Description

Hang at the floating type seat end

The utility model relates to the floating type seat of lifting and hangs at the end.

The deck crane that the state-run oasis machine plant of Chinese vessel main office is made, its purpose is to carry out lifting operation on the ship.Its structure is single, double boom crane, can carry out operation at sea.Weak point is that it can not the seat end, and ship can not leave water surface work, wind-proof and wave-proof not, also incompatible in the coastal waters or other shoal water zone carry out lifting operation, and involve great expense, operating costs is also very high.

The purpose of this utility model be to avoid above-mentioned weak point of the prior art and at the bottom of a kind of flexible displacement waterborne, positioning seat be provided, both can in water, can leave the water surface, resist stormy waves, the floating type seat end that can extensively carry out lifting operation in offshore banks, rivers and lakes hangs.

The purpose of this utility model can reach by following measure: the chassis that hang at the floating type seat end is a pipe-support type II font structure, fixedly floating drum, guide pipe, lifting floating drum are coupled, and the pulley steel cable system of two-way winch, guide frame, the pole-climbing of corner formula and control corner formula pole-climbing rotation and lifting buoy lifting is installed on top.

The purpose of this utility model can also reach by following measure: fixedly floating drum is airtight hollow tube-shape structure, its central mounting guide pipe, and there are link and lower sheave in its both sides, and guide pipe stretches out fixedly that floating drum partly has radial hole.The lifting floating drum is the tubular structure of airtight hollow, and its base pipe places guide pipe, and the operation of lifting therein.Lifting floating drum top connects base pipe, and top block is arranged at its top, middlely partly passes radial hole on this hole and the guide pipe with radial hole with bearing pin, with fixing lifting floating drum.The pole-climbing of corner formula is installed in front end center, top, pipe support chassis, and its top is the criss-cross shelf structure of band pulley, and middle and lower part and a Y shape supporting leg link, and the lower end is hinged.Y shape supporting leg with in guide frame up and down the leg of operation be connected, leg is installed on the seesaw frame in the guide frame.Guide frame is installed on the pipe support chassis, and seesaw frame and fixed pulley group wherein are installed, and the upper and lower running block that is equipped with of seesaw frame is with the seesaw frame up-and-down movement.The chain wheel rope cable system that the pole-climbing of control corner formula is rotated comprises guide frame and the running block that is installed on it thereof, fixed pulley group, Y shape supporting leg, leg, two-way winch and steel cable system.The pulley steel cable system of control lifting floating drum up-and-down movement comprises top block, lower sheave, track adjusting wheel, suspension ring, the fixedly link and the steel cable system of steel cable.The pole-climbing corner is finished by the two-way winch and the pulley steel cable system that are installed on the pipe support chassis.When two-way winch was just changeing, the pulling steel cable by guide frame top fixed pulley group, drove seesaw frame and rises, under the promotion of leg and Y shape supporting leg, and pole-climbing rotations that promptly turn forward, on the contrary during two-way winch counter-rotating, seesaw frame is descending, the pole-climbing withdrawal.The operation crane winch hangs up on the suspension ring with suspension hook and to carry, and under the strong pressure of steel cable, at the bottom of the lifting floating drum seat, passes hole on guide pipe and the lifting floating drum base pipe with bearing pin, is fixed.Take away bearing pin, under buoyancy, the lifting floating drum resets, and fixes with bearing pin again.

Fig. 2 is the birds-eye view of front view of the present utility model;

Fig. 3 is the anterior lifting floating drum pulley system figure of front view of the present utility model;

Fig. 4 is the rear portion lifting floating drum pulley system figure of the utility model front view;

Fig. 5 is the guide frame front view of the utility model front view;

Fig. 6 is the guide frame lateral plan of the utility model front view;

Fig. 7 is another structure cut-away view of the lifting floating drum of the utility model front view.

The utility model is described in further detail below in conjunction with accompanying drawing:

As Fig. 1, Fig. 2, chassis (1) makes II font pipe support structure by steel pipe, four fixedly floating drum (2) make airtight hollow tube-shape shape structure by sheet metal, be connected as a single entity with flange for four jiaos with the pipe support chassis.Fixedly the floating drum central vertical is installed guide pipe (10), and it exceeds fixedly that floating drum partly has radial hole.Fixedly floating drum (2) is divided into lifting floating drum (3), and it makes airtight hollow tube-shape structure with steel plate, and base pipe (31) is arranged at top.Base pipe passes guide pipe (10), and there is top block (13) on its top, and radial hole is arranged on the base pipe.Tubular corner formula pole-climbing (4) is erect in the center, front portion on pipe support chassis (1), and its top is the criss-cross frame (6) of band pulley, and the lower end is a strand connection.

As Fig. 3, Fig. 4, there are link (12) and lower sheave (14) in guide pipe (10) both sides, steel cable (16) is fixed on the link (12), the other end passes top block (13) and lower sheave (14) and track adjusting wheel (17), cause the front jockey wheel (19) of corner formula pole-climbing (4) both sides, be connected on the suspension ring (20), operation crane winch (9), hang up on suspension ring (15) and (20) with suspension hook (5) and to carry, lifting floating drum (3) the seat end under the suppressing of steel cable (16,18), pass hole on guide pipe and the lifting floating drum base pipe (31) with bearing pin (11), the lifting floating drum is fixed.

As Fig. 5, Fig. 6, Y shape supporting leg (29) is connected in the corner formula pole-climbing (4), its other end with penetrate the leg (28) that guide frame (8) goes up in the square hole (23) of seesaw frame (24) and link to each other.Seesaw frame has running block (22) up and down, and guide frame has fixed pulley group (21,25) up and down, and winch steel cable (27) is walked around winch (26), is fixed after passing running block (22) and fixed pulley group (21,25) again.Winch (26) is when just changeing, and the pulling seesaw frame is up, and Y shape supporting leg is up thereupon, and the pole-climbing of corner formula is rotated forward, otherwise, the winch counter-rotating, seesaw frame is descending, and the pole-climbing of corner formula resets.

As Fig. 7, be the another kind of version of lifting floating drum (2), when it rose under the buoyancy of water effect, the lifting floating drum was hidden fixedly in the cavity of floating drum (30).

The utility model has the following advantages compared with prior art:

1, can in water, float, with machinery or artificial pulling displacement;

2, at the bottom of the lifting floating drum seat, can make the chassis exceed the water surface, operation under stability.

3, wind-proof and wave-proof is impacted, and normal lifts under stormy waves impacts is equivalent to land crane normal operation.

4, complete machine cost cost is low, has only 1/10 of equal load-bearing capacity crane, the also corresponding reduction of executive cost.

5, convenient transportation, when transporting at a distance, but the roping of split dismounting machinery.

6, safety performance is good, and the operation displacement steadily.

7, comformability is strong, and at various construction dykes and dams waterborne, displacement flexibly under positioning operation, the quick condition, construction operation is very convenient, quick.
