Description

Tractor suspender load-carrying capacity testing table
Technical field
The utility model belongs to agricultural equipment overall test apparatus field, relates to a kind of tractor suspender load-carrying capacity testing table.
Background technology
At present, the tractor suspender load-carrying capacity testing table of using always both at home and abroad adopts the version that manual loading or oil cylinder hydraulic device load mostly.The manual loading running time, measurement long, data was both inconvenient with collection, again out of true; Cylinder system loads can not guarantee that loading direction is perpendicular to the ground all the time constant, influences the accuracy of measurement data equally; Cylinder system loads and can not make load keep constant, must load with counterweight and carry out quiet settling test.
The utility model content
The purpose of this utility model be to provide a kind of functional reliability good, simple in structure, use easy to maintenancely, the shop test equipment one tractor suspender load-carrying capacity testing table of can connect fast, loading and experimental data being gathered.
The technical solution of the utility model is: tractor suspender load-carrying capacity testing table comprises draw-gear, tested vehicle, load cylinder slide rail system, hanging frame device, loads system, loads to be the move left and right drive unit, loads counterweight system, Hydraulic Station, loading counterweight lifting system, data acquisition and measuring system.Draw-gear is installed in the front end of tested vehicle, the hanging frame device is installed in the rear end of tested vehicle, the hanging frame device is to be connected with loading, loading is that the move left and right drive unit is installed in the load cylinder slide rail and fastens, and with load system and be connected, loading counterweight system is to be connected with loading the counterweight lifting directly, Hydraulic Station is by oil pipe and load system and load counterweight lifting system and is connected, data acquisition and measuring system with loading system, to load be that sensor, controlled unit during move left and right drive unit, Hydraulic Station, the lifting of loading counterweight are links to each other.
Loading is that the move left and right drive unit adopts closed-loop control, makes to load loading direction that system applies all the time vertically downward.
Electrohydraulic proportional control valve in the Hydraulic Station, hydraulic control one-way valve, solenoid directional control valve are connected with data acquisition and measuring system, and Hydraulic Station is to link to each other with loading, and the load that loading system is applied keeps constant.
The utility model adopts the good effect that produces after the technique scheme to be: by hanging frame device, loading system, loading is move left and right drive unit, data acquisition and measuring system, the load of simulation loading on the tractor suspender, adopt closed-loop control, the direction that guarantees loading force is perpendicular to the ground all the time, load-carrying capacity to the tractor suspender is examined, and the hydraulic jack of employing loads the multiple spot continuous coverage that can realize in the process of the test; Data acquisition and measuring system are come control loaded system by electrohydraulic proportional control valve, hydraulic control one-way valve, solenoid directional control valve in the control Hydraulic Station, loading system can be applied made the needed permanent load of vehicle, replace loading counterweight system and carry out quiet settling test.
Description of drawings
Fig. 1 is the structural representation of the utility model tractor suspender load-carrying capacity testing table.
Embodiment
Present embodiment as shown in Figure 1, tractor suspender load-carrying capacity testing table, comprise that draw-gear 1, tested vehicle 2, load cylinder slide rail are 3, hanging frame device 4, to load be 5, to load be move left and right drive unit 6, load that counterweight is 7, Hydraulic Station 8, load that the counterweight lifting is 9, data acquisition and measuring system 10.Draw-gear 1 is installed in the front end of tested vehicle 2, hanging frame device 4 is installed in the rear end of tested vehicle 2, hanging frame device 4 and loading are 5 to be connected, loading is that to be installed in the load cylinder slide rail be on 3 to move left and right drive unit 6, and be 5 to be connected with loading, loading counterweight and be 7 is 9 to be connected with the lifting of loading counterweight directly, Hydraulic Station 8 is 5 to be 9 to be connected with loading the counterweight lifting by oil pipe and loading, and data acquisition and measuring system 10 and loading are 5, loading is a move left and right drive unit 6, Hydraulic Station 8, the lifting of loading counterweight is the sensor in 9, controlled unit links to each other.Loading is that move left and right drive unit 6 adopts closed-loop controls, make load be 5 loading directions that apply all the time vertically downward.Electrohydraulic proportional control valve 11 in the Hydraulic Station 8, hydraulic control one-way valve 12, solenoid directional control valve 13 are connected with data acquisition and measuring system 10, and Hydraulic Station 8 is 5 to link to each other with loading, and can make that to load be that the 5 load maintenances that apply are constant.
Ground is fixed in by draw-gear 1 in tested vehicle 2 front portions, hanging frame device 4 is installed on the rear end hanging bar of tested vehicle 2, hanging frame device 4 and loading are 5 to be connected, by regulate to load be in 5 hydraulic jack pressure to imposed load on the hanging frame device 4, loading is that to be installed in the load cylinder slide rail be on 3 to move left and right drive unit 6, and be 5 to be connected with loading, loading is that move left and right drive unit 6 adopts closed-loop control, make that to load be 5 perpendicular to the ground all the time, the loading direction that assurance applies all the time vertically downward, overcome the loading direction that applies vertical version not perpendicular to the ground, the test figure that records is more near tractor field working condition.It is 5 that data acquisition and measuring system 10 are come control loaded by electrohydraulic proportional control valve 11, hydraulic control one-way valve 12, solenoid directional control valve 13 in the control Hydraulic Station 8, make that to load be 5 can apply and made vehicle 2 needed permanent loads, replace loading counterweight and be 7 and carry out quiet settling test.Load counterweight and be 7 when being connected, detect the lifting time of tested vehicle 2 suspenders, also can do the quiet settling test that is made vehicle with hanging frame device 4.Data acquisition and measuring system 10 realize automatic loading, data acquisition, processing, preservation, printing by system software controls.
