Slew gear of the prior art, mostly comprise hydraulic motor, rotary reducer, pinion and external tooth type pivoting support, wherein the Internal and external cycle of pivoting support is fixedly connected with vehicle frame platform with turntable respectively; Rotary reducer is by fluid motor-driven, and drive the pinion engagement external tooth type pivoting support of its output to rotate, to reach the object that turntable rotates relative to vehicle frame platform, this slew gear operates steadily, but there is following shortcoming:
1) expensive: hydraulic motor and rotary reducer have higher requirement for machining accuracy and sealing, make its manufacturing cost very high;
2) lubricating difficulties: for external tooth type pivoting support, it needs the position of lubrication except between Internal and external cycle, also comprise between external gear pump, for the lubrication between its Internal and external cycle, the form of general employing lubricator cup shot lubrication fat, but because its gabarit has gear, therefore lubricating cup can only be placed in pivoting support inner ring, thus in greasing often because of structural member covering or block and affect the injection of lubricating grease; For the lubrication of external gear pump, adopt the mode of manually smearing at present always, but the restriction by structure space makes lubricating grease can not be applied on all mesh tooth faces, lubricant effect is bad, and lubricating grease is often extruded and flows on vehicle frame in gears meshing rotation process, Contaminated Parts and operating environment.
Summary of the invention
The utility model provides a kind of rotary mechanism of bridge inspection vehicle, can under the condition not using hydraulic motor and rotary reducer, realizes that slew gear is safe and reliable, even running, reduces manufacturing cost; Convenience and high-efficiency pivoting support is lubricated.
For achieving the above object, a kind of rotary mechanism of bridge inspection vehicle, comprises vehicle frame platform, pivoting support and turntable, also comprises angling cylinder and checkout gear, described vehicle frame platform is the skeleton construction by crossbeam and longitudinal beam welding, its upper surface is fixedly connected with a bearing connecting axle; Described pivoting support is Non-tooth type structure, and its inside and outside circle is fixedly connected with turntable with vehicle frame platform respectively, and the external surface peripheral of its outer ring has multiple lubrication hole; Described turntable base plate is evenly equipped with the installing hole be connected with pivoting support, its base plate also has an engaging lug, the distance at the pin shaft hole center line distance pivoting support center of this engaging lug is greater than pivoting support outer radii; The two ends of described angling cylinder respectively with the bearing connecting axle of vehicle frame platform and the engaging lug of turntable base plate hinged, its locating distance is the distance of bearing connecting axle to turntable base plate engaging lug of turntable vehicle frame platform when going to 90 °, and adjustable; Described checkout gear comprises induction installation and controller, and launch detection signal induction installation is in order to be in 0 ° and 90 ° of two extreme positions during at turntable to controller, controller is in order to judge the matching of described feedback signal and preset data.
The locating distance of angling cylinder can realize being not less than ± adjustment of 1mm.
Outer ring is provided with grease fitting to pivoting support.
Induction installation is travel switch.
Compared with existing equipment, this rotary mechanism of bridge inspection vehicle, angling cylinder drives turntable to rotate under the driving of hydraulic oil, induction installation is launched detection signal and is arrived controller, controller judges and then controls angling cylinder, and having checkout gear to judge, whether turntable turns round puts in place, under the condition not using hydraulic motor and rotary reducer, achieve that slew gear is safe and reliable, even running, reduce manufacturing cost; Pivoting support is Non-tooth type structure, and installs grease fitting in its outer ring, can realize directly to pivoting support grease up, easy to operate.

Fig. 2 is the plan structure figure of Fig. 1;
Plan structure figure when Fig. 3 is Fig. 1 duty.
In figure: 1, vehicle frame platform, 2, pivoting support, 3, turntable, 4, angling cylinder, 5, checkout gear, 11, bearing connecting axle, 31, engaging lug.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, 2, this rotary mechanism of bridge inspection vehicle, comprises vehicle frame platform 1, pivoting support 2 and turntable 3, also comprises angling cylinder 4 and checkout gear 5, described vehicle frame platform 1 is the skeleton construction by crossbeam and longitudinal beam welding, its upper surface is fixedly connected with a bearing connecting axle 11; Described pivoting support 2 is Non-tooth type structure, and its inside and outside circle is fixedly connected with turntable 3 with vehicle frame platform 1 respectively, and the external surface peripheral of its outer ring has multiple lubrication hole; Described turntable 3 base plate is evenly equipped with the installing hole be connected with pivoting support 2, its base plate also has an engaging lug 31, the distance at pin shaft hole center line distance pivoting support 2 center of this engaging lug 31 is greater than pivoting support 2 outer radii; The two ends of described angling cylinder 4 respectively with the bearing connecting axle 11 of vehicle frame platform 1 and the engaging lug 31 of turntable 3 base plate hinged, its locating distance is the distance of turntable 3 bearing connecting axle 11 to turntable 3 base plate engaging lug 31 of vehicle frame platform 1 when going to 90 °, and adjustable; Described checkout gear comprises induction installation and controller, and launch detection signal induction installation is in order to be in 0 ° and 90 ° of two extreme positions during at turntable 3 to controller, controller is in order to judge the matching of described feedback signal and preset data.
For avoiding because the factors such as vehicle frame platform 1 welding deformation or hinge connecting hole machining accuracy cause angling cylinder 4 assembly precision to reduce, the locating distance of angling cylinder 4 can realize being not less than ± adjustment of 1mm.
Grease fitting is installed in the outer ring of pivoting support 2, can directly to pivoting support 2 grease up, easy to operate.
Induction installation can be travel switch, proximity switch, ultrasonic range finder, laser range finder or infrared range-measurement system, and preferred travel switch, repeatable accuracy is high.
As shown in Figure 3, when bridge inspection vehicle returns back to duty by the state of returning the vehicle to the garage and knock off, angling cylinder 4 drives turntable 3 to rotate under the driving of hydraulic oil, when turntable 3 goes to 90 °, induction installation is launched detection signal and is arrived controller, and the continuation that controller judged and then controlled angling cylinder 4 is shunk and to next action with authority; Equally, when turntable 3 need to be back to return the vehicle to the garage and knock off state time, angling cylinder 4 does extend action, drives turntable 3 to follow pivoting support 2 and rotate, and having checkout gear to judge, whether turntable 3 turns round puts in place; When turntable 3 is still in 0 ° and 90 ° of two extreme positions, then hydraulic jack and checkout gear realize the double limitation of turntable 3 jointly, safe and reliable.
