Description

TECHNICAL FIELD

[0001] The present application relates to the construction equipment technical field, specifically to a kind of safety guardrails for offshore jacket type wind turbine foundation construction. BACKGROUND

[0002] The wind turbine foundation is the base of the wind turbine tower, which bears the entire weight and supports, seismic, strong wind resistance and other conditions. But when the foundation construction of jacket type wind turbine is carried out on the offshore platform, people often approach or enter the construction site, causing a series of safety hazards. Therefore, in order to ensure safety during construction, protective fences must be erected in the construction site. At present, the protective fence and the base are usually fixed by welding. However, the fixing of the protective fence is more complicated by welding, and only welders can perform the fixing connection operation, which makes the fixing of the protective fence more inconvenient and reduces the connection efficiency.

[0003] To solve the above problems, the connection method of the protective fence and the base is replaced by bolt connection on the market. A plurality of threaded holes are first opened on the base, and matching threaded holes are opened on the protective fence. Then the protective fence is placed on the base and the round hole is aligned with the threaded hole. After the protective fence is placed, the worker screws the bolt into the threaded hole along the round hole one by one. By the above method, the worker connects the protective fence and the base with bolts, and the connection process does not need to specify welders to connect, and the connection method is relatively simple, thereby improving the connection efficiency.

[0004] The above device has the following problems in actual use: 1. During the placement of the protective fence, the worker needs to adjust the position of the protective fence several times to ensure that the round hole on the protective fence is directly opposite the threaded hole, so that the protective fence can be normally installed. However, the worker needs to adjust the position of the protective fence several times manually, which increases the workload of the worker and makes the work tedious, thereby reducing the connection efficiency; 2. After the round hole on the protective fence is directly opposite the threaded hole, the worker still needs to manually screw the bolt and the threaded hole to complete the installation and fixation of the protective fence, that is, to realize the positioning of the protective fence. However, manual operation increases unnecessary trouble for the worker during work, which reduces the connection efficiency. SUMMARY

[0005] The present application provides a kind of safety guardrails for offshore jacket type wind turbine foundation construction to solve the problem that the existing protective fence needs to manually screw the bolt several times, which is relatively complicated.

[0006] In order to achieve the above object, the present application adopts the following technical scheme: including a mounting seat, a base, a guardrail, a bottom groove opened on the mounting seat; the base is connected with the bottom groove, and the guardrail is fixedly connected with the base, further including 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 groove opened on the bottom groove, a mounting hole opened on the base, an auxiliary assembly 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 communicated with the auxiliary groove and the wedge groove respectively, and the mounting block is slidably connected with the auxiliary groove; the first wedge block is fixedly connected with the mounting block, and the wedge groove is located on the movement track of the first wedge block; the auxiliary assembly includes a sliding block, an expansion block, a sliding groove opened on the auxiliary groove, an expansion groove opened in the mounting block, and a driving part for driving the sliding block to move along the length direction of the sliding groove; the sliding block is slidably connected with the sliding groove, and the expansion block is fixedly connected with the sliding block; the expansion groove is located on the movement track of the expansion block.

[0007] The principle and advantages of the present application are as follows:

[0008] 1, the base is put into the bottom groove, and then the worker pushes the mounting blocks on both sides by using the mechanical arm, 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 stop of the first wedge block, the base is connected with the wedge groove to form an integral, so that the base does not shake left and right. That is, through the joint action of the first wedge block and the mounting block, the base can be preliminarily fixed, so as to prepare for further fixing of the mounting block.

[0009] 2, during the sliding of the mounting block into the mounting hole, the sliding block is driven by the driving part to move to the position close to the mounting block. During the movement of the sliding block, the expansion block moves synchronously. During the movement of the expansion block, until the expansion block slides into the expansion groove, the expansion block is extruded to deform, that is, the expansion block can fill the expansion groove, and then 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 does not shake under the influence of external environmental factors or human factors, and the fixing effect of the mounting block on the base is enhanced.

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

[0011] Further, the auxiliary assembly further comprises a reinforcing part; the reinforcing part comprises a second wedge, an edge slot opened on the base, and a side slot opened on the bottom slot; the edge slot is communicated with the mounting hole, the second wedge is slidably connected with the edge slot, and the second wedge is located on the movement track of the first wedge; the edge slot is communicated with the side slot, and the side slot is located on the movement track of the second wedge.

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

[0013] Further, the auxiliary assembly further comprises a positioning part; the positioning part comprises a screw rod, a guide rod, a nut seat, a positioning block, a power unit for driving the screw rod to rotate, and a positioning slot opened on the mounting base; the positioning slot is communicated with the bottom slot; the screw rod is rotatably connected with the positioning slot; the guide rod is fixedly connected with the positioning slot; the nut seat is threadedly connected with the screw rod and slidably connected with the guide rod; the positioning block is fixedly connected with the nut seat, and the base is located on the movement track of the positioning block.

[0014] The screw rod is driven to rotate by the power unit, and during the rotation of the screw rod, the nut seat can move towards the position where the base is located along the length direction of the guide rod. During the movement of the nut seat, the nut seat can drive the positioning block to move towards the position where the base is located. During the movement of the positioning block, the positioning block stops moving until the positioning block abuts against the base. During the stop of the movement of the positioning block, the positioning block can press the base, so that the base has a higher fit degree with the bottom slot. That is, the connection between the base and the bottom slot is more stable and firm, and the fixing effect of the base is further enhanced.

[0015] In summary, under the joint action of the first wedge, the mounting block, the expansion block, the second wedge, and the positioning block, the base can be firmly fixed and will not shake or deviate, the reinforcing effect of the base is comprehensively enhanced, and the quality of the reinforced base is ensured.

[0016] Further, the reinforcing part further comprises a warning unit; the warning unit comprises a connecting block, a first electrode sheet, a second electrode sheet, and a warning lamp; the connecting block is connected with the second wedge; the first electrode sheet is fixedly connected with the connecting block; the second electrode sheet is fixedly connected with the side slot and located on the movement track of the first electrode sheet; the warning lamp is fixedly connected with the top of the mounting base; the first electrode sheet, the second electrode sheet, the warning lamp, and a power supply are connected by wires to form a series circuit.

[0017] During the movement of the second wedge, the second wedge can drive the first electrode sheet to move to 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 electrified, the warning light emits green light. After the warning light emits green light, on the one hand, it can prompt the worker that the first wedge, the second wedge, the mounting block, the positioning block and the expansion block have reached the specified position, that is, it intuitively and accurately helps the worker 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, during the continuous emission of green light by the warning light, it can ensure that the base is always connected firmly with the bottom groove and does not loosen. If the green light is no longer emitted, it prompts the worker to timely remedy and reinforce the base, eliminates the safety hidden danger and reduces the probability of risk accidents.

[0018] Further, the reinforcing part further comprises a linkage member; the linkage member comprises a linkage block, a through hole opened on the second wedge, and a linkage groove opened on the mounting block; the linkage block is in sliding connection with the through hole, and the linkage block is fixedly connected with the connecting block; the mounting block is located on the movement track of the linkage block, and the linkage block is used for sliding into the linkage groove.

[0019] During the contact of 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, until the linkage block slides into the linkage groove, the movement of the linkage block stops. During the period when the linkage block is located in the linkage groove, the linkage block can further reinforce the mounting block, so that the connection of the mounting block and the base is more comprehensive and complete, that is, the stability of the mounting block is improved, so that the mounting block can be firmly fixed under the action of the mounting block.

[0020] Further, the linkage block is provided with a wedge surface; and an auxiliary member provided on the mounting block; the auxiliary member comprises an auxiliary block, a third wedge, a guide groove opened on the first wedge, a cavity opened in the mounting block, and a limiting groove opened on the wedge surface; the auxiliary block is in sliding connection with the guide groove, and the limiting groove is located on the movement track of the auxiliary block; the cavity is in communication with the linkage groove and the guide groove, respectively; the third wedge is in sliding connection with the cavity, the third wedge is fixedly connected with the auxiliary block, and the third wedge is located on the movement track of the wedge surface.

[0021] During the period when the linkage block drives the wedge surface to slide into the linkage groove until the wedge surface contacts the third wedge block, the third wedge block can drive the auxiliary block to move towards the position close to the limiting groove. During the movement of the auxiliary block until the auxiliary block slides into the limiting groove, the auxiliary block stops moving. During the period when the auxiliary block stops moving, the reinforcing effect of the wedge surface groove on the first wedge block is enhanced, the fit degree of the first wedge block and the wedge surface groove is higher, 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 ensured, and the connection between the base and the bottom groove is more stable.

[0022] In summary, through the further reinforcement of the linkage block on the mounting block and the further reinforcement of the auxiliary block on the first wedge block, the reinforcing 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 the base is firmly fixed in the bottom groove without deviation and shaking.

[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 cavity, the hollow ring can extrude the hook which is moving, so that the hook swings. During the gradual swinging of the hook, the hook also contacts the outer wall of the hollow ring, until the hollow ring passes the free end of the hook, so that the free end of the hollow ring can contact the inner wall of the hollow ring. Through the above movement, during the period when the hook contacts the inner wall of the hollow ring, the linkage block and the third wedge block can be connected to form a whole, and then the connection between the linkage block and the third wedge block is more close, that is, the mounting block is further fixed, and the stability of the mounting block is improved.

[0026] During the movement of the second wedge block, the first rack moves synchronously.

[0052] Specific implementation process:

[0053] During the foundation construction of the jacket type fan, in order to avoid irrelevant personnel from entering or interfering, during this period, the base 2 is placed into the bottom groove, and then workers use a 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 surface groove 7. During the movement of the mounting blocks 4, the first wedge blocks 5 move synchronously, and stop moving after the first wedge blocks 5 pass through the mounting holes 41 and slide into the wedge surface groove 7. During the movement of the first wedge blocks 5, the base 2 can be connected with the wedge surface groove 7 to form an integral whole, so that the base 2 cannot shake left and right. That is, through the joint action of the first wedge blocks 5 and the mounting blocks 4, the base 2 can be preliminarily fixed, so as to prepare for further fixing of the mounting blocks 4.

[0054] During the period of sliding the mounting block 4 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, until the second wedge block 11 slides into the side groove 12, the second wedge block 11 stops moving. Through the cooperation between the second wedge block 11 and the side groove 12, further reinforcement to the base 2 from different directions is realized, the diversity of reinforcing the base 2 is increased, the reinforcing effect of the base 2 is enhanced, and the stability of the connection between the base 2 and the bottom groove is improved.

[0055] During the movement of the second wedge block 11, the first rack 33 moves synchronously. During the movement of the first rack 33, since the first rack 33 is engaged with the first gear 32, the first gear 32 rotates. During the rotation of the first gear 32, since the first gear 32 is engaged with the second rack, the second rack moves along the length direction of the sliding groove 10 to the position close to the mounting block 4.

[0056] During the movement of the second rack, the sliding block 8 moves synchronously. During the movement of the sliding block 8 to the position close to the mounting block 4, 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 extruded to deform, that is, the expansion block 9 can fill the expansion groove 45, at this time, the expansion block 9 and the mounting block 4 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 external environmental factors or human factors, and the fixing effect of the mounting block 4 on the base 2 is enhanced.

[0057] Through the above movement, under the action of the first wedge block 5, the first wedge block 5 is connected with the bottom groove to form an integral whole; under the action of the mounting block 4, the base 2 is connected with the bottom groove to form an integral 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, fast and efficient to install, and 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 moves synchronously. During the movement of the second rack, when the second rack is engaged 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, since the worm 39 is engaged with the worm wheel 40, the worm wheel 40 rotates. During the rotation of the worm wheel 40, the screw rod 13 rotates synchronously. During the rotation of the screw rod 13, the nut seat 15 can drive the positioning block 16 to move to the position close to the base 2.

[0059] During the movement of the positioning block 16 to the position close to the base 2 until the positioning block 16 abuts against the base 2, the positioning block 16 stops moving. During the movement of the positioning block 16, the positioning block 16 can press the base 2, so that the base 2 is more closely attached to the bottom groove. That is, the connection between the base 2 and the bottom groove is more stable and firm, which further enhances the fixing effect of the base 2.

[0060] In summary, 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 and will not shake or deviate, which comprehensively enhances the reinforcement effect of the base 2 and ensures 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 the position close to the second electrode sheet 20. During the movement of the first electrode sheet 19, the first electrode sheet 19 contacts and is electrified with the second electrode sheet 20, so that the warning light 21 emits green light. After the warning light 21 emits green light, on the one hand, it can prompt the worker 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 directly and accurately helps the worker 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 whole, 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 continuous emission of green light by the warning light 21, it can ensure that the base 2 is always firmly connected with the bottom groove and does not loosen. If the green light is no longer emitted, it prompts the worker to timely reinforce the base 2, eliminating the safety hazard 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 it slides into the linkage groove 24. During the period when the linkage block 22 is located in the linkage groove 24, the linkage block 22 can further reinforce the mounting block 4, so that the connection between the mounting block 4 and the base 2 is more comprehensive and complete, that is, the stability of the mounting block 4 is improved, and the mounting block 4 will not shake due to changes in external environmental factors or human factors, so that the base 2 can be firmly fixed under the action of the mounting block 4.

[0063] During the period when 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, the third wedge block 27 can drive the auxiliary block 26 to move close to the position where the limiting groove 30 is located. During the movement of the auxiliary block 26, the auxiliary block 26 stops moving until the auxiliary block 26 slides into the limiting groove 30. During the period when the auxiliary block 26 stops moving, the reinforcing effect of the wedge surface groove 7 on the first wedge block 5 is enhanced, the fit degree of the first wedge block 5 and the wedge surface groove 7 is higher, 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 ensured, and the connection between the base 2 and the bottom groove is more stable.

[0064] In summary, through the further reinforcement of the linkage block 22 on the mounting block 4 and the further reinforcement of the auxiliary block 26 on the first wedge block 5, the reinforcing effect of the mounting block 4 and the first wedge block 5 on the base 2 is comprehensively enhanced, the stability during the connection between the base 2 and the bottom groove is improved, and the base 2 is firmly fixed in the bottom groove and cannot be deviated or shaken.

[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 cavity 29, the hollow ring 44 can extrude the hook 43 which is moving, so that the hook 43 swings. During the gradual swinging of the hook 43, the hook 43 also contacts the outer wall of the hollow ring 44, until the hollow ring 44 passes the free end of the hook 43, so that the free end of the hollow ring 44 can contact the inner wall of the hollow ring 44. Through the above movement, during the period when the hook 43 contacts the inner wall of the hollow ring 44, the linkage block 22 and the third wedge block 27 can be connected to form an integral whole, and then the connection between the linkage block 22 and the third wedge block 27 is more close, that is, the mounting block 4 is further fixed, and the mounting block 4 can be firmly fixed in the mounting hole 41, and the stability of the mounting block 4 is improved.
