Description

Technical Field

[0001] The present invention relates to the field of elevators, and more particularly to a high-protection elevator and a method for using the same. Background Art

[0002] In the field of cargo transportation, especially when it comes to equipment such as elevators that need to lift cargo for transportation, there are often some technical challenges. Traditional cargo lifting and transportation devices often have certain limitations in design. When placing cargo on the storage lift plate, if the center of gravity of the cargo is unevenly distributed, it is easy to cause the storage lift plate to be locally subjected to greater pressure.

[0003] In this case, the supporting structure connecting the storage lift plate will be unevenly stressed. This may also cause uneven stress on the two traction devices (such as common rope traction or other power traction devices). On the one hand, uneven stress will affect the smooth operation of the equipment, which may cause the elevator to shake or become unstable during operation, posing a safety hazard to the transportation process. On the other hand, if the storage lift plate is in this state of excessive local pressure for a long time, it may partially collapse. If the situation deteriorates further, it may even cause serious accidents such as crashes, which will not only damage the goods, but also threaten the lives of people.

[0004] In order to achieve high-protection lifting and transportation of goods with shifted center of gravity, a Chinese patent with authorization announcement number CN116534765B discloses a high-protection elevator, which can achieve high-protection lifting and transportation of logistics goods with heavy weight and shifted center of gravity (cargo with shifted center of gravity), so that the logistics box is not prone to partial collapse or even falling from the elevator due to excessive local pressure during elevator lifting and transportation.

[0005] However, since the support position of the logistics box is supported by adjusting the lifting pallets on the left and right sides, it can only adjust the left and right center of gravity offset of the logistics box, and cannot effectively adjust the front and rear center of gravity offset of the logistics box. As a result, when the elevator lifts and transports goods with a shifted center of gravity, there is still a great possibility of partial collapse or even crash due to the shifted center of gravity of the goods. Summary of the invention

[0006] 1. Technical issues to be solved

[0007] In view of the problems existing in the prior art, the purpose of the present invention is to provide a high-protection elevator and a method of using the same, which can adjust the supporting position of the connecting bracket and the supporting member on the storage lifting plate according to the center of gravity position of the goods on the upper side of the storage lifting plate, thereby further reducing the phenomenon of local collapse or even crash of the storage lifting plate due to excessive local pressure, and realizing high-protection lifting and transportation of goods with shifted center of gravity.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0045] Embodiment 1:

[0046] See also Figure 1-7A high-protection elevator comprises a bottom frame 1, which can be connected to the ground by screws, and two side brackets 2 arranged in parallel are fixedly connected to the upper side of the bottom frame 1, and a top frame 3 is fixedly connected to the upper sides of the two side brackets 2. The bottom frame 1, the side brackets 2, and the top frame 3 are fixed by screw connection or welding, so that the bottom frame 1, the side brackets 2, and the top frame 3 form a complete elevator frame;

[0047] The two side brackets 2 are vertically slidably connected to the opposite sides with connecting brackets 6, and the two connecting brackets 6 are equipped with storage lifting plates 7. The storage lifting plates 7 are structures for placing goods. The goods can be directly placed on the storage lifting plates 7. When the connecting brackets 6 drive the storage lifting plates 7 to move vertically, the storage lifting plates 7 can be driven to rise and fall.

[0048] Both sides of the upper side of the top frame 3 are screwed with traction equipment 4, which can be a winch. Two traction devices 4 are equipped with two traction wire ropes 5, and the traction wire ropes 5 on the two traction devices 4 are respectively connected to two connecting brackets 6. At this time, by starting the traction equipment 4 to reel in or unreel the traction wire ropes 5, the lifting and lowering of the connecting bracket 6 and the storage lifting plate 7 can be completed.

[0049] like Figure 1-3 As shown, the connecting bracket 6 includes two vertical slides 8 vertically slidably connected to the base frame 1, and an additional bracket 10 is fixedly connected between the two vertical slides 8. The upper ends of the two vertical slides 8 are respectively connected to the ends of the two traction wire ropes 5 away from the traction device 4. At this time, the vertical slide 8 can be driven to rise and fall by the traction wire ropes 5. The lower ends of the four vertical slides 8 are fixedly connected to linear adjustment brackets, and the four linear adjustment brackets are equipped with mounting plates 17. The linear adjustment bracket is used to adjust the distance between the mounting plates 17 and the vertical slides 8. The two connecting brackets 6 include four mounting plates 17 in total, and the storage lifting plate 7 is installed on the upper side of the four mounting plates 17, and the mounting plates 17 are connected to the storage lifting plates 7 after adjustment. When the vertical slide 8 is raised or lowered, the storage lifting plates 7 can be driven to move together through the mounting plates 17.

[0050] At this time, when the goods are placed on the upper side of the storage lifting plate 7, the weight of the goods on the storage lifting plate 7 can be evenly distributed to the two connecting brackets 6 by adjusting the contact position between the mounting plates 17 on the two connecting brackets 6 and the storage lifting plate 7.

[0051] Furthermore, the side edges of the storage lifting plate 7 are respectively abutted against the additional brackets 10 on both sides, so that the storage lifting plate 7 can be limited to the left and right by the additional brackets 10 .

The connecting rail 15 is slidably connected to the outer side of the connecting slide bar 16. When the mounting plate 17 moves, the connecting rail 15 moves on the outer side of the connecting slide bar 16. At this time, the connection stability between the mounting plate 17 and the storage lifting plate 7 can be enhanced by the connecting rail 15 and the connecting slide bar 16, and the storage lifting plate 7 can be limited forward and backward.

[0053] Among them, Figure 4-5 As shown, the linear adjustment bracket includes a horizontal rail bracket 9 fixedly connected to the lower end of the vertical slide 8, a horizontal sliding groove is provided inside the horizontal rail bracket 9, a sliding bracket 11 is slidably connected inside the horizontal sliding groove, and a mounting plate 17 is fixedly connected to the sliding bracket 11, so that when the sliding bracket 11 moves, it can drive the mounting plate 17 to move;

[0054] The sliding bracket 11 can be driven by a motor or by a cylinder. In the present technical solution, it is preferably driven by a motor. Specifically, a first motor 13 is fixedly connected to the outer side of the cross rail bracket 9, and a first gear 14 is fixedly connected to the output end of the first motor 13. A first gear groove 12 is provided on the sliding bracket 11, and a connecting groove connected to the horizontal sliding groove is provided in the middle position of the cross rail bracket 9. The connecting groove is a through groove. The teeth of the first gear 14 extend through the connecting groove to the inside of the horizontal sliding groove and mesh with the first gear groove 12. At this time, the first motor 13 can be started to drive the first gear 14 to rotate. When the first gear 14 rotates, it will push the first gear groove 12 on the sliding bracket 11, thereby realizing the adjustment of the position of the sliding bracket 11.

[0055] The length of the sliding bracket 11 is greater than 1 / 2 of the length of the horizontal sliding groove. The first gear 14 is located in the middle of the cross rail bracket 9 so that the first gear 14 can always be in contact with the first gear groove 12.

[0056] The present technical solution selects to assemble at least one horizontal adjustment bracket on the mounting plate 17, and the horizontal adjustment bracket is equipped with a support member, and the support member and the lower side of the storage lifting plate 7 are abutted against each other. At this time, by adjusting the position of the support member, the support member and the lower side of the storage lifting plate 7 are at different positions, and the load of the cargo and the storage lifting plate 7 is evenly distributed to the four vertical slides 8, so that the force of the two traction devices 4 and the four traction steel ropes 5 can be more evenly distributed, so that the load of the cargo and the storage lifting plate 7 is evenly distributed, reducing the phenomenon of large local loads distributed in the front, back, left and right directions of the elevator.

At this time, the first rotating shaft can be driven to rotate by starting the second motor 18, and the first rotating shaft will drive the first rocker arm 19 connected thereto to revolve when rotating. The end of the first rocker arm 19 away from the first rotating shaft is rotatably connected to the second rotating shaft. A second rocker arm 21 is fixedly connected to the upper end of the second rotating shaft, and a third motor 20 is fixedly connected to the lower end of the first rocker arm 19 away from one end of the first rotating shaft. The output end of the third motor 20 is fixedly connected to the second rotating shaft. At this time, the second rotating shaft can be driven to rotate by starting the third motor 20. A support member is installed at one end of the second rocker arm 21 away from the second rotating shaft. At this time, the position of the support member on the lower side of the storage lifting plate 7 can be adjusted by starting the second motor 18 and the third motor 20 in sequence, so that the support member can move in a larger range until the support member moves to the position of the corresponding center of gravity on the lower side of the storage lifting plate 7.

[0058] The support member can be a plate-like structure or a Figure 3-5 and Figure 8 As shown, the support member includes a fourth motor 22 and a third rotating shaft.

The third rotating shaft is rotatably connected to one end of the second rocker arm 21 away from the second rotating shaft, and the output end of the fourth motor 22 is fixedly connected to the third rotating shaft. Starting the fourth motor 22 can drive the third rotating shaft to rotate.

A threaded hole with an open lower side is provided inside the threaded sleeve 29. The connecting screw 28 can be threadedly connected inside the threaded hole. When the connecting screw 28 and the threaded sleeve 29 are threadedly connected together, the connection stability between the storage lifting plate 7 and the support member can be improved.

When the electromagnet 35 is energized, the magnet 36 magnetically repels each other. When the connecting screw 28 moves to the lower side of the threaded hole, the electromagnet 35 is started to push the magnet 36 upward, so that the upper end of the connecting screw 28 and the lower end of the threaded hole are connected, and then the fifth motor 25 is started to drive the limiting sleeve 26 to rotate, so that the connecting screw 28 can rotate inside the threaded hole until the connecting screw 28 is threadedly connected inside the threaded hole, and the upper side of the slider 27 and the inner wall of the upper side of the vertical sliding cavity are abutted, so that the fifth motor 25 and the threaded sleeve 29 are tightly connected together through the connecting screw 28.
