Description

Technical Field

[0001] The present invention relates to the technical field of concrete towers, in particular to a safety belt fixing device inside a concrete tower. Background Art

[0002] With the development of wind turbine technology, wind turbine power is getting bigger and bigger, and blades are getting longer and longer. There are more and more requirements for high-tower wind turbines. The height of wind turbine towers has rapidly developed from 100m to 140m and above. The load of wind turbine towers is also getting bigger and bigger. Traditional steel towers can no longer meet the structural stress requirements. Concrete tower technology will become the mainstream choice in the market.

[0003] At present, prefabricated hybrid towers for wind power are generally composed of traditional steel cylinder sections and concrete pipe segments, which are connected by a conversion device in the middle. Concrete and steel cylinders complement each other by taking advantage of their respective advantages to ensure the safety of the tower and improve the economy of the tower, providing a new option for solving the power generation problem in low wind speed areas. Most prefabricated hybrid towers adopt full-straight, segmented and segmented splicing types. Segmented splicing means that the segments of the hybrid tower are made up of multiple pieces and are fixed by grouting or bolting.

[0004] When working inside a concrete tower, safety measures such as anti-fall ropes need to be equipped. An anti-fall rope is installed inside the existing concrete tower, and the anti-fall rope is installed at the ladder position inside the concrete tower. The safety hanging point and the anti-fall rope are installed before the concrete tower is lifted. However, the ladder is usually not designed to withstand the impact of a fall. Its structural strength and stability cannot meet the force requirements of the safety belt rope. It only relies on the ladder as a fixing point for the safety belt rope, and lacks multiple protection measures. Once the ladder is deformed or damaged due to uneven force, the safety belt rope will fail and the operator will lose protection. Once a fall occurs, the operator's range of movement is restricted and he cannot move freely inside the tower. This not only reduces work efficiency, but also may increase the risk of operational errors due to frequent adjustments to the safety belt rope. Summary of the Invention

[0005] The present invention provides a safety belt fixing device inside a concrete tower, which is used to solve the problem that in the prior art, the anti-fall rope is fixed on the ladder, the structural strength and stability of which cannot meet the force requirements of the safety belt rope, and the ladder is relied upon alone as the fixing point of the safety belt rope, lacking multiple protection measures. Once the ladder is deformed or damaged due to uneven force, resulting in failure of the safety belt rope, the operator will lose protection in the event of a fall, and at the same time the operator's range of movement is restricted, and he cannot move freely inside the tower.

[0010] Furthermore, a first arc plate is fixedly mounted on the inner wall of the safety belt hanging ring, and a second arc plate is fixedly mounted on the inner wall of the safety belt hook.

[0011] Furthermore, a support frame is fixedly installed on one side of the seat belt hook, an electric telescopic rod is fixedly installed on the support frame, a fastening block is fixedly installed on the output end of the electric telescopic rod, a fastening groove adapted to the fastening block is opened on one side of the closing rod, and an operating switch electrically connected to the electric telescopic rod is fixedly installed on the surface of the groove.

[0014] Furthermore, a fixing frame is fixedly installed on the top and bottom of the battery box, two second springs are symmetrically fixedly installed inside the fixing frame, a limiting rod is fixedly installed on one end of the second spring, and a limiting block is fixedly installed on the top and bottom of the box cover, and the diameter of the limiting rod is equal to the inner diameter of the slot on the limiting block, and one end of the limiting rod is set to an arc shape.

[0016] The present invention provides a safety belt fixing device inside a concrete tower;

[0017] 1. Through the setting of the safety belt fixing structure, it relies on fixing the rail beam on the concrete tower body and setting multiple safety belt hanging rings for fixing the safety belt on the rail beam, and then the safety belt hanging rings are used to connect the safety belt hooks on the safety belt of the workers. When the workers work on the operating platform, the safety belts are fixed by connecting these safety belt hanging rings and the safety belt hooks, ensuring the stability of the construction workers wearing the safety belts and ensuring uniform force.

The safety belt fixing structure is provided with multiple safety belt hanging rings, which enable the workers to fix and adjust the safety belt according to the working scope, thereby improving the protection range and solving the problem that the range of movement of the workers is restricted when the safety belt rope is fixed on the ladder.

[0019] 3. Since the rail beam is set above the operating platform, it follows the principle of high hanging and low use, that is, the safety belt hook is fixed at a position higher than the operator to reduce the impact force in case of falling.

[0020] 4. Since the safety belt hook and the safety belt hanging ring can be quickly disassembled, and the safety anchor fixing plate and the rail beam are clamped and fixed by multiple L-shaped clamping plates, the safety anchor fixing plate can also be disassembled on the rail beam. This allows construction workers to quickly disassemble and assemble to adjust the position of the safety belt hook and the safety belt according to the construction location, saving time and energy. By optimizing the current safety protection device for workers installing concrete tower segments, the stability of the safety belts worn by construction workers can be guaranteed to ensure the safety of the workers.

[0033] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] like Figures 1-11 As shown, an embodiment of the present invention provides an internal safety belt fixing device for a concrete tower, comprising a concrete tower body 1, an operating platform 2 being provided inside the concrete tower body 1, a safety belt fixing structure 3 being provided above the operating platform 2, the safety belt fixing structure 3 comprising a rail beam 4 provided on the inner wall of the concrete tower body 1, a plurality of fixing brackets 5 being fixedly mounted on the rail beam 4, a plurality of bolts 6 being threadedly connected to the concrete tower body 1 being mounted on the fixing bracket 5, a plurality of safety anchor point fixing plates 7 being provided on the inner wall of the fixing bracket 5, a safety belt hanging ring 8 being fixedly mounted on the safety anchor point fixing plate 7, a safety belt hook 9 being movably mounted on the safety belt hanging ring 8, a double-headed safety rope 10 being provided between two adjacent safety belt hooks 9, a groove 21 being provided on the safety belt hook 9, a closing rod 22 being slidably mounted on the groove 21, and a first spring 23 fixedly connected to the closing rod 22 being fixedly mounted on the inner wall of the groove 21. By setting up the safety belt fixing structure 3, relying on fixing the rail beam 4 on the concrete tower body 1 and setting a plurality of safety belt hanging rings 8 for fixing the safety belt on the rail beam 4, and then connecting the safety belt hooks 9 on the safety belt of the operator through the safety belt hanging ring 8, the operator can fix the safety belt through the connection of these safety belt hanging rings 8 and the safety belt hooks 9 when working on the operating platform 2, ensuring the stability of the construction workers wearing the safety belt and ensuring uniform force. In addition, a plurality of safety belt hanging rings 8 are set on the safety belt fixing structure 3, which can enable the workers to fix and adjust the safety belt according to the working scope, thereby improving the protection scope. To ensure safety, the current concrete tower pipe segment installation worker safety protection device can be optimized, thereby ensuring the stability of the construction workers wearing the safety belt and ensuring the safety of the workers.

[0035] like Figures 1-11As shown, the top and bottom of the safety anchor fixing plate 7 are fixedly installed with a support plate 11, and a transmission screw 12 connected by a thread is provided on the support plate 11. Two L-shaped clamping plates 13 are symmetrically and slidably installed on one side of the safety anchor fixing plate 7, and the L-shaped clamping plate 13 and the transmission screw 12 are arranged to be movably connected. A plurality of anti-slip meshing teeth 14 are fixedly installed on the inner wall of the L-shaped clamping plate 13, and a plurality of anti-slip meshing grooves 15 adapted to the anti-slip meshing teeth 14 are provided on the top and bottom of the rail beam 4. Two telescopic plates 16 are symmetrically and movably installed on one end of the transmission screw 12, and a magnetic block 17 is fixedly installed on one end of the telescopic plate 16. A magnetic ring 18 is fixedly installed on the surface of the support plate 11.

[0036] The L-shaped clamping plate 13 is fixed to the rail beam 4 by the arrangement of the support plate 11, the transmission screw 12 and the L-shaped clamping plate 13. The safety anchor point fixing plate 7 is fixedly installed on the rail beam 4 by relying on the clamping of the two L-shaped clamping plates 13 to the rail beam 4. Since the L-shaped clamping plate 13 is supported by the support plate 11 and the transmission screw 12, after the rail beam 4 is clamped, not only the safety anchor point fixing plate 7 is firmly installed on the rail beam 4, but also when the transmission screw 12 is rotated and driven by the threaded transmission with the support plate 11 to drive the L-shaped clamping plate 13 to rise and fall, the two L-shaped clamping plates 13 can be separated so that the safety anchor point fixing plate 7 has a quick-release function, which is convenient for use. The anti-slip meshing teeth 14 and the anti-slip meshing grooves 15 are arranged. After the L-shaped clamping plate 13 clamps the rail beam 4, the anti-slip meshing teeth 14 and the anti-slip meshing grooves 15 are arranged. The meshing teeth 14 are inserted into the anti-slip meshing grooves 15 provided on the rail beam 4. The meshing connection between the anti-slip meshing teeth 14 and the anti-slip meshing grooves 15 can improve the tightness of the connection between the L-shaped clamping plate 13 and the rail beam 4, preventing the L-shaped clamping plate 13 from sliding on the rail beam 4, further improving the firmness of the installation of the safety anchor point fixing plate 7. Through the arrangement of the telescopic plate 16, the magnetic block 17 and the magnetic ring 18, the two L-shaped clamping plates 13 are adjusted and clamped on the rail beam 4 to fix the safety anchor point fixing plate 7. At this time, the telescopic plate 16 is flipped and extended so that the magnetic block 17 on one end is magnetically attracted to the magnetic ring 18, and the transmission screw 12 is limited and fixed by the effect of magnetic attraction to prevent the transmission screw 12 from loosening after collision, so as to ensure that the L-shaped clamping plate 13 always clamps the rail beam 4 tightly.

[0037] like Figures 1-11As shown, a first arc plate 19 is fixedly mounted on the inner wall of the seat belt hanging ring 8, a second arc plate 20 is fixedly mounted on the inner wall of the seat belt hook 9, a support frame 24 is fixedly mounted on one side of the seat belt hook 9, an electric telescopic rod 25 is fixedly mounted on the support frame 24, a fastening block 26 is fixedly mounted on the output end of the electric telescopic rod 25, a fastening groove 27 adapted to the fastening block 26 is provided on one side of the closing rod 22, an operating switch 28 electrically connected to the electric telescopic rod 25 is fixedly mounted on the surface of the groove 21, a first mounting groove 29 is provided on one end of the seat belt hook 9, an infrared position sensor 30 is fixedly mounted inside the first mounting groove 29, a second mounting groove 31 is provided at one end of the closing rod 22, and a sensing block 32 is fixedly mounted inside the second mounting groove 31.

[0038] By setting the first arc plate 19 and the second arc plate 20, the friction between the safety belt loop 8 and the safety belt hook 9 can be reduced, thereby reducing the wear and tear on the safety belt loop 8 and the safety belt hook 9 and improving the service life. By setting the support frame 24, the electric telescopic rod 25, the fastening block 26, the fastening groove 27 and the operating switch 28, the safety belt hook 9 is hung on the safety belt loop 8 and closed by the closing rod 22, and then the electric telescopic rod 25 is started to extend its output end to insert the fastening block 26 into the fastening groove 27 provided on the closing rod 22. After the fastening block 26 and the fastening groove 27 are connected, the closing rod 22 can be fixed for the second time, effectively preventing the closing rod 22 from loosening and avoiding the safety belt hook 9 falls off from the safety belt hanging ring 8, and the setting of the operating switch 28 is convenient for the operator to open and close the electric telescopic rod 25. Through the setting of the first mounting slot 29, the infrared position sensor 30, the second mounting slot 31 and the sensing block 32, the infrared position sensor 30 and the sensing block 32 cooperate to monitor the closing state of the closing rod 22 and the safety belt hook 9 at all times. After the operator hangs the safety belt hook 9 on the safety belt hanging ring 8, if the closing rod 22 is not closed on the safety belt hook 9 or is loose on the safety belt hook 9, the infrared position sensor 30 will sound an alarm when it does not detect the sensing block 32, so that the staff can check the safety belt hook 9 for tightening, thereby further improving safety.

[0039] like Figures 1-11As shown, a battery box 33 is fixedly installed on the surface of the safety belt hook 9, and a box cover 34 is provided on one side of the battery box 33. The interior of the battery box 33 is provided with a battery 35 electrically connected to the electric telescopic rod 25 and the infrared position sensor 30. The top and bottom of the battery box 33 are fixedly installed with a fixing frame 36, and two second springs 37 are symmetrically fixedly installed inside the fixing frame 36. One end of the second spring 37 is fixedly installed with a limiting card rod 38, and the top and bottom of the box cover 34 are fixedly installed with a limiting card block 39, and the diameter of the limiting card rod 38 is equal to the inner diameter of the card groove on the limiting card block 39. At the same time, one end of the limiting card rod 38 is set as the bottom of the arc-shaped safety belt hook 9 and is fixedly installed with a threaded cylinder 40, and the double-headed safety rope 10 is fixedly installed with a threaded block 41 threadedly connected to the threaded cylinder 40.

[0040] The battery box 33, the box cover 34 and the battery 35 are arranged so as to electrically connect the battery 35, the infrared position sensor 30 and the electric telescopic rod 25, and can provide power supply for the infrared position sensor 30 and the electric telescopic rod 25 at all times. The box cover 34 is arranged so as to be mounted on the battery box 33 by means of the fixing frame 36, the second spring 37, the limit card rod 38 and the limit card block 39, and the box cover 34 is mounted on the battery box 33 by means of the engagement of the plurality of limit card rods 38 and the limit card block 39. This allows the box cover 34 to be removed from the battery box 33, thereby facilitating the replacement of the battery 35 inside the battery box 33. The disassembly process is to directly pull the box cover 34 so that the limit card blocks 39 on both sides squeeze and contract the limit card rods 38 to disengage them. After the engagement is cancelled, the box cover 34 can be removed. During installation, the limit card blocks 39 on both sides of the box cover 34 are inserted into the fixing frame 36. When the locking cam 38 is in the same position as the locking cam 39, the locking cam 38 is reset and inserted into the locking cam 39 under the elastic support of the second spring 37, thereby completing the fixation of the box cover 34. When the diameter of the limiting card rod 38 is equal to the inner diameter of the locking cam 39, the two can be tightly connected to prevent the box cover 34 from shaking and falling off. After one end of the limiting card rod 38 is set to an arc, it is easier for the limiting card block 39 to squeeze the limiting card rod 38 during installation and removal. Through the arrangement of the threaded barrel 40 and the threaded block 41, the safety belt hook 9 and the double-headed safety rope 10 are connected by the threaded barrel 40 and the threaded block 41. By rotating the threaded block 41, the safety belt hook 9 and the double-headed safety rope 10 can be connected and separated with the threaded barrel 40, which is convenient for replacing the double-headed safety rope 10 when it is worn.

[0041] The working principle and use process of the present invention:

[0042] Step 1: Fix the rail beam 4 to the inner wall of the concrete tower body 1 and above the operating platform 2 through multiple fixing brackets 5 and bolts 6, then set multiple safety anchor fixing plates 7 on the rail beam 4, rotate the transmission screw 12 to drive the L-shaped clamping plate 13 through the thread between the support plate 11, so that the two L-shaped clamping plates 13 move closer to each other to clamp the rail beam 4, and the anti-slip meshing teeth 14 on the inner wall of the L-shaped clamping plate 13 are inserted into the anti-slip meshing groove 15 opened on the rail beam 4. The meshing connection of the meshing groove 15 can improve the tightness of the connection between the L-shaped clamping plate 13 and the rail beam 4, preventing the L-shaped clamping plate 13 from sliding on the rail beam 4. After the two L-shaped clamping plates 13 are adjusted and clamped on the rail beam 4 to fix the safety anchor point fixing plate 7, the telescopic plate 16 is flipped and extended, so that the magnetic block 17 on one end is magnetically attracted to the magnetic ring 18, and the transmission screw 12 is limited and fixed by the magnetic effect, preventing the transmission screw 12 from loosening after being hit, thereby fixing the safety anchor point fixing plate 7 on the rail beam 4;

[0043] Step 2: After completing the fixation of the safety anchor point fixing plate 7, hang the safety belt hook 9 at one end of the double-headed safety rope 10 on the safety belt on the safety belt hanging ring 8, and then close the closing rod 22 on the safety belt hook 9, and then start the electric telescopic rod 25 by operating the switch 28. Start the electric telescopic rod 25 to extend its output end and insert the fastening block 26 into the fastening groove 27 opened on the closing rod 22. After connecting the fastening block 26 and the fastening groove 27, the closing rod 22 can be fixed for the second time, and the safety belt can be fixed. After the closing rod 22 and the safety belt hook 9 are closed, the red The external position sensor 30 and the sensing block 32 cooperate to monitor the closing state of the closing rod 22 and the safety belt hook 9 at all times. After the operator hangs the safety belt hook 9 on the safety belt hanging ring 8, if the closing rod 22 is not closed on the safety belt hook 9 or becomes loose on the safety belt hook 9, the infrared position sensor 30 will sound an alarm when it fails to detect the sensing block 32, prompting the operator to check and tighten the safety belt hook 9, thereby protecting the operator and ensuring safe construction. When changing the working position, the safety belt hook 9 can be removed from the safety belt hanging ring 8 and replaced in a fixed position.

[0044] Step 3, the battery 35 can always provide power supply for the infrared position sensor 30 and the electric telescopic rod 25. When the battery 35 is low on power, the box cover 34 is removed from the battery box 33. The removal process is to pull the box cover 34 so that the limit blocks 39 on both sides squeeze and shrink the limit rod 38 to disengage. After the engagement is cancelled, the box cover 34 can be disassembled, and then the battery 35 is taken out of the battery box 33 and replaced. After the battery 35 is replaced, the box cover 34 is installed on the battery box 33. During installation, the limit blocks 39 on both sides of the box cover 34 are inserted into the fixing frame 36, and the limit rod 38 is squeezed and shrunk. The card slots on the limit blocks 39 and the limit rod 38 are engaged. When they are in the same position, the limit card rod 38 is reset and inserted into the card slot under the elastic support of the second spring 37 and engages with the limit card block 39, thereby completing the fixation of the box cover 34. When the double-headed safety rope 10 on the safety belt is worn and broken, in order to ensure the safety of the construction workers, the double-headed safety rope 10 needs to be replaced. Since the threaded block 41 on one end of the double-headed safety rope 10 is threadedly connected to the threaded barrel 40 at the bottom of the safety belt hook 9, the threaded block 41 can be directly rotated to detach from the threaded barrel 40 along the thread. After disassembly, the double-headed safety rope 10 can be replaced. During installation, the threaded block 41 is also docked at the bottom of the threaded barrel 40, and the threaded connection is completed by rotation to complete the replacement and installation of the double-headed safety rope 10.
