Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy wharf operations, and particularly to a cantilever platform for wharf construction and its erection and use method. Background Art

[0002] As a part of water conservancy projects, water conservancy wharves need to rely on building foundations during daily operation. For example, when constructing water conservancy wharves facing the river, they may need to be combined with building structures such as river embankments and revetments on the shore to enhance the stability and anti-scouring ability of the wharf using the foundation of the building. During long-term use, the outer wall position of the wharf facing the river will be damaged due to weathering factors. At this time, a cantilever platform is needed to carry out building repairs on the position of the wharf facing the river. During the use of the cantilever platform, safety is of utmost importance. If the safety of the cantilever platform is low and it falls, it will threaten the lives of the workers on the cantilever platform.

[0003] In order to overcome the above defects, a prior art (Chinese patent application with application number 202222507768.0 and application date September 21, 2022) is a cantilever platform for wharf construction. When it works, by setting a limiting component, the platform trolley is limited by a limiting barrier, thus avoiding potential safety hazards caused by the platform trolley extending too far out of the cantilever platform. Moreover, a protective structure is provided. When accidents such as the failure of the winch or the fracture of the steel wire rope occur, the falling construction hanging basket is buffered and limited by a buffer spring, thus well ensuring the safety of the construction hanging basket during use.

[0004] During the working process of the cantilever platform, it will move in the vertical direction and thus needs to rely on the work of the steel wire rope or the traction chain. However, the cantilever platform in the above application does not have the function of evenly winding and collecting the traction chain during use. Therefore, during use, the traction chain may become entangled and piled up, bringing inconvenience to the subsequent work of the cantilever platform. At the same time, during use, dust and other impurities will accumulate on the traction chain, and these impurities will corrode the traction chain. The cantilever platform in the above application does not have a structure for assisting in impurity removal during the working process. Therefore, after long-term use, the traction chain is corroded by impurities, and the overall safety of the cantilever platform will be greatly reduced, bringing great safety hazards to the cantilever platform and the workers. Summary of the Invention

[0005] The purpose of the present invention is to provide a cantilever platform for dock construction and its erection and use method, so as to solve the problems raised in the above background technology. During the use process, it does not have the function of evenly winding and collecting the traction chain. Therefore, during the use process, it may cause inconvenience to the subsequent work of the cantilever platform due to the winding and accumulation of the traction chain. And because it does not have a structure for auxiliary impurity removal, after long-term use, the traction chain is corroded by impurities, and the overall safety of the cantilever platform will be greatly reduced, bringing great potential safety hazards to the cantilever platform and the staff.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

A vertical rod is connected to the inside of the movable plate through a moving mechanism, and a cleaning block is inserted into the vertical rod. The bottom plate is fixedly connected to the outer wall of the dock, and a buffer mechanism is arranged inside the bottom plate. The buffer mechanism includes a sliding plate slidably arranged inside the bottom plate.

[0008] Preferably, the side of the moving platform is convex. A fixed rod is fixedly connected to the lower surface of the bracket, and the front view of the fixed rod is an inverted "L" structure. The traction chain is movably arranged inside the fixed rod.

[0009] Preferably, the reciprocating mechanism includes a main gear fixedly connected to the surface of the connecting shaft, a sub-gear fixedly connected to the surface of the long pin, and the sub-gear is meshed with the main gear. An auxiliary rod is rotatably connected to the inner wall of the bracket, and the surface of the auxiliary rod is in contact with the surface of the traction chain.

[0010] Preferably, the long pin is threadedly connected to the movable plate. A limiting rod is fixedly connected to the inner wall of the bracket, and the limiting rod passes through the inside of the movable plate, and the limiting rod is slidably connected to the movable plate.

[0011] Preferably, the moving mechanism includes a cross bar fixedly connected to the inner wall of the movable plate, and the vertical rod is sleeved and connected to the surface of the cross bar. The upper surface of the movable plate is concave.

[0012] Preferably, a stress block is fixedly connected to the surface of the vertical rod, a connecting plate is fixedly connected to the inner wall of the bracket, a pushing block is fixedly connected to the surface of the connecting plate, and the pushing blocks are equidistantly distributed on the surface of the connecting plate. An upper connecting rod is inserted into the upper surface of the movable plate, and bumps are fixedly connected to the inner wall of the upper connecting rod at equal intervals, and the bumps are distributed vertically and alternately on the inner wall of the upper connecting rod.

[0013] Preferably, the surfaces of the stress block and the pushing block are both arc-shaped structures. A connecting spring for elastic reset is fixedly connected to the surface of the vertical rod, and the other side of the connecting spring is fixedly connected to the inner wall of the movable plate. A plug rod is fixedly connected to the lower surface of the cleaning block, a jack corresponding to the plug rod one by one is opened on the upper surface of the vertical rod, a guiding rod is fixedly connected to the inner wall of the cleaning block, a cleaning pipe is movably arranged inside the cleaning block, and a guiding groove is opened on the surface of the cleaning pipe. A working block is fixedly connected to the surface of the cleaning pipe.

[0014] Preferably, the buffer mechanism further includes an inner rod fixedly connected to the inner wall of the bottom plate. A sliding plate is sleeved on the surface of the inner rod, and a rotating shaft is rotatably arranged on the upper surface of the sliding plate. An auxiliary plate is sleeved on the surface of the rotating shaft.

[0015] Preferably, a buffer plate is movably arranged on the upper surface of the auxiliary plate, and the buffer plate is horizontally arranged. A reset spring for elastic reset is fixedly connected to the surface of the sliding plate, and the other side of the reset spring is fixedly connected to the inner wall of the bottom plate. A damping rod is arranged between the sliding plate and the bottom plate.

[0016] A method for erecting and using a cantilever platform for wharf construction includes the following steps:

[0017] S1: The driving machine drives the connecting shaft to rotate, thereby realizing the recycling and release of the traction chain. Under the action of the traction chain and the guiding rod, the mobile platform moves in the vertical direction, enabling the staff to repair the outer wall of the wharf facing the river. When the connecting shaft rotates, the connecting shaft drives the movable plate to move synchronously in the horizontal direction through the reciprocating mechanism. Then, the movable plate can drive the traction chain to move, so that the traction chain is evenly wound around the connecting shaft.

[0018] S2: During the working process of the traction chain, the cleaning block makes a reciprocating linear motion in the horizontal direction under the action of the moving mechanism, so that the traction chain can be better cleaned by the cleaning block, optimizing the cleaning effect.

[0019] S3: When the mobile platform descends rapidly, the lower end of the mobile platform will first contact the buffer plate. At this time, the buffer plate pushes the sliding plate through the auxiliary plate. Then, the sliding plate plays a role of buffer protection through the reset spring, the inner rod and the damping rod.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The cantilever platform for the wharf construction adopts a new structural design. Through the reciprocating movable plate, the traction chain can be evenly wound on the connecting shaft, and the traction chain will not be piled up, which improves safety. In addition, a reciprocating cleaning block and a cleaning pipe are set inside the movable plate, so that the cleaning pipe can clean the impurities on the surface of the traction chain, reducing the probability of the traction chain being corroded, further improving safety. On the outer wall of the wharf, a bottom plate and a buffer plate are set. The buffer plate cooperates with the reset spring and the damping rod, so that the mobile platform can be greatly self-protected when working, and no work accidents will occur. The specific contents are as follows:

[0022] (1) During the use of the cantilever platform for wharf construction, the driving machine drives the connecting shaft to rotate, 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 guide rod, allowing workers to repair the riverside outer wall of the wharf.

[0023] Furthermore, when the connecting shaft rotates, the connecting shaft drives the long pin to rotate through the main gear and the sub-gear, and then the long pin cooperates with the limit rod to make the movable plate move synchronously in the horizontal direction, and then the movable plate can drive the traction chain to move, so that the traction chain is evenly wound on the connecting shaft, and the traction chain will not accumulate, thereby improving safety.

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

[0025] Furthermore, during the movement of the movable plate, the vertical rods inside the movable plate move synchronously, and the force blocks on the surfaces of the vertical rods will intermittently contact the pushing blocks. Then, the vertical rods and the force blocks make reciprocating linear motion in the horizontal direction under the action of thrust, cross rods and connecting springs, and the traction chain can be better cleaned by the cleaning blocks and cleaning tubes, thereby optimizing the cleaning effect.

[0026] Furthermore, when the cleaning tube moves in the horizontal direction, it will also reciprocate inside the cleaning block, and at this time, the cleaning tube can better wipe the traction chain.

[0027] (3) The cantilever platform used for the construction of the wharf, when the mobile platform descends rapidly, the lower end of the mobile platform will first contact the buffer plate. At this time, the buffer plate pushes the sliding plate through the auxiliary plate, and then the sliding plate plays a buffering and protective role through the return spring and damping rod, thereby improving safety. In this process, the inner rod makes the sliding plate move only in the horizontal direction, thereby improving stability. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] The present invention provides the following technical solution: a cantilever platform for dock building construction and its erection and use method.

[0043] Embodiment 1: By setting the movable plate 12, the traction chain 6 can be evenly wound, as Figures 1 - 4 and Figure 9 shown, including a bracket 1, a moving platform 4, a guide rod 5 and a bottom plate 23. The bracket 1 is fixedly connected to the edge position of the dock, and a connecting shaft 3 is rotatably arranged inside the bracket 1. The brackets 1 are symmetrically distributed on both sides of the connecting shaft 3, and a driving machine 2 is fixedly connected to the surface of the inner bracket 1. The guide rod 5 is fixedly connected to the outer wall of the dock, and a moving platform 4 is slidably arranged on the surface of the guide rod 5. The traction chain 6 is wound and fixedly connected to the surface of the connecting shaft 3, and the end of the traction chain 6 is fixedly connected to the side of the moving platform 4. A long pin 8 is rotatably arranged inside the bracket 1, and a movable plate 12 for evenly winding the wire is connected to the surface of the long pin 8 through a reciprocating mechanism. The bottom plate 23 is fixedly connected to the outer wall of the dock.

[0044] The side of the moving platform 4 is convex. A fixing rod 7 is fixedly connected to the lower surface of the bracket 1, and the front view of the fixing rod 7 is an inverted "L" structure. The traction chain 6 is movably arranged inside the fixing rod 7. The reciprocating mechanism includes a main gear 9 fixedly connected to the surface of the connecting shaft 3, a sub-gear 10 fixedly connected to the surface of the long pin 8, and the sub-gear 10 is meshed with the main gear 9. An auxiliary rod 11 is rotatably connected to the inner wall of the bracket 1, and the surface of the auxiliary rod 11 is attached to the surface of the traction chain 6. The long pin 8 is threadedly connected to the movable plate 12. A limiting rod 13 is fixedly connected to the inner wall of the bracket 1, and the limiting rod 13 penetrates through the inside of the movable plate 12, and the limiting rod 13 is slidably connected to the movable plate 12.

[0045] During use, the driving machine 2 drives the connecting shaft 3 to rotate, thereby realizing the recovery and release of the traction chain 6. Under the action of the traction chain 6 and the guide rod 5, the mobile platform 4 moves in the vertical direction, enabling the staff to perform building maintenance on the outer wall of the dock facing the river. When the connecting shaft 3 rotates, the connecting shaft 3 drives the long pin 8 to rotate through the main gear 9 and the auxiliary gear 10. Furthermore, the long pin 8 cooperates with the limiting rod 13, causing the movable plate 12 to move synchronously in the horizontal direction. Then, the movable plate 12 can drive the traction chain 6 to move, so that the traction chain 6 is evenly wound around the connecting shaft 3, and the situation of the traction chain 6 piling up will not occur, improving safety. The upper surface of the fixed rod 7 is fixedly provided with an oil replenishing box, which can replenish anti-corrosive agent and lubricating oil to the surface of the traction chain 6, ensuring the working efficiency of the traction chain 6.

[0046] Embodiment 2: Different from Embodiment 1, through the provided vertical rod 15 and cleaning block 16, the surface of the traction chain 6 can be cleaned. As Figures 4 - 9 shown, the vertical rod 15 is connected to the inside of the movable plate 12 through a moving mechanism, and the cleaning block 16 is inserted into the vertical rod 15; the moving mechanism includes a cross rod 20 fixedly connected to the inner wall of the movable plate 12, and the vertical rod 15 is sleeved and connected to the surface of the cross rod 20. Moreover, the upper surface of the movable plate 12 is concave. A force receiving block 18 is fixedly connected to the surface of the vertical rod 15, a connecting plate 14 is fixedly connected to the inner wall of the support 1, and a pushing block 19 is fixedly connected to the surface of the connecting plate 14, and the pushing blocks 19 are equally spaced on the surface of the connecting plate 14.

[0047] The surfaces of the force receiving block 18 and the pushing block 19 are both arc-shaped structures. A connecting spring 21 for elastic reset is fixedly connected to the surface of the vertical rod 15, and the other side of the connecting spring 21 is fixedly connected to the inner wall of the movable plate 12. A plug rod 17 is fixedly connected to the lower surface of the cleaning block 16, and insertion holes corresponding to the plug rod 17 one by one are opened on the upper surface of the vertical rod 15. An upper connecting rod 30 is inserted into the upper surface of the movable plate 12, and bumps 31 are fixedly connected at equal intervals on the inner wall of the upper connecting rod 30, and the bumps 31 are staggered up and down on the inner wall of the upper connecting rod 30. A guiding rod 32 is fixedly connected to the inner wall of the cleaning block 16, and a cleaning pipe 33 is movably arranged inside the cleaning block 16, and a guiding groove 34 is opened on the surface of the cleaning pipe 33. A working block 35 is fixedly connected to the surface of the cleaning pipe 33.

[0048] During the recycling and release of the traction chain 6, the cleaning pipe 33 plays a role in cleaning the traction chain 6, sweeping off dust and other impurities on the surface of the traction chain 6, reducing the probability of corrosion of the traction chain 6. During the movement of the movable plate 12, the vertical rod 15 inside the movable plate 12 moves synchronously. Furthermore, the force-bearing block 18 on the surface of the vertical rod 15 will intermittently contact the pushing block 19 on the surface of the connecting plate 14. When the pushing block 19 pushes the force-bearing block 18, the vertical rod 15 moves in the direction of squeezing the connecting spring 21 under the action of the cross rod 20. When the pushing block 19 does not contact the force-bearing block 18, the vertical rod 15 moves back under the action of the connecting spring 21. Repeating the above process, the vertical rod 15 and the force-bearing block 18 perform a reciprocating linear motion in the horizontal direction under the action of the thrust force, the cross rod 20, and the connecting spring 21. Thus, the traction chain 6 can be better cleaned by the cleaning pipe 33.

[0049] During the movement of the cleaning pipe 33, the convex blocks 31 on the inner wall of the upper connecting rod 30 will intermittently contact the working block 35. The convex blocks 31 are arranged in a vertically staggered structure. Thus, the working block 35 will be intermittently pushed. At this time, the working block 35 will drive the cleaning pipe 33 to swing inside the cleaning block 16. Therefore, the cleaning pipe 33 not only moves in the horizontal direction but also rotates, optimizing the cleaning effect. During the operation of the cleaning pipe 33, the guiding groove 34 and the guiding rod 32 play a role in limiting and guiding, improving the working stability of the cleaning pipe 33. The cleaning block 16 is connected to the vertical rod 15 through the inserting rod 17 and the inserting hole. Thus, after long-term use, the cleaning block 16 can be directly replaced, ensuring the working efficiency of the cleaning block 16.

[0050] Embodiment 3: Different from Embodiment 2, the buffer plate 22 and the reset spring 29 are provided to play a role in buffer protection. As Figures 10 - 12 shown, a buffer mechanism is arranged inside the bottom plate 23. The buffer mechanism includes a sliding plate 25 slidably arranged inside the bottom plate 23. The buffer mechanism further includes an inner rod 24 fixedly connected to the inner wall of the bottom plate 23. The surface of the inner rod 24 is sleeved and connected with the sliding plate 25. A rotating shaft 26 is rotatably arranged on the upper surface of the sliding plate 25. The surface of the rotating shaft 26 is sleeved and connected with an auxiliary plate 27. A buffer plate 22 is movably arranged on the upper surface of the auxiliary plate 27, and the buffer plate 22 is horizontally arranged. A reset spring 29 that plays an elastic reset role is fixedly connected to the surface of the sliding plate 25, and the other side of the reset spring 29 is fixedly connected to the inner wall of the bottom plate 23. A damping rod 28 is arranged between the sliding plate 25 and the bottom plate 23.

[0051] When the mobile platform 4 descends rapidly, the lower end of the mobile platform 4 will first come into contact with the buffer plate 22. At this time, the buffer plate 22 pushes the sliding plate 25 through the auxiliary plate 27. Then, the sliding plate 25 moves horizontally through the damping rod 28 and the inner rod 24. At this time, the return spring 29 is compressed. The return spring 29 and the damping rod 28 play a role in buffer protection, improving safety. When the mobile platform 4 rises again, the return spring 29 and the damping rod 28 push the sliding plate 25 back to its original position. Then, the buffer plate 22 rises to its original position under the action of the auxiliary plate 27, facilitating the next use of the buffer plate 22, the auxiliary plate 27 and the sliding plate 25.

[0052] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
