Background
Vibration exciters are devices attached to certain machines and equipment to generate excitation forces, and are important components that utilize mechanical vibrations. The vibration exciter can enable the excited object to obtain a certain form and size of vibration quantity, so that vibration and strength tests are carried out on the object, or calibration is carried out on a vibration testing instrument and a sensor. The vibration exciter can also be used as an excitation component to form a vibrating machine for realizing the work of conveying materials or objects, screening, compacting, forming, tamping soil sand and stone and the like. At present, two placing modes of the vibration exciter exist, one is placed on a fixed tabletop or the ground, and the other is to hang the vibration exciter by adopting a pulley mechanism. When the dynamic characteristics of the pipeline system are tested, because the structure of the pipeline is complex, the vibration exciter needs to be adjusted up and down, meanwhile, the angle of the vibration exciter also needs to be adjusted, the pipeline system is small in space, and the traditional desktop or ground placed vibration exciter cannot meet the position requirement of the pipeline dynamic test. In addition, it is difficult to finely adjust the vertical position of the exciter by using a mechanism such as a pulley. The suspended vibration exciter is easy to shake, so that the pipeline bears extra load. As disclosed in chinese patent publication No. CN115654285A, a vibration exciter mounting device is disclosed, which drives a lifting platform to perform height adjustment by a driving cylinder, so that objects with different heights can be tested, however, the impact force of the driving cylinder is larger, and it is difficult to fine tune the up-down position of the vibration exciter, so that it is necessary to provide a vibration exciter mounting device with compact structure, which realizes fine tuning of the vibration exciter, and meets the requirements of fixing different depths.
