Description

Technical Field

[0001] The present application relates to the technical field of construction equipment, and in particular to a storage rack for finished threaded steel bars used in the construction of wind power tower foundations. Background Art

[0002] In the construction of wind turbine tower concrete foundation, cast-in-place construction is usually adopted. The steel bars used in the concrete foundation are basically processed in the steel bar processing workshop, that is, the steel bars are cut and processed into finished steel bars, and the finished steel bars are transported to the construction site.

[0003] Since the finished steel bars are processed in batches, they are stacked or placed on steel bar storage racks, which are generally welded from steel sections. When the finished steel bars are transported, they need to be taken off the storage racks and hoisted onto a transport vehicle, and then transported to the wind turbine tower concrete construction site for unloading.

[0004] During the storage and transportation process, the finished steel bars need to be taken and placed many times. On the one hand, the transfer and transportation of the steel bars is rather cumbersome and inconvenient. On the other hand, the steel bars are prone to collision during this process. Since the ends of the steel bars are relatively sharp, it is easy to cause economic losses. Summary of the invention

[0005] The present application provides a storage rack for finished threaded steel bars used in the construction of wind turbine tower foundations, which is convenient for the storage, lifting, transfer and transportation of finished steel bars, and adopts the following technical solutions:

[0006] A storage rack for finished threaded steel bars used in wind power tower foundation construction, comprising a base frame, a first side frame and a second side frame, wherein the first side frame and the second side frame are both hinged to the base frame, and a steel bar placement area is provided between the base frame, the first side frame and the second side frame;

[0007] It also includes a connecting mechanism, which includes a fixing hook and a connecting piece; the fixing hook is fixedly connected to the first side frame, and the connecting piece is rotatably arranged on the second side frame and can be hooked with the fixing hook;

[0008] It also includes a hanging ring, which is arranged on the first side frame or the second side frame.

[0009] By adopting the above technical solution, the first side frame and the second side frame are hinged on the base frame, which makes it convenient to place the finished steel bars into the steel bar placement area. When the storage rack needs to be lifted, the connecting piece is rotated to connect it with the fixed hook, thereby stably connecting the first side frame and the second side frame. The hook of the lifting equipment is connected to the lifting ring, so that the entire storage rack can be lifted and moved. The operation is simple and convenient, which improves construction efficiency.

[0010] Preferably, the connecting member comprises a suspension rod, one end of which is rotatably connected to the second side frame, and the other end of which is snap-fitted with a fixed hook; the suspension ring is fixedly connected to the suspension rod.

[0011] By adopting the above technical solution, one end of the suspension rod is rotatably connected to the second side frame, and the other end is engaged with the fixed hook. When the storage rack needs to be lifted, the suspension rod is engaged with the fixed hook, and the lifting ring is fixedly connected to the suspension rod. Then, the entire storage rack is lifted and moved by the lifting equipment. The operation is simple and convenient, which improves the construction efficiency.

[0012] Preferably, the connecting member also includes a limit frame, which is spaced apart from the suspension rod and fixedly connected via a connecting plate; when the fixing hook is connected to the suspension rod, the limit frame can be rotated to the outside of the fixing hook and limit the fixing hook; the lifting ring and the limit frame are arranged on the same side of the suspension rod.

[0013] By adopting the above technical solution, the setting of the limit frame increases the stability of the connection between the boom and the fixed hook, making it difficult for the boom to separate from the fixed hook, thereby increasing the safety of the hoisting process. At the same time, since the lifting ring and the limit frame are set on the same side of the boom, the lifting ring will always be located above the boom during hoisting, so that the limit frame will always be located above the fixed hook, ensuring the limiting effect on the fixed hook, thereby ensuring that the fixed hook will not separate from the boom, thereby improving safety.

[0014] Preferably, the first side frame comprises a first pillar, one end of which is rotatably connected to the bottom frame, and the other end of which is connected to a fixing hook; the second side frame comprises a second pillar, one end of which is rotatably connected to the bottom frame, and the other end of which is connected to a suspension rod;

[0015] When the suspension rod is matched with the fixing hook, the suspension ring is located between the first support column and the second support column; a limit stopper is also provided at one end of the suspension rod connected with the fixing hook.

[0016] By adopting the above technical solution, the lifting ring is located between the first support and the second support, so that the weight is evenly distributed on both sides of the lifting ring, ensuring the stability of the lifting process. The limit baffle limits the position of the fixed hook, thereby increasing the stability of the connection between the lifting rod and the fixed hook, making it difficult for the lifting rod to separate from the fixed hook, thereby increasing the safety of the lifting process.

[0017] Preferably, the base frame comprises a support frame, and connecting rods are provided on both sides of the support frame, and the connecting rods are fixedly connected to the support frame; the first pillar and the second pillar are both rotatably connected to the connecting rods.

[0018] By adopting the above technical solution, the setting of the connecting rod facilitates the rotational connection between the first support and the second support and the base frame, thereby facilitating the opening and closing of the storage rack.

[0019] Preferably, support plates are provided on the bottom sides of the first pillar and the second pillar, and the support plates are used to abut against the ground, so that the first pillar and the second pillar remain in a standing state.

[0020] By adopting the above technical solution, the setting of the support plate increases the contact area between the first pillar and the second pillar and the ground, so that the first pillar and the second pillar can maintain a standing state more stably, thereby allowing the storage rack to be placed on the ground more stably.

[0021] Preferably, the base frame further comprises a guide rod, which is arranged in a direction from the first side frame to the second side frame, and both ends of the guide rod are fixedly connected to the support frame; the guide rod comprises a first part close to the first side frame and a second part close to the second side frame; the first side frame is provided with a first support rod, and the second side frame is provided with a second support rod.

[0022] One end of the first support rod is slidably connected to the second part, and the other end is rotatably connected to the first side frame; one end of the second support rod is slidably connected to the first part, and the other end is rotatably connected to the second side frame;

[0023] When the first side frame and the second side frame are in a closed state, the ends of the first support rod and the second support rod are both in contact with the support frame and in a crossed state, thereby supporting the first side frame and the second side frame.

[0024] By adopting the above technical solution, when the first side frame and the second side frame rotate to a closed state, the first support rod and the second support rod slide with the rotation of the first side frame and the second side frame. When the first side frame and the second side frame are closed, the first support rod and the second support rod cross and support the first side frame and the second side frame, thereby increasing the overall stability of the storage rack.

[0025] Preferably, a storage groove is provided on the inner side of the base frame, and the first support column and the second support column can be rotated into the storage groove.

[0026] By adopting the above technical solution, the setting of the storage slot makes it convenient to fold up the first support and the second support when the storage rack is not in use, thereby reducing the space occupied by the storage rack and facilitating the storage and transportation of the storage rack.

[0027] Preferably, the first side frame and the second side frame are further provided with a retaining frame, and the retaining frame is provided with a plurality of grooves, and the grooves can cooperate with the finished steel bars to retain the finished steel bars.

[0028] By adopting the above technical solution, the setting of the retaining frame can limit the finished steel bars placed in the steel bar placement area, preventing the finished steel bars from rolling or sliding during storage and transportation, thereby improving the safety of construction.

[0029] In summary, the present invention includes at least one of the following beneficial technical effects:

[0030] 1. Since the present invention adopts a hinged first side frame and a second side frame, which can rotate on the bottom frame, the finished steel bars can be conveniently placed in the steel bar placement area. At the same time, by providing a connecting mechanism and a lifting ring, the present invention can conveniently connect the first side frame and the second side frame, and easily lift the entire storage rack through a lifting device, which not only simplifies the construction process, but also enhances the safety of operation;

[0031] 2. The design of the limit frame, limit baffle, support plate, retaining frame and other structures further enhances the stability and safety of the storage rack, ensuring that the finished steel bars will not roll, slide or collide during storage and transportation, effectively reducing economic losses and safety hazards;

[0032] 3. The design of the storage slot fully considers the practicality and convenience of the storage rack, so that it can be easily stored when not in use to save space. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1 —4 The present invention is described in further detail.

[0039] This embodiment discloses a storage rack for finished threaded steel bars used in wind power tower foundation construction, referring to Figure 1 and Figure 2 , which mainly includes a base frame 1, a first side frame 2 and a second side frame 3. The base frame 1 serves as the foundation of the entire storage rack and bears the weight of other components and finished steel bars. The first side frame 2 and the second side frame 3 are both hinged to the base frame 1, so that the side frames can rotate freely on the base frame 1, which is convenient for storing and taking out finished steel bars. When the side frames are closed, a steel bar placement area is enclosed between the base frame 1, the first side frame 2 and the second side frame 3 for storing finished steel bars.

[0040] In addition, the storage rack further includes a connecting mechanism 4 and a lifting ring 5. The connecting mechanism 4 is composed of a fixing hook 41 and a connecting piece, wherein the fixing hook 41 is fixed on the first side frame 2, and the connecting piece can be rotatably arranged on the second side frame 3. When the storage rack needs to be closed, it is only necessary to hook the connecting piece and the fixing hook 41. The lifting ring 5 is arranged on the first side frame 2 or the second side frame 3, and is used to connect with the hook of the lifting equipment, so as to lift the entire storage rack for transfer or transportation.

[0041] The storage, transfer and transportation of finished steel bars are simplified and convenient by the design of the first side frame 2 and the second side frame 3 hinged to the base frame 1, the connection mechanism 4 and the lifting ring 5. At the same time, since the entire storage rack can be conveniently hoisted by hoisting equipment, the construction efficiency and safety are greatly improved.

[0042] In the embodiment of the present application, the base frame 1 specifically includes a support frame 11 and a connecting rod, and the connecting rod is provided with two groups and is respectively located on both sides of the support frame 11. The first side frame 2 and the second side frame 3 are both connected to the base frame 1 through the connecting rod, and the first side frame 2 and the second side frame 3 are both rotatably connected to the connecting rod, so that the side frames can rotate freely on the base frame 1.

[0043] The first side frame 2 specifically includes a plurality of first pillars 21, which are arranged along the length direction of the base frame 1. One end of the first pillar 21 is rotatably connected to the connecting rod, and the other end extends to the upper side of the base frame 1. The plurality of first pillars 21 are connected to each other through a fixing rod. The second side frame 3 specifically includes a plurality of second pillars 31, which are arranged along the length direction of the base frame 1. One end of the first pillar 21 is rotatably connected to the connecting rod, and the other end extends to the upper side of the base frame 1. The plurality of first pillars 21 are also connected to each other through a fixing rod.

[0044] Reference Figure 1 and Figure 3Furthermore, the fixing hook 41 is fixedly connected to the end of the second pillar 31, and the connecting member includes a suspension rod 42, one end of which is rotatably connected to the second pillar 31, and the other end can be inserted into the hook groove of the fixing hook 41, so as to realize the connection between the suspension rod 42 and the fixing hook 41. The lifting ring 5 is fixedly connected to the middle position of the suspension rod 42. When the first pillar 21 and the second pillar 31 rotate relatively, and the suspension rod 42 is connected to the fixing hook 41, the lifting ring 5 is located between the first pillar 21 and the second pillar 31, so that the load of the storage rack is dispersed on both sides of the lifting ring 5 through the first pillar 21 and the second pillar 31, thereby improving the stability of the lifting process.

[0045] As a preferred implementation of the embodiment of the present application, the connecting piece can also be arranged in an annular shape as a whole, and is rotatably connected to the first pillar 21, and the connecting piece can be directly hooked with the fixing hook 41, thereby completing the connection between the two. The lifting ring 5 is arranged on the upper side of the connecting piece and is fixedly connected to the connecting piece.

[0046] Reference Figure 3 A limit baffle 43 is also fixed to the end of the suspension rod 42 away from the first pillar 21. The limit baffle 43 limits the position of the fixing hook 41, thereby increasing the stability of the connection between the suspension rod 42 and the fixing hook 41, making it difficult for the suspension rod 42 to separate from the fixing hook 41, thereby increasing the safety of the lifting process.

[0047] Furthermore, the connecting member further includes a limiting frame 44, which is spaced apart from the suspension rod 42 and fixedly connected via a connecting plate. In the embodiment of the present application, the connecting plate may be a limiting baffle 43, that is, one end of the suspension rod 42 is fixedly connected to the lifting ring 5, and the other end is fixedly connected to the limiting baffle 43. When the fixing hook 41 is connected to the suspension rod 42, the limiting frame 44 can be rotated to the outside of the fixing hook 41 and limit it, which can ensure that the fixing hook 41 will not be separated from the suspension rod 42, thereby enhancing the stability and safety of the storage rack during the lifting process.

[0048] At the same time, the lifting ring 5 and the limiting frame 44 are arranged on the same side of the lifting rod 42. During lifting, the lifting ring 5 is connected to the lifting equipment and is therefore always located above the lifting rod 42. Therefore, the limiting frame 44 is also always located above the fixing hook 41, thereby ensuring the limiting effect on the fixing hook 41 and improving safety.

[0049] The bottom sides of the first pillar 21 and the second pillar 31 are both provided with a support plate 6, and the support plate 6 is used to abut against the ground, so that the first pillar 21 and the second pillar 31 can maintain a standing state, thereby allowing the storage rack to be placed on the ground more stably.

[0050] Reference Figure 4In order to further enhance the functionality and practicality of the storage rack, a retaining frame 7 is further provided on the first side frame 2 and the second side frame 3. The retaining frame 7 is fixedly connected to the side frame and has a plurality of grooves thereon. These grooves can cooperate with the finished steel bars, thereby retaining the finished steel bars and preventing the steel bars from rolling or sliding during storage and transportation. This design not only improves the construction efficiency, but also reduces economic losses and safety hazards. At the same time, the entire storage rack is made of steel, which has high strength and durability, can withstand large weight and pressure, and further ensures the safety and reliability of the construction.

[0051] Optionally, the first pillar 21 and the second pillar 31 are both bent toward the outside of the steel bar placement area, thereby increasing the volume of the steel bar placement area to facilitate storage of more finished steel bars.

[0052] Reference Figure 1 , Figure 2 and Figure 4 In order to further improve the stability of the first support column 21 and the second support column 31 , the base frame 1 further includes a guide rod 12 , a first support rod 13 and a second support rod 14 .

[0053] Specifically, the guide rod 12 is arranged along the width direction of the support frame 11, that is, along the direction from the first pillar 21 to the second pillar 31, and both ends of the guide rod 12 are fixedly connected to the support frame 11. The guide rod 12 is divided into a first part close to the first pillar 21 and a second part close to the second pillar 31.

[0054] One end of the first support rod 13 is slidably connected to the second part through the first slider 15, and the other end is rotatably connected to the first side frame 2. One end of the second support rod 14 is slidably connected to the first part through the second slider 16, and the other end is rotatably connected to the second side frame 3.

[0055] Therefore, refer to Figure 4 When the first side frame 2 and the second side frame 3 are in a closed state, the ends of the first support rod 13 and the second support rod 14 are in contact with the support frame 11 and are in a crossed state, thereby supporting the first side frame 2 and the second side frame 3.

[0056] When the first side frame 2 and the second side frame 3 are in the open state, the first sliding block 15 and the second sliding block 16 abut against each other, thereby supporting the first side frame 2 and the second side frame 3 and ensuring the stability of the first side frame 2 and the second side frame 3 .

[0057] When the first side frame 2 and the second side frame 3 are in an open state, the first support rod 13 and the second support rod 14 can support them respectively to ensure their stability; during lifting, the first support rod 13 and the second support rod 14 can strengthen the first side frame 2 and the second side frame 3 so that they can bear a larger weight and are not easily deformed.

[0058] In addition, a storage slot can be selectively provided inside the support frame 11, and the first support column 21 and the second support column 31 can be rotated into the storage slot, so that the first side frame 2 or the second side frame 3 can be stored inside the support frame 11 when not in use, and multiple storage racks can be stacked together, thereby saving storage space for the storage racks. In order to allow the first side frame 2 and the second side frame 3 to be stored normally, it is necessary to cancel the connection between the first support rod 13 and the second support rod 14 and the first support column 21 and the second support column 31, so as to ensure that the first side frame 2 and the second side frame 3 have sufficient rotation space.

[0059] The implementation principle of the embodiment of the present application is: the first side frame 2 and the second side frame 3 are in an open state, and the finished steel bars can be stored in the steel bar placement area. When the steel bars need to be transported, the first side frame 2 and the second side frame 3 are rotated, and the first side frame 2 and the second side frame 3 are connected through the connecting mechanism 4, and the storage rack can be hoisted as a whole and transferred to the transport vehicle through the lifting equipment and the lifting ring 5, and the subsequent transportation is completed, so that the transfer and transportation of the finished steel bars is efficient, convenient, safe and reliable.

[0060] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
