Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building engineering construction equipment design, relates to the technical field of concrete pouring auxiliary equipment design, and specifically relates to a reinforcing cage hoisting device. BACKGROUND

[0002] The production of prefabricated concrete segments usually involves pouring concrete into a mold, and the concrete is solidified with a reinforcing cage to form the required segment. Due to the relatively large overall size of the prefabricated concrete segments, the size of the reinforcing cage also increases. The oversized reinforcing cage encounters many difficulties during transportation.

[0003] To solve this problem, an automatic bridge crane is usually used for lifting work. Since the reinforcing cage is composed of many interlaced steel bars, the complex structure makes it difficult for conventional lifting claws to effectively grasp and adjust the position of the reinforcing cage, increasing the complexity and difficulty of operation. During lifting, the weight and volume of the oversized reinforcing cage increase significantly, which not only puts higher requirements on the transportation equipment, but also poses higher challenges to the technical level of the operators. In actual operation, due to the complex structure of the reinforcing cage, conventional lifting claws often have difficulty finding suitable gripping points, making lifting work extremely difficult. In addition, the variety of shapes and sizes of reinforcing cages also increases the adaptability requirements of lifting equipment, requiring operators to have higher flexibility and adaptability.

[0004] Chinese patent application CN220033750U discloses a buckle structure for hoisting reinforcing cage, which mainly improves the safety of reinforcing cage during hoisting by positioning and locking the reinforcing cage through multiple connection mechanisms. This technology ensures the stability and reliability of the reinforcing cage during hoisting, effectively avoiding dangerous situations such as displacement, tilting or overturning of the reinforcing cage during hoisting. In addition, adjustment mechanisms, handles, arc-shaped openings and rubber pads are also designed as auxiliary devices. The main function of these devices is to adjust the length of the second wire rope. Through these adjustment devices, the length of the wire rope can be flexibly adjusted according to actual needs, thereby adapting to the hoisting needs of reinforcing cages of different sizes. In this way, regardless of the size of the reinforcing cage, the safety of the hoisting process can be ensured by adjusting these devices.

[0005] However, the above patent application adopts the way of setting buckles to directly carry out the hoisting operation of the reinforcement cage. Since each component of the reinforcement cage is mainly composed of cylindrical steel bars, when the size of the reinforcement cage is large and the weight is heavy, the buckles are prone to slipping. In addition, during the hoisting process, the center of gravity of the reinforcement cage is often unstable, which will cause it to sway in the air, so that the tension of the hoisting cable is larger, increasing the difficulty and danger of the hoisting operation. SUMMARY

[0006] The utility model embodiment provides a reinforcement cage hoisting device to solve the problem of unstable center of gravity when hoisting the reinforcement cage in the prior art.

[0007] The utility model discloses a reinforcement cage hoisting device through the following technical scheme:

[0008] A reinforcement cage hoisting device is characterized by comprising an installation part, a first clamping part and a second clamping part.

[0009] The installation part is used for being connected with a hoisting device and is a plane hoisting connection support plate. The lower surface of the support plate is symmetrically provided with a first clamping part and a second clamping part. The first clamping part and the second clamping part form a clamping cavity. When the hoisting device is clamped, the reinforcement cage is located in the clamping cavity. The first clamping part and the second clamping part are driven to realize the hoisting of the reinforcement cage.

[0010] The first clamping part and the second clamping part are both composed of an opening and closing mechanism and a reinforcement cage grabbing mechanism. The opening and closing mechanism comprises a clamping arm driven to rotate around a shaft to realize opening and closing by a driving cylinder. The end of the clamping arm is provided with the reinforcement cage grabbing mechanism. The reinforcement cage grabbing mechanism comprises a mounting rod horizontally arranged on the end of the clamping arm and a plurality of clamping teeth arranged in the lower part of the mounting rod. The clamping teeth are rod-shaped structures. One end of the rod-shaped structure is arc-shaped and detachably fixed to the mounting rod. The other end of the rod-shaped structure is a straight rod. The plurality of clamping teeth are arranged in parallel and perpendicularly to the mounting rod. The clamping teeth of the first clamping part and the clamping teeth of the second clamping part are oppositely and staggeringly arranged.

[0011] Further, two suspension hoisting plates are fixedly arranged on the lower surface of the support plate of the installation part in parallel. The opening and closing mechanism of each clamping part comprises two clamping arms arranged in parallel. One of the clamping arms is a driving clamping arm and the other is a driven clamping arm. The two clamping arms are fixed to the two ends of a rotating shaft. The rotating shaft is rotatably installed on the two suspension hoisting plates arranged in parallel after being sleeved with a bearing. The ends of the two clamping arms are connected and fixed with the horizontally arranged mounting rod. The extension arm above the connection position of the driving clamping arm and the rotating shaft is drivingly connected with the piston end of the driving cylinder to drive the clamping arm to rotate around the rotating shaft to realize opening and closing.

[0012] Further, the driving clamping arm and the driven clamping arm of the clamping arm are arranged on the outer side or the inner side of the two suspension hoisting plates.

[0013] Further, the driving clamping arms and the driven clamping arms of the clamping arms are arranged outside the two hanging plates, and the two sets of auxiliary clamping devices arranged symmetrically are arranged inside the two hanging plates; each set of the auxiliary clamping devices comprises two parallel clamping arms, one of which is a driving clamping arm and the other is a driven clamping arm, the two clamping arms are fixed at two ends of a sleeve, the sleeve is sleeved on a rotating shaft and arranged inside the two hanging plates, the two clamping arms are fixedly connected with a transversely arranged clamping rod at the ends, the driving clamping arm is drivingly connected with the piston end of the clamping cylinder above the connecting position of the driving clamping arm and the sleeve, and the driving clamping arm is driven to rotate around the rotating shaft to achieve auxiliary clamping and fixing of the reinforcement cage.

[0014] Further, the clamping arms and the clamping arms are in arc or curved structure, and the opposite clamping arms form a clamping structure of an inner circle when closed, and the opposite clamping arms form a clamping structure of an inner circle when closed.

[0015] Further, the clamping arms are detachably connected and fixed with the transversely arranged mounting rod through the mounting seat.

[0016] The reinforcement cage hoisting device has the following beneficial effects:

[0017] In the design of the utility model, through the rod-shaped clamping tooth structure, accurate adaptation with the reinforcement cage can be realized. The rod-shaped clamping teeth can be deeply inserted into the gaps of the reinforcement cage, so that a very stable clamping effect is realized. When the driving part starts to work and drives the first clamping part and the second clamping part to perform the clamping action, the rod-shaped clamping teeth will be further deeply inserted into the gaps of the reinforcement cage. With the clamping action, the rod-shaped clamping teeth will gradually penetrate, and finally the reinforcement cage will be firmly fixed in the clamping cavity, the position of the reinforcement cage is strictly limited, and the center of gravity is effectively limited in the clamping cavity, so that the reinforcement cage is prevented from swinging or shifting during the carrying or operation process. The hoisting device can realize stable clamping of the reinforcement cage, and ensure the safety and accuracy of the operation. BRIEF DESCRIPTION OF DRAWINGS

[0026] Embodiment 1

[0027] As Figure 1As shown in the figure, this embodiment of a rebar cage hoisting device, by setting up a clamping part and a matching clamping tooth 222 structure, can effectively achieve firm clamping and safe hoisting of the rebar cage. The device uses mechanical clamping teeth 222 to ensure that the clamping part can tightly fit against the surface of the rebar cage. Through the cooperation of the clamping teeth 222, a strong gripping force and a large clamping area are provided, thereby ensuring that the rebar cage will not slip or fall off during hoisting. The entire device has a compact structure, is easy to operate, and greatly improves the efficiency and safety of rebar cage hoisting operations.

[0028] like Figure 4 As shown, a mounting part 100 is provided at the top of the hoisting device for installation and hoisting. A first clamping part 110 and a second clamping part 120 are respectively provided at both ends of the mounting part 100. These two clamping parts are symmetrically distributed on both sides of the mounting part 100, ensuring overall balance and stability.

[0029] like Figure 1 As shown, a clamping cavity 130 is formed in the region between the first clamping part 110 and the second clamping part 120. The function of the clamping cavity 130 is to accommodate and secure the object being hoisted, such as a steel cage. When the first clamping part 110 and the second clamping part 120 perform a clamping action, the steel cage is clamped within the clamping cavity 130. Subsequently, through the coordinated work of these two clamping parts, a secure clamping of the steel cage can be achieved. This clamping action relies on a rotating shaft. The rotating shaft provides a basis for rotation, allowing the first clamping part 110 and the second clamping part 120 to rotate relative to each other, thereby realizing the clamping and releasing actions.

[0030] After the clamping teeth 222 are bent, they can penetrate deep into the interior of the reinforcing cage for clamping. The contact position between the clamping teeth 222 and the reinforcing cage is the clamping and receiving position 223.

[0031] like Figure 1 As shown, bearing seats 210 are provided at both ends of the first clamping part 110. The bearing seats 210 are configured to support and fix the first rotating shaft 111, allowing the first clamping part 110 to rotate flexibly. The first clamping part 110 is further equipped with a first clamping arm 112 and a second clamping arm 113 via the bearing seats 210 and the first rotating shaft 111 at both ends. These two clamping arms are located on both sides of the first rotating shaft 111, forming a symmetrical structure, enabling the clamping part to more effectively clamp and fix objects. The design of the first clamping arm 112 and the second clamping arm 113 not only increases the flexibility of the clamping part but also improves its operational accuracy and stability.

[0032] The first clamping arm 112 and the second clamping arm 113 are arranged with a certain arc, or in other words, are installed at a certain angle with the first rotating shaft 111. The purpose of this structure is to leave enough space to facilitate the clamping of the reinforcement cage. Generally, in order to better adapt to the shape and size of the reinforcement cage, the first clamping arm 112 and the second clamping arm 113 are arranged in a curved structure. This curved structure not only provides a larger clamping range, but also increases the strength and stability of the clamping arm, thereby ensuring the reliability and safety during clamping of the reinforcement cage. Through this structural arrangement, the first clamping part 110 can better adapt to various different working environments and needs, thereby improving the performance and efficiency of the overall equipment.

[0033] The second clamping part 120 is arranged and structured identically to the first clamping part 110, also including the third clamping arm 122 and the fourth clamping arm 123. At the end position of the first clamping part 110 and the second clamping part 120, rod-shaped clamping teeth 222 with a specific shape are provided. These clamping teeth 222 are curved inward, forming a specific position for clamping and receiving the reinforcement cage. In addition, a driving component is provided on the structure of the mounting seat 220, which functions to control and drive the movement of the first clamping part 110 and the second clamping part 120, thereby achieving the clamping or releasing operation of the reinforcement cage. This ensures the consistency and symmetry of the clamping part, and also improves the flexibility of operation and the efficiency of work.

[0034] At both ends of the second clamping part 120, bearing seats 210 are also provided, which enable the second clamping part 120 to be installed on the second rotating shaft 121 through the arrangement at both ends. Specifically, the second clamping part 120 can rotate on the second rotating shaft 121 through the bearing seats 210 at both ends.

[0035] At the same time, the first clamping arm 112 and the second clamping arm 113 are respectively arranged at the outer side positions of the two ends of the first rotating shaft 111. In order to ensure the stability and functionality of the structure, the first clamping arm 112 and the second clamping arm 113 are fixedly connected with the first rotating shaft 111. This design ensures that the first clamping arm 112 and the second clamping arm 113 can move synchronously with the rotation of the first rotating shaft 111.

[0036] Similarly, the third clamping arm 122 and the fourth clamping arm 123 are also respectively arranged at the outer side positions of the two ends of the second rotating shaft 121. In order to maintain the symmetry and balance of the overall structure, the third clamping arm 122 and the fourth clamping arm 123 are also fixedly connected with the second rotating shaft 121. This design enables the third clamping arm 122 and the fourth clamping arm 123 to move synchronously with the rotation of the second rotating shaft 121.

[0037] As shown in Figure 3 The driving component includes a first driving cylinder 310 for driving the first clamping part 110. The driving component also includes a second driving cylinder 320 for driving the second clamping part 120. In order to achieve the clamping function, the first clamping arm 112 of the first clamping part 110 is specially provided with a connecting rod articulated with the piston rod 311 of the first driving cylinder 310. Similarly, the third clamping arm 122 of the second clamping part 120 is also equipped with a connecting rod articulated with the piston rod 311 of the second driving cylinder 320. Through the design of these connecting rods, when the first driving cylinder 310 and the second driving cylinder 320 are driven, the first clamping part 110 and the second clamping part 120 can be correspondingly rotated based on the first rotating shaft 111 and the second rotating shaft 121. Specifically, by driving the first driving cylinder 310 and the second driving cylinder 320, through the extension or contraction action of the piston rod 311, the first clamping part 110 and the second clamping part 120 can be driven to achieve the clamping or releasing action.

[0038] In use, the first driving cylinder 310 and the second driving cylinder 320 need to be started at the same time. Through the articulation of the piston rod 311 with the connecting rods of the first clamping arm 112 and the third clamping arm 122, the connecting rods are pushed, thereby driving the first clamping part 110 and the second clamping part 120 to achieve the clamping or releasing action. Specifically, when the piston rod 311 extends outward, the connecting rods are pushed, so that the first clamping part 110 and the second clamping part 120 are clamped. At this time, the longer the piston rod 311 extends, the greater the clamping force will be. Conversely, when the piston rod 311 is retracted inward, the first clamping part 110 and the second clamping part 120 will be opened. When the piston rod 311 is completely retracted into the cylinder, the opening angle reaches the maximum, thereby achieving the completely released state.

[0039] In this embodiment, the end portions of the first clamping arm 112 and the second clamping arm 113 are provided with mounting seats 220. The arrangement of these mounting seats 220 enables the first clamping arm 112 and the second clamping arm 113 to be connected through their respective mounting rods 221. These mounting rods 221 are uniformly distributed with a plurality of clamping teeth 222, which are arranged at intervals on the mounting rod 221, ensuring that they can effectively clamp and fix objects.

[0040] In particular, the clamping teeth 222 and the mounting rod 221 are connected in a detachable manner. The advantage of this design is that the operator can easily replace mounting rods 221 of different lengths according to actual needs, thereby adapting to steel cages of different widths. This flexibility enables the clamping device to be widely used in steel cages of various sizes, improving the application range and work efficiency of the equipment.

[0041] In addition, by detachably connecting the mounting rod 221 and the mounting seat 220, the operator can also adjust according to the specific width of the reinforcement cage, increase or decrease the length of the clamping device. This design not only makes the clamping device can adapt to different width of reinforcement cage, also can set different interval of clamping teeth 222 according to the density of reinforcement in reinforcement cage. In this way, the clamping device can realize more accurate and stable clamping effect, also facilitate the transportation and handling work of reinforcement cage. Through this adjustable design, the clamping device can better meet the needs of various complex working conditions, improve the overall work efficiency and safety.

[0042] Embodiment 2

[0043] As shown in Figure 1 , Figure 2 , a reinforcement cage hoisting device of the present embodiment. In embodiment 1, by being able to disassemble or install the clamping teeth 222 according to the overall size of the reinforcement cage, the clamping adjustment function of different size reinforcement cage is realized. In general operation process, when the clamping size of the reinforcement cage is larger, a cavity will be formed between the first clamping part 110 and the second clamping part 120. Although this cavity will not affect the clamping or transportation of the reinforcement cage when clamping the larger size reinforcement cage, but when clamping the smaller size reinforcement cage, the situation is different. At this time, the reinforcement cage may sway during transportation, resulting in deviation from the cavity. Although this deviation will not cause the reinforcement cage to fall, but still will bring certain risk coefficient, and will have adverse effect on the service life of the clamping teeth 222.

[0044] As shown in Figure 2 , Figure 3 , in order to solve the above problems, a protection frame is specially set in the present embodiment. In the cavity formed by the first clamping part 110 and the second clamping part 120, a first protection frame 410 and a second protection frame 420 are respectively arranged. These protection frames are driven by the third driving cylinder 330 and the fourth driving cylinder 340. The first protection frame 410 and the second protection frame 420 are respectively hinged with the first rotating shaft 111 and the second rotating shaft 121, and rotate synchronously with the rotating shaft. In addition, the first protection frame 410 and the second protection frame 420 are respectively provided with a connecting structure hinged with the third driving cylinder 330 and the fourth driving cylinder 340, so that they can be driven by the driving cylinder. In this way, the protection frame can effectively protect the part of the reinforcement cage in the cavity, so as to avoid the reinforcement cage from deviating out of the cavity during transportation.

[0045] Further, the protection frame can also be provided with protection rods. These protection rods will abut the reinforcement cage during the clamping process, which can further ensure the stability of the reinforcement cage during transportation. This design not only improves the safety of the reinforcement cage hoisting device, but also prolongs the service life of the clamping teeth 222, ensuring the efficiency and safety of the entire hoisting process.
