Description

Technical Field

[0001] This invention relates to the field of wind turbine tower construction technology, specifically to a construction equipment and method for reinforced concrete wind turbine towers. Background Technology

[0002] With the rapid development of the new energy industry, the construction demand for wind turbine towers, as the core basic components of wind power generation projects, continues to rise. In the construction process of reinforced concrete wind turbine towers, the laser verticality measuring instrument support frame is an important supporting component for the inspection operation. Its performance directly affects the verticality accuracy of the tower construction. Therefore, a highly adaptable laser verticality measuring instrument support frame is needed to carry out on-site inspection and support operations.

[0003] However, existing construction equipment is difficult to keep the support device in a stowed position during use. It is easily shaken by external forces or affected by its own weight and will unfold on its own. This not only occupies extra space, but also causes structural damage during transportation and storage. Summary of the Invention

[0004] The purpose of this invention is to provide a construction equipment and method for reinforced concrete wind turbine towers. By setting up a storage section, the invention solves the problem that existing construction equipment is difficult to maintain the stored posture of the support device during use, and is easily shaken by external forces or affected by its own weight, causing it to unfold on its own. This not only occupies extra space, but also leads to structural damage during transportation and storage.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a construction device and method for reinforced concrete wind turbine towers, comprising a support rod and a laser guide rail plumb bob mounted on the top of the support rod, and further comprising: a storage part mounted on the support rod; a locking part mounted on the support rod; a support part mounted on the support rod; the storage part includes a locking assembly mounted on the support rod; and a pressing assembly mounted on the support rod; the locking assembly includes a ring slidably connected to the outer wall of the support rod, with two fixing blocks fixedly connected to the top of the ring, and a fixing frame fixedly connected to the outer wall of the support rod, the fixing frame having two limiting grooves, each of which has a slider slidably connected, and each of the sliders having a locking block fixedly connected to its bottom, the locking blocks respectively fitting with the two fixing blocks, and each of the limiting grooves having an elastic element; the fixing frame is located above the ring.

[0006] Furthermore, the locking part includes a locking component disposed on the support rod; and an elastic component disposed on the support rod.

[0007] Furthermore, the support portion includes a support assembly mounted on a ring and a hinge assembly mounted on a support rod.

[0008] Furthermore, the extrusion assembly includes a second ring slidably connected to the outer wall of the support rod. A first spring is sleeved on the outer wall of the support rod. The top of the first spring is fixedly connected to the second ring, and the bottom of the first spring is fixedly connected to the fixing frame. Two extrusion rods are fixedly connected to the bottom of the second ring. The two extrusion rods are respectively adapted to two sliders. The two extrusion rods are mirror images of each other.

[0009] Furthermore, the locking assembly includes a cylindrical groove formed on the second ring, a fixing rod disposed in the cylindrical groove, the front side of the fixing rod extending to the outside of the second ring, the fixing rod being slidably connected to the second ring, and a locking groove formed on the outer wall of the support rod; the fixing rod is adapted to the locking groove.

[0010] Furthermore, the elastic component includes a circular limiting plate fixedly connected to the outer wall of the fixed rod, the circular limiting plate being slidably connected to the inner wall of the cylindrical groove, and a second spring being sleeved on the outer wall of the fixed rod, the front side of the second spring being fixedly connected to the second ring, and the rear side of the second spring being fixedly connected to the circular limiting plate; both the circular limiting plate and the second spring are located inside the cylindrical groove.

[0011] Furthermore, the support assembly includes several hinge blocks one fixedly connected to the outer wall of the ring one, and each of the several hinge blocks one is hinged with a support leg; there are three hinge blocks one arranged in a circumferential array.

[0012] Furthermore, the hinge assembly includes a circular plate fixedly connected to the bottom of the support rod, a plurality of hinge blocks 2 are fixedly connected to the outer wall of the circular plate, and hinge rods are hinged to each of the hinge blocks 2. A plurality of hinge blocks 3 are fixedly connected to the outer wall of each of the support legs, and the plurality of hinge blocks 3 are respectively hinged to the plurality of hinge rods. There are three hinge blocks 2, arranged in a circumferential array.

[0013] Furthermore, the laser guide rail plumb line in this device is model JC300B. Based on the principles of optical collimation and gravity reference, the laser guide rail plumb line emits a coaxial visible laser beam through a built-in laser. An automatic compensation system ensures that the laser beam is precisely aligned with the gravity plumb line. During tower construction, a station is set up at the bottom and a vertical laser reference line is projected upwards. In conjunction with a target to receive the light spot, the deviation between the tower at different heights and the reference plumb line is compared in real time, thereby realizing the dynamic detection and correction of the overall verticality of the reinforced concrete wind turbine tower.

[0014] The present invention has the following beneficial effects: (1) The present invention is provided with a storage part. Pressing down on the second ring can compress the first spring, which drives the compression rod to push the slider away from each other along the limiting groove and compress the spring damping rod to store energy, so that the locking block is separated from the fixed block and the ring is released from the fixation. Pulling the ring one upward, the fixed block compresses the locking block and the slider away through the inclined surface and compresses the spring damping rod. After the two are aligned, the spring damping rod releases the elastic force to drive the locking block to reset and lock the ring one, thereby maintaining the retracted state of the support leg. It can stably maintain the retracted posture of the support leg and effectively solve the problem that the existing equipment support device is easily shaken by external force after being retracted and self-unfolded due to its own weight. It improves the convenience and safety of equipment transportation and storage. (2) The present invention is equipped with a locking part. When in use, the fixed rod is pulled to drive the circular limiting plate to move and squeeze the spring two, so that the fixed rod is disengaged from the locking groove and the limiting and fixing of the ring two is released. After being stored in place, the fixed rod and the locking groove re-form a locking limit, locking the position of the ring two, preventing the ring two from moving down by itself due to external influence, preventing the squeezing rod from accidentally pressing the slider, thereby ensuring the stability of the locked state of the ring one, effectively preventing the parts from malfunctioning due to external force or vibration, preventing the internal linkage structure from being accidentally unlocked, and the overall locking protection is strong. It can maintain the locked state after the device is stored for a long time, further improving the overall stability and safety of the equipment. (3) The present invention is provided with a support part. Pressing the ring one moves down along the support rod, and the three support legs move through the hinge block one. Relying on the hinge linkage relationship between the support legs, the hinge rod and the circular plate, the three support legs open outward synchronously, and the support rod is stably supported on the ground, so as to realize the placement and positioning of the laser guide rail plumb line, quickly complete the erection and support of the equipment, effectively ensure the stability of the laser guide rail plumb line after placement, and avoid deviation during operation.

Detailed Implementation

[0019] 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.

[0020] Please see Figures 1-7 As shown, the present invention is a construction equipment and method for reinforced concrete wind turbine towers, including a support rod 111 and a laser guide rail plumb bob 112 installed on the top of the support rod 111, and further including: a storage part 2, which is installed on the support rod 111; a locking part 3, which is disposed on the support rod 111; and a support part 4, which is installed on the support rod 111.

[0021] The storage section 2 includes a locking assembly 21, which is mounted on the support rod 111; and a pressing assembly 22, which is also mounted on the support rod 111. The locking assembly 21 includes a ring 211 slidably connected to the outer wall of the support rod 111. Two fixing blocks 212 are fixedly connected to the top of the ring 211. A fixing frame 213 is fixedly connected to the outer wall of the support rod 111. Two limiting grooves 214 are provided on the fixing frame 213. A slider 215 is slidably connected in each of the two limiting grooves 214. A locking block 216 is fixedly connected to the bottom of each of the two sliders 215. The two locking blocks 216 are respectively adapted to the two fixing blocks 212. An elastic element is provided in each of the two limiting grooves 214. The fixing frame 213 is positioned... Above the first ring 211, the extrusion assembly 22 includes a second ring 221 slidably connected to the outer wall of the support rod 111. A first spring 222 is sleeved on the outer wall of the support rod 111. The top of the first spring 222 is fixedly connected to the second ring 221, and the bottom of the first spring 222 is fixedly connected to the fixing frame 213. Two extrusion rods 223 are fixedly connected to the bottom of the second ring 221. The two extrusion rods 223 are respectively adapted to two sliders 215. The two extrusion rods 223 are mirror images of each other. By setting the storage part 2, the storage posture of the support leg 412 can be stably maintained, effectively solving the problem that the existing equipment support device is easily shaken by external force after storage and self-expanding due to its own weight, thus improving the convenience and safety of equipment transportation and storage.

[0022] The locking part 3 includes a locking assembly 31, which is mounted on the support rod 111; and an elastic assembly 32, which is also mounted on the support rod 111. The locking assembly 31 includes a cylindrical groove 311 formed on the second annulus 221, and a fixing rod 312 is disposed within the cylindrical groove 311. The front side of the fixing rod 312 extends to the outside of the second annulus 221, and the fixing rod 312 is slidably connected to the second annulus 221. A locking groove 313 is formed on the outer wall of the support rod 111. The fixing rod 312 is adapted to the locking groove 313. The elastic assembly 32 includes a circular limiting plate 32 fixedly connected to the outer wall of the fixing rod 312. 1. The circular limiting plate 321 is slidably connected to the inner wall of the cylindrical groove 311. The outer wall of the fixing rod 312 is fitted with a spring 322. The front side of the spring 322 is fixedly connected to the ring 221, and the rear side of the spring 322 is fixedly connected to the circular limiting plate 321. The circular limiting plate 321 and the spring 322 are both located in the cylindrical groove 311. By setting the locking part 3, the component is effectively prevented from malfunctioning due to external force or vibration, and the internal linkage structure is prevented from being accidentally unlocked. The overall locking protection is strong and can maintain the locked state after the device is stored for a long time, further improving the overall stability and safety of the equipment.

[0023] The support part 4 includes a support assembly 41, which is mounted on a ring 211; and a hinge assembly 42, which is mounted on a support rod 111. The support assembly 41 includes a plurality of hinge blocks 411 fixedly connected to the outer wall of the ring 211, and each hinge block 411 is hingedly provided with a support leg 412. There are three hinge blocks 411 arranged in a circumferential array. The hinge assembly 42 includes a circular plate 421 fixedly connected to the bottom of the support rod 111. The wall is fixedly connected with several hinge blocks 422, and each hinge block 422 is hinged with a hinge rod 423. The outer walls of several support legs 412 are fixedly connected with hinge blocks 424, and each hinge block 424 is hinged to a hinge rod 423. There are three hinge blocks 422 arranged in a circular array. By setting the support part 4, the equipment can be quickly erected and supported, effectively ensuring the stability of the laser guide rail plumb line 112 after placement and avoiding deviation during operation.

[0024] When in use, pull the fixing rod 312, the fixing rod 312 drives the circular limiting plate 321 to move, the circular limiting plate 321 squeezes the spring 322, causing the circular limiting plate 321 to deform and generate elastic force, thereby causing the fixing rod 312 to move out of the locking groove 313 and release the fixing of the ring 221. Then, the second ring 221 is pressed down on the support rod 111 and moves downward. The second ring 221 compresses the first spring 222, causing the first spring 222 to deform and generate elastic force. At this time, the second ring 221 drives the two compression rods 223 to move downward and compress the two sliders 215 respectively, causing the two sliders 215 to slide in the corresponding limiting grooves 214 and move away from each other. The two sliders 215 compress the two spring damping rods 217 respectively, causing the two spring damping rods 217 to deform and generate elastic force. During this process, the two sliders 215 drive the two locking blocks 216 to move away from each other and away from the two fixing blocks 212 respectively, thereby releasing the fixation of the two fixing blocks 212 and thus releasing the fixation of the first ring 211. Pressing the ring 211 causes it to move downward on the support rod 111. The ring 211 pushes the three support legs 412 to move through the three hinge blocks 411. Since the three support legs 412 are hinged to the three hinge rods 423 through the three hinge blocks 424 respectively, and the three hinge rods 423 are hinged to the circular plate 421 through the corresponding hinge blocks 422 respectively, when the three support legs 412 move downward, under the action of the hinge rods 423, the three support legs 412 are pushed to move on the three hinge blocks 411 respectively and move away from each other, thereby unfolding the three support legs 412 and standing the support rod 111 on the ground, thus positioning the laser guide rail plumb bob 112. Subsequently, the laser guide rail plumb bob 112 is activated. The laser guide rail plumb bob 112 has a built-in laser that emits a coaxial visible laser beam. The automatic compensation system ensures that the laser beam is precisely aligned with the gravity plumb line. During tower construction, a station is set up at the bottom and a vertical laser reference line is projected upwards. In conjunction with the target receiving the light spot, the deviation between the tower at different heights and the reference plumb line is compared in real time, thereby realizing the dynamic detection and correction of the overall verticality of the reinforced concrete wind turbine tower. When the three support legs 412 need to be retracted, the ring 211 is pulled upwards. The ring 211 moves the two fixed blocks 212. The two fixed blocks 212 press against the two locking blocks 216 through the inclined surfaces, causing the two locking blocks 216 to move away from each other. The two locking blocks 216 then move the two sliders 215 away from each other and press against the two spring damping rods 217, causing them to generate elastic force. When the two fixed blocks 212 are aligned with the two locking blocks 216, the pressing force on the two spring damping rods 217 disappears, releasing the elastic force. The elastic force acts on the sliders 215, and the two sliders 215 drive the two locking blocks 216 to reset and form a locking structure with the two fixed blocks 212, fixing the position of the ring 211 and thus indirectly maintaining the state of the three support legs 412 when retracted. After storage, the ring 221 is fixed by the engagement of the fixing rod 312 and the locking groove 313, preventing the ring 221 from moving downward under the influence of external factors, thereby preventing the two pressing rods 223 from pressing the two sliders 215, and thus indirectly maintaining the stability of the ring 211 after it is fixed.

10. The construction equipment and method for reinforced concrete wind turbine towers according to claim 9, wherein the method of using the construction equipment for reinforced concrete wind turbine towers according to claim 9 is characterized in that, Includes the following steps: S1: In use, pull the fixing rod (312), which drives the circular limiting plate (321) to move. The circular limiting plate (321) compresses the second spring (322), causing the circular limiting plate (321) to deform and generate elastic force, thereby causing the fixing rod (312) to move out of the locking groove (313) and release the fixation of the second ring (221). Then press the second ring (221) to move downward on the support rod (111), and the second ring (221) presses against the first spring (222). When the compression is applied, spring one (222) deforms and generates elastic force. At this time, ring two (221) drives the two compression rods (223) to move downwards and compress the two sliders (215) respectively, causing the two sliders (215) to slide in the corresponding limiting grooves (214) and move away from each other. The two sliders (215) compress the two spring damping rods (217) respectively, causing the two spring damping rods (217) to deform and generate elastic force. During this process, the two sliders ( 215) respectively drive the two locking blocks (216) away from each other and away from the two fixed blocks (212), thereby releasing the fixation of the two fixed blocks (212) and releasing the fixation of the ring one (211); press the ring one (211) down on the support rod (111), the ring one (211) pushes the three support legs (412) to move through the three hinge blocks one (411), since the three support legs (412) are respectively connected to the three hinge rods (424) through the three hinge blocks three (424) and the three hinge rods (424). 23) The three hinge rods (423) are respectively hinged to the circular plate (421) through the corresponding hinge block two (422). So when the three support legs (412) move downward, under the action of the hinge of the three hinge rods (423), the three support legs (412) are pushed to move on the three hinge blocks one (411) respectively and move away from each other, thereby unfolding the three support legs (412) and standing the support rod (111) on the ground, thereby positioning the laser guide rail plumb bob (112); S2: Then the laser guide rail plumb line (112) is started. The laser guide rail plumb line (112) has a built-in laser that emits a coaxial visible laser beam. The automatic compensation system ensures that the laser beam is accurately aligned with the gravity plumb line. During tower construction, a station is set up at the bottom and a vertical laser reference line is projected upward. The target receives the light spot and compares the deviation of the tower at different heights from the reference plumb line in real time, thereby realizing the dynamic detection and correction of the overall verticality of the reinforced concrete wind turbine tower. S3: When the three support legs (412) need to be retracted, pull the first ring (211) upward. The first ring (211) drives the two fixed blocks (212) to move. The two fixed blocks (212) press the two locking blocks (216) through the inclined plane, causing the two locking blocks (216) to move away from each other. The two locking blocks (216) drive the two sliders (215) to move away from each other and press the two spring damping rods (217) to generate elastic force. When the two fixed blocks (212) are aligned with the two locking blocks (216), the pressing force on the two spring damping rods (217) disappears, releasing the elastic force. The elastic force acts on the sliders ( On 215), the two sliders (215) respectively drive the two locking blocks (216) to reset, and respectively form a locking structure with the two fixing blocks (212) to fix the position of the first ring (211), thereby indirectly maintaining the state of the three support legs (412) when they are retracted; after the storage is completed, under the action of the locking rod (312) and the locking groove (313) forming a locking, the second ring (221) is fixed, preventing the second ring (221) from moving downward under the action of external factors, thereby preventing the two squeezing rods (223) from squeezing the two sliders (215), thereby indirectly maintaining the stability of the first ring (211) after it is fixed.
