Description

Technical Field

[0001] The invention relates to the technical field of construction equipment, and in particular to a safety guardrail used for offshore duct-type wind turbine foundation construction. Background Art

[0002] The wind turbine foundation is the base of the wind turbine tower, bearing its entire weight and shouldering all stress conditions including support, earthquake resistance, strong wind resistance, etc. However, when the foundation construction of the duct-mounted wind turbine is carried out on the offshore platform, people often approach or enter the construction site, causing a series of safety hazards. Therefore, for safety reasons, guardrails must be erected at the construction site. At present, the guardrails and the base are usually fixed by welding, but the welding method makes the fixing of the guardrails more complicated and can only be performed by welding workers, which makes the fixing of the guardrails more inconvenient, thereby reducing the connection efficiency.

[0003] To solve the above problems, the connection method between the guardrail and the base is replaced by bolt connection on the market. A number of threaded holes are first opened on the base, and round holes matching the threaded holes are opened on the guardrail. Then the guardrail is placed on the base and the round holes are aligned with the threaded holes. After the guardrail is placed, the workers screw the bolts into the threaded holes along the round holes one by one. In this way, the workers use bolts to connect the guardrail and the base. The connection process does not require designated welding workers to connect, and the connection method is also relatively simple, thereby improving the connection efficiency.

[0004] The above-mentioned device has the following problems during actual use: 1. During the placement of the guardrail, workers are required to adjust the position of the guardrail multiple times to ensure that the round hole on the guardrail can face the threaded hole, so that the guardrail can be installed normally. However, since the position of the guardrail needs to be adjusted manually multiple times, the workload of the workers is increased, the work is cumbersome, and the connection efficiency is reduced; 2. After the round hole on the guardrail faces the threaded hole, it is still necessary to manually tighten the bolts and connect them with the threaded holes to complete the installation and fixation of the guardrail, that is, to achieve the positioning of the guardrail, but manual operation adds unnecessary trouble to the workers' work and reduces the connection efficiency. Summary of the invention

[0005] The present invention provides a safety guardrail for offshore duct frame type wind turbine foundation construction, so as to solve the problem that the existing guardrail needs to manually screw bolts multiple times, which is a relatively cumbersome process.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: it includes a mounting seat, a base, a guardrail, and a bottom groove opened on the mounting seat; the base is connected to the bottom groove, the guardrail is fixedly connected to the base, and also includes an auxiliary mechanism symmetrically arranged on both sides of the mounting seat along the width direction of the mounting seat; the auxiliary mechanism includes a mounting block, a first wedge block, an auxiliary groove opened on the mounting seat, a wedge surface groove opened on the bottom groove, a mounting hole opened on the base, and auxiliary components symmetrically arranged on both sides of the mounting seat along the length direction of the auxiliary groove; the two ends of the mounting hole are respectively connected to the auxiliary groove and the wedge surface groove, and the mounting block is slidably connected to the auxiliary groove; the first wedge block is fixedly connected to the mounting block, and the wedge surface groove is located on the movement trajectory of the first wedge block; the auxiliary component includes a slider, an expansion block, a slide groove opened on the auxiliary groove, an expansion groove opened in the mounting block, and a driving part for driving the slider to move along the length direction of the slide groove; the slider is slidably connected to the slide groove, and the expansion block is fixedly connected to the slider; the expansion groove is located on the movement trajectory of the expansion block.

[0007] The principles and advantages of this solution are:

[0008] 1. Place the base into the bottom groove, and then use the robot arm to push the mounting blocks on both sides so that the mounting blocks move along the length direction of the auxiliary groove to the position close to the wedge groove. During the movement of the mounting block, the first wedge block moves synchronously until the first wedge block slides into the wedge groove through the mounting hole, and then the first wedge block stops moving. During the period when the first wedge block stops moving, the base and the wedge groove can be connected to form a whole, so that the base will not shake left and right. That is, through the joint action of the first wedge block and the mounting block, the base can be initially fixed, preparing for the subsequent further fixation of the mounting block.

[0009] 2. While the mounting block slides into the mounting hole, the driving unit drives the slider to move toward the position close to the mounting block. During the movement of the slider, the expansion block moves synchronously. During the movement of the expansion block, until the expansion block slides into the expansion slot, the expansion block is squeezed and deformed, that is, the expansion block can fill the expansion slot, and at this time, both the expansion block and the mounting block stop moving. Through the above movement, the mounting block is clamped under the joint action of the two expansion blocks, that is, the mounting block will not shake under the influence of changes in external environmental factors or interference from human factors, thereby enhancing the fixing effect of the mounting block on the base.

[0010] In summary, under the action of the first wedge block, the first wedge block is connected to the bottom groove to form a whole; under the action of the mounting block, the base is connected to the bottom groove to form a whole; finally, under the action of the expansion block, the mounting block is fixed. The whole process is simple and easy to operate, the installation is fast and efficient, and it ensures that the base is firmly fixed on the mounting seat.

[0011] Furthermore, the auxiliary component also includes a reinforcement part; the reinforcement part includes a second wedge block, a side groove opened on the base, and a side groove opened on the bottom groove; the side groove is communicated with the mounting hole, the second wedge block is slidably connected to the side groove, and the second wedge block is located on the movement trajectory of the first wedge block; the side groove is communicated with the side groove, and the side groove is located on the movement trajectory of the second wedge block.

[0012] During the movement of the first wedge block, since the second wedge block is located on the movement track of the first wedge block, the second wedge block can move to the position close to the side groove under the action of the first wedge block. During the movement of the second wedge block, the second wedge block stops moving until the second wedge block slides into the side groove. Through the mutual cooperation between the second wedge block and the side groove, the base is further reinforced from different directions, thereby increasing the diversity of the base reinforcement, enhancing the effect of the base reinforcement, and improving the stability of the connection between the base and the bottom groove.

[0013] Furthermore, the auxiliary component also includes a positioning part; the positioning part includes a screw, a guide rod, a nut seat, a positioning block, a power unit for driving the screw to rotate, and a positioning groove opened on the mounting seat; the positioning groove is communicated with the bottom groove; the screw is rotatably connected to the positioning groove; the guide rod is fixedly connected to the positioning groove; the nut seat is threadedly connected to the screw, and the nut seat is slidably connected to the guide rod; the positioning block is fixedly connected to the nut seat, and the base is located on the movement trajectory of the positioning block.

[0014] The screw is driven to rotate by the power unit. During the rotation of the screw, the nut seat can move along the length direction of the guide rod to a position close to the base. During the movement of the nut seat, the nut seat can drive the positioning block to move close to the base. During the movement of the positioning block, the positioning block stops moving until the positioning block contacts the base. During the movement of the positioning block, the positioning block can squeeze the base, so that the base and the bottom groove fit more closely. That is, the connection between the base and the bottom groove is more stable and firm, further enhancing the fixing effect of the base.

[0015] To sum up, under the joint action of the first wedge block, the mounting block, the expansion block, the second wedge block and the positioning block, the base can be firmly fixed without shaking or shifting, which comprehensively enhances the reinforcement effect of the base and ensures the quality of the reinforced base.

[0016] Furthermore, the reinforcement part also includes a warning unit; the warning unit includes a connecting block, a first electrode sheet, a second electrode sheet, and a warning light; the connecting block is connected to the second wedge block; the first electrode sheet is fixedly connected to the connecting block; the second electrode sheet is fixedly connected to the side groove, and the second electrode sheet is located on the movement trajectory of the first electrode sheet; the warning light is fixedly connected to the top of the mounting seat; the first electrode sheet, the second electrode sheet, the warning light, and the power supply are connected by wires to form a series circuit.

[0017] During the movement of the second wedge block, the second wedge block can drive the first electrode sheet to move toward the position close to the second electrode sheet. During the movement of the first electrode sheet, until the first electrode sheet contacts the second electrode sheet and is energized, the warning light emits green light. After the warning light emits green light, on the one hand, it can remind the workers that the first wedge block, the second wedge block, the installation block, the positioning block, and the expansion block have reached the specified position, that is, it can intuitively and accurately help the workers to judge that the installation and fixation of the base and the bottom groove have been completed, that is, the base and the bottom groove are connected to form an integral whole, thereby improving the convenience and practicality during the installation of the base; on the other hand, it can continuously monitor whether the base is loose, that is, while the warning light continues to emit green light, it can ensure that the base is always firmly connected to the bottom groove without loosening. If the green light is no longer emitted, it will remind the workers to promptly perform remedial reinforcement operations on the base, eliminating safety hazards and reducing the probability of risk accidents.

[0018] Furthermore, the reinforcement part also includes a linkage part; the linkage part includes a linkage block, a through hole opened on the second wedge block, and a linkage groove opened on the mounting block; the linkage block is slidably connected to the through hole, and the linkage block is fixedly connected to the connecting block; the mounting block is located on the motion track of the linkage block, and the linkage block is used to slide into the linkage groove.

[0019] During the contact between the first electrode sheet and the second electrode sheet, the linkage block moves along the length direction of the through hole to the position close to the mounting block under the reaction force of the first electrode sheet. During the movement of the linkage block, the linkage block stops moving until the linkage block slides into the linkage groove. While the linkage block is in the linkage groove, the linkage block can further reinforce the mounting block, making the connection between the mounting block and the base more comprehensive and thorough, that is, improving the stability of the mounting block, ensuring that the mounting block will not shake due to changes in external environmental factors or interference from human factors, so that the base can be firmly fixed under the action of the mounting block.

[0020] Furthermore, a wedge surface is provided on the linkage block; it also includes an auxiliary part arranged on the mounting block; the auxiliary part includes an auxiliary block, a third wedge block, a guide groove opened on the first wedge block, a chamber opened in the mounting block, and a limit groove opened on the wedge surface groove; the auxiliary block is slidably connected to the guide groove, and the limit groove is located on the movement trajectory of the auxiliary block; the chamber is respectively communicated with the linkage groove and the guide groove, the third wedge block is slidably connected to the chamber, the third wedge block is fixed to the auxiliary block, and the third wedge block is located on the movement trajectory of the wedge surface.

[0021] The linkage block drives the wedge surface to slide into the linkage groove until the wedge surface contacts the third wedge block, so that the third wedge block can drive the auxiliary block to move close to the position where the limit groove is located. During the movement of the auxiliary block, the auxiliary block stops moving until the auxiliary block slides into the limit groove. During the period when the auxiliary block stops moving, the reinforcement effect of the wedge surface groove on the first wedge block can be enhanced, so that the first wedge block and the wedge surface groove have a higher fit, and the stability of the first wedge block is improved. That is, the connection quality of the first wedge block and the wedge surface groove is guaranteed, and the connection between the base and the bottom groove is more stable.

[0022] To sum up, through the further reinforcement of the mounting block by the linkage block and the further reinforcement of the first wedge block by the auxiliary block, the reinforcement effect of the mounting block and the first wedge block on the base is comprehensively enhanced, the stability during the connection between the base and the bottom groove is improved, and it is ensured that the base is firmly fixed in the bottom groove without displacement and shaking.

[0023] Furthermore, it also includes connecting parts symmetrically arranged on both sides of the third wedge block along the length direction of the third wedge block; the connecting parts include a top block and a hook; the top block is fixedly connected to the third wedge block; the hook is hinged to the top block; a hollow ring is fixedly connected to the linkage block; the hook is located on the movement trajectory of the hollow ring, and the hollow ring is used to limit the movement of the hook.

[0024] During the movement of the third wedge block, the hook moves synchronously. During the movement of the hook, when the linkage block drives the hollow ring to slide into the chamber, the hollow ring can squeeze the moving hook, causing the hook to swing. During the gradual swinging of the hook, the hook also sticks to the outer wall of the hollow ring until the hollow ring passes over the free end of the hook, so that the free end of the hollow ring can stick to the inner wall of the hollow ring. Through the above movement, while the hook sticks to the inner wall of the hollow ring, the linkage block and the third wedge block can be connected to form a whole, thereby making the connection between the linkage block and the third wedge block tighter, that is, the mounting block is further fixed, ensuring that the mounting block can be firmly fixed in the mounting hole, and improving the stability of the mounting block.

[0026] During the movement of the second wedge block, the first rack moves synchronously. During the movement of the first rack, the first rack meshes with the first gear, thereby causing the first gear to rotate. During the rotation of the first gear, the first gear meshes with the second rack, thereby causing the second rack to move along the length direction of the slide slot toward the position where the mounting block is located.

[0027] Furthermore, it also includes a power part; the power part includes a power shaft, a second gear, a second rack, a connecting groove opened on the mounting block, and a rotating groove opened on the auxiliary groove; the power shaft is rotatably connected to the rotating groove, and the two ends of the power shaft extend into the two positioning grooves respectively; the power unit includes a worm and a worm wheel; the worm is rotatably connected to the positioning groove; the worm wheel is fixedly connected to the screw, and the worm wheel is meshed with the worm.

[0028] During the movement of the mounting block, the second rack moves synchronously. During the movement of the second rack, when the second rack meshes with the second gear, the second gear rotates; during the rotation of the second gear, the power shaft rotates synchronously. During the rotation of the power shaft, the worm rotates synchronously. During the rotation of the worm, the worm meshes with the worm wheel, so that the worm wheel rotates. During the rotation of the worm wheel, the screw rotates synchronously. During the rotation of the screw, the nut seat can drive the positioning block to move to a position close to the base.

[0052] Specific implementation process:

[0053] During the foundation construction of the duct frame wind turbine, in order to avoid intrusion or interference by unrelated personnel, during this period, the base 2 is placed in the bottom groove, and then the workers use the mechanical arm to push the mounting blocks 4 on both sides, so that the mounting blocks 4 move along the length direction of the auxiliary groove 6 to the position close to the wedge groove 7. During the movement of the mounting block 4, the first wedge block 5 moves synchronously until the first wedge block 5 slides into the wedge groove 7 through the mounting hole 41, and then the first wedge block 5 stops moving. During the period when the first wedge block 5 stops moving, the base 2 can be connected to the wedge groove 7 to form a whole, so that the base 2 will not shake left and right. That is, through the joint action of the first wedge block 5 and the mounting block 4, the base 2 can be initially fixed, and preparations can be made for further fixing of the mounting block 4 later.

[0054] During the period when the mounting block 4 slides into the mounting hole 41, since the second wedge block 11 is located on the movement track of the first wedge block 5, the second wedge block 11 can move to the position close to the side groove 12 under the action of the first wedge block 5. During the movement of the second wedge block 11, the second wedge block 11 stops moving until the second wedge block 11 slides into the side groove 12. Through the mutual cooperation between the second wedge block 11 and the side groove 12, the base 2 is further reinforced from different directions, thereby increasing the diversity of the reinforcement of the base 2, enhancing the reinforcement effect of the base 2, and improving the stability of the connection between the base 2 and the bottom groove.

[0055] During the movement of the second wedge block 11, the first rack 33 moves synchronously.

During the rotation of the first gear 32, the first gear 32 is meshed with the second rack 37, so that the second rack 37 moves along the length direction of the slide slot 10 toward the position where the mounting block 4 is located.

[0056] During the movement of the second rack 37, the slider 8 moves synchronously. During the movement of the slider 8 toward the position where the mounting block 4 is located, the expansion block 9 moves synchronously. During the movement of the expansion block 9, until the expansion block 9 slides into the expansion groove 45, the expansion block 9 is squeezed and deformed, that is, the expansion block 9 can fill the expansion groove 45, and at this time, the expansion block 9 and the mounting block 4 both stop moving. Through the above movement, the mounting block 4 is clamped under the joint action of the two expansion blocks 9, that is, the mounting block 4 will not shake under the influence of changes in external environmental factors or interference from human factors, thereby enhancing the fixing effect of the mounting block 4 on the base 2.

[0057] Through the above movement, under the action of the first wedge block 5, the first wedge block 5 is connected to the bottom groove to form a whole; then under the action of the mounting block 4, the base 2 is connected to the bottom groove to form a whole; finally, under the action of the expansion block 9, the mounting block 4 is fixed. The whole process is simple and easy to operate, the installation is fast and efficient, and it ensures that the base 2 is firmly fixed on the mounting seat 1.

[0058] During the movement of the mounting block 4, the second rack 37 moves synchronously. During the movement of the second rack 37, when the second rack 37 meshes with the second gear 36, the second gear 36 rotates; during the rotation of the second gear 36, the power shaft 35 rotates synchronously. During the rotation of the power shaft 35, the worm 39 rotates synchronously. During the rotation of the worm 39, the worm 39 meshes with the worm wheel 40, so that the worm wheel 40 rotates. During the rotation of the worm wheel 40, the screw 13 rotates synchronously. During the rotation of the screw 13, the nut seat 15 can drive the positioning block 16 to move to a position close to the base 2.

[0059] During the movement of the positioning block 16 toward the position where the base 2 is located, the positioning block 16 stops moving until the positioning block 16 abuts against the base 2. During the movement of the positioning block 16, the positioning block 16 can squeeze the base 2, so that the base 2 and the bottom groove fit more closely. That is, the connection between the base 2 and the bottom groove is more stable and firm, further enhancing the fixing effect of the base 2.

[0060] To sum up, under the joint action of the first wedge block 5, the mounting block 4, the expansion block 9, the second wedge block 11, and the positioning block 16, the base 2 can be firmly fixed without shaking or shifting, thereby comprehensively enhancing the reinforcement effect of the base 2 and ensuring the quality of the reinforcement of the base 2.

[0061] During the movement of the second wedge block 11, the second wedge block 11 can drive the first electrode sheet 19 to move to a position close to the second electrode sheet 20. During the movement of the first electrode sheet 19, until the first electrode sheet 19 contacts the second electrode sheet 20 and is energized, the warning light 21 emits green light. After the warning light 21 emits green light, on the one hand, it can remind the workers that the first wedge block 5, the second wedge block 11, the mounting block 4, the positioning block 16, and the expansion block 9 have reached the specified position, that is, it can intuitively and accurately help the workers to judge that the installation and fixation of the base 2 and the bottom groove have been completed, that is, the base 2 and the bottom groove are connected to form an integral body, thereby improving the convenience and practicality during the installation of the base 2; on the other hand, it can continuously monitor whether the base 2 is loose, that is, during the period when the warning light 21 continues to emit green light, it can ensure that the base 2 is always firmly connected to the bottom groove and there is no looseness. If the green light is no longer emitted, it will remind the workers to promptly perform remedial reinforcement operations on the base 2, eliminating safety hazards and reducing the probability of risk accidents.

[0062] During the contact between the first electrode sheet 19 and the second electrode sheet 20, the linkage block 22 moves along the length direction of the through hole 23 to the position close to the mounting block 4 under the reaction force of the first electrode sheet 19. During the movement of the linkage block 22, the linkage block 22 stops moving until the linkage block 22 slides into the linkage groove 24. While the linkage block 22 is in the linkage groove 24, the linkage block 22 can further reinforce the mounting block 4, making the connection between the mounting block 4 and the base 2 more comprehensive and thorough, that is, improving the stability of the mounting block 4, ensuring that the mounting block 4 will not shake due to changes in external environmental factors or interference from human factors, so that the base 2 can be firmly fixed under the action of the mounting block 4.

[0063] The linkage block 22 drives the wedge surface 25 to slide into the linkage groove 24 until the wedge surface 25 contacts the third wedge block 27, so that the third wedge block 27 can drive the auxiliary block 26 to move to a position close to the limit groove 30. During the movement of the auxiliary block 26, the auxiliary block 26 stops moving until the auxiliary block 26 slides into the limit groove 30. During the stop of the auxiliary block 26, the reinforcement effect of the wedge surface groove 7 on the first wedge block 5 can be enhanced, so that the first wedge block 5 and the wedge surface groove 7 have a higher fit, and the stability of the first wedge block 5 is improved. That is, the connection quality of the first wedge block 5 and the wedge surface groove 7 is guaranteed, and the connection between the base 2 and the bottom groove is more stable.

[0064] In summary, through the further reinforcement of the mounting block 4 by the linkage block 22 and the further reinforcement of the first wedge block 5 by the auxiliary block 26, the reinforcement effect of the mounting block 4 and the first wedge block 5 on the base 2 is comprehensively enhanced, and the stability during the connection between the base 2 and the bottom groove is improved, ensuring that the base 2 is firmly fixed in the bottom groove without displacement and shaking.

[0065] During the movement of the third wedge block 27, the hook 43 moves synchronously. During the movement of the hook 43, when the linkage block 22 drives the hollow ring 44 to slide into the chamber 29, the hollow ring 44 can squeeze the hook 43 in motion, causing the hook 43 to swing. During the gradual swinging of the hook 43, the hook 43 also sticks to the outer wall of the hollow ring 44 until the hollow ring 44 passes over the free end of the hook 43, so that the free end of the hollow ring 44 can stick to the inner wall of the hollow ring 44. Through the above movement, during the period when the hook 43 sticks to the inner wall of the hollow ring 44, the linkage block 22 and the third wedge block 27 can be connected to form a whole, thereby making the connection between the linkage block 22 and the third wedge block 27 tighter, that is, the mounting block 4 is further fixed, ensuring that the mounting block 4 can be firmly fixed in the mounting hole 41, and improving the stability of the mounting block 4.
