Ship hydraulic remote control grab bucket of the present invention, comprise bucket body and entablatrance, described bucket body two ends connect two struts respectively, the other end of strut is connected with entablatrance, the upper surface of described entablatrance is connected with compensation frame by steel rope, be provided with moved cross beam and lower moved cross beam immediately below entablatrance, described upper moved cross beam is connected with entablatrance by hydraulic actuating cylinder.
Preferably, entablatrance is welded with pulley erecting frame, Pressure Block, described pulley is connected with entablatrance by bearing pin, and top is provided with wear-resistant sleeve.
Preferably, upper moved cross beam is fixedly linked by the piston rod of bolt and hydraulic actuating cylinder, upper moved cross beam is also welded with pulley erecting frame, rope compensation frame erecting frame, up and down locating dowel pin, upper moved cross beam is connected by axle with between assembly pulley, affixed with the compensation frame on upper moved cross beam after the assembly pulley in steel wire penetrating entablatrance.
Preferably, lower moved cross beam is box type construction, is connected as a single entity with control box, and fuel tank, hydraulic pressure and electrical apparatus control system are equipped with in inside, and lower moved cross beam is all connected by axle with hydraulic actuating cylinder and bucket body synchronizer gear.
Structure of the present invention and simple to operate, reliable working performance, is not easy to break down, and easy care has good market outlook.
Accompanying drawing explanation
Fig. 1 is ship hydraulic remote control grab bucket schematic diagram.
Reference numeral, 1-compensates frame, 2-entablatrance, 3-hydraulic actuating cylinder, moved cross beam under 4-, 5-steel rope, 6-strut, the upper moved cross beam of 7-, 8-bucket body.
Detailed description of the invention
Ship hydraulic remote control is grabbed bucket, comprise bucket body 8, entablatrance 2 and controller, it is characterized in that described bucket body 8 two ends connect two struts 6 respectively, the other end of strut 6 is connected with entablatrance 2, the upper surface of described entablatrance 2 is connected with compensation frame 1 by steel rope 5, be provided with moved cross beam 7 and lower moved cross beam 4 immediately below entablatrance 2, described upper moved cross beam 7 is connected with entablatrance 2 by hydraulic actuating cylinder 3.Entablatrance 2 is welded with pulley erecting frame, Pressure Block, described pulley is connected with entablatrance by bearing pin, and top is provided with wear-resistant sleeve.Upper moved cross beam 7 is fixedly linked by the piston rod of bolt and hydraulic actuating cylinder 3, upper moved cross beam 7 is also welded with pulley erecting frame, rope compensation frame 1 erecting frame, up and down locating dowel pin, upper moved cross beam 7 is connected by axle with between assembly pulley, and steel rope 5 is through affixed with the compensation frame 1 on upper moved cross beam 7 after the assembly pulley in entablatrance 2.Lower moved cross beam 4 is box type construction, and be connected as a single entity with control box, fuel tank, hydraulic pressure and controller are equipped with in inside, and lower moved cross beam 4 is all connected by axle with hydraulic actuating cylinder and bucket body 8 synchronizer gear.
The action such as opening and closing, locking of this grab bucket adopts unpowered design.Grab bucket, fall the weight-lifting equipment carried by boats and ships and complete, folding and lock to have been come by hydraulic efficiency pressure system, it is primarily of compositions such as hydraulic actuating cylinder 3, piston, control cock, fuel tank and oil pipes.Principle, the working process of grab bucket can be divided into following several stages: empty bucket moves aloft, left and right bucket body respectively opens 95 °, piston is extracted out from hydraulic actuating cylinder 3 completely, upper piston area space only has very little dash clearance, lower space is full of hydraulic oil, now, fluid control valve is in right position, and the hydraulic oil of lower space is blocked.
Grab bucket falls on material, and the grab bucket of opening is placed on goods under the drive of ship hoisting equipment, loosens hoist cable, and piston falls by the Action of Gravity Field of upper moved cross beam, and piston moves down.Now, fluid control valve right position conducting.Before piston moves down and contacts with hollow plunger, an oil part for hydraulic actuating cylinder 3 lower space enters the upper space of hydraulic actuating cylinder 3 by interior oilhole and check valve, and unnecessary part oil is by pipeline oil sump tank; When piston move down contact with hollow plunger time, the hydraulic oil in cylinder lower space flows into upper space mainly through check valve, by oil outlet and pipeline oil sump tank.When piston be displaced downwardly to seal outer oilhole time, piston stop move down.The hydraulic oil on hydraulic actuating cylinder top is blocked.
Mention lifting rope rope, pick up freight lifting power and be delivered to upper moved cross beam 7 and piston through cable wire, because the hydraulic oil on hydraulic actuating cylinder 3 top is in locking state, oil can not flow out and produce oil pressure, make that hydraulic actuating cylinder is subject to power upwards with lower moved cross beam 4 and with piston upward movement, bucket body 8 tightens up and picks up goods and promotes with rope.Then by lifting appliance by goods movement to the position of specifying, prepare unloading.
Grab bucket is opened, is unloaded, and when goods is moved to assigned address, makes fluid control valve left position conducting by command and control system, and upper moved cross beam 7 is fixing under the traction of cable wire.Grab bucket is under the Action of Gravity Field of lower moved cross beam 4, bucket body 8 and goods, lower moved cross beam 4 and hydraulic actuating cylinder 3 move down, before hollow plunger and piston depart from, the hydraulic oil of hydraulic actuating cylinder 3 upper space flows back to fuel tank by interior oilhole, hollow plunger, oil pipe and control cock, simultaneously fuel tank by oil pipe to the repairing of hydraulic actuating cylinder 3 lower space.The aperture of control cock is very little, and the flow velocity of hydraulic oil is less, and speed of initially opening of grabbing bucket is slow.Prevent goods from initially unloading and let slip fast and larger impact is produced to goods reception facilities; When hydraulic actuating cylinder 3 move down depart from hollow plunger time, hydraulic actuating cylinder 3 upper space hydraulic oil by the direct person who lives in exile's lower space of interior oilhole, grab bucket open fast.Unloading of goods later stage can be made like this to put speed, grab bucket can be made simultaneously to produce larger force of inertia, the goods sticking to bucket body surface is come off.
Emergency operation, when emergency condition such as command and control system break down, can pull manual unloading mechanism, forces to make control cock left position conducting, unloads, tries to avert accidents.
