Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brackets, in particular to a sliding bracket for a thermal pipe. Background Art
[0002] Thermal pipes are pipes that transport thermal energy media such as steam or superheated water. Thermal pipes are usually supported by sliding brackets. The sliding brackets have slide supports and slide grooves. By sliding the pipes, they can move on the slide grooves along the pipe axis to adapt to the expansion and contraction of the pipes. The sliding brackets allow the pipes to move in the horizontal plane and only provide support in the vertical plane.
[0003] In the prior art, the sliding bracket wraps around the thermal pipe through a clamp, fixes the position of the thermal pipe through the clamp and supports the thermal pipe. When the thermal pipe is axially displaced, the clamp and the slide bracket move on the slide groove to prevent friction when the thermal pipe is displaced.
[0004] However, when the thermal pipe is transporting steam or superheated water, it will expand due to the high temperature. The sliding bracket is rigidly connected to the thermal pipe through a clamp. The expansion deformation of the thermal pipe and the mutual compression of the sliding bracket may cause the thermal pipe to break due to excessive pressure. Utility Model Content

[0007] A mounting plate, a sliding assembly is disposed on the top of the mounting plate, and a fixing bracket is disposed on the top of the sliding assembly;
[0008] The yielding assembly comprises a yielding arc plate, a butt plate and a yielding groove, wherein the end of the yielding arc plate is fixedly mounted with an inclined butt plate, the inner arc surface of the fixed bracket is provided with a yielding groove, the butt plate is located at the yielding groove of the inner arc surface of the fixed bracket, and the butt plate contacts the yielding groove;

[0010] Optionally, the abutment plate and the yielding arc plate form a lever, and the larger the opening between the two yielding arc plates, the larger the opening of the two abutment plates, and the larger the vertical distance between the abutment plate and the mounting plate.
[0011] Optionally, the give-way component also includes a sliding sleeve, and the two sides of the sliding sleeve are rotatably connected to two give-way arc plates through a rotating shaft, and the give-way arc plate and the sliding sleeve are elastically connected through a torque spring. An insertion groove is opened at the center of the sliding sleeve, and a guide square rod is fixedly installed at the give-way groove on the inner arc surface of the fixed bracket. The guide square rod is inserted into the insertion groove, and the sliding sleeve slides on the guide square rod.
[0012] Optionally, the end of the abutment plate is rotatably connected to a roller, and the roller rolls in a clearance groove on the inner arc surface of the fixed bracket.
[0013] Optionally, the sliding assembly includes a mounting seat, an axial slider and a radial slider, the bottom of the axial slider is slidably connected to the axial slide groove, the bottom of the radial slider is slidably connected to the axial slider, the bottom of the mounting seat is fixedly connected to the mounting plate, and the top of the radial slider is fixedly connected to the fixed bracket.

[0016] Compared with the prior art, the utility model has the following beneficial technical effects:
[0017] When the thermal tube expands, the two yielding arc plates in one group are stretched open to adapt to the size of the thermal tube, and then the abutment plate at the end of the yielding arc plate rotates, a gap is generated between the abutment plate and the mounting plate, the thermal tube expands and squeezes the yielding arc plate to move it upward, and the distance between the two groups of yielding arc plates is increased, so that the thermal tube is prevented from being damaged by mutual squeezing between the yielding arc plates after expansion, thereby solving the problem of damage caused by mutual squeezing between the thermal tube expansion and the sliding bracket.
[0018] Furthermore, after the yielding arc plate is pushed toward the mounting plate by the expansion of the thermal tube, the resisting plate resists the mounting plate again. At this time, the resisting plate and the yielding arc plate will not be able to move, and their positions are fixed, that is, the thermal tube is fixed. After the yielding arc plate rotates, the yielding arc plate and the resisting plate cooperate to have a positioning effect on the thermal tube.

The thermal tube allows the radial slider to slide in the radial groove through the yielding assembly and the fixed bracket, thereby avoiding radial displacement of the other side caused by the axial expansion of the thermal tube, and causing the thermal tube and the sliding bracket to squeeze and deform each other.

[0030] Example 1
[0031] This embodiment provides a sliding bracket for a thermal pipe, such as Figure 1 As shown, it includes a mounting plate 1, a sliding assembly 2 is arranged on the top of the mounting plate 1, and a fixing bracket 3 is arranged on the top of the sliding assembly 2; the mounting plate 1 is fixed to the ground by screws, and the position of the fixing bracket 3 is fixed by the mounting plate 1 and the sliding assembly 2, and two fixing brackets 3 are provided, and the two fixing brackets 3 are symmetrically arranged, and the two fixing brackets 3 are fixed together by bolts to form a ring, and the thermal pipe is installed in the fixing bracket 3. The thermal pipe is sheathed by the two fixing brackets 3 to fix the position of the thermal pipe.
[0032] like Figure 2 and 3 As shown, the yielding assembly 4 includes a yielding arc plate 41, a stop plate 42, and a yielding groove 43. The yielding arc plates 41 are provided in two groups, two yielding arc plates 41 form a group, and the two yielding arc plates 41 in one group are in a scissor-shaped structure. The two groups of yielding arc plates 41 form a ring structure, and the inner arc surface of the yielding arc plate 41 contacts the thermal pipe. The two groups of yielding arc plates 41 clamp the thermal pipe together to fix the position of the thermal pipe.
[0033] An inclined abutment plate 42 is fixedly installed at the end of the yield arc plate 41. The abutment plate 42 and the yield arc plate 41 form a lever. The larger the opening between the two yield arc plates 41, the larger the opening of the two abutment plates 42, and the larger the vertical distance between the abutment plate 42 and the mounting plate 1.
[0034] like Figure 3As shown, the inner arc surface of the fixed bracket 3 is provided with a clearance groove 43, and the abutment plate 42 is located at the clearance groove 43 of the inner arc surface of the fixed bracket 3, and the abutment plate 42 contacts the clearance groove 43; the clearance groove 43 is used for the abutment plate 42 to rotate and move up and down. The end of the abutment plate 42 is rotatably connected with a roller, and the roller rolls in the clearance groove 43 on the inner arc surface of the fixed bracket 3. The friction between the clearance groove 43 and the mounting plate 1 is reduced when the rotation occurs.
[0035] When the heat pipe expands due to heat, the two yielding arc plates 41 in one group are stretched open, so that the opening of the abutment plate 42 at the end of the yielding arc plates 41 in the group increases. As the opening of the abutment plate 42 increases, the vertical distance from the abutment plate 42 to the mounting plate 1 increases, and the expansion of the heat pipe can push the yielding arc plates 41 and the abutment plate 42 upward, and the positions of the yielding arc plates 41 and the abutment plate 42 are fixed again. When the heat pipe expands, the distance between the two groups of yielding arc plates 41 increases, and the opening of the two yielding arc plates 41 in one group increases, so as to avoid the yielding arc plates 41 being squeezed against each other and causing damage after the heat pipe expands.
[0036] like Figure 2 As shown, the yielding assembly 4 also includes a sliding sleeve 45, and the two sides of the sliding sleeve 45 are respectively rotatably connected to the two yielding arc plates 41 through a rotating shaft, and the yielding arc plates 41 and the sliding sleeve 45 are elastically connected through a torque spring. An insertion groove 46 is provided at the center of the sliding sleeve 45, and a guide square rod 44 is fixedly installed at the yielding groove 43 of the inner arc surface of the fixed bracket 3. The guide square rod 44 is inserted into the insertion groove 46, and the sliding sleeve 45 slides on the guide square rod 44. The guide square rod 44 guides the sliding sleeve 45 and prevents the sliding sleeve 45 from rotating.
[0037] The push plate 42 serves as a lever arm, and its length is short. The force required to squeeze the push plate 42 to open it so as to open the yield arc plate 41 is large, and the elastic force of the torque spring needs to be overcome.
[0038] In this embodiment, when the thermal tube expands, two yielding arc plates 41 in one group are stretched open to adapt to the size of the thermal tube, and then the abutment plate 42 at the end of the yielding arc plate 41 rotates, and a gap is generated between the abutment plate 42 and the mounting plate 1. The thermal tube expands and squeezes the yielding arc plate 41 to move it upward, and the distance between the two groups of yielding arc plates 41 increases, thereby preventing the thermal tube from being squeezed against the yielding arc plates 41 after expansion and causing damage. At the same time, since the abutment plate 42 abuts against the mounting plate 1, the positions of the abutment plate 42 and the yielding arc plate 41 are stable, thereby solving the problem of damage caused by the thermal tube expansion and the sliding bracket squeezing each other.
[0039] Example 2
[0040] Based on Example 1, this embodiment proposes a sliding bracket for a thermal pipe, such as Figure 1 and 4As shown, the sliding assembly 2 includes a mounting seat 21, an axial slider 23 and a radial slider 25. The top of the mounting seat 21 is provided with an axial slide groove 22 for the axial slider 23 to slide. The bottom of the axial slider 23 is slidably connected to the axial slide groove 22. The top of the axial slider 23 is provided with a radial slide groove 24 for the radial slider 25 to slide. The bottom of the radial slider 25 is slidably connected to the axial slider 23. The directions of the axial slide groove 22 and the radial slide groove 24 are perpendicular to each other. The axial slider 23 slides in the axial slide groove 22 to cooperate with the axial expansion and contraction of the thermal pipe. The radial slider 25 slides in the radial slide groove 24 to cooperate with the radial expansion and contraction of the thermal pipe.
[0041] like Figure 3 and 4 As shown, the bottom of the mounting seat 21 is fixedly connected to the mounting plate 1, and the top of the radial slider 25 is fixedly connected to the fixing bracket 3. The thermal pipe is bent at a right angle, and when the thermal pipe on one of the right-angle sides is axially deformed, the thermal pipe on the other side will be driven to radially displace, and the thermal pipe makes the radial slider 25 slide in the radial groove 24 through the giving way component 4 and the fixing bracket 3.
[0042] In this embodiment, when the thermal tube is bent at a right angle, when the thermal tube on one of the right-angle sides undergoes axial deformation, the thermal tube on the other side will be driven to undergo radial displacement. The thermal tube allows the radial slider 25 to slide in the radial slide groove 24 through the yielding component 4 and the fixed bracket 3, thereby avoiding radial displacement of the other side caused by the axial expansion of the thermal tube, and causing the thermal tube and the sliding bracket to squeeze and deform each other.
[0043] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
