Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe alignment clamp technology, and in particular to a pipe alignment device. Background Technology
[0002] Pipe alignment clamps are tools used to ensure that two pipes can be precisely aligned when connected. Pipe alignment clamps play a key role in pipe installation, maintenance and welding, especially in situations requiring high-precision pipe connections, such as power plant boilers, oil, natural gas and chemical industries.
[0003] The main function of pipe alignment clamps is to fix and align the two pipe ends to be connected, ensuring that the two pipes are in the correct position during welding or connection. However, existing pipe alignment clamps rely on manual judgment of alignment accuracy during use, which can easily lead to misalignment, skewness, and other problems, resulting in poor connections. Utility Model Content
[0004] The purpose of this utility model is to provide a pipe alignment device that can solve the problem of poor connection caused by misalignment or skewness during the alignment process of existing pipe alignment clamps.
[0005] This utility model provides a pipe alignment device, including a controller panel, a first clamping arm, and a second clamping arm. The first clamping arm and the second clamping arm are arranged opposite to each other. Three through-beam photoelectric sensor transmitters are installed on the outer periphery of the first clamping arm, and three through-beam photoelectric sensor receivers are installed on the outer periphery of the second clamping arm. The three through-beam photoelectric sensor transmitters and the three through-beam photoelectric sensor receivers are in one-to-one correspondence and are respectively connected to the controller panel. When the axes of the first clamping arm and the second clamping arm coincide, the light beams emitted by the three through-beam photoelectric sensor transmitters can be just received by the three through-beam photoelectric sensor receivers, at which time the first clamping arm and the second clamping arm are aligned.
[0006] According to the present invention, a pipe fitting device is provided, wherein the first clamping arm includes a first cylindrical body and a first pipe clamping mechanism disposed inside the first cylindrical body, and the second clamping arm includes a second cylindrical body and a second pipe clamping mechanism disposed inside the second cylindrical body.
[0007] According to the pipe alignment device provided by this utility model, two through-beam photoelectric sensor transmitters are installed on the outer walls of the left and right sides of the first cylindrical body.
[0008] According to the pipe alignment device provided by this utility model, a first fixing ring is installed at the middle position of the outer wall of the first cylindrical body, and a through-beam photoelectric sensor transmitter is installed at the upper end of the first fixing ring.
[0009] According to the pipe alignment device provided by this utility model, two of the above-mentioned through-beam photoelectric sensor receivers are installed on the outer walls of the left and right sides of the second cylindrical body.
[0010] According to the pipe alignment device provided by this utility model, a second fixing ring is installed at the middle position of the outer wall of the second cylindrical body, and a through-beam photoelectric sensor receiver is installed at the upper end of the second fixing ring.
[0011] According to the pipe alignment device provided by this utility model, two first support blocks are installed at the bottom of the first clamping arm, and the two first support blocks are respectively spaced apart along the length direction of the first clamping arm; two second support blocks are installed at the bottom of the second clamping arm, and the two second support blocks are respectively spaced apart along the length direction of the second clamping arm.
[0012] According to the pipe alignment device provided by this utility model, a first lifting device is installed and fixed at the bottom of each of the first clamping arms, and a second lifting device is installed and fixed at the bottom of each of the second clamping arms.
[0013] According to the present invention, a pipe alignment device further includes a base, and the first lifting device, the second lifting device and the controller panel are respectively mounted on the base.
[0014] According to the present invention, a pipe alignment device is provided, wherein the controller panel is provided with a display screen and control buttons.
[0015] The pipe alignment device provided by this utility model features three through-beam photoelectric sensor transmitters mounted on the outer periphery of the first clamping arm and three through-beam photoelectric sensor receivers mounted on the outer periphery of the second clamping arm. These transmitters and receivers are aligned in a one-to-one correspondence and are connected to a controller panel. When the axes of the first and second clamping arms coincide, the light beams emitted by the three transmitters are precisely received by the three receivers, indicating alignment between the first and second clamping arms. This pipe alignment device, by employing the structure of three through-beam photoelectric sensor transmitters and receivers, and determining alignment by whether the receivers receive the emitted light beams, effectively solves the misalignment and skew problems that easily occur when relying on manual judgment of alignment accuracy in traditional methods. This significantly improves pipe alignment accuracy and the quality of pipe alignment connections. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" 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; 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 based on the specific circumstances.
[0027] like Figure 1 and Figure 2 As shown, the pipe alignment device of this utility model embodiment includes a controller panel 1, a first clamping arm 2, and a second clamping arm 3. The first clamping arm 2 and the second clamping arm 3 are arranged opposite to each other. Three through-beam photoelectric sensor transmitters 4 are installed on the outer periphery of the first clamping arm 2, and three through-beam photoelectric sensor receivers 5 are installed on the outer periphery of the second clamping arm 3. The three through-beam photoelectric sensor transmitters 4 and the three through-beam photoelectric sensor receivers 5 are in one-to-one correspondence and cooperation, and each through-beam photoelectric sensor transmitter 4 and each through-beam photoelectric sensor receiver 5 is respectively signal connected to the controller panel 1.
[0028] When the axes of the first clamping arm 2 and the second clamping arm 3 coincide, the beams emitted by the three through-beam photoelectric sensor transmitters 4 can be received by the three through-beam photoelectric sensor receivers 5, at which point the first clamping arm 2 and the second clamping arm 3 are aligned.
[0029] In other words, during use, the first clamping arm 2 and the second clamping arm 3 clamp the two pipe ports to be connected, respectively. Then, the controller panel 1 controls the operation of three sets of through-beam photoelectric sensors. Specifically, the controller panel 1 can control the three through-beam photoelectric sensor transmitters 4 to emit light beams, and the three through-beam photoelectric sensor receivers 5 can respectively feed back signals of receiving light beams to the controller panel 1. If all three through-beam photoelectric sensor receivers 5 receive the emitted light beam, the controller panel 1 can determine that the first clamping arm 2 and the second clamping arm 3 are aligned. If any one of the through-beam photoelectric sensor receivers 5 does not receive the emitted light beam, the controller panel 1 determines that the first clamping arm 2 and the second clamping arm 3 are not aligned, and the positions of the first clamping arm 2 and the second clamping arm 3 need to be adjusted until all three through-beam photoelectric sensor receivers 5 can receive the emitted light beam.
[0030] Therefore, the pipe alignment device of this utility model embodiment can determine whether the first clamping arm 2 and the second clamping arm 3 are aligned by using the cooperative structure of three through-beam photoelectric sensor transmitters 4 and three through-beam photoelectric sensor receivers 5, and by whether the three through-beam photoelectric sensor receivers 5 receive the emitted beam. This effectively solves the misalignment and skew problems that are easy to occur when relying on manual judgment of alignment accuracy in the traditional way, and effectively improves the pipe alignment accuracy and the quality of pipe alignment connection.
[0031] Specifically, the controller panel 1 is equipped with a display screen 101 and control buttons 102.
[0032] Specifically, the first clamping arm 2 includes a first cylindrical body 201 and a first pipe clamping mechanism (not shown in the figure) disposed inside the first cylindrical body 201. The second clamping arm 3 includes a second cylindrical body 301 and a second pipe clamping mechanism (not shown in the figure) disposed inside the second cylindrical body 301. The first and second pipe clamping mechanisms are used to clamp and fix the pipe. Since both the first and second pipe clamping mechanisms in this embodiment adopt existing structural forms, their specific structures will not be described in detail, as long as they can reliably clamp the pipe.
[0033] Two through-beam photoelectric sensor transmitters 4 are installed on the outer walls of the left and right sides of the first cylindrical body 201. A first fixing ring 202 is installed at the middle position of the outer wall of the first cylindrical body 201, and a through-beam photoelectric sensor transmitter 4 is installed at the top of the first fixing ring 202.
[0034] Two through-beam photoelectric sensor receivers 5 are installed on the outer walls of the left and right sides of the second cylindrical body 301. A second fixing ring 302 is installed at the middle position of the outer wall of the second cylindrical body 301, and a through-beam photoelectric sensor receiver 5 is installed at the upper end of the second fixing ring 302.
[0035] Specifically, two first support blocks 6 are installed at the bottom of the first clamping arm 2, and the two first support blocks 6 are spaced apart along the length of the first clamping arm 2. The two first support blocks 6 provide reliable support for the first clamping arm 2. Two second support blocks 7 are installed at the bottom of the second clamping arm 3, and the two second support blocks 7 are spaced apart along the length of the second clamping arm 3. The two second support blocks 7 provide reliable support for the second clamping arm 3.
[0036] A first lifting device 8 is installed and fixed at the bottom of each first clamping arm 2, and a second lifting device 9 is installed and fixed at the bottom of each second clamping arm 3. The first lifting device 8 is used to make fine adjustments to the vertical direction of the first clamping arm 2, and the second lifting device 9 is used to make fine adjustments to the vertical direction of the second clamping arm 3. The working status of the first lifting device 8 and the second lifting device 9 can be controlled by the controller panel 1.
[0037] In this embodiment, both the first lifting device 8 and the second lifting device 9 adopt existing lifting drive devices, so their specific structures will not be described in detail. As long as reliable lifting and lowering adjustment of the first clamping arm 2 and the second clamping arm 3 can be achieved.
[0038] In addition, in order to achieve fine adjustment of the front and rear positions of the first clamping arm 2 and the second clamping arm 3, a first front and rear moving device (not shown in the figure) and a second front and rear moving device (not shown in the figure) can be set. The first lifting device 8 is installed on the first front and rear moving device, and the second lifting device 9 is installed on the second front and rear moving device. The working status of the first front and rear moving device and the second front and rear moving device can be controlled by the controller panel 1 respectively.
[0039] The first and second forward and backward moving devices both adopt existing horizontal displacement drive devices, so their specific structures and installation methods will not be described in detail. As long as reliable forward and backward position adjustment of the first clamping arm 2 and the second clamping arm 3 can be achieved.
[0040] Specifically, the pipe alignment device also includes a base 10, and a first forward and backward moving device, a second forward and backward moving device, and a controller panel 1 are respectively installed on the base 10.
[0041] In addition, a laser rangefinder 11 can be installed on the first support block 6 near the second clamping arm 3 to measure the distance between the adjacent first support block 6 and the second support block 7, thereby obtaining the distance between the first clamping arm 2 and the second clamping arm 3, and the measurement result can be fed back to the controller panel 1.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
