Abstract
Description
Technical Field
[0001] The present application relates to the technical field of equipment maintenance brackets, and in particular to a TEP muffler support and fixing device. Background Art
[0002] TEP silencers are used at the outlet of TEP compressors in nuclear power plants to reduce the noise generated during the operation of the compressor. TEP silencers generally include a first section and a second section. The two sections are fixedly connected coaxially through a flange set and fasteners, and a sealing gasket is clamped and fixed between the flange sets. When the sealing gasket is damaged or aged during use, it will cause leakage at the flange set in the middle section of the TEP silencer. At this time, the faulty TEP silencer needs to be maintained and disposed of. The disposal process includes: removing the TEP silencer and disassembling the fasteners, separating the first section and the second section of the TEP silencer, replacing a new sealing gasket and re-docking the first section and the second section, and then locking and fixing the first section and the second section with fasteners.
[0003] During the disposal process, in order to ensure that the sealing gasket is installed horizontally on the flange of the corresponding section, the TEP silencer needs to be placed vertically in a posture perpendicular to the ground. However, the two ends of the TEP silencer are generally designed to be round-headed or irregularly shaped, and it is difficult to keep it in a vertical posture without the help of specific supporting and fixing devices. The existing disposal method is to use a fixed iron fence to tie it up while the vehicle is not unhooked to ensure the stability of the TEP silencer, but this disposal method still has the risk of the TEP silencer tilting and tipping over. Therefore, it is necessary to provide a TEP silencer support and fixing device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0024] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. According to the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0025] See also Figure 1 to Figure 2 The present application provides a TEP muffler support and fixing device, which is used to support and fix the TEP muffler 100 so that the TEP muffler 100 is kept fixed in a vertical posture. The device of the present application includes a base 1, a limit bracket 2 and a caster assembly 5. A support structure 3 is provided on the base 1. The limit bracket 2 is fixedly connected to the base 1 and extends vertically along the length direction of the TEP muffler 100, and a limit structure 4 is provided on the upper part of the limit bracket 2. In actual use, at least part of the section of the TEP muffler 100 (the lower section is used as an example in this embodiment) is limited by the limit bracket 2, and the bottom of the TEP muffler 100 is pressed against the support structure 3, and the middle side wall of the TEP muffler 100 is pressed against the corresponding limit structure 4, so that the TEP muffler 100 maintains a vertical posture. The caster assembly 5 is provided at the bottom of the base 1, and is used to drive the base 1, the limit bracket 2 and the TEP muffler 100 to move.
[0026] The TEP silencer support and fixing device provided in the present application supports and limits the bottom of the TEP silencer 100 through the support structure 3 on the base 1, and supports and limits the middle side wall of the TEP silencer 100 through the limiting structure 4 on the limiting bracket 2, so that the lower section of the TEP silencer 100 is vertically supported and limited in the limiting bracket 2, so that the TEP silencer 100 can be firmly supported and fixed on the device of the present application in a vertical posture perpendicular to the ground. The structure of the device of the present application is simple, and the supporting and limiting effect on the TEP silencer 100 is good, which effectively avoids the problem of the TEP silencer 100 being prone to tilting or tipping during maintenance. In addition, the TEP silencer support and fixing device provided in the present application can drive the base 1, the limiting bracket 2 and the TEP silencer 100 to move through the caster assembly 5, which is convenient for the transfer and position adjustment of the TEP silencer 100, and improves the maintenance and disposal efficiency of the TEP silencer 100.
[0027] See also Figure 1 and Figure 2 The upper and lower ends of the TEP silencer 100 are both round-head structures, and are mainly composed of a first section 101 and a second section 102. The main parts of the first section 101 and the second section 102 are both long cylindrical structures, which are fixed together by a flange set 103 and a fastener 104, and the first section 101 and the second section 102 are on the same axis. After the fixed connection, the flange set 103 is roughly located in the middle position of the TEP silencer 100, and a sealing gasket (not shown) is clamped and fixed between the flange set 103 for sealing. When the TEP silencer 100 is vertically supported and fixed on the device of the present application, the first section 101 can be located at the bottom, or the second section 102 can be located at the bottom, and the present application does not limit this. In this embodiment, the second section 102 is located at the bottom as an example for explanation.
[0028] See also Figure 1 and Figure 2 Preferably, the TEP silencer supporting and fixing device provided by the present application has a top of a limiting bracket 2 extending to below the flange set 103 of the TEP silencer 100. This structural design enables the present application device to directly limit and fix the second section 102 of the TEP silencer 100 located at the bottom, while the first section 101 of the TEP silencer 100 located at the top is not directly constrained by the present application device. During the actual maintenance and treatment process, the first section 101 can be lifted and separated by a lifting device after the fastener 104 is removed, thereby facilitating the operator to replace the damaged gasket. Moreover, under the supporting and fixing action of the present application device, the gasket can be horizontally installed on the flange of the second section 102, which facilitates the maintenance and treatment of the TEP silencer 100.
[0029] See also Figure 3 and Figure 4 As a preferred embodiment, the TEP silencer support and fixing device provided by the present application has a rectangular structure as its base 1, preferably a square structure. The caster assembly 5 includes four universal wheels 51 rotatably connected to the four corners of the bottom surface of the base 1, so that the caster assembly 5 can drive the base 1, the limit bracket 2 and the TEP silencer 100 to move linearly, horizontally or turn, thereby improving the flexibility of the device of the present application to drive the TEP silencer 100 to move, facilitating the rapid adjustment and centering of the first section 101 and the second section 102 after the first section 101 is lifted and separated, and can significantly improve the maintenance and disposal efficiency of the TEP silencer 100.
[0030] Preferably, each universal wheel 51 is also provided with a brake structure (not shown), which can prevent the rotation of the universal wheel 51 in actual use, so that the device of the present application can transfer the TEP silencer 100 to an appropriate position and stop it, making it convenient for operators to perform maintenance on the TEP silencer 100.
[0031] Preferably, the support structure 3 is fixedly mounted at the middle of the top surface of the base 1 and vertically extends to the top to abut against the rounded curved surface of the bottom of the TEP muffler 100 , thereby supporting the bottom of the TEP muffler 100 .
[0032] See also Figure 3 and Figure 5 In a specific embodiment, the support structure 3 includes four bottom support sleepers 31, and the four bottom support sleepers 31 are evenly distributed with the axis of the TEP silencer 100 in the length direction as the center, and the top contour of the bottom support sleeper 31 coincides with the bottom contour of the TEP silencer 100, so that the four bottom support sleepers 31 can stably support the bottom of the TEP silencer 100, and to a certain extent restrict the TEP silencer 100 to maintain a vertical posture, reducing the risk of the TEP silencer 100 tilting or tipping. Moreover, the bottom support sleeper 31 of the device of the present application is a wooden structure, which can be deformed appropriately under pressure to increase the contact area with the round head arc surface at the bottom of the TEP silencer 100, playing a certain role in shock absorption and pressure distribution, reducing the pressure on the bottom of the TEP silencer 100, and avoiding the damage to the bottom of the TEP silencer 100 caused by the hard support. In addition, the bottom support sleeper 31 of the wooden structure is also easier to contour, so that its top can better fit the rounded curved surface of the bottom of the TEP silencer 100.
[0033] Of course, in some other embodiments, the number of the bottom support sleepers 31 may be three or more, and the three bottom support sleepers 31 can support the bottom of the limited TEP muffler 100 in the form of a stable triangle. More bottom support sleepers 31 can increase the contact area with the bottom of the TEP muffler 100, thereby improving the support stability of the bottom of the TEP muffler 100 and preventing the TEP muffler 100 from tilting or falling.
[0034] See also Figure 1 , Figure 3 and Figure 5 In a specific embodiment, the device of the present application also includes an inspection platform 6, which is horizontally fixedly connected to the base 1 and forms a bottom cavity (not marked) between the inspection platform 6 and the base 1. A limiting hole 61 connected to the bottom cavity and located in the limiting bracket 2 is opened in the middle of the inspection platform 6, and the limiting hole 61 is correspondingly located below the limiting structure 4 and is on the same axis as the TEP silencer 100.
[0035] Preferably, the shape and size of the inspection platform 6 match those of the base 1, and both are rectangular structures, and are correspondingly fixedly connected to the top of the base 1 through four fixing columns 62. The support structure 3 is in the bottom cavity and below the limiting hole 61. The aperture of the limiting hole 61 is slightly larger than the lower outer diameter of the TEP muffler 100, so that the lower part of the TEP muffler 100 can be vertically inserted into the bottom cavity through the limiting hole 61, and the rounded arc surface at the bottom of the TEP muffler 100 can be tightly attached and pressed against the support structure 3, which is convenient for supporting and fixing the TEP muffler 100. In addition, the limiting hole 61 of the device of the present application can also support the outer wall of the TEP muffler 100 from the side when the TEP muffler 100 tilts, thereby preventing the TEP muffler 100 from tipping over due to excessive tilting, which is safer.
[0036] The outer area of the limiting hole 61 of the maintenance platform 6 of the device of the present application constitutes a platform for maintenance personnel to stand and perform handling operations on the TEP silencer 100, which is convenient for maintenance personnel to walk around the TEP silencer 100, disassemble and assemble fasteners 104, and separate or assemble the first section 101 and the second section 102 of the TEP silencer 100.
[0037] See also Figure 1 , Figure 3 and Figure 5 In a specific embodiment, the device of the present application further includes a guardrail 7, which is fixedly connected to the maintenance platform 6 and is located outside the limit bracket 2. The guardrail 7 forms a protective structure outside the limit bracket 2 to prevent the operator on the maintenance platform 6 from falling, which is safer.
[0038] Preferably, the guardrail 7 extends along three sides of the maintenance platform 6 to form an opening (not marked) on one side of the maintenance platform 6, and a guardrail door 8 that can be opened and closed is movably connected to the opening to facilitate operators to enter and exit the maintenance platform 6 through the guardrail door 8.
[0039] Preferably, the guardrail door 8 is detachably connected to the guardrail 7 to facilitate assembly and disassembly of the guardrail door 8 and facilitate use.
[0040] See also Figure 1 , Figure 3 and Figure 5 In a specific embodiment, the limiting bracket 2 includes four vertical support columns 21 vertically arranged at the periphery of the limiting hole 61, and four connecting rods 22 horizontally connected between the tops of the vertical support columns 21 and connected end to end. The bottom of the vertical support column 21 penetrates downward through the maintenance platform 6 and is welded and fixed to the base 1. The limiting structure 4 is fixedly connected to the connecting rod 22 and abuts against the side wall of the TEP muffler 100 from the side.
[0041] Preferably, the distance between two adjacent vertical support columns 21 on the same side of the guardrail door 8 is greater than the outer diameter of the lower section of the TEP silencer 100, and the corresponding connecting rod 22 on the same side of the guardrail door 8 is a detachable connecting rod 221. This structural design allows maintenance personnel to form an open structure on the same side of the guardrail 7 and the limit bracket 2 by disassembling the guardrail door 8 and the detachable connecting rod 221, so that the lower section of the TEP silencer 100 can be placed into the limit bracket 2 through one side of the guardrail door 8, which can effectively reduce the lifting height of the TEP silencer 100 during the placement or rotation out process, reduce the difficulty of hoisting the TEP silencer 100, and thereby improve the efficiency of placing the TEP silencer 100 in and out of the device.
[0042] See also Figure 3 Preferably, the limiting structure 4 includes four lateral supporting sleepers 41, which are evenly distributed around the axis of the TEP silencer 100 in the length direction, and the top contour of the lateral supporting sleeper 41 coincides with the contour of the middle side wall of the TEP silencer 100, so that the four lateral supporting sleepers 41 can stably support the middle side wall of the TEP silencer 100, and cooperate with the bottom supporting sleeper 31 to limit the TEP silencer 100, so that it can maintain a vertical posture and be supported and fixed on the device of the present application, effectively preventing the TEP silencer 100 from tilting or falling over.
[0043] Moreover, the lateral support sleeper 41 of the device of the present application is a wooden structure, which can be appropriately deformed under lateral compression and increase the contact area with the side wall of the middle part of the TEP muffler 100, playing a certain role in cushioning and pressure distribution, thereby reducing the pressure on the side wall of the middle part of the TEP muffler 100 and avoiding the damage to the side wall of the TEP muffler 100 caused by the hard support. In addition, the lateral support sleeper 41 of the wooden structure is also easier to shape the contour, so that its top can better fit the contour of the side wall of the middle part of the TEP muffler 100.
[0044] See also Figure 3 and Figure 5 Preferably, the four lateral support sleepers 41 are arranged in a group of two, wherein two lateral support sleepers 41 are fixed on the inner side of the detachable connecting rod 221 facing the TEP silencer 100, and the other two lateral support sleepers 41 are correspondingly fixed on the corresponding connecting rod 22 directly opposite to the detachable connecting rod 221, and are located on the inner side of the corresponding connecting rod 22 facing the TEP silencer 100. This structural design ensures that when the operator removes the detachable connecting rod 221, the remaining limiting structures 4 will not interfere with the TEP silencer 100 being placed in or rotated out of the limiting bracket 2, thereby ensuring that the TEP silencer 100 can be smoothly placed in or rotated out of the device of the present application.
[0045] In actual use, the operator can transfer the device of the present application to the vicinity of the faulty TEP muffler 100 through the caster assembly 5, and after the brake is positioned, the guardrail door 8 and the detachable connecting rod 221 are removed, and the faulty TEP muffler 100 is lifted and transferred to the limit bracket 2 at a relatively low height and parallel to the side of the guardrail door. Then the TEP muffler 100 is lowered so that the bottom of the second section 102 can extend vertically into the bottom cavity through the limit hole 61 until the bottom of the TEP muffler 100 presses against the bottom support sleeper 31. The detachable connecting rod 221 is installed back on the limit bracket 2, and the middle side wall of the TEP muffler 100 is pressed against the lateral support sleeper 41 on the connecting rod 22 to ensure that the TEP muffler 100 is vertically supported and fixed on the device in a posture perpendicular to the ground. After fixing the TEP silencer 100, the guardrail door 8 is installed back on the guardrail 7. After the operator removes the fastener 104 of the TEP silencer 100 on the maintenance platform 6, the first section 101 is lifted and separated from the second section 102. At this time, the second section 102 is still supported and fixed by the device of the present application, and can always be placed in a vertical posture perpendicular to the ground, ensuring that the new gasket can be placed horizontally at the flange of the second section 102. After replacing the new gasket, the first section 101 is lowered and the flange set 103 is aligned, and then the first section 101 and the second section 102 are locked and fixed by the fastener 104 to complete the maintenance of the TEP silencer 100. Finally, the guardrail door 8 and the detachable connecting rod 221 are removed, and the repaired TEP silencer 100 is lifted and rotated out of the device of the present application at a relatively low height and parallel to the side of the guardrail door to complete the maintenance of the TEP silencer 100. The whole operation process is simple and convenient, which improves the efficiency of maintenance and treatment. In addition, the device of the present application has a good supporting and fixing effect on the TEP silencer 100, which effectively avoids the problem of the TEP silencer 100 tilting or falling during the maintenance process.
[0046] See also Figure 3 and Figure 4 In a specific embodiment, the device of the present application also includes a lifting support member 9, which is disposed on the base 1 and can be adjusted in height compared to the base 1, and the lifting support member 9 is configured to be adjustable to support the base 1 and to lift the caster assembly 5 off the ground.
[0047] Preferably, the four corners of the base 1 are provided with fixing parts 11 extending outwards, and each fixing part 11 is vertically fixedly connected with a screw sleeve 12. The lifting support member 9 includes lifting support screws 91 respectively threadedly connected to the corresponding screw sleeves 12, and the bottom of each lifting support screw 91 is fixedly connected with a support seat 92 that can be pressed against the ground.
[0048] In actual use, the operator can adjust the length of the support seat 92 extending toward the ground side compared to the base 1 by screwing the lifting support screw 91, so as to facilitate the operator to adjust the horizontal posture of the base 1 on uneven ground, and ensure that the TEP silencer 100 can always be supported and fixed to the device of the present application in a vertical posture. In addition, the operator can also support the base 1 and lift the caster assembly 5 off the ground by screwing the lifting support screw 91, so as to support the base 1, the limit bracket 2 and the TEP silencer 100 through the lifting support member 9 in static state, increase the load of the device of the present application as a whole, and avoid the caster assembly 5 from being damaged by excessive load when bearing weight.
[0049] The above are only preferred implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
