Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a steel bar handling device for residential building construction. Background Art

[0002] In the field of residential building construction, steel bars, as key materials for constructing building skeletons, the handling efficiency and safety thereof are directly related to the progress, cost of the entire project, and the quality of the final building. Traditional steel bar handling methods mainly rely on manual handling or the use of simple mechanical devices, such as cranes, forklifts, etc. However, these methods all have obvious limitations in practical applications.

[0003] Manually handling steel bars not only has a high labor intensity and low efficiency, but also is prone to causing worker injuries due to improper operation. Especially when handling long and heavy steel bars, the risk is higher. In addition, it is difficult to ensure the stability of steel bars during transportation by manual handling, and safety hazards such as steel bar tilting and slipping are likely to occur.

[0004] In contrast, although using mechanical equipment such as cranes or forklifts for handling can improve efficiency, there are still many problems. Cranes require a large working space, and the operation is complex, with high technical requirements for operators. In a narrow construction site, the flexibility of cranes is limited, and it is difficult to complete operations efficiently. Forklifts, although having good flexibility, when handling long steel bars, since the length of the steel bar exceeds the range of the forklift forks, auxiliary devices often need to be installed at both ends of the steel bar, increasing the complexity of the operation.

[0005] Moreover, whether it is manual handling or mechanical handling, it is difficult to effectively solve the problem of the steel bar sagging and rubbing against the ground during transportation. During the transportation of long steel bars, due to the influence of its own gravity and vehicle bumps, both ends are prone to sag and contact the ground, which will not only wear the surface of the steel bar, affecting its service life and safety, but also may generate sparks due to friction, triggering safety accidents such as fires. Summary of the Utility Model

[0006] Aiming at the above problems, the purpose of the utility model is to provide a steel bar handling device for residential building construction, which solves the problems that traditional steel bar handling methods mostly rely on manual labor or simple machinery, have low handling efficiency, high labor intensity, and are prone to causing the steel bar to sag at both ends and rub against the ground during transportation, resulting in damage or pollution to the surface of the steel bar.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is: a steel bar transporting device for residential building construction, including a vehicle body, wheels are installed at the bottom of the vehicle body, a lifting mechanism is installed on the vehicle body, steel bars are placed on the vehicle body on both sides of the lifting mechanism, a lifting platform in the lifting mechanism is tied to one end of a steel wire rope, the other end of the steel wire rope is tied to a clamping piece, and the clamping piece is tied and fixed to both ends of the steel bar.

[0008] The beneficial effects of the utility model are as follows: through the lifting mechanism driven by the steel wire rope and the screw rod, the two ends of the steel bar are automatically lifted, the two ends of the steel bar are tightened, and the steel bar is effectively prevented from sagging and rubbing against the ground during transportation, thereby protecting the surface quality of the steel bar and transportation safety.

[0009] In order to ensure the stability of the lifting platform;

[0010] As a further improvement of the above technical solution: the lifting mechanism includes a screw, which is rotatably clamped on the vehicle body, and a polished rod is installed on the vehicle body on both sides of the screw. The lifting platform is threadedly connected to the screw and slidably connected to the polished rod. The top end of the screw is rotatably clamped to a fixed plate, and the top end of the polished rod is connected to the fixed plate.

[0012] In order to ensure the safe use of the lifting mechanism;

[0013] As a further improvement of the above technical solution: the lead screw is a trapezoidal lead screw structure.

[0014] The beneficial effect of this improvement is that the self-locking property of the trapezoidal thread structure of the lead screw can effectively ensure the safety and stability of the lifting mechanism in pulling the wire rope.

[0015] In order to save effort in turning the lead screw;

[0016] As a further improvement of the above technical solution: a hand wheel is installed at the top end of the lead screw.

[0017] The beneficial effect of this improvement is that the operator can turn the lead screw with less effort through the hand wheel.

[0018] In order to firmly bind and fix the steel bars;

[0019] As a further improvement of the above technical solution: the clamping member includes a binding belt and a heavy-load hanging ring, both ends of the binding belt are provided with quick buckles, the binding belt is hung with a heavy-load hanging ring, and the heavy-load hanging ring is hung to connect the wire rope.

[0020] The beneficial effects of this improvement are as follows: The binding belt can be firmly bound to the steel bar, enabling the steel wire rope to stably pull and lift both ends of the steel bar.

[0021] To ensure the stability of the steel bar during transportation on the vehicle body;

[0022] As a further improvement of the above technical solution: Internal threaded hole structures for threadedly connecting the limiting rods are provided at the four corners of the vehicle body.

[0023] The beneficial effects of this improvement are as follows: After the steel bar is placed on the surface of the vehicle body, the limiting rod can be rotated and inserted into the vehicle body, thereby realizing the support and protection of the steel bar and ensuring the stability of the steel bar during transportation on the vehicle body.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0030] Embodiment 1:

[0031] As Figure 1As shown in Figure 3, a steel bar handling device for residential building construction includes a vehicle body 1. Wheels 2 are installed at the bottom of the vehicle body 1. A lifting mechanism 3 is installed on the vehicle body 1. Steel bars 7 are placed on the vehicle body 1 on both sides of the lifting mechanism 3. One end of a steel wire rope 5 is tied and connected to a lifting platform 35 in the lifting mechanism 3, and the other end of the steel wire rope 5 is tied and hung on a clamping member 6. The clamping member 6 is tied and fixed at both ends of the steel bar 7. Through the steel wire rope 5 and the lifting mechanism 3 driven by a lead screw, automatic lifting of both ends of the steel bar 7 is achieved, and both ends of the steel bar 7 are tightened, effectively preventing the steel bar 7 from sagging and rubbing against the ground during transportation, protecting the surface quality of the steel bar 7 and transportation safety. The lifting mechanism 3 includes a lead screw 32. The lead screw 32 is rotatably clamped on the vehicle body 1. Optical rods 31 are installed on the vehicle body 1 on both sides of the lead screw 32. The lifting platform 35 is threadedly connected to the lead screw 32 and slidably connected to the optical rods 31. The top end of the lead screw 32 is rotatably clamped to a fixing plate 33, and the top end of the optical rod 31 is connected to the fixing plate 33. The optical rod 31 plays a role of limiting and supporting, enabling the lifting platform 35 to move and lift stably driven by the rotating lead screw 32. The lead screw 32 has a trapezoidal lead screw structure. The self-locking property of the trapezoidal thread structure of the lead screw 32 can effectively ensure the safety and stability of the lifting mechanism 3 in pulling the steel wire rope 5. A handwheel 34 is installed at the top end of the lead screw 32, and an operator can rotate the lead screw 32 labor-savingly through the handwheel 34. The clamping member 6 includes a binding belt 61 and a heavy-duty hanging ring 62. Quick-release buckles are provided at both ends of the binding belt 61. A heavy-duty hanging ring 62 is tied and hung on the binding belt 61. The heavy-duty hanging ring 62 is tied and connected to the steel wire rope 5. The binding belt 61 can be firmly tied to the steel bar 7, enabling the steel wire rope 5 to stably pull and lift both ends of the steel bar 7. Internal threaded hole structures for threadedly connecting limit rods 4 are provided at the four corners of the vehicle body 1. After the steel bars are laid on the surface of the vehicle body 1, the limit rods 4 are rotated and inserted onto the vehicle body 1, and thus the support and protection of the steel bar 7 can be realized, ensuring the stability of the steel bar 7 during transportation on the vehicle body 1.

[0032] The working principle of this technical solution is as follows: When in use, first, the middle part of the steel bar 7 is placed stably on the vehicle body 1 on both sides of the lifting mechanism 3. Then, limit rods 4 are screwed into the vehicle body 1 on both sides of the steel bar 7 for supporting and limiting the steel bar 7. Subsequently, clamping members 6 are installed at both ends of the steel bar 7. The clamping members 6 should be installed at positions where the steel wire rope 5 is straightened. Subsequently, the operator manually rotates the handwheel 34. The handwheel 34 drives the lead screw 32 to rotate. The lifting platform 35 moves upward under the limitation of the optical rod 31, and then pulls one end of the steel wire rope 5, lifting both ends of the steel bar 7 through the steel wire rope system until the steel bar 7 completely leaves the ground, avoiding sagging and rubbing during transportation.
