Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water terminal operation, in particular to a cantilever platform for wharf construction and its erection method. BACKGROUND

[0002] As a part of water conservancy projects, water terminals need to rely on building infrastructure during daily operation. For example, when building a water terminal near a river, it may need to be combined with embankments, revetments and other building structures on the shore to enhance the stability and erosion resistance of the terminal. However, over time, the outer wall of the terminal near the river may be damaged due to weathering factors. At this time, a cantilever platform is needed to maintain the construction of the terminal near the river. During the use of the cantilever platform, safety is of utmost importance. If the cantilever platform is not safe, it may fall and threaten the safety of workers on the platform.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application No. 202222507768.0, filed on September 21, 2022) provides a cantilever platform for terminal construction. When in use, the platform trolley is limited by the limiting assembly and the limiting rail, thereby avoiding safety hazards caused by the platform trolley extending too far beyond the cantilever platform. In addition, the protective structure is provided to buffer and limit the falling construction basket when the winch fails or the steel wire rope breaks, thereby ensuring the safety of the construction basket during use.

[0004] During the operation of the cantilever platform, it moves in the vertical direction and relies on steel wire ropes or traction chains.

[0022] (1) The cantilever platform used for the wharf construction, during use, is driven by a driving motor to rotate the connecting shaft, thereby realizing the recovery and release of the traction chain, so that the mobile platform moves in the vertical direction under the action of the traction chain and the guide rod, allowing the staff to repair the outer wall of the wharf facing the river.

[0024] (2) The cantilever platform used for the construction of the wharf has a cleaning block and a cleaning pipe that clean the traction chain during the recovery and release process, sweeping away dust and other impurities on the surface of the traction chain and reducing the probability of corrosion of the traction chain.

[0025] Furthermore, during the movement of the movable plate, the vertical rod inside the movable plate moves synchronously, and the force-bearing block on the surface of the vertical rod will intermittently contact the pushing block. Then, the vertical rod and the force-bearing block make reciprocating linear motion in the horizontal direction under the action of thrust, cross rod and connecting spring, and the traction chain can be better cleaned by the cleaning block and cleaning tube, thereby optimizing the cleaning effect.

[0026] Furthermore, when the cleaning tube moves in the horizontal direction, it also rotates back and forth inside the cleaning block, and at this time the cleaning tube can better wipe the drag chain.

[0045] In use, the connecting shaft 3 is driven to rotate by the driving machine 2, thereby realizing the recovery and release of the traction chain 6, so that the mobile platform 4 moves in the vertical direction under the action of the traction chain 6 and the guide rod 5, so that the worker can perform building maintenance on the wharf river wall, and when the connecting shaft 3 rotates, the connecting shaft 3 drives the long pin 8 to rotate through the main gear 9 and the secondary gear 10, and then the long pin 8 cooperates with the limiting rod 13 to make the movable plate 12 move synchronously in the horizontal direction, and then the movable plate 12 can drive the traction chain 6 to move, so that the traction chain 6 is uniformly wound on the connecting shaft 3, and the safety is improved, and the upper surface of the fixed rod 7 is provided with an oil supplement box, which can supplement the surface of the traction chain 6 with corrosion inhibitor and lubricating oil, and ensure the working efficiency of the traction chain 6.

[0046] Example two: different from example one, the vertical rod 15 and the cleaning block 16 are arranged, so that the surface of the traction chain 6 can be cleaned, as shown in Figures 4-9 The inside of the movable plate 12 is connected with the vertical rod 15 through the moving mechanism, the inside of the vertical rod 15 is inserted with the cleaning block 16; the moving mechanism includes the horizontal rod 20 fixedly connected to the inner wall of the movable plate 12, the surface of the horizontal rod 20 is sleeved with the vertical rod 15, the upper surface of the movable plate 12 is recessed, the surface of the vertical rod 15 is fixedly connected with the stress block 18, the inner wall of the support 1 is fixedly connected with the connecting plate 14, the surface of the connecting plate 14 is fixedly connected with the pushing block 19, and the pushing block 19 is distributed on the surface of the connecting plate 14 at equal intervals.

During the movement of the movable plate 12, the vertical rod 15 inside the movable plate 12 moves synchronously, and then the stress blocks 18 on the surface of the vertical rod 15 intermittently contact the pushing blocks 19 on the surface of the connecting plate 14. When the pushing blocks 19 push the stress blocks 18, the vertical rod 15 moves in the direction of pressing the connecting spring 21 under the action of the cross rod 20.
