Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of floating platforms, in particular to a pulley counterweight structure for a pontoon platform.
Background Art
[0002] As a water facility, the design and construction of a floating platform need to consider various factors, including but not limited to buoyancy, stability, safety, and usability. Counterweight is an important part of the floating platform design, aiming to ensure that the floating platform can maintain stable buoyancy and good stability on the water surface, so as to provide a safe and comfortable use environment.
[0003] One of the key factors for a floating platform to maintain stability in an environment with a large water level drop is the counterweight, which can help the floating platform maintain balance when the water level changes. By reasonably configuring the counterweight, the stability of the floating platform can be increased, preventing tilting or capsizing caused by water level changes. The currently common practice is to use water weight adjustment, by injecting water into the floating platform to increase its self-weight, or discharging water to reduce its self-weight. If manual operation is adopted, it is time-consuming and laborious. If an electric control system is added, the cost will increase.
[0004] In view of the above problems, the applicant has proposed a solution.

The pair of anchor foundation blocks are anchored to the underwater bottom layer and symmetrically arranged on both sides of the pontoon platform in the top view direction. A pair of fixed pulley groups are symmetrically fixed to the bottom of the pontoon platform. One end of the anchor rope is fixedly connected to the anchor foundation block, and the other end passes upward around the fixed pulley of the oppositely arranged fixed pulley group and is fixedly connected to the counterweight.

[0028] The utility model provides a pulley counterweight structure for a pontoon platform, which comprises Figure 1 , 2 As shown in Fig. 3, it includes a pontoon platform 10, and at least one set of pulley counterweight anchoring groups are arranged with the pontoon platform 10; each pulley counterweight anchoring group includes a pair of anchor foundation 20, a pair of fixed pulley groups 30, a pair of counterweights 40 and a pair of anchor ropes 50. The pair of anchor foundation 20 are anchored to the underwater bottom layer and are symmetrically arranged on both sides of the pontoon platform 10 in the top view direction. A pair of fixed pulley groups 30 are symmetrically fixed to the bottom of the pontoon platform 10. One end of the anchor rope 50 is fixedly connected to the anchor foundation 20, and the other end is upwardly wound around the fixed pulley of the fixed pulley group 30 arranged oppositely and then fixedly connected to the counterweight 40. The pair of anchor ropes 50 are cross - arranged, that is, one side of the anchor foundation 20 is connected to the fixed pulley group 30 on the other side.
[0029] Since the anchor foundation 20 is fixed, when the pontoon platform 10 fluctuates up and down with the water level, the fixed pulley group 30 fixed to its bottom fluctuates up and down with it. However, under the pulling action of the counterweight 40, the balance of gravity is achieved, playing a role in gravity adjustment, greatly improving the stability of the pontoon platform 10 and ensuring the balance of the pontoon platform 10.
[0030] In the first embodiment, as Figure 2 shown, the anchor rope 50 is directly fixedly connected to the counterweight 40 after passing around the fixed pulley group 30. A section of the anchor rope 50 between the fixed pulley group 30 and the counterweight 40 is vertically arranged. Since the anchor ropes 50 are cross - arranged, a section of the anchor rope 50 between the anchor foundation 20 and the fixed pulley group 30 is inclined. In this case, on the one hand, the two - way force balance is unstable, and on the other hand, the vertical pulling force on the fixed pulley group 30 is too large, and the fixed pulley group 30 is easily damaged.
[0031] In the second embodiment, as Figure 3 shown, a movable pulley group 60 with a movable pulley is fixedly connected to the other end of the anchor rope 50 far from the anchor foundation 20. The counterweight 40 is fixedly connected to the bottom of the movable pulley group 60. A section of the anchor rope 50 between the anchor foundation 20 and the fixed pulley group 30 is slidably connected to the movable pulley group 60. Specifically, as Figure 5 shown, the movable pulley group 60 includes a movable pulley frame 61, and a pair of movable pulleys 62 arranged up and down are arranged in the movable pulley frame 61. A section of the anchor rope 50 between the anchor foundation 20 and the fixed pulley group 30 is placed between the pair of movable pulleys 62. In this embodiment, a section of the anchor rope 50 between the fixed pulley group 30 and the movable pulley group 60 is parallel to a section of the anchor rope 50 between the anchor foundation 20 and the fixed pulley group 30, and the two - way moment reaches balance, and the balance adjustment is better.
[0032] In some embodiments of the present utility model application, such as Figure 2 , 3 , as shown in Figure 4, the fixed pulley set 30 includes a connecting seat 31 provided with a fixed pulley and a connecting bolt. The connecting seat 31 is fixedly connected to the bottom of the connecting bolt, and the connecting bolt is upwardly connected to be anchorable in the middle of the floating platform 10.
[0033] In some embodiments of the present utility model application, such as Figure 4 , as shown in the figure, the connecting bolt includes an anchor rod 32. The lower end of the anchor rod 32 abuts against the bottom of the floating platform 10, and its upper end abuts against the upper part of the floating platform 10. The anchor rod 32 is fixedly connected to the connecting seat 31 at its lower end. A screw tube 33 is fixed at the upper end of the anchor rod 32. The screw tube 33 extends upwardly out of the upper edge of the floating platform 10, and a positioning assembly for positioning and installing on the upper part of the floating platform 10 is provided on the screw tube 33. The positioning assembly includes a positioning disc 34 and a positioning nut 35. The positioning disc 34 is sleeved on the screw tube 33, and the positioning nut 35 is locked onto the screw tube 33 in cooperation.
[0034] Since the size of the floating platform 10 is uncertain, for a relatively small floating platform 10 in a still water area, two or three sets of pulley counterweight anchoring groups can be configured. However, for a relatively large floating platform 10, strengthening configuration is required. As Figure 1 shown in the figure, the pulley counterweight anchoring group includes multiple sets. The floating platform 10 includes a first floating platform 11 and a second floating platform 12 connected to the first floating platform 11. Multiple sets of pulley counterweight anchoring groups are arranged along the length direction of the first floating platform 11 and / or along the length direction of the second floating platform 12.
[0035] Although the present utility model has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present utility model without departing from the principle and spirit scope of the present utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present utility model, and the scope of protection is defined by the content of the claims.
