Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cranes, in particular to a crane for preventing products from falling. Background Art
[0002] Industrial machinery refers to mechanical equipment used in industrial construction and industrial manufacturing to replace or assist manual labor. They are collectively called industrial machinery. Cranes refer to multi-action lifting machinery that vertically lifts and horizontally transports heavy objects within a certain range. They are also called overhead cranes, overhead cranes, and cranes. Large cranes generally use electromagnetic attraction to absorb objects.
[0003] Current cranes generally use hooks to lift workpieces. During operation, the hook may become unhooked or broken. After the heavy object is unhooked, the hook tends to rebound due to the tension of the wire rope, colliding with the mechanical parts of the crane and causing damage to the equipment. During lifting, the heavy object is at a certain distance from the ground. When unhooking, the heavy object detaches from the hook and falls from a high altitude to the ground. The heavy object is damaged by the impact and is likely to injure construction workers when it falls, which in turn causes safety accidents. Utility Model Content

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0020] Reference Figure 1-4 A crane for preventing products from falling includes a crane body 1, a hook 2 is provided inside the crane body 1, a cargo box 5 is provided at the bottom end of the hook 2, steel ropes 4 are fixedly connected to the four corners of the top of the cargo box 5, and reinforcing balls 3 are fixedly installed between the four steel ropes 4. The steel ropes 4 are all hung with the hook 2, and the reinforcing balls 3 are provided inside the hook 2. A second pin 15 is provided between the hook 2 and the reinforcing balls 3. Sockets for use with the second pin 15 are opened inside the hook 2 and the reinforcing balls 3. The second pin 15 passes through the inside of the socket, and one end of the outer side of the second pin 15 is provided with an external thread. The outer side of the pin 15 is threadedly connected with a locking nut 20. When the crane body 1 needs to be used to lift the cargo box 5, the steel rope 4 can be hung on the hook 2 inside the crane body 1, and the reinforcing ball 3 can be placed inside the hook 2. Then the second pin 15 is used to fix the reinforcing ball 3 and the hook 2, thereby preventing the steel rope 4 from falling off from the hook 2. The use of the steel rope 4 can increase the connection relationship between the hook 2 and the cargo box 5 on the basis of the fixation of the second pin 15, further improving the stability of the cargo box 5 and avoiding the steel rope 4 from falling off during the lifting process and causing a safety accident.
[0021] Reference Figure 4A locking mechanism is provided on the outside of the hook 2, and the locking mechanism includes two brackets 16 fixedly connected to the outer wall of the hook 2, and a rotating shaft is fixedly connected between the two brackets 16. The middle part of the rotating shaft is rotatably connected to a clamping plate 18. A torsion spring 17 is provided on the outside of the rotating shaft and on both sides of the clamping plate 18. One end of the torsion spring 17 overlaps the clamping plate 18, and the other end of the torsion spring 17 overlaps the bracket 16. Through the setting of the torsion spring 17, the clamping plate 18 can be driven to clamp with the clamping groove 19, so that the hook 2 forms a closed loop, avoiding the falling off of the reinforcing ball 3 during the lifting process, and further improving the lifting stability of the cargo box 5.
[0022] Reference Figure 2 A control mechanism is provided on the outside of the hook 2, and the control mechanism includes a pressure sensor 13 fixedly installed inside the hook 2 and located below the reinforcing ball 3. A wireless signal transceiver 7 is fixedly installed on the outside of the hook 2, and a controller 8 is fixedly installed on the outside of the cargo box 5. An electric drag parachute 12 is provided at the bottom end of the cargo box 5. When the reinforcing ball 3 and the steel rope 4 on the cargo box 5 fall off or break from the hook 2, the pressure sensor 13 in the hook 2 cannot sense the weight of the reinforcing ball 3, and will transmit the information to the wireless signal transceiver 7. Subsequently, the information will be transmitted to the controller 8, and the electric drag parachute 12 will be controlled by the controller 8 to automatically open, thereby providing a certain resistance to the descent of the cargo box 5 and the cargo, thereby preventing the cargo box 5 from falling too fast and causing damage to the cargo.
[0023] Reference Figure 2 The interior of the cargo box 5 is provided with a closing mechanism, which includes slots 9 equidistantly opened on both sides of the inner wall of the cargo box 5. Insert blocks are clamped inside the slots 9, and a clamping plate 6 is fixedly connected between the two insert blocks. By cooperating with the insert blocks and the slots 9, the position of the clamping plate 6 can be adjusted according to the size of the cargo, and the top of the cargo can be clamped by the clamping plate 6 to prevent the risk of cargo spilling out of the cargo box 5 during the falling process.
[0024] Reference Figure 2 A protective door is hinged on the outside of the cargo box 5, and a fixed block 2 14 is fixedly connected to one side of the protective door. Two fixed blocks 11 are fixedly connected to one side of the cargo box 5. A first latch 10 is inserted between the two fixed blocks 11 and the fixed block 2 14. The protective door and the cargo box 5 can be fixed by the first latch 10.
[0025] Reference Figure 4 The locking nut 20 is in conflict with the outer side of the hook 2, and the interior of the hook 2 is provided with a snap-in groove 19 used in conjunction with the snap-in plate 18. The snap-in groove 19 is snap-fitted with the snap-in plate 18, which can form a closed loop for the hook 2 and play a certain anti-slip effect.
[0026] Working principle: First, when the crane body 1 needs to be used to lift the cargo box 5, the steel rope 4 can be hung on the hook 2 inside the crane body 1, and the reinforcing ball 3 can be placed inside the hook 2. Then, the second latch 15 is used to fix the reinforcing ball 3 and the hook 2, thereby preventing the steel rope 4 from falling off from the hook 2. The use of the steel rope 4 can increase the connection between the hook 2 and the cargo box 5 on the basis of the fixation of the second latch 15, and the setting of the torsion spring 17 can drive the clamping plate 18 to clamp with the clamping groove 19, so that the hook 2 forms a closed loop, avoiding the reinforcing ball 3 from falling off during the lifting process, further improving the lifting stability of the cargo box 5, and avoiding the steel rope 4 from falling off during the lifting process to cause a safety accident;
[0027] When the reinforcing ball 3 and the steel rope 4 on the cargo box 5 fall off or break from the hook 2, the pressure sensor 13 in the hook 2 cannot sense the weight of the reinforcing ball 3, and will transmit the information to the wireless signal transceiver 7. Subsequently, the information will be transmitted to the controller 8, and the controller 8 will control the electric drag parachute 12 to automatically open, providing a certain resistance for the descent of the cargo box 5 and the cargo, thereby preventing the cargo box 5 from falling too fast and causing damage to the cargo.
