since the impact reverse circulation drilling rig 2 is a mature product in existing technology, its specific structure and working principle will not be described in detail here.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
