Technical field
The utility model is related to excavating machinery technical fields, and more particularly, to a kind of fixation kit, one kind is fixed with this
The counter weight of excavator of component and a kind of excavator with the fixation kit or the counter weight of excavator.
Background technology
Excavator is also known as excavating machinery, is that a kind of excavated with scraper bowl is higher or lower than the material for holding machine side, and material is filled
Enter haulage vehicle or unload to the earthmoving machinery of rickyard.The material that excavator excavates is mainly soil, coal, silt and passes through pre-
Soil and rock after pine.From the point of view of the development of engineering machinery in recent years, the development of excavator is relatively fast, excavator into
For one of most important engineering machinery in engineering construction.
Counter weight of excavator is that the important component designed is worked normally for excavator, and shell is generally by punching press moulding
Steel plate be welded, enclosure interior filling iron sand, shot, quartz, the substances such as cement, counter weight of excavator it is bulky,
Weight is larger and rotator inertia is big.Counter weight of excavator needs to be mounted on Platform of Excavators.In the prior art, counter weight of excavator
It is bolted with Platform of Excavators, and is divided into and being horizontally mounted and vertically-mounted two ways.It is horizontally mounted mode such as Fig. 1 institutes
Show, bolt 3 ' is threaded to fit by the screw rod of bolt 3 ' through stretching into the threaded hole on counter weight of excavator 2 ' after Platform of Excavators 1 '
After the torque of conjunction；Vertically-mounted mode is as shown in Fig. 2, the screw rod of bolt 3 ' stretches into excavator after passing through counter weight of excavator 2 '
In threaded hole on platform 1 ', after bolt 3 ' to be threaded to suitable torque.
However, the weight due to excavator in itself is larger and rotator inertia is larger, larger power can be applied to bolt, and
The position shape change dramatically that the screw rod of bolt has a common boundary with head, works one section at the phenomenon that generating stress concentration in excavator
After time, bolt is easily broken off, and there are larger security risks.
