Abstract
The utility model discloses a large-tonnage flange plate double-acting hydraulic jack which comprises a cylinder body. The large-tonnage flange plate double-acting hydraulic jack is characterized in that a bottom cover is arranged at one end of the cylinder body in a sealing mode, a flange plate is arranged on the outer end portion of the other end of the cylinder body, a guide sleeve is clamped in the other end of the cylinder body in a sealing mode, a piston rod is arranged in the cylinder body, a piston at one end of the piston rod is in pilot fit with the inner wall of the cylinder body, a pressure bearing plate is arranged at the other end of the piston rod, a piston rod between the guide sleeve and the piston is sleeved with a supporting ring, an oil inlet channel communicated with the inner cavity of the cylinder body is formed in one side of the piston on the cylinder body, an oil return channel communicated with the inner cavity of the cylinder body is formed in the other side of the piston, and a hydraulic lock respectively communicated with the oil inlet channel and the oil return channel is arranged between the oil inlet channel and the oil return channel. The large-tonnage flange plate double-acting hydraulic jack is reasonable in structural design, and has the advantages of being simple in structure, small in size, small in operation force, low in labor intensity, flexible in piston ascending and descending transformation, high in speed, light and the like.
Description
technical field
The utility model relates to a kind of jacking accessory, relates in particular to the two hydrodynamic pressure jacks of a kind of large-tonnage flange.
Background technology
Jack is widely used in the operations such as jacking in building engineering, shipbuilding, metallurgy, mining, petrochemical complex, railway construction and other industry, stretching, extrusion.Existing jack structure is simple, and fixing inconvenience is installed, and hand labor intensity is large, wastes time and energy, and firmly poor performance, exists potential safety hazard, the difficulty that simultaneously resets, and also the piston wear of jack is severe, and service life is short.
Utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, provides a kind of large-tonnage flange two hydrodynamic pressure jacks.
The utility model is achieved through the following technical solutions:
The two hydrodynamic pressure jacks of a kind of large-tonnage flange, include cylinder body, it is characterized in that: one end of described cylinder body is sealed and installed with bottom, the cylinder body outer end of the other end is provided with flange, in the cylinder body of the other end, sealed card is equipped with orienting sleeve, in described cylinder body, be provided with piston rod, the piston of described piston rod one end coordinates with inboard wall of cylinder block guiding, the other end of piston rod is provided with bearing plate, piston rod between described orienting sleeve and piston is set with support ring, described cylinder body upper piston one side is provided with the oil inlet passage being communicated with inner chamber of cylinder block, piston opposite side is provided with the drainback passage being communicated with inner chamber of cylinder block, between described oil inlet passage and drainback passage, be provided with the hydraulic lock being communicated with respectively with it.
Its principle is: oil cylinder top is furnished with flange for connection, convenient fixing, jacking safety, double acting, hydraulic reposition, can join the saddle of turning to reduce the impact of unbalance loading on oil cylinder, oil cylinder can reach range two not to be damaged, piston rod through heat treatment He Du Chrome process, to reduce the wearing and tearing between piston rod and support ring.Being furnished with hydraulic lock device, can obtaining the top lifting height needing in travel position locking load arbitrarily, is the critical component of realizing the functions such as self-locking, location, pressurize, has further guaranteed the stable and personnel's of load safety in operating process.In hydraulic lock, be provided with one-way throttle valve, can city's load steadily decline.The high pressure hose that quick joint is housed is connected jack with oil pump, convenient, the flexible safety of mounting or dismounting can, away from the operation of operation place, be conducive to guarantee safety in dangerous operation.
The utility model has the advantages that:
The utility model reasonable in design, has the features such as simple in structure, volume is little, operating effort is little, labour intensity is low, piston lifting conversion is flexible, speed is fast, lightweight.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing, the two hydrodynamic pressure jacks of a kind of large-tonnage flange, include cylinder body 1, one end of cylinder body 1 is sealed and installed with bottom 2, the cylinder body outer end of the other end is provided with flange 3, the interior sealed card of cylinder body 1 of the other end is equipped with orienting sleeve 4, in cylinder body 1, be provided with piston rod 5, the piston of piston rod 5 one end coordinates with inboard wall of cylinder block guiding, the other end of piston rod 5 is provided with bearing plate 6, piston rod between orienting sleeve 4 and piston is set with support ring 7, cylinder body 1 upper piston one side is provided with the oil inlet passage 8 being communicated with inner chamber of cylinder block, piston opposite side is provided with the drainback passage 9 being communicated with inner chamber of cylinder block, between oil inlet passage 8 and drainback passage 9, be provided with the hydraulic lock 10 being communicated with respectively with it.
