Description

Apparatus of Seismic source Tagu}

The present invention relates to seismic surveying, which is a kind of physical exploration, and more particularly, to an automatic seismic source hitting device that is suitable for deep geological structure exploration by increasing seismic energy and suitable for operation in narrow farms and furnaces. will be.

In general, when an artificial force (shock) is applied to the ground (or rock) artificially, the ground vibrates and the vibration propagates in the underground strata medium in the form of a wave. This is called 'elastic wave' in academic terms. The seismic waves propagate in the underground strata, reflecting or refracting at the strata interface where the physical properties (density and seismic velocity) of the media are different.

In addition, an exploration device is required for the seismic field exploration, and the exploration device is largely composed of a seismic source, a seismic device (geophone or hydrophone), a recording device (seismograph), and the like.

Conventional acoustic wave generators are classified into explosive generators and non-explosive generators. Explosive sources cause seismic waves by explosive blasting such as dynamite, and waves have the advantage of impulse-type seismic characteristics, but require permission, professional handling technicians and blasting holes for each use. There are disadvantages such as problems. Non-explosive seismic sources are generally used as 'weight drop type' sources, which encompass all the seismic sources that use the point source of vertical single force at the surface. The simplest technique here is to drop a heavy object from high ground using the Earth's gravitational acceleration, or to double the acceleration of the object by springs or pneumatics.

Currently, most of the central fall type generators on the market are used on trucks or trailers because falling objects exceed 100 kg. These sources may be expensive purchase costs due to purchase, but above all, given the domestic geological and exploration conditions, domestic terrain conditions for seismic exploration are mostly narrow farms, mountainous and sloping terrain, and trucks or trailers. The use of acoustic wave generators mounted on the wall is fundamentally difficult.

Conventional technologies developed to cope with the above problems include the central fall-type source 'VAKIMPAX' developed by Prakla-Seismos, Germany. The generator is a cylindrical cylinder 100 having a hammer (not shown) having a weight of about 50 kg is inserted therein, a hydraulic pump 120 for lifting the hammer, and a wheel for moving the entire generator as shown in FIG. 1. It is composed of a self-engine 140 for driving the 180, a handle 160 for adjusting the direction when moving. The overall size is 2.6m in length, 1.1m in width and 1.2m in height with the cylinder cylinder 100 tilted to move the VAKIMPAK generating source.

In order to move the VAKIMPAK generation source of Prakla-Seismos, Germany, first, the cylindrical cylinder 100 is inclined, and then the wheels 180 are driven by using the engine 140 and the handle 160 is attached to the upper end of the generation source. The direction of the furnace is to be manipulated, and the clutch 200 for forward and reverse is also mounted. Position the source precisely at the shot point, lift the cylindrical cylinder 100 vertically, and lift the hammer (50kg) inserted therein through the winch operation driven by its own engine 140, and a simple clutch. (200) Free fall by operation. The lifting height of the hammer is about 1.6m.

Since the VAKIMPAK seismic source is about 50 kg in weight, the seismic energy radiated therefrom is somewhat different depending on the given exploration conditions. On the other hand, the existing sources of falling objects of more than 100kg are installed on trucks or trailers, so the high cost of purchasing will be a problem, but above all, given the geological and exploration conditions of the country (e.g. narrow farming and winding) In the light of the above, there is a problem that it is used in a very limited manner.

The present invention has been devised to solve the above problems, the purpose of which is the new generation source to identify the core (about depth 200 ~ 300m) stratum structure to make the weight of the hammer 150kg to greatly improve the seismic energy, It is to provide an automatic seismic generator source device that can adjust the overall size of the source to suit the domestic terrain conditions, and to be able to move and operate by its own engine.

The present invention is to achieve the above object is a cylindrical cylinder in which the hammer is inserted, the hydraulic cylinder that can adjust the angle of the cylindrical cylinder, the main frame, the main wheel and auxiliary wheels are installed, the engine, the hydraulic unit, a combination formed of a wire drum By providing a source device.

The operation of the present invention will be described with reference to the configuration as described above.

The cylinder center shaft 60 and the cylinder auxiliary shaft 64 are fixed to both ends of the main frame 58 in order to install the cylindrical cylinder 36 in which the hammer 38 is inserted in the upper center of the main frame 58. The engine 30, the hydraulic unit 22, and various operating units were disposed in consideration of the balance of the load around the main wheel 34.

The oilless bearing 40 is installed above and below the hammer 38, and the cylindrical cylinder 36 uses a honing pipe to minimize frictional resistance when the hammer 38 falls. Cylindrical cylinder 36 is installed on the top of the acceleration spring 72 to act as a buffer when lifting the hammer 38, and to accelerate when the hammer 38 falls to maximize the generation of the acoustic wave energy. In addition, by installing a gauge 42 to easily identify the lifting height of the hammer 38 in the center of the acceleration spring 72 so that the hammer 38 can always fall at a constant height to generate a constant seismic energy as possible To make it possible.

The wire 44 connected to the top of the hammer 38 is connected to the wire drum 56 through the roller 46 and operates the engine 30 and wires to the wire drum 56 using the wire drum clutch 16. By pulling the 44, the hammer 38 is lifted. On the contrary, in order to drop the hammer 38, the engine 30 is separated by the wire drum clutch 16 and the hammer starting lever 20 is operated. When the hammer 38 falls free, the impact plate 52 is impacted.

The striking plate 52 is attached with a trigger sensor 54 for transmitting a trigger signal to the measurement system. When the hammer 38 hits the cylinder holder 36 to be vertical to operate the horizontal lock handle 48 to lower the horizontal lock foot 68 to the ground.

When moving on inclined terrain or long-distance movement, by operating the hydraulic operation handle 24 of the hydraulic unit 22 to rotate the cylindrical cylinder 36 around the cylinder axis of rotation (62) so that it can be placed horizontally. 26 determines the flow of hydraulic pressure for raising or lowering the cylinder cylinder 36.

In addition, during movement, the hammer fixing wire 70 is connected to the bottom of the hammer 38 to fix the hammer 38, and is tightly tied to the hammer fixing ring 50.

The main wheel 34 used a tread tire to prevent slipping. Operation for movement of the source is possible by the accelerator 10, the left and right rotary clutch 12, the hand brake and the drive clutch 14, and the transmission gear lever 18.

By operating the hydraulic actuation handle 24, the hydraulic cylinder 28 is accelerated by setting the cylinder cylinder 36 vertically, separating the wire drum clutch 16 from the engine 30 power, and operating the hammer starting lever 20. It is a seismic wave generator source device which accelerates and falls the hammer 38 by the spring 72, and impacts underground.

In the case of the existing central drop type generators, in which most hammers weigh more than 100kg, they are mounted on large trailers or trucks, and therefore expensive purchase costs are also a problem. Esau's use is very limited.

Therefore, the features of the present invention are described below.

First, although the weight of the hammer is 150kg, the width of the whole source is only about 1.2m, so it can be freely operated in the domestic terrain.

Second, since the source of movement as well as various operating devices are possible by the power of its own engine, it is possible to operate the source with only one person.

Third, the 150kg hammer was dropped at 2.4m and accelerated to the falling object using the acceleration spring to maximize the seismic energy generated.

Fourth, maintenance is easy because all parts used in the present invention are configured to be procured in the country.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

This design uses 150kg hammer, which is much higher than the 50kg hammer used in the existing VAKIMPAK generator, and this hammer (150kg) has almost no friction inside the vertical cylinder (2.4m in height). Accelerated by strong springs mounted on the top of the cylinder at the same time as it falls, the seismic energy generated therefrom can be greatly improved, and unlike the existing sources mounted on large trailers or trucks, the overall size of this source is narrow. Designed to be convenient to move farms or lanes, it is suitable for domestic terrain conditions. On the other hand, it is possible to lift heavy hammer easily by winding strong wire connected to hammer with wire engine using its own engine, and by using hydraulic cylinder The angle can be adjusted from 0 ° to 90 ° and the source mobility can be driven by the engine It is a very useful design to improve productivity and work efficiency because only one person can easily move and operate the source.
