Description
Technical field
The present invention relates to the pipeline rush repair equipment, relate in particular to a kind of expander be used to the pipeline that furthers.
Background technique
At present, petroleum pipeline mainly comprises spigot and socket type pipeline, trough pipeline, soft pipeline, because with a varied topography, unpredictable, it is inevitable to leak oily accident, particularly pipe joint pull phenomenon occur comparatively serious-because petroleum pipeline is to be formed by the several sections long standard pipes layings of 6m, if damage or underproof lock ring has been installed in the bellmouth, or joint does not connect when connecting, or warpage occurs in pressurization adjustment, substantially exceeded joint and allowed angle range, the pipeline socket connector just may come off out from the bellmouth joint, or is in the state that partly comes off.
When pipe joint occurring and pull phenomenon, traditional solution mainly is to lift by many people, the mode of instrument sled, and the pipeline that furthers and come off, but the method efficient is extremely low, and some working environment manpower can't be finished pipeline and connects.Pull pipeline for connecting fast, domestic a kind of pulling/pushing device once appearred, mainly comprise main anchor ear, secondary anchor ear, tractive ratchet wrench, ejection ratchet wrench and draw push rod etc., the advantage of this pulling/pushing device is the top of drawing of adopting single manual mode can finish the short distance pipeline, but still have 4 shortcomings: the one, pull distance is too little, only tens centimetres; The 2nd, the bolt arrangement mode is adopted in anchor ear locking, and development rate is slow; The 3rd, owing to adopt ratchet wrench structure, need manual control power large; The 4th, can only satisfy the connection of single diameter pipeline, can not take into account multiple pipeline demand.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this invention is to provide a kind of pipeline expander, it has advantage simple in structure, easy to operate, that transmission efficiency is high, driving force is little, and can adapt to multiple pipeline.
For achieving the above object, the present invention takes following technological scheme:
A kind of pipeline expander comprises support, is fixedly arranged on the reel on this support top and is positioned at the anchor ear of these support both sides; One of them anchor ear is connected with the movable tension rope of this reel, and another anchor ear is connected by the fixed strain rope with this support;
Described anchor ear comprises anchor ear and lower anchor ear, and two side of the two ends of anchor ear and this time anchor ear is hinged by bearing pin on this, thereby encloses containing space of structure; This time anchor ear two side also is provided with the vertical slideway that moves up and down for this bearing pin, and this vertical slideway is provided with several transverse slipwaies that communicate with this vertical slideway in addition to fix the position of this bearing pin; This time anchor ear both sides bearing pin is arranged in different transverse slipwaies so that the size of this containing space changes.
Described support is provided with rotary pressure plate, is pressed on the base plate of described reel; This rotary pressure plate and this support hinged and can one stationary axle be that axle rotates, this stationary axle is provided with locking nut.
Described reel comprises crank, mandrel, gear train, spool and movable tension rope; This crank is arranged in this mandrel, and this mandrel is connected by gear train with this spool; This activity tension rope volume is placed on this spool.
Described reel also comprises a ratchet that is used for locking described gear train; This ratchet is socketed return spring and connects one frees draw ring.
The two ends of the end of described movable tension rope, described fixed strain rope are equipped with Self-locking hanging hook.
Described support is provided with locking ring, and this locking ring and this support are hinged, and an end of described fixed strain rope is connected with this locking ring.
Described upper anchor ear top is provided with draw ring.
The invention has the beneficial effects as follows: the present invention adopts gear train transmission and crank type structure, and ratchet wheel pawl type release construction and mazy type hooping structure, can alleviate steering force, increases work efficiency and pull distance and can adapt to the installation of multiple pipeline; Fixedly reel adopts the presser type structure in addition, has greatly improved development rate.

Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.
As shown in Figure 1, the invention provides a kind of pipeline expander, be used for when pipe joint occurring and pull phenomenon the pipeline that furthers and come off, the anchor ear 3 that it comprises support 1, is fixedly arranged on the reel 2 on this support 1 top and is positioned at these support 1 both sides.One of them anchor ear is connected with the movable tension rope 21 of this reel 2, and another anchor ear is connected by fixed strain rope 4 with this support 1.
Such as Fig. 2, shown in Figure 3, this anchor ear 3 comprises anchor ear 31 and lower anchor ear 32, and two side of the two ends of anchor ear 31 and this time anchor ear 32 is hinged by bearing pin 33 on this, thereby encloses containing space of structure, and the pipeline that comes off namely is contained in this containing space.This time anchor ear 32 two sides also are provided with the vertical slideway 34 that moves up and down for this bearing pin 33, and in the process that this bearing pin 33 moves up and down, the size of this containing space changes thereupon, to adapt to the pipeline of different tube diameters.This vertical slideway 34 is provided with several transverse slipwaies 35 that communicates with this vertical slideway in addition, when this bearing pin 33 slips into this transverse slipway 35, namely fixes the position of this bearing pin 33.Like this, this time anchor ear both sides bearing pin is arranged in different transverse slipwaies can be so that the size of this containing space changes, and then can spur the pipeline of different tube diameters.
