Technical Field
[0001] This utility model relates to a tooling structure, and more particularly to a tooling structure applied to pipe connection, specifically a portable flange quick assembly device. Background Technology
[0002] Traditional pipe flange connection methods present several inconveniences. First, flange connection typically requires two operators working together: one to support the flange and the other to adjust and secure it. This collaborative approach is highly manpower-dependent. Second, to ensure the stability of the flange's relative position to the pipe during connection, spot welding is often required at the pipe end. This spot welding is not only inefficient and adds extra steps, but the high temperatures and welding stress generated during the process can easily damage the pipe material. This damage can lead to pipe corrosion, significantly impacting pipeline construction.
[0003] Therefore, improvements are urgently needed to better meet construction requirements. Utility Model Content

Detailed Implementation
[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0033] like Figures 1 to 9 As shown.
[0034] This utility model discloses a portable flange quick assembly device, comprising: a guide rod 7, a slider 2, a support plate 1, a support rod 5, a guide disc 4, a guide rod 6, and a guide extension rod 8, etc.
[0035] The guide rod 7 is a straight rod, divided into a left section and a right section in the middle, with threads in opposite directions on the left and right sections. A handwheel 3 is provided at one end of the guide rod 7 for easy rotation.
[0036] There are two sliders 2, both block-shaped, with screw holes along their axes to mate with the guide rod, allowing them to be screwed onto the left and right sections of the guide rod 7 respectively. The sliders 2 are symmetrical about the center line of the guide rod 7 and can move in opposite directions as the guide rod 7 rotates.
[0037] The support plate 1 is a long, flat plate, and there are four of them, evenly distributed around the guide rod 7 along its axial direction. The top surface of the support plate 1 is domed and faces away from the guide rod 7, which facilitates its fit against the inner wall of the pipe.
[0038] The support rod 5 is a straight rod, with its two ends hinged to the ends of the slider 2 and the support plate 1, respectively. Preferably, the slider 2 and the support plate 1 are each provided with a lug-shaped connecting block to facilitate hinged connection with the support rod.
[0039] The guide disk 4 is disc-shaped with a through-hole 403 at its center and multiple guide grooves 401 at the same position on both ends. The diameter of the mounting hole 403 is larger than the outer diameter of the guide rod 7, allowing the guide disk 4 to be movably fitted onto the guide rod 7 through the mounting hole 403 without rotating with the guide rod 7. The number of guide grooves 401 is the same as the number of support plates 1, arranged along the radial direction of the guide disk 4, and corresponding to the support plates 1. In this embodiment, there are four guide grooves arranged in a cross shape, and the guide grooves on both sides of the guide disk are in the same position, corresponding one-to-one.
[0040] The guide groove 401 is a straight groove with a cross-section in the shape of a cross. The guide rod 6 is a straight plate, with its distal end connected to the bottom surface of the support plate 1 and its proximal end suspended, making it perpendicular to the bottom surface of the support plate 1 and corresponding one-to-one with the guide groove 401. Furthermore, the guide rods 6 are arranged in pairs. The two guide rods 6 in each pair are parallel to each other and spaced apart, with the distance between them adapted to the thickness of the guide disc 4. Preferably, a stiffening plate 601 is also included. The stiffening plate 601 is triangular, with its two sides connected to the outer side of the guide rod 6 and the bottom surface of the support plate 1, respectively, to improve the support strength of the guide rod.
[0041] A limiting post 602 is provided at the suspended end of the guide rod 6. The limiting post 602 is a short cylinder, with one end connected to the guide rod 6 and the other end suspended. The height of the limiting post 602 is adapted to the depth of the guide groove 4, and its diameter is slightly smaller than the width of the guide groove 4, so that it can be movably embedded in the guide groove 4 and can move along the guide groove 4, ensuring that the guide rod 6 moves along the radial direction of the guide disc 4.
[0042] The guide extension rod 8 is a straight plate, its size adapted to the guide groove 4, and can be movably inserted into the guide groove 4. Simultaneously, the guide extension rod 8 has one main limiting groove 801 and two auxiliary limiting grooves 802 along its length. Both the main limiting groove 801 and the auxiliary limiting grooves 802 are elongated holes, parallel to each other and spaced apart, with the auxiliary limiting grooves 802 evenly located on both sides of the main limiting groove 801. The lengths of the main limiting groove 801 and the auxiliary limiting grooves 802 are approximately equal and slightly shorter than the length of the guide groove 4.
[0043] The suspended end of the limiting post 602 is provided with a "T"-shaped protrusion 6021. Simultaneously, the outer end of the main limiting groove 801 is provided with a circular connecting hole. The upper diameter of the protrusion 6021 is slightly smaller than the diameter of the connecting hole, and its lower end is smaller than the width of the main limiting groove 801, allowing the connecting hole to easily fit into the protrusion 6021 and enabling the main limiting groove 801 to move along the protrusion 6021.
[0044] A limiting pin 402 is provided on each side of the outer end of the guide groove 4. The diameter of the limiting pin 402 is smaller than the width of the auxiliary limiting groove 802, and it is placed in the auxiliary limiting groove 802 to prevent the guide extension rod 8 from being pulled out of the guide groove 4.
[0045] The method of using this utility model is as follows:
[0046] Rotate the handwheel to move the slider backward, bringing the support plate closer to the guide rod. Then, insert the device into the pipe port to about halfway up the support plate and rotate the handwheel to move the sliders towards each other, spreading the support plate closer to the inner wall of the pipe. When the support plate just touches the inner wall of the pipe, stop rotating the handwheel and attach the flange to the support plate, pressing it firmly against the pipe port. Finally, continue rotating the handwheel until the support plate is fully pressed against the inner wall of the pipe and the flange, completing the flange assembly operation. During this process, as the support plate moves outward, the limiting post on the guide rod moves along the guide groove. When the pipe diameter is large, the limiting post moves to the connecting hole at the outer end of the main limiting groove, gradually pulling the guide extension rod out of the guide groove.
[0047] After the flange assembly is completed, rotate the handwheel in the opposite direction to retract the support plate and detach it from the inner wall of the pipe. During this process, the guide rod and guide extension rod ensure that the support plate moves along the direction of the guide groove, preventing twisting.
[0048] This utility model has a simple structure, is easy to use, can be operated by a single person, and is easy to carry. It effectively solves the problems of low efficiency, the need for multiple people to cooperate, and damage to the pipe base material in the traditional flange connection process, creating favorable conditions for improving economic benefits.
[0049] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
