Abstract
The utility model provides an anti-deviation device for a puller. The anti-deviation device comprises a guide rail, pulling bed frames, rollers and locking mechanisms, wherein one or more roller groups are arranged on the pulling bed frames; each of the roller group comprises two rollers arranged on the two sides of each pulling bed frame symmetrically; the rollers are near to the relative side surfaces of the guide rail and are movably connected with connecting shafts in a sleeving manner; the connecting shafts are arranged vertical to the ground; a supporting mechanism is arranged at the end near to the ground of each connecting shaft; the other end of each connecting shaft is fixedly connected with the pulling bed frames through the locking mechanisms. The anti-deviation device for the puller provided by the utility model is simple in structure and easy to operate, and can ensure that the puller travels straightly during a moving process.
Description
Technical field
The utility model relates to a kind of drawbench, especially a kind of anti-drawbench centring device.
Background technology
In oil exploitation, need inner with spiral fluted steel pipe, therefore while producing this inside with spiral helicine steel pipe, one outside being provided with to spiral fluted core inserts in a steel pipe stator, then pour into a mould with jelly, cooling and with drawbench, core is extracted by stator steel pipe after good with steel pipe is bonding until jelly, in actual life, the drawing bedstead of drawbench bottom is generally provided with a logical rod, bedstead both sides and guide rail corresponding section are provided with the hook plate that prevents drawbench perk in drawing process, while carrying out drawing by manually drawbench being carried out to drawing to core after guide rail is pushed into assigned address, after drawing again by manually retracting, because this device does not have guider, in the time of mobile drawbench, the easy sideslip of drawbench, at this moment hook plate easily and guide rail side collision, drawbench is difficult for pulling, and wear and tear for a long time owing to hooking plate one end, cause the center line centering of drawbench hydraulic cylinder center line and core fixture to decline, the easy perk of drawbench in the time carrying out core drawing, drawing does not go out core.
Utility model content
Problem to be solved in the utility model is to provide a kind of anti-drawbench centring device, in drawbench moving process, adjusts by this device travel direction, guarantees that drawbench motion track is a straight line substantially, and does not damage hook plate.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anti-drawbench centring device, comprises guide rail, drawing bedstead, roller and retaining mechanism; On described drawing bedstead, be at least provided with a roller set, this roller set comprises two rollers, described two rollers are symmetrically set in the both sides of described drawing bedstead, and each roller is near the corresponding side of guide rail, the equal movable sleeve of described roller is connected to connecting axle, the equal vertical ground setting of described connecting axle, and described each connecting axle is equipped with supporting mechanism near one end, ground, and the other end is all affixed by retaining mechanism and drawing bedstead.
Further, the distance of the wheel rim of described roller and guide rail side is 0.5mm.
Further, described roller set is two groups, lays respectively at the front-end and back-end of drawing bedstead.
Further, described connecting axle is bolt, and described retaining mechanism is the first nut.
Further, described connecting axle is provided with the second nut between roller and guide rail.
Advantage and the good effect that the utlity model has are:
1). simple in structure, be convenient to manufacture and operation;
2). in drawbench moving process, under two side wheel actings in conjunction, guarantee the movement of drawbench substantially along a straight line;
3). drawbench moves under two side wheel effects, has reduced the friction of drawbench hook plate and guide rail, has guaranteed preferably the centering of drawbench hydraulic cylinder center line and core fixture center line.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is left side schematic diagram;
In figure: 1, drawing bedstead, 2, the first nut, 3, connecting axle, 4, roller, 5, guide rail, 6, the second nut.
The specific embodiment
Now by reference to the accompanying drawings the utility model is elaborated, as shown in Figure 1 and Figure 2, a kind of anti-drawbench centring device, comprises guide rail 5, drawing bedstead 1, roller 4 and retaining mechanism; On described drawing bedstead 1, be at least provided with a roller set, this roller set comprises two rollers 4, described two rollers 4 are symmetrically set in the both sides of described drawing bedstead 1, and each roller 4 is near the corresponding side of guide rail 5, and the equal movable sleeve of each roller 4 is connected to connecting axle 3, the equal vertical ground setting of described connecting axle 3, and described each connecting axle 3 is equipped with supporting mechanism near one end, ground, and the other end is all affixed by retaining mechanism and drawing bedstead 1.
Further, the distance of the wheel rim of described roller 4 and guide rail side is 0.5mm; This gap length can compensate the foozle of guide rail, guarantees normally travelling of drawbench.
Further, described roller set is two groups, lays respectively at the front-end and back-end of drawing bedstead 1; When drawing bedstead 1 moves, the roller 4 of front end both sides and the roller 4 of both sides, rear end are adjusted simultaneously and limit its mobile alignment, have further guaranteed the linearity that it moves.
Further, described connecting axle 3 is bolt, and described retaining mechanism is the first nut 2; This simplicity of design, pair roller is played a supporting role simultaneously, has save the supporting mechanism for support roller.
Further, described connecting axle 3 is provided with the second nut 6 between roller 4 and guide rail 5; In drawbench moving process, when roller and guide rail contacts side surfaces generation rolling, the second nut 6 plays and prevents that roller from moving axially the effect of getaway.
Implement when the utility model, roller 4 to be socketed on bolt 3, more then the second nut 6 is screwed into bolt 3 is screwed into drawing bedstead 1, then lock with the second nut 6; When mobile drawbench, in the time that drawbench departs from predetermined shiftable haulage line, roller 4 and guide rail 5 contacts side surfaces and roll, prevent the further sideslip of drawbench, thereby make the working line of drawbench within the specific limits, and then in claimed range, guaranteed the centering of hydraulic cylinder center line and the core fixture center line of drawbench.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model scope, within all should still belonging to this patent covering scope.
