Description

Technical Field

[0001] The present invention relates to the technical field of freight elevators, and particularly to a safety device for loading and supporting a freight elevator. Background Art

[0002] A freight elevator, as a special equipment for vertically transporting goods, is widely used in various industrial factories, warehouses, commercial buildings and other places. Its working principle is that a traction machine drives a steel wire rope to make the car do vertical lifting movement on the guide rail, so as to realize the transportation of goods between different floors. In the industrial production scenario, the freight elevator undertakes the handling of raw materials, semi-finished products and finished products; in the commercial field, it is commonly used for warehouse goods turnover and shopping mall goods distribution, etc.

[0003] In the prior art, for a large-load loading freight elevator structure of CN220998847U, when a forklift drives into the freight elevator during use, the freight elevator will be subjected to the acting force of the forklift on the car. At this time, the third anti-tipping member will block the first anti-tipping member, and at the same time, the fourth anti-tipping member will also block the first anti-tipping member, thereby avoiding the situation of the car and the car frame tipping over in the hoistway; secondly, the third anti-tipping members and the fourth anti-tipping members in each landing are not connected. In this way, not only can the tipping of the car frame be avoided, but also the manufacturing cost of the large-load loading freight elevator structure can be reduced. However, when the prior art freight elevator loads goods, the freight elevator can only perform centralized loading inside the car. On the one hand, during the loading process, once the goods are overweight, it will directly threaten the safe operation of the freight elevator and easily cause failures or even accidents; on the other hand, due to the limited space inside the car, the centralized loading method limits the convenience and capacity of loading, which is not conducive to the use of the freight elevator. In addition, when the existing freight elevator loads goods, the goods are unevenly placed in the car, which easily causes the center of gravity to shift during the operation of the freight elevator, reduces the operation stability, increases the risk of the goods tipping over, and seriously affects the safe use of the freight elevator.

[0004] For the above reasons, the present invention proposes a safety device for loading and supporting a freight elevator, which can improve the safety of loading goods and the operation of the freight elevator on the basis of effectively ensuring the loading capacity and loading convenience of the freight elevator, and provides a strong guarantee for the safe and efficient operation of the freight elevator.

[0036] As Figures 1-7 shown, an embodiment of the present invention provides a freight elevator loading support safety device, including a car 1 and a car door 2. A bottom plate 3 is installed at the bottom surface of the inner cavity of the car 1. A transverse displacement assembly 4 is provided on the bottom surface of the bottom plate 3. The transverse displacement assembly 4 includes a chute 12. The chute 12 is opened on the bottom surface of the bottom plate 3 and a slide rail 13 is movably connected inside. A first threaded rod 14 is threadedly connected to the slide rail 13. One end of the first threaded rod 14 is fixedly connected to a first motor 15. The first motor 15 is fixedly connected to the bottom plate 3. A plurality of rollers 32 are installed on the bottom surface of the bottom plate 3. The rollers 32 are arranged in the same direction as the movement direction of the bottom plate 3.

[0037] In the technical solution of this embodiment, when the car door 2 is opened and the first motor 15 is started, the first motor 15 drives the first threaded rod 14 to rotate, so that the slide rail 13 moves in the chute 12 on the bottom surface of the bottom plate 3. By using the rolling of the rollers 32, the bottom plate 3 and the structures above it can move out of the car 1 together. Then the first motor 15 is turned off, and the loading operation of the goods can be realized outside the car 1, reducing the impact of overweight goods on the freight elevator and facilitating the loading operation of the goods.

[0038] A plurality of weighing devices 5 are uniformly distributed and installed on the top surface of the bottom plate 3. The top surfaces of the plurality of weighing devices 5 are fixed with the same mounting plate 6.

[0039] In the technical solution of this embodiment, during the loading process of the goods, the total weight of the goods is monitored in real time through the weighing devices 5 installed on the bottom plate 3. When the total weight of the goods exceeds the upper limit of the goods loaded by the freight elevator, the freight elevator automatically alarms, and the operator can appropriately reduce the loading amount of the goods to improve the safety of the freight elevator loading.

[0040] On the upper side of the mounting plate 6, there are two placing shells 7. On both sides of the placing shell 7, there are vertical displacement components 8. The vertical displacement component 8 includes a fixed frame 16. Four fixed frames 16 are symmetrically and fixedly connected to the top surface of the mounting plate 6 in the left and right directions. On the top surface of the inner cavity of the fixed frame 16, a second motor 17 is fixedly connected. A second threaded rod 18 is fixedly connected to the second motor 17. A connecting plate 19 is threadedly connected to the second threaded rod 18. The front two connecting plates 19 are fixedly connected to the upper placing shell 7, and the rear two connecting plates 19 are fixedly connected to the lower placing shell 7;

[0041] In the technical solution of this embodiment, the goods to be loaded are placed on the top surface of the upper placing shell 7. When a certain number of goods are placed on the top surface of the upper placing shell 7, start the second motors 17 on the front two fixed frames 16. The second motors 17 drive the connecting plates 19 to move upward through the second threaded rods 18. The front two connecting plates 19 drive the upper placing shell 7 to move upward. When the highest point of the goods on the upper placing shell 7 is flush with the top surface of the fixed frame 16, stop the operation of the front two second motors 17. Similarly, goods can be placed on the top surface of the lower placing shell 7, and the placing shell 7 can be lifted to a position where the top surface of the goods is flush with the bottom surface of the upper placing shell 7. Then, goods can be placed in the space between the mounting plate 6 and the lower placing shell 7 to realize the multi-layer placement and loading operation of the goods, effectively improving the loading capacity of the freight elevator;

[0042] Further, vertical grooves 30 are respectively opened on the side walls of the fixed frame 16 close to the placing shell 7. Connecting blocks 31 are fixedly connected to the side walls of the placing shell 7. The connecting blocks 31 are respectively inserted into the vertical grooves 30 and are movably connected between the connecting blocks 31 and the vertical grooves 30, improving the stability of the movement of the placing shell 7, thereby increasing the safety of the freight elevator loading;

[0043] A number of circular shells 9 are movably connected to the placing shell 7 in a uniformly distributed manner. A position adjusting component 10 is arranged in the inner cavity of the circular shell 9. The position adjusting component 10 includes a top groove 20. Two top grooves 20 are symmetrically opened on the top surface of each circular shell 9. Two driving wheels 21 are arranged in each top groove 20. The two driving wheels 21 are fixedly connected to the same rotating shaft 22 that is movably connected to the circular shell 9. A third motor 23 is fixedly connected to the bottom surface of the inner cavity of the circular shell 9. A worm 24 is fixedly connected to the third motor 23. A turbine 25 that meshes with the worm 24 is fixedly connected to the center of the side wall of the rotating shaft 22. A steering component 11 is arranged in the inner cavity of the placing shell 7. The steering component 11 includes an annular gear 26. An annular gear 26 is fixedly connected to the outer side wall of each circular shell 9. The same rack 27 meshes with a number of annular gears 26 in the same column. A number of racks 27 are fixedly connected to the same transverse plate 28 on one side. An electric push rod 29 that is fixed to the placing shell 7 is fixedly connected to the transverse plate 28;

[0044] In the technical solution of this embodiment, after the loading of the goods is completed, the electric push rod 29 is started according to the different weights measured by each weighing device 5. The electric push rod 29 drives the cross plate 28 to move, and the cross plate 28 drives the rack 27 to engage with the annular gear 26 to rotate. The annular gear 26 drives the circular shell 9 to rotate, completing the direction adjustment operation of the driving wheel 21 in the circular shell 9. Then, the third motor 23 is started. The third motor 23 drives the worm 24 to engage with the turbine 25 to rotate. The turbine 25 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the driving wheel 21 to rotate. The rotation of the driving wheel 21 can adjust the position of the goods on the top surface of the placing shell 7. When the data measured by each weighing device 5 on the bottom plate 3 is consistent or the deviation is within a certain range, the operation of the third motor 23 is stopped, and the stable loading of the goods is completed.
