Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically to a rope locking device for hoisting a reinforced concrete steel socket pipe. Background Art

[0002] Concrete steel, also known as floor deck or steel deck, is a pressed steel plate used to support floor concrete. It is usually designed to work with concrete to form an integral structure, thereby enhancing the load-bearing capacity and rigidity of the floor. Safety is a crucial consideration when it comes to lifting concrete steel. The weight of concrete steel is often quite large and comes in various shapes and sizes, which poses a great challenge to the lifting process. However, many existing lifting devices are not very effective in fixing concrete steel, mainly because they mainly rely on simple clamping plates for clamping. Although such clamping plates seem simple and straightforward, they have many safety hazards in actual application. First, the contact area between the clamping plate and the concrete steel is limited, which leads to uneven distribution of clamping force and is prone to shaking or slipping during lifting. Second, the clamping force of the clamping plate is often difficult to control accurately. Too tight may cause damage to the surface of the concrete steel, while too loose cannot ensure a stable fixation. More importantly, if the concrete steel bearing is loose during the lifting process due to loose clamping, it will bring extremely serious consequences. First, the fallen concrete steel bearing may injure people on the ground or damage surrounding equipment, causing personal injury and property loss. Second, the fallen concrete steel bearing may also damage the lifting equipment itself, or even cause more serious safety accidents. Utility Model Content

[0020] When in use, the staff moves the concrete steel bearing 14 to a vertical state, and then the staff starts the motor 10 through an external switch. The power generated by the motor 10 causes the main gear 9 to rotate. Since the main gear 9 is meshed with the slave gear 8, the main gear 9 drives the slave gear 8 to rotate synchronously while rotating. The rotation of the slave gear 8 causes the threaded rod 4 to rotate through the connecting shaft 7, and the sleeve block 5 on the surface of the threaded rod 4 is driven to move through the rotation of the threaded rod 4, so that the movable plate 6 gradually approaches the fixed plate 2, and then the surface of the concrete steel bearing 14 is clamped by the two clamping plates 12, and at the same time, the spring 13 on the surface of the lifting and retracting rod 11 is in a compressed state;

[0021] The power of the motor 10 causes the slave gear 8 meshing with the main gear 9 to rotate. The rotation of the slave gear 8 causes the sleeve block 5 movably installed on the surface of the threaded rod 4 to move through the connecting shaft 7 and causes the movable plate 6 at its bottom to gradually approach the fixed plate 2, so that the two clamping plates 12 clamp the concrete steel bearing 14 and the spring 13 is in a compressed state. This device can ensure the close fit between the clamping plates 12 and the concrete steel bearing 14 by adjusting the distance between the clamping plates 12, thereby enhancing the stability and bearing capacity of the structure, thereby helping to prevent safety accidents caused by structural instability during the lifting process, and at the same time ensure that the concrete steel bearing 14 is subjected to uniformly distributed pressure during the lifting process, thereby reducing its deflection and deformation, thereby helping to improve the accuracy and service life of the concrete steel bearing 14, and through the cooperation of the lifting and retracting rod 11 and the spring 13, the fixing force can be accurately controlled according to the weight and size of the concrete steel bearing 14, thereby helping to ensure the stability and safety of the concrete steel bearing 14 during the lifting process.

[0022] Wherein, both ends of the concrete steel bearing 14 are provided with U-shaped clamping rings 15, and the two U-shaped clamping rings 15 are made of iron;

[0023] U-shaped clamping rings 15 are provided at both ends of the concrete steel bearing 14. The two U-shaped clamping rings 15 are both made of iron. Through the coordinated use of the two U-shaped clamping rings 15, they will be locked at both ends of the concrete steel bearing 14 under the action of gravity, thereby well protecting the steel socket of the pipe mouth.

[0024] The main gear 9 is provided with a motor protection cover 18 on its surface and the motor 10 is located inside the motor protection cover 18. The motor protection cover 18 is provided with heat dissipation holes 19 on its surface.

[0025] A motor protection cover 18 is provided on the surface of the main gear 9 and the motor 10 is located inside the motor protection cover 18. The motor protection cover 18 protects the motor 10 inside from being damaged by impact of external objects. Heat dissipation holes 19 are opened on the surface of the motor protection cover 18. The heat dissipation holes 19 ensure that the motor 10 can quickly dissipate heat during operation.

[0026] Among them, a hook 20 is fixedly installed on the top of the rectangular plate 1, and the hook 20 is located at the top center of the rectangular plate 1;

[0027] A hook 20 is fixedly installed on the top of the rectangular plate 1, and the hook 20 is located at the top center of the rectangular plate 1. Through the use of the hook 20 and the cooperation between the crane and the hook 20, the rectangular plate 1 as a whole can be moved more quickly.

[0028] Wherein, a rubber layer is provided on the inner wall of the clamping plate 12, and the two clamping plates 12 are equal in size;

[0029] A rubber layer is provided on the inner wall of the clamping plate 12, and the rubber layer can prevent the clamping plate 12 from causing damage to the surface of the concrete steel bearing 14 when clamping the concrete steel bearing 14. The two clamping plates 12 are equal in size, so that the clamping force on the concrete steel bearing 14 is more uniform.

[0030] A slide groove 16 is provided on the inner wall of the rectangular groove 3, a slider 17 is movably installed inside the slide groove 16, and the slider 17 is fixedly connected to the sleeve block 5;

[0031] When the sleeve block 5 moves on the surface of the threaded rod 4 , the cooperation between the slide groove 16 and the slider 17 can make the sleeve block 5 more stable during the movement, thereby improving the clamping effect of the clamping plate 12 .

[0032] The working principle and use process of this utility model:

[0033] When in use, the staff moves the concrete steel bearing 14 to a vertical state, and then starts the motor 10 through an external switch. The power generated by the motor 10 causes the main gear 9 to rotate. Since the main gear 9 is meshed with the slave gear 8, the main gear 9 simultaneously drives the slave gear 8 to rotate. The rotation of the slave gear 8 causes the threaded rod 4 to rotate through the connecting shaft 7, and the rotation of the threaded rod 4 drives the socket block 5 on its surface to move, so that the movable plate 6 gradually approaches the fixed plate 2, and then the surface of the concrete steel bearing 14 is clamped by two clamping plates 12, and at the same time, the spring 13 on the surface of the lifting and retracting rod 11 is in a compressed state.
