Abstract
The utility model provides a stabilizing mechanism for slewing sealing of a mixing drum. The slewing end of a slewing bearing (4) is fixed on the outer wall of the mixing drum (1); the fixed end of the slewing bearing (4) is in direct or indirect connection with the fixing component of a slewing sealing mechanism. Under the reliable positioning action of the slewing bearing, 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 the problems such as the evaporation of concrete moisture content, layering, Qinshui, improved concrete quality.
Because concrete mixing and transporting car often operates on rough road surface, the rotary sealing mechanism of its mixing drum frequently jolts, upper and lower, forward and backward and left and right respectively to irregular vibration, cause thus the actual gap between gyro black assembly and fixation kit, particularly rotate the gap between inner core end and end cover and design fit clearance always in fluctuation status.The fluctuation status in this gap, when occur by a relatively large margin change time, can cause rotary sealing to lose efficacy, parts damages; And while there is less variation in this gap, can cause component wear, or because of fit clearance fluctuation, cause concrete slurry to enter rotary sealing cavity, cause sealing effectiveness to decline and even lost efficacy.
utility model content
The utility model aims to provide a kind of 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 can remain at more stable state.
The technical scheme that the utility model adopts is as follows:
A kind of 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: also comprise pivoting support, its one end is fixed on as round end on the outer wall of described mixing drum, and the other end is connected with described fixation kit as stiff end, or the other end is connected with described fixation kit by retainer ring as stiff end.
Good effect of the present utility model is:
One end of pivoting support (round end) is connected on the outer wall of mixing drum and rotates with mixing drum, its other end (stiff end) is connected with the fixation kit of rotary sealing mechanism, utilize the reliable position-limiting action of pivoting support, guaranteed that the vehicle gyro black assembly in process that jolts keeps relative fixing with the design fit clearance between fixation kit, thereby both alleviated component wear, guarantee again the sealing effectiveness of rotary sealing mechanism, extended the service life of rotary sealing mechanism.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.In order more clearly to show the utility model, Fig. 1 has adopted disconnect mode, only retains the rear portion of mixing drum, and has omitted the support section of body part and rotary sealing mechanism.
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 3, and described rotary sealing mechanism 3 comprises fixation kit and rotary components.The utility model patent " the rotary sealing mechanism of concrete agitating drum " that the publication number of take is " CN 202781441 U " is example, and described fixation kit comprises ring in end cover, adpting flange, fixed outer cylinder, mounting flange and protection.
Also comprise pivoting support 4, its one end is fixed on the outer wall of described mixing drum 1 as round end, its other end is connected with described fixation kit as stiff end, or its other end is connected with described fixation kit by a retainer ring 2 as stiff end.
During use, one end of pivoting support 4 does not turn, and the other end is with mixing drum 1 rotation.
Claims (1)
