Embodiment 6
As shown in Figure 3, internal layer double wedge 91 corresponding to each group job module has equally distributed two at the outer surface of axis 92, outer double wedge 93 has equally distributed two at the inwall of shell 94, be each group job module respectively to a pair of internal layer double wedge 91 and pair of outer layer double wedge 93 should be arranged, a pair of internal layer double wedge 91 and pair of outer layer double wedge 93 totally 4 double wedges all be positioned at axis 92 axle center along axis 92 straight line radially---on the double wedge line 11 of this group job module.
In order to guarantee slow continuity and stability of falling operation, at any time should keep more group operation module to participate in exhaust operation, less group operation module as far as possible and participate in ventilation and reset that to rotate rhythm even for operation and operation; This can keep take central axis 1 as the axle center by the double wedge line 11 of adjacent operation module (the operation module of establishing two ends also is adjacent block) with angle misplace in turn and the dislocation angle sum of the double wedge line 11 of all adjacent operation modules is π (rad), and the maximum center of circle angle that the relative sliding in cylinder 101 experiences during 102 exhaust of appropriate design exhaust pition realizes; Fig. 4 is the Pareto diagram of the double wedge line 11 of each operation module (having ten group job modules), take central axis 1 as the axle center, pass through and be respectively the double wedge line 1101 of the first group job module, the double wedge line 1102 of the second group job module, the double wedge line 1103 of the 3rd group job module, the double wedge line 1104 of the 4th group job module, the double wedge line 1105 of the 5th group job module, the double wedge line 1106 of the 6th group job module, the double wedge line 1107 of the 7th group job module, the double wedge line 1108 of the 8th group job module, the double wedge line 1109 of the 9th group job module, the double wedge line 1110 of the tenth group job module, the double wedge line 11 of adjacent operation module keeps
The in turn dislocation of angle.
Operation module group number is no less than 8 groups; The accuracy of manufacture at descending lifeline satisfies under the prerequisite of descending lifeline corresponding component normal operation, cylinder 101, the size of annular connecting rod 103 and connecting rod guide rail 1031 and angle design should make exhaust pition 102 take turns in the exhaust one and get large value with the radian of cylinder 101 inwalls generation relative sliding as far as possible, but less than π (rad), only have at most with regard to guaranteeing to keep at any time as much as possible the group job module to be in the exhaust operation like this and lack the group job module as far as possible and be in the operation that resets, namely just begin or during the intermittent conversion of operation module job state slow falling, the pressure of uprushing by the many group jobs module that is in the exhaust operation with the certain proportion shared, weakening thus the cylinder 101 interior gas compressions that cause because of the pressure of uprushing affects the pulsed that the tumbler rotating speed produces, with only have 2 group job modules and compare, more operation module group number can obviously weaken tacho-pulse formula fluctuating range and increase the frequency of tacho-pulse formula fluctuation, and tumbler can be rendered as satisfied relative uniform rotation state when more and all cylinder 101 cross section of inboard wall area summations were larger when operation module group number.Provide at last following data analysis:
Suppose that descending lifeline has 10 group job modules, and get for simplification in calculating and whenever have 9 group job module exhausts, 1 group job module to reset; Cylinder 101 cross section of inboard wall area summations equal 200 square centimeters, and the bearing capacity that descending lifeline delays when falling is that 100 kgfs and this bearing capacity put on cylinder 101 interior gases through conduction unchangeably by exhaust pition 102 sizes.
If slow fall the pressure of uprushing when just beginning and cause first compressed cylinder 101 interior gases to be compressed into the m of cylinder 101 maximum volumes
*/ 9.Then have
Solve m
*The boundary has 7 cylinders 101 compressed between 3 and 2 when stress equalization is described.The radius of turn of supposing exhaust pition 102 mid points is 13 centimetres, then is to the maximum at the slow linear distance (descending with the distance of 2 busts) that falls piston mid point process when just beginning to uprush pressure
Centimetre.This bust distance can not damage human body, yet can not cause huge impulse force and make it damage descending lifeline.
The pressure jump that the intermittent job state conversion of operation module also can make the cylinder 101 interior gases that respectively are in the exhaust operation be subject to makes originally to be in exhaust condition and to continue 8 cylinders 101 of exhaust and 1 new cylinder 101 that adds exhaust pressure of uprushing altogether
Newton, total pressure-bearing is increased to 2800 newton by 2689 original newton.If uprush each cylinder 101 interior gas volume that pressure causes being in the exhaust operation of reason are reduced the e/9 of cylinder 101 maximum volumes thus, then can be according to following Formula For Solving e:
Can solve e=0.1983, illustrate that the distance that descends with 2 busts is no more than
Centimetre, can ignore on the impact of uniform descent.
The technical scheme of present embodiment is applicable to the descending lifeline of above-mentioned arbitrary embodiment.
