Description

Technical Field

[0001] The utility model relates to the field of hydraulic wrenches for Christmas trees, in particular to a hydraulic wrench special for Christmas trees. Background Art

[0002] The hydraulic wrench converts hydraulic energy into mechanical energy through the hydraulic system. When the hydraulic pump starts, hydraulic oil is pumped into the hydraulic cylinder, causing the piston to move forward. The pressure of the hydraulic oil is transmitted to the wrench head through the piston, generating torque. When the hydraulic pump stops working, the hydraulic oil is blocked from flowing, the piston stops moving, and the torque on the wrench head also stops being generated.

[0003] The Christmas tree is a key component connecting the wellhead and oil production equipment. The bolts on it need to be frequently tightened or removed for maintenance or replacement using a Christmas tree hydraulic wrench. However, the drive plate components on some hydraulic wrenches are fixed in size and difficult to remove. Different hydraulic wrenches need to be replaced when installing and removing nuts or screws of different specifications. Therefore, maintenance personnel need to be equipped with multiple hydraulic wrenches of different specifications, which is inconvenient to use and reduces the maintenance efficiency of the Christmas tree.
