Description

Novel drawing shovel excavator

Technical field

The utility model relates to dragline technical field, in particular to a kind of novel drawing shovel excavator.

Background technique

Dragline: " retreat downwards, self weight cut soil ", shoveling radius and digging depth are larger, can excavate shutdown face with Under one to second level soil, when work, scraper bowl is thrown out using inertia force, digs distant.But it is flexibly accurate not as good as other, it is right There is very high requirement in the manipulation ability and operating experience of driver, generally requiring could be promoted by abrupt slope in certain height Not so scraper bowl will appear tipping bucket phenomenon.

Utility model content

The utility model provides a kind of novel drawing shovel excavator, can solve problem pointed in background technique.

A kind of novel drawing shovel excavator, including track rail assembly, chassis, upper mounting plate, swing mechanism, shovel mechanism and boom Mechanism is equipped with swing mechanism between upper mounting plate and chassis, upper mounting plate can be rotated around chassis, the upper mounting plate installation traction elevator With promotion elevator, the suspension arm mechanism is fixed on the top of upper mounting plate, and the shovel mechanism hangs over boom machine by ropes It on structure, and is controlled by the drag rope that traction elevator reaches shovel mechanism, the shovel mechanism includes bucket body, the shovel Struggle against ontology top setting movable pulley, penetrates the first rope on the movable pulley, the both ends of first rope are separately fixed at On the central point of bucket body rear and front end, link is fixed on the movable pulley, penetrates the second rope on the link, described The both ends of two ropes are symmetrically fixed on the left and right sides of bucket body rear end, and third rope, the third are fixed on the link The other end of rope is connected with drag rope, and the 4th rope is fixed in the left and right sides of the bucket body front end respectively, and described The other end of four ropes is connected with drag rope.

Preferably, pass through traction four-way connector, the traction between the drag rope and third rope and the 4th rope Four-way connector major joint is fixedly connected with drag rope, and excess-three connector is fixed with third rope and the 4th rope respectively to be connected It connects.

The utility model provides a kind of novel drawing shovel excavator, and by the improvement to shovel mechanism, scraper bowl is not needed Specific position and special angle can complete the promotion of scraper bowl, facilitate operation, reduce operation level and operation to driver The requirement of experience also improves working efficiency, and furthermore the utility model only changes the structure of shovel mechanism, in use, only needing Shovel mechanism is replaced, no replacement is required or other components are transformed, and also reduces acquisition cost, novel drawing shovel excavator, shovel Bucket ontology fills soil, and for ropes under the action of pulley, fulcrum Forward, drag rope keeps certain pulling force, bucket body Center of gravity is to the rear, and bucket body soil-unloading port tilts upwards, and scraper bowl is enable to lift easily in any position of work-yard, solves The troublesome operation of original equipment lift bucket, unclamps drag rope when unloading soil, causes to unload scholar mouthful weight imbalance, and soil-unloading port tilts down, Under the action of pulley, fulcrum moves back lift bucket rope, smoothly unloads soil.

Specific embodiment

With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this The protection scope of utility model is not limited by the specific implementation.

If Fig. 1-2 shows, a kind of novel drawing shovel excavator provided by the embodiment of the utility model, including track rail assembly 1, bottom Disk 2, upper mounting plate 3, swing mechanism 4, shovel mechanism and suspension arm mechanism 6, are equipped with swing mechanism 4 between upper mounting plate 3 and chassis 2, Upper mounting plate 3 can be rotated around chassis 2, and the installation of the upper mounting plate 3 traction elevator 7 and promotion elevator 8, the suspension arm mechanism 6 are fixed on The top of upper mounting plate 3, the shovel mechanism are hung on suspension arm mechanism 6 by ropes 9, and it is fixed that the top of suspension arm mechanism 6 is equipped with Pulley, ropes 9 are wound on fixed pulley, and are controlled by the drag rope 10 that traction elevator 7 reaches shovel mechanism, the shovel The mechanism that struggles against includes bucket body 5, and movable pulley 12 is arranged above the bucket body 5, penetrates the first rope on the movable pulley 12 Rope 11, the both ends of first rope 11 are separately fixed on the central point on 5 rear and front end top of bucket body, the movable pulley Link 13 is fixed on 12, the link 13 is fixedly connected with the end of ropes 9, penetrates the second rope on the link 13 14, the both ends of second rope 14 are symmetrically fixed on a left side for 5 rear end of bucket body (side far from traction elevator 7 is rear end) Third rope 15 is fixed on the link 13 in right two sides, and the other end and 10 end of drag rope of the third rope 15 are fixed The 4th rope is fixed in the left and right sides of connection, 5 front end of bucket body (side close to traction elevator 7 is rear end) respectively 16, the other end of two the 4th ropes 16 is fixedly connected with drag rope 10, and above-mentioned rope passes through hitch or rope sling and scraper bowl sheet Body 5 is fixed, and the bucket body 5 is equipped with trunnion or fixation hole.

As shown in figure 4, passing through traction four-way connector between the drag rope 10 and third rope 15 and the 4th rope 16 17,17 major joint of traction four-way connector is fixedly connected with drag rope 10, excess-three connector respectively with third rope 15 It is fixedly connected with the 4th rope 16.

Working principle of the utility model is: such as Fig. 1, Fig. 3, Fig. 4, it is shown, in use, first being adjusted according to operation earth material situation Each rope length is saved, the center of gravity after making bucket body 5 fill earth material is located at the first half of bucket body 5, when work, scraper bowl 5 turns of ontology full earth materials, it is continual and steady adjustable inside to the offer of drag rope 10 one by driver's control traction elevator 7 Pulling force makes it overcome bucket body 5 since center of gravity is forward, and front end can topple downwards, in the inside pulling force that drag rope 10 provides Under effect, bucket body 5 is made to be in horizontal stable state, while operating control traction elevator 7 and promoting elevator 8 and turn to By scraper bowl mobile discharge area, at this moment, operation traction elevator 7 discharges drag rope 10, at this moment acts on flat on bucket body 5 Weighing apparatus power is broken, and earth material is gradually poured out, and repeats aforesaid operations, completes excacation.

Disclosed above is only several specific embodiments of the utility model, and still, the utility model embodiment is not office It is limited to this, the changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
