Description

Technical Field

[0001] The utility model relates to the technical field of self-elevating platform seawater towers, in particular to a lifting limit guide device. Background Art

[0002] The seawater tower is a device used to supply water to the entire platform when the self-elevating platform is in lifting condition.

[0003] The Chinese utility model patent with publication number CN212506197U provides a guiding device suitable for a seawater tower. The device includes two pile driving pipes arranged on the pile legs of a self-elevating platform, and the seawater tower is located between the two pile driving pipes. It also includes an ear plate connected to the side of the seawater tower. There are two ear plates, which are respectively located between the seawater tower and the pile driving pipes; the ear plates are connected to rollers, which contact the surface of the corresponding pile driving pipes; the tops of the ear plates are connected to anti-falling structures; the anti-falling structure includes a baffle connected to the top of the ear plate, and a guide plate connected to the upper surface of the baffle.

[0004] During the use of this device, since the up and down movement of the seawater tower is achieved by relying on crane lifting, there is shaking during the up and down movement, which causes impact on the pile pipe. On the one hand, the shaft used to install the roller is easily deformed and damaged, making it impossible for the roller to fit tightly with the pile pipe, affecting the guiding accuracy, and even losing the rolling function in severe cases, directly causing serious wear on the outer wall of the pile pipe. On the other hand, since the installation position of the pile pipe support is perpendicular to the plane where the seawater tower and the pile pipe are located, and the impact force received by the pile pipe is mostly parallel to the plane where the seawater tower and the pile pipe are located, this makes the connection between the pile pipe support and the pile pipe, and between the pile pipe support and the pile leg easy to deform or even break, causing the pile pipe to shift and lose the guiding effect.

[0005] Therefore, the present invention proposes a lifting limit guide device to solve the above problems. Utility Model Content

[0026] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0027] Example

[0028] This embodiment provides a lifting and limiting guide device for guiding the lifting of a seawater tower 1 . A horizontal chord 3 is provided on one side of the seawater tower 1 . The lifting and limiting guide device includes a pile driving pipe 2 and a guide assembly 5 .

[0029] There are two pile pipes 2 symmetrically arranged on both sides of the seawater tower 1. The two pile pipes 2 are located on the same side of the horizontal chord 3 where the seawater tower 5 is located. The central axis of the pile pipe 2 is set vertically and perpendicular to the central axis of the horizontal chord 3. Each pile pipe 2 is connected to the horizontal chord 3 through a pile pipe support 4. The two ends of the pile pipe support 4 are respectively connected to the pile pipe 2 and the horizontal chord 3. The pile pipe support 4 is set at an angle and tilted from the connection with the pile pipe 2 in the direction away from the seawater tower 1, so that the seawater tower and the two pile pipes and the horizontal chord form an isosceles trapezoidal structure. This structure can make full use of the structural strength of the pile pipe support itself, and well disperse the impact force of the seawater tower on the pile pipe, thereby improving the structural strength of the pile pipe.

[0030] In this embodiment, the pile pipe support 4 includes a first curved plate 44, a first vertical plate 42, a first horizontal plate 43, and a second curved plate 41. The first curved plate 44 covers and is welded to the side of the horizontal chord 3 near the pile pipe 2. The second curved plate 41 covers and is welded to the outer wall of the pile pipe 2. The first horizontal plate 43 is horizontally arranged between the first curved plate 44 and the second curved plate 41. The ends of the first horizontal plate 43 are welded to the first curved plate 44 and the second curved plate 41, respectively. There are two first vertical plates 42, which are symmetrically arranged above and below the first horizontal plate 43. The first vertical plates 42 are vertically arranged in the radial direction of the pile pipe 2. The first vertical plate 42 is welded to the first horizontal plate 43, and the two sides of the first vertical plate 42 are welded to the first curved plate 44 and the second curved plate 41, respectively. The arrangement of the first and second curved plates improves the connection strength between the pile pipe support, the pile pipe, and the horizontal chord, making the connection structure between the pile pipe support and the pile pipe more stable.

[0031] Each pile driving pipe 2 is provided with a guide plate 21 on the side close to the seawater tower 1. In this embodiment, the guide plate 21 is connected to the pile driving pipe 2 by two side clamps 22, which are welded side by side to the outer wall of the pile driving pipe 2. The guide plate 21 is inserted between the two side clamps 22 and is detachably connected to the two side clamps 22 by a first bolt 23. The guide plate 21 and the two side clamps 22 cooperate to form a first through hole for the first bolt 23 to pass through. After passing through the first through hole, the first bolt 23 is threadedly connected with a matching first nut. By tightening the first nut, the guide plate 21 is fixed to the side clamp 22. When the guide plate is deformed or severely worn during later use, compared with conventional guide plates directly welded to the pile driving pipe, the replacement of the guide plate requires cutting and grinding of the weld. The guide plate of this solution is more convenient to replace and repair. At the same time, the side clamps on both sides clamp the guide plate, which improves the structural strength of the guide plate, reduces the probability of deformation of the guide plate, and extends the service life of the guide plate.

[0032] There are two guide assemblies 5, which are respectively arranged on both sides of the seawater tower 1. The guide assemblies 5 include a connecting piece and two sliding blocks 57. In this embodiment, the connecting piece includes a fixed connecting piece and a movable connecting piece.

[0033] The fixed connecting parts include a top plate 51, a bottom plate 52 and a second vertical plate 53. The second vertical plate 53 is arranged in the radial direction of the outside of the seawater tower 1. One side of the second vertical plate 53 is welded to the outer wall of the seawater tower 1. The top plate 51 and the bottom plate 52 are respectively welded to the two ends of the second vertical plate 53 and are perpendicular to the second vertical plate 53. The end faces of the top plate 51 and the bottom plate 52 close to the seawater tower 1 are arc-shaped surfaces that match the shape of the outer wall of the seawater tower 1. The arc-shaped surfaces of the top plate 51 and the bottom plate 52 are in contact with the outer wall of the seawater tower.

[0034] The movable connecting parts have two and are symmetrically arranged on both sides of the second vertical plate 53. Each movable connecting part includes a third vertical plate 54 and a fourth vertical plate 55 parallel to each other. The fourth vertical plate 55 is arranged on the side of the third vertical plate 54 away from the seawater tower 1, and is located on the side of the third vertical plate 54 away from the second vertical plate 53. The fourth vertical plate 55 is connected to the third vertical plate 54 as a whole through the second horizontal plate 56. The second horizontal plate 56 is vertically arranged in the middle of the third vertical plate 54. The two sides of the second horizontal plate 56 are welded to the third vertical plate 54 and the fourth vertical plate 55 respectively. The third vertical plates 54 of the two movable connecting parts are affixed to both sides of the second vertical plate 53 and are detachably connected to the second vertical plate 53 by second bolts 58. The third vertical plates 54 and the second vertical plates 53 of the two movable connecting parts are matched with a second through hole for the second bolt 58 to pass through. The second bolt 58 passes through the second through hole and is threadedly connected to the matching second nut. By tightening the second nut, the two movable connecting parts are fixed to the second vertical plate 53. The fourth vertical plates 55 of the two movable connectors cooperate to form a guide groove, and two sliding blocks 57 are respectively provided on the inner side walls of the fourth vertical plates 55 of the two movable connectors. If the sliding blocks become worn during later use, they can be easily replaced by simply removing the corresponding movable connector.

[0035] In this embodiment, the sliding block 57 is a cylindrical structure cut from round steel, which has a simple structure and is easy to process. The side of the sliding block 57 consists of a flat surface and a major arc surface. The flat surface of the sliding block 57 is aligned with the side wall of the fourth vertical plate 55, and a welding groove is automatically formed between the major arc surface and the side wall of the fourth vertical plate 55. The two sides of the major arc surface are welded to the side wall of the fourth vertical plate 55, thereby improving welding efficiency and welding quality. The guide plate 21 on the same side as the guide assembly is arranged between the two sliding blocks 57. The major arc surface of the sliding block is in linear contact with the side wall of the guide plate 21. This design changes the traditional surface contact between the flat steel and the guide plate to linear contact between the round steel and the guide plate, effectively reducing the friction between the sliding block and the guide plate, reducing the probability of jamming, and will not cause wear on the outer wall of the pile pipe. In addition, the structure is strong and not easy to damage.

[0036] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
