A triangular support tool for fixing the upper part of a well casing

Abstract

This utility model relates to the field of well construction technology, specifically a triangular support tool for fixing the upper part of a well pipe. It includes a column, a crossbeam welded to the top of the column, a diagonal rod welded between the end of the crossbeam furthest from the column and the bottom of the column, a sliding sleeve slidably fitted onto the outer surface of the column, a screw welded to the side of the sliding sleeve furthest from the diagonal rod, a clamping plate slidably fitted onto the surface of the screw, and a nut threaded onto the outer surface of the screw. The advantage is that by evenly inserting three of these tools into the gap between the well pipe and the well hole, the column rests against the outer wall of the well pipe, the diagonal rod rests against the top of the well hole, and then tightening the nut clamps the clamping plate against the inner wall of the well pipe, thus fixing the top of the well pipe. This prevents the top of the well pipe from tilting after impact, allowing for rapid pouring of filter material into the gap between the well pipe and the well hole, improving construction efficiency.

Description

Technical Field

[0001] This utility model relates to the field of well construction technology, and in particular to a triangular support tool for fixing the upper part of the well pipe. Background Technology

[0002] During well construction, after drilling the well hole, the well casing is lowered into the hole. Then, filter material needs to be filled into the gap between the well casing and the well hole. When filling the gap, a small hole is usually made in the rear door of the transport vehicle, allowing the filter material to slowly flow into the gap between the well casing and the well hole.

[0003] However, since there is no fixed structure at the top of the well pipe, if the filter material is poured too quickly, it will hit the top of the well pipe, causing the well pipe to tilt and shift. This will result in uneven distribution of the filter material around the well pipe. On the side with less filter material, the filtration of impurities will be insufficient. Therefore, to ensure the normal use of the well, it is not advisable to pour the material too quickly, which would lead to slow construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0005] Therefore, one objective of this utility model is to provide a triangular support tool for fixing the upper part of the well pipe, which aims to solve the problem of slow construction efficiency during the pouring of filter material in existing well construction.

[0006] To achieve the above objectives, one embodiment of the present invention provides a triangular support tool for fixing the upper part of a well pipe, including a column, a crossbeam welded and fixed to the top of the column, a diagonal rod welded and fixed between the end of the crossbeam away from the column and the bottom end of the column, a sliding sleeve slidably fitted onto the outer surface of the column, a screw rod welded and fixed to the side of the sliding sleeve away from the diagonal rod, a clamping plate slidably fitted onto the surface of the screw rod, and a nut threadedly connected to the outer surface of the screw rod.

[0007] The beneficial effects are as follows: When using this tool, at least three of these tools should be used as a set. The three tools should be evenly arranged and inserted into the gap between the well pipe and the well hole, so that the column abuts against the outer wall of the well pipe and the diagonal rod abuts against the top of the well hole. Then tighten the nut to clamp the clamping plate against the inner wall of the well pipe, thereby fixing the top of the well pipe. This makes it less likely for the top of the well pipe to tilt after being impacted. As a result, when filling the filter material, the filter material can be quickly poured into the gap between the well pipe and the well hole, thereby improving construction efficiency.

[0008] A preferred embodiment is that the sliding sleeve is provided with two screws.

[0009] The beneficial effects are as follows: based on the principle that two points determine a straight line, two screws are fixed to a pair of clamps, and the clamps will not rotate relative to the column, thus ensuring that the tool will not rotate during use, thereby improving the reliability of fixing the well casing.

[0010] In a preferred embodiment, a reinforcing rod is welded and fixed between the column and the diagonal brace, and a notch is provided on one side of the sliding sleeve.

[0011] The beneficial effects are: the reinforcing rod can strengthen the diagonal rod, avoiding the problem of the diagonal rod tilting under force during the support process, and the notch can allow the sliding sleeve to slide normally up and down without being affected by the reinforcing rod.

[0012] In a preferred embodiment, a cover plate is fixedly installed on the top of the clamping plate.

[0013] Furthermore, the top of the cover plate has multiple slots, and the top of the clamping plate is welded and fixed with a screw rod II. The multiple slots on the cover plate are respectively fitted onto the screw rod II on the top of the clamping plates, and the outer surface of the screw rod II is threaded with a nut II.

[0014] The beneficial effects are as follows: the cover plate shields the top of the well pipe, so that during the rapid filling process, the filter material falls onto the cover plate and, after accumulating to a certain amount, will flow to the surroundings and fall into the gap between the well pipe and the well hole, thus avoiding the problem of filter material falling into the well pipe during the rapid filling process.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides a triangular support tool for fixing the upper part of a well pipe.

[0026] Example 1:

[0027] like Figure 1 As shown, it includes a column 1, a sliding sleeve 2 that is slidably fitted on the outer surface of the column 1, and a crossbeam 11 that is welded and fixed at the top of the column 1. A diagonal rod 12 is welded and fixed between the end of the crossbeam 11 away from the column 1 and the bottom end of the column 1. Two screw rods 21 are welded and fixed on the side of the sliding sleeve 2 away from the diagonal rod 12. A clamping plate 22 is slidably fitted on the surface of the two screw rods 21, and nuts 23 are threaded onto the outer surface of both screw rods 21.

[0028] A reinforcing rod 13 is welded and fixed between the column 1 and the diagonal rod 12. During use, the diagonal rod 12 is reinforced to prevent it from deforming under stress. A notch 24 is provided on one side of the sliding sleeve 2. When the sliding sleeve 2 slides up and down on the surface of the column 1, the reinforcing rod 13 can pass through the notch 24 without affecting the sliding of the sliding sleeve 2.

[0029] The working principle of this embodiment is as follows: When in use, the tool is used in groups of at least three; this application uses three as an example. Figure 2As shown, after the well pipe 4 is placed into the well hole 3, three tools are evenly inserted into the gap between the well pipe 4 and the well hole 3, so that the column 1 abuts against the outer wall of the well pipe 4 and the diagonal rod 12 abuts against the top of the well hole 3. Then, the nut 23 is tightened so that the clamping plate 22 is clamped against the inner wall of the well pipe 4. Thus, the three tools fix the top of the well pipe 4, so that the top of the well pipe 4 is not easily tilted when it is hit.

[0030] Example 2:

[0031] like Figure 3-5 As shown, based on Embodiment 1, it also includes a cover plate 5. The top of the cover plate 5 has multiple slots 51. The top of the clamping plate 22 is welded and fixed with screw rods 25. The multiple slots 51 on the cover plate 5 are respectively fitted onto the screw rods 25 on the top of the clamping plates 22. Then, nuts 26 are threaded onto the screw rods 25 to position the cover plate 5. Thus, the cover plate 5 covers the top of the well pipe 4. When filter material is quickly poured into the gap between the outer wall of the well pipe 4 and the inner wall of the well hole 3, it can prevent the filter material from falling into the well pipe 4.
