Description

Waterpower inserting plate balancing hoisting machine

One, technical field

The utility model relates to loop wheel machine, particularly a kind of waterpower inserting plate balancing hoisting machine.

Two, background technology

Finish the hydraulic sheeting construction task and must rely on lifting appliance, particularly will enter subaqueous work, land loop wheel machine advances not go, and crane barge waterborne because be subjected to stormy waves to influence unstable working condition, is influenced by draft also simultaneously again, and a lot of shallow waters along the coast can't enter.Moreover the One-Shift Costs height of crane barge has increased construction cost again.On the other hand, the existing single pole loop wheel machine safety and stability of going all out to be unfavorable for more greatly before when lifting operation, also suitable difficulty of the transfer of whole loop wheel machine and dismounting transportation after construction finishes.

Three, summary of the invention

The technical problems to be solved in the utility model is to overcome or the shortcoming avoiding existing in the above-mentioned prior art or not enough and a kind of waterpower inserting plate balancing hoisting machine is provided, finish plate construction operation waterborne and general lifting operation task, safety and stability problem when having solved lifting operation by two pairs of mutual balances of suspension rod, loop wheel machine and chassis rise in the air with latch by wire rope pulley group pressurization and are fixed on the influence of avoiding stormy waves when making the loop wheel machine lifting operation on four spud legs during work.In the work progress during shift position pressure-bearing buoyancy tank of four spud leg bottoms shrink and enter that whole waterpower inserting plate balancing hoisting machine becomes a binary pontoon in the chassis, before the construction, the bulk-breaking transportation, assembled on site, after the construction, the bulk-breaking dismounting, transportation, shift very convenient.

The utility model comprises connecting frame, binary buoyancy tank, lifting spud leg, rotating disk, winch, suspension rod and chain wheel rope cable system, it is characterized in that on the described binary buoyancy tank connecting frame being installed, this connecting frame both upper ends thereof is equipped with rotating disk, winch and suspension rod and rope pulley bracing frame are installed on the rotating disk, described binary buoyancy tank two ends are equipped with lifting spud leg and pressure-bearing buoyancy tank, described rotating disk winch and suspension rod are symmetric design, form the two-shipper balance crane.

The lower end of wherein said binary buoyancy tank is provided with circular depressed, and described pressure-bearing buoyancy tank can be hidden in wherein.Described suspension rod lower end is a compasses formula structure, flexibly connects with rotating disk and installs.Described connecting frame is vertical installation with the binary buoyancy tank.

According to above-mentioned principle, described rotating disk is installed on link span central authorities, and two suspension rods are installed on it, forms two bar balance cranes.

The utility model has following advantage or beneficial effect compared with prior art:

1, the loop wheel machine lift-off is fixed on four spud legs during construction operation, is equivalent to marine oil drilling platform, has solved crane barge waterborne and influenced by stormy waves to play pendulum the problem that influences construction.

2, two pairs of suspension rod balances are installed in when having solved lifting operation on the chassis folk prescription to stressed too big crank-sided problem.

3, two suspension rod cross-operation have improved work efficiency.

4, adopt wire rope pulley group pressurization lifting loop wheel machine to compare with the mode of traditional hydraulic lifting or rack-and-gear lifting to have processing and fabricating convenient, infusion of financial resources is few, and rising or falling speed is fast, the distinguishing feature that safety of operation is stable.

5, adopt the binary buoyancy tank as hull, it is little to have a wind-engaging wave resistance, and the property of floating on the water walking safety and stability is good.

6, bulk-breaking is prefabricated, bulk-breaking transports, field-installed version helps satisfying the need of work under the different situations.

Fig. 6 shrinks and to enter the loop wheel machine chassis and form a twin-hull pontoon and swim in constitution diagram on the water surface for the finish pressure-bearing buoyancy tank of four spud leg bottoms of work

Five, the specific embodiment:

Referring to Fig. 1～Fig. 6, a kind of waterpower inserting plate balancing hoisting machine, comprise connecting frame 3, binary buoyancy tank 1, lifting spud leg 2, rotating disk 4, winch 5, suspension rod 6 and chain wheel rope cable system, connecting frame 3 is installed on the binary buoyancy tank 1, this connecting frame both upper ends thereof is equipped with rotating disk 4, and winch 5 and suspension rod 6 and rope pulley bracing frame are installed on the rotating disk, and binary buoyancy tank 1 two ends are equipped with lifting spud leg 2 and pressure-bearing buoyancy tank 10, rotating disk 4 winches 5 and suspension rod 6 are symmetric design, form the two-shipper balance crane.

Wherein the lower end of binary buoyancy tank 1 is provided with circular depressed, and pressure-bearing buoyancy tank 10 can be hidden in wherein.Suspension rod 6 lower ends are compasses formula structure, flexibly connect with rotating disk 4 and install.Connecting frame 3 is vertical installation with binary buoyancy tank 1.

Rotating disk 4 is installed on connecting frame 3 central authorities, and two suspension rods 6 are installed on it, forms two bar balance cranes.
