The vibrating device is characterized in that a ring-shaped piece is arranged below the vibrating piece, an eccentric wheel driven by a motor is further arranged in the supporting frame, the ring-shaped piece is sleeved on the eccentric wheel, and a gap is reserved between the ring-shaped piece and the eccentric wheel. When the eccentric wheel rotates, the vibrating piece and the frame can be driven to vertically reciprocate, and the effect of simulating road vibration is achieved.

The heavy object frame is arranged in the middle of the test table board 1 and located on one side of a connecting line of the two vibration devices 4, and collision interference between the heavy object frame and the vehicle frame when the vehicle frame is installed is avoided.

As shown in fig. 2, the weight frame includes a base 5, an upright 6, a lifting ring 7, a lifting cylinder 8, an outer edge block 9, an insert rod 10 and a storage frame 11. The base 5 is installed on test table face 1, pole setting 6 is vertical to be fixed on base 5, the lifting ring 7 rotates the cover and establishes on pole setting 6, lifting cylinder 8 also installs on base 5, lifting cylinder 8 drives lifting ring 7 follows 6 vertical motion in pole setting, connect the setting along piece 9 outward and be in one side of lifting ring 7's top, be provided with the vertical through-hole that link up on the piece 9 of outer edge, inserted bar 10 passes through the vertical slip of through-hole is inserted and is established on the piece 9 of outer edge, the upper end of inserted bar 10 is provided with prevents inserted bar 10 and the annular cap that outer edge piece 9 breaks away from each other. Accomodate frame 11 and connect the setting and be in the below of outer edge piece 9, accomodate and be provided with a plurality of vertical arc storage plate 12 of arranging on the frame 11, arc storage plate 12 is the plate body of level extension, and is a plurality of one side interconnect of arc storage plate 12.

The heavy object block 3 is in a horizontal disc shape, and a corresponding basket body structure on the frame can accommodate the heavy object block 3 during testing. As shown in fig. 3, the weight block 3 is provided with a vertically through insertion hole 13 and a horizontally through arc-shaped receiving hole 14. When the heavy object blocks 3 need to be stored, the inserting rods 10 are correspondingly inserted into the inserting holes 13, the arc storage plates 12 are correspondingly inserted into the arc storage holes 14, and the heavy object blocks 3 are fixedly stored in the storage rack 11.

The utility model discloses a working method as follows: fix the frame on the vibrating device 4 at both ends, adjust the position of accomodating frame 11 through first sliding block 17, second sliding block 18 and lift ring 7, make heavy object piece 3 on accomodating frame 11 correspond to be located the frame and put the thing department directly over, start lift cylinder 8 afterwards, make accomodating frame 11 downstream, until the thing department of putting that heavy object piece 3 of bottommost falls on the frame, then move the inserted bar 10 upwards to suitable position according to the quantity of heavy object piece 3 that needs, rotate lift ring 7 afterwards, make the heavy object piece 3 of required quantity break away from and accomodate frame 11, put back inserted bar 10 downwards, start lift cylinder 8 and drive and accomodate frame 11 upward movement, and will accomodate frame 11 and rotate to one side. After the frame test is accomplished, change back and accomodate frame 11, start lift cylinder 8 and drive and accomodate frame 11 downstream to one side of well heavy object piece 3, upwards take out inserted bar 10, through rotating lift ring 7 and make arc accomodate board 12 insert in arc accomodates hole 14, put down inserted bar 10 and make it insert in jack 13, start lift cylinder 8 once more and can take back the heavy object piece 3 of placing on the frame.

The vertical height of the arc accommodating hole 14 is larger than the thickness of the arc accommodating plate 12, so that the heavy object block 3 is more conveniently separated from the accommodating frame 11 when the heavy object block 3 is placed on the frame.

The thicknesses of a plurality of the weight blocks 3 are the same, the arrangement interval of the arc-shaped containing plates 12 is equal to the thickness of the weight blocks 3, and the arrangement interval refers to the distance between the upper plate surfaces of two adjacent arc-shaped containing plates 12. The arrangement interval can keep the plurality of weight blocks 3 in a vertically stacked and arranged state when being placed on the vehicle frame.

The front end of the arc-shaped containing plate 12 is conical or arc-shaped, so that the arc-shaped containing plate 12 and the arc-shaped containing hole 14 are more easily mutually inserted and matched when the heavy object block 3 is taken back to the containing frame 11.

The radius of the insert rod 10 is smaller than that of the insert hole 13, and the front end of the insert rod 10 is conical or arc-shaped, so that the insert hole 13 and the insert rod 10 are more easily inserted and matched with each other when the heavy object block 3 is taken back to the storage rack 11.

The weight blocks 3 are disc-shaped, and the shapes of the weight blocks 3 are the same. Because the frame can receive the vibration when carrying out the test, heavy object piece 3 is difficult to be in good vertical pile together when withdrawing, influences the use next time. Therefore, a vertical auxiliary positioning plate 15 is arranged on one side of the base 5, an arc-shaped groove 16 extending vertically is formed in the plate surface on one side of the auxiliary positioning plate 15, and the radius of the arc-shaped groove 16 is the same as that of the heavy object 3. After the heavy blocks 3 are retracted, the heavy blocks 3 are rotated toward the auxiliary positioning plate 15, and the heavy blocks 3 are vertically aligned again by means of the arc-shaped grooves 16. Since the weight blocks 3 are difficult to be perfectly vertically stacked when retracted, the radius of the insert pin 10 is set smaller than that of the insertion hole 13, also in order that the insert pin 10 can be inserted into the insertion hole 13 of each of the weight blocks 3 retracted when retracted.

The upright rod 6 is cylindrical, and the circle center of the arc-shaped containing plate 12 falls on the rotating axis of the lifting ring 7, so that the arc-shaped containing plate 12 can be more smoothly inserted into the arc-shaped containing hole 14.

The base 5 is composed of an upper first slide block 17 and a lower second slide block 18. The second sliding block 18 is in horizontal sliding fit with the test table board 1, and the first sliding block 17 is in horizontal sliding fit with the second sliding block 18; the sliding directions of the first sliding block 17 and the second sliding block 18 are perpendicular. As shown in the attached figure 1, the second sliding block 18 horizontally slides transversely, the first sliding block 17 horizontally slides longitudinally, and then the position of the heavy object on the test platform 1 is adjusted to adapt to different types of vehicle frames. The vertical rod 6 and the lifting cylinder 8 are both fixedly arranged on the first sliding block 17 and move along with the first sliding block 17.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
