Technical scheme: a kind of concrete anchoring pull loader based on electric hydraulic servo, comprise the base being provided with track, vertically be fixed on the fixing steelframe on base, two ends are fixedly connected with the first bracing members with fixing steelframe with base respectively, the dolly that can move back and forth along described track, and be fixed on mobile steelframe on described dolly, counterweight and move the motor that power is provided for dolly; The light sensor described mobile steelframe being provided with hydraulic jack and being connected with described electric electromechanics.
In a further embodiment, the base secondary beam that described base comprises base girder, is fixedly connected with described base girder, and be fixed on base girder and base secondary beam to form the base cladding plate of base plane.Described fixing steelframe and described base cladding plate are welded and fixed.
In a further embodiment, loader also comprises two ends and is individually fixed in the second bracing members on mobile steelframe and dolly.Described first bracing members is fixedly connected by bolt and fixing steelframe and base; Described second bracing members is fixedly connected by bolt and mobile steelframe and dolly.Described mobile steelframe is made up of two root type steel, and the length direction correspondence along described shaped steel is provided with many row's lifting jack fixed orifices, is welded with ribbed stiffener between adjacent lifting jack fixed orifice.Described base girder and base secondary beam adopt HW250X250X14 shaped steel.
Beneficial effect: the present invention adopts motor, moveable carriage and light sensor to combine, according to test test specimen size horizontal adjustment loading position, and can not produce extruding to component.Leave 60mm gap and on steelframe, leave two row's lifting jack fixed orifices between the shaped steel of fixing steelframe and removable steelframe, loading position can be adjusted at vertical direction according to sample dimensions, and can realize loading load respectively in both sides.In a further embodiment, adopt common electric hydraulic jack and hollow electricity hydraulic jack can controlled loading process realize the loading of cyclic reverse loading.
Accompanying drawing explanation
Fig. 1 is loader elevation drawing of the present invention.
Fig. 2 is loader planimetric map of the present invention.
Fig. 3 is the structural representation that the present invention fixes steelframe and removable firm steelframe.
Fig. 4 a to Fig. 4 d is the operating diagram of the present invention under different operating mode.
Embodiment
As depicted in figs. 1 and 2, in this embodiment, based on the concrete anchoring pull loader of electric hydraulic servo, mainly comprise fixing steelframe 1, first bracing members 2, second bracing members 4, mobile steelframe 3, motor 5, counterweight 6, base cladding plate 7, base girder 8, base secondary beam 9, light sensor 10, dolly 11, centralized positioning line 12, trolley track 13, hollow electricity hydraulic jack 14 or common electric hydraulic jack 15 and control device composition.
Wherein, mobile steelframe, dolly and motor, counterweight composition horizontal loading position adjustment system.Contained by fixing steelframe and removable steelframe, between H profile steel, gap and lifting jack fixed orifice form vertical loading position adjustment system.
The base of base girder, base secondary beam and base cladding plate composition loader.Base cladding plate is provided with trolley track, and dolly can move back and forth along this track.Trolley track is made up of two one steel rails, is position line between rail.Fixing steelframe is fixed on base cladding plate, and the first bracing members provides support for fixing steelframe, prevents it from toppling over.Mobile steel chord position on dolly, and reliably connects.Motor and counterweight displacement dolly afterbody, motor provides power for dolly, and counterweight prevents removable steelframe from toppling.Hollow electricity hydraulic jack and common electric hydraulic jack can be fixed on fixing steelframe and removable steelframe.
With reference to figure 3, in a case study on implementation, fixing steelframe 1 and removable steelframe 3 are made up of two HW250X250-HW300X300 shaped steel, shaped steel spacing 60mm, two row's lifting jack fixed orifices are left, spacing 200mm in inner side, and between every holes, throat thickness is the thick ribbed stiffener of 10-12mm.Above-mentioned fixing steelframe 1 welds with base cladding plate 7.First bracing members and the second bracing members and other connected links with bolts.Above-mentioned light sensor 10 is connected on removable steelframe.Above-mentioned base cladding plate 7 adopts 10mm steel plate.Above-mentioned base girder and base secondary beam 9 all adopt HW250X250X14 shaped steel.Above steel components all adopts Q345 steel.
As shown in Figure 1, Figure 2 with shown in Fig. 4 a to Fig. 4 d, by lifting component on experimental provision, need test reinforcing bar and overlap with location center line, make it pass gap reserved in the middle of steelframe, test specimen side is near fixing steelframe.Motor 5 drives dolly and removable steelframe to move to component on trolley track, and when mobile steelframe and member contact, light sensor outgoing signal, dolly stops mobile.Corresponding lifting jack and the reinforcing bar that need test carried out connecting and be fixed on corresponding steelframe, lifting jack is controlled to carry out load test by control device.
