Abstract
The utility model discloses a kind of new security slip with the chain body formed by the mutual connection chain links; at the two ends of the chain body are installed the mutually locking device; on the chain link of the chain body is installed the tooth plate device. The utility model is reasonable in structure, simple in operation, safe and reliable; only by loosening the nut can the blocking pipe of the chain link be opened.
Description
Technical field:
The utility model relates to that a kind of oil bores, in the workover treatment, prevent from not have shoulder or do not have the fall insurance of well of box cupling tubing string slippage to hold instrument.
Background technology:
Existing safety slip all need be extracted terminal pivot pin when holding tubing string, again pivot pin is inserted original position after holding tubing string, then chucking.Complex structure, troublesome poeration, safety in utilization is undesirable.
Summary of the invention:
The purpose of this utility model is to provide new type of safe slips a kind of rational in infrastructure, simple to operate, safe and reliable.
Technical solution of the present utility model is:
A kind of new type of safe slips is characterized in that: the catemer that has chain link to be interconnected to, the two ends of the catemer mechanism that interlocking is closed of pretending, dress dental lamina device on the chain link of catemer.
The two ends of the catemer mechanism that interlocking closes of pretending comprises the type that the colludes carrier bar that is connected with catemer one end, and the other end of catemer connects leading screw, adorns feed screw nut on the leading screw, and the inboard dress of feed screw nut will collude the briquetting that the type carrier bar compresses.The dental lamina device comprises the dental lamina cover that is connected with chain link, the inboard dress of dental lamina cover dental lamina.Adorn handle on the catemer.
The utility model is rational in infrastructure, and is simple to operate, safe and reliable, only need unclamp nut, just can open chain link and hold tubing string.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
A kind of new type of safe slips, the catemer that has chain link 1 to be interconnected to, the two ends of the catemer mechanism that interlocking is closed of pretending, dress dental lamina device on the chain link 1 of catemer by bearing pin 2.The two ends of the catemer mechanism that interlocking closes of pretending comprises the type that the colludes carrier bar 8 that is connected with catemer one end, and the other end of catemer connects leading screw 9, dress feed screw nut 10 on the leading screw 9, and feed screw nut 10 inboard dresses will collude the briquetting 11 that type carrier bar 8 compresses.The dental lamina device comprises the dental lamina cover 4 that is connected by bearing pin 5 with chain link 1, and dental lamina overlaps 4 inboards and installs dental lamina 3 by dental lamina backing pin 6, dress handle 7 on the catemer.Also has spacer pin 12 among the figure.
The utility model is pressed on briquetting 11 by leading screw 9, feed screw nut 10 and colludes on the type carrier bar 8, and each chain link is formed a closed round ring holds tubing string.Unclamp feed screw nut 10, mobile briquetting 11, rotational lead screw 9 then can and collude type carrier bar 8 and throw off briquetting 11, opens chain link.
