At present, the truck-mounted crane body frame structure for automotive is big, and load is big.And as the important composition parts of truck-mounted crane, characteristics such as its rigidity and fatigue lifetime will produce significant impact to the truck-mounted crane whole aircraft reliability, it be carried out experimental study be necessary.The method of a kind of bench test of the creationary proposition of the utility model, this method has than carry out the vehicle frame test with the truck-mounted crane car load that controllability is strong, with clearly defined objective, influence is because of obvious advantage such as concentrated.
Summary of the invention
At above-mentioned existing technical matters, the utility model provides a kind of truck-mounted crane vehicle frame bench test device, can be used to the various operating modes of simulated automotive crane when hanging object and hang the thing rotation, is convenient to parameters such as research and analysis stress, distortion.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of truck-mounted crane vehicle frame bench test device, comprise the truck-mounted crane vehicle frame, be installed in vehicle frame revolution turntable and four horizontal support legs on the truck-mounted crane vehicle frame, four hydraulic actuators, four force transducers, four ball pivots, and test frock center support; The truck-mounted crane vehicle frame flips upside down, and the center of vehicle frame revolution turntable is installed on the test frock center support, and four hydraulic actuators and force transducer mounted thereto respectively are fixedly attached to the end of corresponding horizontal support legs by corresponding ball pivot.
Further, truck-mounted crane vehicle frame, horizontal support legs and vehicle frame revolution turntable are pressed the actual condition assembling.
Further, the horizontal support legs length of stretching out from the truck-mounted crane vehicle frame is consistent with actual condition.
Principle of work of the present utility model: during test, the overturning of truck-mounted crane vehicle frame is downward, and its centre of gyration place is fixed on the test frock center support, is used to simulate the upper frame part of crane.Four hydraulic actuators are used for the vertical leg of simulated automotive crane, and the load that hydraulic actuator applies is used for the simulated automotive crane and hangs suffered support reaction on object and when revolution vertical leg.Four ball pivots are used for effectively solving to be tested the horizontal support legs displacement deformation and causes the problem that horizontal direction changes.
The test-bed that hydraulic actuator and correlation test frock are formed, can pass through truck-mounted crane vehicle frame and horizontal support legs imposed load, come simulated automotive crane its vehicle frame and suffered dynamic load and the static load of horizontal support legs when hanging object and hang the thing rotation, and strain and the distortion of testing some positions on vehicle frame and the horizontal support legs.Both can simulate static load and dynamic load, can simulate extreme operating conditions such as three outrigger supports again, can also carry out torture test etc.
The beneficial effects of the utility model are: the mode of utilizing simulation vertical leg support reaction to load, effectively carry out the quiet dynamic operation condition of truck-mounted crane vehicle frame and horizontal support legs by test-bed, test such as extreme operating condition and tired operating mode, the process of the test controllability is strong, approach actual condition, test findings can reflect the actual performance of support body, is convenient to parameters such as research and analysis stress, distortion.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises truck-mounted crane vehicle frame 1, is installed in vehicle frame revolution turntable 7 and four horizontal support legs 2 on the truck-mounted crane vehicle frame 1, four hydraulic actuators 5,4, four ball pivots 3 of four force transducers, and test frock center support 6; Truck-mounted crane vehicle frame 1 flips upside down, and the center of vehicle frame revolution turntable 7 is installed on the test frock center support 7, and four hydraulic actuators 5 and force transducer 4 mounted thereto respectively are fixedly attached to the end of corresponding horizontal support legs 2 by corresponding ball pivot 3.Wherein, truck-mounted crane vehicle frame 1, horizontal support legs 2 and vehicle frame revolution turntable 7 are pressed the actual condition assembling, and the length that horizontal support legs 2 stretches out from truck-mounted crane vehicle frame 1 is consistent with actual condition.
Embodiment 1: the test when simulating three outrigger supports
Truck-mounted crane is in the lift heavy operation process, the state that three outrigger supports may occur, be one of them vertical leg do not stress or be called unsettled, this moment can by actual measurement in addition three vertical leg support reaction or obtain the support reaction size of three vertical leg in addition by Theoretical Calculation.
During test, assemble tested truck-mounted crane vehicle frame 1 and horizontal support legs 2, hydraulic actuator 5, force transducer 4 and correlation test frock by the utility model content earlier.Putting on respective loads on the vertical leg by hydraulic actuator 5 simulation on the test-bed, with parameters such as the strain at testing automobile crane frame 1 and horizontal support legs 2 relevant position places, displacements.
Embodiment 2: simulation test and torture test during the revolution of simulation lift heavy thing
Truck-mounted crane is in the lift heavy operation process, and the revolution of lift heavy thing is common a kind of operating mode, and the support reaction situation of change that is reflected on the supporting leg is that four support reactions on the supporting leg constantly change along with the difference of weight position.This moment can be by support reaction of surveying four vertical leg or the support reaction size variation situation that obtains four vertical leg by Theoretical Calculation.
During test, assemble tested truck-mounted crane vehicle frame 1 and horizontal support legs 2, hydraulic actuator 5, force transducer 4 and correlation test frock by the utility model content earlier.Simulating the corresponding dynamic change load that puts on the vertical leg by hydraulic actuator 5 on the test-bed, truck-mounted crane vehicle frame 1 and horizontal support legs 2 stressed situations of change during the revolution of simulation lift heavy thing.Circulation repeats to load this curve of load, can realize simulation test fatigue lifetime of truck-mounted crane vehicle frame 1 and horizontal support legs 2.
