Abstract
The utility model relates to a manufacturing device for a pretensioning method prestress concrete pile, and in particular to a tension device for a prestress tubular pile or a prestress square pile. The tension device comprises a pipe mould framework, an end plate, a tension end fixing plate, a clamp, a lead screw and a lead screw connecting plate, wherein a guide sleeve is mounted at one end of the lead screw connecting plate, and a return spring is sleeved on the lead screw. Compared with the prior art, in the tension device, the guide sleeve is additionally mounted on the lead screw connecting plate, more even tension distribution is ensured during tension, meanwhile, the guide sleeve can prevent concrete from entering the fixed part of a mould during material feeding, and the return spring on the lead screw is used for the automatic reposition of the lead screw connecting plate so as to further reduce workers' labor intensity.
Description
Technical field:
The utility model relates to the pretensioning prestressed concrete pile manufacturing installation, particularly a kind of tensioning equipment for pile for prestressed pipe or square pile.
Background technology:
The manufacture process of pretensioning prestressed concrete pile is: the cage muscle two ends of roll welding moulding are installed the end plate assembly, then the mould of packing into interior (in the counterdie), one end is installed in the stretch-draw tailgate on the end plate assembly with bolt, the other end is installed in stretch board on the end plate assembly with bolt, then stretching support board is installed successively, the stretch-draw leading screw, then nut loads concrete, and mould closes, stretch-draw, centrifugal, steam-cured, put and open, form removal, remove a terminal bolt, a pile is produced complete, needs stretch board in this production process, gripper shoe, the stretch-draw leading screw, the whole dismounting of tensioning nut one time, labor strength is very large, production efficiency also is affected, and scheme of installation is shown in figure one.Present most production unit adopts above-mentioned stretching mode.
Figure two is the tensioning equipment after improving, basis at former tensioning equipment increases clip and connecting plate, during dismounting, be dismounting clip and connecting plate, other workpiece is stayed mould (in the counterdie), and workman's work greatly reduces, and production efficiency is improved, tensioning equipment after this improvement is just to begin to use in nearly 2 years, and applying unit is relatively less.Although among the figure two the modified tensioning equipment figure one be improved, but still exist certain defect to have much room for improvement, die bolt needn't all be opened at every turn when unloading, tensioning equipment also needs to reset etc.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of tensioning equipment that is used for pile for prestressed pipe or square pile that can reset.
The utility model adopts following technical scheme:
A kind of tensioning equipment for pile for prestressed pipe or square pile comprises the pipe die skeleton, end plate, and the stretching end fixed head, clip, leading screw, the leading screw connecting plate, an end of described leading screw connecting plate is equipped with fairlead, is set with back-moving spring on the described screw mandrel.
Adopt the utility model of technique scheme compared with prior art, install fairlead additional at the leading screw connecting plate, stretching force distributes more even when guaranteeing stretch-draw, concrete entered the standing part of mould when fairlead can prevent feeding simultaneously, back-moving spring on leading screw, being used for the leading screw connecting plate labor strength that automatically resets can further reduce.
Preferred version of the present utility model is:
Described stretching end fixed head is fixed in an end of pipe die skeleton.
Described stretching end fixed head is fixed in an end of pipe die skeleton by connector.
Description of drawings:
Fig. 1 is a kind of structural representation of prior art.
Fig. 2 is the structural representation of another kind of prior art.
Fig. 3 is structural representation of the present utility model.
Wherein among Fig. 1: pipe die skeleton 1, leading screw connecting plate 2, end plate 3, stretch-draw leading screw 4, tensioning nut 5, stretching end fixed head 6.
Among Fig. 2: pipe die skeleton 1, leading screw connecting plate 2, end plate 3, stretch-draw leading screw 4, tensioning nut 5, stretching end fixed head 6, clamp connection plate 7, clip 8, handle hole 9.
The specific embodiment:
Below in conjunction with embodiment in detail the utility model is described in detail:
A kind of tensioning equipment for pile for prestressed pipe or square pile, referring to accompanying drawing 3, among the figure: pipe die skeleton 1, leading screw connecting plate 2, end plate 3, leading screw 4, tensioning nut 5, stretching end fixed head 6, clamp connection plate 7, clip 8, back-moving spring 10, connector 11, fairlead 12.
In the present embodiment, an end of leading screw connecting plate 2 is equipped with fairlead 12, is set with back-moving spring 10 on the screw mandrel 4.One end of leading screw 4 is equipped with tensioning nut 5.Stretching end fixed head 6 is fixed in an end of pipe die skeleton 1 by connector 11.
Leading screw connecting plate 2 is contained in an end of leading screw 4, between leading screw connecting plate 2 and the clamp connection plate 7 clip 8 is housed, and a side of clamp connection plate 7 is equipped with end plate 3.
Fairlead 12 has 1 to 2 millimeter gap with the inwall of pipe die skeleton 12.
Present embodiment has following advantage in application process: patrix is divided into two bodies, the part patrix of tensioning equipment namely is installed is no longer opened, the operating time is saved in so at least 4 at every turn dismounting of die bolt.
Stretching end fixed head 6 is bolted together to the end of pipe die skeleton 1, stops to cause stretching force not uniform because of foreign material such as two junction adhesion cement.Install fairlead 12 additional at leading screw connecting plate 2, stretching force distributes more even when guaranteeing stretch-draw, rod iron length is difficult for breaking when inconsistent, concrete entered the standing part of mould when fairlead 12 can prevent feeding simultaneously, install back-moving spring 10 additional at leading screw 4, be used for leading screw connecting plate 2 and automatically reset, what back-moving spring 10 produced oppositely also firmly can ignore, and labor strength can further reduce.
At leading screw 4 reseting pressuring spring 10 is installed, after taking mould taking-up stake apart, unscrew tensioning nut 5, leading screw connecting plate 2, leading screw 4 and fairlead 12 are at back-moving spring 10(stage clip) effect under, homing need not manually to retract, and the opposition that reseting pressuring spring 10 provides can be ignored to the negative function of stretch-draw.Only need pull down front band when tearing open, stake can be taken out, and lower catch hoop can be stayed and need not dismounting in the mould.
