Detailed description of the invention
Particular content of the present utility model is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, well head simple adjusting device, comprise: the apparatus body 1 that well head needs are fixing and square frame 2, need fixing apparatus body 1 is provided with flange 3 at described well head, described flange 3 is evenly provided with four Flange joint seats 4, four angles of described square frame 2 are respectively arranged with four frame Connection Blocks 5, and described Flange joint seat 4 is connected with frame Connection Block 5 respectively by adjusting device 6, the structure of described adjusting device 6 comprises: rotate adjustable pipe 7, the middle part of described rotation adjustable pipe 7 is provided with central rotation hole 8, adjusting nut 9 is respectively arranged with at the two ends of described rotation adjustable pipe 7, the threaded screw rod 10 cooperatively interacted with adjusting nut 9 is respectively arranged with at the two ends of described rotation adjustable pipe 7, in the end of described threaded screw rod 10, threaded screw rod brace 11 is set, described threaded screw rod brace 11 is provided with connecting hole 12, threaded screw rod 10 between described threaded screw rod brace 11 and adjusting nut 9 is arranged with locking nut 13 and nut check handle 14, described two threaded screw rod braces 11 are connected with frame Connection Block 5 with Flange joint seat 4 with attachment screw 15 respectively by connecting hole 12.
First to select the rotation adjustable pipe 7 within the scope of it when well head simple adjusting device uses according to space length, ensure that two ends threaded screw rod can meet job requirements after screwing out; The adjusting nut 9 rotating adjustable pipe 7 two ends adopts dextrorotation adjusting nut and left-handed adjusting nut, and adjusting nut 9 is welded as a whole with rotation adjustable pipe 7.Symmetrical single adjustment of must not regulate is answered during adjustment, insert in central rotation hole 8 with special tool during adjustment, firmly pull rotation adjustable pipe 7 to rotate, if be rotated counterclockwise because two ends thread rotary orientation is inconsistent so leading screw is simultaneously protruding, otherwise the then two ends leading screw that turns clockwise inwardly shrinks simultaneously, when reaching locked position, be locked by locking nut 13 and nut check handle 14.Because symmetry regulates wellhead component to be easy to centering, provide conveniently to assembly and disassembly, improve safety factor and operating efficiency.
Above-mentioned well head simple adjusting device, overhaul for the ease of well head assembly and disassembly, structure design adopts movable rotation regulative mode, rotate adjustable pipe, stretch or contract apart from the stroke for double pitch, have the function that two pitch airscrew stretches, regulates, locks, fixes, reach province's merit, laborsaving, timesaving effect, volume is little, lightweight, flexible to operation.
