Through the prop of the utility model can realize stable, flexible lifting effect, while having aesthetic and actor safety, solve the multiple restrictions of existing mechanical lifting art device in safety, adaptability and operating efficiency, difficult to meet the flexibility and cost benefit demand of different stage performance and other technical problems.

The invention provides a horizontal well liquid drainage system, method and device, a storage medium and electronic equipment, and belongs to the technical field of oil and gas development. The horizontal well liquid drainage system comprises an oil pipe, the oil pipe is arranged in a horizontal well, one end of the oil pipe is connected with a well mouth of the horizontal well, the other end of the oil pipe extends to a horizontal well section of the horizontal well in the underground direction along the horizontal well, and an opening is formed in the end, close to the horizontal well section, of the oil pipe; the dragging force device is arranged in the oil pipe, and the outer side wall of the dragging force device is attached to the inner side wall of the oil pipe; and the control device is used for controlling the towing device to reciprocate in the oil pipe. The control device is used for controlling the towing force device to move, so that liquid in the horizontal well is lifted from a lower position to a higher position, liquid drainage in a horizontal well section in a mechanical lifting mode is achieved, liquid drainage is more sufficient, and the production requirements of oil and gas well production in the later period are met.

The application discloses a kind of mechanical lifting automatic grabbing mechanism and grabbing method, including bearing frame, lifting hook support, lifting hook and limiting rod;Lifting hook support is arranged below longitudinal beam, and the inner side of lifting hook is sequentially provided with first inclined plane, grabbing plane, limiting vertical surface and second inclined plane from bottom to top;Limiting rod is outwardly inclined and arranged on the outer side of lifting hook support, and the inner side of limiting rod is provided with magnetic block at lower part.The present application is a pure mechanical automatic grabbing mechanism, which realizes two-step opening through the first and second inclined planes on the inner side of the lifting hook, and is combined with the magnetic block on the limiting rod after opening to be adsorbed and kept, saving electronic components, grabbing, lifting, pulling and hoisting of high-temperature smelting cylinder, and efficiently solving the bottleneck of mass production of new energy vehicle parts (including steering knuckles) smelting technology.

The invention relates to a mechanical lifting column (1) having a first hollow profile (2), a second hollow profile (3), a spring element (4), at least one lever assembly (5) and a holding mechanical structure (6). The first hollow profile (2) has a first longitudinal direction (L1) and the second hollow profile (3) has a second longitudinal direction (L2). The first longitudinal direction (L1) of the first hollow profile (2) and the second longitudinal direction (L2) of the second hollow profile (3) extend along a common, preferably vertical direction. The second hollow profile (3) is telescopically movable from a retracted position, in which the first hollow profile (2) is arranged substantially completely in the second hollow profile (3), into an extended position, in which the first hollow profile (2) is arranged only partially in the second hollow profile (3).
