Hydraulic suction dredge is the ship that a kind of mud by river bottom or lakebed or seabed is drawn onto spoil hopper.For the water such as coastal, along the lake
Domain dredging and reclamation is used.
The hydraulic suction dredge component that buoyancy tank creeper undercarriage is for hydraulic suction dredge walking comprising driving guide frame.Driving
Include playing the driving structure of driving effect and to play the guide frame of guiding role in guide frame, due to driving structure with lead
It is similar to structure structure, therefore it is referred to as driving guide frame.Wherein, specific structure includes that one end is placed on hydraulic motor, is another
One end is placed on the drive shaft on bearing block；Driving gear is provided in drive shaft, driving gear includes close to hydraulic motor cloth
The first gear set and the second gear close to bearing block arrangement.Drive shaft and bearing block joint need to seal, existing use
Rubber oil sea sealing structure, but the popularization of the application range with hydraulic suction dredge, this amphibious machinery of inadaptability in structure
The problem of harsh environments, it is short that there are service lifes, poor reliability.
Summary of the invention
The utility model aim, which is to provide in a kind of air buoyancy tank crawl walking mechanism, to be driven and guiding axle sealing structure, is had
Large carrying capacity, the compensable feature in gap, the performance of machine increase significantly, and service life is elongated, and reliability becomes strong.
It solves between each kinematic pair as dry friction, the intrusion of the impurity such as external silt causes the resistance of motion big, quick abrasion
Problem.
In order to achieve the goal above, the technical solution adopted in the utility model are as follows: in a kind of air buoyancy tank crawl walking mechanism
Driving and guiding axle sealing structure, are placed on hydraulic motor, the other end is placed on drive shaft on bearing block including one end；Institute
Bearing is provided in the bearing block stated, the other end is placed in the bearing；Driving gear, institute are provided in drive shaft
The driving gear stated includes the first gear close to hydraulic motor arrangement and the second gear close to bearing block arrangement；Positioned at bearing
The left and right both ends of seat are arranged with first bearing flap, second bearing flap, set between first bearing flap and second gear
It is equipped with axle envelope part, is provided with floating sealing ring, a left side for the floating sealing ring in drive shaft between axle envelope part and first bearing flap
Side is resisted against at the interior step of axle envelope part, right side is resisted against at the interior step of first bearing flap.
Further, the floating sealing ring is integrally in cylindrical toroidal, and annular groove is offered on the outer peripheral surface of floating sealing ring, described
Annular groove notch from axle envelope part across to first bearing flap.
Further, the first protrusion against first bearing flap left end is vertically arranged in annular groove.
Further, the second protrusion against axle envelope part right end is vertically arranged in annular groove.
The utility model has the technical effect that drive shaft one end is connect with hydraulic motor, the other end by bearing seat supports,
Hydraulic motor drives drive shaft turns, is equipped with bearing in bearing block, relative motion between drive shaft and bearing block.This is practical new
Existing rubber oil sea structure is improved to seal using floating sealing ring by type, has large carrying capacity, the compensable feature in gap, machine
The performance of device increases significantly, and service life is elongated, and reliability becomes strong.

Fig. 2 is the A-A cross-sectional view of Fig. 1；
Fig. 3 is the partial enlarged view of Fig. 2；
Fig. 4 is the cross-sectional view of the stereoscopic-state of the utility model bearing block part.
Specific embodiment
It referring to attached drawing, is driven in a kind of air buoyancy tank crawl walking mechanism and guiding axle sealing structure, including one end is placed on
On hydraulic motor 2, the other end be placed on the drive shaft 1 on bearing block 3；Bearing 4 is provided in the bearing block 3, it is described
The other end is placed in the bearing 4；Driving gear is provided in drive shaft 1, the driving gear includes close to hydraulic horse
First gear up to 2 arrangements and the second gear close to the arrangement of bearing block 3；Left and right both ends positioned at bearing block 3 are arranged with first
Pedestal cap 6, second bearing flap 7 are provided with axle envelope part 9, drive shaft 1 between first bearing flap 6 and second gear
Upper that floating sealing ring 5 is provided between axle envelope part 9 and first bearing flap 6, the left side of the floating sealing ring 5 is resisted against axle envelope part
At 9 interior step, right side is resisted against at the interior step of first bearing flap 6.
Further, it is in cylindrical toroidal that the floating sealing ring 5 is whole, offers annular groove on the outer peripheral surface of floating sealing ring 5, institute
The notch for the annular groove stated is from axle envelope part 9 across to first bearing flap 6.
Further, the first protrusion against 6 left end of first bearing flap is vertically arranged in annular groove.
Further, the second protrusion against 9 right end of axle envelope part is vertically arranged in annular groove.
As it is shown in the figures, 1 one end of drive shaft is connect with hydraulic motor 2, the other end is supported by bearing block 3, hydraulic motor 2
