Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a multi-section steel beam hoisting and unloading system and a use method thereof. Background Art

[0002] Steel beams are commonly used structural members in construction. The weight of the steel beams themselves is relatively large, and they need to be hoisted during the construction process. When hoisting traditional steel beams, hoisting holes must be opened on the steel beams or lifting ears must be welded on the steel beams. They must be connected to the steel wire ropes using clamps, and then hoisted using vertical transportation machinery such as tower cranes.

[0003] During the on-site construction of high-rise steel structures, it is necessary to lift steel beams and other components. The length of such steel beam components is generally between 3 meters and 10 meters, and the weight is not large, but there are many types and quantities. Traditional lifting components can only lift one steel beam component at a time, and the lifting efficiency is low, which affects the construction efficiency. For this reason, a multi-section steel beam lifting and unloading system and a use method thereof are proposed, which can synchronously lift multiple groups of steel beams and unload them one by one, thereby effectively improving the lifting and unloading efficiency of the steel beams, and a positioning component is provided, which can stably bear the load and position the lifted steel beams during the lifting process, thereby ensuring the safety during the positioning and transportation process. Summary of the invention

[0004] The present invention provides a multi-section steel beam lifting and unloading system and a use method thereof, which solves the problems raised by the above-mentioned existing background technology, can effectively improve the conveying efficiency of steel beams, is suitable for lifting steel beams of different lengths, has good applicability, and is provided with a safety component, which can stably bear the load and position the lifted steel beams during the lifting process, and has good safety.

[0005] The solution of the present invention to solve the above technical problems is as follows: a multi-section steel beam lifting and unloading system comprises a lifting beam body, a main lifting rope, a main lifting belt, and a steel beam body, the main lifting rope is a Y-shaped structure, the main lifting rope is fixedly connected to a No. 1 safety hook, the lifting beam body is fixedly connected to a No. 1 hanging ring, the main lifting rope is connected to the No. 1 hanging ring through the No. 1 safety hook, the lifting beam body is fixedly connected to a connecting frame, the connecting frame is connected to the main lifting belt, the main lifting belt is provided with five, and the five main lifting belts are evenly arranged and installed at the connecting frame, the main lifting belt is fixedly connected to a No. 1 auxiliary lifting belt, a No. 2 auxiliary lifting belt, and a No. 2 lifting ring, the No. 1 auxiliary lifting belt is fixedly connected to a No. 2 safety hook, the No. 2 auxiliary lifting belt is fixedly connected to a No. 3 safety hook, the steel beam body is evenly installed with a No. 3 lifting ring, the lifting beam body is fixedly connected to a storage box, the storage box is fixedly connected to a brake stepping motor, the brake stepping motor is fixedly connected to a winding roller, and the outer wall of the winding roller is fixedly connected to a winding disk;

[0006] The method of use includes the following steps:

[0007] S1: Place the main beam on the ground, lay multiple sets of main lifting belts flat on the ground, evenly place multiple steel beams on the main lifting belts, first connect the No. 3 safety hook of the No. 2 auxiliary lifting belt with the No. 3 lifting ring of the steel beam, so that the steel beam can be initially positioned on the main lifting belt, then connect the No. 2 safety hook of the No. 1 auxiliary lifting belt with the No. 2 lifting ring of the main lifting belt to complete the loading, and evenly place multiple sets of steel beams one by one on the main lifting belt for positioning;

[0008] S2: Connect the hook of the crane equipment with the No. 1 hanging ring of the main lifting rope, and connect the No. 1 safety hook of the main lifting rope with the connecting frame of the lifting beam body to start the crane equipment for lifting operation. During lifting, multiple steel beam bodies can be transported in series. When the steel beam body at the bottom reaches the unloading position, it can be stopped. After releasing the No. 2 safety hook and the No. 2 lifting ring, release the No. 3 lifting ring and the No. 3 safety hook to release the positioning. After the steel beam body is out, connect the No. 2 safety hook with the No. 2 lifting ring again. After one steel beam body is transported to the unloading position, the crane equipment can lift it again to transport and unload the next steel beam body without moving to the bottom to load again;

[0009] S3: After the unloading of a steel beam body is completed, the brake stepper motor can be started to rotate the winding roller, and the winding roller can drive the winding disk to rotate in the storage box to reel in the excess lifting belt, so that the main lifting belt at the bottom of the feeding steel beam body can be stored, thereby preventing the excess main lifting belt from affecting the unloading and conveying operation;

[0010] S4: After the transportation is completed, the main body of the lifting beam can be lifted to the ground. By starting the brake stepper motor, the main lifting belt can be released from the storage box to carry out the loading operation of the steel beam main body again.

[0013] Furthermore, each of the main lifting belts is evenly provided with a plurality of No. 1 auxiliary lifting belts, No. 2 auxiliary lifting belts and No. 2 lifting rings, and the plurality of No. 1 auxiliary lifting belts and No. 2 auxiliary lifting belts can respectively carry out load-bearing and positioning processing on the steel beam body.

[0014] Furthermore, five reel drums are provided corresponding to the main lifting belts, so that the five main lifting belts can be evenly stored in the storage box.

[0015] Furthermore, a collecting hole is provided at the bottom of the storage box corresponding to the main lifting belt, and a guide roller is rotatably connected to the inner wall of the collecting hole, so that the reeling and unreeling of the main lifting belt can be more stable.

Multiple groups of steel beam bodies are evenly placed one by one at the main lifting belt for positioning, so that the main lifting belt can bear and position multiple groups of steel beam bodies respectively;

[0019] 2. During hoisting, multiple steel beam bodies can be hoisted in series for transportation. When the bottom steel beam body reaches the unloading position, it can be stopped. After releasing the No. 2 safety hook and the No. 2 lifting ring, the No. 3 lifting ring and the No. 3 safety hook can be released to release the positioning. After the steel beam body is pulled out, the No. 2 safety hook is connected to the No. 2 lifting ring again. After one steel beam body is transported to the unloading position, the crane equipment can be lifted again to transport and unload the next steel beam body. There is no need to move to the bottom to load again, so that the steel beam body can be quickly hoisted and unloaded;

[0020] 3. The winding roller can drive the winding disk to rotate in the storage box to reel in the excess lifting belt, so that the main lifting belt at the bottom of the steel beam body being fed can be stored, thereby preventing the excess main lifting belt from affecting the unloading and conveying operation;

[0021] 4. Such a multi-section steel beam lifting and unloading system and its use method can synchronously lift multiple groups of steel beams and unload them one by one, thereby effectively improving the lifting and unloading efficiency of the steel beams.
