[0041] For the convenience of those skilled in the art to understand, the following further describes the present utility model with reference to the accompanying drawings.

[0042] Please refer to Figure 1 、 Figure 2 , which is an embodiment of a pipe alignment device provided by the present utility model, including a base support mechanism 1, a main length adjustment mechanism 2 and a flange adjustment mechanism 3. The main length adjustment mechanism 2 and the flange adjustment mechanism 3 are both arranged on the base support mechanism 1. The connecting pipe is composed of two flanges 5 and a pipe 4, and the two flanges 5 are located at both ends of the pipe 4; the flange adjustment mechanism 3 supports and positions the flange 5, and the pipe 4 is placed on the base support mechanism 1; according to the overall length of the pipe 4 and the flange 5, the position of the flange 5 can be adjusted through the flange adjustment mechanism 3 to achieve rapid and high-precision positioning of the pipe 4 and the flange 5.

[0043] Please refer to Figure 3 , the base support mechanism 1 includes a base 101, a support plate 102, a lifting lug 103 and a stop block 104; the base 101 is at the bottom of the whole device to provide stable support; multiple support legs can be arranged on the lower side of the base 101, or, according to actual use needs, the base 101 can be fixedly installed on the frame.

[0044] The support plate 102 is used to support the pipeline 4; the number of the support plates 102 can be set according to the usage needs, for example, two; the two support plates 102 are arranged in parallel and at intervals on the base 101, and a pipeline support groove 105 is formed at the upper end of the support plate 102. The pipeline support groove 105 is a V-shaped groove, which is suitable for products with a circular cross-section; the pipeline support grooves 105 of the two support plates 102 correspond to each other, so that the pipeline 4 is horizontal. The support plate 102 is connected to the base 101 through a connecting seat 106; the connecting seat 106 can be directly fixed on the base 101, and the two are fixed by welding; alternatively, the connecting seat 106 and the base 101 can be detachably connected. For example, the connection is realized through a bolt-nut assembly. At this time, multiple groups of bolt holes can be correspondingly arranged on the base 101, and the multiple groups of bolt holes are evenly distributed in the length direction of the base 101. In this way, the distance between the two support plates 102 can be adjusted to achieve the best support and positioning effects. Or, the connecting seat 106 is slidably installed on the base 101. At this time, the upper side of the base 101 is partially concave to form a guide groove, and the connecting seat 106 is slidably arranged in the guide groove. Whether the connecting seat 106 and the base 101 adopt a welding fixed manner, a detachable connection manner or a sliding connection manner, they are all conventional connection manners, so the corresponding structures are not shown in the drawings.

[0045] Preferably, a telescopic driving member (not shown in the figure) can also be arranged between the support plate 102 and the connecting seat 106 to realize the adjustment of the height of the support plate 102; the telescopic driving member can be a conventional driving element such as a cylinder, a hydraulic cylinder or a lead screw.

[0046] The lifting lugs 103 are installed on the base 101, and the number of the lifting lugs 103 can be set according to the usage needs; for example, Figure 2 as shown, the number of the lifting lugs 103 is four, and the four lifting lugs 103 are symmetrically and fixedly installed on the base 101; lifting and handling are convenient and flexible through the lifting lugs 103.

[0047] The stoppers 104 are arranged at both ends in the length direction of the base 101, and the number is at least two, which cooperate with the main length adjustment mechanism 2 to prevent the main length adjustment mechanism 2 from sliding out of the base 101 during adjustment.

[0048] Please refer to Figure 4, the main length adjustment mechanism 2 includes a first guide rail 201 and a support base 202. The support base 202 is slidably arranged on the first guide rail 201.

The length of the first guide rail 201 is not greater than the length of the base 101, and the base 101 can well support the first guide rail 201; a first slider 205 is provided at the position corresponding to the first guide rail 201 on the support base 202, and the position and size of the first slider 205 match those of the first guide rail 201. For example, the first guide rail 201 is a dovetail guide rail, and the first slider 205 has a dovetail groove. After the two are slidably connected, the first slider 205 can only slide along the first guide rail 201, and the stop block 104 can block the two ends of the first guide rail 201 to prevent the first slider 205 from detaching from the first guide rail 201.

[0049] The support base 202 can be manually adjusted or automatically adjusted by a driving device. For example, the support base 202 is driven by a servo motor and a lead screw. The flange adjustment mechanism 3 is arranged on the support base 202 and moves with the movement of the support base 202. The flange adjustment mechanism 3 can be slidably adjusted according to the length of the connecting pipe, so as to pair different lengths of connecting pipes. If the number of support bases 202 is one, the flange 5 on one side can be paired and welded and fixed, and then the flange 5 on the other side can be paired and welded; preferably, the number of support bases 202 is two, and a flange adjustment mechanism 3 is arranged on each support base 202 to support the flanges 5 at both ends of the pipe 4 respectively; the connection of the two flanges 5 can be completed by one pairing, improving the production efficiency.
