Abstract
The utility model discloses a side limiting mechanism of a clamping block. The side limiting mechanism comprises a tooth plate and a base. A translational guide mechanism and a translational limiting mechanism are arranged between the base and the tooth plate. The base and the tooth plate can move horizontally along the translational guide mechanism. A vertical unlocking portion and a vertical locking portion are arranged between the base and the tooth plate. When the base and the tooth plate move to the vertical unlocking portion, the tooth plate can move longitudinally relative to the base. When the base and the tooth plate move to the vertical locking portion, the vertical locking portion limits the tooth plate to move vertically relative to the base. When the side limiting mechanism needs to be replaced and the tooth plate is detached from the base, what is needed is to press a movable check block to achieve limiting unlocking, and operations are easy and convenient.
Description
Technical field
The utility model relates to a kind of oil drilling and extracting equipment field, particularly a kind of position-limit mechanism of the side for the quick-changing type grip block.
Background technology
Injection head is for removing the key equipment of continuous-tube in the continuous-tube rig, when injection head is removed the work of continuous-tube, all must rely on clamping device that continuous-tube is clamped, its general process is oil cylinder pushing or pulls clamping device to move to the center of continuous-tube, thereby extruding is with grip block and the continuous-tube laminating of half slot dental lamina, and produce enough large frictional force, then under the drive of chain traction mechanism, promote or transfer continuous-tube, in order to mate the continuous-tube of different tube diameters, now increasing injection head has all adopted the grip block mechanism of fast changeable grip block dental lamina.
Wherein a kind of mode is to adopt the mode of cassette, grafting to connect dental lamina and pedestal.For example, in the United States Patent (USP) that is US6173769B1 at publication number " Universal carrier for grippers in a coiled tubing injector ", the grip block mechanism of disclosed a kind of replaceable clamping dental lamina, wherein, be provided with lug in the both sides of dental lamina (as this patent Fig.8, Fig.9, position shown in mark 191 in Fig.12), be provided with draw-in groove for holding lug in the inboard of pedestal (as this patent Fig.8, Fig.14, position shown in mark 195 in Fig.16), insert draw-in groove by lug, dental lamina is plugged on pedestal, when dental lamina is installed, at first the application of force is pressed on the pedestal surface by spring leaf by dental lamina, along draw-in groove, slide again, until dental lamina touches the fixed end on pedestal, again spring card is entered in the sheet groove of pedestal opposite side, dental lamina is fixed, pedestal has adopted draw-in groove to peg graft mode with dental lamina is connected, when the dismounting dental lamina, by spring leaf (as this patent Fig.8, position shown in mark 199 in Fig.16) firmly depress, make lug enter in the height of draw-in groove, again dental lamina is slided along draw-in groove, can take out, or installation dental lamina.Although aforesaid way is of value to the quickly dismantled of dental lamina and pedestal, but in use, because only depending on spring leaf, it carries out locked and release, because spring leaf is very thin, its rigidity along the spring-compressed direction is also poor, when creeping into, drill bit is passed to the impact shock on injection head, very easily makes spring leaf inefficacy release, causes dental lamina to come off from pedestal.
Chinese utility model patent " a kind of coiled tubing injection head floating clamping device " (notification number: CN202000930U) improve for the problems referred to above, adopt bolt structure to carry out spacing to a side of dental lamina, coordinate again locking glue or other locking way, can avoid getting loose of screw to a great extent, thereby the problem of having avoided above-mentioned United States Patent (USP) (patent No.: US 6173769 B1) to exist, but its new problem of bringing is, while changing dental lamina, all to pull down dog screw, simultaneously due to certain locking measure being arranged on dog screw, make the work of changing dental lamina become loaded down with trivial details.
