Abstract

The utility model relates to a hypocenter for earthquake exploration, more particularly to a mechanical impact hammer including a hydraulic pump, a hydraulic cylinder, a spring, a lifting release hook, a hammer head, a chopping block and a guide pole; the hydraulic pump is connected with the hydraulic cylinder that is fixed on an upper cover plate, the upper cover plate is connected with a lower soleplate via the guide pole and is mounted with a release lever, the hydraulic cylinder is surrounded by the spring the upper end of which is connected with the upper cover plate and the lower end of which is connected with the hammer head, the top end of the hydraulic cylinder is connected with the upper end of the lifting release hook via the spring, the lower end of the lifting release hook is connected with the hammer head, the lower soleplate is outwards suspended with the chopping block. The work flow is as below: the hydraulic pump operates to lift the hydraulic cylinder, the hydraulic cylinder lifts the hammer head by lifting the release hook while compressing the spring on the hammer head to activate an activation key on the release hook to release the hammer head, the hammer head then activates the chopping block to create seismic waves. On account of creating the seismic waves mechanically, the explosive hypocenter can be replaced and safety of the construction is guaranteed, while no damage is applied to the environment and construction efficiency is enhanced.

Description

The physical shock hammer

Technical field

The utility model relates to the mechanical source that a kind of seismic prospecting industry is used, relate in particular to and a kind ofly hydraulic cylinder is promoted by hydraulic pump works, hydraulic cylinder promotes tup by promoting release hook, simultaneously with the length of spring compressed on the tup, excite the burst key that promotes on the release hook that tup is discharged by release lever, tup excites chopping block to produce the physical shock hammer of seismic wave.

Background technology

The focus kind of seismic prospecting industry is a lot, and the big easy to operate small-sized single-impact focus of excitation energy is rare.What routine was used is explosive or man-made explosion, and the explosive explosive source is dangerous, and the man-made explosion energy is little.Mechanical source safety, energy is big and efficient is high, is specially adapted to URBAN EARTHQUAKE exploration and shallow seismic exploration.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of safety, energy new mechanical ram hammer big, easy to use, with low cost are provided.

The utility model for achieving the above object, by the following technical solutions: a kind of physical shock hammer, it is characterized in that, it comprises hydraulic pump, hydraulic cylinder, spring, promote release hook, tup, chopping block, guide pillar, described hydraulic pump connects hydraulic cylinder by hydraulic oil pipe, hydraulic cylinder is fixed on the upper cover plate, handle is connected with upper cover plate, upper cover plate is connected with lower shoe by guide pillar and is fastening, guide pillar passes the pilot hole on the tup, upper cover plate is equipped with release lever, and hydraulic cylinder is surrounded with spring outward, and the spring upper end is connected with upper cover plate, the spring lower end is connected with tup, the hydraulic cylinder top is connected with the upper end that promotes release hook by spring, and the lower end that promotes release hook is connected with tup, and described chopping block is placed on the lower shoe bottom surface and contacts with ground.

The beneficial effects of the utility model: what routine was used is explosive or other non-explosive source, and the explosive explosive source is dangerous, and other non-explosive source energy is little.This physical shock hammer is safe in utilization, energy is big and efficient is high, is specially adapted to URBAN EARTHQUAKE exploration and shallow seismic exploration.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, a kind of physical shock hammer, be characterized in, it comprises hydraulic pump 16, hydraulic oil pipe 14, hydraulic cylinder 1, spring 3, promote release hook 4, tup 5, chopping block 7, guide pillar 9, connect hydraulic cylinder 1 by external hydraulic pump by hydraulic oil pipe, hydraulic cylinder 1 is fixed on the upper cover plate 11, handle 10 is connected with upper cover plate 11, upper cover plate 11 is connected with lower shoe 13 by guide pillar 9 and is fastening, guide pillar 9 passes the pilot hole 15 on the tup 5, and tup 5 slides on guide pillar 9, and upper cover plate 11 is equipped with release lever 2, the hydraulic cylinder 1 outer spring 3 that is surrounded with, spring 3 upper ends are connected with upper cover plate 11, and spring 3 lower ends are connected with tup 5, and hydraulic cylinder 1 top is connected with the upper end that promotes release hook 4 by spring 3, the lower end that promotes release hook 4 is connected with tup 5, and described chopping block 7 is placed on lower shoe 13 bottom surfaces and contacts with ground.Described guide pillar 9 is equipped with outer cover 12, and outer cover 12 places on the lower shoe 13, is connected with trailing wheel 8 with front-wheel 6 respectively before the lower shoe 13.

Principle of work: primer fluid press pump 16 work, by hydraulic oil pipe 14 hydraulic cylinder 1 is promoted, hydraulic cylinder 1 promotes tup 5 by promoting release hook 4, simultaneously with 3 compressions of the spring on the tup 5, after reaching the pressure of regulation, the work of stop solution press pump discharges tup 5 by making release lever 2 open release hook 4, and tup 5 moves downward under the positioning action of guide pillar 9 and impacts chopping block 7 generation high frequency artificially seismic waves.

The utility model is through the seismic prospecting site test, hypocentrum cartridge spectrogram 2 and with compressional wave spectrogram of the present utility model 3 contrasts, Fig. 3 has wideer motivated frequency bands and abundanter stimulating frequency than Fig. 2, conventional buckle spectrogram 4 is compared with shear wave spectrogram 5 of the present utility model, compare its hypocentrum cartridge Fig. 5 and conventional buckle focus spectrogram 4, wideer with the physical shock hammer as the utility model spectral range of focus, more be applicable to the exploration of shallow-layer high-frequency seism.By shown in Figure 6, hammer the single-shot record into shape with physical shock and have identical energy effect with 3 folded records that hang down, and stable, good reproducibility.

The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
