Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting equipment, and in particular relates to a hoisting device used for logistics transportation loading and unloading. Background Art

[0002] The hook is the most common type of lifting device in lifting machinery. The hook is often hung on the wire rope of the lifting mechanism with the help of pulleys and other components, and is used for logistics transportation and loading and unloading.

[0003] When the hook is used to connect with a thicker rope, when it is taken down again, the stopper acts on the rope in the opposite direction, and the opening of the hook is very limited, making it difficult to remove the rope, thereby causing the problem that it is difficult to remove the conventional hook after connecting with the thicker rope.

[0004] To this end, we proposed a lifting device for logistics transportation, loading and unloading to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that it is difficult to remove a conventional hook after it is butted against a thick rope, and proposes a lifting device for logistics transportation loading and unloading.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A lifting device for logistics transportation loading and unloading comprises a hook, the upper part of the hook is rotatably connected to a rotating frame, a stop bolt is slidably penetrated inside the rotating frame, a tension spring is arranged between the rotating frame and the stop bolt, the upper end of the tension spring is fixedly connected to the stop bolt, the lower end of the tension spring is fixedly connected to the rotating frame, a spring sheet is pressed on the side of the rotating frame, the lower end of the spring sheet is fixedly connected to a fixed block, the fixed block is fixedly connected to the hook, and the lower part of the stop bolt is movably inserted in the lower part of the hook. When taking out the lifting rope connected to the hook, the lower part of the stop bolt is pressed toward the inside of the hook to form an opening between the stop bolt and the hook, and the lifting rope is taken out from the opening. When the gap is close to the lifting rope, the stop bolt is pulled upward to make the stop bolt overcome the elastic force of the tension spring and move upward, thereby increasing the opening between the hook and the stop bolt, and facilitating the separation of the thicker lifting rope from the hook.

[0008] Preferably, the hook comprises a connecting ring and a hook body, a retaining groove is provided at the inner end of the hook body, and the connecting ring is fixedly connected to the upper end of the hook body.

[0009] Preferably, the hook further comprises a rotation limiting block, which is symmetrically fixedly connected to the upper end of the connecting ring. The rotation limiting block is used to conveniently limit the rotation range of the rotating frame.

[0010] Preferably, the hook further comprises a reinforcement block, which is fixedly connected between the connecting ring and the hook body, so as to increase the firmness between the connecting ring and the hook body.

[0011] Preferably, the rotating frame includes a guide sleeve, a swivel and a transmission block, wherein the guide sleeve is fixedly connected to the swivel, and the transmission block is symmetrically fixedly connected to the side end of the guide sleeve. The elasticity of the spring sheet is used to act upward on the transmission block, so that the transmission block acts on the guide sleeve, and the guide sleeve acts on the swivel. When the swivel loses the external force, it rotates with the elastic force of the spring sheet, which facilitates the resetting of the swivel.

[0012] Preferably, the stop bolt comprises a pull button and a bolt body, wherein the pull button is fixedly connected to the upper end of the bolt body. The pull button is pinched and pulled upward, so that the pull button overcomes the elastic force of the tension spring and moves upward, and the bolt body is driven to slide upward by the pull button, so as to increase the opening between the bolt body and the hook.

[0013] Preferably, the outer end of the pull button is provided with anti-skid grooves, so as to increase the friction between the hand and the pull button.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. When taking out the rope connected to the hook, press the lower part of the stop bolt toward the inside of the hook to form an opening between the stop bolt and the hook, and remove the rope from the opening. When the gap is close to the rope, pull the stop bolt upward to overcome the elastic force of the tension spring and move upward, thereby increasing the opening between the hook and the stop bolt and facilitating the separation of the thicker rope from the hook.

[0016] 2. Use the elasticity of the spring piece to act upward on the transmission block, so that the transmission block acts on the guide sleeve, and acts on the swivel through the guide sleeve. When the swivel loses the external force, it rotates with the help of the elastic force of the spring piece, which facilitates the resetting of the swivel.

[0017] 3. Pinch the pull button and pull it upward, so that the pull button overcomes the elastic force of the tension spring and moves upward, and the bolt body is driven to slide upward by the pull button, so as to increase the opening between the bolt body and the hook.
