As shown in fig. 4, a screw supporting plate 19 is fixed on the side surface of the platform 13, a screw sleeve 20 is fixed on the screw supporting plate 19, the screw 15 sequentially penetrates through the screw sleeve 20 and the screw supporting plate 19 and then is connected with one end of the lower clamp plate 14, and a hand wheel 22 is fixed at the other end of the screw 15 through a first screw 21.
The main parts of the heavy-load vertical impact test equipment have the following functions:
the foundation bolt 2 prevents the looseness and operation danger of the device caused by improper fixation of the base 1 in the impact process;
the guide plate 5 and the pressing plate 6 enable the punch holder 4 to move only along the direction of the guide rail 3;
the limiting angle steel 10 is used for limiting the position of the punch holder 4, the limiting angle steel 10 is fixed on the guide rail 3 through a screw, and the position of the limiting angle steel 10 can be adjusted;
the balancing weight 11 is used for increasing the weight of the whole device and improving the stability in the impact process;
the screw holes 23 are used for fixing an object to be impacted to the impact-resistant aluminum plate 18;
the upper clamping plate 17 and the lower clamping plate 14 are matched for fixing an impact-resistant aluminum plate 18, so that an impacted object is further fixed, and the stability during impact is ensured;
the screw rod 15 is used for transmitting the rotation of the hand wheel 22 to the lower clamp plate 14 and driving the lower clamp plate 14 and the upper clamp plate 17 to move together, so that the support position of an impacted object is adjusted, and different hand wheels 22 control the lower clamp plate 14 to move in different directions.
When the heavy-load vertical impact test equipment is used, the working process is as follows:
the lower clamping plate 14 is driven to move by rotating the hand wheel 22, and the upper clamping plate 17 corresponding to the lower clamping plate 14 is driven to move simultaneously by the bolt 16. After the upper and lower clamping plates 17 and 14 are moved into position, all the bolts 16 are tightened, thereby tightly fixing the upper and lower clamping plates 17 and 14 and the impact-resistant aluminum plate 18 to the platform 13.
Fixing the object to be impacted on the upper surface of the impact-resistant aluminum plate 18 through the threaded hole 23 by using a screw; moving the position of the punch holder 4 to make the punch 8 align with the middle position of the impact-resistant aluminum plate 18; moving the position of the limit angle steel 10 to enable the limit angle steel 10 to be in contact with the punch seat 4, so that the punch seat 4 is positioned on the guide rail 3; then the screw on the pressing plate 6 is screwed down, so that the pressing plate 6 can hook the lower surface of the guide rail 3, and the punch holder 4 is fixedly connected with the guide rail 3; the hydraulic cylinder 7 pushes the punch 8 to move upwards, impact against the impact aluminum plate 18 is completed, the impact load is transmitted to the impacted object through the impact aluminum plate 18, and therefore impact on the impacted object is completed.
After all the bolts 16 are loosened, the hand wheel 22 is rotated to adjust the distance between the lower clamping plates 14, and at the moment, the distance between the upper clamping plates 17 corresponding to the positions of the lower clamping plates 14 is changed, so that the supporting positions of the impacted objects are changed, and the impact test can be repeatedly carried out at different supporting positions.
