Description
Technical field
The utility model belongs to Machine Manufacturing Technology, is related to large water conservancy hydroelectric engineering grinding concrete construction with double steel wheels
The water-tight equipment of vibrated roller.
Background technique
Existing grinding concrete construction selects dual-steel wheel road roller as crucial compacting equipment, and all both at home and abroad
Road roller is mainly practically applicable to construction of the highway, and the sealing system of spring bearing is isolated mainly for dust and is set, to mixed for rolling
The sealing means such as labyrinth seal, felt seal, boxlike combination sealing are usually arranged in the road roller of solidifying soil construction, are all to bearing
End face is sealed, but has a circle connection gap between axial top chock and steel wheel body, and cement slurry still can be from above-mentioned
Gap in enter bearing, influence the lubrication of spring bearing, make the spring bearing service life decline 80%, reduce equipment service efficiency,
Improve the use cost of equipment.
Summary of the invention
The purpose of the utility model is to overcome the existing insecure defects of dual-steel wheel road roller sealing device, propose one kind
Reinforce bearing axial seal, leakproofness is reliably used for the water-tight equipment of dual-steel wheel road roller.
Technical solution used by the utility model is a kind of water-tight equipment for dual-steel wheel road roller, and main points exist
In: it is made of flexible inner ring and rigid external collar, support leg is fixed on rigid external collar.
The utility model is used to support the ring type seal outside bearing block, is wrapped in outside supporting bearing base, and inner ring is soft
Property and wear-resisting, well by the gap sealing between bearing block and steel wheel shaft, prevents the impurity such as cement slurry from entering damage bearing,
Sealing ring can be fixed on well in steel wheel shaft by rigid external collar.
The support leg is L shape, and the flexibility inner ring is fixed on the inner peripheral surface of outer ring, and support leg is fixed on outer ring
Outer circumference surface on.
At least there are three support legs, and support leg is uniformly distributed along the circumference.
Benefit is fixed by bolts to outside the support of dual-steel wheel road roller oscillating column pump side spring bearing support leg when in use, is made
When be made of castable rubber in rigid external collar, flexibility inner ring rotationally wraps up the cylindrical peripheral of bearing block when use.
Utility model has the advantages that ring type seal is made of rubber and metal, manufacturing cost is low；The device only needs
It is installed using bolt, is not required to that installation, fixed structure is in addition arranged, it is easy for installation；Ring type seal blocks cement
Slurry enters in bearing, and sealing effect is good；Spring bearing is hardly damaged, long service life.
Detailed description of the invention
Fig. 1 is the utility model use state cross-sectional view
Fig. 2 is the structural schematic diagram of the utility model
Fig. 3 is the side half sectional view of Fig. 2
Wherein: 1- sealing ring, 11- inner ring, the outer ring 12-, 13- support leg, 2- bearing block, 3- steel wheel shaft, 4- felt are close
Sealing, 5- cartridge seal part, the gap 6-, 7- bolt, 8- bearing.
Specific embodiment
The utility model is described in detail below with reference to view, cited embodiment can make the skill of this profession
Art personnel more understand the utility model, but do not limit the utility model in any form.
As shown in Figure 1 to Figure 3, bearing 8 is equipped between the steel wheel shaft 3 and bearing block 2 of dual-steel wheel road roller, bearing 8
Sealing is made of felt seal part 4 and cartridge seal part 5, and there is a circle gap 6 in the junction between bearing block 2 and steel wheel shaft 3,
One the utility model -- ring type seal 1 is installed on bearing block 2, cement slurry is stopped to enter bearing 8.The utility model is by soft
Property inner ring 11 and rigid external collar 12 form, flexible inner ring 11 is made of flexible sealing materials such as rubber, stops the impurity such as cement slurry
Gap 6 between bearing block 2 and steel wheel shaft 3 enters and damages bearing 8.The circle made of metal of rigid external collar 12
Ring, flexibility inner ring 11 made of rubber are fixed on the inner peripheral surface of outer ring by casting, and support leg 13, which is fixedly welded, to be fixed on
On the outer circumference surface of outer ring 12, at least there are three the support leg 13 that is uniformly distributed along the circumference, 4 L shape support legs 13 have been welded in figure,
The vertical end of support leg L shape is fixed in steel wheel shaft 3 when use.
The utility model structure size are as follows: the internal diameter of rigid external collar 12 is 50mm bigger than the outer diameter of bearing block 2, rigid external collar 12
Length it is 80mm shorter than the length of bearing block 2, the length of flexible inner ring 11 is 10mm longer than the length of bearing block 2, flexible inner ring 11
45 ° of outer subtended angle degree or so of left and right ends lip, the installation bolt aperture size of support leg L shape is installed than steel wheel shaft 3
The big 1mm of the diameter of bolt, the installation bolt hole distributed dimension and steel wheel shaft 3 of support leg L shape install bolt distributed dimension size
Unanimously.
The utility model, which is installed on dual-steel wheel road roller, to be carried out 1500 hours opening and inspecting after testing under construction simulation environment,
Find no the sign that cement slurry penetrates into former sealing system.According to open and inspect situation see blocked completely cement slurry infiltration
Channel.The completely new dual-steel wheel road roller for not installing ring type seal occurs as soon as cement slurry for 1000 hours in operation and penetrates into sealing system
The a series of serious damages such as sealing system destruction, bearing failure, the damage of vibrating hydraulic pump, support base damage are caused in system and bearing
Bad failure.
Remaining not described part is same as the prior art.
