Abstract
The utility model relates to a locking-type hand clamping disc which is used for the technical field of a petroleum well service device, composed of a slip 2, a lever handle 5, a positioning slot 6, a positioning disc 7, an arresting pin 8, etc. The slip 2 is connected with a connecting plate 4 through a pin shaft 3; the positioning disc 7 is in bond fixation through a fulcrum shaft 12, and is provided with the positioning slot 6; the arresting pin 8 is arranged in the positioning slot 6 of the positioning disc 7. An oil pipe can be effectively prevented from falling into the well and the slip can be effectively prevented from entering a clamping disc.
Description
The utility model relates to a kind of locking type hand chuck in the petroleum well workover equipment technical field.
The tubing spider that uses has pneumatic and manual two kinds at present.Wherein hand chuck is reequiped design on former pneumatic chuck base plinth, relatively be applicable to widely used well workover equipment, but in use find following shortcoming: (1) is in well pulling job, when load gently (only remains several oil pipes), easily fall oil pipe, though this is because the oil pipe screw thread is turned on, because the gravity of screw thread top oil pipe, oil pipe is buckled with 1: 16 tapering in addition, still have the part screw thread to stay in the tubing coupling, when the workover treatment machine operation, also will on carry oil pipe, screw thread is all proposed box cupling, oil pipe could be put down, in this process, the oil pipe pin thread is often hung mutually with the box cupling box, cause the oil pipe that blocked by chuck to carry on also, because chuck do not have locking device, slips also with on carry, being blocked oil pipe unclamps, oil pipe is just fallen in the well, causes the accident.(2) when following oil pipe, slips proposes chuck body, because the position of slips can not lock, may because of carelessness slips be entered in the chuck body, causes oil pipe to be blocked suddenly, and operator has little time brake, and traveling system continues descending, collides with oil pipe, has an accident.
The purpose of this utility model is to provide a kind of can prevent effectively that oil pipe from falling in the well and slips enters a kind of locking type hand chuck of chuck.
The utility model is achieved in that by chuck body 1, slips 2, bearing pin 3, connecting plate 4, lever harrow 5, locating slot 6, positioning disk 7, latch 8, spring 9, pull bar 10, handgrip 11, fulcrum shaft 12, bearing pin 13 to be formed, slips 2 is connected by bearing pin 3 with connecting plate 4, lever harrow 5 is connected with bearing pin 13 with connecting plate 4, on lever harrow 5 medium positions fulcrum shaft 12 is arranged, stationary positioned dish 7 on the fulcrum shaft 12, positioning disk 7 has locating slot 6, latch 8 places the locating slot 6 of positioning disk 7, spring 9 is enclosed within on the latch 8, and latch 8, pull bar 10, handgrip 11 connect successively.
Advantage of the present utility model is: can prevent effectively that in well pulling job oil pipe from falling in the well, when oil pipe operation down, solve slips locking position problem and made slips can not enter chuck.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is positioning disk 7 structural representations of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further.
The utility model is made up of chuck body 1, slips 2, bearing pin 3, connecting plate 4, lever harrow 5, locating slot 6, positioning disk 7, latch 8, spring 9, pull bar 10, handgrip 11, fulcrum shaft 12, bearing pin 13, slips 2 is connected by bearing pin 3 with connecting plate 4, lever harrow 5 is connected with bearing pin 13 with connecting plate 4, on lever harrow 5 medium positions fulcrum shaft 12 is arranged, stationary positioned dish 7 on the fulcrum shaft 12, positioning disk 7 has locating slot 6, latch 8 places the locating slot 6 of positioning disk 7, spring 9 is enclosed within on the latch 8, and latch 8, pull bar 10, handgrip 11 connect successively.
Deploy a latch 85 times at lever harrow, promoted to be pressed on positioning disk 7 edge by spring 9, latch 8 links to each other with handgrip 11 with pull bar 10, carry on the handgrip 11 and can spur latch 8 actions, two grooves 6 are arranged on the positioning disk 7, by latch 8 can stationary slip 2 last, on the position, following two operating points, on the slips 2, following two operating positions can be by last handle 11 pulling connecting rods 10, compression spring 9 makes the location trough roller of latch 8 from the positioning disk 7 to another locating slot, be implemented at an oil pipe with when playing the oil pipe operation, the slips locking position misoperation can not occur.
