Description
Technical field
The utility model relates to a kind of stretch-draw machine annex, relates in particular to a kind of electronic pile for prestressed pipe tensioning nut locking device.
Background technology
Along with the raising of the significance level of modern building and the continuous increase of building height; Bearing capacity to ground is had higher requirement, and subsoil can better not born the load that upper building transmits, so when using subsoil to put up building; A kind of processing mode of strengthening bearing capacity is arranged; Promptly use armored concrete to do the foundation pile of ground, with pile press machine stake being pressed into becomes foundation pile after underground, lets foundation pile top carry building.Piling as the foundation pile engineering is more on market, if any pile tube, all kinds of side stake, bored concrete pile, drilled pile etc.It is cylindric that pile tube is, and it is through the at a high speed rotation on centrifuge of centrifugal pile tube mould, makes in the pile tube mould concrete do the high speed centrifugation motion, is made into the concrete tubular pile of central zone circular hole at last.This technology is very ripe, has got into large-scale industrial production.China uses and has all stipulated corresponding standard for the design production of this type stake.For example " Code for design of building " (GB5007～2002) and " pretensioned prestressed concrete pipe pile " (GB13476～2009).In conjunction with the production of China's pretensioned prestressing pile tube and the situation of application, the pile tube behind centrifugal forming adopts maintaining process twice: once for atmospheric steam curing, once for autoclave curing (still kettle maintenance).
The pile tube production unit need use the stretch-draw machine that pile tube master muscle is carried out stretch-draw when producing pile for prestressed pipe, makes it produce prestressing force.Along with the application and the popularization of pile for prestressed pipe, its output increases gradually in recent years, uses the stretch-draw machine equipment more and more frequent.See also Fig. 1, it is the operation principle sketch map of stretch-draw machine, and the hydraulic jack of stretch-draw machine is passed to tensioning head 12 tensile force fs 1 through stretch-draw cover 11; The reaction force F2 of tensile force f 1 acts on the end plate 211 of pipe die 21 through square head; Main muscle 22 is carried out stretch-draw, behind the stretching force that reaches setting, by the workman is manual tensioning nut 13 is tightened again; Tensioning nut 13 is leaned against on the end plate 21, finish back maintenance prestressing force thereby be implemented in stretch-draw.
Yet, need walk around the side of stretch-draw machine when by hand tightening tensioning nut, slowly tighten tensioning nut with manpower, spend the more production time, and, needing bigger power during the locking tensioning nut, efficient is low.In addition, in process of production, because wearing and tearing or other reasons cause tensioning head 12 phenomenon to occur pulling through regular meeting, at this moment, because the catastrophic failure of power, it is dangerous that tensioning nut 13 meeting generations are tightened in manual work, and this type of accident happens occasionally.
In sum, have in the prior art that artificial locking tensioning nut is time-consuming, effort, efficient is low and the technical problem of causing danger easily.
