Abstract
The utility model discloses a hydraulic crawler excavator operation device, which is mainly improved on the basis of the prior excavator complete appliance, wherein, a bucket rod oil cylinder is arranged at the lower side of a moveable arm and a bucket rod. The utility model comprises the moveable arm, the bucket rod and the bucket rod oil cylinder. The hydraulic crawler excavator operation device is characterized in that the hinge point of the moveable arm and the bucket rod oil cylinder is positioned at the lower side of the moveable arm; the hinge point of the bucket rod and the bucket rod oil cylinder is positioned at the lower side of the bucket rod; one end of the bucket rod oil cylinder is hinged with the moveable arm, and the other end is hinged with the bucket rod.
Description
Technical field
The utility model is applied to hydraulic digger operating device, particularly relates to the hydraulic digger operating device of the arrangement of bucket arm cylinder in the hydraulic digger operating device.
Background technology
At present, in mine and tunneling operation, artificial entrucking efficient is low, and cost height, and operating condition is abominable is dangerous high, is difficult to recruit enough workmans, and most of ore deposits contractor that advocates peace wishes to find a kind of suitable machinery to replace.Adopting hydraulic crawler excavator to replace workman's entrucking is a kind of good selection, but the bucket arm cylinder of hydraulic digger operating device all is the top that is arranged in swing arm both at home and abroad, this cover equipment is less compliant in operation in narrow and small mine in space and the tunnel, and bucket arm cylinder is scratched easily in the operation in mine and tunnel, injured by a crashing object by stone easily, the piston rod of oil cylinder is also made dirty easily.
Summary of the invention
The purpose of this utility model is to provide can operation in narrow and small mine in space and tunnel; and protect bucket arm cylinder well; simultaneously can reduce the complete machine operation height; but still can satisfy simple in structure that loading and unloading require; make easily; easy to install, the hydraulic digger operating device that safety factor is high.
Technical solution of the present utility model is such: a kind of bucket arm cylinder is arranged in the hydraulic digger operating device of swing arm below, comprises swing arm, dipper, bucket arm cylinder.It is characterized in that: bucket arm cylinder is installed in the below of swing arm and dipper, and bucket arm cylinder one end and swing arm are hinged, and the other end and dipper are hinged.Pin joint is below swing arm between swing arm and the bucket arm cylinder, and pin joint is below the dipper between dipper and the bucket arm cylinder.
The utility model has the advantages that, bucket arm cylinder is arranged in the below of swing arm in the hydraulic digger operating device, in the narrow and small mine and tunnel in space, can reduce the complete machine operation height, but still can satisfy the loading and unloading requirement, and bucket arm cylinder can be hidden in the below of swing arm dipper well, and the excavator driver is equally free and relaxed with operation in the open when operation, and need not worry that bucket arm cylinder can be damaged, entrucking efficient height.Have simple in structure, easily manufactured, with low cost, dependable performance, operating efficiency height in narrow and small mine in space and tunnel.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 is for having the excacation device schematic diagram of commercially available hydraulic crawler excavator now.
Fig. 2 is an excacation schematic representation of apparatus of the present utility model.
Fig. 3 is the utility model result of use figure in the tunnel.
Fig. 4 is the utility model result of use figure in mine.
Among Fig. 1～Fig. 2: swing arm (1), bucket arm cylinder (2), dipper (3), pin joint (4), pin joint (5).
The specific embodiment
Most preferred embodiment of the present utility model is such, with reference to Fig. 1～Fig. 2, on the basis of original excavator complete machine, bucket arm cylinder (2) is arranged in the below of swing arm below and dipper, change the arrangement of the installation position of articulating point of bucket arm cylinder (2), the hinge of described bucket arm cylinder (2) one ends is arranged in the bottom of swing arm (1), and the hinge of the other end is arranged in the bottom of dipper (3).Described bucket arm cylinder (2) mounting means is the same with the mounting means of general excavator bucket rod oil cylinder, is furnished with pin joint (4) under swing arm (1) push rod, and it is hinged to be connected with pin joint (4) between bucket arm cylinder (2) one ends and the swing arm (1).It is hinged to be connected with pin joint (5) between side and the bucket arm cylinder (2) under dipper (3).Promote the flexible motion work up and down of pulling dipper (3) by bucket arm cylinder (2), the connection relation between swing arm (1) and the dipper (3) is constant.But reach by transformation of the present utility model and to improve the excavator service behaviour, make excavator have more advantages such as simple in structure, carrying height, installation, convenient disassembly be quick.Referring to Fig. 3～Fig. 4, bucket arm cylinder is arranged in the excavator of swing arm below, in narrow and small mine in space and tunneling operation, can use freely.
The utility model is on the basis of original excavator complete machine, only need to change swing arm, dipper, boom cylinder, bucket arm cylinder, again each hinge on reasonable Arrangement swing arm and the dipper, and miscellaneous part need not be changed greatly basically, still can satisfy the loading and unloading requirement when reducing the complete machine operation height.So just can make a excavator that is useful in very much operation in narrow and small mine in space and the tunnel, have good market prospects, widen the range of application of excavator.
Claims (2)
1, a kind of equipment of hydraulic crawler excavator, comprise swing arm, dipper and bucket arm cylinder, it is characterized in that: bucket arm cylinder (2) is installed in the below of swing arm (1) and dipper (3), and bucket arm cylinder (2) one ends and swing arm (1) are hinged, and the other end and dipper (3) are hinged.
2, according to the equipment of the described hydraulic crawler excavator of claim 1, it is characterized in that: pin joint (4) is swing arm (1) below between swing arm (1) and bucket arm cylinder (2), dipper (3) below of pin joint (5) between dipper (3) and bucket arm cylinder (2).
