[0052] A roller wire frame 16 is disposed on a side of the first roller wire 1 away from the lifting platform 9 , and a plurality of rows of roller assemblies 17 are disposed in the roller wire frame 16 .

[0053] Oil baffles 18 are arranged on both sides of the roller wire frame 16 , and the oil baffles 18 are parallel to each row of the roller assemblies 17 ; a motor 19 is arranged near the oil baffles 18 , and the output shaft of the motor 19 is connected to the roller wire frame 16 .

[0054] The roller wire frame 16 is a rectangle with a hollowed-out middle portion. N rows of roller assemblies 17 are arranged inside the roller wire frame 16.

[0059] Example 5

[0060] like Figure 1-Figure 7 As shown, this embodiment provides a material cross-floor transfer device, including a first roller line 1, and a second roller line 2 located above the first roller line 1; the entrance 4 of the car 3 faces the first roller line 1, and the exit 5 of the car 3 faces the second roller line 2; the first roller line 1 is connected to a first lifting device, and the second roller line 2 is connected to a second lifting device; the first lifting device is used to send the material carriage 8 into the entrance 4 of the car 3, and the second lifting device is used to send the material carriage 8 out from the exit 5 of the car 3.

[0061] The entrance 4 of the car 3 and the exit 5 of the car 3 are both provided with a height limiting frame 20 , the height of the height limiting frame 20 is less than or equal to the height of the entrance 4 of the car 3 , and the height limiting frame 20 is used to limit the height of the material on the material carriage 8 .

[0062] The line lifting frame assembly 10 includes a cylinder 21 and a lifting frame 22, the cylinder 21 is connected to a pulley 23; the pulley 23 has a plate chain 24 on the side away from the cylinder 21; the first end of the plate chain 24 is fixed to the lifting frame 22, and the second end of the plate chain 24 is fixed to the side of the second roller line 2.

[0063] The height limiting frame 20 is a gantry bracket, and materials are placed on the material carriage 8. The height limiting frame 20 is set at the entrance 4 of the car 3 and the exit 5 of the car 3, which can limit the height of the materials on the material carriage 8, so that the material carriage 8 with too much material stacked on it cannot pass through the entrance 4 of the car 3 and the exit 5 of the car 3, that is, the material carriage 8 with too much material placed on it is restricted from entering the car 3 from the entrance 4 of the car 3, and being sent out of the car 3 from the exit 5 of the car 3.

[0064] The middle of the lifting frame 22 is connected to a first fixed plate, the first fixed plate is connected to a second fixed plate, a side of the second fixed plate away from the first fixed plate is connected to a slide rail 25, a slider is connected to the slide rail 25, and the slide rail 25 and the slider are used to limit the movement of the second roller line 2 in the horizontal plane. The first end of the plate chain 24 is fixed to the lifting frame 22, the second end of the plate chain 24 is fixed to the side of the second roller line 2, and the oil cylinder 21 controls the rise and fall of the second roller line 2 through the pulley 23 and the plate chain 24.

[0065] The oil cylinder 21 provides the pulley 23 with the power to rotate. When the pulley 23 rotates clockwise, the plate chain 24 drives the second roller line 2 to rise, so that the second roller line 2 is aligned with the third roller line 6, that is, the second roller line 2 and the third roller line 6 are at the same height. The third roller line 6 transports the material pallet 8 to the second roller line 2. When the pulley 23 rotates counterclockwise, the plate chain 24 drives the second roller line 2 to descend, so that the second roller line 2 is aligned with the fourth roller line 7, that is, the second roller line 2 and the fourth roller line 7 are at the same height. The second roller line 2 drives the material pallet 8 to move in the direction close to the slope, and the material pallet 8 enters the slope and moves along the slope's inclination direction until the material pallet 8 falls on the material receiving surface, and the transport personnel take the material pallet 8 from the material receiving surface.

[0066] In this embodiment, the entrance 4 of the car 3 and the exit 5 of the car 3 are both provided with a height-limiting frame 20, the height of which is less than or equal to the height of the entrance 4 of the car 3, and the height-limiting frame 20 is used to limit the height of the material on the material pallet 8. The line body lifting frame assembly 10 includes an oil cylinder 21 and a lifting frame 22, the oil cylinder 21 is connected with a pulley 23; the pulley 23 has a plate chain 24 on the side away from the oil cylinder 21; the first end of the plate chain 24 is fixed to the lifting frame 22, and the second end of the plate chain 24 is fixed to the side of the second drum line 2. The height-limiting frame 20 is a gantry bracket, and the material pallet 8 is placed with materials. The height-limiting frame 20 is both provided at the entrance 4 of the car 3 and the exit 5 of the car 3, which can limit the height of the material on the material pallet 8, so that the material pallet 8 with too much material stacked cannot pass through the entrance 4 of the car 3 and the exit 5 of the car 3. The first end of the plate chain 24 is fixed on the lifting frame 22 , and the second end of the plate chain 24 is fixed on the side of the second drum line 2 . The oil cylinder 21 controls the rise and fall of the second drum line 2 through the pulley 23 and the plate chain 24 .

[0067] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the application. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a restriction. Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in the subsequent accompanying drawings.

[0068] It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would then be positioned "below" or "below" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0069] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
