Description

Technical Field

[0001] The utility model relates to the technical field of bridge foundation engineering, in particular to a positioning device. Background Art

[0002] As my country's transportation infrastructure continues to advance, bridge construction, as crucial nodes along major transportation routes, has become increasingly important. Due to the complex and highly variable natural environments of river and sea bridges, the design and construction of underwater pile foundations is more challenging and requires more consideration than onshore pile foundation construction. Steel casing installation, the initial step in pile foundation construction, directly impacts the smooth progress of subsequent pile foundation work.

[0003] For example, a Chinese utility model patent (CN217556921U) discloses a positioning device for steel casings of deep-water bridge pile foundations, which states: "It can conveniently play a positioning and guiding role for the steel casing when placing it, so that it can ensure the vertical placement of the steel casing with high reliability." It also states: "In the prior art, when lifting and positioning the steel casing, it is usually positioned and placed by the steel casing's own weight, and there is no guiding mechanism for it, and it cannot ensure that it maintains a vertical positioning." Technical problems.

[0004] To sum up, it can be seen that the prior art utilizes three arc plates to simultaneously move toward the middle of the device under the drive of a motor, which plays a positioning and guiding role for the steel casing when placing it, so that it can ensure the vertical placement of the steel casing. However, this method has the following technical problems: However, in the actual use of the above-mentioned device, since the steel casing needs to be positioned and guided, the center axis of the device needs to be aligned with the center axis of the steel casing installation. In the actual installation of the positioning device, the center axis of the device may deviate from the center axis of the position where the steel casing is to be installed due to installation errors, which in turn requires the positioning device to be removed and reinstalled. This process is more troublesome and prolongs the construction period. For this reason, the present application proposes a positioning device to provide a new technical solution to solve the technical problems mentioned in the above-mentioned patent. Utility Model Content

[0005] Based on this, it is necessary to provide a positioning device to address the above technical problems. The device shell is fixed in a suitable position by a fixing cone, and then the deviation between the center axis of the device shell and the center axis of the steel casing to be installed is measured. When there is a deviation, the front, rear, left and right sliding tooth plates can be adjusted respectively according to the position of the center axis of the steel casing and the radius size of the steel casing. The push-pull plate is pushed so that the sliding tooth plate drives the corresponding string arc plate or king-shaped arc plate to move toward the center of the device shell until some of the ball bearings on the string arc plate or king-shaped arc plate are close to the area where the steel casing is to be installed. During this process, the limiting claw restricts the corresponding sliding tooth plate, avoiding the sliding tooth plate from sliding away from the center of the device shell, thereby ensuring the stability of the device. At the same time, it reduces the need to remove and reinstall the installed device due to the offset between the center axis of the device and the center axis of the steel casing installation, thereby improving the fault tolerance of the device installation and thus improving the practicality of the device.

[0028] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0029] As described in the background technology, however, in the actual use of the above-mentioned device, since the steel casing needs to be positioned and guided, the center axis of the device needs to be aligned with the center axis of the steel casing installation. However, during the actual installation of the positioning device, the center axis of the device may deviate from the center axis of the position where the steel casing is to be installed due to installation errors, which in turn requires the positioning device to be removed and reinstalled. This process is more troublesome and prolongs the construction period.

[0030] In order to solve this technical problem, the utility model provides a positioning device, which is used for the installation and positioning of steel casings of deep-water bridges.

[0031] Specifically, please refer to Figure 1-Figure 2 , the positioning device specifically includes:

[0032] The device housing 1 has a plurality of fixed cones 2 fixedly connected to the bottom of the device housing 1, guide mechanisms 3 are respectively provided on the front, back, left and right sides of the device housing 1, two auxiliary mechanisms 4 are provided on the device housing 1, and a plurality of reinforcing plates 5 are fixedly connected to the inner wall of the device housing 1;

[0033] The guide mechanism 3 includes a sliding tooth plate 6, a push-pull plate 7, a scale 8, a limiting assembly, and a guide assembly. The inner wall of the device housing 1 is slidingly connected to the sliding tooth plate 6, the inner wall of the sliding tooth plate 6 is fixedly connected to the scale 8, and the outer wall of the sliding tooth plate 6 is fixedly connected to the push-pull plate 7.

[0034] The positioning device provided by the present invention fixes the device shell 1 in a suitable position by fixing the cone 2, and then measures the deviation between the center axis of the device shell 1 and the center axis of the steel casing to be installed. When there is a deviation, the front, rear, left and right sliding tooth plates 6 can be adjusted respectively according to the position of the center axis of the steel casing and the radius size of the steel casing, and the push-pull plate 7 is pushed so that the sliding tooth plate 6 drives the corresponding string arc plate 13 or king-shaped arc plate 14 to move toward the center of the device shell 1 until some of the balls 15 on the string arc plate 13 or king-shaped arc plate 14 are close to the area where the steel casing is to be installed. During this process, the limiting claw 10 limits the corresponding sliding tooth plate 6, avoiding the sliding tooth plate 6 from sliding in the direction away from the center of the device shell 1, thereby ensuring the stability of the device. At the same time, it reduces the situation where the installed device needs to be dismantled and reinstalled due to the deviation between the center axis of the device and the center axis of the steel casing installation, thereby improving the fault tolerance of the device installation and thus improving the practicality of the device.

[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figure 2-Figure 3 , a positioning device comprising:

[0038] The limiting assembly includes a rotating rod 9, the inner wall of the device housing 1 is rotatably connected to the rotating rod 9, the outer wall of the rotating rod 9 is fixedly connected to a limiting claw 10 adapted to the sliding tooth plate 6, the outer wall of the rotating rod 9 and the upper and lower sides of the limiting claw 10 are respectively fixedly connected to a fixing ring 11, the outside of the rotating rod 9 and the upper and lower sides of the limiting claw 10 are respectively sleeved with a first torsion spring 12, the two ends of the first torsion spring 12 are respectively fixedly connected to the outer wall of the fixing ring 11 and the inner wall of the device housing 1, the elastic force of the first torsion spring 12 makes the limiting claw 10 tend to be tightly attached to the outside of the sliding tooth plate 6.

[0039] The guide assembly includes a string arc plate 13 and a king-shaped arc plate 14. The front and rear two sliding tooth plates 6 are fixedly connected to the string arc plate 13 at one end close to the central axis of the device housing 1, and the left and right two sliding tooth plates 6 are fixedly connected to the king-shaped arc plate 14 at one end close to the central axis of the device housing 1. The string arc plate 13 is adapted to the king-shaped arc plate 14, and the inner walls of the string arc plate 13 and the king-shaped arc plate 14 are respectively connected with a plurality of balls 15 in a rolling manner. The balls 15 can make the steel casing move more smoothly relative to the string arc plate 13 and the king-shaped arc plate 14, and the string arc plate 13 and the king-shaped arc plate 14 can cross each other to adapt to the situation where the size of the steel casing is relatively small, or there is a deviation between the central axis of the position where the steel casing is to be installed and the central axis of the installed device.

[0040] Through the above structural design, the device housing 1 is fixedly installed in a suitable position by the fixing cone 2, and then the deviation between the center axis of the device housing 1 and the center axis of the steel casing to be installed is measured. When there is a deviation, the front, rear, left and right sliding tooth plates 6 can be adjusted respectively according to the position of the center axis of the steel casing to be installed and the radius size of the steel casing, and the push-pull plate 7 is pushed so that the sliding tooth plate 6 drives the corresponding string arc plate 13 or king-shaped arc plate 14 to move toward the center of the device housing 1 until some of the balls 15 on the string arc plate 13 or king-shaped arc plate 14 are close to the area where the steel casing is to be installed. During this process, the limiting claw 10 rotates on the rotating rod 9 as the sliding tooth plate 6 moves, and always maintains a tendency to be close to the outer wall of the sliding tooth plate 6 under the action of the elastic force of the first torsion spring 12. After the two string-shaped arc plates 13 and the two king-shaped arc plates 14 are moved to the appropriate positions respectively, the steel casing can be lowered so that the steel casing is in the space formed by the two string-shaped arc plates 13 and the two king-shaped arc plates 14, and then the two string-shaped arc plates 13 and the king-shaped arc plates 14 are restricted and vertically inserted into the predetermined position. When it is necessary to slide the sliding tooth plate 6 in the direction away from the center of the device housing 1, the rotating rod 9 can be rotated first to control the limiting claw 10 to leave the sliding tooth plate 6. During this process, the first torsion spring 12 is deformed, and then the sliding tooth plate 6 is pulled in the direction away from the center of the device housing 1. After reaching the appropriate position, the rotating rod 9 is released, and the rotating rod 9 is driven to rotate under the action of the elastic force of the first torsion spring 12, so that the limiting claw 10 is close to the outer wall of the sliding tooth plate 6.

[0041] Example 2:

[0042] The positioning device provided in Example 1 is further optimized, specifically, as Figure 4-Figure 6 As shown, the auxiliary mechanism 4 includes a support shell 16, a rotating shaft 17, a reset assembly, and a connecting assembly. The top of the device housing 1 is fixedly connected to the support shell 16, the upper surface of the inner wall of the support shell 16 is rotatably connected to the rotating shaft 17, and the bottom end of the rotating shaft 17 is rotatably connected to the top of the device housing 1.

[0043] The reset assembly includes a partition plate 18, the outer wall of the rotating shaft 17 is fixedly connected to the partition plate 18, the outer side of the rotating shaft 17 is provided with a second torsion spring 19, and the two ends of the second torsion spring 19 are respectively fixedly connected to the upper surface of the inner wall of the support shell 16 and the top of the partition plate 18. The partition plate 18 provides support for the second torsion spring 19 and separates the second torsion spring 19 from the auxiliary rope 20 to prevent the auxiliary rope 20 from being wrapped around the rotating shaft 17 and offset, which affects the second torsion spring 19.

[0044] The connecting assembly includes an auxiliary rope 20, the outer wall of the rotating shaft 17 is fixedly connected with the auxiliary rope 20, the end of the auxiliary rope 20 away from the rotating shaft 17 passes through the support shell 16 and is fixedly connected with a connecting ring 21, the top of the device housing 1 is fixedly connected with a fixed column 22, and the connecting ring 21 is sleeved on the outside of the fixed column 22. The auxiliary ropes 20 in the two auxiliary mechanisms 4 are arranged to cross vertically, and the point where the two auxiliary ropes 20 cross falls on the central axis of the device housing 1.

[0045] Through the above-mentioned structural design, by pulling the connecting ring 21, the corresponding auxiliary rope 20 is driven to leave the support shell 16, so that the rotating shaft 17 rotates accordingly, and the second torsion spring 19 is deformed accordingly. The connecting ring 21 is hung on the fixed column 22 and pressed to the bottom, and then the auxiliary rope 20 is kept horizontal. Another connecting ring 21 is hung on the corresponding fixed column 22, which can assist the operator to install the device housing 1 in the appropriate position. Then, before installing the steel casing, the connecting ring 21 is removed from the fixed column 22, and the auxiliary rope 20 can be moved toward the inside of the support shell 16 under the action of the elastic force of the corresponding second torsion spring 19.
