Abstract
The utility model relates to and provides a spiral displacement support device for an oil sieve tube. The spiral displacement support device for the oil sieve tube comprises a fixed sleeve, an active adjusting nut, a thrust rolling bearing, a blocking cap, a locating pin and a movable sleeve. A thread is processed in an outer circle of the fixed sleeve and an inner circle of the active adjusting nut and forms screw drive. The thrust rolling bearing is arranged on the upper end surface of the active adjusting nut and is capable of alleviating friction in the process of the screw drive. The blocking cap which is disposed outside the thrust rolling bearing has the protection function. The fixed sleeve is provided with a horizontal hole and the locating pin. A blind hole at the outer circle of the active adjusting nut is stirred so as to drive the locating pin and the movable sleeve to move in the vertical direction to support and drive a tube to displace in the vertical direction, but height of center of a clamp is unchangeable.
Description
Affiliated technical field
The utility model relates to a kind of Petroleum screen tube spiral displacement bracing or strutting arrangement, can be according to the vertical shift position that do not coexist of petroleum casing pipe external diameter, and the center height of anchor clamps is constant.
Background technology
For the ease of clamping, in the process of Petroleum screen tube deep processing, require the center height of anchor clamps of clamping pipe constant.But the size of the petroleum casing pipe external diameter of each processing changes, and therefore requires bracing or strutting arrangement can adjust in vertical.
Summary of the invention
For the ease of clamping, satisfy bracing or strutting arrangement in the adjustable requirement of vertical, the utility model provides a kind of Petroleum screen tube spiral displacement bracing or strutting arrangement, utilizes worm drive to be implemented in the vertical displacement.In order to alleviate the labour intensity of adjustment, thrust bearing has been installed, in the process of worm drive, guiding mechanism becomes rolling friction by sliding friction, has reduced coefficient of friction, realizes light adjustment.
The utility model solves the technical scheme that its technical problem adopted: a kind of Petroleum screen tube spiral displacement bracing or strutting arrangement is provided, by fixed muffle 1, initiatively adjusts nut 2; Thrust bearing 3, door 4, alignment pin 5; Quill 6 is formed; It is characterized in that: said fixed muffle 1 with initiatively adjust nut 2 and form worm drive, thrust bearing 3 and door 4 are equipped with in the upper surface of initiatively adjusting nut 2, alleviate the frictional force in the worm drive process.
Said fixed muffle 1 is equipped with alignment pin 5, when thrust bearing 3 is shifted in vertical, drives quill 6 and moves, thereby support and drive the pipe displacement.
The beneficial effect of the utility model is, can be according to the vertical shift position that do not coexist of petroleum casing pipe external diameter, and the center height of anchor clamps is constant.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
1. fixed muffles among the figure are 2. initiatively adjusted nut, 3. thrust bearing, 4. door, 5. alignment pin, 6. quill.
The specific embodiment
In accompanying drawing 1, the cylindrical of said fixed muffle 1 is processed with screw thread with the interior circle of initiatively adjusting nut 2, forms worm drive.Thrust bearing 3 is equipped with in the upper surface of initiatively adjusting nut 2, can alleviate the frictional force in the worm drive process.Be contained in the door 4 of thrust bearing 3 outsides, play protective action.
Said fixed muffle 1 is processed with cross-drilled hole, and alignment pin 5 is housed.Stir the blind hole of initiatively adjusting nut 2 cylindricals and can drive alignment pin 5 and quill 6 and move, be shifted in vertical thereby support and drive pipe in vertical.
Claims (2)
