Description

Technical Field

[0001] This utility model patent relates to the field of reverse construction method for connecting steel pipe columns and tool columns, specifically, to a positioning platform based on tool column orifice positioning. Background Technology

[0002] When underground structures are constructed using the reverse construction method, the foundation piles typically employ a bottom-grown cast-in-place pile + structural column configuration, with steel pipe structural piles being a common form. As a permanent structure, steel pipe structural piles require stringent control over positioning and verticality. In reverse construction foundation engineering, the verticality deviation of the steel pipe structural column cannot exceed 1 / 300, and in some cases, it must reach 1 / 500. To ensure high precision, a full-casing full-rotation drilling rig is usually used for positioning. Since the full-casing full-rotation drilling rig extends approximately 3.5 meters above ground level, and the top elevation of the steel pipe column is generally below ground level, a tool column is used to connect the steel pipe structural column to the drilling rig borehole for auxiliary positioning. The tool column and steel pipe column are usually prefabricated in the factory and transported to the site for assembly after acceptance testing. Therefore, in addition to meeting the accuracy requirements for steel pipe structural column positioning, even higher requirements are placed on the docking accuracy between the steel pipe column and the tool column.

[0003] Currently available assisted positioning tools often rely on manual operation and have poor positioning accuracy. Utility Model Content

[0024] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0025] The positioning platform based on tool column orifice positioning includes four support legs 1 and a support platform 2 mounted on the support legs 1. The support platform 2 is characterized by a stable connection mechanism 10, an inlet 3, a base 4, a plurality of movable rods 5 slidably connected to the base 4, and a transmission wheel 6 above the base 4. The transmission wheel 6 has a plurality of arc-shaped grooves 7, and the movable rods 5 are slidably connected to the transmission wheel 6 through the arc-shaped grooves 7. Steel pipe columns 11 are arranged between the movable rods 5. A gear 8 is mounted on the support platform 2, a first servo motor 9 is connected to the gear 8, and the gear 8 is connected to the transmission wheel 6 in a transmission connection.

[0026] When it is necessary to align the center point of the steel pipe column 11 with the center point of the inlet 3, the steel pipe column 11 is first placed into the inlet 3. Then, the first servo motor 9 is started, which drives the gear 8 to rotate, thereby driving the transmission wheel 6 to rotate synchronously. Since several moving rods 5 are connected to the transmission wheel 6 through the arc groove 7, when the transmission wheel 6 moves, it drives several moving rods 5 to move towards the steel pipe column 11 synchronously, thereby pushing the steel pipe column 11 towards the center of the inlet 3, so that the center of the steel pipe column 11 coincides with the center of the inlet 3, thus achieving the purpose of precise positioning of the steel pipe column 11. This method is simple to operate, avoids the manual adjustment operation in the existing adjustment operation, further improves the adjustment efficiency and reduces the labor consumption.

[0027] Specifically, in this embodiment, the base 4 is provided with a plurality of connecting grooves 12, which are circumferentially distributed on the base 4 and adapted to a plurality of moving rods 5, so that the plurality of moving rods 5 can be slidably connected to the base 4 through the corresponding connecting grooves 12, so that when the moving rods 5 are driven by the transmission wheel 6, the moving rods 5 can only move along the direction of the connecting grooves 12, thereby restricting the direction of movement of the moving rods 5.

[0028] Specifically, in this embodiment, each of the several movable rods 5 is equipped with a connecting shaft 13 at one end that is far apart from each other. The size of the several connecting shafts 13 is adapted to the arc groove 7 and is slidably connected to the corresponding arc groove 7, so that the movable rod 5 can be slidably connected to the transmission wheel 6 through the compatibility between the connecting shaft 13 and the arc groove 7, thereby achieving the purpose of driving the movable rod 5 to move through the transmission wheel 6.

[0029] Specifically, in this embodiment, a limiting plate 14 is installed at one end of each of the several moving rods 5 that are close to each other. The several limiting plates 14 are circumferentially distributed inside the feed inlet 3, so that when the several moving rods 5 move, they will drive the several limiting plates 14 to move synchronously, thereby contacting the steel pipe column 11 through the limiting plates 14, thereby increasing the contact area between the steel pipe column 11 and the moving rods 5, and thus improving the connection stability between the moving rods 5 and the steel pipe column 11.

[0030] Specifically, in this embodiment, the support platform 2 is provided with a connecting platform 15. The connecting platform 15 is hollow inside, and the transmission wheel 6 is rotatably connected to the connecting platform 15, so that the transmission wheel 6 can be rotatably connected to the support platform 2 through the connecting platform 15, and the connecting platform 15 provides support for the transmission wheel 6, while ensuring the rotation state of the transmission wheel 6.

[0031] Specifically, in this embodiment, the support platform 2 is provided with a support platform 16 and a connecting plate 17. The gear 8 is located between the support platform 16 and the connecting plate 17. The first servo motor 9 is mounted on the connecting plate 17. The support platform 16 enables the gear 8 to be on the same plane as the transmission wheel 6, thereby achieving the transmission relationship between the gear 8 and the transmission wheel 6. The connecting plate 17 facilitates the connection between the output shaft of the first servo motor 9 and the gear 8, thereby driving the gear 8 to rotate.

[0032] Specifically, in this embodiment, the stable connection mechanism 10 includes two device plates 18 mounted on the support leg 1. Two drive shafts 19 are rotatably connected between the two device plates 18. Connecting rods 20 are installed at both ends of the two drive shafts 19. Extension legs 21 are provided on several connecting rods 20. Several extension legs 21 are slidably connected inside the corresponding support leg 1. A second servo motor 22 is installed at the bottom of one of the device plates 18. A worm gear 23 is connected to the output shaft of the second servo motor 22. Worm wheels 24 are driven to both sides of the worm gear 23. The two worm wheels 24 are respectively mounted on the two drive shafts 19.

[0033] Before the steel pipe column 11 is placed into the inlet 3, the user can drive the worm gear 23 to rotate via the second servo motor 22, thereby driving the worm wheel 24 to rotate, which in turn drives the two transmission shafts 19 to rotate. This, in turn, drives the corresponding extension leg 21 to move downward via the connecting rod 20, thereby inserting the extension leg 21 into the soil. This increases the connection depth between the positioning platform and the soil, thereby improving the stability of the positioning platform and preventing the positioning platform from shaking during the later positioning of the steel pipe column 11, which would affect the normal progress of the positioning work.

[0034] Specifically, in this embodiment, each of the supporting legs 1 has a receiving cavity 25 inside, and a number of extension legs 21 are adapted to the receiving cavity 25, so that the extension legs 21 can be slidably connected to the supporting leg 1 through the receiving cavity 25, thereby achieving the purpose of the extension legs 21 moving on the supporting leg 1.

[0035] Specifically, in this embodiment, a first movable groove 26 is provided on each of the several support legs 1. The first movable groove 26 is adapted to the connecting rod 20, so that the connecting rod 20 can be connected to the extension leg 21 through the first movable groove 26, and the connecting rod 20 can maintain a normal rotation state when it rotates through the setting of the first movable groove 26.

[0036] Specifically, in this embodiment, both device plates 18 are provided with second moving slots 27. The second moving slots 27 are adapted to the connecting rod 20, so that the connecting rod 20 can pass through the corresponding device plate 18 through the second moving slots 27, thereby avoiding contact and aggression between the connecting rod 20 and the device plate 18 when the connecting rod 20 rotates, thus ensuring the normal movement of the connecting rod 20.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
