According to the invention, the hydraulic lifting device is arranged below the target plate, the pressure boosting device stores high-pressure hydraulic oil, and the high-pressure hydraulic oil enters the large oil cylinder through pressing of the handle to push the piston to rise. The upper end of the hydraulic device is in threaded connection with the bottom end of the target plate device, so that the target plate device can be lifted. The universal wheels are arranged at the lower ends of the hydraulic devices, after the target plate device is lifted, the fixing devices at the two sides of the target plate can leave the ground, and the position and the angle of the target plate device can be adjusted. The middle part of the target plate device is provided with two handwheels, the rotation of the handwheels drives the rotation of the turbine welded with the handwheels to drive the rotation of the gears, and the bevel gears on two sides also rotate. The bevel gear can drive the rotation of screw rod, and the dovetail guide rail is installed to the screw rod both sides, and the rotation of screw rod drives the motion of screw rod seat, goes up the frid through the screw fixation with the screw rod seat, goes up the frid and removes in the dovetail guide rail to screw thread transmission has the ability of auto-lock, can realize going up the stop function of frid, is equipped with the screw hole on going up the frid, is used for installing the installation of the fixed upper and lower board of experimental target plate.
The invention is a target plate mounting device for shooting test, as shown in figure 1, mainly comprising: the support frame 1 is welded with the bottom plate of the target frame, and supports the target frame when the hydraulic device does not work. The hydraulic device adopts the principle design of a common manual hydraulic jack and mainly comprises an operating handle 2, a high-pressure oil cylinder 15, an oil return rod 16, a one-way valve 18, a piston 19 and a moving piston 20.
2 is the operating handle of hydraulic means, is connected on hydraulic means through the bolt, forms partial vacuum through upward movement, and the oil in the high-pressure oil cylinder 15 is inhaled the little hydro-cylinder in the handle below through piston 19, and when the handle pushed down, will squeeze hydraulic oil into big hydro-cylinder through check valve 18 to the motion piston 20 rises, and the target plate bottom passes through threaded connection with the top of piston, thereby whole target plate also can carry out the lifting. And 16 is an oil return rod, when the position of the target plate is adjusted and the target plate is to be fixed, the oil return rod 16 is twisted, high-pressure hydraulic oil in the large oil cylinder flows into the liquid storage cylinder 14, the piston descends, the target frame descends, and the support frame 1 contacts with the ground to form a supporting effect on the target frame. The schematic process of the hydraulic device is shown in fig. 2, in which arrows indicate the flow direction of the hydraulic oil.
The transmission part consists of a hand wheel worm 13, a gear 11, a transmission shaft 12, a bevel gear 5, a screw 7 and a screw seat 21. The hand wheel worm 13 is formed by welding a worm and a hand wheel, the worm is arranged in a tapered roller bearing, and the tapered roller bearing can be arranged according to the size requirement by welding a bearing frame from a target frame position, such as a bearing 4. The threaded rod bearing 3 is a rolling bearing which is arranged on the bottom plate of the target frame. The method of mounting the drive shaft 12 is also similar. When the hand wheel worm 13 rotates, the gear 11 also rotates along with the rotation, the bevel gears on two sides of the transmission shaft 12 also start to rotate, the bevel gears 5 and the right bevel gears symmetrical with the bevel gears synchronously rotate, and the rotation directions are different, if one is clockwise, the other is anticlockwise. So in order to realize synchronous rising of the screw bases 21 at the two sides, the screw 7 and the screw at the other side corresponding to the screw are set to different rotation directions, the screw 7 is set to be left-handed, and the screw at the other side corresponding to the screw rotation direction is set to be right-handed. The dovetail groove guide rail 8 forms a base of the screw rod and can be welded and fixed according to the side edge of the target frame. The upper groove plate 6 is fixed with the screw rod seat through a screw rod, and is lifted or lowered on the dovetail groove guide rail 8 (the specific structure is shown in figure 3. When the lifting angle of the screw thread is smaller than the equivalent friction angle of the screw pair, the screw thread transmission has the characteristic of self-locking, so the upper groove plate can be stopped at any height of the screw rod by rotating the hand wheel worm left and right.
The upper plate 9 and the lower plate 10 of the target plate are fixed on the upper groove plates at two sides by screws, the lower plate 10 is used for supporting the weight of the target plate, and the shape and the structure of the two plates are shown in fig. 4. After the upper and lower mounting plates 9 and 10 of the target plate are fixed, a target plate sample is placed therein, and the upper part of the target plate sample is clamped to the rear wall of the upper mounting plate 9 and the lower part of the sample is clamped to the rear wall of the lower mounting plate by using an F-shaped clamp, as shown in FIG. 6.
Two universal wheels 17 are arranged at the bottom of the target frame, the target frame is fixed by screws, and the universal wheels 17 are selected as standard components. When the hydraulic device rises the target frame to a certain height, the support frame 1 is separated from the ground, the universal wheels support the target frame, the shooting distance and the angle can be adjusted, and after the adjustment is finished, the oil return rod is opened to realize the falling of the support frame 1, so that the target frame is fixed.
