The specific embodiment
Embodiment one
The oil pump installation of present embodiment and the basic structure of operating mechanism are as shown in Figure 1; Comprise and be installed in the oil pump 7 that is in transmission connection with power takeoff 11 on the oil pump bracket 8; One side of this oil pump is equipped with oil pump variable handle 5; Oil pump bracket 8 is channel steel shape, the steel pipe support arm 15 (referring to Fig. 3) that both sides welding is connected and extends outwardly, and the outer end of two support arms is connected with vertical welding of L shaped otic placode 16 respectively.The horizontal plane of two otic placodes 16 is supported on welding respectively and is fixed on bogie side frame 3 horizontal planes of agitator truck subframe 12, is connected with fastening bolt.Bogie side frame 3 is and reverse L shaped of otic placode 16, have trivet between its horizontal plane and the vertical plane, so rigidity is good.Horizontal rotating shaft cover 25 (referring to Fig. 2 and Fig. 5) that the openend welding of oil pump bracket 8 is connected and installs rotating shaft 24; One end of rotating shaft 24 is connected with the upper end welding of the rotating shaft swing arm 18 that court extends below, and the lower end of rotating shaft swing arm 18 is in transmission connection through flexible axle 1 and connecting rod 4 and the flexible axle controller 30 (referring to Fig. 6) and the oil pump variable handle 5 that are positioned at the agitator truck driver's cabin respectively.Because connecting rod 4 is in transmission connection with rotating shaft swing arm 18 and oil pump variable handle 5 respectively through the spherical hinge at two ends, so the assembly precision requirement is low, motion is transmitted flexibly.The other end of rotating shaft 24 is connected with the fan-shaped connecting plate 17 that court extends below; The curved edge of this connecting plate fan-shaped (referring to Fig. 4) down; Its curved edge has depression spaced apart; The location-plate 20 of the contiguous fan-shaped connecting plate 17 of rotating shaft cover 25 welding extending down is equipped with the spring base 19 of aperture, upper end towards fan-shaped connecting plate curved edge through securing member on this location-plate, this spring base the locking ball 26 that is resisted against on the spring 27 is housed; The top of locking ball 26 is dropped in one of depression, therefore can play the adjusting positioning action of oil pump variable handle 5.One side of spring base 19 has the opening elongated slot as horizon adjustable travel mechanism, regulates the relative position of securing member in elongated slot, can adjust the fixed position of spring base on location-plate as required, thus the open degree of adjustment oil pump variable handle 5.The adjusting bolt 21 that withstands on spring 27 lower ends is equipped with in the bottom of spring base 19, thus pretightning force that can regulating spring.The lower end of connecting plate 17 is in transmission connection through manipulation connecting rods 6 and the afterbody operating grip 31 that is positioned at the agitator truck afterbody.Therefore no matter at driver's cabin,, all can realize controlling easily to oil pump still at the tailstock.In addition, also have spacing mounting hole 29 on the fan-shaped connecting plate 17, be fixed in the spacer pin 22 of spacing mounting hole 29 on the location-plate 20, therefore can limit the extreme position of oil pump variable handle 5.
When stirring operating grip 31 at the vehicle afterbody, when promoting manipulation connecting rods 6, the fanning strip 17 that is driven on the pipe rotating shaft mechanism by ball pivot swings; The rotating shaft swing arm 18 of the rotating shaft other end is also with swing; Drive oil pump variable handle 5 through oil pump rod 4 and turn an angle,, realize changing drum speed and the operation that turns to change pumped oil mass and the oily direction of turnover; Owing on the fanning strip spring steel ball detent mechanism is set; Fanning strip is positioned on the different swing position, makes oil pump variable handle be positioned on the different angle positions, obtain different oil pump feed amounts; Thereby obtain different mixing drum stabilized (steady-state) speeds, when satisfying the trucd mixer operation rotating speed of different operating modes with turn to requirement; Equally, when push-and-pull flexible axle controller level in driver's cabin, also can drive rotating shaft swing arm swing, realize the purpose of control drum speed through flexible axle.
The oil pump installation and the operating mechanism that experiment showed, present embodiment have following outstanding advantage: the oil pump drive spindle setting angle is little, and the power transmission running is steady reliably, efficient is high; Operating mechanism is simple in structure, controls easy and flexible, precision height, safeguards easy to adjust.
Except that the foregoing description, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
