Hook 8; the pushing mechanism includes a plurality of pushing platforms 9 installed on the traction chain 2, a guide cylinder 10 is installed on the upper end of the hoisting trolley 4, a lifting rod 11 is arranged inside the guide cylinder 10, the lower end of the lifting rod 11 and the inner side of the guide cylinder 10 are connected by a telescopic spring 12, a front shovel 13 is installed on the upper end of the lifting rod 11, a stopper 14 is installed at one end of the traction rail 1, and the stopper 14 can push the front shovel 13 downward, a limiting frame 15 is installed on the hoisting trolley 4, when the rear hoisting trolley 4 contacts the front hoisting trolley 4, the front shovel 13 on the rear hoisting trolley 4 can be moved downward through the limiting frame 15, and a backstop 16 is installed on the hoisting trolley 4; The process of conveying materials by this device is as follows: the traction chain 2 is driven to move by the driving device, and the traction rail 1 can limit the moving direction of the traction chain 2. When the traction chain 2 moves, it can drive the pushing platform 9 to move. Under normal circumstances, under the action of the telescopic spring 12, the lifting rod 11 and the front shovel 13 can be pushed upward, so that the front shovel 13 can be located in front of the pushing platform 9. After the pushing platform 9 moves to the side of the front shovel 13, the front shovel 13, the lifting rod 11, the guide cylinder 10, and the lifting trolley 4 can be pushed. The guide wheel 6 and the bearing rail 3 can ensure the moving direction of the lifting trolley 4. When the lifting trolley 4 moves to the loading position, the staff hangs the material on the lifting hook 8, and then can drive the material to move. When the lifting trolley 4 moves to the unloading position, the staff takes the material off. When it is necessary to stop, the stopper 14 is started to run. When the first lifting trolley 4 moves to one side of the stopper 14, the front shovel 13 can be pushed downward, and the telescopic spring 12 is compressed, so that the front shovel 13 and When the pushing platform 9 is disengaged, the lifting trolley 4 can be stopped while the traction chain 2 continues to move. When the second lifting trolley 4 moves to the rear side of the first lifting trolley 4, under the action of the limit frame 15, the front shovel 13 on the second lifting trolley 4 can be moved downward and the front shovel 13 can be disengaged from the pushing platform 9. By analogy, all the lifting trolleys 4 can be stacked together in sequence, and then the movement of the traction chain 2 is stopped. The backstop 16 can prevent the lifting trolley 4 from moving in the opposite direction. When the device needs to be used again, the stopper 14 is closed, and under the elastic force of the telescopic spring 12, the lifting rod 11 and the front shovel 13 on the first lifting trolley 4 can be moved upward. When the pushing platform 9 moves to the side of this front shovel 13, the lifting trolley 4 can be pushed away, and then the front shovel 13 on the second lifting trolley 4 can be moved upward, and the lifting trolley 4 can be pushed away by the second pushing platform 9, and so on. All the lifting trolleys 4 can be moved.

[0019] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 And the instruction manual Figure 4 The stopper 14 includes a telescopic cylinder 17 installed on both sides of the lower end of the traction rail 1, a pulley 18 is installed at the lower end of the telescopic cylinder 17, and an inclined surface is provided on the front side of the front shovel 13; The process of the stopper 14 pushing the front shovel 13 downward is as follows: when the stopper 14 is started, the telescopic cylinder 17 is started to extend and push the pulley 18 downward. When the front shovel 13 moves to one side of the pulley 18, the front shovel 13 can move downward under the action of the inclined surface.

[0020] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 , Instruction Manual Figure 4 , Instruction Manual Figure 8 And the instruction manual Fig. 9The limit frame 15 includes a connecting rod 19 installed on both sides of the lifting rod 11, and square openings 20 are opened on both sides of the guide cylinder 10. One end of the connecting rod 19 passes through the square opening 20 and extends to the outside of the guide cylinder 10. A tilting block 21 is installed at one end of the connecting rod 19 located on the outside of the guide cylinder 10. A driving wheel 22 is provided on the front side of the tilting block 21. A driving rod 23 is installed at the front end of the driving wheel 22. A guide groove 24 is opened at the lower end of the driving rod 23. A guide block 25 is installed at the upper end of the lifting trolley 4. The upper end of the guide block 25 extends into the guide groove 24. A T-shaped moving rod 26 is provided above the lifting trolley 4. Both ends of the T-shaped moving rod 26 are connected to the driving rod 23. A buffer pad 27 is installed at the front end of the T-shaped moving rod 26. A fixing plate 28 is installed on the rear side of the lifting trolley 4. The front end of the T-shaped moving rod 26 can contact the fixing plate 28. The process of the limit frame 15 moving the front shovel 13 downward is as follows: when the hoisting trolley 4 on the front side stops, the T-shaped moving rod 26 on the rear hoisting trolley 4 can contact the fixed plate 28 on the front hoisting trolley 4, and the buffer pad 27 can reduce the vibration force. When the hoisting trolley 4 on the rear side continues to move forward, the T-shaped moving rod 26 and the push rod 23 can stop moving, and the hoisting trolley 4, the guide cylinder 10, the lifting rod 11, the connecting rod 19, and the tilting block 21 on the rear side continue to move forward. Under the action of the inclined surface of the tilting block 21, the tilting block 21, the lifting rod 11, and the front shovel 13 can move downward and compress the telescopic spring 12. After the hoisting trolley 4 on the front side leaves, under the elastic force of the telescopic spring 12, the lifting rod 11, the front shovel 13, the connecting rod 19, and the tilting block 23 can be pushed upward, and under the action of the inclined surface, the T-shaped moving rod 26 and the push rod 23 are pushed forward.

[0021] Refer to the instruction manual Figure 1 , Instruction Manual Figure 2 , Instruction Manual Figure 3 And the instruction manual Figure 7 The backstop 16 includes a square groove 29 located on the front shovel 13, a lifting block 30 is arranged in the square groove 29, the lower end of the lifting block 30 is connected to the lower surface of the square groove 29 through a plurality of connecting springs 31, an annular limiting plate 32 is installed at the upper end of the square groove 29, a limiting block 33 is installed at the lower end of the lifting rod 11, square through holes 34 are opened on both sides of the lower end of the square groove 29, and limiting racks 35 are installed on both sides of the lower end of the lifting block 30. The lower end of the limiting rack 35 passes through the square through holes 34 and extends to the bottom of the front shovel 13. Fixed racks 36 are installed on both sides of the upper end of the traction rail 1, and the limiting rack 35 can be engaged with the fixed rack 36; The process of the backstop 16 preventing the hoisting trolley 4 from reversing is as follows: when the front shovel 13 moves downward, it can drive the lifting block 30 and the limit rack 35 to move downward. When the pushing platform 9 is separated from the rear surface of the front shovel 13, the front shovel 13 will not continue to move downward. Then, when the pushing platform 9 continues to move, the pushing platform 9 can be made to contact the lifting block 30, and continue to move the lifting block 30, the front shovel 13, and the hoisting trolley 4 forward, and the front shovel 13 continues to move upward. However, under the action of the friction force between the pushing platform 9 and the lifting block 30, the lifting block 30 can be prevented from moving downward, and when the front shovel 13 moves downward, the connecting spring 31 is stretched. When the limit block 33 contacts the annular limit plate 32, the lifting block 30 can follow the front shovel 13 to move downward. When the lifting block 30 is separated from the pushing platform 9, due to the absence of friction, the lifting block 30 can be pulled downward under the action of gravity and the pulling force of the connecting spring 31, and the limit The positioning rack 35 moves downward, at this time, the limiting rack 35 and the fixed rack 36 are meshed. At this time, the telescopic spring 12 on the rear hoisting trolley 4 has a tendency to extend and gives the tilting block 21 a force to move upward. Since the hoisting trolley 4 on the front side does not move, the T-shaped moving rod 26, the pushing rod 23, and the pushing wheel 22 cannot move forward. Under the action of the inclined surface of the tilting block 21, the hoisting trolley 4 can be pushed to the rear side, but the fixed rack 36 will prevent the limiting rack 35 from moving to the rear side. Therefore, the front shovel 13 cannot move upward either, and then the hoisting trolley 4 can be stuck to prevent the hoisting trolley 4 from moving. When the hoisting trolley 4 on the front side moves away, the T-shaped moving rod 26, the pushing rod 23, and the pushing wheel 22 can move forward under the action of the inclined surface, and the pushing wheel 22 does not block the tilting block 21, thereby allowing the front shovel 13 to move upward, and after the pushing platform 9 moves over, the front shovel 13 and the hoisting trolley 4 are pushed to move.

[0022] Refer to the instruction manual Figure 2 , Instruction Manual Figure 4 And the instruction manual Figure 5A limiting hole 37 is opened on one side of the T-shaped moving rod 26, a fixing block 38 is installed on the upper end of the lifting trolley 4, and a limiting sleeve 39 is installed on the upper end of the fixing block 38. A limiting rod 40 is arranged in the limiting sleeve 39, and one end of the limiting rod 40 is pressed on the T-shaped moving rod 26, and a spring ejector 41 is installed on the rear side of the limiting rod 40, and a universal ball 42 is installed on the rear side of the spring ejector 41. A trapezoidal table 43 is installed on the rear surface of the fixing plate 28, and the trapezoidal table 43 can contact with the universal ball 42 and push the limiting rod 40 into the limiting hole 37 under the action of the inclined surface. The universal ball 42 is connected to the limiting sleeve 39 through a spring. When the T-shaped moving rod 26 on the rear side lifting trolley 4 contacts the fixing plate 28 on the front side lifting trolley 4, and when the rear side lifting trolley 4 continues to move, the universal ball 42 can contact with the trapezoidal table 43. Under the action of the inclined surface, The trapezoidal platform 43 compresses the spring ejector pin 41 and the spring, and the limiting rod 40 is pressed against the T-shaped moving rod 26. When the lifting trolley 4 moves forward, the fixing block 38, the limiting sleeve 39 and the limiting rod 40 can be moved forward. After the limiting rod 40 moves to one side of the limiting hole 37, under the elastic force of the spring ejector pin 41, one end of the limiting rod 40 can be pushed into the limiting hole 37, and then, when the lifting trolley 4 on the front side is not blocked, the T-shaped moving rod 26 can be stuck by the limiting rod 40 to prevent the lifting trolley 4 on the front side from being pushed away. When the pushing platform 9 pushes the lifting trolley 4 on the front side away, under the elastic force of the spring, the universal ball 42, the spring ejector pin 41 and the limiting rod 40 can be pushed in the opposite direction, and the limiting rod 40 can be moved out of the limiting hole 37. At this time, the T-shaped moving rod 26 is not blocked and can move forward.

[0023] Refer to the instruction manual Figure 1 And the instruction manual Figure 6 The pushing platform 9 includes a moving platform 44 installed at the lower end of the traction chain 2. A square hole 45 is opened at the lower end of the moving platform 44. A lifting platform 46 is arranged in the square hole 45. A plurality of positioning holes 47 are opened on the lifting platform 46. Connecting holes 48 are opened on both sides of the square hole 45. The lifting platform 46 and the moving platform 44 are connected by bolts. The different positioning holes 47 on the lifting platform 46 are moved to the connecting holes 48 and connected by bolts. The lifting platform 46 on the pushing platform 9 at the corresponding position can be adjusted according to actual needs, and the front shovel 13 can be pushed by the movement of the lifting platform 46, so that the spacing between the hoisting trolleys 4 can be adjusted conveniently.

[0024] Refer to the instruction manual Figure 6An extension plate 49 is installed on the front side of the lifting platform 46, and a rotating plate 50 is hinged at the lower end of the extension plate 49. A support block 51 installed at the lower end of the extension plate 49 is provided on the front side of the rotating plate 50. When the rotating plate 50 moves to the side of the front shovel 13, the rotating plate 50 can be rotated. After the rotating plate 50 passes the inclined surface of the front shovel 13, the rotating plate 50 can be returned to its original position under the action of gravity, and then the front shovel 13 can be pushed by the lifting platform 46. When the front shovel 13 is temporarily stopped due to an emergency, the traction chain 2 stops moving, and the hoisting trolley 4 continues to move forward due to inertia. The front shovel 13 can be blocked by the rotating plate 50, and the support block 51 can prevent the rotating plate 50 from rotating in the opposite direction.

[0025] Refer to the instruction manual Figure 1 A plurality of limiting grooves 52 are provided on the traction rail 1, and a plurality of supporting wheels 53 are installed on the traction chain 2. The supporting wheels 53 are placed in the limiting grooves 52.
