Description

Technical Field

[0001] The invention relates to the technical field of pipeline supports, and in particular to an earthquake-resistant installation structure for a fire-fighting pipeline. Background Art

[0002] The fire pipe seismic support is a seismic support facility specially used for fire pipe systems. When natural disasters such as earthquakes occur, the fire pipe system is one of the most important lifeline systems, so its stability and safety must be guaranteed. The function of the fire pipe seismic support is to limit the displacement of fire pipe facilities, control the vibration of facilities, and transfer the load to various components or devices on the bearing structure to ensure that the fire pipe system will not break or break under the action of earthquake force, thereby ensuring the normal operation of the fire protection system and protecting people’s lives and property.

[0003] The existing earthquake-resistant installation structure usually uses a boom bracket and a clamp to be directly installed and fixed on the wall with bolts. When it is used in a place with a larger area, due to space limitations, there is usually a situation where the pipes are staggered up and down. In this case, when the pipes vibrate, it is easy to cause vibration transmission to the pipes that are staggered up and down, which reduces the service life of the fire-fighting pipes under vibration and deteriorates their stability. It is impossible to ensure the normal use of the fire-fighting pipes in emergency situations. Therefore, the present application provides a fire-fighting pipe earthquake-resistant installation structure to meet the needs. Summary of the invention

It also includes a fixing component 5, the fixing component 5 is installed at the bottom of the ceiling 1, and the fixing component 5 is used to fix the pipe, a shock absorbing component 6, the shock absorbing component 6 is installed between the fixing component 5 and the ceiling 1, and the shock absorbing component 6 is used to absorb the vibration of the pipe, and an auxiliary component 7, the auxiliary component 7 is respectively installed on one side of the corresponding supporting boom 3, the auxiliary component 7 is located on both sides of the shock absorbing component 6, and the auxiliary component 7 is used to perform auxiliary clamping and protection on the pipe below.

[0043] like Figures 1 to 4 As shown, the fixing assembly 5 includes a telescopic rod 51, which is symmetrically installed at the bottom of the ceiling 1. The telescopic rod 51 is provided with two groups, and a slider 52 is connected between the bottom ends of the two groups of telescopic rods 51. Two fixing rings 53 are symmetrically installed on both sides of the slider 52. A shock-absorbing pad 530 is clamped on the inner side of each fixing ring 53. The slider 52 slides inside the slide grooves of the two fixing rings 53. The bottom ends of the two fixing rings 53 are respectively connected to connecting plates 1 54, which rotate inside the bottom bracket of the fixing ring 53 on the corresponding side. A connecting plate 2 54 is connected between the two connecting plates 1 54. 5. The connecting plate 1 54 rotates on the outer side of the connecting plate 2 55. The outer side of the connecting plate 2 55 is clamped with a mounting frame 56. The mounting frame 56 slides inside the slide groove of the connecting plate 2 55. The bottom end of the mounting frame 56 is connected with a snap ring 57. The snap ring 57 is installed on the mounting plate 4. Two auxiliary brackets 58 are symmetrically connected to the outer side of the mounting frame 56. The auxiliary brackets 58 are installed on the two supporting booms 3 on the corresponding side. The auxiliary brackets 58 slide on the side walls of the supporting booms 3. The ends of the auxiliary brackets 58 are connected with elastic telescopic rods 59. The top ends of the elastic telescopic rods 59 are connected to the bottom of the ceiling 1.

[0044] By providing the fixing assembly 5, during installation, the operator first drives the expansion bolt 2 into the inner side of the ceiling 1 according to the size of the mounting plate 4, fixes one end of the supporting boom 3 on the ceiling 1, clamps the shock-absorbing pad 530 on the inner wall of the fixing ring 53, and places the inner side of the shock-absorbing pad 530 close to the outer wall of the fire-fighting pipe for installation, uses standard bolts to connect the four sliding claws of the slider 52 to the outer side of the slider 52, and makes the slider 52 slide in the slide groove of the fixing ring 53, so that the two fixing rings 53 and the slider 52 are connected as a whole, and uses standard bolts to fix the connecting plate 1 54 and the connecting plate 2 55, and the top of the slider 52 is connected by the telescopic rod 51. The fixing ring 53 is connected to the slider 52, so that the fire-fighting pipe inside the fixing ring 53 and the shock-absorbing pad 530 is pulled and fixed on the ceiling 1 by the telescopic rod 51. The mounting frame 56 sliding on the outside of the connecting plate 2 55 is connected to the supporting boom 3 through the auxiliary bracket 58, so that the mounting frame 56 can have sufficient supporting force to support the fire-fighting pipe located above. At the same time, the end of the auxiliary bracket 58 is connected to the elastic telescopic rod 59, so that the auxiliary bracket 58 can always be subjected to the vertical traction force of the elastic telescopic rod 59 when the pipe falls due to gravity, so as to provide a buffer for the fire-fighting pipe in a strong earthquake and reduce the pipe being subjected to excessive force. In order to prevent the fire-fighting pipes from being squeezed, deformed and damaged, the integrity of the pipes can be guaranteed as much as possible during an earthquake. The mounting plate 4 is connected to the bottom of the four supporting booms 3 with bolts. The clamping ring 57 clamps the fire-fighting pipe located below. The bottom of the clamping ring 57 is fixed to the mounting plate 4 with bolts. When the fire-fighting pipes are cross-laid in multiple layers, the fire-fighting pipes are fixed by the supporting force provided by the supporting booms 3 and the telescopic rods 51. At the same time, each layer of fire-fighting pipes can provide interaction force with each other. By using rubber material for the shock-absorbing pads 530 and the clamping rings 57, the resonance between the fire-fighting pipes is reduced when the fire-fighting pipes vibrate, thereby ensuring the installation stability of the fire-fighting pipes.

[0045] like Figures 5 to 8As shown, the shock absorbing assembly 6 includes a traction rod 61, which is installed at the bottom of the ceiling 1, and the end of the traction rod 61 is connected to a piston plate 1 62, and a storage barrel 63 is sleeved on the outer side of the piston plate 1 62. The piston plate 1 62 slides on the inner side of the storage barrel 63, and the bottom of the piston plate 1 62 is connected to a liquid orifice plate 64, and the bottom end of the liquid orifice plate 64 is connected to a piston plate 2 65, and the piston plate 2 65 slides on the inner side of the storage barrel 63. The bottom of the piston plate 2 65 is connected to a spring 66, and the surfaces of the piston plate 1 62 and the piston plate 2 65 are provided with tooth blocks 67. The storage barrel 63 is connected to an oil box 1 68 through a pipeline near the upper outer side. The oil box 1 68 is installed on the outside of the mounting frame 56, and the storage barrel 63 is connected to the oil box 2 69 near the lower outside through a pipeline. The oil box 2 69 is installed on the outside of the mounting frame 56. The inner side of the oil box 1 68 is nested with a push rod 1 610, and the push rod 1 610 slides on the inner side of the oil box 1 68. The inner side of the oil box 2 69 is nested with a push rod 2 611, and the push rod 2 611 slides on the inner side of the oil box 2 69. The bottom of the storage barrel 63 is connected to a connecting plate 3 612, and the connecting plate 3 612 rotates at the bottom of the storage barrel 63. The end of the connecting plate 3 612 is connected to the top of the slider 52, and the end of the connecting plate 3 612 rotates on the top of the slider 52.

[0046] By providing a shock absorbing assembly 6, the fire-fighting pipe located above is connected to the ceiling 1 through the telescopic rod 51. During an earthquake, the fire-fighting pipe located above will resonate with the building body. When the fire-fighting pipe vibrates, the expansion bolt 2 and the supporting boom 3 provide supporting force for the mounting plate 4 to prevent the fire-fighting pipe located below from directly falling off due to the vibration, which would render the building emergency facilities unusable. When a shock wave is generated, the connecting plate three 612 rotates on the top of the slider 52 during the vibration, causing the storage barrel 63 to swing. Since the traction rod 61 passes through the top of the storage barrel 63 and is connected to the top of the piston plate one 62, when the storage barrel 63 moves downward during the swing, the piston plate one 62 squeezes the oil at the top of the storage barrel 63, and the tooth surface portion of the piston plate one 62 and the tooth block 67 located above inside the storage barrel 63 are vertically engaged and slid with each other. The unengaged part of the tooth surface of the tooth block 67 and the piston plate 62 is in contact with the oil, and the gap of the tooth block 67 is filled with oil, and the vibration force enters the oil through conduction. At the same time, the liquid orifice plate 64 connected to the bottom end of the piston plate 62 is sliding in the storage barrel 63, and the oil passes through the holes in the liquid orifice plate 64, which can further conduct the vibration force into the oil, so that no resonance force is generated between the fire-fighting pipes due to vibration. The spring 66 is in a stretched state at the bottom end of the piston plate 65. At the same time, it can reduce the impact of vibration on other fire-fighting pipes. The oil enters the oil box 68 through the connecting pipeline. In the initial state, there is oil in the oil box 68. The oil pushes the push rod 610 in the oil box 68, so that the push rod 610 slides inside the oil box 68, and pushes the sliding wheel 76 to slide on the block 77 part of the connecting shaft 71.

[0047] like Figures 9 to 12As shown, the auxiliary component 7 includes a connecting shaft 71, both ends of the connecting shaft 71 are nested in the inner side of the mounting frame 56, two groups of slots 72 are symmetrically arranged on the outer side of the connecting shaft 71, and a contact wheel 73 is sleeved on the outer side of the slot 72. The contact wheel 73 is connected to the slot 72 through a fixing pin 74, and the contact wheel 73 swings along the fixing pin 74 as the center of the circle on the outer side of the slot 72. A contact rod 730 is nested in the inner side of the contact wheel 73, and the contact rod 730 is installed at the bottom of the connecting plate 2 55. One end of the contact wheel 73 is connected to a connecting plate 4 75, and one end of the connecting plate 4 75 rotates on the inner side of the end bracket of the contact wheel 73. The connecting plate 4 75 The tail end of the connecting plate 75 is connected to a sliding wheel 76, and the tail end of the connecting plate 75 rotates on the inner side of the end bracket of the sliding wheel 76. Blocks 77 are symmetrically provided on the outer side of the connecting shaft 71. The sliding wheel 76 slides on the outer side of the block 77. The bottom of the sliding wheel 76 is connected to a rack rack 78, and the rack rack 78 slides in the bottom slide groove of the mounting frame 56. The rack parts of the rack rack 78 are respectively meshed with gears 79, and the gear 79 rotates on the bracket of the mounting plate 4. The end of the gear 79 is connected to a bevel gear set 710, and the bevel gear set 710 rotates on the bracket of the mounting plate 4. A clamping claw 711 is connected to the output end of one of the bevel gears in the bevel gear set 710.

[0048] By providing the auxiliary component 7, when the fire-fighting pipe located above vibrates, since the slider 52 slides in the sliding grooves on both sides of the fixed ring 53, the vibration wave will be transmitted to the fixed ring 53 through contact. When the position of the slider 52 remains unchanged, the fixed ring 53 swings according to the strength of the vibration wave on the corresponding side, so that the connecting plate 1 54 rotates on the outside of the fixed ring 53. Since the mounting frame 56 is fixed between the two sets of auxiliary brackets 58, the sliding part of the mounting frame 56 in the sliding groove of the connecting plate 2 55 acts as a supporting slide rail according to the strength of the vibration wave on the corresponding side, so that the connecting plate 2 55 slides to the corresponding side under the drive of the connecting plate 1 54, and the contact rod 730 moves accordingly. At the same time, the contact rod 730 pushes the contact wheel 73 to swing in the same direction around the fixed pin 74, and pushes the sliding wheel 76 on the connecting shaft 71 through the push rod 1 610 to slide inside the oil box 1 68. The block 77 part slides, the connecting plate 4 75 rotates at the end of the sliding wheel 76, pulling the contact wheel 73, causing the contact wheel 73 to swing around the fixing pin 74 on the outside of the slot 72. At the same time, the sliding wheel 76 drives the push rod 2 611 to move during the sliding, and the contact wheel 73 returns to the initial vertical state, so that the push rod 2 611 is moved through the negative pressure generated in the oil box 2 69, and the oil is sucked back from the storage barrel 63 located below the piston plate 2 65 through the pipeline to the inside of the oil box 2 69, and the storage barrel 63 moves upward, and the spring 66 returns to its original state, reducing the resonance of the fire-fighting pipe during vibration. At the same time, the sliding wheel 76 drives the rack rack 78 to slide during the sliding, and meshes with the gear 79, and the gear 79 drives the bevel gear set 710 to mesh and rotate, so that the clamping claw 711 clamps the lower pipe, reducing the influence of the vibration of the upper pipe on the lower pipe.

[0049] The working principle of the technical solution provided by the present invention is as follows:

[0050] During installation, the operator first drives the expansion bolt 2 into the inner side of the ceiling 1 according to the size of the mounting plate 4, fixes one end of the support arm 3 on the ceiling 1, clamps the shock-absorbing pad 530 on the inner wall of the fixing ring 53, and places the inner side of the shock-absorbing pad 530 close to the outer wall of the fire-fighting pipe for installation, uses standard bolts to connect the four sliding claws of the slider 52 to the outer side of the slider 52, and makes the slider 52 slide in the slide groove of the fixing ring 53, so that the two fixing rings 53 and the slider 52 are connected as a whole, and uses standard bolts to fix the connecting plate 1 54 and the connecting plate 2 55, and the top of the slider 52 is connected through the telescopic rod 51. The fixing ring 53 is connected to the slider 52, so that the fire-fighting pipe inside the fixing ring 53 and the shock-absorbing pad 530 is pulled and fixed on the ceiling 1 by the telescopic rod 51. The mounting frame 56 sliding on the outside of the connecting plate 2 55 is connected to the supporting boom 3 through the auxiliary bracket 58, so that the mounting frame 56 can have sufficient supporting force to support the fire-fighting pipe located above. At the same time, the end of the auxiliary bracket 58 is connected to the elastic telescopic rod 59, so that the auxiliary bracket 58 can always be subjected to the vertical traction force of the elastic telescopic rod 59 when the pipe falls due to gravity, so as to provide a buffer for the fire-fighting pipe in a strong earthquake and reduce the pipe being subjected to excessive force. In order to prevent the fire-fighting pipes from being squeezed, deformed and damaged, the integrity of the pipes can be guaranteed as much as possible during an earthquake. The mounting plate 4 is connected to the bottom of the four supporting booms 3 with bolts. The clamping ring 57 clamps the fire-fighting pipe located below. The bottom of the clamping ring 57 is fixed to the mounting plate 4 with bolts. When the fire-fighting pipes are cross-laid in multiple layers, the fire-fighting pipes are fixed by the supporting force provided by the supporting booms 3 and the telescopic rods 51. At the same time, each layer of fire-fighting pipes can provide interaction force with each other. By using rubber material for the shock-absorbing pads 530 and the clamping rings 57, the resonance between the fire-fighting pipes is reduced when the fire-fighting pipes vibrate, thereby ensuring the installation stability of the fire-fighting pipes.

[0051] Since the fire-fighting pipe located at the top is connected to the ceiling 1 through the telescopic rod 51, the fire-fighting pipe located at the top will resonate with the building body during an earthquake. When the fire-fighting pipe vibrates, the expansion bolt 2 and the supporting boom 3 provide support for the mounting plate 4 to prevent the fire-fighting pipe located below from falling off directly due to the vibration, which would render the building emergency facilities unusable. When a shock wave is generated, the connecting plate three 612 rotates on the top of the slider 52 during vibration, causing the storage barrel 63 to swing. Since the traction rod 61 passes through the top of the storage barrel 63 and is connected to the top of the piston plate one 62, when the storage barrel 63 moves downward during the swing, the piston plate one 62 squeezes the oil at the top of the storage barrel 63, and the tooth surface portion of the piston plate one 62 and the tooth block 67 located above inside the storage barrel 63 are vertically engaged and slid with each other, and the tooth block 67 The unengaged part of the tooth surface of the piston plate 62 is in contact with the oil, and the gap of the tooth block 67 is filled with oil, and the vibration force enters the oil through conduction. At the same time, the liquid orifice plate 64 connected to the bottom end of the piston plate 62 is sliding in the storage barrel 63, and the oil passes through the holes in the liquid orifice plate 64, which can further conduct the vibration force into the oil, so that no resonance force is generated between the fire-fighting pipes due to the vibration. The spring 66 is in a stretched state at the bottom end of the piston plate 65. At the same time, it can reduce the impact of vibration on other fire-fighting pipes. The oil enters the oil box 68 through the connecting pipeline. In the initial state, there is oil in the oil box 68. The oil pushes the push rod 610 in the oil box 68, so that the push rod 610 slides inside the oil box 68, and pushes the sliding wheel 76 to slide on the block 77 of the connecting shaft 71.

[0052] When the fire-fighting pipe located above vibrates, since the slider 52 slides in the sliding grooves on both sides of the fixed ring 53, the vibration wave will be transmitted to the fixed ring 53 through contact. When the position of the slider 52 remains unchanged, the fixed ring 53 will swing according to the strength of the vibration wave on the corresponding side, so that the connecting plate 1 54 rotates on the outside of the fixed ring 53. Since the mounting frame 56 is fixed between the two sets of auxiliary brackets 58, the sliding part of the mounting frame 56 in the sliding groove of the connecting plate 2 55 can be used as a supporting slide rail to make the connecting plate 2 55 slide to the corresponding side under the drive of the connecting plate 1 54, and the contact rod 730 moves accordingly. At the same time, the contact rod 730 pushes the contact wheel 73 to swing in the same direction around the fixed pin 74, and pushes the sliding wheel 76 to the block 77 part of the connecting shaft 71 through the push rod 1 610 to slide inside the oil box 1 68. The second cam 73 is in the state of being rotated by the second cam 73, and the second cam 73 is in the state of being rotated by the second cam 73.
