Abstract
The utility model discloses a kind of excavator crane arm buffer units, including:The section of pedestal, the pedestal is " Π " shape, and the bottom surface at the pedestal both ends is equipped with through-hole；The buffer stopper being embedded in pedestal, the buffer stopper is rectangle, and pedestal is stretched out in the upper surface of the buffer stopper, and the both ends of the buffer stopper are equipped with through-hole, the through-hole is penetrated through with the through-hole on pedestal, and the through-hole on screw bolt passes buffer stopper, the through-hole rear thread on pedestal connect crane arm；It is fixedly connected on the plug on crane arm positioned at pedestal both ends, the plug is triangle.When operation, weedtree buffer stopper in the buffer unit of crane arm lower part can only be hit by shoveling the end crossbeam of bar, due to the flexibility effect of weedtree block, play good cushioning effect.The utility model is simple in structure, durable, and good buffer effect improves production efficiency, reduces production cost.
Description
Technical field
The utility model belongs to flight-line maintenance technical field more particularly to a kind of excavator crane arm buffer unit.
Background technology
Excavator is widely adopted in mining production operation, is particularly important to the maintenance and repairing of excavator, by
It can be impacted, be shaken in operation in excavator, especially shoveling the end crossbeam of bar can frequently hit in operation process
The lower part of weighing arm, this shock can damage excavator.Usually it is utilized in the side of the bottom placement rubber block of crane arm
Method slows down the shock to crane arm, but this rubber block service life is short, need to often replace, and certain shadow is caused to production
It rings, also increases the production cost of enterprise.
Utility model content
Above-mentioned in order to solve the problems, such as, the utility model proposes a kind of excavator crane arm buffer unit, the devices
Simple in structure, durable, good buffer effect improves production efficiency, reduces production cost.
To achieve the goals above, the utility model uses following scheme, and the device is evenly distributed to be threaded in lifting
The bottom of arm, described device include:
The section of pedestal, the pedestal is " Π " shape, and the bottom surface at the pedestal both ends is equipped with through-hole；
The buffer stopper being embedded in pedestal, the buffer stopper are rectangle, and pedestal, institute are stretched out in the upper surface of the buffer stopper
The both ends for stating buffer stopper are equipped with through-hole, which penetrates through with the through-hole on pedestal, through-hole, bottom on screw bolt passes buffer stopper
Through-hole rear thread on seat connects crane arm；
It is fixedly connected on the plug on crane arm positioned at pedestal both ends, the plug is triangle.
The pedestal is made of channel steel, and the buffer stopper is made of weedtree, and the plug is made of iron block.
The plug being fixedly connected on crane arm, is that plug is welded on crane arm.
The evenly distributed buffer unit for being threaded in crane arm bottom is four.
When operation, weedtree buffer stopper in the buffer unit of crane arm lower part can only be hit by shoveling the end crossbeam of bar, due to
The flexible effect of weedtree block, plays good cushioning effect.
The utility model is simple in structure, durable, and good buffer effect improves production efficiency, reduces production cost.
Description of the drawings
Fig. 1 is the schematic diagram that the utility model is connected on crane arm.
Fig. 2 is the elevational schematic view of Fig. 1.
Fig. 3 is the utility model main structure diagram.
Fig. 4 is the left view partial schematic sectional view of Fig. 3.
Fig. 5 is the utility model stopper structure schematic diagram.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can be more
Add and be clearly understood from, as shown in figure 1, figure 2, figure 3, figure 4 and figure 5, the utility model uses following scheme, the device evenly distributed
It is threaded in the bottom of crane arm 5, described device includes:
The section of pedestal 1, the pedestal 1 is " Π " shape, and the bottom surface at 1 both ends of the pedestal is equipped with through-hole；
The buffer stopper 2 being embedded in pedestal 1, the buffer stopper 2 are rectangle, and bottom is stretched out in the upper surface of the buffer stopper 2
The both ends of seat 1, the buffer stopper 2 are equipped with through-hole, which penetrates through with the through-hole on pedestal 1, and bolt 3 sequentially passes through buffer stopper 2
On through-hole, through-hole rear thread on pedestal (1) connect crane arm 5；
It is fixedly connected on the plug 4 on crane arm 5 positioned at 1 both ends of pedestal, the plug 4 is triangle.
The pedestal 1 is made of channel steel, and the buffer stopper 2 is made of weedtree, and the plug 4 is made of iron block.
The plug 4 being fixedly connected on crane arm 5, is that plug 4 is welded on crane arm 5.
The evenly distributed buffer unit for being threaded in 5 bottom of crane arm is four.
When operation, the end crossbeam 7 of shovel bar 6 can only hit the weedtree buffer stopper 2 in the buffer unit of 5 lower part of crane arm,
Due to the flexibility effect of weedtree block, good cushioning effect is played.
The utility model is simple in structure, durable, and good buffer effect improves production efficiency, reduces production cost.
