Description

Technical Field

[0001] This utility model belongs to the field of anchor bolt installation technology, and in particular relates to a tool for lifting wind turbine anchor bolts. Background Technology

[0002] The wind power project requires the installation of several wind turbines, and each wind turbine requires the installation of a large number of anchor bolts. Since the installation progress of anchor bolts is directly related to the overall progress of the wind turbine foundation construction, and this process has strict quality requirements, the anchor bolts must be undamaged throughout the installation process. At the same time, the project has strict control over on-site process standards. In order to balance the quality and progress of anchor bolt installation, the project team needs to use anchor bolt lifting tools to ensure the orderly progress of construction.

[0003] For example, Chinese patent CN216859559U discloses a tool for installing anchor bolts, including: a lifting rod for transmitting lifting force; and a hook segment fixed to the bottom of the lifting rod, which, when engaged with the threaded section of the prestressed anchor bolt, presents a horizontal state when pulled upwards. Because the hook segment presents a horizontal state with the threaded section of the prestressed anchor bolt after engagement, when the prestressed anchor bolt is pulled upwards by the lifting rod, the hook segment of the lifting hook will be in contact with the outer diameter section of the threaded section of the prestressed anchor bolt in a horizontal state. Even if excessive force is applied or the prestressed anchor bolt undergoes slight positional changes, the hook segment of the lifting hook will not tilt or slide, damaging the outer diameter section of the threaded section, thus avoiding thread failure during installation of the prestressed anchor bolt.

[0004] However, the aforementioned lifting rod and hook section are fixedly connected, resulting in a fixed force angle and poor adaptability. At the same time, the lifting rod adopts an integrated fixed length design, which cannot be flexibly adjusted according to the differences in the operator's body size. This leads to increased effort in lifting operations, and long-term construction can easily cause fatigue in the back and arm muscles, reducing the overall installation efficiency.

[0005] To address these issues, we provide a tool for lifting wind turbine anchor bolts. Utility Model Content

[0006] The purpose of this utility model is to provide a tool for lifting wind turbine anchor bolts. By setting a fan-shaped plate and a U-shaped seat to cooperate with the positioning screw hole and the positioning bolt angle adjustment structure, and an inner rod and an L-shaped sleeve to cooperate with the adjustment hole and the spring pin length adjustment structure, it solves the problem that the existing wind turbine anchor bolt lifting tools have a fixed force angle and cannot adjust the lifting length, which makes it difficult to operate when adapting to operators of different body types.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a tool for lifting fan anchor bolts, including a hook and a semi-circular ring adapted to the anchor bolt, with a connecting rod fixedly connected to the middle of the outer edge of the semi-circular ring;

[0009] The connecting part includes a sleeve that is fixedly fitted to the outside of the connecting rod by bolts, a sector plate is fixedly connected to the top of the sleeve, and a U-shaped seat is rotatably connected to the outside of the sector plate;

[0010] The lifting part includes an inner rod that is detachably fixed to the top of the U-shaped seat, and an L-shaped sleeve is movably sleeved on the outside of the inner rod.

[0011] The present invention is further configured such that the inside of the sector plate is provided with a plurality of positioning screw holes equidistantly distributed along the arc edge, and the inside of the U-shaped seat is rotatably connected with a transversely penetrating positioning bolt, and the positioning bolt is threaded into the inside of the corresponding positioning screw hole.

[0012] The present invention is further configured such that a connecting column is fixedly connected to the top of the U-shaped seat, and the inner rod is fixedly sleeved to the outside of the connecting column by bolts.

[0013] The present invention is further configured such that the two ends of the semicircular ring are respectively provided with insertion holes and insertion blocks adapted to the insertion holes.

[0014] The present invention is further configured such that multiple adjustment holes are equidistantly provided inside the inner rod along the axial direction, and two symmetrical spring pins are fixedly connected to the outside of the L sleeve, and the spring pins are movably inserted into the corresponding adjustment holes.

[0015] The present invention is further provided that an anti-slip sleeve is fixedly sleeved on the outside of the short side of the L-sleeve.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model utilizes a rotating connection structure between a fan-shaped plate and a U-shaped seat, along with multiple equidistant positioning screw holes along the arc edge and a transversely penetrating positioning bolt. This allows for flexible adjustment of the lifting section's force angle, enabling operators of different body types to find an angle that suits their own force application habits, resulting in more natural and smooth force application and reduced operating effort. Simultaneously, the multi-position adjustment holes equidistantly opened along the axis on the inner rod and the spring pin on the outside of the L-shaped sleeve allow for convenient adjustment of the overall length of the lifting section, adapting to the grip distance requirements of operators of different body types. This avoids excessive extension or bending of limbs due to unsuitable length, further reducing the force burden and making operation more effortless.

[0018] 2. This utility model uses insertion holes and matching plugs at both ends of the semicircular rings to close and fix the two semicircular rings by inserting the plugs into the insertion holes, thereby forming a wrap-around fixing structure for the anchor bolt. This structure facilitates collaborative work by two operators, allowing each person to hold the corresponding part of the tool and apply lifting force to the anchor bolt simultaneously, effectively dispersing the workload required by a single operator and making the anchor bolt lifting operation more labor-saving.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1 to 5 This utility model is a tool for lifting wind turbine anchor bolts, including a hook 100 and a semi-circular ring 101 adapted to the anchor bolt. A connecting rod 102 is fixedly connected to the middle of the outer edge of the semi-circular ring 101. The design of the semi-circular ring 101 adapted to the anchor bolt can ensure that the hook 100 accurately hooks the anchor bolt.

[0029] The connecting part 200 includes a sleeve 201 that is fixedly sleeved to the outside of the connecting rod 102 by bolts. A sector plate 202 is fixedly connected to the top of the sleeve 201, and a U-shaped seat 203 is rotatably connected to the outside of the sector plate 202. The sleeve 201 is fixedly sleeved to the connecting rod 102 by bolts, which facilitates the disassembly and replacement of the sleeve 201 according to the diameter of the anchor bolt, thereby enhancing versatility. The sector plate 202 and the U-shaped seat 203 are rotatably connected, which can flexibly adjust the angle of the lifting part 300 to adapt to the lifting needs in different directions and improve the flexibility of tool use.

[0030] The lifting part 300 includes an inner rod 301 detachably fixed to the top of the U-shaped seat 203. An L-shaped sleeve 302 is movably sleeved on the outside of the inner rod 301. The inner rod 301 and the U-shaped seat 203 are detachably fixed, which facilitates the replacement of the inner rod 301 or other parts of the lifting part 300, reducing maintenance costs. The L-shaped sleeve 302 is movably sleeved on the inner rod 301, and the position of the L-shaped sleeve 302 on the inner rod 301 can be adjusted according to the lifting height requirements, making it more labor-saving and convenient for operators to use.

[0031] Specifically, the inside of the sector plate 202 is provided with multiple positioning screw holes 202a that are equidistantly distributed along the arc edge. The inside of the U-shaped seat 203 is rotatably connected with a transversely penetrating positioning bolt 205, and the positioning bolt 205 is threaded into the inside of the corresponding positioning screw hole 202a. The multiple positioning screw holes 202a that are equidistantly distributed along the arc edge, together with the threaded positioning bolt 205, can fix the rotation angle of the sector plate 202 and the U-shaped seat 203, thereby improving the stability of operation.

[0032] The inner rod 301 has multiple adjusting holes 301a equidistantly arranged along the axial direction inside. The L-sleeve 302 is externally fixedly connected to two symmetrical spring pins 302a, and the spring pins 302a are movably inserted into the corresponding adjusting holes 301a. The adjusting holes 301a equidistantly distributed along the axial direction provide multiple length adjustment options for the L-sleeve 302 to meet different lifting height requirements. The symmetrically arranged spring pins 302a can be quickly inserted into and fixed to the adjusting holes 301a, which is convenient to operate and firmly fixed, preventing the L-sleeve 302 from sliding during the lifting process.

[0033] Furthermore, a connecting post 204 is fixedly connected to the top of the U-shaped seat 203, and the inner rod 301 is fixedly sleeved to the outside of the connecting post 204 by bolts. The connecting post 204 is configured to provide transition support for the connection between the inner rod 301 and the U-shaped seat 203, increase the contact area, and improve the connection stability. The bolt-fixed sleeve method not only ensures the connection strength between the inner rod 301 and the connecting post 204, but also facilitates disassembly and maintenance, and reduces the difficulty of component replacement.

[0034] An anti-slip sleeve 303 is fixedly fitted to the short side of the L-sleeve 302. The anti-slip sleeve 303 can increase the friction between the hand and the L-sleeve 302, prevent the hand from slipping when lifting, ensure a stable grip, and improve the safety and comfort of operation.

[0035] The operation process of this embodiment is as follows: When it is necessary to install wind turbine anchor bolts, firstly, select a suitable hook 100 according to the diameter of the anchor bolt to be installed, and fix the sleeve 201 of the connecting part 200 to the outside of the connecting rod 102 of the hook 100 with bolts to complete the assembly of the hook 100 and the connecting part 200; then, according to the lifting direction requirements of the work site, rotate the U-shaped seat 203 to adjust it to a suitable angle relative to the sector plate 202, and then pass the positioning bolt 205 through the U-shaped seat 203 and screw it into the positioning screw hole 202a at the corresponding position on the sector plate 202 to fix the angle between the sector plate 202 and the U-shaped seat 203; then, fix the inner rod 301 of the lifting part 300 to the outside of the connecting post 204 at the top of the U-shaped seat 203 with bolts to complete the lifting part assembly. The connection between the L-sleeve 300 and the connecting part 200 is then established. Based on the actual lifting height requirements, the spring pin 302a on the outside of the L-sleeve 302 is moved to disengage it from the current adjustment hole 301a on the inner rod 301. Subsequently, the L-sleeve 302 is pushed to move along the axis of the inner rod 301 to a suitable position, and then the spring pin 302a is released, allowing it to automatically spring into the corresponding adjustment hole 301a on the inner rod 301 to fix the length of the lifting part 300. Afterward, the operator holds the anti-slip sleeve 303 on the outside of the short side of the L-sleeve 302, puts the semi-circular ring 101 of the hook part 100 into it and hooks the wind turbine anchor bolt to be installed. Then, the L-sleeve 302 is lifted upward, which drives the inner rod 301, U-shaped seat 203, sector plate 202, sleeve seat 201 and connecting rod 102 to work together to complete the lifting and installation operation of the anchor bolt.

[0036] Example 2

[0037] Please see Figure 2 and Figure 4 Based on the first specific embodiment, the two ends of the semi-circular ring 101 are respectively provided with a socket 103 and a plug 104 adapted to the socket 103.

[0038] The operation process of this embodiment is as follows: the matching design of the insertion hole 103 and the insertion block 104 allows the two semicircular rings 101 to be inserted into the insertion hole 103 through the insertion block 104 to achieve closure and fixation, thereby wrapping the anchor bolt. This allows two workers to work at the same time, making the operation more labor-saving.
