Simple structure, reliability is high.All include mechanical accumulated energy and hydraulic energy-accumulating during each accumulation of energy simultaneously, double action can strengthen entirety
Energy storage effect.
On this basis further, mandrel component 1 is set to split-type structural, from top to bottom including top connection 11, flower
Key mandrel 12, compression spring mandrel 13 and lower mandrel 14, pass sequentially through threaded connection between two adjacent parts, form mandrel
The entirety of component 1.Preferably, as shown in Figures 2 to 4, the partial structurtes of the upper, middle and lower in Fig. 1 are represented respectively,
The upper end junction of each part sets internal thread, and lower end junction sets external screw thread, is cooperated by screw thread and is connected.
Top connection 11 and spline mandrel 12, spline mandrel 12 and compression spring mandrel 13, the company of compression spring mandrel 13 and lower mandrel 14
The appearance at the place of connecing to form step, and because one end size for setting internal thread is larger, therefore one end of setting internal thread is formed
Step.Top connection 11 only sets external screw thread in lower end, is provided for stopping the step of piston ring 4 on the surface of its column structure,
Piston ring 4 is set in top connection 11, and piston ring 4 relative with the generation of the appearance of top connection 11 can be slided.
Further, housing unit 2 is also configured as split-type structural, from top to bottom successively include joint 21, upper shell 22,
Lower house 23 and lower contact 24, aforementioned four part are fixed also by threaded connection.It is similar to mandrel component 1, in each component
The junction of lower end sets external screw thread, and the junction of upper end sets internal thread, unlike, the appearance of housing unit 2 is smooth, its
Inwardly projecting formation step at the external screw thread of lower end.The step for stopping piston ring 4, joint are formed with upper shell 22 on the bottom of joint 21
21 is tapered downwards with the junction of upper shell 22, wedge-shaped in cross-section, and the inwall that bottom protrudes from upper shell 22 forms step,
For against stop piston ring 4.Lower contact 24 is tapered upwards with the junction of lower house 23, wedge-shaped in cross-section, top ends with
Lower house 23 forms the step for stopping the bottom of compression spring 3.
Specifically, the top of compression spring 3 is formed by the appearance of compression spring mandrel 13 step and the inwall shape of lower house 23
Into step stop that two steps can stop spacing or compression to the top of compression spring 3 in different situations jointly.Pressure
The bottom of contracting spring 3 stops that two steps are in different situations jointly by the end of lower contact 24 and the end of lower mandrel 14
Spacing or compression can be stopped to the bottom of compression spring 3.
As shown in figure 5, being upper shell 22 and the cross-sectional view of the cooperation of spline mandrel 12.The inner side of upper shell 22 sets multiple
Keyway 221, sets multiple splines 121 for coordinating with the inserting of keyway 221, spline 121 and key on the outer wall of spline mandrel 12
Groove 221 cooperates can be with transmitting torque, the transmitting torque between mandrel component 1 and housing unit 2.The quantity of keyway 221 is big
In the quantity of spline 121, the keyway 221 not coordinated with spline 121 can be used for the compressed oil that circulates, make the motion of compressed oil more
It is smooth.
As shown in fig. 6, being compression spring mandrel 13 and the cross-sectional view of the cooperation of lower house 23.Hole on the inwall of lower house 23
The groove 231 of circulation compressed oil is provided at the minimum of footpath, the damping action of compressed oil can be effectively reduced, is easy to oiling.Groove
231 quantity can respective change as needed, these are all comprising within protection domain of the present utility model.
Because the lower end of compression spring 3 is threaded connection for spacing lower contact 24 and lower mandrel 14, can dismantle, because
This can change spring.By changing the compression spring 3 of different size specification, the same of enhancing (or reduction) mechanical accumulated energy is realized
When, reduce (or increase) hydraulic oil cumulative volume, and then increase (or reduction) hydraulic oil compression ratio, i.e., enhancing (or reduction) hydraulic pressure stores
Energy.Compression spring cumulative volume is bigger, and the acceleration effect of jar accelerator is stronger.
In any of the above-described technical scheme and its on the basis of being mutually combined, the external corners of mandrel component 1 and housing unit 2
Place is set to the chamfering between 60~80 degree, more specifically, chamfering is 70 degree.
The two-way accelerated mode of the bumper jar accelerator that the utility model is provided is realized by difference in areas：
Upward accelerator：By ground installation upper lifting pipe string, top connection 11 drives mandrel component 1 to move upwards, housing
Component 2 meets card pipe string by bumper jar and bottom or other act on pipe series winding and connect, and remains stationary as.Limit of the piston ring 4 in joint 21
Remained stationary as under the effect of position, the lower upward motion compresses hydraulic oil of mandrel 14 carries out hydraulic energy-accumulating.Receive lower casing in the upper end of compression spring 3
Body 23 is spacing, and lower end is pushed up by lower mandrel 14 to be compressed, and carries out mechanical accumulated energy.After after bumper jar release, hydraulic pressure and machinery
Accumulation of energy discharges simultaneously, significantly increases shock effect.
Downward accelerator：By pressure pipe string under ground installation, top connection 11 drives mandrel component 1 to move downward, housing
Component 2 meets card pipe string by bumper jar and bottom or other act on pipe series winding and connect, and remains stationary as.Piston ring 4 is in top connection 11
Moved downward under promotion, hydraulic fluid chamber reduces, moved downward with mandrel 14 at present, hydraulic fluid chamber increase.Because piston ring 4 cut
Area is more than the sectional area of lower mandrel 14, so generally, hydraulic oil is compressed, carries out hydraulic energy-accumulating.Receive down the lower end of compression spring 3
Joint 24 is spacing, and upper end is pushed down on by compression spring mandrel 13 to be compressed, and synchronously carries out mechanical accumulated energy.Treat that bumper jar discharges
Afterwards, hydraulic pressure and mechanical accumulated energy discharge simultaneously, significantly increase shock effect.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.Various modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice, can in other embodiments realize in the case where spirit or scope of the present utility model are not departed from.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
