Description

A kind of swing arm of excavator

Technical field

The utility model belongs to excavator parts technical field, more particularly to a kind of swing arm of excavator.

Background technology

Excavator is also known as excavating machinery, also known as excavator, is to be excavated to be higher or lower than the material for holding machine side with scraper bowl, and fill Enter haulage vehicle or unload to the earthmoving machinery of rickyard.From the point of view of the development of engineering machinery in recent years, the development of excavator is relative Comparatively fast, excavator has become one of most important engineering machinery in engineering construction.Swing arm, dipper refer to a kind of work of excavator Make device, be generally also large arm, forearm, main function is for dominating the action such as the excavation of bucket, entrucking.It is connected with frame Arm is longer, so being commonly called as being referred to as swing arm for large arm, its term；The arm being connected with bucket is smaller, so being commonly called as claiming for forearm, term Make dipper, so it is big forearm to be commonly called as them.The shape of backacter swing arm, all it is to have certain curved position in general, Preferably it can so be excavated by force for the soil below shutdown face, forward shovel is but typically straight, so Preferably it can be excavated by force for soil more than shutdown face；Existing excavator swing arm is more to be fixed each part by welding Connection, connection is not very firm, when carrying out excacation, because swing arm is by larger power, so swing arm and its junction meeting There is slight crack, cause potential safety hazard, it is therefore desirable to which a kind of new technical scheme solves this technical problem.

Utility model content

The purpose of this utility model is to provide a kind of swing arm of excavator, to solve what is be previously mentioned in above-mentioned background technology Problem.

To achieve the above object, the utility model provides following technical scheme：A kind of swing arm of excavator, including the first case Body and the second casing, one end of the first casing are fixed with front fork, and one end of the second casing is fixed with the second bearing, and described It is fixedly connected between one casing and the second casing by the first bearing, the both ends of first bearing are provided with flange, and described first Casing is equipped with the fixed card slot being engaged with flange, first casing and the second box house with the other end of the second casing Provided with floor.

As a kind of optimal technical scheme of the present utility model, the floor is made up of some groups of floor blocks, each rib It is fixedly connected between plate by connecting pole.

As a kind of optimal technical scheme of the present utility model, the floor block includes outer framework and support bar, the branch Strut is fixedly installed on inside outer framework, and the corner of the outer framework is provided with connecting hole.

As a kind of optimal technical scheme of the present utility model, the outer framework is in triangular shape, and the support bar is fixed on Between hypotenuse and summit, the connecting hole is arranged at three corners of outer framework.

As a kind of optimal technical scheme of the present utility model, the base of the outer framework is horizontal, and its corner is also in flat Face, it is fixed on the inwall of the first casing and the second casing.

As a kind of optimal technical scheme of the present utility model, at least provided with four groups of floor blocks on the floor.

The beneficial effects of the utility model：The utility model by will be first passed through between excavator swing arm each several part flange with Groove connects, and by welding, further improves the fastness between swing arm each several part parts, and be provided with rib inside swing arm Plate, the rigidity of swing arm can further improve by the structure and shape of floor, when excacation is carried out, prevents slight crack, Cause potential safety hazard；The utility model is simple in construction, easy to use, has both improved the rigidity of swing arm itself, while also further So that the connection between swing arm each several part is more firm, ensureing its safe handling, the utility model simple operation is practical, It is easy to promote the use of, the service life of excavator swing arm can be greatly prolonged.

Embodiment

Lower combination accompanying drawing illustrates to preferred embodiment of the present utility model, it will be appreciated that described herein preferred Embodiment is merely to illustrate and explained the utility model, is not used to limit the utility model.

Fig. 1 to Fig. 5 is referred to, the utility model provides following examples, a kind of swing arm of excavator, including the first casing 1 and second casing 2, one end of the first casing 1 be fixed with front fork 5, one end of the second casing 2 is fixed with the second bearing 6, institute To state and be fixedly connected between the first casing 1 and the second casing 2 by the first bearing 3, the both ends of first bearing 3 are provided with flange 7, First casing 1 is equipped with the fixed card slot 8 being engaged with flange 7, first casing 1 with the other end of the second casing 2 Floor 9 is provided with the inside of the second casing 2.

Wherein floor 9 is made up of at least four groups of floor blocks 91, is fixed and connected by connecting pole 92 between each floor block 91 Connect；Floor 9 supports swing arm inside swing arm, anti-stopper arms because stress is excessive and caused by slight crack, and some groups of floor blocks 91 can Stress preferably is shared, makes it more firm；Floor block 91 includes outer framework 911 and support bar 912, and the support bar 912 is solid Surely it is arranged on inside outer framework 911, the corner of the outer framework 911 is provided with connecting hole 913；Outer framework 911 supports swing arm, And support bar 912 is responsible for further reinforcing outer framework 911 and it is further stablized, significant effect, and outer framework 911 is in triangle Shape, support bar 912 are fixed between hypotenuse and summit, and connecting hole 913 is arranged at three turnings of outer framework 911 Place；This structure make it that floor block 91 is more firm, plays more preferable reinforcement effect, while pass through connection by connecting pole 92 Hole 913 is fixedly connected, convenient use, stabilization and reinforcement；The base of outer framework 911 is horizontal simultaneously, and its corner is also in plane, fixed On the inwall of the first casing 1 and the second casing 2；It so may be such that floor block 91 more facilitates, is stably fixed to swing arm Inside, easy to use, support effect is good.
