[0017] 1. The multi-floor automatic circulation flat-plate tooling plate vertical conveyor can drive the car to move through the cooperation of the lifting device, so that the transmission wheel rotates on the outside of the damping pad. Through the cooperation of the first baffle, the second baffle and the torsion spring, at normal speed, the rotation of the transmission wheel drives the rotation of the lever, and the second baffle will not affect the rotation of the lever. When the speed is too fast, the second baffle is not rebounded to its original position by the torsion spring, so that the next lever is blocked by the second baffle, so that the transmission wheel cannot continue to rotate. At this time, a large amount of friction is generated between the transmission wheel and the damping pad, which can slow down the rising speed.

[0018] 2. For this multi-floor automatic circulation flat-plate tooling plate vertical conveyor, after the overspeed protection is triggered, friction occurs between the damping pad and the driving wheel, causing a large amount of heat to be generated on the surface of the damping pad. Through the cooperation of the discharge pipe, the dry ice stored in the storage box can be connected to the outside world. The fan chases the wind in the direction of the damping pad, so that the dry ice sublimated into gas is blown to the surface of the damping pad and contacts with the damping pad, causing the surface of the damping pad to cool down rapidly to avoid danger caused by excessive temperature.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A trough 3 is opened on the upper surface of the bottom plate 1, and a conveying frame 4 is fixed on the inner bottom wall of the trough 3. The trough 3 can keep the base of the conveying frame 4 stable so that each position of the conveying frame 4 can be at the same height as the surface of the bottom plate 1 or the floor plate 2. A lifting device 5 is provided on the upper surface of the conveying frame 4, and a car body 6 is provided inside the conveying frame 4. The car body 6 makes a linear straight line motion inside the conveying frame 4 through the lifting device 5 so as to lift the goods inside the car body 6 to the specified floor height. An overspeed protection component 7 for ensuring that the car is at a safe speed is provided on the car body 6, so that the goods In order to keep the goods safe during the transportation process and avoid collision or falling of the goods causing damage to the goods, a cooling component 8 is arranged on the car body 6 to prevent the structure from overheating when the car is decelerated, so as to prevent the danger of overheating of the components and protect the equipment and goods. A first double-layer conveying device 9 is arranged on the upper surface of the bottom plate 1, and a first lifting conveying device 10 is arranged on the upper surface of the bottom plate 1, so that after the goods are transported, the pallet on which the goods are placed can return to the initial position, so that the pallet can be recycled. A first detection bracket 11 is fixed on the upper surface of the bottom plate 1, which can monitor the length, width and height of the goods to be transported to avoid accidents during transportation caused by exceeding the size of the goods. A second double-layer conveying device 12 is arranged on the upper surface of the bottom plate 1, a second lifting conveying device 13 is arranged on the upper surface of the bottom plate 1, and a second detection bracket 14 is fixed on the upper surface of the bottom plate 1.

[0027] In this example, the shape of the car body 6 is a rectangular parallelepiped with a hollow interior and missing left and right side walls, so that goods can be transported in and out of the left and right sides of the car body 6, which is convenient for storing and taking goods. A first rolling shutter door 15 is fixed to the right side of the conveying frame 4, and a second rolling shutter door 16 is fixed to the left side of the conveying frame 4.

[0028] It should be noted that the first double-layer conveying device 9, the first lifting conveying device 10, the first detection bracket 11 and the first rolling door 15 are all located on the right side of the conveying frame 4, and the second double-layer conveying device 12, the second lifting conveying device 13, the second detection bracket 14 and the second rolling door 16 are all located on the left side of the conveying frame 4. The number of the second double-layer conveying device 12, the second lifting conveying device 13, the second detection bracket 14 and the second rolling door 16 are equal and equal to the number of floor plates 2, and the positions correspond one to one, so that the goods can be transported when moving to each floor.

[0029] See also Figure 2-4In order to keep the goods safe during transportation and avoid collision or falling that may cause damage to the goods, the overspeed protection component 7 in this embodiment includes a connecting frame 701, a mounting block 702 is fixed to the upper surface of the connecting frame 701, a transmission wheel 703 is rotatably connected to the back of the mounting block 702 through a bearing, a limiting plate 704 is fixed to the outer side of the transmission wheel 703, a damping pad 705 is fixed to the left inner wall of the conveying frame 4, during the lifting process of the car body 6, the transmission wheel 703 rotates on the damping pad 705, and the rotation of the transmission wheel 703 drives the limiting plate 704 to rotate, a lever 706 is fixed to the front of the limiting plate 704, and the limiting plate 704 drives the lever 706 to rotate, a fixed plate 707 is fixed to the car body 6, and a brake assembly is arranged on the fixed plate 707.

[0030] In this example, there are two connecting frames 701 and two fixing plates 707, which are symmetrically distributed left and right about the central axis of the car body 6. Two mounting blocks 702 are distributed on each connecting frame 701, which are symmetrically distributed front and back about the central axis of the connecting frame 701. Two limiting plates 704 are distributed on each transmission wheel 703, which are symmetrically distributed front and back about the central axis of the transmission wheel 703. The distance between the two limiting plates 704 is adapted to the width of the damping pad 705.

[0031] It should be noted that the brake assembly includes a first baffle 708, and the first baffle 708 is rotatably connected to the front of the fixed plate 707 through a bearing, a torsion spring 709 is fixed between the first baffle 708 and the opposite side of the fixed plate 707, and a second baffle 710 is fixed to the lower surface of the first baffle 708. The lever 706 rotates to move the first baffle 708, so that the first baffle 708 rotates, and the second baffle 710 also rotates with the first baffle 708. When the speed is slow, after the previous lever 706 moves the first baffle 708 to the extreme position, the torsion spring 709 rebounds the first baffle 708 to the initial position. At this time, the next lever 706 has not yet engaged with the second baffle 710. 0 makes contact, so it can be lifted normally. A limit block 711 is fixed on the front of the fixed plate 707. There are two limit blocks 711, which are symmetrically distributed up and down with the central axis of the first baffle 708. When the lifting speed is too fast, the next lever 706 rotates too fast and contacts the second baffle 710 in advance. At this time, the first baffle 708 has not returned to the initial position. The next lever 706 continues to move the second baffle 710 until the first baffle 708 contacts the lower limit block 711. At this time, the lever 706 is connected and cannot continue to rotate, so that the transmission wheel 703 stops rotating and generates a large friction force with the damping pad 705, which slows down the lifting speed of the car body 6.

[0032] See also Figure 5In order to prevent the components from overheating and causing danger and to protect the equipment and goods, the cooling assembly 8 in this embodiment includes a support plate 801, a storage box 802 is fixed on the upper surface of the support plate 801, the storage box 802 is filled with solid dry ice, a support rod 803 is fixed on the left side of the storage box 802, a mounting plate 804 is fixed on the other end of the support rod 803, a fan 805 is fixed on the inner side of the mounting plate 804, a discharge pipe 806 is connected to the left side of the storage box 802, and a discharge valve 807 is connected to the outer side of the discharge pipe 806. When the discharge valve 807 is opened, the fan 805 is fixed on the inner side of the mounting plate 804, and the discharge pipe 806 is connected to the outer side of the discharge valve 807. 07. The dry ice inside the storage box 802 is brought into contact with the outside world through the discharge pipe 806. At this time, the dry ice sublimates. The fan 805 is turned on. While the fan 805 blows air toward the damping pad 705, the sublimated dry ice is blown to the surface of the damping pad 705, so that the surface of the damping pad 705 is quickly cooled to avoid danger caused by excessive temperature. The other end of the discharge pipe 806 is connected to the discharge hopper 808. The other side of the discharge hopper 808 is fixed to the right side of the mounting plate 804, so that the sublimated dry ice can be more evenly distributed when it is discharged, thereby improving the cooling effect.

[0033] In this example, there are two support plates 801, which are symmetrically distributed on the left and right sides of the central axis of the car body 6, so that the damping pads 705 on both sides can be cooled at the same time. Four support rods 803 are distributed on each storage box 802, and are evenly distributed between the storage box 802 and the opposite side of the mounting plate 804, ensuring that the relative position between the fan 805 and the discharge pipe 806 and the discharge hopper 808 remains unchanged.

[0034] The working principle of the above embodiment is:

[0035] (1) When transporting goods, first place the goods together with the pallet on the first lifting conveyor 10. The first lifting conveyor 10 lifts the goods upward so that the goods reach the upper position of the first double-layer conveyor 9. Then the first lifting conveyor 10 transports the goods to the first double-layer conveyor 9. At this time, the first rolling door 15 opens, and the first double-layer conveyor 9 transports the goods to the interior of the car body 6. At this time, the lifting device 5 is started to lift the car body 6 upward so that the car body 6 can move to the height position of the specified floor plate 2. During the lifting process of the car body 6, The transmission wheel 703 rotates on the damping pad 705, and the rotation of the transmission wheel 703 drives the limit plate 704 to rotate, and the limit plate 704 drives the lever 706 to rotate, and the lever 706 rotates to move the first baffle 708, so that the first baffle 708 rotates, and the second baffle 710 also rotates with the first baffle 708. When the speed is slow, after the previous lever 706 moves the first baffle 708 to the extreme position, the torsion spring 709 bounces the first baffle 708 back to the initial position. At this time, the next lever 706 has not yet come into contact with the second baffle 710, so it can be lifted normally.

[0036] (2) When the lifting speed is too fast, the next lever 706 rotates too fast and contacts the second baffle 710 in advance. At this time, the first baffle 708 has not returned to the initial position. The next lever 706 continues to move the second baffle 710 until the first baffle 708 contacts the lower limit block 711. At this time, the lever 706 is connected and cannot continue to rotate, causing the transmission wheel 703 to stop rotating and generate a large friction force between the damping pad 705, so that the lifting speed of the car body 6 is slowed down. During the friction process, the damping pad 705 generates a lot of heat. At this time, the discharge valve 807 is opened, and the dry ice in the storage box 802 contacts the outside through the discharge pipe 806. At this time, the dry ice sublimates, and the fan 805 is turned on. 5 blows air toward the damping pad 705, so that the sublimated dry ice is blown onto the surface of the damping pad 705, so that the surface of the damping pad 705 is quickly cooled to avoid danger caused by excessive temperature. After the goods are lifted to the designated floor plate 2, the second roller shutter door 16 is opened, and the car body 6 transports the goods to the second double-layer conveying device 12 on the floor plate 2, so that the goods can be stored on the floor plate 2. After the storage is completed, the second double-layer conveying device 12 transports the pallet to the second lifting conveying device 13, and the second lifting conveying device 13 descends to the lower layer position of the second double-layer conveying device 12 and transports the pallet to the lower layer of the second lifting conveying device 13, and then returns the pallet to the first lifting conveying device 10 along the original path for cyclic work.
