Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
Present embodiment discloses a kind of chassis of dredging machine heightening devices, including lower flange 1, cylinder 2, upper method as shown in Figure 1:
Orchid 3, oil sump bottom plate 4, sealing ring 5, bracket 6, support plate 7 and reinforcing rib 8；Bracket 6 is equipped with bracket holes 61；Lower flange 1, upper flange
3 are equipped with several through-holes, and the both ends of cylinder 2 are separately connected lower flange 1 and upper flange 3, and support plate 7 is connected to inside cylinder 2, branch
Board 7 is set between lower flange 1 and upper flange 3, and support plate 7 is parallel to lower flange 1 and upper flange 3, and upper flange 3 connects oil sump
The outer of bottom plate 4, the interior edge connection sealing ring 5 of oil sump bottom plate 4, the upper end of sealing ring 5 is got on the bus by sealing ring connecting excavator
The bottom surface of frame；Bracket 6 is connected to support plate 7；It is bracket holes 61 and lower flange 1, upper flange 3, close when bracket 6 is connect with support plate 7
Seal ring 5 is with one heart；Lower flange 1 is used for connecting excavator chassis, and upper flange 3 is used for connecting excavator pivoting support.
Specifically, the connection relationship between the lower flange 1 of the present embodiment, upper flange 3 and cylinder 2 is welding, support plate 7
Connection relationship between cylinder 2, bracket 6 is welding, and the connection relationship between upper flange 3 and oil sump bottom plate 4 is also welding.
As shown in Figure 3: including inner ring 31 and outer ring 32, through-hole is set to outer ring 32, outer ring for upper flange 3 and lower flange 1
32 thickness is greater than inner ring 31.The roughness of 32 joint face of outer ring is lower than the outer surface of inner ring 31.For upper flange 3,
Joint face is its upper surface, and for being attached with getting on the bus, for lower flange 1, joint face refers to lower surface, for
The one side of chassis connection, inner ring 31 are only needed in processing using rough turn, and the requirement for surface roughness is lower, and reduction is processed into
This.
Specifically, bracket 6 is welded in the upper surface of support plate 7, the angle A range between 6 upper surface of bracket and support plate 7
It is 90-180 degree.
In order to promote the bonding strength between cylinder 2 and lower flange 1, reinforcing rib 8 is additionally provided between cylinder 2 and lower flange 1,
Reinforcing rib 8 is set to the inside of cylinder 2.It is multiple that reinforcing rib 8 has mystery to have, and multiple reinforcing ribs 8 are uniformly distributed along 2 inner wall of cylinder.
In conjunction with Fig. 1 and Fig. 3: in use, upper flange 3 is bolted to the revolving support that excavator is got on the bus, lower flange 1
It is bolted to the chassis of excavator, after connection, center steering body is in the center of cylinder 2, the upper end of center steering body
Connecting bracket hole 61, the upper end of sealing ring 5 pass through the bottom surface of 9 connecting excavator upper frame of sealing ring.Since bracket holes 61 are under
Flange 1, upper flange 3, sealing ring 5 are arranged concentrically, therefore when getting on the bus relative to chassis rotation, will not be produced to center revolving body
Raw damage.
In addition, circular diameter is not less than people's both shoulders distance to facilitate people's maintenance construction and reserve reinforcing rib 8 in lower flange 1
Weld space；2 diameter of cylinder is as big as possible, but bolt mounting holes of 2 periphery of cylinder away from upper flange 1 and lower flange 3 should have foot
Enough spaces, to prevent cylinder 2 and bolt from assembling sleeve interference.Circular diameter should reserve in upper flange 3 and cylinder 2 in upper flange 3
Portion's weld seam welds space and proof strength.
The present embodiment can expand excavator operating condition use scope under the premise of lesser for the change of existing excavator,
The engine that water immerses damage excavator can be kept away；On the other hand, chassis heightening device is able to ascend the height of driver's cabin, enhancing
Operate the visual field.The configuration of the present invention is simple, feasibility is strong, and input cost is low, has a extensive future.
Above are merely preferred embodiments of the utility model, it is noted that for the ordinary skill people of the art
Member for, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these improve and
Deformation also should be regarded as the protection scope of the utility model.
