Abstract
The utility model discloses a rotating device of a dump truck, and the rotating device comprises a rotating shaft which is welded onto an auxiliary frame and a rotating support which is matched with two ends of the rotating shaft and is welded onto a compartment soleplate, wherein the two ends of the rotating shaft are respectively and fixedly provided with a movable connection shaft which can be inserted into the rotating shaft through a pin shaft, and a bushing which is matched with the rotating support is sleeved outside the movable connection shaft. When the compartment is in normal working state, the overturning operation of the compartment rotating support with the rotating shaft can be realized through the matching of a self-lubricating bearing, the rotating support is firmly welded onto the compartment soleplate, the rotating shaft is welded onto the auxiliary frame, a guiding effect on the rotating support can be realized, the overturning operation can be easily realized through the self-lubricating bearing, the structure is stable, and the reliability in overturning can be realized. When the compartment is lifted down to repair, only the pin shaft is required to be disassembled, and then a half shaft is pulled out, so that the compartment can be easily disassembled. The rotating device of the dump truck is reliable and stable in structure and is easy to disassemble.
Description
Technical field
The utility model relates to a kind of dumping truck turning gear, and specifically a kind of dumping truck casing lifting trip shaft, cover adapting device belong to field of mechanical technique.
Background technology
Present dumping truck turning gear all can not guarantee that realization is detachable under the high-intensity prerequisite; When the compartment need hang down maintenance or change; What adopt usually is to the destructive dismounting mode of turning gear, and indivedual detouchable structures can't satisfy daily high-intensity operating needs again.
Summary of the invention
To the deficiency that prior art exists, the utility model technical matters to be solved is, provides a kind of and can guarantee high strength, can realize detachable function again, and reusable dumping car turning gear.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of dumping car turning gear; Comprise the axis of revolution that is welded on the subframe and cooperate with said axis of revolution two ends, be welded in the pivoting support on the cabin floor; Said axis of revolution two ends are fixed with the flexible connection axle that can insert in the axis of revolution through bearing pin, are connected to the sleeve pipe that matches with said pivoting support at the flexible connection outer shaft sleeve.
Above-mentioned dumping car turning gear, said pivoting support bottom is provided with the reinforced seat with the subframe welding.
Above-mentioned dumping car turning gear is welded with the protection channel-section steel on the subframe on said axis of revolution top.
The advantage of the utility model novel dump lorry turning gear is:
1, when the compartment normal operation; The compartment pivoting support is through the cooperation realization of self-lubricating bearing and the upset operation of axis of revolution, and what pivoting support was firm is welded on the cabin floor, and axis of revolution is welded on the subframe; And pivoting support there is directional tagging; Easily realize the operation of overturning through self-lubricating bearing, Stability Analysis of Structures, upset is reliable.
2, when the compartment need hang down maintenance, only need bearing pin is taken off, the simple operations of again semiaxis being extracted can easily be removed.
The utility model compared with prior art has the following advantages and good effect: reliable in structure, stable, can realize easy removal.
Description of drawings
Fig. 1 is the structural representation that the utility model cooperates with said subframe.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details;
As shown in Figure 1; A kind of dumping car turning gear; Comprise the axis of revolution that is welded on the subframe 12 and cooperate with said axis of revolution 2 two ends, be welded in the pivoting support 3 on the cabin floor; Axis of revolution 2 two ends are fixed with the flexible connection axle 5 that can insert in the axis of revolution through bearing pin 4, outside flexibly connecting axle 5, are socketed with the sleeve pipe 6 that matches with said pivoting support 3.In order to realize the high strength of axis structure, the utility model has adopted high strength casing assembly two ends to insert the structure that flexibly connects axle 5, for improving single-piece rigidity, is provided with the reinforced seat 7 with subframe 1 welding in the bottom of pivoting support 3.Be welded with the protection channel-section steel on the subframe on axis of revolution top.Adopt cast steel structure loss of weight design bearing, reduced weight in the time of proof strength.When the compartment need overturn, be support with the axis of revolution, lubricated through the self-lubricating cover is that center of gyration overturns and falls after rise with the circular hole center of pivoting support.Its axis body has been selected a kind of detachable flexible connection axle 5 freely for use, flexibly connects axle 5 also with bearing pin 4 fixed combination axis structures through being fixed on to it to insert in sleeve pipe 6 on subframe 1.Pivoting support 3 adopts the high cast steel structure of intensity.The upset operation in compartment during both cooperation realization work through self-lubricating bearing.When the compartment need hang down when maintenance, only need bearing pin 4 is taken off, will flexibly connect spools 5 simple operationss of extracting again can easily remove.Can reuse again after reinstalling.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
Claims (3)
1. dumping car turning gear; Comprise the axis of revolution that is welded on the subframe and cooperate with said axis of revolution two ends, be welded in the pivoting support on the cabin floor; It is characterized in that: said axis of revolution two ends are fixed with the flexible connection axle that can insert in the axis of revolution through bearing pin, are connected to the sleeve pipe that matches with said pivoting support at the flexible connection outer shaft sleeve.
