The specific embodiment
Telescoping ram of the present utility model is made up of two parts: balance pipe nipple and transmission backup pipe nipple
The balance pipe nipple comprises high pressure sealing shown in Figure 21, dummy piston 4 shown in Figure 3,68 core joint assemblies 30 shown in Figure 4 successively shown in Fig. 2-4.
The backup pipe nipple comprises direct current generator shown in Figure 4 10, power transmitting mechanism shown in Figure 5, thrust transmission mechanism shown in Figure 6 successively shown in Fig. 4-7, and six arms shown in Fig. 7.
Can divide by Rapid-turning nut 6 rotation these two parts are separated fast, be convenient to maintenance.In the prior art, the balance pipe nipple is arranged on transmission backup pipe nipple bottom, and in the utility model, the balance pipe nipple is arranged on topmost.
As Fig. 1 and shown in Figure 7, each arm includes main arm rest 23, assembly 34, auxiliary 32.Six armlets evenly distribute along circumference around main matrix 25.
The operating principle of balance pipe nipple is such: the left side of the dummy piston 4 shown in Fig. 3 is equilibrium oils 43, and the right contacts with extraneous pit shaft mud oar liquid 34, by moving of piston. the pressure that guarantees the instrument internal equilibrium oil is identical with extraneous pit shaft mud oar hydraulic coupling.
As shown in Figure 2, different with 67 core sealing plugs of prior art, what the present invention adopted is 68 core high pressure sealing plugs.Each pin diameter of 67 core plugs is little, is easy to damage, and does not have central tool bore simultaneously, is unfavorable for installation and removal.68 core plugs have increased a threaded installing hole in center, are used for installation and removal and use.
As Fig. 4, shown in Figure 5, pressure-bearing motor casing 9 inside are equipped with dc motor 10, and the output of direct current generator 10 connects power transmission shaft 11.The utility model also is provided with button distance limiter 12, is used to protect motor.Be connected with connecting axle 13 in turn, self-locking device 14, ball screw 31 after the button distance limiter 12.
When the dc motor 10 that is installed in pressure-bearing motor casing 9 inside is rotated in the forward, motor drives power transmission shaft 11 rotates, power transmission shaft 11 ratchet knobs are apart from the input left end of limiter 12, make its rotation, driving connecting axle 13 rotates, connecting axle 13 rotates the input of self-locking device 14, and the output of self-locking device 14 drives ball screw 31 and rotatablely moves, and ball screw nut 15 is made straight ahead.Ball screw nut 15 drives distance rod 16 and thrust disc 17 straight ahead.Thrust disc 17 promotes transmission distance rod 19 and does rectilinear motion by pushing away disk spring 18.Sealing distance rod 20 is to be threaded with distance rod 19, thereby also does rectilinear motion.
Sealing distance rod 20 is connected with connecting rod 21.Connecting rod 21 promotes principal arms and connects pins 24, and wherein principal arm connects pin 24 and promotes mainly arm rest 23 and is assembled into integral body by hold-down screw 22.In addition, principal arm connects pin 24 and promotes mainly arm rest 23 and also can form a global facility by hold-down screw 22.Promoting mainly arm rest 23 is connected with main matrix by main connecting pin 29, motion along with connecting rod 21, promoting mainly arm rest 23 opens around being rotated counterclockwise, along with promoting mainly opening of arm rest 23, drive auxiliary 32 and 34 motions of electrode pad assembly, open together,, can control the opening angle of promoting mainly arm rest 23 by the motion of control dc motor 10.
Sealing distance rod 20 band connecting rods 21 rectilinear motions, band is promoted mainly arm rest 23 and is rotatablely moved, and T RunddichtringO 28 is guaranteed distance rod 20 and main matrix 25 sealings, prevents that interior oil from spilling.
The benefit of this structure is that connecting rod 21 is very short, just can realize opening of backup arm 23.Traditional mode is to increase fulcrum at the middle part of promoting mainly arm rest 23, and the present invention has fulcrum at the left end of promoting mainly arm rest 23, and benefit is when promoting mainly arm rest 23 and be in various opening angle, electrode pad assembly 34 stressed more even.
If motor reverse rotation, ball screw nut 15 are done rectilinear motion towards a left side, promote mainly the pulling force that arm rest 23 is subjected to connecting rod 21, turn clockwise around main matrix 25 by main connecting pin 29, promote mainly that arm rest 23 drives electrode pad assemblies 34 and auxiliary 32 draws in.
As shown in Figure 4,68 core joint assemblies 30 of the present utility model have feather key, and have keyway on pressure-bearing motor casing 9 and the housing joint welding assembly 7, the two connects by two companies fixedly connected pin, compression spring 8 can be regulated the length of fit of the two, when housing joint welding assembly 7 is installed, compresses 68 core joint assemblies 30, thereby guaranteed that 68 core joint assemblies 30 and housing joint weld locating automatically accurately of assembly 7, installed to be very easy to.
Similar, being connected all between interconnecting tube 2 and fixing seal head 5 and the balance shell 3 by the keyway location, thus guaranteed 68 core high pressure sealing plugs 1 and the accurate location of promoting mainly arm rest 23.
On the main matrix 25 along six step troughs of radial distribution.The big coupling head 33 of annular is enclosed within on the above-mentioned step trough of main matrix 25.Big coupling head 33 connects and main matrix 25 adopts split typely, is convenient to processing, welding at last, and Pei Zhi advantage is that this structure processes easily like this.
Be installed in the utmost point seal nipple 37 of electrode pad 34, connect lead 38 and pass by the side trough of promoting mainly arm rest 23, enter instrument internal by seal nipple 35 connections that are installed in big coupling head 33 again, the instrument wiring is very simple.
During operational maintenance, the line that only needs to change between utmost point seal nipple 37 and seal nipple 35 gets final product.Traditional mode is welded cabling between assembly 7 outsides and the insulation crust 36 at the housing joint of instrument, and the instrument maintenance is very complicated.Characteristics of the present utility model are to promote mainly the side fluting wiring of arm rest 23 simultaneously.
In addition, the utility model also is provided with protection connection cover 40, and above-mentioned protection connection cover is circular-arc, and screwed hole is set on the connection cover,, when changing sealing ring 28, connection cover 40 is dismantled on main matrix 25 by screw.Therefore, replacing T RunddichtringO 28 is more convenient.
Maximum characteristics of the present utility model are to adopt split processing welded structure, center tap 41 and metal shell 42 processed respectively, and then in integral solder, i.e. housing joint welding assembly 7.
