Cementing head is Cementing specific purpose tool, is connected by landing joint with bunch tube or drilling rod during well cementation, for defeated
Cementing fluid is sent to underground precalculated position.For cementing head as connection underground and the hinge of ground installation, being can not in cementing operation
Or scarce key equipment.For control device cost, on the premise of normal construction is ensured, oil field generally uses both at home and abroad at present
Straight-bar pin-blocking type cementing head, straight-bar pin-blocking type cementing head are to change the shape residing for plug using the contact relation of backing pin and plug
State.Backing pin vertically passes in and out cementing head body by the rotation of handwheel, because plug is in cementing head body interior, is rotating handwheel
When, whether technical staff by hand tentatively to perceive plug descending if can only touching cementing head lower end, however, at the scene noise it is excessive,
In the case that cementing head body is thicker, it can not accurately conclude whether plug is descending.
It is not in place in backing pin opening, when plug is stuck in cementing head by backing pin and fails pressure, it can have a strong impact on that well cementation is applied
Work causes to stay cement plug accident, once staying plug accident, oil well will be caused not go into operation normally, and the later stage bores plug well workover
Somewhat expensive.Therefore, the cementing cement head for designing a kind of simple rubber plug indicator of band is particularly important.In existing band rubber plug indicator
Cementing head in, have the cementing head of mechanical rubber plug indicator and magnetic induction rubber plug indicator, mechanical rubber plug indicator cement
Head is to judge that plug passes through situation by thrust bearing and pointer combination；Magnetic induction rubber plug indicator cementing head then needs
It is equipped with special magnet plug and secondary meter passes through situation to detect plug.While the existing cementing head with rubber plug indicator is also
There is the drawbacks such as complicated, difficulty of processing is big, operation inconvenience, maintenance difficulty.
Utility model content

Between cavity in be placed with plug, in the middle part of cementing head body outside be installed with the horizontal silk communicated with cementing head body
Thick stick housing, horizontal screw lead is provided with horizontal screw lead housing, and one end of horizontal screw lead is connected with what is be integrally formed with horizontal screw lead
Backing pin, the horizontal screw lead other end is provided with the handwheel positioned at flat leading screw hull outside, in horizontal screw lead housing side square crossing
Vertical leading screw housing is fixed with, vertical leading screw housing penetrates with horizontal screw lead housing junction, is provided with vertical leading screw housing perpendicular
Raw silk rings thick stick, vertical leading screw middle and upper part are carved with calibration loop, can be intermeshed between vertical leading screw and horizontal screw lead.
The horizontal screw lead housing for gate valve for slurry in 45 ° with being staggered.
When the backing pin retreats to cementing head inner body wall outside completely, the calibration loop on vertical leading screw is just exposed at perpendicular completely
Raw silk rings thick stick housing tip.
The backing pin is provided with sealing gasket with horizontal screw lead transition position.
The plug maximum outside diameter is slightly less than cavity internal diameter.
The beneficial effects of the utility model are：On the basis of existing straight-bar pin-blocking type cementing head, with reference to horizontal screw thread with
The worm gear auxiliary structure of vertical screw thread composition, overcome existing rubber plug indicator labyrinth and add-on device to cementing head sheet
The defects of body strength reduction, on no operating habit for changing original well head operating personnel, by observing on vertical leading screw
Calibration loop can just judge whether backing pin is outer easily and fall back on position, avoid and move back the possibility descending less than position influence plug outside backing pin,
The cementing head is simple in construction simultaneously, and processing and manufacturing cost is low, good seal performance, easy maintenance, safe and reliable and can be suitably used for institute
There is cementing cement head.
