Description
Technical field
The utility model relates to hydraulic spanner, especially a kind of hollow hydraumatic spanner.
Background technology
Hydraulic spanner is used to a kind of hydraulic tool of pretension or dismounting high-strength bolt nut, and it is widely used in the field such as electric power (nuclear power, wind-powered electricity generation, water power, thermoelectricity), boats and ships, metallurgy, traffic, cement, building, aviation.Its feature is: adopt superhigh intensity light metal, thin design, double acting, and at a high speed, large corner plug-in, exchanges working head, do not need special tool(s), and moment of torsion repeatable accuracy, up to ± 3%, is applicable to compact occasion, convenient location.
Some this driving hydraulic spanner as shown in figure tri-, figure tetra-adopted of occasion of current tools for bolts ' pretension dismounting.It in use, counter-force arm support to add a stop sleeve on adjacent bolt and nut, pre-load nut to be put a sleeve, cost increase, operation inconvenience.Especially can not use when the upper and lower space of bolt of equipment is less at all.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of novel hydraulic spanner, and it is simple and compact for structure, is applicable to operate in less space.
A kind of hydraulic spanner being applicable to less space of the utility model, it comprises oil cylinder, counter-force arm, swivel joint, force transmitting board, transmission mechanism; Swivel joint is fixed on oil cylinder, and two hydraulic fluid ports on it are connected with rod chamber with the rodless cavity of oil cylinder respectively; Groove is all processed in cylinder end and the piston rod outside of oil cylinder, and cylinder end is enclosed within the left end of counter-force arm, and by pinned connection, piston rod is enclosed within the top of force transmitting board, and passes through pinned connection; The other end of counter-force arm is processed into groove, and the processing of the both sides of groove is porose, is enclosed within the bottom of force transmitting board; The bottom hollow of force transmitting board, is provided with transmission mechanism in it.
Wherein, transmission mechanism comprises ratchet, ratchet, and ratchet is arranged in the groove above force transmitting board, and engages with ratchet.Like this, ratchet can directly be enclosed within the nut of needs dismounting, and need not, by an additional sleeve, therefore dismantle convenient.
The utility model hydraulic spanner, by oil cylinder, force transmitting board, counter-force arm three being joined end to end, forms the structure of an enclosed, and whole spanner structure is simple, compact, and the equipment that is applicable to is dismantled bolt, nut in less space up and down.

Detailed description of the invention
From accompanying drawing, a kind of hydraulic spanner being applicable to less space of the utility model, it comprises oil cylinder 1, counter-force arm 2, swivel joint 3, force transmitting board 4, transmission mechanism; Swivel joint 3 is fixed on oil cylinder 1, and two hydraulic fluid ports on it are connected with rod chamber with the rodless cavity of oil cylinder 1 respectively; Groove is all processed in cylinder end and piston rod 5 outside of oil cylinder 1, and cylinder end is enclosed within the left end of counter-force arm 2, and by pinned connection, piston rod 5 is enclosed within the top of force transmitting board 4, and passes through pinned connection; The other end of counter-force arm 2 is processed into groove, and the processing of the both sides of groove is porose, is enclosed within the bottom of force transmitting board 4; The bottom hollow of force transmitting board 4, is provided with transmission mechanism in it.
Wherein, transmission mechanism comprises ratchet 6, ratchet 7, and ratchet 7 is arranged in the groove above force transmitting board 4, and engages with ratchet 6.Like this, ratchet 6 can directly be enclosed within the nut of needs dismounting, and need not, by an additional sleeve, therefore dismantle convenient.
In order to make ratchet 6 locate more accurately, as a kind of improved procedure that this is novel, hydraulic spanner also comprises lining 8, snap ring 9, and snap ring 9 is arranged in the groove of counter-force arm 2, and lining 8 two ends contact with snap ring 9, ratchet 6 respectively.
The operation principle of the utility model hydraulic spanner is as follows: hydraulic pump hydraulic oil out enters the rodless cavity of oil cylinder 1 by swivel joint 3, and promote piston rod 5 and move right, the fluid of rod chamber gets back to the fuel tank of hydraulic pump from swivel joint; Under the effect of piston rod 5, force transmitting board 4 turns clockwise, and namely force transmitting board 4 promotes ratchet 7, and ratchet 7 promotes ratchet 6, and ratchet 6 promotes bolt and nut and rotates clockwise; When piston rod 5 arrives limit on the right-right-hand limit, pumping plant commutates, and rod chamber comes oily, and rodless cavity oil return, piston rod 5 is to left movement, and force transmitting board 4 rotates counterclockwise go back to home position.So repeatedly, thus the object reaching tools for bolts ' pretension or dismantle.
The utility model spanner, by oil cylinder, force transmitting board, counter-force arm three being joined end to end, forms the structure of an enclosed, and whole spanner structure is simple, compact, and the equipment that is applicable to is dismantled bolt, nut etc. in less space up and down.Meanwhile, because six sides of the ratchet of spanner directly contact with bolt and nut, without the need to an additional pretension sleeve and stop sleeve, thus reduce cost, easy to operate.
