Abstract
The utility model discloses a sleeve pipe fast-dismounting thread protector, which belongs to a petroleum drilling sleeve pipe tool, and overcomes the defects that in the prior art, the sleeve pipe thread protector easily deforms, and the fast mounting and dismounting cannot be easily realized. The sleeve pipe fast-dismounting thread protector is formed by a sleeve pipe fast-dismounting thread protector body, a hinge and a self locking handle mechanism through connection, wherein the body is formed by hinging two semicircular sleeve pipe steel pipe thread protectors through the hinge, a handle of the self locking handle mechanism is arranged on the outer pipe wall of one side of the body through a fixing pin, the positioning pin is arranged on the outer pipe wall of the other side, the handle and the positioning pin are in mutual contact, and the contact surfaces of the handle and the positioning pin are respectively taper circular arc surfaces.
Description
Technical field: the utility model relates to the oil drilling sleeve tool, especially a kind of sleeve pipe quick-release thread protector.
Background technology: in drilling engineering, beaten after the drilling depth electrical measurement finishes, need in well, be lowered to sleeve pipe.During setting of casing, sleeve pipe need be pulled on rig floor from the place, put into mouse hole, mention buckling button with tourist bus and casing elevator again, be lowered to institute's drilling well intraocular.Before the pipe of helping pull a cart is gone up rig floor, must be with thread protector with protection pin thread screw thread, behind the last rig floor, unload thread protector again.Owing to easily bump, hang tag during rig floor on the sleeve pipe, cause the thread protector distortion; Casing screw protector exists screw thread long, many simultaneously; What the scene was commonly used is iron sheet parcel plastic type thread protector mostly, also yielding; Several reasons cause casing screw protector can not go up fast, unload, and have influenced setting of casing speed, cause the construction timeliness low.
Summary of the invention: the utility model purpose provides a kind of simple, fast a kind of sleeve pipe quick-release thread protector, it overcomes the casing screw protector mutability of prior art, the defective of unloading on being difficult for fast, the purpose of this utility model is to realize like this, it is to be formed by connecting by sleeve pipe quick-release thread protector body, hinge and self-locking handle mechanism, and body is managed and protected silk by two semicircle casing steels and formed by hinge is hinged; The handle of self-locking handle mechanism is installed on the body one side outer tube wall by steady pin, and alignment pin is installed on the outer tube wall of opposite side.Handle and alignment pin are in contact with one another, and handle and alignment pin contact surface are the tapering arc surface.
During use, two semicircle casing steels of body are managed and protected silk and are opened under the hinged effect of hinge, be fastened on the sleeve pipe pin thread screw thread, two the semicircle casing steels of body that close are managed and protected silk, press down handle, handle rotates around steady pin, makes steady pin and alignment pin produce pulling force, and two semicircle casing steels of body are managed and protected silk locking.On the handle of raising one's hand, remove the pulling force of steady pin and alignment pin, open two semicircle casing steels of body and manage and protect silk, take off fast from sleeve pipe pin thread screw thread.
The utility model adopts casing steel to manage and protect the hinged of silk and hinge, the quick opening and closing of realization casing screw protector; Utilize self-locking handle mechanism, the quick locking that realizes casing screw protector and sleeve pipe pin thread screw thread with separate.Sleeve pipe quick-release thread protector is simple in structure, easy to operate, has alleviated working strength of workers, has improved setting of casing speed and construction timeliness, has reached the purpose of speed-raising synergy.
Description of drawings: Fig. 1 is a kind of sleeve pipe quick-release thread protector structural representation, among the figure 1, body 2, hinge 3, steady pin 4, handle 5, alignment pin
Fig. 2 is the structural representation of self-locking handle mechanism, among the figure 3, steady pin 4, handle 5, alignment pin
