Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a detachable rebar clamp based on a crane. Background Technology
[0002] In the construction process of building projects, the connection and fixing of steel bars is a crucial step. It requires selecting materials based on specific design requirements, connecting and fixing them during fabrication and processing, and then pouring concrete to form a reinforced concrete frame. Currently, the installation of steel bars mainly relies on manual labor on-site for short-distance transport, connection, and fixing. In large-scale building construction, large-diameter steel bars are frequently used due to their weight, and connecting and fixing even a single large-diameter steel bar requires significant manpower and a considerable amount of time.
[0003] In the process of steel reinforcement construction, detachable steel bar clamps based on cranes are required. A search revealed a patent document with publication number CN218434542U, which discloses a detachable steel bar clamp based on a crane. This clamp includes a lifting lug connector and a steel bar clamping component. The clamping component comprises a detachably connected first and second steel bar clamps, spaced apart to form a clamping cavity. The clamping cavity can surround the steel bar. The first steel bar clamp is rotatably connected to the lifting lug connector. When one end of the steel bar is equipped with a steel bar sleeve, the first and / or second steel bar clamps can prevent the steel bar sleeve from passing through the clamping cavity. This invention allows for the rapid completion of steel bar suspension, hole alignment, wire tightening, and fixing processes with the assistance of crane operators and a small number of workers.
[0004] However, the detachable rebar clamp based on a crane has problems such as insufficient clamping force and poor adaptability to rebars of different diameters when clamping rebars of different diameters. This causes the rebars to slip or be damaged during hoisting, which not only affects construction efficiency but also poses safety hazards and cannot meet the usage requirements. Therefore, a detachable rebar clamp based on a crane is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a detachable rebar clamp based on a crane, which has the advantages of stable clamping and high construction efficiency. It solves the problems of insufficient clamping force and poor adaptability to different diameter rebars when clamping rebars based on cranes, which leads to the rebars easily slipping or being damaged during hoisting, affecting construction efficiency and posing safety hazards, and failing to meet the usage requirements.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a detachable rebar clamp based on a crane, comprising a tension block, a clamping block disposed on the right side of the tension block, and a fixing block disposed on the right side of the clamping block, wherein a driving structure is disposed on the outside of the tension block, and a guide component is disposed on the outside of the fixing block;
[0007] The drive structure includes a lug connector disposed on the upper surface of the tension block, a moving rod hinged to the middle of the tension block, and a limiting rod hinged to the lower side of the tension block;
[0008] The guide assembly includes a connecting rod fixedly connected to the upper surface of the fixed block and a limiting sleeve disposed on one side of the connecting rod.
[0009] Furthermore, the lifting lug connector is rotatably mounted on the upper surface of the tensioning block, and there are two sets of both the moving rod and the limiting rod. The two sets of moving rod and limiting rod are symmetrically distributed on the front and rear sides of the tensioning block.
[0010] Furthermore, the clamping block is hinged between the two limiting rods and is located at the middle of the two limiting rods.
[0011] Furthermore, the ends of the two limiting rods away from the tensioning block are hinged to the lower side of the fixed block, and the ends of the two moving rods away from the tensioning block are hinged to the middle of the fixed block.
[0012] Furthermore, a fixing ring is fixedly connected to the end of the connecting rod away from the fixing block, and the limiting sleeve is detachably connected to the inside of the fixing ring. The limiting sleeve is a hollow cylinder.
[0013] Furthermore, there are two guide components, which are symmetrically distributed on the upper and lower sides of the fixed block.
[0014] Furthermore, anti-slip toothed plates are fixedly connected to the opposite side of the clamping block and the fixing block, and the anti-slip teeth of the two anti-slip toothed plates are distributed alternately between the clamping block and the fixing block.
[0015] Compared with the prior art, this utility model provides a detachable rebar clamp based on a crane, which has the following advantages:
[0016] 1. This crane-based detachable rebar clamp uses a movable rod hinged to the middle of the tensioning block as a driving force transmission component. When the crane passes through the lifting lug connector as a whole, the clamping block and the fixed block generate an inward clamping force during the upward movement. The greater the self-weight tension, the greater the clamping force, thereby achieving the driving and control of the entire structure. By adaptively adjusting the positions of the limit rod, movable rod, and fixed block, the clamping range of the clamping block can be adjusted to accommodate rebars of different sizes, thus ensuring the stability and reliability of the clamping force, improving its versatility and flexibility, and achieving the advantage of stable clamping.
[0017] 2. This crane-based detachable rebar clamp, through the symmetrical distribution of the upper and lower guide components, facilitates the guidance of the rebar during clamping, further enhancing the stability and balance of the structure. This allows the entire device to distribute force more evenly when under stress. The anti-slip teeth of the anti-slip plate are arranged in an interlaced pattern, making the clamping force distribution between the clamping block and the fixing block more uniform. This enables stable clamping of rebars of different diameters without the need to replace the clamp, improving construction efficiency and achieving the advantage of high construction efficiency.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1 to 4This embodiment of a crane-based detachable rebar clamp includes a tension block 1, a clamping block 2 disposed on the right side of the tension block 1, and a fixing block 3 disposed on the right side of the clamping block 2. A driving structure 4 is disposed on the outside of the tension block 1, and a guide component 6 is disposed on the outside of the fixing block 3. The driving structure 4 includes a lifting lug connector 41 disposed on the upper surface of the tension block 1, a moving rod 42 hinged to the middle of the tension block 1, and a limiting rod 43 hinged to the lower side of the tension block 1.
[0025] The lifting lug connector 41 is rotatably mounted on the upper surface of the tensioning block 1. There are two sets of moving rods 42 and two sets of limiting rods 43, symmetrically distributed on the front and rear sides of the tensioning block 1. By hinged to the middle of the tensioning block 1, the moving rod 42 serves as a force transmission component. When the crane passes through the lifting lug connector 41, the clamping block 2 and the fixed block 3 generate an inward clamping force during the lifting process. The greater the self-weight tension, the greater the clamping force, thus achieving the driving and control of the entire structure.
[0026] Specifically, the clamping block 2 is hinged between the two limiting rods 43 and is located in the middle of the two limiting rods 43.
[0027] It should be noted that the ends of the two limiting rods 43 furthest from the tensioning block 1 are hinged to the lower side of the fixed block 3, and the ends of the two moving rods 42 furthest from the tensioning block 1 are hinged to the middle of the fixed block 3. By symmetrically distributing the two sets of moving rods 42, this design not only improves the symmetry of the structure but also enhances the stability of the entire structure. The hinged design of the moving rods 42 allows the entire structure to better adapt to various deformations and displacements under stress. By adaptively adjusting the positions of the limiting rods 43, moving rods 42, and fixed block 3, the clamping range of the clamping block 2 can be adjusted, accommodating steel bars of different sizes, thereby ensuring the stability and reliability of the clamping force, improving its versatility and flexibility, and achieving the advantage of stable clamping.
[0028] In this embodiment, the guide component 6 includes a connecting rod 61 fixedly connected to the upper surface of the fixing block 3 and a limiting sleeve 62 disposed on one side of the connecting rod 61.
[0029] Among them, the end of the connecting rod 61 away from the fixed block 3 is fixedly connected to a fixed ring, and the limiting sleeve 62 is detachably connected to the inside of the fixed ring. The limiting sleeve 62 is a hollow cylinder.
[0030] Specifically, there are two guide components 6, which are symmetrically distributed on the upper and lower sides of the fixing block 3. The symmetrical distribution of the two guide components 6 facilitates the guidance during the clamping of the reinforcing bars, further enhancing the stability and balance of the structure, and enabling the entire device to distribute force more evenly when under stress.
[0031] In this embodiment, anti-slip toothed plates 5 are fixedly connected to opposite sides of the clamping block 2 and the fixing block 3, and the anti-slip teeth of the two anti-slip toothed plates 5 are distributed in an alternating manner between the clamping block 2 and the fixing block 3. By setting the anti-slip teeth of the anti-slip toothed plates 5 in an alternating manner, this design makes the clamping force distribution between the clamping block 2 and the fixing block 3 more uniform, and can achieve stable clamping of steel bars of different diameters.
[0032] The working principle of the above embodiments is as follows:
[0033] In use, the reinforcing bar is extended into the interior of the limiting sleeve 62, the crane hook is connected to the lifting lug connector 41, and the tension block 1 is lifted. The moving rod 42 is hinged to the middle of the tension block 1 as a driving force transmission component. When the crane is assembled through the lifting lug connector 41, the clamping block 2 and the fixed block 3 generate an inward clamping force during the lifting process. The greater the self-weight tension, the greater the clamping force, thereby realizing the driving and control of the entire structure. By adaptively adjusting the positions of the limiting rod 43, the moving rod 42 and the fixed block 3, the clamping range of the clamping block 2 can be adjusted. By setting the anti-slip teeth of the anti-slip tooth plate 5 to be staggered, this design makes the clamping force distribution between the clamping block 2 and the fixed block 3 more uniform, and can achieve stable clamping of reinforcing bars of different diameters. After the reinforcing bars are tied, the tension block 1 and clamping block 2 can be removed from the reinforcing bars. Then, the crane is operated to move the reinforcing bar clamp to the body of the reinforcing bar to be tied. This process is repeated until all the reinforcing bars are tied.
[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
