Abstract
The present invention provides an anti-rolling device of container spreader, including hoist rope crossed wrap system composed of four groups reels, pulley block etc and a top track device mounted on the wheelbarrow, also including a wheelbarrow mounted on the structure frame main beam rail and a container spreader connected with the wheelbarrow. The four groups reels are lifting reels, mounted on the top of the bottom beam of the structure frame, connected with motor, speed reducer, coupling etc, a driving system forms a lifting and wheelbarrow operation. The driving type of the wheelbarrow is pull behind, horizontal moving along the steel rope on the structure frame main beam. The top track device of the wheelbarrow is mainly composed of an electrohydraulic thruster, a link mechanism, a top track block, a supporter etc, playing an important role in braking, preventing fore-and-aft movement along the rolling of the container spreader. The anti-rolling device has a simple structure, convenient controlling, effectively prevents rolling of the container spreader, and increasing the efficiency of cargo-handling and the comfort of operation because of the rolling of the cab caused by relaxation of the steel rope when the container spreader descends to place the container.
Description
Technical field
The present invention relates to container handling crane, particularly a kind of container sling anti-sway device.
Background technology
Container handling crane is in operation process, because the starting and the braking of dolly and cart, suspender and the freight container that is lifted by crane thereof produce and wave.The running velocity of dolly or cart is high more, and the amplitude of waving is big more, and the time of the pendulum that disappears is long more, has a strong impact on handling efficiency.Because the waving of suspender makes the dolly that is attached thereto also along with moving forward and backward, be installed in driver's cab below the dolly and also can produce and rock, the driver has human discomfort in the driver's cab the inside.In addition, in the process that the handling freight container descends, freight container under being suspended on container spreader land or land at other above freight container the time, the steel rope that links to each other with container spreader is a relaxed state, at this moment be suspended on driver's cab below the dolly because inertia moves forward and backward with dolly, also can make the driver produce human discomfort.Therefore, on container handling crane, need the installing container sling anti-sway device.
Summary of the invention
The invention provides a kind of container sling anti-sway device, be particularly suitable for a kind of container sling anti-sway device of light tyre formula gantry container crane.
Technical scheme of the present invention is, a kind of container sling anti-sway device, it comprises that the hoist rope that is made of four groups of reels, assembly pulley etc. intersects winding system and be installed in head track device on the dolly, also comprises dolly that is installed on the structure-steel framing girder track and the container spreader that is connected with dolly by steel rope.Described four groups of reels are hoisting drum, are installed in above the bottom girder of structure-steel framing, link to each other with motor, retarder, coupler etc., constitute the drive system that hoists with trolley travelling.The drive form of described dolly is towed, makes parallel motion with steel rope on the structure-steel framing girder.The head track device of described dolly mainly is made of electro hydraulicthruster, connecting rod mechanism, head track piece, support etc., can play brake action to dolly, prevents that dolly from moving forward and backward.
The invention has the beneficial effects as follows that hoist rope intersection winding system is simple and practical, actv. prevents waving of container spreader; Dolly head track apparatus structure is simple, control is convenient, can prevent that container spreader from descending when putting freight container because waving of the lax driver's cab that causes of steel rope increased the traveling comfort of handling efficiency and operation widely.

The specific embodiment
Among Fig. 1, four groups of reels (1) are arranged in above the both sides bottom girder of structure-steel framing, every side is furnished with two groups of reels, two groups of reels with the left side are example, after steel rope I lays out from reel a1, walk around the pulley b1 of structure-steel framing assembly pulley (2) vertically upward, transfer the pulley c11 of horizontal direction in going into dolly assembly pulley (3) to, intersect downwards and link to each other with the pulley d32 of suspender assembly pulley (6), then upwards around the pulley c12 that goes into dolly assembly pulley (3), downwards around the pulley d12 that goes into suspender assembly pulley (6), upwards, be fixed on the dolly after coming out again around pulley c5 to dolly assembly pulley (3).Two groups of reels on right side twine with the same manner, have promptly constituted to hoist and trolley travelling steel rope intersection winding system.
Like this, by top special steel rope intersection canoe, actv. has prevented waving of suspender.In order to reduce the impact that is suspended on the driver's cab below the dolly and to wave, on dolly, set up dolly head track device, prevent that suspender from descending when putting freight container, drive waving of the driver's cab that is suspended on below the dolly because steel rope is lax.
Among Fig. 2, dolly head track device is mainly by electro hydraulicthruster (11), connecting rod mechanism (12), head track piece (14), support formations such as (13).Electro hydraulicthruster (11) links to each other with connecting rod mechanism (12), connecting rod mechanism is provided with slide block below (12), square head track piece (14) links to each other with the slide block of connecting rod mechanism (12), support (13) is fixed on the front end of car frame (10), support (13) is provided with the flute profile slideway, and the slide block of connecting rod mechanism (12) can slide up and down along the flute profile slideway of support (13).Be in " opening " state by electric system control electro hydraulicthruster (11), the slide bar of electro hydraulicthruster (11) promotes connecting rod mechanism (12), connecting rod mechanism (12) withstands on above the orbit plane (9) head track piece (14), head track piece (14) bottom surface that contacts with orbit plane (9) is provided with groove, increase friction force, prevent effectively that by the friction force effect dolly from moving forward and backward; Adopt between the slide block of head track piece (14) and connecting rod mechanism (12) to be threaded, can adjust the gap between head track piece (14) and the orbit plane (9).When control electro hydraulicthruster (11) when being in " pass " state, electro hydraulicthruster (11) automatically resets by spring, makes head track piece (14) deorbit plane (9).Adjust the gap between head track piece (14) and the track for convenience, being connected between head track piece (14) and the support (13) made the pattern that is threaded.
Among Fig. 3, the action of dolly head track device is determined by the state of " jack-up " or " whereabouts " of container spreader rotary-locking device push rod.Push rod is shown that by jack-up container spreader falls above the freight container that is hung, this moment container spreader and the freight container that hung should be in land or other container state.Otherwise push rod falls to showing that container spreader has been sling freight container or is no container state under the suspender.If program judges that the state of push rod is " jack-up ", then open the electro hydraulicthruster (11) of dolly head track device, make head track piece (14) withstand on the orbital plane, prevent that dolly from causing moving forward and backward of dolly because of steel rope is lax.Open when container spreader revolves lock, when suspender climbed away freight container, the push rod state became " whereabouts ", and electro hydraulicthruster (11) is closed and automatically reset by action of the spring, head track piece (14) deorbit this moment, and dolly can move freely.
