[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The utility model provides Figure 1-4 The equipment inspection test bench shown in the figure comprises a mounting plate 1 and a mounting frame 4. The mounting plates 1 are welded at both ends of the bottom of the mounting frame 4, and the mounting frame 4 is fixed at the mounting position by two mounting plates 1 and a plurality of bolts. A vibration frame 5 is arranged on the upper side of the mounting frame 4, and the two frames are parallel to each other. The four corners of the mounting frame 4 and the vibration frame 5 are connected with load-bearing springs 6. The top of the vibration frame 5 is welded with a vibration table 7. When installing and using the equipment inspection vibration test bench, it is necessary to first determine the installation position of the equipment inspection vibration test bench, and then use a crane to lift the mounting frame 5. The frame 4 is placed at the position where it needs to be used, and then the mounting plates 1 at both ends of the frame 4 are firmly fixed at the position by multiple bolts. Then the vibration frame 5 needs to be lifted by a crane and moved to the parallel upper side of the frame 4, and then the load-bearing springs 6 are welded to the spring connecting blocks A2 at the four corners of the upper end of the frame 4, and then the vibration frame 5 is slowly moved down by the crane, so that the spring connecting blocks B3 at the four corners of the bottom of the vibration frame 5 are respectively in contact with the upper ends of the four load-bearing springs 6, and then the top of the load-bearing spring 6 is welded to the spring connecting block B3 by welding.
[0020] like Figure 1 and Figure 3 As shown, an electric vibrator 9 is arranged at the bottom center of the vibration table 7. The electric vibrator 9 uses a vibration motor as a vibration source to generate vibration. Then, the electric vibrator 9 at the bottom of the vibration table 7 is connected to a power supply with a controller through an electric wire. Then, the equipment to be inspected is placed on the vibration table 7, and the equipment is protected by a lifting protection device 8. Then, the electric vibrator 9 is started to carry out the vibration experiment.
[0021] like Figure 1 and Figure 4As shown, a lifting protection device 8 is arranged on the outside of the vibration table 7, and the lifting protection device 8 includes a tightening screw hole 10, a tightening screw rod 13, a lifting slide groove 14 and a metal protective cover 15. The metal protective cover 15 is sleeved on the outside of the vibration table 7. Lifting slide grooves 14 are vertically arranged inside both ends of the metal protective cover 15, and tightening screw rods 13 are penetrated outwardly inside the two lifting slide grooves 14. Tightening screw holes 10 are arranged inside the center of both ends of the vibration table 7, and the inner ends of the two tightening screws 13 are respectively inserted into the inside of the two tightening screw holes 10. When the height of the equipment to be inspected is relatively high, the equipment is placed on the vibration table 7 for vibration testing. Therefore, it is necessary to increase the protection height of the lifting protection device 8 so that it can fully and conveniently protect the equipment. When adjusting, it is necessary to rotate the two tightening screws 13 counterclockwise by operating the knob 11 so that the two tightening screws 13 are respectively lifted from the vibration table. 7, withdraw from the tightening screw holes 10 at both ends of 7 until the two positioning and pressing rings 12 are respectively changed from the state of tightly pressing against the outer walls of the two ends of the metal protective cover 15 to the disengaged state, which will unlock the metal protective cover 15, and then you need to use your palm to drag the bottom of the metal protective cover 15 and push it upward to increase the protective height of the metal protective cover 15 on the upper end of the vibration table 7 until it can effectively protect the equipment, and then maintain this height and drive the two tightening screws 13 to rotate clockwise through the operating knob 11, and the two tightening screws 13 will slowly penetrate into the tightening screw holes 10 through the thread pushing action until the two positioning and pressing rings 12 are respectively tightly pressed against the outer walls of the metal protective cover 15, and the metal protective cover 15 is fixed in height by pressing against and increasing friction, so that the metal protective cover 15 can rise to a higher height and protect the equipment.
[0022] like Figure 1 and Figure 4 As shown, the lifting protection device 8 also includes an operating knob 11 and a positioning and clamping ring 12. Two operating knobs 11 are provided, and the two operating knobs 11 are respectively fixed at the outermost ends of the two tightening screws 13. Positioning and clamping rings 12 are welded on the inner sides of the two operating knobs 11 and on the outsides of the two tightening screws 13.

The four spring connecting blocks A2 and the four spring connecting blocks B3 are connected with load-bearing springs 6 by welding. The load-bearing springs 6 can not only fix the vibration frame 5 on the parallel upper side of the mounting frame 4, but also play the role of vibration amplification when the electric vibrator 9 is working.
[0024] like Figure 1 and Figure 2 As shown, the length, width and thickness of the placing frame 4 and the vibration frame 5 are respectively the same, the placing frame 4 and the vibration frame 5 are both solid metal frames, the diameters of the spring connecting block A2 and the spring connecting block B3 are equal, and the placing frame 4 and the vibration frame 5 of the solid metal frame can not only increase their own strength, but also withstand a larger vibration amplitude, and can also avoid deformation from occurring easily.
