Description
Technical field
The present invention relates to a kind of excavator components, more specifically to a kind of excavator boom.
Background technology
Excavator working environment is very severe, especially the excavator in mine work, often in the process of handling ore
It is middle to occur there is a phenomenon where ore hits dipper bottom.To protect dipper, mitigate impact of the ore for dipper, mine type excavates
Machine dipper bottom is generally all welded with impact protector structure.The structure type of existing dipper impact protector structure as shown in Figure 1,
Reinforcing plate is welded in dipper bottom and welds several reinforcing ribs in reinforcing plate, which arranges along bucket arm length.Reinforce
The welding manner of muscle is using intermittent weld along its length.
Above-mentioned dipper impact protector structure has the following problems：
1, it is weaker to absorb ore impact capacity.In above-mentioned dipper impact protector structure, reinforcing rib is entity, intensity compared with
Greatly.When ore impacts dipper, reinforcing rib transmits the impact energy of ore on dipper bottom plate along its length, ore impact
Whole energy still act on dipper bottom plate, cannot by impact energy to the both sides of bottom plate transmit so that be transmitted to dipper two
On side plate, easily causes the impact that dipper bottom is born and deform greatly very much, and then cause dipper bottom plate and dipper both sides plate-side plate welding
It cracks and fails in place.
2, the dipper impact protector rigidity of structure is excessive.In above-mentioned dipper impact protector structure, reinforcing rib is along bucket arm length side
To arrangement and quantity it is more, cause dipper rigidity mutation along its length serious, dipper is easy to send out in impact protector structure end
Raw fracture.
Invention content
The technical problem to be solved by the present invention is to be directed to impact protector structure on existing excavator boom cannot preferably improve
The problem of dipper anticollision, and a kind of excavator boom that can effectively improve dipper anticollision ability is provided.
The present invention is to realize that the technical solution of its purpose is such：A kind of excavator boom is provided, the dipper is main
It is the box-structure being welded by top plate and bottom plate and both side plate, the distance between lateral surface of both side plate is less than the bottom plate
Width；It is characterized in that the bottom surface of the pan front is welded with several gussets, length direction of the gusset in dipper
On be intervally arranged, the length direction of the gusset is vertical with the length direction of the dipper, and the both ends of the gusset are protruding to
The outside that both side plate projects on bottom plate.In the present invention, when ore strikes on gusset, impact force is along the length side of gusset
It transmits to both sides, and then is transmitted on the both side plate of dipper by the both sides of the edge of dipper bottom plate, reduced on dipper bottom plate
Impact force, to effectively play a protective role to dipper；The stress of effect in welded joints, reduces bucket when reducing dipper deformation simultaneously
The risk of bar cracking.
In above-mentioned excavator boom, the gusset is hollow hollow-core construction.The gusset be in trench structure, notch with
The dipper bottom plate is opposite to be bonded.The gusset can be made of channel steel or form groove profile by steel plate bending or welding, into
One step, the gusset of groove profile is closed at both ends, and gusset only mutually welds at its both ends and the bottom plate.This hollow gusset can be very
The impact energy of ore impact dipper is absorbed well, and reduction dipper bottom plate, which is hit, deforms and cause the risk of dipper cracking.
Further, in above-mentioned excavator boom, the top surface of the gusset is bonded with the bottom plate, the top surface of the gusset
On be provided with one or two grooves, the groove extend vertically through the top surface of the gusset in the width direction of the gusset.
When ore hits gusset, gusset is deformed in the position of groove absorbs ore impact energy.Groove on adjacent two gusset
It is mutually staggered on the length direction of gusset, just absorbs the energy for impinging upon each position of dipper.
Compared with prior art, the present invention the present invention has the following advantages：
1, the gusset in the present invention is directly welded on bottom plate, relative to original structure without welding reinforcing plate, realizes weight
It reduces, cost has a degree of decline.
2, gusset can transmit the impact force of ore to dipper both sides in the present invention, effectively reduce in the middle part of dipper bottom plate
Impact force, while the impact energy of ore is effectively absorbed, reduce the injury for dipper.
3, in the present invention, each gusset is smaller and independent, and when failure is easily changed.
4, the length direction of gusset is vertical with the length direction of dipper in the present invention, becomes to the rigidity on bucket arm length direction
It is smaller to change influence, can effectively reduce the dipper cracking risk as caused by being mutated rigidity.

Parts title and serial number in figure：
Bottom plate 1, side plate 2, strengthening version 3, reinforcing rib 4, gusset 5, groove 51.
Specific implementation mode
Illustrate specific embodiment below in conjunction with the accompanying drawings.
Excavator bucket rod structure in the present embodiment as shown in Figure 1, dipper mainly have top plate and bottom plate 1 and both side plate 2 welding and
At box-structure, both side plate 2 be vertically welded in the distance between 2 lateral surface of top surface namely both side plate of bottom plate 1 be less than bottom plate
1 width.The bottom surface of 1 front of bottom plate is welded with several gussets 5, and gusset 5 is intervally arranged on the length direction of dipper, gusset
5 length direction is vertical with the length direction of dipper, and the both ends of gusset 5 are protruding to the outside that both side plate 2 projects on bottom plate,
Namely projection of the both side plate 2 on bottom plate is intersected with the projection of gusset 5 on a base plate 2..This structure can be preferably by mine
The impact force of stone is transferred on the both side plate of dipper, while reducing the stress acted on when dipper deformation in welded joints, reduces dipper
The risk of cracking.
The top surface of gusset 5 is bonded with bottom plate 2, and the structure of gusset is as shown in figure 3, gusset is hollow hollow-core construction, gusset
In trench structure, notch fitting opposite with dipper bottom plate.Gusset can be made of channel steel or by steel plate bending or welding
Groove profile is formed, the gusset of groove profile is closed at both ends, and gusset only mutually welds at its both ends with bottom plate.It is provided with one on the top surface of gusset 5
Item or two grooves 51, groove 51 extend vertically through the top surface of gusset 5 in the width direction of gusset.It is recessed on adjacent two gusset 5
Slot mutually staggers on the length direction of gusset, to absorb the impact energy at each position of dipper.This hollow gusset energy
The impact energy of ore impact dipper is enough absorbed well, and reduction dipper bottom plate, which is hit, deforms and cause the wind of dipper cracking
Danger.When gusset loses the ability for absorbing ore impact energy because ore hits gross distortion, can be incited somebody to action by two end pads of polishing
The gusset of damage removes, and welds intact gusset on dipper again.
In the present invention, when ore strikes on gusset, impact force is transmitted along the length direction of gusset to both sides, in turn
It is transmitted on the both side plate of dipper by the both sides of the edge of dipper bottom plate, reduces the impact force on dipper bottom plate, to effectively right
Dipper plays a protective role.Gusset is deformed when ore impacts simultaneously absorbs ore impact energy, improves the crashworthiness of dipper
Hit ability.
