Description

Technical Field

[0001] This utility model relates to support devices, and in particular to a drilling and positioning support device for petrochemical pipelines. Background Technology

[0002] In many industrial sectors such as petroleum and chemical engineering, as well as in municipal engineering construction, it is often necessary to drill holes in pipelines to install branch pipes, instrumentation devices, and other ancillary facilities.

[0003] Currently, the main problems encountered when drilling holes in pipelines are as follows:

[0004] 1. When drilling holes in pipes, there is a lack of reliable and convenient fixing devices to stably place the pipe drilling machine. Traditional methods often involve temporarily erecting simple support structures or placing the drilling machine directly on the pipe and supporting it manually. This not only makes it difficult to ensure the stability of the drilling machine during the drilling process, easily leading to drilling position deviations and affecting subsequent installation work, but also increases the labor intensity of operators and poses significant safety hazards.

[0005] 2. Existing methods for securing pipes also have shortcomings. Common methods involve using simple tools such as ropes and clamps, but these methods cannot be flexibly adjusted for pipes of different diameters and materials, resulting in poor applicability. Furthermore, during drilling, factors such as vibration from the drilling machine make it difficult to ensure the pipe remains stable, potentially causing pipe displacement and hindering drilling operations, thus reducing efficiency and quality.

[0006] 3. In some large-scale engineering projects or field operations, the site conditions are complex and varied, placing higher demands on the fixation of drilling equipment and the stability of pipelines. However, existing fixing and support devices are insufficient to meet the needs of these complex working conditions, making it impossible to complete pipeline drilling tasks quickly and efficiently, thus hindering project progress. Summary of the Invention

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a support device that is fast to construct, recyclable, height adjustable, tightness and position adjustable, and adaptable to pipes of different diameters.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] This utility model discloses a drilling and positioning support device for petrochemical pipelines, comprising a support plate. Two steel plates are welded to the lower side of one of the short sides of the support plate, symmetrically distributed and inclined inward at their lower ends to form a V-shaped structure. A nut is welded at the intersection of the V-shaped structure on one side, with the central axis of the nut parallel to the horizontal plane of the support plate. A screw threadedly engages with the nut. An arc-shaped clamping block is welded to the inner side of the lower end of the V-shaped structure on the other side, with the top of the arc-shaped clamping block welded to the bottom wall of the support plate. Multiple rows of support plate bolt connection holes are formed on the top wall of the support plate, and an installation groove is placed therein. Installation groove bolt connection holes are formed at the four corners of the bottom surface of the installation groove. The installation groove can be fixedly connected to the support plate at a set position by bolts passing through the support plate bolt connection holes and the installation groove bolt connection holes. A magnet is installed on the bottom and top wall of the installation groove. The drilling machine base is placed in the installation groove and can be attracted and fixed by the magnet.

[0010] The beneficial effects of this utility model are:

[0011] (1) High adaptability: The arc-shaped clamp can be adapted to various pipe diameters by adjusting the screw, and the bearing plate mounting groove can be adapted to different models of drilling machines. It has high versatility and reduces equipment investment costs.

[0012] (2) Fixed and stable: The combination of mechanical clamping and limiting effectively prevents the equipment from sliding during drilling, improves drilling accuracy, reduces the generation of waste holes and deviation holes, and ensures the quality of pipeline processing.

[0013] (3) Easy to operate: The pipe can be quickly clamped by turning the adjustment screw with the handle. The position of the punching machine is easy to adjust, which reduces the difficulty of operation for workers, shortens the preparation time, and improves the processing efficiency.

[0014] (4) Excellent safety protection: The equipment provides rigid connection support between the drilling machine and the pipeline, replacing manual hand support or simple binding and fixing methods, avoiding accidental displacement or falling of the equipment during drilling and reducing the risk of operation safety.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] As shown in the attached diagram, this utility model discloses a drilling and positioning support device for petrochemical pipelines, comprising a support plate 3, preferably rectangular. Two steel plates 4 are welded to the lower side of one of the short sides of the support plate 3. The two steel plates are symmetrically distributed, with their lower ends inclined inward to form a V-shaped structure. Preferably, the included angle between the two steel plates is 60 degrees. A nut 5 is welded at the intersection of the V-shaped structure on one side. The central axis of the nut 5 is parallel to the horizontal plane of the support plate 3. A screw 1 is threaded into the nut, and the screw 1 is used to adjust the tightness with the pipeline by rotating the nut 5. An arc-shaped clamping block 2 is welded to the inner side of the lower end of the V-shaped structure on the other side. The top of the arc-shaped clamping block 2 is welded to the bottom wall of the support plate 3. Preferably, a 3-5mm thick rubber anti-slip pad is pasted on the inner wall of the arc-shaped clamping block 2 to effectively enhance the friction with the pipeline surface and prevent slippage during operation.

[0019] Multiple rows of bearing plate bolt connection holes are formed on the top wall of the bearing plate 3, and a mounting groove 6 is placed there. Mounting groove bolt connection holes are formed at the four corners of the bottom surface of the mounting groove. The mounting groove can be fixedly connected to the bearing plate at a set position by bolts passing through the bearing plate bolt connection holes and the mounting groove bolt connection holes. Magnets are installed on the top wall of the bottom of the mounting groove. The drilling machine base is placed in the mounting groove and can be attracted and fixed by the magnets. During installation, high-strength bolts are passed through the bearing plate bolts and the mounting groove bolt connection holes to connect the bearing plate to the adjustable mounting groove 6. After adjusting the position of the drilling machine, tightening the bolts will firmly fix the drilling machine, ensuring that the equipment will not shift during the drilling process.

[0020] The procedure for using this device is as follows:

[0021] First, the petrochemical pipeline drilling and positioning support device is placed stably above the pipeline to be drilled, so that the V-shaped support structure and the arc-shaped clamp 2 correspond to the two sides of the pipeline respectively. At this time, the operator holds the rotating handle at the end of the adjusting screw 1 and rotates the adjusting screw 1 clockwise. Since the adjusting screw 1 and the nut 5 in the middle of the V-shaped structure form a threaded engagement, under the action of the thread transmission, the adjusting screw 1 will extend downward along the direction parallel to the bearing plate 3, gradually approaching the surface of the pipeline.

[0022] As the adjusting screw 1 continues to extend, its bottom end will contact the outer wall of the pipe. Continue to turn the handle to tighten the screw against the pipe until you feel significant resistance. At this point, the arc-shaped clamp 2 will also fit tightly against the outer wall of the other side of the pipe under the reaction force. Then, the adjusting screw 1 is mechanically locked by the nut 5. The spot-welded structure of the nut 5 and the strip steel plate 4 forms a fixed fulcrum. After tightening, the friction between the threads can be used to limit the reverse rotation of the screw, thereby firmly fixing the entire device and the subsequently installed drilling machine to the pipe. With the help of the V-shaped support, the friction between the arc-shaped clamp and the pipe surface, and the mechanical limiting effect of the adjusting screw, the equipment slippage caused by vibration during operation is effectively prevented.

[0023] According to the pre-marked pipe drilling positions, the operator places the drilling machine stably on the support plate 3 and adjusts the lateral position of the drilling machine using the sliding mounting groove 6 and the drilling machine itself. After the central axis of the drilling machine bit is precisely aligned with the pipe drilling mark, the high-strength bolts that pass through the connecting hole of the drilling machine base and the mounting groove are tightened with a wrench to form a rigid connection between the drilling machine and the support plate 3, ensuring that the radial displacement of the drill bit is controlled within 0.5mm during the drilling process.

[0024] After preparation, the operator starts the drilling machine according to safety procedures. Once the drill bit reaches its rated speed, the feed pressure is slowly applied downwards. Simultaneously, the rubber anti-slip pad on the inner side of the arc-shaped clamping block 2 further absorbs vibration energy, reducing the impact of resonance on drilling accuracy.

[0025] After the drill bit has completely penetrated the pipe wall, first turn off the drilling machine. Once the drill bit stops rotating, rotate the handle in the opposite direction to remove the drill bit from the hole. Then, the operator uses a wrench to loosen the bolts securing the drilling machine, remove the drilling machine from the support plate 3, and then rotate the handle of the adjusting screw 1 counterclockwise. At this point, the locking state between the nut 5 and the screw is released, and the screw gradually retracts, disengaging from the pipe surface. The arc-shaped clamp 2 also loosens accordingly. Finally, remove the entire device from the pipe and move it to the next drilling point. Repeating the above operations will complete the continuous drilling operation.
