Abstract
The utility model discloses a mouse hole drill rod padding fork used in petroleum industry. A hole opening of a mouse hole of a well-drilling drill floor is used for clamping a drill rod to guarantee safety of operation and facilitating make and break operations of the drill rod. The mouse hole drill rod padding fork comprises a padding fork body which is provided with a U-shaped slot, a stop rod and a connecting pin rod, and the connecting pin rod and a fixing pin rod are mutually connected in insertion mode and fixed to each other through a fixing pin. By means of the connection between the fixing pin rod and the connecting pin rod and fixing effect of the stop rod, the padding fork body is fixed in a hole opening of a mouse hole. The padding fork body does not rotate when a drill rod rotates, and the drill rod can not move forwards and backwards on the padding fork body, accordingly high timeliness and excellent safety performance are obtained. When making up or breaking out the drill rod, a user only needs laying down or lifting the padding fork body through tools of iron hooks and the like instead of manual padding. The mouse hole drill rod padding fork is simple in manufacture and convenient in installation and operation.
Description
Technical field
The utility model relates to the aid of petroleum drilling engineering, and mouse hole drill rod padding fork particularly is used in the hole of drilling well rig floor mouse hole, and the clamping drilling rod guarantees job safety, and what make things convenient for drilling rod goes up button and shackle operation.
Background technology
When mouse hole was the single or breaking down column operation of drilling crew's stacks, the transfer lay down location of drilling rod was for making things convenient for going up button and must establishing with shackle operation institute of drilling rod.Drilling crew is equivalent to portable cover plate at the mouse hole fork of usefulness at present, in the lifting process of drilling rod, needs manually it to be put in the hole of mouse hole, and complex operation is not only gone up, during shackle, and fork also can be along with the drilling rod in connecting rotates.Work limitation is poor, and its tail rope that is connected the mouse hole hole is easily broken, need manually be placed on the mouse hole hole in the advance expenditure process, and make it placed in the middle, if misoperation also can weigh incidents such as finger wounded, causes security incident, and potential safety hazard is big.
Summary of the invention
The purpose of this utility model provides the mouse hole drill rod padding fork, overcomes the above-mentioned defective that existing mouse hole drill rod padding fork exists.Reduce potential safety hazard, prevent that the mouse hole fork from detain on drilling rod and shackle process in rotate, handled easily is increased work efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: the mouse hole drill rod padding fork comprises the fork body, the fork body is provided with the U-shaped socket, also be provided with arresting lever on the fork body and be connected pin rod, connect pin rod and fixedly pin rod grafting, fix with steady pin.By fixing pin rod fixation, the fork body is fixed on the hole of mouse hole with connection that is connected pin rod and arresting lever.
The utility model compared with prior art has following useful effect: the both sides at fork body U-shaped socket are provided with arresting lever, and fork body shank is connected with the mouse hole pipe with fixing pin rod by connecting pin rod, and the fork body is fixed by 3, and stability is good.The fork body no longer rotates during the drilling rod rotation, and drilling rod can not move forward and backward on the fork body, the timeliness height, and security performance is good.Button and during shackle on the drilling rod need not by manual advance expenditure again, puts down and start the fork body as long as use iron such as colludes at instrument.The utility model manufacturing is simple, easy for installation, and is easy to operate.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a lateral view of the present utility model.
Fig. 3 is the connection pin rod of the present utility model and the fixing connection diagram of pin rod.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.Referring to Fig. 1 and Fig. 2, the mouse hole drill rod padding fork comprises fork body 2, and fork body 2 is provided with the U-shaped socket, also is provided with arresting lever 1 on the fork body 2 and connects pin rod 3 and 4, connects pin rod 3 and 4 and pegs graft with fixing pin rod, fixes with steady pin 8.Arresting lever 1 is located at the U-shaped socket both sides of fork body 2.With the edge setting of arresting lever 1 near fork body 2, the position cooperates with the inwall size of mouse hole pipe, can be lived by the mouse hole pipe clamp, increases stability of the present utility model, in the connection procedure of drilling rod, makes fork body 2 can not produce bigger moving.Connect the shank that pin rod 3 and 4 is located at fork body 2, its front end end is provided with pin-and-hole, and steady pin 8 can be latch or bolt.Referring to Fig. 3, fixedly pin rod comprises fixedly pin rod 5,6 and 7, and fixedly pin rod is connected with the mouse hole pipe or welds.Fixedly pin rod is provided with one at least, has a fixedly pin rod and mouse hole pipe welding or is connected at least, be exactly the fixedly pin rod 6 between connection pin rod 3 and 4.Connecting pin rod 3 and 4 and fixedly intert steady pin 8 in the pin rod, by pin 9 or nut locking.Connect pin rod 3 and 4 and fork body 2 can rotate around steady pin 8.Instrument such as collude by iron during use, rotation fork body 2 covers at the mouse hole, by arresting lever 1 and fixing pin rod 5,6 and 7 fork body 2 is fixing.When in the mouse hole pipe, putting into drilling rod, start fork body 2, when drilling rod is lowered to appropriate depth, put down fork body 2, by of the box end advance expenditure of U-shaped socket drilling rod.
