Utility Model Content

[0003] The technical problem solved by the utility model is to provide a lateral shockproof hanger which adopts a flexible connection to buffer the lateral swing caused by an earthquake.

[0004] The technical solution adopted by the utility model is: the lateral anti-vibration hanger includes a hanger rod with a cross-section of C-shaped channel steel, a hanger rod, a fixing device, a cross support rod and a positioning suspension device. The positioning suspension device includes a large nut and a fastener; the large nut is threadedly connected to the hanger rod. A positioning hole is processed on the side of the hanger rod (on both sides of the notch of the hanger rod); the fastener passes through the positioning hole and is fastened, and the fastener contacts the upper surface of the large nut and clamps the hanger rod, so that the weight of the hanger rod is applied to the large nut through the fastener.

[0005] Furthermore, the positioning suspension device further comprises a groove-shaped pad. The inner groove size of the groove-shaped pad corresponds to the width of the hanger rod, and a through hole is processed on the groove-shaped pad, and the through hole matches the positioning hole. The fastener passes through the through hole and the positioning hole on the groove-shaped pad and is fastened, so that the two sides of the hanger rod are evenly stressed.

[0024] The flexible connection described below refers to a non-fixed connection, or a non-rigid connection, which means that the two connected parts can move within a certain range. The flexible connection can achieve shock absorption, noise reduction, prevent displacement from damaging the pipeline, or facilitate adjustment of the installation position. The lateral direction refers to the side of the pipeline, which is consistent with the lateral direction described below. Example 1

[0025] The lateral anti-vibration hanger structure of this embodiment is shown in the attached figure. Figure 1-5 As shown, it includes a hanger rod 1, a hanger rod 9, a positioning suspension device 2, a fixing device, a horizontal support rod 6 and a vertical support rod 7. The cross section of the hanger rod 1 is a C-shaped channel steel, which is formed by cold bending of a steel strip, and a notch 13 is processed on the side of the notch. Figure 4 The other three sides are processed with positioning holes 11 and mounting holes 12. The mounting holes 12 are used for fasteners to connect cross bars or oblique support bars, such as cross support bar 6 and longitudinal support bar 7. Figure 1 and attached Figure 2 The positioning hole 11 cooperates with the positioning suspension device 2 to position the suspension rod 9 in two vertical directions. Figure 4 shown.

[0026] The fixing device is fixedly connected to the top surface of the building, and includes an expansion bolt 5 and a hanging block 4. The expansion bolt 5 fixes the hanging block 4 to the top surface of the building. The hanging block 4 is arc-shaped, and a long through hole 10 is processed in the middle along the arc direction. Figure 3 As shown, the length direction of the long through hole 10 is perpendicular to the pipeline axis direction, that is, the horizontal direction of the hanger. The top of the hanger rod 9 passes through the long through hole 10 and is suspended on the arc-shaped inner concave surface of the hanger block 4 by a nut. The arc-surface pad 8 is installed between the inner concave surface and the nut. The arc-surface pad 8 is consistent with the arc of the arc-shaped inner concave surface. In this way, the hanger rod 9 and the hanger rod 1 can be suspended on the inner concave surface of the hanger block 4 by gravity, or can be swung horizontally on the inner concave surface along the long through hole 10 (the horizontal direction is the cross-sectional direction of the pipeline, and the longitudinal direction is the conveying direction of the pipeline), or can be freely moved up and down within the distance between the top of the hanger rod and the top surface of the building, thereby forming a flexible connection with the building and the hanger block 4.

[0027] The suspension rod 9 is processed with external threads. In addition to being threadedly connected to the nut at the top, it is also matched with the positioning suspension device 2 at an appropriate position in the middle. The positioning suspension device 2 includes a large nut 3, a fastener 15, and a grooved pad 14. In this embodiment, the fastener 15 is a screw and a nut. The internal thread of the large nut 3 matches the suspension rod, increasing its external dimensions and being used to support the fastener 15. A nut is threadedly connected to the bottom of the large nut 3, as shown in the attached figure. Figure 3 As shown, the nut is a standard nut, which is only used to increase the number of load-bearing threads. When the load-bearing capacity of the hanger is low, the nut can be omitted and only the large nut 3 can be used. The inner groove size of the grooved pad 14 corresponds to the width size of the hanger rod 1. The grooved pad 14 is positioned by the corners of the hanger rod 1. The grooved pad 14 is processed with a through hole matching the positioning hole 11. The screw of the fastener 15 passes through the through hole and the positioning hole 11 and is fastened with a nut. Figure 4 As shown. The fastener 15 is installed on both sides of the notch 13, and the two screws are in contact with the upper surface of the large nut 3, transferring the weight of the hanger rod 1 to the large nut. At the same time, the hanger rod is clamped to limit the position of the hanger rod in this direction. The fastener 15 and the grooved pad 14 are also installed on the notch 13 and the opposite side of the hanger rod. Since the notch cannot support the fastener 15, the grooved pad 14 must be used. The two screws in the fastener 15 do not bear weight, but only clamp the hanger rod to limit the position of the hanger rod in another direction. In this way, through the positioning suspension device, the hanger rod 1 is suspended on the large nut 3 by gravity, and the fasteners 15 that clamp the hanger rod perpendicularly to each other define the horizontal position size between the hanger rod and the hanger rod. Even if the hanger rod rotates, the fastener 15 that suspends the hanger rod will not separate from the large nut. But it can move up and down between the two sets of positioning fasteners 15, thereby forming a flexible connection.

[0028] Since the installation position of the positioning suspension device is not at the notch, the grooved pad can be omitted. However, this embodiment uses the non-concentricity between the through hole on the grooved pad and the positioning hole 11 to limit the fastener 15, thereby preventing the fastener 15 from moving due to the gap in the positioning hole and preventing the suspension rod from being unable to be clamped.

[0029] The structure of the horizontal support rod 6 is as shown in the attached Figure 5 As shown, it is obliquely installed on the lateral side of the hanger rod. The horizontal support rod is a slowly breathable cylinder structure, including a blind plate 61, a cylinder sleeve 62, a piston 63, a flange 64, a connecting rod 65, etc. The blind plate 61 blocks one end of the cylinder sleeve 62, and the piston 63 is located in the cylinder sleeve 62. One end of the piston 63 is connected to the connecting rod 65, which is inserted into the cylinder sleeve end of the connecting rod 65, and the flange 64 is installed to prevent the piston 63 from slipping off. There is a gap 66 between the piston 63 and the inner surface of the cylinder sleeve 62. When the piston 63 is pressed into the cylinder sleeve, the gas pressure in the cylinder sleeve increases and overflows from the gap 66. When the piston is pulled out of the cylinder sleeve, the gas pressure in the cylinder sleeve decreases, and the outside air can enter the cylinder sleeve through the gap to maintain the air pressure balance. The cylinder sleeve 62 and the connecting rod 65 are hinged to the top surface of the building and the hanger rod respectively. When the hanger rod swings horizontally, the cylinder sleeve 62 and the connecting rod 65 can be adjusted to be in a straight line by hinged connection to ensure the cooperation and sliding of the piston 63 and the cylinder sleeve 62. The horizontal support rod of the cylinder structure is beneficial to buffer the lateral swing of the hanger rod through the air pressure balance process between the cylinder sleeve 62 and the outside world, thereby playing a role in shock absorption and shock prevention. This connection method is also a flexible connection.

[0030] The longitudinal support rod connects the hanger rod and the top surface of the building in the longitudinal direction of the pipeline. It is a rigid fixed connection to prevent the longitudinal swing of the pipeline during installation.

[0031] This embodiment uses flexible connections such as arc swing, suspension, and air pressure balance buffer to avoid the impact of lateral vibration on the pipeline, play a role in lateral shock prevention, and effectively protect the pipeline.

[0032] It should be noted that 1) even if there is no fastener 15 at the notch to clamp the suspension rod, the above-mentioned anti-vibration purpose can be achieved. Figure 4 As shown, assuming that Figure 4 The left and right directions are horizontal. If the hanger swings horizontally, the hanger rod drives the large nut to move in the space defined by the fastener 15 and will not be separated from the fastener 15. Figure 4 The up and down direction is horizontal. When the hanger swings horizontally, it will drive the hanger rod to swing horizontally together, and it will not be separated from the fastener 15. Therefore, the fastener 15 installed at the notch plays a role of safety and limit. 2) The grooved pads 14 can be omitted on both sides of the notch. The screw rod can be fastened with nuts after passing through the positioning holes 11. The hanger rod can also be limited. However, after using the grooved pads 14, the pre-tightening force of the fastener is evenly applied on the side plates of the C-shaped channel steel. Example 2

[0033] To simplify installation, the screw rod in Example 1 can be replaced with a long bolt, so that the operation of screwing four nuts on one hanger rod can be reduced. Figure 6 Similarly, the top of the suspension rod can also be directly made into a bolt head to replace the nut. After all, it is difficult to screw the nut in a narrow space. First, pass the suspension rod 9 through the long through hole, and then fix the suspension block 4, as shown in the attached figure. Figure 7 If the pipeline is close to the wall of the building, the cross bar can be directly installed horizontally on the wall, which not only requires less material, but also is easy to install and is also conducive to the sliding fit between the piston 63 and the cylinder sleeve 62. Example 3

[0034] In order to simplify and reduce the number of installed parts and facilitate engineering construction and installation, this embodiment improves the structure of some parts. Figure 8 and attached Fig. 9 In this embodiment, the suspension rod 9 and the arc pad 8 are integrated into an integrated suspension rod 16, that is, an arc-shaped head integrated with the suspension rod is processed at the top of the integrated suspension rod 16, and the arc matches the inner concave surface of the suspension block. When installing, the integrated suspension rod 16 can be passed through the long through hole 10, and the head of the integrated suspension rod 16 is suspended and load-bearing.

[0035] The structural changes of the positioning suspension device are as follows: Fig.10 As shown, the original large nut 3 is changed into a special nut 17, and the special nut 17 is as shown in the attached Fig.10 As shown, two symmetrical support plates 18 are processed on both sides of the nut body 20 and are integrated with the nut. A through hole 19 is processed on each support plate 18, and the through hole 19 matches the positioning hole 11. The positioning suspension device of this embodiment omits the installation at the notch position, so the grooved pad installed at the notch is omitted. At the same time, the through hole 19 can replace the role of the through hole on the grooved pad 14, and the grooved pad installed at the non-notch position is also omitted. During installation, the bolt of the fastener 15 passes through the positioning hole 11 and the through hole 19 on the special nut 17, and is tightened. The hanger rod 1 applies gravity to the special nut 17 through the fastener 15, and the special nut 17 applies force to the integrated hanger rod 16 through a threaded connection. The fastener 15 cooperates with the through hole 19, and the special nut and the hanger rod are threadedly connected, which limits the plane movement, rotation and up and down movement of the hanger rod.

[0036] Compared with Example 2, this embodiment has fewer parts and is more convenient to install. The integrated suspension rod 16 passes through the long through hole 10, is threadedly connected with the special nut 17, and the suspension block 4 is fixed with the expansion bolt 5. The integrated suspension rod 16 is inserted into the notch 13 of the hanger rod, and the fastener 15 passes through the positioning hole 11 and the through hole 19 in sequence, and the nut is tightened to complete the installation of the hanger rod. Then the horizontal support rod and the vertical support rod are installed.

[0037] The utility model utilizes the suspension flexible connection and the air pressure balance of the air-permeable cylinder cross-bracing rod to buffer the vibration displacement, so that the shockproof hanger has a strong lateral shockproof ability. During an earthquake, only lateral shaking occurs without causing structural damage, which can effectively protect the pipeline on the hanger and prevent the pipeline from being bent or leaking due to lateral force.
