Description
Technical Field
The utility model belongs to the technical field of suspension bridge girder steel construction, a system that after the suspension bridge girder segment was transported to the hoisting position with fortune roof beam ship is related to, unload the roof beam segment from the ship and swing to the bridge on is related to.
Background
In the construction stage of installing the steel beams of the suspension bridge, beam transportation ships are generally adopted to transport the beam sections to a designated area in a water area with navigation conditions, and then the beam sections are hoisted to the beam transportation trestle from the ships. At present, a method for hoisting a beam section in a suspension bridge water area by unloading ships includes that a cable crane is adopted to hoist the beam section, as shown in fig. 1, the cable crane 16 firstly hoists a beam section 14 on a beam carrier 13 to a certain height, and then is matched with a horizontal traction device on a beam carrier trestle 15 to swing and move a steel beam onto the trestle, but the cable crane 16 is suspension bridge steel beam hoisting construction equipment, and the cable crane is moved for unloading ships, so that the hoisting construction time of a mid-span beam section is occupied, and the main construction period is influenced; another method is that a large floating crane 17 is directly adopted to lift the beam section 14 on the beam-transporting ship 13 to the shore as shown in fig. 2, although the hoisting of the midspan beam section is not affected, the use cost of the large floating crane is very high, and the construction cost is increased.
Disclosure of Invention
The utility model aims at guaranteeing suspension bridge waters beam section and unloading ship and lifting, swing when going ashore construction safety, do not occupy beam section hoist and mount construction main time limit for a project to make full use of original machinery, equipment carry out the structure of waters beam section system of unloading ship, and then reduce construction cost.
The technical scheme of the utility model as follows:
the utility model provides a suspension bridge waters beam segment ship unloading lifts by crane and swings system that moves which characterized in that: the temporary locking clamp is fixed on a main cable of the suspension bridge and is over against the lifting position of a lower beam section, the upper end of the temporary sling is fixed with the temporary locking clamp, the lower end of the temporary sling is connected with a fixed pulley of the pulley block, a movable pulley of the pulley block is connected with the lifting tool, the winch is arranged at an anchor of the suspension bridge, and the steering wheel is positioned below the temporary locking clamp and is fixed on a catwalk of the suspension bridge; and a traction rope of the winch crosses over the top of the cable tower of the suspension bridge through a cable saddle of the suspension bridge along the top surface of the catwalk, then bypasses the steering wheel and is connected with a pulley rope of the pulley block.
The utility model has the advantages that: reduced the equipment that suspension bridge waters beam section unloaded the ship and lifted the construction and dropped into, make full use of original machinery, equipment carry out waters beam section construction of unloading the ship the utility model discloses an in a concrete embodiment, used 30T hoist engine, leading wheel are former suspension bridge catwalk and erect stage and main cable and erect the used equipment of stage construction, interim hoist cable and interim cable clamp are the interim permanent hoist cable of suspension bridge and the permanent cable clamp of moving on temporarily, do not increase construction equipment cost, newly drop into the equipment and only be 200T tackle blocks, the cost is lower. The utility model discloses can with the parallel construction of suspension bridge girder segment hoist and mount, when carrying out suspension bridge waters girder segment and unloading ship and lift by crane, swing, not influence girder segment hoist and mount construction main time limit for a project to the construction equipment cost that has significantly reduced.

Detailed Description
As shown in fig. 3, fig. 4, and fig. 5, the utility model discloses a temporary clip 1, temporary sling 2, assembly pulley 3, hoist 4, and hoist engine 5 and directive wheel 6, temporary clip 1 is fixed on suspension bridge main cable 7 and is just to the lower beam section hoisting position, temporary sling 2 upper end is fixed with temporary clip 1, the lower extreme is connected the fixed pulley 31 of assembly pulley 3, the movable pulley 32 of assembly pulley is connected the hoist 4, hoist engine 5 is set up at suspension bridge anchorage 8, directive wheel 6 is located temporary clip 1 below and fixes on suspension bridge catwalk 9; the traction rope 10 of the winch 5 passes through a suspension bridge cable saddle 11 to cross the top of the suspension bridge cable tower 12 along the top surface of the catwalk 9, then bypasses the steering wheel 6 and is connected with the pulley rope 33 of the pulley block 3.
As a specific embodiment of the utility model, the winch can adopt a 30T winch used in construction of suspension bridge catwalk and main cable erection stage; in addition, when the traction rope of the winch crosses the tower top, a guide wheel needs to be arranged on the tower top, and the steering wheel or the guide wheel is also an existing field device. The temporary locking clamp and the temporary sling can temporarily use the locking clamp and the sling which are installed on the main cable, and the sling can also adopt the existing steel beam sling on the construction site.
The utility model discloses only the assembly pulley is newly-increased equipment, can adopt the 200T assembly pulley. The top of a fixed pulley 31 of the pulley block is provided with an upper ear plate, and the upper ear plate is connected with an anchor head at the lower end of the temporary sling 2 through a pin shaft; the bottom of the movable pulley 32 of the pulley block is provided with a lower ear plate, and the lower ear plate is connected with a suspender of the hanger 4 by a pin shaft.
After the lifting appliance 4 is connected with a beam section 14 on a beam transporting ship 13, a winch 5 is started to drive a pulley block 3 to lift the beam section 14 to a certain height through a traction rope 10, then the beam section is swung to a trestle through a horizontal traction device arranged on a beam transporting trestle 15, and the beam section is transported away through a beam transporting vehicle. The swinging process is the same as the swinging mode of the lifting beam section of the existing cable crane. The utility model discloses when unloading a ship, the cable carries the loop wheel machine and can normally carry out midspan girder steel hoist and mount construction.
