Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, this mining scraping plate electric hydraulic excavating machine includes the large arm in excavator upper frame 4, the sub-arm 2 being connect with the large arm 4, rotary oil cylinder 3 built in sub-arm 2, the forearm 1 that the sub-arm 2 connects;Forearm 1 Connection bucket 12 is controlled by telescopic oil cylinder.Large arm 4 and sub-arm 2 and forearm 1 constitute three joint arms work structuring of the invention.
It further include being disposed through the intracavitary scraper plate conveyer belt 8 of chassis of dredging machine, 8 front end of scraper plate conveyer belt is equipped with shovel Bucket 14.
Further, it is connected between the large arm 4 and sub-arm 2 by telescopic oil cylinder.It realizes between sub-arm 2 and large arm 4 Flexible operation.
Further, rotary oil cylinder 3 built in the sub-arm 2.Rotary oil cylinder 3 can realize ± 90 degree of rotations, meet 360 degree of nothings Obstacle is broken to be excavated.
Further, it is connected between the sub-arm 2 and forearm 1 by telescopic oil cylinder.It realizes between forearm 1 and sub-arm 4 Flexible operation.
Further, the scraper plate conveyer belt 8 passes through the control driving of hydraulic motor 7.Scraper plate transport is realized by hydraulic motor 7 With 8 operating.
Further, the scraper bowl 14 is controlled by the bucket cylinder 13 being set on chassis of dredging machine.Pass through bucket cylinder 13 Realize the adjusting of 14 operation height of scraper bowl.
Further, 8 rear portion of scraper plate conveyer belt is controlled by scraper plate oil cylinder 9.Scraper plate transport is realized by scraper plate oil cylinder 9 Height adjustment with 8 rear portions.
Further, pass through the connection driving of revolving support 11 between excavation machine worktable and the chassis.Pass through revolving support 11 realize the operation of workbench 360 degree rotation.
This excavator in the case where clearing up scraper plate conveyer belt 8 when falling coal, three joint arms can be stretched to whereabouts, and (bucket 12 is not touched Ground), 90 ° of sub-arm oil cylinder of rotation (forearm 1, bucket 12 are rotated with rotary oil cylinder 3 built in sub-arm 2) shrinks stretching for forearm 1 Contracting oil cylinder finely tunes the telescopic oil cylinder of sub-arm 2 and large arm 4 that is, so that forearm 1 forms an angle with 2 shape of sub-arm, make forearm 1, Bucket 12 flushes ground handling, and joint component cooperates, and bucket 12, which is drawn, digs tunnel inner belt dropping coal.
Workbench and scraper conveyor belt 8 are mutually indepedent.Solve the space construction limitation of existing mining scraping plate digging machine, work Make platform can 360 ° rotation, excavation, planted agent, finishing and the cleaning of any direction.The intracavitary scraper plate conveyer belt in chassis operates normally, no Influence the rotation of upper stages.
This excavator is driven Variable plunger pump by fire-proof motor and provides hydraulic power source for complete machine;Hydraulic power source passes through oil circuit, more Road valve group and guide switch realize to scraper plate, large arm, sub-arm, forearm, bucket, scraper bowl, walking control.
When this excavator works, power is provided by mine electric system, rotary oil cylinder 3 built in sub-arm 2 makees ± 90 ° of rotations Turn, hydraulic motor 7 drives scraper plate conveyer belt 8 to operate, and scraper plate oil cylinder 9 can be with the height at 8 rear portion of telescopic adjustment scraper plate conveyer belt, row Forward-reverse can be realized by walking driving device 10, and revolving support 11 can drive 360 ° of upper stages rotations, and bucket cylinder 13 can be with The height of telescopic adjustment scraper bowl 14.
Roadway repair work is completed in three joint arms cooperation, and bucket 12 pulls over the material cleaned out to scraper bowl 14, bucket cylinder Scraper bowl 14 is lifted in 13 stretchings, and material is poured into chassis cavity of resorption inside strake conveyer belt 8 from scraper bowl reserved opening, passes through entire scraper plate Material is transported to transport vehicle railway carriage by conveyer belt 8.
In conclusion the present invention uses the structure type of three joint arms, can be adjusted according to tunnel size variation job state Working arm stretches amplitude, the facilities such as anchor cable, anchor pole, the back in tunnel is avoided collision, to make excavator in different height Spend flexible operation in section;The sub-arm added can realize ± 90 degree of rotations by rotary oil cylinder, and 360 degree of satisfaction is accessible broken Excavate, equipment can match bucket, quartering hammer, hydraulic shear and manipulator, realize high torque output, low energy consumption, low noise, Accurate control construction;Workbench is controlled by pivoting support, realization workbench 360 degree rotation, any direction excavation construction, even if Under the minimum radius of gyration, it also can get the excavation effect of large area, do not stay any construction dead angle;It is defeated with scraper plate by scraper bowl The structure type with cooperation is sent, realizes excavation, scraper integration, excavator bucket, scraper bowl and scraper plate conveyer belt can same lucks It goes and is independent of each other;Complete machine meets the requirement of the various actions such as excavation, side digging, broken rock, scraper, can complete a mao ditch, float coal The multinomial work such as cleaning, scarfing cinder, smooth tunnel;Overall performance is reliable, strong applicability, and the operation of mine excavator greatly improved Efficiency and operational security, significantly reduce labor intensity.
