Detailed Implementation
[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a mining electromechanical lifting device with overload protection function, including a crane 1, a lifting rope 2 on one side of the crane 1, a hook 3 on one side of the lifting rope 2, a protection device 4 on one side of the crane 1, the protection device 4 including a rectangular tube 41, a connecting device 5 between the rectangular tube 41 and the crane 1, a circular hole 42 on one side of the rectangular tube 41, a through hole 43 on one side of the rectangular tube 41, and a circular hole 42 on one side of the rectangular tube 41. A motor 45 is fixedly connected to one side of the hole 42. The output end of the motor 45 is fixedly connected to a winding rod 46 via a coupling. The winding rod 46 is placed inside the circular hole 42 and the rectangular tube 41. A rope 47 is fixedly connected to the surface of the winding rod 46. The rope 47 is placed inside the rectangular tube 41 and the through hole 43. A hook 48 is fixedly connected to the end of the rope 47 away from the winding rod 46. A stop block 49 is fixedly connected to one side of the rope 47. The stop block 49 is placed inside the rectangular tube 41 and is larger than the through hole 43. By setting up the protection device 4, when the lifting rope 2 and hook 3 are lifting the electromechanical equipment, the hook 48 is attached to the electromechanical equipment, and at the same time, the motor 45 runs synchronously with the winch on the lifting rope 2, so that during the winding process of the lifting rope 2, the winding rod 46 simultaneously winds the rope 47. When the lifting rope 2 breaks and the electromechanical equipment falls accidentally, the rope 47 moves away from the rectangular cylinder 41, causing the stop block 49 to move during the movement. When the stop block 49 moves to the position of the rectangular cylinder 41, the stop block 49 moves away from the rectangular cylinder 41. When the inner wall of the rectangular tube 41 is in contact with the stop block 49, the rectangular tube 41 and the stop block 49 intercept and limit the rope 47, so that the rope 47 intercepts and assists in suspending the falling mechanical and electrical equipment through the hook 48. This achieves overload protection for the hoist 1 when lifting the mechanical and electrical equipment, reduces the situation where the lifting rope 2 is overloaded and breaks due to aging, causing the mechanical and electrical equipment to fall and be damaged, and improves the safety of lifting the mechanical and electrical equipment.
[0021] A reinforcing block 411 is fixedly connected to the side of the rope 47 near the hook 48. The reinforcing block 411 is fixedly connected to the hook 48. By setting the reinforcing block 411, the connection strength between the hook 48 and the rope 47 can be increased, reducing the possibility of the rope 47 separating from the hook 48 after being stressed. A rubber pad 410 is fixedly connected to one side of the stop block 49. By setting the rubber pad 410, the stop block 49 can be separated from the inner wall of the rectangular tube 41, reducing the impact damage caused by the stop block 49 and the inner wall of the rectangular tube 41. A reinforcing rod 44 is fixedly connected to the surface of the rectangular tube 41. The reinforcing rod 44 is made of steel. By setting the reinforcing rod 44, the strength of the rectangular tube 41 can be improved, reducing the possibility of the rectangular tube 41 breaking or deforming after being impacted.
[0022] The connecting device 5 includes a locking frame 51, which is fixedly connected to the hoist 1. A threaded hole 52 is provided on one side of the locking frame 51, and a bolt 53 is threaded onto the inner wall of the threaded hole 52. A perforated plate 55 is fixedly connected to one side of the rectangular tube 41. The surface of the perforated plate 55 is slidably inserted into the inner wall of the locking frame 51. The size and shape of the bolt 53 are adapted to the size and shape of the inner wall of the perforated plate 55. By setting the connecting device 5, the rectangular tube 41 is first manually moved to move the perforated plate 55. When the perforated plate 55 moves to the position where it is locked into the locking frame 51, the inner wall of the perforated plate 55 is threaded into the locking frame 51. The inner walls of the hole 52 overlap. At this time, the bolt 53 is screwed into the threaded hole 52 and the hole plate 55 with a tool to fix the position of the hole plate 55 and the rectangular tube 41, thereby achieving the assembly and fixation between the protection device 4 and the crane 1. At the same time, the protection device 4 can be disassembled later, improving the flexibility of use and the convenience of maintenance of the protection device 4. A support block 54 is fixedly connected to one side of the locking frame 51. The support block 54 is fixedly connected to the crane 1. By setting the support block 54, the connection strength between the locking frame 51 and the crane 1 can be increased, reducing the possibility of the locking frame 51 separating from the crane 1 after being subjected to force.
[0023] The working principle of this utility model is as follows: First, the hoist 1 is moved to the designated position, and then the hook 3 is attached to the electromechanical equipment. Then, the winch is used to wind up the hoisting rope 2, so that the hoisting rope 2 drives the hook 3 to move during the winding process, and the hook 3 lifts the electromechanical equipment during the movement, thereby completing the lifting and transfer of the electromechanical equipment.
[0024] First, manually move the rectangular tube 41 to move the perforated plate 55. When the perforated plate 55 moves to the position where it is inserted into the slotted frame 51, the inner wall of the perforated plate 55 coincides with the inner wall of the threaded hole 52. At this time, use a tool to screw the bolt 53 into the threaded hole 52 and the perforated plate 55 to fix the position of the perforated plate 55 and the rectangular tube 41, thereby achieving the assembly and fixation between the protection device 4 and the crane 1.
[0025] When the lifting rope 2 and hook 3 are lifting the electromechanical equipment, the hook 48 is attached to the equipment. At the same time, the motor 45 runs synchronously with the winch on the lifting rope 2, so that during the winding process of the lifting rope 2, the winding rod 46 simultaneously winds the rope 47. When the lifting rope 2 breaks and the electromechanical equipment falls accidentally, the rope 47 moves away from the rectangular cylinder 41. During the movement of the rope 47, the stop block 49 moves. When the stop block 49 moves to a position that fits against the inner wall of the rectangular cylinder 41, the rectangular cylinder 41 cooperates with the stop block 49 to intercept and limit the rope 47. The rope 47 intercepts and assists in suspending the falling electromechanical equipment through the hook 48, thereby achieving overload protection for the crane 1 when lifting the electromechanical equipment.
