Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fireproof and heat-insulating materials for bridges, and in particular to a production equipment for heat-insulating materials for the main cable of a bridge. Background Technology
[0002] As the core hub of modern transportation networks, bridges play an irreplaceable role in promoting regional economic development and ensuring the smooth operation of society. The number of long-span cable-stayed bridges in service and under construction in China is increasing. With the improvement of living standards, the number of various vehicles (trolleybuses, freight trucks, and hazardous materials transport vehicles) has been increasing year by year, leading to a rise in vehicle-related fires on bridges. This has gradually become a new type of hazard for long-span bridges, prompting fire prevention and insulation technology to become an important research direction in the field of bridge engineering.
[0003] As the main load-bearing system of modern bridges, steel structures face a significant risk of performance degradation in high-temperature environments. Steel suffers irreversible damage at 300℃, its strength decreases by 50% at 400℃, and it almost completely loses its load-bearing capacity at 600℃.
[0004] The existing thermal insulation material for the main cable of the bridge consists of high-silica oxygen gel felt, cloth, and acrylic adhesive, and is produced through two processes: sewing and bonding. The sewing process is done by sewing machine, while the bonding process is done manually, which is inefficient. In addition, the thermal insulation material is quite long and needs to be fully laid out during bonding, occupying a lot of space. Utility Model Content

[0024] Figure 1 This is a schematic diagram of the present invention.
[0025] Figure 2 This is a schematic diagram showing the engagement state of the first gear and the second gear of this utility model. Detailed Implementation
[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0027] See Figure 1 and Figure 2 A production equipment for thermal insulation material of bridge main cable includes an operating table 1, a first roller 2, a second roller 3, a third roller 4, a fourth roller 5, and a fifth roller 6.
[0028] The worktable 1 is used to place the material to be processed 9, such as high-silica oxygen gel felt and cloth. As mentioned in the background art, the high-silica oxygen gel felt and cloth can be sewn together by a sewing machine and then placed on the worktable to bond them with tape, which can be acrylic adhesive.
[0029] In one embodiment, the operating table 1 is divided into left and right parts, with the upper surfaces of the left and right parts being flush and used to arrange high-silica oxygen gel felt and cloth. A gap is left between the left and right parts to accommodate the first roller 2.
[0030] The first roller 2 is mounted on the first bracket (not shown in the figure). After installation, its upper edge is flush with or slightly higher than the upper surface of the operating table 1. It is only necessary to ensure that it can drive the material to be processed along the upper surface of the operating table when it rotates.
[0031] The first support can be placed on the ground like the control panel 1, or it can be part of the control panel, or it can be fixed on the support of the control panel 1.
[0032] In this embodiment, the first roller shaft 2 is connected to the motor 72 via the transmission unit 71. After the motor 72 is started, the first roller shaft 2 rotates, thereby driving the material to be processed forward.
[0033] In one embodiment, the motor 72 can be fixed on the bottom support of the operating table 1. The transmission unit 71 includes a first sprocket mounted on the first roller shaft 2, a second sprocket mounted on the motor 72, and a chain wound around the first sprocket and the second sprocket. Specifically, the first sprocket is fixedly mounted on the left end of the first roller shaft 2 and can be exposed on the side of the operating table 1. The first sprocket rotates synchronously with the first roller shaft 2. The second sprocket is fixed on the outer end of the output shaft of the motor 72 and located directly below the first sprocket. The two are then connected by a chain. The first sprocket, the second sprocket, and the chain can refer to existing designs.
[0034] The second roller 3 has a roll of adhesive tape mounted on it and installed on a second bracket (not shown in the figure). The second bracket can be placed on the ground like the operating table 1, or it can be part of the operating table 1, or it can be fixed to the bracket of the operating table 1. The roll of adhesive tape is made of adhesive tape 81, specifically, it is made of acrylic adhesive tape. For example, the acrylic adhesive tape can be wound onto the second roller 3, or the acrylic adhesive tape can be wound into a roll and then fitted onto the second roller 3.
[0035] Because the acrylic adhesive has a protective paper 82, the adhesive surface is exposed only after the protective paper 82 is torn off. Therefore, in this embodiment, a third roller 4 is designed for tearing off the protective paper 82 of the tape. Specifically, the third roller 4 is installed on a third bracket (not shown in the figure). The third bracket can be placed on the ground like the operating table 1, or it can be part of the operating table 1, or it can be fixed on the bracket of the operating table 1.
[0036] In actual operation, one end of the protective paper 82 can be fixed to the third roller 4, and the third roller 4 can be rotated by the drive mechanism to wind the protective paper and tear the protective paper 82 off the tape; or a component that can pull the protective paper 82 can be added, with the protective paper 82 only wound around the third roller 4, and the driving force for pulling the protective paper is provided by this component, which can be a roller driven by a motor, with the outer end of the protective paper fixed to the roller.
[0037] The second roller 3 is arranged above the first roller 2, and the third roller 4 is arranged above the second roller 3. In one embodiment, the third roller 4 can also be arranged on the left side of the first roller 2 to ensure that the protective paper 82 can be easily torn off the tape.
[0038] The fourth roller 5 is mounted on the fourth bracket (not shown in the figure) and arranged above the material to be processed. In one embodiment, it is arranged longitudinally between the first roller 2 and the second roller 3, and is located directly above the first roller 2. The second roller 3 is arranged to the right of the first roller 2.
[0039] The fourth bracket can be placed on the ground like the control panel 1, or it can be part of the control panel 1, or it can be fixed on the bracket of the control panel 1.
[0040] After the material to be processed is placed on the operating table 1, a gap is still reserved between the fourth roller 5 and the material to be processed located below it to allow the tape to pass through. The fourth roller 5 is used to apply adhesive pressure so that the tape adheres to the material to be processed.
[0041] In this embodiment, a first gear 21 is fixedly provided on the right end of the first roller shaft 2, and a second gear 51 that meshes with the first gear 21 is fixedly provided on the corresponding end of the fourth roller shaft 5, so that the fourth roller shaft 5 rotates when the first roller shaft 2 rotates, thereby improving the bonding effect.
[0042] In one embodiment, the fourth support is provided with a lifting device (not shown in the figure) for adjusting the height of the fourth roller 5, which can realize a small amount of movement of the fourth roller 5 in the vertical direction to adjust the bonding pressure, and at the same time can adapt to the bonding of high silica oxygen gel felt and cloth of different thicknesses.
[0043] For the lifting device, existing designs that can adjust the height of the roller shaft can be referenced. For example, the lifting device includes a lead screw arranged longitudinally on the fourth support and a nut connected to the lead screw. The nut is fixed on the connecting block at the end of the fourth roller shaft, the connecting block is slidably set on the fourth support, and a handwheel is installed at the upper end of the lead screw.
[0044] In this embodiment, a fifth roller 6 is provided in front of the fourth roller 5. The fifth roller 6 is mounted on the fifth bracket (not shown in the figure). The fifth bracket can be placed on the ground like the operating table 1, or it can be part of the operating table 1, or it can be fixed on the bracket of the operating table 1.
[0045] The tape 81 of the tape roll is arranged between the fourth roller 5 and the material to be processed after passing through the fifth roller 6. Furthermore, the fifth roller 6 is provided with a limiting plate 61 for limiting the tape. As one option, the limiting plate 61 is in the shape of a ring and is arranged circumferentially on the fifth roller 6. Of course, corresponding limiting plates 61 can be provided at both the left and right ends of the fifth roller 6 to limit the tape 81 between the two limiting plates 61.
[0046] like Figure 1 As shown, the outer end of the tape 81 is pulled out from the second roller 3, passes through the fifth roller 6, and is arranged below the fourth roller 5 and above the material to be processed 9. The protective paper 82 of the tape 81 is torn off the tape and wrapped around the third roller 4. After the motor drives the first roller 2 to rotate, it drives the material to be processed 9 to move forward along the upper surface of the operating table 1. At the same time, the fourth roller 5 provides pressure to make the tape 81 adhere to the material to be processed 9. During the forward movement of the material to be processed 9, the tape 82 is automatically adhered from one end of the material to be processed 9 to the other end, so that the entire surface of the material to be processed 9 is adhered with tape 82, thus obtaining the thermal insulation material for the main cable of the bridge, which replaces the manual operation method in the prior art.
[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
