Description

The fishing device of rope drilling tool

Technical field

The utility model relates to a kind of fishing device of rope drilling tool, specifically core-drill(ing) machine works the device of putting two-tube assembly in using rope drilling tool drilling technology process, can realize reliably throwing in and the lifting coring device, belong to engineering machinery (rig, drilling tool) technical field.

Background technology

Carry out in the process of core drilling at rig, how will need the interior pipe of muck core to render in the drilling rod reliably, how interior pipe is fished for after filling core reliably, it is the action that in the core drilling process, often repeats, the practicality of this device and reliability are very important, though all there is implementation method separately in each producer, on structure and reliability, be not quite similar, because of the complexity of geological condition and the versatility restriction of drilling tool.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, can satisfy the core drilling construction and the time throws in reliably, fishes for interior pipe thereby provide a kind of, thereby reach the fishing device of the final purpose rope drilling tool that reduces accident rate, increases work efficiency.

The technical scheme that provides according to the utility model, the fishing device of rope drilling tool adopts recovery hook to be fixed on by second pin and salvages on the frame, have groove in the middle of salvaging frame, the tail end of recovery hook is equipped with spring and struts, spring is fixed by rivet, the front end of recovery hook is equipped with first pin, with the open degree of control recovery hook, salvages frame and weight by being threaded.Weight and joint are formed one by the 3rd pin, the 4th pin, the 5th pin attachment security pin respectively.Joint is by being threaded onto on the gland.On the described joint lubricating cup is installed, gland is enclosed within on the connecting rod, and the plane bearing assembly is equipped with in the lower end, and tightens with slotted nut, packing ring, adds cottor pin and plays safety effect.Connecting rod is connected with the cable clamp external threading, therebetween tight rope the core of the card and wire rope.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; Implementation procedure is simple, reliable in action, safe and convenient, fishing device to drilling tool is had higher requirement, the target that general, simple, reliable fisher has become each producer to develop mutually unexpectedly, throw in reliably in the time of satisfying the core drilling construction, fish for interior pipe, thereby reach the final purpose that reduces accident rate, increases work efficiency.

The specific embodiment

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

As Fig. 1-shown in Figure 6, comprise recovery hook 1, first pin, 2, second pin 3, salvage frame 4, spring 5, rivet 6, take off card pipe 7, drag for spearhead 24, bullet card chamber 25 etc. on the weight 8, the 3rd pin 9, safety pin 10, the 4th pin the 11, the 5th pin 12, lubricating cup 13, joint 14, the 6th pin 15, nut 16, packing ring 17, bearing assembly 18, gland 19, connecting rod 20, cable clamp cover 21, wire clips core 22, inner tube assembly.

The utility model recovery hook 1 is fixed on by second pin 3 and salvages on the frame 4, have groove in the middle of salvaging frame 4, the tail end of recovery hook 1 is equipped with spring 5 and struts, spring 5 is fixing by rivet 6, the front end of recovery hook 1 is equipped with first pin 2, with the open degree of control recovery hook 1, the normal condition of recovery hook 1 is salvaged frame 4 and weight 8 by being threaded for closing (rear end has spring to strut).Weight 8 and joint 14 are formed one by the 3rd pin the 9, the 4th pin the 11, the 5th pin 12 attachment security pins 10 respectively.Joint 14 is by being threaded onto on the gland 19.Lubricating cup 13 is installed on the described joint 14, and gland 19 is enclosed within on the connecting rod 20, and plane bearing assembly 18 is equipped with in the lower end, and tightens with slotted nut 16, packing ring 17, adds 15 safety effects of cottor pin.Connecting rod 20 and cable clamp cover 21 are threaded therebetween tight rope the core of the card 22 and Ф 5 wire rope 23.Take off the outside that card pipe 7 is enclosed within package unit weight 8, be in free state.

The operating principle of the present utility model and the course of work:

The salvaging process: the tong-like structure is formed by a pair of recovery hook 1 in the lower end, its tail end is strutted by spring 5, make front end be in closure state all the time, the weight tenesmus of playing and relying on weight 8 and package unit topmost by Ф 5 wire rope, strike and drag for spearhead 24 and open automatically when (as shown in Figure 6) and fasten the step that drags for spearhead 24 immediately, finally realize salvaging lifting.

Safeties:

Safety pin 10 is a bronze medal spare, and the thinnest place diameter is Ф 5mm, is hampered powerfully to rise at first to disconnect to protect other drilling tools when pulling out.

Take off the safety effect of card pipe 7, when extraction is hampered, can throws in and take off card pipe 7, the front end that takes off the card pipe has certain chamfering gradient, at first oppresses the afterbody of recovery hook 1 when descending, causes the front end of hook to strut to discharge drilling tool.

The single action function: pair of planar bearing assembly 18 can satisfy 19 times end devices of gland and follow the drilling rod rotation, prevents to produce relative motion between fishing device and the drilling rod inwall, produces friction and damages drilling tool.

Launch process: when managing in throwing in, hook earlier with recovery hook 1 and to drag for spearhead 24, after to be put the putting in place, take off card pipe 7 from the top input, the afterbody of compressing recovery hook 1 discharges drilling tool, fishing device just can propose the aperture, can not fall down at the step place of salvaging frame 4 and take off card pipe 7 retainings, proposes the aperture with fishing device.
