Description

Technical Field

[0001] This utility model relates to the field of mouthpiece technology, and more particularly to a combined multi-plate mouthpiece. Background Technology

[0002] A pipe alignment tool is a tool used during pipe installation and maintenance to ensure accurate connection and coaxiality between two pipe sections. It is widely used in pipeline projects in industries such as petroleum, natural gas, chemical, and power.

[0003] Pipe alignment tools belong to the field of welding auxiliary tools. They improve construction efficiency by reducing manual adjustment time and accelerating pipe installation. 2. They ensure project quality by guaranteeing the accuracy and stability of pipe connections and reducing stress concentration problems caused by misalignment. 3. They enhance safety by reducing the operational difficulty and risks for construction workers, especially in confined spaces. 4. They reduce costs by decreasing rework rates and material waste, indirectly lowering project costs.

[0004] The pipe alignment device disclosed in CN218904189U includes an adjusting rod, a first base, a second base, and multiple sets of movable tensioning mechanisms. Both the first and second bases are movably mounted on the adjusting rod, and at least one of them is driven to the adjusting rod. The multiple sets of movable tensioning mechanisms are arranged circumferentially around the adjusting rod and connected to the first and second bases. The outer contours of the multiple sets of movable tensioning mechanisms form a tensioning profile for a predetermined pipe, and the tensioning profile is coaxial with the adjusting rod. The adjusting rod can drive the first and second bases to move closer or further apart, thereby causing the tensioning profile to coaxially enlarge or shrink. Its advantage is that it eliminates the need for a fixed connection with the pipe; instead, it limits its relative position to the pipe through tension. A single clamping operation can form an overall tensioning profile, thus facilitating the assembly and disassembly of the device and greatly improving the efficiency of the entire pipe alignment process.

[0005] The equipment in the above technical solution requires workers to make adjustments inside the pipeline, which is not conducive to the use of long pipelines. Workers cannot make adjustments at one end of the pipeline, so improvements are needed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a combined multi-plate matching device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A combined multi-piece matching device includes an inner support, a lifting mechanism on the inner support, an outer support on the lifting mechanism, and the outer support is slidably mounted on the inner support. The lower end of the inner support has openings on both sides, and a cylindrical pin passes through the lower end of the outer support. The cylindrical pin passes through the two openings on both sides of the lower end of the inner support.

[0009] Multiple tension plates are evenly spaced through the cylindrical pin, and all tension plates are located inside the inner bracket.

[0010] A magnet is detachably connected to one side of the lower end of the inner support, and the lower end of the magnet is flush with the lower end of the inner support.

[0011] Compared with the prior art, this application can stably adjust the position and height of the inner support relative to the outer support, and can ensure the stable lifting and lowering of the inner support relative to the outer support. It can quickly press down the inner support so that the tension plate and the inner support can respectively abut against the two sides of the pipe. By distributing multiple of these devices at equal intervals around the circumference of the pipe, it helps to achieve full alignment.

[0012] Preferably, the lifting mechanism includes an internal hexagon bolt threaded onto the outer bracket, with the lower end of the internal hexagon bolt rotatably fitted onto the upper middle part of the inner bracket.

[0013] Furthermore, by rotating the hexagon socket head cap screw and controlling the direction of rotation of the hexagon socket head cap screw, the inner support can be lifted and lowered within the outer support, and the positional relationship between the lower end of the inner support and the tension plate can be controlled.

[0014] Preferably, the upper end of the inner support is provided with sliding grooves on both sides, and a sliding plate is slidably sleeved in the sliding groove. The two sliding plates are respectively fixed on the opposite side walls inside the outer support, and the two sliding plates and the outer support are integrally formed.

[0015] Furthermore, by controlling the positional relationship between the slide plate and the slide rail, the inner support can be effectively limited to moving up and down relative to the outer support.

[0016] Preferably, the magnet abuts against the lower end of the inner bracket, and two connecting bolts are threaded through the magnet and threaded into the inner bracket.

[0017] Furthermore, the connecting bolts allow for quick and secure connection of the magnets to the inner support, effectively ensuring the strength of the connection.

[0018] The beneficial effects of this utility model are:

[0019] 1. This mouth-aligning device is lightweight, small in size, and easy to carry; compared with conventional mouth-aligning devices, it is more convenient to use in scenarios with limited space.

[0020] 2. Because the thickness of the tension plate and the width of the contact surface with the pipe are designed to match the gap size at the root of the pipe welding, during the pipe alignment process, the combined multi-plate alignment device is placed after the fixed pipe, and the tension plate is attached to one side of the fixed pipe end face; the other moving pipe end face can directly press against the other side of the tension plate, which directly eliminates the problem of adjusting the root gap distance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-5The combined multi-piece alignment device includes an inner support 3. In actual production, one side of the lower end of the inner support 3 is chamfered to facilitate movement, while the other side is not chamfered and has corresponding connecting holes. These holes are used to connect the inner support 3 to a magnet 9 via connecting bolts 10. The inner support 3 is equipped with a lifting mechanism, which in turn is equipped with an outer support 8. The lifting mechanism includes a hexagonal socket head cap screw 7 threaded onto the outer support 8. The lower end of the hexagonal socket head cap screw 7 is rotatably fitted onto the upper middle part of the inner support 3. Operators can control the rotation and direction of the hexagonal socket head cap screw 7, enabling it to lift and lower the inner support 3. The hexagonal socket head cap screw 7 lifts and lowers the inner support 3 relative to the tension plate 1, allowing the inner support 3 and the tension plate 1 to contact the inner and outer walls of the pipe, thus aligning the pipe at that position. Furthermore, by aligning the two pipes at multiple points on opposite ends, alignment of the two pipes at opposite ends is achieved, facilitating subsequent operations.

[0029] Reference Figure 1-3 The outer support 8 is slidably mounted on the inner support 3. The upper end of the inner support 3 is provided with grooves 5 on both sides. Slide plates 6 are slidably sleeved in the grooves 5. The two slide plates 6 are fixed on the opposite side walls inside the outer support 8. The two slide plates 6 and the outer support 8 are integrally formed. In actual production, the grooves 5 are set through the upper end of the opening 4, which can facilitate the control of the inner support 3 to move in the direction of the tension plate 1. Furthermore, the slide plates 6 can fully realize the smooth relative lifting between the outer support 8 and the inner support 3. The integral forming facilitates production.

[0030] Reference Figure 1-4 The inner support 3 has openings 4 on both sides of its lower end, and the lower end of the outer support 8 is provided with a cylindrical pin 2. In use, the cylindrical pin 2 can pass through the outer support 8 and the inner support 3, and the cylindrical pin 2 passes through the opening 4 and the tension piece 1, which can effectively limit the position of the tension piece 1. The cylindrical pin 2 is set in the two openings 4 on both sides of the lower end of the inner support 3; it can effectively limit the position of the cylindrical pin 2, so as to effectively limit the position relationship of the tension piece 1.

[0031] Reference Figure 1-4 Multiple tension plates 1 are evenly spaced through the cylindrical pin 2, and all tension plates 1 are located inside the inner bracket 3. A magnet 9 is detachably connected to one side of the lower end of the inner bracket 3. The lower end of the magnet 9 is flush with the lower end of the inner bracket 3, which can effectively attract the magnet. The magnet 9 abuts against one side of the lower end of the inner bracket 3. Two connecting bolts 10 are threaded through the magnet 9. One end of the connecting bolt 10 is threaded into the inner bracket 3. The connecting bolts 10 can connect and fix the magnet 9 and the inner bracket 3.

[0032] In this utility model, when two pipes are welded together during construction, one end of the pipe is a fixed end, and the other end, which is the moving end, is where the engineering equipment is hoisted.

[0033] Place the assembled multi-piece matching device on the outer circle of the fixed end pipe near the welding end face. The magnet 9 on the device will attract it. Then, move the tension piece 1 to be perpendicular to the inside of the pipe and stick it to the pipe end face. Place three or more pieces above the outer circle of the pipe end face in sequence to ensure uniform tension in subsequent work and facilitate pipe matching.

[0034] The pipe to be welded is lifted and moved evenly to the fixed pipe end face until it is fully aligned with the side of the tension plate of the connector and completely tightened.

[0035] Adjust the hexagonal bolts 7 on these alignment tools to make the inner support 3 and tension plate 1 contact the outer and inner walls of the pipes, aligning the two pipes. Check and increase tension to correct the alignment. After confirming there are no problems, have the welder perform argon arc welding to intermittently weld several sections. Then, pull out the cylindrical pin 2 on the alignment tool and remove the outer support 8 and inner support 3. Next, rotate the tension plate 1 180° between the two pipe end faces and pull it out. The alignment is complete, and then perform the complete pipe welding.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
