Description
Technical Field
[0001] The invention relates to the field of production of a glass fiber reinforced plastic cylinder for a concrete chimney, and in particular to a glass fiber reinforced plastic cylinder winding device and a winding installation method. Background Art
[0002] In the technical field of installing glass fiber reinforced plastic cylinders (i.e. FRP) for corrosion protection of concrete chimneys in China, glass fiber composite materials are widely used in various fields due to their strong corrosion resistance and high plasticity. At present, there are many reliable cases of installing glass fiber reinforced plastic inner cylinders in concrete chimneys of power plants in China.
[0003] In the current process, the winding machine integrates the mold and the drive device to rotate the mold. After molding, the product is demolded from the mold and then installed. The production of the anti-corrosion FRP cylinder of the concrete chimney requires the construction of a temporary plant (about 150-400 square meters) on site. The equipment for processing the FRP inner cylinder generally uses a vertical winding machine. The winding process requires waiting for the curing time, adding steel hoops, demolding with a car crane, turning the cylinder, moving, etc., and the average processing period takes about 2-3 days. The finished FRP cylinder needs to be stored on site (about 1,000 square meters). The site has certain limitations. Open-air storage in the wind and sun will affect the quality of the FRP cylinder.
[0004] There are two installation processes for FRP tube installation, namely hanging type and free-standing type. The hanging type is generally suitable for the anti-corrosion of newly built chimneys. When designing newly built chimneys, the manhole door is designed to be larger than the size of the FRP inner tube. The prefabricated FRP inner tube is transported to the inside of the chimney through the manhole door and lifted to the top of the chimney with multiple jacks to connect with the top steel structure ring beam. Then, each section is connected by hand-pasted FRP to increase strength and sealing. The connection process has high requirements and requires special equipment and multiple people to complete the entire construction process, which takes a long time.
[0005] The self-supporting type is suitable for the anti-corrosion transformation of old chimneys. A lifting device is set at the top of the chimney. The installation time of the lifting device is about 10 days and the removal time is about 7 days, which is high-risk. The lifting device will lift the FRP inner tube stored on the ground to the top of the chimney. The lifting device will lift the FRP inner tube to the top of the chimney. The FRP inner tube that the lifting device lifts to the top of the chimney will be lowered into the chimney from the smoke outlet at the top of the chimney and placed on the prefabricated steel structure ring beam. The quick installation joint set at the bottom of the FRP inner tube is used to connect the adjacent FRP inner tube sections in sequence. The connection process includes hand paste, external glue injection, and steel clamp bolt connection and fixing to increase strength and sealing. Repeat the above steps until all FRP inner tubes are installed in the chimney. Due to the weather during lifting, there is a lot of rain in the south and strong wind in the north. Sometimes it cannot be lifted for several consecutive days. The construction requires the cooperation of many people to complete the entire construction process, and the construction period is relatively long.
[0006] Chinese patent CN104631897A discloses a method for quickly installing a chimney fiberglass inner tube. After the chimney fiberglass inner tube is manufactured in a workshop, it is hoisted into the chimney to realize the installation of the peeled steel inner tube. However, this setting method requires the installation of hoisting equipment from the hoisting part to the top of the chimney. The hoisting distance is relatively long, and the installation and disassembly cycle is also long, which will consume a lot of manpower and material resources and a long production cycle. Summary of the invention
[0007] In view of the above technical problems, the present invention proposes a glass fiber composite material winding machine and a winding installation method. The glass fiber composite material winding machine is used to prepare a glass fiber reinforced plastic cylinder, which is particularly suitable for the renovation of old chimneys and the anti-corrosion of new chimneys.
[0008] This is achieved through the following technical means:
[0009] A glass fiber composite material winding machine comprises a central shaft 1, a material table 2, a sliding track 3, a wire winding frame 4, a supporting wheel 5, a slewing support bearing 6, a driving device 7, a supporting frame 81, a mold 8 and a supporting connecting ring 9.

Two rows of through holes are longitudinally opened on the porous limiting plate. One end of the porous limiting plate is slidably connected to the sliding track 3 through a pulley, and the other end is connected to the arc frame 42 through the steel bracket 43. The arc frame is used to pass the material and wind the material onto the mold 8.
[0017] A production and installation method for adding a glass fiber reinforced plastic cylinder to a chimney is carried out using the above-mentioned glass fiber composite material winding machine, and specifically comprises the following steps:
[0018] 1) Remove and clean the anti-corrosion structure inside the chimney, and make a steel structure foundation to support the installation of the fiberglass cylinder.
[0019] 2) Installation Step 1) A prefabricated steel structure foundation is provided with a support platform ring beam 10 on the steel structure, and the support platform ring beam 10 is used to support the glass fiber composite material winding machine.
[0020] 3) The support connecting ring 9 is fixedly installed on the support platform ring beam 10, and the fiberglass composite material is mechanically hoisted and installed on the upper part of the support platform ring beam 10 by using the chimney top hoisting equipment, and the materials required for production are arranged on the material platform 2.
[0021] 4) Start the driving device 7 to drive the material platform and the track and drive the wire winding frame 4 to rotate together. The glass fiber and auxiliary materials slide up and down repeatedly around the mold 8 on the vertical sliding track 3 through the wire winding frame 4 to arrange the first section of the fiberglass cylinder on the outer layer of the mold 8.
[0022] 5) After the first section of the FRP cylinder in step 4) is processed and completely solidified, a reinforcement layer 12 is wrapped around the bottom of the FRP cylinder and the top of the support platform ring beam 10. The reinforcement layer 12 is a sealing layer of fiber composite material to ensure that the connection between the bottom of the FRP cylinder and the support platform ring beam 10 is sealed to form a closed whole.
[0023] 6) Demolding is performed by hoisting equipment at the top of the chimney, and the fiberglass composite material winding machine is lifted to the upper part of the first section of the fiberglass reinforced plastic cylinder obtained in step 5), and the supporting connecting ring 9 is installed above the inner wall of the first section of the fiberglass reinforced plastic cylinder.
[0024] 7) Repeat steps 4), 5) and 6) multiple times to produce the remaining multi-section FRP cylinders until all the FRP cylinders are produced, wherein when repeating step 5), the reinforcing layer 12 is replaced by a reinforcing layer 12 arranged below the produced FRP cylinder and above the FRP cylinder below it; during the repetitive process, an anti-sway device 14 is installed every 20 to 40 meters, and the anti-sway device 14 includes an anti-sway component 141, a FRP cylinder support ring 142 and a connecting bolt 143; the anti-sway component 141 and the FRP cylinder support ring 142 are connected by a connecting bolt 143, and the FRP cylinder support ring 142 is sleeved on the outside of the FRP cylinder, one end of the anti-sway component 141 is connected to the FRP cylinder support ring 142 by a connecting bolt 143, and the other end is connected to the inside of the chimney, and the anti-sway device 14 is used to prevent the FRP cylinder from shaking.

[0026] Preferably, the anti-sway component 141 is a plurality of connecting brackets.
[0027] Preferably, the reinforcing layer 12 is made of glass fiber mesh cloth or carbon fiber mesh cloth.
[0028] The technical effects of the present invention are:
[0029] Most of the winding machines in the prior art rotate the mold, while the present invention rotates the material table, the slide rail, the winding frame, etc., while the mold and the central axis do not rotate. Therefore, the mold can be lifted out during demoulding. However, the existing mold can only be set as a fixed part because it rotates, and it cannot be lifted out. Only the finished glass fiber reinforced plastic cylinder can be lifted. Moreover, the finished glass fiber reinforced plastic cylinder is manufactured in sections, and then hoisted and assembled. However, the present invention has a movable mold. After the lower winding is completed, the mold moves upward, and the glass fiber reinforced plastic cylinder can be continuously manufactured. Therefore, the present invention can perform processing and installation operations inside the chimney.
[0030] The glass fiber composite material winding machine of the present invention can continuously wind without joints or leaks and has higher strength. Since the glass fiber composite material winding machine of the present invention can continuously wind, no steel hoop is required to strengthen the connection.
[0031] Since the fiberglass composite material winding machine of the present invention is constructed directly inside the chimney, there is no need to build a temporary factory building; at the same time, since the construction of the present invention is carried out directly inside the chimney (rather than first preparing the FRP cylinder and then hoisting it into the chimney), the FRP cylinder is not stored in the open air and the quality is more reliable. At the same time, there is no need to install a large-scale hoisting equipment for hoisting multiple FRP cylinders on the top of the chimney. Only hoisting equipment for hoisting the winding machine is required, and the entire construction process is not affected by bad weather. And since the construction is carried out inside the chimney, the FRP cylinder is directly manufactured inside the chimney without external hoisting, which can greatly reduce the process of secondary handling, and the cycle of the installation and disassembly process of the hoisting equipment is greatly shortened. The prior art requires about 50 workers to cooperate with a single work surface in the entire process from entering the site to the final completion, while the present invention can save about 50% of labor costs and about 30% of construction time.

DETAILED DESCRIPTION
[0042] Example 1
[0043] The glass fiber composite material winding machine 15 of the present invention is introduced in detail in conjunction with the accompanying drawings. The glass fiber composite material winding machine 15 of this embodiment includes a central axis 1, a material table 2, a sliding track 3, a wire winding frame 4, a support wheel 5, a slewing support bearing 6, a driving device 7, a support frame 81, a mold 8 and a support connecting ring 9.
[0044] like Figure 1 As shown, the material table 2 is a horizontal plate-like structure, which is used to carry the raw materials required for the production of glass fiber reinforced plastic cylinders. The central axis 1 is vertically arranged, and a lifting hole is opened at the top of the central axis 1. The central axis 1 passes through the material table 2. The slewing support bearing 6 is arranged below the material table 2, and the material table 2 is connected to the outer ring of the slewing support bearing 6. The lower part of the central axis 1 passes through the center hole of the slewing support bearing 6 and is connected to the inner ring of the slewing support bearing 6. The support frame 81 is connected to the bottom end of the central axis 1. The driving device 7 includes a driving motor and a reducer. The driving motor is connected to the reducer. The reducer meshes with the tooth portion of the outer ring of the slewing support bearing 6 through the output gear, and drives the rotation of the outer ring of the slewing support bearing 6.
[0045] The mold 8 is a vertical cylindrical structure with an open side wall. The top of the mold 8 is connected to the support frame 81, and the bottom is connected to the support connecting ring 9. The support connecting ring 9 is a ring structure and is used to support the mold 8. Figure 1 As shown, the outer diameter of the supporting connection ring 9 is equal to the outer diameter of the mold 8. The top of the slide track 3 is connected to the edge of the material table 2, and the bottom is rotatably connected to the outer wall of the bottom end of the mold 8 through the support wheel 5. The wire winding rack 4 is arranged on the slide track 3. The wire winding rack 4 is used to wind the material on the material table 2 on the mold 8. The wire winding rack 4 can slide up and down on the slide track 3; the driving motor provides power to drive the material table 2, the slide track 3 and the wire winding rack 4 to rotate around the central axis 1.
[0046] The wire winding frame is a common component in this type of equipment, such as Figure 7-Figure 9 As shown, the wire winding frame used in this embodiment includes a porous limiting plate 41, an arc frame 42 and a steel bracket 43. Two rows of through holes are longitudinally opened on the porous limiting plate. One end of the porous limiting plate is slidably connected to the slide track 3 through a pulley, and the other end is connected to the arc frame 42 through the steel bracket 43. The arc frame is used to pass the material and wind the material onto the mold 8. The material passes through the porous limiting plate and the arc frame, and then the material is wound onto the mold. Of course, different wire winding frames can also be used in different embodiments, as long as the material can be evenly wound onto the mold.
[0047] Since the driving motor of this embodiment is arranged horizontally, the reducer selected is a right-angle reversing reducer (which is an existing conventional device and can be directly purchased from the market), which reduces the speed of the horizontal rotation and changes the direction to vertical rotation.
[0048] Since the slide track 3 is vertically arranged and the material table 2 is horizontally arranged, the material needs to be transformed from horizontal to vertical form and wound through the wire winding frame 4. Therefore, a guide groove is arranged at the connection between the material table 2 and the slide track 3, and the guide groove guides the material on the material table 2 to the wire winding frame 4 of the slide track 3 in the form of a 90° bend angle.
[0049] The driving motor used in this embodiment is a commercially available driving motor of model: YX3-90L-4.

The reinforcing layer 12 is a sealing layer of carbon fiber mesh cloth to ensure that the connection between the bottom of the FRP cylinder and the supporting platform ring beam 10 is sealed to form a closed whole.
[0057] 6) If Figure 4 As shown, demoulding is performed by hoisting equipment on the top of the chimney (the various components of the glass fiber composite material winding machine are hoisted one by one. Since a vertical opening is provided on the mold, the diameter can be reduced, and demoulding is performed by reducing the diameter of the mold when the mold is hoisted), and the glass fiber composite material winding machine 15 (including the mold) is gradually lifted to the upper part of the first section of the glass fiber reinforced plastic cylinder 13 obtained in step 5), and the supporting connecting ring 9 is installed above the inner wall of the first section of the glass fiber reinforced plastic cylinder 13.
