Embodiment
As shown in Fig. 1~Fig. 7, the utility model includes support set 5, cylinder body 2, piston 3, nut 1, screw rod 8, baffle plate 4;Branch Support set 5 is located at the upper plane in the turnbuckle hole of cross girder 13, and cylinder body 2 is located at the top of support set 5;Piston 3 is arranged on cylinder body 2 It is interior, positioned at the top of support set 5;Nut 1 is arranged on the top of cylinder body 2, and screw rod 8 runs through cylinder body 2 through nut 1;Baffle plate 4 is installed In the lower section of cylinder body 2, it is fixedly connected by hexagon socket cap head screw 9 with cylinder body 2.Baffle plate 4 is loaded on cylinder body bottom, limits stroke Highly, it is ensured that will not be long due to taut length and cause the generation of the phenomenon of rupture of turnbuckle 11.
The lower end of screw rod 8 is connected through a screw thread to be connected with turnbuckle 11;The upper end of turnbuckle 11 and tightening nut 10 It is connected, the lower end of turnbuckle 11 passes through cross girder 13;Nut 1 is connected through a screw thread with screw rod 8, is drawn during installation according to different The size that the tight top of bolt 11 tenses screw thread is designed to the inner hole thread of screw rod 8, is easy to General design.It is equipped with cylinder body 2 Air bleeding valve 7, is easy to the oily chamber air of emptying, prevents unbalance loading phenomenon from producing;The side of cylinder body 2 is provided with oil inlet 14, oil inlet 14 connect hydraulic hand-pump or electric hydraulic pump.
Support set 5 of the present utility model is put in beam surface upper, is that screw rod 8 elongates the offer elongation of turnbuckle 11 space, The bottom of support set 5 offers notch, is easy to rotation tightening nut 10 and reads the anglec of rotation.Tightening nut 10 is located at cross girder 13 top, is contacted with the top surface of cross girder 13.Seal 12 is provided with cylinder body 2.
In use, two sets of hydraulic pressure pulling devices are diagonally installed.During installation, by the inner hole thread of screw rod 8 and turnbuckle 11 threaded upper ends are connected, and support set 5 is placed in the tapping of the upper surface turnbuckle 11 of cross girder 13, then piston 3 is placed on On support set 5;By cylinder body 2 loaded on piston 3, sealing forms oil cylinder;Then nut 1 is screwed on screw rod 8, until nut 1 is twisted Untill tight;Baffle plate 4 is finally loaded on the bottom of cylinder body 2, installation.During pressurization, the plug cock of oil inlet 14 need to be removed access hand Hydraulic oil is injected in hydrodynamic press pump or electric hydraulic pump, the seal oil chamber formed to cylinder body 2 with piston 3, and (oil pressure need to be counted in advance Calculate) produce thrust.In the utility model, piston 3 is static, and oil pressure produces thrust and promotes cylinder body 2 to move upwards, drives Nut 1 is moved upwards, and nut 1 is connected through a screw thread drive screw rod 8 and moved upwards, and screw rod 8 is connected through a screw thread drive and tenses spiral shell Bolt 11 is moved upwards, and the stress of turnbuckle 11 is just elongated, now, the upper end tightening nut 10 of turnbuckle 11 and cross girder top Contact surface produces gap, tightening nut 10 manually at this moment is rotated into required angle, then emptying, completes the pre- of turnbuckle 11 Tightly.Before pressurization, air bleeding valve 7 need to be opened, be easy to exclude the air in cavity, tightened again when thering is hydraulic oil to emerge, If not draining air in cavity, oil pressure skewness can be caused and unbalance loading phenomenon is produced, easily cause security incident.
Compared with the prior art, the bottom of the utility model piston 3 process seam and the upper end of support set 5 process end face and Coordinate between cylindrical, it is ensured that the uniform force of support set 5 during pressurization, improve device stability.The present apparatus is under static state to gear Rational spacing is devised between plate 4 and piston 3, can not only maximum height limit effectively prevent because tense it is highly excessive and caused by draw The fracture of tight bolt, moreover it is possible to reduce pressurization number of times, workman is only rotated a tightening nut can complete to tense requirement, improve Operating efficiency.
In embodiment of the present utility model, each basic part is simple in construction, it is easy to process using conventional material.Baffle plate 4 Ensure the range of cylinder body 2, it is not only safe and reliable, moreover it is possible to improve operating efficiency;Device is stable, easy to operate simple;Versatility It is extremely strong, it is cost-effective;While the utility model fault rate is low, service life is long.
Above-mentioned embodiment is not that, to limitation of the present utility model, the utility model is also not limited to the example above, The variations, modifications, additions or substitutions that those skilled in the art are made in the range of the technical solution of the utility model, Also protection domain of the present utility model is belonged to.
