Abstract
A novel operating apparatus for loading machine belongs to the technological field of the engineering machinery. The main technical features are that: when the dynamic-arm hydraulic cylinder is raised, the dynamic arm can rotate an angle of delta alpha counterclockwise around the point B. The pressure oil in the the no-rod cavity of the bucket cylinder which is used for translating and guiding is discharged into the rod cavity of the hydraulic cylinder of the bucket; the pressure oil in the rod cavity of the hydraulic cylinder of the bucket is discharged into the no-rod cavity of the bucket cylinder which is used for translating and guiding; the piston rod of the hydraulic cylinder of the rotary bucket extends outward; the bucket relatively rotates clockwise around the point D with an angle of delta theta The arrangement position and size of the two hydraulic cylinders should be reasonably determined to make the angle delta alpha to be about equal to the angle delta theta; the dynamic arm makes the bucket keep the translational motion while being lifted upward and downward; meanwhile, the hydraulic cylinder of the rotary bucket can singly work when the dynamic arm rotates to any position, to realize the bucket collection and the material unloading.
Description
The present invention relates to the equipment of loader in the construction machinery and equipment commonly used.
Working device of loader is to finish loading and unloading operation and with the multi-bar linkage of oil cylinder, is one of critical component of forming loader; The height of its design level directly influences the quality of equipment performance, and then influences the work efficiency and the economy index of complete machine.The most frequently used working device of loader mainly is made up of scraper bowl, swing arm, connecting rod, rocking arm, bucket cylinder, boom cylinder, front vehicle frame and hydraulic efficiency pressure system etc. in the engineering at present; For translation, unloading property, the not many requirements such as interference capability, dynamic property and digging force, mechanism efficiency etc. of satisfying loader, need they organically are hinged together, various connecting rod mechanisms (as four, five, six, eight connecting rod linkages) have been formed, wherein the six bar mechanism articulated manner is as follows: swing arm lower link point and scraper bowl are hinged, last hinge and front vehicle frame bearing hinge; Bucket cylinder one end and front vehicle frame are hinged, and the other end and upper rocker arm are hinged; Boom cylinder one end and front vehicle frame are hinged, and the other end and swing arm are hinged; Connecting rod one end and rocking arm are hinged, and the other end and scraper bowl are hinged; Rocking arm is hinged on the swing arm.This shows, these equipment complex structures, difficult design even adopt the computer optimization method of designing, does not fundamentally solve discharging and translation, dynamic property and the scraper bowl contradiction between the property set level automatically yet.And these equipments can make the hinge-point change in location along with the wearing and tearing of hinge-point copper sheathing, influence the translation, discharging of loader and performance such as interference capability not.Therefore, must often change the copper sheathing of each hinge-point, have a strong impact on the work efficiency of loader.
By the Internet inquiry, various although the equipment of at present domestic and international loader has, its principle of work still belongs to the above-mentioned type, does not also have the patent of the equipment of loader.
The objective of the invention is: adopt the full hydraulic equipment, simplify the structure and the method for designing of equipment; Even and realize also guaranteeing the serviceability of loader under the situation of each hinged severe wear; Solve the problem that exists in the background technology effectively.
The technical solution used in the present invention is: connecting rod in the equipment and rocking arm are removed, replace with a scraper bowl translational guidance oil cylinder, realize the action of equipment by fluid control.Its hinge method is as follows: on swing arm 3, be connected with scraper bowl 1, bucket cylinder 2, boom cylinder 4, scraper bowl translational guidance oil cylinder 5 and rotary ink tank; It is characterized in that swing arm 3 lower link points and scraper bowl 1 are hinged, last hinge and front vehicle frame bearing hinge; Rotary ink tank 2 one ends and scraper bowl 1 are hinged, and the other end and swing arm 3 are hinged; Boom cylinder 4 one ends and front vehicle frame are hinged, and the other end and swing arm 3 are hinged; Scraper bowl translational guidance oil cylinder 5 one ends and front vehicle frame are hinged, and the other end and swing arm 3 are hinged; The rod chamber of bucket cylinder 2 is communicated with oil pipe 6 with the rod chamber of scraper bowl translational guidance oil cylinder 5, and the rodless cavity of bucket cylinder 2 is communicated with oil pipe 6 with the rodless cavity of scraper bowl translational guidance oil cylinder 5.
The present invention compares with background technology, and the useful effect that is had is:
1. the problem that adopts all-hydraulic control can overcome hinge-point copper sheathing wearing and tearing effectively and cause serviceabilitys such as loader translation, discharging, dynamic property to reduce, thus the work efficiency of loader improved;
2. adopt scraper bowl translational guidance oil cylinder, but design processes simplified, and the designing requirement that is content with very little;
3. simple in structure, compactness, cost is low;
4. be easy to realize the mechanical-electrical-hydraulic integration of working device of loader with all-hydraulic control, for the intellectuality of loader from now on creates conditions.
Because of a little, it can be promoted the use of in similar engineerings such as loader factory machinery producer.
The invention will be further described below in conjunction with accompanying drawing.
Accompanying drawing; Structural representation of the present invention.
Fig. 1 is the structure principle chart of equipment of the present invention, equipment by scraper bowl 1, bucket cylinder 2, swing arm 3, boom cylinder 4, scraper bowl translational guidance oil cylinder 5 and in succession the oil pipe 6 etc. of bucket cylinder and scraper bowl translational guidance oil cylinder form.Between the rod chamber and rod chamber of bucket cylinder 2 and scraper bowl translational guidance oil cylinder 4, by the oil circuit intercommunication, and be in the normal open quick condition between rodless cavity and the rodless cavity.Because scraper bowl guiding translation oil cylinder 5 and boom cylinder 4 all are hinged on back front vehicle frame (drawing in the end) and the swing arm 3, so during swing arm 3 liftings, scraper bowl translational guidance oil cylinder 5 idle rods 3 do to involve swing, the corresponding mandatory fore and aft motion of piston rod idle rod 3 swings of scraper bowl translational guidance oil cylinder 5.When the piston rod of scraper bowl translational guidance oil cylinder 5 shrank, its rodless cavity was to bucket cylinder 2 rodless cavity oil extractions, and rod chamber then replenishes fluid by the bucket cylinder rod chamber, and bucket cylinder 2 piston rods stretch out, and vice versa.Like this, when swing arm 3 liftings, bucket cylinder 2 piston rods promote scraper bowl 1 corresponding rotation simultaneously, and scraper bowl 1 remains horizontality, prevents that material from scattering.When swing arm 3 descends, make scraper bowl 1 keep horizontality equally.Be in the optional position fixedly the time at swing arm 3, scraper bowl translational guidance oil cylinder 5 coupler locks, and bucket cylinder 2 still can work independently, receipts bucket and discharging when realizing that scraper bowl is any.When boom cylinder 4 lifts swing arm 3, make swing arm 3 when the B point rotates counterclockwise Δ α angle, swing arm 3 is rotating simultaneously, BC limit compression with scraper bowl 1 translational guidance oil cylinder 5, make the oil of this oil cylinder rodless cavity be extruded into the rodless cavity of bucket cylinder 2, with the EF limit elongation of bucket cylinder, bucket cylinder 2 drives scraper bowl 1 and clockwise rotates Δ θ angle around the relative swing arm 3 of D point.If can make Δ α=Δ θ, scraper bowl 1 just can be realized the rigid body translation in these two positions so, make Δ α=Δ θ, as long as reasonably determine the installation site and the size of bucket cylinder and scraper bowl translational guidance oil cylinder.
