[0002] Modern industrial equipment often includes complex piping systems for oil, gas, and water, all secured by pipe fixtures. As industrial equipment becomes increasingly complex, higher requirements are placed on the rationality and aesthetics of piping layouts.

[0003] Currently, commonly used single-pipe fixtures can only secure a single pipe. When multiple pipes are running in parallel, a large number of pipe clamps are often required to effectively secure them. Existing double-row pipe fixtures often lack the ability to adjust the spacing between pipes, making them ineffective in scenarios with strict piping layout requirements. Utility Model Content

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In order to address the shortcomings of existing pipeline fixing devices in the case of complex pipeline layouts, this embodiment provides a double-row pipeline fixing device with variable spacing, which can achieve rapid fixing of double-row pipelines with different spacings.

[0035] like Figure 1As shown, the double-row pipe fixing device with variable spacing includes: two left and right clamping units and a sliding rod 2 that laterally connects the two clamping units; the left and right clamping units are used to clamp two pipes respectively; the two clamping units slide in cooperation with the sliding rod 2, and can move toward or away from each other relative to the sliding rod 2, thereby adjusting the spacing between the two clamping units to achieve double-row pipe fixing with different spacings.

[0036] Specifically, the two clamping units have the same structure, and both include: an upper clamping seat 1, a lower clamping seat 7 and a locking unit; the locking unit is used to fix the position of the pipeline after clamping.

[0037] like Figure 5 As shown, the lower end face of the upper clamping seat 1 has a semicircular groove, and the corresponding upper end face of the lower clamping seat 7 has a semicircular groove (the diameter of the processed semicircular groove directly matches the pipeline to be clamped); the upper clamping seat 1 and the lower clamping seat 7 are vertically opposite to each other, so that the two semicircular grooves are connected to form a circular through hole for the hoop pipeline, that is, the upper clamping seat 1 and the lower clamping seat 7 achieve the limitation of the pipeline through the mutual cooperation of the arc surface of the semicircular groove and the pipeline surface.

[0038] The outer sides of the two clamping units (i.e. the left side of the left angle unit and the right side of the right angle unit) are provided with locking units, which include: locking screw 8, rotating shaft 6 and butterfly nut 5. Figure 6 As shown, an upper lug 104 extends outward from the outer upper end of the upper clamping seat 1, and a lower lug 105 extends outward from the outer lower end of the lower clamping seat 7. Both the upper lug 104 and the lower lug 105 are machined with a U-shaped groove 103 for mounting the locking unit. Specifically, a locking screw 8 is vertically arranged, with a plain rod at the lower end and external threads at the upper end. The lower end of the locking screw 8 is mounted within the U-shaped groove 103 of the lower lug 105 via a rotating shaft 6 (the axial direction of the rotating shaft 6 is along the thickness direction of the clamping unit), allowing the locking screw 8 to rotate axially about the rotating shaft 6. When the locking screw 8 rotates axially about the rotating shaft 6, its upper end can either leave or enter the U-shaped groove 103 of the upper lug 104. A butterfly nut 5 engages with the upper end of the locking screw 8 threadedly, pressing the upper clamping seat 1 and the lower clamping seat 7 together. After the upper clamping seat 1 and the lower clamping seat 7 are docked and clamped to the pipeline, the upper end of the locking screw 8 is rotated into the U-shaped groove 103 of the upper support ear 104, and then the butterfly nut 5 is threadedly connected to the part of the screw extending out of the upper clamping seat 1, and the upper clamping seat 1 and the lower clamping seat 7 are fixed by the butterfly nut.

[0039] The two clamping units are connected by two slide bars 2, one of which connects the upper clamping bases 1 of the two clamping units, and the other connects the lower clamping bases 7 of the two clamping units. The two upper clamping bases 1 and the two lower clamping bases 7 slide on the corresponding slide bars 2 to adjust the spacing, thereby achieving the fixation of double-row pipes with different spacings.

[0040] like Figure 2 As shown, a long waist-shaped hole is processed on the slide bar 2 along its length direction as a slideway 201, and at the same time, limiting bosses B202 extend downward from both ends of the length direction of the slide bar 2.

[0041] like Figure 5 As shown, the upper end surface of the upper clamping seat 1 is provided with a sliding groove that slides with the slide rod 2. The sliding groove is open on the opposite sides of the two upper clamping seats 1, and a limiting boss A101 is provided at the open end (the limiting boss A101 is located on the bottom surface of the sliding groove, and the height is less than the height of the sliding groove); thus, the two ends of the slide rod 2 that cooperate with the two upper clamping seats 1 are respectively located in the sliding grooves of the two upper clamping seats 1, so that the two upper clamping seats 1 can slide along the slide rod 2, and then the spacing is adjusted.

[0042] The limiting boss A101 is provided with a screw hole 102, which is used to cooperate with the locking screw 3 to fix the relative position of the clamping unit and the slide bar 2 after the spacing is adjusted. That is, when the two upper clamping seats 1 slide along the slide bar 2 until the required spacing is met, the locking screw 3 passes through the guideway 201 on the slide bar 2 and is fixed in the screw hole 102 on the limiting boss A101 of the upper clamping seat 1, thus fixing the position.

[0043] The cooperation between the limiting boss A101 and the limiting boss B202 can realize the limiting function of adjusting the pipe spacing, such as Figure 3 and Figure 4 As shown, when the limiting bosses B202 at both ends of the slide rod 2 respectively conflict with the limiting bosses A101 at the open ends of the two upper clamping seats 1, the distance between the two clamping units is the largest; when the limiting bosses B202 at both ends of the slide rod 2 respectively conflict with the end faces of the other ends of the slide grooves of the two upper clamping seats 1 (the opposite ends of the open ends), the distance between the two clamping units is the smallest.

[0044] The structure of the lower clamping seat 7 and the way it cooperates with the slide bar 2 are the same as those of the upper clamping seat 1 described above. The only difference is that the lower end surface of the lower clamping seat 7 is provided with a sliding groove that slides with the slide bar 2 (it can also be understood that the upper clamping seat 1 can be directly turned upside down to be used as the lower clamping seat 7.)

[0045] Furthermore, to ensure that the two clamping units can only move laterally relative to each other, a pressure plate 106 is provided on the upper end surface of the slide groove of the upper clamping seat 1 (the lower end surface of the slide groove of the lower clamping seat 7). The slide rod 2 is located below the pressure plate 106 and slides with the lower end surface of the pressure plate 106. An open slot is provided on the pressure plate 106 at the position corresponding to the limiting boss A101 to prevent it from interfering with the installation of the locking screw 3.

[0046] The pipeline fixing device achieves pipeline clamping through the cooperation of the upper clamping seat 1 and the lower clamping seat 7. The locking screw 8 is installed on the lower clamping seat 7 via the rotating shaft 6, so that the locking screw 8 can rotate around the rotating shaft 6. When the pipeline needs to be fixed, the locking screw 8 is rotated into the U-shaped groove 103 of the upper clamping seat 1, and then the butterfly nut 5 is tightened to mate the upper clamping seat 1 with the lower clamping seat 7.

[0047] To adjust the pipe spacing, the upper clamping seat 1 and lower clamping seat 7 are moved relative to the slide bar 2. When the spacing is adjusted to the desired position, the locking screw 3 is inserted through the guideway 201 on the slide bar 2 and tightened into the screw hole 103 on the limiting boss A101 to fix the spacing. When the maximum spacing is reached, the limiting boss B202 on the slide bar 2 contacts the limiting boss A101 of the upper clamping seat 1 (and the lower clamping seat 7), achieving the position limit of the entire device.
