Abstract
The invention relates to a floating crane. The floating crane comprises a pedestal, which is fixed on a floating boat, a rotary table is arranged on the pedestal, the upper part of the rotary table is provided with a machine room, the machine room comprises an operation chamber, the operation chamber comprises a lifting mechanism and a power control part; a column is welded on the rotary table, a luffing mechanism is arranged on the column, a balancing system is arranged on the top part of the column, a lifting arm is hinged on the rotary table, the upper part of the lifting arm is hinged to the balancing system through a connection rod, one end of a steel wire rope is connected to the lifting mechanism, the steel wire rope goes through the balancing system and is connected to a grab in the head part of the lifting arm. The floating crane has the advantages of compact and reasonable structure and convenient operation. The arm support adopts a truss structure, thus the wind resistant force is small during the operation process; moreover the luffing mechanism adopts a gear and rack mechanism, so that the luffing motion is faster, and the work efficiency is higher.
Description
Technical field
The present invention relates to weight-lifting equipment technical field, especially a kind of floating crane.
Background technology
Floating crane is also referred to as crane ship or crane barge.Non-self-propelling crane ship is used in inland harbour, conventionally on square boat deck, multi-form hoisting crane is set, floating crane can carry out the loading and unloading operation between bank and ship, ship and ship, and it takes up an area few from heavy and light, work efficiency is high, job stabilization is good, goes slick, and is the desirable handling equipment in lake, inland river.Be specially adapted to harbour dredging and Wharf Engineering construction operation, as uses such as grapple dredger, floating sand unloading machine, floating coal unloaders.
The changing-breadth system of floating crane of the prior art adopts rope luffing more, troublesome poeration, and functional reliability is poor, affects work efficiency.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of floating crane rational in infrastructure, thereby adopts the luffing mechanism of rack-and-gear.
The technical solution adopted in the present invention is as follows:
A floating crane, comprises the base being fixed on pontoon, on described base, turntable is installed, and the top of described turntable is provided with machine room, in described machine room, comprises operator's compartment, comprises lifting mechanism and power-control section in described operator's compartment; On described turntable, be welded with column, on described column, luffing mechanism is installed, the top that is positioned at column is provided with balanced system, on described turntable, be hinged with crane arm, described crane arm top is hinged by pipe link and balanced system, steel rope one end lifting mechanism connects, and steel wire penetrating balanced system to crane arm head connects grab bucket.
Further improvement as technique scheme:
The structure of described luffing mechanism is: comprise the gear being fixed on column, with the tooth bar of gear engagement, one end of described tooth bar is fixed on column, and the other end of described tooth bar is articulated with on crane arm.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, easy and simple to handle, jib adopts truss structure, and the resistance that is subject to wind during operation is little, and luffing mechanism adopts pinion and rack, makes luffing action faster, and operating efficiency is higher.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the floating crane of the present embodiment, comprises the base 8 being fixed on pontoon, and turntable 7 is installed on base 8, and the top of turntable 7 is provided with machine room 2, in machine room 2, comprises operator's compartment, comprises lifting mechanism and power-control section in operator's compartment; On turntable 7, be welded with column 3, luffing mechanism 4 is installed on column 3, the top that is positioned at column 3 is provided with balanced system 1, on turntable 7, be hinged with crane arm 9, crane arm 9 tops are hinged by pipe link 5 and balanced system 1, steel rope 6 one end lifting mechanisms connect, and steel rope 6 connects grab bucket 10 through balanced system 1 to crane arm 9 heads.
The structure of luffing mechanism 4 is: comprise the gear 11 being fixed on column 3, with the tooth bar 12 of gear 11 engagements, one end of tooth bar 12 is fixed on column 3, and the other end of tooth bar 12 is articulated with on crane arm 9.
In actual use procedure, the luffing of controlling crane arm 9 by pinion and rack moves.Flexible movements are reliable.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
