Description
Technical field
The utility model relates to a kind of for ship unloaders grab bucket maintenance and steel wire rope of grab bucket replacing inspection platform.
Background technology
Development along with present harbor service, the raising of the degree of specialization of the handling facilities of bulk cargo terminals, technical requirements to the former grab bucket that belongs to general work rigging is also more and more higher, the particularly grab bucket of large-tonnage ship unloaders institutes adapted, and its structure plays conclusive effect to the raising of the efficiency of loading and unloading.Adopt the 1200/h bridge-type grab ship unloader as Raw Material Wharf, the grab bucket that is equipped with mutually with it is 34T two Hubei Province plate four rope ore grab buckets (YRKD34 type).Ship unloaders come into operation in process, and the maintenance of grab bucket and replacing are routine works.The whole deadweight of its grab bucket is 14t approximately, and height is up to 5.5 meters and because the main carriage motion of ship unloaders is rectilinear motion, grab bucket can only realize the inclination of a direction.Therefore, when the grab bucket damage needed repairing and changes steel wire rope of grab bucket, the ship unloaders grab bucket was to fall.At present, in maintenance and when changing the ship unloaders grab bucket normally the maintainer climb and carry out operation in grab bucket.There is following shortcoming in this mode: 1, space for maintenance is not enough, and the grab bucket headroom is too small and have long-pending oil to exist, and personnel are dangerous in upper maintenance; 2, grab bucket excessive height, climbing is inconvenient; What 3, split hoists, opens and closes wire rope without fixed connection point, has unsafe factor; 4, the maintainer carries a large amount of maintenance tools, the inconvenience maintenance.When overhauling as stated above, difficulty is large, and wastes time and energy, and easily does over again, and repair quality can not be guaranteed.Therefore be necessary this situation is improved.Through retrieval, Chinese patent 200420070197.8 discloses " automatic overhauling platform of ladle turner ", but this inspection platform roller driving device moves forward and backward inspection platform, but this type of drive, level requirements for ground is higher, can't satisfy the movement of uneven ground and stablize.
Summary of the invention
The purpose of this utility model is to provide integral type ship unloaders grab bucket repairing platform device.Mainly solve existing inspection platform and can't satisfy the movement of uneven ground and stable technical problem.
technical solutions of the utility model are: integral type ship unloaders grab bucket repairing platform device, comprise the platform bottom surface, column, inspection platform, staircase and driving mechanism, column is arranged on the platform bottom surface, inspection platform is fixed on column, staircase one termination platform bottom surface, another termination inspection platform of staircase, driving mechanism is installed in bottom, platform bottom surface, it is characterized in that: described driving mechanism is by travel driving unit, front-wheel drive system, transition wheel and rear end road wheel, travel driving unit is fixed on the platform bottom surface, front-wheel drive system is by the front end road wheel, guide rod, spring and crawler belt consist of, the front end road wheel is fixed on an end of bottom, platform bottom surface, a plurality of guide rods are circumferentially uniform along the front end road wheel, on each guide rod, spring is housed, form spring roller, spring roller and transition wheel axis pass through crawler haulage, transition wheel circumferentially and travel driving unit pass through belt transmission, the rear end road wheel is fixed on bottom, the platform bottom surface other end.
According to grab bucket open, the closure state height is different, maintenance is made of upper and lower two-layer platform, realizes that grab bucket maintenance and steel wire rope of grab bucket change.The tool box is placed on the platform bottom surface, determines the installation site in tool box according to the position of centre of gravity of single unit system, makes center of gravity more stable.Ship unloaders hoist, open and close wire rope when changing steel wire rope of grab bucket has fixing suspension centre on this platform, hoists, opens and closes the pulling force effect of wire rope for inspection platform is overcome, so this platform relative weight is heavier.
The beneficial effects of the utility model are: 1. this device is provided with two-layer inspection platform, can satisfy the grab bucket maintenance of differing heights.2. in this platform start-up course, due to volume and weight larger, be unfavorable for that the normal mobile and cart rail level of inspection platform passes through.So designed a kind of new drive unit, this device power is belt wheel transmission, executive component be the rolling wheel for caterpillar spring from pressure device, drive transition wheel by motor-driven and rotate to realize slow down, transition wheel is connected by belt with belt pulley, realizes rotation.When inspection platform integral body was passed through ship unloaders cart orbit plane, because this track belongs to embedded, there was the hole groove on the surface.Inspection platform by the hole during groove rolling wheel for caterpillar spring realize its function from pressure device, the stressed extruding of the cylindrical spring that contact with ground is shunk automatically, makes the contact area increase on crawler belt and ground, the expansion friction factor.Thereby make automatic damping effect when realizing the crawler belt auto-tensioning and crossing track.The spring assembly summit through ground after, utilize the elastic force of spring self to make its recovery.The crawler belt inboard is according to the number of the telescopic spring bar groove that evenly distributes, since realize that rolling wheel for caterpillar telescopic spring bar when rotating is fixed in groove, makes crawler belt not produce skidding.3. a tool box is installed in the platform bottom, the instrument unification of maintenance repair grab bucket is put the Quick overhaul of convenient grab bucket.Reduce the repair time.Mainly meet following index: (1) is safe and reliable, and is simple in structure.(2) can reach the purpose of maintenance grab bucket and replacing steel wire rope of grab bucket.(3) laborsaving, can reduce operating personnel's labour intensity.(4) save time, shorten repair schedule.(5) manufacturing cost is low.
