This device is crucial for ensuring the quality and production efficiency of castings.

[0003] Although the existing shell casting hoisting devices have advantages such as improving production efficiency and reducing labor costs

[0004] However, during the process of hoisting the shell by personnel, it is not easy to give an early warning of excessive pulling force on the shell, resulting in inconvenient use of the hoisting device and not being easy to quickly fix the shell. Therefore, a shell casting hoisting device is proposed for the above problems. Summary of the Utility Model

Then, the staff can turn on the power supply of the driving motor to make the wire reel rotate.

Specific embodiments

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 4 shown, the present invention provides a mold shell pouring hoisting device, including a guide rail 1. Track grooves are provided on both sides of the top surface of the guide rail 1. A moving block 2 is slidably connected inside the track groove. A towing rope 3 is fixedly installed at the center of the bottom surface of the moving block 2. A battery 13 is fixedly installed on the front surface of the guide rail 1. The power supply end of the battery 13 is electrically connected to the inside of the moving block 2. Reinforcing rods 14 are fixedly installed on both sides of the inner wall of the guide rail 1. A connecting rod 15 is fixedly installed in the middle of the surface of the reinforcing rod 14.

[0023] When a person uses the mold shell pouring hoisting device, the mold shell to be poured can be placed at the bottom of the guide rail 1. The person can fix the surface of the mold shell by using the hook 93 and the powerful vacuum sucker 94. Then, the power supply of the driving motor 5 is turned on, so that the wire reel 6 rotates self - sufficiently. Immediately, the connecting rope 7 starts to be wound up, so that the connecting rope 7 drives the stabilizing plate 91 and the hook rope 92 to move slowly upward. Then, the person turns on the power supply of the moving block 2 again, so that the moving block 2 slides along the track, and the mold shell is moved to a suitable pouring position. At the same time, when the weight of the mold shell is too large, the tension sensor 81 detects the pressure received by the connecting rope 7. Immediately, when the tension exceeds the preset tension value, the tension sensor 81 places the overload data inside the microcontroller 82. Then, the microcontroller 82 can interrupt the power supply of the driving motor 5, so that the wire reel 6 stops operating. Then, the situation that the driving motor 5 idles due to excessive tension, resulting in the accidental dropping of the mold shell, is reduced.

[0024] As Figures 1 to 4 shown, a placing plate 4 is fixedly installed at the bottom of the towing rope 3. A driving motor 5 is fixedly installed on one side of the top surface of the placing plate 4. The output end of the driving motor 5 is fixedly installed with a wire reel 6. A connecting rope 7 is wound around the surface of the wire reel 6.

[0025] By setting up the drive motor 5 and the take-up drum 6, when personnel are hoisting the mold shell, they turn on the power of the drive motor 5 to make the take-up drum 6 rotate, and then the connecting rope 7 is wound around the surface of the take-up drum 6, so that it is convenient for personnel to control the function of the connecting rope 7.

[0026] like Figures 1 to 4 As shown, a tension warning mechanism 8 is fixedly installed at one end of the connecting rope 7, and the tension warning mechanism 8 includes a tension sensor 81. The interior of the tension sensor 81 is fixedly installed on one side of the surface of the connecting rope 7, and the other side of the tension sensor 81 is electrically connected to a microcontroller 82. The control end of the microcontroller 82 is electrically connected to a power cord 10, and one end of the power cord 10 is electrically connected to the power end of the drive motor 5.

[0027] Through the cooperation of the tension warning mechanism 8, the drive motor 5 and the take-up drum 6, when the weight of the connecting rope 7 hoisting the mold shell is too heavy, the tension sensor 81 can detect the tension on the connecting rope 7. Subsequently, when the microcontroller 82 receives the tension excessive data information from the tension sensor 81, the microcontroller 82 interrupts the power supply of the drive motor 5, causing the take-up drum 6 to stop working, thereby reducing the situation where the drive motor 5 is idling due to the excessive weight of the hoisting mold shell.

[0028] like Figures 1 to 4 As shown, a lifting assembly 9 is fixedly installed at the bottom of the tension warning mechanism 8, and the lifting assembly 9 includes a stabilizing plate 91. The middle of the top surface of the stabilizing plate 91 is fixedly connected to the axis of one end of the connecting rope 7, and hook ropes 92 are fixedly installed on both sides of the bottom of the stabilizing plate 91. A hook 93 is fixedly connected to one end of the hook rope 92, and a strong vacuum suction cup 94 is fixedly installed on one side of the hook rope 92.

[0029] By setting the lifting assembly 9 and the driving motor 5, when personnel lift the mold shell, they can place the hook 93 on one side of the outer surface of the mold shell, and then use the strong vacuum suction cup 94 to adsorb it to the surface of the mold shell, so that the mold shell can be fixed, thereby facilitating personnel to quickly fix the mold shell during the process of lifting the mold shell.

[0030] like Figures 1 to 4 As shown, mounting blocks 11 are fixedly mounted on both sides of the guide rail 1 , and fixing bolts 12 are threadedly penetrated through the surfaces of the mounting blocks 11 .

[0031] The installation block 11 and the fixing bolt 12 are arranged to facilitate personnel to quickly fix the guide rail 1 to a designated working position.

[0032] Working principle and usage process of the utility model: When a user uses the mold shell pouring and hoisting device, the mold shell to be poured can be placed at the bottom of the guide rail 1. The user can fix the surface of the mold shell by using the hook 93 and the powerful vacuum suction cup 94. Then, the power supply of the driving motor 5 is turned on, causing the wire winding disc 6 to rotate. Immediately, the connecting rope 7 starts to wind up, driving the stabilizing disc 91 and the hook rope 92 to slowly move upward. Subsequently, the user turns on the power supply of the moving block 2 again, causing the moving block 2 to slide along the track, moving the mold shell to a suitable pouring position. At the same time, when the weight of the mold shell is too large, the tension sensor 81 detects the pressure on the connecting rope 7. When the tension exceeds the preset tension value, the tension sensor 81 places the overload data inside the microcontroller 82. Then, the microcontroller 82 can interrupt the power supply of the driving motor 5, causing the wire winding disc 6 to stop operating, thereby reducing the occurrence of the situation where the driving motor 5 idles due to excessive tension, resulting in the accidental dropping of the mold shell.
