In figure：Walking mechanism 1, tensioning mechanism 2, connect retaining mechanism 3, base 4, roller 5, guide rail 6, hydraulic cylinder 7, jack 8, hydraulic power unit 9, screwed pipe 10, clamping body 11, sleeve pipe 12, inserting column 13, draw ring 14, erecting bed 15, handgrip 16, convex block 17, pedestal 18.
Embodiment
As shown in Figure 1, a kind of framework of steel reinforcement tensioning equipment, including walking mechanism 1, tensioning mechanism 2 and connection retaining mechanism 3, the walking mechanism 1 includes base 4, base 4 is arranged on guide rail 6 by roller 5, guide rail 6 is consistent with the length direction of electric bar mould, the tensioning mechanism 2 includes hydraulic cylinder 7, jack 8, hydraulic cylinder 7 is arranged on base 4, and the elongation of the piston rod of hydraulic cylinder 7 is controlled by hydraulic power unit 9, connecting pole axis collinear on the piston rod central axis of hydraulic cylinder 7 and the framework of steel reinforcement of electric bar mould, the jack 8 is symmetrically mounted on the both sides of hydraulic cylinder 7, coordinate with hydraulic cylinder 7, realize tensioning, the connection retaining mechanism 3 includes the screwed pipe 10 being connected with the connecting pole on framework of steel reinforcement and the clamping body 11 being connected with the piston rod of hydraulic cylinder 7.
As shown in Fig. 2 the clamping body 11 includes the sleeve pipe 12 welded with screwed pipe 10, sleeve pipe 12 is provided with through hole, and inserting column 13 is provided with through hole, and inserting column 13 realizes clamping through the through hole on sleeve pipe 12 and the piston rod of corresponding hydraulic cylinder 7.
The upper end of inserting column 13 is hinged with draw ring 14.Thus facilitate and take out inserting column, while play spacing effect.
As shown in Figure 3-4, the clamping body 11 includes the bolted erecting bed 15 of piston rod with hydraulic cylinder 7, for the outside of erecting bed 15 circumferentially at least provided with two pedestals 18, the top of handgrip 16 is be hinged with erecting bed 15 and is arranged on by bearing pin on pedestal 18, can be slided up and down along pedestal 18.During work, when hydraulic cylinder piston rod shrinks, the one side of handgrip 16 rotates along the pin joint of erecting bed 15, and multiple handgrips are realized and screwed pipe is firmly grasped；On the other hand, handgrip is slided up and down by bearing pin along pedestal chute, makes the motion of handgrip have directionality.In addition, bearing pin both ends are cambered surface, friction can be reduced.
The pedestal is three, circumferentially distributed along erecting bed 15.Thus structure, when capturing, realization is circumferential firmly grasps, guarantee uniform force, and the connecting pole on reduction framework of steel reinforcement causes the thread abrasion above connecting pole because of local pressure inequality.
