Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a quick-install adjustable pipeline bracket. Background Art

[0002] Aerated sewage treatment pipelines are equipped with a large number of pipe supports. Every time the equipment is inspected and adjusted, it takes a lot of time to disassemble and clamp the pipes. The current pipe support mainly clamps the pipe in the following ways: ① Clamp base + bolt fixing; ② Saddle seat + glue fixing. The clamp base fixing and disassembly are more troublesome because four screws need to be installed, and the screws are easy to rust or get entangled in mud and fabric, etc., and cannot be disassembled; and the saddle seat is easy to be misplaced and fall off due to glue. Therefore, it is now necessary to design a quick-install adjustable pipe support with a long service life and simple disassembly and assembly to meet the requirements of quick replacement of aerators. Utility Model Content

[0003] The utility model aims at the deficiencies in the prior art and provides a quick-install adjustable pipe bracket with a simple structure and reasonable design. No matter how tight the thread is during operation, it can be easily disassembled by simply turning the eccentric cam wrench in the opposite direction, thereby providing great convenience for maintaining aeration tank equipment.

[0004] In order to achieve the above-mentioned object, the utility model provides a quick-install adjustable pipe support, comprising a first clamping member and a second clamping member, wherein the first clamping member and the second clamping member are both semicircular tile-shaped, and together form a hug for the gas transmission pipe;

[0005] The first clamping member and the second clamping member are hinged on one side, and are commonly connected to a pull rod on the other side;

[0006] A first folded edge is provided at the connection between the first clamping member and the pull rod, and the first folded edge extends away from the first clamping member;

[0007] A second folded edge is provided at the connection between the second clamping member and the pull rod, and the second folded edge extends away from the second clamping member;

[0008] An eccentric cam spanner is hinged at one end of the pull rod, and a thread is provided at the other end and is threadedly connected to a butterfly nut;

[0009] The back side of the middle part of the first clamping member is connected with an upper support column, and the upper support column is threadedly connected with a lower support column.

[0010] A bottom fixing plate is connected to the bottom of the lower support column. The bottom fixing plate is provided with through holes and is fixedly connected to the bottom of the aeration tank via the through holes.

[0011] Furthermore, the lower support column is cylindrical, and the outer wall is provided with external threads throughout;

[0012] The upper support column is cylindrical, and the inner wall is provided with an internal thread that matches the so-called external thread.

[0013] Furthermore, the first folded edge is provided with a first reinforcement block, and the second folded edge is provided with a second reinforcement block, and the first reinforcement block and the second reinforcement block are symmetrical along the connecting surface of the first folded edge and the second folded edge.

[0014] Furthermore, the first reinforcement block and the second reinforcement block are provided with through holes, and the pull rod passes through the through holes.

[0015] Furthermore, a stepped hole is provided in the middle of a surface of the first reinforcement block facing away from the second reinforcement block, and the bottom of the butterfly nut is located in the stepped hole.

[0016] Furthermore, an arc groove is provided in the middle of a surface of the second reinforcement block facing away from the first reinforcement block, and the cam of the eccentric cam wrench is located in the arc groove.

[0017] During installation, first fix the bottom fixing plate to the aeration tank, and then rotate the upper support column to adjust the height of the first clamp. At the appropriate height, rotate the first clamp in the correct direction. The actual height deviation from the required height will not be greater than one pitch, which is harmless.

[0018] After the gas pipeline is arranged, close the second clamping piece on the first clamping piece from the hinge. At this time, the first reinforcement block and the second reinforcement block are overlapped, the through holes of the two are aligned, and the pull rod thread is passed downward through the through hole, and the butterfly nut is installed and tightened appropriately.

[0019] Turn the eccentric cam wrench to tighten the tie rod.

[0020] The bolts that are screwed in seem to be very tight, but they are actually very easy to loosen in vibration. This is because during the tightening process, the bolts have not yet reached the shortest position, but the bolts and surrounding parts have formed a self-locking force with sufficient friction. To tighten the bolts is equivalent to pulling the bolts with the nut. In the case of self-locking, the pressure of pulling the bolts cannot overcome the friction. However, during vibration, it can cause the jump between the internal and external threads, and between the bolts and parts. The friction will fail temporarily, and the axial tension of the bolts will adjust the bolts to the shortest position, causing the bolts to loosen. Therefore, when the butterfly nut feels that it has been screwed to the bottom, pulling the eccentric cam wrench to tighten the tie rod will cause the tie rod to have more elastic deformation. In this way, even if the tie rod is vibrated during vibration, the extra elastic deformation can still tighten the butterfly nut. Bolt connections that can still be locked after a round of vibration are reliable.

[0021] Moreover, when tightening the bolts, you don't need to use a lot of force, just enough. Moreover, turning the eccentric cam wrench is quick and easy to operate.

[0022] The second reinforcing block is provided with an arc groove, so as to force the cam of the eccentric cam wrench to move toward the through hole, thereby contributing to the reliability of locking the eccentric cam wrench at the maximum distance.

[0023] The beneficial effects of this solution can be known from the description of the above solution. It has a simple structure and a reasonable design. No matter how tight the thread is during operation, it can be easily disassembled by simply turning the eccentric cam wrench in the opposite direction, thereby providing great convenience for maintaining the aeration tank equipment.

DETAILED DESCRIPTION

[0029] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0030] like Figure 1-4 As shown, this embodiment is a quick-install adjustable pipe support, comprising a first clamping member 1 and a second clamping member 2, the first clamping member 1 and the second clamping member 2 are both semicircular tile-shaped, together forming a hug for the gas transmission pipe;

[0031] The first clamping member 1 and the second clamping member 2 are hinged on one side, and are connected to a pull rod 3 on the other side;

[0032] A first folded edge 4 is provided at the connection between the first clamping member 1 and the pull rod 3, and the first folded edge 4 extends away from the first clamping member 1;

[0033] A second folded edge 5 is provided at the connection between the second clamping member 2 and the pull rod 3, and the second folded edge 5 extends away from the second clamping member 2;

[0034] An eccentric cam spanner 6 is hinged at one end of the pull rod 3, and a thread is provided at the other end and a butterfly nut 7 is threadedly connected thereto;

[0035] The back side of the middle part of the first clamping member 1 is connected with an upper support column 8 , and the upper support column 8 is threadedly connected with a lower support column 9 .

[0036] A bottom fixing plate 10 is connected to the bottom of the lower support column 9. The bottom fixing plate 10 is provided with through holes and is fixedly connected to the bottom of the aeration tank through the through holes.

[0037] Furthermore, the lower support column 9 is cylindrical, and the outer wall is provided with external threads throughout;

[0038] The upper support column 8 is cylindrical, and the inner wall is provided with an internal thread that matches the so-called external thread.

[0039] Furthermore, the first folded edge 4 is provided with a first reinforcement block 11 , and the second folded edge 5 is provided with a second reinforcement block 12 . The first reinforcement block 11 and the second reinforcement block 12 are symmetrical along the connecting surface of the first folded edge 4 and the second folded edge 5 .

[0040] Furthermore, the first reinforcement block 11 and the second reinforcement block 12 are provided with through holes, and the pull rod 3 passes through the through holes.

[0041] Furthermore, a stepped hole 13 is provided in the middle of a surface of the first reinforcement block 11 facing away from the second reinforcement block 12 , and the bottom of the butterfly nut 7 is located in the stepped hole 13 .

[0042] Furthermore, an arc groove 14 is provided in the middle of a surface of the second reinforcement block 12 facing away from the first reinforcement block 11 , and the cam of the eccentric cam wrench 6 is located in the arc groove 14 .

[0043] During installation, first fix the bottom fixing plate 10 to the aeration tank, and then rotate the upper support column 8 to adjust the height of the first clamping member 1. At the appropriate height, rotate the first clamping member 1 in the correct direction, and the actual height deviation from the required height will not be greater than one pitch, which is harmless.

[0044] After the gas pipeline is arranged, the second clamping member 2 is closed on the first clamping member 1 at the hinge. At this time, the first reinforcement block 11 and the second reinforcement block 12 are overlapped, the through holes of the two are aligned, and the pull rod 3 is threaded downward through the through hole, and the butterfly nut 7 is installed and tightened appropriately.

[0045] Turn the eccentric cam wrench 6 to tighten the pull rod 3.

[0046] The bolts that are screwed in seem to be very tight, but they are actually very easy to loosen in vibration. This is because during the tightening process, the bolts have not yet reached the shortest position, but the bolts and surrounding parts have formed a self-locking with sufficient friction. To tighten the bolts is equivalent to pulling the bolts with the nut. In the case of self-locking, the pressure of pulling the bolts cannot overcome the friction. However, during vibration, it can cause the jump between the internal and external threads, and between the bolts and parts. The friction will fail temporarily, and the axial tension of the bolts will adjust the bolts to the shortest position, causing the bolts to loosen. Therefore, when the butterfly nut 7 feels that it has been screwed to the bottom, pulling the eccentric cam wrench 6 to tighten the tie rod 3 will cause the tie rod 3 to have more elastic deformation. In this way, even if the tie rod 3 is vibrated during vibration, the extra elastic deformation can still tighten the butterfly nut 7. Bolt connections that can still be locked after a round of vibration are reliable.

[0047] And, when tightening the bolt, it is not necessary to spend much effort, just about the same. And, pulling the eccentric cam spanner 6 is quick and easy to operate.

[0048] The second reinforcing block 12 is provided with an arc groove 14 in order to force the cam of the eccentric cam wrench 6 to move toward the through hole, thereby facilitating the reliability of locking the eccentric cam wrench 6 at the maximum distance.
