[0027] The following combines specific implementation cases and attachments Figures 1 to 4 to further illustrate the present utility model, but the present utility model is not limited to these embodiments.

[0028] Refer to Figures 1 to 4 As shown, a hoisting device for a positioning frame in water construction includes a positioning frame 18. The positioning frame 18 is a commonly used positioning frame in existing water construction, and its model is not limited here. It also includes a vertically arranged first vertical column 1. A through groove 2 is opened from left to right through the top end of the first vertical column 1. Two guide wheels 3 are respectively rotatably arranged up and down in the through groove 2 through bearings. The two guide wheels 3 form a guiding gap. A housing 4 is installed on the right side wall of the first vertical column 1. A driving component is arranged at the housing 4. The right side of the driving component is connected to a lifting seat 9. The lifting seat 9 is urged to move in the vertical direction through the driving component. One end of a linkage rod 19 is rotatably connected to the front side wall of the lifting seat 9 through a pin shaft. A cross plate 10 is vertically installed at the bottom end of the right side wall of the first vertical column 1. A moving seat 15 is arranged in parallel below the cross plate 10. The other end of the linkage rod 19 is rotatably connected to the front side wall of the moving seat 15 through a pin shaft. And the moving seat 15 is slidably arranged relative to the cross plate 10 in the horizontal direction through a sliding component. A fixing plate 16 is fixedly installed at the left end of the moving seat 15. An arc groove 17 is opened on the left side wall of the fixing plate 16; among them, the bottom end of the right side wall of the positioning frame 18 is attached to the inner wall of the arc groove 17;

[0029] As the lifting seat 9 moves downward, the top end of the linkage rod 19 is forced to move downward synchronously, and the bottom end of the linkage rod 19 is forced to drive the moving seat 15 to move leftward. As the moving seat 15 moves leftward, the fixing plate 16 and the arc groove 17 apply a leftward pushing force to the bottom end of the right side wall of the positioning frame 18. To force the bottom end of the positioning frame 18 to move leftward, and cooperate with the top end of the positioning frame 18 to achieve straightening and verticality.

[0030] Specifically, mainly refer to Figure 3As shown, the driving component includes a motor 5 installed on the housing 4, and further includes a guiding groove 6 vertically formed on the right side wall of the housing 4. The output end of the motor 5 is connected to a lead screw 7. The bottom end of the lead screw 7 is rotationally connected to the bottom end of the inner wall of the housing 4 through a bearing. A first slider 8 is threadedly sleeved on the lead screw 7, and the first slider 8 is slidably embedded in the inner cavity of the guiding groove 6. Among them, the right side wall of the first slider 8 is fixedly connected to the lifting seat 9. By starting the motor 5 to drive the lead screw 7, the rotation of the lead screw 7 causes the first slider 8 to move downward along the inner cavity of the guiding groove 6, so as to cause the lifting seat 9 to move downward, and drive the linkage rod 19 to drive the moving seat 15 to move.

[0031] Mainly refer to Figure 1 and Figure 3 As shown, a second slider 11 is fixedly installed on the right side wall of the lifting seat 9. A limiting rod 12 is vertically installed on the cross plate 10, and the second slider 11 is slidably sleeved on the limiting rod 12. When the lifting seat 9 moves, it drives the second slider 11 to move along the limiting rod 12 to ensure the stable upward or downward movement of the lifting seat 9.

[0032] Mainly refer to Figure 2 As shown, limiting grooves 13 are respectively formed on the front and rear side walls of the cross plate 10. Limiting blocks 14 are respectively slidably embedded in the limiting grooves 13. The bottom ends of the limiting blocks 14 are fixedly connected to the moving seat 15. The bottom end of the linkage rod 19 drives the moving seat 15 to move leftward. The moving seat 15 drives the limiting blocks 14 to move leftward along the inner cavity of the limiting grooves 13. Through the limiting cooperation of the limiting blocks 14 and the limiting grooves 13, it is ensured that the moving seat 15 moves in the horizontal direction. In addition, the shape of the limiting blocks 14 is set as an inverted L shape, so as to ensure that the limiting blocks 14 stably slide along the inner cavity of the limiting grooves 13 while the bottom ends of the limiting blocks 14 can be connected to the moving seat 15.

[0033] Mainly refer to Figure 1 and Figure 2As shown in the figure, at the top of the right side wall of the positioning frame 18, a first lifting ring 20 is installed. At the top of the lifting seat 9, a second lifting ring 21 is installed. A first lifting cable 22 is connected between the first lifting ring 20 and the second lifting ring 21. The first lifting cable 22 passes through the guiding gap formed by the two guiding wheels 3. As the lifting seat 9 descends, it causes the connection point of the first lifting cable 22 and the second lifting ring 21 to move downward, and the connection point of the first lifting cable 22 and the first lifting ring 20 to move upward and to the right. Thus, through the pulling of the first lifting cable 22 and the cooperation of the moving seat 15 moving to the left, the positioning frame 18 gradually becomes vertical within the arc-shaped groove 17 and is stabilized under the limiting action of the arc-shaped groove 17. At the top of the right side wall of the first upright column 1, a cross beam 23 is vertically installed. On the right side of the cross beam 23, a second upright column 25 is vertically installed, and the second upright column 25 is arranged parallel to the first upright column 1. At the bottom end of the second upright column 25, a weight 26 is installed. The weight 26 can ensure the stability when the equipment is placed vertically, and the connection between the equipment and the ground or the ship can be realized by means of the weight 26. A connecting column 24 is installed between the second upright column 25 and the cross plate 10. The first upright column 1, the cross beam 23, the second upright column 25, the connecting column 24, and the cross plate 10 form a stable framework, thereby ensuring that the equipment forms a stable structure and providing guarantee for the stable installation of other components.

[0034] In addition, two third lifting rings 27 are symmetrically installed on the left and right of the top of the cross beam 23. A second lifting cable 28 is connected between the two third lifting rings 27. By hoisting at the second lifting cable 28 with the help of existing hoisting equipment, the overall hoisting of this equipment is realized. The existing hoisting equipment can adopt the commonly used hoisting equipment for water construction on the market, and the model thereof is not limited herein.

[0035] It should be noted that in this application, the motor 5 adopts a self-locking motor commonly used on the market with an output end that can be locked. Its output end can be self-locked when it stops operating and will not rotate under external force. And the motor 5 is a commonly used forward and reverse motor on the market, and its output end can rotate forward or backward according to the usage requirements, and it can meet the above usage requirements. The lead screw 7 adopts a lead screw with a self-locking function on the market, and it can be locked when it stops rotating. There is no need to elaborate too much on the above existing components.

[0036] The working principle of a water construction positioning frame hoisting device in this embodiment is as follows:

[0037] Hook the hoisting hook at the second lifting cable 28 with the help of existing hoisting equipment, stably connect the left end of the first lifting cable 22 with the first lifting ring 20, stably connect the right end of the first lifting cable 22 with the second lifting ring 21, and make the first lifting cable 22 pass through between the two guiding wheels 3. In the initial state, the side wall of the positioning frame 18 is located within the arc-shaped groove 17 and contacts the inner wall of the arc-shaped groove 17.

[0038] The driving of the lead screw 7 by the activated motor 5 causes the lead screw 7 to rotate, which in turn prompts the first slider 8 to move downward along the inner cavity of the guiding groove 6, so as to cause the lifting seat 9 and the second slider 11 to move downward synchronously. At this time, the second slider 11 moves downward along the limiting rod 12 to ensure the stable downward movement of the lifting seat 9. As the lifting seat 9 moves downward, it prompts the top end of the linkage rod 19 to move downward synchronously, and causes the bottom end of the linkage rod 19 to drive the moving seat 15 to move leftward. The moving seat 15 drives the limiting block 14 to move leftward along the inner cavity of the limiting groove 13. Through the limiting cooperation of the limiting block 14 and the limiting groove 13, it ensures the horizontal movement of the moving seat 15. As the moving seat 15 moves leftward, it prompts the fixing plate 16 and the arc-shaped groove 17 to exert a leftward driving force on the bottom end of the right side wall of the positioning frame 18. At the same time, as the lifting seat 9 descends, it causes the connection point of the first sling 22 and the second sling ring 21 to move downward, and the connection point of the first sling 22 and the first sling ring 20 to move rightward and upward. Thus, through the cooperation of the pulling of the first sling 22 and the leftward movement of the moving seat 15, the positioning frame 18 gradually becomes vertical within the arc-shaped groove 17 and is stabilized under the limiting effect of the arc-shaped groove 17.

[0039] The utility model can ensure that the positioning frame 18 is in a vertical state after hoisting, which can ensure the direct progress of the construction and facilitate the direct, rapid and effective use of the positioning frame 18. Moreover, by using the same driving force, the linkage effect between the lifting seat 9 and the moving seat 15 can be realized, that is, the positioning frame 18 can be righted to a vertical state, avoiding the energy waste generated when multiple independent driving devices operate simultaneously, and significantly improving the coordination of the entire system.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
