Description

Technical Field

[0001] The invention belongs to the technical field of pipeline valve port stabilization, and in particular relates to an adjustable non-standard support and hanger. Background Art

[0002] In Shenghong Refining and Chemical's 16 million tons / year integrated refining and chemical project, the catalyst regeneration system of the 1# continuous reforming unit of the aromatics business unit needs to be back-blown online due to the blockage of the reduction tank tail hydrogen outlet filter screen. The first pneumatic valve at the reduction tank tail hydrogen outlet has been repeatedly opened and closed, resulting in large vibration displacement at the hand valve. At present, the valve stem packing has leaked, and there is a risk of hydrogen ignition or explosion. In order to deal with the problem of severe vibration of the valve during backblowing, a temporary bracket is installed to fix the pneumatic valve head of the valve. However, the device often adjusts the load and reaction temperature. Under normal operating conditions, the reduction tank and pipeline produce an upward thermal displacement of 500mm. If the device is suddenly shut down or cooled, the fixed bracket cannot move up and down to compensate for the thermal displacement. At this time, the fixed bracket will cause pipeline tearing and equipment hidden dangers, posing a great risk to the stable operation of the device.

[0003] In view of the above situation, it is necessary to add a bracket at the pneumatic valve head of the first ball valve at the tail hydrogen outlet of the reduction tank. Once an emergency occurs in the device, timely adjustment and compensation can be made. After market research, the use of fixed brackets and spring brackets are not suitable for this working condition. Therefore, a non-standard support bracket is designed to meet on-site needs. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an adjustable non-standard support bracket to solve the problem that the fixed bracket and the spring bracket cannot compensate for the thermal displacement of the pneumatic valve on the reduction pipeline.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0010] A buffer assembly is arranged on the suspension beam, and an intermediate pulley connected to the steel wire rope is arranged at the lower end of the buffer assembly for buffering the violent tension and relaxation of the steel wire rope.

[0012] Preferably, a sleeve sleeved on the slide rod is slidably inserted into the end of the outer cylinder, and the upper end of the sleeve is slidably abutted against the upper end of the slide rod, and the lower end of the sleeve extends out of the outer cylinder and is fixedly connected with a nut.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] See also Figure 1 - Figure 6 As shown, an adjustable non-standard support and hanger comprises:

[0030] A hanging beam 1 is arranged above the valve to be stabilized, the hanging beam 1 is connected to a diverting pulley 2, and the diverting pulley 2 is connected to a steel wire rope 3 for transmitting tension;

[0031] A connecting line, connected to one end of the steel wire rope 3 and connected to the valve, for pulling up the valve;

[0032] A weight 6 is arranged at the other end of the steel wire rope 3 and connected to the steel wire rope 3 through a pull rod 5, and is used to apply a traction force to the steel wire rope 3;

[0033] The buffer assembly 12 is arranged on the suspension beam 1 , and an intermediate pulley 13 connected to the steel wire rope 3 is arranged at the lower end of the buffer assembly 12 for buffering the violent tension and relaxation of the steel wire rope 3 .

[0034] As can be seen from the above, by setting the hanging beam 1, the steering pulley 2, the wire rope 3, the connecting line, the weight 6, the buffer assembly 12 and the intermediate pulley 13, one end of the wire rope 3 is connected to the pneumatic valve to be stabilized through the connecting line, and the other end is connected to the weight 6. The gravity of the weight 6 is converted into an upward pulling force on the connecting line after being transmitted through the wire rope 3 and the steering pulley 2. The upward pulling force of the connecting line can effectively prevent the pneumatic valve from vibrating. When the pneumatic valve generates thermal displacement due to operation, the pneumatic valve will drag the weight 6 to move through the connecting line and the wire rope 3. No matter how the weight 6 moves, it will apply an upward pulling force to the pneumatic valve to maintain the normal operation of the pneumatic valve, which can effectively solve the defect that the fixed bracket cannot compensate for the thermal displacement of the pneumatic valve. At the same time, the buffer assembly 12 can effectively alleviate the sudden tension of the wire rope 3 caused by the drastic change of the working condition, effectively reduce the impact of the tension force on the wire rope 3, avoid the wire rope 3 from breaking during operation, and improve the stability of the entire non-standard fixed bracket.

[0035] The buffer assembly 12 includes an outer cylinder 121 fixedly mounted on the suspension beam 1 and a slide rod 124 slidably inserted at the end of the outer cylinder 121, the lower end of the slide rod 124 is connected to the intermediate pulley 13, a spring 125 is arranged inside the outer cylinder 121, and the two ends of the spring 125 are respectively abutted against the inner wall of the outer cylinder 121 and the end of the slide rod 124, a friction rod 126 is fixedly connected to the inner wall of the outer cylinder 121, and a socket for inserting the friction rod 126 is opened at the end of the slide rod 124, and the friction rod 126 is in close contact with the inner wall of the socket.

[0036] When the pipeline working condition changes dramatically and causes the pneumatic valve to shrink significantly due to thermal displacement, the pneumatic valve will drag the weight 6 upward through the connecting line and the wire rope 3. Since the weight 6 is heavy, both ends of the wire rope 3 are subjected to tension at this time, so that the already taut wire rope 3 is tightened again, and the tightened wire rope 3 will apply pressure to the slide bar 124 through the middle pulley 13, and the slide bar 124 will retract into the inner compression spring 125 of the outer tube 121. At this time, the slide bar 124 and the friction rod 126 rub against each other, Part of the kinetic energy of the rod 124 is converted into frictional heat energy of the friction rod 126. As the sliding rod 124 moves upward, the wire rope 3 obtains a certain buffer space to prevent the wire rope 3 from breaking during the instantaneous tensioning process. During this process, the weight block 6 gradually rises. As the weight block 6 rises, the compressed spring 125 releases its elastic potential energy. At this time, the sliding rod 124 and the friction rod 126 slide and rub again, converting the elastic potential energy of the spring 125 into heat energy for release, thereby achieving effective protection of the wire rope 3.

[0037] The end of the outer cylinder 121 is slidably inserted with a sleeve 122 sleeved on the sliding rod 124, and the upper end of the sleeve 122 is slidably abutted against the upper end of the sliding rod 124, and the lower end of the sleeve 122 extends out of the outer cylinder 121 and is fixedly connected with a nut 123. The user can adjust the buffer distance of the buffer assembly 12 according to the working conditions. When the buffer distance needs to be increased, the nut 123 can be rotated to drive the sleeve 122 to slide and displace inside the outer cylinder 121, so that the space where the spring 125 is located becomes higher and larger, which means that the spring 125 has a longer compression distance, thereby achieving an increase in the buffer distance.

[0038] The outer wall of the outer cylinder 121 is provided with a plurality of heat dissipation holes 127 for dissipating heat. External air can flow from the heat dissipation holes 127 into the inner part of the outer cylinder 121 and contact the slide bar 124 and the friction bar 126 , so that the heat of the slide bar 124 and the friction bar 126 is quickly dissipated.

[0039] The connecting line includes a plurality of suspension wires 4 fixedly connected to the end of the steel wire rope 3, and the suspension wires 4 are connected to the valve to be stabilized through a suspension ring. For example, the number of suspension wires 4 can be set to three, so that the three suspension wires 4 are pulled in a triangle at three locations of the pneumatic valve to be stabilized, which can make the force on the starting valve more uniform and, to a certain extent, can make the pneumatic valve more stable.

[0040] A plurality of insertion rods 8 are slidably inserted on the weight block 6, and the lower ends of the plurality of insertion rods 8 are connected to a mounting plate 7 fixed to the ground. A plurality of slots 9 are provided on the insertion rods 8. A pull plate 10 is provided on the side wall of the weight block 6, and a limit rod 11 slidably inserted inside the weight block 6 is connected to the side wall of the pull plate 10. The pull plate 10 and the limit rod 11 are not always inserted inside the weight block 6, and the limit rod 11 is inserted inside the slot 9.

[0041] When the operator needs to adjust the buffer distance of the buffer assembly 12, in order to prevent the gravity of the weight block 6 from tightening the wire rope 3 and affecting the buffer assembly 12, the limit rod 11 can be inserted into the weight block 6. The limit rod 11 inserted into the weight block 6 will be inserted into the slot 9 of the insertion rod 8. At this time, the limit rod 11 cooperates with the insertion rod 8 to limit the position of the weight block 6 and prevent the weight block 6 from sliding on the insertion rod 8. At this time, the wire rope 3 is no longer pulled by the gravity of the weight block 6, and will not apply pressure to the buffer assembly 12 through the intermediate pulley 13, which is convenient for the operator to adjust the buffer distance of the buffer assembly 12.

[0042] Under normal working conditions, the pipeline will produce an upward thermal displacement of 500 mm. To ensure that the weight block 6 can move a sufficient distance, the sliding process of the weight block 6 on the insertion rod 8 is greater than 500 mm. The insertion rod 8 also limits the shaking of the weight block 6 to a certain extent, thereby increasing the safety of the use of the weight block 6.

[0043] In order to ensure that the pneumatic valve can be subjected to a sufficiently large upward traction force to stabilize the pneumatic valve and prevent it from shaking, the mass of the weight block 6 is three hundred and eighty kilograms.
