Problems solved by technology

Similarly, the output level of the shear wave vibrator is positively correlated with the size of the vibrator assembly, and due to the limitation of the space structure of the frame, the design of the shear wave vibrator assembly is more compact and more complicated.

Embodiment Construction

[0033] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the descriptions of the embodiments or the prior art. Obviously, the accompanying drawings in the following description are only of the present invention. For some embodiments, those of ordinary skill in the art can also obtain other drawings based on these drawings without paying creative efforts.

[0034] Such as Figure 1-12 As shown, a vibrator assembly with a centering structure includes a plate assembly and a weight assembly. The hammer body 8 of the weight assembly is connected to the plate assembly by means of elastic connectors. The weight The two ends of the piston rod 6 of the hammer assembly are respectively fixedly connected with the plate assembly by means of the end cap 7; the elastic connector includes a centering spring 3, a centering spring seat 4 and a centering ...

Abstract

The invention provides a vibrator assembly of a centering structure, which comprises a flat plate assembly and a heavy hammer assembly, a hammer body of the heavy hammer assembly is connected with the flat plate assembly through an elastic connecting piece, and the two ends of a piston rod of the heavy hammer assembly are fixedly connected with the flat plate assembly through end covers; the elastic connecting piece comprises a centering spring, a centering spring seat and a centering spring seat limiting seat, a centering spring mounting hole is formed in the hammer body, and the centering spring is in close fit with the centering spring mounting hole of the hammer body through tolerance fit. Due to the closed box type structural design, the vibrator assembly has high torsion resistance and sufficient rigidity, the overall performance of the vibrator assembly is more stable, meanwhile, space is saved, the length and width of the whole vehicle are greatly reduced, and the vibrator assembly is beneficial to exploration in cities and towns. The mechanical structure is more stable and firmer, and compared with an air bag, the wear resistance is longer, and the service life is longer.

Description

technical field [0001] The invention belongs to the technical field of shallow geophysical exploration, and in particular relates to a vibrator assembly with a centering structure of a small tonnage shear wave vibrator. Background technique [0002] The longitudinal wave vibroseis (the hammer body vibrates in the vertical direction) has been widely recognized and realized large-scale application in the field of seismic exploration. Compared with longitudinal wave vibration, shear wave vibration has low wave velocity and short wavelength. Generally speaking, shear wave vibroseis is used in shallow shear wave seismic exploration and urban exploration, which can find out the location of shallow faults and divide different engineering geology on the section. Zoning provides reliable geological basis for urban earthquake-proof planning, earthquake safety evaluation, construction site selection, and foundation treatment. Similarly, the output level of the shear wave vibrator is p...
