Embodiment Construction
[0019] Attached below figure 1 The structure of the present invention is described in detail:
[0020] see figure 1 , the wellhead hydraulic blowout preventer lifting device mainly includes a blowout preventer 1, a blowout preventer adapter 2, a first union pressure cap 3, a first union adapter 5, a lifting sleeve 7, a lifting fixing seat 8, and a rotating handle 11. Second union adapter 12, second union pressure cap 13, union short circuit 15, lifting bracket 22, adjusting vertebral body 23, lifting cylinder 26, lifting piston 27, lifting cylinder 29, Lifting piston 30, oil distributor 31, hydraulic pump assembly 33 and other components.
[0021] The lifting bracket 22 is welded with titanium alloy plates, and the structure is set as a triangular living hinge connection bracket. Under the premise of not affecting the installation and movement interference, the inside of the lifting bracket 22 is welded with reinforcing ribs 28, thereby greatly improving the lifting capacity...

The invention relates to a wellhead hydraulic blowout preventer lifting device, which includes a union short-connect structure, a union transfer structure, a power source, a tripod, a lifting device and a lifting device; the tripod includes angles A, B and C; The lifting device is fixed on the AC side of the tripod formed from angle A to angle C of the tripod; the lifting device drives the union transfer structure for lifting movement; the lifting device includes a lifting fixed seat; the A angle of the tripod passes through the pin shaft The activity is set on the lifting fixed seat; the lifting fixed seat is fixedly connected with the union short-circuit structure; the lifting device is set between the B angle of the tripod and the lifting fixed seat; the lifting device drives the union transfer through the tripod The structure rotates around the pin shaft between angle A and the lifting fixed seat; the power source is connected with the lifting device and the lifting device respectively and provides power for the lifting device and the lifting device. The invention provides a wellhead hydraulic anti-nozzle pipe lifting device with a high degree of safety and is easy to carry and operate.
Description
technical field [0001] The invention belongs to the technical field of petroleum exploitation and relates to a mechanical device, in particular to a well head hydraulic nozzle pipe lifting device used in well logging and well testing operations. Background technique [0002] In oil field oil production operations, high-pressure water injection is often required to enhance oil recovery. When testing under high injection pressure, the length of the weighted rod must be increased, and the length of the blowout preventer must be increased accordingly. Workers stand in the operation Operation on the platform will inevitably cause the anti-spray pipe to swing from side to side. During the test, the operator needs to stand on the anti-spray pipe operating platform and tighten the pressure cap with a wrench to reduce the flow rate of the anti-spray overflow, which greatly increases the risk of work. Some oil production platforms have narrow space and small well spacing, and it is di...
