Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing embodiment of the present invention made into
One step ground describes in detail.
As it is shown in figure 1, be overall structure schematic diagram provided by the present invention, bumper jar/amortisseur is provided with along it axially extended
Cable transmission channel 5, cable transmission channel 5 runs through on the whole length direction of bumper jar/amortisseur, for transmitting the electricity of signal
Cable 4 is arranged in cable transmission channel 5；Cable transmission channel is the hollow chamber 7 of mandrel, and cable 4 is with straight line or spiral shell
Spiral form runs through the hollow chamber 7 of mandrel, as shown in Figure 12 and Figure 13.
In preferred technical scheme, bumper jar/amortisseur being additionally provided with disc spring pipe 3, disc spring pipe 3 is solid with mandrel 2
Fixed connection, and connect with cable transmission channel 5, cable 4 sequentially passes through cable transmission channel 5 and disc spring pipe 3.
Illustrate the cable 4 technical scheme by bumper jar/amortisseur separately below.
For the bumper jar/amortisseur of different structure, cable 4 along bumper jar/amortisseur axially through bumper jar/amortisseur
Scheme can choose one or both in following proposal.
Cable 4 arranges following four situation altogether by bumper jar/amortisseur:
A, cable 4 via structure: i.e. outer cylinder body 1 and or the wall of mandrel 2 on form radially and or axial hole,
Cable 4 passes in hole, as shown in Figure 2-5；
B, cable 4 cross sealing groove structure: form groove, groove on outer cylinder body 1 or the periphery of mandrel 2 or inner headed face
Inside there is cable 4, in groove, be filled with packing thing 6 or use overlaying method cable 4 sealing in groove, cable 4
It is embedded in the groove of outer cylinder body 1 or mandrel 2, as Figure 6-9.Packing thing 6 therein includes: solder, rubber, mould
Material, fluid sealant etc.；
C, cable 4 bundle outer cylinder body structure: be bundled with cable 4 in outer cylinder body 1 outer wall surface, outside cable 4
Sealing, sealing is had to cement in outer cylinder body 1 outer wall surface and cable 4 top.The most directly the cable 4 of transmission data is bundled
On outer cylinder body 1, cable 4 can be in the way of being straight line, as shown in Figure 10, it is also possible to is wrapped on outer cylinder body 1, such as figure
Shown in 11, then take adequate measures as with glue envelope, armouring etc., protected cable 4 without damage；
D, cable 4 cross mandrel hollow chamber 7 structure: cable 4 directly passes through the hollow chamber 7 of bumper jar/amortisseur,
Cable 4 can be in the way of being straight line, as shown in Figure 12 and Figure 13, it is also possible to is folding mode (as spiral), such as Figure 14
Shown in Figure 15, then take adequate measures as with glue envelope, armouring etc., protected cable 4 without damage.
Cable 4 use A, B, C mode through bumper jar/amortisseur time, cable 4 also need to also cross disc spring pipe 3,
Disc spring pipe 3 placement location and mode are as follows:
A, disc spring pipe 3 may be installed the top of mandrel, as being directly placed at outside mandrel 2 with the form of disc spring pipe
Dew position；
B, disc spring pipe 3 are directly placed in the hollow chamber 7 of bumper jar/amortisseur；
