Description

Technical Field

[0001] This invention relates to the field of parabolic trough solar collector installation technology, specifically a method for controlling the installation accuracy of foundation anchor bolts for parabolic trough solar collectors. Background Technology

[0002] In the concentrated solar power (CSP) industry, parabolic trough collectors offer advantages such as high collection efficiency and small footprint. The typical structure of a parabolic trough collector involves supporting torque tubes with a support frame, mounting a frame on the torque tubes, and then installing reflectors on the frame. Solar energy is collected through the reflectors and used to heat the heat transfer medium. However, during actual installation, inaccurate installation positions often result in tilted, misaligned, or inconsistently positioned foundation anchor bolts, creating safety hazards during operation.

[0003] In the prior art, a device and method for precise positioning of large anchor bolt groups, disclosed in CN113818703A, includes anchor bolts, a support ring plate, and a positioning ring plate with multiple anchor bolt pre-drilled holes. A first support leg is provided between the support ring plate and the ground. The positioning ring plate is located above the support ring plate, and a second support leg is provided between the positioning ring plate and the support ring plate. The anchor bolts pass through the anchor bolt pre-drilled holes in the positioning ring plate, and the anchor bolt bases are fixed to the support ring plate. This device and method for precise positioning of large anchor bolt groups can effectively solve the problems of installation, fixing, and precision control of large-sized anchor bolts in furnaces, blast furnaces, hot blast stoves, etc. It has low manufacturing cost, strong operability, and can effectively control the installation accuracy, providing a favorable guarantee for the smooth progress of subsequent installation work.

[0004] However, its use still has some obvious defects: 1. In the above positioning method, the anchor bolts are placed in the anchor bolt pre-drilled holes of the positioning ring plate. However, it cannot be guaranteed that the anchor bolts are centered in the pre-drilled holes. If the anchor bolts are close to one side of the inner wall or the gap is too small, it will be difficult to fill the gap during subsequent grouting, resulting in holes in the concrete and reducing the stability of the installation; 2. The above process requires continuous adjustment according to the elevation of the anchor bolts during installation. The adjustment process is complicated and requires the use of mechanical equipment, which is quite cumbersome; 3. The above method cannot guarantee the verticality of the anchor bolts after installation. If the anchor bolts are tilted, the overall stability will be greatly reduced. Moreover, the tilt of the anchor bolts will cause the vibration of the structure to be aggravated, which may cause structural fatigue and thus affect the service life of the structure; 4. The above method first fixes the support ring plate and the positioning ring plate, and then installs the anchor bolts. Since the support ring plate and the positioning ring are already positioned in the installation groove, the subsequent installation position of the anchor bolts is very limited. The operating space is small and difficult to handle, which affects the construction efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a method for controlling the installation accuracy of anchor bolts on the foundation of a trough solar collector, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A method for controlling the installation accuracy of anchor bolts for a trough-type solar collector foundation includes the following steps:

[0008] Step 1: Drill holes in the positioning mold plate, and set positioning holes and weight reduction holes at intervals in sequence;

[0009] Step 2: Clamp and position multiple anchor bolts according to the positions of the positioning holes. Screw the lower nut and retaining ring into the vertical section of the anchor bolt from bottom to top, and paint the center point of the top of the anchor bolt.

[0010] Step 3: Hoist the positioning mold plate, align all the positioning holes with the corresponding anchor bolts, and then lower the positioning mold plate so that the anchor bolts pass through the positioning holes;

[0011] Step 4: Adjust the horizontal position of the anchor bolts, and ensure that the distance from the anchor bolts to each side of the inner wall of the positioning hole is not less than 15mm.

[0012] Step 5: Adjust the height of the anchor bolts;

[0013] Step Six: Adjust the verticality of the anchor bolts;

[0014] Step 7: Use a level, theodolite and verticality measuring instrument to check the position of the above anchor bolts. After confirming that there is no error, push the retaining ring upward until there is no gap between the retaining ring and the bottom of the positioning mold plate. Then rotate it upward and tighten the lower nut until there is no gap between the lower nut and the retaining ring.

[0015] Step 8: Pour a concrete ring into the positioning hole;

[0016] Step 9: Repeat steps 4 to 8 above until the positioning and installation between all anchor bolts and positioning mold plates are completed;

[0017] Step 10: Set up multiple outer limiting plates on the outside of the positioning mold plate, and dig an installation groove according to the outer perimeter spacing of the outer limiting plates. Hoist the outer limiting plates, positioning mold plate and anchor bolts as a whole into the installation groove.

[0018] Step 11: Pour concrete into the installation groove until the positioning mold and anchor bolts solidify into a whole.

[0019] Preferably, step two further includes:

[0020] Before clamping the anchor bolts, clean the rust and oil off the anchor bolts, apply grease to the threaded part of the anchor bolts, and the inner ring of the retaining ring is provided with an elastic sealing ring.

[0021] Preferably, step four specifically includes:

[0022] The positioning mold plate is fixedly equipped with an inner ring slide rail and an outer ring slide rail. An inner slider is movably mounted on the inner ring slide rail, and an outer slider is movably mounted on the outer ring slide rail. A first semi-circular ring plate is fixedly mounted on the inner slider, and a second semi-circular ring plate is fixedly mounted on the outer slider. A vertical rod is fixedly mounted on the first semi-circular ring plate, and a rotating shaft is fixedly mounted through the vertical rod. A straight rod is hinged to the rotating shaft, and a transparent central disk is located at the center of the straight rod. A locking block is fixedly mounted on the second semi-circular ring plate. The first and second semi-circular ring plates are slid to the outside of either positioning hole, and the straight rod is rotated and closed until it touches the locking block. The moving anchor bolts are adjusted so that the center point of the anchor bolt's color is aligned with the transparent central disk.

[0023] Preferably, step five specifically includes:

[0024] Move the anchor bolts so that the top of the anchor bolts is attached to the bottom of the transparent central disc.

[0025] Preferably, step six specifically includes:

[0026] A horizontal plate is fixedly installed on the side of the second semi-circular plate. A first cylinder is fixedly installed at the bottom of the horizontal plate. An installation rod is fixedly installed on the piston shaft of the first cylinder. A camera is fixedly installed on the side of the installation rod facing the positioning hole. A second cylinder is fixedly installed at the bottom of the installation rod. An installation block is fixedly installed on the piston shaft of the second cylinder. A pressure sensor is installed in a groove inside the installation block. A pressure rod is connected to the groove inside the installation block by a spring. A hinge shaft is hinged to the end of the pressure rod away from the installation block. A disc is fixedly installed on the hinge shaft. When the second cylinder is activated, the disc presses against the side of the anchor bolt. Then, the first cylinder is activated, causing the disc to move downward along the side of the anchor bolt. If the pressure detected by the pressure sensor changes during this process, it indicates that the anchor bolt is in an inclined state, and the verticality of the anchor bolt is adjusted.

[0027] Preferably, after step eight, the method further includes:

[0028] Take the top nut and screw it into the anchor bolt until there is no gap between the top nut and the top of the positioning mold plate.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. When installing anchor bolts, the present invention can adjust the horizontal and lateral position of the anchor bolts, and the distance from the anchor bolts to each side of the inner wall of the positioning hole is not less than 15mm, which facilitates the full pouring of concrete, avoids the formation of holes, and makes the connection more secure.

[0031] 2. This invention allows for easy adjustment of the height of the anchor bolts. By moving the anchor bolts, the top of the anchor bolts can be placed against the bottom of the transparent central disc, which is intuitive, convenient, and more efficient.

[0032] 3. This invention can detect the verticality of anchor bolts, is simple to operate, and allows for real-time adjustment of the tilt during the detection process, resulting in more stable installation of the structure.

[0033] 4. In this invention, the anchor bolts and positioning mold are first fixed in an open construction site, and then the anchor bolts and positioning mold are hoisted and placed in the installation groove as a whole. Therefore, there is more operating space for positioning anchor bolts in different positions, which is easier to handle. In addition, this invention first positions the upper part of the anchor bolt and then pours concrete at the bottom. With the upper part fixed, the positioning at the bottom is more stable and reliable.

[0034] This invention provides a method for controlling the installation accuracy of anchor bolts for trough solar collector foundations. It can stably install the anchor bolts according to predetermined standards in terms of horizontal position, height, and verticality. The operation sequence is reasonable, the installation is simple, and the efficiency is higher. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1 to 6 The present invention provides a technical solution:

[0044] Example 1:

[0045] A method for controlling the installation accuracy of anchor bolts for a trough-type solar collector foundation includes the following steps:

[0046] Step 1: Drill holes in the positioning mold plate 1, and set positioning holes 101 and weight reduction holes 102 at intervals. Positioning holes 101 are used to install anchor bolts 12. The setting of weight reduction holes 102 can not only reduce the weight of positioning mold plate 1, but also reduce the amount of material used in positioning mold plate 1, thereby saving costs.

[0047] Step 2: Clamp and position multiple anchor bolts 12 according to the position of the positioning hole 101. This operation can be performed in an open space, not limited to the installation site of the trough collector, solving the problem of limited space and inconvenient operation. Screw the lower nut 14 and the retaining ring 13 into the vertical section of the anchor bolt 12 from bottom to top. The lower nut 14 is threaded on the vertical section of the anchor bolt 12 and can rotate and move up or down. The purpose of the retaining ring 13 is mainly to cover the bottom of the positioning hole 101 to facilitate the subsequent concrete pouring operation. The center point of the top of the anchor bolt 12 is painted. The painting range is based on the predetermined acceptable lateral mis-touch range, thereby determining the acceptable installation position of the anchor bolt 12.

[0048] Step 3: Hoist the positioning mold plate 1, align the multiple positioning holes 101 with the corresponding anchor bolts 12, and then lower the positioning mold plate 1 so that the anchor bolts 12 pass through the positioning holes 101. During this process, the position of the anchor bolts 12 can be adjusted so that the positions of the anchor bolts 12 and the positioning holes 101 correspond.

[0049] Step 4: Adjust the horizontal position of the anchor bolt 12, and ensure that the distance from the anchor bolt to each side of the inner wall of the positioning hole 101 is not less than 15mm, so as to facilitate full concrete pouring, avoid the formation of holes, and make the connection more secure.

[0050] Step 5: Adjust the height of anchor bolt 12 so that the top of anchor bolt 12 remains flush.

[0051] Step 6: Adjust the verticality of the anchor bolts 12 to prevent them from tilting and affecting the stability of the structure;

[0052] Step 7: Use a level, theodolite and verticality measuring instrument to check the position of the anchor bolts 12. After confirming that there is no error, push the retaining ring 13 upward until there is no gap between the retaining ring 13 and the bottom of the positioning mold plate 1. The retaining ring 13 can cover the bottom of the positioning hole 101, which facilitates the subsequent concrete pouring operation. Then rotate the lower nut 14 upward and tighten it until there is no gap between the lower nut 14 and the retaining ring 13.

[0053] Step 8: Pour a concrete ring 26 into the positioning hole 101 to fix the anchor bolt 12 and the positioning mold plate 1 together, thereby achieving upper positioning of the anchor bolt 12;

[0054] Step 9: Repeat steps 4 to 8 above until all anchor bolts 12 and positioning mold plate 1 are positioned and installed. This operation can be performed in an open space and is not limited to the installation site of the trough collector, which solves the problem of limited space and inconvenient operation.

[0055] Step 10: Install multiple outer limiting plates 28 on the outside of the positioning mold plate 1, and dig installation grooves 29 according to the outer perimeter spacing of the outer limiting plates 28. Hoist the outer limiting plates 28, positioning mold plate 1 and anchor bolts 12 as a whole into the installation grooves 29.

[0056] Step 11: Pour concrete into the installation slot 29 until the positioning mold plate 1 and the anchor bolts 12 solidify into a whole, ensuring accurate positioning and higher efficiency.

[0057] Example 2:

[0058] A method for controlling the installation accuracy of anchor bolts for a trough-type solar collector foundation includes the following steps:

[0059] Step 1: Drill holes in the positioning mold plate 1, and set positioning holes 101 and weight reduction holes 102 at intervals. Positioning holes 101 are used to install anchor bolts 12. The setting of weight reduction holes 102 can not only reduce the weight of positioning mold plate 1, but also reduce the amount of material used in positioning mold plate 1, thereby saving costs.

[0060] Step Two: Before clamping the anchor bolts 12, clean off any rust and oil from them. Apply grease to the threads of the anchor bolts. Applying grease reduces friction on the threads, making tightening easier, reducing wear, and extending their service life. Clamp and position multiple anchor bolts 12 according to the positioning holes 101. This operation can be performed in an open area, not limited to the installation location of the trough solar collector, solving the problem of limited space and inconvenient operation. Screw the anchor bolts 12 vertically from bottom to top. The lower nut 14 and the retaining ring 13 are threaded onto the vertical section of the anchor bolt 12 and can rotate and move up or down. The purpose of the retaining ring 13 is to cover the bottom of the positioning hole 101 to facilitate subsequent concrete pouring. An elastic sealing ring 131 is provided in the inner ring of the retaining ring 13. The elastic sealing ring 131 improves the sealing effect and thus prevents concrete from being lost during the pouring process. The center point of the top of the anchor bolt 12 is painted with color. The coloring range is based on the predetermined acceptable lateral mis-touch range to determine the acceptable installation position of the anchor bolt 12.

[0061] Step 3: Hoist the positioning mold plate 1, align the multiple positioning holes 101 with the corresponding anchor bolts 12, and then lower the positioning mold plate 1 so that the anchor bolts 12 pass through the positioning holes 101. During this process, the position of the anchor bolts 12 can be adjusted so that the positions of the anchor bolts 12 and the positioning holes 101 correspond.

[0062] Step 4: Adjust the horizontal position of the anchor bolt 12, and ensure that the distance from the anchor bolt to each side of the inner wall of the positioning hole 101 is not less than 15mm, so as to facilitate full concrete pouring, avoid the formation of holes, and make the connection more secure.

[0063] Step 5: Adjust the height of anchor bolt 12. After adjustment, the top of anchor bolt 12 can be kept flush. Specifically, move anchor bolt 12 so that the top of anchor bolt 12 is attached to the bottom of transparent central disc 10. The movement operation is simple and intuitive.

[0064] Step 6: Adjust the verticality of the anchor bolts 12 to prevent them from tilting and affecting the stability of the structure;

[0065] Step 7: Use a level, theodolite and verticality measuring instrument to check the position of the anchor bolts 12. After confirming that there is no error, push the retaining ring 13 upward until there is no gap between the retaining ring 13 and the bottom of the positioning mold plate 1. The retaining ring 13 can cover the bottom of the positioning hole 101, which facilitates the subsequent concrete pouring operation. Then rotate the lower nut 14 upward and tighten it until there is no gap between the lower nut 14 and the retaining ring 13.

[0066] Step 8: Pour a concrete ring 26 into the positioning hole 101 to fix the anchor bolt 12 and the positioning mold plate 1 together, thereby positioning the upper part of the anchor bolt 12. Then, take the upper nut 27 and screw the upper nut 27 into the anchor bolt 12 until there is no gap between the upper nut 27 and the top of the positioning mold plate 1. Thus, with the cooperation of the upper nut 27 and the lower nut 14, the height position of the anchor bolt 12 is further defined.

[0067] Step 9: Repeat steps 4 to 8 above until all anchor bolts 12 and positioning mold plate 1 are positioned and installed. This operation can be performed in an open space and is not limited to the installation site of the trough collector, which solves the problem of limited space and inconvenient operation.

[0068] Step 10: Install multiple outer limiting plates 28 on the outside of the positioning mold plate 1, and dig installation grooves 29 according to the outer perimeter spacing of the outer limiting plates 28. Hoist the outer limiting plates 28, positioning mold plate 1 and anchor bolts 12 as a whole into the installation grooves 29.

[0069] Step 11: Pour concrete into the installation slot 29 until the positioning mold plate 1 and the anchor bolts 12 solidify into a whole, ensuring accurate positioning and higher efficiency.

[0070] Example 3:

[0071] This embodiment, based on the above embodiment one or embodiment two, further discloses and limits step four: Step four specifically includes:

[0072] An inner ring slide rail 2 and an outer ring slide rail 3 are fixedly mounted on the positioning mold plate 1. An inner slider 4 is movably mounted on the inner ring slide rail 2, and an outer slider 5 is movably mounted on the outer ring slide rail 3. Thus, the inner slider 4 can slide along the inner ring slide rail 2, and the outer slider 5 can slide along the outer ring slide rail 3. A first semi-circular ring plate 601 is fixedly mounted on the inner slider 4, and a second semi-circular ring plate 602 is fixedly mounted on the outer slider 5. A vertical rod 7 is fixedly mounted on the first semi-circular ring plate 601, and a rotating shaft 8 is fixedly and through the vertical rod 7. A straight rod 9 is hinged to the rotating shaft 8 and can rotate around the rotating shaft 8. A transparent center is provided at the center of the straight rod 9. The center disc 10 and the second semicircular ring plate 602 are fixedly provided with a locking block 11. Inner marking points and outer marking points are respectively set on the inner side of the inner ring slide rail 2 and the outer side of the outer ring slide rail 3. When the inner slider 4 moves to the inner marking point and the outer slider 5 moves to the outer marking point, the end of the straight rod 9 is rotated to contact the locking block 11. At this time, the straight rod 9 is set along the diameter direction of the positioning hole 101, and the transparent center disc 10 is located at the center position of the positioning hole 101. Adjust the moving anchor bolt 12 so that the center point of the anchor bolt 12 is aligned with the transparent center disc 10, thereby ensuring that the anchor bolt 12 is installed at the center position of the positioning hole 101.

[0073] Example 4:

[0074] This embodiment, based on the above embodiment one or embodiment two, further discloses and limits step six: Step six specifically includes:

[0075] A horizontal plate 15 is fixedly installed on the side of the second semicircular ring plate 602, and a first cylinder 16 is fixedly installed at its bottom. A mounting rod 17 is fixedly installed on the piston shaft of the first cylinder 16. A camera 18 is fixedly installed on the side of the mounting rod 17 facing the positioning hole 101. The camera 18 can record the verticality detection process in real time, solving the problem that the installer cannot directly observe the position. A second cylinder 19 is fixedly installed at the bottom of the mounting rod 17, and a mounting block 20 is fixedly installed on the piston shaft of the second cylinder 19. A pressure sensor 21 is installed in the groove inside the mounting block 20. The pressure sensor 21 can monitor the pressure in real time and display it on an external display screen. The internal groove of the mounting block 20 is equipped with a spring. A spring 22 is connected to a pressure rod 23. The end of the pressure rod 23 away from the mounting block 20 is hinged to a hinge shaft 24. A disc 25 is fixedly mounted on the hinge shaft 24. When the second cylinder 19 is activated, the disc 25 presses against the side of the anchor bolt 12. At this time, the pressure rod 23 will squeeze the pressure sensor 21, so the pressure sensor 21 can monitor the pressure data in real time. Then, the first cylinder 16 is activated, so the disc 25 moves downward along the side of the anchor bolt 12. If the pressure detected by the pressure sensor 21 changes during this process, it indicates that the anchor bolt 12 is in an inclined state. The verticality of the anchor bolt 12 is adjusted. After adjustment, a verification test can be performed to ensure the verticality of the anchor bolt 12 installation. The operation is simple.
