Abstract
The present invention relates to the improvement of a mechanical type asynchronous palate plate grab bucket, which belongs to bulk handling equipment. The grab bucket uses a hydraulic balance device for controlling the upper ends of each palate plate to move up and down or rotate in a guiding plate slot, which enables a palate plate having large resistance to transfer resistance through an oil pipe of a balancer, and thus, other palate plates can also bear larger resistance. Thus, the palate plates lie in different positions in the guiding slot so as to enable each palate plate to be asynchronously controlled to clamp materials of irregular shapes without leakage. The grab bucket has the advantages of simple structure, easy fabrication, convenient maintenance and equipment investment saving, and the work efficiency of the grab bucket can be nearly 3 times higher than that of a synchronous grab bucket.
Description
The present invention relates to the improvement of harbour, mine with the asynchronous machinery grab bucket of many palate plates, especially a kind of hydraulic balance asynchronous jaw plate grab bucket, it belongs to the mechanical equipment technical field of loading and unloading bulk goods.
Since this century, the development of bulk handling equipment is very fast.The asynchronous grab bucket of a kind of mechanical type palate plate is arranged.This grab bucket is on palate plate upper end and central sill closed wire rope pulley group to be housed, and utilizes numerous pulleys and the coiling cable wire on it that all palate plates are connected to each other and is in the same place.When asynchronous phenomenon appears in palate plate motion each other, the high and low position difference of each palate plate pulley in guide groove, thereby can make the material in the grab bucket be subjected to all the other palate plate compactings.Yet this pulley block system structure is huge, and pulley is too much, and cable wire kinks serious wear, and the resistance transmission loss of each palate plate is more, thereby the cables break phenomenon often occurs.Each palate plate its hinge joint that is in operation is often instead not motionless, and it is stressed excessive and cause palate plate not disconnected, damages grab bucket.This grab bucket is set prevents the central sill bevelled pilot bar of grabbing bucket, also often because the collision in the loading and unloading operation, impact and crooked or fracture.
Purpose of the present invention is exactly the defective that will overcome above-mentioned asynchronous grab bucket; simplify the grab bucket structure; reduce the pulley number; reduce the cable wire consumption, reduce the cable wire wearing and tearing, change the resistance transfer mode of palate plate when closure; it is stressed suitably to reach each palate plate; minimizing palate plate joint is anti-other, protects palate plate and joint thereof, and minimizing is leaked so that the equal energy of the material in the assurance grab bucket is clamped.Cost-cutting is wanted in the improvement of this grab bucket, improves work efficiency, prolongs the grab bucket life-span.
Task of the present invention is that following technical scheme realizes: developed a kind of hydraulic balance asynchronous jaw plate grab bucket.This grab bucket keeps deck beam, the central sill of the asynchronous grab bucket of former mechanical type palate plate, strut, palate plate, guide plate, facilities such as guide groove and bearing pin.Its concrete structure is: be fixed be hinged with on the deck beam of holding rope plurality of rows be listed in this beam surrounding edge along on orderly strut upper end.The end of this bar is hinged on its cooresponding palate plate lateral head and turns the place.All palate plates upper end also is hinged on around the central sill in an orderly manner, and can be in corresponding to the guide groove of a pair of guide plate of this palate plate upper and lower moving.The central sill of this grab bucket also is the closed rope by control palate plate closure, pass deck beam and introduce in the fixed pulley on the central sill, and with the deck beam relative motion, thereby realize grasping the purpose of material.Hydraulic balance asynchronous jaw plate grab bucket of the present invention, main improvement resistance transfer mode on the asynchronous balance play of palate plate: transmit resistance by the hydro-cushion device and realize each palate plate stress balance, it is asynchronous to move.The concrete structure that wherein said palate plate upper end is hinged on the central sill is: by can be at the slide block axle sleeve of upper and lower slip between a pair of guide plate plate with the bearing pin that is contained on this palate plate upper end, and be placed in the guide groove.Be hinged on all palate plates upper end the slide block axle sleeve bottom surface, lower end and hydro-cushion device each cooresponding piston boit mutually umbilical point contact.Palate plate both can rotate around bearing pin and slide block axle sleeve like this, again can be with the upper and lower slip of slide block axle sleeve in the rail between the guide plate plate.Driving these power that are hinged on the upper and lower slip of slide block axle sleeve of all palate plates upper end is hydro-cushion devices.Here it is under each bottom surface, palate plate institute pivotally attached slide block axle sleeve lower end, and the umbilical point contact has each cooresponding piston boit.Each piston boit is fused by the connected vessels type hydro-cushion device that cooresponding cover pillar oil cylinder is connected dress.Hydro-cushion device of the present invention, it is installed in the central sill bottom that all palate plates upper end is compiled.The cover pillar oil cylinder identical with all palate plates by number is fixed on lower end between corresponding guide plate plate.The bottom of all oil cylinders has bottom tube to be interconnected, and constitutes connected vessels type hydro-cushion device.
When the different bulk materials of palate plate clamping geomery, stressed big palate plate passes through its slide block axle sleeve to the lower compression piston boit, like this with the piston boit of hydraulic oil pressure under other stressed less palate plate, this piston boit is risen, thereby, connecting rod mechanism continues closing motion owing to making this stressed less palate plate, also bear bigger power until this palate plate, finally reach each palate plate stress balance, and realize that grab bucket motion between palate plate in closing course is asynchronous.Each palate plate of this realization upper end different balancing device in high and low position in guide groove is not pulley block system but hydro-cushion device.These two kinds of devices obviously have been hydro-cushion device simple possible.
The guide groove that this hydraulic balance asynchronous jaw plate grab bucket is set, but the upper and lower mobile distance of supply and marketing axle should be slightly larger than the palate plate blade tip by the vertical lift height that is flared in the closing course in its groove.Correspondingly the range of piston boit should equal the vertical lift height of palate plate blade tip.
The present invention reaches each palate plate stress balance owing to adopted the hydro-cushion device to transmit the palate plate resistance that is obstructed, and realizes that each palate plate motion is asynchronous.It is stressed even so both can to have reached each palate plate, and minimizing palate plate joint is anti-other, avoids stressed excessive relevant joint to suffer damage, and all energy is clamped can to make the material that enters in the grab bucket again, has reduced leakage.Because the hydro-cushion device is installed in the central sill bottom, increases central sill stability, has saved pilot bar mechanism, plays the effect of protection palate plate equally.The work efficiency of this grab bucket can improve.
