Technical Field

The utility model relates to a torque wrench technical field, concretely relates to ultra-thin hydraulic torque wrench of breach formula.

Background

The hydraulic torque wrench is a power tool for fastening and disassembling the bolt, the hydraulic pump station provides a power source, the oil pipe transmits high-pressure oil to the hydraulic torque wrench, and the high-pressure oil pushes the plug rod to drive the shaft to rotate, so that the bolt is fastened and disassembled by matching with the sleeve. The output repetition precision of the hydraulic torque wrench reaches +/-3%, and the high precision of the torque enables the hydraulic torque wrench to be widely applied to construction, maintenance and repair work in the industries of ship engineering, petrochemical industry, wind power and hydropower, mining machinery, steel mill pipelines and the like.

However, the operating radius of the conventional hydraulic torque wrench working head is limited, so that the hydraulic torque wrench cannot be put in a narrow space, and the hydraulic torque wrench cannot work. At this moment, the traditional mode of manually using a knocking wrench is often adopted, the bolt is fastened and disassembled through a sledge hammer or a chain block, but the safety of personnel cannot be guaranteed in the mode, and the torque precision of the bolt cannot be guaranteed.

Therefore, a new hydraulic torque wrench is needed to overcome the insecurity and unscientific nature of manual striking.

SUMMERY OF THE UTILITY MODEL

To above technical problem, the utility model provides an ultra-thin hydraulic torque wrench of breach formula to make hydraulic torque wrench can use under the operating mode in narrow and small space, make its work fastening and dismantle the bolt, solved the insecurity and the unscientific nature that the manual work was strikeed.

In order to achieve the above object, the utility model provides a following technical scheme:

ultra-thin hydraulic torque wrench of breach formula includes:

the oil cylinder is internally provided with a piston rod, and the end of the piston rod is provided with a clamping hook;

the cushion block is arranged at the right lower part of the oil cylinder;

the upper cover and the lower cover are assembled to form a cavity communicated with the inner cavity of the oil cylinder, and the upper cover and the lower cover are fixed at the left lower part of the oil cylinder after being assembled;

the ratchet wheel is partially embedded in the cavity, and a hexagonal transition sleeve is arranged on the inner ring of the ratchet wheel;

the upper end of the push wheel ring component is clamped on the clamping hook, and the lower end of the push wheel ring component is meshed with the ratchet wheel;

one end of the stop block is meshed with the ratchet wheel, and the other end of the stop block is connected with the push wheel ring assembly through a spring.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses can make hydraulic torque wrench can use under the operating mode in narrow and small space, make its work fastening and dismantle the bolt, solve the insecurity and the unscientific nature that the manual work was strikeed.
