Description

Technical Field

[0001] The present invention relates to the technical field of berth beam-slab transfer, and particularly to a crane ship for berth beam-slab transfer. Background Technique

[0002] In the high-piled wharf structure, beam-slab is often used to form the transverse bent and slab of the wharf to support and disperse the loads generated when ships berth. The structure needs to be carefully calculated and designed to ensure that it meets the requirements in terms of strength, stiffness, stability and durability. At the same time, factors such as the use function of the wharf, construction conditions and maintenance costs also need to be considered.

[0003] During the transfer process of berth beam-slab, a crane ship is used for transfer. However, there are still certain deficiencies in the actual use of the existing transfer crane ship: when the existing crane ship lifts the beam-slab, the chain is usually directly connected to the beam-slab. This makes the difference in rigidity between the chain and the flexibility of the berth beam-slab, and the connecting part may bear excessive concentrated force, resulting in local damage or deformation of the berth beam-slab, affecting subsequent installation and use. Based on the existing technical deficiencies, the present invention designs a crane ship for berth beam-slab transfer. Summary of the Invention

[0006] As a preferred technical solution of the present invention, a cantilever is fixedly installed on the top of the crane, a winding seat is fixedly installed on the top of the crane, and a first fixed pulley is rotatably installed inside the cantilever.

[0007] As a preferred technical solution of the present invention, a main chain is wound inside the winding seat, the main chain is in rolling connection with a first fixed pulley, a fixing member is fixedly installed at one end of the main chain, and the fixing member is fixedly connected with the mounting plate.

[0008] As a preferred technical solution of the present invention, anti-shake structures are fixedly installed on both sides of the outer surface of the cantilever. The two anti-shake structures include support arms and spring rollers.

[0009] As a preferred technical solution of the present invention, the two support arms are fixedly connected with the cantilever, and a second fixed pulley is rotatably installed inside the two support arms.

[0010] As a preferred technical solution of the present invention, the two spring rollers are rotatably connected with the cantilever, and auxiliary chains are wound inside the two spring rollers.

[0011] As a preferred technical solution of the present invention, the two auxiliary chains are in rolling connection with the second fixed pulley, and both ends of the bottoms of the two auxiliary chains are fixedly connected with the mounting plate.

[0012] As a preferred technical solution of the present invention, reinforcement structures are fixedly installed inside the four clamping rods. The four reinforcement structures include threaded rods and limiting rods.

[0013] As a preferred technical solution of the present invention, the four threaded rods are in threaded connection with the clamping rods, and hexagonal grooves are formed inside the four threaded rods.

[0014] As a preferred technical solution of the present invention, clamping plates are rotatably installed at the tops of the four threaded rods, the four limiting rods are movably connected with the clamping rods, and one ends of the four limiting rods are fixedly connected with the clamping plates.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. For the crane for hoisting and transporting berth beam slabs, through the fixing structure, when hoisting and transporting the berth beam slabs, the fixing structure is moved to both sides of the beam slab by the crane. At this time, the beam slab is located inside the clamping grooves of the two clamping rods on both sides. Subsequently, the two hydraulic cylinders on both sides are simultaneously driven, so that their telescopic rods drive the cross bar to move downward. Due to the hinges of the two first hinge rods and the two second hinge rods with the bending rod and the clamping rod, when the cross bar moves downward, the angles of the first hinge rod and the second hinge rod increase. At this time, the two clamping rods on both sides can be driven to move inward toward the mounting plate at the same time, so that the clamping rods can clamp and fix the berth beam slab. Thus, it is possible to avoid excessive concentrated force that may be borne by the connection part during the traditional hoisting process, resulting in local damage or deformation of the berth beam slab, and improving the safety of the device during transportation;

[0017] 2. The crane for transporting berth beam-slab can, through the anti-shaking structure, after the fixed structure clamps and fixes the berth beam-slab, make the main chain drive the whole fixed structure to move upward through the fixed part by winding of the winding seat. At the same time, due to the arrangement of the two spring rollers on both sides, the auxiliary chains can follow the main chain to wind at the same time. Thus, the main chain and the two auxiliary chains on both sides can lift the fixed structure simultaneously, ensuring that the fixed structure drives the berth beam-slab to remain stable during the rising process, avoiding the risk of dropping due to shaking, and improving the stability and safety of the berth beam-slab during the transportation process.

[0018] 3. The crane for transporting berth beam-slab can, through the reinforcement structure, after the clamping rod clamps and fixes the berth beam-slab, the staff can use a wrench to turn the four threaded rods. Due to the limitation of the limiting rod, the clamping plate can move horizontally upward when the threaded rods rotate. Thus, it can cooperate with the clamping rod to further fix the berth beam-slab, greatly improving the safety of the device during the transportation process. Description of the Drawings

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0029] Please refer to Figures 1-8 , a crane for transferring berth beam slabs, including a crane main body 1. A crane 2 is rotatably installed at the top of the crane main body 1, and a fixing structure 3 is arranged on one side of the crane 2; the fixing structure 3 includes a mounting plate 31. Hydraulic cylinders 32 are fixedly installed on both sides of the top of the mounting plate 31. The telescopic rods of the two hydraulic cylinders 32 pass through one end of the mounting plate 31 and are fixedly installed with a cross bar 34. Four side bending rods 33 are fixedly installed on both sides of the bottom of the mounting plate 31. Fixed sleeves 35 are fixedly installed on both sides of the outer surface of the two cross bars 34. One side of the outer surface of the four fixed sleeves 35 is hingedly installed with a first hinge rod 36, and the other side of the four fixed sleeves 35 is hingedly installed with a second hinge rod 37. One end of the four first hinge rods 36 is rotatably connected to the side bending rod 33, and clamping rods 38 are slidably installed inside the four side bending rods 33. The outer surfaces of the four clamping rods 38 are rotatably connected to one end of the second hinge rod 37.

[0030] Please refer to Figures 1-8 , a cantilever 21 is fixedly installed at the top of the crane 2, a winding seat 22 is fixedly installed at the top of the crane 2, and a first fixed pulley 23 is rotatably installed inside the cantilever 21. A main chain 24 is wound inside the winding seat 22. The main chain 24 is in rolling connection with the first fixed pulley 23. One end of the main chain 24 is fixedly installed with a fixing piece 25, and the fixing piece 25 is fixedly connected to the mounting plate 31.

[0031] Driven by the winding seat 22, the main chain 24 can drive the mounting plate 31 to move upward through the first fixed pulley 23 and the fixing piece 25.

[0032] Please refer to Figures 1-4 , anti-shaking structures 4 are fixedly installed on both sides of the outer surface of the cantilever 21. The two anti-shaking structures 4 include support arms 41 and spring rollers 42. The two support arms 41 are fixedly connected to the cantilever 21, and a second fixed pulley 43 is rotatably installed inside the two support arms 41. The two spring rollers 42 are rotatably connected to the cantilever 21, and auxiliary chains 44 are wound inside the two spring rollers 42. The two auxiliary chains 44 are in rolling connection with the second fixed pulley 43, and both ends of the bottom of the two auxiliary chains 44 are fixedly connected to the mounting plate 31.

[0033] By winding the winding seat 22, the main chain 24 can drive the entire fixing structure 3 to move upward through the fixing member 25. At the same time, due to the arrangement of the two side spring rollers 42, the auxiliary chain 44 can follow the main chain 24 to wind simultaneously. Thus, the main chain 24 and the two side auxiliary chains 44 can lift the fixing structure 3 at the same time, ensuring that the fixing structure 3 drives the berth beam slab to remain stable during the rising process.

[0034] Please refer to Figures 6-8 , a reinforcing structure 5 is fixedly installed inside the four clamping rods 38. The four reinforcing structures 5 include threaded rods 51 and limiting rods 53. The four threaded rods 51 are threadedly connected to the clamping rods 38, and hexagonal grooves are formed inside the four threaded rods 51. Clamping plates 52 are rotatably installed at the tops of the four threaded rods 51, the four limiting rods 53 are movably connected to the clamping rods 38, and one ends of the four limiting rods 53 are fixedly connected to the clamping plates 52.

[0035] After the clamping rods 38 clamp and fix the berth beam slab, the staff uses a wrench to turn the four threaded rods 51. Due to the limitation of the limiting rods 53, the clamping plates 52 can move horizontally upward when the threaded rods 51 rotate. Thus, it can cooperate with the clamping rods 38 to further fix the berth beam slab.

[0036] Working principle: When a hoisting ship for transporting berth beam slabs is in use, first, by winding the winding seat 22, the main chain 24 can drive the entire fixing structure 3 to move through the fixing member 25. The fixing structure 3 is moved to both sides of the beam slab by the crane 2. At this time, the beam slab is located inside the clamping grooves of the two side clamping rods 38. Subsequently, the two side hydraulic cylinders 32 are simultaneously driven, and their telescopic rods drive the cross bar 34 to move downward. Due to the hinges of the two side first hinge rods 36 and the two side second hinge rods 37 with the bending rod 33 and the clamping rods 38, when the cross bar 34 moves downward, the angles of the first hinge rod 36 and the second hinge rod 37 increase. At this time, the two side clamping rods 38 can be driven to move inward into the mounting plate 31 simultaneously. Thus, the clamping rods 38 can clamp and fix the berth beam slab. Then, the staff uses a wrench to turn the four threaded rods 51. Due to the limitation of the limiting rods 53, the clamping plates 52 can move horizontally upward when the threaded rods 51 rotate. Thus, it can cooperate with the clamping rods 38 to further fix the berth beam slab. Finally, by winding the winding seat 22, the main chain 24 can drive the entire fixing structure 3 to move upward through the fixing member 25. At the same time, due to the arrangement of the two side spring rollers 42, the auxiliary chain 44 can follow the main chain 24 to wind simultaneously. Thus, the main chain 24 and the two side auxiliary chains 44 can lift the fixing structure 3 at the same time, ensuring that the fixing structure 3 drives the berth beam slab to remain stable during the rising process.
