Abstract
The utility model relates to a reshaper for a padding fork of a drilling machine, comprising upright posts, a chassis, top covers, a die holder, a die cover and a jack. The reshaper is characterized in that the two upright posts are vertically fixed on the chassis, the top coves are fixed on the top ends of the two upright posts, the die holder is fixed between the two upright posts on the chassis, a U-shaped padding fork is arranged on the die holder, the die cover is arranged on the top end of the U-shaped padding fork, and the jack is pressed on the die cover. The reshaper is suitable for adjusting and restoring the shape of the U-shaped padding fork on the drilling machine. The reshaper has the advantages of simple structure, convenient use, fast restoration of deformed padding fork, guaranteed quality of restored padding fork, prolonged service life of padding fork, increased efficiency of perforation construction and reduced construction cost, and is the ideal reshaper for the padding fork of the drilling machine.
Description
Technical field
The utility model relates to a kind of parts shaping mould, and particularly a kind of rig fork reshaper is applicable to the shape of adjusting " U " shape fork on the rig and makes it to restore to the original state.
Background technology
At present, in the making hole construction of pitshaft, the effect of " U " shape fork is: the junction in that rig up and down blocks drilling rod, weighted lever or drill collar during drilling tool, be fixed on the rotating disk of rig, and the plus-minus drilling tool ensures safety." U " shape fork that steel plate is made deforms under the effect of alternation, impact stress easily through using the back repeatedly, makes original " U " v notch v increasing, and progressively becomes " V " v notch v.Will cause U like this " shape fork card do not live drilling tool, often falls the brill accident.Particularly in the freezing hole construction process below 400 meters, every processing was once fallen the brill accident 3 to 5 days at least, 10 days first quarter moons at most, even may cause freezing hole to scrap, up to a hundred meters drilling tool total losses.Therefore, the effective ways that solve the brill accident are to recover " U " shape fork to original form.And current fork recovers mainly to realize by operations such as cutting, weld, forge, not only wastes time but also can not guarantee the fork quality, has caused very big waste economically.
The utility model content
The purpose of this utility model is: design a kind of simple in structure, easy to use, can fast quick-recovery distortion fork, and can guarantee to recover the rig fork reshaper of back fork quality, in order to overcome the deficiencies in the prior art.
The purpose of this utility model can realize by following technical proposals:
This rig fork reshaper, form by column, chassis, top cover, die holder, die cap and jack, it is characterized in that: two root posts vertically are fixed on the chassis, top cover is fixed on the top of two root posts, die holder is fixed on position between two root posts on the chassis, " U " shape fork is placed on the die holder, and die cap is placed on " U " shape fork top, and jack presses on die cap.
Die holder described in the utility model is equipped with the corresponding draw-in groove of convex edge size with " U " shape fork by being bolted on the chassis on described die holder and the die cap.
The top of two root posts of the present utility model links together with top cover by encircling the week welding, and the outside of two root posts and top cover junction is provided with stiffener.
Inboard between two root posts of the present utility model and the top cover, and the front side between two root posts and the chassis, rear side and the outside are equipped with reinforcement.
Chassis described in the utility model is formed by the two-layered steel plates assembly welding.
Top cover described in the utility model is the casing shape structure that six block plates are welded.
Jack described in the utility model is hydraulic jack or screw jack.
The utility model has the advantages that: simple in structure, easy to use, quick-recovery distortion fork, and the fork quality after can guaranteeing to recover soon, prolonged the service life of fork, having improved drilling construction efficient, reduced construction cost, is a kind of desirable rig fork reshaper.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is a plan structure schematic diagram of the present utility model.
The specific embodiment
As shown in figure 12, this rig fork reshaper, form by column 3, chassis 1, top cover 9, die holder 4, die cap 6 and jack 7, two root posts 3 are the drilling rod of diameter 89mm, and two root posts 3 vertically are fixed on the chassis 1, and top cover 9 is fixed on the top of two root posts 3, die holder is fixed on position between The One On The Chassis two root posts 3, " U " shape fork 5 is placed on the die holder 4, and die cap 6 is placed on " U " shape fork 5 tops, and jack 7 presses on die cap 6.Described die holder 4 is equipped with the corresponding draw-in groove of convex edge size with " U " shape fork 5 by being bolted on the chassis 1 on described die holder 4 and the die cap 6.The top of two root posts 3 links together with top cover 9 by encircling the week welding, and two root posts 3 are provided with stiffener 8 with the outside of top cover 9 junctions.Inboard between two root posts 3 and the top cover 9, and front side, rear side and the outside between two root posts 3 and the chassis 1 are equipped with reinforcement 2.Described chassis 1 is that the steel plate assembly welding of 25mm forms by two layers of thickness.Described top cover 9 is the casing shape structure that steel plate that six thickness are 25mm is welded.Described jack 7 is 50 tons of hydraulic jack or screw jack.
During use, " U " shape fork 5 of distortion is placed between the die holder 4 and die cap 6 of this rig fork reshaper, upper and lower two convex edges of " U " shape fork 5 are stuck in the draw-in groove on die holder 4 and the die cap 6, jack 7 presses on die cap 6, manually-operated jack 7, " U " shape fork 5 is stressed in this reshaper, and " U " shape fork 5 of distortion is progressively restored to the original state.In construction, after using tens times usually, just scraps " U " shape fork 5, after using this reshaper shaping, can recover " U " shape fork of a distortion in 20 minutes, both improve the service life of each fork, improved drilling construction efficient again, reduced operating expenses.
