Description
Technical field
The utility model relates to a kind of excavator, is specifically related to the dipper on a kind of excavator.
Background technology
Increasing along with the national basis building project, particularly some subterranean tunnel engineerings and zanjon operation, requirement to excavator is tending towards specialized, require excavator the special-purpose equipment of suitable operating mode will be arranged down, to reduce power consumption, to enhance productivity at special operating mode, special manipulating object.Described equipment is by swing arm, dipper, scraper bowl (or quartering hammer etc.), and the composition such as boom cylinder, bucket arm cylinder, bucket cylinder that drives each component movement, is hinged between swing arm, dipper and the scraper bowl.
In tunneling operation, when big cubic metre of earth of deep foundation ditch operation of needs, often take several excavator relay operations at present, the dipper that at this moment extends just can play a role; And for example need then often to realize under the situation of big digging force, big capacity scraper bowl by shortening bucket arm length in mine, quarry etc.; As seen, at different digging forces, need to adopt the dipper of respective length.Yet in the prior art, it is good that the length of dipper is all just determined before excavator dispatches from the factory, be changeless, this just requires the user to purchase the excavator of different configurations, satisfy the needs of actual job, increased construction cost accordingly, if ignore this point, will at utmost damage digging machine, descend to application life.Therefore, existing dipper structural limitations the scope of application of digging machine, can not adapt to the numerous and diverse operating environment of excavator.
Summary of the invention
The utility model purpose provides a kind of excavator boom, uses the dipper of this structure, can adapt to the several work environment, has expanded the scope of application of excavator, reduces construction cost, prolongs the application life of digging machine.
For achieving the above object, the technical solution adopted in the utility model is: a kind of excavator boom, comprise a body, the body two ends are respectively equipped with the hinge hole that is connected with swing arm, dipper, also be provided with the fixing hole that bucket arm cylinder and bucket cylinder are installed respectively, described body is made up of matrix and mobile for dividing body structure, described swing arm hinge hole and bucket arm cylinder fixing hole are arranged on the described matrix, and described scraper bowl hinge hole and bucket cylinder fixed hole position are in described mobile; Described matrix top is provided with chute, the bottom surface of described mobile cooperates with this chute, formation is slidingly connected, described mobile is provided with the connection pin-and-hole of at least two horizontal level unanimities, be provided with the adjusting play between the adjacent connection pin-and-hole, described matrix is provided with the connection lug, has through hole on this lug, and described mobile fixedlys connected with the lug on the described matrix through bearing pin and securing member.
In the technique scheme, described body is made of mobile and matrix, chute through the matrix top between described mobile and the matrix is slidingly connected, described mobile is provided with at least 2 and connects pin-and-hole, and there is the adjusting play between adjacent connection pin-and-hole, in use, needs according to digging force and excavation depth, select the corresponding pin-and-hole that connects to be connected with lug on the matrix, when needs lengthening body length, utilize the weight of body self, mobile slides onto the connection pin-and-hole place of nearly fuselage along the chute at matrix top, pass lug on the matrix with bearing pin, again through securing member (as bolt etc.) stationary positioned; Otherwise; when needing to shorten, the pulling force that utilizes bucket arm cylinder to shrink will draw in the mobile; move to the connection pin-and-hole place of nearly scraper bowl (or other equipment such as quartering hammer etc.) side; with bearing pin and securing member location, so just can satisfy the needs of different digging operations, the applicable multiple occasion of main frame again; reduce construction cost; and adjust body length according to excavating needs, can effectively protect the application life of digging machine, avoid the overburden operation.
In the technique scheme, be provided with pressing plate along the dual-side of described chute, this pressing plate one end and described matrix are fixed, and are provided with the gap between the other end and chute bottom surface, constitute stopper slot, and the bottom surface dual-side of described mobile stretches out, and is inserted in the described stopper slot.The stopper slot that pressing plate and chute bottom surface constitute defines mobile's bottom slippage in chute, avoids mobile that the phenomenon of chute takes place to break away from when slippage.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, because adopting, dipper body of the present utility model divides body structure, constitute by matrix and mobile, the bottom surface of mobile cooperates with the chute at matrix top, formation is slidingly connected, be provided with at least 2 in the mobile and connect pin-and-hole, needs according to digging operation, mobile mobile also selects suitable connection pin-and-hole and matrix to fix, thereby realizes the conversion of dipper body total length, to adapt to different digging forces, the needs of excavation depth, a main frame can replace multiple host, reduced construction cost, the length of simultaneously in good time change dipper body is kept away an overburden operation, the protection main frame increases the service life;
2, the utility model utilizes the gravity of dipper body self and the pulling force of bucket arm cylinder to finish mobile's moving up and down in the matrix chute, need not body is removed, and is simple to operate, saves engineering time and labour cost.
