Problems solved by technology
[0003] At present, the solution for the vertical installation of the actuator cylinder is: the installer uses a wire rope to bind the rings on both sides of the upper end of the actuator cylinder to the two ends of the actuator fixed seat. This vertical installation of the actuator can only The rear end earrings of the actuator under tensile load bear the bending moment, which brings uncertain factors to the safety and quality of the actuator under test loading
Moreover, in the structural test, the loading position of each test situation is different, and the loading actuator needs to be frequently disassembled and replaced. The vertical installation process of the existing actuator is cumbersome. The actuator is replaced once, and the steel wire rope is re-bound. The fixing seat of the actuator is once, and the installation workload is large

Embodiment Construction
[0014] Such as figure 1 As shown, the vertical support device of the loading equipment is composed of an adjusting screw 2, a horseshoe-shaped support 3, a connecting plate 4, and a fixing screw 5; the horseshoe-shaped support 3 is the main component, and a pair of horseshoe-shaped supports 3 are used to clamp the double cylinder. The ear base 6 and the rear end earring 1 make the rear end earring 1 only deflect at a limited angle around the vertical direction of the bottom plate of the double ear base 6. Since the height of the rear end earring 1 of the same tonnage actuator is slightly different, by adjusting the support 3 The upper end adjustment screw 2 can adjust the support height of the entire support device and the angle at which the rear end earring 1 deflects in the vertical direction of the double-ear base 6 , and a pair of horseshoe-shaped supports 3 are connected by 4 connecting plates 4 and 8 fixing screws 5 .

The invention relates to a loading equipment supporting device, in particular to a ground vertical supporting device for a hydraulic loading actuating cylinder of airplane structure tests. The loading equipment vertical supporting device comprises a pair of horseshoe-shaped supporting pieces (3), structures and sizes of the supporting pieces are matched with those of a double-ear base of the actuating cylinder, and the horseshoe-shaped supporting pieces (3) clamp the actuating cylinder double-ear base (6) and rear end lugs (1) and are fixed through set screws (5) by means of connecting plates (4). Adjusting screws (2) which are used for adjusting supporting height of the whole supporting device and deflecting angle of the rear end lugs (1) in the vertical direction of the double-ear base (6) are arranged on top of the horseshoe-shaped supporting pieces (3). The loading equipment supporting device is simple, practical and reliable in design, rapid reloading requirements of the airplane structure tests can be met, the stress mode of the rear end lugs of the actuating cylinder can be improved, the test site is orderly arranged, and prospective effects are achieved.
Description
technical field [0001] The invention relates to a supporting device for loading equipment, in particular to a ground vertical supporting device for a hydraulic loading cylinder used in aircraft structure tests. Background technique [0002] In the aircraft structure test, the loading actuator at the downward point of the test piece usually needs to be installed vertically on the ground, while the existing actuator is designed with a movable seat (the rear end ear connected to the actuator cylinder surrounds the actuator base Joint bearing rotation), the cylinder body cannot be placed naturally vertically on the ground after the cylinder base is fixed. [0003] At present, the solution for the vertical installation of the actuator cylinder is: the installer uses a wire rope to bind the rings on both sides of the upper end of the actuator cylinder to the two ends of the actuator fixed seat. This vertical installation of the actuator can only The rear earrings of the actuator ...
