The winch and the fixed pulley block are arranged on the pool wall, the hanging bracket and the movable pulley block are arranged on two sides of the ship bearing platform, and the steel wire rope penetrates through the fixed pulley block and the movable pulley block to connect the winch and the ship bearing platform together and realize the functions of reinforcement and speed reduction. For the ship lift, the ship bearing platform, the movable pulley block and the hanging bracket are always in the water area of the harbor basin and are in the working condition of the water area on site, and the installation and the removal work are difficult to carry out under the construction condition.
In the prior art, the hanger is provided with a circular hole for penetrating the shaft, the shaft is provided with the bearing and the pulley, the mounting and the maintenance are difficult, the hanger is positioned in the groove of the harbor basin, one end of the hanger is connected with the ship bearing platform, the operation space is very limited, and the difficulty in mounting and dismounting the movable pulley block on the hanger is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the not enough movable pulley gallows structure dismantled of a ship lift that designs to prior art, adopt the end opening for open movable pulley gallows structure, the integral erection or the dismantlement of the movable pulley group part of being convenient for send into the workshop and do the maintenance, have improved its maintainability greatly, and gallows simple structure makes things convenient for the repair and the maintenance of the axle of movable pulley group, spare parts such as bearing, pulley greatly, further improves the security performance and the work efficiency of ship lift.
The purpose of the utility model is realized like this: a detachable movable pulley hanger structure of a ship lift comprises a plurality of movable pulleys arranged on a movable pulley shaft through movable pulley bearings, and is characterized in that connecting plates are respectively arranged on two sides of each movable pulley, and the lower ends of the connecting plates are provided with shaft holes with U-shaped openings; the movable pulleys and the movable pulley bearings are arranged on the movable pulley shafts in a one-to-one correspondence mode, shaft end baffles fixed by screws are arranged at two ends of each movable pulley, and the movable pulleys are arranged on the movable pulley shafts and are detachable movable pulley hanger integral parts.
The shaft hole is provided with a U-shaped reinforcing ring, and the lower end opening is provided with a trapezoidal reinforcing plate.
Compared with the prior art, the utility model have simple structure, easily installation demolishs the back, can send into the workshop and do the maintenance, has improved its maintainability, and the repair and the maintenance of the axle of the running block of being convenient for, spare parts such as bearing, pulley further reduce equipment dimension guarantor cost, improve work efficiency and economic benefits.

Detailed Description
Referring to fig. 1-2, the utility model discloses constitute by a plurality of movable pulleys 6 and movable pulley bearing 5 and connecting plate 3, movable pulley axle 4, movable pulley 6 sets up on movable pulley axle 4 for the one-to-one with movable pulley bearing 5, and its both ends are equipped with the axle baffle 7 of fix with screw, set up a plurality of movable pulleys 6 on movable pulley axle 4, assemble detachable movable pulley gallows whole part.
Referring to fig. 3, the lower end of the connecting plate 3 is provided with a shaft hole 8 with a U-shaped opening, the shaft hole 8 is provided with a U-shaped reinforcing ring 9, and the lower end opening is provided with a trapezoidal reinforcing plate.
The invention will be described and illustrated in further detail below with reference to a ship lift as an example:
example 1
Referring to fig. 4, ship platform 1 of ship lift sets up in the waters of harbor basin 11, will the utility model discloses a welding of movable pulley gallows structure is at ship platform 1's both ends, movable pulley gallows structure is welded by a plurality of connecting plates 3 and ship platform 1's end plate 1 and is become integrative, and a plurality of movable pulleys 6 are connected by wire rope 14 and the hoist engine that sets up hoisting point device 13 on the pool wall, realize that ship platform 1 promotes or descends.
Referring to the attached drawing 5, the utility model discloses install in the recess 12 of harbor basin 11, a plurality of connecting plates 3 and end plate 1 weld an organic whole, and connecting plate 3 supports a plurality of movable pulleys 6 through movable pulley axle 4, movable pulley bearing 5, and axle head baffle 7 that movable pulley axle 4 both ends set up will move pulley axle 4 and connecting plate 3 location. The movable pulley 6 and the movable pulley bearing 5 can rotate on the movable pulley shaft 4 to realize the lifting or the descending of the platform.
The utility model discloses a "U" open-ended shaft hole 8 on connecting plate 3, its upper end is semi-circular, and the lower extreme opening is equipped with trapezoidal reinforcing plate, is convenient for move loose pulley axle 4, movable pulley 6, moves loose pulley bearing 5's integral erection and demolishs. The movable pulley hoisting frame always bears the dead weight of the downward ship bearing platform 1 and the dead weight of a ship in the use process, and does not have upward stress. When the movable pulley hanger and the ship bearing platform 1 are fixed on the elevation of the terrace through the locking device, the shaft end baffle 7 is removed, the movable pulley block, the shaft and the bearing are assembled into an integral part, the installation and the removal are convenient, the conventional round shaft hole is avoided, and the shaft needs to be inserted and pulled out on site. The site is in the working condition of a water area, and the installation and the removal work are difficult to carry out under the construction condition. By adopting the open type hanger structure, the movable pulley block component can be integrally installed or disassembled, so that the shaft, the bearing, the pulley and other parts of the movable pulley block can conveniently enter a workshop for repair and maintenance.
The above is only to explain the utility model further, and not to limit the utility model, and all the equivalent implementations of the utility model should be included in the scope of the claims of the utility model.
