Abstract
The utility model discloses a cylinder type vibroseis vibrator. The center of a hammer body is provided with a round hole; an upper copper bush and a lower copper bush are in interference fit at the upper part and the lower part of the round hole of the hammer body, and are pressed tightly and fixed by a screw cover, a sealing piece and a fastening piece; the hammer body, the upper copper bush and the lower copper bush are internally and respectively provided with oil ducts which are communicated mutually; an cylinder bush is arranged on the inner wall in the round hole of the hammer body between the upper copper bush and the lower copper bush; the round hole at the position is internally matched with a piston, and is divided into an upper oil chamber and a lower oil chamber by the piston; and a piston rod of the piston is a reducing type piston rod with thin upper piston rod and thick piston rod. In the utility model, the reducing type piston rod structure is adopted, therefore, the piston action area of the lower oil chamber is larger than that of the upper oil chamber; and under the condition of same movement speed of the hammer, as the piston action area of the lower oil chamber is small, the flow rate of hydraulic oil entering the lower oil chamber is reduced, thus reducing the volume of the whole work cylinder, and lowering the requirement on oil supply amount of a hydraulic pump. The cylinder type vibroseis vibrator improves the natural frequency, and is beneficial to the improvement of vibrating performance.
Description
One, technical field
The utility model relates to a kind of oil seismic exploration device, relates in particular to a kind of vibroseis Vib..
Two, background technology
At present, the vibroseis Vib. is traditional piston type, mainly is made up of hammer body, piston, copper sheathing, gland, seal and securing member.Hammer body is a rectangle steel block, and there is a circular hole at the center; Piston and piston rod are cylindrical, and piston diameter equates with the steel bushing internal diameter of hammer body inside and greater than diameter of piston rod; Copper sheathing is a hollow cylinder, and internal diameter equates that with diameter of piston rod oil duct is arranged on the copper sheathing.Hammer body, piston and piston rod thereof and copper sheathing are in conjunction with forming the hollow cylinder working oil chamber: upper oil cavitie and lower oil cavitie; Have oil duct on the hammer body, be connected mutually with oil duct on the copper sheathing.Piston rod is one to maintain static part.During work, external control valve control hydraulic oil enters working oil chamber by oil duct, as upper oil cavitie, the acting force of hydraulic oil will act on above the piston and the copper sheathing lower surface simultaneously, motionless because of piston rod, under the effect of power, copper sheathing drives hammer body by gland and moves upward, lower oil cavitie is diminished, fluid is wherein discharged by oil duct, otherwise hydraulic oil enters lower oil cavitie, hammer body will move downward, and the fluid of last oil duct is discharged by oil duct.Usually vibroseis drives the hammer body motion by a constant-pressure variable hydraulic pump, and the to-and-fro movement that can produce different frequency by control system control, because the control features of control system, when the low frequency of hammer body and high frequency motion, need hydraulic pump to provide very large fuel delivery to satisfy the requirement of hammer body motion, therefore, the fuel delivery to hydraulic pump requires to increase.Moreover its oil duct volume is big, and Vib. is reduced admittedly frequently, is unfavorable for that the vibrations performance of Vib. improves.
Three, summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, and a kind of volume that reduces working oil chamber is provided, thereby reduces the fuel delivery of hydraulic pump, improves the cylinder type vibroseis Vib. of Vib. vibrations performance.
For finishing above-mentioned purpose, technical solution of the present utility model is: a kind of cylinder type vibroseis Vib., and it comprises hammer body, piston, upper and lower copper sheathing, gland, seal and securing member; There is a circular hole at the hammer body center, and upper and lower copper sheathing is interference fitted in the upper and lower of hammer body circular hole, and is fixed by gland, seal and securing member, has the oil duct that interconnects in hammer body and the upper and lower copper sheathing; On the hammer body circular-hole internal-wall between the upper and lower copper sheathing oil cylinder cover is arranged, be combined with piston in the circular hole at this place, be divided into upper and lower oil pocket by piston, the piston rod of piston is the reducing type piston rod that upper piston rod is thin, lower piston rod is thick, and itself and oscillating flat plate are rigidly connected.
The utility model has adopted the piston rod construction that becomes diameter, the diameter of piston-rod lower end is big than the upper end, make that like this lower oil cavitie piston action area is bigger than upper oil cavitie, when hammer body because the effect of pressure oil when moving back and forth, under the identical situation of movement velocity, because the active area of lower oil cavitie piston is little, the flow that enters into lower oil cavitie hydraulic oil reduces, thereby reduced the volume of whole operating cylinder, to the fuel delivery requirement reduction of hydraulic pump.Moreover the solid frequency that it has improved Vib. helps the raising of the vibrations performance of Vib..
Four, description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is with structural representation of the present utility model.
Five, embodiment
As shown in Figure 1, present embodiment comprises hammer body 5, piston 9, upper and lower copper sheathing 6,12, gland 3, O-ring seal 2 and fastening bolt 1.There is a circular hole at hammer body 5 centers, and upper and lower copper sheathing 6,12 is interference fitted in the upper and lower of hammer body circular hole, and are fixed by gland 3, O-ring seal 2 and fastening bolt 1.Have the oil duct 7,8 that interconnects in hammer body 5 and the last copper sheathing 6, have the oil duct 10,11 that interconnects in hammer body 5 and the last copper sheathing 12.Oil cylinder cover 15 is arranged on the hammer body circular-hole internal-wall between the upper and lower copper sheathing 6,12, be combined with piston 9 in the circular hole at this place, be divided into upper and lower oil pocket 16,17 by piston 9.The reducing type piston rod that the piston rod of piston 9 is that upper piston rod 4 is thin, lower piston rod 13 is thick, itself and oscillating flat plate 14 are rigidly connected.
