Embodiment 1

[0032] refer to Figure 1-8 As shown, a mechanical slip oil pipe anchor includes a central pipe 1 and an upper joint 2 and a lower joint 3 which are sequentially sleeved outside the central pipe 1, and slips are sleeved and installed between the upper joint 2 and the lower joint 3 4. The outer sleeve of the slip sheet 4 is equipped with a matching finishing mechanism, and the top of the central tube 1 is equipped with a locking mechanism matching the upper joint 2 .

[0033] The finishing mechanism includes a transmission box 15 fixed on the front side of the central tube 1 through a connecting block 21. The top of the slip sheet 4 is provided with a pressing ring 5, and the middle outer wall of the slip sheet 4 is symmetrically installed with a pressing ring 5. The pad 26 set against the lower end surface of the ring 5, a rack bar 12 is slidably inserted in the transmission box 15, and the top of the rack bar 12 is provided with a limit frame 11 fixed on the outer wall of the...

Embodiment 2

[0036] On the basis of Embodiment 1, two fixed sleeves 8 are symmetrically fixed to the left and right sides of the rack bar 12 on the outer wall of the slip sheet 4, and columns 7 are slidably inserted in the two fixed sleeves 8, and the tops of the two columns 7 Both are fixed by the fixing block 6 and the outer wall of the pressing ring 5, and the bottoms of the two columns 7 are fixedly equipped with anti-off columns 10, and the two columns 7 are equipped with springs 9, and the ends of the two springs 9 The two ends are set against the fixed sleeve 8 and the anti-falling cylinder 10 at the first and last ends of the two columns 7 respectively.

[0037] In this embodiment: through the elastic return ability of the column 7, the fixed sleeve 8, and the spring 9, the up and down stable movement of the pressing ring 5 driven by the rack bar 12 is realized, and the regularity of the pressing ring 5 when it moves vertically is improved. .

Abstract

The invention discloses a mechanical slip tubing anchor, and relates to the technical field of tubing fixing equipment. The mechanical slip tubing anchor comprises a central tube, an upper joint and a lower joint, wherein the upper joint and the lower joint are sequentially arranged outside the central tube in a sleeving mode; a slip piece is arranged between the upper joint and the lower joint in a sleeving mode; a collecting mechanism matched with the slip piece is arranged outside the slip piece in a sleeving mode; a clamping and limiting mechanism matched with the upper joint is arranged at the top of the central tube; the collecting mechanism comprises a transmission box body fixed on the front side of the central tube through a connecting block; a pressing sleeve ring is arranged at the top of the slip piece in a sleeving mode; cushion blocks which abut against the lower end surface of the pressing sleeve ring are symmetrically arranged on the outer wall of the middle of the slip piece; a rack rod is inserted into the transmission box body in a sliding mode; and a limiting frame body fixed on the outer wall of the pressing sleeve ring is arranged at the top of the rack rod in a sleeving mode. According to the mechanical slip tubing anchor, a rotating shaft is rotated through an electric tool so as to drive a gear to realize upward movement of the pressing sleeve ring, so that strong folding of the slip piece is realized, and the easy-to-disassemble characteristic of an anchoring part is guaranteed as much as possible.

Description

technical field [0001] The invention relates to the technical field of oil pipe fixing equipment, in particular to a mechanical slip oil pipe anchor. Background technique [0002] The task of oil production engineering is to make oil and gas flow into wells smoothly through a series of engineering and technical measures that can act on oil reservoirs, and the wells can efficiently lift them to the ground for separation and metering; its goal is to economically and effectively improve oil and gas. Crude Oil Recovery. From the point of view of system engineering, oil production engineering is an important subsystem in the central position in the large oil field production system, which is closely related to oil reservoir engineering and field oil and gas gathering and transportation engineering. Tar and petroleum have been used for thousands of years. Artesian oil, gasoline, and tar are found all over the world. The famous Los Angeles La Brea tar pits (La Brea tarpits) is a...
