Description
Technical Field
[0001] The utility model relates to the technical field of oil well operation, in particular to a pipe rack support leg. Background Art
[0002] During oil well operations, tubing and pump rods are placed on a pipe rack, supported by tubing columns underneath. These columns are called pipe rack legs. Traditional "pipe rack legs" have the following drawbacks: 1. The height adjustment screws are exposed and easily contaminated, compromising operation; 2. The support head and adjustment screws are integrated. Once the tubing is in place, height adjustment requires removing the tubing and unloading the load, making the process cumbersome. In light of these issues, we conducted in-depth research, leading to this proposal. Utility Model Content

[0005] The side wall of the adjustment seat is provided with an assembly hole in the horizontal direction, and an adjustment rod is inserted into the assembly hole.
[0006] The outer ring surface of the lower end of the adjustment seat is provided with an external thread, and the inner ring surface of the upper end of the protective sleeve is provided with a thread groove, and the thread groove matches the external thread.
[0007] The above-mentioned rotation support component includes a bearing, a fixed shaft and a rotation support member. An annular assembly groove is opened at the center position of the upper end surface of the adjustment seat. The bearing is installed in the annular assembly groove. The lower end of the fixed shaft is inserted into the bearing and has an interference fit with the inner ring of the bearing. The upper end of the fixed shaft is connected to the support. The rotation support member is installed on the adjustment seat and is arranged coaxially with the fixed shaft.
[0008] The above-mentioned rotating support member includes an annular guide rail and a rotating support ring. The annular guide rail is arranged on the adjustment seat and is coaxially arranged with the fixed shaft. The rotating support ring is sleeved on the annular guide rail and connected to the support.
[0009] The above-mentioned sliding seal includes a mounting ring and a sealing rubber ring. The mounting ring is welded to the lower end of the protective sleeve. The inner ring surface of the mounting ring is provided with an annular groove. The sealing rubber ring is embedded in the annular groove and the inner ring surface is in contact with the outside of the fixed sleeve.
[0010] The utility model provides a pipe rack support leg. It has the following beneficial effects: the pipe rack support leg is provided with a protective sleeve on the outside of the adjustment screw. When the height of the pipe rack needs to be adjusted, the adjustment seat on the upper end of the adjustment screw can be directly rotated. The rotation of the adjustment seat drives the adjustment screw to rotate. The adjustment screw moves upward or downward under the limiting action of the threaded seat, thereby pushing the support and the pipe rack to move in the vertical direction. The protective sleeve provided on the outside of the adjustment screw can effectively prevent contamination of the adjustment screw, thereby improving the stability and convenience of the support leg. In addition, the adjustment seat and the support adopt a rotational fit. Therefore, during the rotation of the adjustment seat and the adjustment screw, the support can still maintain the current posture and only changes in the height direction. Adjustment can be made without removing the oil pipe or unloading the load. The structure is simple, the operation is convenient, and the practicality is strong. BRIEF DESCRIPTION OF THE DRAWINGS
