Description

Technical Field

[0001] This utility model relates to the field of support and hanger technology, and in particular to a constant force spring support and hanger. Background Technology

[0002] Hangers are designed based on the principle of torque balance. Within a specified load displacement range, the load torque and spring torque remain balanced. Therefore, when pipes and equipment supported by constant hangers experience displacement, a constant supporting force is obtained, preventing additional stress on the pipes and equipment. Constant hangers are generally used in places where displacement stress needs to be reduced, such as the main body of power plant boilers, the suspended parts of steam, water, and flue gas ducts and burners in power plants, as well as petrochemical equipment and other places where displacement stress needs to be reduced.

[0003] A search revealed in Publication No. CN215488064 U disclosed a constant force spring support bracket, comprising a fixed frame with windows at the front and rear, and legs fixedly connected to the lower end face of the fixed frame; a main spring device is installed longitudinally within the fixed frame; auxiliary spring devices acting on the main spring device are also installed in the fixed frames on the left and right sides of the main spring device; an auxiliary adjustment device acting longitudinally on the main spring device is also included; the auxiliary adjustment device is installed on the front and rear sides of the main spring device; and fine-tuning devices are added above and below the auxiliary spring device. The purpose of this utility model is to overcome the defects of the prior art and provide a constant force spring support bracket that is easy to adjust and has high adjustment accuracy.

[0004] While the above solution enables quick assembly and disassembly of the locking bolts, and allows for longitudinal adjustment with the locking nut, offering a simple and highly accurate adjustment method, it is inconvenient to adjust the height of the load-bearing support device to support horizontal pipes at different heights during use. Therefore, we propose a constant force spring support bracket. Utility Model Content

[0005] The main purpose of this utility model is to provide a constant force spring support bracket, which solves the problem of inconvenient height adjustment of the load support device in order to support horizontal pipes of different heights during use, through the setting of support unit and side support unit.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A constant force spring support includes a main unit, a support unit and a side support unit disposed inside the main unit, and a fixing unit disposed on the surface of the main unit;

[0008] The support unit includes a support base installed below the main body unit, a main spring component installed above the support base, a main spring sleeve wheel installed on top of the main spring component, a main spring pressure plate installed on top of the main spring sleeve wheel, and a load-bearing component installed above the main spring pressure plate.

[0009] The side support unit includes a cam cutter movably installed inside the main body unit and in contact with the main spring sleeve wheel, and a side spring component disposed inside the main body unit.

[0010] Preferably, the main body unit includes a fixed frame and a support leg installed at the bottom of the fixed frame.

[0011] Preferably, the main spring includes a main spring cylinder mounted on the top of the support base, and a first spring mounted on the bottom wall of the main spring cylinder.

[0012] Preferably, the load-bearing component includes a load cylinder mounted on the top of the main spring pressure plate and movably passing through the fixed frame, and a load column mounted on the top of the load cylinder.

[0013] Preferably, the side spring includes a connecting plate installed on the inner side wall of the fixed frame, a second spring installed on the side wall of the connecting plate, a side spring pressure plate installed on the end of the second spring, and a transmission plate installed on the side wall of the side spring pressure plate and movably connected to the cam cutter.

[0014] Preferably, the fixing unit includes a fixing groove formed on the side wall of the fixing frame, a reinforcing plate installed on the side wall of the fixing frame, a plurality of engaging grooves formed on the inner side wall of the reinforcing plate, a movable frame installed on the side wall of the main spring sleeve wheel, two engaging members movably disposed in the movable frame, and a third spring disposed between the two engaging members.

[0015] Preferably, the engaging component includes a movable through hole formed in the side wall of the movable frame, an engaging post that is movably inserted through and disposed in the movable through hole, and an engaging pressure plate that is movably inserted through the movable frame and fixedly connected to the engaging post.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, by using the support unit and side support unit, when the height of the horizontal tube support needs to be adjusted according to the actual height, the two clamping plates are pressed towards each other, causing the third spring to be compressed until the locking column disengages from the locking groove on the inner wall of the reinforcing plate. At this time, the load-bearing component can be moved up and down by the moving frame until the load-bearing column can support the horizontal tube to be supported. At this time, the force applied to the clamping plate is removed, and under the elastic force of the third spring, the locking column can automatically engage with the locking groove on the inner wall of the reinforcing plate. When the horizontal tube deforms due to thermal expansion and contraction, due to the setting of the main spring and side spring, under the elastic force of the first spring, the load-bearing component can always be in contact with the bottom of the horizontal tube, thereby achieving stable support for the horizontal tube and avoiding support separation caused by the deformation of the horizontal tube due to thermal expansion and contraction.

[0032] like Figure 4 As shown, the side support unit 3 includes a cam blade 301 that is movably installed inside the main body unit 1 and fits against the main spring sleeve wheel 203, and a side spring member 302 that is disposed inside the main body unit 1. The side spring member 302 is disposed so that the cam blade 301 always acts on the main spring sleeve wheel 203.

[0033] like Figure 1 As shown, the main unit 1 includes a fixed frame 101 and a support leg 102 installed at the bottom of the fixed frame 101. The support leg 102 provides support for the stable operation of the entire support frame.

[0034] like Figure 4 As shown, the main spring 202 includes a main spring cylinder 2021 installed on the top of the support base 201, and a first spring 2022 installed on the inner bottom wall of the main spring cylinder 2021.
