Abstract
The utility model provides a wheeled stabilizing mechanism for slewing sealing of a mixing drum. A spacing guide rail (2) surrounding the mixing drum (1) is mounted on the outer wall of the mixing drum (1); a plurality of spacing axles (6) are mounted on the fixing component of a slewing sealing mechanism (4); spacing wheels in rolling fit with the spacing guide rail (2) are mounted on the spacing axles (6). Under the axial spacing action of the spacing wheels and the axles thereof, the fitting clearance designed between a slewing component and the fixing component during the jolting process of a vehicle is ensured to be relatively fixed, so that component abrasion is reduced, the sealing effect of the slewing sealing mechanism is ensured, and the service life of the slewing sealing mechanism is prolonged.
Description
technical field
The utility model relates to a kind of stabilizing mechanism of rotary sealing, and described rotary sealing refers to for concrete mixing and transporting car, and is arranged on the rotary sealing mechanism of mixing drum feed inlet and outlet end.
background technology
Inventor Sheng Fuchun had once invented a kind of " concrete mixing and transporting car of mixing drum feed inlet and outlet rotary sealing ", and obtain Chinese invention patent mandate, Granted publication CN102029940B, solved the reliable rotary sealing problem of mixing drum input and output material port, meet when reinforced mixing drum all the time in rotation status, and realized the low-angle of mixing drum or horizontally disposed.Make thus concrete mixing and transporting car there is following characteristics: to reduce transport vehicle center of gravity, improved the driving safety of concrete mixing and transporting car, greatly improve trafficability characteristic, and solved concrete water evaporation, concrete delamination, Qinshui problem, improved concrete quality.
Because vehicle frame in concrete mixing and transporting car transportation is ceaselessly to tremble up and down all the time, uneven due to road surface in addition, more aggravated this phenomenon, thereby cause the rotary sealing mechanism of mixing drum, with respect to mixing drum and revolution in ring frequently jolt, and this jolt or upper and lower, forward and backward and left and right each to irregular compound vibration.Design fit clearance between gyro black assembly and fixation kit and actual gap change hour, can cause component wear and concrete slurry to enter rotary sealing cavity, even seepage.When change by a relatively large margin occurs the gap between rotation inner core end and end cover, can cause seal failure, even damage of components.
utility model content
The utility model aims to provide a kind of wheeled stabilizing mechanism of mixing drum rotary sealing, and technical problem to be solved is that, by the support to mixing drum, in the process of jolting, the fit clearance of rotary sealing mechanism remains on more stable state.
The technical scheme that the utility model adopts is as follows:
A kind of wheeled stabilizing mechanism of mixing drum rotary sealing, the mixing drum that comprises concrete mixing and transporting car, the input and output material port of mixing drum is provided with rotary sealing mechanism, described rotary sealing mechanism comprises fixation kit, it is characterized in that: the limit guide rail around mixing drum is installed on the outer wall of described mixing drum, several spacing wheel shafts are installed on described fixation kit, the position-limited wheel that rolls and coordinate with described limit guide rail is installed on described spacing wheel shaft.
Described position-limited wheel comprises at least three uniform bidirectionally limited wheels.
Described position-limited wheel also comprises at least one unidirectional position-limited wheel.
Described fixation kit comprises mounting flange and adpting flange; Within described spacing wheel shaft is positioned at adpting flange through mounting flange and rearward end.
Good effect of the present utility model is:
Limit guide rail of the present utility model is rotated with mixing drum, and position-limited wheel only has not revolution of rotation.Utilize the axial location effect of position-limited wheel and wheel shaft thereof, make rotary sealing mechanism and mixing drum keep relative stable connection location, can guarantee that like this vehicle jolts in process, gyro black assembly keeps relative fixing with the fit clearance between fixation kit, only has very little vibration, thereby both alleviated component wear, guaranteed again the sealing effectiveness of rotary sealing mechanism, extended the service life of rotary sealing mechanism.
The utility model also has simple in structure, stable performance, the outstanding feature manufacture, maintenance cost being low.
accompanying drawing explanation
Fig. 1 is schematic appearance of the present utility model.
Fig. 2 is structural representation of the present utility model.
the specific embodiment
As shown in Figure 1, the utility model comprises the mixing drum 1 of concrete mixing and transporting car, and the input and output material port of mixing drum 1 is provided with rotary sealing mechanism 4, and described rotary sealing mechanism 4 comprises fixation kit and rotary components.Described fixation kit comprises the mounting flange 4-1 shown in Fig. 2, fixedly inner core 4-2 and interconnected adpting flange 4-3 and end cover 4-4.Fixedly the rear and front end of inner core 4-2 is connected with mounting flange 4-1, adpting flange 4-3 respectively, or three is structure as a whole.Described rotary components comprises the rotation inner core 4-5 being connected with mixing drum 1, between the rear end of this rotation inner core 4-5 and the front end face of end cover 4-4, has certain interval.Between rotation inner core 4-5 and mounting flange 4-1, sealing ring 4-6 can also be set, further improve the sealing effectiveness of fixation kit and rotary components.
Space between fixation kit and rotary components is as ring packing cavity 4-7, and inside is provided with a heavy above band, the front end face close contact of the rear end face of rearmost end band and end cover 4-4.The sealing means of ring packing cavity 4-7 comprises following two kinds:
The first: be provided with expandable under water-filling or inflated condition, to be positioned at band outside annular pressure band in ring packing cavity 4-7; Annular pressure band press seal band after expansion makes band and rotation inner tank theca close contact; Annular pressure band after expansion is full of the ring packing cavity 4-7 outside band.
The second: described band is with water-filling or the gas-filled cavity that can make band expand; Band after expansion is full of described ring packing cavity 4-7; The medial surface of band is with wearing layer.
On the outer wall of described mixing drum 1, be provided with around the mixing drum limit guide rail of 1 one weeks 2.Several spacing wheel shafts 6 are installed on described fixation kit, the position-limited wheel that rolls and coordinate with described limit guide rail 2 is installed on described spacing wheel shaft 6.
As Fig. 2, in the present embodiment, within described spacing wheel shaft 6 is positioned at adpting flange 4-3 through mounting flange 4-1 and rearward end, this structure makes position-limited wheel have better stability.
Described position-limited wheel can be at least three and uniform bidirectionally limitedly take turns 3, can be also at least three uniform bidirectionally limited take turns 3 with the combination of at least one unidirectional position-limited wheel 5.So-called bidirectionally limitedly take turns 3 and refer to the hook wheel that straddles in limit guide rail 2 and there are two axial upper limit effects.So-called unidirectional position-limited wheel 5 refers to limit guide rail 2 and contacts and only have the position-limited wheel of single axial upper limit effect.
